SAFETY DEVICE FOR nrvn'rme Harman's.
Application filed February 21., 1924. Serial No. 684,430.
This invention relates to improvements in attachments for rivetinghammers and more particularly to an improved coupling means for attaching a riveting hammer, or rivet buster to the holder thereof. 7
The primary object of the inventionis to provide an improved means for holding the rivet set in position in the holder in. a manner that will permit the rivet set to be quickly released when desired, but which will firmly maintain the rivet set in position while it it is in use, and prevent the operator thereof from being injured.
Another object of the invention is to provide a deviceof this character which may be easily manipulated to permit the hammer to be removed from the holder when desired. g
Other objects of the invention will appear upon consideration of the following detail description and accompanying drawings, wherein Figure 1 is a longitudinal section through the device constructed in accordance with my invention, showing a riveting hammer mounted in operative position. I
Figure 2 is a similar view showing the rivet set being withdrawn, the locking means being released,
Figure 3 is a perspective view of one of the locking elements,
Figure t is a transverse section the line 4-4 of F igure 1,
Figure 5 is a'similar view taken on the line 55 of Figure 2, I
Figure 6 is a plan view of the end of the holder showing one ofthe locking pawls in position and retaining collar'removed.
Referring to the drawing byv numerals,
the body 1 of the hammer is provided with a cylindrical end as shown having a central longitudinal bore 2 which is adapted to receive the tool 3 comprising the shank 4t and head 5. The bore is adapted to snugly fit the shank 4 but in a manner so that the latter may be moved into and outot' engagement therewith when the tool is ,arranged in or out of position, as the case may The shank 4 is provided withdiametriof the body l after taken on opposite sides with longitudinally cally opposite slots adapted to receive lock ing pawls 7 which are equipped with lugs 8 adapted to fit slots 6 formed in the shank a when itisthrust into the bore 2. The locking pawls are arranged in recesses 9 in the body 1 at diametrically opposite sides thereof, and the recesses 9 are shaped and of sullicient size to permit inward and out-f ward movement of the locking pawls 7. I Surrounding the body 1 is a sleeve 10 adapted to be rotated and, as shown in Figs.
a and 5, thesleeve is provided with alongitudinal opening which is substantiallyellipti-cal in cross section, the major diameter of the ellipse being large enough to permit will be held in operative position as shown in F 1 Tolock the sleeve 10in operative position, a locking pin 11 is provided which is pressed by a spring 12 whereby the end of the pin will engage an opening or recess 13 in the retaining collar 14 which is screw threadedly mounted upon the end placed. in position.
By giving a quarter turn to the sleeve 1O as indicated in Figs. 4 and'5 of the drawing I the pawls will be readily released or gaged as desired for releasing or retaining the tool in position inthe holder. In this manner any interchange of different types of tools may be made and the latter will be effectively held in operative position while the implement is in use. I lVhat is claimed is I In combination with a tool having a lindrical shank provided at diametrically isposed slots, a. holder comprising a cylinder, a sleeve positioned on said ,cylinderfor turnthe locking pawls 7 to move outwardly and the sleeve 10 has been" ing movement, said sleeve having one end portion of the opening therein elliptical 1n transverse section, a collar threaded upon one end of said cylinder for retaining the sleeve thereon, a 1ock1ng-p1n yshdably f mounted in the sleeve and engageahle with the collar for holding said sleeve against turning movement, said cylinder having slots formed therein, locking pawls arranged in said slots of said cylinder and held against the sides of the shank of the tool, and laterally disposed lugs on said pawls adapted to enter the slots in the shanle of the tool when the shorter diameter of the elliptical opening in the sleeve is disposed transversely of said lugs, the said lugs being adapted to swing out of the slots in the tool when the longitudinal diameter of the elliptical opening in the sleeve is disposed transversely of the lugs.
In testimony whereof, I have atiixed my signature.
