DUMPING-HQPPER VEHICLE.

To all whom it may concern:

Be it known that I, ALBERT'P. LEE, a

citizen of the United States, residing at position when loaded.

My invention relates more particularly to hoppers of the kind which are adapted substantially automatically to roll from a charge carrying to a discharge position, the preferred form of course contemplating this rolling action to both sides'of the central position.

In accordance with my invention I utilize a hopper of these. general characteristics, and in the specific illustration used herein I have taken the hopper shown in co-pending application Serial No. 142,419, filed Jan. 15, 1917. In hoppers of this character it has been found that the curvature of the hopper body, or in fact the whole general outline of the hopper body must be maintained in order to have proper cooperation between the hopper and the rail on which it rolls. 1 To this end my invention concerns itself with the specific hopper construction which I will now describe in detail in connection with the accompanying drawings illustrating the same,

in which Figure 1 1s an-end view of a vehlcle' constructed in accordance with my invention;

Fig. 2 is a fragmentary sectional view on line 2-2 of Fig. 1;

Fig. 3 is a sectional view along line 3-3 of Fig. 2 looking toward the left;

Fig. 4 is a sectional viewalong line 3-3 of Fig. 2 looking toward the right; a Fig. 5 is a transverse sectional View of the hopper and'rail;

Fig., 6 is a modified form of. the structure shown in Fig; 5, and

Fig. 7 is a detail of construction. Referring more particularly to Figsl,

per 18 and on which said hopper rolls. 'The hopper itself, as more clearly apparent from Figs. 1, 2, 3, 5 and Thas the channels 14, wh ch are adapted to cooperate with the rail 12. These channels are provided with holes 15 adapted to cooperate with lugs 16 projecting from the rail 12 so as to keep the hopper in its proper position vrelative to the rails. Across the bottom portion of the channels a tension element "l'i'yshown more clearly in Fig. 7 is providcd ,*-which= tension element through the agency: of 'its arms 18 1s securely riveted at its -meeting "point with the channel 14 by the rivets '19.

This tension element 17 thus prevents flattening of the lower curved portion 20 of the channel 14; By reason of the addition of this tension element the hopper is thus maintained in its original configuration or outline.- Tlie hopper structure is then completed through the addition of the'sheet .metal portion 21 which forms the floor and sides of the hopper, and which is of course of substantial thickness. The hopper is thus made up of this box structure .21 together with the channels 14 and the tension elements 17, there being of course as many channel elements 14 as there are rails 12, there being usually at least two rails [per hopper. The rails 12 are supported at their extremities by the arms 22' and these rails likewise carry the locking brackets 23.

In Fig. 6, I show a modified formof the structure shown in Figs. 1,2,3, 5 and 7 in that the sheet metal body portion 21 of the hoppemextends along the entire length of the channel 14. A. tension element 17 is provided which is riveted to the hopper as shown by the bolts 24 and thus serves its purpose of preventing flattening of'the hopper bottom. These tension elements 17 i may of course be used-for the additional purpose of a support for a false bottom indicated by the boards 25. The boards 25 of course may be omitted at times so. that the entire hopper maybe filled with vmaterial, Which' it is desired to convey.

In order to lock the hopper in its central position I provide a bolt 26 carried upon a stem 27, which stem is mounted in the lugs 28 and "29 carried at theentremity of the hopper. A spring 30 tends to press the stem 27 together with its bolt 26 downwardly through the agency ofi the collar .31 proa the other of the-links moves its c'otiperat:

co said railwhereby said hopper is adapted to vided upon the'stem 27 The stem is :preferably square-where it passes through the lug 29 so as to prevent rotation thereof. This ,bolt cooperates with the recess or notch 32 provided in the block .33 carried by the framework 34. \Vhen the bolt' is in its position by the block 36. This pin 35' has fingers37, 38 adapted to cooperate respectively with slotted links 39 and 40. These slotted links are carried at extremities of arms 41, 42, carried by the shaft 43. This .shaft is rotated through the agency of the handle 44. v

Now whenever the handle 44 is rotated to either side of its central position one or ing pin 37V or 38 upwardly, thereby moving the pin'35 upwardly until its top surface projects above the top of the plate 45,

immediately subsequently to which the bolt 26 passes out of the recess 32, whereupon the hopper may roll to its discharge position. It will beunderstood of course" that as soon as the top surface of the pin 35 proects above the top surface of the plate 45 that thenthe stem27 isthen no longer confined by the plate 45, the bolt 26 having been released, the hopper may roll to the side desiredi when the hopper is rolled back to .its central posltion the bolt 26 ride-s over one or the other-of thecam surfacefl 46 or 47 until it alines, With the recess 82 and snaps into position due to the agency of the spring 30 to thereby hold the hopper in its central position. It will be apparent that a rotation to either side of the central position of the handle 44 will occasion'a release of the hopper fromits locked position. When the stem 27 moves downwardly .upon the alinement of the bolt 26 and recess 32 it pushes the pin- 35 downwardly, which thereupon rotates the shaft 43 into its central position with the handle 44 standing vertical.

From what. has been thus described the" nature of my invention will be readily apparent to thoseskilled in the art.

Having however .thusdescribed my invention, what I claim as new and desire to secure by Letters Patent is:

Ina device of the character described the combination with arail, of a hopper adapted to roll on said rail from a charge c arryingto a discharge position, said hopper having arounded bottom to cooperate with roll substantially automatically upon said rail, and a tension element o1n1ng the exdiseases placed in said hopper, the space below the tension element forming part of the interior of the hopper.
