SLIDING-JAW TOOL.
Application filed June 21, 1927.
This invention relates to new and useful improvements in sliding aw tools, of the nut and screw type wrench varlety, the invention aiming to provide a highly novel, simple and eiiicient tool in efiiciently operating tools, wherein the sliding jaw may be readily adjusted in a major manner with respect to the stationary jaw and wherein when the handle is grasped, the sliding jaw will be forced to further move inwardly towards the stationary jaw with the result that even though the maj or adjustment is not entirely accurate, a lirm gripping of the nut or pipe will be present, so as to negative any slippage of the tool from the pipe or nut.
In the drawings :wherein there is dis closed the most preferred embodiments of the present invention Figure l is a side elevation of a nut wrench equipped inaccordance with the invention.
Fig. 2 is a perspective of the secondary pivothandle of the tool for controlling the minor adjustments of the sliding jaw.
Fig. 3 is a'detail transverse sect-ion taken substantially upon the line 33 of Fig. 1.
Fig. f is a detail longitudinal section.
Fig. 5 is a similar view of a pipe wrench constructed in accordance with the invention.
F ig. 6 is a perspective of the sliding door shank employed in the type of the invention disclosed in ig. 5.
Fig. 7 is a perspective of a locking bail for the swinging handle, and
Fig. 8 is a fragmentary perspective of a modified form of sliding aw shank.
Now having particular reference to Figs. 1 to 4: inclusive, 5 designates the handle of the wrench preferably of heavy sheet metal, so bent intermediate its longitudinal edges to provide a handle of U-shape in cross section, see Fig. 3.
Suitably arranged upon one end of this handle 5 is a rigid wrench jaw 6, while arranged for sliding movement through the handle 5 at the jaw end thereof is the flattened shank 7 of a suitable sliding jaw 8, the inner end of this shank being greatly reduced and of rounded formation to provide an elongated pin 9 which is screw threaded as disclosed.
Pivotally disposed within the handle 5 at a point substantially intermediate the ends thereof as at 10 is a secondary handle 11, also of U-formation in cross section and of a less the handle 5.
Serial No. 200,482.
area than that of the handle 5, so that said pivot handle may be readily swung therein as indicated in Fig. 4.
As indicated by the dotted lines in Fig. 1 and the full lines in Figs. 2 and 1, the forward edge of this secondary handle 11 is of rounded contour so that it may freely pivot within Furthermore the sides of this secondary handle 11 are formed adjacent their forward edges with registering rounded openings at a point inwardly from the pivotal connection 10 for loosely receiving a solid ball 12, the surface of which projects through the opening, as clearly indicated in Fig. 3.
This ball is formed with a longitudinally extending threaded bore, for receiving the threaded pin 9 of the sliding aw shank, with the obvious result that when the ball is rotated, the sliding jaw 8 will be movedinwardly or outwardly, or towards or away from the stationary jaw 6.
The top wall of the secondary handle 11 terminates short of the forward edges of the side walls of said handle, so as to permit the handle 11 to swing upwardly upon its pivot.
The pivotal connection 10 is at a point he neath the ball receiving openings of the secondary handle 11, and at a predetermined point rearwardly of the forward end of said handle, so that as the handle swings upwardly, the stationary aw 8 will move outwardly, whereupon when the handle is swung inwardly towards the main wrench handle 5, a pull is occasioned upon the sliding jaw as will be readily obvious.
Pivotally attached to the rear end of the handle 5 is a locking bail 13 the portion between the sides of the handle 5 being bent inwardly as at 14- to provide a crank, upon which is disposed the knuckle 15 of a leaf spring 16, the ends of which extend forwardly beyond the knuckle for engagement with the center walls of the handles 5 and 11, obviously, for the purpose of normally swinging the secondary handle 11 in an outward direction as indicated in Fig. 1.
The rear end of the secondary handle 11 is formed upon its top side with a notch 17 for receiving the bail 13, when the same is moved into position thereover, thus affording a locking connection between the said main handle 5 and secondary handle 11. Furthermore by reason of the character of connection between the bail and the spring 16, said bail will be frictionally maintained in engagement with the secondary handle 11 to prevent the accidental releasing of the same.
Furthermore, when the bail 13 is swung rearwardly into the position as diselosed in Fig. 1, the spring 16 will also serve to frictionally bind the same against the end of the main handle 5 to prevent loose swinging of the same thereon.
In the form of the invention indicated in Fig. 5, there is also provided a handle 5 having upon one end a stationary jaw 6', similar in all respects to the handle and jaw 5 and 6 in the form of the invention previously described.
Also in this instance, there is provided a pivotally secondary handle 11 equipped with the small adjusting member 12. In this instance however, the sliding jaw 8 is of the pipe wrench variety, the same being of general L configuration, the elongated portion thereof extending within the handle 5' and being pivotally connected as at 18 to a block 19 slidable within said handle 5 which block is formed at its opposite end with an elongated pin 9, threaded through the ball adjusting nut 12.
Furthermore, the bottom edge of the elongated portion of the pipe wrench jaw 8 is equipped with a depending leaf spring 20 for the permanent wiping engagement with the center portion of the U-shaped handle 5' for obviously maintaining the said jaw 8 in substantially horizontal position with re spect to the handle.
However, by reason of the pivotal connection between this jaw and the sliding block 19, said jaw may be swung downwardly to increase the space between the opposed faces of the stationary jaw 6' and said sliding jaw, so that the work may be readily engaged therein.
In this form of the invention also, all major adjustments may be taken care of through reason of the adjusting ball 12. However, the closing of the secondary handle 11 will further cause the inward sliding movement of the sliding jaw 8 to firmly grasp the work.
In Fig. 8 there isdisclosed a pin 9" of modified construction that may be provided in lieu of the pin 9 and 9 previously described, this character of pin being of relatively flat shape, the upper and lower edges thereof being rounded and threaded as indicated.
When employing this character of pin, the adjustment ball may have mutilated threads within the bore thereof, so that when the threads of the bore are out of engagement with the threads of the pin, a rapid adjust ment of the jaw may be made, whereupon the threads of the adjustment ball are engaged with the threads of the pin to prevent further movement of the aws.
Having thus described my invention, what I claim as new is In combination, a wrench including a hollow handle having a stationary head upon one end thereof, and a movable head arranged upon a shank slidable through said handle and connected to a secondary handle pivotally secured within the main handle, whereby when the secondary handle is moved towards the main handle, said jaw will be drawn inwardly, a cantilever spring arranged between the handles and having a knuckle at the outer end of said handles, a bail pivoted to the main handle, and extending thereacross, and a crank portion formed upon the inner end of the bail and attached to said spring knuckle whereby the bail is frictionally maintained in position over the secondary handle or in position alongside the end of said main handle.
, In testimony whereof I aflix my signature.
