TIRE-BOLT WRENCH.

SPECIFICATION forming part of Letters Patent No. 762,049, dated June 7, 1904.-

Application filed March 28, 1904:.

T0 (LZZ whom it may concern:

Be it known that I, FRANK O. GIBSON, residing at Ballston,in the county of Alexandria and State of Virginia, have invented a new and Improved Tire-Bolt Wrench, of which the following is a specification.

My invention relates to an improved tirebolt wrench designed to provide a's imple and practical tool for quickly and conveniently removing nuts from bolts or applying nuts to bolts without danger to the felly and to provide means for holding a plurality of nuts to be screwed onto alternate bolts.

Vith other objects in View, which will be hereinafter apparent, the invention consists in certain novel constructions and combinations side the telly and tire, so that the nut cannot be turned over the threads of the bolt. This is so by reason of the fact that there is no niche in the head of the bolt to receive a screwdriver with which to hold the bolt while turning off the nut, and even if there was itwould become obliterated or worn off by the wear of the tire. This difliculty is further exaggerated by the fact that the nut and bolt from constant wetting become rusted together, so as to render the starting of the nut on the bolt more difficult. The result is that in many cases the end of the bolt carrying the nut has to be cut off'with a cold chisel and at the oxpense of much time and tedious labor and the scarifying of the telly. Again, in applying. nuts to bolts in the assembling of the wheel the same objection to turning of the bolt is present, and hence I have designed my invention to operate to accomplish the results desired and avoid the difliculties just enumerated.

Serial No. 200.376. (No model.)

Referring now to the accompanying drawings, Figure 1 is a perspective view showing my invention applied for use. Fig. 2 is a longitudinal section thereof. Fig. 3 is a crosssoction on the line 3 3 of Fig. 2. Fig. 4 is a similar view on the line 4: 4 of Fig. 2. Fig. 5 is a detail perspective View of the nut-hold- Fig. 6 is a detail end elevation of my invention. Fig. 7is a detail perspective view of the clutch-bar detached.

Referring now to the accompanying drawings, in which like numeralsand letters of reference indicate like parts in all the figures, 1 designates a handle member, at one end of which is formed a U-shaped yoke or straddling member 2, whose free end terminates in ears 2 for the purposes presently explained, and where the end 2? and the enlarged portion 1 of the handle member 1 join the said handle is provided with a bore 1 and a slotted portion '1", as shown. The portion 1 of the handle has shoulders 1 1 to cooperate with the shoulder 3 of the lever, fulcrumed, as at 2, with its end 3 in the slotted portion 1 of the enlarged portion 1 of thehandle, and the said portion 1 has a bridge-piece 1 for the lever 3to rest on when gripped by the hand of the operator and to hold the said lever parallel to the handle 1.

Held for longitudinal movement in the bore 1 is a clutch-bar I, having a pronged' end 4: and a rack-face 4: with which face the pawl 3, fulcrumed at 5 in a cut-away portion 3 of the lever, cooperates. The bar 4 has an elongated groove 4. in its under face, in which the end 5 of the set-screw 5, held in the threaded aperture 5 of the handle 1, projects to limit the movement of the said bar in its longitudinal direction. i

l/Velded or otherwise secured to the ears 2" of the member 2 is a bearing member 6, having a flange 6 and an annular bore'6",in which seats the annular hub 7 of the wrench 7, which includes an annular disk 7 of greater diameter than that of the hub-7. its peripheral face provided with rack-teeth 7 for the purpose presently to appear. The hub 7 is so mounted in the bore 7 that it will be free to turn on its longitudinal axis and is provided with an annular groove 7 to The disk 7 has bore 6" of the member 6.

cooperate with the end 8 of the screw-lug 8,. held in the threaded aperture 6 of the bearing member 6, the screw 7 and the lug 8 serving to prevent the head 7 leaving the bore 6".

9 designates a ratchet-arm having a handle 9 and an enlarged end 9, apertured, as at 9", to receive the flange 6 of the member 6, whereon it has free movement in the arc of a circle perpendicular to the axial line of the Upon the arm 9 a Y-shaped latch 10 is fulcrumed, as at 10, to allow one of its arms 10" to engage the rackteeth 7 c to cause the wrench 7 to rotate with the arm 9.

The wrench 7 has a square and tapering bore 7 e to receive the magazine 11. (Shown in detail in Fig. 5, by reference to which and to Fig. 2 it will be seen the magazine 11 is of elongated shape and adapted to contain several nuts of one size, its outer end being formed with a bridge or closure piece 11", to which the coil-spring 12 is attached, and which coil-spring 12 forces the nuts 13 toward the inner or open end of the magazine.) The sides of the magazine 11 are slitted to form spring portions 11" 11", having nibs 11 at the ends to retard or check the premature exit of the nuts from the magazine, but which are so arranged as to readily allow the nuts to pass out of the magazine during the operation of securing them to the bolt 14:. By providing different sizes of magazines different sized nuts may be removed or secured to the bolts by simply introducing in place of the one magazine other magazines of a different size.

From the foregoing it will be seen that when the operator desires to apply a nut to the bolt 14, passing through the whecl-felly 15 and tire 16, he places the wheel in a horizontal position and adjusts the implement, as shown in Fig. 1, with the bar 4 against the bolt-head 14: and the wrench 7 against the nut end of the felly. The parts are tightly held in such position by reason of the lever 3 and its pawl connections with the rack-face 4" of the, bar 4:. After the parts are in such position it is only necessary to operate the arm 9 to impart rotary motion to the wrench 7 and screw the nut onto the bolt. To remove the nuts from the bolts, it is only necessary to reverse the direction of rotation of the wrench 7, which is done by simply reversing the latch 10, as shown in dotted lines in Fig. 6.

When used exclusively to remove nuts from the wheel, an empty magazine is preferably placed in the wrench 7, so that several nuts may be received thereby.

By providing the U-shaped member and the adjustable bar 4 the implement may be used on Wheels of a variety of sizes without changing the correlative arrangement of the members 6 and 1, and by providing a magazine nuts of different sizes can be readily applied Having thus described my invention, what I I claim, and desire to secure by Letters Patent, is-
