UNITED STATES CHARLES GLEE, OF WHITE, NEBRASKA.

y ROAD DRAG.

Application filed October 26, 1923.

Y. '0 aZZ whom it may con-com:

Be it known that I, CHARLES Ginsu, a citizen of the United States, residing at lVhite in the State of Nebraska, have invented certain new and useful Improvements in Road Drags, of which the following is a specification.

This invention relates to improvements in road drags for scraping or leveling roads and highways and has for its object to provide a device of this character which can be adjusted to work at various depths, the adjusting means being yieldable to successfully withstand the strain incident to working or grading rough roads.

A. further and additional object of the invention is to provide a road scraper of simple and economic construction embodying comparatively but a small number of parts which can be readily and conveniently assembled into a working structure.

Various other objects and advantages of the invention will become apparent from the following disclosure wherein:

Figure 1 is a top plan view of the proposed scraper, 7

Figure 2 is a view in side elevation thereof.

Figure 3 is a sectional view along line 3-3 of Figure 1. and

Figure 4 is a detail section along line 4-4 of Figure 1.

The frame of the scraper is constructed of a pair of side beams 10 and 11 connected together at one end as indicated at 12, to provide a V-shaped frame as illustrated. Bean 1O constitutes the land-side of the frame and is provided with a land-side wheel 13 mounted on a shaft 14 suitably journaled in a boxing 15 at the rear end of the beam. The wheel is located on the inside of the beam which is provided with a substantially heavy strap iron 16 for supporting the in ner end of the shaft as illustrated. The opposite beam 11 of the frame constitutes the scraper side and is provided along its lower edge with a scraper blade 17. To beam 11 is also attached the draft rigging 18, the same being connected by a clevis 19 to a pull chain 20. One end of the chain being connected to a clamp 21 which is fastened about the beam as shown. The opposite end of the chain connects with a rod 22 which is likewise provided with a clamp 23, the latter being secured adjacent the rear end of beam 11.

The drivers seat 24 of the scraper is suit- Seria'l No. 670,920.

ably mounted on a platform of planking 25 extending between the supporting sills 26 and 27 which extend crosswise between beams 10 and 11 at a point preferably nearer the rear end of the machine than the forward end thereof.

In use the scraper is dragged over the surface of the road or highway to be leveled and the dirt thereof is scraped up and distributed by blade 17 and beam 11, the latter extending at an incline across the road as will be readily understood. The depth of the cut may be regulated from the drivers seat 24 thru the instrumentality of the lever 28. As shown in Figure 1, this lever is rigidly connected with one end of a crank shaft. 29 suitably journaled in

bearings

30 and 31, the former being located on beam 11 and the latter being mounted on a cross sill 32 extending between sills 26 and 27. The crank 33 of the shaft operates in a block 34 of a slot 35 carried at one end of a rocker arm 36. Arm 36 turns on a pivot pin 37 carried by the bracket 38 which is on sill 27. At its outer end arm 36 supports a ground engaging wheel 39 mounted to turn on a swivel 40 so as to readily follow the movement of the frame in any direction. lVhen crank 33 is turned to move theblock end of arm 36 upwardly, wheel 39 will be brought into engagement with the ground surface and will tend to lift beam 11 as the crank continues on its upward movement. Similarly, when the crank moves downwardly arm. 36 will be rocked on its pivot to elevate wheel 39, the weight of the frame causing blade to penetrate the surface of the road deeper and deeper as the outer end of the arm becomes elevated. The turning of the crank shaft is accomplished by means of lever 28 and in order that the same may be held stationaryin any position for locking the rocker arm, a brake ratchet 41 is loosely mounted on shaft 29 for engagement with the pawl 42 of the brake lever. On the inside of the brake ratchet and adjacent each end thereof is provided an outstanding lug 43. These lugs are adapted to alternately come to rest upon a flat arched spring 44 extending longitudinally of sill 32 to which it is secured as indicated at 45. This spring provides a} yielda-ble rest for the brake ratchet- When it is located on either the right or left side of the crank shaft and tends to absorb the shock imparted to the locked brake lever when the ground engaging wheel 39 engages ruts, rocks or other obstructions in a road. In the position of the'parts illustrated 1n Figure 3 it will be obvious that any upward movement of wheel 39 will cause block to impart a downward thrust on crank 33 of the shaft thereby tending to force the locked lever and ratchet in a downward direction. The downward; thrust ofthe lever and ratchet is yieldably resisted, in the present invention, by. springs 44 againstwhifch rests the ]ug;et3 of; the ratchet. Being elass tic,the spring; is flexed slightly under the; strain imparted thereto and, hence, serves;

to,- oushion the parts to prevent; break+ age or snapping off thereofunder, sudden or heavy strain and stresses. 7

From the foregoingit is thought that the adnantages and novelfeatures of the invention: can; be readily understood and; that;

further-detail description thereof is not required,

What. is claimed is:

1. A road drag comprising a scraper frame, a rocker-arm associated therewith, a.

ground engaging wheel atone end of thesaid arm, an operating crank engaging the ops poslte end of the arm forrockmg'the latter on its fulcrum, means for loeking the crank in ad usted. position and GUSlHOIHIlg-JDQQLDS for the said lock of" the: eran whereby the latter will be cushionedagainst the shock: impartedthereto.

2. A road drag: comprising; a scraper frame, a ground engaging wheel, arocker:
