EXCAVATING AND LOADING APPARATUS.

Application filed September 2a, 1921, Serial no. 502,498. Renewed March 5, 1,923.

To all whom it may concern:

Be it known that Gnoncn WVEIDINGER, a citizen of the United States of America, residing at Mount Sterling, in the county of Madison and State of Ohio, has invented certain new and useful Improvements in Excavating and Loading Apparatus, of Which the following is a specification.

My invention relates to an apparatus for excavating loading and conveying earth, sand, gravel or similar materials. It is also adapted to be used for loading manures.

An object of my invention is the construction of an apparatus by means of which material may, by continuous movement and a single source of power, beexcavated, car: ried to a loading apparatus, elevated and dumped into a wagon or other conveying means.

A further object of my invention is the pivotal arrangement of a platform, one end of which will rest on the ground when the arms to which it is attached are in their lowered position and which will remain sub stantially horizontal while being elevated until tipped by contact with the tipping fin ers on an upright of the frame.

K still further object of my invention is the construction of a chute, a part of which is pivotally mounted to permit the discharge end to be raised and lowered.

A still furtherobject of my invention is to provide means on the scraper carrying platform to contact with the bail of the scraper to raise the platform to a dumping position.

These and further objects of my invention are carried out in an apparatus one form of which is shown in the acccompanyin drawings in which,

Figure 1 is a side elevation with the platform in a lowered position.

Figure 2 is a sideelevation with the platform in a dumping position.

Figure 3 is a front elevation with some of the parts cut away.

Figure 41 is a section on the line det of Figure 3, and

Figure '5 is a sectional detail showing the lugs to prevent the platform from tilting backward when it is elevated.

Figure 6 is a side elevation showing the platform in raised position with some of the parts omitted.

The base of my device comprises two sills or runners 1 and 2 made any suitable and 5 joined at the top of a crossbar 6.

These uprights may be made of steel or other suitable material and are supported in. position by braces 7 and 8, one end of each brace being joined to one of the uprights and the other end of each brace to the ends of.

the sill in any suitable manner such as by bolts. The uprights are further supported by a brace 9, the ends of which are attached to the sill 2, which is joined to the uprights 4; and 5 by braces 10 and 11. Pivotally connected to the upright 4? at 12 is a platform carrying arm 13. A duplicate arm 14 is similarly connected to the base of the upright 5. These arms may be braced by a rod 15 which has a function, in addition to its bracing function, which will be referred to latter. Pivotally suspended to the outer end of the arms 13 and 1 1- by platform. supporting arms 16 and 17 is a platform 18, having upturned sides 19 and 20 extending from the arms 16 and 17 toward the front of the platform. The platform 18 extends to the rear of the arms 16 and 17, and the end thereof may rest on the ground or any suitable'support. Extendingfrom forward of the middle of the length bf the platform is a bail 21 from the upper part of which run two rods 22 and 28 to lugs 24 and 25 to support the bail and for another purpose to be pointed out later. Extending across the front of the platform 18 is a bar 26. lVhen the apparatus is in the position to receive material to be conveyed the front of the platform 18 rests on the rod 15 and the ends of the bar 26 rest on the arms 13 and 14, thus making a suitable angle for the platform to receive advantageously the scraper filled with material, as shown in Figure 1. from the ends of the arms 13 and 14 as shown in Figure 5 and is prevented from tipping to the rear and thus causing the scraper with material to slide off by stops 2'7 and 28 on the arms 16 and 17. The usual scraper 29, having a bail 30 and handles 81 and 32, has attached thereto a cable 33 which runs over a roller 34 fixed in the bail 21, to a pulley 35 attached to the top of the support 9 and thence to a pulley 36. Suitable power may be applied to the The platform is pivotally hung the chute.

The shapeof these lingers. cause the front of the platform to be gradually may then have attached to it the cable to draw it on the platform. It may, however, be'filled by applying power to the cable and then by pulling it on to the platform until the bail contacts with the arms 22 and 23 which will cause the platform with the scraper thereon to be raised to the posi tion shown in Figures 2 and l. l romthe time the platform leaves the ground until the bar26 comes in contact with the fingers 37 and 38 it -Wlll'I'6lI1ZLll'l in a horizontal position. "lhis position maintained by suitably placing the armsand braces on the platform and regulating the length of the scraper bail. 3 As has been pointed out, the platform is prevented from tilting back; ward by stops oiithe arms which support it. When the platform comes in contact with. the'tilting fingers the front oi the platform is lowered, dumping the n'iaterial into it will be understood that my apparatus may be moved from place to place for use by attaching power to sills which act as runners, orin any other 'suitable manner.

While I have shown a scraper asthe implement to be used to excavate the material and to convey it to the carrying platform, it is understood that my invention also con templates using any form of device .to carry the material to be loaded to the elevating and dumping platform. g

It is further understood that my apparatus is Well adapted to loading manure 1919, .orthe patent to Allerecht, N0. 765,951,

of July 26, 1904.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is: l. An apparatus of the kind described comprising a suitable frame," uprights mounted thereon, arms pivotally"connected to said uprights, a material :carrying plat "form, means to connect said platform to said arms,'m eans'on said connecting means to prevent said platform 'i'roi'n tilting'b a '3kward when raised and to maintain said plat; form when raised in a substantially horizontal position, amaterial carrying receptacle adapted to be placed on said 'platiorm, af75. bail torsaid receptacle, bail abutting means" on said platform, power means attached to said bail to raise said platform, andfpi i'orm tilting'ineans. v 2. An apparatus of the kind; described comprising I a suitable frame, uprights mounted thereon, arms pivotally'connected to said uprights, a material carrying plat form, said platt'ormhaving arms, said platform arms pivotally connected to said-iirstmentioned arms, said platform arms hav -f ing stops thereon toprevent the backward tilting oi said platf-orm.beyond substantially horizontal position and'm'eans to raise and tilt said platform forward, I g k I90 3. An apparatus of thejkind described comprising a suitable frame, uprighh mountedthereon, arms pivotally connected to said uprights, a material"Carrying'platQ form connected-to said arms, said platform adapted to maintain substantially a hori; zontal position when raised,a material car-f rying receptacle'adapted to be placed on said.' platform, a bail'for'said receptacle, akbail abut-ting means on said platform, said'abut ting means adapted'to stop theforward. movement of said receptacle on'said plat form, power means attached to said. recep tacle to raise said, platform and'receptacle and platform tilting means on said receptacle. .7
