To all whom t Amay concern.'

Be it known that l, HERBERT R. KEITH Lm?, a citizen of the United States, and resident of Michigan City, county of Laporte, and State of Indiana, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

rllhe invention relates to dump cars of the hoppery type, in which the doors for retaining the lading are arranged transversely of the car and are hinged to a beam centrallyV crossing the. hopper opening.- This type of v car 1s more commonly used for carrymg ore,

' and the lading is`discharged between the portions being removed gl rails of the vtrack on which the car runs.-

. The objects of theinvention are to generally improve oncars of this type,\ and more specifically toprovide means for deliecting the material' inwardly as itv falls land to provide improved means for operating and locking the doors.

A practical embodiment of the invention is hereinafter described, and -is illustrated in the accompanying drawings, in which-4 Figure l is a side elevation of the car,`f"

partly in section;

Fig. 2 is a plan view Fig. 3 is a sectional view on the of Fig. 1;

Fig. f1 is a detail of the car showin the mounting of the doors and the contro ling mechanism therefor; and

Fig. 5 is a view in perspective of a gear of the device.

The car frame comprises a pair of side sills 10, 11, at each side, and a pair of short center sills 12, 13, at each end of the car and` terminating at the hopper, these various sills being, of course, suitably con# 7 nected by means of end sills and such transverse beams as maybe essential to strength.

The hopper com rises'suitable side plates or walls, as 1d, an transverse slope sheets as 15, rivetedv together and suitabl sup- 'p ported by upper framework. Prefera ly the d@ slope sheets 15 have their side portions 1 6, 17, upwardly inclined to facilitate free dise f charge of the lading.v An end or door plate as 18, covers each pair of center sills an the'end portions of the side sills,.and ex# tends from the end of the car frame tonthe slope sheet 15 of the hopper, to which 1t 1s of the car, some line 3-3 l mounted 'upon the bolt 35.

'hopper opening, and is secured to the inner side sills 11, this beam being preferably covered by a shield 21, which, as shown, 1s substantially tl-shape in cross-section.

The doors 22, 23, are hinged to the beam, as shown at 24. rl`hese doors close against the lower margins of the slope sheets 15. llnwardly inclined deiecting plates, as 27, are secured to and form extensions of the slope sheets 15, extending downwardly to and being secured to a pair of short transverse bars 25, supported by a pair of hangers, as 26, pendent from the side of the car, and a rod 26a hooked over the beam.

rlFhe doors 22, 23, are independently controlled, and as the controlling mechanism is the same for both one set only need be de'- scribed. Furthermore, the operating mechanism is duplicated at each' side of the car,

" back of the plane of the slope sheet, a short shaft 28 is journaled in suitableboxes4 29, 30,

`lattached to the adjacent faces of the sills. -Up'o'n this shaft 28 is lixed a spur gear 31, which may be segmental.

rlhis wheel is provided with a crank arm carrying a wrist pin 32, which is connected by means of a rigid bent link 33 with the adjacent door, being edge. When the door is closed, as in the solid lines position of Fig. 4, the wrist pin 32 has been carried slightly beyond a line passing through the centers of the shaft 28 and the pivot on the door to which'the linlr 33 is connected, the elbow of the link restin upon the/hub of the wheel, or upon the sha 28 as shown. p

ln order to insure the tight closing of the door the connection with the actuating wheel 31 is made adjustable. rlhis is accomplished by means of an-extensible crank arm. rlilie wheel is provided with a bon-shaped ca "e 3d, through which extends a threaded bo t 35, the outer end of which is in the form of an eye and holds the wrist pin 3.2. Within the cage 34: is housed an adjusting nut 33, B suitable 'manipulation of this nut the bo t may be extended or retracted to adjustment` provide a' proper atA titl

attached thereto near its swingingI ldd The two gear wheels 31 coperating with each door are actuated by means of pinions 38, 39, fixed upon a shaft journaled in the several side sills of the car frame and eX- tending at each end beyond the outer sill, the projecting ends of the shaft being squaied for engagement by an operating wrench or removable crank handle, not shown. A retaining pawl 41, pivotally attached to the side sills, coperates with a ratchetwheel 42 in fixed relation with each of the pinions 38, 39. A locking dog 43, pivoted to one of the side sills, may be thrown into engagement4 with a should-er 44 formed on the pawl 41, eectually preventing the disengagement of this pawl, from its associated ratchet wheel.

By turning the shaft 40 to the right (Fig. 4) by means of a suitable wrench or crank, the door is'closed and the wrist pin 32 carried a little past the center in order that the weiglitpf. the lading may be borne by the shafts 28. 'Ihe pawl 41 prevents accidental opening, and the dog 43 securely locksthe pawl against being thrown back by jarring.

To open the doors it is necessary to manually turn the wheel 31 to throw the wrist pin 32 past the center, whereupon the weight of the lading will become effect-ive. In order to prevent injury to the operator in this releasing action, a pair of segmental pinions 45 are fixed upon a second cross shaft 46 and engage the teeth of the pinion 38. The shaft 46 eXtends beyond the outer side sills and has its ends squared for engagement by a wrench or hand crank. The

' pinions 45 are provided with just enough teeth to carry the crank pin past center and disengage from the pinions 38 as the weight of the lading becomes effective to open the doors.

The pawl 41 is automatically raised by a cam 47 formed on and oiset from the teeth of the pinion 45 and cooperating with a shoulder 48 on the pawl. The doors are provided with side wings or plates 3?, which prevent the escape of the discharging materia] laterally.
