PLATFORM AND-GATE ssnnnmr.v

Application filed October 19, 1925. Serial No. 63,484.

lThe invention relates to mechanism for "to engage the respective side'gates and trap "doors, the devices comprising said means being mounted upon av support commonto 15 all of them, all of the'assemb'led parts being held{ by the support in fixed operating rela- "tion to each other andthe platform gates and trap doors.

A further object is to so interlock the 2 platform railing si'd'egates with aholding 7 device rigidly secured tothe'car that the gate proper will operateto connect the ho'lding devices onthe' car body to thefixed portionsof the railing.

25 lhe foregoing-and other objects'are -attained by themechanismillustrated in the accompanying drawings, in which-:

Fig. 1 isa plan ofa portion of an'observa tion car platform showing the relation of trap door and gate to the holding device on the carbody;

I Fig; 2 is a vertical section through'the platform taken, on line 22"-'of- Fig. 1 looking inthe direction indicated by the-arrows; Fig. 8 is a" broken frontelevationalview of theholdingdevi'ce on an enlarged scale showingthe. relation of the gate interlocking portion and latch to the" trapdoor catch and grab handle i Fig. 4a is a side 'eleva tional view thereof;

Fig. 5 is a bottom plan ofthe connecting shoe ofthe holding devicesy v v Fig. 6' is a horizontal sectional View taken on line 6-6of"Fig., 3 looking-in the direc- 45. tion -indicatedby the arrowspand Fig. 7 is. a'horizontal sectional? view through the connecting cap pieceor the holding devices taken onaline" 7 7 "of Fig. 3 looking in the-"direction indicated the In said drawings,- 10' indicates" thebo dy of a: car equipped with the invention, .11 the platform, and12; the railing; enclosing the as illustrated inthedrawin'g containing the the operator.

ward movement of the trap 'checked'upon contactthereof with lower'rail 90 and perforated as at 31? toreceivefa pluraling same'tethe 'carbody. Thee p The-railing is made up of the fixed portions 13.securedto pillars 14 supported in buifer'sill 15 ofthe car under- .frame, and'the horizontally swinging side 1 gate portions 1'6 pivotally securedby hinges 17 to fixed portions 13-ofthe2railing- Trap doors 18 a're. pivotally mounted at right angles to the gates on" brackets 19' secured to the end'sill 20 of the car underframe in position to be engaged" by the catch 'when raised to the, open position indicatedin *dotted"lines in Fig. 2 as will hereinafter appear. The trapdoorsare 'hel'd in their closed position at the platform level by means of any 'a'p'provedform of lock 21, such usual slidi ng bolt 22* normally'held above 7 the free edge of the-trap door 18" with bolt retracting shaft 23*extending upwardly therefrom and fitted with operating handle- 24 in position to be conveniently reached by 'Theside gate 16, constituting the movable portion of the platform railing, swings, in a horizontal plane above the trapdoor 18. When inits closed position the gate'is held parallel to theouter edge of; the'trap door with itshinge portionY17 at the free-edge of j the trap door and with the'free edge of the gate at the pivoted side of the trap door. Thus positioned the gate will lie in the path of movement of the trap door 18 to limit iany premature rising of the trap door resulting from the failure or unauthorized manipulation "of the 'trap *door lock 21,f furthe'r updoor being 26 of the gate 16. It will be obvious that until the gate is' swung inwardly beyond 'the "free e'dge'of the trap door the "trapdoor will be held down-to prevent accidental injurv'to persons oocupyingtheplatform. 9

e To insure'stability in .the platformraiiling as a whole, the gates 16 are interlockedwith t-he body of thcarthroughthe medium oi holding devices 27 "constituting the cjon-' necting cap piece of the necting shoe piecef28. I

The oappiece 27 is"provided with securin'g flanges29' and 30shap'e'd tothecontour of the"contiguous body portion ofthe" oar groupya'nd the Lconity of machine screws or thelike for attack 1 new 7 also equipped witha may shaped to provide a coupling 33 designed to interlock with a complemental coupling 34 on gate 16. The couplings 33 and 34 are held in intimate interlocking engagement by means of a retaining latch 35' pivotally mounted at 36 on cap piece 27 and adapted to engage a wedging face 37 on gate coupling 34. Latch 35 is normally held against "hold portion 43 as indicated in Fig. 4 of the drawings. Interlocking with the lower end of hand-hold 43 is a similar hand-hold extension 44 projecting laterally and upwardly from the shoe piece 28. The shoe piece carries a flange 45 which, like flanges 30 and.

