Application filed September 4, 1323. Serial No. 860,535.

To aZZ ii /i011; it Hljlr/ concern.

Be it known that .l, ll' inms W. Linens, a citizen ojl the- United States, residing at Salisbury, in the county of Rowan and St: a of North Carolina, have invented certain new and useful .lniprovenients in .ll ydraulic Presses tor Crank Shafts and the like, of which the following is a full, clear, and exact description. 1 i

The present invention relates to apparatus for removing or applying pulleys, gears and the like to loom crankslu-ii ts, and has "for its object to provide such a. device which is simple in construction, and yet which is thoroughly reliable and etlirient in ope tion. lVhile the invention is designed p marily for use in connection with looiu shatting, it should be here noted thatthe same is equally well adapted for reii'ioving and applying bushings, collars, roller necks or other elements requiring a tight fit Other objects and advantages of the invention will be apparent from the following description when taken in connection with the accompanying drawings, in which:

Figure 1 is a side elevation oi? the conr ple-te apparatus.

Figure 2 is a plan View thereof.

Figure 3 is an end view of the apparatus slightly enlarged, and

Figure 4 is horizontal section taken in line 4-4 of Figure 1.

Referring to the drawings more in detail, the numeral 1 indicates the legs of a supporting frame or bed Which. are braced by the longitudinal side braces 2 and crossbars 3, Secured to the upper end of the legs 1 are the main frame or body members 4 which form a track or guideway for the crosshead 5. This crosshead is provided with sleeves 6 at the opposite ends thereof which adapts the crosshead for sliding movement along the guide bars 4. Mounted on the crosshead 5 adjacent the sleeves 6 thereof are pawls 7 which are pivoted for co-operation with notches 8 in the upper sides of the bars 4. The adjacent ends of the bars 4 are rigidly connected by means of fixed crossheads 9 and 10, the former being provided with a groove or notch 11 in alignment with notch 12 of the movable crosshead 5 for a purpose to be later described.

Mounted on one end of the frame is a fluid pressure cylinder 13 provided with a piston and piston rod (not shown), to the latter of which is secured a plunger or rain 14, This piston is operated by hydraulic pressure,

and to this end I have provided a tank l5- jacent the base of the legs 1. These pumps are operated through the medium ot' coir nccting rods 19 WVlllCll are connrcterhby means o'teccentrlc straps 20 with theecccir 'trics 21 mounted on shaft 22. Power is'applied to the shaft 22 by means oi the hired and

loosepulleys

23 and 24, on which is mounted a belt 23, the latter being con trolled in the usual manner by a belt shift 25.

Extending from the pumps 18 are pipes 26 and 27 which are coupled together at 28 to receive the upwardly extending pipe 29 which leads to a four-way valve'30. This valve is controlled by alever 31 to which is connected a stop arm 32 having its opposite end extending through one of the legs 1 and provided with

stops

33 and 34. Leading from the valve are

pipes

35 and 36 connecting with opposite ends of the cylinder 13, while, pipe 37 leads from the valve 30 back to the tank 15.

Suitable check valves

38 and 39 are placed in the pipe system, and a pressure gauge 40 is connected with the cylinder 13 in the usual manner.

In the operation of the device the crosshead 5 is adjusted to a proper distance from the plunger 14 by means of the pawls 7, and the loom crank-shaft or other piece of machinery A having a pulley or the like to be removed is then placed lengthwise of the apparatus and rests in theinotches 11 and 12 of the fixed and movable crossheads 9 and 5, respectively, with the pulley in engagement with pins 41 which engage the side of the crosshead 5 and are united by the lateral brace 42 which has its ends resting on the guide bars 4 as clearly shown in Figure 2. Valve lever 31 is now moved so as to open the passages from tank 15 through conduit 17 pumps 18,

conduits

27, 28, 29 and 35 to the adjacent end of the cylinder. Such position of the four-way valve will, of course, connect pipe 36 with the return pipe 37 to the tank 15, permitting the liquid to eX- haust from that end of the cylinder'to the tank 15. The belt shifter 25 being operated to put the belt onto the fixed pulley 23, the pumps 18 are operated to force fluid under pressure into the cylinder, thereby forcing out the ram 14 so as to engage the adjacent end of the shaft to be operated on and force the same free from the pulley or other element to which it is attached. By reversing the valve it will be obvious that the ram li will be withdrawn.

When it is desired to place a pulley or gear Wheel on a shaft the latter is placed in the notches 11 and 12, as shown in Figure l; and in order to prevent longitudinal movement of the shaft a plate 44 is placed in the pocket 43 and engages the crank portionof the shaft. A pipe or cap 45 which is closed at its outer end is placed over the end of the shaft A and engages the pulley or gear wheel which is to be forced on to the shaft. The fluid pressure is now turned on the apparatus and the plunger 14 is forced into engagement with the pipe or cap 45 and thus presses the gear wheel into place on the shaft. It will be understood, of course, that plate 4A is detachable and is merely placed in the pocket 43 when the apparatus is to be used in forcing a gear Wheel or pulley on to a crank shaft.

From the foregoing description it will be seen that I have devised an exceedingly simple arrangement of hydraulic press and frame which may be readily controlled by a single operator and which will save much of the time now required in removing and applying pulleys and the like.

In accordance with the patent statutes, I have described what I now believe to be the best embodiment of the invention, but I do not wish to be understood thereby as limiting myself or the scope of the invention, as many changes and modifications may be made without departing from the spirit of the invention; all such I aim to include in the scope of the appended claim.

What I claim as new and desire to secure by Letters Patent is: I

In a hydraulic press, a pair of spaced, horizontal bars provided with notches, a

fined and a movable crosshead mounted on plunger.
