SPECIFICATION forming part of Letters Patent No. 655,404, dated August 7, 1900. Applicationfiled P 28,1900. Serial No. 6,803. (Nomodet) T0 at whom it may concern:

Be it known that I, MATTHEW H. JOHNSON, a citizen of the United States, residing at Goncord, in the county of Merrimac and State of New Hampshire, have invented certain new and useful Improvements in Road Breaking and Gouging Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to road-breaking machines more especially adapted for winter use, the object being to facilitate the breaking of streets and highways in rural districts and to gouge out gutters or ditches and level off pitch-holes. In towns and cities the invention will also be found serviceable. I

The invention consists of certain adj ustable wings of novel form and construction, together with their operating mechanism and means for attaching the wings to an ordinary sled, as fully set forth in the following speci fication and claims and clearly illustrated in the drawings forming a part of the same, of which Figure 1 is an elevation showing a portion of the side of a sled to which my improvements are attached, Fig. 2 being a sectional elevation showing a detail of my invention on an enlarged scale. Fig. 3 is a broken cross-sectional view showing a portion of the body of a sled and my improved wings with their connections, Fig. 4 being a broken plan view showing a portion of the body of a sled with my improved wings and their adjusting mechanism. Fig. 5 represents in perspective quire, and the machine will Work equally as well in light, damp, or compact snow, is most simple in construction and easily manipulated, yet strong, durable, and serviceable.

Referring to the accompanying drawings, A is the runner of a sled, and B indicates the floor-boards,which r'un crosswise of and are secured to the longitudinal rails C, forming the body-frame of a sled. Instead of connecting the Wings or scraper directly to the sled-body I consider it preferable to provide a stout plank D and attach the same transversely to the under side of the rails C by means of bolts or rivets d, as seen in Fig. 4, said plank D being permitted to project at each side of the sled-body for the convenient adjustment of the wings at the desired angle. The ends of the plank D are curved, as seen in Fig. 4, and provided upon opposite sides with curved metal plates E, which are secured thereon by rivets e, and with a metal yoke F, secured by bolts G to opposite edges of said plank, the transverse or end portion f of said yoke being curved to correspond with the curved plates E and separated from the latter the proper distance to form an opening for the reception and adjustment of one of the Wing hangers or supports H, the hangers or sup ports H, carrying the inner or adjacent ends of the wings, being secured to'the plank at fixed points, as shown, and forming the radius of the curved ends of the plank, as well as the plates E and end portion f of the yoke F. Each pair of hangers H H is provided with one or more perforations h for the reception of a bolt'I, and the studs h of the hangers H pass upward, one through each of the curved passages S, in which they may be secured at the desired point by a threaded nut 7L2, while the studs k of the hangers H pass upward through a perforation in the plank D and are secured therein by a threaded nut 71 J indicates my improved adjustable wings or scrapers, which are loosely connected at their top to the rods or bolts I by suitable strapirons K, firmly riveted to said wings. The inner or adjacent ends of the Wings J are separated but a couple of inches, more or less, and their under portions are cut away, as at j in Fig. 3, thus forming an arched passage.

for the surplus scrapings of snow or ice which shall have been drawn to the center of the road by the wings. The under portion of the outer end of each wing J is also cut away, as in Fig. 3, and the principal working edges of the wings are provided with an iron or steel face-plate L, as shown in Figs. 1 and 3.

M indicates extension-arms which are useful in leveling OK the the ridges of snow which tend to form beyond the outer ends of the wings when the snow is crowded from the center of the road outward and which would drift back into the road when high winds prevail. These arms M are pivotally attached, as at m, to the wings J and rest when in use upon the iron N, secured by bolts or rivets n to either wing J, and are held in place by a swiveled button 0, as seen in Figs. 3 and 4, and when not required for use said arms may be elevated after first turning the button 0 to the position shown by dotted lines in Fig. 3.

As a means of adjusting the wings to the required vertical angle a chain or cable P may connect the forward side of each wing J with a suitable taking-up or winding device attached to the sled-body at a point forward of said wings. To this end I show an eyebolt p, secured to a wingJ and provided with a link 19, to which one end of the cable P is attached, the other end of said cable being secured to a drum or sleeve Q, said sleeve having at one end a ratchet-wheel q and at its opposite end a perforated wheel q, one of said sleeves being mounted upon a journal 7*, formed at each end of a square bar R, secured by suitable loops T to the floor of a sled, as seen in Fig. 4.

