UNITED STATES PATENT OFFICE BROKEN STUD REMOVER Raymond D. Schrader, Peoria, 111., assignor to V. Ray Van Wey, Pekin, Ill.
Application'March 24, 1944, Serial No. 527,983
1 Claim.
1 The present invention relates to new and useful improvements for removing broken studs from engine blocks and other places where the bolt or stud has been broken off below the surface of the block.
An important object of the present invention is to provide a screw-threaded member having a bit formation at its lower end and adapted to bite into the end of the broken stud and also to pro: vide means for rigidly supporting the screw threaded member While the same is engaging the broken stud and while the screw threaded member and stud are being removed.
A further object is to provide a device of this character of simple and practical construction,v
which is eflicient and reliable in performance, relatively inexpensive to manufacture, easy to operate and otherwise well adaptedfor the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout and in which Figure 1 is a fragmentary vertical sectional view of an engine block showing the tool in position for removing a broken studtherefrom and with parts of the tool shown in section,
Figure 2 is a top plan view,
Figure 3 is a perspective view of one of the spacing members, and
Figure 4 is an end elevational view of the broken stud removing member.
Referring now to the drawing in detail Wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention,
"the numeral 5 designates an engine block having the threaded tap or bolt holes 6 therein for securing the engine head (not shown) in position. The numeral 1 represents a stud or bolt which has been broken off in one of the bolt holes 6.
In carrying out my invention bolts 8 are threaded in the opening 6 at opposite sides of the broken stud I and positioned on the bolt and resting on the top of the engine-block are spacing spools 9 on which are supported the ends of a bridge member II], the bridge member having slots II in its end portion for adjustably receiving the bolts 8 and the bridge member is secured in a fixed position by the head of the bolt.
The bridge member is also formed with a central threaded opening l2 adapted to receive an internally and externally threaded sleeve l3 having a hexagonal head I4 at its upper end for re- Sleeve I3, and thereby augment the latters re-' .sistance to pressure.
The lower end of the screw I5 is formed with a head l8 adapted to bite into the top of the broken stud and to firmly engage the broken stud to remove the latter from the bolt holes 6 by a retracting movement of the sleeve 13.
It will also be understood that the screw l5 and sleeve l3 may be constructed of various sizes for use in extracting or removing various sized broken studs.
It will be apparent that the device of the present invention may be employed efiectively on any broken ofi stud regardless of the pitch of the threads thereon. Likewise, it is effective for the removal of any broken ofi. stud irrespective of whether such stud be flush with the plane surface of the block, or countersunk in the block, or with its end protruding from the block, and without requiring any prior drilling or like action thereon. Furthermore, it is obvious that this device may be used for the insertion of bolts or screws into position in blocks where the conventional means for such positioning can not be employed.
It is believed the details of construction, operation and advantages of the device will be readily understood Ifrom'the foregoing without further detailed explanation.
Having thus described the invention, What I claim is: l
A broken stud remover comprising a bridge member, slots in each endof said bridge member, bolts positioned in said slots and adapted for securing said bridge member to the work at opposite sides of a broken stud to be removed from said work, removable spacing members on the bolts for spacing said bridge member above the work, a threaded opening in said bridge member intermediate its ends, an internally and ex- Mounted in
