Application filed March 31, 1917. Serial No. 158,916.

To all whom may concern:

lie it known that 1, JOHN A- Nansen, a citizen of the United States, residing at Ne braska City, in the county of (ltoe and State of Nebraska, have invented a new and useful lioailing-Machine, of which the following is a. specification.

The present invention appertains to loading machines, and aims to provide a novel and improved appliance of that, character which is operable for loading wagons or other receptacles in. a thoroughly practical and el'licacious manner.

it is the object of the invention to provide a loading machine embodying means onto which the dirt or other matter to be loaded can be shorelcd or dumped, and adapted to be raised so that the wagon. or other receptacle can be moved under said means in which event said means is operable for dumping the dirt or matter into the Wagon or receptacle, the machine being readily restored for a new operation.

Another object of the invention is the provision of a loading machine having means which assumes a relatively iiat or prostrate position when lowered, to receive the dirt or material, said means when raised being operable to provide a hopper for convcniently dumping the material into the Wagon or receptacle.

It is also the object of the invention to provide a loading machine of the nature in dicated possessing novel features to enhance the utility and elliciency thereof.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts, and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made Within the scope of \th at is claimed, Without departing from the spirit of the invention.

'1. he invention is illustrated in the accompanying drawings, wherein 1- Figure 1 a plan view of the machine.

Fig. 2 is a side elevation thereof, partly in section on the line 2-:2 of Fig. 1.

Fig. 3 is a cross section taken on the line 3--3 of Fig. 1, illustrating the dirt holding means in raised position.

Fig. l is a fragmental end View illustrating the dirt holding means raised and operated to provide the hopper.

Fig. 5 is a horizontal section taken on the line of Fig.

The machine embodies a suitable frame preferably constructed of angle iron or other structural material, and including the parallel longitudinal base members or beams 1, the corner standards 2 secured to the ends of the beams, and the rectangular top memher 2; carried by the standards. Channelshaped guides are secured to the beams 1 and member 3 at the sides of the frame adjacent to the ends thereof, and the ends of the frame are preferably braced by crossed braces 5. The frame is of arch form, in order that wagons or other receptacles can be moved longitudinally thereunder, in one end and out the other. When the machine is to be moved from one place to another, this can be readily accomplished by securing the beams 1 on suitable trucks 6, but the use of these trucks is optional.

The dirt or material holding means is movable vertically within the frame, and embodies an open rectangular frame member or carrier 6 constructed of gas piping or other suitable material. 'lransierse supporting bars 7 re disposed umlerneath the carrier 6 and their ends are slidable in the re spectlve guides l. Upstanding rods 8 are secured to the bars T and are slidable through the longitudinal portions of the carrier 6. Cables or flexible elements 9 are attached to the bars 7 adjacent to their ends and extend upwardly Within the guides 4 and are passed oi'cr pulleys or guides 10 mounted for rotation. within the guides adjacent to their upper ends. From the pulleys 10, the cables 9 extend to and are secured to drums 11 mounted upon a longitudinal shaft 12 journaled in end bearings 12 carried by the top member 3, whereby when the shaft 12 is rotated in one direction, all of the ables 9 are Wound upon the drums for raising the bars '7, and when the shaft is rotated in the other direction, all of the cables 9 will be unwound to permit the bars 7 and carrier 6 to gravitate. As a means for rotat ng the shaft 12 to Wind up the cables 9, a drum 13 larger than the drums 11 is secured upon the shaft 12 and a cable or flexible element 11 is attached to and Wound upon the drum 1%. This cable 1i extends over and downwardly from a pulley 15 mounted upon the member 3 at one side, and said cable then extends under a pulley 16 carried by the frame adjacent to the base thereof. The cable ll can have draftanimals hitched thereto to thereby provide a haul line which can be pulled tor unwinding the cable from the drurn'li to thereby rotate the shaft 12 for winding the cables 9 upon the drums 11, or the cable ll can be pulled by a winch, Windlass, or other suitable mechanism, whereby to raise the dirt or material. holding means when loaded.