A nut 7" may be threaded to each journal 1' of the bar R for holding the sleeves Q thereon, and a suitable bar may be inserted in either socket or perforation g of the wheel q for winding the cable P upon the sleeve Q, or vice ve rsa, said sleeve being held station ary by means of a pawl U, pivotally attached, as at V, to either side of the sled-body, one end of said pawl being adapted to engage the teeth of the ratchet-wheel q, while its opposite end may be pressed downward for disengaging the pawl from the ratchet and permitting the rotation of said sleeve for varying the vertical angle of the wing J.

By thepeculiar form and adjustment of my improved scrapers or wings this machine not only plows the snow from the sled-tracks, but also presses it down, leaving a smooth compact road-bed which will wear well, the sun not exerting so deteriorating an effect upon a hard compact surface of snow as it will upon a more poroussurface, such as follows the common practice of road-breaking, a fact which is readily appreciated by the pubhe who use the highways and streets.

For gouging off the shoulders and filling pitch-holes this machine can be so gaged as to gradually remove the snow or ice and pack itfirmly into the depressions resulting from heavy teaming, or in cases where snow alone causes the unevenness the wings J can be so set as to accomplish the desired object at one operation. In breaking roads with my improved machine when the snow is light the wings may be set at right angles with the sled, as seen in Figs. 3 and 4; but when encountering heavier snow or drifts they are adj usted so that their outer ends incline rearward, and for filling pitch-holes, &c., the wings are inclined forward, so as to draw the scrapings into the center of the road, the surplus passing under the arched or cut-away portions of the adjacent ends of the wings, the foregoing adjustments being readily accomplished by the movement of the hangers H within the curved passage S at each end of the plank D, and by the use of this plank for supporting the wings it is obvious that a machine adapted for breaking roads andembodying the foregoing improvements may be readily contrived where an ordinary four-rum nered sled is obtainable.

Having described my improvements, what I claim is- V 1. .In a road-breaking machine, a pair of wings or scrapers located normally in transverse alinement and pivotally connected to the machine at or near their adjacent ends,

means for adjusting said wings. at an angle forward or backward, and meansfor elevating the lower edge of saidwings comprising rotary drums, ratchets and pawlsfor controlling the same, and a chain or cable connect ing said wings and drums.

2. In a road-breaking machine, a pair of wings or scrapers having the lower corners of their adjacent ends cut away and located normally in transverse alinement and pivotally connected to the machine at or near their adjacent ends, means for adjusting said wings at an angle forward or backward comprising movable hangers, and meansj or elevating the lower edge of said wings comprising rotary dru ms,- ratchets and pawls for con trolling the same, and a chain or cable con necting said wings and drums. V

3. In a road-breaking machine, a pair of wings or scrapers disposed transversely and in normal alinement, said wings being pivotally attached to themachine near their adroe.

jacent ends and having their lower adjacent corners cut away and the outer portions of their lower edge formed upon a higher plane I than are the central working portions, means for adjusting said wings at an. angle forward or backward said means comprising movable hangers, means for elevating the lower 5 edge of said wings comprising rotary drums,

ratchets and pawls. for controlling the same and a chain or cable connecting said wings and drums, and extension-arms pivotally attached to said wings, substantially for the purpose set forth.

4. In road-breaking machines, a transversely-disposed plank bolted to the under side of the body portion and projecting beyond the sides of said machine, a pair oftransverse wings or scrapers having their adjacent ends pivoted at a fixed pointto said plank, suitable hangers pivotally attached to said wings and adapted for adjustment near either end of said plank and for securing said wings in alinement or at an angle therewith, and means substantially as shown for drawing the lower edge of said Wings forward, substantially for the purpose set forth.

5. In a road-breaking machine, a pair of wings or scrapers pivotally connected near their adjacent ends to said machine and disposed transversely in normal alinement, the under corners of said adjacent ends being cut away and said wings being adapted for vertical and horizontal adjustment whereby the snow may be closely packed at most desirable points in the road. 7

6. In a roadbreaking machine, a pair of wings or scrapers pivotally connected near their adjacent ends to said machine and disposed transversely in normal alinement, the lower edge of that portion of the wings which extends beyond the machine being formed on a higher plane than that of the remainder of the working edge of said wings, extensionarms pivotally attached to the outer ends of said wings, and means for adjusting said wings vertically and horizontally whereby the ridges of snow which usually form at either side of the sleigh-tracks may be lev eled.

In testimony whereof I aflix my signature in presence of two Witnesses.

MATTHEW H. JOHNSON.
