JOHN HEBERLING, OF ROCHESTER, NEW YORK.

DUMPING-WAGON.

Specification of Letters Patent.

Patented Jan. '7, 1908.

Application filed February 6. 1907- Serial No. 355.975:

.To all 'whom 'it may concern:

Be it known that I, JOHN HEBERLING, of

` Rochester, in the county of Monroe and State of New York, liave invented certain new and useful Improvements in Dumping-Wagons and I do hereby declare the following to be a full, clear, and exact descri tion of the same, reference being had to t ie accom anying drawings, forming a part of the speci icationk and to the numerals marked thereon.

My present invention relates to dumpingwagons and particularly to that class in which the wagon box comprises movable bottom sections or doors and it has for its object to provide an improved mechanism for operating these parts into the closed position, whereby the operating connections may be automatically adjusted to permit one door to be closed in advance of the other and both of them to be drawn tightly against the bottom of the wagon box.

To these and other ends the invention consists in certain improvements and combinationsof parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a top plan view of the wagon box illustrating the application thereto of devices constructed in vaccordance with my invention. Fig. 2 is a longitudinal sectional view taken onthe line 2X 2X of Fig. 1. Figs. 1a and 2a are views showing respectively, a top lan and a longitudinal section of the type opdumping wagon provided with a longitudinally extending winding shaft and illustratinfr the application thereto of devices contro led in accordance with my invention. Fig. 3 is a rear elevation shown partly in section taken on the line 3X 3X of Fig. l. Fig. 4 is a similar view showing the bottom sections or doors in the open or released position. Fig. -5 is a perspective view of the equalizing member detached from the wagon box. Figs. 6 and 7 are views showing different ways of attaching the door operating connections to the equalizing member. Fig. 8 is a view showing a modiiication of the means for automatically adjusting the equalizing device. Figs. 9 and 10 are views similar to those shown in Figs. 3 and 4 illustrating another form of the equalizing device, in which the latter is shown in the two positions of adjustment which it assumes when the bottom sections are respectively closed and opened. Fig. 11 isf,n

detail view of the device shown in Figs. 9 and 10, and Fig. 12 is a sectional view taken on the line 12' 12X of Fig. 1EL showing the rear end of the wagon box.

Similar reference numerals in the several gures indicate similar parts.

In illustrating my invention, I have shown the devices embodying it applied to the body portion or box, of a dumping wagon comprising the side pieces 1 and 2 between which are located the forward and rear ends 3 and 4,- respectively. It is customary in wagons of this character to extend the side pieces' at their forward ends, as shown, where they are connected by afoot board 5, and at their o posite extremities which are connected y a cross piece 6, which latter, with the board 5, forms a convenient means of attachment for mounting the wagon body on the usual running gear, which has been omitted from these illustrations.

The bottom sections or doors 8 and 9 extend lon itudinally beneath the ends and sides of t ie box and are ivotally connected to the latter by suit able hinges 10, their inner proximate edges meeting midway between the sides 1 and 2. Extending transversely of the wagon box between the extended forward ends of the side pieces 1 and 2 is a shaft 16 journaled at its ends in bearings 17 and rovided at its center with drums 18 and 19 in which the door operating connections 20 and 21 are adapted to be wound. These connections pass downwardly between the guide ulleys 22 and 23 and thence longitudinally beneath the respective bottom sections or doors 8 and 9 to the rear end of the wagon box where they are attached to the equalizing device to be presently described. At one end of the shaft is a ratchet wheel 24 by means of which the shaft may be rotated .to close the bottom section by engagement therewith of the pawl 25 carried on the oscillatory operating arm 26. The ratchet wheel is normally locked by a detent 30, arranged in a housing 31, which may be released by a treadle or foot lever 32. Attached to the arm 26 is a pivoted releasing member 33 having a laterally projecting finger 34, extending beneath the pawl 25 and a projecting end 35 which is adapted to cooperate with the end of the box, when the o erating arm is moved into the position s own in Fig. 1, to automatically adjust the -pawl into the inoperative position. The

advantage of this means of releasing the iio j pawl 25 will be apparent from the fact that the latter may be disengaged by the operator beforethe shaft 16 is released, by the retracting of the detent 30, or if the o erator neglects to do". this, the pawl wil automatically be disconnected as the o erating lever is rotated into the position siiown in Fig. 1, by the movement imparted to the shaft 16 as the door operating connections are permitted to unwind.

