GGLLAB-LRIEIGUVING T0011.
To all whom it may concern:
Be it known that I, Fnovo ANDREW MITCHELL; a citizen of the United States, residing at Portland, in the county of Multnomah, in the State of Oregon, have invented new and useful Improvements in (lollanRemoving Tools of which the following is a specification.
My invention relates to :1 collar removing tool and has as its principal object the pro vision of a continuous and effective device for quickly removing collars and wheels from shafts and'axles and the like.
A further object ofmy invention resides in the particular arrangement and comb-instion' of parts hereinefter described.
In the accompanying drawing Figure 1 is a top plan view of a device embodying my invention, parts being broken away.
Fig.2 is a vertical sectional view taken on V g the line A.A of Fig. 3.
of a modified form Fig. 3 is an clevational view of the device shown in Fig. 1, parts being broken away.
Fig. 4: is a side view of Fig. 3 looking from the'rightQ t- Fig. 5 is a bottom View of the device shown in Fig. 3.
Fig. 6 is a vertical sectional view through the center of tl'l'device shown in Fig. 1 when the same has been set for removing a collar from a shaft. i
Fig. 7 is an clevetional view of the same device in the position chown in Fig. ti.
Fig. 8 is a side view of the device taken.
from the right of Fig. 7.
Fig; 9 is a detail view, fpartly in section, showing the engisl' ment 0 one of the clamp ing jaws used withe collar to he removed.
Fig. 10 is a detail. View, partly in section,-
of device.
Fig. 11 is a detail'view, partly in. section, showing a modified engaging member such as is shown in Fig. 10, in engagement with the hub or collar to he removed.
Throughout the separate views. thesame part is designated by the same reference character.
Referring more particularly to the draw ings, 1 and 1" are twolongitudinal side pieces midway between which is a, threaded rod 2, the pieces 1 and 1' being held in proper relative position by being carried on the cross piece 3 which is enlarged and provided with an opening at the center sufii cient to permit the rod 2 to pass through Specification of Letters Patent Application filed November 9, 1916. Serial 13s. 3.30,5.

without touching. Above the cross-piece 3, the rod Qcarmes a second cross-piece 4with which it has threaded engagement, the cross piece 4 havmi g outwardly and downwardly inclined shou ders adapted to' engage with upwardly and inwardly inclined shoulders on, the heads 5 and 5? of the sidepicces 1 and 1, respectively. lonsequently, it will be seen that if the member '2 is pulled upwardly, the side pieces 1 and 1 will be thrown into vertical position by'the engage incnt between the shoulders on the member 4- and those on. the members 5 and, 5. The side pieces having been turned into the strictly vertical position or the position parallel to the rod 2, the set sore-vs? and 7 carried by the heads and 5 respectively, can he so sci to engage with the horizontal extensions 8 and 8 at opposite ends of the cross piece or yoke 4, so as to give n direct pull.
At the lower ends of the members i and 1' I provide engaging pieces such as 6 end 6, those shown in Figs. 1, 2, 3 and, 4L being in the form of jaws adepted to clamp a collar or the like beneath a flange such as 12 so that the pull may he transmitted. from the side pieces 1 the collar, the members 6 and 6' having studs 9 and 5% which project at right angles to the members 1 and 1 and are seated in holes in the members 1 and l as indicated in e.
The side pieces l and l" are shown heing pivotally rnoiiiited on the cross piece and also capable of adjustment thereon. by virtue of the fact that the cross piece 3 is provided with a number of holes at each end in which the pivot pins 11 and ii for the members 1 and 1, respectively, may he placed as desired, so as to vary the difierence between the members 1 and 1 and the central threaded rod 2.
In case the collar or Wheel hub to be re moved is not provided with a flan e such as 12 under which the jaws 8 and may fit, the hub or collar is preferably drilled so as to providesmall sockets or pockets to receive gmojcctions such as 13 on the engaging members 14 and 14.. Otherwise the arrangement shown in Figs. 10 and 11 is similar to that shown in the remaiz'iing figures.
In using my device, the side members 1 and l'niay be thrown so that the parts 6 and 6 or 14 and 14., as the case may be, engage with the collar or hub such as 10 or 15 and the rod 2 is'tm'ned so as to bring the yoke 4 up into engagement with the shoulders 5 and 5 so as to hold the jaw members agaii'lst the collar or hub. The
set screws 7 and 7 are then adjusted so that the yoke i will take a direct pull and not wedge against shoulder 5, whereupon the rod 2 turned so as to forceagainst the shaft or axle l6 and draw the collar or hub therefrom.
Having thus described my invention, 1 claim 1. A tool for removing collars and the like from sharlts and the like comprising in con'ibination, a cross-piece, a pair of side pieces pivoted to said cross-piece, a yoke, a rod intermediate said side pieces having threaded engagement with said yoke, means for transmitting stress from said yoke to said side-picces, and on for connecting said side pieces for engaging them with a collar or the like.
2, A tool for removing collars and the like from axles and the like comprising in combination, a pair of side pieces, a cross piece to which said side pieces are pivotally connected, a yoke, a threaded rod intermediate said side pieceshaving threaded engagement with said yoke, one end of each of said side pieces having a wedging engagement with said yoke whereby the said side pieces are spread at one end and brought together at the opposite end, means for transi'nitting stress from said yoke to said side pieces, and means for engaging said side pieces with a collar or the like.-
3. A tool for removing collars and the like from axles and the like comprising in con'ibination, a pair of side pieces, a crosspi'ece to which said side pieces arepivotally connected, a yoke, a threaded rod intermediate said side pieces having threaded engagement with said, yoke, one end of eachof said side pieces having a wedging engagement with said yoke whereby the said side pieces are spread at one end and brought together at said opposite ends, and
means for transmitting stress from said yoke to sa1d side pieces, means for en aging said side pieces wlth a collar or the ike,
said side pieces being adjustable on said cross-piece to'vary the distance between them.
4. A. tool for removing collars and the like from axles and the like comprising in combination, a pair of side pieces, a crosspiece to which said side pieces are pivotally connected, a yoke, a threaded rod intermediate said side pieces having threaded engagement with said yoke, one end of each said side pieces having a .wedging engagement with said yoke whereby said side pieces are spread at one end and brought together at the opposite end, means for transmltting stress from said yoke to said side pieces, and removable jaws on said side pieces for engaging them, with the 'collar or like.
5. In a tool for removing collars and the like in combination, a pair of pivotally mounted side pieces, means for applying a stress to said side pieces when in engagement with a member to be removed, and re movable jaws on said side pieces for engaging the side pieces with the member to be removed, said jaws having a pin and socket connection with said side pieces, the pin and said side connection extending at fight angle to the line of stress in said side pieces. ,7
6. In a tool for removing collars and the like in combination, a pair-of pivoted side pieces, means for placing stress on said 'side pieces, and engaging members on said side pieces for engaging the collar'or the like member to be removed, said members having a pin and socket connection with said side pieces, said pin and said connection extending at right angles to the line of stress in said side pieces. 7. In a tool for removing collars and the like in combination, a, cross' piece, side pieces adjustably pivoted to said crosspiece, a threaded rod intermediate said side pieces, a yoke having threaded engagement with said rod, said yoke having wedgin engagement with said side pieces tospre'a the side pieces at their pivot points, and an adjustable stress contact'member for transmitting the stress between, said yoke and the side pieces.
