IRA CHURCH, OF MUSKEGON, MICEIGAN, .QrSSIGrNQIB. 0F ENE-HALF T0 LOTTIE SANFORD, OF REED CITY, MICHIGLN- wnnncn.
Application filed March 13, 1919.
To all whom it may concern:
Be it I. iown that 1, Ina. CHURCH, a citizen of the United States, residing at Muskegon, in the county of hlluskegon and State of Michigan, have invented new and useful Improvements in Wrenches, of which the following is a specification.
The present invention relates to wrenches and its object is generally to provide an improved implement of that character; and more particularly, to provide a wrench whose parts may be so adjusted as to turn the work-as a nut or a boltreadil and very quickly, and when greater resistance to the action of the wrench encountered, whose parts may be otherwise so adjusted as to turn the work with more power.
T his and any other objects hereinafter appearing are attained. by, and the invention finds preferable embodiment in, the structure hereinafter described and illustrated by the accompanying drawings, in which Figure 1 is a top plan view oi. a wrench;
Fig. 2 is a side view of the same, certain parts being broken away;
Fig. 3 is a sectional view of parts taken on a plane corresponding to line 3-3 of Fig. 2;
F 4 is a detail view, partly in longitudinal central section, of the work-engaging member of the wrench; and.
Figs. 5 and 6' are views in perspective of certain attachable parts thereof.
In the embodiment of the invention chosen for illustration by the drawings and for detailed description in the body of this specification, the wrench has a body portion 1 which carries a rotatable work-engaging member 2 having the spindle 3 which may be secured in its rotary bearing 4 in the body as by a pin 5 engaging the annular groove 6 in the spindle, as shown in Fig. 3.
The body carries also a handle 7 in non rotatable and splined relation to its spindle 8, the radial pin 9 of the handle passing through the elongated slot 10 oi the spindle, so that the handle may slide axially on the spindle but is non-turnable in relation to it. The handles spindle 8 rotates in the bearing 11 in the body.
Suitable means for rotating the work engaging member 2 by the rotation of the handle are provided, being in the construction shown, the bevel gear 12 in keyed relation to said member 2 and the meshing bevel gear 13 in keyed relation to the handles Specification of Letters Patent.
Patented Dec. 30, 1919.
Serial No. 282,417.
The socket 16 sunk in the end of the workengaging member 2 receives the work (as the bolt or nut) to be turned by the wrench. Various devices may be adopted to fit the tool for nuts and bolts oi different sizes and shapes, as the attachments 17 shown in Fig. 5 and 18 shown in F 6, the first having a hexagonal socket 19 and the other a square socket 20, and each having a shank 21 adapted to lit in the socket 16 in the member 2 itself.
The wrench may be operated in the following manner: The work being inserted into the socket 16 (or into the socket 19 or 20 in case the device shown in Figs. 5 or 6 is employed), the handle 7 is slid toward the body 1 so as to move the clutch members 14, 15 into mutual engagement. Such eng ement holds the handle and thereby the ork-engaging member 2 against rotation through the meshing of the gears. Great power is exercised on the work in this adjustment, the length of the lever exerting the wrenching operation extending from the axis of the work-holding member to the grasped handle. A very tightly screwed down nut may be thus loosened and slowly turned. it the are through which the lever can swing be limited, the handle may be slid back to the position shown in Figs. 1 and 2, whereupon it may freely rotate while the wrench is swung to original position, the work remaining stationary during this movement: the handle being now slid to engage the clutch members, the wrench may be a. .ain swung, whereby the nut is given another loosening turn. l/l hen the nut is loosened sufliciently to turn comparatively easily, it may be readily and rapidly turned by holding the body or" the wrench stationary and rotating the handle, the clutch ir mbers being out of mutual engagement as shown in Figs. 1 and 2.
A. similar operation but reversed in order of procedure may be employed to turn the nut onto its bolt, and it will be seen that such operation may be conveniently car ied out, for the sockets will hold the nut withiii? out the necessity of using the hands for that purpose. This Wrench may be employed in many difficult positions, as in tightening or loosening the nuts Which hold the removable member of the box containing the crank pin of an automobile engine.
, The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction shown or described.
I claim 1. In a Wrench; a body; a rotatable Workengaging member carried by the body; a rotatable handle carried by the body; means for rotating said member by the rotation of the handle; means for holdingly engaging the handle directly and thereby locking the same and said member against rotation.
2. In a Wrench; a body having a clutchmember; a rotatable Work-engaging member carried by the body; a rotatable handle carried by the body, and having a clutch member, and being slidable axially into and out of the mutually engaging position of the clutch members; means for rotating the Work-engaging member by the rotation of the handle.
3. In a Wrench; a body having a clutchmember; a rotatable Work-engaging member carried by the body and having a gear; a rotatable handle carried by the body and having a gear meshing with the first-mentioned gear, a portion of the handle being in splined relation With the second-mentioned gear, and having a clutch member, and being slidable axially into and out of the mutually engaging position of the clutch members.
In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan,
this 8th day of March, 1919.
IRA CHURCH.
