The free 611613 01" these jaws are provided with end-piaies or grippers'which by preference are made with sharp edges and ascrewthreaded sh'afi passes centrally through an eniarged portion 61'. the pivotally mounted head a. v

As shown in Figs. 1 and 3 the free left han. and of this shaft is aperturiad centrally to receive the pin Ufa disk bearer h which its against the end of the shaft and which in turn bears against the shaft of the gearwvheel or pulley which is, m be removed.

On the opposite and 01" this shafi h I pizzas a ratchet-whee i and a hanfi-wheal 7c, the iat'ter being 011 {ha extreme and of the shaft 109 and both (if these pai'ts keyed firmly in position. I

In Figs. 1 and 3, m represents a shaft of machine and m a gear-wheel or pulley to he pulled oil the said shaft, said parts being shown in their relation of action to the parts of my improved dcvic The pivotally mounted head 0 may be swung into downward or upward inclination according to the inclination of the shaft from which a gear or pulley is to he removed, or as shown in the drawing, this head with its jaws may occupy a horizontal position providing the said shaft from which a gcaror pulley is to be removed occopies a corresponding position. The beveled upper ends of the ribs a a? limit the swinging movement oi the head 0.

In the operation of the device of my inrprovenient the handavhccls j y with their screw-shafts g are to be rotated so as to release the jaws e and permit them to open to such an extent that their free ends pass readily over outside of a gear or pinion Such as of. "hose li:uul\ .'heels and screwshat'ts are then to be opt-rated so as to close the jaws (1 c up'agaiu;--'t the sides or opposite faces of the said gear or pinion so as to bring the end plates or grluping portions l 5 behind the op 'iosite eth cs of said gear or pinion, the jaws being thus held rigidly in place againstacridcntal displacement. The central shaft; his then revolved by means of the hand-wheel ,lwhich performs the function 01' quicl running up the cental shaft until its (,lbi lirarer [1. comes in contact with the end ol the shaft from which the gear or wheel is to he removed. The lever-handle Z is then engaged by the hand and ils pawl engaging the ratchet'svheel turns the shaft with a slow powerful motion in a direction which forces the shaft through the gear-wheel or pulley, while the same is being held by the pivoted jaws. f

This position is shown in Figs; 1 and 3, and in which the said pulley m aln )st pulled oil' the enlarged portion oi the shall on which it had been 'l'orced. .1 the same time that the pulley or hill is released from the shaft the pawl h is swung over and the lever device operated to rot e the central shaft /2. to an appreciable 1 5111 so as to release the f-ttitlt from its grip upon the shaft. after which the hand-whwl fl: nu

ill! turned rapidly so as to draw the in tral shalt quickly out ol the way. 'l'ho goal or pulley then to he engaged by a suitable device and the jaws released by the n1anu ally actuated hand-wheels f g and their screw-shafts f 5 and these movements are to be repeated with each gear-wheel or putley pulled. off its shaft.

The base or standard may he securely fastened to a. floor or the same may be heavy enough to maintain its position and 1 prefer that lllt jaw end-plates or grippers be reniovably secured to the tree jaw end-faces as shown in lfig. it, because should they be damaged or broken they can be easily removed and replaced by new parts, and furthermore it is quite essential that these jaw end-plates or grippers should he of harder metal than is necessary for the rest of the machine and their removability and separation is an essential. feature because of the tempering and special treatment required for these parts.

In i 6 and 7, I have reproduced the parts shown in Fig. 3, and to which I have added the devices I prefer to employ for pulling or forcing a. pinion or pulley on to its shaft. These comprise the long arms or rods 72 n" at one end connected to the outer ends'ot' the swinging head 0 bypivotshafts T 8. The other ends of these rods are screw-- threaded and receive the adjusting nuts and ushers 9 10. l provide a cross-head 0 With open jaw ends 0 to fit reuiovably upon the rods a a forward of the nuts and washers 9 l0. 'lhiscrosshead 0 is made with an enlarged cennfal recess and apcrtured portion to receive the pinion or pulley and pass over the shaft. 7

in Fig. '6 r. represents an armature of any motor device, 1 its shaft and r a pinion. One end of the shaft isag' ainst the'disk bearer hi and the'pinion at the other end bears against the inner face of the recess of the head 0 and the operation of turning and advancing the screw as hereinbefore described Forces the shaft 1' along and pushes the pinion onto the shaft. and into position.

The head 0 is readily lifted ott of the rods 2/: n and said rods with the short shafts 7 8 are ad vantageousl y removed from the swinging; head 'er the use of the devices in pulling oil a pinion or pulley from its shaft as hereinhetore described. V "lhedevice of my improvement is to be made in various sizes, adapted for small, light and heavy work. even such small work as the pulling of watch and clock pinions off oi their shirts and such heavy work as the pulling of gears and pulleys oil of main or armature shaf s in various styles of motors; also and as hereinbciore described the device of my improvement is adapted to pull or force a pinion or pulley on i s shaft.

1 claim as my invention: 1. 'lhe combination with a suitable base to rest upon a tloor or foundation, of a head pii'otally mounted thereon, jaws pivotally roiniected to the head and movable therewith,

w-shaft n'iovable in the head, means asl with the screwehalt for rotating 1 and means connected to the head up the jaws to the work and hold lag ti sin in position.

2. The combination with a suitable base to rest upon a-fioor or foundation, of a head. mounted thereon, said head having an aper tured and threaded center and recessed ends, jaws pivotal'ly connected tothe head in the recessed ends, bearings in the ends of said head, screw shafts passing through said bearings and operative against the said jaws,

' a main screw-shaftfassing through the apertured center of sai head and means for rotating the same.

3. A device of the character described,

comprising a base composed of a lower plate and parallel vertically disposed ribs, an intel-mediate stiffening web, bearings formed in the upper portion of the said ribs and a pivot shaft passing therethrough and across. between the ribs, a head having adepending o'rtion perforated for the said pivot sha t, the head being mounted in the. base between the said parallel ribs and adapted to, swing on the pivot shaft, means for limiting said swinging movement, a screwshaft passing centrally through the head,

means for rotating the screw-shaft, jaws pivoted to the head in the same horizontal plane as the screw-shaft and devices connected to the head adapted for setting up the jaws to the work and holding them in position, whereby the head may be brought into alinement with the work and assume the same indevices con- 5. In a device of the character described,

'ne combination with a suitable base, of a head, a screw shaft mounted in the head,

means for rotating the screw shaft, long rods and short shafts for pivotally mounting said rods at one end to the ends of the head, cross-head with jaws to fit re 'movably upon said rods and with an open center and enlarged central recess for receiving a shaft and engaging itspinion or pulley for pulling the same on the shaft, and means on the rods to resist the thrust of the cross-head.
