which takes the place of the tight and loose pulleys, being connected direct to the lower cone shaft. Countershaft (When & furnished) has T. L. (self-oiling loose) pulleys, 8"x3^" and should -- make 1100 R.P.M. for the alundum wheels, or 550 R.P.M. for oil stone wheels.

Fig. Figure 1126 American No. 9 Universal Knife Grinder S4 American No. 9 Universal Knife Grinder AN extremely rigid, well designed, finely fitted machine, intended for accurate results by critical users, in grinding thin hard steel knives as well as the ordinary planer knives. The frame is of pedestal form, cast in one piece, and it supports the carriage ways, the adjustable head stock carrying the grinding wheel arbor and all the operative parts of the machine. -- Capacity Made in two sizes, 31" and 37". Technical Features -- The Carriage Moves on gibbed ways by means of a rack and gear- ing and is extra heavy and rigid. Stops are provided for changing the stroke which can be adjusted when in motion. The actual extreme reciprocation of the carriage is about 3" more than the rated capacity -- of the machine, so that the wheel clears the knife at both ends while reversing. The Grinding Headstock Is gibbed down to ways planned at right angles to the carriage ways, and the arbor bearings are of the side clamping type, making adjustment easy and accurate. A. cross- feed screw is provided to adjust the wheel to the work auto- -- matically as the carriage reciprocates, and it has a hand wheel con- venient to the operator, for independent adjustments. The Feed Is entirely automatic, the reciprocation of the carriage being con- tinuous, and the forward feed of the grinding wheel is capable of adjustment from 1-1000" to 1-3000" to each reciprocation. This movement is controlled by a stop which can be set so that the wheel will cease grinding at any point, and by means of the vertical hand -- lever, the reciprocation of the carriage can be varied or stopped at any point. The Patent Knife Bar Is a new departure in machines of this class and enables the operator to grind ordinary slotted knives in the usual way, and also provides a clamping jaw to hold thin hard steel knives, which may be firmly held and ground without a separate attachment to the bar. By a special device, thin knives can be brought up to the wheel at an angle adapted to the work to be done, and they may be back ground without shifting in the clamp; there is also a special duplex index disk on the end of the bar graduated so that the approximate grinding angle may be found quickly and the exact angle afterward determined by the differential position of the two sets of graduations; this device also provides for the changing diameter -- of the grinding wheel so that the grinding angle may always be deter- mined accurately. Patent Back Stops Are attached to both the slotted knife face and the thin knife clamp, whereby the edge being ground will be kept parallel with the back, and the knife thus always -- balanced. There are many other important details, which render this machine superior to any now made. The Grinding Wheel Is 26" diameter, and cased, and provided with a water nozzle and return spout so that all emery and steel dust is carried to a settling -- tank with the water. A rotary pump supplies a large volume of water. A Countershaft -Is supplied in the base of the machine, having & 10"x4" T. L. (self-oiling loose) pulleys, which should run 300 R.P.M. There is a hand lever shifter for the main driving belt attached to the machine frame. Fig. Figure 1130 American No. 200 Automatic Self-Feed Knife Grinder A UNIVERSAL automatic machine that will accurately grind any kind of a knife or bar that will lie on a plane surface. The frame is of pedestal form, carrying two planed ways on which the carriage slides. The solidity of this construction insures per- fect grinding. Capacity-- Made in four sizes, 30", 36", 42" and 50". Technical Features -- The Knife Bar Is so shaped that the grinding may be performed either to or from the edge of the knife and a screw adjustment is pro- vided for setting the knife at any desired angle. The frame carrying the knife bar is pivoted to the carriage so that the bar may be swung -- away from the wheel to provide easy access to the knives when changing. The Feed Is entirely automatic; the reciprocating movement of the knife carriage is governed by stops so that any length of knife up to the capacity of the machine may be ground. The movement of the wheel to the knife can be regulated to grind from 1-3000" to 1-1000" to each back and-forth movement of the knife carriage. The movement of the wheel carriage when set is automatically controlled and the wheel will cease grinding at any -- We point desired. furnish one emery wheel 26" diameter, IK" face. A Pump Attachment And tank are supplied for use when wet grinding is desired. The tank can easily be removed for cleaning when necessary. If desired the pump and tank can be omitted and an -- & overhanging tank supplied at a slight reduction in price. Counter- shaft Has T. L. (self-oiling loose) pulleys, 12"x3"; speed, 300 R.P.M. Figure Figure 11341 American No. 100 Automatic Knife Grinder HpHIS machine is designed to meet the demands for a plain semi-automatic knife grinder without the automatic cross feed. It is provided with our patent combination bar for clamping either slotted or hard thin knives. The frame is a heavy cored column, cast in one piece, with broad foot flanges, making it rigid and free from vibration. Capacity--Made in three sizes, 32", 36" and 50". -- Technical Features The Carriage Has an automatic transverse movement across the face of the wheel and is provided with adjustable stops for regulating -- the length of cut, and can be instantly stopped at any desired point. The Knife Bar -For holding the knife is slotted, to receive bolts on one face and has a series of clamps by means of which hard thin knives can be securely held and accurately ground. It is fed to the wheel by a hand wheel, as shown. The knife is ground perfectly true and can be quickly set at any angle or bevel desired. The -- Arbor Carrying the wheel is of large diameter and runs in long -- boxes. One Wheel 22" in diameter by \yi" face, is furnished with each machine, and a hood is always furnished with the machine. The machine can be used for wet grinding, in which case we furnish a small water tank attached to top of hood and from which water is dropped onto the wheel. However, the machine when so equipped should not be regarded as a regular wet grinder, as no provision is & -- made to take care of waste water. T. L.

