nun-earn.

Be it known that I, ALFRED W. KNUTSON, a citizen of the United States, residing at Galesburg, inthe countyof Knox and State of Illinois, have'invented certain new and useful Improvements in End-Gates; and I do hereby declare that the following is a full, clear, and exact description of. the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to end gates for wagons-particularly, however, to that type which closes the end of the wagon andwhich has an opening covered by a panel or closure and movable withrespect to it.

The main object of the invention is to provide an end gate ofthis description having an opening extending below the upper surface of the bed of the wagon body and not covered by any parts that would interfere with the free passage of materials from the wagon 'body, or such as would interfere with shoveling operations, there being a guide or' guides upon the end gate at said opening to' receive and guide the panel or closure at its lower extremity, said guides maintaining the panel in its proper position.

Another object is to provide an end gate or shoveling board adapted to be brought down to the open shoveling position, including an opening; for the reception of a panel or' closure, which, in the closed or vertical. position of the gate, is adapted for exposing said opening to any desired extent for the discharge of material without swinging from its position at said opening.

Another object is the-construction of a wagon body and end gate whereby materials that maylodge on parts of its rear end and that might prevent the proper seating of the panel can be readily discharged.

Besides the above objects the invention relates to other certain details of construction which will be more particularly pointed out in the following specification, aided by the accompanying drawings, in which,

Figure 1 is an elevation of the outer surface of the end gate or shoveling board; Fig. 2 is a longitudinal section of a portion of the wagon body, and the end gate or shoveling board, the latter being shown in its open'position;

position, together with the panel portion shown in an open position at right angles to the plane of said end gate;

Fig. l is a section of a part of the board and wagon body on line H, Fig. 1, the parts being much enlarged over that in Fig. 1;

Fig. 5 shows, in perspective, one of the parts of my structure;

Fig. 6 is an elevation of certain guide members and the parts to which they are se cured;

Fig. '7 shows the edge of a portion of the shoveling board and a pivoted guide thereon for carrying the panel;

Fig. 8 shows the same, in perspective, on a larger scale;

Fig. 9 is a slight modification of that form shown in Figs. 7 and 8;

Figs. 10 and 11 are details of certain pivoted members shown in Figs. 7 8 and 9;

Fig. 12 is an elevation of the outer side of a modified form of an end gate from that shown in Fig. 1;

Fig. 13 is a sectional elevation of the same on line 13-13 of Fig. 12;

Fig. 14 is a view of the inner or opposite side of the board from that shown in Fig. 12;

Fig. 15 shows, in perspective, the form of the device shown in Fig. 12 in the open position of the panel; and,

Fig. 16 shows, in perspective, the construction of certain detached parts.

In the first eleven figures 1 indicates the sides of the wagon body, 2 the bottom or bed thereof, 3 any usual sill beneath the bot tom or bed as its rear edge, and a an additional member bolted thereto as clearly shown in" Fig. 4, there being a series of openings 5 in the latter throughout its length shown partially in Fig. 16, the purpose of which will be disclosed later.

I do not claim broadly the relation of the movable closure or panel in an end gate but the combinations with certain structures that yield advantages to be named herein.

Fig. 3 thereby giving a clear working space upon the bed between the portions 6 so that materials within the'wagon box may be easily and readily discharged and also that the shoveling operation willnot be interfered wlth as stated earlier herein, there being no parts extending. across such opening.

9 indicates an ear secured to each side of the body 1, see Fig. 2, wherem but one 1s shown, and 10 are rods loosely attached at one end to each. 11, ll are keepers secured to the portions 6 through which the ears 8 purpose in practice. 12 indicates a block secured to each portion 6 upon each of which is secured a plate 13 each having a free edge extending-in the direction of the other, the plates at said edges being spaced from the portions 6 as clearly shown in Figs. 8 and 1, but said edges do not extend opposite the opening. This is clearly shown in Fig. 1. The lower ends of the plates are bent inwardly at right angles at 14 and secured to them in any desired manner is an angle bar 15, see Fig. 4. The ends of the angle bar are secured to the portions 6 in any approved manner, bolts 16, for, example, as shown in Fig. 4. This angle bar and the cross member 8 previously described serve to create a rigid frame structure with the portions 6. Y

17, 17 aremembe-rs secured to said portions 6, each being slotted as shown in Fig. 5, at 18, to receive the edge of the plates 13 into them, but this, it must be understood, is merely a preferred structure.

19, 19 are keepers secured to the members 17, for example, behind which the rods 10 are locked tomaintain the end gate in its closed position as in common practice. The relation of the angle bar 15to the bottom or bed of the wagon body is such as to leave a space between the end of said bed and said angle bar within the opening between the portions 6 to receive the closure now to be described. This comprises a panel 20 adapted to lie within the opening of the end gate flush with the latter, suitably cross-braced by an upper and a lower angle bar .21, for example, and secured to the portions 6 near each edge and near their upper ends is an angle plate 22 shown in detail in Figs. 10 and 11, and pivoted thereto is an angle guide-plate 23, forming a support and guide for said panel.

From the fact that the angle guide-plates 23 are pivoted as described, the said panel may be swung to any desired position and,

' of as shown in Figs. 8, 7 8' and 9. The cross member 8 limits the tilting of the panel and supports it in the position shown in Fig. 3,

when said panel is drawn far enough inward into the wagon box. When in the vertical position or in the same plane with the end gate the lower end of the panel lies between the angle bar 15 and-theend ofthe wagon bed 2. The space between the angle bar and said bed is just'? sufiicientto easily receive said paneland yet provide a tight closure so that there can be no leakage of grain. ,When it is desired to permit the flow of material from the wagon body byligravit'y' the panel may .be raised to any. desired extent but the weight of the grain cannot force the panel outward at its bottom'since ret ained by the guides 13. Theendsof the lower angle bar 21 on the panel project beyond the edges of said panel and engage behind the guides as clearly shown in said Fig.

