' Specification 0 chine which shall occupy the minimum of floor space and otherwise shall be of compact construction, while at the same time'simple and -convenient'of manufacture and capable of ready access tothe different parts for upkeep, and of high efficiency and economy.
The compressor has been designed for torpedo charging, but is applicable to other uses where acompac't compressor, capableof operating efficiently at high speed and high compression, is required. 'For a full understanding of the invention, a detailed description of a construction embodying the same in' the best form now 4 known to me will now be given in connection with the accompanying drawings, forming a part of this specification, and the features forming the invention then particularly pointed out in the claims. I In the drawings 1 Figure ,1 is a side elevation of the machine; Figure 2 is an end elevation looking to the left in Fig. 1, and with certain parts in-section.
Figure 3 is a central section through the steam and air cylinders, longitudinally of the shaft, and I Figure 4 is an irregular section on the line 14 of F 1 with the first stage compressor head par'ally broken away ,to show the valves and the first stage cooler in section.
Referring to the drawings, the piston for 4 the first and second stages is a differential trunk iston having the head A and reduced trunk operating in the first stage chamber a above the piston, and second stage chamber 72 around the trunk. C is the third stage piston'operating in the third stage chamber 0 below it, and D is the fourth stage piston or plunger operating in the fourth stage chamber at above it.

. a 4 f Letters Patent. P te ted May directly by connecting rod 10 to steam piston E operating in cylinder F preferably. ar ranged tandem t0 the first and second stages.
/ The third and fourth stages are arranged at the side of the first. and second stages, along the two-throw crank shaft G,the differential 6 piston A, B being connected to its crank 11 .by connecting rod 12, and the third and fourth stagepistons C, 13' being carried by a single rod 13 secured tocross head 14 which 1s connected to their crank 16 by connecting rod 15. The steam cylinder F may be provided with any suitableovalve movement, a valve movement of ordinary type, actuated fromthe crank shaft G,'being indicated.
The suction;and discharge valves 1, 2 forv the first stage are arranged in the cylinder head and the discharge is through pipe 17, intercooler formed by, coils 18 in cooling chamber 19 and pipe 20 to suction valve 3 of the second stage, and the second stage delivers through its discharge valveft, discharge pipe 21 and intercooler formed by coils 22 in cooling chamber 19 to suction valve 5 of the third stage, which delivers through its dis- I charge valve 6, discharge pipe 23 and intercooler formed by coils 24 within cooling chamber'25 to the fourth stage through its suction valve 7 and this stage discharges through its discharge valve 8, pipe 26 and the aftercooler formed by coils' 27 within v chamber 25, tothe. final discharge 28. Each of the coolers is provided 'with a separating I chamber 29 having blow-off valves for the x collecting and discharge of any moisture precipitated within the coolers. v It will be seen that the invention provides a very simple, compact and convenient compressor, which is well balanced and capable of operating efficiently at a very high speed compressor shown is capable ofrunningef; ficiently at a steam pressure of 2.50 pounds per square inch non-condensing,. with a normal speed of 300 R.

and this arrangement of steam cylinder avoids the use of an additional frame, connecting rod and cross-head, and is important derstood, however, that air compressors in which the crank shaft is driven otherwise and in which less than four stages are used, may embody certain features of the invention as defined by connected to the crank shaft by a single crank.
