CINDER-CAR.-

SPECIFICATION forming part of Letters Patent No. 274,786, dated March 27, 1883. Application filed December 19,1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM KELLY, a citizen of the United States, residing at Scottdale, county of Westmoreland, State of Pennsylvania, have invented or discovered a new and useful Improvement in Apparatus for Removing Furnace0inder; and I do hereby declare the following to be a full, clear, concise, and exact description thereof', reference being had to the accompanying drawings, making a part of this specification, in whichlike letters indicatin g like parts- Figure l shows a side elevation of' my improved apparatus. Fig.`2 shows an end elevation of the receiving and dumping car, and Fig. 3 is a perspective view of the cinder-box of the car.

My invention relates to certain improvements in apparatus for receiving slag, cinder, Src., from furnaces, and removing and dumping or emptying the same.

`In general terms my invention consists in a new and improved cinderfcar having a later- .ally-dumping box with a removable side, in

vcombinationwith a lifting and rotary crane mounted on a truck and movable with the cinder-car, such crane being adapted by its construction for removing and replacing the removable side of the box, as hereinafter more fully described and claimed.

In the drawings, A represents a car box or body formed by preference ot cast-iron, with bed a, sides c a2, and ends a3 a4. The side c2 and ends a3 a4 are secured together rigidly by riveting, as at a5, or in other convenient way; and they are also secured by tenons and mortises as, or in other suitable manner, tothe bed a. In order to prevent warping, the bed a a is formed of three pieces, as illustrated in Figs. l and 3, with ribs b cast ou their under faces, and they are bound together by two or more bolts,- b, passed through the ribs. The side c ot' the box is removably secured to the ends c3 u* by tongues or tenons c ou the latter, which enter mortises c in side a', and

by removable pins c2, which are passed through the tenons outside of the plate, or side a when the latter is in place. In order to prevent loss of these pins, they ma-y be secured to some part of thebox-for example, to the ends c3 c4- v by short chains c3. In dumping or emptying the box A this side c is removed, :as presently described, and in order to facilitate the lateral discharge of the contents the box `is made ot' trapezoidal form,the side a? being shorter than a and thel ends a3 a4 diverging toward the side a. With this formvof box, on removing `the side a" and tipping the bed a, so as to depress lthe open side, the contents, which may be wholly or partially iluid,semisclid or solid, or in partin all stages from fluid to solid, will How or slip freely oft' the bed andl empty the box without binding on or being retarded by the stationary or xed sides. It', however, from roughness on the bed or for other cause the contents should stick in the box, it may beV started by means of suitable pikes or bars inserted for prying through holes a7, made in the lower edges of the sides; or, in case the contents is still fluid, one or more of these holes maybe opened and the'uid contents allowed -to run out; and iu order to prevent such running out prematurely, the holes are stopped or tamped with clay `or other suitable material preparatory to filling the box at the furnace. In order to dump or tipthe box, as described, it is mounted by axis-rod b, or by equivalent trunnions, secured by cross-beams b', or in other convenient way, to the bed a upon bearing blocks or holsters B, which latter are se cured in any convenient way to the front and rear ends ot' a cantruck, D, which may be of any suitable construction, adapted to run upon a railway-track, E, laid fromthelfurnace to the desired place of dumping the cinder.

l In order to sustain the carbox A in horizontal position, with provisionfor tipping or dumping when desired, I make use ot standards c, which are secured to and extend from the truck-frame upward a proper distance to aft'ord a support for the box under itsl short or closed side and swinging bars e', which are pivoted to the bed-beams b on the opposite or long side, a', of the box. Shoulders c2 are formed on the lowerend ot' these swinging bars, adapted to rest on the truck-frame and supportthat side of the box in the desired position. By pulling these rods off their shoulder-rests ou the truck-frame, by means of cross-rods e4, the box A may turn on its pivot. Owing to the ICO both trouble and increased expense.

increased length of the side a, and the corresponding increase in the capacity of the box on that side, there will be a preponderance of weight when the car is loaded on the side toward which it tips, sufficient to cause the desired tipping when the supports c' are removed. This feature of advantage may be secured, however, by making the pivots b out of the central line toward the closed side of the box; but I prefer to employ the trapezoidal form of box for securing such preponderance of weight, on account of the additional advantage secured in clearing the box of its contents, as before described; also, when the contents are dumped, the side a being removed, there will be a preponderance of weight on the closed or elevated sideof the box, causing it to right or to assume its horizontal position. This automatic action of self-dumping when loaded and self-rightingwhen emptied relieves the workmen from both duty and danger.

