MAGAZINE WRENCH n Filed April 18,`194o` Patented Nov. 5, 1940 UNITED STATES PATENT OFFICE 5 Claims.

This invention relates to magazine wrenches in which a. plurality of nuts may be stored as they are removed from position, one .of the objects of the invention being to provide a wrench of 5 this character having socket means of such nature that the axis of the nut and the axis of the tool may be varied so that theaxis of the nut may be alined with a bolt where it is impossible. on account of obstructions, to bring the axis oi the tool into annement with the axis or the bo1t.

This difiiculty has chieily been found in connection with the construction of some demountable wheels, where it is frequently impossible to get the tool into` exact alinement.

A further object of the invention is to produce a'socket construction of the general character outlined which is provided with resilient means which will maintain an unrestrained nut in alinement with the tool, without the use of bulky external attachments which would interfere with the use of the tool in a conned space.

A ,still further object of the invention is to produce a magazine wrench provided with a series of internal guide strips or members which P will hold the stored nuts in axial alinement and against independent rotation, so that they may always be fed in proper relation to the socket or operating end of the barrel or magazine compartment. v

Another object of the invention is to produce a wrench of the 'general character outlined of strong, durable, efficient and inexpensive construction, and in orderthat it may be fully understood, reference is to be had to the accompanying drawing, in which:

Figure 1 is a section through a portion of a demountable wheel indicating the tool applied thereto at an angle to the axis of a wheel securing bolt.

Figure 2 is an enlarged section on the line II-II of Figure 1.

Figure 3 is a section on the same scale as Figure 2, taken on the line III-III of Figure 1.

Figure 4 is an enlarged fragmental longitudinal section of the bolt-engaging end of the tool and showing the same applied to a nut and coaxially disposed with relation to the nut and bolt.

Figure 5 is an end view oi Figure 4with the nut shown in dotted lines.

`Figure 6 is a view partly in side elevationv and partly in longitudinal section, the body portion 1 constituting a tube which is internally hexagonal 'in cross-section.

55 In the said drawing, Where like reference charj acters identify corresponding parts in all of the figures, I indicates the tace of the axle drum of a motor car. 2 the plate or securing portion of a demountable wheel which is adapted to be se- 6G cured to the drum portion I, 3 the hub portion of said wheel to which the spokes are attached. and I tne hub stiiiening and covering plate securing ange ofthe hub.

The wheel plate 2 is provided with a series of openings adapted to be received on a series of spaced stud bolts 6 projecting from and carried by the axle drum I. As the wheel must not only be secured. but also aimed, the openings in the plate 2 are contoured to receive co-nical portions 1 of securing hexagonal shaped nuts 8. It will be understood that the nuts may be of any shape, and that the tool is correspondingly shaped, and of suillcient diameter to receive the nuts.

Referring to Figures 1 and 4, it will be noted that the relation of the axis of the securing bolts 6 to the cover plate retaining flange 5 of the hub, is such that a magazine wrench cannot be alined with any of said bolts, but must be applied at` an angle thereto. The tool of the invention is, therefore, constructed as follows:

9 is a cylindrical barrel of suillcient length to accommodate any desired number ofA nuts, by preference at least as many as are required to retain one wheel and aspare wheel in position. The bore of the barrel 9 is of sumcient size to receive the nuts. One end of the'barrel 9 is closed by a plug I0 having a cross passageway II, and being equipped with a spring-advanced ball I2 intersecting said passageway. To provide a handle for the tool, a bar I3 is projected through the passage II and is held by frictional engagement oi? the loall I2. One end of this bar-may be formed in a Wedge-shaped portion I4 which may be conveniently employed in removing the cover plates usually used with the type of demountable wheels illustrated.

