FEICEH FRANK H. .l-OPKINS.y 0F MONTREAL, QUEBEC, CANADA.

BALWAY CAB,

Application filed August 12, 1921.

To all whom t may concern: o.

Be it known that l, FRANK H. HOPKINS, of the city vof .Montreah Province of Quebec, Dominion of Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in Railway Cars; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention is described in relation. to general service cars and has for its object to provide means for .closing a relatively large discharge opening, such means being adapted for manipulation to close the opening by direct manual effort, that is to say by a trainman simply employing his own strength without extraneous means to lift the door to its closed position. To this end I provide a relatively large door opening and a plurality of relatively small door sections adapted to be lifted by the trainman to closed position without the necessity of the usual complicated and costly mechanisms heretofore required to develop sufficient power to close the door.

For -full comprehension, however, of my invention reference must be had to the accompanying drawings in which similar reference characters indicate the same part and wherein: y

Figure 1 is a fragmentary plan view of a floor of a general service car provided with my invention;

Figure 2 being a sectional view taken lon line 2-2 Figure 1; u

Figure 3 is a sectional view taken on line 3 3 Figure 1, and illustrating one door member dropped to discharge position and a companion door member in raised position before being locked;

Figure 4 illustrates one of the doors in plan view on a larger scale;

Figures 5 and 6 are similar views illustrating a side and end;

Figures 7 and 8 are detail perspective views of the hinge; and

Figure 9 is a detail transverse sectional view of the overlapping edges of doors the section being taken on line 9F@ Figure 4.

The body 10 of the car and its sub-structure 12 are in the main of usual construction, the doors beinghinged to the center sill 13 and supported in raised and dropped position by the transverse girders 14 upon which suitable devices for the purpose are carried,

a chain operated bar 15 and movable clips 150 supporting the doors in raised position; and a Z-bar`16 carried by a bracket 1'? on one of the cross-girders receiving the shoclr of the door when dropped and supporting it in position to discharge the lading.

According to my invention the door opening of this general service car is closed by a plurality of door sections instead of'asv heretofore by a single door. l have illustrated an embodiment in which a pair `of door members are used for each opening one of which l have marked Door 1 and the other Door 2. These door sections are hinged at the same ends to the center still by hinge-pins 18 supported in brackets 19 riveted to the center sill, the doors being hinged upon these pins which are disposed in axial alignment. The hinge I prefer to use is built up of hinged plates 20 and angles 21 riveted respectively to the vertical flanges 22 of longitudinal door reinforcing angle bars and transverse reinforcingangle bars 23. The longitudinal reinforcing angle bars 25 at the left and right hand sides of the door 1 and door 2 respectively are disposed in juxtaposition with the edges of the door while the longitudinal bar 26 is disposed a short distance inwardly from the left edge of door 2 in order to present a flange 27 to overlap the contiguous edge of door 1. This particular arrangement of reinforcing angle bars not only stiifens the doors in their longitudinal direction but also produces in the edge of door 1 a direct support for the flange 27 as shown clearly in Figure 9, thus effecting a tight joint at this point.

rlhis construction also, presents an unobstructed door opening.

To discharge a car equipped with my invention the supporting bar 15 is displaced in the usual manner thus allowing the doors to drop onto the support 16. When the car has been discharged the door members may be readily Closed by the operator by simply lifting them successively to place, door 2 being lifted first and then door 1. The clips 150 are each in turn projected over the bar 15 to hold up the doors while the bar is shifted to supporting position.

A car equipped with my invention has the advantage of expeditious operation, the

it will be observed,

`'door sections provided they are constructed to properly co-iict as described7 Without de.- parting' from the'spirit or my invention.

TWhatI claim is as follows:

l. In rar for the purpose set itorth they bottom ot' which has a. discharge opening e plurality ot reacting' door sections and means torhinginn the same at one and the same side of the door opening; With the.

of the hinges in alignment, and displaceable means for supporting the door sections in raised position.

In a car for the purpose set forth the bottom ot which hss a discharge openi g, a plurality of coacting door sections and means for hingingg' the same Vat one. and the same side of the door opening, and' displaceable meansifor supportingthe door sections in :raised position.

In `a carftor'thc purpose set iortli the bottom of which' has a discharge opening, a plurality ot reacting` door sections .and means for hinging hte same at one and the suine side ott the door opening, the contiguous edges `ofthe` said door sections having reinforcing men'ibers. one of kWhich is dis-l posed ;inwardly from the edge to present a.

flange to overlap the edge-.of the otherdoor section, andv displaceeble means for supporting'the door sections in raised position.

4:. In a car'for the purpose set forth the bottom ot which has .ii-discharge opening, a plurality otl coacting doorsections and means .for hinging the same at vone-and the same side of the door-opening', the contigu-y ous/edges of the said door sections having reinforcing' members, one of which isdisposed inwardly trom the edge to present a Hanne to overlap the edge oi the other door se: tion and the seid other door section having' a reinforcement memberin juxtaposition with its overlapped edge and displaceable means for supporting the door sections in raised position.

In a car for the purpose set forth the bottom of which has a discharge opening', e. plurality oi" concting); door sections and means for hing-ing the same at one and the saine side ot the door opening' each door heving longitudinal and transverse reinforcement n'iein'bers upon its underside, .and the. said hinging means consisting' of `hingepia rigidly secured to'tlie longitudinal reintorceinent members and angle. hingeplates disposed in juxtaposition with the said hino'edplates and rigidly securedito the trunsreY :e reinforcement means. brackets i fgjidlj. secured tothe center sill hinge pins disposed in alignment through the brackets L ^l hinges ofthe door sections?` and disp .able means ilor supporting the doorsections in raised position substantially as described.

(i. In a dump car, the combination of an unobstructed door opening, ot' a plurality of doors hinged at the sameside ot such door openinm to close said door opening', and ineens or opening'- and-closinsc` lsuch doors.

ff. In a dump Car, the combination ot a door open ot n plurality of doors hinged at the saine side'of such door opening, to close said door opening', seid ldoors heini); adapted to be closed independently.

8. 'In :i dump car, .the combination of a door opeuingota plurality ot doors closing; such openingA and adapted 4to be" closed'independently ot each other, and means for opening` the doors simultaneously.
