To all whom it may concern:

Be it known that I, Ranrn G. TAYLOR, a citizen of the United States, residing at Davenport, in the county of Scott and State of the car or the other, is that one is right and the other left, a brief description of one will suffice.

Each hopper has a long sloping bottom 5 Io a, have invented new and useful lm-' portion, a, that inclines toward the center 0 provements in Operating Mechanism for of the car, the lower edge of which termi- Car-Doors, of which the following is a full, nates in a suitable plane mediate the under clear, and exact description. side of the center-sill and the rails, and has -My invention relates to mechanism for short sloping portions 6, that incline in 10 closing and controlling the discharge openopposite directions from the center of length 65 ing of the hoppers of dump-cars, and partoward the ends of the car, whose lower. ticularly, of the convertible liat-bottomed edges terminate about. midway the height of 'freight car and dump-car described in the the center-sill.

The weight and pressure Fig. 1 and drawn to a slightly larger scale. upon this door is considerable when the car Fig. 5 is a slightly enlarged vertical section is loaded, and my improvement relates to through the discharge end of a hopper with the means for regulating and controlling portions of the door broken away to show the closure of this door. To accomplish the coupling between the connecting rod and this, I provide the doors G, (l, of each pair cross-beam. of hoppers with a bracket 42, consisting,

Bettcndort, deceased, hcreinbcfore of each door with the shorter leg uppermost, referred to, the car is shown to possess two its most advanced portion will be almost corresponding alining and opposed hoppers vertical. An I-beam H, of suitable length on each side of the center-sill, that are arhas its ends riveted or otherwise secured to r ranged asto discharge toward the center this advanced portion of the bracket, and of the car below the plane of. the ccnter-sill. transversely passin under the center-sill Two of these hoppers are in the same-transconnects one door with the other door of the verse planes, and as the only difference in the pair.

This, I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings: Figure 1 is a side elevation of a portion of a dump-car embodying my improvements. Fig. 2 is a vertical lonand b, riveted thereto. The portion of the edges of the side-walls between the lower edges of the long and short inclined edges of the hopper are straight apd complete the discharge-opening of said hopper. The

edges of this discharge-opening are suitabl reinforced and it is closed by a door (Jr, which preferably, consists of a single plate of sheet metal sbaped so as to close said ing plates f, f, of a. coupling; each of said 1 :uoaaeeov (a neye extending-there-throug the plane of the web of said I-beam' The screw-threaded ends of a V-shaped yoke or 5 clevis J are extended through the eyes of said. coupling lugs, and secured to the latter by means of nuts I, it. Now, the doors-G are kept closed or partially :or wholly opened, according as desired, by meansof '20 suitable stud ='projecting down from a supporting-plate n secured to the underside of the center-sill. The connecting-rod, M, has an eye at one end that links with clevis J, and is Bifurcated at its other end to enable it to pass both above and below the Wormgear. These bifurcations, 0, 0, have their ends crooked slightly and pivotally connected to a crank-pin, Q, that is secured in and projects on both sides from the wormgea Now, the worm gear, the connectingrod and the doors are so assembledwith relati'on to one another that when the worm gear is turned through the medium of the worm and worm-shaft, the 'door will be pned or closed and held in any position desired without the necessity of a pawl -and ratchet. The friction between the worm and Worm gear is in itself sufiicient to prevent any lost movement. At the same time, 40 the leverage that can be exerted by the Worm and worm gear; is such that one man can have perfect control of the doors.

What I claim and desire to secure by Let ters Patent is:

4a 1. A dump-car, comprising a hopper depending below the plane of the underframe and having a discharge-opening therein, a door for closing said discharge-opening, a I worm, the axis of which is arranged trans- 5C aersely of the car, a horizontally disposed worm-gear' actuated thereby, a connecting- ,rod, pivotally connected to said gearat one end,'and means connecting it to the door at the other end.

2. A dump-car, comprising a hopper d'epending below theplane of'the underframe and having a diScharge-opening, therein, a dgor for closing said discharge-opening, a

worm, the axis of which is arranged trans? versely of the car, a horizontally disposed worm-gear actuated thereby, a connectingrod having'one end bifurcated and pivotally connected to said gear, and means connectling it to the door at the other end.

5. A dump-car comprising'two hoppers arranged one on each side of the center of Width of the car, and depending below the plane of the underframe, and havin discharge-openings therein, a door. for c osing the said opening of each hopper, a transverse member connecting vsaid doors, a. worm whose axis is transverse of'th e car, a horizontally disposed wo'r.- said worm, a connecting-rod disposed between said hoppers, and pivotally connected .to said worm-gear at one end, and a yoke connecting theopposite end of said connecting rod to said transverse member.

' 6, A dump-car comprising two hoppers arranged ig ne on each side of the center of width of the car, and depending below "the plane of the underframe and having discharge-openings therein, a door for closingthe said opening of each hopper, an I-beam con ice-ting said doors, a Worm, whose axis is transverse of the car, a horizontally disposed worm-gcar actuated by said worm, a connecting-rod disposed between said hop pers and pivotally connected to said wormgear at one end, and a coupling clamped to said I-beam between said hoppers, and a, yoke or clevis connecting-said connecting-rod to said coupling.

i 7. A dump-car comprising two hoppers arranged one on each side of the center of Width of the car, and depending below the plahe of the under-frame and having discharge-openings therein, a door for closing the said opening of each hopper, an I-beam gear actuated by IOU gear at one end, and a coupling consisting of two plates clamped to the web of said I-beam mediate said hoppers, and having lugs projecting therefrom, and a yoke, the ends of which eatend through and are sccured in perforations in said lug, and which connects said connecting rod and coupling.

8. A dump-car comprising two hoppers arranged one on each side of the center of width of the car alongside of each other that depend below, and have discharge-openings below the plane of the under-frame of the car, a hanging door for each of said discharge openings, a bracket secured to and projecting from each of said doors, a trans verse I-beam having its ends secured to said brackets, a transversely arranged worm, a horizontally disposed Worm-gear actuated thereby, and a connecting-rod for imparting motion from said worm-gear to said I-beams and doors.

9. A dump-car comprising two hoppers arranged one on each side of the center of width of the car alongside of each other that depend below, and have discharge-openings below the plane of the underframe of the car, a hanging door for each of said discharge-openings, a bracket secured to and projecting from each of said doors, a transverse I-beam having its ends secured to said brackets, a transversely arranged worm, a horizontally disposed worm-gear actuated thereby, a coupling secured to said I-beam mediate said hoppers, a yoke, or clcvis, the ends of which are secured to coupling, and connecting-rod connecting said worm-gear and yoke.

In witness whereof I have hereunto set my hand this 18th day of October, 1910.
