To all It'll/0111 it may (rm/c171.-

Be it known that we, FREDERICK .b. ROB- INSUN and JOHN McCain), citizens of the United States, residing at theyenne, in the county of Laramie and State ol Wyoming, have invented a new and ust t'ul 'lraclr-banrb ing Apparatus, ot which the following is a specification.

This invention rclatts to means carried by locomotives or traction-cars for delivering sand to the tracks whenever deemed desirable to prevent slipping of the wheels.

The principal object is to provide simple mechanism of a novel nature which will insure the delivery of sand, is readily adjustable to secure the proper llow oi the ntaterial, is not apt to become clogged or inoperative, but may be made to clean itself, and yet is so constructrd that the interior parts are readily accessible whenever it becomes necessary to examine or repair the same.

The preferred form of construction is illustrated in the accompanying drawings, Wherein- Figure 1 is a side elevation of a )ortion of a locomotive, showing the novel sanding mechanism applied thereto. Fig. 2 an end elevation of a portion thereof, shown on an cnlargi scale. Fig. 3 is a side elevation of the same. Fig. 4 is atop plan view. Fig. 5 is a sectional view on the line 5 5 of Fig. 4. Fig. 6 is a sectional view on the line 6 (5 oi Fig. 4.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

Whilethe invention in the present case is shown in connection with a locomotive. it is to be understood that it is not limited thereto, but is capable of successful use upon cars of any character having a motive-thud supply.

in the present embodiment the sand-box oi the locomotive is designated 7, and leading therefrom is a pipe 8, connected to the upper end of a casing t). This casing t) is divided into spaced depending legs it), each having iippositelywmending nipples it and t2. The lower ends oi the legs are closed by detachable plugs 13, threaded ihercinto. Sand-conducting pipes 14 (.Xttlitl l'rom the nipples 11 and have their discharge ends t5 arranged, respectively, in front and in rear ot' the driving-wheels oi the locomotive.

Plugs lti are threaded into the nipples 12, and screwed into the inner ends of these i plugs are nozzles 17, that project across the legs toward the nipplesll, terminating short oi" the same. Loch-nuts its are threaded upon the exterior portions of the plugs and are arranged to jam against the outer end ol the nipples t2. i\l tive-tlui l-conducting pipcs' it), connected with any suitable source ol'supply through the medium oi'- a common pipe ill, have 'alves 2] located at their juncture with the pipe 20. The other ends of these pipes are connected by bonnet-nuts 22 to couplings that are threaded into the outer ends of the plugs 16. Thus motive lluid supplied to the nozzles 17. The VOltime oi the llowis controlled, however, byturning valves or plugs 24, that are journalcd in the couplings 23, and have angularly-disposed passage-ways 25 and 26 thcrethrough, said passage-ways being of ditlerent diameters. The upper ends of the valves are provided with crossed notches 27 and 28 ot ditl'erent sizes to correspond to the passage-ways, and thus constitute indicators therefor.

Under ordinary conditions the smaller passage-ways 26 are in line with the bores through the motive-tluid-supply conduit, and consequently the larger passage-ways are cutout. It, therefore. motive tluid is ad mitted to either of the conduits 19, it will be projected through the nozzle 17, connected to such conduit, and the sand located within the casing will be expelled therefrom through the delivery-pipe 1st. hould the passageway 25 become clogged by the accumulation of sand therein under ordinary conditions, if the valve is reversed or given a hall-turn the passage-way will be cleaned automatically. for the l'orm'er discharge end thereof will then become the inlet end. ll.ho\\'evcr, this will not etl'ect the desired cl ansing action, a quarter-turp of the valve will bring the larger passage-way into line with the bore through the nipple, and a greater volume of air can then tlow through the nozzle. Thus two dil'- t'crcntpressures can be secured, and, more over, the nozzle can be readily adjusted toward and from the inlet. end at the sand-com ducting pipe H by screwing the plug lti into or out ol the casing, being readily held by the jam-nut 1h. it at. any time it becomes desirable or necessary to gain access to the interior ot the casing, it. is only necessary to remove either or both of the plugs 15 From the foregoing it is thought. that the construction, operation, and many advan tagesvof the herein-described invention vvill be apparent to those skilled in the art Without further description, and it will be under stood that various changes in the size, shape, 1

proportion, and minor details of cons traction may be resorted to without departing the spirit or sacrificing any of the advantages of the invention.

Having thus fully described our invention, What We claim as new, and desire to secure by Letters Patent, is

1. In sanding apparatus of the character set forth, the combination with a casing having an upper sand-inlet and an oil'set sanddischarge, of a motivdluid conduit, a coupling LllIGCtlil' connecting the conduit and casing on the side opposite the sand-discharge, and a reversible controlling-valve located in the coupling directly adjacent to the casing, said valve having a iluid-conihicting passage-way therethrongh, either end of which may be made the inlet of said passage-way by reversing the valve.

2. In sanding apparatus of the character set forth, the combination with a sand-conduit, oi' motivedlnirl-conducting means, con nections between the conducting means and conduit, including a coupling having an in lot and an outlet, a rotatable controllingvalve located in the conduit and. having pas sage-Ways oi" dill'eren t diameters therethroug that are movable into allnenient with the in,- let and outlet of the coupling, both ends of each passage-Way being movable into association 'With said inlet'ot' the coupling to secure the passage of the motive fluid in opposite directions through each passage-Way.

3. In a sanding apparatus of the character set forth, the combination with a sand-conduit, 0t motivedluid-conrhtoting means, connections between the cond cting means and conduit, including a coiipling having an inlet and an outlet, a rotatable controllingvalve located in the conduit and having anmlarlv-rlisposed passage-ways ol diil'erent iameters theretl'irough that are movable into alinement with the inlet and outlet oi the coupling, both ends of each passage-way being movable into association with said inlet of the coupling to secure the passage of the motive fluid in opposite directions through each passage-way.

4. In sanding apparatnsot the character set forth, the combination with a casing having a sand-outlet, and a sand-inlet,
