PATENT JAMES A. TAYLOR, OF LIMA, INDIANA.

ROAD-SCRAPER AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 570,885, dated November 3, 1896.

Application tiled March 5, 1896. Serial No. 581.997. (No model.) i

To all whom, it may concern.-

Be it known that I, JAMES A. TAYLOR, a citizen of the United States, and a resident of Lima, La Grange county, State of Indiana, have invented certain new and useful Improvements in Road-Scrapers and Carriers, (Case C and mypreferred manner of carrying out the invention is set forth in the fol lowing full, clear, and exact description, terminating with claims particularlyspecifying t-he novelty.

This invention relates to road-Scrapers and carriers, and more especially to that class thereof known as self-loading carts and the object of the same is to produce improvements in the details of construction of devices of this character.

To this end the invention consists in a roadscraper constructed substantially as hereinafter described and claimed and as shown in the accompanying drawings.

Reference is made to United States Patents No. 552,936, dated January 14, 1896, and No. 555,270, dated February 25, 1896. In these patents are shown details of construction somewhat similar to those set forth below, but no claim is made in the present case to anything covered by the claims in the patents hitherto issued.

Referring to the accompanying drawings, Figure l is an elevation taken from the left side of the machine complete, showing the same as carrying three scoops or Scrapers, the forward one of which (lettered S) 'is illustrated in the act of scraping or taking up earth, the second one of which (lettered C) is shown as at a carry, and the rearmost one of which (lettered D) is illustrated as in a dumped position. (The remaining views omit the arch carrying the seat, as well as the front wheels.) Fig. 2 is a similar View and with the parts in the same positions, but taken from the left side of the machine at a point just inside the left side bar of the framework, and thus showing certain parts in section. Fig. 3 is a plan view of the machine Vshown as going in the opposite direction and as in the views above. Fig. 5 is a cross-section of the scraper C, taken on the line-5 5 of Fig. 3. Fig. 6 is a perspective detail of a modiiied form of the arch. Fig. 7 is a perspect-ive detail showing a modified form of the rear locking device. Fig. 8 is a plan View of the front axle and hounds. Fig. 9 is a per spective detail showing one of the blocks and its pivoted catch, which forms the bearing for the stub-shaft on the scoop.

In the said drawings the main framework comprises right and left longitudinal side bars R and L, suitably connected at proper intervals and supported by the rear axle A, carrying main wheels at its extremities, and having at their front ends arches cmi pon which is mounted the drivers seat d.

F is the front axle, carrying at its extremi ties the forward main wheels and connected at its center by a king-bolt and fth-wheel f with similar parts at the forward ends of the arches a, as will be understood.

II are hounds attached to the front axle,

and T is the tongue, preferably bolted, as at ,any other suitable framework may be substivtuted for that shown and described.

The machine herein illustrated has three scoops or Scrapers .mounted'between the side bars of the framework, and it is myintention to so construct it; but it will be obvious that each machine could carry a greater or less number of Scrapers, according to the amount of work to be done, the roughness of the earth at the point being treated, the strength of the team, and other conditions. Although I have not shown it, there is preferably a narrow platform extending along one or both sides of the framework and on which stands the operator who is to manipulate the levers described below, while the drivers sole duty is to co'n-` trol the team, drive tothe proper points and at proper times, and stop the machine when it is desired to dump.

I might here add that the parts described below are of any desired sizes, proportions, and materials, and the exact shape of the parts is immaterial, except that they should conform with the constructions recited in the claims, as will be understood.

In all cases the letter S designates a scoop or scraper (or the parts thereof) which is scraping or in the act of taking up earth. C is one that is at carry, by which I mean that when in this position the earth so taken up can be transported bodily by the machine,

and D one that is dumped and held dumped or in the act of being dumped, so as to discharge the contents of the scoop at the dumping-point.

Secured to and rising from the side bars of theframe are blocks 1, which have cut in their upper ends transverse notches 2, which form bearings, and these blocks are also longitudinallynotched, as at 3. In said notch 3, at one side of the bearing 2, is pivoted on a transverse pin -t a catch 5, adapted to swing down into the notch 3 and close the upper end of the bearing 2, the free end of this catch being held in place by a pin or other removable device G.

