SPECIFICATION forming part of Letters Patent No. $81,97 dated December 8, 1885.
Application filed December 13, 1884, Serial No. 150,980, (X0 model. I
1'0 all whom it may concern:
Beitknown that I, OARLKABISGH, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to an improvement in slidingjaw wrenches; and it consists in the combination, with a wrench having a sliding jaw and grooved or recessed bar, of a sliding rack which has its upper end beveled and with which the jaw. engages, and a means for moving both rack and jaw after the jaw has been adjusted by hand, as will be more fully described hereinafter.
The object of my invention is to provide a wrench with a means for tightening the jaw upon the object to which it is applied after the jaw has been moved by hand, so as to bring it in contact with the object and thus prevent the jaw from slipping on the object and bruising its corners or edges, and thus spoiling the finish and beauty of the workmanship.
- Figure l is a side elevation of a wrench embodying my invention, partly in section. Fig. 2 is a detail view of the sliding rack.
A represents a wrench of ordinary construction having a sliding jaw, B. The in ner edge of the bar 0 of the wrench, instead of having a rack formed upon it in the usual manner, here hasia longitudinal groove, D, formed in it, which groove has its upper end made inclined, as shown, for the purpose of acting as a wedge upon the sliding rack E which is placed in the groove. This rack E, fits snugly in the groove and has an endwise movement therein, and has its upper end beveled away, so as to correspond to the bevel at the upper end of the groove. In the lower end of the rack is made a transverse groove, F, in which the thread of the adj ustingscrew G catches, for the purpose of moving the rack endwise when the screw is turned. Inside of the sliding jaw are formed a number. of teeth, H, which are made to engage with the teeth of the rack by nieims of a suitable spring, I, which. is placed inside of the lower end of the jaw. By pressing against the projection J on the lower outside corner of the jaw the jaw is disengaged from the rack, and can then be moved freely back and forth in the usual manner.
One great trouble with sliding jaw wrenches is that after the jaw has been moved up in contact with the object by the hand the jaw does not bite into the object with sufiicient force to prevent it from slipping off from the object and thus bruising its corners or edges, which is very objectionable where there is fine workmanship. To prevent this slipping, the slidingjaw and its adjusting-screw is pro vided. After the jaw is moved by hand up against the object, the screw is moved or turned for the purpose of forcing the rack upward in its groove. As the jaw engages with this rack and moves with it, it wiil readily be seen that the jaw can be forced against the object with any desired degree of force, and thus compel it to bite into the object in the same manner as in the old screwjaw wrench.
the construction here shown there is combined in one wrench all of the advantages of the sliding-jaw and a screw wrench.
I am aware that a sliding ratchet-rod has heretofore been pivoted to one half of the handle, so as to move when said half of the handle is closed or opened, and that a lockingcam has been used in connection with said device, for the purpose of preventing the handle from opening when it is not desired to bring the sliding ratchet-rod into use. I am also aware that a sliding ratchet-rod has been used and moved by revolving a portion of the handle, and these I disclaim. My invention differs from these devices in placing the sliding ratchet-rod in a groove and beveling the ends of both rack and groove, so that when the ratchet-rod is moved endwise it is forced outward,-so as to loci; the jaw in place.
Having thus described my invention, I claim In a sliding-jaw wrench, the combination In testimony whereof Iaffix my signature in 10 0f the recessed bar 0, the rack D, which is presence of two Witnesses. placed in the recess in the bar and which has its upper end beveled to correspond to the CARL KABISOH. shape of the upper end of the recess, the
sliding jaw, and a cam for moving the rack \Vitnesses:
