WAGON.

' Application filed April 26, 1920. Serial No. 376,600.

Be it known that LCHARLEs N'. CLARK,

'a citizen of the United States, residing in Somerville, county of Middlesex, and State of Massachusetts, have invented an Improvement in WVagons, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to-wagons of the character employed for j delivering coal,

gravel and like material and more part1cu larly to wagons having a tail board or end 7 capable of being moved from both of its described.

The invention further has for its ob ect stood.

open positions into its closed position by 'mechanical means, as will be described.

The invention also has for its object to provide a simple, inexpensive and efiic ent construction of tail board. of the character to providethetail board with a novel con-' struction of guiding members for coal, as will be described. These and other features of the invention will be pointed out in the claims at the'end of this specification.

'Fig. 7, a section'on the line 77, Fig. 5, and j Fig. 8, a: detail of the sliding cover and wings to be referred to.

Referring to the drawing, 10 represents the wagon body which may be of any suitable or usualconstruction, and '12 the tail upper pivot forthe board or end gate therefor. The tail board 12 as 'herein'shown is pivoted at ,its upper and lower ends, the pivot for'the upper end being shownas a rotatable shaft or rod18 extended through a suitable hole in the tail board and. provided at'its opposite ends so i with cranks 14:, 15,-w'hich in the normal or r closed position of the tail board hook over "pins or lug 16, 17, carried by the sides of the wagon body- 10. -The crank or arm 15 cooperates with a spring member 18 attached to wagon body 10 so as to frictionallyhold the cranks 14, 15 in locking'engagement withthe pins 16, 17 against accidental disengagement, while permitting them to be readily disengaged by the operator turning the shaft 13 in the proper direction through a" handle 19 on the crank 15, when it is desired to lower the tail board :12 into a horizontal or shoveling position'shown in Fig.3.

The tail board 12 is provided at its lower end with a pivot shaft or rod 20, which is normally supported in bearings, shown as hooksor bentrods or arms 21 projecting radially from a shaft 22 rotatablymounted in bearings, shown as staples or eyes 23 attached to the wagon body 10.

The rotatable shaft 22 is providedat one end with a substantially long crank or arm 24, by means of which the operator can turn the shaft 22 so as toloiverthe hooks or bearings 21 from the pivot rod 20, see Fig.

1, andthus disconnect the lower end ofthe tail boardfrom the wagon. body, to allow the operator to turn thetail board on its upper pivot 13 and move its lower end away from the wagon body into 'its dumping position'shown in Fig. 4, in which position an opening is afiorded for the passage of-the coal'out of the wagon body especially. when the front end thereof islifted.

Provision is made for closing the open ing referred to'at the oppositesidespf the tail'board fora substantial distance above the latter, so'asto avoidlateraldis'placersubstantially a quadrant of a circle and is provided with a substantially horizontal bot tom edge 26, a substantially vertical outer edge 27-and acurved edge 28. --The closure member is loosely mounted 'on the lower pivot 20 for the'tail board, and is connected with the tail board by a'pin'and-slot-com nection, bent pin 30 afiixed to the tail board beingextended through a curved slot 31 in the closure member 25, the pivot 21) constituting the center for the curved slot 31. This pin and slot connection allows the tail board to be moved outward ifroin its closed or vertical position shown in Fig 1, into its open or inclined position shown in Fig. 4 with the side closure members movable in a substantially straight direction with the front or free end of said closure,

member sliding across andbeing support-ed by the shaft- 22.

Provision is made for moving the tail board into itsclosed'position from its open shoveling position'and from its open dump- ,ingiposition, with a minimum effort on the part o ftheoperator. To this end, they clo i sure members25 on opposite sides of the tail board are connected to a Windlass or rotatable'shaft &0 extended transversely under the wagon body and suitably supported therefrom. The shaft a0 is preferably connected with the closure members by chains 41, which are showna-s engaged with hooks 42attached to said closure members. The shaft 40 is provided with a handle 43 for turningit and with a ratchet wheel 4A;fwith which cooperates a holding pawl 4:5pivoted tothe wagon body.

