LOADING ELEVATOR.

LOADING-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 432,637, dated July 22, 1890.

Application filed April 4, 1890- Serial No. 16,610. (No model.)

tions, arrangements, and combinations, hereinafter fully described, and specifically pointed out in the claims.

The object of my invention is to provide a simple and effective elevator of this class which is adapted to be self-supporting and adjustable to anysuitable inclination, thereby specially adapting it for the loading of ships.

Referring to the accompanying drawing for a more complete explanation of my invention, the figure is a perspective view of my device. 1

A is a wheeled frame or truck, to which is pivoted at b a swinging platform or turntable B,which carries the donkey-engine O, of which 0 may represent the winding-drum. This turntable or platform has its rear end fitted in a grooved guide a on the wheeled frame, and it is fixed in any position to which it may be turned by means of a pin or pins Z) dropped down through holes in its rear end and entering corresponding holes in the frame below. Hinged to the forward end of this turn-table is the elevator-frame D. This carries in its upper end a guide-drum (Z and in its lower end a driving-drum (1, while throughout its length on its upper surface it carries a series of supporting-rollers (P.

E is an endless elevator belt provided with suitable cross bars or slats c. This belt is mounted in the elevator-frame with its ends passing over the drums cl and d and supported in its course by the rollers (1 Travel is imparted to the elevator-belt by means of a belt F, which extends from a pol ley c on the winding-drum c of the engine to a pulley d on the lower or driving drum d.

The elevator-frame D may be raised or lowered to any inclination, turning about the hinge at its lower end, and it is held to its inclination by the block and tackle, (represented by G,) one end of which is connected with stanehions g on the upper end of the elevatorframe and the other end is connected with a rigid stanchion b on the turn-table. The fall of the tackle extends down to a cross-cleat b on the stanchion, whereby it is held. The stanchion itself is held rigid by the guys I), as shown.

Hinged to the upper end of the elevatorframe D is the discharge chute or spout H, the inclination of which is adjusted by the ropes h.

In the lower portion of the elevator-frame D, just below the elevator-belt, near its lower end, are rollers I, set close together, the purpose of which is to avoid wear and injury to the belt by the constant throwing of the goods upon it at this end. These resisting-rollers are mounted at their ends in plates of metal 2' on the inner surface of the sides of the frame D, so that they will not wear out readily. At this p0int,where the goods are thrown upon the belt, there is a constant and decided wear, and it becomes necessary to overcome this by the use of the closely-set rollers.

The operation of the elevator is as follows: It will be observed that it is self-supp-orting, and therein it differs from those elevators for loading ships, the upper ends of which are adapted to be fitted upon and secured to the ships rail. Elevators of this class are defective in that the ship is always in motion, and

is closer or nearer to the wharf at different times, and is continuallymoving to and from it, so that the elevator itself is on the move and it is difficult to load it. There is also the disadvantage in these elevators of getting loose and falling into the water. In my elevator these disadvantages are obviated by carrying the whole device positively by the Wheeled frame A, so that it is wholly independent of the ship and stands alone. It may be set to an inclination to accommodate the height of the ship or the position of the discharge, and may be there held firmly and rigidly. It may also be turned to any angle to suit the circumstances of each case by turning the platform or turn-table B on the wheeled frame.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A loading-elevator consisting of a wheeled framehaving the fixed curved guide a at one end, a platform pivotally mounted on said frame and having its forward end adjustably held in said guide, a power device carried by said platform, a frame hinged to the rear of the platform having a traveling belt mounted on rollers therein, a block and tackle for adjusting and holding said hinged frame, and a connection from the power device to one of the belt-rollers, whereby the belt is operated, substantially as herein described.

2. A loading elevator consisting of the wheeled frame A, the pivoted platform or turn-table B on said frame, and the pins at the rear thereof for holding said platform or turn-table in the position to which it is adjusted, the engine and power mechanism on said platform and the stanchion thereon, the frame D, hinged to the forward end of the platform or turn-table and having the drumsend of the frame, substantially as herein described.

In witness whereof I have hereunto set my hand.
