Application filed February 28, 1921. Serial Ito. ,Mt.
To all whom it may concern:
Be it known that I, CLARENCE PAGE, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented certain new and useful Improvements in Looking Means for Impact Tools, of which the following is a specification.
My invention has relation to means for locking together certain parts of impact tools such as the cylinder and handle socket of a pneumatic hammer, which parts are liable to work loose due to vibration. The object of my invention is to provide simple and efiicient locking; means for this purpose.
In the drawing ig. 1 is a section partly in elevation of the rear end of the hammer cylinder and the socket portion of a handle of a pneumatic hammer; Fig. 2 a section on the line 2-2 of Fig. 3; Fig. '3 a section on the line 33 of Fi 1, and Fig. 4: an end view of the bolt owing the eccentricity thereof.
Referrin to the embodiment of my invention as erein shown in connection with a pneumatic hammer the rear end of the her cylinder or barrel 1 fits within the socket 2 of the hammer handle. This socket is provided on its lower side with the two clamping In S 3-3 separated from each otherat their a jacent ends as shown at 4. A transverse hole extends throu h these lugs and also through the lower si e of the socket proper as well as through the adjacent side of the cylinder. This hole is adapted to receive the locking bolt 5 whose bodiyqrl portion is made of a peculiar contour as s own in the drawin and ada ted to cooperate with the irre Ian shape hole just referred to. This b0 t is made of two different diameters at its opposite ends and provided at its central part with an eccentric portion. As shown in Fig. 3 the larger diameter 6 of this bolt is at the head end thereof and the same fits in the hole 7 in the right hand lug 3. The smaller diameter portion 8 is at the screw threaded end of the bolt and the same passes through the hole 9 in the left hand lug 3. The eccentric portion 10 of the bolt lies between the portions 6 and 8 and the same is adapted to cooperate with the groove 11 in the side of the cylinder 1, it being understood that the hole through the left hand lug 3 is enlarged as shown at 12 to accommodate this eccentric portion 10.
As shown in Fig. 1 the cylinder and handle socket have a tapered connection, that is, this cylinder and socket are correspondingly tapered so that the further the cylinder is forced into the socket the tighter the parts are connected. The purpose of the locking means constituting my invention is to not only hold the cylinder and socket in their connected position but by the same act to force the cylinder in the tightest possible connection with the socket, as made apparent by the following description of the manipulation of such locking means.
When the cylinder and socket are assembled with the groove 11 in register with the holes 7 and 9, the locking bolt is inserted with the cam or eccentric portion 10 in its lowermost position or at least in the position shown in Fig. 2. The bolt isthereupon turned with the result that the eccentric portion 10 will bear against the groove 9 and tend to force the cylinder 1 inwardly as far as it will go so that the cylinder will be tightened in the socket and will be effectually locked thereto.
I claim:
In a neumatic hammer, in combination, a cylin er havin a tapered end, a handle having a tapere socket receiving the tapered end of said cylinder, said handle socket having aligned holes of diflerent diameters and said cylinder a groove registering with said holes, and means for tightening and locking said cylinder in said handle socket comprising a bolt having ends fittin said ali ed holes and an intermediate 0 set portion coo crating with said groove to force the cylin er into the socket.
CLARENCE PAGE.
