SNOW-SCRAPER.

I Specification of Letters Patent.

Patented Oct. 20,1914.

` Application filed February 28, 1914. Serial No. 821,800.

to which it appertains to make and use thel same.

This invention relates to Scrapers, and

while especially adapted and intended fork scrapers to be employed for removing snow from ice for harvesting, it is not limited to such use or such purpose and is applicable to any form of scraper where it is desired to scrape and remove material surface. y

An object of the present invention is to provide a frame to which draft may be applied with wings pivoted thereto meeting at the rear in a V and with means for re leasing the wingsto permit them to assume substantially parallel positions to discharge the load and also to serve as runners for ytransportation of the scraper.

With these and other objects in view the invention comprises certain novel constructions, combinations and` arrangement of parts as willl be hereinafter more fully described and claimed.

In the drawings: Figure 1 is a top plan view of the improved scraper with the wings closed. Fig. 2 is a view of the scraper in end elevation as indicated by arrow 2 at Fig. 1. Fig. 3 is atop plan view of the scraper showing the wings open in parallel position for discharging the load and transportation. Fig. l isa sectional view taken longitudinally centrally through the device as indicated by line 1 -J1 of Fig. 3.

Like characters of reference designate corresponding parts throughout the several views. l

The improved scraper which forms the subject matter of this application comprises a frame which may be of any approved or desired form or construction, here shown as comprising a cross beam 10 substantially straight, and a curved beam 11 connected with the beam 10 at its opposite ends and spaced centrally therefrom by parallel-bars 12. yThese beams are preferably of angle iron as shown, and their lower edges stand in a single horizontal plane.

from a given Apole 13,701' any approved form'of attaching draftjto the frame is provided so that the frame-,may be moved over the surface which itis Adesired to clean. V

Atits opposite ends theframe 'composed of the members '10 and 11 is provided with downwardly extending pintles 14: upon which the front ends y"of'wings 15 are pivoted in any approved manner as by employing a bracket-p16 secured to. the exterior of each of said wingsand having eyes throughwhich the pintles 14 extend. Each wing stands upright beneath the framework andv is lirmly supported on the pivot at its front end, its' upper edge passing under and in contact with the beams 10 and 1l above, whatever the position of the wing, and by this1 means lthe framework is supported on the wings. lt will be noted that the wings 15 are so proportioned that when they are brought together with their rear ends contacting as shown at Figs. 1 and 2 they form a Vfshaped body under the frame.` To maintainthe wingsin such relation flexible members 'as the chains 17 are employed secured to the wings in'any approved manner as by employing a strengthening rib 1S and eyeybolts 19 with the chains passing over a roller 20 at the front of the frame and rearwardly to a winding drum 21 mounted on the rear of the frame. The winding'drum is provided at one end with a` ratchet 22 as shown particularly at Fig. 3 with a detent 23 which is carried byv a lever 24 standing adjacent a seat 25 upon which the driver is supposed to ride. y y

Vith the device assembled as shown at Figs. 1 and 2 it is driven across the ice or other surface to be. cleaned until the wings 15 are loadedqwith snow or othermaterialy and is then driven off to some location where the load may be dumped without detriment.

Arrived at such location lthe lever`24 ,is liftedwhich releases the winding drum 21 and permits the wings 15 vvto swing out' wardly to `parallel position as shown at Fig.

3, such' .swinging being facilitated by the load andthe position is such that the wings are then vmoved with the frame leaving the loadwhere it isdumped and also serving as runners for the device while being returned to position for another load. `When arrived at the position where the cleaning is to be continued the wings are returned to the position shown aty Fig. l, the chain wound about the winding drum and retained by the detent Q3 when the device is again ready to perform its operation as above described.

I claim:

In a scraper, the combination with a framework comprising a straight cross beam and acurved beam rear of and connected at its ends with said straight beam, the lower edges of the beams standing in a singlo horizontal plane, means for applying draft to said framework, and aroller and; winding drum mounted on such framework; 1 0f pntles depending rigidly from oppositeE .ends of the framework, two wings stand` ing on edge beneath the framework, ,ai`

-a chain connected with the rear end of the wing and passing over said roller to the winding drum.

In testimony whereof afX my signature .in presence of witnesses.
