BERT R. SPAULDING, OF BUFFALO, NEW YORK, ASSIGNOR OF ONE-HALFTO STEPHEN E.
SPAULDING, OF SPRINGVILLE, NEW YORK.
BIT-BRACE WRENCH.
Specification of Letters Patent.
PatentedSept. 1, 1908. l
Application filed. October 3, 1907. Serial No. 395,729.
To all whom it may concern:
Be it known that I, BERT R. SPAULDING, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Bit-Brace Wrenches, of which the following is a speciiication.
This invention relates more particularly to the class of wrenches which are provided with a shank adapted to be inserted in the socket of an ordinary bit-brace and which are used for tightening or loosening nuts and bolts and more especially those of vehicles and machinery of various kinds.
The object of my invention is the construction of a simple and convenient wrench of this type which can be cheaply manufactured.
In the accompanying drawings: Figure l is a side elevation of the wrench attached to a bit-brace. Fig. 2 is a sectional elevation of the wrench, on an enlarged scale. Fig. 3 is an end view thereof. Fig. 4 is a transverse section in line 4 4, Fig. 2.
Similar letters of reference indicate corresponding parts throughout the several views.
A indicates the socket of a bit-brace of any ordinary construction, and B the shank of the improved wrench adapted to be inserted and clamped therein like a bit. This shank extends rearwardly from the central portion of a cross head or bar C to the ends of which are secured a pair of parallel forwardly-extending lugs or standards D. In the preferred constructiony shown in the drawings, the standards and the cross head are united b y a tongue-and-mortise joint and transverse rivets c.
F, F indicate a pair of parallel clamping jaws arranged between the standards D and slidable toward and from each other. These jaws extend forwardly some distance beyond the standards to enable them to enter a recess in which an ordinary wrench vcannot be conveniently inserted. In their shanks or inner portions the jaws are provided with openings g through which the cross head O passes, thus guiding the jaws on said head.
H indicates a rotary screw journaled at its ends in sockets i formed in the opposing inner faces of the standards D and held against endwise movement therein. This screw is provided centrally with a knurled collar L for turning it and on opposite sides thereof with right and left hand threads h1, h2 which engage with correspondingly screw-threaded openings jl, y'Z in the respective jaws F.
In the use of the wrench, upon turning the operating screw in one or the other direction the sliding jaws are simultaneously adjusted toward or from each other in an obvious manner.
By the relative arrangement of the cross head, the jaws and the adjusting screw herein shown, the jaws always maintain their' parallelism and are not liable to bind, and a very strong construction is at the same time obtained.
In assembling the parts, the aws are passed over opposite ends of the cross-head and engaged with the ends of the right and left hand screw and the socketed standards D are then engaged with the ends of the screw and secured to the cross head.
T claim as my invention l. In a wrench, the combination of a cross head, a pair of spaced standards projecting forwardly from said cross head, a pair of sliding jaws arranged between said standards and having their rear portions constructed to surround said cross head, whereby both the front and rear faces of the cross head form guides for the jaws, and a rotary right and left screw arranged on the front side of said cross head, held against endwise movement in said standards and engaging correspondingly threaded openings in the jaws, substantially as set forth.
2. In a wrench, the combination of a cross head, a pair of spaced standards projecting forwardly from said cross head, a pair of sliding aws arranged between said standards and having their rear portions constructed to surround said cross head, and a rotary right and left screw arranged on the front side of said cross head, held against endwise movelment in said standards and engaging said jaws, the aws being disconnected on the front side of said screw, leaving the space between them unobstructed from their front ends to the screw, substantially as set forth.
Vitness my hand this 1st day of October,
BERT R. SPAULDING. Witnesses:
O. F. GEYER, E. M. GRAHAM.
