4To all whom it may coinacm.' L Be it known that I, RICHARD WnrrAinnfa citizen 4of the vUnited Staeggresidirgat New ye-iirventedgcertain new and Brufennnty of" useful ...Improvements in`--Gasf Pumps, of'
which the following 'is a specification.
This inyention relates to improvements in I pumps forcompressin any gas, as ammonia .ga's in icesmakingmac ines, and is a division 0, 'my
January '11th, 1904. .The objects ofthe resent invention are te pplication Serial No. 188612 filed produce a pump ma e of as few parts asl possibleand connected .together by ground joints sothat packing will be dispensed with.-
Anotherobject is to improve the construction 'of theeccentric andthe lbearing of the connecting rod with the piston. -I attain'v thesefobjects `by the mechanism the accompanying drawings, in
which, 1 Figure 1 is a sectional view of -a pump similar to `that disclosed in my original application above referred t'o and embodying the resent invention, takenon the line1-1 of 1ig'. 2. Fig. 2 is a similar view taken on'the linen2-2 lof Fig. 1.
In both views', like parts are designated by the same reference characters.
The casing 1 is of the general shape shown and is provided with'a bearing 2', a gland 3, and packing rings 4 for the passage 'of thev A cover 6 having a bear-v one side of the casing by v means of stub bolts 8, the joint between it 1905, serial No.l 239,723.
`and the casing being ground or'otherwise rendered oil-tight, so that the casing willserve as a receptacle forthe lubricating oil.
The eccentric 9 is provided with integral bearing portions or stub shafts 10,.whic h are mounte within the bearings 2 and 7 any end play being prevented'A by the engagement therewith. The shaft 5 passes through theeccentric `and is secured in place by any suitable means, such as the key 11.
The outside cover 12, dished as shown, is.
applied to the cover-'6, and forms in con Junction with the cover 6, a double cover,
constituting a condensing chamber 13, as dei scribed in m original afpp ication and alsoin a division t ereof iile by me January 5,
Original application ledvkl'anuary 11., 1904; Serial No. 188,612. Divided and this application iiled January 5, 1905.

i cover 12, is referably secured in place l by the same set o securing bolts as are used ffor the inner cover.` This chamber 13 conimunicates with theinside of the casing 1 by two-or moresmall openings 14, by means of whichqthe oil will always beat the same lheight as that within the casing 1. The `chamber i3 serves the purpose of a condensingchamber and permits the escape of the ammonia gasV whihmay leak by the packing rings of the piston into the` oil casing 1. The' escapinggas maybe drawn off by means of the pipe 15, into the gas' tank and again oompressed.
The 'cylinder 16 is entirely separate from the casing, and isl 'provided with a ground shoulder 14 .which rests upon `the upper-part of the casing 1 to form a gas tight jolnt. The
cylinder is secured in-plaee upon the casing- ,by any ,suitable means, but preferably by means of a tie-bar and cross-bar, so that the parts may be separated, such asis disclosed 1n my original'application. The piston 17 is provided with a number of packing rings 18 o f the usual typev and has integrally formed .within it a cylindrical bearing 19 `which engages Witha cylindrical head 20 formedinte- .grally on the upper end ofthe connecting rod 2 1. *This bearin is in the form of an undercut'slot, 'the un er-cut .portion being cylindrical in shape and'extending completely across the piston.l 1 The connecting rodv21 is preferably cast integral with the eccentric vstrap 22. The bearings 19 and 20 are kept in proper relative position by engagement with the Walls of the cylinder no other means beingnecessary. Bymaking the cylindrical portion 20 off'a 'len th equal almost to the internal diameter o Vthe piston, and itself of considerable' diameter, asufficient bearing surface w11l be secured, so as not torequire the need of any yadjusting devices. vThis' bearing i's extremely cheap and is eiiicient in operatlon, and'may be very readily taken apart, by first removing the cylinder.
Having now described my invention what: I claim and desire to secure by Letters liat'-v ent, is
, 1. In a gas pump, the base casing constituting an oil-tight receptacle vto contain lubrieating oil, an actuating shaft extending transversely into said receptacle, an eccen tric keyed on said shaft within said recepl tions of said eccentric;substantially as set orth. r
. tuting an o1l-tigh-t receptacle to contain lubri- I transversely into said receptacle, an eccentric keyed on said shaft Within said recepgral bearing portions, the eccentric strap on i' said eccentric,
`Within' sai tacle and having at its opposite sides intel and a connecting rod rigid With said stra and having on its upper end an integral cy indrical transverse head, .combined With a cylinder removably secured upon the u per end of saidcasing, a piston cylinder having formed Within its lower portion a transverse cylindrical bearing extending through it and adapted to receive ysaid head, said head and bearing being substantially co-extensive in length with each other and the diameterof said cylinder, and said casing having bearings in its opposite sides to receive the integral bearingpor- 2.' In a gas pump, the base casing constieating oil, an actuating shaft extending tacle and having a transverse bearing in said casing, an eccentric strap on said eccentric,
and a connecting rod integral with said strap and having on the end of its upwardly extending portion an integral cylindrical transverse head, combined with a cylinder removably secured upon the upper end of said casing, a piston Within said cylinder having formed Within its lower portion a transverse cylindrical bearing extendin through it and adapted to receive said hea said head and bearing being substantially co-extensive in length with each other and with the diameter of saidcylinder; substantially as set forth.
This specification signed and witnessed this 27 day of December, 1904.