7 is a stron g arch (a modification of which is shown in Fig. G) whose center stands normally across and above the scoop and whose ends 3 turn downward and are provided with outwardly-proj ectin g stub-shafts 9, which are j ournaled in said bearings 2. This arch may be made in one or more pieces, as desired, and its center may be bowed slightly upward, as shown in Fig. 3 at S, or it may be straight, as seen in Fig. G.

10 is the main lever, secured rigidly, as by bolts, across one end of the arch. In the drawings it is shown at the left end when viewed from above, as in Fig. 3, although it will be obvious that it could be placed at the right end and all the levers be on this side of the machine. This lever is held firmly to the arch by a brace 11, attached to the lever and extending from its body obliquely across the arch, bowed slightly upward, and rigidly connected with a slotted arm 12, which projects forward from the other end of the arch the same as does the forward end of the lever 10, which latter is also slotted. livoted in the front end of each. slotted arm is a link 13, whose body moves th rough' a guide, hereinafter described, and whose lower end is pivoted to the side of the scoop 14. IIence when the handle of the lever is drawn to the rear the scoop is raised from the scraping position S to the carry position C, and during such movement the upright portions 3 of the arch pass over the supporting-pivots 9, by which it will be seen that the weight of the scoop can be very easily raised, and after being raised is firmly held in the bearings.

15 are tongues projecting to the rear and downward from the rear end of the right slotted arm 12 and from the lever 10, the tips of these tongues engaging sockets 16 in the sides of the scoop when the latter is at carry.

17 are other tongues, which may be fastened to and project upward from the sides of the scoop and which are adapted to engage sockets 18 in the right tongue 15 and in the lever 10 when the scoop is at carry. These tongues and sockets will firmly prevent lateral or longitudinal movements of the scoop both while at carry and while being dumped or after having been dumped, because in the act of dumping the scoop does not change its position with relation to the arch and lever.

20 is a curved and preferably metallic sheet located just forward of each scoop when the latter is in its carrying position and preferably having its extremities 2O bent to the rear, the function of this sheet being to guard and prevent the exit of the dirt from the scoop at this time. This sheet is supported by rods 21, which may have slotted ends 22, connected adjustably by bolts 23 with the side bars of the frame, or which may have their ends held by such bolts adjustably beneath clips 25, carried by said side bars. There is one guard for each scoop, as Will be clear. Y

Projecting inward from the lower ends of the upright portions 8 of each arch are pins 30, which engage slots 31 in the forward ends of a U-shaped bail 32, whose side bars are pivoted, as at 33, within the framework and whose rear member 34 stands across in rear of the scoop and has rising therefrom two guide-lingers 35.

36 are hooks projecting rearward and downward from the upper rear corners of the scoop and adapted to pass over this bail j ust inside said guide-iingers, and 37 are lugs located just beneath these hooks and in position to pass under the transverse portion of this bail when the scoop is in it-s scraping position. In the act of dumping the scoop and when it is turned around the pivots 9 these hooks 36 rise off the bail 34E and the lugs 37 pass by such bail, while at carry the hooks rest upon the bail and support the rear end of the scoop, and in moving the scoop to a scraping position (as described below) it slides bodily to the rear, so that the lugs 37 pass under the bail and prevent the rear end of the scoop from accidentally rising or being thrust farther rearward, while at this time the pins 30 raise the slotted front ends 32 of the bail and cause the rear side 34E of the latter to descend slightly, as will be seen in the drawings at S in Fig. 2. A slight modification of this construction is shown in Fig. 7, wherein the guidelingers, hooks, and lugs are dispensed with, and in their place is substituted the following construction: The rear portion 34 of the bail carries adjacent each rear corner of the scoop an upright finger 35', and the corner of the scoop has a horizontal loop 37 projecting to the rear and a hook 36' beneath it. This view shows in full lines the scoop in a scraping position,.at which time the bail is drawn tightly into the hook 36 and the nger 35 projects obliquely through the loop 37', so as to prevent the rear end of the scoop from rising. In dotted lines the parts are shown with the scoop at a carry, at which time the bail IOO TIO

IZO

has passed out of the hook 36' and the finger 35' rises straight upward through the loop 37', from which it may be bodily raised in the act of dumping.

