ELEVATOR.

Specification of Letters Patent.

Patented Apr. 27, 1920.

To all whom it may concern:

Be it known that I, VA-NDERLYN I-Iowxnn FELT, a citizen of the United States, residing at Kendall, in the county of Orleans and State of New York, have invented certain new and useful Improvements in Elevators, of which the following is a specification.

The object of this invention is to provide a new and improved form of elevator. This and other objects of the invention will be illustrated in the drawings, described in the specification and pointed out in the claim at the end thereof.

In the drawings:

'Figure 1 is a perspective view of my improved elevator.

Fig. 2 is a detail view, showing a modification of the rope gearing thereof.

Fig. 3 is a side elevation of a modification of the elevator.

Fig. 4 is a vertical section on the line 4 4 Fig. 3.

In the drawings, like reference numerals indicate like parts.

In the drawings,,reference numeral 1 indicates one of the uprights and 2 indicates another upright, which uprights are connected at the bottom by the cross bar 3. Connected to the uprights are the bracket members 4 and 5, 6 and 7, which extend rearwardly therefrom. At the rear end these brackets are connected by the bars 8 and 9. The brackets 5 and 7 are also connected by the cross bar 10, which serves to tie the uprights together. Mounted at the top ofeach of the uprights are the straps 11 and 12 in which are mounted the pulleys 13 and 14. Mounted in the bars 8 and 9 is the axle 18 of a drum 15. On the end of the drum is provided the ratchet wheel 16, with which engages the pawl 17 by means of which the movement of the ratchet wheel and the drum in the reverse direction is prevented. The end of the axle 18 is shown projecting at the right. Mounted on the upright 2 is the bracket 19, in which is mounted to rotate the crank 20, which is connected to the axle 18 by means of the universal joint 21. It will be understood that the axis of the crank 20 does not extend in line with the axle 18 but extends forward at an angle thereto so as to provide ample room in which to turn the crank 20 when the elevator is in position for use. It will,

be understood that the elevator is intended fere with the rotation of the crank handle.

except for the angular position of it. These bars 8 and 9 serve as rests which make contact with any supporting object and serve to hold the runways in an upright position. They are preferably located below the top because they are intended'to make contact with a wagon bed or platform of a grader, etc, and the runways must extend above this point to give a margin for-hoisting.

Attached to the drum 15 are the ropes 22 and 23, which pass over the pulleys 13 and 14, and connect to the platform 24. This platform is mounted to travel along the up rights 1 and 2, and is provided with the Ushaped, iron yokes 25 and 26, on which are carried the anti-friction rollers 27 which travel with the yokes and hold the platform in line between the uprights.

By turning a crank 20 the ropes 22 and 23 are wound up on the drum 15 and the platform 24 is lifted to any desired height to which it may be held by means of a pawl and ratchet, while the barrel is being removed.

In order to increase the power of the apparatus, I use a double set of pulleys, in which case the ropes will be attached to the drum at one end and at the other end to the hook 28, one of which is provided on each upright. A pulley 29 will be provided on each yoke around which the rope will pass, the rope then passing over the pulleys at the top of the uprights. In this case I will have a fixed and a moving pulley so that the lifting power of the apparatus 1s doubled.

In Fig. 3 I have shown an improved form of my device in which the elevator is power driven. In this case the ropes are wound on a drum 40 carried on a shaft 41. On this shaft rotates loosely a sleeve 42 which carries a sprocket wheel 43 driven by a chain 44 from a motor 45 which may be either electric or gasolene engine. 7 On the shaft 41 is provided a clutch 46 which is clutch 46 I have provided the yoke 47 which is carried on a bar 48, which bar slides in the sleeve 419 mounted horizontally on the upright 50. Mounted to slide vertically on the upright 50 is the rod 51 supported by the brackets 52 and 58. This rod carries bracket 54: with which the lug 55 carried on the platform makes contact so that it is carried up by the platform. At the lower end of the bar 51 is provided a cam 51A which engages the bar 48 and moves it to the left, opening the clutch and stopping the movement of the elevator when it lifts the rod 51. The platform of the elevator will be held in its raised position by means of the ratchet heretofore described. The bracket 5-1 is adjustable up and down on the rod 51 so that the point at which the platform of the elevator will be stopped may be varied.

The elevator shown in Fig. 3 is mounted on a base 56 supported by casters 57 so that it can be easily moved over the floor. It comprises the uprights 1 and 2 as they are shown in Fig. 1, along which 'the elevator travels and it is also provided with the uprights 58 to which the uprights 1 and 2 are connected by the cross bars 59 and 60.

I claim:

In an elevator, the combination of a pair of runways, a platform adapted to travel between said runways, a rearwardly proj ect: ing bracket provided on said runways to hold said runways away from the wall, a winding drum mounted on said bracket be} hind said runways, a handle connected to said drum and supported angularly thereto on one side of said runways, a pulley carried on top of each of said runways, ropes connected to said platform and passing over said pulleys to said winding drum and guides on said platform to guide said platform on opposite sides of both of said runways.

In testimony whereof I affix my signature.

VANDERLYN HOWARD FELT
