BEAUMAN BUTLER, OF ST. JOHNSBURY CENTRE VERMONT, ASSIGNOR OF ONE-HALF TO CORTES T. BRIGHAMS, OF SAME PLACE.

STREET-SANDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 337,300, dated March 2, 1886.

Application filed July 23, 1885. Serial No. 172,453.

To all whom 216 may concern Be it known that I, BEAUMAN BUTLER, a citizen of the United States of America, residing at St. Johnsbury Centre, in the county of Caledonia and State of Vermont, have invented certain new and useful Improvements in Street-Sanding Machines; 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention has reference to machines for sanding pavements, sidewalks,&c.; and it consists in theimprovementshereinafter described and explained, and then sought to be defined by the claim.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of the sanding-machine embodying my improvement. Fig. 2 is a front elevation of said machine, a part or portion thereof being represented in sections. Fig. 3 is a side elevation of said machine, also partly in section; and Fig. 4 is a detail perspective view of one of the castings forming in part the deliveryspouts or discharge-openings.

Upon any suitable frame work composed of bars A is mounted a receptacle, B, the bottom of which is formed to present two converging troughs or hoppers, O G, the front trough, O, of which is of somewhat larger dimensions or o 5 capacity than the rear trough, O. The bottom of each trough is provided with a series of smaller plates, a a, which converge or incline toward openings 12 I), located in the bottom of said trough.

By reference to Fig. 1 it will be observed that the receptacle B is extended sidewise or transversely at its lower portion, in order that the transverse width of the trough O at its lower portion will be greater than that of the 5 trough O at its base or lower portion. It will be noted that the additions or extensions of the front trough make provision for two additional discharge or delivery openings, b.

ends of a short transverse horizontal shaft,

D, upon which are rigidly secured the upper ends of two depending arms, e, the freeend of each of which is located in front of and immediately opposite the two central openings, 1) b,

of the front trough, O. The lower or free end of each arm e is provided with an eye or opening for the. pivotal connection of the loop e, secured to the front end of a horizontal slide 6 or cut-off, E, which plays in guides e beneath one of the openings 1), to control the passage of the sand through the same. Of course, it will be comprehended that the said slide or cut-off is perforated, and it may properly operate for 6 the purpose intended. A horizontal beam, F,

is rigidly secured transversely beneath the front hopper, O, by means of brackets f, (see Fig. 3,) and the position of said transverse beam, as illustrated in said figure, is slightly at one side of the discharge-opening b of said hopper. The said beam has located therein the rear ends of two bolts, f, which extend horizontally toward the front of the machine beneath the hopper. A second beam, G, similar to the beam F, is located parallel therewith and at some distance in advance of the same, but is supported in position by being pierced by the boltsf, the ends of which project beyond the front face of the said beam G, for the engagement of thumb-nuts g, by means of which the last-mentioned beam is adjusted to and from the beam F.

By reference to Fig. 3 it will be observed that the beam G is located slightly to one side of the opening I; of the front trough.

The beams F G are provided on their adjacent faces with a series of metallic castings, H H, which are rigidly secured in position, and are each of a shape approximating that of a triangle. Each of said plates H H is provided with a vertical web or body, h, having perforations h for the passage of the bolts or other securing devices by which it is attached to its beam. Each of said plates H H is further provided on its converging upper edges with a curved flange, h. It will be noted that the plates H H are located in line with and immediately opposite each other, so that their respective curved flanges h extend toward rco each other, and thus tend to conjointly present inclined delivery grooves or channels, the

apex of which is located immediately below one of the discharge-openings b of the trough (l. A vertical lever, I, is fulcrumed upon the front of the machine, and has its lower end connected by a link, i, to one of the depending arms e, in order that the cut-offs E of the two central openings may be simultaneously operated thereby.

The two openings 6 b are provided with operating devices, cut-offs, beams, and adjustable delivery-plates, similar to the arrangement and devices described with reference to the front trough, 0. It will therefore be sufficient to state that one of the arms e of the rear trough is connected by a rod, j, to one end of a lever, M, and thus insures the independent operation and movement of the cut-oil slides E of the central opening. b, and the openings b. The outer openings 11 are provided with cut-off slides E, which are operated by independent levers J J.

In operation the several levers are moved so that the slides of the several openings permit the sand to pass through the same onto the apex of the series of the companion plates H Hbelow. The sand then further continues down the inclined grooves or channels presented by the eurvedflanges of said plates and gradually and regularly sifts through the opening between said flanges and spreads evenly on the ground. The relative adjustment of each of the beams G will control the distance between the fianges of the plates H H, and consequently the amount of sand fed or delivered between the same.

By having the slides of the outer openings b operated byindependent levers the delivery of sand from the extended portions of the front hopper may be suspended irrespective of the central opening. It will therefore be apparent that the outer openings can be utilized to deliver the sand close to walls, in corners, or other places inaccessible to the central openings, b b, and rear openings, 1) b, in line therewith.

The construction and operation of the beams F G and plates H H insure the delivery of the sand in a thin spray or sheet, and additionally enable the employment of substances other than sand, as, for instance, pulverized ashes, &c.

While in the drawings I have represented the machine as being provided with shafts K K and side carrying-wheels, L L, to adapt the machine for use in connection with a horse or horses, still it will be desirable in some instances to use only a pivoted draft bail or tongue to enable the machine to be drawn along by hand. In case of the employment of said bail or tongue, as noted, the latter will be provided with a wheel and side chains to brace the same and divide the strain.

I claim- The combinat-ion, in a sanding-machine, of a suit-able trough or receptacle provided with openings in its bottom, and plates H H, having triangular ribs, conjointly forming broadcast-channels, one of said plates being adjustable relative to the other, hand devices for adjusting said plates, and cut-off devices for 0011- trolling the feed through the openings, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

BEAUMAN BUTLER. Witnesses:

P. L. PIERCE, L. V. MENUT.
