SPECIFICATION forming part of Letters Patent No. 744,856, dated November 24;, 1903. Application filed May 6, 1903. Serial No. 155,875. (No model.)

To rtZZ whom, it Ina/y concern.-

Be it known thatI, JAMES MAXEY BROOKS, a citizen of the United States of America, and a resident of Molena, county of Pike, State of Georgia, have invented certain new and usefullmprovements in Wheel-Scrapers,of which the following is a full, clear, and exact description, reference being had therein to the accompanying drawings, in which Figure 1 is a perspective View of the machine loaded; Fig. 2, a plan View of the same; Fig. 3, aside view of the same, the near wheel being removed; Fig. 4:, a view in detail showing the position of some of the parts while in the act of dumping; Fig. 5, a detail perspective of the end gate; Fig. 6, a view of the machine in the act of loading, the near wheel being removed; Figs. 7, 8, 9, and 10, detail views hereinafter described; Fig. 11, a side elevation showing the manner of connecting a pair of scrapers when used in tandem; Fig. 12, a detail perspective of the frame used in connecting the scrapers when used in tandem; and Fig. 13, a side elevation showing the apparatus converted into a log-cart, the

near wheel being removed.

The object of this invention is principally to improve the load elevating and dumping devices and also to render the machine readily convertible into a tandem excavator,a log'cart, a two-wheeled dump-cart, and a wagon, thereby especially adapting the machine for general contracting-work.

The invention also has other objects in view, which will appear in the course of this specification.

Referring to the drawings by reference-letters, the draft appliance consists of a tongue 0., attached at its rear end to a cross-bar b, which is braced to the tongue by the draftbars 0, which are long enough to extend back to the rear of the arch of the axle d and are each provided with an upward-extending arm e at its rear extremity, these arms extending up above the spindles of the axle and being pivotally connected by removable horizontal bolts f to the rear ends of side bars g, which are parts of a frame or yoke consisting of said side bars and a front crossbar h.

The side bars g are rigidly attached to the vertical parts of the arch of the axle and are braced by the forwardly-inclined braces 2', rigidly connecting the bars 9 to the axle-spindles, whereby said frame and the axle move as a single frame.

Journaled in suitable brackets j, attached to the side bars 9 near the front bar h, is a rock-shaft 70, extending entirely across the front of the machine parallel to the front bar h, and rigidly attached to this rock-shaft is a stop I, which engages under the bar It and limits the movement of said shaft. The ends of said shaft beyond the side bars 9 are formed into cranks m, which carry brakeshoes n, which are adapted to bear upon the tires of the Wheels. One end of said shaft carries an operating-handle 0, which lies outside of one of the transporting-wheels and extends toward and a little below the hub thereof to be within convenient reach of the driver, who usually Walks along by the side of the machine.

Pivoted to the front bar It is a latch 19, which is adapted to normally engage under the projecting edge of a plate q, bolted on the rear end of the tongue, and whose handle 1" extends toward one side of the machine far enough to be reached by the driver without passing in front of the machine.

The scraper-pan s is pivotally hung about midway its length by vertical hangers if, bolted to the side of the scraper and extending up above the top edges of the same, removable bolts tt being employed to pivotallyconnect the upper ends of these hangers to the upturned ends 6 of the draft-irons.

The draft-hooks n engage draft-eyes to, attached to the sides of the pan, these hooks inclining upward and forward and being pivotally connected by bolts 00 to the draft-bars 0, each hook being provided with an arm y at its upper end which curves upward and rearward and normally rests upon the rear part of bar 0 and the forward end of a triplever e, which is pivotally supported on a shoulder-bolt .2 between one of the hangers tand the adjacent side of the scraper and whose rear end is pivotally connected at a to a bar b, pivotally supported at c on the side of the scraper and extending rearward beyond the scraper. The bar or lever e is slotted at d where its pivot passes through in order that it may have a limited longitudinal play when it is vibrated on its pivot, and thereby avoid binding.

To the rear end of each of the levers b is pivotally connected a link 6, which extends upward and forward and is pivotally connected to a standard f, loosely attached to the axle-spindle. Each of these standards f is provided with a bearing in its upper end, and in these hearings is journaled a transverse rock-shaft g, whose ends beyond said standards are each cranked and provided with a brake-shoe h to engage the surface of the wheel-tire. One end of this shaft g is provided with an operating handle or lever t", which lies outside of one of the wheels and extends toward the hub thereof. The han dles 0 and t are preferably at the left side of the machine.

To limit the depth of the cut, I employ suitable limiting devicesj, connecting the brace tor any other part of the frame carried by the axle in front of the same to the draft appliance. In the present instance I employ a chain and a plate 76, pivotally connected to the draft-iron by the bolt 00, which supports the pivotal draft-hook c, this plate 76' being provided with a series of holes for adjustment purposes; but it will be observed that I may employ any suitable adjustable devices in lieu of this chain and perforated plate.

In front of each hook o is mounted a downward-inclined bar Z, which terminates in front of said hook and the eye 10 and in line therewith, and which has its upper end rigidly connected to the draft-irons by one or more rivets m. The front edge of each of these bars Z may be sharpened somewhat, so that they will act as a cutter to cut roots and clods. These bars will also act as fenders to prevent clodsand stones interfering with the proper action of the hooks and eyes or loops. Each of these fenders or colters is braced by an upward and rearwardly inclined brace 41, connecting it to the draft-iron. This brace n is formed, preferably, by a downward continuation of the rear end of a bar 0, bolted to the side of the main draft-irons by rivets m and so. The forward ends of bars Z are carried around the front corners of the draftirons and bolted to the tongue, as shown more clearly in Fig. 2, thereby strengthening the weakest points in the draft-ironsnamely, the front corners thereof.

