COMBINATION RAILWAY CAR.

Application filed October 27, 1924i. Serial No. 746,139.

To all whom it may concer/n.'

Be it known that l, RAY A. CLAPP, a citizen of the United States, residing at Los Angeles7 in the county of Los Angeles and t State of California, have invented certain new and useful Improvements in Combination Railway Cars, of which the following is a specification.

.This invention relates to railway cars and l@ more particularly to one-man operated cars. One of the objects of the invention is to provide a one-man operated car which may beoperated singly, or as a train when connected to other cars..

Another object is to provide a one-man operated car in which the operator is located in the front right hand corner, and the entrance and exit doors located at the rear ott the operator so that the operator may always see the door steps, thus avoiding step accidents which are common in the present type of one-man cars.

Another object is'to provide a one-man operated car with double, or entrance and exit 25 doors, whereby the car may be rapidly loaded or unloaded, and door accidents avoided. f

A further object is to provide a one-man operated car with an entrance and an exit door, and with adoor operating apparatus actuated by a single handle for opening or closing either door independently, or for opening or closing both doors together.

'With the foregoing and other objects in view the invention consists in the features of construction, combination of elements and arrangement of parts hereinafter described and pointed out in the claims..k

Referringito the drawings which form a part of this speciication:

Figure l is a fragmentary horizontal section or" a one-man-operated car embodying my invention taken `substantially on line 1-1 of Figure 2.

Figure 2 is a fragmentary side elevation or" the car as shown in Figure l.

ligure 3 is a cross sectional view or a portion oi' the step operating apparatus taken on line 3-3 oit Figure 2. l

Figure Il. is a horizontal sectional view of the step operating apparatus taken online 4--4 o Figure 2,

Figure 5 is a side elevation of the door step operating Figures 6, 7 and 8 are horizontal sections 555 of the door and step controller taken on line 66 of Figure 5, showing the controller in positions respectively for opening the entrance door, for opening both the entrance and exit door and for closing both of said doors. l

Figure 9 is a vertical section on line 9-9 of Figure 8.

Figure 10 is a view similar to Figure 3 of a modified form of step and operating @5 apparatus for high cars.

ln the drawings 1 indicates the truck and 2 the body of a passenger car mounted on said truck. ln the Jfront right hand corner of the car body are located'a power control- 7@ ler 3, a door and/step controller 4, a fare box 5 and an operators seat 6. lln the rear left hand corner of the car body, which becomes the front right hand corner when the car travels in a reverse direction the parts 3, 4, 5 and 6 are duplicated. At the rear of each fare box 5 and seat 6 are located an entrance door 7 and step 8 and an exit door 9 and step 10. rlhe location of the parts 3, Ll, 5 and 6 in said corners provides for a continuous aisle il through the car, there being doors l2 in the ends of the car at the ends of said aisle. whereby communication may be established between the ends of the car and the ends of other cars constructed with continuous aisles and end doors, should the car be coupled to said other cars, thus providing a one-man-operated car which may be operated singly or to pull a train.

The entrance door 7 is mounted ,to slide forwardly into open position in the guides 13 inside the side walls of the car body while the exit door 9 is mounted to slide rearwardly into open position in the guides lll inside said side walls. A dividing rail l5 extends within the car body from a point between the doors '1? and 9 and a rail 16 extends inwardly from the rear edge of the exit door 9 whereby .an entrance 17 and an exit i8 are provided in the ear body, leading trom door i9@ 7 and to door 9 respectively.

The operating mechanism for the entrance door 'i' and'step 8 comprises an air cylinder. 20, a piston 2l. in said cylinder, a piston rod. 22, a link 23 connected at one end 'to said, piston rod, a lever Q4 connected at one end to the other end of said linlr and its other end loosely connected to the forward edge of said door2 a link 25 is conneted at one end to the piston` rod 22, a vbell crank 26 is and step arm 28 by the universal joints 29 and respectively'. The cylinder 2O is suspended on a bracket 31 from the ioor 32 of the cai body 2. The forward end of the piston rod 22 is slidable in a bearing 33 suspended from the Ilicor 32. The lever 24 and the bell crank 26 are pivoted at 34 and 35 on a bracket 36 depending from the car floor. The door step Sis pivotally'mounted at 37 on the brackets 38 depending from the car iioor. y l i The operating vmechanism for the exit door 9. and step 10.comprises an air cylinder 40, a piston 41 in said cylinder, a piston'rod 42, a link 43 connected at one end to said piston rod, a lever 44 connected at one end to the other endof said link and at its other end loosely connected to the rear edge of the exit door 9, a link 45 connected at one end to the piston rod 42, abell crank lever 46 connected at one end tothe other end of the link 45, a link 47 connected at one end to the other end of said bell crank and at its other end to an arm 48 projecting rearwardly from the exit step 10. The ends of the link 47 are connected to the bell crank 46 and to the step arm 48 by universal joints 49 and 50 respectively.' The cylinder 40 is suspended from the car loor 32 on a bracket 51. The rear end of the piston rod 42 is slidably mounted in a bearing 52 suspended from the car floor. The lever 44 and the bell crank 46 are pivoted at 53 and 54 respectively on a bracket 55 depending from the car floor. 'The exitl door step 10 is pivoted at 56 on the brackets 38 depending from the car oor.

