TRACK-SANDER.

SPECIFICATION forming part of Letters Patent No. 757,416, dated `April 12, 1904.

Application iiled February 4, 1903. Serial No. 141,820. (No model.)

To 1J/Z whom it muy concern.:

Be it known thatI, CHARLES V. ROTE, a citizen of the United States, and a resident of Lancaster, in the county of Lancaster, State of Pennsylvania, have invented certain Improvements in Track-Sanders, of which the following is a specification.

This invention relates to improvements in that class of devices designed for sanding the 1o tracks of railways` and they are more particularly applicable to electric and other motor cars; and the objects of these improvements are, first, to regulate the amount of sand fed to the rails; second, to provide a uniform discharge of sand; third, to cause a positive discharge, and, fourth, to obtain these results whether the sand be wet or dry. I attain these results by the mechanism illustrated in the accompanying drawings, in which- Figure l is a side elevation of'a sander embodying my invention, the sand-box being shown in an elevated position; and Fig. 2, a

similar view, but illustrating the sand-box in an operative position. Fig. 3 is a top plan view of the shaker'- frame and of the operative parts connected therewith; Fig. 4, a bottom perspective view of the sand-box, and Fig. 5 a longitudinal vertical section of the sandbox. Fig. 6 is a top perspective view of the 3o shaker-frame, and Fig. 7 a top perspective view of the bearingplate of the shaker-frame.

Fig. 8 is atop perspective view of a modified construction of the shaker-frame; Fig. 9, a bottom perspective view of a modified con- 3 5 struction of the sand-box, and Fig. 10 a side elevation thereof shown in an operative position. Fig. 11 is atop plan view of the modified construction of the shaker-frame and of the operative parts connected therewith; Fig. 12, a top perspective view of the modified construction of the shaker-frame and .of the brush-bar engaged therewith; Fig. 13, a front View of the modified construction of the sandfboX, and Fig. 14 a rear elevation thereof and of its pivoted connection. Fig. 15 is a View of a swinging or hinged discharge-pipe attached to the vibrating platform, and Fig. 16 a partial rear View of the sander shown in Fig. 1.

Similar numerals indicate like parts throughout the several views.

For the purposes of this specification the discharge end of the sand-box will be called the front and the other end the reaix In the accompanying drawings, referring to Figs. 1 to 7, inclusive, 1 indicates the floor of a car, partially cut away, as shown. 2 designates a sand box, widening from its closed or pivoted end 3 to its delivery end 4..

The front wall 5 of the sand-box slopes backward from its lower to its upper edge, and between said lower edge and the bottom 6 of the sand-box is a discharge-opening 7, wherethrough the sand is delivered to the vibrating `platform 8, `to be more fully described. The

uppervend of frontwall 5 bears against top plate 9, extending about half-way back 1over the sand-box and leaving an opening `through which sand is fed to said box. Inside of front wall 5 of the sand-box is a deiiectorplate 10, having the ends secured to` side walls 11 of the sand-box by removable pins 12. It will be noted that the deflector-plate 1Q is located a short distance from the front wall lof the sand-box and that said defiector-plate terminates at its lower edge a short distance above the bottom edge 4of the front wall 5. The deliector-plate thus keeps the sand from coming in direct contact with the main portion of the front wall 5 and only a small portion of the 4sand touches the said. front wall. Therefore the sand is prevented from chokingV or congesting in the discharge-opening 7. This has the effect of' lengthening the discharge space or opening in a horizontal direction and prevents the sand from packingl adjacent to the point of discharge. Therefore the agitation or shaking of the sandfbox as a whole insures the loosening of the sand andthe proper discharge thereof upon the platform into the funnel and pipe. Y

The shaker-frame comprises a `curved crosspiece 13, having on the ends thereof parallel and horizontally-disposed arms 14, provided with rack bars or teeth 15 on their outer ends, and on said arms back of the rack-bars are elevated bearings 16, having on their front edges ribs or flanges 17, all for a purpose to be described. On the back of cross-piece 13 are two lugs 18, between which is hinged an end 19 of lever 20, that passes through a slot 21 in the bearing-plate, to be described, and in the base-plate 22, to which said bearingplate is secured, and on the under Aside of cross-piece 13 are lips 57, that engage ribs on the bearing-plate and serve to guide the movement of the shaker-frame. Lever 20 is fulcrumed between two hangers 23, attached to base-plate 22, and has its lower end connected by a rod 26 with hand-lever 24, fulcrumed in a standard 25 on the car-floor.

