UNITED STATES PATENT OFFICE.
JOSEPH MCDOWELL GAMEWELL AND JAMES .AILB'EIRZIT KIRBY, OF SPARTANBURG, SOUTH CAROLINA.
HYDRAULIC PRESS.
To all whom 'it may concern:
Be it known that we, JOSEPH M. GAME- WELL and JAMES A. KIRBY, citizens of the United States, and residents of Spartanburg, in the county of Spartanburg and State of South Carolina, have invented certain new and useful Improvements in Hydraulic Presses, of which the following is a specification.
Our invention relates to improvements in hydraulic presses, and it consists in the combinations, constructions and arrangements herein described and claimed.
The object of our invention is to provide a device which is intended to be used primarily for forcing off gears and pulleys from broken or defective loom crank shafts, in cotton or woolen manufacturing plants, and for forcing the same on to a new shaft.
A further object of our invention is to provide a press in which certain parts are arranged to receive the crank shaft and other parts to bear against the gears or pulleys to be placed 011 the shaft or to be removed.
Other objects and advantages will appear in the following specification and the novel features of the device will be particularly pointed out in the appended claims.
Our invention is illustrated in the accompanying drawings forming part of this specification in which:
Figure l is a side view of the device showing it in position for forcing ofi' a gear and pulley from a shaft; Fig. 2 1s asimilar view showing the device in position for forcing a pulley and gear on the shaft; Fig. 3 is a central vertical section through the device, and Fig. 4 is a plan view of the device.
In carrying out our invention, we provide a base A which is designed to rest upon the floor B, being secured thereto by means of the bolts C. This base A is cored out at a to provide a cylinder for the piston D.
Secured to the base are the uprights E and F. The former has a reduced portion 6 which passes through a portion of the base and which is secured by means of the nut G. The support F has a similar reduced portion f which is secured by means of the nut H. A heavy casting K is adjustably secured upon the uprights E and F by means of a set screw 70. The uprights E and F are provided with holes e and f at intervals, into which pins 6 and f may be placed for hold- .3 Specification of Letters Patent.
Application filed December 27, 1909.
Patented Aug. 2, 1910. Serial No. 535,135.
ing the casting against the great pressure exerted by the piston. The piston is cored out for a portion of its length, as shown at d, to receive a pin or plunger M. The latter is also cored out at its lower end m to receive the spiral spring S.
The pump is shown at P. The plunger rod 79 of the pump is provided with a swivel joint J and is pivotally attached to the handle W.
T is an oil tank which is connected with the pump by a pipe t. The pump, in turn, is connected with the cylinder a by means of a tube or flexible connection Y. A branch pipe 6 leads from the pipe Y into the tank T, and is controlled by a valve V.
From the foregoing description of the various parts of the device, the operation thereof will be readily understood.
In Fig. 1 the end of a crank shaft L hearing a gear R and a pulley U is placed in the opening (I in the piston D, the pin M being forced down against the spring S. The upper end of the shaft L extends through a recess it in the casting K. The latter is brought down next to the gear R and is held in place by the pins 6 and f Now, when the handle W is operated, the oil is forced through the pipe Y into the cylinder a. The pressure of the piston forces the shaft L upwardly until the gear and pulley are free of the key a, when they may be removed. Now, by turning the valve V, the oil is forced back by the weight of the piston and the shaft and the gears may be removed.
Fig. 2 shows the position of the parts when the gear and pulley are to be replaced. The pin M is first removed from the piston D. The spring S normally keeps the end of the pin projecting above the top of the piston as shown in Fig. 3, so as to facilitate its ready removal, the spring being compressed within the bore m when the pin is forced downwardly. The end of the shaft is placed as before, in the cored end of the piston D, the gear and the pulley having been placed on the shaft, the latter in contact with the piston D. A steel key N is inserted through a crank Z of the shaft L under the shoulder of a recess 70 in the casting K. This prevents the upward movement of the'shaft. Now, as the piston moves upwardly, the bottom of the shaft enters the bore d, while the gear and the pulley are forced into place, the key 7" being placed in position and the pulley and gear being turned so that their key Ways will register with the key.
The device, as described, may be also used for forcing the joints of steel rollers together when the latter have been broken and repaired, in place of driving the tight fitting male and female parts together by hand with .a hammer, as in the ordinary manner.
It will be seen that the construction described above is very simple. One of the important features of this device is that the standards or uprights E and F, together with the casting K may be entirely removed by merely unloosening the nuts G and H. The device may then be used as an engine jack. On replacing the uprights on the casting and securing the nuts the machine is ready a ain for use as a means of forcing gears ofi or on shafts. It is in the simplicity of the machine that the merit largely lies, the device having few parts as stated above.
Vi e are aware that other forms of the device based upon the same general principles might be made, but We consider as our own all such modifications as fairly fall Within the spirit and scope of the invention.
