POWER-DRIVEN" CHUCK.
Specification of Letters Patent.
Patented July 8, 1919.
Application filed October 29, 1917. Serial No. 199,116.
To all whom it may concern:
Be it known that I, CHARLES O. DoMiNY, a citizen of the United States, residing at Lone Pine, in the county of Inyo, State of California, have invented certain new and useful Improvements in Power-Driven Chucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in chucks and particularly to power driven chucks.
One object of the present invention is to provide a power driven chuck which is adapted to operate only when the tool is pressed against the work.
Another object is to provide a novel con struction in a device of this character which can be quickly and easily taken apart for the purpose of cleaning and inserting and removing the tools.
Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.
In the drawing:
Figure 1 is an elevation of my improved power driven chuck the drive shaft being broken off.
Fig. 2 is a vertical longitudinal sectional view taken centrally through the chuck.
Fig. 3 is a perspective view of one of the clutch members removed from the casing.
Fig. 4; is a perspective view of the other clutch member removed from the casing.
Fig. 5 is a transverse sectional view taken on the line 55 of Fig. 2.
Referring particularly to the accompanying drawing 10 represents a tubular casing having one end formed with external threads for the engagement of the removable cap ll, which is formed with a central opening 12 in the end thereof for the passage of the shank of the tool 13. Disposed within the other end of the casing is a rotatable block 14- which is connected at one end to the flexible driving shaft 15, which shaft is properly connected to a suitable motor; not shown. The other end of the said block is formed with a plurality of clutch faces 16 which are arranged for engagement with similar faces 1'? formed on the adjacent end of a second block 18 disposed in the casing. Secured in the center of the clutched face or end of the block l l is a longitudinally ex tending pin 19 which extends into a bore 20 formed in the adjacent end of the block 18, and on which the block 18 may idly turn.
The other end of the block 18 is slightly reduced, externally, and is threaded to receive thereon the sleeve 21. Centrally on the outer end of the block 18 there is formed a bifurcation 18 in which are pivotally connected the tool gripping fingers 22. The outer ends of these fingers are externally beveled as shown at 22. These fingers receive therebetween the head of the shank of the tool 13, as clearly seen in Fig. 2. The inner face of the outer end of the sleeve 21 is also beveled, as at 21, whereby the fingers will be forced into firm gripping engagement with the tool when said sleeve is screwed inwardly. and release the fingers and permit the removal of the tool when screwed outwardly.
Upon removal of the cap 11, from the easing, the sleeve 21, together with the block 18, and the tool 13. may be easily slipped from the casing. after which the tool 13 may be removed by unscrewing the sleeve, and a diii'erent tool suhstituted.
It will thus be seen that when the tool is properly secured within the chuck, and the block 14: set in motion by the flexible shaft. the clutch faces thereof will engage with the clutch faces of the block 18, and if the tool is pressed against the work. the said block 18 and the tool will be properly rotated. Upon release of the pressure of the tool against the worln the block will automatis cally release itself from the clock 14 and come to rest, thereby preventing the actuating of the tool and the elimination of dan ger of injury to the tool, should the chuck he laid down, as well as injury to the work man which would be liable should he come into contact with the tool while it is in rapid rotation.
There is thus provided a novel and eilec tive device of this character, and one wherein the tool as well as the workman are protected from injury when the tool is not be engage, and whereby the tool will be pre-' mg used. and the power is still applied to l vented from rotation when the tool is not in use. It will also be noted that the pin 19, by its engagement in the bore 20, holds the two blocks in proper alinement for the engagement and disengagement of the clutch faces, as the tool and holder move Within the limits of the outer end of the casing and the asdjacent end of the block 14.
What is claimed is:
A power driven chuck including a nonrotatable casing forming a hand grip, one end of the casing having an internal sh0ulder, a driving clutch rota-table Within the casing and having a shoulder engaging the firstmamed shoulder, a central longitudinal stem extending from the inner end of the clutch member, and a chuck member rotatable in the other end of the casing and having a clutch face on the inner end for engagement With the first clutch and a central opening in said end for the said stem.
I In testimony whereof I aflix my signature in the presence of tWo Witnesses.
CHARLES O. DOMINY.
