SELF-STREWING SAN D-CARRIAG E.

SPECIFICATION forming part of Letters Patent No. 716,409, dated December 23, 1902.

Application filed July 31, 1902.

To all whont it may concern:

Beit known that we, CARL AUGUST GREEN, residing at Katrineholm, and HANS EDUARD LARSSON, residing at Stockholm, Sweden,

citizens of the Kingdom of Sweden, have invented certain new and useful Improvements in Self-Strewing Sand-Carriages; and we declare that the following is a full, clear, and exact description of the invention, which will IO enable others skilled in the art to which it appertains to make and use the same.

As above stated, this invention relates toa carriage for strewing sand on icy and slippery sidewalks, platforms, ways in parks,and

I 5 other frequented places, so as to avoid accidents caused by slipping; and the object of the invention is that the strewing of sand may be carried out easily, rapidly, and in uniform distribution.

The invention is characterized by a carriage provided with an arrangement adjustable during the operation for feeding out and regulating varying quantities of sand, which arrangement may be easily and in a convenient manner acted upon during the moving forward of the carriage.

The carriage and parts belonging to the same are shown on the annexed drawings.

Figure 1 shows a longitudinal section of the box or sand-tank, and Fig. 2 shows a similar section on a larger scale. Fig. 3 is a plan of the wire grate.

The sand-tank hopper a is at its bottom provided with one or more openings b for letting out the sand, the opening or openings being regulated by means of a slide, Fig. l, or a hinged door 0, Fig. 2, by the adjusting of which in different positions a desired quantity of sand may be let out. In order to facilitate the feeding, a rotating stirrer in the shape of a feeding-roll cl, with teeth, is arranged in the box a and over the opening or the openings. In order to distribute and spread the sand more easily, a perforated plate orawire grate 6 may be arranged obliquely beneath Serial No. 117,797- (We model.)

the outlet-opening, on which plate the sand strikes in falling before it reaches the ground. The grate e is pivoted to the box a, so that it will yield in moving the carriage forward by passing over obstacles, as stones or such like. The rear extreme position of the grate is, however, limited thereby that this latter is elongated beyond its fulcrum, which elongation lies against the box a. If slides are used, the adjustment may suitably take place by means of an angle-shaped arm f, Fig. 1, engaging with the slide or with arms 72, attached to the same, which arm may be in the shape of a bow, (see Fig. 1,) and by means of a lever g, adjustable in regard to its high position and acting on the slide. Besides, any suitable arrangement for the adjustment may be used, and the slide or door may also be adjusted directly by hand. In case of hinged doors the adjustment may take place there by that one or more arms 2, attached to the door, give the latter the desired high position by means of a lever k, adjustable in the same manner as the lever g. Such an arrangement for elfecting the adjustment may be taken the latter can be performed during the moving of the carriage forward thereby that the lever g or 70 is attainable for the person moving the carriage.

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

A device of the type set forth, consisting of a hopper, a feed-roll d therein, a perforated grate pivoted to the hopper and extending below the outlet thereof, a slide for closing the opening, a bell-crank connected to the slide, and a lever for actuating the bell-crank.

In testimony whereof we affix our signatures in presence of two witnesses.

CARL AUGUST GREEN. HANS EDUARD LARSSON.
