One of the important objects of the present invention is to provide a wrench machine of the above mentioned character which will save considerable time and labor in applying or removing nuts, the nuts engaging the wrench being operated by a suitable power plant.

A further object is to provide a mechanism of the above mentioned character which can be used for othenpurposcs such as for rotating drills when boring, or supporting in turning the screw driver or so forth.

I A further object is to rovide a machine of the above mentioned 0 aracter which includes a driven shaft capable of rotation in either direction and at any desired speed, a flexible drive being detachably and operatively connected with either end of the driven shaft, said flexible shaft having connection at its other end with the tool supporting means for actuating the same.

A further object is to provide a wrench machine of the above mentioned character which is simple in construction, inexpensive,

strong and durable and further well adapted to the purposes for which it is designed.

Other objects and advantages will become apparent during the course of the following description.

Figure 9 is a sectional view taken approximately on the line 99 of Figure 1, and

Figure 10 is a sectional view taken approximately on the line 10-10 of Figure 1.

In the drawings wherein for the purpose of lllustration is shown a preferred embodiment of my invention, the numeral 1 designates a substantially rectangular shaped frame that is supported at its rear end on the axle 2 on theends of which are mounted the ground engaging wheels 3.

A steering wheel 4 is arran ed beneath the forward end portion of the rame as shown 1n Figure 2. A handle 5 is connected to the forward end of the frame to provide a tongue whereby the machine may be moved from place to place. An electric motor 6 of any conventional construction is supported on the rear end of the frame 1 on suitable cross bars 7.

Additional cross bars 8 extend transversely between the sides of the intermediate portion of the frame and suitable bearings 9 are arg0 ranged on the upper faces of the intermediate cross bars to which is journaled the lon gitudinally extending driven shaft 10 that has connection at its rear end with the drive shaft 11 of the motor 6 through the medium of asuits5 -able coupling 12 as clearly illustrated in Figures 1 and 2 of the drawings.

A relatively large disc 13 is carried by the forward end of the driven shaft 10-for *rotation therewith, the front face of the disc 00 being smooth to provide a driving face.

A transverse shaft 14 has its ends journaled through suitable bearings 15 secured on the upper faces of the opposed side of the forward end portion of the frame and these bearing units 15 are capable of longitudinal slidable movement on the frame as is obvious from the construction disclosed in Figure 1. The ends of the transverse shaft 14 project beyond the outer sides of the respective bearings and are formed with squared projections 16 as is clearly illustrated in Figure, 4 and for a purpose to be presently described in detail.. V V

A collar 18 is secured on the shaft 14 inwardly of each end thereof for disposition against the inner side of the respective bearings to prevent slidable movement of the shaft 14.

Splined on the driven transverse shaft 14 is the wheel or ring 19 that has its outer peripheral face coveredwith a band 20 that frictionally engages with the front face of the disk 13 to provide a frictional driving connection between the drive shaft 10 and the driven shaft 14.

A sleeve or collar 21 is formed on one side of the ring or wheel 19 with which is operatively connected a yoke 22 formed on the rear end of its handle 23 that extends forwardly and terminates in a collar 24 that is splined on a counter shaft 25 that also extends transversely across the top of the frame 1 forwardly of the transverse shaft 14, the ends of the shaft 25 being journaled for rockable movement within suitable bearings shown at 26. A sleeve 27 is also splined on the counter shaft 25 and has a handle 28 extending forwardly therefrom.

This sleeve engages with one side of the collar 24 as shown in Figure 1 so that when the handle 28 is pulled along the counter shaft 25, the ring or wheel 19 will also be pulled along its shaft 14.

As shown in Figure 1, the wheel or ring 19 is located at the approximate center of the driving disc 13 thereby causing the parts t be disposed in neutral position.

When the wheel or ring is moved in one direction and is in engagement with the disc 13, said shaft 14 will be driven in one direction. Obviously by moving the ring or wheel 19 in the other direction, the shaft 14 will be caused to rotate inthe opposite direction.

Also the movement of the ring or wheel 19 toward the outer peripheral edge of the disk 13 will increase the' speed at which the driven shaft 14 is driven. For the purpose of moving the ring or wheel 19 into and out of engagement with the front face of the driving disc 13, there is provided at each end of the counter shaft 25, a relatively short arm 29 to which is pivotally connected the forward end of the link 30, the rear end of each link being operatively connected to the respective longitudinally slidable bearing unit 15 as at 31 with reference more particularly to Figures 1 and 2 of the drawings.

By swinging the handle 28 in a vertical plane, the counter shaft 25 will be rocked causing similar movement to be imparted to the arms 29 and asthese arms are operatively connected to the longitudinally slidable bearing units, said bearing units which support thetransversely disposed driven shaft 14 will move along the upper faces of the respective sides of the frame whereby, as stated above, the spring or wheel 19 may be disposed in an operative position for 24 and the sleeve 27 and it will be observed that said collar is detachably secured on a reduced portion of the sleeve and is held in position thereon by means of a nut 32 threaded on an externally threaded extension formed on the outer end of the reduced portion 33 of said sleeve.

A hollow handle 34 has formed on one end thereof a casing forming extensions 35 in which is arranged for rotation the nut engaging socket 36, the top and bottom faces of the casing forming'extension being open to accommodate the respective end of the socket as shown very clearly in Figure 6.

The nut engaging socket is formed on its outer side at the intermediate portion thereof with the worm gear 37 with which cooperates the worm screw 38 secured on the forward end of a flexible driving shaft 39 and for disposition within the outer end portion of the hollow handle 34.

This flexible shaft drive 39 consists of a plurality of interconnected links shown at 40 in Figure 8, suitable clamps 41 being associated with each link to normally close the same and prevent the displacement of the adjacent links therefrom. A hand controlled clutch unitdenoted generally by the reference character 42 is associated with the forward end of the driving chain 39 and the worm screw 38 and this clutch controlled unit extends through an opening formed in the. handle 34. I

In Figure 10, there is shown in detail the manner in which the clutch operatively connects the worm screw 38 with the forward end of the flexible drive unit 39, the parts being shown in their operative position.

The other end of the flexible drive means has associated therewith a socket 43 for detachable association with either squared end 16 of the driven shaft 14 and a flexible conduit 44 is arranged over the chain 39.

A coupling 45 is associated with one end of the housing or conduit 44 for detachable engagement with a threaded extension 46 formed on the outer side of each bearing unit around the projecting end of the shaft 14 and this is clearly shown in Figure 4.

The other end of the conduit is connected to the rear end of the handle 34 in any suitable manner. When the parts are connected in the manner shown in Figure 1, it is readily obvious that when the motor 6 is in operation and the ring or wheel 19 is in engagement with the disk 13, rotary motion will be imparted to the flexible drive chain 39 which in turn will rotate the socket 36 and when the latter is placed over a nut, the nut will be turned either to loosen or tighten the same in a quick and efficient manner.

The machine when used as a wrench for tightening or loosening will save considerable time and labor and by reason of the flexible drive shaft, nuts can be reached that are ordinarily inaccessible with ordinary type of wrenches.

By replacing the unit 36, with other implements, the machine may be used for various purposes such as for performing operations or in fact wherever it is necessary to quickly and efficiently rotate an element of a small nature or size.

The parts of my machine are so constructed as to permit the same to be readily and easily actuated and furthermore the machine is of a portable nature thus permitting the same to be moved from place to place.

A machine of this character will not only be strong and durable but at all times efficient and reliable in its operation.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invent-ion and the scope of the appended claims.
