Application filed Decembertl, 1824:.v Serial No. 758,075.
The present invention provides a tool of the nature of a spanner or nut wrench which embodies provision for receiving a cap screw or a plurality of nuts and which is of special advanta when changing pneumatic tires or per orming other work requiring the loosening and ti htening of a number of nuts, screws and olts.
Other objects and advantages will be apparent and suggest themselves asethe nature of the invention is understood. v 1
While the drawings illustrate. an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from thenature of the invention.
Referring to the accompanying drawings forming a part of the specification,
Figure 1 is a side view of the preferred form of tool, the pressure piece being in section Figure 2 is an end view of the holder for the bolts and nuts, showing a portion of the brace,
Figure 3 is an enlarged longitudinal sectional view of the nut and bolt holder having a portion of the brace attached,
Figure 4 is an enlarged sectional view on the line 4-4c of Figure 1, and
Figure 5 is an enlarged sectional View on the line 5-5 of Figure 1.
Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters,
The numeral designates the holder for the nuts, bolts, screws, and the like, the same being tubular and constituting a magazine, and for convenience of operation an ordinar brace 11 is attached at one end to an en of the holder 10, the latter being closed at one end by means of a plug 12 through which and the holder passes an end of the brace 11 which is made secure by means of a rivet or pin 13. The outer or working end of the holder 10 is reinforced by means of a ferrule or band 14 which has a portion cut away as indicated at 15 toreceive a spring 16 which normally exerts a pressure upon a retainer 17 to hold it projected into the ball or opening of the holder 10 to prevent outward displacement of the nuts, bolts or screws placed within the holder or received therein when removed from the cooperating part, thereby obviating the necessity of receivin the same inthe hand which is objectiona le, particularly when changing tires or performing other work when it is desired not ,to. soil the hands. The retainer 17 preferablyfconsists of aball.
A release 18 is disposed-at one side of the holder 10vand is mounted in the ferrule or band 14 and islprovided at one end with a crank and' at'the opposite end with a lift 19 whichris disposed beneath the free end of the spring 16 so that when the crankof the release is moved outwardly, the free end of the spring 16 is correspondingly thrown outward thereby relieving the retainer 17 of inner pressure so that the nuts,
screws, or the, like contained within the holder may readily discharge. The crank portion of'the release normally lies against the side of the holder thereby preventing accidental operation thereof or injury thereto by striking an object.
It will be understood that the release 18 is to be used only when it is-desired to emp-" capacity to hold all of the nuts in an un-- screwlng operation, as for instance in removing the head bolts of an internal combustion engine. In screwing on nuts from the magazine it will be apparent that the bolt end will engage with the first nut in the magazine and will be pulled down as the nut is screwed down on the bolt and the wrench will be self releasing.
A follower '20 is located within the holder 10 and is normally pressed outwardl by means of a coil spring 21 which is sol ered or otherwise attached at its inner end to the plug 12 and at its outer end to the follower and this spring normally urges the discharge of an article contained within the holder, casual displacement of such article bein prevented by the retainer 17, but whic yields to admit of entrance or removal of the article by the application of sufficient force thereto,
What is claimed is A device of the class described comprising a magazine having an opening through the side thereof to its holdmg chamber, a retainer for the lowermost article in said chamber occupying said opening, a contractile spring surrounding the chamber having a spring displacing element located and being in contact with the retainer to intermediate a portion of the spring and hold it in place and permit yielding therethe exterior of the magazine. 10 of, said magazine having a band surround- In testimony whereof I afiix my signaing the same, said band having a recess acture.
commodating said s ring, and a release member carried by said band, said member CLYDE R. WORK.