To adapt a Wagon of this character for transporting finely divided material, such as sand, or plastic substances such as asphalt, mud or plaster, itis necessary to provide means for closing both bottom sections or j doors tightly into engagement with the bottom edges of the box and to cover the joint formed by the meeting edges of the two bottom sections with a covering strip or hatten. Considerable inconvenience has been encountered in using these wagons for the above mentioned purposes, which is due in a large measure to the wear and unequal stretching of the door operating connections which permits one door or section to sag at one or both of its ends when the other is drawn into engagement with the box. My present invention comprehends means whereby this diiiculty may be 'obviated which also permits a relative automatic action to take place between the-door operating connections whereby the closing of one of them in advance of the other may be assured, thus permitting the application of the covering strip or batten to one of the doors, without providing a special form of winding mechanism for taking up one connection independently of the other, which is advantageous, as it does not require skill or particular attention on the part of the operator.

In illustrating the present embodiment of my invention I have shown the preferred form thereof in Figs. 3 and 4, in which the equalizing ofthe connections is accomplished by supporting one end of each of them on a guiding projection or idler mounted on the box and providing means serving as a connection between them, whereby as one connection is drawn over or wound upon its guide or projection in one direction the other is permitted to unwind or move over its respective guide or projection in the opposite direction. One form of mechanism for accomplishing this object may comprise a connection, such as a transversely movable bar 50, reciprocating in bearings formed in the ends of a bridge piece 51 mounted upon a bed plate or strap 52, secured to the rear end 4 of the box, and two guides such as projections or idler pulleys 55 and 56, located beneath the bar.

The door operating connections 20 and 21 extend upwardly at the rear ends of the doors around the guides55 and 56 and are attached to the bar 50 at points located laterally of the centers of saidpulleys, whereby the bar, or connection between the chains, may be reciprocated in one direction or the other when a greater strain is imparted to one of the connections than to the other. This arrangement of the parts, it will be seen, provides mechanism which is automatically adjustable to compensate for the unequal length of the operating connections caused by an unequal wear, or stretching, of the chains which are usually employed for this purpose, so that when the shaft 16 is rotated to 'Wind up the connections, the lateral movement of the equalizing bar will pay out to the shorter chain an amount equal to that portion of the longer chain which must be taken up to close its door, thereby enabling both bottom sections'or doors to b e drawn tightly against the bottom of the wagon box.

It will be seen that if the equalizing bar is moved to one side or the other when the doors are opened that the connection which is shortened temporarily will operate to close its door or bottom section in advance of the other and that a mechanism for adjusting the relative lengths of said 'connections or chains may be provided to cause the door which 'is to be closed first to precede the second a suficient distance so that a lip or projecting batten on the edge of the latter will not strike the former when the edges of said doors approach cach other in their closing movement. In reality the necessary adjustment of the chains orconnections to accomplish this object is slight, as thelength of one of them is increased the same amount that the other is decreased. In this connection it is desirable to provide means for posil tively actuating the equalizing mechanism to eiect the aforedescribed adjustment, which is preferably operated automatically by one of the doors when they are released.

