SAN D-BOX FoR CARS.

SPECIFICATION forming part of Letters Patent No. 512,480, dated January 9, 1894.

Application filed March 27,1893- Serial No. 467.774. (No model.)

To all whom it may concern:

Be it known that I, HENRY MOPHERSON, of the city of Troy, county of Rensselaer, and State of New York, have invented a new and useful Improvement in Sand-Boxes for Cars, of which the following is a specification.

My invention relates to improvements upon that class of apparatus which is used upon street cars operated to run upon rail tracks; the purpose and use of which apparatus are to distributev sand upon the tracks when greasy or 1cy, so that the wheels will turn upon the ralls instead of sliding thereon. As heretofore made devices of this kind have been constructed with a hopper having a sand delivery chute connected with the bottom of the hopper, and the interior of the latter provided with an agitator designed to stir up the sand, and facilitate its descent into the chute from whence it passes to the rails. The chutes of these older devices connected directly with the hopper bottom, and as thus placed when the cars were in motion, would suck up moisture that would cause the sand to pack in summer, and to freeze in winter, so that they were difficult to operate and uncertain in their action; To avoid these contingencies, and'to obtain better results, from anapparatus designed for these uses, is the ob ect of my invention. This better adaptation of the purposes designed I accomplish by means of a cylindrical-form sand receptacle, which at its sides is hung in trunnion ournals; is made with a delivery spout-form mouth that is tangent to its outer cylindrical-form face, with this receptacle operated to in partrotate on its bearings so as to bring its delivery mouth down over a chute leading to the track for the delivery of sand thereto, and which receptacle when the power applied to thus tilt it on its bearings is released, will automatically by the action of gravity return to a position with its delivery mouth uppermost, all of which will be more fully set forth hereinafter and detailed in the claims.

Accompanying this specification to form a part of it there are two plates or drawings containing six figures illustrating my invention, with the same designation of parts by letter reference used in all of them.

Of these illustrations Figure l is a perspective of my improved sand box; showing alsoa part of the car floor on which the former rests; a part of one of the car truck cross beams, with a part of the shaft, its drum pulleys and draw-belts, by which it receives motion and operates the sand box. Fig. 2 is a top view of the sand box showing part.0f the platform beam, part of the car-truck end beam, also part of one of the car truck side beams and car floor. This view shows also in a dotted line the shaft operating the sand box, and the draw-belt and drum pulley on the shaft, by which the latter is operated. Fig. 3 is a central vertical section of the sand box taken on the line 0c, 00, of Fig. 2. Fig. 4 is a section taken centrally through the sand box, the sand chutes, the car platform and floor, and the shaft hanger; with the vertical shaftand operating crank, its drum pulley and drawbelt shown in side elevation, and with the sand box illustrated as in a position to deliver sand to the track. Fig. 5 shows the same parts that are illustrated at Fig. 4, but with the sand box turned so that its delivery spout is uppermost, and in a position to not deliver sand, and with the supplemental chute shown as raised. Fig. 6 shows a modified form of sand box.

The several parts of the apparatus thus illustrated are designated by letter reference and the function of the parts is described as follows:

they are each made with a journal box J, for

one of the trunnion-form journals T.

The letter M designates a mouth or spout for the discharge of sand from the box when the latter is turned half a revolution, so as to bring the mouth or spout projecting downward. This month or spout is tangentially projected from the concave perimeter of the sand box.

The letter W designates a weight or counterpoise preferably made in a segment form and arranged on that half of one of the sides of the sand box which is diametrically opposite to that whereat the spout or mouth is located, and the function of this weight or counterpoise is to automatically cause the sand box to rotate part of a turn so as to bring the spout or mouth uppermost after having been operated to turn down to deliver sand.

