Description

June 24, 1930. F. IZZO 1,766,296
SAFETY DEVICE FOR PNEUMATIC HAMMERS Filed July 13. 1927 Frau L71 I220 INVENTOR ATTORNEY Patented June 24, 1930 NETE FRANK IZZO, F HUNTINGTON, WEST VIRGINIA SAFETY DEVICE FOR PNEUMATIC HAMMERS Application filed July 13, 1927. Serial No. 205,465.
This invention relates to a safety device for pneumatic hammers, the general object of the invention being to provide a sleeve which is connected with the end of the barrel of the hammer and encloses the chuck bushing and holds the same in place, thus preventing the bushing from being thrown from the hammer.
Another object of the invention isto so form the sleeve that the tool can be readily placed in the bushing and removed therefrom without interference on the part of the sleeve.
Another object of the invention is to so form the sleeve that it can be easily placed on the barrel and removed therefrom.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, i1-
lustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a sectional View showing the invention in use.
Figure 2 is a section on line 22 of Figure 1.
Figure 3 is a perspective view of the sleeve.
As shown inthese views, the sleeve 1 is formed with a split 2 so that it can be expanded to permit its being placed on the hammer or removed therefrom, the sleeve being preferably made of spring metal. The sleeve is of tapered shape, with an inwardly extending flange 8 at its large end and with a substantially cylindrical portion 4 at its small end. The flange is adapted to engage the annular groove 5 formed in the barrel 6 of the pneumatic hammer and the sleeve is rotatably mounted on the barrel. The tapered end 7 of the barrel, when placed against the flange, will force the sleeve open so that the flange will slip into the groove 5. The sleeve encloses the chuck bushing and holds the same in place so that there is no danger of the chuck bushing being thrown from the hammer when this device is being used on the hammer. The cylindrical part 4 of the sleeve forms a bushing at the outer end of the device for the tool 8, but said part permits free movement of the tool.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall with in the scope of the appended claims.
hat I claim is 1. A safety device for a pneumatic hammer comprising a split spring metal sleeve tapering from its inner to its outer end, the sleeve being of considerable length and forming a hand hold, a chuck bushing having a part fitting in the sleeve whereby the sleeve holds the bushing in place, a cylindrical part at the small end of the sleeve for slidingly receiving the tool of the hammer and a flange at the large end of the sleeve for rotatably engaging a groove adj acent the end of the barrel of the hammer.
2. A safety device for a pneumatic hammer comprising a sleeve, means for connecting the sleeve to the end of the barrel of the hammer, a chuck bushing having a part fitting in the sleeve whereby the sleeve will hold said chuck bushing in the end of the barrel and a part on the sleeve for slidingly receiving the tool of the hammer.
In testimony whereof I aiiix my signature.
' FRANK IZZO.
