TRACK-SANDING APPARATUS.
No. 930,oo8.'
Specification of Letters Patent.
Patented Aug/3, 1909.
Application filed March 15, 1909. Serial No. 483,458.
I This invention relates to track-sanding apparatus of that type particularly designed for use in connection with street-cars."
Inasmuch as the sand-receptacle is necessarily" carried by some portion of the car body, ithasheretoforebeen found diflicult to direct the sand therefrom and on to the track while the car is traveling around a curve, because at such time the relative positions of the wheels and the car body change and any sand-dischargin spout extending from the bod is thus shifled out of position above the rai s.
One of the objects of the resent invent-ion is to provide means where y the sand may be directed ositively on to the rails irrespective oft e relative positions of-the car- 'body and the trucks, flexible means being utilized for conveying the sand from the receptacle to the discharge spout.
A further object is to provide connections of this type particularly designed for use in connection with pneumatic sanding devices.
Vith these and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinaftermore fully described and pointed out in the claim-Sr s In the accompanying drawing the preferred form ofthe invention has been shown. Qaid drawing is a view showing the sanding apparatus in section.
eferring to the drawing by characters of reference A designates a portion of a car body and Ba portion of a car truck, and secured to the truck is a discharge spout 1 preferably substantially conical in form and having its small end lowermost and provided with an outlet 2 which is arranged directly above the rail on which the adjoining wheel of the car is mounted. This spout 1 is secured tothe truck in any referred manner, preferably by means of a racket 3 which serves to hold the spout rigidly connected to the truck. I i p A sand receptacle 4 is located atany su table point upon the car body'and has a discharge nozzle 5 extending through one wall thereof, this nozzle gradually tapering from its inner to its outer end and being curved from end to end, the intermediate portion of the nozzle'being elevated above its ends and the large or receiving end of the nozzle .being inclined with relation, to the bottom of the car body. This receiving end of the nozzle which has been indicated at 6 is disposed in front of the discharge end of an air nozzle ('tormed at one end of a tube 8 which extends through one wall of the receptacle 4, said tube being bent downwardly upon itself so as to direct a jet of air into the receiving end of the nozzle 5 as indicated by arrows n the drawing. The tube 8 is designed vto be attached to any suitable air reservoir which can be located at any desired point upon the car structure and in which air may be compressed in any preferred manner. It is of course to be understood that the discharge of air' into the nozzle 7 may be controlled by means of any suitable valve mechanism, which however constitutes no part ofthe present invention and it is not therefore illustrated.
'T he small end of the nozzle 5 is extended through the bottom of the car body A and has a flexible tube 9 attached to it, said tube extending downwardly and having its "lower end loosely suspended within the spout 1. The tube extends a sufficient distance into the spoutto remain therein during all relative movements of the car body and the truck. h
In using the apparatus herein described the receptacle l is filled with sand and air under pressure is directed through the tube 8 to the nozzle 7. A jet of air is thus discharged into the large receiving end of the nozzle 5, the discharge being of such velocity as to drive a portion of the sand into the nozzle and thence downwardly through the tube 9 to the spout 1. Inasmuch as the spout is tapered downwardly toward its outlet 2 it will be apparent that considerable resistance will be offered to the downward move,
tion and arrangement of the parts without advanieqes of the invention.
