Application filed February 24,1906. Serial No. 302,819.
To all whom it may concern: 7
Be it known that I, CONRAD MILLER, a
citizen of the United States, residing at the: city and county of 'Denver and State of: Colorado, have invented certain new and use- I ful Improvements in Dumping- Vehicles; and I do declare the=followingto be a full,v clear, and exact description'of the invention, such as will enable others skilled in the art i to which it appertains to make and use the:
same, reference being had to the accompany- I r the dumping position Fig. 4 is an elevation ing drawings, and to the figures ofreference marked thereon,- which form a part of this? specification.
My invention relates to improvementsin dumping vehicles.
My improvements are moreadapted for use in connection with wagons. My object isto provide a comparatively simple construction of this class which may be quickly and easily manipulated for dumping purposes As shown 1n the drawing and hereinafter described, the vehlcle is provided with two hinge members. the samebe-ing located onopposite sides of .the central portion of the vehicle, in which central portion is. located a dumping platform which may be tilted, to:
dump in either direction asthe contents of the. end members are discharged thereon.
My improvements also include means whereby the central dumping section. which preferably consists of two centrally hinged. parts, may be caused to fold downwardly thus discharging part of the load inv front and the other part in the rear of the central i part of the vehicle.
The construction is such that the operator can perform the entire dumping act by ma-g nipulating a lever located within convenient reach of the drivers seat constructed in the;
forward end ofthe vehicle.
It will be understood that my improved dumping construction may be employed tof advantage with any material-which it may be desired to haul about from place to place and discharged in bulk from the wagon body.
Having briefly outlined my improved con struction as well as the function it is'intended to perform, I will proceed to describe the same in detail reference being made to especially "lating chain. Fig. 9 but viewed at right angles thereto.
'Fig. 11 is similar to Fig. 9 but with the view of the same, the front part of the body being shown in section taken below the seat in order to better illustrate the manipulating devices. Fig. 3 is a central section taken through the same with the parts shown in showing the members in the dumping position but with the central dumping member centrally supported, its hinged parts being folded downwardly to discharge part of the load in front and part in the rear. Fig. 5 is a front end elevation of my improved.
dumping vehicle. Fig. 6 is a section'taken on the line 6-6 Fig. 4. looking toward the rear or in the direction indicated by the arrow; Fig. 7 is an enlarged detail View of the mechanism for manipulating the dumping members. F ig. .8 illustrates the same construction as Fig. 7 viewed in the direction at right angles to F ig. 7 Fig. 9 is an enlarged detail view illustrating'the cam lever employed in locking the manipu- Fig. 10 is, a view similar to cam in a difierent position. Fig. 12 is a cross section similar to Fig. 6 but showing the central dumping section in place and 1n position to dump the load at one side of the vehicle. Fig. 13 is a fragmentary section of the same but with the central dumping member raised to the closing horizontal posiftion.v Fig. 14 is an end view of the adjust-- .able walls located at the opposite ends of the central dumping section their function being ..to prevent the material to be dumped at either side of the vehicle from escaping in either the rearward or forward direction.
The same reference characters indicate the same parts in all the views.
Let the numeral 5 designate the frame work of the vehicle which is mounted upon wheels 6. 'Upon this frame work of the vehicle body are mounted two end dumping -members 7 and 7 each of which is hinged at 8 and whose extremities remote from the these devices will be su The lever is loosely mounted on the drum asshown at 14 and may be employed to turn the drum in either direction according to the position of the pawl 12. This dog may be made to engage the ratchet or toothed wheel 10 on either side of the lever and its position will determine the movement of the drum for a given movement of the lever arm. The pawl is easily shifted from one position to the other by operating a small arm 15 which is connected with the bolt or pin 16 which secures the pawl to the lever. Upon the hand lever is also fulcrumed a spring-actuated device 17 pivotally connected with the lever as shown at 18 and having a coil spring 19 acting upon one extremity thereof and forcing the other extremity downwardly upon the pawl 12 whereby the latter is caused to maintain any desired position of adjustment.
The hinge member 7 has two chains or other suitable flexible devices 20 connected with its forward extremity as shown at 21. These chains pass upwardly over pulleys 22 carried by a shaft 23 mounted upon the relatively stationary frame work of the vehicle. Another flexible device 24 is secured to and passes around the drum on each side ofthe vehicle, its opposite extremity being connected with a central dumping member 26- as shown at 24 while a branch flexible device 28 leading from the main flexible device 24, passes downwardly and is connected with the opposite side of the central dumping device as shown at 29. Still another flexible device 25 is connected at one extremity with the drum 9 and at its opposite extremity to a rod 56 slidable in guides 27 mounted on the frame work. As the flexible devices'and their connections are the same on each side of the vehicle a descri tion of one set of cient for both. The chain 24 is supported by a guide pulley 30 located on the upper part of the frame work; while the chain 28 is supported by a similar guide pulley 31.
