SANDING DEVICE FOR POWER, VEHICLES.
Application filed June 2, 1926, Serial No. 118,348, and iuGermany July 8, 1925.
My invention relates to asanding device intended for use in connection with power vehicles,
box and the sand outlet nozzle of the same,
through the entire length of the sand box from the explosion motor of the vehicle into said outlet nozzle and conducting the motor exhaust gases into the said nozzle so as to cause .them to suck the sand out of the sand box and spray it upon the street or road just in front of the rear wheels, as is usually done. More especially, the invention consists in the combination of the sand box nozzle and the exhaust gas pipe with a shut-ofi' device located in the sand box nozzle between the free'end of said exhaust pipc'and the sandbox proper. The exhaust pipe is never closed by said shut-0d device, and the sand cannot enter into the sand outlet as long as the Only whenthe driver of the vehicle opens it by the intermediary of the means therefor provided, the exhaust gases of the motor exert a sucking action upon the sand present at and, may be, partly in, the sand box nozzle and carry it with them out of this nozzle. I g
I am aware of the existence of sanding devices where, if the street or road is to be sanded,'a certain portion of the motor ex' haust gases is conducted through the sand 'box in order to carry away a certain portion of the sand, there being therefor, a continually operating main gas exhaust pipe and a secondary gas exhaust pipe co-operating with the sand box and its nozzle, and there being required, moreover, a valve and the appertainingoperating members for connecting said secondary pipe with, and disconnecting it from, said main pipe, apart from-the means for opening and closing the roper, points of The chief drawbaci of this known sanding device resides therein that the sand is not always properly dry so that the portion of the exhaust gas actin upon it can'- not always carry away a oient amount of the sand. In contradistinction thereto there is, in my improved device, the sand heated continuously by the entire amount of "the hot motor exh'austgases whereby itis ,constantl kept dry and-m propel: condition for use. lBesides, while moist sand is subject to freezing in winter time, whereby the sand.-
ing deviee is rendered inactive and useless,
and comprising besides the sand said device is closed.
, sition,
this can never occur with my improved device.
The invention is illustrated diagrammatically and by way of example on the accompanying drawing on which Figure 1 is a longitudinal section through the improved sanding device, Figure ,2 a vertical crosssection in the plane 11-11 of Fig. 1, drawn to an enlar ed scale, Figure 3 a longitudinal sect-ion t irough a portion of the sand box nozzle, this figure showing a modification and being drawn to a still more enlarged scale. and Figure at shows a-section in the plane IV-IV of Fig. 3. i
In the drawing a denotes the sand box through which extends the exhaust gas tube 12, the first or inlet portion of which is funnel-shaped and may be provided with a sound-damping covering a of asbestos or the like. The exhaust branch (1 of the motor terminates into said funnel, as shown in Fig. 1, 6 denotes the sand box nozzle; the tube 6 extends into this nozzle and terminates there- 1n. The annular space or the tubular passage or channel between the neighbouring portions of the members 6 and e closed by a shut-oil device which does not in the least prevent the escape of the gases from the tube 6.
In the constructional form shown in Figs .1 and 2, the shut-oil device consists of a divided annulus f/g, of which the part f is stationary and the part 9 movable like a semi-c rcular slide which may be turned from the drivers seat by any suitable means, such as rods or a rod and a ro e or the like, and a (not s own) may be prothe part or slide 9 back into its position of rest i. e. its closing poafter an actuation. The actuating be connected with the braking spring or springs vided for moving means may means of the car, if desired, but the sanding device can be operated as well perfectly inde endently either before the braking in or er to prevent the car from skidding, or simultaneously withthe braking in order to assist this latter.
In-the modification shown in Figsf3 and 4 the annular channel or passage between the neighbourin portions of the tube 6 and the nozzle eis c osed by an annular member having in its lowermost portion an a erture closed ordinarily by a valve 'giattac ed by means of a fiat spring 71 to a. curved doublearmed lever ipivote'd at h vto the anf'. 'When the outer arm of this lever is turned in the direction of the arrow (Fig.
4), the valve 9 is,.withdrawn from the aperis drawn back into its former position, in
which it closes the aperture of the member f, by a helical spring 7'.
" I claim:
1. A standing device for power vehicles, com rising, in combination, a sand box and a sun outlet nozzle on the same, a motor exhaust gas pipe extending through the entire length of said box into said nozzle and being the continually used exhaust pipe proper of the motor of the vehicle, and a shut-off de'- vice located in the said sand box nozzle and being so designed as never to close the orilice of said sole exhaust pipe.
2. A sanding device for power vehicles, comprising, in combination, a sand box and a sand outlet nozzle on the same, a motor exhaust gas gipe extending through the en tire length of said box into said nozzle and being the continually used exhaust pipe proper of the motor of the vehicle, and a shut-ofi device located in the passage formed by the neighbouring portions of said sand box nozzle and said sole exhaust pipe and being so designed as never to close the orifice of this pipe.
3. A sanding device for power vehicles, comprising, in combination, a sand box and a sand outlet nozzle on the same, amotor exhaust gas pipe extending through the entire length of said box into said nozzle and being the continually used exhaust pipe proper of the motor of the vehicle, and, a shut-oi! vdevice located in the passage formed by the neighbouring portions of saidsand box nozzle and said sole exhaust pipe and comprising annpper stationary wall and a lower movable one adapted to be moved from the drivers seat so as to open and close an outlfet passage'for the sand, substantially as set ort 1.
4. A sanding device for power vehicles, comprising, in combination, a sandbox and a sand outlet nozzle on the same, a motor exhaust gas pipe extending through the entire length of said box into said nozzle and being the continually used exhaust pipe proper of the motor of the vehicle and a. shut-off device located in the passage formed by the neigh bouring portions of said sandbox nozzle and said sole' exhaust pipe and comprising a stationary-wall having an "aperture in its lowermost portion, a valve adapted to open and close said aperture, and means for actuating said valve, substantially as set forth.
5. A sanding device comprising, a sand box, a nozzle, means for establishing communication between the nozzle and the lffl terior of the box, and means for conveying a heated fluid through the box to heat the same and further. discharge the fluid into said nozzle to facilitatethe passage of sand to the nozzle and its discharge therefrom.
6. In combination'with an internal co'mbastion engine, a sanding device comprising a. sand box, a tube extending the length of the box and embedded in the sand, said tube having its inlet directly connected to the exhaust of the engine, and means for discharging sand in close proximity to the outlet end of said tube. I
In witness whereof I have hereunto set my hand. 7
