GEORGE E. FRISZ AND JAMES D. WILTSHIRE, OF INDIANAPOLIS, INDIATTA; SAID WILTSHIRE ASSIGNOB TO SAID FRISZ.

' PULLING IMPLEMENT.

Specification of Letters Patent. Patented July 27, 1920;-

Applioation flled July 8, 1919. Serial No. 308,381.

To all whom it may concern. f

Be it known that we, GEORGE E. Fmsz and JAMES D. WILTSHIRE, citizens of the United States, residing at Indiana olis, in the county of Marion and State of ndiana, have invented certain new and useful Improvements in Pulling Implements, of which the following is a specification.

The present invention relates to wheel pulling implements of that type comprehended by our previous application, Serial Number. 242,799,. filed July 1, 1918, these improvements representing certain modifications and refinements in the structure looking toward a greater facility of operation and an increase in the general adaptation of the device for doing work along the line of removing or displacing of parts more or less diflicult of accomplishment under ordinary conditions.

More specifically, this invention provides for greater ease in the application or removal of the object engaging members or arms such that the operations aforesaid may be accomplished without the complete displacement of the means for holding them in proper position upon the body part of the puller; for the formation of the object engaging parts in such manner that turning or twisting thereof when stress is placed upon them in use will be precluded; and for other structural improvements giving greater range of application, as above premised.

This invention further comprehends a different type of clamping or gripping means from that used in the device of the previous application, the said means being so constructed that when the pulling implement is operated and engaged with it the gripping action increases as the stress or pressure is increased, thereby providing for positive engagement with the part being removed.

These and such other objects as may hereinafter appear are attained by the novel construction, combination and arrangement of parts to be hereinafter specifically described and claimed. Reference will now be had to the accompanying drawings forming a part of this specification, wherein:

Figure 1. is a side elevation of'the device showing its application for the removal of a vehicle wheel by engagement with the threaded hub;

Fig. 2 is a sectional view showing more clearly the construction of the body of the puller, especially formation;

Fig. 3 is a puller arms;

Fig. 4 is a view showing the use of the device as a portable press, including a press plate or base;

5 is a plan view of said press plate;

Fig. 6 is a fragmentary view showing the application of the puller arm to a wheel stud as when removing a wheel from a full floating axle; and

Figs. 7 and 8 are detail .views of the thread engaging clamping rings, shown also in Fig. 1;

-Fig. 9 is a sectional view puller arms.

-Throughout the following detail description and on the several figures of the drawwith reference to the slot perspective view of one of the of one of the 'ings, similar parts are referred to by like body portion of the device which consists of a heavy metallic disk having a central threaded hub 2 in which is received the pressmg member or screw 3. The screw terminates in a pointed extremity 4 and being of special tool steel this point will withstand great pressures without mutilation, said screw being operable by means of a wrench engageable with the head. It will be noted that the body 1 is formed with a series of slots of peculiar form, radial at 5 and enlarged laterally at 6 for the special purpose to be hereinafter set forth. As in our previous invention We use with this body a plurality of pulling arms 7, each tion of our present invention, 1 denotesthe in the slots 5 which conform in width to the thickness of the arms, turning or twisting or said arms will be impossible. Furthermore, the ends of each arm are bent as indicated at 9 and 10, respectively, to provide hooks for engaging the parts to be removed;

'One of these bent ends, as more clearly shown in Fig. 3, is apertured at 11 to receive cap-screws or studs of a wheel in gear or wheel removing, as depicted in Fig. 6. It should be noted, furthermore,- that the hooked ends are bent in diiferent'directions which arrangement is extremely useful because said arms ma be turned in different.

will be explained that the arms are adjustable in the slots 5 radiall or outwardly and inwardly, to-accord wit the dimension of the part or parts with which the arms are to be engaged and where necessary, or when there is any likelihood that the arms will shift or spread outwardly upon application of pressure, suchtendency ma be overcome by the use-of set screws intro uced into tine peripheral threaded openings 12, as fully de scribed and shown in our previous application. These screws are not here shown because their use is entirely apparent.

An important feature ofthe construction of the body 1 is the provision of thelaterally enlarged portion of the slots designated 6, for whenever it is desired to shift these arms 7 from one slot to another or to remove them from the device, it is only necessary to release the nuts 8 if they are in clamping position and run the arms outwardly to said enlarged portion which is of suflicient size to permit the nuts to pass through. In our previous device, one .of the nuts had to be removed, but this is now not necessary, resulting in thesaving of much time. i

The puller device as described above, when used in conjunction with a base or press plate, becomes a portable press of great power, the operation of which is simply a carryin out of the functions of the apparatus di ering but slightly from the pu ling operations. The press plate is shown in Fig. 5, denoted 13, having slots 14 at its sides and the intermediate cut-out portion 15. The arms 7 are en aged in the slots 14 in the manner shown in Fi 4, andwith this arrangement, f0r examp e, it is a simple' matter to push out the piston pin of a piston by placing the piston .on the base and exerting pressure a ainst the pin with the pressure screw 3. litany other simple operations can be carried out by this arrangement.

Passing now to another important feature of our present device and referring again to Fig. 1 of the drawings, in removin a wheelby engagement with the threa hub thereof, we employ a special clam consistin of the inner, internally thread open ring 6 of Fig. 7, the outer peripheral surface of which is beveled as indicated at 117, 8

is correspondingly beveled so as to ride upon the beveled surface 17. Thus when removing a vehicle wheel, the outer ring 18 is first slipped over the threaded hub 19, then the inner ring is screwed on to the hub a suitable distance and the outer ring en aged therewith. ,The puller device herein e ore described is now a plied by engagin the hooked ends of t e arms 7, any Suite 10 number of which may be used, over the outer ring 18 and the pressure screw 3 against theaxle or shaft of the wheel. By producing ressure with said screw, the wheel is rea ily removed, the greater. the ressure used, the greater the clamping action of the rings upon the hub, eliminating the chanceof stripping the threadsor"injuring the wheel hub. It should be understood that a ring 16 of the proper thread must be utilized to take the particular hub threads, but these are more or less-standard at the present time for numerous types of cars.

.Where it is desired to distribute the stress with the spoke or with the stud, as shown in fiaving thusdescribed our invention, what we claim. as new 1s 1. In an implement of the class described for removing wheels, pulleys, gears and the like from their shafts, the combination of a body having slots extending radially and circumferentially therein, a pressure applying member'carried by said body, and object engaging means adjustably mounted on said body in the slots and displaceable from said slots upon movement to the circumferentially extending portion thereof.