Connected with the rod 56 at its rear extremity as shown at 32 is a flexible device 33 which passes over a pulley 34, its rear extremity being connected with the rear extremity of the dumping section 7 as shown at 35. The chain 24 on each side of the vehicle, passes through a shoe 36 in which is pivotally mounted a cam 37 with which is connected an operating arm 37 When it is desired to support the central dumping member on one side of the vehicle to allow its other side to tilt downwardly to the dumping position simultaneously with the assumption of the dumping position by the end dumping members, the cam lever is forced to the locking position or that indicated in Fig. 9, whereby the chain 24 on one side is locked in the shoe. Then as the drum 9 is rotated to operate the dumping members 7 and 7 the chains 24 and 28 on one side of the vehicle are not slackened while those on the other side are slackened to allow the central dumping member 26 to move downwardly to the position indicated by dotted lines in Fig. 3.
Attention is called to the fact that there is a locking cam 37 on each side of the vehicle and when this locking cam is thrown to the position to prevent the chain or other flexible device 24 from passing through the shoe 36, the chains 24 and 28 will be locked I against movement on that side while corresponding chains on the opposite side will be released and allow the corresponding side of the central dumping member 26 to. drop downwardly to the dumping position.
In case it is desired to lower the dumping member 26 to the horizontal positionyor allow bothsides thereof to move downwardly together, the cam 37 is thrown to the osition shown in Fig. 11 on both sides 0 the vehicle. In this event, by the proper ma nipulation of the drum 9, the two dumping members 7 and 7 A will be tilted to the dumping position while the central dumping member 26 will be lowered in the horizontal position.
In order to provide suitable walls at the opposite ends of the central dumping space, so that as the central dumping member is lowered, the material can neither fall forwardly or rearwardly but must pass to the desired side of the vehicle, and'at the same time not'allow these walls to project downwardly so far as to be in the way when the members are not in the dumping position, I employ at each end of this central dumping space two members 38 and 39 which when the dumping members are in the raised position, overlap each other as shown in Fig. 1 and at the same time are carried upwardly with the dumping member 26 by virtue of the fact that the said overlapping walls are provided with inwardly projecting lips 38 and 39*, respectively. These overlapping walls 38 and 39 are both connected with the stationary frame work of the vehicle, at each end of the central dumping space bypins 40 passing through vertical slots 41 formed in the central portion of the wall members. The pins 40 are provided with heads which moves downwardly. 'ing member m'oves downwardly on one side from above.
overlap the inner member 38 at each end of the space and prevent the members 38 and 39 from-slipping ofi the pins. At the same time these members slide freely on the pins during the raising and lowering of the central dumping member. The inner wall members 38 located at the opposite ends of the central dumping space, are connected at each side of the vehicle by a bar 42 which the central dumping member 26 engages as it As the central dumpof the vehicle, the two overlapping walls 38 and 39 move downwardly together, until the lip 43 on each member 39 engages a projection 44 on the stationary part of the frame work. After this occurs the members 39 cease to move downwardly, but the members 38 continue their downward movement by virtue of the pressure of the member 26 The members 38 are then allowed to move downwardly until the upper extremities of their slots 41 engage the pins 40. This range of movement is so regulated, as to allow the wall members 38 to move downwardly a sufficient distance to harmonize with the dumping position of the central dumping member 26. By virtue of the inwardly projecting lips 38 and 39 of the movable side walls, these walls are restored to their raised position as the dumping member 26 is carried upwardly in a manner that will be readily understood.
In order to permit the central dumping member to allow the load to fall directly underneath the vehicle, I divide the member 26 into two parts 26 and 26 these two parts being connected by hinge pins 45. When it is desired to cause the parts of the member 26 to move on their hinge pins 45, whereby each part is allowed to fall downwardly as shown in Fig. 4, the hinge pin 45 on each side of the vehicle is suspended by a link 46 which is passed upwardly through a beam 47, its upper extremity engaging a removable pin 48 inserted in the central stationary frame part 49 of the structure.
Attention is called to the fact that the vehicle is provided on each side of its central part with closed stationary members 49 which confine the central portion of the load at the sides when the central dumping memher is in the raised or closed position. Now assuming that the hinge pins 45 are suspended by the links 46, if the shaft 9 is manipulated to release the flexible devices 24 and 28 on opposite sides of the vehicle, the two parts 26 and 26 will fall downwardly to the position shown in Fig. 4 allowing the load to dump immediately beneath the vehicle, part of it toward the front and part toward the rear. In this event the parts 26 and 26 of the central dumping member leave the lips 38 and 39 of the movable walls. But when the parts of the central normal position, they rengage the lips 38 and 39 and lift the movable wall parts to their normal position.
From the foregoing description the use and operation of my improved dumping vehicle will be readily understood. Assuming that it is desired to dump the load to either side .of the vehicle, the cam lever 37 is thrown to the position shown in Fig. 9, on the opposite side of the vehicle whereby the flexible device 24 is prevented from passing through the shoe 36 on that side. Then as the shaft 9 is properly manipulated, the flexible devices 24, 25 and 28, the rod 56 and the flexible devices 20, are operated to throw the dumping members 7, 7 and 26 to the dumping position. It will be understood that by virtue of the fact that the flexible the opposite side the corresponding flexible device will run through the shoe and allow the central dumping member to move downwardly on that side. When, however, the suspension links 46 are connected with the hinge pins 45 of the central dumping member, the cam levers 37 must be released on both sides of the vehicle, so that the chains 24 are allowed to run through their shoes 36 as will be readily understood, from an in spection of the drawing, reference being made particularly to Fig. 4.
