Specification of Letters Patent.
Patented July 23, 1907.
Application filed March 23, 1907; Serial No. 364,089.
To all whom it may concern:
Be -it known that I, Vro'ron HANSEN, a citizen of the United States of America, residing at Sparks, in the I county of'Washoe and State of Nevada, have invented new and useful Improvements in Wrenches, of which the following is a specification. V v
This invention relates to improvements in wrenches of the socket type designed to be operated by hand or power, and its object is to provide a wrench especially adapted for turning stay bolts in steam boilers and gripping and handling other similar articles, the construction being such as to secure a firm grip upon the article to be manipulated without injury thereto.
The invention is illustrated in the accompanying.
drawing, in which:
Figure 1 is a sectional elevation of the improved wrench. Fig. 2 is a bottom plan view of the same. Fig. 3 is a horizontal cross section through the wrench head. Fig. 4 is a detail view of the gripping jaw. Fig. 5 is a detail view of the retaining screw.
Referring to the drawing, 1 designates the shank of the wrench which is provided at one end with a frustoconical head 2 and at its opposite end with a stem or tang 3, which'is polygonal in form for connection with" a tool. brace or. motor driving appliance of any kind.
The head 2 is formed with a receiving socket 4 adapted to be fitted over an end of the article tolbe gripped and turned. The wall of this socket is cored out at one side to form a dovetailed longitudinal groove or ecess '5. The groove 5 is adapted to receive a taperedovetailed jaw 6, provided with a longitudinal series .(if parallel gripping spurs or teeth 7-, which are beveled and inclined in one direction to firmly engage the inserted surface of the article to be turned. 1 i
The jaw is formed with an opening 8 to receive aretaining pin or dowel 9 on the end of a. securing screw 10, working in a transverse threaded bore 11 in one of the side walls of the socket, said screw being provided at the point of junction of its threaded body with a shoulderl2 bearing against the rear side of the jaw and forcing its beveled surfaces against the undercut side walls of the groove 51 The pin 9 holds the jaw from outward movement, while the clamping action of the shoulder 12 relieves the pin from overstrain and assists the same in fastening the jaw from movement.
In use, the head 2 is placed over the end of the bolt or article to be turned, which enters the recess 4, so that upon turning the wrench the article will be gripped by the teeth of the jaw 6, thus firmly engaging the wrench therewith; Owing to the form and con.- struction of the jaw the teeth will grip the article without sliding thereon and, consequently, without mutilating the same, By the use of jaws with teeth inclining in opposite directions the bolts may be turned either in or out, and by simply partially retracting'the screw to withdraw the pin, the jaw may be removed and another substituted in its place and any one of a number ofinterchangeable jaws of the construction shown may be employed to suitv different conditions of service.
Having, thus described the invention, what is claimed as new, is:
A-wrench having a receiving socket and a tapered, longitudinal dovetalled groove formed in the side and opening through the base thereofand'havlng an inner stop wall, and provided with a transverse threaded opening communicating with said groove, a tapered dovetailed jaw adapted to flt within the groove and limited in inward movement by said stop wall and provided with a'transverse opening to coincide wlth'sald threaded opening, and
ascrew arranged at right angles to the jaw and working.
in said threaded opening and having a reduced smoothsurfaced end forming a pin to engage'the opening in the jaw to retain the same in position, said screw being also formed wlth a shoulder to clamp the jaw against the side walls of the groove. I
. In testimony whereof, I afllx my signature in presence of two witnesses vrc'ron HANSEN.
Witnesses G. ED C. Trmvnns, S. G. Bon'rrnans.
