Application filed December 8, 190,2. Serial No. 134,419. (No model.) n
.To a/ZZ whom, itY may con/cern:
Be it known that I, ALvA J. FISHER, a citi- -Zen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements .in Cooling Devices for Internal -Combustion Engines, of which the following is a speciication.
to operate-as-self-acting air-compressors.
An object of my invention islto 4provide im-m proved means whereby the piston-rod. of an' internal-combustion engine may be carried directly through theeXplosion-chamber of the engine.
Another object of my inventionis to shorten,
lighten,lcheapen, and make more efficient an engine of the construction described.
Another object of my invention is to provide an improved form of self-cooling water-jack- Y eted piston-rod. Y
These and such other objects as may hereinafter-appear are shown in the accompanyingv drawings, in whichf .Figure 1 shows my preferred construction j I let and discharge valves, which are not shown,
of a self-acting air-compressing internal-combustion engine. Fig. 2 is a sectional plan view thereof on thesection-line indicated in Fig. 1. Figs. 3, 4, and 5 are enlarged sectional details, Fig. 5 being a section on the line 5 5 of Fig. 3. Fig. 6 is a detail sectional viewof a modiiication. Fig. 7 is a sectional detail of the parts shown at the rightend of Fig. 3, showing the piston at the eXtreme of its outward stroke; Figs. 8 and 9 are details of modified forms of -my invention. Fig.V 10 is a side elevation of .a modification, and Fig. ll is a plan View of Fig. 10 on the line ll ll of Fig. 1.0.
Like characters of reference indicate the same parts in the several figures of the drawings.
Taking for illustration a gasolene-engine, A is the cylinder-casing, provided with the usual water-jacket at B and provided at each end with cylinder-heads C C of a usual type, said cylinder-heads being also water-jacketed at b.
` tion.
-with a head and intake. and discharge valves Fitted within the cylinder is the piston-head D, dividing the interior of :the cylinder into two explosion-'chambers E and F, respectively.
The engine is provided with anyV familiar and convenient type of apparatus for charging the explosion-chamber with-charges ofexplosive materiaL-for igniting the same at proper intervals-*and for taking care of the exhaust, &c., these details forming no part of my'in- A.vention, and being familiar to those skilled yin this artthey are notV here shown. In the embodiment of my invention shown inthe-drawings theA piston-rod Gr extends through a stuffing-box H and a gland I in the piston-head C and. connects with a yoke J, to which cranks leading tothe ily-wheels are attached in a familiar manner. In like manner the piston-rod K extends in the oppositedirection through. a stuflng-box L and gland M .in thepiston-head 0"; but instead of connecting with a yoke, &c.", it extends beyond the piston-head C and through a gland N, a stuffing-box O in one head P of the air-pump cylinder Q, and into the piston-head R, fitted within thel air-compressing cylinder. This cylinder is water-jacketed atq in a familiar manner and is provided lwith any suitable inas the same constitute no part of my inven- 'Ihe air-compressing cylinder .is fitted at each end thereof, soas to be a doubleacting compressor. Screwed into the piston-head- K and extending'therefrom in a direction-oppo- `siteto. the piston-.rod K is a piston-rod S, -Whichendsina stufling-box .yokeL the piston-rod G being closed at or adjacent to this end-in any suitable manner` as, for instance, in the manner shown at the right end of Fig. 3, where it is screwed into a socket in the yoke J and against` vany suitable packing-ring. rIhe stuffing-box -T upon the end of the rod S is mounted upon a tube U, which is mounted at one end within a casting V and extends through the piston-rods S K G and ends, preferably, within the pistonrod G at a point beyond the inner face of the cylinder-head C. This tube U is of considerably less diameter than the piston-rods S K G, so that an annular water chamber or space is provided between the tube U and the piston-rods. Y y
The end of the tube U, secured within the casting V, communicates with a chamber e, from which an outlet-port leads to the waterpipe W. X is a tube oii' smaller diameter than the tube U, which connects at one end directly with a supply-pipe Y, provided with a oneway check-valve y, which allows water to flow into thepipeX. The pipeX extends through the pipe U 'for substantially its entire length, as shown in Fig. 3.
The discharge-pipe W is `provided with a one-way check-valvel w, arranged to allow the passage of' water therethrough from' the chamber e. This pipe connects with the waterjacket q of the air-.compressor cylinder Q, while the pipe Z leads from the Water-jacket g of the compressor Q to the water-jacket B of the engine-cylinder A. From such waterjacket the pipe ,a leads and may be arranged, if desired, to connect with a tank from which the water-supply is drawnthrough the pipe' Y, thus arranging a complete circulation which 'l y will permit the same water to be used over and over again without waste, c
As so arranged, my device operates asfollows: Taking the position shown in Fig. 2 as the initial position of the parts, the first movement of the piston-head D to the right will carry the piston-rods S` K G with it, (see Fig.
l7,) and these hollow rods, acting as a pump,
will draw through the pipes Y X sufficient Water to `fill the chambers within the piston- "rods and within the pipe U. Consequently the piston-rods K G where they pass through the explosion-chambers E F, in which they are subjected to a high degree of heat, are internally water-jacketed and /are thereby kept suiciently cool for the operation of' themachine. As an explosion within the chamber F carries the piston-'head D to the left, and with it the hollow piston-rods S K G, the water-chamber within the piston-rod G beyond be seen that the water assit first comes from the tank is used to internally water-jacket the piston-rods K G, which are subjected to the highest degree of external heat and which it is most important to keep cool.
In Fig. 6 I have shown a modification of my device, showing the parts broken away, as in Fig. 3, the parts of the device between the broken sections in Fig.v 6 being substantially the same as like parts shown in detail in Fig. 3. In this modification the casting V is elongated, so that the chamber fr', while serving the same purposes as the chamber e in Fig. f1, is elongated so as to form a cylinder or barrel, upon the endof which is mounted a stuffing-box T', through which the hollow pistonrod S reciprocates. By this construction I obtain a larger pump, and so an increased iiow of water through the piston-rod and the waterjackets, and I am enabled toI dispense with the tube U, thus simplifying the device and at the same time increasing its elfectiveness without departing from the spirit of my invention.
In the modification shown in Figs.l 10 and 11 I also dispense with the tube U, as well as with the chamber fu. The feed-pipe Y passes into the casting V2, where it connects with the pipe X. This pipe projects through the stuifing-box T, mounted on the hollow piston-rod S, and into the piston-rod S a distance slightly greater than the length of the stroke of the piston. In this modification instead of hav- G terminate within the cross-head J it continues through the cross-head, which I shall pipe W leads into the bottom of' the waterjacket q, from which the pipe a' leads to a point of discharge or to the supply-tank, as may be preferred. W ith this arrangement a simple and direct circulation through the piston-rods, Water-jackets, and piston-heads is obtained, as with this arrangement I prefer to make the' piston-head D hollow, and I obtain a double-pumping action-that is, in the hollow piston-rod S and in the chamber or pump 6` In Fig. 9 I have shown the engine A arranged to be made single-acting, in which event the cylinder-head C is dispensed with, the tubes U and X terminate short of' the piston-head D2, and I supply a pitman G in place of the piston-rod G.
In Fig. 8 I have shown another modification, in which the tube X is dispensed with and the tubeU is connected, by means of a T-coupling, direct to the supply-pipes W and Y.

Other modifications will suggest themselves to meet various conditions and exigencies of shop convenience without departing from the spirit of my invention.