The covering strip or hatten is designated by the numeraI 57 and is shown as applied to the door 8. In order to close this door after the door 9 I arrange in the chain or connection 2l a bar or link 58 which bears against the face of a rojection or roller 59 located beneath the id er 56, and is connected to the equalizing member by a short section of chain 21a. The upper end of the bar or link projects above the roller and its lower end extends into proximity with the door 8 when the latter is closed, as shown in Fig. 3, the various coperating parts being arranged so that when in its normal position the bar extends substantially in a vertical direction and is held inV engagement with the roller 59. N ow, when thedoors are released it will be seen that as they rotate about their pivots or hinges 10, their meeting edges separate and that the connection 21 is carried laterally by the edge of the door 8, out of alinement with the lower end of the .bar or link 58, as shown in dotted lines in Fig. 4. This move'- ment of the connection or chain tends to rotate the bar around the projection or roller 59., Vas a fulcrum point, before the doors have reached .their limit .of outward movement and while the connections or chains are unwinding from the drums. The drawing -of the bar or linlr .into alinement with the .chain 21 causes the connecting section 21, between it and .the equalizing device, .to -be drawn over ythe idler 56 to move the equalizing device longitudinally inthe direction indicated by the arrow in Fig. 4, whereby the connection 21 is lengthened and the connection 2() is shortened.

The modification shown in Fig. 8 illustrates another way the equalizing device may be moved automatically, which consists in connecting one of the doors 9a with the end of the equalizing Vbar 50 by a short length of chain 59 attached to said door near its pivotal point, as indicated by 60.. When this form of actuating means yis employed, the connection should be attached to the door which is to be closed in advance of the other door, which is indicated by 8a, and its length should be such that-the tension applied thereto by the weight of the .door as lit approaches the limit of its opening movement will overcome the riction of the operating connection 20a.

In Figs. 9, 1() and 11 a modification of the form ol equalizing member is shown, which operates to adjust the door operating connections or chains without reference to the doors themselves, but which may be used 4in conjunction with either of the actuating devices shown in Figs. 4 or 8. These illustrations show the member as being formed of a short length of channel iron, the side walls 61 ol which are adapted to rest on the edges ol the guides or idlers 55a and 56EL at opposite sides of the chains and 121, which latter are secured at their ends by pins c and l). The edges of the side walls 61 are provided with inclined surfaces 55b and 56b which are adapted to cooperate with .the idlers 55a and 56EL to cause the equali-zing member to move vertically when it is operated. The member is given a natural inclination to move in one direction by making the inclined surfaces of sufficient length in proportion to the distance through which it moves, so that they always bear against the projections or idlers, as shown in Fig. 9. An equalizing member constructed in this manner will gravitate into the position shown in Fig. 10, when the doors or bottom sections are released.

It is not necessary to pass the door operating connections between the separate guides or idlers 55 and 56 as they might be arranged as shown in Fig. 7, in which they bear against the outer sides of the guides, nor it it necessary to employ two separate guides as a single projection may be employed, .as shown Fig. 6,y which may be formed by journaling Athe two idlers -on a common pivot.

Each, of the equalizing devices I have shown is capable of operation with 'equal 70 advantage when the winding shaft 1.6a is extended longitudinally of the wagon box, as shown in Figs. la and 2, but insuch xease I prefer to locate the wind-ing .drums 3.9 and 40 at .the rear end of the shaft .and locate 7-5 the equalizing devices, indicated by 50a, .at i the forward end 3 of the wagon box. The door operating connections 48 and 49 are then supported .at the rear end of thewagon box 4a .by guides 46 .and 47 .arranged out of 80 horizontal alinernent and above the inner edges of the doors 8b .and 9b, as shown Ai-n Fig. 12. These guides are mounted on Ytwo diagonally arranged str-aps 43 .and 44 which extend at an angle from the upper .corner lof 8-5 the end 4a and overlap .at their lower ends for the purpose of strengthening -the end y.of the box. The winding shaft 16, shown these figures, is supported at its lends in bearings 17a and Vat its `forward extremity is 90 provided with a ratchet -wheel '24a with which coperates the pawl 25a, o n the loperating arm 26, and .is lnormally locked by a detent 30a, pivoted on :a plate 31a, which may be released by a treadle `32a on .an 95 oscillatory shaft 33a having at its end a Aprojection (not shown) adapted -to disconnect said detent.

The devices embodyin -my invention may be manufactured cheap y and applied to 100 wagons heretofore constructed, and .owing to their simple construction they are not liable to injury or derangement as a result of the severe use to which devices of this nature are subjected.
