Application January 25, 1945, Serial No. 574,545
This invention relates to a generator attachment for tractors. tractors are not provided with electric generating equipment, and in some cases there are no projecting shafts or pulleys which can be eifectually utilized for driving a generator.
The principal object of this invention is'to provide a neat, simple, and highly emcient attachment which can be applied to a standard tractor, more particularly kof the Caterpillar type, and which will support a standard automotive generator and transmit power thereto from the engine of the tractor.
Another object of the invention is to sc construct the attachment thatit can be quickly and easily applied to the tractor engine without requiring any changes therein or machine work thereon, and which will not interfere in any way with the normal operation of the engine.
Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efllciency. These will become more apparent from the following description.
In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.
In the drawing:
Fig. 1 is a side view of the improved attachment, partially in section, illustrating in broken line the relative position on the co-acting portions of a tractor engine;
Fig. 2 is a plan view of the improved attachment; and
Fig. 3 is a front view thereof.
Theinvention could be used on many types of tractors. It is more particularly designed for a Caterpillar tractor. On such tractors the fan and water pump shaft are the only shafts that are open to the outside ofthe engine. These shafts, however, rotate in the wrong direction, are inconvenient for use in driving a generator, and are in such positions that no available space is' allowed for the generator. The shaft of the Water pump of the tractor, however, although entirely enclosed, rotates in the proper direction and is in the proper position for this use. The shaft is provided with a drive gear which is accessible by removing a cover plate. This improved attachment is designed to replace the said cover plate and to make use of the drive gear for power purposes.
In the drawing, the water pumpv is indicated 55 the Many \of the standard v 3 Claims. I Cl. 74-11) in broken line at I, the water pump shaft at II, the water pump drive gear at I2, and the water pump drive housing at I3.
They improved attachment is designed for mounting on the water pump gear housing I3 of the engine of the tractor. To apply this attachment thereto, the standard cover plate is removed and a gear case I4 is secured in place of the cover plate. The case is provided with a base flange I5 which overlaps the frame of the opening in the gear box housing I3, and is secured thereto by means of suitable cap screws I8, which may be the screws that formerly held the cover plate in place thereon.
The gear case Il is provided with bearings Il in its opposite faces, in which a gear shaft I8 is journalled. A drive gear I9 is keyed or otherwise secured on the shaft I8 within the case Il. This `gear is of the proper diameter, t'ype. and shape to mesh with the pump gear I2 when the case I4 is secured in piace on the housing I3. The shaft I8 terminates on the exterior of the gear case I4 in a V-belt pulley 20.
A U-shaped generator bracket 2i is formed on the case I4. The two arms of the bracket 2| are drilled to receive hinge bolts 22, by means of which a standard automotive electrical generator 23 is hingedly mounted. The generator is provided with end plates 24, both of which are provided with an ear 25 which are mounted on thel hinge bolts 22. The front end plate 24 is provided with a second ear 2t terminating in va clamp bolt 21 having a clamping nut 28. The clamp bolt 21 rides in a longitudinal slot 29 in a hinged brace member 30, and can be clamped in any desired position along the slot 29 by means of the nut 28. 'I'he brace member 30 is mounted on a hinge bolt 3| extending through a projecting lug 32 on the gear case It.
The generator 23 is provided withthe usual generator shaft 33 upon which a second V-belt sheave 34 is mounted. An endless V-belt 35 is trained around the V-belt sheaves 2B and 34. The v-beit can be adjusted by varying the position of the clamp bolt 2l in the slot 29 to obtain the desired tension therein.
To install the device it is only necessary to remove the cover plate from the pump housing I3 and setQthe baseiiange I5 thereon. The `cap screws are then tightened and the device is ready for operation.
It can be readily seen that as the gear I2 rotates to drive the pump III, it will .also drive the gear I9 and. through the medium of the belt 35,
generator 23.
WhileI a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit o! the invention.
Having thus described the invention, what is claimed and desired secured by Letters Patent 1. A combined power takeoff device and generator support for internal combustion engines comprising; a gear shaft; a driven gear mounted on said shaft; a gear housing about said gear; bearings in the opposite lsides of said housing supporting said shaft, the lower portion of said housing being open below said bearings to allow said gear to project downwardly therefrom; an attachment means on said housing at each side of the open portion thereof; a belt drive sheave mounted on said shaft exteriorly of said housing; a generatorwsupporting bracket mounted on said housing; and an endless belt extending from said drive sheave to driving engagement with the generator.
2. A combined power takeoff device and generator support for internal combustion engines comprising: a gear shaft; a driven gear mounted on said shaft; a gear housing about said gear; bearings in the opposite sides of said housing supporting said shaft, the lower portion of -said housing being open below said bearings to allow said gear to project downwardly therefrom; an attachment means on said housing at each side of the open portion thereof; a belt drive sheave mounted on said shaft exteriorly of said housing; a U-shaped generator bracket secured to and extending parallel to said shaft; means for pivotally mounting one side of a generator at each extremity of said bracket; a brace member hinged to said housing; means for adjustably securing said brace member to the other side of said generator: and an endless belt transmitting power from said belt drive sheave to the generator.
