WRENCH.
Specicaton of Letters Patent.
Application filed August 15, 1910.
Patented Sept. 19, `1911.
serial No. 577,135.
To all whom it may concern:
Be it known that I, WILLIAM BosTIoK, citizen of the United States, residing at North Braddock, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Wrenches, of which the following is a specication.
This invention relates to wrenches of the quick adjusting variety, and the principal object is to provide a quick adjusting wrench which may be readily adjusted and operated with one hand.
Another object is t-o provide a quick acting wrench of simple construction and at the same time as durable as the ordinary wrench.
With these and other objects in view which will be more fully set forth in the following specification, I have devised the wrench illustrated in the accompanying illustrations, in which,
Figure 1 is a side elevation of the wrench proper partially closed, Fig. 2 is a similar view showing the wrench opened wider, Fig. 3 is a side elevation of a modified form of the wrench, and Fig. 4 is a cross sectional view taken on the line A-A of Fig. 3.
In the accompanying drawings. and the specification, like characters of reference refer to likel parts throughout, and 1 indicates a wrench having either an integral or a separable handle 2, to this handle is secured the fixed member 3, having on one end a bearing socket 4 to which is pivoted a movable member 5. On the forward end of the Xed member 4 is an integral jaw 6 having a right angled extension 7 which forms a strap through which passes the movable member 5, to the outer end of which is a movable jaw 8. Resting on the top of the movable member 5 and slidable thereon is a locking wedge member 9 having a rack 10 on the upper inclined surface thereof.-
This wedge slides through the slot formed by the strap 7 which has teeth 11 on the upper part thereof.
Secured to one end of the wedge member is a strap 12 which straddles the two jaw members. In the movable jaw is a slot 13 parallel with said member. In this slot works a pin 14 which is secured to both sides of the strap 12. In the fixed jaw member is an inclined slot 15 in which operates a pin 16 which is also secured t-o both sides of thesaid strap. The incline of the slot 15 is equal to or parallel with the incline of the racked surface of the wedge member 9. The movable jaw member has a right angled extension 17 in which is a slot 18 through which passes the pin 19 lgvhich loosely connects the two jaw memers.
20 is a thumb rest by which the sliding wedge is ordinarily operated.
2l is a spring which holds the movable jaw normally in a raised position.
In operation the jaws of the wrench are separated as shown in Fig. 2, the wrench is held by the handle 2 and the aws placed over a nut, the thumb of the operator is placed on the inclined portion 2O of the sliding wedge member which is then forced forward as far as possible which closes the jaws over the nut, the teeth 11 on the strap 7 engages the rack 10 and holds it in a locked position and so tightly wedged that it will be impossible to give the slightest particle; the jaws at the same time being absolutely parallel to the sides of the nut, which they contact. The action of the pins 14 and 16 working in the slots 13 and 15 is to raise and lower the back end of the movable jaw member 5, thereby moving the entire jaw on a parallel line.
In Fig. 3 a modification is shown in which the sliding wedge member is secured at the rear end to a member 22 which is dovetailed to the grooves 23 and 23 of the movable aw member 24 by the inturned ends 26 and 26 thereof. The bottom of this member is joined at an angle parallel to the angle of the rack edge of the wedge member 9, and the socket bearing 27 has an inclined upper surface which is also parallel with the inoline of the wedge member and the member 22, by this arrangement the jaws of the wrench may always be kept parallel.
Other modifications may be made without departing from the spirit of the invention.
Having described my invention, I claim and desire to secure by Letters Patent 1. In a wrench a handle, jaw members parallel therewith, a sliding wedge adapted to hold said jaw members in relative position, means by which said jaw members are held in constant parallel relation, straps connecting said members, one of said members being movable, said wedge being seated upon said movable jaw, said wedge having serrations upon its inclined surface andg' means for engaging said serrations whereby said wedge will be held in fixed position.
2. In a wrench, a handle, jaw members parallel therewith, a sliding wedge adapted.
to hold said. jaw members in relative posit-ion, means bywhich said jaw members are held in constant parallel relation, straps conneeting said members, one of said members being movable, said wedge being seated upon saidl movable jaw, said wedge having serra- V tions upon its inclined surface, and.l a tooth on one ofV said straps adapted to engage said:
to hold said jaw members. in relative i position, means by which said jaw members a-re heldf in constant parallel relation, straps connecting said members, one ot said members being movable, saidv wedge being seated'A upon said movable jaw, said Wedge having` serrations uponv its inclined' surface, a tooth on said straps adapted to engage said serrat-ions, a spring adapted to hold said jaws normally apart, and inclined planes upon said members.
5,. In a wrench, a handle, jaw members :parallel therewith, a sliding wedge adapted to hold said jaw members in relative position, means by which said jaw members are held m consta-nt parallel relation, straps connecting said members, one of said members being movable, said wedge being seated upon said movable jaw, said wedge having serrations upon its inclined surface, a tooth onsaiidy straps adapted to engage said serrations, a spring adated to hold said jaws normally apart, an inclined planes upon said members, said planes. beingoppositely disposed.
6. A wrench having a fixed jaw member, and a movable jaw member, a strap on said fixed jaw member, said' strap straddling said movable jaw member, a sliding wedge, for locking said sliding jaw member, a strap secured to said wedge, pins on the strap secured to said wedge, said pins. operating in grooves in said jaw members for raising and lowering said movable jaw member in paralleli relation to said fixed j aw member.
In testimony whereof I affix my signature in presence of two witnesses` WILLIAM BOSTICK.
