Specification of L'etters'Patent- P t t d D .24

Application filed July 3, 1911; Serial No. 638,702.

To all whomit may concern: I

Be it known, that I, J AMEsMcCUrcHEoX CoLmiAX, residentof 356 Olivier avenue, in the city ofVestmount, in the Provinceof Quebec. in the Dominion, of Canada, a c1t1- zen of the United States offll-lmerica, have invented certain new and useful Improve,

ments in Dump-Car Construction; and I do hereby declare that the following is a full,

clear, and exact description-of the same.

The invention relates to improvements in i v dump car construction, as described in the present specification and. illustrated in the accompanying drawings that form part of the'sam-e. H I The invention consists essentially in the novelconstruction and arrangement of the doors'closing-the dump openings, whereby.

the joints are'absolutely tight and the-door readily operated. I

The objects of the invention are to 1mpro've .the-conditionsln regard to cars used for carrying grainand the like in which the contentsof. the canare shot out of a chute, and-particularly 'to preventleakage through the .chi1teopen1ngswhile the car istravel- Further objects are to facilitate the ,op--' eration of thechute doors on arrivalat the elevators, and generally-ftoprovide a cheap,

simple and durable form of dump car door. In-the drawings, Figu-re l isa. longitudinal-Isecjtionalview of a 'c hute, show i ng the 5 sliding door and operating mechanism. Fig.

2 is'a'n enlarged detail view of the door,

' showing the joints. Fig. 3 is a cross section b detail ofthe operating mec'hanism. Fig. 4 is 3 "responding parts in eacha sectional detail of the dischar e end" of the chute with the door remove 'Fig. 5 is a vertical sectionalview taken on the line C, D, in Fig. 4.- ig. 6 is a vertical sec-,. t'ional View taken on the line A, B, in Fig."

4. Fig. 7 is an underside perspective detail view of the door and operating mechanism detached, withparts broken away. I :Like numerals of reference indicate corfigureg. Referring to the drawings, 1 is thel'chute under the body 2 of the car, said chute terminating in the blank wall-3 at the lower end and having the dump door openlng 4, in-the bot-tonrthereof .atthe lower end, said dump door opening being the width of said bottom. 1

. 5 is an outturnediflange at the lower end v of the, blank wall out-side face of the door the upper end of the arm 15,

18, the latter'is operate upper end of the arm around and 'draws it and parallelwith the flange o socket.

7 are outturned flanges from the 'sidesof the chute at the door opening at; '8 are in- 6 is an intu'rned flange distanced from forming a v turned fianges'at the s ides "of the chute distanccdfrom and parallel to the flanges 7,;both flanges b'ein rigid with said sides. 9 is an out-turned ange at the upper side of. said door opening, rigid with the outside surface of the bott om'of the chute.

10 is a slide door, having on the lower side. thereof, the flanges 12 on'the sides and onthe lower end respectively and substantially parallel with the surfaceof said door and terminating substantially flush with the edge thereof, so that said door will slide in and 6.

the sockets formed'by the flanges 7 and 8 5 and into the socket formedby the flangesii '75 13 is aninturned'flange on'the inside of .the door at the upper end thereof and par" allel with theinside face ofthe door and adapted to slide into-the socket formed by pocketjoint" at the" upp lower end. Y I. 14 is' a' bracket, centrally secured to the IO,',extending p'ar allel with the said outside face. 15 is an arm pivotally secured between the ,bracket' 14 and the outside .face of'sa-id door 10 by the pivot pin 16, said arm being off-set ,at

17 and extending upwardly parallel/with the bottom of the chute.

theoutturned flange 9,'thereby providinga erfend of-the door, the same as-the pocket oints atthe sides and" .1-8 is.- a gear of worm wheel form and pivotally secured toward the edge thereofto said gear being journaled on the bearing 19, said bearing being rigidly secured to the bottom of the chute or bottom of the car as may be most convenient. I

20 is a worm coacting with the gear 18 ingssupp'orted 'by the bracket 22 and extending across to the sides of'the car, there being op'eratedby the crank i It will be thus'seen that a very constructionis provided, particularly for sliding doors covering turned and thus coacting with the said gear and mounted onor forming part ofthe. shaft 21, said shaft being j'ournaled in bear--' complete dump openings; a

by means ofthe crank 23, the worm 20 is I 110, which 'swing s't-he farther up the chute, thus the door 10 1s slid upwardly 1n the shdeways formed by '.the flanges 7 and S.

In closing the door, the crank is turned 1n the reverse direction and practically the same operation occurs, thatvis to say, the door slides along, though downwardly, and

when driven to the home position, the double. set of flanges form pocket joints through which even the finest granulated cargo cannot leak out.

What I claim asmy invention is: 1. In car construction, a chute secured to the body of the car and terminating in a blank wall at the end thereof and having a dump opening through the bottom thereof at the lower end, flanges rigidly secured around said opening and forming, with said chute walls, surrounding pockets to said door opening, a door of double plate formation at theedges thereof forming pockets completely therearo'und, and means for operating said door in and into the aforesaid pockets surrounding the chute opening.

2. In car construction, a chute secured to,

the body of the car having a blank wall at the lower end thereof and a dump opening end of said dump opening, a door having at the lowerend a double plate formation coacting with the double plate formation at the lower end of said blank wall in efl'ecting the joint, and double plate formations on the sides thereof coacting with the dotibl plate formations on the sides ofiithe dump opening and an inturned double plate formation atthe upper endthereof co-acting with the outturned double plate formation at the upper end of the chute opening, and means forvoperatlng said door.

3-. In a car construction, a chute having a blank wall, a dump-opening in said chute, a

door having at its lower end a double plate formation coacting with a double plate formationat the lower end of said blank wall to form a joint and a double plate formation on the sides thereof coacting with the double plate formations on the sides of the dump opening to form a joint and an intur-ned double plate form: n at the upper end of said door coacting with an outturned double-plate formationat the upper end of said chute opening, and means for operating said door.

: Signed at the city of Montreal, Province of Quebec, Canada, this twelfth. day of June, 1911.