The letter D designates a drum pulley arranged on, so as to turn with the trunnion journal T, on which it is attached, and the letter S a shaft having its journals in hangers H, downwardly projected from the under side of the car truck. The letter D designates another drum pulley arranged on, to turn with said shaft S, said pulley D having tangentially connected thereto a draw-belt (Z which at its other end connects tangentially with the drum pulley D, on the trunnion journal J; and the letter D designates another drum pulley arranged on, so as to turn with the said shaft S; and the letter (Z designates another draw-belt that tangentially connects with the drum pulley D at one of its ends, and at the other end, tangentially connects with the drum pulley D, on the lower end of the vertically placed operating shaft S which at its upper end is constructed with a crank K. As thus made and arranged when the operating crank K is moved to cause the shaft S to make half a turn, it operates the drum pulley D thereon, and this actuates its connected drawbelt 61 to operate the shaft S to make half a turn, and this causes the pulley D", by means of the draw-belt (1 to operate the drum pulley D to move the sand box so as to have it partly revolve on its journals, and to turn down until the mouth or spout M, is in a position to discharge sand therefrom, and when the tension upon the crank K is released, the counterpoise weight XV causes the parts to make half a turn with reverse motion so as to bring the mouth or spoutnppermost.

The letter I designates a stop made on the side of the sand box, which as the latter turns downwardlyto discharge sand,when itreaches the desired limit, this stop I engages with the side edge of the adjacent standard A, to prevent its further descent. The letter I designates another stop made on the side of the sand box, and this stop in like manner engages with the side edge of the adjacent standard A, to prevent its momentum,as acted upon by the counterpoise, from carrying it too far in return movement. iVhile these stops perform the function of limiting the progressive and reverse rotation of the sand box they perform another useful and quite as important function, which is accomplished by jarring or shaking up the sand when the box is suddenlybrought up against the stops; thus freeing it from any packing tendency that might occur from the settling consequent upon the jarring of the cars while moving.

The letter C designates a chute located in the car bottom, said chute having an upper expanded and flaring top, and a contracted lower end e The letter O designates a supplemental chute that is made to be operated telescopically within the other chute, so as to rise and fall through aoonnection made with the sand box. This connection consists of a link L, which at its upper end Z is pivoted to the side of the spout M, and at its lower end Z is pivoted to the top of the supplemental chute 0 at its side. box makes a half revolution, it carries down the supplemental chute within the chute Q, until the discharge end 6', of the former 1s close to the track, and when the sand box makes a half revolution in reverse movement the supplemental chute is drawn upwardly within the chute C, where it is out of the way.

In the modification shown at Fig. 6, the sand box has its trunnion-form journals eccentricaliy placed so that afterbeing moved half a revolution to bring the mouth or spout down to where it will discharge sand, instead of being operated by the attached counterpoise W, the eccentric position of the journals relatively to the box, when acted upon by gravity, causes it to automatically make a reverse motion of a half turn.

The generic feature of my invention being to have the sand box operated so that after having made a half revolution under tension, and caused to come into a position where it will discharge sand, and to automatically make a half turn with reverse motion when the tension is released, I do not limit my 1nvention to the precise means which I illustrate, as so employed to operate the sand box, but I do limit my invention to the use of a means that will operate it in substantially the same manner.

I am aware that it is not new to arrange a sand-box beneath the car bottom, said sandbox being provided with trunnions on which to turn and be operated by a bell-crank lever and a tripping pin, and having a spout of sufiieient length to deliver sand and water directly to the track. When thus arranged the sand-box is in a position to be injured by collisions and articles upon the track, with its contents exposed to the direct action of frost and cold and at times when the sand is most needed upon icy tracks.

By locating my sand-box within the car heneath the car seats, and combining with the sand-box so located a passage-way through the car bottom the sand is kept dry and free from the effect of cold, and the contingencies attending upon its being located beneath the car.

iVhile I have shown two chutes, one work- As thus made, when the sand ing within the other, yet either may be used independently of the other in combination with my improved sand box.

As thus made and arranged to be operated, a sand box is produced in which no packing of the sand can occur, and which when not delivering sand has its mouth or discharge chute within the car, which as thus arranged prevents the dampening and packing of the sand in warm Weather and its freezing in winter.

Having thus described myinvention, what I claim, and desire to secure by Letters Patcut, is
