JOHN W. HAYWOOD, OF B.-\LD\\'I.\'SVILLE, NEW YORK.
DUMP-WAGON.
Specification of Letters Patent.
Patented Sept. 15, 1908.
Application filed November 1, 1907. Serial No. 400,!-
To all whom it may concern:
Be it known that I, JOHN W. I'IAYWOOD, of Baldwinsville, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Dump-Wagons, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to certain im )rovements in dum wagons in which the ox is preferably mat e hopper shape with an open.- mg in the bottom and provided with a forwardly swinging bottom door adapted to discharge at its rear end, and refers more particularl to the adjustment and manner of control ing the operation of the door.
My main object is to provide a general utility dump wagon Which is specifically adapted for road making and similar u es a where it is desired to spread the load evenly to an desired depth, during its discharge. In 0t \er words I have sought to provide means whereby the operator may easily stop and hold the door in any position in its arc of movement during the discharge of a load so that such load m: be spread out evenly over the surface of the ground or may be wholly discharged at once without stopping the wa'zon.
Anotdicr object is to extend the sides of the door upwardly some distance above the bottom at the outer sides of the box-so as to retain the load against lateral discharge during the operation of spreading or discharging such load graduall A still further object is to hinge the front end of the door to, and some distance above, the bottom of the box so that the arc of movement of the front end of the door will be as high above the ground as possible when the door is swung to its open position.
Another ob'eot is to )rovidc the sides of the door and l)0.( and a so the guard plates which form a part of the door support with a plurality of apertures for receiving the hin e pins and permitting the swingin axis of the door to be shifted nearer to or fin'ther from the front side of the bottom of the box.
Other objects and uses relating to the specific arts of the door controlling mechanism will e brought out in the following description.
In the drawin s-Figure 1 is a longitudinal vertical sectiona view of a dum wagon embodying the various features 0 my, invention. away of the wa on box showing the door as partly open and also showing the adjacent portion of the door controlling cable. Figs. 3 and 4 are transverse sectional views taken respectively on lines 3-3 and 4-l, Fig. 1, except that they show the full width of the box and that one end of the winding drum and its bearing is shown in section. Fig. 5 is a to plan partly in section of one end of the wim ing drum and its operating mechanism showing also the adjacent portion of the box.
In carrying out the objects stated, I provide a hopper shaied box having substantially vertical parallel sides 1-, front and rear downwardly inclined ends land 3 and a rearwardly inclined bottom door-4-.
The main bod of the box is made of wood and is provider with an interior lining of sheet metal and the rear end 3 extends downwardly some distance below the lower plane of the front edge 2 while the lower edges of the sides 1 are disposed in a plane coincident with the lower edges of the front and rear ends, which latter are spaced apart some distance leaving an opening 5 in the bottom of ample size for the discharge of the material.
The bottom door -4 is preferably made of sheet metal of suflicient size to completel close the opening --5- and is provided witoppositc upturned integral flanges or sides 6 extending some distance above the bottom and in close proximity to the outer sides of the box, the front ends of said sides -6- being wider than their rear ends and are hinged to the sides of the box by suitable pivotal pins or bolts 7 and also to the inner sides of suitable sheet metal hangers or brackets -8- which are secured to the outer sides of the box. These sheet metal hangers or brackets -8 and also the upper front end of the sides -6 of the door are formed with a series of apertures spaced apart one.
above the other to receive the pivotal bolts -7- and permit the latter to be adjusted nearer to or further from the bottom of the door so as to raise or lower the arc of movement of the front end of the door to bring the latter nearer to or further from the ground as may be desired and also to vary the speed of openim of said door.
The front and rear ends of the bottom of the door are reinforced by suitable cross bars F i 2- is a side-elevation partly broken I 9 and 10 of wood or other suitable material, the rear cross bar being in close proximity to the rear edge of thedoor and provided with a series of end and intermediate guides or loops -1 land12-for recei ing a cable 13* by which the action of the door controlled. In the present instance employ a single cable having its intermediate portion iassed under the rear edge of the bottom 0 the door and upwardly o'ver suitable idlers -l4 and then forwardly at opposite sides of the box where their ends are attached to suitable winding drums -15-. 'lhese winding drums are secured to a tubular shaft l7 which is journaled in metal bearings -lS in the sides of the box, said shaft being provided near one end preferably just inside of the right hand side of the box with a worm gear l6- meshing with an upright worm 19-, the latter being 'ournaled in a swinging bracket 20 and is provided with an upwa rdly extending shaft -2 1-- having a handle 22 b which it may be rotated to transmit simi ar rotary motion to the tubula r shaft 1 7 and drums 15.
