escape, forms an elastic cushion which prevents any strain on the valve stem, and holds the valve in perfect equilibrium. The downward stroke being completed, the incoming gas no longer presses open the valve, and, by the combined action of the spring and the imprisoned cushioning gas, it is instantly sealed. i The steel of which the valves are made is of an especially fine grade, and is the only metal we have found that would successfully withstand our very rigid tests. il 26 HERCULES IRON WORKS, CHICAGO THE STUFFING BOX. The leakage of ammonia, even if so slight as to cause but little expense, is always an annoyance. Confined as it is in the pipe system, in endless coils without the possibility of escape, the only portion of the plant needing careful attention to guard against leaks is in the stuffing boxes of the compression pump piston rods. As the cut on the opposite shows, our stuffing box is of unusual depth, but with whatever care it may be designed, engineers are aware that frequent attention is required in all ma- chines to keep the packing set up enough to prevent leakage, and still not so much as to induce heating and the consequent cutting of the rods. The “Hercules” stuffing box is under perfect con- trol of the engineer at all times. Its geared connects with a short rod extending through the frame, by turning which the engineer is enabled to regulate the pressure upon the packing to any extent while the pump is in motion. Should a trace of ammonia be observed, the leak can be instantly stopped by a slight turn of the handle attached to the end of the rod. To guard against leakage of ammonia we have, in addition to the very long stuffing box mentioned above, applied the method of continuous of the piston rod shown in the engraving. Two oil chambers are provided, and packing placed as indicated, the piston ro freely and with trifling friction through tight stuffing box. BUFFALO, N. Y., HOUSE 35 TONS MACHINE.

AVING considered the engine, compression pumps and other machinery forming that portion of the plant which is in motion, we pass to the second division, or the “ ConpEensiInG” side, composed wholly of piping. The ammonia—leaving the compression pumps, hot, compressed, but still gaseous—reaches the Con- denser, which should be conveniently located on the roof of the building. In the “ Hercules” system the Condenser is divided into two parts, namely: the PRELIMINARY ConpeENseR and the Liqutrier, as shown in the illustration on the opposite page. The gas when discharged from the compressor passes into a trap, where oil, scale, etc., are de- posited ; from the trap it passes into the Preliminary Condenser, which is located a little lower than bottom of the Liquifier. After being cooled to a con- siderable extent in the Preliminary Condenser, it passes out to the Liquifier, where it is cooled to a liquid. The cooling water first passes on to the Liquifier pipes and drops over them, absorbing what- ever heat the gas contains. It then flows from the Liquifier into the trough where the Preliminary Con- denser is located. After thus performing a double duty in condensing ammonia, the water can be used —in ice machines—for condensing steam. at 32 HERCULES IRON WORKS. CHICAGO. The foregoing is a description of our Open “ Air Condenser, but we also furnish a Su j Condenser, composed of an iron tank, with con- densing coils within it, wholly submerged. The water passes into the tank at the bottom, and flowing — over the Preliminary Condenser performs a double duty, as in the open air condenser. When the ammonia is Liquified it flows into the receiver, where it is ready to perform the work of cooling, cither by expanding into coils in tanks, or by ex- panding into coils in rooms to be cooled. Our divided form of condenser possesses marked advantages, and is a great improvement over the old method of arrangement still in use by all other manufacturers. The warmest water meets’ the hottest gas, and, as it has already performed duty on the Liquifier, it is used on the Preliminary Con- denser without expense. * ‘The manufacture of the condenser and other pipe systems used by us has received careful attention. We have fitted up a special department for the pre- paration of our pipe systems, all pipes being care- fully welded and bent into endless coils by ci machinery. All condenser coils are made fi extra heavy special drawn pipe, and the coils are tested under many times the pressure the will ever be subjected to in actual use.