Figure 1142 American No. 1 Double End Emery Grinder ''THE accompanying cut shows our double end emery grinder, a heavy substantial machine, arranged to carry five wheels with knife grinding attachment, and with gumming attachment for small circular saws, when so ordered. The arbor is of steel, running in long boxes. It is fitted with a cone pulley, thus giving two changes of speed. One end is so arranged as to carry two or four 12" wheels varying in thickness, and the other end two 12" wheels, all having a 1>&" hole. The pulleys on arbor are 4" and 6" in diameter. No wheels are fur- nished, unless ordered at extra cost. Countershaft is furnished if desired, at extra & R cost, with T. L. (self-oiling loose) pulleys, 8"x4"; speed, 750 P.M.

We were the first in the field to apply motors to our machines and the development of successful drives has been largely due to us. The following pages specify the various types of drive for the machines illustrated in the catalog. The success of an electric drive depends very largely on We the type of control used in connection with it. illus- trate the various types applied to our machines on pages 90 to 96.

Sufficient examples are given to enable the student to arrive at a fair understanding of what is the correct position to take at some of the principal machines he will be called upon to operate. The Lathe, the Universal Saw, the Jointer and the Sander and their operation form the chief source of experimental training in the woodworking department of the manual training school. Consequently we have confined our illustrations to these machines. 103 FRONT ELEVATI0M Of AMOUCAN SPEED LATHE MOTCM DTtlVCN Front Elevation of Motor Hcadblock Lathe (American 12-Inch Speed Lathe) On Operating the Lathe The Lathe is perhaps more closely akin to the art side of the student's development than any other woodworking' machine. And, for that reason, it claims his highest interest. With it his skill in forming articles of use or beauty is challenged; for what he accomplishes depends almost entirely upon himself. That is what makes the Lathe so interesting and so essential to the equipment of the woodworking department of a vocational school. The process of turning will always form the centre of interest in such a department. \M The Roughing Cut In this illustration the student is preparing to take the roughing cut in turning a cylinder. This operation consists in removing the corners of the square piece and is done with the tool known as the gouge. m The Sizing Cut After the roughing cut has been taken calipers set tnoextthecutd.iamTehteerildleussitrreadtiownilsl hdoewtsertmhiensetutdheentdeppetrhfoorfmitnheg this operation with the cut-off tool. 10 The Paring Cut When the correct dimension has been found, as shown in the preceding illustration, the next step in the process of turning a cylinder is the paring cut or finishing A cut. This is done with the skew or bevel chisel. very thin shaving is removed by this operation, 10? Cutting the Ends This operation is performed by using the cut-off tool. It is merely taking a slice off the end. If a very thin slice is to be removed, it is usually made by the long point of the skew chisel. If it is more than a quarter of an inch it should be sized and then removed by the skew. 108 Rounding If it is desired to round the end of a piece or to produce a convex surface the operation can be done by applying the broad side of the skew chisel. This is perhaps the most difficult operation to perform if accuracy is obtained. iw Polishing This operation is done with a cloth after the cylinder has been sanded and while rotating in the lathe. In sanding, use first a fairly coarse grade of paper, No. 1 or 1J^, and afterwards a fine grade, No. or 00. Before applying the cloth the wood may be varnished lightly while the lathe is not running, taking care to wipe off all the surplus varnish. The varnish will assist in giving the surface a fine polish when the cloth is applied. no Face Plate Turning The preceding illustrations show the process of turning when the piece is supported between the live and dead centers. The process shown in the next three pictures illustrate the character of the work done with the head stock only when the piece is supported by the screwcentre chuck or face plate. The Scraping Gut This cut is properly made with the concave chisel held in such a position as to give a light scraping cut. Care should be exercised not to allow the chisel to extend too deeply, otherwise the material will chip with the grain. After the desired circumference has been obtained the surface should be smoothed with the skew chisel. in Modeling a Rosette This illustration shows the student using the rest, set at right angles with the bed or parallel with the face plate. Prior to the modeling a shearing cut should be taken with the skew chisel to face off the material to an even surface. 