LOCKING DEVICE FOR BORIHG OR OTHER TOOIS.
. Application filed April 28, 192].- Serial No. 465,335.
To all whom it may concern:
Be it known that I, GEORGE J. KENGEL, a citizen of the United States, residing atDetroit, county of Wayne, State of Michigan, have" invented a certain new and useful Improvement in Looking Devices for Boring or other Tools, and declare the following to be a full, clear, and exact description of the same, such as will-enable others skilled in the art to whichit pertains to make and use the same,- refe rence being had to the accompanying drawings, which form a part of this specification.
My invention relates to an improvement in boring. tools or other tools of a like character in which the cutting end is detachable from the socket or shank of the tool.
-One of the objects of this invention is to provide means for securing the cutting end of the tool in its socket against accidental release; the construction being such however that it may be readily removed when re uired. 4
further object of the invention is to provide for maintaining the cutting end in registered relation to the flutes of the socket proceeds the invention further resides inthe combination and arrangement of parts and in the details of construction hereinafter that changes may be made in the precise embodiment of the invention herein disclosed without departing from the spirit of the same.
In the accompanying drawings forming part of this specification: I
Figure 1 is an elevation partly in section, of a boring tool having a detachable cutting end.
Fi'gure 2 is a cross-sectional View taken on or about line 22 of Figure 1, on a line with the transverse locking pin, showing the relative position of the parts upon-the initial entry of the shank of the cutting end into the socket portion of the tool.
Figure 3 is a similar cross-sectional view showingthe shank of the cutting end rotated with reference to the socket portion of the tool that the transverse locking pin may secure the cutting end thereto.
cured by the yieldable locking means' against accidental displacement.
Figure 5 is a similar cross-sectional view to that shown'in the preceding figure the shank of the cutting end however bei rotated in order that the yieldable loo 'ng device may maintain the cutting end in a fixed registered position with the flutes of the socket' portion. l I
Figure 6 is a fragmentary perspective view of the flattened cutting end.
Figure 7 is a side elevation of the yieldable locking device and supporting plug in which it is lodged.
Figure Sis a perspective view of the yieldable locking device removed from the plug with parts broken awa to disclose the socket in which a spring is lodged to actuate the device.
Figure 9 is a side elevation of a modification of the tool.
Figure 10 is a cross-sectional view taken on or about line 10-10 of Figure 9 showing portion of .the shank of the the flattened portion of the shank of the cutting end as it initially passes the locking ribs inthe socket: portion of the tool,before being rotated therein.
Figure 11 is a similar sectional view showing the shank of the cutting end rotated into locking engagement with the ribs of the socket portlon.
Figure 12 is a fragmentary perspective view of the shank of the cutting end shown in Figure Q indicatin in dotted lines the flanges of the plug 0 the locking device overlapping the flattened sides of the shank.
Referring now to the letters of reference placed upon the drawings:
A, denotes the bod portion of a drill or similar tool provided with a socket B, to receive the shank C, of a detachable cutting end D. E, indicates a transverse pin extending into the socket opening,-its ends being supported by the annular ,wall forming the socket of the tool. The shank C is flattened as indicated at C (see Figure 6) that into the socket of the tool.
portion of the latter, whereby upon a slight rotation of the shank the cutting end may be locked in the socket of the tool.
F, denotes a plug lodged in the socket B having one or more downwardly extended flanges F, adapted to overlap the flattened portions 0' of the shank. G, is a movable sleeve having a closed outer end fitted in a transverse bore provided in the plug F ;-the closed end of the sleeve G'being arc-shaped to conform to the periphery of the plug., Lodged in the sleeve G is a sprin H, one
' end of which bears against: the en wall of i the sleeve and the other against the Wall of the plug to force the sleeve outwardly. I, indicates a screw extending throughthe wall of the socket having a rounded end adapted to alternately enter the recesses G and Gr formed in the end of the sleeve connected together by a peripheral groove G". In the modification shown in Figures 9, 10, and 11, the socket B of the tool is provided with oppositely disposed flat-faced projecting ribs'B, to secure the shank in the socket of the tool,-the shank of the tool bein formed with two flattened surfaces C, that it may pass the ribs B upon its entry into' the socket of the tool.