.4 Provisionis also made for sustaining the tail board and the weight of the coal thereon of the hooked member 46 and is engaged thereby when the tail boardiis in its shovel m position, see Fig 3, and from which said 2 hookedm'eniber is automatically disengaged when the Windlass is turned to wind the chains 41 thereon.

v Provision'is also made for retainingthe bearing members'QI for thelpivot 20 of the A tail board in operative relation with the latter agains't accidental disengagement To this end, the wagon body 10 hasse cured to it a springmeinber 5O betiveen the outer end of which and the'wagon body the tree 7 end of the cranlr or arm 24 is normally it is desired to move the crankor arm 24 placed, The crank or arm 24 possesses sufiicient spring'to enable it tobe moved downward suiiiciently to remove it from engagement with the spring'member 50, when up into'the positionshownin'Fig; 1 and therebyvrelease the pivot 20 ot thetail board;-

, The tail board may andp'referablywill be p-rovided with-the usual openin'g'52, see

Fig.- 5, through which the coalma'y beldisa charged with the tai'lzboard in its closed a basketor other receptacle placed in line with said opening, whereby loss of coal and the labor and time of cleaning up the sidewalk or driveway after the coal has been delivered may be reduced to a minimum. To this end, the, tail board is provided with wings, or movable guiding members 5a, which are irnounted to turn on stationary vertical pivot rods 55, and which are provided with curved upper surfaces 561 suit; ably shaped to ha-vea cam action and which cooperate with the lower edge of the sliding cover 535 so that when the said cover' is moved downward to close the opening 52,

the lower edge of said cover will slideover' the upper curved surface 56 andwillturn the coal guiding members 54011 their pivots from their open position]represented in Fig. 7 into their closed position, 'in';which they extend across the opening 52 substantially in the plane of the tail board. Thefsliding cover 58 is movablebetween vertical guides 58 and may be moved by a'lever 59 in a manner well understood.

From the above description it will be, seen that while the load is in transit, the tail board is in its closed position shown in Fig. I and is held vin this position by the holding pawl 45 otthe Windlass.

.VVhen it is desiredto shovel the load from the wagon, the'tail board is moved into its horizontal position. shown in Fig; 3, which is effected by the operator throwing back the holding pawl .5, and rotating the upper pivot or shaft-l3 to release the upper end of the tail board, which leaves the latter tree to be turned downby gravity assisted it may be b ytheoperatorl until. theho'oked members 46 engage the stops or sustaining members 4:7,;18' shown in Fig; 3. It it is. desired to dump the 00211, the handle or crank 24: is disengaged fromits. holding member 50 and turned up into the position shown in Fig; 4. soasTto release ,the tail board at its lower end, which is then pushed outbv' the load into the position shown in Fig. 4:. i

()ne embodiment of the'invention is herein shown, but it is not desired to limitthe invention t6 the particular constriiction shown.

From the above descriptiom it will be seen that a single operator from one side of the wagon can control the tail board so that it can be placed into a shovelling position or:

into a dumping position as he desiresand can close the tail board from either position and lock it in its closedpositiOn. i

The pin and slot connection 30', 31, ispreferably arranged so that the pin30 is imade shorter than the length ofslot 31 and is capable of being turned into alignment with the slot so as to permit the side closure mem- V bers 25 to be sprung laterally and disengaged from the pins 30, and thereby leave the tail.

board, when released at its upper end, to be turned down into a substantially vertical position on the pivot 20, when it is desired to load the wagon body by shoveling from 2. The combination with a wagon body, of

a tail board pivotally secured thereto at its upper and lower ends, means for detachably securing said pivoted upper and lower ends to said wagon body, side closure members pivotally secured to the lower end of said tail board, and a Windlass carried by the wagon body and connected with said side closure members to move thetail board from both of its open positions into its closed position.

3. The combination with a wagon body, of a tail board pivotally secured thereto at its upper and lower ends, means for detachably securing said pivoted upper and lower ends to said wagon body, side closure members pivotally secured to the lower end of said tail board, and mechanical means carried by said wagon body and operatively connected with said side closure members to move the tail board from both of its open positions into its closed position.

4;. The combination with a wagonbody, of a tail board cooperating therewith, upper and lower pivots forsaid tail board carried bysaid tail board, means on the wagon body co-operating with the upper pivot to secure the latter to the wagon body, side closure members co-operating with said tail board and wagon body and inwhich the lower pivot for the tail board is mounted, means for. con-- necting the side closure member with the tail board to permit the latter to turn on the lower pivot and be moved with respect to said side closure members, and means carried by said wagon body for detachably supporting the lower pivot for the tail board. 7

5. The combination with a wagon body, of atail board or end gate therefor provided with an opening for the discharge of the contents of the wagon body, pivoted side guides for said contents cooperating with said opening, and a slide to cover said opening cooperating withsaid side guides to automatically turn the same from: their op'er-,

ative into their inoperative position, when said slide is moved to close said openlng.
