ROAD-EN'GIN E.

SPECIFICATION forming part of Letters Patent No. 498,918, dated June 6, 1893. Application filed April 8, 1893. Serial No. 469.509. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM CHURCHILL OASTLER, of the city and county of New York, in the State of New York, have invented a new and useful Improvement in Road-Engines, of which the following isa specification.

This invention is especially applicable to what are known as steam road rollers but is applicable generally to road engines which, like steam road rollers, are sometimes required to be used for plowing.

One object of the invention is to obtain a more direct draft of the roller or engineupon a plow while the latteris used for plowing up the sides of a road or in lines at or near the sides of the track of the roller or engine.

Another object is to afford convenience for carrying a plow on the roller or engine when plowing is not required to be performed The drawings represent my invention as applied to a steam road roller but only represent in detail those parts to which the improvement particularly relates.

Figure 1 is a horizontal sectional view of the roller. Fig. 2 is a rear view on a larger scale than Fig. 1, of the tender, the driving wheels and the devices for attaching and drawing the plow. Fig. 3 is a side view corresponding with Fig. 2.

Similar letters of reference designate corresponding parts in all the figures.

A is the boiler, the fire box B of which has its outer sides prolonged in a rearward direction as shown at a a in the form of what are known as horn plates between which is arranged the engineers platform b and in the rear of which is arranged the tender 0 the side walls of which areprolonged in a forward direction as shown at c c and bolted to the horn plates at a as shown at d d in Figs. 1 and 3, the horn plates and the tender thus constituting parts of the framing of the roller or engine.

D D are the driving wheels arranged on opposite sides of the tire box, platform and tender.

The parts thus far referred to are like those of steam road rollers in common use and are only described for the purpose of explaining my invention.

E E are strong side plates or bars of steel or iron bolted as shown at e e and d d in Figs.

1 and 3, to the exterior of the tender and horn plates, one on each side, and extended a little beyond the rear of the tender, the so extended parts being slotted to receive a transverse horizontal bar F which passes through the said slots and is secured lengthwise by keys ffinserted through it outside of the bars E E. The said bar F is long enough to project laterally in contrary directions beyond the centers of the width of the driving wheels to permit the attachment to it, opposite each of said wheels, of a shackle g to which to attach the plow, provision being thus made for a direct draft on a plow for plowing up the sides of a road or the parts thereof at the sides of the track of the road roller or engine, this direct draft obviating the tendency to turn the roller or engine which results when a plow connected by a central shackle h, as is common, is directed toward the sides of the road or track.

To give proper stifiness to the bar F to resist the draft on the shackles g g, so far from its supporting side bars E E, diagonal braces G G are applied between the said side bars and the outer portions of the said bar F.

To provide for carrying the plow at the rear of the road roller or engine when not in use, two bracketsl I are provided each consisting of an upwardly bent arm having at one end a shank or stem 2' which will drop into and fit one of two holes provided in the bar F, the said shank or stem being of square or such other form that the said shanks or stems will not turn in the said holes. When the plow is to be carried the brackets have their stems so inserted in the holes that their arms stand out directly rearward as shown in full outline in Fig. 1 so that the plow may rest and be carried upon them. When the plow is in use the brackets may be removed from the bar F and replaced therein with their arms in reversed posit-ions as shown in dotted outline in Fig. 1 where they will be out of the way.

It is obvious that the bar F prolonged to the extent described for the attachment of the shackles g, might have its prolongation produced by adding extension pieces to the shorter bar commonly employed in the place occupied by the said bar F, extending only just a little way through the side plates E, and

bolting or riveting the said extension pieces to the said shorter bar.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination with the side framing and driving Wheels of a road engine or steam road roller, of side bars E E attached to the said framing, a transverse bar F inserted through the said side bars and projecting beyond said side bars opposite each or either driving Wheel and means for attaching a plow to said transverse bar opposite the driving wheel, substantially as herein set forth.

2. The combination with the side framing of a road engine or steam road roller, the side bars E E attached to said framing and the transverse bar F inserted through and projecting outwardly beyond said side bars, and diagonal braces G G connecting the so projecting parts of the said transverse bar with said side bars, substantially as herein set forth.

3. The combination with a road engine or steam road roller and a transverse bar attached to the rear thereof for drawing a plow, of brackets inserted in said transverse bar and movable therein to and from positions for carrying the plow when not in use, substantially as herein set forth.
