BOTTOM-DUMPING WAGON.

Specification of Letters Patent. Application led August 31, 1907, Serial No. 390,935.

Patented July 11, 1911. Renewed April 23, 1909. Serial No. 491,851.

To all whom 'it' may concern:

Be it known that I, MARTIN L. SENDER- LING, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Bottom-Dumping lVagon, of which the following is a full, clear, and exact description.

he purpose of the invention is to provide a vehicle for carrying various kinds of material in bulk, and which is adapted to dump from beneath, and to provide what may be termed a dumping scow bottom, since the bottom, which is in two hinged sections opening sidewise in opposite directions, not only constitutes a bottom for the body but also has a carrying capacity of its own.

It is also a purpose of the invention to so construct the sections of the bottom that they will have individual maximum strength, and whereby, also, when the sections are dumped, they will occupy a position that will insure a speedy and clean delivery of the material not only from said sections but also from the body of the ve hicle, and wherein, as the sections of the bottom are brought to a closed position, a sealing Hap or strip carried by one section, will automatically enter the opposing section, bridging the joint, and as a close contact is also made between the sections of the bottom and the body when the bottom is closed, the said bottom section at such time is closed tight.

It is also a purpose of the invention to provide stirrups f or supporting the bottom sections in closed position instead of chains commonly employed for said purpose, and, further, to provide means for conveniently, quickly and to supporting position relative to the bottom, and for removing them from the bottom when a dump is to be made, which is very simple and readily operated.

Another purpose of the invention is to carry the body high above the axles, enabling the sections of the bottom to have great depth, and preventing their interference with the wheels while being' operated.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanypositively bringing the stirrups ing drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the vehicle, a portion of the body being broken away, and one axle being in section; Fig. 2 is an enlarged transverse section looking rearward, the bottom being closed, the section being taken on the line 2-2 of Fig. l; Fig. 3 is a rear end view drawn upon an enlarged scale, the bottom being also closed; Fig. et is an enlarged transverse section taken practically on the line 44 of Fig. 1, looking forward, the bottom being in dumping position; Fig. 5 is asection similar to that shown in Fig. 2, but illustrating a slightly modified form of mechanism for raising the bottom sections; Fig. G is a vertical section taken practically on the line 6*@ of Fig. 2; Fig. 7 is a horizontal section taken practically on the line 7*? of Fig. 2; and Fig. 8 is a horizontal section taken substantially on the line 8-8 of Fig. 5.

.The body of the vehicle consists of side pieces 10 that are generally inclined from the top downward in the direction of each other, and the carrying chamber or section A of the body is formed by placing a front board 11 and a rear board 12 between the side pieces 10, and securing them properly thereto. These front and rear boards inoline downward in the direction of each other, as is shown in Fig. 1. The side boards 10 extend quite a distance beyond the front board 11, as is shown at 10a in F i0. 1, while the said side boards 10 extend but a slight distance beyond the rear board 12, as is shown at 10b in Fig. 1; and it may be here remarked that the carrying chamber A only is provided with a bottom section.

The forward axle 13 is provided with a suitable running gear 14, and is pivotally located with regard to the front of the body, and the front portion of the body is held at quite an elevation above the forward running gear 14, by top blocking 15 by which the upper rim of the fifth wheel is mounted upon carriers 16. The rear axle 17 is also located some distance below the bottom of the body of the vehicle, and is connected with it, usually by means of pedestals 18 which form its support, and which are otherwise additionally secured to the side portions of the said body and having a bearing upon the axle, as shown in Fig. 1. That portion of the body in which the carrying chamber A is located is provided at its side portions with exterior straps 19, usually three in number, located one near each end of said chamber, and one near the center. These straps extend from top to bottom of the side pieces 10, as is best shown in Fig. 1, and terminate at their lower` ends in eyes or knuckles 20, which may be fully closed or partially closed, as desired; and the lower edges of the side portions of the body at the carrying chamber A are shown in Fig. 4 inclined from the outside downward and inward, but such inclination may be omitted,