112 Use of the Dividers This illustration shows the use of the dividers. The student is marking off to a uniform scale the position of the various corrugations in the rosette he is turning. 113 Cutting off to Gauge with Rolling Table Roughing out a Core box with use of Ripping Gauge 114 srcctt srt+ven 44J0/A& Z4Bi� iOCX Front Elevation of Universal Saw (American No. 20 Universal Saw) On Operating the Universal Saw The operations that can be performed on the Universal Saw are so many that we shall not attempt to illustrate them all here. But enough are given to show the characteristic poses involved in cross-cutting, ripping, -- and dadoing, the three basic uses of a Universal Saw. It is a more dangerous tool than the lathe and the guard should be kept over the saw at all times, except of course, in dadoing when it cannot be used. 115 Cutting off with Sliding Gauges Making use of Dado Head 116 � Using Pulley Segment Gauge Panels made on the Universal Saw Bench with aid of the Protractor 117 . Use of Patent Bevel Protractor as Applied to American Universal Saw Bench The drawing shows a brace extending from a point 2" in one direction and 4" in another at right angles, the object being to determine angles, A B and C. The Starting Point of fence is 45 degrees or common mitre. In setting fence for the measurement, viz., 2"x4", the operator starts at 2" on the Cross Graduated Sector and then follows the 2" line, which parallels the travel of the saw until he reaches the 4" line. The intersection is marked with a star in drawing. -- Angles'. You will note that you are dividing an imaginary block 2" wide by 4 long. The fence, when set, registers an arbitrary graduation in circular arc 2j4" This gives you the acute or steep angle A. This setting also gives you the key to all angles that it may be desired to cut, and it is only necessary to remember the one point, viz., 2}4". To determine angle B, set fence 2^4" to the left of the 45 degree line. To determine angle C, start at 90 degrees and carry the fence forward two lines 2j4" > viz., 5. 118 ) Front Elevation of Hand Jointer ( American No. 1 On Operating the Hand Jointer The great variety of work that can be done on a hand jointer depends very largely upon the knowledge and skill of the operator. In this fact lies the value of -- this tool as a part of a school equipment, second only to the lathe. It lends itself to so many operations, that the student gains much in knowledge and efficiency. The five operations following, will give a fair idea of the scope of work that is usually accomplished on a hand jointer and show something of the method by which the work should be done. The Jointer is another tool when the use of the guard should never be omitted. 119 Planing out of Wind Removing corners or chamfering Making Glue Joints Rabbeting Planing a Bevel for Mitre Work 122 On Operating the Sander The Sander is an interesting machine in the school room for on it considerable "forming" can be done as with the lathe, although its prime use is to make smooth or polish. In the single illustration following, the boy at the left is forming a mitre while the one at the right is smooth- ing a surface. 123 Part III A literary education is no education. All the classics of the past cannot make men. Experience does, life does. -- Leonardo da Vinci Machine Specifications for the Cabinet Shop IN order to assist school men charged with the responsibility of writing the machinery specifications for cabinet shop equipment, we append the following pages. Any of these may be copied literally with the assurance that every important item that should enter into the construction of a high grade machine is covered completely. Of course we have used our machines as the basis for these specifications; but they will cover any other make of high grade woodworking machines as well. They are intended as a protection against the substitution of machines inferior to ours which are known and accepted in the industries as the standard. The subject Alternative Specifications given after each machine refers generally to other ways in which certain parts of American machines may be constructed and particularly to the latest methods of motor drive. 127 Specifications for Woodworking Machines 36-Inch Band Saw (Illustrated page 8) -- Capacity To take 18" under guide at its highest point and 36" horizontally.
