1ke, from the shaft or axle upon which the are mounted.
The principa object of the invention is to provide such a device which is simple in construction and susceptibleof a wide range of adjustment for accommodation to various requirements.
Other objects and advantages of the invention will appear in the further description thereof. 7
Referring to the accompanying drawing in which like reference characters indicate like parts, and wherein- Figure 1 is a top plan view of one of the improved pullers;
igure 2 is a side elevation,
Figure 3 is an elevation of a common belt which may be used in place of the specially designed pulling hooks, and Flgure 4 is a perspective view of one of the latter.
1 represents a cross bar, or body portion of the puller which ispreferably of narrow oblong shape in plan view, having an enlarged or bossed central portion as at 2 through which is formed an internally screw threaded hole for the reception of the externally screw threaded operating bolt 3. The bolt-3 has a suitably formed head i for convenient reception of a common wrench by which it is intended the device ma be operated. The opposite end of the be t is preferably provided with a central tit 5, or slightlyrounded or sharpened for engage- .ment against the axle or shaft from which the object is being pulled, such shaft or axle usually being provided with a central de-' pression such as is caused in the process of turning or makingof same. I
' In side elevation I prefer to make the cross bar of greater thickness in the central portion, the-lower faces of which extend ra dially therefrom, being inclined as at 6,
while the op osite face of the bar is preferably perfect y straight.
Throu h the two opposite ends of the bar and ara lel with the axial hole thereof are formed elongated slots 7 iforv cooperative engagenzent with the pulling hooks or bolts, the especially designed ones of which are illustrated at 8, there being a pair "of such hooks for each puller. The object. engaging ends of these hooks are preferably of general rectangular form in cross section, are
provided with the hook like projection 9 at the extreme free end thereof and taper sllghtly towards such free end as clearly illustrated in Figure 4 of the drawing. They are also provided with laterally projecting shoulders 10, the uppermost faces of which are slightly inclined to coincide with the inclinatlon of the cross bar, as they are made to impmge same by theti htening of the nuts 11 on the upper cy indrical screw threaded bolt portion 12'of the hooks and whlch portlon is made extendable through the slots 7 in the cross bar. By this structure it is evident that the hooks may be moved either towards or from the central .portlon of the bar to accommodate difierent sized gears or wheels being pulled and after belng once set to the proper size, for example intermediate of the spokes of the wheel and adjacent-the hub thereof, they may be drawn up tightly in such established positlOIl on the cross bar before stress is put upon the pulling bolt 3.
This feature of myinvention is considered important in that it prevents any slipping or springing of the hooks out of position when the ulling is conducted.
In Figure 3 have illustrated a common screw threaded bolt 13 which may be used 1n place of the hooks 8 which may be desirable in the pulling of gears or wheels which have holes formed in the webs thereof adj acent the shaft upon which they are mounted, when said bolts may be screwed into the threaded holes made for this purpose.
Having thus described my invention, what ilaim and desire to secure by Letters Paten 1s:
A holding member for pullers having a mam cross-bar with opposed wholly surrounded slots therethrou h, said holding member being cylindrica and externally screw threaded upon that end which is engaged within the slot in the crossbar, and
Nil
rectangular u on the opposite end, the int- D811 face of both ends of the member being ter being hoe ed for engagement with the in the same plane. 3 object to be pulled, and. a shoulder at the junction of the two difierent shapes of the (3 member, said. shoulder projecting principell in the opposite direction to that efthe Witnesses: hoe to prevent stress upon'the letter bend- S. C. BRONBON, ing the member backwerdly, the longitudi- S. Geo. STEVENS.
In testimony whereof I hereunto afix my signature in the presenge of two Witnesses.
OHN GRAHER.
