This invention relates to a power take-off adapted for connection with a motor vehicle and hasfor its primary object to provide in a manner as hereinafter set forth, a device of such character which is capable of perform-'- ing a number of operations selectively or'simultaneously.

A further object of the invention is to provide a device of the character aforesaid ineluding a power shaft which may be driven at a variety of speeds and further which may be driven in opposite directions.

A further object of the invention is to provide a device of the character aforesaid which is of simple and sturdy construction, and

comparatively inexpensive to manufacture and install with respect to a motor vehicle.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more particularly described, and shown in the accompanying drawings, but it is to be understood that the description and drawings are to be considered as illustrative rather than limitative.

numeral 1 indicates generally a motor vehicle including a pair of frame members 2 to which are secured a similar pair of frame members 3 for the power take-off indicated generally at 4. The framemembers 2 are secured together by means of suitable cross braces 5 and are further secured by means of braces 6 to the webs 7 connecting the fenders 8 of the vehicle with the frame members 2 thereof.

The power take-off is operated from the crank shaft 9 of the vehicle and is connected therewith by means of a flange 10 on the sleeve 9', the flange 10 being secured by suitable bolts to the fan belt pulley 11 mounted on the crank shaft 9. The sleeve 9 provides a socket 12 of polygonal contour within which is slidably secured the squared end portion 13 of a relatively short shaft 14. Fixedly secured to the forward end of the shaft 14 is' a coupling element 15 including an annular flange 16 formed in its inner -peripheral face with a series of teeth 17. The forward end of the shaft 14 is formed with a socket 18 circular in cross section within which is rotatably mounted a reduced end portion 19 of a shaft 20, the opposite end of which is connected with a clutch shown conventionally at 21 and including a fly wheel 22'. A forward portion of the shaft 20 is of polygonal shape in cross section, and slidably mounted thereon is a collar 22 formed with. a gear 23 adapted to mesh with the teeth 17in the flange 16. The gear 23 is shifted into and out of meshing position with respect to the flange 16 by means of a shifting yoke 24 having a handle portion 25 slidably extending through a bearing 26 carried by a bracket 27. Extending through the bearing 26 is an adjusting screw 28, y means of which the gear 23 may be secured in active or inactlve position as desired.

When the gear 23 is in inactive position, the coupling element 15 rotates about the reduced end portion 19 of the shaft 20, the

shafts

14 and 20 being maintained in alignment by the portion 19.

Extending in parallel relation to the

shafts

14 and 20 is a power shaft 29 which is journaled in suitable bearings 30 carried by the frame members 3. Fixedly mounted on the shaft 29 is a pulley 31 which is connected by means of an endless belt 32 with the fly wheel 22' the outer peripheral face of which is of flat formation in order that the fly wheel may serve as a pulley. Fixedly mounted on the shaft 29 is a pulley 33 for engagement by a suitable belt, not shown, for the purpose of operatin a belt, pum mill or the like.

Extending forwar 1y from the clutch element 21 is a transmission shaft 34 which is provided at one end with a slidable clutch sleeve 35, and the other end of which extends into the housing 36 of a transmission mechanism which may be of any well known type for changing speed or reversing by the manipulation of a shift lever 37. Projecting forwardly from the transmission housing 36 is a power shaft 38 which rotatably extends through a sleeve 39 on an angular bracket 40 mounted on a suitable base 41 and held in position thereon by means of a cap 42 provided with suitable holdfast devices 43. Fixedly mounted on the forward end of the shaft 38 is a pinion 44 which is in mesh with a ring gear 45 fixedly mounted on a shaft 46 for operating a drill or the like. The shaft 46 is provided with a squared outer end portion 47 in order that a suitable chuck, not shown, may be secured thereto. The bracket 40 may be rotated about the shaft 38 to alter the extending direction of the shaft 46 by loosening the holdfast devices 43 and rotating the sleeve 39 Within the seat therefor in the base 41. The shaft 46 extends through a suitable opening 48 in the bracket 40. Formed integrally with the pinion 44 is a sleeve 49 havin a ratchet face 50 for engagement by a cran not shown, if it is desired to start the motor of the vehicle 1 from the ground. A bumper 51 is carried by the forward ends of the frame members 3, the bumper being provided with a retaining collar 52 through which the crank may be rotatably extende Fixedly mounted on the shaft 38 is a sprocket 53 which is operatively connected by means of a chain 54 with a sprocket 55 on a power shaft 56 extending in parallel relation to the shaft 38 and j ournaled in suitable bearings 57 carried by one of the frame mars 3. Fixedly mounted on the power shaft 56 is a second sprocket 58 which is operatively connected by means of a chain 59 with a sprocket 60 on a cylindrical drum 61 rotatably mounted in bearing members 62 mounted on one of the fenders 8. The drum 61 is provided at its forward end with "a pipe vise 63, and arranged in spaced relation to the pipe vise 63 are a plurality of tool hold-v ing members 64 which are rigidly connected with the bearings 62. Suitable pipe or thread cutting dies may be secured by the members 64, and a pipe which it is desired to thread or cut is secured within the vise 63 and rotated with respect to the tools car: ried by the members 64.

The clutch collar 35 may be shifted into and out of operative position by means of a yoke 65 which is. in engagement with the clutch collar and which is fixedly connected with a rotatable rod 66 extending transversely of the device and journaled in suitable bearings 67 carried by the frame members 3. Rotation of the rod 66 swings the yoke 65 in an arc to move the clutch collar 35. The rod 66 is operated by means of a crank 68 fixedly secured thereto and connected by means of a pull rod 69 with the upturned end 70 of a lever 71 pivoted adjacent its upturned end as indicated at 72. The pivot pin 72 extends through a ri id strap 73 and coacts with a suitable bolt 4 for securing the strap 73 to one of the frame members 3. The pivot pin 72 further extends through a segmental ratchet 75 which is fixedly secured to the strap. 73 by means of a suitable bolt 76. A pawl 7 7 is pivotally connected with the lever 71, the pawl being operated by a handle member 78.

It is thought that the many advantages of a power take-off in accordance with this invention will be readily apparent, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the size, shape and arrangement of parts may be resorted to, so long as such changes fall within the scope of the invention as defined in the appended claims.
