FIG. 12 is the same as FIG. 4 with the wedge in place to hold the bracket in place, and
FIG. 13 is a partly sectional top view on the lines 13-13 of FIG. 12.
In the form of the invention shown in FIG. 1, the wrench device or brace includes a base 1 in which is suitably formed an internally threaded hub 2. In the hub 2 is threaded the lower end of a post 3 which in the present form is a pipe. On the top or" the post 3 is formed a handle grip or loop 4 to facilitate the carrying of the unit into suitable position relatively to the wheel.
A cylindrical bracket 6 is slidable on the exterior of the post 3. This cylindrical bracket 6 has a plurality, in this illustration three, holes 7 through opposite sides thereof capable of alignment with transverse holes 8 across the.
post 3. The bracket 6 can be raised or lowered to a desired height and then a pin 9 is inserted through the respective registering holes '7 and 8 to secure and hold the bracket 6 in adjusted position.
A reversible wrench device 11 can be suitably journailed in the bracket 6 in the aligned position so as to engage selectively either the hexagonal nut 12 hearing against the outer wheel 15 of a double wheel truck or bus, or the square or rectangular end 13 of a combination bolt and aninner nut 14, which latter threadedly engages a drum bolt 16 for clamping the inner wheel 17 in place. In the specific form in FIGS. 1 to 5 a reversed channel or hub 18 is welded or integrally formed on one side of the cylindrical bracket 6 so as to form a cavity 19 therein.
On one side of this channel hub 13 is formed a boss 21- through which extends a hole for the insertion of the stub shaft 22. -A cotter pin 23 or the like on the stub shaft 22. shaft 22 in position inside of the cavity 19 retains the stub but permits its rotation. On the outer end of thestub r shaft 22 is integrally formed a hexagonal nut 24 corrcsponding in shape and size to the usual nut 12 which holds outer Wheel 15 in position. From this hexagonal integral nut 24 extends a nose 26 of rectangular cross-section corresponding generally in dimensions and shape to the square or rectangular end of the inner nut 14.
The wrenching device 11 includes a wrench bar 27 of rectangular cross-section, on one end of which is inte-. grally welded a socket 28, in this illustration, of rectan-.
gular cross-section fitting over the nose 26 or bolt end 13.
' On the other end of the wrench bar 27 is fitted the hub 29 of a hexagonal socket wrench 31 which is held in position by a suitable ball catch 32 inside of the hub 29 engaging a dent 33 on the bar 27. Either end may be selectively engaged with the respective nut 24 and nose 26 on the stub shaft 22 as heretofore described.
The Wrench bar 27 may be rotated in any suitable manner. 1n the present illustration a ratchet wheel 34 is slidable on the rectangular wrench bar 27. A ratchet ring 36 surrounds the ratchet wheel 34 in the usual manner and has on it a pivoted ratchet wheel 34. A handle 39 extends from one side of the ratchet ring 36 whereby the ratchet ring 36 is oscillated so that the pawl engages the ratchet teeth 38 intermittently to apply force to the wrench verse the direction of movement of the ratchet device, the hexagonal socket 31 can be pulled oil the respective end of the wrench bar 27 and then the ratchet device can he slid off at the said end and reversed and replaced on the wrench bar.
In the operation of this device the post 3 is carried and placed opposite the wheel to be demounted or mounted, and the ratchet device 11 is placed in position. Then the pin 9 is removed and the bracket 6 is moved longitudinally on the post 3 until the respective end of the ratchet device 11 is in correct registry with the respective nut 12 on pawl 37 to engage the teeth of the bar 27. To re-.
threaded so as to form a threaded track 44 on which a bracket nut 46 travels when the bar 43 is rotated in the bearing 42. From the bracket nut 46 extends on one side an ear 47 which has therein a suitable circular bearing opening 48to accommodate a wrench bar 49 as shown in FIG. 6. The upper end of the brace bar 43 is provided with a crank 51. This crank 51 in the present form includes a horizontal member 52 extended through a hole 53 transversely across the top of the bar 43 and is held securely in place by nuts 54 on the opposite sides of the bar 43. A vertical handle 56 is adapted to be gripped by a hand for facilitating the rotation of the bar 3.
