In one form of chuck structure the toolengaging or socket member of the chuck is member and therefore to the tool engaged therein. The socket member is subject to considerable wear, which makes it expedient that it be removable for replacement. In actual use it has been found a very difficult matter to remove said member from the sleeve after the drill has been in operation for some time, V
. 'eel or other tool. So i'ar-jas-thusdescribed,
due to the binding of the screw threads. As a consequence upon rotating the socket mem her in an endeavor to remove it from the sleeve, the sleeve usually rotates with the;
chuck.
One of the objects of the present, inven- .1
tion is to provide means of a simple nature whereby the sleeve can be locked aga nst rotation. As a consequence it 1s pos t vely v heldso that the socket or tool-engaging member can be turned and consequently unscrewed from said sleeve.
In the accompanying drawlngsi Figure 1 is aside elevation of the chuck end of a tool with the sleeve locking means i v s1de the bolt and the bolt is turned, as, shown 1 in place thereon, Flgure 2 1s a longitudinal sectional view therethrough,

" of the invention.
bolt is in the position shown in Figure 3, in which case the stud 25 is in the notch 24, and the cut-away seat 20 is facing the rotary sleeve 9, so that said sleeve can rotate within the housing 8. When it becomes desirable to detach the socket member 12 the sleeve 9 is rotated until one of the flat seats 10 is alongside the bolt, said bolt is then given .a longitudinal movement to disengage the stud 25 from the socket 24, and the bolt is turned until its body extends across said seat 10. The sleeve is now locked, whereupon it a tool is applied to the socket member 12, 0b-
viously it can be unscrewed from the sleeve. From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be I apparent to those skilled in the art, without further description and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages What I claim, is
1. In adrilling tool, the combination with a housing, of afdriving sleeve rotatably mounted in the housing, a tool-receiving wear member detachably fitted to the sleeve and normally rotated'therewith to rotate a tool deta'chably engaged therein, and means for Yter'nporarily securing the sleeve against roi i mounted in the housing, a tool-receiving wear "bushing. j
tation in the housing to permit the tool-receiving member being moved with respect to the sleeve to detach said member.
2. In a drilling tool, the combination with a housing, of a driving sleeve rotatably bushingscrewed into the outer end of the sleeve and having a longitudinalopen ended I socket for. the reception of the tool, and a holding bolt carried by one side of the housing and adapted to engage with one side of the sleeve for temporarily holding the sleeve against its normal rotative motion in the housing to permit the detachment of the 3. In a drilling tool, the combination with :a housing, of a driving sleeve rotatably mounted in the housing and having opposite flat faces'for engagement by holding jaws,
a tool-receiving bushing screwed into the outer end of the sleeve and'having a longitudinal open ended socket for the reception of the tool, and a holding bolt rotatably mounted in one side ofthe-housing and having a" portion that is adapted to bear against one of the flat facesiof the'samie for temporarily holding the sleeve against its norm-a1 rotative motion in thehousing to permit the-detachfinent of the bushing. 1 In testimon' whereoffl afiixmy signature.
