CLAMP-DRAW GUN.
Application filed October 13, 1927. Serial No. 225,982.
This invention relates to a gun, motor or means for drawing wire or other clamp into secure engagement with spliced parts of garden hose or the like.
It is aimed to provide a novel tool capable of operation by means of compressed air or other power fluid.
It is further aimed to provide a novel construction wherein the cylinder is adapted to be secured to one end of the clamp and the piston rod of the device is adapted to be secured to the other end of the clamp.
The more specific objects and advantages will either be pointed out or become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.
In said drawing:
Figure 1 is a view in longitudinal central section illustrating the improved apparatus;
Figure 2 is a front elevation of the apparatus;
Figure 3 is a plan view illustrating the clamp as drawn about a spliced joint in accordance with my invention;
Figure 4 is a modified form of joint in connection with which the device is used, and
Figure 5 is a sectional view taken on the line 5-5 of Figure 4.
Referring specifically to the drawing, 10 designates a cylinder to which a base 11 is screwed at one end as at 12. At the other end, a bonnet 13 is applied which is clamped in place by a ring 14 screwed to the cylinder as at 15.
Slidable within the cylinder 10 is a suitable piston head 16 carried by a piston rod '17 which projects through an opening 18 in an end closure or cap 19 threaded as at 20 to the outer end of the bonnet. An expansive coil spring 21 surrounds the rod 17 and bears at one end against the piston head 16 and at the other end against the inner end of the bonnet 13.
Compressed air or other power medium is adapted to be admitted to the cylinder 10 between the piston and base 11 as through a passageway 22 to which a valve 23 communicates and which controls the admission of compressed air or other power medium or fluid. A pet cook or outlet valve 24 is provided for the exhaust of power fluid from the c linder 10 and of course is normally close The device is used to draw a wire clamp such as that shown at 25 in Figures 3 and 4, around sect-ions of rubber or flexible garden hose 26, being spliced together and which ends are disposed over a short length ofpipe or the like 27 The clamp 25 is generally of U-shape and is a wire strand whose terminals 28 are passed through the loop formed by the device and bear against the bridge 29 of the clamp. Such bridge 29 is adapted to be detachably engaged by the rod 17 and for instance by a hook 30 at the free end of such rod. The terminals 28 are adapted to be clamped to the cap 19. To this end, the cap is provided with spaced cars 31 between and to which a clamping lever 32 is pivoted by a pin at 33. Lever 32 may have a lug at 34 adapted to bind against the terminals 28 and the flexed portions thereof into a notch 35 in the cap 19, in line therewith. Appropriate pressure is applied to the lever 32 at the lug 34 through the operation of a screw 36, which is threaded through an opening 37 in such lever. The screw extends through a slot 39 in bonnet 13 and at its inner end bears on the rod 17 and in the operation of the parts is adapted to be engaged by a cam bar 38 rigidly secured to the rod 17 In one form of the invention as in Figure 3, the clamp is drawn taut with portions thereof engaging adjoining ends of the sections 26 while in the form of Figure 4, a complete clamp is optionally used, with each of the sections 26.
In using the device, with the same connected as in Figure 1, and pet cock 24 closed, valve 23 is opened and compressed air is admitted to assagcway 22 into the cylinder 10, forcing t e cylinder 10 to the left, thus drawing the terminals 28, causing the clamp to tightly engage the hose sections 26 and bind them against the metal pipe end 27. During such relative movement of the piston and cylinder 10, the set screw 36 rides on the cam 38 which serves to effectively maintain the lever 32 in binding engagement with the terminals 28. In order to release the compressed air from the cylinder 10, the pet cook 24 is opened. The spring 21 then restores the cylinder and piston into normal relation so that the same will disengage bridge 29 and terminals 28, after which the excess terminals 28 may be removed by pincers or the like to form a completed joint as in Figures 4 and 5.
of operating fluid to the cylinder, said bonnet having a slot, a hook on said rod to engage a portion of a clamp ears on said cap, a lever pivoted to said ears and engageable with another portion of the clamp, a screw carried by the lever and extending through said slot into the bonnet for coacting engagement with said cam.
In testimony whereof I afiix my signature.