Having now indicated the several parts by reference letters the construction and operation of the device will be readily understood.
To secure the cutting end in the socket portion of the tool the shank is inserted so that the flattened end C may pass the projecting transverse pin E; -the flange F of the plug F overlappin the flattened end as, shown in Fi re 1. ile in this position the end of t e screw I is lodged in the recess G of the sleeve G; the sleeve being depressed against the action of the spring H, when forcing the shank of the cutting end into the socket portion of. the tool. The
shank is then given a slight rotation causing the plug F and the sleeve G, lodged therein to rotate with it, due to the flanges F of the plug overlapping the flattened portions of the shank;the plu becoming an extension of the shank. %heset screw I is thus caused to traverse the peripheral groove G into the recess G whe'reby the flutes of the cutting end may be maintained in registration with the flutes of the body portion of the tool. In rotating the tool the transverse pin E, will enter the peripheral groove C extending from the flattened portion of the shank, thereby locking the cutting end in the socket of the tool ;at the same time the set screwv I serves to main tain the shank in its adjusted position against accidental displacement.
In the modification shown in Figure 9 the shank of the cutting end is flattened on opposite sides'tha't it may pass the oppositely disposed ribs B in the socket of the tool upon'the entry of the shank therein.
As will be readily understood the ribs B in the socket'of the modification are em ployed in place of the transverse pin E previousl described. In the modification the plug is provided with two downwardly extended flanges F overlapping the flattened portion of the shank. To assemble the parts the shank of the cutting end is inserted in the socket of thetool-the flattened ends of the shank registering with the projecting ribs B ,"while the end of the shank projects between the spaced flanges of the plug. The plug is then rotated whereupon the sprin actuated sleeve, willbe depressedto permit the screw I to pass from the recess G by way of. peripheral groove G to the recess Gr 1n the sleeve. Upon the screw entering the recess G the cutting end will be held in the socket portion against accidental rotation.
It will be understood that the set screw I in the wall of the tool socket is so positioned that when lodged in the recess 8* of the sleeve G, the downwardly extending flanges F of the plug F will be in proper position to receive and-overlap the flattened end C of the shank C upon theentry of the latter into the socket ;--the plug F is thus secured against accidental rotation or displacement peripheral groove, and an element supported in the wall of the socket portion adapted to be alternately lodged in the recesses of the spring actuatedmember to secure the plug and the shank of the tool against accidental displacement.
2. A tool including a socket portion, a removable cutting end provided with a shank having a flattened end adapted to enter said socket portion, means for securing the cut-,
ting end in said socket portion, a rotatable plug lodged in the socket portion provided with a flange adap ed to overlap the flattened end of the shank, a spring actuated sleeve lodged in a transverse bore in said plug having a closed outer end provided with spaced recesses, connected by a periph-' eral groove, and a set screw supported in the wall of the socket portion adapted to be alternately lodged in the recesses of the spring actuated sleeve to secure the plug and flattened at its end and adapted to enter the socket portion, with a peripheral groove in said shank extending from the flattened portion to receive a locking pin, a transverse docking pin supported in the wall ofthei socket portion adapted to enter said peripheral groove in the shank, a rotatable plug lodged in the socket portion in advance of the shank of the cutting end and provided with a flange overlapping the flat 15 tened end of the shank, aisleeve lodged in a transverse bore in said plug, its closed outer end provided with spaced recesses connected by a peripheral groove, a spring adapted to actuate said sleeve and a set screw supported in the wall of the socket portion adapted to alternately enter the recesses of the spring actuated sleeve to secure the plug and the shank of the tool When adjusted against accidental displacement.
"In testimony whereof, I sign this specification in the presence of two witnesses.