HE ammonia which left the compression pumps and entered the condenser as a gas through a large pipe, now leaves the con- denser in a pipe from one-half to one inch in diameter, and enters the third general division of the system, there again to expand into its original gaseous condition. Whatever heat it has lost in the previous process of condensing, it will regain from whatever surrounds it when allowed to expand. If we desire the expanding ammonia to extract the heat directly from the rooms in which the articles to be cooled are placed, it is conducted as a liquid into the rooms and there allowed to expand into a system of pipes placed on the ceiling or walls as may be most suitable. This is called the Direcr Expansion system. In erecting a machine under the Direct Expansion system we use the greatest possible care. Well aware that destruction of property might result from the escape of ammonia, we take every known precaution, and we can assure our patrons of the same safety under the Direct Expansion system as under the brine system. Extra strong pipe, welded into as long lengths as can be handled, and coupled beyond a pos- sibility of a leak, is used in all cases. Heavy wrought iron headers receive and distribute the ammonia to the circulating pipes in each room, and steel valves regulate its flow. The solidity and unusual strength a 36 HERCULES IRON WORKS, CHICACO. which characterize the machinery portion of the “Hercules,” as already explained, have been care- fully followed throughout the entire pipe system. Ina large proportion of the machines for refrig- erating purposes, the Brine System is preferred. Where brine is used we furnish steel brine tanks, heavily strapped with steel angle and “T” beams, insulate them in a thorough manner, and, when in an exposed position, lagging them handsomely with wood. Endless coils of pipe are placed in the tanks, the ammonia being admitted to them through steel expansion valves. Standard brass lined, duplex steam pumps draw the brine from the tanks, and circulate it through the piping of the rooms to be cooled, from: which it flows back to the tanks by gravity when it has absorbed a sufficient quantity of heat to need recooling. An important advantage of the Brine System is, that the cold brine filling the storage rooms and tanks can in many cases be circulated by the pump for several hours after the machinery is stopped, and still be sufficiently cool to keep the rooms in proper condition. In that way the necessity of running the machine continuously is avoided, We are advocates of both the Brine and the Direcr Expansion systems in their proper places, but prefer in all cases to make a careful inspection of the premises and the work to be accomplished, before advising customers which system to adopt. In the manufacture of ice the Brine System is invariably used, the details of the manner of its application being given in the next chapter.

HE manufacture of artificial ice is a test which a good machine should not fear, but which will at once show the weakness of a poor one. There are none of the recommen- dations of the “ Hercules” in which we take more pride than those referring to ice making. Some of our competitors prefer to let ice making alone, con- fining their trade to refrigerating only. The ease of knowing daily the exact amount of duty the plant is developing is distasteful to the manufacturer who rates his machine far above its capacity, and his exaggerated statements when making the sale are sure to be brought up and an explanation asked when the expected daily number of blocks of ice are not produced. To make good ice from the various waters offered throughout the country requires not only a good machine, but large experience and technical knowl- edge as well. We have never failed in any instance to produce pure ice, as solid and clear as crystal, and have in all cases given our customers every pound called for in their contract. Users of the “Hercules” Ice Making Machine write us that they are producing the “best ice,” and those using our ice find its purity all that they could desire. a9 CHATTANOOGA ICE & BOTTLING C CHATTANOOGA, TENN, Bees 3 id el 25 TONS ICE MAKING.

In close proximity to every statement will be found its full corroboration by our customers. Not only have we never failed to make our guarantee upon the formal test at the time of acceptance, but the daily running afterwards in the hands of those who do not profess to he experts, has exceeded the guaranteed duty in every case, and our customers are, without exception, enthusiastic in their praises of the “ Hercules.” In conducting our business we act on the principle that what a man does himself is well done. The entire management and control of our business is in the hands of active, practical men, fitted by many years of training for the respective departments they control and who personally supervise all details. We give customers our individual attention, ascer- tain their wants, and adapt arrangements to meet their various requirements. We are absolutely free from all combinations or other entangling alliances. We own our own works and patents, attend strictly to our business, and sell a 42 HERCULES IRON WORKS, CHICAGO. our machines at as low a price as is consistent with — honest work. By dealing directly with our customers __ we avoid employing traveling men under large sala- ries, and by constructing all parts of our machines in our own works we produce the completed machine at the lowest possible cost. The benefit of this low cost of production and the small cost of making sales we give to our customers, and are placing the “ Her- cules” on the market at a price as low as that offered by the makers of cheaply constructed rival machines. We shall be pleased to receive full particulars from parties contemplating the purchase of machines, and will give such inquiries prompt and careful at- tention, personally inspecting the premises whenever desirable, and making such suggestions as our ex- perience may dictate. The rapid and satisfactory growth of our busi- ness has been wholly due to the excellence of our machine, and to our strict attention to our customers’ interests. In the future we shall be governed by the same policy. The “Hercules” will keep pace with the requirements of the day, and will be found at all times to embody all the latest improvements, and our customers need have no fear that their interests when placed in our hands, will receive other than the — most careful attention.
