JAMES C. FINDLAY, 0F MARQUETTE, MICHIGAN.

ROAD-ROLLER.

To all whom it may concern:

Be it known that I, JAMns C. FINDLAY, a citizen of the United States, residing at Marquette, in the county of Marquette and State of Michigan, have invented certain new and useful Improvements in Road-Rollers, of which the following is a specification.

This invention has for its object to provide a snow or road roller in-which the roller or drum is in sections which are adjustable relative to each other so that a flat, convex or concave road-bed may be formed.

The invention also has for its object to provide a structure which prevents skidding or end slipping to the sides of the road.

A further object of the invention is to provide a novel construction and arrangement of parts to be hereinafter described and claimed.

In order that the invention may be better understood, reference is had to the accompanying drawings forming a part of this specification, in which drawings- Figure 1 is a plan view of the machine, partly broken away and in section. Fig. 2 is a side elevation thereof. Fig. 3 is a front end view partly in section.

Referring specifically to the drawings, the frame of the machine comprises longitudinal side bars 5 connected at their ends by cross bars 6, said bars being arranged to form a rectangular open frame in which the rollers or drums 7 are mounted. The side andcross bars may be ordinary L-beams as shown.

Three rollers 7 are provided which are arranged side by side and extend transversely of the machine. An independent axle 8 is provided for each roller but said axles are connected. The axle of the middle roller is mounted at its ends in fixed bearings 9 carried by bars 10 extending between and se cured to the cross-bars 6, and said axle is connected to the axles of the end rollers by knuckle or universal joints 11. The outer ends of the axles of the end rollers are supported in bearings carried by the side bars 5, said bearings having eccentric or take-up boxes 12 so that the said axles of the end rollers may be raised or lowered and thus thrown out of axial alinement with respect to the axle of the middle roller so as to extend at an angle thereto. This vertical ad-- Specification of Letters Patent.

Serial No. 669,736.

rollers are raised relative to the midde roller, a concave road-bed is made,and when lowered, the road-bed is made convex. Upon adjusting the axles of the end rollers so that all three rollers are in axial alinement, the road-bed is made fiat. Thev eccentric boxes 12 are provided with levers 13 for making the hereindescribed adjustments. The crossbars 6 carry arched beams 14 on which the drivers seat 15 and foot rests 16 are mounted.

A draft tongue 17 and other suitable devices for attaching the draft animals are provided, said draft attachment being mounted on either cross bars 6 -so that it may be reversed as shown by dotted lines in Fig. 2. The cross-bars 6 also carry scrapers 18 for removing mud, dirt, snow, etc., which may stick to the rollers 7.

In order to prevent the machine from skidding or slipping endwise to the sides of the road, the periphery of the middle roller 7 has an outstanding flange 19 at each end.

The machine herein described is simple in construction and highly etficient in operation, and it effectually serves the purpose for which it is designed, and by providing for the adjustment of the end rollers, the roadbed may be rolled flat, convex or concave as desired.

I claim:

1. A road-rolling machine, comprising a supporting frame, a jointed sectional axle comprising end sections and an intermediate section, the end sections of the axle being vertically adjustable and the intermediate section being fixed, and rollers carried by the respective axle sections.

2. A road-rolling machine comprising a supporting frame, a jointed sectional axle comprising end sections and an intermediate section, a fixed bearing for the intermediate axle section, vertically adjustable bear ings for the end sections of the axle, and rollers carried by the respective axle sections.

3. A road-rolling machine comprising a supporting frame, a jointed sectional axle comprising end sections and an intermediate section, the end sections of the axle being adjustable to extend in axial alinement with the intermediate section or at an angle thereto, and the intermediate axle section being fixed, and rollers carried by the respective axle sections.

4. A road-rolling machine, comprising a supporting frame, a jointed sectional axle comprising end sections and an intermediate section being fixed, and rollers carried by the respective axle sections, and a draft attachment connected to supporting frame and reversible thereon.