The dirt holding ineans also embodies side plates 17 projecting inwardly. and having bearings 18 secured thereto adjacent to their remote edges, and said bearings rotatably embrace the longitudinal portions of the carrier 6. The remote edges of the plates 17 have upturned flanges 19, and are also provided with notches 19 for accommodating the rods 8. The adjacent edges of the plates 17' have down turned flanges 1'20 terini' hating short of the ends of the plates 17. End plates 21 are provided between their ends with lower bearings 22 rotatably einbracing the end portions of the carrier 6, whereby the plates 21 as well as the plates 17 are swingable upwardly and downwardly. The end portions of the plates 17 have resting thereon the inner tapered wings of the plates 21, and the edges of the plates 21 are out obliquely, the adjacent edges of the plates 1? being provided. adjacent to the ends thereof with upwardly curved lips 23 to ride slidably upon the bars 7 The inner and outer wings or" the plates 21 are preferably at a large obtuse angle relatively to one another, whereby when the plates are in lowered position, the outer wings of the plates 21 provide runways for the devices for dumping the material onto the plates. Cleats 21 are secured on. the plates 21. to

V aid in dumping said devices. When the bars 7 and carrier 6 have gravitated, the inner wings of the plates 21 in resting upon the plates 1.7 are brought to a substantially horizontal position, and the plates 21 in resting upon the inner wings oi? the plates 17 are also brought to a substantially horizontal position. The dirt holding means moves into a relatively flat position when it is prostrate in its lowered position, for recei 7 and holding the dirt or other material. lVhen the carrier 6 is raised with he bars 7, said bars support the plates 17 which in turn support the plates 21, thereby preventing the plates troin. swinging downwardly with the carrier 6.

Means are provided for supporth'ig the carrier 6 when it is raised, in order that when the bars 7 are then lowered, this will enable the plates to swing downwardly to provide a hopper. Thus, upwardly projecting latches 24 are provided at the outer sides oi. the guides 4-, and are seated loosely in notched members 25 secured to the outer sides ot the guides, whereby the latches can swing to and from the guidesrwith their free ends projecting upwardly. The latches are each provided with a pair of flanges or wings 26 overlapping the respective guide 4- and providing a seat for the carrier 6, said flanges-projecting inwardly from the guide, as seen in Figs. 3 and 4:. Outstanding pins carried by the guides l project loosely t rough the latches 24, and springs 28 upon said pins press the latches toward the guides. The edges of the flanges 26 are inclined, whereby as the carrier 6 is raised, it moves past the latches and presses thelatches outwardly, and when the carrier is moved above the flanges 26, the latches are snapped in wardly under the influence of the springs 28 to engage under the carrier, and thereby support it in raised position. The bars 7 are movable between the flanges 26 and do not engage therewith, so that said bars can be lowered while the carrier is held in raised position, thus permitting the plates 17 and :31. to swing downwardly within the carrier 6.

In order to simultaneously release all of the latches from the carrier 6, longitudinal rock shatts 29 are disposed at opposite sides of the frame, and are journaled in bearings 30 secured to the standards or posts 2, and said shafts are provided with cranks 31 engaging behind the upper terminals or the latches 24-. The cranks 31 are normally swung against the guides 4: by the latches, and when the shafts 29 are swung in the proper direction, the c anlrs 31 are mover away from the guides whereby to retract the latches from the carrier, to enable the can rier to be lowered. Each shaft 29 is pro video at one end of the trains with an arm 32, and said arms are connected by liults with an oscillatory disk or lever mounted loosely upon one end'ol the shaiit 1'2. cable or flexible element connected with the lever 3-1: is slidable through a guide carried by the frame, and said cable can be extended. to a si" ible point to be pulled whereby to swing the lever 3st for pulling the links and swinging the arms to ward one another, thereby moving the cranks 31 outwardly to retract the latches.

In operation, when the dirt holding means is in lowered position, the bars '7 rest upon the ground. or underlying surface, and the carrier 6. rests upon the end portions of said. bars, the inner wings oil the plates 2i also if 11g upon the plates 17 and the plates 17 Jig upon the bars 7, whereby the plates are in a substantially horizontal plane iinniediately adjacent to the ground or undcrlying surface. The dirt or other material then shoveled or dumped onto the plates,

