SAN D-BOX FOR RAI LWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 408,178, dated July 30, 1889.

Application led June l2, 1886. Renewed November 28, 1888. Serial No. 292,131. (No model.)

l T0 all whom t may concern.-

a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, and LOUIS JORDAN, a citizen of the vUnited States, residing at New York, in the county of New York and State of New York, have invented new and useful Im provements in Sand-Boxes for Railway Oars, of which the following' is a speciiication.

The invention herein shown and described relates to improvements in sand-boxes for railway-cars, various features of which form the subject-inatter of an application tiled by us on October 2S, 1886, Serial No. 217,473.

Our invention. in this case consists, essentially, in the combination, with a sand-reservoir and its discharge-tube, of a valve propguided in a chest, a stirrer projecting upwardly from the valve and into the discharge-tube, and mechanism for operating said valve so as to control the discharge of sand from the reservoir, an iniiexible discharge-tube provided with a non-conducting covering, and which may be used both as a discharge-tube and an obstacle-remover, and also of a device for retaining' the valve in its closed position, all of which is more fully pointed out in the following' specification and illustrated in the accompanying drawings, in which- Figure l is a side elevation of a street-car with a portion broken away to. more plainly show our improved sand-box and valve-locking device. Fig. 2 is a vertical central section of the lower part of the sand-box on a larger scale than the preceding figure, sl1owing the tubular opening or upper dischargetube and the position of the stir-rer in the same when the valve is closed. Fig. 3 is a horizontal transverse section on the plane oo, Fig. 4. Fig. 4 is a vertical section in the line y y, Fig. 2. Fig. 5 is a vertical section of the iniiexible discharge-tube and obstacle-re-V mover. Figs. (l and 7 -Figu 7 being a vertical section taken on the line e' e, Fig. G-illustrate the device for holding the valve in a locked position.

Similar letters refer to similar parts throughout the several figures.

In the drawings, A designates the sandreservoir. The bottom a of this reservoir is inciined, so as to make the sand-receptacle itself virtually a hopper. 'The unoccupied space of the reservoir lying beneath this, aided by the perforated portions of its sides which admits of a current of air, forms the 6o means whereby` the sand is kept in a dry condition. This is amatter of great importance, for if the sand or other material should become muddy or thickened up by confinement it would not iiow. This reservoir A is provided with a discharge-tube constructed in two parts B and B', which lead down and u nder the wheel O of the car.

In our application, Serial No. 217,473, we have shown and described a rubber discharge- 7o tube, and have stated therein that we prefer to use it instead of an iron discharge-tube;` but the form shown in Fig. 5 herein may be used both for the purpose of a dischargetube and an obstacle -remover. It can be united to the shank D2, Fig. 5, by an ordinaryT couplingL. When this construction is used, we cover the tube and connections with a rubber or other non-conducting jacket N In order that the upper discharge-tube B So may be properly protected from the action of the elements, we either tightly cover the tube and connections with rubber or other nonconductor,l as shown at b, Fig. 2, or by constructing an air-case around it, as shown and S5 described in our application, Serial No. 217, 473.

A casing D, having a suitable cover D', is located in the discharge-tubeB, and both casing and cover are provided with tubular threaded shanks D2 D3, whereby they are 9o coupled to the discharge-tube. In this casin g is situated a valve E, Figs. 2, 3, and 4, which is provided with a suitable port or opening e, that opens the discharge of sand through the tube B when in line therewith. A. seat is provided for this valve in the cover of the casing D, against which the valve is constantly pressed by means of springs G G, which are interposed between the back of the valve and the bottom of the casing. A rod f, Fig. 2, roo which extends from one end of the valve beby a spiral.

yond the casing D, is encircled spring F, that is conned between the casing and lugs or projections on the post, so that the tendency of the spring is to return the valve to its closed position and retain it in such position. To move the valve in the proper direction, bring the port or opening in line with the receiving end of the casing, so as to permit the discharge of sand from the reservoir. Any well-known mechanism may be employed-such, for instance, as shown in the drawings. The valve is connected by a link; H, Fig. l, to one arm of a bell-crank lever I, the other arm of which is connected with a push-rod t', which projects through the platform in a convenient position to be operated by the attendant. The spring F returns the valve to its closed position when the bell-crank lever is released.

WVe illustrate in Figs. G and 7 the means we intend to use to hold the valve E in a locked position. t' is the upright push-rod attached to one end of the bell-crank lever I, which push-rod, as before mentioned, extends upwardly through a hole in the platform j of the car and terminates in the enlarged head 7c, upon which the operator presses his foot when he desires to apply the sand. lis a hookshaped block or detent centered on the bolt m, which is pressed by the operator-s foot under the enlarged head 7c of the push-rod t' when it is desired to lock the valve. When it is desired to work the valve, the block Z is thrown out of engagement with the push-rod i and into the position shown in dotted lines in Fig. G.

It is desirable that the valve should rem ain in a locked position when not in use.

In order to break up lumps of sand that may form in the reservoir, and also to secure a steady flow of sand through the dischargetube when the valve is in its open position, a stirrer J is attached to the valve, which stirrer extends into the tubular shank of the castube above the Valve, and may have any convenient shape; but we prefer a yoke or staple shaped stirrer. This stirrer is situated directly in advance of the port oropening e of the port or opening e therein, the yoke or staple shaped stirrer J, carried by the valve, and mechanism, as described, for operating the valve, substantially as set forth.

2. The combination, with the platform j,

.push-rod t', bell-crank lever I, link H, valve E,

and spring F, of a locking device consisting of the hook-shaped block Z, centered on the bolt m, substantially as and for the purpose hereinbefore shown and described.

3. The combination of a sand-hopper having a tubular opening in its bottom leading down to a valve, and a slide-valve provided with a rod or stirrer which extends upward in said tubular opening, substantially as described.

4. In a sanding apparatus for street-cars, the combination, with a headed push-pin for operating the valve, of a detent pivoted to the platform of the car and adapted to be moved under the head of the pin to prevent its operation, substantially as described.
