HOWARD HAWTHORNE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR 0F ONE-HALF TO WILLIAM W. EVANS, OF HAMILTON, VIRGINIA.

TRACK-SANDING MECHANISM FOR TROLLEY-CARS AND LOCOMOTIVES.

Specification of Letters Patent.

Patented June 18, 1912.

To all whom it may concern:

Be it known that I, HOWARD HAWTHORNE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Track- Sanding Mechanism for Trolley- Cars and Locomotives; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in track sanding mechanism for trolley cars, and locomotives, and relates more particu larly to the construction and relative arrangement of the parts of such mechanism.

The object of my invention is to provide a device comprising two compartments, one for the storage and the other for the dis charge of sand, each compartment being provided with valve mechanism so constructed and arranged that the openings between the storage and discharge compartments, and the opening through which sand is discharged onto the rail ,will be simultaneously governed and controlled.

A further object of my invention is to provide a sanding device in which the storage and discharge compartments are superposed and combined in compact form and in which a single valve actuating shaft serves to operate the valves in both compartments.

A further object of the invention is to provide both the storage and discharge compartments with valves and valve actuating mechanism and with means for compensating for the wear of both valves and their seats.

A further object of the invention is to provide a simple, economical, durable and efficient construction of parts, which will occupy very little space on a car and is adapted for ready and easy operation.

With these objects in .view my invention consists in certain features of construction and combinations of parts aswill be hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation of my improvement; Fig. 2 is a vertical section; Fig. 3 is a plan view of the bottom of the storage receptacle; Fig. 4 is a plan view of the 0scillating valve for regulating the discharge of sand from the storage receptacle into the discharge receptacle; Fig. 5 is a transverse section of said valve; Fig. 6 is a plan View of the bottom of the discharge receptacle; Fig. 7 is a plan view and Fig. 8 is a transverse section of the valve used in the diS- charge receptacle; Fig. 9 is a view in plan of the actuating arm, and Fig. 10 is a view illustrating one arrangement of mechanism for actuating the valves.

1 represents the sand storage receptacle and 2 is the discharge receptacle both of which may be made of sheet or cast metal and are preferably cylindrical in form.

Storage receptacle 1 is provided at its upper end with an outwardly projecting annular flange 3 having holes 4 formed therein through which bolts are passed for securing the receptacle to the underframe of a car body at any desired point thereon. The lower end of receptacle 1 is constructed with an inwardly projecting annular flange P, to the underside of which, is secured by bolts 5, the outwardly projecting flange 6, of the valve seat 7 of the storage receptacle.

Discharge receptacle 2 is secured at its upper end to the downwardly projecting flange 8 of valve seat 7 by means of screws 9, and to thebottom 10 is secured the discharge funnel 11, which is constructed and arranged to insure the discharge of sand on to the traclerail.

12 is a valve actuating shaft, which is journaled near its upper end in a hole 13 formed in the center of the valve seat 7. To the upper end of the shaft 12 is secured two oscillating valves 13, 13, each of which is sector shaped and they are connected together by a central hub 14 which is mounted upon the upper end of shaft 12 and secured thereto by the transverse pin 1 1 and nut 15. The valve ,seat 7 is provided with two sector shaped ports 16, 16, which are simultaneously opened and closed by the oscillating valves 13, 13. Each of these valves is provided on its upper surface with upwardly project-ing prongs 17 which ongage and stir the sand as the valves are actuated and thereby prevent the sand from clogging and cause it to flow freely t-hrouglr the ports 16 into the discharge receptacle 2.

18 is a sector shaped oscillating valve seated upon the bottom 19 of the discharge receptacle and arranged to open and close lbs the hub 22 of the valve and through the shaft. This valve is constructed with up wardly projecting prongs 23 which serve to stir up the sand in close proximity to' the valve when the latter is actuated and prevent the sand from clogging and insure r and largely assists in maintaining its contents dry and in conditlon to be readily disits free escape through the port 20.

24 is a coiled spring which encircles the lower projecting end of shaft 12. The up er end of the spring is seated against a was er 25, the upper surface of which engages the bottom plate of the discharge receptacle while the lower end of the spring is seated upon the washer 26 which is supported by a nut 27. By adjusting the nut the tension of the spring may be regulated and varied as desired. lVhile the weight of the two valves and their actuating shaft, all tends to retain the valves against their seats, the coiled spring exerts its force to cause the valves to snugly fit against their seats and preventstheir being displaced due to the jolting'or jarring of the car over rough tracks, and it also adjusts the valves to compensate for their wear or that of their seats. Shaft 12 is provided with a squared lower end 28 to which is secured the inner end of the actuating arm 29 which is constructed with a square hole 30 within which is inserted the squared end of the shaft, the parts being secured in place by means of a transverse locking pin 31. A stop pin or lug 32 limits the extent of movement of the arm 29. The arm 29 may be actuated by the motorman by any suitable mechanism. I have illustrated one construction and arrangement of mechanism for this purpose which consists of a vertically movable treadle 32 located above the platform of the car and within easy reach of the motorman and with which is connected a rod 33 which extends downwardly through the platform and is pivotally connected with one arm 34 of a bell-crank lever, the other arm 35 of which is connected by a rod 36 with the outer end of the actuating arm 29. A spiral spring 37 interposed between the treadle and platform serves to retain the treadle in its raised position. Then the treadle is in its raised and normal position the discharge valve 18 will be closed and the valves 13, 13 in the storage compartment will be open, and hence the lower and discharge compartment will always be kept filled with sand. I Vhen it is desired to sand the track, the'motorman by forcing the treadle downwardly, transmits an oscillating movement to shaft 12 which operates to close the valves 13, 13 and opens the discharge valve 18 thus permitting the sand to escape and flow upon the track rails for any desired length of time and during this period preventing the sand from flowing from the storage compartment into the lower and discharge compartment.

My improved device is exceedingly com- 2 act sim 1e and economical in its construction and arrangement of parts. By having the storage receptacle located immedlately "over. the discharge receptacle and its walls secured thereto, it shields the contents of the discharge receptacle from the weather while a single coil spring prevents either one of the valves from being jarred from its seat by the jolting or jarring of the car, and also causes the valves to automatically adjust themselves to their seats and thereby compensate for wear.

Itis evident that slight changes might be made in the construction and arrangement of the several parts of my improvement without departing from the invention. I would have it understood that I do not re strict myself to the particular construction shown and described.

Having fully described my invention what I claim as new and desire to secure by Letters- Patent, is z 1.
