MATASHIRO YOSHINO, 0F DAIREN, MANCHUR-IA, AND CHARLES NOEL EDGE, OF SHANGHAI, CHINA; -SAID EDGE ASSIGNOR T0 SAID YOSI-IINO.

DUMPING-WAGON.

-To all whom it may concern:

Be it known that we, MATAsHIRo YosHINo. a subject of the Emperor of Japan, and CHARLES NOEL EDGE, a subject of the King of Great Britain, and residents of Dairen, Manchuria, and Shanghai, China, respectively, have invented certain new and useful Improvements in Dumping-Wagons, of which the following is a specication..

This invention comprises improvements in and relating to dumping wagons and has more particularly for its object to provide improved means for actuating the dumping doors of such wagons so as to facilitate discharge and also to provide means for locking said doors to insure safe conveyance of the contents of the wagon.

In accordance with the invention the dumping doors are hinged on both sides of a central longitudinal member in the bottom of the wagon and are connected at their outer edges by links t0 threaded rods working through threaded worm wheels forming nuts mounted on the wagon sides. vThe worm wheels are driven from common shafts and elevate the screwed rods to close the doors or lower them to open the doors for dumping the contents of the wagon. A locking gear for locking certain of the doors simultaneously and all in turn is provided.

In order that the invention may be thoroughly understood and easily carried into practice we have appended hereunto four sheets of explanatory drawings.

Figure l, is a side elevation of a bogie dumping wagon with the invention applied. one half only of the wagon being shown for convenience of illustration but as both halves are identical this will suffice. Fig. 2, is a plan view of Fig. 1. Fig. 3, is an end elevation, the right hand side being shown in section. Fig. 4, is a detail view in section of one of the threaded worm wheels and its worm. Fig. 5, illustrates on a larger scale the locking gear. Fig. 6, is a section on line 6 6 of Fig. 5. Fig. 7, diagrammatically illustrates the arrangement of one of the shafts actuating the locking gear.

The floor of the wagon is broken up into eight doors a (or other suitable number) which hinge at a central longitudinal member b and may be drawn up to'a horizontal position to form a supporting floor for the wagon or lowered to an inclined position for dumping. In the example illustrated the Specification of Letters Patent.

Application filed July 7, 1910.

lifting devices are connected to the center of a member c forming the outer edge 0f each door. The lifting means comprise in each case a link Z connected to a screw rod e. The rod e passes through a correspondingly tapped hole in a worm wheel f suitably mounted in bearings to the side of the wagon. The screw rod chas a limiting washer and nut at its upper end and as the worm wheel f is rotated, it acts upon the rod in the manner of an anchored nut causing the vertical movement of the rod in an upward or downward direction according to the direction of rotation of the wheel. It will be understood that such a screw rod e and wheel f are arranged at each of the doors of the wagon so that upon the rotation of say two of the wheels f the corresponding rods e will be raised or lowered and the same number of doors closedor opened. To rotate the worm wheels longitudinal shafts g carrying worms g1 are employed and these are disposed and arranged to connect up the desired number of doors for simultaneous operation.

In the example illustrated the doors a are connected in pairs and are operated by the side shafts g. The shafts g comprise four lengths each rotated by a hand wheel /z or other suitable means, one pair of doors being connected with each length of shafting. Thus one wheel L and shaft g will open or close two doors and by operation of a wheel 7L at each corner of the wagon all the eight doors are operated.

By reference to Fig. l, one shaft g will be seen extending for half the length of the wagon. This shaft drives by worms two rods e (one is shown on the drawing eX- posed and one cased in) and operates two doors a a represented in dotted lines Fig. 2. The other three shafts g are identical in arrangement and as stated are driven from the corners of the wagon from the wheel z.; at Fig. 2, two shafts and wheels are seen. In this illustrated example gearing is introduced between the hand wheels h and the shafts to give a quicker operation of the doors. Each wheel 7L has a ratchet wheel z' engaged by a pawl 7' which prevents accidental operation of the wheel.

To lock the doors in the closed position and prevent undue strain coming on the closing gear, locking devices are provided which may similarly be operated from hand wheels k at each corner of the wagon. For this purpose shafts Z run along each side of the wagon near the bottom preferably continuing, as in the case of the closing and opening gear, as far as a complete pair of doors as here shown half the length of the wagon. The shafts from each end are arranged in suitable bearings and meet at the center of the wagon and each shaft (four in all) may be rotated by a hand wheel 76 at a corner of the wagon. The outer edge of each door L as previously stated, is strengthened by a suitable section member c and at each end of this member in the case of each door a hook part m is secured. On the shafts Z threaded parts are provided which pass through tapped bushings in wedge blocks n and as the shafts Z are rotated when the doors are closed the wedge blocks are caused to run under the hook pieces and firmly draw the doors up and lock them in the closed position. In the case of each end door one threaded part is provided on the shaft and one wedge block n is used but in the cases where two doors, side by side, have to be secured, oppositely threaded parts are formed on the shafts and two wedge blocks n are arranged to coact therewith. Then as the shafts are rotated in one direction the two blocks at each of such points are moved toward or away from each other thus passing under the hooks or away from them to lock or unfasten the doors as desired. This will be more clearly seen at Figs. 5 and 6 where the wedge blocks n will be seen to have wedge shape projections o which project into the path of the hooks m and as each block is moved by rotation of a shaft Z, with its threaded part on which the tapped body n of the wedge block is disposed, the wedge projection is drawn under the hook m or away fromv it according to the direction of rotation of the shaft Z. The arrangement of these locking blocks at the adjacent edge of two doors will be clearly understood from Fig. 5, where two oppositely threaded parts, two blocks and two hooks are shown.

In the arrangement shown there are two fastenings for each door, that is sixteen in all and each of the four shafts is thus formed with four threaded parts to carry four wedge blocks. The shafts may each be in lengths convenient for manufacture and may be coupled up where desired; such a shaft is shown in Fig. T.

In operation, supposing the wagon to be filled with coal or other material, the doors are of course all closed and locked by the fastenings described, thus forming a hori- Zontal flooring. Zhen it is desired to discharge the contents of the wagon one of the wheels L is rotated to unlock two doors and the corresponding wheel ZL is rotated tov drive the two worm wheels f connected to the particular shaft in a direction causing the lowering of the two rods e, thus opening the doors as shown at Fig. 3, and dump ing the contents. If it is desired to discharge all the contents of the wagon the remaining doors are similarly opened in turn from the controls at the other corners of the wagon.

lNhat we claim then is l. In dumping wagons, the discharge apparatus comprising hinged doors in the floor connected by hinged links to threaded rods which pass through driven nuts secured in bearings on the sides of the wagon, the nuts being driven by means carried by side shafts rotatable from hand wheels or like means.

2. In dumping cars, the combination with a pivotally mounted door, of a threaded rod operatively connected to the free end of said door, a nut for said rod retained against lon gitudinal movement therewith, and means for actuating said nut for opening or closing the said door.

In testimony whereof we atliX our signa Atures in presence of witnesses.
