DuMPING-WAGON.

Specification of Letters Patent.

Appleman fusa october 4,1906. serial No. 337,402.

forming a part of the specification, and to the reference? numerals marked thereon.

My present invention has for its object to provide an improvedmeans of operating the movable sections or doors of dumping wagons, wherebypne of them may b e closed in advance of the other, which is so arranged ltliat'when the doors are in the normal `closed position ,the corners or ends of their adjacent or meeting edgesmay be held tightly in engagement with the bottom of the box.

My invention has for its'further object to provide a single `connection between the wagon box and bottomsectionsor doors and Winding mechanism which will enable the doors to be drawn and held tightly in closed position, without regard to the lengthening of said connection by its elonition caused either by its stretching' or wear, or-b'y the wear of the parts with which it cooperates. g

l'lo these and other ends the invention consists in ceri' tain improvements and combinations of parts all as will be hereinafter more fully describedfthe novel features being pointed out in the claims at the end of the speciication. .l

In the drawings: Figure l is a top plan view of a wagon box illustrating the devices constructedinaccordance with my invention.4 Fig. `2 is afront elevation. thereof partly in section. Fig. 3 is a similar viewof the rear end of the wagon box: Fig. 4 is a perspective view showing the bottom sections or doors, the winding drum and the'means of attaching the connection for operating the doors. Fig. 5 is a top plan view similar toV Fig; 1 showing a modified arrangement ofthe winding mechanism. Fig. 6 is a perspectiveview of said modication similar to Fig. 4. Fig. 7 is a detail view.

Similar reference numerals in the several figures Vindicate similar parts. I

I n illustrating my invention, 1 have shown it applied to a wagon box of the usual construction comprising side pieces 1 and 2 and forward and rear endpieces 3 and 4 respectively. Arranged beneath the box are two longitudinally extending bottom sections or doors 5 and 6 pivoted to the sides ofthe box, as indicated at 7, their inner edges meeting at the center oi the box, the joint formed between them being closed by'a projecting lip in the form of a batteri 8, shown in the present instance as attached to the lower side of the door 5 The winding shaft 9 is journaled at its ends'in bearings on the sides 1 and 2 oi the box and'is provided with the wind- I mg drum 10 and also with the ratchet'wheel 11 with which cooperates a pawl 12 mounted on an operating handle v13 by means of which the shaft be rotated.

The latter is locked by a pawl 14, shown in Fig. 2, arranged below the ratchet wheel which may be'released by a pivoted lever 15, shown in Fig. 1., adapted to be moved-by pressure of the operators foot.

On the rear end 4 of the wagon box is arranged a projectionin the form of a pulley or sheave 16 mounted on y a strap 17 which may be bolted or otherwise secured' rigidly to the box above the lower edge thereof. The flexible connection 18 which I employ lfor operating the doors may be either a cable or chain, although I prefer to employ the latter. This is looped over the projection 16, the two ends ofthe loop thus formed be'- ing carried forwardly beneath the two doors .5 and 6,

`the' extremities 12?a of one oi the said ends being at tached to the winding drum 10 and the other extremity 18b being anchored stationary relatively to said drum by attaching it to a hook `19 formed on a strap 20 securedto the front end board 3. Means are provided on each of the doors for holding the connection or chain in position near their, inner edges, and to reduce the friction-oi the connection onthe doors as the end portions thereof are moved longitudinally beneath them,

I provide each of the doors at their forward and rear ends with pulleys or sheaves 21 beneath which are retaining'loops 22 preventing the disengagement oi the connection.

It will be understood. that the door operating connection 18 is made oiV suhcientlength to permit both vdoors to be open to their fullest extent. This length is i determined byapplying the connection to the doors when in an open position, the extremity 18 being attached to one end of the drum l0 which is preferably made conical in shape .and provided with a helical groove. The `larger end of thedrum upon which the irst 'few turns oi the connection is wound' to takel it up and bring the doors quickly into a closed position is lo cated at one side of the center of the -box and to guide the chain or the connection, when the doors are in an open position, a projection' inthe giorm of a roller 23 `is arranged upon the front end of the box beneath the4 smaller end oi the winding drum, as shown in Figs. 2

and 4."

,It will be noticed that the connection passes directly `from the winding-drum longitudinally beneath one o the doors to the rear end thereof, thence over'the projection or sheave 16 and returns beneath the other door to its place of rigid attachment or anchorage. The batten or covering strip 8 is located on the lastmentioned door, or the one which is operated by the end oi the loop of the connection having its extremity anchored, as this is the door which must be brought into the closed position after the other one. The successive closing oi the doors, upon winding theconnection, is caused by the friction imposed upon that portion oi the connection, or end of the loop which-must be' drawn over the projection or sheave 16, therefore, ay

greater force must be exerted to draw the connection aroundrthe projection to close the door, operated by this portion of the connection, than is required to wind up the other portion, or that part extending between said projection and the winding drum. As the doors are approximately equal in weight, the one (6) operated by the more freely movable end 18 ofthe connection will be brought Vinto the closdposition, as shown in Figs. 2 and 3,V in advance of the other and maintained in this position until the second door (5) is closed, as shown in Figs. l and 4.

The modification of my invention, illustrated in Figs. 5 and 6, embodies in addition ttthe chain o'r'co'nnection,

heretofore described but designated in these figures v as 24, a winding shait 25 extending longitudinally of the 32 which may be mounted upon a strap 33 extending' diagonally of the wagon box, to which the stationary end of the chain may lso be connected as indicated at 34.

In Fig. I have shown a detail view of a modification of one of the parts which may be used in place of the sheave 16. In thisview the projection at the end of the box over which thelchain or connection passes,is made in the form of a curved flange l16 on a ettari-19Ll its surface being grooved, as shown, to receive and guide the connection as it is drawn thereover. i

By employing a continuous connection which passes from the winding drum at one end of the wagon box `beneath one of the d'oors, thenccovera projection located at the opposite end ol the box and beneath theV otherdoor,l I am enabled to close oneof them in advance of the other and to bring both the iront and rear corners of the doors tightly into engagement with the box", irrespective oi any looseness ot 'the parts which may be occasioned by wear or stretching of the chain or wear of the sheaves, orprojeetions, over which it passes. i
