Application filed April 10, 1914. Serial No.

To all whom it may concern it known that l JAE-{IN F. LIVELY, Men 1 the United lotates, residing at i in the county of London and iennessee have invented new and 'nproi'enients in DoonOperating m of which 'he following is a wecnication.

Th inrention relates to improvements operating mechanism and has par ap 'ilicaticn to a mechanism for ti the doors of hopper cars.

out the present invention, it so to provide an operating or gates of hopper I such may he swung to sd positions and whereby the ecurely and positively locked "ion to prevent the accidental provide a mechcrilieel whereby he cars in ay he swung s and whereby aim to provide a mechforth which will emtures of simplicity ciliw which may he inl ma d at a minimum e);- l which will embody few parts and correlated and arranged as; to re that ,io possibility of derangement to a zz'iinimum. p

ll ith the ahore and other objects in View,

th intention consists in the coi'istruction, 1 matron and arrangement of parts hereinaitcr forth in and falling *ltlllll the "ncture, the side girders and 3 the inloor of the hopper chutesf Closing e of rich chute is a gate pivoted at its movement, as is well known.

sely disposed alining hearings 5 and journaled within the hearings and capable of rotation therein an actuating shaft (I extending transversely of the car and havi the opposite extremities thereof jourlcd in horizontally alining hearings dis- 2d a scent to the opposite sides of the Cal body and secured to the latter in some suitable manner. Fast upon the actuating it 6 and proiecting outwardly therefrom 1 T h ng the outer end thereof 0 provide a f0 ed pivot knuckle the opposite linihs thereof formed with aiming slots 9.- Mounted within the dots t "id capable of sliding movement therein a pin 10 carried by a pivot knuc le disposed between the limbs of the ioz'ked knuckle S and connected with. one nk The opposite end of the is formed with a pivot knuckle 13 between the limbs of a forked knuckle upon ore end of an actuating rod 15. The end l he rod 15 equipped with the nuckle lei: 1s curves. as at 16 to fit "d the shaft (3 while the opposite end xach rod connected through suitable 'ies thereto a. lug 18.

' in practice when the door or gate is open the arm "I and link 12 are coextensive with each other and disposed upon one side of the actuating shaft 6, while the lug 18 extends downwardly. On the other hand, when the shaft is rotated to swing the gate to closed position the arm '2' moves through an arc to the opposite side of the actuating shaft and through the mediiun of the link 12 exerts a pull upon the rod 15 to close the gate. In the initial movement of the arm under the action of tlie'shaft the pin 10 rides from no end of the slots 9 in the forked knuckle to the opposite ends of such slots and the lug 1S enters the space between the limbs of the ZEOlXGd knuckle 1d behind the knuckle 13 on the link while in the continued movement of the arm under the action of the shaft the l8 engages the adjacent knuckle on the link and pulls the actuatmg upper end for pending rem. the center sills l are I the latter as clearly illustrated in Fig. 3.

In the movement of the actuating rod under the action of the lug 18 the curved portion the chute.

16 of the rod fits about the actuatingshaft thereby throwing the pivotalconnection between the link and the actuating rod upon the side of the actuating shaft opposite from the gate and below the center line of such shaft. Thus, the parts are locked against accidental movement and the gate securely held in closed position.

In order to rotate the actuating shaft, I employ, in the present instance, a worm 19 journaled in bearings carried by a bracket 20 suitably fastened to the lower wall of Fixed to the shaft 6 is a worm wheel 21 meshing w'th the worm 19 and inclosed by a casing 22 carried by the bracket 20; Fast to the worm 19 is a crank handle 23 by means of which the worm may be retated to impart motion through the worm wheel 21 to the actuating shaft 6. It will be seen that when the worm is rotated under the action of the crank handle 23 the worm wheel will be revolved with the effect to rotate the actuating shaft 6 so that the operating-and locking mechanism of the door will be actuated as previously described, while the worm wheel being fast upon the shaft and meshing with th worm will act to hold the shaft in any desired position thereby enabling the gate or door to be opened to any extent.

While I have herein shown and described onepreferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims without departing from the spirit of the invention.

I claim:

'1. In a door operating mechanism for hopper cars, an actuating shaft capable of rotation, an arm fast to said shaft and extending outwardly therefrom, a link con in the closedposition of the door whereby the pivotal connection between said link and I rod will be disposed upon the side of the center line of said shaft oppositefthe door.

to lock the door against opening movement, and a lug extending outwardly from said shaft at an angle to said arm and adapted to engage the arm end of said link in the closing of the door to actuate said rod independently of said arm. 3 e

2. In a door operating mechanism for hopper cars, an actuating shaft capable of rotation, an arm fast to said shaft and extending outwardly therefrom and having the outer end thereof formed to provide a forked pivot knuckle, a link having one end thereof equipped with a pivot knuckle lying between the limbs of said first knuckle, a pin and slot connection between said knuckles, a pivot knuckle on the opposite end of said link, said link lying upon said arm when the latter is at one side of said shaft and coextensive withsaid arm when the latter is at the opposite side of the shaft, 1 a door actuating rod having one end thereof of said rod behind the link pivot knuckle therein to actuate said rod independently of the arm.

in testimony whereof I aifix my signature in presence of two witnesses.
