Part I is devoted to the description of American Woodworking machines for vocational schools. Part II has to do with the operation of some of the machines with the view of helping the student to a better understanding of the correct position to take at the various machines he will be called upon to operate. Part III is of primary interest to the teacher or director of vocational work, especially to those on whom fall the responsibility for specifying equipment for their schools. The guiding principle in the construction of our machines rests solely on the nature of the work they are to perform. Our engineers are constantly seeking the highest requirements of the trade and making improvements accordingly. We have kept pace with the highest developments in electrical drives. The direct application of both A. C. and D. C. motors to saw arbors and cutter heads, as illustrated in this catalog, are original and exclusive with us. When a motor goes on an American machine it becomes a part of the machine itself (see our Headblock Lathes, Jointers, Saw Benches and Surfacers); you will find no clumsy makeshift arrangements here. Please file this book where you can get hold of it when you need anything in woodworking machinery. American Wood Working Machinery Company Rochester, N.

The roof of green becomes a roof of gray, The sturdy trunk the pillars of a home. They fashion us the infant's cradle, they Are part of every threshold, every room. The chair we dream in by the cheery fire, The board at which we gather for the meal, The bed to which our weary limbs retire, And everything we know and love and feel They shape from fallen forests for our need Yea, even that last room in which we rest. When we lie down to rest at last indeed, The woodland's sainted lily on our breast. Theirs not the dust of mines, the grime of toil In sweaty shops of steel and molten brass Theirs is the scent of sawdust and of soil The song of waters, wind across the grass. In everything they make for us they leave The wooded upland and the quiet shores, Yea, into every article they weave Some memory of God's great out-of-doors. --Douglas Mallock In American Lumberman.

No sticking Simple, substantial, practical design Beveled guide plates on both guides Open construction insures free movement. No clogging The Newell Automatic Saw Guide TN the Newell Automatic Saw Guide the grinding members, instead of being rigid as in all other guides, have a swinging movement which allows the back of the saw to swing freely while the teeth are held practically stationary. With these Guides the operator can force the saw around the shortest curve without kinking or straining it. Deep cuts can be made straight from top to bottom without dishing out, thus enabling the operator to saw close to the line of his work without spoiling it or making a lot of hand finishing necessary. The swinging movement of the Newell Guide compels the saw to follow true to the line of pressure. Any tendency for the saw to deviate causes the guide to react upon it immediately, thereby correcting the deviation. There is great economy in the use of the Newell Guide inasmuch as the saw breakage as compared with any other guide is considerably reduced. Combination Band Saw Filing, Setting and Jointing Machine THIS is the only machine made that performs the two operations of filing and setting the band saw at one time. This places it in a class by itself, there being none similar to it on the market. The powerful elliptical movement of the filing arm, working between heavy adjustable bronze slides, guided by vertical rods set at an angle, is mechanically perfect. It gives each tooth a clean, sharp cut, and can be so delicately adjusted as to leave the teeth without a particle of burr. All teeth are filed and jointed to an exact uniform height and size. It means less breakage of saws, longer life, quicker work, and smoother and better cutting. The setting device not only sets the teeth perfectly, but also each tooth in such a way as to allow the proper clearance behind the cutting edge. All wearing parts are made of steel, and the vise, through which the saw passes, is steel lined. The time it takes to file, set and joint band saws in one operation, is only a fraction of the time occupied in hand filing. Standard files, \y2 " extra slim taper or 7" slim taper, are used Figure 1260 American Band Saw Brazer THE illustration shows a new device for heating the joint with a flame and blowpipe, which overcomes the objections to the old method and is proving very satisfactory in practice. The Saw Blade is beveled or "scarfed" for the lap, on the table, which is machined true on the face and back, and suitable damps hold it while being operated upon. The Blowpipe is supplied with air from a double-acting pump with receiving chamber, fitted with good leather valves and double-cup piston packing. The capacity of the pump is much greater than the requirements, and very little exertion is needed to get sufficient heat to braze saws }i" wide. The Lamp is attached to the machine, and has a very large ellip- tical wick, giving a long, steady flame which becomes hottest at the point where it is forced against the saw by the air blast. Kerosene is used for fuel. The Brazer is made ready for use by simply clamping it or screw- We ing it to a bench and attaching the blast hose. furnish brazer complete, one piece of hose, a quantity of prepared spelter and pulverized borax, some fine tying wire and full directions for braz- ing with either spelter or silver solder. The time required for scarfing down the ends of the blade, adjusting it and completing the braze is from eight to fifteen minutes, dependent on the width of the blade and skill of the operator. Figure American Filing Wheels, Vises and Scarfing Frame OF the ordinary appliances for keeping saws in order, we have filing wheels and studs, two sizes of filing vises, brazing and scarfing frame with tongs. The Filing Wheels and studs are made plain but serviceable, and We are designed to be attached to a bench, as indicated in cut. do not furnish the plank shown. The wheels are covered with heavy canvas, and the right-hand one adjusts horizontally to strain the blade. The Vises are made with jaws either 10" or 18" long. When an outfit is ordered we furnish the one 10" long unless otherwise stated. There are adjustable stops in the vises, so that the blade will not sink when filed. The jaws are planed true and will grip the whole length of the vise. The Brazing and scarfing frame for holding the saws when they are to be joined can be placed in the vise or screwed to a bench, which- ever is the most convenient. The entire outfit is simple and all that is necessary where a small amount of this work is to be done. Fig. , Figure 5221 American Scroll Saw PHIS machine is intended for furniture, sash, door and blind factories, carriage and pattern shops. It is made with either stationary or tilting table. It runs at a high speed without jar. A brass pump with rubber tube is supplied to keep the saw blade cool and blow the dust away. -- Capacity Any thickness up to 12". y H" 14" long; Vs", " 2 and , 16" long. Four saws yi" Technical Features -- -- Table -Made of iron; size, 36"x38". Strain The strain is a new and practical design, permitting a high speed and an even tension on the blade at all points of the stroke. Variation in the amount of -- tension can be put on the saw by applying a crank (which is furnished) to the square end of shafts. Under Guide Ways These aie so con- & -- structed that their expansion when warm does not tighten the cross heads, which is an important feature. Tight Loose Pulleys 6"x3"-- 1200 R.P.M. Fig. Figure 5241 New American Self-Contained Jig Saw THE New American Self-Contained Jig Saw is for use in all kinds of woodworking plants where interior and exterior irregular sawing is to be done. Being self-contained, it is more rigid than the usual style of machine where the strain head is fastened to the ceiling. -- Capacity Length of stroke 4". 36" from saw to column. 10" can be cut under the guide. Blades from 12" to 20" can be used. Technical Features W %" Four saws are furnished: , 14" long: H", and SA", 16" long. -- The Column Has wide foot flange and three-point bearing on the -- floor, insuring rigidity.

The -- height of the entire machine is 7' 7". It is also provided with iron swinging drawer for extra saws, wrenches, etc. Straining Head Having no links, pivots or levers to wear and get out of alignment, makes a perfect self-contained strain. There are two large coil springs used for the tension and a wrench is provided to apply to the square ends of the spring shafts to regulate the amount of tension required. A long retracting spring is used to counterbalance the movable part of the head and the straining device can be raised or lowered and locked in position by an eccentric lever for different lengths of saws. It is also provided with a brass plunger pump which furnishes a blast to free the work from dust. All sliding parts are adjustable and the bottom end of the pitman is fitted with babbitt bushing.