In operation the molten cinder, slag, dto., is run from the cinder notch of the furnace, through a suitable trough or spout, into the car box A, which is run alongside on lthe track E, of lower level. By employing a sufficient number of such cars, each may be allowed to stand after filling until the contents have become solid, or a crust formed of considerable thickness; but such waitinginvolves l prefer therefore to provide for dumping the cars without waiting for the contents to cool; and for this purpose, and also to provide for removing and replacing the side a at the place of dumping,I make use of a crane device mounted 'upon a car-truck and movable with the cindercar, which is constructed as follows:

Upon a truck, H, and body H', of any suitable form and construction, is mounted a rotary mast or a crane-post, I, by step-bearing t' at its foot, and cap or box f5 at its top, from which brace-rods 2 pass to different points ot' the car-body, and thereby rigidly support the bearing i', and through it the top of the post, with freedom, however, of rotary motion of the post in its bearings. 0n the upper end of the post or mast is secured the jib I', stiftened by brace I2. This jib is of sucient length to reach forward nearly to the center of the cinder-car when the cinder-car and crane-car are coupled for moving, as illustrated in Fig. l. Upon the outer end of the jib is mounted a lifting-lever, N, by pivot-fulcrum n and surrounding strap n', notches u? being provided on the under side of the lever, adapted to bear upon the pivot-pin and prevent endwise movement of the lever. Provision is thus made,

also, forchanging the distance between the end of the lever and its fulcrum, as may be desired. Upon the outer end of the lever is formed a hook, r, adapted to engage a bail, r', the ends of which are secured to lugs r2 ou the edge of removable side a. In order to remove this side, the lever-hook r is passed under the bail, as shown, Fig. 1, and the opposite or long end is pressed downward by a workman sufcientlyto raise or bear the weig ht of side a; and to this end the mortises c are made to exceed the tenons csomewhatin width, so the side a may rest upon the bed a when not suspended by the lever, and may be'raised to clear the bed without binding upon the tenons; or, if desired, the side c may be raised by the lever sufciently to bear upon the under side of the tenons, and thusease the weight on the swinging bars e', so that they may be easily set to catch on their rests but little as a preparatory step to pulling or knocking them off entirely when ready for dumping. The side may be secured in the desired suspended position by a chain, s, which may be fastened to post I, as ats', and hooked to the end ot' the lever, as at s2. When thus suspended the crane is turned on its post I, carrying the side a laterally out of the way, when the car may be dumped, as before described. When the carbox is righted the crane is swung back, carrying the side a into position upon the tenons c, where it is secured by the pins c2.

Various modifications may be introduced in l the details of construction of my improved apparatus without departing from myinvention, though I prefer the construction shown and described. For example, one ot' the ends a3 or a4 may be at right angles to the sides a a2; or staple and hook or other suitable connection may be made between the ends a3 a4 and the removable side a; also, other equivalent devicesmay be substituted for the bail r and fastening-chain s.

With myimproved apparatus the cinder may be run directly to the place of dumping, and whether the contents be fluid or solid, the side a' may be removed and the contents be discharged quickly and with little manual labor.

The apparatus is simple and cheap. in construction, is easily operated, and provides for much more convenient and expeditious removal of the cinder, slag, &c., than means heretofore in use. If but one cinder-.car be used, the two trucks D and H may be permanently secured together and form practically one car but ordinarily it will be more convenient to use two or more cinder-cars, and in such case I prefer to employ the usual or any convenient form of detachable coupling, as at S, for connecting the two trucks so as to move together on the track and to hold them in proper relationship forremoving and replacing the side a.

The adaptation and eo-operation of parts effected as above described insure convenient and easy manipulation without exposing the workmen to danger, lor the track to injury by burning, as heretofore.

I claim herein as my inventionl. In a dumping cinder-car, a box, A, of trape'zoidal form, having in combination three fixed sides, a2 a3 a4, and one removable side, a', the latter being the longer one of its two parallel sides, substantially as set forth.

2. In a cinder-car, the combination of traperco IIO

amuse l s zoidal box A,-having removable side af, truck D, and `pivot-bearings between the box and truck in the longitudinal central line of the` car, substantially as and for the purposes set forth.

3. In a dumping cinder-car, a trapezoidal box, A,havin,9,` a removable side, a', and Xed sides a2 a3 a4, with pry-holes al, made in some or all such sides, substantially as set forth.

4. The combination of three-part` cast-iron bed a, with ribs b', cast on theunder faces of such parts, binding-bolts b3, and sides a a2 a3 a, substantially as set forth.

5. In a laterally-dumping cinderLcar, a box,

A, having in combination a bed, a., two inclined I5 ends, a3 a4, fixed to the bed, with tenons c on the indivergent ends, removable side a', having mortises c therein, and pins o, substantially as set forth.

6. The combination of truck H, crane-post zo I, jib I', lever N, and chain s, substantially as set forth. t

In testimony whereof I have hereunto set my hand.
