HOISTING DEVICE.

Specification of Letters Patent.

Patented Nov. 18, 1913.

. Application filed February 13, 1913. Serial No. 748,210.

To all whom it may concern:

Be it known that I, JERRY A. VAUGHN, a citizen of the United States, residing at Montello, in the county of Marquette and State of Wisconsin, have invented certain new and useful Improvements in Hoisting Devices, of which the following is a specification.

My invention relates to the class of hoisting devices and more particularly to such a device adapted for use in connection with wagons or other vehicles.

The primary object of the invention contemplates the provision of a specially devised hoisting device wherein loading and unloading of heavy articles upon vehicles is greatly facilitated, such device being so arranged upon the vehicle as to evenly distribute the weight of the article acted upon, regardless of its position. I

A further object of the invention resides in the provision of suitable mechanism carried solely by the vehicle at all times and whereby, during one operation of the hoisting element, the article operated upon may be successfully hoisted to a desired elevation, and then conveyed to a position above the floor of the vehicle.

A still further object of the invention is to provide mechanism of this character which can be quickly adjusted to the desired working position, and which can be used effectively for the purpose of placing the article hoisted, upon the floor of the vehicle as desired.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claims which are alppended hereto and form a part of this app cation.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of a device constructed in accordance with my invention. Fig. 2 is a section on line 2-2 of Fig.

1, and Fig. 3 is a section on line 33 of Fig. 1.

Proceeding now to the description of the drawing, wherein is illustrated the preferred form of my invention the numeral 1 designates a wagon upon which the hoisting device is mounted, the said Wagon being provided with standards 2 for supporting a seat 3. While the device herein shown is preferably mounted upon the wagon as illustrated in Fig. 1 of the drawings, the same may be mounted upon anytype of vehicle whatsoever, as the particular structure of the vehicle has nothing whatsoever to do with the invention.

Upon the under side of the wagon floor and secured thereto through the medium of a plurality of bolts 4, I provide a pair of rack bars 5 arranged in parallel spaced rela' tion upon the under side of the vehicle, the said bars being disposed in the same plane and to extend longitudinally of the vehicle, and if desired formed either in one piece or connected through the medium of a plate through which the bolts 4 extend, thereby supporting the bars 5 in proper place, one near each side of the vehicle. Adjustably mounted upon the said rack bars by means of a transversely extending bar 7, area pair of upwardly extending parallel beams 8, the said bar connecting the lower extremities of the said beams and normally fitting within the notches of the said bars 5. The said beams 8 may be of any desired length, and terminate at their upper extremity in a cross beam 9 from which depends a double pulley block 10, the purpose of which will hereinafter fully appear.

Between the standards 2 and beneath the drivers seat a pair of drums 11 and 12 are mounted, the upper drum 11 having a gear wheel 13 upon one end thereof and a ratchet wheel 14 upon the opposite end thereof, while the lower drum 12 is likewise provided with a similar gear wheel 15 and a duplicate ratchet wheel 16, motion being imparted from the gear 13 to the gear 15 or vice versa by means of a pinion 17 interposed therebetween. Pawls 18 are pivoted as at 19 to one of the standards 2 and normally engage the ratchet wheels 14 and 16 to prevent unwinding of the drums during the hoisting operation. In the preferred form but one crank handle 20 is necessary in the operation of the drums, as the gears and pinion are adapted to impart motion from one to the other of the drums simultaneously.

A rope 21 is secured to the lower drum 12 and extends over one of the pulleys in the block 10 from which point, it depends to a second pulley block 22 where it pages over one of the pulleys provided therein. The rope 21 after passing over the pulley of the block 22 extends to the other pulley of the block 10 from which point it a ain depends to a point 23 where it is secure in any suitable manner to the block 22. Any form of grapple or hook 24 may be employed in connection with the block 22 for the purpose of afiixing or attaching the article to be acted upon. The ropes 24 are secured to the drum 11, one near each end thereof and extend substantially parallel to a point 25 where they are secured in any suitable manner to the upper extremities of the beams 8 so as to swing the latter according to the rotation of the drum.

In operation, the article to be acted upon is first secured to the hook 24, the beams 8 having been previously adjusted upon the rack bar 5 as desired, whereupon the crank 20 is turned for imparting motion to the drums 11 and 12. By such turning of the crank the ropes 21 and 24 are drawn taut, the rope 21 lifting the weight from the ground or its support to the desired height, while the rope 24 swings the beams 8 upon the bar 7, which acts as a fulcrum, until the said beams support the weight above the vehicle floor in the desired position. The paw'ls 18 are then disengaged from the ratchet wheels 14 and 16 and the weightis deposited upon the floor of the vehicle in the manner and place desired.

In practical application the pinion 17 may be eliminated and the spindles upon which the drums are mounted, provided with angular extensions upon which the crank 20 is adapted to fit. This operation will necessitate a separate winding of each drum thereby causing the operation of hoisting the weight to be entirely independent of the operation for swinging the beams into proper position.

It will be seen from the above taken in connection with the accompanying drawings that by shifting the rod 7 upon the rack 5 as desired, proper adjustment of the beams 8 is permitted; that the article acted upon may be placed within the vehicle at any point desired; such action being entirely controlled by the rotation of the upper drum 11; and that the lifting or hoisting of the article is controlled by the rotation of the lower drum 12.

While I have shown and described my invention as applied to a wagon, I desire that the utilization of the device shall not be limited to such, as the mechanism comprising my invention may be readily applied to any supporting structure whatsoever.

It will be understood that the above description and the accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in the details of construction, proportion and arrangement of parts may be made within the scope of the appended claims and without sacrificing any of the advantages of m invention.

Having thus fully escribed my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a hoisting device, the combination of a supporting structure, parallel rack bars mounted in the same plane upon the said structure, upwardly extending beams longitudinally adjustable and pivoted to swing vertically upon said bars, and means including a pair of drums carried by the said structure and connected to the said beams for swinging the latter into adjusted position, as and for the purpose set forth.
