Serial No. 644,777.

To all whom it may concern:

Be it known that l, Piins'roN L. HOLCOMB, a citizen of the United States of America, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Loading Apparatus, of which the following is a specification.

My invention relates to an improved apparatus for hauling earth, excavated by means of scrapes, and loading it into the wagons with a minimum of delay or expense, and the chief object of my invention is to provide an apparatus by means of which the draft animal or apparatus, which drags the scrape, can be utilized to both elevate it and automatically dump its contents into chutes or hoppers from which it may be loaded directly into wagons.

A further important object of my invention is to adapt my apparatus to act as a quick unloading device so that the scrapes may be continuously elevated and dumped into one or more hoppers which hold the earth until a wagon is ready to receive it and be loaded therefrom without labor and delay.

My invention further comprises other novel features of construction such as the mechanism for the convenient transportation of the apparatus from point to point; the novel means for permitting the drag rope for the scrape to pass through the dumping apparatus; the novel construction of the scrape; the arrangement of the guide platforms with the inclined elevating ways leading to a top dump; and other features, all of which are hereinafter more fully described, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of my improved apparatus. Fig. 2 is a sectional elevation along the line m-m of Fig. 3. Fig. 3 is an end elevation, and Fig. L is a top plan View of Fig. 1. Fig. 5 is a detail view of the rear end platform showing the wheel supports therefor. Fig. 6 is a detail vertical sectional view through the front platform with its wheel supports in position. Fig. 7 is a plan view of Fig. 6. Fig. S is a detail View of my improved form of scrape.

Similar reference numerals refer to similar parts throughout the drawings.

My apparatus in the preferred form illustrated comprises a strong frame-work consisting of a pair of parallel horizontal bottom bars l which are spaced about four feet apart and near their centers have connected to each a pair of vertical uprights 2, which uprights are cross connected at the top by the braces 2l. At each end the bars l are connected to incline members t and 5, which members are, at their upper ends, bolted to a heavy dumping timber G. There are two of these dumping timbers, each of which is bolted to the iiprights 2 on its respective side of the frame. These members 6 are depressed at the center and provided each with a piu 7 projecting inwardly from its side. A metal strip 8 preferably extends along the top edges of the incline members l and 5 and over the top edge of the dumping members G, forming metal tracks over which the wheels 9 on the scrapes l0 run. The incline members 4 and the rear ends of the bars 1 are rigidly attached to a rear platform 11, having at each side inwardly curving guide members 12 which direct the sides of the scrape into position for the rollers 9 thereon to ride up the incline ways, and in a similar manner the forward ends of the bars 1 and the incline members 5 are connected to a platform 18 also having incurving guide members 12.

The platform 11 has a pair of metal straps 14 attached thereto and bent over to form a bearing for a bent axle 15, the ends 1G (Fig. 5) of which axle are bent outwardly at right angles and have mounted thereon wheels 17. A lever 1 8 is connected to a portion of the axle that lies parallel with a bar 1 and is adapted to be caught under an angle fastener 19 attached to the adjacent bar 1, as seen in Fig. 5. Then the lever is caught in this position the rear platform is lifted on the wheels as fulcrums and is sustained by the wheels ready for transporting the apparatus. The forward end of the apparatus is provided with a pair of bolts 2O which are adapted to engage a cross bar 21 (Figs. G and 7), carrying at its center a king bolt 22, which bolt connects with the cross members 23 which support an axle 211v on which wheels 25 are mounted, and to which are connected the hounds 26 to which the tongue 27 is fastened. lVhen the apparatus is ready for service the forward wheel attachments are readily disconnected therefrom and the apparatus left resting solidly on the ground as shown in Fig. 4, the lever 1S being disconnected from the clip 19.

Referring to Figs. 2 and 3, itwill be seen Patented Mar. 19, 1912.

vso

that I provide a pair of hoppers 28 and 29 which are suitably attached at each side of the frame to the uprights 2 and are disposed at an incline with their lower ends normally ,closed by doors 30 which are hinged by pins 31 in metal straps 32- attached to the top of the hopper. Each door is also provided with a staple or strap 33 in line with a similar staple or strap 34 at the lower end of the hopper, and I provide a pivoted lever 35 which carries a pin 36 adapted to be passed down through the staple or straps 33 and 34 to hold the .door closed. A strap 37, connected to the door, serves as a guide for the lever 35. It will be noted that the two upper ends of the hoppers 2S and 29 are juxtaposed but are not directly connected. Normally they will be held in abutting position by means of coil springs 38, which are set in slots 39 formed in the cross braces 3 and adapted to engage and press against the bolts 40 which are connected to angle irons 41 bolted to the tops of the uprights Q, and pass through the slots adjustably connecting the uprights to the braces 3. These springs tend to force the uprights together and hold the adjacent edges of the chutes in juxtaposition while not weakening the general strength with which the apparatus is assembled. The side edges of the abutting ends of the hoppers are curved or grooved, as seen at 42 (Fig. 3), so as to readily guide a rope or cable 43, which is attached to the scrape 10, in between the hoppers so that it will force them apart and pass between them as the draft animal passes through the apparatus in drawing the scrape up the incline ways. The rope or cable 43 is attached to a bail 44 that is pivotally fastened to the inside forward ends of the scrape. The handles 45 for the scrape are also preferably attached inside of the side members so as to leave exposed on the side only the rollers 9. The forward ends of the scrape are provided with notches 46 which,'as the scrape rides down into the depression on the dumping members 6, will engage the pins 7, as seen in Fig. 2, and will cause the scrape to turn over and dump its contents into the hoppers and pass down the other incline in reversed, inverted position, as shown in dotted lines Fig. 2. The members 2 may be further strengthened by braces 47 and the end boards 48 of both platforms will be beveled off so that the scrape will readily ride onto the platforms.

In practice, the scrape is filled with dirt or material in the usual manner as it is drawn along by the draft animal, which is then driven through the apparatus. As the animal passes through, the scrape is guided onto the incline ways 4 or 5 by t-he guides l2 and its rollers 9 cause it to run up the inclines without much friction or increased draft. At the top of the incline the scrape is turned over and dumped in the manner described and its contents will fall equally into the hoppers 28 and Q9. The teams for conveying it away will be driven under the discharge ends of said hoppers and the wagons loaded by releasing the doors 30 and discharging the hopper contents thereinto. l/Vhen it is desired to dump into either hopper 28 or 29, I provide a plate 49 which may be dropped into the hopper not to be used so that it will assume the inclined position therein shown in dotted lines in Fig. 3. This will cause all the material to be thrown into the hopper that it is desired to charge.

My apparatus can receive loads from either end and provides for a continuous operation in loading-the hoppers 2S and 29 and a quick operation in unloading the hoppers into wagons for hauling away the eX- cavated material, thus permitting the maximum economy in operation both of the eX- cavating and hauling equipment.
