Specification of Letters Patent.

Patented J an. 36, 191'?.

To all whom it may concern,-

Be it known that we, GEORGE Gr. BAYNE and FRED A. RUNKLE, citizens of the United States, whose post-oiice addresses are respectively, Quincy, Adams county, Illinois, and lvl'acomb, McDonough county, Illinois, have jointly invented a new and usetul Road-Drag, of which the following is a specification.

Our invention relates to implements for dragging, smoothing, grading and surtacing roads; and the principal object of the invention is to generally simplify the construction and increase the utility and eiiiciency of devices of this character.

In the accompanying drawings: Figure 1 is a top plan of the Jform of drag preferred bv us; Fig. 2. a section in the line 2-2 in Fig. 1; and Fig. 3, a vertical, longitudinal section, taken in the line 3 3 in Fig. 1.

In the different views like parts are designated by the same reference characters.

4 designates the usual coupling-link and 5 a dratt-chain'the respective ends oi' which engage rings 6 which engage side tramebars 7 which are pivotally connected by deck-boards 8. The rear ends of the bars 7 are pivotally connected with brackets 30 which are fixed one to and near each outer end of the plane 11 and one at its midlength.

18 designates a cutting-plane and 2O denotes a bracket with which it is pivotally connected.

31 designates a knuckle provided with a vertically arranged aperture for the engagement of a king-pin 32, and with a horizontally arranged eye 33 in which the rockbar 20 is mounted.

34 indicates a rocker-casting having eyes 35 registering with the eye 33 and receiving the rod 20. To said casting 34 is suitably fixed the front blade or plane 18. Secured at 36n to the central frame bar 7 is a lever 36 the. fore end of which overlies the sector 39 and has an aperture adapted to register with any of a seri-es of openings 38 in said sector. 40 indicates a lock-pin. Connected at 41 to the head of the rockercasting 34 is the front end of a link 42 the rear end of which is pivotally connected by a pin 42 with a blade-rocking lever 48 which is fulcrumed in eyes 43 projecting from a. casting 50.

44, 44 designate brackets projecting from.

the casting 50 provided with corresponding slots 45 adapted for the passage of a lockpin 46 which is adapted for engagements with the series of openings 47 in said link. The plate is pivotally connected at its front end with the pin 32 and at its rear end riveted to the sector 39.

Fixed to the middle plate 8 are the ends of a Sector 51 provided with a series of openings 52 each of which is adapted for engagement by a pin 53 which passes first through the lever 36. The middle knuckle 30 hasan eye for the passage of a pivotbolt 54.

55 indicates a truss-plate the front end of which is pivotally connected with the pin 32 and the rear end similarly connected with the pin 54.

56 and 5? are retaining pins.

It will be noticed that the eye 4 may engage the links 5 either midlength of the chain or to one side thereof. as desired, to incline the drag members with reference to the direction of travel. The smoothing plane is stationary, and acts as a trowel or smoothing-plane. The front plane may be actuated by the lever 48 to rock it on its longitudinal axis whereby it may be made to stand vertically or inclined either forward or back.

The members 8, 11 and 18 are maintained constantly in parallelism. and this is true also of the members 7, 7', 7, 36 and 55. wWhile the sector 30 is concentric with, and the sector 51 eccentric to the center 32, the lever 36 is operatively connected with both of said sectors. The double-sector with which is operatively connected a single operating lever provides for extreme rigidity of the entire drag. Any desired lateral ad justment within limits may be made by withdrawing the pins 40 and 53 and moving the lever 36 laterally.

The curved contact-face 11 of the trowel or smoothing plane 11 Works especially well on moist or even muddy roads, for it acts as a trowel or smooth-er, gliding along and leaving a smooth, even surface. When working roads or grounds which are moist or wet, better results will be attained by inclining the lower edge of the blade or plane 18 rearward, so that it also acts as a drag, but when working very dry soils the blade 18 is preferably inclined in the opposite direction. It will be evident that the device is equally as well adapted for field as for road work.

Having thus described our invention we claim as new the following, to-Wit:

l. In a drag, a front plane, a rock-shaft on which it is mounted, a sector connected with the rock-shaft, a drag-frame pivotally connected at its front end to said plane, means for rocking said plane on said shaft, a plane at the rear end of the frame, a lever for swinging said frame in a horizontal arc relatively to the front plane, and means associated with said sector and lever for locking said frame from swinging.

2. In a drag, a front plane', a rock-shaft on which it is mounted, a sector connected with the rock-shaft, a drag-frame pivotally connected at its front end to said plane, means for rocking said plane on said shaft, a plane at the rear end of the frame, a sector iiXed on the frame, eccentric to the one recited, a lever adapted to swing the frame and rear plane in a horizontal arc, and plural means whereby said lever may be locked in engagement With both sectors.

3. In a drag, a knuckle, a rocker-casting pivoted thereto to rock in a vertical arc, a. plane fixed to said casting, a drag frame pivotally connected to said knuckle to swing in a horizontal plane, means for rocking said casting, means for locking 1t 1n set p0s1t1on,

which is attached to said casting, a leverl for moving said link forward or back, means for locking the lever in-set position, means for swinging the frame in the arc recited, means for locking it in set position, and a plane arranged at the rear part of the machine.

5. In a drag, a front plane, a rock-shaft on which it is mounted, a sector connected With the rock-shaft, a drag-frame pivotally connected at its front end to said plane, a. link for rocking said plane on said shaft,

a lever for imparting reciprocating movements to said link, a plane at the rear end of the frame, a lever for swinging said frame in a horizontal arc relatively to the front plane, and means associated with said sector and the last recited lever for locking said frame from swinging.

In witness whereof we hereunto set our Ahands this 1st day of April, 1916.

GEORGE G. BAYNE. FRED A. RUNKLE.
