Description
Nov. 25, 1924- S. CHINN WHEEL FULLER Filed July 17. 1923 Patented Nov. 25, 1924.
UNITED STATES SAMUEL CHINN, OF OXNARD, CALIFORNIA.
. WHEEL Application filed July 17,
To all whom t may conocia.'
Be it known that SAMUEL CHINN, a citizen of the United States, residing at Oxnard, in the county of Ventura and State of California, has invented certain new and useful Improvements in lVheel Pullers, of which the following is a specification.
This invention relates to certain new and useful improvements in wheel pullers or the like, and aims to provide a device of this kind having simple and durable parts capable of convenient adjustment whereby the device may be employed for use upon various kinds of work.
An object of the invention is-to generally simplify and improve devices of the above kind whereby the same may meet with all of the requirements for a successful commercial use.
Another object is to provide adjustable pulling arms embodying removable swiveled work engaging sections detachably engaged with inner arm sections whereby the desired ones of a plurality of sets of outer sections may be interchangeably employed with the same inner sections of the arms, thereby supplying a tool which will meet the needs of any machine shop and at a. minimum cost.
lVith the above general objects in view,
and'others that will become apparent as the nature of the invention is better understood the same consists in the novel form, combiiiation and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.
In the drawings, wherein like reference characters indicate corresponding parts throughout' the several views,
Figure 1 is a side elevational view of a wheel remover constructed in accordance with the present invention,
Figure 2 is an end elevational view of the device shown in Figure 1,
Figure 3 is a fragmentary detailed view partly in elevation and partly in section and illustrating the swiveled connection between the sections of one of the arms and the adjustable connection between the inner section of the arm and the cross-head of the device,
Figure 4 is an elevational view of a modified form of outer pulling arm section,
Figure 5 is a perspective view of one of the retaining bushings of the swivel connection,
FULLER.
1923. ySerial N0. 652,045.
. Figure 6 is a View similar to Figure t of still another form of outer pulling arm section.
Referring more in detail to the drawings, the invention embodies a crosshead or bar 5 which is formed of suliicient size as to withstand the use to which it is put, the form of the bar shown being preferable and in the nature of a flat piece of metal or the like 'having a ycentral transverse threaded opening 6 for reception of the usual thrust screw 7, the outer end of this screw being formed with an angular head 8 to be engaged by a suitable handle or wrench for facilitating rotation of the same, and the inner end of the screw being pointed or the like as at 9 for proper engagement with the end of the axle or other member which carries the device to be removed. The bar 5 is provided with longitudinal slots extending inwardly from the ends thereof so as to provide the ends in the form of spaced parallel legs 10. lEach pair of legs is provided with a longitudinally aligned series of transversely aligned openings 11, and the pulling arms 12 embody inner sections 13 having flattened inner ends also provided with a series of longitudinally aligned openings 14 adapted to be selectively aligned with desired pairs of the openings 11 and to then receive a removable pin 15 whereby the arms are attached to the orosshead 5. Y,
By means of this construction the pulling arms 12 may be adjusted in a convenient manner toward and away from each other as well as in a direction parallel with the longitudinal aXis of the screw 7, which adjustmcnts are essential in accommodating the tool to different kinds of work.
The outer ends of the arm sections 13 are formed with longitudinal internally threaded sockets 16, and the arms 12 also include outer arm sections 17 having their inner ends reduced to provide necks 18 with their free ends enlarged to provide heads 19, the outer ends of the arm sections 17 being of hooked formation as at 20 to engage the article to be removed. The heads 19 are of circular form and adapted to revolubly fit in the inner ends of the sockets 16, a split bushing 21 being placed upon the neck or stem 18 behind the head 19 and removably threaded into the sockets 16 for effectively attaching the arm sections to each other whereby the outer arm sections are freely' movable about their longitudinal axes. The bushings formed of longitudinal half sections as shown at 21 in Figure 5 so that these bushings may be engaged with or disengaged from the necks 1S. of the arm sections 17 when desired. For facilitating threading of the bushings 21 into or out of the sockets 16, the outer ends of these bushings are provided with knurled flanges 22, and the arms 10 are preferably provided with transverse pins 23 at the outer sides of the arm sections 13 for preventing swinging movement of the arms toward each other when the operator is placing the puller upon the article to be removed.
In Figure 1 the arm sections 17 are of the preferred form used for pulling or removing the rear wheels of automobiles, and the form of the ends 2O of these sections is such that, if it is not possible to obtain a hold on the brake drum, the sections 17 may be turned as indicated by dotted lines in Figure 2 to engage a spoke of the wheel.
- Modified forms of the arm sections 17 are respectively shown at 17a in Figure 4, 17b in Figure 6, and 173 in Figure 7. The arm sections 17a and 17b are particularly useful for small gears, such as cam and timing gears on automobiles and the like, while the arm section 17c is used for heavy work such as fly wheels, etc. The arm ctions 17 a, 17b and 17c are shorter than the arm sections 17 and have different forms of hook-shaped ends 20, of a smaller size, for these uses. Otherwise, the construction of the arm sections 17a, 17'D and 17 C are similar to the arm sections ,17, each of the same embodying the reduced neck 18 having an enlarged head 19 `upon the free end thereof adapted to rotatably fit in the sockets 16 of the sections 13 with which the arm sections 17 are employed. The different forms of outer arm sections are provided in which are thus capable of being interchangeable employed in the sockets 16 of the sections 13 to thereby meet the needs of any machine shop.
From the above description it will be seen that the present device has a very large scope of usefulness, the outer pulling arm sections 21 are preferably being capable of being turned to any desired angle without removing the same from the cross-head, this insures capability of positioning the arm as required in accordance with the various kinds of work to behandled, and the outer arms will automatically turn to accommodate themselves to the proper pulling angle when the pressure is exerted on the screw 7, thereby giving a greater pulling power. By employing interchange able outer pulling arm sections, the necessity ofhaving a set of complete pullers for each of the uses mentioned, is avoided and the expense thereby minimized.
While the invention has been above noted as primarily adapted for the ren'ioval of gears, wheels and the like, it is obvious that the same can be employed as a three-point jack used in bending pipes, straightening crank shafts, cam shafts, etc.
From the foregoing description it is believed that the construction and operation as well as the advantages of the invention will be readily understood and appreciated by those skilled in the art. i
Minor changes may be made without departing from the spirit and scope of the invention as claimed.
I/Vhat I claim as new is:
1. In a wheel puller or the like, a pulling arm including an inner arm section having one end formed for connection with athrust screw carrying cross-head and having its other end provided with an interiorly threaded socket, an outer pulling arm work engaging section having its inner end ree duced to provide a neck with a head upon the free inner end portion thereof adapted for revoluble lit within said socket, and a split bushing threaded in the socket and surrounding the neck forwardly of the head for detachably retaining` the outer arm section connected to the inner arm section for free turning movement relative to the latter.
2. A three-point jack comprising a crosshead provided with a central thrust screw and end pulling arms, said pulling arms embodying 'inner sections and outer sections detachably connected for free rotation relative to each other about their longitudinal axes.
In testimony whereof IafliX my signature.
SAMUEL CHINN.