The numeral 40 designates a long hook projecting forward from the rear of the scoop at its center, and this hook engages a catch 41, carried at the center of the arch 7.

42 is a thumb-lever carried by the main lever, and 43 is a rod for swinging the tip of this hookout of said catch. It' the hook engages the right side of the catch, as seen in Fig. 3 at C, the rod 43 operates a pivoted pawl 44, so that pressure on the thumb-lever 42 will move the tip of the hook to the right; but if the hook engages the left side of the catch the construction will be as shown in Fig. 6, wherein the inner end of the rod 43 has a slot 46 sliding over a pin on the catch and has a lip 47 at its free end so located as to disengage the hook from the left side of the catch. It will be clear that either Yconstruction may be employed without departing from the general principle. Vhen the scoop is raised from a scraping position to a carry, the catch moves backward until it e11- gages the hook 40. This holds the scoop from falling, and when the same is dumped by the main lever the catch, by engaging the hook, causes the rear end of the scoop to be raised bodily around the pivots 9. v has been moved to its completely-dumped position, a hook 48, carried by the side bar of the frame, engages the main lever 10 to prevent a return movement of the scoop, and this hook is disengaged from the lever when it is desired to throw the scoop back to a carry.

At each side of the scoop or scraper 14, near the front end thereof, is secured a hook 50, and connected therewith is a strap 51, eX- tending longitudinally of and slightly remote from the scraper, so as to form a guide for the link 13, as'above mentioned. Said hook is adapted to engage with another hook 52, (best seen in Fig. 4 at 8,) whose body is L- shaped and is pivoted at its angle at 53 to the side bar of the frame, its upright bar being pivoted to a slide 54, which is adapted to move longitudinally through the slot 3 in the block 1. This slide has-a pin 55, engaged by a cam 56, which is secured to the upright portion of the end 8 of the arch 7, the construction being` such that when the scoop is moved from a scraping position to a carry the cam pushes on the pin and shoves the slide forward, whereby the uprightarm of the hook 52 is pushed forward and the hook itself is caused to rise, this movement lifting the hook 50 and assisting in the eleva-tion of the mouth of the scoop. Vhen the latter is turned on its pivots 9 for the purpose of dumping, the hooks 50 and 52 do not engage each other.

57 is a spring carried by the side bar of the framework and pressing the hook and slidev in proper direction, so that when the scoop is moved from a carry to the scrapingposition the spring pushes the slide back with its pin Vhen the scoop.

in contact with the cam and permits the proper movement of the hook 52 to( engage it with the hook 50 on the scoop'. The latter on reaching its lowermost position, ready for taking up earth, is therefore held by the engagement ot' the hooks with each other. slight modification of this construction is shown in Fig. 2 at D, wherein the hook 52, although pivoted at 53', is not of L shape, but has an arm 53" connected with the slide 54 in about the manner shown, the operation of this construction being practically the same as above described.

A team is hitched to the tongue, the driver takes his seat, and the machine is driven to the point where it is desired to take up earth. One or more of the Scrapers are then lowered to the scraping position and the machine driven forward, so that loose earth from the surface of the ground will be taken into the several scoops, which may be thus lowered. When each scoop or scraper is filled, the attendant moves the lever 10 backward and the scraper is drawn to a carrying position wherein the guard lwill prevent the earth from running out of the scoop. All of the scoops having been iilled, the machine is driven to the'dump', and when it has arrived at the proper point the assistant raises the main levers 1Q to.

dump the scoops, as will be clear. The hooks 48 hold the scoops in dumped position, after which themachine is driven back to the place where the scraping is to be done, and the entire operation is repeated. This is done by disengaging the hook 48 from each lever and throwing the latter to the rear, so as to bring the empty scraper again to a carry. Then the thumb-lever 42 is manipulated to disenupper ends forming bearings and also provided withlongitudinal notches in their upper ends, a catch pivoted at one extremity in the latter notch at one side of the bearing and having its body passing across the bearing, and a pin holding the tip of thecatch removably in place; of an arch having stubshafts journaled in said bearings, a leverconnected with said arch, a scoop also connected with the arch, and means for holding the scoop in any one of several positions, as and for the purpose set forth.
