Application filed February 8, 1926. Serial No. 86,718;
This invention relates to com ressors, en-' gines and other devices of the ind including a cylinder, cylinder head and crank casing which are all necessarily made gas tight for the required operation of the dev1ce.
The object of the invention is to provide a construction in which the cylinder and crank casing may all be cast in one and yet the parts are so formed, arranged and combined thatthe cylinder and crank shaft bear ings may be -properly bored in the beginning and that all the parts may be readily disassembled for reboring, renewal or repairs.
The advantages of the invention will ap- 16 pear more fully as I proceed with my specification.
In the drawings Figure 1 is a view representing a vertical 7 central section of a compressor made in accordance with my invention in the plane of the crank shaft.
Figure 2 is a View on a somewhat smaller scale similar to Figure 1, showing the parts as they appear when disassembling.
Figures 3, 4, 5, and 6 represent parts withdrawn from the casing in the act of-disassembling.
Referring now to that embodiment of the invention illustrated in the drawings :10
indicates the casing of the compressor as av gral base and bottom 13. The crank casinghas cast integrally with it an inwardly extending tubular boss \14 which provides support for a bearing for one end of the crank shaft. The cylinder part 11 of the casting is made with integral, annular, vertically spaced bosses 15, 15, which are bored to receive a sleeve 16. Said sleeve has an annular top flange 17 adapted to rest on the uppermost boss 15, with its top end flush with the top end of the cylinder part 11 of the 7 main casing.
The side of the casing 10, opposite the crank shaft boss 14 has a comparatively large annular opening 18 defined by a flat faced boss 18*. 19 indicates a plate adapted to close against ,said' faced boss and provided 59 with an annular shoulder 19 adapted to engage within the opening 18 in the casing. The plate 19 is apertured for the crank shaft and is provided on its inside face with a tubular boss 20 which is'in axial alignment with the boss 14 of the casing. Tubular bushings 21, 22, fixed respectively within the bosses 14 and 20,\provide bearing for the crank shaft 23. A second plate 24 engages the outer face of the plate 19 and is secured with said plate 19 by cap screws 25 to the annular bosses 18. Said plate 24 is provided on its outer face with a tubular inte- .gral cap 25 which surrounds the crank shaft 23 and presents a housing and back-stop for a coiled spring 26, which engages through a ring 27. against an annular shoulder 28 on the crank shaft to hold said shaft against a ball thrust bearing 29 within the boss 14. A disc 27 of bronze or other suitable material, fixed to the ring 27, and a gasket 27, are enga ed between the plates 19 and 24 (a recess eing provided between said plates to receive them, as shown in Figure 1) to seal the crank case adjacent the ring 27.
30 indicates the flywheel fixed to the shaft 23. 31 indicates the piston and 32 indicates 11 of the casing by means of cap screws 39.
In order to take down the com' ressor, the cap screws 25 are withdrawn sufliciently to disengage them from the boss 18. The plates 24 and 19 with the eccentric shaft 23 and its eccentric 36 (as shown in Figure 6) are then withdrawn laterally from the casing 10 through the opening 18,it being understood that the opening18 is made of sufiicient diameter to permit the eccentric 36 to pass through it in such manner. The cap screws 39 are then withdrawn and the cylinder head 38 (see Figure 4) and the. valve late 37 (see Figure 5) are removed. The piston 31 and sleeve 1.6 are then pushed upwardly beyond the upper end of the cylinder partll of the casing,-the connecting rod 32 being moved up with them, until the pin 34 has been raised above the end of said cylinder part. The sleeve 16 (see F igure 3) is then'withdrawn from the piston and, after removin one of the split rings 34, the pin 33 is wit drawn from the piston, as indicated in Figure :2. This disconnects position shown in dotted lines at 40; after which it maybe turned about as indicated in dotted lines at 41, when it may be withdrawn through the openin 18 of the casing.
To reassemble the parts, t e procedure just described will be repeated in inverse order. The advantages of a compressor or like device of the construction and arrangement as described will be apparent to those familiar with the art. Not only is a stronger casing provided, but the danger of leaks at-the places where a casing made in several parts are secured together is entirely eliminated. Manitestly the invention is capable of use not only in the manufacture of compressors but also in the manufacture of like devices including a reciprocating member,- piston and crank case,
. While in describing my invention 1 have referred to many details of construction and arrangement as embodied'in the preferred form of the invention, it is to be understood that the invention is in no way limited thereto, except as may be pointed out in the appended claim.
I claim as my invention I A compressor or the like comprising an integral casing including a cylinder part, a crank case part and a base closing the crank case part, the crank case part having an inwardly extending integral bearing boss on one side and anopening opposite said boss, a bearing plate with a fixed bearing boss thereon adapted to close said opening, an eccentric shaft having bearing in said bosses and being capable of removal through; said opening, a thrust bearing in said casing boss, a resilient thrust bearing in said bearing plate boss, and a retaining plate for said resilient thrust bearing secured to said bearing plate. i
In testimony that I claim the foregoing as my invention, I aflix my signature this 1st day of Februar 192G.
