GAGE-WHEEL FOR SCARIFYING DEVICES.

Specification of Letters Patent. Patented Aug; 23, 1921.

Application filed September 13, 1920. Serial No. 410,069.

To aZZ whom it may concern Be it known that I, HENRY D. JoNEs, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio,-have invented certain new and useful Improvements in Gage-Wheels for Scarifying Devices, of which the following is a specification.

This invention relates to improvements in scarifying devices of the kind which are attached to the rear end of road engines, it relating more particularly to a novel construction of gage wheel for use in connection with such devices.

One of the objects of my invention is to provide a gage wheel so constructed and associated with the scarifying tools as to prevent clogging of the road material, earth or trash between the wheel and the adjacent tool.

A further object of my invention is to provide a gage wheel sov constructed as to obviate side strain upon the parts.

In the accompanying drawings Figure 1 is a rear view of so much of a road engine and the scarifying devices as is necessary to illustrate the invention, showing my improved gage wheel applied thereto.

Fig. 2 is a vertical section of one of the gage wheels.

The scarifying devices which I have shown are constructed substantially like the scarifier illustrated in my prior Patent No. 1,226,528 dated May 15, 1917. The scarifier devices are attached to the rear end of the tank 1 of the engine by providing a frame consist ing of the upright supporting members 2 and 3 bolted or otherwise firmly secured to the tank. The lower end of this frame has bearings i in which is journaled a draft bar 5 to which are keyed a series of tool holders 6, to the rear free end of which are clamped the ground breaking tools 7. Connected with each of the tool holders 6, at points adjacent the rear end thereof is a shaft 8 which projects laterally beyond the series of tools at each side of the machine and has jourlnaled thereon gage wheels 9. A fluid pressure cylinder 10 has its upper end pivoted on a shaft 11 supported by the upper end of the frame members 2 and 3 and the piston rod 12 of the piston of this cylinder is connected to a yoke-shaped member 13 journaled on the shaft 8 so that the scarifying devices may be raised and lowered and pressure applled thereto 1n the manner described 1n my prior patent referred to.

In the use of such devices, difficulty has been encountered with trash, such as the hard surface of roads, lumpy earth, or other substances encountered, accumulating between the gage wheel and the adjacent tool when the gage wheel is constructed in the usual and ordinary manner such as shown in my prior patent referred to. Further, these gage wheels as heretofore constructed are the cause of considerable side strain upon the parts, particularly when the machine is making turns or being moved diagonally across the road, which has resulted in straining the tank to such an extent as to cause it to leak as well as bringing undesirable strain upon the operating parts. To obviate these difliculties I have c011- structed each of the gage wheels as follows The hub 14; of the wheel is connected to the inside edge of the tread 15 thereof by a web portion 16. This web portion 16 con nccts with the hub at a point adjacent its inner end and projects inwardly toward the center of the wheel so that the outer portion thereof will connect with the tread 15 at a point which will be substantially on a line with. the center of the hub so that the web projects at an angle outwardly away from the adjacent scarifying tool so as to form in effect with the tool an outwardlv flaring throat. As a result of this construction the trash which is encountered between either one of the gage wheels and its adjacent tool will he allowed to escape freely from be tween the same, being assisted in this 1: .spect by the rotation of the gage wheel.

The respective edges of the tread portion 15 of each gage wheel are formed on the arc of a circle or rounded, as indicated at 15 and 15, as a result of which the wheels are permitted to more readily ride out of ruts and depressions encountered and thus obviateto a large extent side strain upon the parts.

The hub, tread, and web are all preferably formed integrally and a series of webs 17 are preferably provided for strengthening purposes.

Having thus described my invention, I claim 1. In a scarifying apparatus, a series of scarifying tools, gage wheels associated therewith, theside of each wheel being inclined outwardly away from its. adjacent tool, for the purpose specified.

2. In ascarifying apparatus, a series of pivotallysupported tools, gage wheels connected with said tools, one at each end of the series thereof, each gage wheel being provided with a web portion which is inclined outwardly away from its adjacent tool, for the purpose specified.

3. In a scarifying apparatus, a scarifying tool, a gage'wheel adjacent thereto, said gage wheel having a hub and a tread portion, a web connecting the same, said web being connected with said hub at a point adjacent its inner end and extended out- HENRY D. JONES.