.1, it being'understood that the edges of the panel lie close to'the edges of the portions 6 sothat there can be no leakage. of grain. The angle plates 22-are 'let into a recess 23' in the edge of the said portions 6 and the recess is deep-enough, also, to receive the outerlimb of the guide-plates 23 so that the edges of the said panel when closedwill fit closely against'the edges of said portions6.

' The openings 5' in the -member4 permit the material,-which would otherwise lie in therecess behind'the angle bar 15, tobe discharged therethrough so. as to permit" the panel to properly seat. When the end gate, including the panel,;is to be swung to the open position, Fig. Q'theangdebar 15itilts upon the member 4 naturally sliding forwardly thereon as the combined weight of the parts carries it toward the end of the wagon box. f 7

It is to be understood that while the arrangement described is the preferred one,

equivalents .may be adopted with regard to any of the parts of the entire structure, it being my desire to provide in a combined end gate and closure means at the bottom of said end gate to permit the vertical adjust ment of the panel for governing the rate of discharge prior to throwing the end gate down to the open or shoveling position while retaining the panel in the same plane with said end gate.

In Figs. 12 to 15 inclusive .1 have shown a simple form of device whichv is suitable for certain purposes. I

25 indicates the side portions of the end gate and 26 the panel pivotally mounted as before by means of the plates27 and 28 corresponding to 22 and 23 respectively of the toms orthe portions 25 which together with the membersO which correspondto 8' of the other figures, forms a complete rigid frame for said end gate; r

The bottom of the panelv engages behind said member29 lyingbetween itand the bottom or bed 31 of the wagon body. S'aid cross member 29 iss'paced above thebottom as clearly shown in 'Fig."15,.so that grain may pass out from beneath it when the panel is raised while still engaging behind said cross member.

The operation in this form is substan tially like that described as to the other figures.

Having thus described my invention, I claim 1. An end gate including in its construction a pair of portions adapted to be detachably secured to a wagon box, cross members connecting them near their opposite ends in rigid spaced relation, creating an opening between them, a guide secured to the lower extremity of each portion near its edge adjacent the opening, and secured also to the lower cross member, said lower cross member being spaced from the end of the bed of the wagon box, and a closure for the opening lying between the spaced portions adapted to engage between said lower cross member and said bed.

2. An end gate including in its construction two portions, cross members secured to both of them connecting them at opposite ends in rigid spaced relation, the lower of said members extending the entire width of the wagon box and lying rearward of and spaced from the bed of said wagon box, and a guide secured to each portion near its lower extremitv, said closure engaging the guides and adapted at its lower edge to drop between the end of the bed'and said lower cross member.

3. In combination, a wagon body having a member extending across its rear end below the bed thereof, said member having an opening extending vertically through it for the discharge of materials, an end gate adapted for attachment to said body including an opening, a member extending across the end gate across the last named opening spaced from the said bed and adapted to rest upon the first said member rearward of the described opening thereof, and a closure for the opening in said end gate adapted to seat between the said first member and the bed find overlying the opening in said first mem- 4. In a device of the class described, the combination with a pair of spaced members adapted to be detachably secured to a wagon box, cross members near opposite ends spacing them in rigid relation, one of said cross members being spaced from the end of the bed of the wagon body, and a closure for end below the upper surface of the the opening between the members adapted to enga e behind said mm ber between it and said waig'on bed, and able in its own plan an the plane ct the spaced members, across extending rearwardly from the we; bed below its upper surface up'on whic the lower'cross membe is; adafted to the "said member een ingthe rear of the wagon body having a series of holes for the escape of grain lodging between the wagon bed and the first named cross member.

5. In combination with a wagon body having a cross member secured at its rear bed of said body, an end gate including in its construction a portion adapted to lie against the rear extremity of each side of the wagon body, a member connecting the portions near their bottoms in rigid spaced relation leaving a space between such portions, said member lying opposite and being spaced from the end of the bottom of the wagon body opposite said space and extending the full width of said space, a guide secured to each of said portions perpendicularly to the plane of said bottom of said wagon body and secured to said member, and a closure slidable vertically between the portions adapted to seat upon the cross member between the said bottom and said member.

6. An end gate including in its construction a pair of spaced portions each adapted to lie against the extremity of one of the sides of a wagon box, a member attached to the rear sides thereof near their lower ends rearward of and spaced from the bed of the wagon box securing the portions in rigid spaced relation, and a closure slidable betweenthe portions adapted and arranged to lie forward of said member snugly between it and the end of said bed.

7. The combination with an end gate including in its construction a pair of portions to lie against the end of the wagon box, a cross member at their uper ends con necting them in rigid spaced relation, creating an opening between them, and a closure slidable between the portions arranged to have a pivotal movement with respect to the portions, within said opening, of a second cross member attached to and also connecting the lower ends of the portions in rigid spaced relation, the same lying rearward of them in rigid spaced relation, creating an opening between them, and a closure slidable between the portions arranged to have e piyotal movement with respect to the p0r-' tions within saidopening, of asecondcro ss memoer, attachedto an d also connecting the portionsjat theirlower ends in rigid spaced 5 relation, the :same lying rearward of the 'bed of the .Wagon box'and spacedtherefrom; i the closure adapted to seat snugly between thesaid second cross member'and the said end of the bed, a guide secured to M.
