May 31, 1932. c. SCHEUNER QUICK DETACHABLE HANDLE FOR TOOLS Filed July 1, 1931 fn ATTORN Y Patented May 31, 1932 CHARLES SCHEUNER, OF CHICAGO, ILLINOIS QUICK DETACHABLE HANDLE FOR TO OLS Application filed July 1, 1931. Serial No. 548,241.
UNITED STATES PATENT OFFICE The invention has relation to detachable handles for tools, having for an object to provide certain improvements therein including a self contained handle wherein there are no detachable parts to become lost or mislaid. Other objects and advantages will hereinafter appear.
tudinally channeled at 2 to receive a longitudinally movable spring strip 3.
At one end this spring strip is provided with spring jaws 4, 4, opposed to each other, the inner ends of said aws being brazed or otherwise forming part of the spring strip at 5, and being normally received within a recess or channel enlargement 6, of one end of said handle, in such manner that the outer ends of the lateral walls of said recess bear against the inner ends of said spring jaws to maintain said jaws closed together, the closing of the jaws together being brought about during the longitudinal movement of the spring strip 3 in one direction through engagement of the lateral walls of said recess with said spring jaws.
In the longitudinal movement of the spring strip 3 in the opposite direction, the spring jaws 4, 4, are moved withou'tsaid recess 6, and spring apart as shown in Figure 3.
The knife, file, or other tool 7, is provided with perforations 8 in its tang 9, said tang being received between said spring jaws 4, 4, in which position, its said perforations are engaged by pins 10, of one of said jaws 4, said pins being long enough to extend past the perforations of said tang into engagement with aligned perforations 8' of the opposed jaw. The spring jaws 4, 4, are spaced apart I position the perforations 8 of the tang relative to the perforations 8 and pins 10 of the jaws, so that when thejaws are closed towards each other said pins will accurately engage said perforations. This squared end engagement of the parts also braces the tool against strain.
In the movement of the strip 3 in one direction, the inner ends of the spring jaws 4, 4, which in spread or open position are located without the recess or channel enlargement 6 of the handle, as shown in Figure 3, are brought closely within the same, as in Figure 1, and the inner of the perforations 8, 8', of one jaw and of the tool tang and the inner of the pins- 10 engaging said perforations are also brought within said recess, being covered and protected by the side walls of said recess to thereby hold said pins securely engaged with said perforations and to brace the tool against strain. The tool is provided with squared transverse shoulders 21 and the spring jaws have squared freev ends 22, engaging said shoulders in closed position of said jaws to further brace the tool against strain.
Thus, when the spring strip 3 is moved in one direction, the opposed jaws 4, 4, spring apart, and release said tang, inasmuch as the pins 10 of one of the jaws will bebrought out of engagement with the perforations 8 of the other jaw and with the tang perforations 8. In order that this release may be facilitated, the pins 10 are beveled at their outer ends at'll.
In the movement of the spring strip 3 to close the jaws 4, 4, together to grip the tang, at the end of the movement, a lateral pin or catch 12 of the other end of said strip is engaged with the outer extremity 13 of one side of the handle 1, to hold the jaws 4, 4, closed together, the inherent elasticity of the spring strip holding said catch engagement.
1 In releasing the tool, the lower end of the spring strip 3 is moved laterally, to move the catch 12 from the handle end 13, after which the spring strip 3 is moved longitudinally of the channeled handle to release the jaws 4, 4, as stated, a loop 14 at said lower end of the spring strip 3 during this longitudinal movement of the strip, entering a recess 15 of the other end of the handle. The longitudinal movement of the spring strip to close the jaws 4, 4, together is limited by engagement of lateral squared shoulders 4', 4', of lateral extensions of said jaws against the adjacent squared end of the handle, as shown in Figure 2. This squared engagement of the parts further braces the tool against strain. As shown, the recess 15 is formed by bending one side of the lower end portion of the handle 1 outwardly as at 16.
In practice, the pins 10 have each a reduced threaded stem 17, engaging the perforation of the related jaw 4, a nut 18, being threaded upon said stem and seated in a lateral recess of said jaw.
I claim z-- 1. In a detachable handle for tools, where-' in the tool tang is provided with a perforation, and the tool handle has a longitudinal channel, and a longitudinal strip has sliding engagement with said channel and is provided at one end thereof with opposed spring jaws one of which has a perforation and other of which is provided with a pin engaging the perforations of said tang and of the first named jaw; said jaws having the inner end portions and the perforation and the pin thereof located closely within and covered and protected by the side walls of said channel to hold said pin securely engaged with said perforations and to brace the tool against strain.
2. In a detachable handle for tools, where'- in the tool tang is provided with a perforation, and the tool handle has a longitudinal channel, and a longitudinal strip has sliding engagement with said channel and is provided at one end with opposed spring jaws one of which has a erforation and the other of which is provided with a pin engaging the perforations of said tang and of the first named jaw; said jaws having theinner end portions and the perforation and the pin thereof located closely within and covered and protected by the side walls of said channel, and said strip having a squared end located at the root of and between said jaws and the tool tang having a squared free end engaging said strip end to accurately position the tang perforation relative to the pin and aw perforation prior to engagement.
3. In a detachable handle for tools; wherein the tool tang is provided with a perforation, and the tool channel, and a longitudinal strip has sliding engagement with said channel and is provided at one end thereof with opposed spring aws one of which has a perforation and the handle has a longitudinal other of which has a pin engaging the perforations of said tang and of the first named jaw; said jaws having the inner end portions and the perforation and the pin thereof located closely within and covered and protected by the side walls of said channel, and said strip having a squared end located at the root of and between said jaws and the tool tang having a squared free end portion engaging said strip end, said jaws having squared free ends and said tang having squared transverse shoulders engaged thereby to brace the tool against strain.
In testimony whereof I afiix my signature.
CHARLES SCHEUNER.
