SIDE-DUMPING BODY FOR VEHIOLESL.

SPECIFICATION vforming part of Letters Patent N o. 726,638, dated April 28, 1903.

Application iled August 27, 1902.

T0 a/ZZ whom, it may concern:

Beit known that LWILLIAM L. CHnssRowN, a citizen of the United States, and a resident of Eaton, in the county of Weld and State of Colorado, have invented a new and Improved Side-Dumping Body for Vehicles, of which the following is a full, clear, and exact description.

My invention relates to an improvement ink the body or rack construction of vehicles and the purpose of the invention is to provide a side dump wherein the dumping will be automaticall y accomplished the moment that sundry supports beneath the body or rack are Withdrawn, which Withdrawal at the dumping side of the body or rack is accomplished by a single movement of a single lever, and, further, to so construct the rack or body that as the rack or body is restored to its normal position the side gate opened for dumping will be automatically closed.

Another purpose of the invention is to provide a construction of a side-dumping body or rack which will be simple, durable, eco-l nomic, and practical, automatic, and capable of being used on any wagon-gear, which con-I struction of body or rack is especially adapted for hauling sugar-beets, but which may be adapted for all purposes of a farm and upon any vehicle wherein material istobe hauled and dumped, including railroad-cars.

The invention consists in the novel vconstruction and combination of thev several parts, as will be hereinafter fully setfort-h, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a 'side elevation of thevehicle body or rack having the improvementapplied, thecarrying-section being in normal position. Fig. 2 is an end view of thevehicle body or rack, the carrying-section being also shown in normal position. Fig. 3 is a sectional end elevation of the body or rack, showing the carrying-section in dumping position. Fig.

Fig. 6 is an enlarged side elevation of the lever-controlled means for operating the side gates of the carrying-section. Fig. 7 is a detail sectional view showing the application ofthe dumping-lever to a side gate of the carrying-section of the body or rack, the said section being practically onthe line 7 7 of Fig. 6. Fig. Sis a vertical section taken substantially on the line 8 A8 of Fig. 2, and Fig. 9 is a detail perspective View of one of the bearing-blocks for the carryingsection of the body or rack. 1

The device consists, primarily, of a basesection A and a carryingection B.. The basesection consists of pairs of longitudinal side beams 10, connected at their bottom portions at suitable intervals apart by cross-bars 11.. Transverse supporting-beams 12 are made to rest on the side beams 10, the transverse beams 12 being of any suitable dimensions,

and the side beams lO are attached to the bottom cross-bars 11 through the medium of rods 13 in the form of clips.

At the central portion of each transverse beam 12 a bearing-block 14 is supported, the said bearing-blocks being provided with longitudinal channels 15 in their under surfaces, so that the said bearing-blocks may straddle the transverse beams 12. Clips 16 are elnployed to hold the bearing-blocks on the transverse beams 12, the upper portions 17 of which clips are bifurcated, so that the upper portions of the clips may pass over the bearing-blocks at each side of their centers, as is shown in Figs. 2, 3, and 4. Each bearing-block 14 at its upper central lportion is provided with a trunnion 18, which trunnions extend in horizontal alinement from the side portions of the blocks, as is best shown in Fig. 9. l

In the spaces between the longitudinal side beamsA 10 of the base-section A supportingbars 19 are pivoted at their lower ends, as is best shown in Fig. 5. These su pporting-bars are adapted to assume the inclined position shown in Fig. 5 or the perpendicular position shown in Fig. 1. -The supporting bars or standards 19 at each side of the base-section A are connected by a link 20, and at one end of each link one end of a spring 21 is secured,and theopposite ends ofthe said springs are att-ached to either one or the other of the pair of longitudinal side beams 10. At the opposite end of each link 20 a lever 22 is pivotally attached, and the lower ends of these levers are suitably fulcru med upon projecting arms 23 from an end of the base-section A, as is illustrated in Figs. 1 and 5.

The carrying-section B of the body or rack may be of any suitable size, and consists of end sections 24, a bottom section 26, and side sections 25, which are hinged to the bottom section, as is shown in Figs. 3 and 4. These side sections 25 constitute side gates for the said carrying-section B, and when dropped down flush with the bottom 26 permit the contents of the carryingsection to pass out at the open side when the said carrying-section is inclined in direction of such side or is brought to thedumpingposition. (Illustrated in Figs. 3 and 4.)

Transverse beams 27 are arranged, preferably in pairs, at the under surface of the bottom 26, as is shown in Fig. 1, a pair of such transverse beams 27 being also at each end 'tween the said slats or plates and the end sections 24, in which chambers 29 pulleys 30 are mounted to turn, and the end sect-ions or plates 29 preferably extend down below the bottom 26 of the carrying-section, as is illustrated in the drawings.

