FREDERICK W. PARSONS, OF ELMIRA, NEW YORK, ASSIGNOR TO ING-ERSOLL-RAND COMPANY, OF JERSEY CITY, NEW JERSEY, A GGRPORATION OFNEV] JERSEY,

HIGH-PRESSURE COMPRESSOR UNIT.

Application filed September a, 1921. Serial No. 498,580.

To all whom it may concern; 7

Be it known that I, FREDERICK W. PAR- soNs. a citizen of the United States, a resident of Elmira, county of Chemung, and State of New York, have invented a certain High-Pressure Compressor Unit, of which the following is a specification, accompanied by drawings.

This invention relates to a high pressure multi-stage motor driven compressor unit of the horizontal type; but more particularly to a four stage machine, having a low pressure cylinder, two intermediate pressure cylinders and a high pressure cylinder.

The objects of the invention are to afford ready accessibility to all the cylinders, permit any one cylinder and its associated parts to be assembled and disassembled without disturbing any of the other cylinders or their associated parts, eliminate certain stuffing glands heretofore required and enable more perfect alignment to be more easily obtained on a high pressure machine, enable the intercoolers to be more advantageously arranged and permit the use of longer intercoolers without adding to'the floor space, simplify the piping and obtain av better distribution of weight in the machine than heretofore.

Further objects of the invention will hereinafter appear and to all of these ends the invention consists of the features of construction, arrangement of parts, and combinations of elements substantially as hereinafter fully described and claimed inthis specification and shown in the accompanying drawings, in which- Figure 1 is a plan view partly broken away and partly in horizontal section of a compressor unit embodying the invention,

Figure 2 is a side elevation of one side of the machine, v

Figure 3 is a side elevation of the other side of the machine,

Figure 4: is an end elevation of one end of the machine,

Figure 5 is an end elevation of the opposite end of the machine, I

Figure 6 is a longitudinal sectional elevation through the low pressure and first intermediate cylinder, and I Figure 7 is a longitudinal sectional elevation through the second intermediate and high pressure cylinder.

Referring to the drawings, the machine comprises bed plates, which may be formed on a plurality of frame sections, A and B lying horizontally and parallel to each other slde by side, on asuitable foundation C. The framesections A and B, which may or may not be tied or cast together, form a substantially rectangular four cornered frame with sufficient space between the sec-i tions fora driving member D shown as a belt wheel. A main crank shaft E for the wheel Dis provided with suitable bearings in the frame sections, and cross-heads F are connected to the cranks G of the main crank shaft E by the connecting rods H. The cross-head pins F onothe cross-heads F which reciprocate, on the guides J are offset from the center line of the cylinders in accordance with my former United States Patent No. 704,914 granted to me the 15th play of July, 1902, as a preferable construc- Compressor cylinders are mounted at the four corners of the rectangular frame and these cylinders extend outwardly from, or over-hang the frame. In accordance With my preferred construction, a low pressure cylinder K and an intermediate pressure cylinder L are connected in longitudinal alignment on one frame section A, with the interposition of yokes K and L, and another intermediate pressure cylinder 0 and a high pressure cylinder P are mounted in longitudinal alignment in this instance directly on the other frame section B. Aligned piston rods Q for the piStonsK and L of the opposite pairs of cylinders K and L are connected to the cross-heads F of one frame in any suitable manner. The pistons K and L may be either singlev or double acting in this instance being shown single acting. The cylinders O and l? are preferably provided with plungers Q and Q respectively connected to the cross-head F by means of the spacer Q and the distance piece Q5 A partition plate Q forming a guide may be provided between the yoke K and the frame A, and partition plates Q may be provided between the cylinders O and P and the frame 13.

An intakepipe. Ris connected to the first or low pressure cylinder K and a discharge pipe S is connected to the last or high pressure cylinder P. i

Any suitable heads and inlet and dischargevalves may be provided for the cylinders and in this instance, the low pressure cylinder K is provided with the head T havingthe inlet and' discharge valves U and V while theintermediate: pressure cylinder L is provided with the head W having the inlet and discharge valve X and Y, only the outer covers of these valves being shown except in section. The intermediate pres"- sure cylinder may be provided with a removable head a and inlet and discharge valves of the poppet type indicated at Z and Z in the cylinder; The high pressure cylinder P is provided with the cover plate 6 within which the valves are adaptedto be located, inside of the cylinder, the discharge valve Z only being shown.

first intercooler cis mounted on the supporting posts orframes d over one frame section A and these posts extend vertically and are provided with the saddles e to the frame section B and having the saddles e to which the straps p are connected.

The low pressure cylinder K is connected by a pipe 9 to the first intercooler 0 and a pipe r connects this inter-cooler with the first intermediate pressure cylinder L. The fluid passes from the cylinder L through the connecting pipe 7' to and through the intercool'er g which is connected by'a pipe 8 to the second intermediate pressure cylinder 0. A pipe 6' connects the cylinder 0 to the third intercooler and aftercooler 70. Another pipe it connects the intercooler 7a to the high prescure cylinder P, From thence the fluid is discharged through the discharge pipe 8.

The compressor unit is driven in any suitable manner as by means of an engine or motor which may be belted to the belt whee'lfD, or if desired the motor could be directly connected to the main crank shaft E. Owing to the four cornered construction of the machine, with a compressor cylinder at each corner and the arrangement and construction of interco'olers and piping, illustrated and described, any one cylinder and its associated parts may be readily assembled or disassembled without disturbing any of the other cylinders or their associated parts. By locating the cylinders at the four corners of the frame, longer intercoolers may be provided extending substantially from one cylinder to the other cylinder in longitudinal alignment therewith and this is a. materiali advantage. Fewer stuffing glands are necessary in my construction than heretofore and the pipingis simplified and less length of piping is required, which is in more accessible position than usually provided. The weight of the parts forming, the machine is equally distributed and the machine is well balanced withoutcon'su'ming additional floor space.

I claim:
