END-GATE.

Application `filed December 26, 1919. Serial No. 347,293.

grain to escapeint'o an elevator, the device being arranged to permit Athe end-gate to open only the proper distance however much the forward end of the wagon box maybe elevated, and to hold it secured to the wagon box all the time whether in its opened or closed position, in order to prevent it from at any time becoming accidentally detached from the wagon box, sothat if a carelessA driver forgets to close the end-gate, he is in no danger of losing it as he drives home. Another object is,` to provide a device which gives an opening at the middle of the rear end; of the wagon borstA which opening causes the grain toenipty into the middle of the dump hole of the elevator, thereby preventing any of the grain from spilling out at thesides of said hole. Inthis latter respect ythe device is specially adapted for use with truck bodies which are wider than ordinarywagon bodies, and therefore spe cially liable to spill out grain at the sides of the dump hole, if provided with-the ordinary end-gate. A

Still another object is toprovide an endgate of 'this character which is normallyV held Hush with the rear end ofthe wagon box, so las to giverthe largest possible opening in proportion ,to the distance the hinged sections of the end-gate are moved rearwardly. i

Other objects will appear in the subjoined description.

An important feature ofthe invention consists of a pair of keepers rigidly securedl to the sides of the wagon box, and each having a head and neck portion projecting beyond the rear end of the wagon box; a pair of latches cooperating with said keepers, said,4 latches being each loosely pivoted at one end to the end-gateand provided at the other end with a longitudinal slot for receiving the neck of the keeper, said slot having an opening leading out through the lower side thereof, to permit the slot in the latch to engage the keeper g' andangle corner pieces at the rear corners of the wagon box for stops to hold the ends of the end-gate against rearward movement.

The invention consists in the novel construction and arrangement of the several parts, as will be hereinafter Vdescribed and claimed, reference being had to the aecompanying drawings, in which 'Y Figure l is a broken perspective view, showing an end-gate provided with my iin provenient.. Fig. 2 a top plan view of the rear portion of a wagon bei; provided with my improvement. Fig. 3 is a plan view of one of the keepers; and, Fig. la is a similar view of the pivoted latch cooperating there with. y y

'llhe numerals l and 2 indicate the bottom and sides respectively of a wagon box, which is provided with an end-gate formed in two sections 3 and dconneeted together by hinges 5. ri`he section 8 carries a latchboard 6 rigidly secured4 thereto, and the section l a rotatable latchV 7 ladapted to cooperate with the latch-board 6 by means of the slot 8 at the free end thereof, to lock the parts of the end-gate together in their normal posit-ion on the wagon boX.

rlhe wagon box is provided at its rear corners rwith angle irons 9 which are formed preferably of steel. The broader sections 9t of these angle irons are rigidly secured to the vsidesi 2 of the wagon box with the narrower sections 9b lapping the ends of said sides and projecting inwardly beyond the same. Y

et the rear inner corners of the wagon boX are the vertical cleats l0, rigidlysecured to the sides 2 of the boX and spaced from the rear ends of said sides a distance approximately equal to the thickness of the material used in making the sections 3 and 4 of the end-gate.

l/ihen the end-gate is in its normal closed position as illustrated in Fig, l of the drawings,l the free ends of its sections 3 and l are received between the cleats l0 and the sections 9b of the angle irons. That is to say, each section takes the place of one of Y on the bottom y from t e end thereof. ll

the free end ofthe latch-board 6 from the.V section e ofthe end-gate, and the endgate` the ordinary wooden cleats usually einV rangement holds the end-gate flush with the` rear end of the bottom 1 of the box, whereas with the ordinary arrangement, employing two wooden cleats, the end-gate is held about two inches inwardly For a dumping wagon, my present arrangement has the very decided advantage of giving the largest possible dump-opening when the'sections 3 and il; of theV end-gate are moved rearwardly a given distance. -lnaddition to this, wooden cleats when frequently subjected to sudden and heavy strains soon work-loose and become unre-f` liable, to say nothing ofthe fact that they are easily affected by moisture and will soon begin to rot when exposed to the weather.VV

In addition to the above, the angle irons 9 also coperate with important features, now to be described, in a way produce most desirable results, when the end-gate is broken for any reason either intentionalor accidental. i i

rlhe keepers 11 are rigidly sections 9a of the angle irons, and have their head and neck portions 11L and 11b respec- VY tively projecting rearwardly beyondV the angle irons.- rlhe corner latches 1Q which cooperate with these keepers 11 are provided at their inner ends with bores 13 and at their outer ends with longitudinal slots 1e having openings 15 leading out through their lower sides. By means of the bores 13 these corner latches are loosely pivoted to the sections 3 and 4 of the end-gate, and

the necks 11b of the keepers are adapted to' be received into the slots 14E through the" openings' 15. fit the inner ends of the corner latches I provide the washers 16, -and the free ends 12a of these latches may be curved outwardly if desired, as illustrated in Fig. 2, though they also work well'when perfectly straight.

ln operation, my end-gate vwhen in its closed position, as illustrated in lFig. 1, is

held in this position in lthe ordinary wayY by means of the latch 7, with'the" ends of the end-gate received between the .cleats 10 and the rear sections 9b of the corner angle irons. TWhen in this position, the' keepers 11 and the cooperating corner latches '12 are practically idle, though, of course, Vthey would preventY the end-gate Vfrom Vbeing moved upwardly if that were attempted. lt will beV noticed that the arrangement of the parts is such that the corner latches'12 cannot be disengaged from the keepers 11 tillthe latch 7 has been operated to release moved rearwardly sufficiently to bring the securedto the. sides 2 of the wagon box, preferably on the .Y p

f-between the cleats 10 and the sections 9b of y the angle irons, the lend-gate cannot rock lgrain into an elevator, and the rear' end of the wagon box has been brought overthe Aelevator hole, and thefront end of the box elevated, the endgate is then `unlatched by a proper turn of the latch 'githerearward pressure of the grainl will now` openv the end-gate bringing the parts into the position illustrated in` F ig. ,2, with-the widest point in the dumpopening exactly at the middle of the wagon box.AV The latches A12 will not permit theend gate to open only so A far, nomatterhow great the pressure of the grain against it, or how `suddenly it may have opened when the latch 7 was operated;

lilith ordinary endgat`es,-there is danger at this point of the end-gate' being jerked Vout of the hand ofthe operator, and carried down through the elevator hole with the ram. j Y f As the outer ends of my end-gate areheldup' and-'down at its middleportion but is held rigid, vas it were, l,against such move-1 ment, and always substantially` at right an#Y gles to the plane of the bottom of the wagon'y bozen 'l A My device` does not open the whole rear end of thegwagon'bombut only Va certain predetermined portion at the center thereof, so that .italways causes `the graintoruny into the middle of tlie'eleva'tor hole, and does not permit such a wide flow of grainV from the box as to scatter it at the sides of the hole where it would havejtobe swept in with a broomy after the' load had -loeenV dumped from the'wagon; llorv this reason, mydevice is specially adapted for use with truckbo'dies which are wider than 'wagon bodies. d Y 'A From the foregoing it will beVV seenv how greatlysuperior my'devic'e is to the ordinary endf-gate which has to be entirely removed from thewagon boX when grain is to be Vdumped into an elevator. e

Again attention is calledto the fact that the corner latches 12 cannot accidentally"vv become disengaged from the keepersfll when the end gate is brokenl el, open),

Aas illustrated in Fig; 2; and therefore if a rior merit and of great practical value, as have fully proved, having thoroughly tried ont the device in practical use.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is l. 1n a device of the character described, the combination with the sides and bottom of a wagon box, of an end-gate hinged between its ends to openk rearwardly; spaced cleats on the sides of the box for engaging the free ends of the end-gate sections to hold them against lateral movement while permitting them to move toward each other when the end-gate is opened rearwardly; rearwardly projecting keepers secured to the sides of the wagon box; corner latches pivoted at their inner ends to the hinged sections oi' the end-gate, and provided at their outer ends with means for engaging and disengaging said keepers, said means including longitudinal'slots in engagement with said keepers to permit longitudinal movement of the latches on the keepers for permitting the sections of the end-gate to move toward each other when opened rearwardly without becoming detached from the sides of the wagon box; and means for securing the end-gate sections in rigid relation to each other* 2. In a device of the character described, the combination with the sides and bottom of the wagon box, of an end-gate hinged between its ends to open rearwardly; spaced cleats on the sides of the box for engaging the free ends of the end-gate sections to hold them against lateral movement while permitting them to move toward each other as the end-gate is opened; rigid keepers projecting rearwardly 'from the sides of the wagon box with the projecting portions of said keepers having reduced neck portions; corner latches pivotally secured at their inner ends to the end-gate sections, and provided at their outer ends with elongated openings adapted to removably engage the necks oi said keepers, said openings being elongated to permit a limited movement of the end-gatesections toward each other when the end-gate is opened rearwardly; and means for securing the end-gate sections in rigid relation to each other.

In testimony whereof I aix my signature.
