Application led October 6, 1900 l Serial No. 32,233. (No model.)

.To @ZZ whom t may concern: Be it known that I, CAMILLE MEROADER, of Braddock, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Charging Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in whichl Figure 1 is a plan view, partially broken away, showing a preferred form of my apparatus. Fig. 2 is a side elevation of the same, partly in section, showing the receiving-pins in lifted position; and Figs. 3 and Lle are crosssections, on a larger-scale, showing the pins in lowered and raised positions, respectively.

My invention relates to the charging apparatus employed for feeding a plate or pile of plates to a heating-furnace or other apparazo tus, and more particularly to skelp-charging apparatus.

The object of the invention is to simplify and improve the apparatus used for this purpose, to arrange the parts so that a pile of plates may be received upon it and moved into the furnace either as a pile or one by one, to provide automatic mechanism for elevating certain supports to receive the pile in one position of the apparatus and to lower 3o the pile upon the machine `in position for charging, and, further, to simplify and improve the arrangement of .thepushing-bar and its actuating mechanism.

In the drawings I show the charging-ma- 3 5 chine 2 as mounted on end trucks 3 3, hav

ing wheels moving on tracks 4, which extend alongside the furnace to bring the apparatus in registry with the charging-o penings,

The body of the machine consists, essen- 4o tially, of two I-beams 5, secured together by suitable cross-beams 6 and also by castings 7 having vertical holes containing movable pins S. The pins 8 are secured in pairs to crossheads 9, having links 10, connecting them to rock-arms 11,secured toa rock-shaft 12, which extends along that portion of the machine adjacent to the furnace, as shown in Fig. 2. An actuating-lever 13 is secured to the shaft 12 and is provided with a roller 14, which 5o moves Aupon a suitable guideway extending parallel with the tracks and having an inclined cam portion 15, by which thelever is rocked. This cam portion is located at one side of the furnace-openings, so that after its action has lifted the pins 3 into the position shown in Fig. 2 the machine may be brought beneath the depending yokes or hangers 16 of an overhead crane. The arms or hangers of the crane being lowered between the pairs of pins will deposit the pile of plates or skelp 17 upon the pins. As the machinev is then moved back into registry with one of the furnace-openings the roller 14, moving down the camway, will lower the pack upon 'the parallel supporting-plates 13 of the machine. These supporting -plates are spaced apart, and between and beneath them a trough is formed by a pair of angle-irons 19, secured in recesses in the castings 7, with their baseflanges extending toward each other and spaced slightly apart. A track is thus formed for a sprocket-chain 20, which extends over end sprocket-wheels 21, and in the lower part of its path moves over a guide or track 22, consisting of a channel with its flanges projecting upwardly and supported by suitable hangers 23. The shaft 2,4 of the rear sprocket- -wheel is provided with a gear-wheel 25, intermeshing with a reducing-gear 26, driven by an electric motor 27, carried upon a rear extension of the machine.4 The push-rod. 28 is pivoted to a truck 29, having wheels 30, movable on the I-beams 5 of the machine, which form a track therefor. The truck is secured to the chain by meansof the depending bolt connection 31, the forward end of the bar being supported by a butt-joint at its other end. The bar is arranged to receive a fork or other pushing device.

The machine may be moved along the tracks by any suitable mechanism, and I show the rear truck as extended and receivingl an electric motor 32,- whose shaft is provided with a worm 33, intermeshing with a'worm- Wheel 34 upon the shaft ofone of the sets of wheels.

The machine is provided at one side with laterally-projecting supports or brackets 35, upon which a pile of plates may be deposited instead of upon the pins when it is desired to feed the plates one by one.

In operating the machine motor 32 is actuated to move the machine to' one side of the furnace, the roller 14 lifting the receiving- IOO pins into the position shown in Fig. 4. The pile is then lowered onto the pins from an overhead crane, as indicated in dotted lines, and as the machine is moved back after the removal of the crane the pins are automatically lowered, the pile of skelp then resting upon the supporting-plates 1S. AThe machine being stopped in front of the charging-openings, the motor 27 is actuated to force forward the push-bar, which contacts with the rear ends of the plates and pushes the pile into the furnace. If it is desired to feed the skelp plates one by one, the pile is deposited on the lateral brackets 35 and each plate is drawn sidewise upon the supporting-plates IS and the pusher actuated to force these plates into the furnace or to a scarIing-machine or other apparatus, as desired.

The advantages of my invention result from the forming of the machine in such manner that a pile of plates may be deposited upon the machine ready for pushing into the furnace without being moved sidewise by the operator, and, further, from the use of the vertically-movable pins or supports, which are automatically projected and retracted during the movements of the table, and also from the location of the pushing truck or car,- riage, which is above the chain, giving easy access and simple construction.

Many changes maybe made in the form and arrangement of the parts without departing from my invention.

I claiml. A charging-machine comprising a laterallyn1ovable carriage having vertically-movable supports arranged to receive a pile of plates, and mechanism for lowering the supports to deposit the pile upon the machine; substantially as described.

2. A laterally-movable charging-machine havin g vertically-moving supports,and mechanism arranged to automatically lift the supports during the sidewise movement of the machine; substantially as described.

3. Aeharging-machine mounted upon suitable trucks,vertically-movable supports upon the machine arranged to receive the pile of plates, and cam mechanism arranged to automatically raise and lower the supports during the movement of the machine; substantially as described.

l. A laterally-movable charging-machine CAMILLE MERCADER.
