To all whom it may concern.-

Be it known that l, `CHARLES W. SPENGLER, a citizen of the United States, residing at .l effersonville,'in the county of Fayette and State of Ohio, have invented a new and useful Wrench-Operating Mechanism, of which the following is a specification.

This invention relates to Wrench-operating mechanism particularly adapted for use in turning nuts'on boltssuch 'as are used to sea device to eject the nuts from the wrench.

' and. particularly pointed out in the claims.

` together by bolts 2.

In the drawings, Figure 1 is a side elevation of my improved wrench-operating mechanism, the casing being in section, showing one form of the connecting devices between the operating-shaft and. the wrench carrying shaft. Fig. 2 is an end view. Fig. 3 is a similar View looking at the other end of the device, the casing being broken awayl to show the gearing. Fig. 4 is a view similar to Fig. 1, showing another form of connecting device between the operating-shaft and the wrenchcarrying shaft, the connecting device being partly broken" away. Fig. 5is a perspective view of the connecting device for the shafts.

Fig. 6 is a longitudinal section through the wrench-head, showing the manner of mounting the nut-ejector. Fig. 7 is a perspective View of the ejector detached.

Similar reference-numerals indicate similarparts in the several figures.

Referring to Figs. 1, 2, and 3, 1 indicates a hollow casing formed in two sections separable on a vertical line, detachably connected The casing is provided withtalining openings 3 in its opposite sides to receive and form bearings for the respective hubs 4 and 5 of the gears 6 and 7. The

gear 6 will preferably be of less diameter than 5 5 the gear 7 in order that it may rotate faster. Each hub will preferably have shoulders 8 to engage theinner faces of the casing and prevent longitudinal movement of the hubs inff# The gears 6 and 7 are fast on 6o their bearings.

the hubs and rotate with them. 1 Y

The hubs- 4 and 5 Iare each provided with a longitudinal angular bore 9 to receive, re-

' spectively, the wrench-shaft 10 and the operating-shaft 11, and these shafts are supported in the hubs to slide freely therein, but to have no rotary movement in the hubs.

12 indicates the wrench-head, secured on one "end of the shaft 10 and provided with an angular opening 13 to receive the nut to be 7o turned. If preferred, the wrench-head may be detachably connected to the shaft 10 in order that the head 'may be changed, if necessary, to adapt the device for use with nuts of different sizes. 10 is rounded and provided with an annular groove 14, and this rounded end fits loosely in a socket 15 and is held therein by a setscrew 16, which extends into the annular groove and permits free rotary movement of 8o the shaft in the'socket, but prevents it from being withdrawn therefrom. The corresponding end of the shaft 11 is also rounded and l provided with an annular groove 17, and the rounded end fits loosely in a socket 18, similar to the socket 15, and is held therein by a set screw 19 in a manner similar to that described with reference to thev shaft 10. Each socket is provided with a pair of spaced ears 20 for a purpose which will be referred to hereinafter. 9o

21 indicates an arm,preferably integral with the casing, although it may be secured thereto in any other manner, if preferred, and this arm extends horizontally from the casing. 22

indicates a lever or yoke pivotally connected The other end of the shaft 7 5 The 10o lVhen the yoke is rocked on its pivot, the blocks will slide in the openings 24, and as the sockets are pivotally connected to the blocks the parts will adjust themselves when the yoke is rocked in either direction by the longitudinal movement of the shafts. The opposite end 27 of the shaft ll is shaped to receive an ordinary bit-brace, by means of which the shaft may be turned, or it may be turned by any other suitable device. The casing is provided with a ange 23 at its lower end, through which bolts or screws 29 are adapted to pass to secure the casing to any suitable support.

Referring now to Figs. 5 and G, it will be observed that the parts of the machine are similar to those already described, except as to the form of the ends of the shafts l0 and 1l and the yoke connecting them. In this form each shaft is provided with a ball 30 on its end and a narrow neck portion 3l between the ball and body of the shaft. The yoke is in the form of an open-ended tube, (indicated by 32,) the interior diameter of which is substantially equal to the diameter of the balls 30, which are intended to fit loosely therein. The tube is provided with a slot 33 at one side, extending from end to end and with an outwardlyprojecting flange 34 at each side of the slot. Midway their length the flanges are widened to form the ears 35, which are perforated, as indicated at 3G. The end of the arm 2l projects into the tube between the ears 35, and the pivot-bolt 23 extends through said ears and the arm 2l. The balls 30 are inserted into the tube at its respective ends, and the necks 3l on the shafts will extend through the slot 33 and between the iianges 34, and it is evident that the yoke will be free to adjust itself on the balls 30 when it is rocked on the pin 23 by the horizontal movement of the shaft and that the balls can turn axially in the yoke. The balls 30 form pivotal connections between the lever or yoke and the shafts l0 and 11, and the pivotal connection is adapted to move freely longitudinally of the lever or yoke.

Referring now to Figs. 5 and 6, it will be seen that the nut-ejector comprises arectangular block 37, from opposite sides of which a pair of arms 38 extend rearwardly, the outer ends of these arms being bent to form lateral projections 30. The block 37 is adapted to work loosely in the opening 13, and the arms 3S in grooves 40, in the wrench-head, and the severa-l parts will be so proportioned that when the lateral projections 39 engage the rear end of the wrench-head the front end of the block 37 will be flush with the front end of the head, as shown in Fig. 5.

In operation the wheel will be supported in a horizontal plane in such manner as to enable the wrench l2 to fit over the nuts of the tire-bolts successively, and by turning the shaft ll rotary movement will be imparted through the gears 7 and 6 to the shaft l0 and the wrench-head l2, and it is obvious that this rotary movement may be in either direction to turn the nut on the bolt or turn it off, as desired. Vhen turning the nut on the bolt, the shaft ll will be pushed forward toward the pivoted yoke, and the yoke will thus be rocked on its pivot and move the shaft l0 in the opposite direction, thereby causing the wrench-head to follow up the nut as it is turned onto the bolt. In turning the nut oil the bolt the nut will cause the shaft l0 to grad ually retreat in front of it, and this movement of the shaft will rock the pivoted yoke and move the shaft 1l in the opposite direction. When the nut has been removed from the bolt, the ejector will have been forced rearwardly, and by pulling on the shaft ll the lateral projections 39 will be caused to engage the hub 4, and the ejector will move toward the open end of the wrench-head and eject the nut.

It will be understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim isl. In a wrench-operating mechanism, the combination with an operating-shaft, and a wreneh-carryingshaft both su pported to have rotary and longitudinal movement, of gearing to transmit rotary movement from one shaft to the other, and a lever fulcrumed between its ends and pivotally connected with the shafts, whereby the shafts are simultaneously reciprocated in opposite directions, substantially as described.