The swin ing frame or yoke 20- is pivoted at its ower end at --23- to the adjacent'side of the box and preferably consists of a U-shape metal bar having its opposite ends mounted upon the pivotal bolt 23 and its upper portion disposed in a horizontal position forming a bearing for the shaft -2 1 although the lower end of said shaft is stepped in a cross bar -24- forming a part of and secured to the bracket -20-. This bracket may be rocked forwardly from the shaft -17- to throw the worm -t9 out of mesh with the gear 1 6 when it is desired to discharge the full load at once.
The bracket -20 is held in operative position by a detent 2S which )ivoted at 29 to the adacent side of tae box -l and is provider with a handle or pedal 30 by which it may be thrown out of en gagement against the action of a retracting spring -3l although this spring serves to ho d the detent in operative position to hold the worm -l9 in mesh with the gear -16 The particular object in using the wornr gear as means for winding the door operating cable is that it is self-locking and enables the operator to control the opening action of the door under load in which case the detent S and worm -19 are left in operative position and the worm is simply rotated in the direction necessary to unwind the cable, thereby allowing the rear end of the door to open as much as may be desired to dis-- charge the load b slow degrees therebv spreading it out to t to desired depth over the ground.
The cable -13- 18 free to render through the guide loops or eyes 11 -and .12
should one side of the door sag or lag behind the other in closing and affords a means for closing both sides of the doors tightly al though the transverse movement of the chain under .the doors is comparatively slight under all conditions.
'lhe idlers --14 are journalcd in brackets H which are secured to the outer sides of the ,box and in order to )revent undue slackening of the portion of t to chain between the itllers and drum, I provide additional guides -l3 also secured to the practically the entire strain of the load upon the door is borne by the chain but any sa or depres ion of the door may be readily taken up by rotating the worm v 1 9 in the proper direction to further wind the cable 13.
hen the doors are closed in the manner 'ust described they are held in this position y the intertncshing teeth of the worm and gear and if it is desired to discharge the entire load at once, it is simply necessary to disengage the detent 2S from the swinging bracket 20 and to rock said bracket together with the worm 19 and shaft -2 1 thereon forwardly to throw the worm out of engagement with the ear whel cby the drums are free to rotate unt er the tension of the cables produced by the weight of the load on the door, such load forcing the door to its extreme open position. On the other hand if it is desired to distribute the load evenl over the surface of the ground, the worm is left in mesh with the gear and the detent remains in holding engagement with the bracket whereupon the worm may be rotated by the operator through the medium of the hand piece -22-- and shaft 21 to permit the cable to be unwound gradually until said door is opened to the desired degree when the rotation of the worm is stopped, thereby locking the drum shaft against further rotation and holding the door in its adjusted position through the medium .of a cable 13-.
What I claim is:
1. In ad ump'wagon, a dump box having a longitudinally swinging bottom door, and means for changing the position of its axis.
2. In a dump wagon, a dump box having a,
the box some distance in front of the front 'otal bolts passed through 1 downwardly and forwardly swinging bottom door, and means for changing the position of its swinging axis.
3. In a dump wagon, a dump box having a downwardly and forwardly swinging bottom door provided with upwardly pro'ecting sides extending under the outside of t e box some distance above its bottom, supports for the door secured to the sides of the box, said supports and sides of the door being provided with a plura'ility of apertures, and pivined a )ertures at the opposite sides of the box, said olts being adapted to be placed in either of the apertures to change the position of the swinging axis of the doors.
4. In a dump wagon, a dump box having a downwardl y and forwardly swingin bottom door, and adjustable pivots for sai door.
5. In a dump wagon, a (lump box having substantially parallel sides and downwardly converging front and rear ends, the rear end extending downwardly a greater distance than the front end, a downwardly and forwardly swinging bottom door having upwardly extending sides hinged to the sides of the box, the hinge-bearing being adjustable to 'ehange the swinging axis of said door, and
means for controlling the operation of the door.
6. In a dump wagon, the combination of a dump box having a longitudinally swinging bottom door, a cable controlling the action of said door, a drum for winding the cable, a worm gear on the drum, a worm movable into and out of mesh with the gear, a swinging supporting frame for said worm, means for rotating the worm, and a detent movable into and out of holding engagement with said frame.
7. In a dump wagon, a dump box having a longitudinal swinging bottom door, means for controlling the action of said door ineluding a worm and gear, one of the latter parts being movable into and out of engagement with the other part, means for rotating the worm, a swingin su )porting frame for said movable part ant a t etent movable into and out of engagement with saidswinging frame.
In witness whereof I have hereunto set my hand this 21st day of October 1907.
