TRACK-SANDING- DEVICE.

Application filed October 3, 1908.

To all whom "it may concern:

Be it known that I, THOMAS N. LOCKE, a citizen of the United States, residing at Salem, in the county of Essex and State of Massachusetts, have invented new and use-: ful Improvements in Track-Sanding De-;

attached, a predetermined charge of sand.

will be distributed upon the track at a point immediately in front of the wheels of the car trucks.

A still further object of my invention resides broadly in the provision of a hopper adapted to contain a quantity of sand for distribution, and to locate beneath the said hopper a revoluble track engaging element or wheel for receiving sand from the hopper and discharging it upon the surface of the track as above described, and to further provide a novel form of agitator located within the hopper and adapted to be actuated upon rotary movement of the said element or wheel.

Another object of my invention is to provide a device of the class described. which will be provided with means whereby it may be attached toa car truck or to any other part of the car, and to further provide simple, effective and novel means for re.- taining the distributing wheel upon the track upon which it is to travel.

Other objects and advantages will be apparent as the nature of the invention is better set forth, and it will be understood that changes within the scope oftheclaims may be resorted to without departing from the spirit of the invention.

In the drawings, forming a portion .of this specification and in which like numerals of reference indicate similar partsin the several views :Figure 1 is a side elevation of the sanding device. Fig. 2 is a top plan view of the same. Fig. 3 is an end view of the same, and Fig. 4 is a detail longitudinal section taken through a portion of the device.

Referring now more particularly to the drawings, there is shown a sanding device consisting of a head member or block 1 bi- Specification of Letters Patent.

furcated horizontally at 2 and 3 for a purpose to be hereinafter explained. The head member -or block 1 is provided with a bracket 4 of yoke form which is preferably provided with a pair of horizontally disposed arms 5 adapted, in any suitable manner to be connected to the truck of a car or to any other desirable part thereof. A frame 6 is provided and is formed with a head or bearing 7 mounted in the bifurcated portion 3 of the head member or block and as illustrated the block or head memberhas connected thereto a vertically disposed pivot post or pintle 8 which is connected with the head 7 of the frame 6 so that the latter is free for, slight oscillatory movement. At the rear end the frame 6 is provided with a slot 9 in which is disposed a portion of a sand distributing element or wheel 10. The said distributing element or Wheel 10 is preferably revolubly mounted upon a shaft 11 journaled at its ends in bearing boxes '12 which extend downwardly from the frame 6. The said distributing element or wheel 10 consists of a v pair of spaced annular flanges or collars 13 and 14, the peripheral faces of which being arranged to travel upon the tread surface of a rail A. The said collars or flanges 13 and 14 are connected to each other by means of may be arranged to distribute upon the surface of the track, a predetermined charge of sand or the like. The collar or flange 14 is formed with a peripheral annular extension 17 which serves as a guide flange for the distributing wheel and eflectively holds thesame in itsoperative position upon the rail as will be readily understood.

, The frame 6 just described will be re ferred to hereinafter for the purpose of clearness as a main frame, and disposed immediately above the said main frame and in suitable spaced relation thereto preferably, is a supplemental frame 1.8 which has its forward extremity. operatively connected with the postor pintle 8 so that the frame is free for slight oscillatory movement. supplemental frame 18 is provided adj aoent to its rear end with an elongated slot 19 disposed immediately in line withthe slot 9 in the frame 6. A hopper 20 is carried by The the main frame and its lower reduced end extends downwardly below the slot 19 and is positioned immediately above the distributing element or wheel 10. The front and rear walls 21 of the said hopper have secured thereto bolts or suitable adjusting and clamping devices 22, the shanks of the said bolts or devices being disposed in elongated slots 23 formed in plates 24 mounted within the hopper. In View of the just described construction it will be apparent that the plates 24 are mounted for angular adjustment within the hopper so that the discharge end thereof can be reduced or enlarged at'the will of the operator so that the desired quantity of sand can be delivered from the hopper to the distributing element. The plates 24 in width are somewhat less than the distance between the flanges or collars 13 and 14 and the said plates have their lower extremities partly disposed in the said space between the flanges or collars.

The main frame has connected thereto in any suitable manner at a point preferably at the'rear of the hopper a post or standard 25 having pivoted thereto at its upper end a bracket 26. The bracket 26 carries spaced depending abutments or fingers 27 and- 28,; the latter having its lower extremity adapt- 1 ed for engagement with the rear extremity? of the supplemental frame, and the former has its lower extremity normally engaged with a stop or lug 29 which extends prefer- 5 times be held in its operative position, the

main frame. the bolts are extended through passages in the supplemental frame. As shown, the bolts are provided with washers K which are seated directly against the main frame to close the recesses in which the headed portions of the bolts are seated. Springs 32 are mounted upon the bolts and are confined between the washers and the adjusting nuts 31. Nuts 31 are also adj ustably mounted on the bolts and are disposed above the nuts 31 and they bear beneath the supplemental frame. On downward adjustment of the nuts 31 the bolts will be elevated slightly so as to cause the nuts 31 to be moved tightly against the supplemental frame, thus forcing the same against the finger 28. This construction is necessary in order that the device can be made to accommodate itself to tracks of different character or to one in which there may be certain imperfections, it being understood that it is essential that the wheel 10 or sand-distributing element is forced to bear against the track to insure a proper discharge thereto of the sand.

Arcuate guards 33 are carried by the main frame and extend partly around the dis tributing element and serve as means for obviating the premature dlscharge of sand.

The hopper has mounted therein an oscilla- I tory shaft 34 which carries a plurality of downwardly extending tines or agitating fingers 35, the said fingers being disposed in suitable spaced relation to each other and extend crosswise of the machine approximately the width of the hopper. The shaft 34 has connected thereto at one end a crank arm 36 with which is connected one end of a pitman or connecting rod 37 operatively connected with the distributing wheel as clearly shown in Fig. 1.

The head member or block 1 is provided with a horizontally disposed gear segment 38, the teeth of which meshing with those of a gear segment 39 pivotally mounted upon the main frame forwardly of the hereinbefore described hopper. The segment 39 has secured thereto a horizontally disposed arm 40, the ends of the said arm being secured to the forward extremities of helical springs 41. The rear extremities of the said springs are secured in any suitable manner to brackets 42 which extend upwardly from the sides of the main frame. Incident to the fact that the main frame is mounted to the head or block 1 so that it can be moved I horizontally, it will be appreciated that through the medium of the gear segments 38 and 39 and the springs 41 which are connected thereto, the main frame will at all automatically fed to the distributing ele- -ment or wheel 10. The pockets 16 formed in the distributing element convey the desired quantity of sand to the track and discharge it immediately in front of the wheels of the car trucks. It will be apparent that I may adj List the plates 24 to determine the desired discharge of sand from the hopper to the distributing wheel. v

A device of the'character described is extremely simple in construction, may be applied to cars of the well known type and is automatically driven by reason of the fact thatit is carried directly by the car and that the distributing wheel rides upon one of the rails. The operation of the distributing wheel not only discharges upon the track the desired quantity of sand, but through the connections her-einbefore describedbetween the oscillatory shaft 34 and the said distributing wheel, it is obvious that the 1 agitating fingers will be operated simulta- Copies of this patent may be obtained for neously with the operation of the-wheel so that sand within the'hopper will be thoroughly loosened whereby it may be properly discharged to the distributing wheel.