Fill

which can be done conveniently, and when the plates are tilled, the dirt holding means is elevated. This is accomplished by pulling cable l t by the use of draltanimals,a windlass, or other suitable means, whereby to unwind the cable 141: from the drum 13 and to wind the cables 9 upon the drums 11. This will raise the bars 7 which will elevate the :arrier t3 and its plates also. i l hen the carrier moves past the latches 52ml they snap under the carrier, and the cable 1 L is then .-=lacl ened, which permits the bars 7 to gravitate. tjlaid bars 7 can gravitate until the stops 'l'i' at the upper ends of the rods 8 contact with the carrier 6. Due to the tact that the bars 7 are lowered away from the carrier, this enables the plates 17 to swing lown'n'arrlly under the weight of the 1na lerial, the inner wings of the plates 21 also swinging llownwardly between the plates 17 as seen in Fig. l. The downward movement oil the inner wings of the plates 21 is limited by the plates 1'7 and the downward increment of the plates 17 limited by the bars The plates and it? in being swung ilewnwanlly will provide a hopper, the lates 2'1 titling between the plates 17 and the latter separating to provide a discharge opening, and due to the inclination of the plates, the material will gravitate down through the opening provided into the wagon or other receptacle which is moved nude;- the. carrii-u atter it was raised. When the plate. are swung downwardly, the plates ll will lit snugly between the plates 17, and there tore prevent leakage past the side edges oi the plates 21, thereby confining the dis charge ot-material to the opening defined by the free edges ol the plates. llhe material is thus readily raised and dumped into the wagon or receptacle. Then, after the wag-en or receptacle is moved out from undiathe :lrame, the apparatus is restored. This is accomplished by again pulling the cable let to in" e the bars 7, which will swing the inner wings of the plates :21 upwardly with the plates 1.? within the carrier. The carrier is raised slightly from the latches, and the ca le 35 is then pulled whereby to re ract the latches, after which the cable lat is lackened, allowing the carrier 6 and corresponding parts ol' the dirt holding means to gravitate to lowered position for again iweiving the material.

in view of the .lorcgoing, taken in connection with the drawin the advantages and attributes oi" the n'csent invention will no doubt be apparent to those familiar with the art, without further description being necessary.

Having thus described the invention, what is claimed as new is 1. A loading machine embodying a carrier, means extending below the carrier for raising it, means for supporting the carrier when raised, and pairs of plates hinged lo the carrier and projecting therein, one pair oi plates being slidably supported on said first mentioned means, the other pair of plates having oblique edges to rest slidably and snugly upon the first mentioned pair of plates to be raised and lowered therewith and to form a hopper when lowcred, the second mentioned pair of plates titling snugly between the first mentioned plates when the plates are lowered to prevent leakage past said edges 01' the second mentioned plates.

'2. A loading machine embodying a car ricr, bars extending underneath the carrier, means for raising said bars to raise the carrier, means for supporting the carrier when raised, said bars having upstanding rods slid-ably engaging the carrier to limit the downward movement of the bars away from the iarrier, and pairs of plates hinged to the carrier and extending therein, one pair o-rf plates having their inner ends slidable upon said bars to be raised and lowered therewith relatively to the carrier, the plates of the other pair having oblique edges slidable upon the plates of the aforesaid pair to be raised and lowered therewith and to form a hopper when lowered.

3. A loading machine embodying a frame having vertical channel-shaped guides, a carrier movable vertically within the frame, plates hingedly connected with the carrier to swing upwardly therein, bars below the carrier having their ends fitting slidably in said guides, means for raising said bars, latches carried by said guides for engaging the carrier to hold it in raised position, and upstanding rods carried by said bars slidably engaging the carrier.

t. A loading machine embodying a frame having vertical channel-shaped guides, a carrier movable vertically within the frame, plates hinged to the carrier and swing-able upwardly therein, bars under the carrier having their ends slid-able within said guides, means movable within said guides for raising said bars, and latches pivoted to the outer sides oi? said guides and each having opposite wings overlapping the sides of the guide and projecting inwardly therefrom to engage under the carrier, said bars being movable between. the wings of the latches.

5. A loading machine embodying a carrier. means extending below the carrier for raising it, means for supporting the carrier when raised, means for limiting the downward movement of the first mentioned means train the carrier when the carrier is supported, and a plurality of plates hinged to the carrier and projecting therein, said plates bearing together slidably and some of them having oblique edges to fit between fin-pies a! 1mm yeizem'; may he ebwined fm- 7 said plates.