Welded or otherwise secured to the other end of the barrel, or made integral therewith, is a hexagonal socket (the socket being internally shaped according to the shape of the nuts with which it is to be used), having its outer end I5 of such internal size `and contour as to snugly t over the nuts with which the tool is to be used, and the internal length of said socket being at least as long as the overall length oi a nut. The socket is enlarged rearwardly as at I8 so that a nut may rock at its rear end within the socket. One convenient meansof providing such an enlarged chamber for the rocking of the nut, is to progressively increase the internal diameter of the socket from the operating end to the opposite end thereof as illustrated in Figure 4. With a socket of this character and with the tool positioned with its longitudinal axis in a horizontal plane, it will be apparent that a loose nut would normallyrest against the bottom wall of the socket, with its longitudinal axis consequently extending at an angle'tothe axis of the socket end of the barrel.

With a barrel having a cylindrical bore, means so must be provided to prevent the nuts from rotating within the barrel, as they may become jammed by the expelling means Within the socket, as will hereinafter appear. To provide such 5 a retaining means, the outer ends of a pair of guide strips or straps II, arranged on opposite sides of the barrel to embrace the opposite faces of a nut, are inserted and welded between the abutting ends of the socket and of the barrel.

10 The opposite ends of said guide strips are secured in any suitable way between the plug I and the proximate portion of the barrel or tube 9.

'- I.. Slidingly fitted within the barrel is a follower I8 having a nut engaging portion I8a so made 15 that the rear end of a nut can shift its position on the face of the portion I8a in order to center itself at its rear end with a bolt, as will hereinafter appear, without throwing the front end of the nut out of line. For expelling the nuts, 20. the follower I8 is under the pressure of a spring I9, which abuis the plug I0 at its opposite end.

To prevent the nuts from becoming jambedk in the socket, to guard against the accidental expulsion of the nuts from the tool, and to insure 25 that, under normal conditions, the axis of the nur sha11`be alined with the axis of the m01, the following mechanism is provided: The socket adjacent its out end is provided with a plurality of equi-spaced balls 20 fitting in openings in the 30 socket with one side intersecting the bore of the socket and their other sides projecting into a groove 2I in the external periphery of the socket. Encircling the socket and entirely within the groove 2| thereof is a coiled spring 22 35 which yieldingly presses said balls toward the axis of the socket.

Figure 6 illustrates a construction corresponding in all particulars to that above described, except that the internal bore 23 of the barrel 40 is of contour to hold the nuts against rotation. The internal bore of the drawing is shown as hexagonal to avoid the use of the guide strips I1 of Figures 1 to 5.

4 Operation -Assuming that the magazine is charged with a plurality of nuts 8, the foremost nut will be held by the force of the spring vI9 applied to the follower and the preceding nuts, pressed 50 against the retaining balls 20. The nut will consequently be held with the axis of its threaded bore in the longitudinal axis of the tool. The operator will now approach the tool, in angular relation (as shown in Figure 1), if it cannot be v55 applied in alinement, to the bolt on which the rst nut 8 is to be threaded, and will thrust the tool forwardly without rotating the same, until the `end of the socket comes into abutment with the face of the plate 2. During this move- 60 ment, the bottom edge of the bore of the first nut 8 will have contacted the bottom edge of the bolt 6. and the nut will have been caused to rock within the socket I 8 so that its threaded bore comes into alinement with the bolt 6. This 65 will be true regardless of the position of the l threads on the bolt and nut, since' the nut is held centered in the socket by the three spring advanced balls 20. The operator may now commence to rotate the tool and the nut will prop- 70 any mesh with the bolt threads. It win be noted that as the small end I5 of the socket I6 snugly embraces the nut, it will not be possible for the socket to rotate around the nut. A nut is removed by reversing the operation above described, and it will be evident that each succeeding nut presses the preceding nuts into the magazine against the action of the spring I8. The final nut 8 is held against expulsion by the fact that the balls 20 intersect or project into the bore of the socket, as common in devices of this kind.

From the above description, it will be apparent that While I have described and illustrated what now'appears to be4 the preferred construction, itis to be understood that I reserve the 10 right to all changes properly falling within the spirit and scope of the invention and without the ambit of the prior art.
