COAL RECEPTACLE AND ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 549,090, dated October 29, 1895.

Application filed September 25, 1894. Serial No. 524,097. (No model.)

To all whom it may concern.-

Be it known that I, CHAUNOEY L. CHAP- MAN, of Dunlap, in the county of Harrison and State of lowa,have invented certain new and useful Improvements in Coal Receptacles and Elevators; and I do hereby declare the following to be a full, clear, and exact descrip-E tion 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 coal receptacles and elevators, and is especially designed for use in connection with steam-railroads.

It has for its objects, first, to provide efficient subterranean storage-bins beneath the main tracks of a railroad, whereby coal can be dumped thereinto from dump-cars on said track; second, to provide simple and highlyefficient means for withdrawing from said bins any desired amount of coal, the same falling into suitable transfer-cars, and, third, to provide a new and improved form of elevator for rapidly raising said transfer-cars to a point above a car or tender on the main track and dumping the contents'of said transfer-car into said car or tender, then quickly lowering said transfer-car, the parts of said elevator not projecting in any way to form ob struction to the main track when the elevator is not in use.

To these ends the invention comprises the novel features of construction and the combination and arrangement of parts substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective, with parts broken away,

showing the elevator in its lowermost position. Fig. 2 is a similar view looking at the opposite side to that on which Fig. 1 is taken,

the elevator being shown at the upper limit of its movement. Fig. 3 is an end view, enlarged, 0f the elevator-frame and operating mechanism therefor, parts being broken away. Fig. 4 is a plan of Fig. 3. Fig. 5 is a detail of the brake. Figs. 6, 7, and 8 are details. Fig. 9 is a view of the air or steam inlet-valve with parts broken away.

Referring to the drawings, A designates the stationary frame, having four posts or uprights a, supporting at their upper end a gable roof or covering a. Upon the inner opposed faces of each two of the posts or uprights a are secured rack-bars o which extend from about the center of said posts to near the top thereof. A cross bar or rod 0, is connected to two of the posts or uprights a at a point above the upper ends of the rack-bars a and a notch 0. is formed in the under side of said cross bar or rod.

B designates the movable frame of the elevator, the same comprising four corner posts or uprights b, which are designed to fit and move within the space formed by the bars or uprights a of frame A. These posts or uprights b have on their outer faces rack-bars b, corresponding to and located opposite the rack-bars a of posts a, a space being left between said rack-bars, as shown in Fig. 3.

C is a horizontally-disposed platform secured to the lower ends of posts or uprights b, and upon it are two rails b having bent or upwardly-curved ends b.

D is a movable frame or carriage composed of outer end bars 01 d and four inner short bars d in which and in said outer bars at d are journaled the ends of rollers 01 thus providing four pairs of rollers, one pair at each corner. The rollers of each pair are designed to bear, respectively, against the outer and innor longitudinal edges of the posts or uprights a I), thus preventing any spreading of the latter and providing for easy movement of the frame D. Extending longitudinally through this frame D are two shafts E, upon each of whichv are rigidly secured pinions e, which are located between and inter-mesh with the rack-bars a and b of the posts or uprights a b. Upon the projecting ends of these shaftsE E are mounted two large gearwheels 6, which are designed to intermesh with each other. The gear-wheels 6' receive their motion from a pinion 6 mounted on a shaft 0 journaled at its inner end in crossbar d of frame D and at its outer end in a cross-bar 6 supported by shafts E, said pinion 6 meshing with one of the gear-wheels c. This pinion is loose on its shaft and is caused to revolve with the latter byatwo-part clutch e", which is normally held closed or locked by a spring 6". One part of this clutch is secured to or formed with the pinion '6', while the other part is attached to a brake-drum E, both of which are held by a spline on shaft a so as to revolve therewith and be capable of being moved longitudinally thereon. The spring e normally holds the two parts of the clutch united. Motion is imparted to this shaft e either by a crank e or two engines F, havingpitmenf, connected toaorankarm f at one end of said shaft. These engines are supported by the frame D, andinto. the steam-chestf thereof opens a pipe f (see Figs. 3 and 4,) to which is connected a tube f leading from a compressed-air reservoiror boiler of alocomotive rother source of pressure. The valve-rods w are indicated in Figs. 3 and 4, and at their outer ends they on gage an eccentric tu'on shaft 9 (See Fig.4.) From this pipe f projects a perpendicular springpressed valve-rod f (see Figs. 3 and 4,) which, when raised in the valve-easing f unseats its valve 10 and. allows the air or steam to pass to the chests of the engines F and thereby set said engines in motion, causing the turning of the shaft e and the revolution of gear-wheels e, which, through the agency of the pinions e, engaging rack-bars a b, will effect the rapid elevation of the frame B. The elevator frame ascends "at double the rate of the movable frame D and the propelling or operating mechanism carried thereby. The ascent of the elevator-frame is automatically stopped by the lowering of valve-rod f which causes the valve to be reseated when the upper end of said valve-rod strikes against cross-bar a ,'entering the notch thereof, after which the supply of air or steam is cut off by any suitable valve (not shown) at or near the reservoir or boiler, and is not again admitted to the pipe until after the elevator-framehas been lowered and is to be again raised. The descentof the elevatorframe is effected by the disengagement of the outer part of clutch e from the part 'attached to pinion e thereby permitting said pinion to revolve freely on its shafts. A suitable brake, as indicated at F, may be used to control the descent 'of the elevator, the same encircling and engaging the brakedrum E. By applying the brake and moving the same laterally the drum E will be moved on shaft e thus disengaging the parts of the clutch. As the elevator-frame B reaches the upper limit of its movement, the pinions e are in engagementwith the lower ends of the rack-bars b and the upper ends of rack-bars a while, when said elevator-frame is lowered, said pinio'ns are at the lower ends of rack bars a and the upper ends of rack-bars b.

