Filed May 5, 1932 ik? L, 202g Patented May 30, 1933 UNITED STATES IRA. L. LONG, OF PEORIA,` ILLINOIS f SCRAPER i Appiieation med may 5, i932.l serial No. 609,366.

My invention relates more particularly to Scrapers intended for use on tractors which are provided with a pair of front wheels mounted so that their treads closely approach one another at the point of contact with the ground and diverge upwardly.A

These wheels are usually each provided with a flange located at the adjacent edges of their rims and it is found that when this type of tractor is used in muddy and trashy soil, the wheels have a tendency to pick up and accumulate the soil and trash and eventually the amount of this material which is collected and which accumulates around the central vertical steering head seriously interferes with the operation of the tractor and it becomes necessary to stop frequently and remove the accumulation and so it is an object of my invention to constantly trim the outer preventing any accumulation of` earth or trash between the wheels.

It is found that if the adjacent outer edges N of the flanges are trimmed, any accumulation of earth, stalks, or trash, on the tread of the wheel will slough olf in a subsequent revolution of the wheels and will not result in clogging any of the mechanism.

The novelty of my invention will be hereinafter more fully set forth and specifically pointed out in the claims. y

In the accompanying drawing:

Fig. l is a plan view of a pair of typical tractor front wheels showing my scraper '3 mounted and in operative position, the parts being shown in proper relation, the front of the tractor, or its direction of movement being toward the left.

Fig. 2 is an enlarged plan view of the scraper shown in Fig. l.

Fig. 3 is a side view of Fig. 2.

The same numerals of reference are used to indicate identical parts in all the figures.

As showing one form of device embodying D my invention, though without limiting myself to the details of construction and arrangement of parts shown and to be herein described, but availing myself of all changes and modifications that may be made within the scope of the appended claims, I have edges of the flanges of the wheels, therebyy shown a Vscraper consisting of a body portion 4, a pair of divergent scraper blades 5, a' pair of attaching pins 6" and 7, and a pair ofjeXvpansion springs 8 mounted on'the pin 7 and between'the body 4 and blades 5, to urge the 55 blades away from each other andl against the flanges 9 ofther wheels 1(7).` The body portion f4 is .preferably formed of'` apiece of channel section material and it ispreferably attached under the steering head by means of 69 a'bolt passing through the hole 1l and into the under portion Vof the steering head. The mounting of the bodyportion 4 should permit it to swing sidewise so that it lindsits own center betweenV the blades l5 when the 65 latter come in contact with theedges of the' wheels totheend thatthe maximum lateral motion of either'blade 5 Vmay be the total compression of both Vsprings 8, a furtheradvantage being that through this arrangement, 70 the pressure on eachV blade 5 against its wheel will be the ysame, as that of the other. ,An other result Vof this arrangement is that should one of the springs 8 break, theother will cause the body portion 4 to swing and so 75 both scraper blades will be maintained in contact with their respective wheels.

The holes in the parts through which the pins 6' and 7 pass are mad-e sufficiently large to permit these parts to perform their various movements.

The lower or cutting edge of the blades 5 are preferably formed somewhat after the manner of a sled runner to the end that their contact with the wheels will produce a shearing action to either cut the trash or earth from the flange of the wheel or dislodge it by forcing it away from the wheel.

As better shown in Fig. 2, the blades 5 are 90 slightly twisted away from each other at their lower free edges thereby presenting a better cutting edge at the point of contact with the wheel flanges.

It will be seen -from the above that I have 9.5 produced a scraper of few and simple parts which are cheap to produce, easy to assemble, and which when mounted upon the tractor, efficiently perform the functions for which they are intended.

Having thus fully described my invention, I claim:

1. In a scraper the combination of a body7 portion, a pair of blades moyably mounted thereon and each adapted to Contact with a wheel, and a spring (3o-operating between each blade and the body portion to urge the blades apart at their free ends and into contact with a wheel.

2. In a scraper the combination of a swingable body portion, a pair of movable blades mounted thereon, and a spring cooperating between the body portion and each blade to urge the blades into Contact with the wheel, each blade forming' the abutment for the pressure applied to the other.

8.' In a scraper the combination of a body portion, a pair of pins carried thereby, a

i pair of blades each engaging both pins, and

a pair of springs mounted between each blade and the body portion upon one of the pins whereby to urge the blades apart at their free ends and into Contact with a wheel.

4. In va scraper the combination of a laterallyswingable body portion, a pair of pins carried thereby, a. pair of blades each engaging both pins, and a pair of springs mounted between each blade and the body portion upon one of the pins Vwhereby to urge the blades apart at their free ends and into Contact with a wheel.

5. In a scraper the combination of a swingableI body port-ion, a pair of blades movably mounted thereon and each a-dapted to Contact witha wheel, and a spring oooperating' between each bladeand the body portion to urge the blades apart at their free ends and into Contact with a wheel.
