Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed April 20, 1906. Serial No. 312.932.

T0 all whom it 17a/ay concern:

Be it known that I, JACOB ROEDIGER, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Sand-Delivery Boxes for Railway-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates toV a box for delivering sand from a suitable receptacle to the rails of railway-tracks, the box being constructed to provide for the reception of the sand and the discharge of the sand therefrom under the action of an air-currentdelivered into the box.

Figure I is a perspective view of my sanddelivery box. Fig. II is an enlarged longitudinal section taken through the box'. Fig. III is a transverse section taken on irregular line III III, Fig. II. Fig. IV is a perspective view of the side plate of the box looking at the inner side thereof.

1 designates the main member of my box, which has one closed side wall, two closed end walls, and a top, in the latter of which is an inlet 2, located near one end of the box, through which the sand to be delivered from the box is received. In one of the end walls of the member 1-namely, the wall adjacent to the inlet 2-is a jet-duct 3, and secured to said end wall is an air-conducting pipe 4, through which air is conveyed to the box to be discharged thereinto through the jetduct 3.

5 is an outlet-spout leading from the lower side of the main box member at the end opposite that at which the sand-inlet opening 2 and the air-duct 3 are located. This outlet-spout is adapted to have attached to it a tube or chute through which the sand is conveyed to the point at which it is to be discharged onto the railway-track rail.

6 designates a side plate or side wall member by which the side of the main box member which is not occupied by a wall is closed. This. side plate is provided upon its inner face with a rim 7, that is adapted to seat within the main box member at its open side, and it also bears at its inner side a guard 8 and a deflector 9, both of which parts are integral with said side plate. The deiiector 9 bears at its termination a threaded stem 10,

which is adapted to pass through the closed side wall of the box member 1 and which receives a nut 11, (see Fig. III,') by which the side wall 6 is held to the main box member. The guard 8 is located in a vertical position within the chamber of the delivery-box and immediately in front of the sand-inlet opening 2 in the top ofthe box, and said guard extends downwardly from the top of the box to a point sufficiently remote from the bottom of the box to provide a passage-way leading from the sand-inlet opening into the main portion of the box-chamber. The deiiect-or 9 is located considerably in advance of the guard 8 and extends upwardly from the bottom of the box to a point remote from the top of the box in order that a passage-way may be provided thereover into the portion of the box-chamber from which the sand is delivered to the outlet-spout 5. The main member 1 of the box is surmounted by a plate 12, that is provided with a neck 13, which contains a vertical opening that registers with the sand-inlet opening 2. The neck 13 is adapted to be connected to the receptacle in which the sand is carried, and the sand pasess therethrough to enter the chamber of the delivery-box.

14 is a slide-valve that is loosely iitted between the top of the main member of the delivery-box and the top plate 12 at the end of the box at which the sand-inlet opening 2 and the neck 13 are located. This slide-valve is provided with an aperture 15, that is adapted to be brought into registration with the openings 2 and 13 to permit flow of sand into the chamber of the delivery-box wall. The portion of said valve that is not occupied by said aperture is adapted to serve as a guard for preventing the ow of sand when the aperture 15 is out of registration with the openings 2 and 13. The slide-valve may be actuated in any desirable manner. When the sand enters into the chamber of my deliverybox through the inlet-openings 2, it moves downwardly into the box-chamber between the end wall adjacent to said inlet-aperture and the guard 8 facing said end wall at the opposite side of the inlet-aperture, and as the sand enters a portion of the chamber beneath said guard it is met by a blast of air entering the box-chamber through the duct 3 from the air-conducting pipe 4 and driven forwardly toward the defiector 9. The deflector 9 be- IOO IOS

ing located between the points of inlet ofthe I' sand and air and the spout 5, the sand is prevented rom taking a direct course through the box-chamber to the outlet-spout and is directed upwardly by said delector toward the top of the box to pass over the deflector in an even stream before entering the outletspout. It will be readily understood that in the ow of the sand under air-blast in the upward course over the deilector there is a constant tendency toward the creation of an eddy in the boxchamber, which causes the sand to circle rearwardly toward the sandinlet opening 2 but the entrance of the sand so directed into the inlet-opening is prevented by the guard 8, which, as previously stated, is located immediately in advance of the inlet-opening.

By providing the valve 14 I am enabled to shut off the liow of sand into the deliverybox whenever the sand becomes clogged therein in order that the ingress of sand into said box may be prevented during the cleaning operation. In accomplishing such cleaning operation it is only necessary to remove the side plate 6 of the box after removing thev nut ll applied to the threaded stem 10, which is carried by said side plate and passes through the side wall of the main member of the delivery-box. When said side plate is removed, the clogged sand in the box is readily dislodged from the box-chamber, and the side plate is then again replaced, the entire cleaning operation requiring but a short period of time and an extremely small amount oflabor.

I claiml A sand-delivery box consisting of a hollow main member having a sand-inlet, an air-inlet and a sandoutlet, and a detachable side plate having a delector and a guard integral therewith whereby said last-named members may both be withdrawn from said main member when said side plate is removed, substantially as set forth.