' and at the lower portion of the carrying chamber A a sealing member 22 is located, which member is in the nature of a fixed sleeve or curtain. This sealing sleeve or curtain 22 is made of a flexible or yielding material, and is fitted to the inner contour of the said chamber A, as is best shown in Fig. if The sleeve 22 has the same downward inclination as has the upper wall of the chamber A, and projects some distance beyond the lower beveled edges 21, as is shown in Fig. t wher-e it is designed to project into the inner rabbeted edge 22a of the bottom when the bottom is closed. 1t may be here remarked that the knuckles or eyes 20 at the ends of the straps 19 are carried somewhat inward along the inclined side surfaces 21. The eyes or knuckles 20 which are at both sides of the body chamber A are adapted to loosely receive shafts 23 which are pendant thereupon, and the shafts 23 extend the length of the chamber A, and at their ends are supported-in suitably located bearings 24, as shown in Fig. 2. The shafts 23 carry t-he sections at the bottom of the said chamber A, by means of suitable strap bearings as shown by 31, 33 and 34- in Fig. 4L, and at 31 in Fig. 1, which sections are two in number and are designated respectively as B and B, as is best shown in Fig. L1. The sections B and B are practically of the same formation and are very deep, being what I term scow s-ections or bottoms, since they contain considerable material and add materially to the cubic contents of the body of the vehicle. When the scow bottoms or sections are in closed position, their upper edges are practically on a line with the central line of the shafts 23, which insures a free drop of the sections to dump the load. It is also to be noted that the chief function of the shafts 23 is to prevent transverse twisting of the sections in operating them.

Each bottom section consists of end boards 25 of suitable thickness, an outer side board 2G that is preferably given a downward and an inward inclination, and a bottom board 27 tightly secured in any suitable or approved manner to the end boards 25 and the side board 26. The end boards 25 of the bottom sections correspond to the end boards or walls 11 and 12 of the body chamber. In the further construction of a bottom section, a central partition 28 is provided, which is of less height than the height of the side and end walls of the section, as shown in Fig. 4t. These partit-ions serve as additional supports for the bottom sections and give them such rigidity that they can be bodily operated from one end; and at the bottom of each section at its inner e'dge, a sill 29 is firmly secured, and the lower face portions of the sills are beveled or rounded off, as is shown at 30 in Figs. 1 and 2, to permit the ready passage of supporting stirrups beneath them, which stirrups will be hereinafter described.

1V hen the sections B and B of the bottom are closed tightly against the body, the sills 29 are brought close together, as is shown in Fig. 2, and when the said sections are so closed, the sealing sleeve 22 effectually prevents any material from entering the space between the inclined lower edges of the body and the mating or engaging edges of the said bottom sections, and also when the bottom sections are open or brought to dumping position as is shown in Fig. 4. The arrangement of the means by which the joints between the upper and lower portion of the body of the wagon are sealed against leakage is such that there is no point for lodginent of the material conveyed, by which the sealing device can become clogged and thereby lose its efiiciency.

The straps 31 are attached to the bottom sections B, B', and are located centrally and at opposite ends of the sections as is shown in Fig. 1, and the straps 31 are provided with eyes or knuckles 32 at the upper edges of the side boards 26 that receive theV said shafts 23, as is illustrated particularly in Fig. et, and these knuckles or eyes 32 are usually keyed or otherwise fastened to the shafts 23. The end straps are usually carried along the upper edge of the end members 25 of the bottom sections B and B to strengthen them, as is shown at 33 in Fig. 4t, and the central straps 31 are continued from their knuckles down along the outer faces of the side members 26 of the sections, and along the upper edges of the partitions 2S, as shown at 34 in Fig. A, strengthening the latter and giving a maximum of strength to each completed section; kand it may be here remarked that the sills 29 extend beyond the ends of the sections B and Bl a desired distance, for a purpose to be stated, and that the straps 31 are continued along the bottom of the sections and are carried and secured to the bottom portions of the aforesaid sills 29, as is shown in Figs. 2 and 4. A sealing strip 34C@L is attached to the-end members 25 at the open portion of the section B, for example, which sealing strip projects beyond the said open edge of the section B, and at the bottom of the same sec tion sealing flaps 35 are pivoted or hinged at their inner edges so that their opposite edges are free, which latter side portions extend out beyond the inner open edge portion of the section proportionately to the projecting' parts of the sealing strip 34a; and the opposing section B is provided in its bottom portion at its open edge, with a recess 37, that is adapted to receive the projecting edge of the sealing Hap 35 when the sections B and B are closed, so as to cover or bridge the joint between the sections and prevent the escape of material, and at the same time the sealing strip 34a enters the section B and engages with the inner faces of its side members for the same purpose.

