ATTORNEY FRANK PHILIP, OF STOCKPORT, NEW YORK.

ROAD-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 621,3? 1, dated March 21, 1899.

Application filed September 25,1897. Serial No- 652,963. (No model.)

To all whom it may concern:

Be it known that I, FRANK PHILIP, a citizen of the United States, and a resident of Stock port, in the county of Columbia and State of New York,have in vented certain new and usef Lil Improvements in Road-Scrapers, of which the following is a specification.

My invention consists of improvements in the construction of road-scrapers, wherebyit is designed to provide simpler, cheaper, more efficient, and more easily-operating scrapers, as hereinafter described,reference being made to the accompanying drawings, in which Figure 1 is a plan View of my improvedroad-scraper with a part in horizontal section. Fig. 2 is a side elevation. Fig. 3 is a detail in plan View. Fig. 4 is a plan View in a folded condition for storing compactly, some parts being omitted. Fig. 5 is adetail of one of the wheels in side elevation. Fig. 6 is a plan of the said wheel attachment, partly in horizontal section. Fig. 7 is a side elevation of a lateral coupling-bar between the moldboard and the beam. Fig. 8 is an end elevation of the moldboard and a-platform for the driver to stand on when more weight is required on the moldboard, and Fig. 9 isafront elevation of part of the moldboard with an extension attachment that is desirable to employ in some cases.

A suitable metallic beam (1 is provided of similar character, as a plow-beam, preferably of channel-iron form in cross-section. About the middle of its length it is mounted on a suitable standard 0, which at its lower end has the laterally-projecting axle d, on which a carrying-wheel e is pivoted, being confined thereon by one or more washers fand a linchpin g, said washers preferably being secured so that the wearing contact is between them.

. One is made to turn with the hub of the wheel by the spur and notch at h, and the linchpin is notched into the other so as to prevent it from turning. This provision is made in order that the wear, which is excessive owing to the side thrusts on the moldboard, may be spent on the washers, which can be readily renewed from time to time. a flange i for cutting into the ground for a holding to resist the side thrust of the moldboard.

The moldboardj is a long plate shod with about without doing work.

The wheel has steel along one edge and is supported at an an gle of forty-five degrees to the beam and under the rear portion of the beam suitably for gathering the plowed-up earth at its forward end and shoving it over into the roadway behind the wheel e. At the back of the moldboard asuitable distance from the forward end a metallic bracket is is attached, in which there is a vertical slideway groove Z, and in this groove there is a sliding plate 112, which carries an axle n, on which the small wheel 0 is mounted for carrying the forward part of the moldboard j when the machine is to be moved The sliding plate m has an upward extension 19, terminatingin the toothed sector q, in the axis of which a hand-lever s is pivoted, said lever having a laterally-projecting arm 16 radial to the pivoto and at its outer end connected bya rod to with an eye-stud a: on the bracket 70, so that when the lever is shifted to the left hand the wheel 0 will rest on the ground and the moldboard will be raised above the ground, and vice versa. A pawl y locks the lever in the different positions. The pawl is provided with the usual hand-lever z and spring a for controlling it. Near the other end of the moldboard it is provided with a socket b, fitted to slide up and down on a king-post c, pendent from the rear end of the beam at, and is connected by a chain d With the short lateral arm e of a hand-lever f, pivoted at g in the axis of a notched sector It, said lever having a pawl 71 for locking the lever in the different positions in which it is to be set. The pawl t" is provided with the usual hand-lever] and spring is for controlling it.

The kingpost is clamped in a vertical groove in the side of the beam a by a cap Z and suitable bolts, said cap and the notched sector h being formed in one piece for simplicity and economy of construction. It will be seen that by shifting the lever f to the left hand the moldboard can be lowered to its work, while the reverse movement of the lever will raise the moldboard out of action. Between the king-post and the carrying-wheel e the beam is upwardly curved for free passage of the scrapings under it. To maintain the moldboard in the proper angular relation to the beam ,the diagonal stay-bar m is employed to connect the moldboard in the vicinity of the wheel 0 with the beam a near and preferably in advance of the point where the beam is mounted on the carrying-wheel t'. This staybar is preferably connected detachabl y to facilitate folding the machine compactly for storage, as represented in Fig. l; but it may be permanentlyconnected, ifdesired. It may be connected in various different ways, but in the plan herein represented the forward end has a hook-head 91 inserted through a slot 0 in the vertical flange of the beam when presented with the bar swung well forward of the normal position and adapted to have substantial holding when said bar is returned to said position.

The rear portion of the stay-bar is bowshaped suitably to reach over the top of the moldboard and down to a bearing-point behind for high range to clear the upgathered matters on the moldboard. A spur p of the forward face of the lower portion of the staybar rests on the upper edge of the moldboard to maintain the proper altitude, and below said spur said face is grooved 01' notched, as indicated at q, to engage with ribs 8' to prevent upward escape of the bearing end under severe stresses. A horn n of the bracket 7c and the foot-piece of the bracket confine the stay-bar against escape from the ribs 8 either way laterally. It will be seen that these contrivances afford simple and reliable means of detachable connection of the stay-bar without bolts, hooks, or the like requiring manip ulation.

It is at times desirable to have longer reach of the moldboard in the direction for gathering the upturned soil, for which I attach an extension-plate 25 by lapping a portion of it behind the end portion of the main board and bolting thereat, as shown in Fig. 9, or in any approved way, said extension being preferably of less width than the main board, at least in the part projecting beyond the latter, to prevent overloading the moldboard when the quantity of loose-earth in range of the extension is large.

The beam at is of channel-bar form for the most part of its length, with the two flanges projecting sidewise, as will be understood by looking at the sectioned part of the beam in Fig. 1; but in the part forward of the section it also has a flange f at the lower edge on the opposite side to the channel, which, together with the lower flange on the other side, has bolt-holes 10, preferably in the form of notches, in the edges for convenience in form-.

ing them in the casting, and the tongue 4) is bolted onto the upper side of flange f, as represented in Figs. 1 and 2, when two horses are to be employed; but for a three-horse gear the tongue is detached, the two transverse bars w are bolted onto the under side of beam, and the tongue is bolted onto the extremities of the bars to, as shown in dotted lines in Fig. 1 and shown in part in full lines in Fig. 3, the middle horse being then placed directly in front of the beam. The bars w are stayed by a diagonal brace 112 The evener-coupling jaws as are formed on the end of the beam. To prevent bolts .23 from working loose in the slot holes when the tongue is adjusted for two horses, the bars 20 are retained, as shown in Fig. 1, so that the bolts will oppose the tendency of said bolts :0 to work loose.

A platform a is mounted on the back of the moldboard for the driver to stand on when it is desirable to add his weight for better effect. The inner edge of the platform rests against the rear face of the moldboard above the stiffening-flange b of the moldboard, and hook-stays 0 secured to the respective ends, engage with eye-studs (l of the moldboard for a simple means of detachably connecting said platform. The floor is preferably of grating to allow matters thrust over the moldboard to escape.
