DOOR MECHANISM..

i Specification of Letters Patent.

Patented Jan. 4,1910.

Application filed December `16, 1908. Serial No. 46?",839.

To all whom it may concern:

Be it known4 that I, JOHN PEAnsoN, a citizen ot' the United States, residing'at Chicago, in the county ot Cook and State of illinois, have inventedl certain new and useful'Improvementsl in Door Mechanism, of which the following is a description.- y

My invention belongs to that class of devices known as door operating and controlling mechanism, and-more particularly a dump Y-ar door mechanism, and has for lits objects the production of a simple, e'tl'icient and satisfactory device of the kind described. l v

While in the drawings thedevice is shown as appliedto car construction, itis obvious that it may be used whereverit may be found applicable.

To this end my invention consists in the novel construction, arrangen'xelit and combination of parts herein -shown and described and more particularly pointed out in the claims.

In the drawings wherein like reference` characters indicate like or corresponding parts, Figure .1 1s a cross' sectional view ot a portion of a ear with my preterred mechanism applied thereon, one door closed and' one door opened. Fig. 2 is a top elevation of a portion of the car showing several doors, Fig. 3 is at'ront elevation ot' one of the preferred forms of door locking and supporting members, Fig. 4 is an enlarged side elevation of the same, Fig. 5 is an enlarged side elevation of the same with the 'parts in dif- `ferent positions, and Fig. 6 is-a view showing simple means 'for ope 'ating Winding shaft.

yReferring to the drawings the can is not shown complete in all its details as this i'orms no part of my invention, it being understood that my construction may be used on any form of car to which it is applicable.

VAs shown the car is provided with a plurality of dump doors 5-'5-011 each side thereof, the same being hinged longitudinally the car and arranged to ,torni the bottom of the ear when closed.

Referring particularlyT to Fig". 1, beams 1 1 and #1f-4 are prete ably provided and arranged lengthwise at the center and of .the car forming a part ot' the car body which is supported upon the car trucks (not shown)' in, any suitable way. The doors 5 as shown in this figure are arranged on each side of the center beams 1 and pivotally supand supporting member 13 which is sides ported bymeans of brackets carried by the beam A. floor 3 of any suitable material may be arranged as shown if desired. The doors o may be secured to the body of the car in any suitable way, straps 7 and pins (3' giving a simple and convenient construction. 'lhe outer or free edges of the doors are supported 'by suitable locking and supporting means carried by the car, preferably by the bean'is 1 1. Referring to Fig. 1 the left hand door 5 is closed while the right hand door is open or in a dumping position..

ln the preferred construction as inexitioned the door is supported and 'controlled by a suitable member and controlling and locking means provided for said member. The supporting means comprises a locking Ivotally secured by a pin or its equiva ent to a suitable bracket 16 carried by the beam 4. There are preferably a plurahty of 1ocking members tor each door, two being shown in the drawings, a description of one and its operation suttieing for both it being understood that they operate .at the same time.

The supporting or locking member 13 is provided with-a hooked .end 14 or its equivalent at which is )rcferably pivotally secured a lilik 17 on eacli side thereof, the links be# ing connected by a pin20 or the equivalent. 0n each side ot the beams 1-1 is arranged what may be termed a winding shaft. 8v the same being suitably supported from the car body and providedl wlth drums 9 or the equivalent. y A chain 10 or an equivalent flexible member connects thelinks 17 with the -.drun1 9, the chain being suitably secured to the drum or winding shaft and tothe links 17- by means of the link 19 orthel equivalent. V The door 5 is preferably provided with a roll 11 or its equi Yalcnt upon the free edge at each of the .locking members 13,'.the same being supported or secured to the doorlby the brackets 19.-12 or equivalent means for the purpose. .fk/locking pawl Q2 maybe provided on the supporting member, 13 at .'if desired, the purpose of the same being more fully explained hereafter.

et'erring to Fig. 4 in which the door isl shown in its closed position the chain 10 is under a strain, that 1s, wound on the drum 9 so that the links 1T and. supporting member 13 are in- -substantially the position shown,

the roll11 resting on the hooked end 14 of the supporting memberl so that theweight of the door is carried by the members 13 andvr the beam l1, the links 17 and chains 10 act- .ing'as controlling means and preventing the supporting member 13 from swinging out.

It might be noted that the center of the roll 11is slightly outside the center of the pin 18. When it is desired to open-the doors the locking pawls are turned up intovthe position shown in Fig. 5, and the shaft 8 then turned so as to slack or unwind the into the positions shown 4on the right in Fig.`

l, there being sliding or rollcontact ybetween the roll 11 on the free? edge of the door and the chain l0 which supports the-door when not supported by the members 18. To close the doors the shaft 8 is rotated in a direction to .strain or wind the chain 10 upon the drum 9 so that the doors are lifted thereby the'links 17l substantiallylifting the rolls l1 upon. 'the hooked end 14 of the members 13 when it rea'chesthat point so that the parts assume their positions to support the doors as shown inFig. 4. It might be mentioned that the links may be proportioned to give any desired leverage in lifting the rolls upon the supporting members or that is throwing 'them into -operative positions. .he locking pawls 22 pivotallyA secured to the members 13 by means of a pin 23 or theequivalent are arranged to lock the links y1,7 into the position show n in F ig. 4, the shoulder 26 (see Fig. 3) .coperating withv the link should vthe lchainbrea'k and -so prevent the doors from opening. The supporting member 13 is preferably provided with an extended portion 21 which is adapted to throw A the locking pawl 22 down during the operi ation of lowering the door after it has been turned up as heretofore mentioned so that the locking pawls are automatically reset and are alwaysv in operative position when the doors are closed. 1f desired `the doors may be provided with auxiliary rolls 211 car-l ried by the brackets 25 which are adapted to coperatel with chain 10. 4 Any suitable means may be employed to operate or rotate the shaft 8 a very simple arrangement being shown in Fig. 6. Referring to this figurea ratchet 27 is arranged on the end of the shaft and operated by means ofa lever 28 and pawl 29, -a pawl 30 preventmg the shaft from slipping back when a newi'engagement is made between pawl 29 and the ratchet 27.

It is thus seen' that in ythe construction shown there is substantially no weight of the door on the chains or straining Lof the chains casses -except -while the door is being opened or closed, nor is the door in its closed position supported by the chain or winding shaft but directly from the fralne of the car. It is obvious that there may be any number of doors and that they may be 'arranged on the car body in any suitable way, that is transversely or longitudinally or that the construction of the car body and doors may be such as is desired.

' Having thus described my invention it is lobvious that various immaterial modifications may be made in the construction` and combination of parts herein shown and described without departing from the spirit of my invention, hence I do vnot wish to be understood as limiting myself to the exact construction shown 'and described.