Pul- -- ley, 8"x7", speed 3000 to 3400 R.P.M. Sight feed oil cups are provided. Feed Works Consist of an endless-feed chain in the table with pressures above to keep the stock in firm contact with the chain. There is an in-feed and an out-feed pressure roll of large diameter. The in-feed roll is driven, thus making it more positive in entering stock for straight ripping. Rolls are horizontally mounted on hinged arms and have independent vertical adjustment with spring pressures applied to each. This affords flexibility that per- mits the stock to enter the rolls easily. The arms of both the in- feed and out-feed rolls can be adjusted so they can be kept in perfect alignment with the saw and the feed chain. The saw and rolls are entirely enclosed making an efficient suction hood. The hood is ad- justable on a screw with ball bearing end-thrust operated by an over- head handwheel and has graduated scale to indicate height of the rolls. There is also a kick-back or sliver guard back of the in-feed- ing roll which makes a complete protection for the operator. The front of the roll hood is provided with a sight that indicates the A location of the saw for sighting the cut. section of the circular hood for the saw can be removed for changing saws by loosening two hand wheels and the suction pipe does not have to be removed. Three rates of feed, usually_60, 120 and 160 lineal feet per minute are provided. Quick change of feed is made, without throwing off the power, by lever at the left of operator. Binder lever controlling the feed is at the right of operator. The driving mechanism on the right side of the machine for the endless feed chain and in-feed roll -- consists of steel roller chain and feed pulley which are entirely en- closed. Table Is fitted with an endless chain which travels on an independent bed plate with the wearing surfaces lined with steel. It can be adjusted vertically to insure perfect contact with the stock on the table. The adjustment is made by hand wheel and screw from the in-feeding end of the machine. The front end of the bed is also adjustable, transversely to and from the saw. This insures perfect alignment with the saw at all times. Sight-feed oil cups are -- provided at the right-hand side of frame for lubricating the chain. Countershaft (furnished as an extra) Is provided with tightener & for drive belt with 12"x8" T. L.

The construction is such that an entire roll can be taken apart and reassembled in a few minutes. Sections and drivers are -- of hardened steel. Roll shafts are held down by long range tempered steel springs adjustable for tension. Feed Drive Is by belts in the high speed portion of the transmission, hardened steel roller chains for the intermediate, and cut gears for the rolls or slow portion. This makes for simplicity, economy of power and smooth action of the -- rolls, all necessary conditions for a high grade planer feed. Cylin- der Is of hard forged steel, triangular with three knives or round with thin knives if desired. Journals are 2%" diameter, care- fully ground and lapped. Boxes are of the side clamping type with automatic circulation of oil and emergency oilers in the caps. Pneumatic cylinder pulleys 5"x5K" are clamped on to conical bearings. Ball bearings can be furnished at an extra price. They consist of two pairs of bearings to each journal with steady -- collars between each pair and ample facilities for oiling, the require- ments being much less than for the babbitt bearings. Chipbreaker Is made solid or sectional to correspond with the in-feed roll. It adjusts in grooves concentrically to the cylinder and can be lifted out when -- required. When made solid, it can be lipped with flexible steel. Sections are of hardened steel. Pressure Bar Hangs close to the cylinder and is adjustable at either end by finger wheels; it is ordi- -- narily made yielding, but may be rigid and adjustable in height when so ordered. Bed Plate (In three sections) is machined on entire surface; the center section lies under the cylinder and is removable for any purpose; the in-feed and delivery sections are usually slightly below -- the line of the cylinder bed, but can be adjusted to suit conditions. Main Bed Is supported on heavy inclines, which move on tracks cast upon the frame. The machined surfaces are scraped to a bearing and ample provision is made for oiling. The adjustment for thickness is made by means of two square threaded screws coupled together and operated by a large central hand wheel and cut gears. Knife Jointing and Setting Attachments-^Are extra and consist of a permanent slide bar secured to the frame over the cylinder on which the setter and jointing slide move and may be pushed to the end of the slide bar when -- not in use. When ordered a knife grinder can be put in place of the jointing plate, usually motor driven. Motor Drive For belted planers we can furnish a special motor with extended shaft to receive pulleys at each end to drive the cylinder. This can be located on the floor behind the planer or overhead. For simplicity and economy of room and belting, we recommend our new directly attached motor secured to the cylinder on a taper with holding nut. Motor frame is bolted up to a supporting bracket directly attached to the machine frame and is adjustable to concentricity with the rotor. Counter- shaft--Has T. & L.

Two knives are regularly furnished. Technical Features -- Feed The feed rolls are set as close as possible to the cylinder, and the upper in-feed roll is fluted and is held down by adjustable spring tension attached to equalizer bar. All the rolls are Zyi" diameter and the two upper ones are driven by gearing. The feed gearing is strong and well arranged and is driven direct from the cylinder; there is a binder -- pulley and lever for starting and stopping the feed. Cylinder Is a solid H" steel forging two-sides tapped, with bearings 1 diameter and 8" long, carefully ground and boxes scraped to them, so that they will not heat on starting if properly oiled. If desired a round head can be furnished, without charge, and also a knife setting and jointing
