To all whom it may concern.:

llc it known that we, PETER here, DON- ALD (fonc, and Emmer L. FinasoLn, citizens of the lnited States, and residents of Can-f ton. in the county of Stark and State of` (lhio, have invented certain new and useful Improvements in Ammonia- Compressors; and we do hereby declare the followin' to he a full, clear, and exact description of the invention.

The present invention relates to improvements in animoma-compressors, the object of which is to provide means and devices which will maintain the cylinder cool by the incoming ,gas and at the same time pro vide means whereby a compound or double action is produced.

With these objects in View the invention consists inthe novel features of construction and combination and arrangements of parts which will he more fully hereinafter described and pointed out in the claim.

In the accompanying drawing: Figure 1 is a vertical longitudinal section of the cylinder ilhistratingir our improvements properly arranged with reference tosaid cylin der. Fig'. Q is a sectional View taken on line y Fig. 3 is a transverse section taken on line 3HE, Fig. 1. Fig. 4 is a View of the cylinder showing' parts broken away, also showing one of the heads and caps de tached. Fig;A 5 is a horizontal sectional view of the chan'xbered head showing the feed pipes properly located.

Similar numerals ot' reference indicate corresponding parts in all the figures of the dra wi rigs. l

ln the accomtmnyinpr drawing, 1 represents the cylinder proper, which cylinder is 'Formed of any desired size, reference being had to the capacity of the con'ipressor and as shown it is provided with the integral hase 2, designed to be properly connected to the foundation or hase plate 3.

7Within the cylinder 1 is located the piston rod el, which piston rod is reciprocated by any wellv known and common means. Upon the pistonr #t are securely mounted the pis tons 5, which pistons carry the piston rings G, said rings areeach provided with the seat Yflanges 7 and the cushion rings 8, but these parts within themselves 'form no specific part of this invention and we lay no claim l to the specilic and detailed construction oi,l

thc pistons and their different parts.

Around the cylinder 1 is hicated the chamber fl, which chamber is iaiclosed by the integral casing 10, and the outer Wall of the cylinder 1. lhetcasinpr 10 is provided with the valve connecting 'flange 11, to which is connected the valve 12,. said valve being of any ordinary construction and from which valve leads the ordinary 'Feed pipe, which is extended to and connected withthe coils of the refrigeration chambers. rllhis pipe is not illustrated as it will he understood that an ordinary feed pipe is to be employed,

lt. will he understood that the gas (pieta temperature as possible during the time the cylinder is heini;1 filled andthe gas compressed and hence it is ot' importance that provision he made for maintaining, the cylinder at as low a temperature as possible l and this invention has more specific reference in keeping the cylinder at a low temperature. For this purpose of keeping the cylinder at. a low temperature the central or intake portion ot' the cylinder covered with a layer of suitable insulating mate-rial, such as cork, sawdust or asbestos 13, over and upon which is placed a metallic sheet connected to the casino' 1() or its equivalent. The endso the cylinder 1 are closed hy means of the chambered heads l5 and 16 to which heads are connected the caps 17, said caps and chamhercd heads being so `arranged with reference to each. other that water can be forced through said chambered heads as hereinafter described, To the'caps 17 are connected the cold water pipes 18, which cold water pipes lead to any source of supply and may he provided W1th cut off valves 19 of any desired construction.v The chanihcred heads and 16 may be provided with the Webs 20, which webs are for the purpose of interrupting the rapid flow of water and at the same time presentintf;- a `greater cooling surface, said webs also serving the purpose for strengthening the heads.

For the purpose of causing water to enter weh of the wells 20, two pipes 21 are provided, which pipes are connected b the cross passage ways 22 formed in the cap 17. When the chamhercd head becomes filled with water or practically so it is conveyed from the hea, hy means of ille outlet pipes 2?, located upon opposite sides ot' the upper wel 20 and thence conveyed to the pipes Q4,

upon opposite sides of the lower or vertical erahly ammonia) should he kept at as 0W l to which pipes are connected the spray pipes 2:. said spray-pipes being located directly oxr and above the o utcr end portions of the cylinder' l. jFor the ,purpose oi causing the water to iliow i'n a sheet erlfeitream of a width practically equal to the length of the pipes 25 the escape or over low slots 26 are lo` cated in the top or upper sides of the pipes For the purpose of removing the water after it has performed its function the drain pipes 27 are provided7 which drain pipes lead to any desired place. For the purpose of observing the overflow of the water, the pipes 27 are provided with the open sided couplings 28, which open sided couplings provide over-flow passages if there should be any backine up of the water. For the purpose of collecting the water thatV passes from the pipes 25, the ianges 29 are provided, which fianges retain the water and guides the same to the drain pipes 27. Between the pistons 5 and through the shell of the cylinder l are formed a series of intakerv ports or passages 30, through which the gas passes into the cylinder and as the pistons are moved back and forth or reciprocated the gas will be compressed and forced through the valves 3l and thence conveyed through the pipes 32 to the condensers. The pipes 3Q are or should be provided with the ordinary valves 33. It will be understood that aiter the gas has been thus compressed it is in a heated condition, hence the necessity of returning it to the condensers. The valves 3l are so constructed that they will be closed except'at such times as the pressure is sufficient to overcome the tension of the springs 34, and the back pressure, at which time the valves are open.

It will be understood that by forming two pistons and mounting them upon the piston rod,^and locating the intake ports between the pistons the gas will be compressed alternatelyat the opposite ends of the piston, thereby producing practically continuous compression. In order that the gas may pass through the pistons 5A during What might be termed their backward or idle strokes the piston rings 6 are so connected that there will Le a slight relative morement as between the pistons proper and the rings thereby allowing the seat flanges to be disconnected from the seat faces of the pistons,

In Fig. 1 the piston rings are shown seated and unseated or in other words the pistons closed and opened. This feature however fornis no specie part of my invention except that it is necessary to provide pistons that will l1iot compress the gas during their backward or idle stroke.

It will be understood that liquid and sediment will accumulate from time to time and settle in the bottom of the chamber 35 and for the purpose of removinv this the stop cocks 38 may be provided. letween` the extreme end portions of the cylinder-1 and the central or what might be termed middle portion of said cylinder there ,are spaces that will not become heated as rapidly or to -as high a degree as the outer end por tions and hence it is unnecessary to provide any means for cooling said parts'other than atmospherically cooling' and hence the pipes` 25 are not necessarily extended to the ends of the middle or ipsulated portion of the cylinder.

It will be understood that the pipes 25 should be protected and hidden and inorder to provide for this the casing 3G is provided. For the purpose of providing easy access to the pipes 25 the casing 3G should be provided with the removable-covers37.

Having fully described our invention what we claim as new anddesire to secureI by Letters Patent, is-

In acompressor of the class described, a-

eylinder having a chamber extended vfor a portion of its length, intake ports'formed through the cylinder, said chambered portion of the cylinder provided with insulation and portions of said cylinder atmospherically exposed, chambered heads provided with webs adapted to close the ends of said cylinder, water pipes leading to and from the chambered heads1 a piston rod 'and piston located thereon, said piston adapted to open and close. substantially as and for the purpose specified. In testimony that we claim the above, we have hereunto subscribed our names in the' presence of two witnesses. i' PETER NEFF. DONALD `COLE. ,l ELBERT L. EBERSOLE,v` f Witnesses: Y