With reference to the means for holding the sections of the bottom located in closed position, and releasing them to permit their assuming a dumping position, such construction is as follows: At the front face of the forward end board l1 of the chamber A, a central strap 38 is secured, and a second strap 38a to the left of the strap 38, as is shown in Fig. 2. These straps have knuckles formed at their lower ends, which knuckles are at the lower edge portion of the board ll, and form bearings for a shaft C, which shaft is illustrated as extended out beyond the left-hand side of the vehicle, but may extend beyond the right-hand side of the same. The shaft C has secured to it the, members of a stirrup D, the members being located at the opposite sides of the central strap 38, and the stirrup D is of sufficient length, when the bottom sections are closed, to fit over the forward projecting ends of @-0 the bottom sills 29. Collars 40 are secured to the shaft C at opposite sides of the bearing 38, and between the bearing afforded by the strap 38a and the adjacent side wall of the vehicle. This shaft is provided with a lever 4l by which the shaft may be rocked.

At the outer end of t-he shaft C a downwardly extending crank arm 42 is secured, and at the rear'end of the vehicle a shaft C is located, parallel to the front shaft C. This shaft C is shown as extending the width of the vehicle, but it may be made shorter if so desired. The shaft C is mounted to turn in bearings 43 that are secured near to the bottom portion of the rear board l2 of the carrying chamber A, and at the outer end of this shaft- C that extends out beyond either side of the vehicle, an upwardly extending crank arm 44 is formed or is secured, and* the two crank arms 42 and 44 are connected by a link 45, the ends whereof are suitably formed, as is shown bestin Fig. l, and this link 45 is parallel with and adjacent to the left-hand shaft 23, as is also indicated in Fig. l. 55 The rear shaft C has secured to its central portion a stirrup D', and this stirrup D is of suiiicient length to ft over the rear ends of the bottom sills 29 when the bottom sections are closed, as indicated in Fig. 3. It will be observed that by reason of the connection described between the two shafts C and C', when the lever 4l is moved in one direction, the shafts will be rocked in oppoe. site directions, and at one time the tivo stirrups D and D will be simultaneously brought to a vertical position in engagement with the bottom sills 29, and when the lever 4l occupies another position, the said stirrups will be simultaneously carried outward and away from the sills 29, thus permitting 8o the sections of the bottom to drop downward to dumping position, as shown in Fig. 4. The form of both stirrups D and D is such as to permit of frictional bearings employed to more easily envelop the ends of the sills 29.

Vith reference to the mechanism for raising the sections B and B of the body from their lower to their upper position, this mechanism is shown in Figs. 2, 4,- 6 and 7. 90 A short shaft 46 is secured in a bearing 47 at the upper central outer portion of the front board ll, and upon a suitable bearing on a transverse beam 48 that extends from side to side of the vehicle in front of said front board ll as is shown in Fig. 7. A gear wheel 49 is loosely mounted on the said shaft 46,'and a crank 50 is made integral with this wheel 49 at its rear portion, and the, said crank 50 is provided with a longi- 100 tudinal slot 5l of suitable length. This slot 5l receives a pin 52 that is in the nature of a bolt, and the said bolt is attached to the upper end of what may be termed a retaining' link 53, which is provided about 105 centrally between its ends with a hook formation 54 adapted inone position, that is, when the bot-tom sections are closed, to occupy a position over and in engagement with the shaft 46, as is shown in dotted lines in Fig. 2 and in full lines in Fig. 6, and at such time the crank 50 is in an upper vertical position. The lower end of the retailiing link 53 is attached preferably to a horizontal equalizing bar 55. At suitable varying distance from each side of the center of the said bar, links 56 and 57 are pivotally attached to the ends of the equalizing bar and to the upper end portionsof straps 58 that are secured about centrally to the forward end port-ions of the bottom sections B and B; thus, when the retaining link 53 is carried upward to close the sections B and B of the bottom, one section moves slightly in advance of the other, so as to permit of their proper engagement in assuming their fully closed position.

