SCRAPEB.

VApplication led August 31, 1926. Serial No. 132,759.

This invention relates to scrapers and is designed more especially as an improvement upon the structure disclosed in Patent No. 1,559,9d6 issued to me on November 3rd, 1925.

It is an object of the invention to render the structure more substantial, more efficient in operation, and better adapted for quantity production.

lVith the foregoing and other objects in` view which will appear' as the description prevede, the invention resides in the conibination and arrangen'ient of parts and in the details ot construction hereinafter described and claimed, it being understood that changes inl the precise embodiment of the invention herein disclosed may be made within the scope ot what is claimed, without departing from the spirit of the invention.

ln the accompanying drawings the preferred torni ot the invention has been shown.

1n said drawings,

Figure l. is a plan view of the scraper.

Figure 2 is a longitudinal section.

Figure 8 is a section on line 3 3, Figure 2.

Referring to the iigures by charactersof rete-rence 1 designates a handle of any desired length on one end ot which is iitted a ferrule 2 having its free end portion flattened out and broadened 'to provide a head 3 having depending side ears l. The blade of the scraper has been indicated at 5 and is formed of asheet ot suitable metal having its longitudinal edge portions bent to provide a scraping portion 6 and a reinforcing portion 7. Fastened on the 4t and 9 andis held in place by a nut 11 or the like. Mounted on that portion ot the bolt between the ears 4 is a coiled spring 12 one end of which bears against the inner surface of .the ferrule as shown particularly at 13 while the other end bears against the blade 5 as shown at 14.

It will be apparent from the foregoing description that under normal conditions the spring by exerting a constant pressure against the blade 5, causes the upper portion of the blade to thrust against the end of the head 3 so that the blade will thereby be held normally in the position shown in Figure 2. Consequently when the scraper is drawn toward the operator there is no danger of the same collapsing. However when the strip is thrust away from the operator the blade will ride over the surface of the ground and any material accumulated thereon and will be free to swing to the dotted position shown in Figure 2 against the action of the spring 12. As soon as the scraperis lifted out of contact with the ground, however, the spring will return the blade to its normal positions.

Vhat is claimed is:

A scraper including a handle engaging ferrule having a broad flat end portion, downturned ears integral with the sides oi' said end portion, a sheet metal blade having both longitudinal edges curved to reinforce the blade longitudinally, a plate secured to and extending longitudinally of theI blade having spaced ears struck therefrom for receiving between them the ears on the end portion of the fer rule, a pivot bolt extending through all of the. ears, and a spring mounted on the bolt and housed between the ears, one end ot the spring engaging the end portion ot the :terrule an the other end engaging the plate, thereby to hold the blade normally pressed against the free end of the Hat portion of the ferrule at a point between the curved portions of the blade.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

OSCAR FANBERG.
