ROAD-DRAG.

No. 924,31 1. Specification of Letters Patent. Patented June 8,1909. Application filed January 7, 1909. Serial No. 471,196.

To all whom it may concern: the drawings. The T-bar 6 has its base Be it known that I, DAVID C. BOYD, citizen flanges 7 cut away at the ends to form end of the United States, residing at Galion, in recesses 8, the vertical flange being left to the county of Crawford and State of Ohio, constitute end tongues to which the vertihave invented certain new and useful Imcally extending ortions of the actuating provements in Road-Drags, of which the folarms 9 are pivotal y connected, the said arms lowing is a specification. eing arranged in two pairs front and rear,

is invention comprehends certain new and the arms of the respective pairs embracand useful improvements in road scrapers or ing the tongue as shown. The horizontally leveling devices, and the invention has forits extending portions of the arms 9 roject in object an improved construction of devices opposite directions and are bolted orothen of this character, embodying pivoted blades wise secured to the angle bars 3 near the midthat may be tilted to different inclinations, dle part of the latter. The upper ends of the as well as a novel and efficient mechanism for front and rear airs of arms 9 are connected tilting the blades and for holding the same at together by a l ongitudinally extending bar the desired inclined positions. 10. A rack 11 is secured in any desired way With this and other objects in view, as will to the side of the connecting bar 10, and a more fully appear as the description prospur pinion 12 meshes with said rack. The ceeds, the invention consists in certain conpinion 12 is secured to a vertically disposed structions, arrangements, and combinations operating rod 13 which is provided at its upof the parts that I shall hereinafter fully per end with a hand wheel or other device by describe and claim. which it may be easily turned, and which is For a full understanding of the invention, ournaled intermediate of its ends in a shaft reference is to be had to the following desupporting bar 15. This shaft supporting scription and accompanying drawings in bar 15 is secured at its ends to approxiwhich: mately U-shaped brackets 16, supported by Figure 1 is a perspective view of my imand secured to the platform or framework of proved road drag or eveling device: Fig. 2 is the device. a top plan view thereof: the actuating shaft 17 designates the platform of the device, or rod thereof being shown in section Fig. 3 the platform being made preferably in two is a longitudinal sectional view on the line sections at opposite sides of the single interof Fig. 2; and, Fig. 4 is a detail perspecmediate beam 6, and being formed of any tive view of the intermediate beam of the desired material or any desired construction framework. or design, and the lower end of the o erating Corresponding and like parts are referred rod 13 may be journaled in one of tie platto in the following description and indicated form sections or on one of the base flanges of the T-bar 6.

in all the views of the accompanying draw- From the foregoing description, in connecings by the same reference characters.

In the present embodiment of the invention with the accompanying drawings, it is manifest that the b ades 1 and 2 may be tion, my improved road leveler or drag comtilted to any desired inclination by turning prises a forward blade 1 and a rear blade 2, V the same being bolted or otherwise secured to the operating rod 13, which through the instrumentality of the pinion 12 and rack 11 the front sides of transversely extending I T-bars 3. A plurality of angular brackets 4 will move the connecting bar 10 in one direction or the other to actuate the arms 9 and are bolted or otherwise secured to the horizontally extending flanges of the T-bars 3, tilt the blades.

In order to hold the blades either vertical one pair of brackets for each bar, and the vertlcally extending portions of said angle or in any desired inclination, the operating rod 13 carries at its lower end a detent wheel 1 brackets are pivotally connected by bolts or 18, and a detent or pawl 19 is pivotally similar fastenin devices to the longitudinally extending beams 5 of the framework of mounted upon one side of the vert cally extending flange of theT-bar 6, said detent being said apparatus. The said framework embodies, in addition to the lon itudinally exprovided with an angularly disposed nose 20 designed to dro into any of t 1e notches of tending end beams 5, a single ongitudinally extending intermediate beam 6 which is in the detent whee 18,1t bemg understood that the form of aT-bar, as clearly illustrated in the forward engaging end of the pawl 19 overbalances the rear end so as to avoid the necessity of using s rings. The rear end of the detent is latera ly extended as indicated at 21 and is somewhat broadened to form a foot treadle, so that the operator may readily depress the rear end of the detent and disengage the front thereof from the detent wheel 18.

The draft chains 2 or similar devices for drawing my road leveler over the roads may be secured to the framework of the device in any desired way.

Having thus described the invention, what is claimed as new is: I

1. A road drag, comprising a supporting framework, embodying a plurality of longitudinally extending beams, blades having pivotal connectionbetween said beams, actuating arms connected to said blades and fulcrumed intermediate of their ends to one of the beams, a connecting bar pivotally secured to said actuating arms above the fulcrum points thereof, a rack carried by said connecting bar, a pinion meshing with said rack, and a vertically extending rod journaled on the framework, the pinion being carried by said rod.

2. A road drag, comprising a plurality of blades, a plurality of longitudinally extending beams, to the end ones of which said blades are pivotally connected, actuating arms connected to said blades, and fulcrumed intermediate of their ends to the intermediate beam, a connecting bar pivotally connected to the actuating arms above the fulcrum points thereof, a rack bar carried by the connecting bar, a vertically CllSliOSGCl operatlng rod, a supporting bar in w nch said l l 1 l l operating rod is journaled, and a pinion carried by said operating rod and meshing with said rack bar.

3. A road drag, comprising a supporting framework, blades pivotally connected to said framework, said framework embodying end beams, a single intermediate beam consisting of a T-bar, said T-bar having its base flanges cut away at the ends whereby to form end tongues, actuating arms operatively connected to the blades arranged in front and rear pairs embracing and pivotally connected to said end tongues, means connecting together the front and rear actuating arms at the upper ends thereof, and m ans for swinging said arms whereby to tilt the blades.

i. A road drag, comprising a supporting framework, blades pivotally connected to W said framework, actuating arms fulcrumed on said framework, operatively connected to said blades, a connecting bar secured to the actuating arms, a rack carried by said connecting bar, a vertically disposed operating rod journaled on the framework, a pinion secured to said red and meshing with said rack bar, a detent wheel secured to said rod and meshing with said rack bar and formed with notches, and a detent pivoted on the fran'rework and formed at one end with a nose to engage the detent wheel, said detenr being formed at its other end wit h a treadle. in testimony whereof l allix my signature in presence of two witnesses.
