TIRE-BOLTING- MACHINE.

Application filed July 8, 1914. Serial N 0. 849,756.

To all whom it may concern Be it known that I, BENJAMIN F. MGCUL- LOUGH, a citizen of the United States, residing at Teague, in the county of Freestone and State of Texas, have invented a new and useful Tire-Bolting Machine, of which the following is a specification.

The present invention appertains to wheelwright machines, and relates more particularly to an apparatus for applying and removing the bolts to and from the felly and tire of buggy, wagon and other vehicle wheels.

This invention contemplates the provision of an apparatus of the nature indicated, embodying a unique assemblage of component parts, to enhance the utility of the structure,

and the apparatus being improved generally to increase the efficiency thereof.

With the foregoing and other objects in view which. will appear as, the description proceeds, the invention resides in the combination and arrangement of parts and .in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed Without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein:

Figure 1 is a plan view of the improved apparatus. Fig. 2 is a side elevation there of. Fig. 3 is an enlarged longitudinal section of the apparatus, the section being taken approximately on the line 33 of Fig. 1, parts being broken off or omitted. Fig". i is a cross section taken on the line 4-4: of Fig.3. Fig. 5 is a sectional detail taken approximately on the line 5-5 of Fig. 3. V v

The present apparatus embodies a frame 1 constituting a suitable base 2 having a pair of longitudinally spaced standards or up rights 3 and 4 which carry a casting or yoke 5 at their upper ends. The casting or yoke 5 is provided at one end, above the standard l with an upstandingbearing 6. p

'Journaled through the bearing .6, is a 10in gitudinally arranged tubular stock or sleeve 7 for holding the wrench and, drill hereinafter referred to. One end of the tubular stock 7 is provided with an annular outturned flange 8 and a sprocket wheel 9 is Specification of Letters Patent.

Patented May 4, 1915.

sprocket wheel 9, and around a lower and.

larger sprocket wheel 11 which is keyed or secured upon a longitudinal driving shaft 12 journaled through the standards 3 and a below the casting or yoke 5. That end of the shaft 12 which protrudes beyond the standard 3 has secured thereon, a fly wheel 13 which is equipped with a crank handle 14; for conveniently rotating the shaft 12 man ua'lly, although the same may be operated mechanically, if desired. It is evident at this. point, that the rotation of the driving shaft 12 will impart a rotary movement of higher ratio to the stock or sleeve 7 for the intended purposes which will hereinafter appear.

Fitted snugly within that end of the stock 7 having a flange 8, is a wrench 15 having a nut socket or bore 16 therein for the receptionand passage of the nuts, and a set screw 17 is threaded through the flanged end 8 of the stock 7 to bind or clamp the wrench member 15 in place. A collar or ring 18 is secured upon the other end of the stock 7, and bears or seats against the bearing 6, to retain the stock in operative position, and to prevent the longitudinal movement of the stock and so that when the collar 18 is released, it will enable the stock to be removed or withdrawn from the bearing. The last mentioned end of the stock 7 is also equipped with an inner bayonet slot 19 for the purpose which will presently appear.

A removable drill chuck 20 fits snugly within that end of the stock 7 remote from the end carrying the wrench member 15, and the said chuck 20 is provided with a lug or pin 22 arranged to engage within the bayonet slot 19 of the stock 7 to hold the chuck 20 in place and to cause the chuck to be r0- tated with'the stock. The chuck 20 is bored or socketed to receive thebutt end of a drill bit 23, and the outer end portion of .the chuck 20 carries a set screw 24: for binding or clampingthe drill bit in place.

A clamp member is adjustably mounted upon the casting or yoke 5, and embodies a base 25 seated slidably upon the casting or yoke 5, and having an upturned jaw 26 at that endnearest the stock 7, the jaw 26 being equipped with an upwardly opening recess 27 The said end of the base 25 is also pro- 29 is restrained against longitudinal movesnugly within the longitudinal slot 28*" provided in the casting or yoke 5, and a feed or adjusting-screw'29 is journaled through that end of the casting or yoke 5 having the bearing 6, and is threadedly engaged through the lower portion of the car 28. The screw ment, and may rotate readily, to slide the clamp member longitudinally, and that end of the screw 29 which projects beyond the bearing 6, is equipped with a suitable hand wheel 30 for facilitating the rotationjof the screw. A depending clamping bolt 31 is threadedly engaged to the other end of the base 25, and works within the longitudinal slot 32 provided in the yoke or casting 5, the head of the bolt 31 projecting below the slot 32 for assisting in clamping the base 25 of the clamp member upon the yoke or casting 5.

The invention also embodiesa bolt holding device, which includes an upstanding fork 33. having its shank 34 journaled' or pivotally engaged to or through the casting or yoke5, and a screw 35 is engaged slidably through the arms of the fork 33 .at right angles with the fork, and a hand wheel36 is disposed snugly between the arms of the fork and is threaded upon the screw 35. Thus, the screw 35 is restrained for longitudinal movement, through the fork 33, and the wheel 36 is restrained forrotary movement, in order'that when the hand wheel is rotated, the screw 35 will bemoved longitudinally as desired. Alever 37 is fulcrumed to the shank of the screw 35, and is equipped adjacent its fulcrum, with a bit 38 for engaging the kerf of the head of a tire bolt.

The present apparatus employs a crane or carrier 39, for supporting and manipulating the wheel which is being operated upon. The crane 39 includes a horizontal beam 40 having a slotted casting 41 bolted or otherwise secured to one end thereof and pivf otally engaged over apintle or bearing 42 Securedtothe standard of the frame 1. An inclined base 43 has'its upper end secured to "the free end portion of the beam 40 and has its lower end pivotally engaged to a bearing member 44 attached to the lower end portion of the standard 4. The beam 40' is thus capable of being swung in a horizontal plane toward one "Side or the other of'the frame 1. The crane or carrier 39 may be held at various angular positions, by means of a brace or adjusting bar 45 pivoted ,to the free end of the beam 40, andhaving a series of lower notches 46 adjacent its free end, which notches are engageable over an outstanding arm or bracket 47 rigidly secured to the standard-4. Thus,by disengaging the brace or bar 45 from the arm or bracket 47, the crane may be swung to the position desired, and by engaging the proper notch 46 of the brace or bar 45 over the bracket 47, the crane may be held in the position to which it has been swung.v Y

The beam 40 carries a slide 48 which is capable of rectilinear or 'reciprocatory movements upon the beam, and the slide 48 is equipped with an upstanding spindle 49 for the engagement thereover of the wheel hub.

Adjustable wheelsupporting means is provided, and embodies a lever 50 fulcrumed to one side of the slide 48, and a bar 51 having its lower end pivoted to the lever 50' and provided at its free or upper end with a hub seat 52loosely embracing the spindle49 and adapted to carry the hub of the wheel. The said side of the slide 48 is provided with an arcuate series of notches or sockets 53 into which is engageable, a peg or pin 54 for holding the lever 50 at various adjusted positions, to thereby support the hub seat 52 at variousvertical positions, as desired.

7 An actuating rod 55 for the slide 48 is disposed immediately above the beam 40 and'is engaged slidably through the slide 48, and

the inner end of the rod 55 is linked to a bell crank lever 56 fulcrumed within the casting a The slide 48 carries a set screw 56 for clamping the rod 55 in position relative to the slide, and whereby the slide may be adjusted longitudinally relative to the rod according to the various circumstances. A rod or link 57 has its upper end attached to the lever 56 and has its lower end connected to a treadle 59 by means of a strip 57". The treadle is fulcrumed to the base and is raised by a spring 58, and the lower end of the strip 57? is pivoted to the treadle. The lower end of the link 57 is engaged through the upper angular end of the strip 57 and adjusting nuts 57 are threaded upon the lower end of the said link. This treadle 59 when depressed, will draw the link 57 down wardly, to thereby draw the rod 55 inwardly or toward the fulcrum of the crane beam 40,

and consequently, the slide 48 will be moved proper horizontal plane. The ,slide 48 is also adjusted longitudinally along the beam 40 and with respect to the rod 55, by loosen-' ing the set screw 56, in order that the wheel felly or rim will have its inner side resting against the jaw 26. The base25 of the clamp member is adjusted relative to the bearing 6, in order that the recess or opening 27 will receive the wrench member 15, and thereby thewrench member may project through the jaw 26 to engage the corresponding nut of the wheel when the bolt is being tightened or loosened. It will be observed that the base 25 of the clamp member may be readily adjusted through the medium of the adjusting screw 29 to properly position the jaw 26.. Then, by depressing the treadle 59, which will cause the slide 48 to move toward the standard 4, the felly or rim and tire of the wheel may be moved away from the jaw 26 and wrench member 15, to enable the bolt to be readily inserted through the openings of the felly and tire, and whereby the nut may be threaded upon the inner end of the bolt. lVhen the operator releases the treadle 59, the spring 58 will return the slide to normal position, to bring the felly of the wheel against the jaw 26 and into coiiperative relation with the stock 7, the nut-being received by the socket 16 of thewrench member 15. The bolt may then beheld against rotation, by manipulating the lever 37 properly to engage the bit 38 with the kerf of the head of the bolt. By pressing the lever 37 toward the wheel, the bolt will not only be held against rotation, but the felly will be clamped between the lever 37 and the jaw 26. Then, by rotating the shaft 12, the stock 7, and wrench member 15 carried thereby, may be rotated for tightening the nut, or conversely, when the nut is to be removed, the shaft 12 may be rotated in the opposite direction to this end. By releasing the lever 37, the bolt and wheel felly will be released, and the wheel may then be reset for applying the next succeeding bolt.

It is to be noted that the screw 35 which carries the lever 37 may be adjusted axially, by rotating the hand wheel or nut 36, and the fork may be swung, in order that the lever 37 may be properly positioned and manipulated for engaging and holding the bolt. The lever 37 may thus be adjusted and moved in various directions.

In case the bolt holes are irregular and r not radial to the wheel, the wheel may be adjusted to one side or the other of the longitudinal median plane of the machine, by manipulating the brace or bar 45 as above described, in order that the bolt holes may be brought in alinement with the wrench as to hold the wheel felly and tire adj acentv the drill bit 23, so that when the treadle 59 is depressed by the operator, the wheel felly and tire will be moved into engagement with the drill, bit, it being noted that the drill 'bit may be readily rotated during the movement of the wheel felly and tire over the same.

The present apparatus may be adjusted for various sizes of wheels, and is otherwise of advantage as will be apparent to the wheelwright or persons skilled in the art.

Having thus described the invention, what is claimed as new is:

1. Ina wheelwright machine, a frame, a jaw carried thereby for the seating of a wheel felly thereagainst, an upstanding fork having a shank journaled to the frame, a screw slidable through the arms of the fork, a nut threaded upon the screw and disposed snugly between the arms of the fork, and a lever fulcrumed to the screw .and havin a bolt-en a in element.

2. In a wheelwright machine, a frame, a rotatable wrench member carried thereby, a clamp member including a base slidable upon the frame, the base having a jaw at one end provided with an opening for the reception of the wrench member, and having an ear at the said end slidable through the frame, an adjusting screw carried by the frame and threaded through the said ear, a clamping element carried by the other end of the said base and slidably engaging the frame, and bolt holding means carried by the frame and cooperating with the said jaw and wrench member.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