31 of cap piece 27, isprovided with countersunk holes 46 to receive a sufficient num ber ofmachine screws for the'proper fastening of the shoe to the car body. The

, shoe piece is notched out as at 47 to receive Cal tongue 48.0n the lower rail 26 of gate 16 as shown in Fig.2.

The cap and shoe pieces 27-28 are connected by a post section 49 having at its upper end a swelled pocket portion 50 containing the plunger mechanism of trap door catch 25. The plunger mechanism consists of the plunger rod 51 seated upon spring 52 and fitted with head 53. Plunger pocket 50 is covered and the mechanism protected by lid plate 54 secured to the post 49 preferably by screws 55, the plate functioning also asa wear plate for the free edge of the trap door 18 when raised to open position indicated in dotted lines in Fig. 2. The connecting post 49 may also be provided with openings 56 to'receive additional fastening means should that be found necessary. 1

The gatelG is released bygraspinghandle 57 of retaining latch 35 and pressing the latch inwardly against the spring 38' and past the wedging face 37 on the gate until the latch assumes the position indicated in dotted lines in Fig. 7 whereupon-the gate will be free to swing past the latch to its open position beyond the free edge of the trap door. Bolt 22 of trap door lock 21' is then retracted and the trap door raised to its open position against wear plate 54 on the plunger mechanism pocket 50 in which position the trap door will be held by latch 25 engaging the underface of the trap door at latch opening 58.

To close the gate the trap door is released.

from its open latched position by. depressing plunger rod 51 against spring 52 thereby disengaging latch 25 from the trap door. The trap door is forced to its closed position in the platform and held there by lock bolt 22, after which the gate 16 is=swung to closed position past the retrac'tile latch 35 1. In a platform and gate assembly, thecombination comprising a platform railing having horizontally swinging side gate portions, platform trap doors pivotally mounted on the car body at right angles to. saidgates, and connected holding devices secured to the car body at the free ends of said gate portions and in assembled relation to each other and said gates and trap doors.

2. In a platform and gate assembly, a

platform railing having horizontally sw nging side gate portions, connected holding devices connectingsaid gates to the car body, coupling portions on said gates adapted for interlocking engagement with saidholding devices, and gate latching means.

3. In, a platform and gate assembly, a platform railing having swingingside gate portions, holding devices connecting said gates to the car body, complemental couplings on said gates and devices, and gate latching means on said holding devices adapted to hold said couplings in interlook in g engagement.

4. In a railway car platform and gate assembly comprising a platform railing having pivoted side gate portions,'holding devices connecting said gates to the car body and including upper and lower securing pieces, and bars connecting said pieces, one of said bars constituting a hand-hold in said assembly.

5. In a platform-and gate assembly, the combination comprising a platform railing having horizontally swinging connecting 3 side gate portions, trap doorsv pivoted to the car body adjacent the free ends of said gates, connected holding: devices securing said gates to the car body, coupling portions formed on said gates and holding devices,

and locking means on said devices for holding said trap doors raised.

6. In a platform and gate assembly, the

combination comprising a platform railing having horizontally swinging side gate portions, platform trap doors pivotally mounted emme on the car body adjacent the free ends of said gates, holding devices at the free ends of said gates, and locking means on said devices for holding said trap doors raised.

7. In a platform and gate assembly, the

combination comprising horizontally sWing-' ing side gate portions,'trap doors pivotally mounted on the car body at right angles to and adjacent the free ends of said gates,