27 indicates the bearing-plate of the shakerframe, shaped substantially as shown and provided on its rear end with standards 28, having transverse grooves 29, and on the sides of the bearing-plate parallel with the front of slot 21 are ribs 30, the bodies of which inoline slightly upward from the inner toward the outer ends, where they abruptly rise with curves to elevated points 31. Near the rear end of the sand-box andon the bottom thereof are hinge -lugs 32, that loosely engage grooves 29 of the standards 28` whereby the discharge end of the sand-box is adapted to be reciprocated about the pivots formed by the engagement of thehinge-lugs with said grooves. Secured to and beneath the front end ofthe sand-box are brushes 33, that when said sand-box is in an operative position normally engage rack-bars 15 of the shakerframe, as seen in Fig. 2.

In operating to sand-a track hand-lever 24 is moved back and forth just enough to keep brushes 33 in engagement with rack-bars 15, whereby a reciprocating motion is given the sand-box about its pivots or hinges. As the sand used for the purpose contains much loam and other impurities and as it is generally more or less damp, it clogs the discharge-openings of the majority of sanders and the delivery is apt to be irregular and spasmodic, amounting to little or none at times and then again shooting out in lumps and masses. This difficulty is overcome by my construction just described, as each upward movement of the front end of the sand-box is with a sudden jerk, loosening up the sand, and each downward movement of said sand-box is arrested with another jerk, throwing the sand out upon platform 8. The discharge of the sand is Vstill further promoted by the shape of the sand-box, which spreads from the rear to the front or discharge end thereof, and by the construction of said platform 8, which is composed of some resilient material, and so has a vibrating motion of its own about the line of its connection with the sand-box, as shown somewhat exaggeratedly by broken lines 34, Fig. 2. The sand may pass over the outer edge' of platform 8 when said platform is connected as shown in Figs. 4 and 5; but preferably said platform has a funnel 42 attached to Y rack-bars are at the same time thrust so far.

forward that brushes 33 are compelled to travel up the fronts of bearingsv 16 and to and over ribs 17 thereof, behind which they rest on said bearings, and the sand-box is in a position to prevent the automatic discharge of sand.

In Figs. 6 and 8 to 12, inclusive, is shown a modification in the application of the principle illustrated in the mechanism just described. Here the sand-box is vibrated horizontally, and for that purpose the teeth of the rack-bars 37 are placed on the inside and facing edges of arms 38 of the shaker-frame 39, and a brushbar 40 is secured to the bottom of the sandbox and has a brush 41 extending down between and engaging at the same time the teeth of both said rack-bars 37, as shown in Fig. l2. Motion is communicated to shaker-frame 39 precisely as is set forth for the first-described construction, and the front end of the sandbox is also thrown up into its inoperative position in the same way as in said first-described construction; but by reason of the sand-box having both a vertical and a horizontal movement the construction of the hinge thereof is modified. A standard 43 is located on the rear end of bearing-plate 44 and has therein a vertically-disposed socket, as shown by broke-n lines 45 in Fig. 14. This socket is engaged by a pivot-pin 46 on a stud 47, formed with a cross-bar 48, having journals 49, that loosely engage hangers 50 on opposite sides of the bottom of the sand-box. j

To facilitate the movement of sand from the rear to the front of the sand-box, the rear end of base-plate 22 is elevated and rests on a block 51, and sidewise movement on standards 28 is prevented by lips 52 on hinge-lugs 32, which lap the inner faces of said standards 28, as seen in Fig. 16. The mass of sand in the sand-box is broken or disintegrated by the lower end of deiector-plate 10, which descends somewhat below a line (shown by broken line 53) drawn from the top ofthe rear wall 54 to the outer end of vibrating platform 8, which is somewhat uptilted to prevent a continuous flow of sand therefrom. To prevent the accumulation of sand on the walls of pipe 36, a cleaning-chain 55 may be attached to nozzle 35 and extended down into said pipe 36, or stationary pipe 36 may be dispensed with and a hinged or vibrating pipe 56 be directly attached to nozzle 3 5, as shown in Fig. 15, or

said pipe `56 may befdirectly attached to the outer edge of vibrating platform 8.

I do not coniine myseliI 4to thedetailsiof construction herein shown and described, as itis obvious that many kalterations :may be made therein .without departing trom the principle and scope of ymy invention.
