Referring to Figures 2 and 3, the end of the Of the accompanying drawing: shaft II at I9 is formed with a transverse bore Figure 1 is a top plan view of a stud remover as at 28 and the wheel I! is formed with transembodying the invention. verse notches 2|, 2| aligned with the bore 20 and Figure 2 is a bottom plan View thereof. being curved or tapered as indicated at 22, 22, Figure 3 is a section on line 3-3 of Figure 1. so that a piece of comparatively stiff, semi-flex- Figure 4 is a section on line 4 i of Figure 1, ible wire 23 may be utilized as a key for securing ow the dev e as u d for r moving a broken the wheel I! on the shaft I I, this wire being enstud as from an engine block. gaged in the bore 20 from one side thereof Referring to the drawing, the numeral I0 indithrough a notch 2| and being driven through and cates a cylindrical block in which is journalled a into engagement with the other notch 2!, the shaft Ii arranged at one side of the block and curved or tapered portions 22 of which flex wire which may be formed with a suitable socket eleto some extent to guide it through the aperture ment E2 to be turned by a wrench I 3 indicated in and also to hold it tightly in place. This Wire, dotted lines in Figure 4, the socket element I2 exas will be obvious, can easily be driven out of the tending above the block It. The block I0 is bore 23 by pressing a suitable tool against one formed with two apertures or bores I4, I5, extendend of the wire to remove and replace the wheel ing through the same and the inside of which may IT. This key permits a flush gripping wheel be knurled or roughened as indicated. These construction so that the tool is capable of use as indicated in Figure 4 on even the shortest of studs or dowels.

In use, the tool will be applied over the stud, as shown in Figure 4, with the stud engaged in whichever aperture I4 or I5 is the most effective depending on the diameter of the stud and then a wrench will be applied to the socket l2 and turned in a direction counter to that at which the stud was threaded into the block from which it is to be removed, which first turns the gripping wheel I1 so that its periphery H grips the stud between it and the opposite wall of an aperture l4 or [5. Continued rotation of the wrench l3 will turn the block I0 and the stud gripped therein and will thread the stud out of the socket in which it has been threaded.

Modifications of the invention may be resorted to Without departing from the spirit thereof or the scope of the appended claims.

What is claimed is:

1. A stud remover comprising a block formed with two adjacent apertures of different sizes for receiving studs of various sizes, the bottom of said block being recessed, a shaft rotatably extended through said block, said shaft having eccentrically secured on its bottom end a gripping wheel, the lower face of which is substantially flush with the bottom surface of the block, the spacings of said apertures with respect to the axis of said Wheel and the proportions of the wheel being such that the wheel may be turned on its. axis to grip studs or the like of various sizes in either of said apertures against portions of the walls thereof remote from the axis but permitting the wheel to be turned to a position in which it.

clears both apertures, and means on said shaft at the top of said block for rotating said shaft relative thereto to move said wheel to grip a stud in either of said apertures against said remote portions thereof and by continued rotation of the shaft to turn said block so as to turn a stud gripped in the block.

2. A stud remover comprising a block formed with two adjacent apertures of different sizes to provide relatively fixed jaws for receiving studs of various sizes, a shaft rotatably extended through said block, said shaft having eccentrically secured thereon a gripping wheel, the spacings of said apertures with respect to the axis of said gripping wheel and the proportions of the wheel being such that the wheel may be turned on its axis to grip studs or the like of various sizes in either of said apertures against portions of the walls thereof remote from the axis but permitting the wheel to be turned to a position in which it clears both apertures, and means on said shaft for rotating the same relative to said block to move said wheel to grip a stud in either of said apertures against said remote portions thereof, whereby continued rotation of the shaft will turn the block so as to turn a stud gripped therein.