When the elevator-frame is at the upper limit of its movement-,the platform 0 thereof is about on a line with the movable frame D, the tracks or rails b thereof projecting above the end cross-bar d. To one end of this frame D is connected a board G, which servesv as a platform on which one of the operators stands.

A platform g, consisting of a single board, is supported by hangers or loops 9, depending from the projecting ends of shafts E. Upon this platform an operator can stand for turning the shaft 6 by crank-handle e and also for controlling the position of the clutch.

His a swinging frame of approximately triangular form, the lower convergent ends of its sides being provided with shoes it, having rounded or ball-like ends h, fitting in-socketplates 71, rigidly secured to the stationary horizontal base 72. surrounding the stationary frame A. These socket-plates k have stops or shoulders h, which serve to limit the outward movement of the frame. Both the inward and outward movements of this frame are further controlled by chains 72 secured thereto and also to two of the posts a. Upon this swinging frame H is a track-frame I, which is hinged or pivotally mounted at its center, as at i, to the outer upper end of frame H, so that said track-frame is free to move to occupy an inclined position, as shown in Fig. 2, its movement, however, beinglimited by a strap 2'', secured atits ends to said track-frame and passing beneath the upper portion of frame H. The outer enact the rails z' 'on this track-frame are bent or curved upwardly, as shown at i and form stops for the transfercar J. The swinging door j of this car has a cross-barj, the projecting ends of which are designed to be engaged by pivoted hooks 3' on the sides of said car. When the trackframe is tilted,as shown in Fig. 2, each hook 7' is disengaged from bar j by an arm f, which is pivoted at itsouter end to the trackframe I and at its other end to the free end of said hook, and is connected by'a link or bar 7' to the frame H, said link serving to move said arm when thetrack-frame is tilted. Th us the contents of the transfer-car are allowed to (lump into a car or tender W, located on the main track K.

I will now proceed tod'escribe the means employed for storing the coal deposited adja cent to'the elevator by dumping-cars, and ready to be conveyed to said elevator so as to be transferred to a car or tender on the main track.

L L designate hopper-like bins located beneath the main track K, any number of which bins may be employed. Over these bins are trap-doors Z, through which coal deposited by suitable du mping-cars (not shown) passes into the bins, The bottoms of the latter are provided with "openings which are normally closed by sliding doors Z, having rack-bars Z with which engage pinions l on a crank-shaft Z be moved beneath the hoppers or bins to allow the coal to pass there from into transfercar J. Immediately above each of these openings in the bins is an agitator M, which consists 'of a cranked or bent shaft extending transversely across'the bottom of the bins and journaled in the side of the latter. \Vhen the doors of the bins are moved from beneath the openings, the agitators are designed to be operated to effect the loosening and lowering of IIO By turning this crankshaft the doors can the coal. Beneath the bins and parallel with the main track K is a track-N, on which the transfer-car J is designed to be located when receiving the coal from the bins, and at right angles to this track is a transfer-track n, a turn-table n being located at the point of conjunction of these two tracks. The rails of the track N align with the rails 17 of platform 0 of the elevator when the latter is lowered.

From what has been said it will be seen that upon the transfer-car J being supplied with coal from the bins beneath the main track the same is transferred by the turn-table to track n and then run onto the platform 0 of the elevator. The operator on platform G then raises the valved rod f permitting the engines F to operate, (or if the latter are not in use the operator on platform g turns the crank-handle 6 efiecting the revolution of pinion 6 which travels with its shaft e by reason of the clutch connection, and the large gear-wheels e being thus revolved the pinions e intermesh with the rack-bars of the stationary and movable frames, causing the rapid elevation of the latter until the car-carrying platform 0 is brought on a line with the top of the swingingframe H, when further movement of the elevator is automatically stopped by contact of the valve-rodf with cross-bar a The rails 11 of platform 0 being then in alignment with the tracks 1', the transfer-car is pushed forward on the latter, and its weight overcoming the center of gravity of trackframe I the latter is caused to tilt, and the door of said car being opened in the manner hereinbefore stated the coal is readily dumped into the tender located on the main track. After this is accomplished the track-frameis caused to assume its normal position by the operator on platform G bearing downwardly on the inner end of said track-frame, and the car is then again moved onto the platform 0, and the operator on platform g, by disengaging the clutch e from pinion e allows the elevator-frame to automatically lower. When the platform 0 reaches the lower. limit of its movement, the transfer-car is removed therefrom onto the track Nand then pushed into position for further use.

It will be observed that when the elevator is not in use the swinging frame H is swung inwardly between two of the posts or uprights of the stationary frame A, as shown in Fig. 1, so as not to be in the way of or form any obstruction to the passage of cars over the main track K.

The advantages of my invention are apparent to those skilled in the art, and it will be observed that I have provided simple, convenient, and inexpensive means whereby coal may be conveniently stored and can be quickly transferred to an elevated point and dumped into a car or tender.

It will be noticed that the elevator mechanism employed by me is strong and durable and highly efficient and rapid in operation.
