ADJUSTABLE SPANNER.
No. 582,288. Patented May 11,1897.
UNITED STATES PATENT OFFICE.
FREDERICK SCIIRADER, OF BRIDGEPORT, CONNECTICUT.
ADJUSTABLE SPANNER.
SPECIFICATION forming part of Letters Patent N 0. 582,238, dated May 11, 1897.
Application filed February 18, 1897. Serial No. 623,992. (No model.)
To all whom it flea/y concern:
Be it known that I, FREDERICK SCHRADER, a citizen of the United States, and a resident of the city of Bridgeport, State of Connecticut, have invented a certain new and Improved Adjustable S panner-VVrench,of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
The object of my invention is to provide a .new and improved form of wrench which may be adjusted for use in connection principally with circularlock-n uts of different diameters, thus avoiding the expense and inconvenience of employing a separate wrench for each size of nut.
A further object of the invention consists in so constructing the wrench that it may also be used as a nut-wrench and screw-driver, as more fully set forth hereinafter.
In the accompanying drawings, Figure 1 is a perspective View of a spanner-wrench constructed in accordance with my invention. Fig. 2 is an elevation of the same, illustrating its adjustment for use in connection with a lock-nut of small diameter. Fig. 3 is a similar View illustrating the use of the wrench in connection with a nut of large diameter, and Fig. 4 is a View illustrating a modification in which the nut is provided with a projecting v pin and the wrench with an orifice for the reception of said pin.
In spanner-wrenches as ordinarily constructed a separate wrench must be used for each size of nut, the end of the wrench having a pin-and-hole connection with the nut, and thence following the curvature of the nut, so that it may be in close contact with the latter to better effect its turning.
In a wrench constructed in accordance with my invention I provide an adjustable screw or block for contactwith the surface of the nut, so that a single wrench maybe used for nuts of various diameters.
Referring to the drawings, A represents the main body or handle portion of the wrench, the operating end of which is curved at C6 after the manner of the usual construction of spanner-wrench and arranged to operate with a nut of the largest diameter. At or near the curved end of the wrench is a pin b, which in operation engages an orifice or slot m in the nut X, or, as shown in Fig. 4, the nut may be provided with a projecting pin 00 and the wrench with an opening I). The extreme end of the curved portion a is flattened to form a screw-driver c, and the opposite end of the main body of the wrench is made in the form of a wrench d for use in connection with faceted nuts of the ordinary construction. At about the point where the curved portion a merges into the main body A there is formed an enlargement provided with a threaded opening, through which extends a thumbscrew E, as shown.
In operation the pin-and-hole connection with the nut is first made, and then the screw E is turned until its inner end is forced into contact with the periphery of the nut and forms a second contact or bearing point,which makes the wrench just as effective as though its curved surface were in intimate contact with a large portion of the periphery of the nut.
It will be seen that the wrench can be applied to nuts of large or small diameters within a reasonable limit, although by increasing the length of the screw in the construction shown the capacity of the wrench may be increased to any desired extent.
The screw-driver c is of a form convenient for many uses, and the handle A being at about a right angle thereto gives it the additional advantage of the leverage to be gained in use. I
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
1. A spanner-wrench comprising a main body portion and a curved end constructed to make a pin-and-hole connection with the nut, and a second contact or bearing adj ustable toward and from the periphery of the nut.
2. The combination in a spanner-wrench of the main portion, A, having a curved end, a, a pin, 17, on said curved end, and a screw, E, adapted to a threaded orifice in the main portion, A, substantially as specified.
3. The combination of the main portion, A, In Witness whereof I have hereunto set my having a curved end, a, a screw-driver, 0, hand this 10th day of February, A. D. 1897. formed at the curved end, a nut-wrench, d, FREDERICK SCHRADER at the opposite end, a pin, 11, projecting from 5 the curved end, and a screw, E, adapted to an Witnesses:
orifice in the main portion, A, substantially F. H. SPENCER,
as specified.
