LUG-REMOVING DEVICE.
Application filed Dctcber 13, 1924. Serial No. 743,261.
To all whom it may concern:
Be itrknown that 1, MICHAEL Horrzsrniv,
citizen of the United States, residing at Los Angeles, county of Los Angeles, and State of California, have invented a certain new and useful Lugdlenioving Device, of which the following is a specification.
My invention relates to a means for removing members, elements, and other appurtenant parts from bodies to which they,
The object of the invention is to provide a simple tool for the purpose stated, by which the lugs or other riveted parts. may be pried while such bands are inposition in the hous ing; and vwliich may be conveniently inserted into the housing and operated from without;
Other objects will appear from the specifi cation following, in connection with the accompanying drawing, which illustrates a device for carrying outthe above objects, and in which,
Fig. 1 is a transverse section through the housing of a motor vehicle transn'iission;
showing the invention as actually used;
Fig. 2 is a sectional view showing the assembled parts of the device,
Fig. 3 is a fragmentary plan view; and
Fig. i is a plan detail of the lever used in connection with the device.
Referring to the drawing, it will be observed that the invention embodies generically a wedge or other element for prying li'iose an attached member, with a means for grip iiug or engaging the object to which such member is attached and a means for op erating the lever.
As showiii in the preferred form in the d rawi mg, the wedge n'ieinber 1. is a flat, sl ight- 'l y curving member having at one end thereof an acuminateor thinned edge 2, for facilitating the insertion and entry thereof between the lug 3 and band 4, to which the lug is riveted. The acuminate or thinned edge 2 is provided with an inwardly extended, substantially V-groove 5, the respective branches of which encompass or straddle the holding means, and the upper faces of which are preferably beveled, as at 6, to produce a prying or lifting action by a gradual wedging of the thinned edge 2 between the connected objects to be separated. end of said wedge member 1 is conjoined to the inclined face 7 of a thrust block or member 8, the connection of the wedge member with the block 8, being such that the former may have limited relative movement by which the wedge member may adjust itself to changes during the operation thereof. For the purpose of effecting an association of the wedge member with tie member 8 in the manner stated, pins 9 are provided in the member 8, such pins extending through elongated slots 10, in the other end of said wedge member 1, and provided with heads 11, to prevent dissociation of the lever from the member- In the drawing, 1 have shown a device of i specific use, is illustrative merely.
The block or member 8 aforementioned, is provided with a longitudinal smooth bore 13, for accommodating an externally threaded shank 14,-, carrying at one end thereof a means for engaging one of two conjoined objects that are to be separated. Such means may be a slotted device, as shown at 15, or any other that will positively and securely hold the engaged objects, while the wedge memberl is being operated to separate the same. I have referred tea slotted device merely because of the crmvenieut adapta tion to the lugs :3, but any device, coutrivarms or other means that engages mile of two or more conjoined objects to be se 'Jaratei'l, is comprehended within this disclosure.
The threaded sh ank 11 is held against rel ative rotation during the operation of the tool, by a stud or key 16, penetrating the block 8 at right angles to the bore 13 th rein and extending into a longitudinal. groove or key-way 17 in said shank. The block 8 movable longitudinally relative to said shank 1-4;, by hollow tubular body 18, provided with internal threads 19 arranged for co- The other i operation with the external threads of said shank 14-. The hollow tubular body is provided with a handle 20, for operating same.
Attention is called to the threads 1% of the shank 1 5i. The form of these threads is substantially that 01" a saw tooth, for the very important purpose of presenting to the thrust area practically a flat surface.
It will be noted that the thrust of the wedge member 1 occurs against a shoulder 21, on said block 8, and in'nnediately in the rear of said wedge member 1, the pins 9, re ferred to above, servingchiefly to hold said wedge member 1, associated, with said block, without sustaining any great amount of pressure.
In pactice, the slotted end 15, of the shank 1- is engaged with one of two or more objects to be separated. In the accompanyingillustration, this engagement oi the slotted end is shown with one 01? the lugs usually riveted to a transmission band. The wedge member 1, at the same time is introduced between the lug and the hand Thereupon the block 8 is caused to move by the manipulation of the body 18, such movement forcing the wedge member between the objects and eventually separating them, It will be seen that the greater the pressure exerted against the block, the greater will be the resistance oli'ered by the object engaging means.
What I claim, is
1. A device for removing lugs from transmission bands, comprising a shank having means for engaging: a lag, a member open able on said shank, an elongated wedge loosely connected to said i'nember, and means for operating said member on said shank to force said wedge between the lug and band.
2. A device for removing lugs irom transmission bands, comprising a shank formed with a slotted end for engagement with a lug, a member on said shank having an in clined bottom and a shoulder, a wedge loosely eonnectc l with the inclined bottom of said member and bearing against said shoulder, and means to operate said mem her to force .aid wedge between the lug and band.
3. A device for removing lugs from transmission bands, comprising a threaded shank having a slotted end for engaging a lug, a i'ncmber movable on said shank and having}; an inclined bottom terminating in a shoulder, a wedge means connecting said wedge to the inclined bottom of said member to have relative movement, and means for operating said IHQD'llJ'Ol' to force said wedge member between the lug and band.
4-. A device for removing lugs from transmission bands, comprisinga threaded shank having at one end a slotted means for engaging a lug, a carrier on said shank, a wedge connected to said carrier to have relative movement, and means to operate said carrier to force said wedge between the lug and band.
In testimony whereof. I have set my hand.
