To all whom t may conce/m:

it known that l, LYMAN C. Josnris,

dr., o. citizen of the United States, residingl et Schenectady, in the county of Schenectady@ State of New ilerlr7 lieve invented certain new :ind useful linproveinents in Distributing Devices, oi' which the following is zrspccicetion.

My invention relates to u distributing device. and purticulnrly to such device do signed ilor the sending of ruilwuy trocls.

lieuoi devices ure commonly employed in locomotives e. d curs for the rczuily applicutioo. send, stored in convenient receptaclc7 to the trucks, in order 'to increase the illrictionel grip olf the whce The receptocles employed `for the send are usually constructed with u. hopper-shaped bottone and when thequzintity of send is considerable, or the send is dinnp, there is e tendency toward cziking or packing which prevents or hinders the operation of the device. l lieve.I accordingly, so constructed my device that it will operate successfully under conditions of service. und the object of iny invention is to de rise :i distributin f.;m device7 adopted ttor use es e locomotive sonder, which shell be cer tuin in operation and. of e durable construction,

Another object of roy invention. is 'to de- {ir-operated device of this type, lor proventingF the introduction of sund to the motor bearings. Still another object is lo construct u device of the type described so that wasting" of the sand will not result from the vibration of the locomotive.

l preferably construct my device in the form of e.. costing capable ol" :ittaclnnent to desired type ol? rceepteclc. i hoppershoped uppeil port-ion lies :in outlet in one side near the lower end. Conununicu ino with this outlet is e passageway lending in's; in :i general horizontal direction over :i trainsvcrse ridge, formed by :no uiiwurd bend, und thence downwardly for connection to :i hose or pipe. Substantially opposite the outlet is u. beni-inn* for o, plunger which is provided with un agitator ond is movable toward :ind away from the outlet. 'for the purpose of pushing' the sund throi'zogh 'the pessugewiiy und ucross the ridge therein. ll' then provide :i motor 1for operating` the plunder. und preicrubly this motor will toko 'storm of n. iluid operated reciprocatin fe. which Specification of Letters Patent.

will connnonly be operated by compressed oir. A nozzle is arranged in the vertical portion ci the outlet passageway, beyond the ridge, und an un' passageway provided connccting the exhaust of the motor with this nozzle. A trop cli-.unber ,is or 'ringed inten mediate the plunger hearing; in. the hopper shaped costing and the bearing for the plungrn' in the motor, und this chinnber cour' inunicntes :it its lower side with the air pzisou showing.; the complete device :is attached to onto receptacle. Figs. 2 und 3 are cross-sections of the motor, showing; the piston in various positions.

The larger portion. ot niy device will preferably be construetedl in the forni oit en integr-ul eusting., which is shown es provided with e hopper l0 designed for attachment to the lower end ol :my forni of receptacle fi.. At the lower end of this hopper e slight recess ll is provided, and at the side of this recess .is the outlet lf2. Extending in e subs'tzintiully horizontul direction. frein the outlet is u pussugewoy 13. ond this passageway is provided "ith n ridge ifi extending trans'- `vcrscly ther-co l. d nd conveniently formed by un upward bend of the passageway. Beyond this ridge the passageway proceeds in ai general downward direction. und is adept ed nt its lower end l5 for connection to 2i hose or pipe. Substentio. ly opposite the outlet lil the recess ll is provided with o bearing 'i6 for the horizontully rcciproceble plunger 17, which may be nioved towsnd and :iwuy from the outlet opening, thereby pushingr the sund through the passageway i3. llliis plunger is provided with an agitator 18 extending;- opwnrdly into the hopper l0 to prevent culling;r of the sund. ln the yerticel portion of the pussuygcwuy 13 u. nozzle l@ allows for the introduction ol' n. blast oi' air., which is led to th:` nozzle by ineens of the passageway 20.

For the reciprocetion of the plunger, ll provide :i suitable motor 30. which shall preferably be constructed as e, fluid-operated device, and will comprise mein cylincer 3l within which the piston ref ciprocutes, 'this piston being here shown :is integrally connected with the plunger l?. 'lflie piston is constructed with :i port 33 n ruiming longitudinally i'zhereof, uns. in "she o, hurler 3l exhaust port connected vwith he pessiiswayv 20. As is here shown, fhis inoaor muy he clellechehly se cured, hf; ineens of bolts, "so 'the mein cestng. Deiuchahly seoureii to lie cylincler 4a Valve 85 provided Wih en inlet ln this easing e volvo 37j mounted on ain egiension 38 of the piston, conrols the ediniss'oyn oc nir to one side or lie other of 'she pis onJY i ovenien of this valve, which consiruclefl inne forni of e perforeeol disk, is limited. by ineens of shoulders 39 and 3S" on the piston extension, und by e niet llie guslies bolted heimeen 4she cylinder 3i one?. the valve casinginerinediee he hearing i6 in the mein casting :Jul she hearing for the plunger in the cylinder of lhe motor, l have provided s trap chuniher l() which communicues at its lower end wilsh she air passageway 20.

in operation, when air is supplied to lie motor Lhe plunger i7 will he reciproceecl within the recess at v':he lower end of the hopper l0, and iherehjvy inermi/aently push she send through lie outlet ino 'the pusssgeway 13. By continued movement of the plunge@v the send will be forced pesi: he ridge lil: in the passageway and will drop by gravity to the outer end thereof;