The crank 50 is carried to its upper position by means of a shaft 59, which is journaled in suitable bearing's 60 on the for- 130 ward beam 48, as is shown best in Fig. 7, and this shaft is free to turn in its bearings, as are the gear 49 and crank 50 free to turn on the shaft 46. At the inner or rear end of the shaft- 59 a pinion 61 is secured, that meshes with the gear 49, and at the outer or forward end of the shaft 59 a hand wheel 62 is secured, having integral therewith orv attached thereto, a ratchet wheel 63 that. is engaged by a pawl 64 pivoted upon the front beam 48. Then the bottom sections are in their dumping position, the crank assunies the downward vertical position shown in dotted lines in Fig. 4. Then the sections are to be elevated, it is simply necessary to turn the hand wheel 62 until the sections have been closed, at which time the hook portion 54 of the retaining link 53 will have engaged with the shaft 46, as is shown in Figs. 2 and 6, and will serve to hold the said sections temporarily closed. Then the lever 4l is operated to bring the stirrups inward to supporting engagement with the end portions of the bottom sills 29. Vhen the sections are to be dumped, itl is iirst necessary to turn the hand wheel 62 a sufficient distance to rock the crank downward enough to cause the hook 54 to free itself from the shaft; that will probably be about the distance of a couple of teeth on Athe ratchet wheel 63, whereupon the lever 4l can be moved in an vopposite direction carrying the stirrups D outward, releasing the beams 29 and permitting the said sections B and B to fall downward as far as their links 56 and 57 I will permit. By bringing the hinged connection opposite to, or between the sections B and B- and somewhat within the line of the outer faces of the sides of the body, a far better support for the said bottom sections is obtained, space for swingw ing movement is increased, and a much better closure is effected when the said bottom sections are. closed.

In Fig. 5 I have illustrated a modified form of lifting mechanism, wherein a lift device is employed for each of the sections. but the two devices are operated by the same means. For example, two parallel shafts are provided. both of which extend from the forward face of the front board l1, the shafts being designated at 65 and 68; the shaft 65 being secured in a bracket 66 and terminates in a head 67. while the shaft 68- is secured in a bracket 68a. A gear wheel 69 is loosely mounted on the shaft 65, and the said gear wheel is provided with a crank 70 that extends therefrom` havinga slot 71 therein. This slot receives a pin 73 from a link 72 that is attached in any approved manner to a strap 75 secured to the forward end of the section B. The link 72 is provided between its ends with a hook formation 74, adapted, when the section is elevated, to engage theshaft 65. A gear 75a is mounted loosely upon the shaft 68, and said gear is provided with a forwardly eX- tending hub 76, upon which hub a hand wheel 77 is secured, and a crank 78 extends from the gear 7 5a, being provided with a slot 79 therein that receives a pin 8O from a link 81 pivotally attached to a. strap 82 secured to the forward end of the section B. Thus, by operating the hand wheel 77, both gears 75a and 69 are brought into action, and the sections can be simultaneously raised. Vhen the sections are to be dumped, however, it is necessary to first release the hooks, one of which, 83 is also provided for the link 81, from the shafts 65 and 68. This is done' by forming a projection 84 on the hub of the gear 69, and a similar projection 85 on the hub of the gear 7 5a, so that by turning the gears in one direction, these projections strike the hooks in the links and lift them up.

Having described in detail the mechanism which is embodied in the preferred form of my invention, I do not limit myself to those specic details except in so far as they or their equivalents are suggested in the following claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent,-
