TURN-TABLE.

SPECIFICATION forming part of Letters Patent No. 624,769, dated May 9, 1899.

Application filed August 10, 1 89 8.

T0 at whom it may concern.-

Be it known that I, MILO N. EDWARDS, of Glenwood Springs, in the county of Garfield and State of Colorado, have invented certain new and useful Improvements in Turn-Tables and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements in dumping or tilting turn-tables for cars, wagons, and other vehicles.

The primary object of the invention is to provide a strong, durable, and simply-constructed turn-table capable of being moved horizontally into any desired position and tilted so as to dump from a car or wagon thereon the contents of such caror wagon into another car or other receptacle on a lower plane or it may be onto another platform.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims. i

In the accompanying drawings, Figure 1 is a plan view with parts shown in dotted lines and parts broken away. Fig. 2 isa cross-sectional view on line 2 2, Fig. 1. Fig. 3 is a plan view with the tilting platform and the supports for its pivot-rod removed. Figs. 4.- and 5 are enlarged detail views. 1

Referring to the drawings, A designates a stationary platform, which is shown as being in circular form, and a a circularly-arranged rail mounted on said platform.

B designates a rotary carrier comprising four bars I), radiating from a common center and having wheels I) on their outer ends movable on rail a. The bars I), which are preferably square in cross-section save at their outer ends, which are provided with journals for the wheels Z), are at their inner ends held firmly between upper and lower plates 12 by means of transverse bolts 19 Above these bars I) are arranged two parallel beams 6 each beam resting on two of said bars, said bars and beams being secured together by U-bolts b as shown in Fig. 4. Above one of the beams b is located an upper horizontally-disposed bar I), which is supported by posts I)", extending upwardly from said beam. These posts Serial No. 688,301. (No model.)

their lower ends to the other beamfb.

O O designate uprights secured at their ends to the beams b upon which they are positioned adjacent to the braces 11 Each of these uprights has an inclined ortaperedportion (Z, constituting an abutment.

D designates a rectangular platform composed of spaced-apart beams d and flooring (1 The several beams are united by tie-rods d passed therethrough and also through the spacing-blocks (1 Extended centrally through the beam d is a transverse rod E, the ends of which restin bearings e, mountedon uprights O, positioned adjacent to the upper ends of the inclined abutments. At the lower ends of these inclined portions are jacks F, designed to engage the overhanging portion of platform D, so as to hold the latter in its normal horizontal position-that is, resting upon the cross-bar b, which forms a stop to limit the downward movement of the platform when returned to a horizontal position. Each of these jacks consists of an arm hinged at its lower end to a projection f, bolted to the lower end of the inclined abutment d of upright 0. Each of these arms is capable of being turned outward on its hinge, as shown in dotted lines, Fig. 5.

In practice the vehicle to be unloaded is positioned on the platform D, and a chain G is passed through the rear wheels thereof, and

hooks g on its ends are made to engage short chains g, permanently secured to platform D. Thereupon the jacks F are forced outward from beneath the overhanging portion of platform D and the latter will then turn on its pivot-rod E into the position indicated in dotted lines, Fig. 2, portions of the end beams d resting against the abutments formed by uprights 0. Thus the contents of the vehicle are dumped into a car or other receptacle located on a lower plane than the platform D. It will be understood, of course, that my improved turn-table is located adjacent to some elevated point or platform, so that a vehicle can be readily pushed onto platform D whenthe latter occupies a horizontal position.

From what has been said it will be seen that the turn-table can be rotated to any de-,

sired point either to receive a vehicle thereon or to direct the point of discharge of the contents of thelatt-er, and that this discharge is effected by removing the jacks from beneath the overhangingportion of said platform, allowing the latter to tilt, so as to rest against the inclined abutments.

A turn-table thus constructed is strong-and durable, and being composed of but few parts is not liable to readily get out of order or be i deranged.

I claim as my invention 1. The herein-described turntable-comprising a rotary carrier having uprights formed with inclined abutments, a cross-bar between said uprights, a platform, a cross-rod there-' .in g Witnesses.

uprights, a platform centrally pivoted on said uprights adjacent to the said abut-.ments, and

to engage the overhanging portion of said platform, substantially as set forth.

3. The herein-describedturn-table comprising the rotary carrierhaving radiating bars, wheels on the outer ends of said bars, plates between which the inner ends of said bars are secured, two beams secured on said bars, uprights mounted on said beams having inclined abutments, a .platfor-m,-a cross-rod therefor having its bearin gs on said uprights adjacent to the upper ends of said abutments, and arms'hinged to said abutments so as to open outward therefrom, saidarms beingdesigned to engage the overhanging portion of said platform, substantially :as setforth.
