SAN D-INJECTOR FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 557,725, dated April '7, 1896. Application filed October 19, 1898. Renewed December '7, 1895. Serial No. 571,443. (No model.)

To all 20. 2.0711 it may concern.-

Be it known that I, HUGO TIRMANN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Sand-Injectors for Locomotives, of which the following, with the accompanying drawings, is a specification.

The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the inven tion may be used.

In said annexed drawings, Figure I represents a side elevation of my improved sandinjector for locomotives; Fig. II, an axial section of the same; Fig. III, a transverse section on the line III III in Fig. II; Fig. IV, a transverse section on the lines IV IV in Fig. II 5 Fig. V, a perspective detail view of the hooded diaphragm or valve-seat; Fig. VI, a face view of the discharge side of said diaphragm or valve-seat, and Fig. VII a face view of the valve.

A'casing A is formed with the general outline of a pipe-elbow and has a neck a, by means'of which it is attached to and connects with the sand-box of the locomotive, and a neck a, to which is attached the upper end of a Y-coupling B, to the branches of which the sand-pipes for the drive-wheels at that side of the locomotive are attached The neck a and the upper end of the Y-coupling are each formed with a vertical partition, respectively, a and Z),'which thus divide the neck and the coupling to distribute the sand which passes through the casing to either of the sand-pipes.

At the junction between the horizontal and vertical portion of the casing is secured a diaphragm or valve-seat C. Said diaphragm has an opening a in its upper portion and an opening 0 in its lower portion. A curved hood 0 overhangs the upper opening of the diaphragm at the receiving side of the same. A

partition 0 extends vertically from the receiving side of the diaphragm toward the inner face of the hood, and said partition is extended in a wing a the lower edge of which follows the curve of the casing and which wing extends above the lower edge of the hood. The receiving end of the casing is thus longitudinally and vertically divided by the partition having the wing, said partition corresponding in its position in the casing with the partitions in the neck a and the Y-coupling.

A valve-disk D has a seat against the discharge-face of the diaphragm, and said valvedisk is formed at its upper portion with an opening (Z, which may be brought to register with the opening 0 or c in the diaphragm by rotating the valve-disk upon its center. The valve has a central stem (7, to the outer end of which is secured a stem (Z of a controllinghandle D. The stem passes through a detachable screw-cap A upon the end of the casing. A sleeve 6 fits upon the stem of the valve and has two diametrically opposite wings e, which may register with the partition of the diaphragm. A head E is secured upon said sleeve and may rotate within the horizontal portion of the casing, so that the sleeve, wings, and head may rotate with the valve when the latter is rotated by means of the controlling-handle. A spring F is coiled around the controlling-stem (Z and bears against the head and the screw-cap, thereby forcing the valve to a seat upon the diaphragm Air-pipes g are suitably connected to an airpump or other source of compressed air, and said air-pipes enter the sides of the casing and are provided with nozzles g which proj ect into the spaces between thedlood and the diaphragm, one on each side of the partition, and points downward. Screw-plugs a are preferably inserted through the sides of the casing at points opposite the nozzles, so that they may receive all the wear caused by the air-blast and consequent movement of the sand and may be renewed whenever worn out. Neeedle-valves g are provided to regulate the air-blasts passing through the nozzles. Air-pipes g pass from the couplings Got the air-pipes through the sides of the casing and one down through each of the branches of the Y-coupling, so that any'clogging of sand in the branches of the coupling maybe removed by air-blasts through said pipes.

An air-nozzle H extends through the sides of the vertical portion of the casing opposite the hood and has a pipe connection 71- to the air-pipe coupling G, and said nozzle is controlled by a valve h, so that air-blast may be admitted against the convex face of the hood to clear away any sand which may have accumulated upon the hood.

By means of the herein-described device sand may be applied at either one or more drive-wheels of a locomotive and may be applied in small quantities by means of the airjets or in large quantities by allowing the sand to directly run through the device. By turnin g the valve the opening in the same may be brought to register with the upper or lower openings in the diaphragm or to register with the openings at one side or the other of the vertical partitions. Air-blast to the nozzles may be suitably controlled by valves upon the air-pipes. If the sand-pipes should for some reason or other become clogged, air-jets maybe admitted into them by the branch airpipes g and sand which accumulates upon the hood may be blown away by an air-blast from the end nozzle H.

Other modes of applying the principle of my invention may be employed for the mode herein explained. Change may therefore be made as regards the mechanism thus disclosed, provided the principles of construction set forth, respectively, in the following claims are employed.

I therefore particularly point out and distinctly claim as my invention 1. In a track-sanding device, the combination of a casing provided with an inlet constructed to communicate with the sand-box and with an outlet having two branches constructed to communicate with sand-pipes, Vertieal and longitudinal partition in said casing dividing the latter into two longitudinal chambers each communicating with a sand-pipe branch, a diaphragm in the casing transverse to the partition and formed with an opening and a valve against said diaphragm formed with an opening and constructed to form or close passage through the diaphragm at either or both sides of the partition, substantially as set forth.

2. In a track-sanding device, the combinaiion of a casing provided with an inlet constructed to communicate with the sand-box and with an outlet having two branches constructed to communicate with sand-pipes, vertical and longitudinal partition in said casing dividing the latter into two longitudinal chambers each communicating with a sand-pipe branch, a diaphragm in the casing transverse to the partition and formed with an opening, air-blast device constructed to raise the sand in the inlet portion of the casing, and a valve against said diaphragm formed with an opening and constructed to alternately form or close passage through the diaphragm at either or both sides of the partition, substantially as set forth.

3 In a track-sanding device, the combination of a casing provided with an inlet communicating with the sand-box and an outlet having two branches communicating with sand-pipes, vertical and longitudinal partition in said casing dividing the latter into two longitudinal chambers each communicating with a sand-pipe branch, a diaphragm in the casing transverse to the partition. and formed with openings in its upper and lower portions, air-blast device constructed to raise the sand in the inlet portion of the casing, and a valve against said diaphragm and formed with an opening and constructed to be turned so as to bring its opening to register with the openings in the diaphragm, substantially as set forth.

4. In a traeksanding device, the combination of a casing provided with an inlet communicating with the sand-box and an outlet communicating with the sand-pipes, a diaphragm located within said casing and provided with a hood and a vertical partition toward the inlet, a rotatable valve, and a head provided with wings, substantially as set forth.

5. In a track-sanding device, the combination of a easin g having an inlet and an outlet, a stationary valve-seat having a hood and a vertical partition toward the inlet, a rotatable valve, a head formed with wings, and an airnozzle beneath the hood, substantially as set forth.

6. In a track-sanding device, the combination with a casing having an inlet communieating with the sand-box and an outlet communicating with the sand-pipes, and mechanism within said easing for controlling the passage of sand through said casing, of air-nozzles entering said casing to provide air-jets to loosen the sand in the same, and pipes connected to said air-nozzles and extending through said easing into the upper portions of the sand-pipes, substantially as set forth.

7. In a track-sanding device, the combination of a casing having an inlet communicating with the sand-box and an outlet communieating with the sand-pipe, a transverse diaphragm in said casing having an opening in its upper portion and an overhanging hood toward the inlet, an air-nozzle beneath said hood, and an air-nozzle directed toward the side of the hood which faces the sand-inlet, substantially as set forth.

8. In a track-sanding device, the combination of a casing containing the sand and having an outlet for the same, an air-jet nozzle entering said casing, and a wear-plug inserted at a point directly opposite the air-jet nozzle, substantially as set forth.

In testimony whereof I afiix my in presence of two witnesses, this May, 1893.
