Application filed March 23, 1927. Serial No. 177,618.

This invention relates to improvements in scrapers and more particularly to snow or dirt scrapers of a manually operable type. One object is to provide a snow scraper that is of simple construct-ion, cheap to manufacture and that positive and efficient in operation.

With the hnegoing and other objects in view the invention consists in the combina tion and arrangement of parts to be hereinafter fully described, particularly pointed out in the appended claims and illustrated in the accompanying drawing which forms a part of this application and in which" Fig. 1 is a top plan view of the scraper, a portion of the handle being broken away.

Fig. 2 is a View of Fig. 1 in rear elevation.

Fig. 3 is a vertical sectional view through the scraper.

Like reference characters denote corresponding part throughout the several views.

The present invention is designed primarily for the purpose of removing snow from side walks, driveways, verandas and the like or for use in the summer time to gather refuse, street dirt and the like and dispose it in piles ready for removal. It is manually operated and is designed to accomplish the maximum amount of work with the minimum labor.

The scraper comprises a back or body portion to the ends of which a pair of wings are hinged, said wings being so connected to each other that they are always disposed at right angles to each other and move simultaneously.

The scraper comprises the body portion 1. curved forward slightly along its lower edge 1 and to the ends of which portion the wings 9., 3 are connected by hinges 4. Lugs 5 are secured to the ends of the body 1 and extend therebeyond for bracing engagement with the wings in one position of the same. To the wings 2, 3 the links 6 are made fast and to the same the bars 7. two in number. are pivotally connected. The said links 6 extend outwardly or away from the hinges 4 and the arms 7 are connected to the free ends of said links and connect the same pivotally to the handle 8, the pivot bolt 9 serving to connect the inner ends of said bars 7 and the handle. The bars 7 in connecting said links and handle pass between the hinges 4 and over the top of the body portion 1 of the scraper. The wings are so connected to each other by the links, bars and handle that the wings are always disposed at right angles to each other.

The rotary handle 8 is a curved or bent rod opcratively connected by the keepers l0, 11 to the body portion 1 of the scraper upon the same side thereof as the hinges, a cotter pin 12 serving to prevent withdrawal of said handle from its keepers. A segment 13 having its ends secured to the top edge of the back or body 1 extends rearwardly and up ward slightly therefrom and is adapted for engagement, through the medium of any one of its three peripheral notches, with the latch 14 fulcrumed upon the handle 8 and connected by a contractile spring 15 to the said body 1, said spring serving to yieldingly retain the latch and segment in'engagement with each other.

By manually raising the latch out of engagement with the segment and rotating the handle 8 the wings 2, 3 will be moved simultaneously relative to the body 1 and when the latch is again dropped into operative engagement with the segment the wings will be locked in their then adjusted position. For

scraping snow the adjustment of the wings is preferably as shown in Fig. 1, the wing 2 in line with the body 1 and the wing 3 at right angles thereto, or the wingsmay be 50 adjusted that both form obtuse angles with the body portion.

\Vhat is claimed is 1. In a scraper, a body portion, end wings adjustably connected thereto, and manually operable means secured to said body portion for actuating said end wings simultaneously 2. In a scraper, a body portion, end wings adjustably connected thereto; and manually operable means secured to said body portion for actuating said end wings simultaneously, said means retaining said end wings constantly at right angles to each other.

3. In a scraper, a body portion, end wings hinged thereto, links secured to said end wings, a rotary handle secured to said body portion, arms operatively connecting said links and said rotary handle, and means connecting said handle and body portion for releasably locking said handle in adjusted positions relative to said body.

4. In a scraper, a body portion, end wings hinged thereto, links secured to said end wings, a rotary handle secured to said body portion, arms operatively connecting said links and rotary handle and passing across said body portion between the hinges of said end Wings, and means connecting said body portion and handle for releasably locking the latter in adjusted position relative to said body.

In a scraper, a body portion, end Wings hinged thereto, links secured to said end Wings, a rotary handle secured to said body portion, arms operatively connecting said links and said rotary handle, a segment car-- ried by said body portion, a latch irulcrurned to said handle for engagement- With said segment, and a spring connecting said latch and body portion.

In testimony that I claim the foregoing as my own I hare hereto atiixei'l my signature.

CHARLES LARSON.
