Be it'known that I, SAMU L Lrrrnnv, a
citizen of the United States, and resident of East "Cleveland, in'thecounty of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Compressing-Engines, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to" which it appertains to make The object of-the invention is to provide a compact-powerful compressor adapted for pumping and compressing air and gas, that is taking the gas from a gasometer and pumping it nto a storage tank from atmospheric pressure up to 200 lbs, or over as required, and which is' necessary when filllng small tanks with expensive 7 gases, such as nitrous-oxld gas employed by physicians and-surgeons as an, anesthetic, or
'prestolite employed in furnishing illumination for automobiles and which must be carried in as compact-a form as possible.
The invention comprises apunip includingalternately acting high and low pressure cylinders and pistons whereby the pressure is accomplished in progressive steps and stages, thus greatly reducing the amountof power required to operate the pump and providing a compact arrangement of parts suited to the character of the work required, and such that it can be used in any ordinary laboratory without in convenience to the operator.
The construction of the pump also permits of a double use and of conveying at least two different gases or gas and air together. It is also so arranged as to provide the greatest amount of power at the end of each piston stroke where the compression is greatest.
The invention also includes means for cooling'the cylinders as they become heated by the compressed air or gas therein.
The invention further comprises means for preventing the leakage and waste of gas in the passages of the pumps, and further'includes the combination and arrange-- Specification of Letters Patent.
.co rnnssINe-nnemn Patented Dec. 9, 1919.
Application filed August 21, 1915. Serial No. 46,708;
a plan View thereof; Fig. 3 is an enlarged section of head of low pressure cylinder and Fig.4 is an enlarged section of the head of the high pressure c-ylinderyFigs. 5 and 6 are plan and side elevations respectively of the connected pistons and yoke.
In these views A is an engine frame or casing in which the operating parts are mounted, 2 is a crank secured upon a shaft 3 which is mounted upon a bearing 4 that projects at the rear of the casing, and 5 is a band wheel by means of which the shaft is'driven; 6 is'the low pressure cylinder secured rigidly to one end of the frame A, and 7 is the high pressure cylinder se cured to theframe A opposite the low pressure cylinder and in axial line therewith; 8 is the piston for the low pressure cylinder; 9 is the piston for the; highpressure cylinder; 10 and 11 are the respective piston rods for the lowfand high pressure cylinders which are operatively connected with each other by means of a yoke 12 in the same axial plane as the pistons and rods, and formed wider-at one end=thanthe other, and preferably triangular in shape, so that one end 13 thereof can enter the low pressure cylinder, and thus greatly economize the space within the casing required for itsat 16 and engages a pin 17 secured in the small end of the yoke near the piston rod 10, so that the connecting rod operates entirely inside of the yoke, except at the forked end and its weight isperfectly balanced. 1
In this manner the pump can be operated smoothly without strain or vibration since the pistons are connected in a perfectly straight line and are preferably integral with the rods and .yokes, and substantially no vibration can occur.-
, A water jacket 18 surrounds the cylinders and casing throughwhich a current of water f is maintained to cool the cylinders to prevent the pressure of air or gas from overheating them.
The end of the yoke adjacent to the small high pressure cylinder is not reduced in size since it does not enter the low pressure cylinder. The low pressure cylinder is provided with an inlet check valve '19 and inlet pipe P and with an outlet check valve 20 which leads to a pipe 2l'connecting the high and low pressure cylinde1g and provided with a check valve 22; is the receiving tank for compressed gas, or air, and the pipe 24- leads thereto from the high pressure cylinder and the rearward flow is prevented by means of the check valve 25. a V
The suction of the high pressure piston will draw into the cylinder the charge as it is compressed in the pipe by the low pres F sure cylinder, and while the low pressure piston is drawing in the charge in its cylinder the high pressure cylinder will give its additional amount of pressure to the first drawn in charge. Since the low pressure piston is much smaller than the high pressure piston the amount of power required to operate them is substantially the same and the operation will be substantially a continuous one, and the compression will be obtained in progressive stages with less claim as new and desire to secure by Letters Patent is: p
In a pump, the combination with a high and a low pressure cylinder and pistons therein, of an intermediate crank case, the cylinders each having a water jacket, and the crank case also having a water jacket, the water jacket of the crank case communicating with the water jackets of the cylinders, an inlet pipe leading into the low pressure cylinder, an outlet pipe leading from the high pressure cylinder, a pipe connecting said cylinders, all of said pipes having check valves, a pipe extending from the interior of the crank case to the inlet pipe beyond its check valve, the pistons being operatively connected together and having a common means within the'crankcase for operating said pistons, all of saidparts being adapted to operate as set forth. e
In testimony whereof, I hereunto set my hand this 19th day of August, 1915.