In operation, this device is placed next to the wheel and then the crank handle 56 is turned so as to rotate the bar 43 until the wrench bar 49 in the bearing 48 is aligned with the respective nut or bolt on the wheel 15. Thereupon force can be applied to the wrench bar 69 for loosening or tightening the nut or bolt in the bus wheel.
In the form of the invention shown in FIGS. 9 to 13 a base or footing 6 1 is provided with a bracket plug 62 welded in a base hole 63 on which plug 62 is fixedly secured a hollow brace bar 6-4. On the top of the brace bar 64 is provided a handle 66 to facilitate the carrying and holding of the brace bar 64. Along one side of the brace bar 64 is formed fixedly a rack rail 67 longitudinal with respect to the bar 66. A travelling bracket 68 has a generally rectangular interior to embrace and straddle the bar 64.
A rack anchor 69 is formed on one side of the bracket interior and has teeth adapted to engage the teeth of the rack rail 67. The rectangular interior opening in the bracket 68 leaves a space 72 at the rack anchor 69 so that the bracket 68 can be pulled laterally so as to pull the rack anchor 69 away from the teeth of the rack rail 67 and allow longitudinal adjustment along the bar 64. From the same side of the bracket 66 where the rack anchor 69 is, extends an ear 73 with a bearing opening 74 therein to accommodate the wrench bar 49 heretofore mentioned.
A hanger chock 76 is adapted to be pushed into the interior of the bracket 68 so as to pull the rack anchor 69 into engagement with a rack rail 67 and prevent the disengagement of the same. The upper portion of the hanger chock 76 is bent away from the bar 64 to facilitate this manipulation.
In the operation of this latter device the unit is carried by itscarrying handle 66 to the wheel 15 and then the Wrench bar 49 is aligned with the respective nut or bolt by pulling out the hanger chock 76 and then sliding the bracket 68 to the desired height and then inserting the hanger chock 76 to hold the bracket 68 at the adjusted height.
The wrench bar 49 heretofore mentioned is adapted for selective connection with either the outer hexagonal nuts 12 or with the rectangular ends 13 of the inner bolt nuts 14 on certain types of dual truck wheels or the like. The wrench bar 49, as shown on FIG. 6, has on one end a hexagonal nut 81 intergrally formed therewith, which is generally of the same size as the usual nuts 12 on such wheels. Out of the center of this integral nut 81 extends outwardly a nose 82 of generally rectangular cross-section which corresponds to the usual square end 13 of the inner nut 14 utilized, for instance, in dual wheels of buses. A reversible socket 83 is provided for use this wrench bar 49. The socket 83 has in one end a hexagonal socket 84 fitting over the nut 12 and in its other end a rectangular Al socket 86 which fits over the rectangular nose $2 or the respective end 13 of the inner bolt nut The wrench bar 49 rotatably fits into the bearing opening 48 of the device shown in NOS. 6 to 8 or into the bearing opening 74 of the device shown in FIGS. 9 to 11 and. is extended through said bearings and is held there horizontally. On the outer end of the wrench bar 49 is provided a suitable nose 87 engageable by any suitable lever or hand wheel 38 as shown in FIG 6.
The wrench bar 49 is in the respective bearing 48 or 74 when the respective brackets 46 or 63 are adjusted so that the socket Wrench 83 on the end of the bar 49 is in horizontal registry and engagement with the respective nut or inner nut of the wheel. Then force is applied by the hand wheel 88 or the like for turning the bar 49, which is firmly braced in my device, for loosening or tightening the respective outer nuts l2. Thereafter in order to loosen the inner nuts 14 the socket 83 is simply reversed and in the'sarne single adjustment of the whole device the end of the inner nut 14 can be also engaged and loosened in practically the same operation.
The device is simple in structure and operation and is eminently adapted for its purposes to facilitate the loosening or tightening of the nuts or bolts in large vehicles such as single or double wheels for buses and the like.