At the central portion of each transverse beam 27 of the carrying-section B of the Vehicle body or rack a block 31 is secured, and these blocks are preferably slotted or have channels produced in their upper portions, whereby they may straddle the transverse beams 27, and each block 31 is provided with a suitable opening to receive a trunnion 18 of a bearing-block 14. Through this connection between the bearing-blocks 14 and the blocks 3l of the carrying-section the carrying-section is centrally and pivotally mounted upon the base-section A.

Suitable braces 32 are attached to the downwardly-projecting portions of'the plates or laths 28 and to the bottom 26 of the carryingsection. Side braces 33 are also employed, which side braces are attached to the bottom portion of the base-section A and are connected with the inner blocks 3l of the under set of blocks, as is shown in Fig. 1, turnbuckles 34 being located between the points of attachment with the base-section A and the attachment of said braces with the carrying-section, so that these braces need in no manner interfere with the dumping action of the carrying-section, yet add materiali)T to the strength of said carrying-section.

At each end of the carrying-section B of the vehicle body or rack two horizontal lengths of chain 35 and 35a are secured at one of their ends to the end portions of the side gates 25, as is best shown in Figs. 2 and 3, and the lengths of chain 35 and 35 at each end of said carrying-section are connected by a spring 36 of suitable strength, which springs serve to draw the side gates from their lower or dumping position to their upper or closed position and retain such side gates in such position when used in connection with elbowlevers 38 and 38, pivoted one at each side of the center at each end ofthe carrying-section, and the upright members of. the elbow-levers 38 and 38a normally engage with the outer surfaces ot' buttons 37, located on or formed integral with the lengths of chain 35 and 35, where they connect with lthe springs 36, the upper ends of the said elbow-levers 38 and 38a being downwardly and outwardly beveled.

Each elbow-lever 38 is pivotally connected with the upper end of a link 39, while the elbow-levers-38n are similarly connected with links 39a. These links at their lower portions cross each other at the ends of the body or rack and are pivotally attached to the end transverse beams 12 of the base-section A at each side of the center of such beams, as is shown also in Figs. 2 and 3.

When the carrying-section B of the body or rack is in its horizontal or normal position, (shown in Figs. 1 and 2,) itis supported in such position by means of the supporting-bars 19, which are thenw perpendicular, as is shown in Fig. 1, and are in engagement with the under faces of wear-plates 40, secured to the under surface of the bottom of the carrying-sections B, the said wear-plates being provided with suitable longitudinal guide-ribs 40, although these ribs may be omitted, if desired. When the load is to be dumped, the lever 22 at that side at which the dumping is to be accomplished is drawn downward, as is shown in Fig. 5, thus carrying the su pporting-bars 19 at said side to the inclined position, (shownin Fig. 5,) whereupon the weight of the material in the carrying-section B will tend toward the nnsupported side of the carrying-section, causing said side to assumeadownwardly-inclined position, (shown in Figs. 3 and 4,) and likewise cause one of the elbow-levers-the elbowlever 38a, for example, which is near the inclined sideto be carried away from the buttons 37, whereas the opposing elbow-levers 38 will be drawn in direction of the inclined side, whereby the elbow-levers 38a permit the springs 36 to extend, and consequently permit the side gate at the lower side of the carrying-section to drop, while the opposing elbow-levers 38 maintain their positions at the lugs or buttons 37, adjacent to the elevated side of the carrying-section, thus holding the side gate at that side closed. This movement of the elbow-levers is brought about by the movement of the links 39a incident to the inclined position of the carrying-section A.

After theload has been dumped the springs IIO sus

36 willagain contract to close the dropped side gate, and the carrying-section of the Vehicle body or rack being-simply pivoted will normally assume itshorizontal position, at which time the pivoted supporting-barslQ are again restored to their vertical positions. When the carrying-section B of the body orv rack is carried to its dumping position, it is held in such position until the dropped side gate is elevated by means of latches 41, which are pivoted in suitable bearings 42 at the unt der central portions of the carrying-section B, as when the carryingsection B is inclined the latch 4l at the inclined side will engage of the carrying-section B, one of the said posts being at each side of said section, and when the side gate at the lower portion of the carrying-section drops to a dumping position the head 44.0f theprojecting post 45 at that side of the carrying-section will extend over the pivot portion of the latch 4l; but as the side gate is brought to its upper position the head 44 from the post 45 in action will press upon the pivoted end of the latch 4l in actionand carry said latch out of engagement with its keeper 43, thereby permitting the carryingsection B to resume its horizontal or normal position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- Y l. A dumping carrying-sectio n,a base-section on which the carrying-section is p'ivotally mounted, side gates adaptedV to drop, and' means for automatically opening one side gate and holding the other side gate closed, which means are operated through the movement of the carrying-section upon the base-section, as
