SANDER.

SPECIFICATION forming part of Letters Patent No. 708,929, dated September 9, 1902.

Application filed .Tune l0, 1902. Serial No. 111.064. (No model.)

To all when?, it may concern:

Be it known that we, SAMUEL T. SIMMONS and WALTER T. MOORE, citizens ofthe United States, residing at Columbus, in the vcounty of Franklin and State of Ohio, have invented new and useful Improvements in Sanders, of which the following is a specification.

Our invention relates to Sanders; and the object of the sameA is to construct a device which will uniformly distribute wet, dry, or

crusted sand on the rails beneath a car without choking up or wasting the sand.

The simple and novel construction employed by us in carrying out our invention is fully described in this specification and claimed, and illustrated in the accompanying drawings, forming apart thereof, in Which- Figure 1 is a vertical section of our device. Fig. 2 is a horizontal section on the line 2 2, Fig. 1. Fig. 3 is-a detail perspective of the vertical shaft and its blades. Fig. 3 is a detail ot' the discharge-blades. Fig. 4 is a detail of the gearing. Fig. 5 is a detail of the cut-off blades.

Like numerals of reference designate like parts in the different views .of the drawings.

The numeral 1 designates a sand-box of appropriate size, the upper portion 2 being cylindrical and the lower portion 3 being hopper-shaped. An agitator or stirrer is mounted in the box 1 and comprises a vertical shaft 4, having a series of blades 5. The shaft 4is journaled in a cross-bar 6, extending transversely the box, and in an aperture 7 in the bottom 9 of the box. A crank 8 is keyed on the upper end of the shaft 4 and serves as means for operating'the device. The blades 5 are beveled to a knife-edge to adapt them to out through crusted sand. The bottom 9 is apertured at 91L to permitthe outliow of sand, and a hub l0 is keyed on the shaft 4 at a point just above the bottom 9 and carries two oppositely-extending blades 1l,which we will term discharge blades. These blades 11 are beveled to a knife-edge 11a and are set at an angle to the bottom 9, so that they will catch the sand, raise it up, and permit it to dow off of the back, thereby loosening it up and preventing it packing on the bottom 9. Also keyed on the shaft 4 and located beneath the bottom 9 and extending parallel to the discharge-blades 11 is a cutoff'12, comprising oppositely-extending arms 13, the upper faces of which bear on the under side of the bottom 9. By making a mark on the rim of the box 1 in aliuement with the apertures 9a the crank can always be set when stopped so that the arms 13 will cover the discharge-openings 9C. A slide 14 is mounted in guides 14 to also serve to cut off the discharge of sand. This is useful when the crank 8 is dispensed with and the shaft 4 is driven from some source of power instead.

Mounted just beneath the bottom 9 and secured thereto is a casing 15, containing two chambers 16, in which are mounted two feeders comprising shafts 17, bearing blades 17a and journaled in the casing 15. Dischargetubes 18 are connected to the casing 15 and extend down within a short distance of the track to be sanded. Feed-screws 19 are mounted in the tubes 1S and bear bevel-gears 20, having two sets of teeth 2la and 21b thereon. The teeth 21a are located to mesh with a bevelgear 22, carried by the shaft 4,while the teeth 21b are located to mesh with gears 23, keyed on the shafts 17 of the feeders. Spouts 24 are mounted on the lower ends of dischargetubes 1S.

In operation the box 1 is filled with sand of any description. When it is desired to sand the track,the crank 8 is operated to rotate the shaft 4. This action will Operate the discharge-blades l1 and cut-off arms 13 and force the sand through the apertures 9 in the bottom. This sand will run down into the chambers 16,when it will be engaged by blades 17 of the feeders and brought within reach of the screws 19,which will carry it down through the tubesI 18 to the lower ends thereof,where it will drop through the spouts 24 onto the track.

We do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of our invention.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a sander, the combination of a sandbox, having outlet-apertures in the bottom, a vertical shaft bearing discharge-blades set at an angle to the bottom thereof with their forward edges in contact therewith to adapt them to scrape the sand oif the bottom and raise it,and means for rotating Said slmftgsnb stantiftl'ly as desoribed.

2. In a sander, the combination of n sandbox,having discharge-aperto res in the bottom thereof, chambers located below said aperturesmoatable feeders mounted in said cimmbers,tubes connected to seid chambers, screws vmounted in said tubes, and means for driving said feeders and said screws, substantially is described.

3. In zt sander, the combination of a sandbox,havingdischarge-:upennres in the bottom thereof, e. shaft bearing discharge-blades lol i l eared to scrape the bottom of seid box, and eut-off arms carried by said Shaft and located beneath said bottom parallel to said dischargeb'mdes, substantially described.

In testimony whereof We have hereunto set our hands in presence of two Subscribing Witmesses.
