'CHARGING GAs-REToRTs. y

The Schedule referredto these Letters Patentend making part of theusame. I

To all whom 'it may concern:

Beit known that I, N. O. J. TrsDALE, of the city of New Orleans, State of Louisiana,'haveinvented a certain new and useful and improved Machine for Putting into Gas-Retorts the 1li-oper Charge of lCoal-to be Carbonized; and I do hereby declare the following to be a full, clear, and exact description of the same,L reference being had to the annexed drawing, making a part of this specification, on Whichl Figure l is a perspective, and

Figure 2, a sectional view of said machine. l

My invention is a mechanical organism,- through the agency of which gas-retorts can be more expeditiously and properly charged with coal, and with less labor and cost than by any method hitherto known or practised. 1 Y

This organism consists of anelongated shallow open box, in which is adjusted .arruovable and reversible web orlink-bo'tton'cr apron, and'properfmea'ns for operating 'the saine, that is sustained in a guide-way or' sheath, in such manner as to have a reciprocating endwise motion, corresponding in its extent with the length of the retort, the said guide-way beingl supported on a proper frame or carriage on wheels, resting on a railway, so as to be movable, and vtherefore readily susceptible of being taken "from one bench of retorts tu another', and into the coal-store.

In other words, my invention isa machine which charges gas-retoits without further hand-labor than is requisite to place the coal in it, and then to cause the same to be discharged in the retort, the operation being effected with great economy of time and labor, as compared with any other mode that has hitherto But my invention will be more quickly understood, both in respect of its mechanical construction and its mode of operation, by referring to the drawing, on which the same letters denote like parts at both the gunes.

In the drawingl A represents an ordinary-gas-retort, as constructed in this country, in a detached state, the object of its delineation being to illustrate the manner in which my machine enters thc saine when loaded; and

B, what I denominate'a guide-way, whose function it is to sustain the elongated shallow open box O, which, for purposes of distinction, I calla charger, e and also suitable mechanical appliances or means for operating the said charger and its reversible bottom D, which consists of a series of narrow strips, as shown, that are hinged together, lin any usual manner and by any proper means, so as that the said bottom maybe readilyilcxiblc--a necessary condition, as will hcrcaitcr be shown, to the successful working of r'nyinvention.

`very near tlrelower edges of Y The guide -iway B is 'fixed on a-railway-carriage, moving through the retort-house upon a railway laid along the front of the fire-,stack in'which the retorts areV set, in such manner as to bring the proximate extremity of the same very n ca-rly inv contact-withy thefront of the mouth-piece of the retort.

On the carriage may be placed one or any number' of my machines, 'accordingly as the number of -rctor-ts in a benchmay vary, which. are to be adjusted on the same at such heights and. in such positions that. each charger, resting in its rguidc\vay,.will have its bottom just suiliciently above the l'evel -of thebottonr ofthe retort which is to be charged by it to enter said retort whenever' the carriage is placed in position before the bench to charge the'retorts therein. So worked in setsof three orrive machines on one carriage, they can all be driven into `'the retorts, rand withdrawn therefrom, by a single motionf and at a single operation, ysimultaneously delivering their'seVCra-lcharges,-LA

smootlrly. and accurately, and at any desired rateot' speed. Y

As I donot claim the carriage, nor, in this application, anyv particular means for operating a number of my machines, I have not considered it necessary to show said` carriage, nor any such means, ou the drawrng.

The guide-way B consists of two vertical sides b b', that are held together, and at a proper distance apart, according to the width of thc retorts, by transverse screw-bolts c, that all occupy the same horizontal line, the sides b b', as shown on the drawing.

J .ust above the line of the bolts c, a ratchet, or toothed bar, d, is secured upon. the interior surfaces of each ofthe sides b b', as shown; and just above this bara projecting slide or rail, e, to subserve a pur-` pose hereafter to be indicated.

The ratchet-bar d, and the rail c above it, are parallel to each other, and both occupy horizontal planes or lines.

On top of each ofthe sides b b is another' rail, g y,

Nor do the rails q y extend the whole length of the guide-way B. They terminate near the inner' ends of the guideway, by which I mean the ends next the retort, so as to provide `an opening, i, upon each side ot said guide-way, for a purpose to be indicated when I come to describe the operationof the machine.

by means of the cog-wheels Z, and winds up the chain o. This draws the bottom D over the pulley at 4, and thus reverses the same, and deposits the coal in the rctorts, in even and regular measure, as fast as the charger moves out of them.

Inl the reversal of the bottom D, as above described, it is drawn between the bar e and the projecting flanchcs at the bottom edges of. the sides.2 of the.

charger, which latter lsupport it ou its 'longitudinal edges, and thus prevent it from sagging or falling down below the bottom of the charger.

The length of the ratchet-bar l is calculated with reference to the extent to which the bottom is to be reversed, so that the pulley F passes beyond these bars at the instant the charge is delivered.

Po-prevent the bottom D passing entirely ofi its upper plane, the catches 5 are so placed as to take. against the bracket k the moment the charge has been delivered and the ends of the ratchet-bars have been passed by the pulley F. Arriving at the inclined bars h, the pulley F ascends the same, the light-traps g g interposing no appreciable resistance until the rollers p once more rest upon the rails g, the traps falling back into their places as Vsoon as the said rollers advance sufficiently beyond the openings to allow them to doso.

The pawls on are now disengaged from their racks,

F, and then the bottom D is pulled by hand, by means ofthe bracket k, back to itsA original position, and the machine is ready for another operation, and so on indefinitely.. Y

Having thus described my invention,

Vhat I claim, and desire to secure by Letters Patent, is-

1. The guide-wayB, when constructed substantially as herein described, for the purpose set forth.v

2. The charger G, when provided with the reversible bottom or apron 1)and constructed and operating substantially as and for thegpurpose set forth.

3. The combination of the guide-way B and thel charger C, when these parts are constructed, arranged, and conjointly operate substantially as described, for the purpose set forth.
