IULLEY REMOVER AND REPLACER.

Specification of Letters Patent.

Patented Aug. 25, 1914.

To all whom it may concern Be it known that we, lVAmnr. R. CLAY- TON and DAVID H. JONES, citizens of the The invention relates to what may be gen-.

erally termed a press particularly designed for the effective removal of gear pulleys or the like which have worked loose on their shafting, and for the equally effective replacing of such pulleys after correction necessary to correct the loose condition. As heretofore practised, particularly in the case of loose gear pulleys on loom crank shafts, the removal and replacement of such pulleys has been accomplished with drift blocks and sledge hammer, frequently breaking or damaging the pulley, to say nothing of the loss of time while the loom is standing for the necessary repairs.

One essential object of the present invention, therefore is the provision of a press, capable of operation by one man, in which the shaft can be readily and quickly adjusted, and through which the pulley can be simply and quickly removed, and as readily and quickly replaced, with the added advantage over the old method of insuring an absolutely accurate and satisfactory result.

The invention in the preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a view in side elevation illustrating the improved press. Fig. 2 is a vertical sectional view of the same, showing the press in use for displacing the pulley. Fig. 3 is a section on line 33 of Fig. 1. Fig. 41 is a section on line 4-1 of Fig. 1. Fig. 5 is a view similar to Fig. 2 showing the press in use for replacing the pulley.

The improved press comprises a frame 1 preferably constructed to provide a bed or base 2 and spaced side plates 3, secured to and rising from the base. Throughout their central portions the side plates are reduced in height as at 4 to provide space for the reception of the pulley to be removed or replaced.

The supporting frame described is that preferred in connection with the press, though it is to be understood that we contemplate any desired type of supporting frame for the purpose.

At one end of the frame, hereinafter termed the power end the upper edges of the side plates are provided with spaced bearings 5 in which is rotatably mounted a main or operating shaft 6, which shaft, while arranged for free rotation in the bearings is held a ainst independent longitudinal movement t erein. This shaft beyond the power end of the press is provided with a gear 7 whereby rotative movement is imparted to the shaft. Supported on the side plates at the power end of the press are uprights 8, provided at their upper ends with bearings 9 to rotatably support a driving shaft 10, the latter being provided with a 'drive pinion 11, arranged for operative meshing with the gear 7. The pinion 11 is keyed for independent longitudinal movement on the shaft 10, whereby it may be manually engaged with or disengaged from the gear 7, for a purpose which will later appear. The end of the driving shaft 10 is I threaded sleeve 15 is arranged to cooperate with said threaded end of the operating shaft. The sleeve is provided with a depending guide 16 which extends between the edges of the side plates, and is preferably formed with opposing depressions 17 to receive guide ribs 18 formed on the side plates, whereby to prevent independent ro tation of the sleeve, and at the same time accurately guide the same in operation.

The upper ends of the side plates 3 at the end of the press opposite the power end are, immediately adjacent the reduced portion 4 of said plates, of somewhat less height than the remaining length thereof, providing a horizontal ledge 19 and an abrupt vertical shoulder 20. The edges of the side plates forming the ledge are inwardly beveled as at 21. Two distinct blocks are designed to cooperate with the ledge and shoulder thus formed, one of said blocks as 22 being of the solid type and used when the press is the pulley resting in the recess 24 of the block A cap 28 is applied to the end of the plunger sleeve, so as to present a solid end. The handle 12 is operated causing a,

rotation of the main shaft and forcing the plunger longitudinally of said. shaft,to drive the shaft 26 through the pulley, thus removing the same. In the use of the press for the replacement of the pulley, particularly on crank shafts of looms, the block 22 is used on the ledge and the crank 29 of the shaft engaged over said block. The cap 28 is removed from the plunger sleeve, the pulley applied on the end of the shaft, and the main shaft operated to force the plunger sleeve longitudinally, said sleeve engaging and moving the pulley, while at the same time passing over the crank shaft.

It is of course to be understood that with the use of the press with other than crank shafts, we contemplate any usual or ordinary means for fixing the shaft adjacent the edge formation, considering such feature no part of the present invention.

By ar 'anging the gear 11 for independent sliding movement, we are enabled to provide a quicker return of the plunger sleeve to normal or inoperative position, as the gear may be independently operated through the handle 13 to this end.

The improved press provides a simple and effective machine for the speedy and accurate removal or replacement of pulleys or the like from shafting, the operation insuring a pressure at all times in line With the shaft and absolutely preventing any possibility of distortion or breakage of the pulley.

hat is claimed is 1. A press including a frame, a main shaft rotatab'ly mounted therein and having a threaded portion, a plunger sleeve cooperating with the threaded portion of the shaft, means for preventing rotation of the sleeve, said frame being formed with a ledge remote from the shaft, a block removably engaging said ledge to support the shaft being operated upon, and means for operating the main shaft.

2. A press of the class described including a frame, a shaft rotatably mounted in the frame and held against independent longitudinal movement therein, a plunger sleeve having threaded connection with the shaft, and means cooperating with the sleeve and held against other than longitudinal movement in the frame for preventing rotation of the sleeve in the operation of the shaft.

3. A. press including a frame, amain shaft rotatably mounted therein, a plunger sleeve having threaded connection with the shaft, a guide depending from the sleeve, and spaced plates forming part ofthe frame between which the guide projects, whereby to prevent rotary movement of the sleeve in the operation of the shaft.

4t. A press including a frame, a main shaft rotatably mounted therein, a plunger sleeve having threaded connection with the shaft, a guide depending from the sleeve, and spaced plates forming part of the frame be tween which the guide projects and guide ribs formed on said plates and seating in depressions in the guides.

In testimony whereof we affix our signatures in presence of two witnesses.
