EDWARD PFAUSER, OF MILWAUKEE,
memo PrEN TW'ISCONSIN, ASSIGITOR TO BLACKHAWK MANUFACTURING CGEJIQANY, F IY'IILWAUKEE, WISCONSIN SOCKET ATTACHMENT non 'rooLs 3 Application filed September 20,- 1929. Serial No. 384,014.
This invention relates to new and useful improvements in socket attachments for tools.
provision of novel means for attaching a socket engaging member to a shank of a tool whereby to securely retain the socket in position upon the shank and eliminate the possibility of the socket becoming loosened and detached from the shank through vibrating or jarring movement.
Another object of my invention is the provision of an improved attachment for socket tools wherebya socket member may be quickly and readily engaged with the shank of a tool and securely maintained upon the shank of a tool until manual y operated and includes yielding means for preventing the fastening means from becoming loosened and accidenta ly detached.
A further object of the invention is the provision of a device of the above character which includes a tool shank formed with a transverse threaded aperture in which is adjustably mounted a stop plug adapted to be moved into engagement with the bore formed in the socket sleeve to securely attach the socket to the tool socket being formed with an aperture to receive therethrough a manually operated tool for adjusting the stop plug.
With the above and other objects in View, the invention consists in he novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawings wherein:
Figure l is a side elevation of a tool shank constructed in accordance with my invention with parts thereof illustrated in vertical section;
Figure 2 is a similar view showing a socket in section and in retained position upon the shank; v
Figure 3 is a transverse sectional View.
As a general rule, the sockets which are illustrated in the accompanying drawing, are generally indicated by the numeral 1 and are formed. with I an engaging sleeve 2. These One of the objects of my invention is the shank, the sleeve of the sleeves usually have a transverse threaded ap-V erture in which is mounted a set screw 3, said set screw being manipulated by a hand wrench or the like, engaged within the hexagonal bore 4; of the set screw for adjusting the screw in the aperture. This type of socket is at present on the market but it has been found that these set screws become loosened under constant agitation and vibration so that they are somewhat impractical, and in order to overcome the objections of having the socket loosened under vibration, I provide a socket with a transverse opening 5, and diametrically oppcsitethe opening 5, I provide a recess 6 in the wall of the socket opposite the opening 5.
The opening 5 and recess 6, as indicated in Figure 3 are at right angles to the set screw 3, so that the opening 5 and recess 6 can be used in conjunction with the set screw 3 in order/co provide the socket sleeves 2 with means whereby they can be easily attached to the type of tool shank on the market at the present vtime, or attached to my improved shank.
In the present instance, the tool shank 7 is formed with reduced outerend 8 which is provided with a transverse threaded bore 9. Between the main portion of the shank 7 and the reduced portion 8 isan annular shoulder 10 against which the inner end of the sleeve 2 of the socket abuts when the socket is laced in operative position as shown in :1 igure 2. i
Adjustably mounted within the threaded bore 9 is a threaded plug 11, having a reduced smooth portion 12 which is adapted to be projected into the recess 6 in the sleeve 2 after the sleeve has been fitted onto the reduced portion 8 of the tool shank. In order to adjust the plug 11. within the threaded bore 9, any type of hand tool provided with a hexagonal end portion is extended through the opening 5 and into the bore 9 whereit engages the hexagonal bore 13 in the; plug and through rotation of the plug, the end 12 thereof may be projected beyond the exterior surface of the reduced portionS or drawn into the bore 9 as required.
In order to eliminate any possibility of a jarring or vibrating movement loosening the plug, and t plug 11, a coil spring 14 is placed within the bore 9 and retained therein by means of an overhanging lip 15 which extends annularly so that itsouter edge practically aligns with the wall of the opening 5. The coil spring 14 is positioned between the overhanging lip 15 and the inner end of the plug 11, .as shown in the drawing so that the tension of the coil spring will always urge the plug l-l-outwardly whereby when the reduced portion 12 thereof is engaged with a recess 6, the spring will prevent inward movement of the ins retain the sleeve 2 of the so ket in position upon the reduced portion 8. This construction will eliminate the possibility of the reduced portion 12 from bei g removed from the recess 6 when the socke is in operative position, and will securely hold the same in place.
From the above, it will be apparent that the socket may be used on an ordinary type of shank of the shape illustrated by using the set screw 3, or the socket can be used upon my improved shank by placing the sleeve 2 in position on the reduced portion 8, as shown in Figure 2, and then turn the plug 11. until the reduced portion 12 is engaged within the recess 6. This operation is carried out by inserting a tool engaging part through the opening 5, into the bore 9 and thence into the bore 13. The socket can also be quickly re leased from the tool shank by adjusting the plug 11 inwardly in the bore 9 against the tension of the spring 14 so as to quickly remove the socket from the shank.
'It is believed from the foregoing that applicant has provided an improved socket as well as a corresponding shank whereby the socket may be used on a well known type of tool shank or used in connection with my tool shank.
At this point, I wish to call attention to V the fact that the reduced portion 8 of the shank 7 is formed with oppositely disposed rounded walls 16 and oppositely disposed flat portions 17 and in forming the bore 9 in the reduced portion 8, it is preferable to extendthe bore through the flat side walls of the shank so that the set screw 3 can, iffound desirable, be used in connection with my im-' proved fastening means and engaged with one or" therounded side walls 16.
lVhile I have shown and described the preferred embodiment of my invention, it will be apparent that slight changes may be made in the construction when putting the invention into practice without departing from the spirit of the, same or the scope of the appended claim.
I claim: 7
A device of the class described including a shank having a transverse threaded opening, an inturned lip at one end of the opening, a socket member havinga sleeve adapted to be mounted on the shank, said sleeve being 1 lip, a reduced portion at the outer end of the plug adapted to be engaged in the recess, said plug having a central bore in its inner end whereby a tool can be inserted through the opening in the sleeve .for adjusting said plug and a yieldable member disposed between the plug and the lip.
In testimony that I claim the foregoing I have hereunto set'myhand at Milwaukee, in the county of Milwaukee and State of WVisconsin.