When the machine is in the act of loading, the parts are positioned as shown in Fig. 6- that is, the draft-hooks u are in engagement with-the loops w and their trip-arms y are oflf the trip-levers z, the levers y and b, which form a sort of toggle-lever, are in alinenient, and the brake-shoes and their shafts are in the position shown.

When the scraper is loaded and it is desired to elevate the same, the driver grasps lever 0 and presses it backward toward the hub until the brake-blocks bear firmly against the wheel-tires, whereupon the forward motion of the wheels will carry the arch of the axle upward and the upper end of the frame 9 h downward and forward until-the latch 19 engages plate g and latches the forward end of the frame down, whereupon the driver will release the handle 0. When the forward end of the frame is thus carried down, its rear end is elevated and carries with it the uprights e, on which is hung the scraper, thereby elevating the scraper to the position shown in Fig. 3, latch 13 holding it in that position while it is being transportedto the dumpplace. When the pan is thus elevated, the scraper swings forward and brings the hooks 'v to the rear ends of the loops or eyes, as shown in Fig. 3.

In dumping, the driver simply takes hold of lever t" and pulls it rearward to apply the brake blocks h to the wheels, which action carries the standards f forward and through the medium of the links a and toggles Z7 and z lifts the draft-hooks out of the draft-eyes. The continued movement for ward of the standards f then lifts the rear end of the scraper-pan and dumps the pan in the usual way by inverting it. After the pan is dumped it may be readily swung back into the position shown in Fig. 3 and be then transported back to the loading-place.

When itis desired todrop the pan to load,the driver simply reaches in and releases latch 19, whereupon the scraper drops to loading position. If desired, an end gate 1" may be employed to close the front end of this pan when it is elevated. This end gate may be convenientlypivoted upon the side barsg by means of bolts 8', the gate being provided with suitable side arms t for this purpose and suitable forward-projecting lugs 10', adapted to engage over the front edge of the cross-bar h to prevent the end gate dropping downward too far. Located and supported in this manner, the

.end gate automatically drops down in front of the scraper when the same is elevated by the downward movement of the frameg h, as shown in Fig. 3. When the said frame 9 his elevated and the scraper-pan drops, this end gate is lifted out of the way,as shown in Fig. 6;

This machine possesses a number of very important advantages. An important feature lies in utilizing the forward motion of the apparatus to both elevate the loaded pan and to dump it and to arrange the operating-handles at the side of the machine where theywill be within convenient reach of the driver, who usually walks along by the side of the machine. It will be noted that these handles are arranged substantially radial, so that they are always within easy reach of the driver no matter what position the brake-shoes may be in. It will be noted, further, that by pivotally hanging the scraper at a point well up and by employing the peculiar arrangement of devices shown and described for unlatching the draft-hooks all danger of the pan being prematurely dumped while being transported to the dump-place is avoided, for even though the front edge of the pan should engage an obstruction which would tend to dump it the draft-hooks would engage the forward ends of the draft-eyes and prevent the pan from being dumped, the draft-hook eyes being prevented from missing the draft-hooks by reason of the position of the draft-ho0ks and the elevated pointof pivotal support on the pan, as is evident from a glance at Fig. 3.

To convert the apparatus into a log cart or truck, as shown in Fig. 13, it is simply necessary to remove the pan by detaching its bolts to and the links (2. Then by hitching suitable chains 00 to the arch of the axle, the same being lowered, and passing said chain under the log to be transported, the front end of the log may be elevated by the elevatingbrakes and latched in that position and be dragged away.

To arrange a pair of scrapers in tandem, as shown in Fig. 11, itis simply necessary to use a supplemental frame y, (shown in detail in Fig. 12,) the forward ends of whose side bars are bent up and bolted to the standards 6, carried by the front machine. This frame extends rearward beyond the ends of the bars b and links 6' and is provided with a suitable strap orloop 2', into which the forward end "of the tongue of the rear machine may be bolted, this tongue being shortened in order that the two machines shall be brought close together andbesubstantiallyonemachine. Theframe y is wide enough to avoid interference with the free operation of the parts of the front machine, so that each machine will be free to operate as when used singly. These tandem machines are of great value where the length of the haul is so great as to make it advisable to increase the capacityof each machine or enable each team to double its capacity. Of course these tandem machines can only be employed in earth that is comparatively easyto excavate. It will be observed that the forward upward'turned ends of the side bars y are bolted to the uprights e by the same bolts fand u that attach these uprights to the hangers t and the side bars As shown in Figs. 2 and 3, a seat I) for the driver may be mounted on the roclnshaft g, which the driver may use while the load is being transported to the dump.

As will be observed, the seat normally inclines slightly downwardly and forwardly, whereby when the driver is in place thereon his weight will tilt the seat up to an approximately horizontal position, and thereby hold the brake-shoes 71. off the wheels.

In addition to limiting the depth of the cut, the chainsj serve another purpose-namely, to lift upward on the draft appliance, and thereby counteract the downward pull on the draft-hooks, whereby the draft appliance will be greatly strengthened.