The door controller 4 comprises a pedestal '60 mounted on the floor of the car and a rotary' valve 61 is pivotally mounted on 'top ef seid pedestal by means of a journal 62 @wl bearing 63. said journal upstanding from the top of the valve and said bearing "eine formed on the end of an arm 64 which evten ds upwardly from the top ofthe pedes- Theppe 67 connects to one en of the cylindei' 20, and the pipe 68v connects to the other f pipe 71 into the pipe 70. The pipe 72 connect's-to the pipe 69, there being a check valve 75 in the pipe 72 to prevent air from entering said pipe from the pipe 69,' but which allows air to pass from pipe 72 into the pipe 69.` A pipe 76 connects the pipes 67 and 71 and a check valve 77 is located in the pipe 76 to prevent air passing therethrough from pipe 67 into pipe 71, but'to allow air to pass from pipe 71' to pipe 67 se A through. pipel 76. A pipe 78 connects the pipes 68 and 72, there being a check valve 79 in the. pipe 78 toprevent air passing through said pipe from pipe 68 to pipe 72 but to allow air to pass through the pipe 78 from pipe 72 to pipe 68. The valve 61 -is provided with a radial port 80 and with an arcuate port 81 which open through the lower side ofthe valve and the port 81 'is provided with an outlet 82' leading into the atmosphere. Local webs 83 and 84 integral with the valve 61 extend across the lower side of the`port 81 flush with the lower face ofthe valve, On the handle 65 is formed a depend- In Figure 10 I have illustrated a modified form of step and operating apparatus suitable for high cars, or cars which require morev than one step, it being understood'that this other step will be applied at both the enis carried on the outward ends of the levers 91. pivoted at 92 to the lower ends of the arms 93 depending from the lower ends of the brackets 38. The link 47 is formed with a depending arm 94 which is connected by a ball joint 95 to an arm 96 extending rearwardly fro-rn one of the levers 91. t Bv means of the link 94arm 96 and levers 91, the step 90 will be let down and folded up' with the step 10,' the step 90 .folding against 'the step v10.

,When .the port 80 communicates-with the pipe 67 the 'pipes 68 to 72 communicated with the vport Y81. Air under pressure passes from pipe 66 through port 80,

through pipe 67 into the forward end of the cylinder 20 Iand forces the piston 21 and trance and exit. In this form of my invention I provide an additional step 90 belowl and outwardly of the-step 10, which step 90 renee?? rod 22 rearwardly, whereupon the entrance door 7 is opened through the medium of the link 23 and lever 24 and the step 8 is lowered through the medium of link 25, bell crank 26, link 27 and arm 28. At the same time air is forced by the piston 21 out of the rear end of the cylinder 20 through the pipe 68, port 81 and out-let 82 into the atmosphere. The check valve 77 prevents any air from assing from pipe 67 through pipes 76 and 1 and out through the valve 61 and check valve 79 prevents air from passing through pipes 7 8 and 72.

To close the door 7 and ,raise the step 8 the valve is turned until the port 80 registers with pipe. 68. Compressed air passes from the pipe 66 through port 80 and pipe 68 into the rear end of the cylinder 20 and forces the piston 21 and rod 22 forwardly, whereupon the door is closed through link 23 and lever 24 and the step .8 is raised through link 25` bell crank 26` link 27 and arm 28. Air is prevented from passi from the pipe 68 into pipes 69 and 72 aii out through the valve by the check valve 7 9. Air in the forward end of the cylinder 20 passes out through the pipe 67, valve port 81 and out-let 82 into the atmosphere.

To open the door 9 and' lower step 10 the valve 61 is turned so that port 80 registers with the pipe 70. Compressed air passes from pipe 66 through port 80 and pipe 70 into the rearward end of the cylinder 40 and forces the piston 41 and rod 42 forwardly, whereupon. the door is opened through the link 43 and lever 44 and the step 1 0 is lowered through link 45, bell crank 46. link 47 and arm 48. Air is prevented from passing from the pipe out through the pipe 71 into the atmosphere by the check valve 74. Air passes out of the rear end of the cylinder through pipe 69, valve port 81 and outlet 82 into the atmosphere,

To close the door 9 and to raise step 10 the valve is turned until the port 8O registers with pipe 69. Compressed air passes from pipe 66 through port 80 and pipe 69 into the, forward end of the cylinder 40 and forces the piston 41 and rod 42 rearwardly, whereupon the door 9 is closed through link 43 and lever 44, and the stepvl() is raised through link 45. bell crank 46. link 47 and arm 48. Air is prevented from passing from pipe. 69 into pipe 72 and out through valve 61 by the check valve 7 5'. Air passes out of the forward end of the cylinder through pipe 70. valve port 81 and outlet 82 into the atmosphere.

To open both doors and lower bot-h steps the valve is turned so that the port 80 registers with the pipe 71 and the webs 83 and 84 cover the upper ends of the pipes 67 and 70 respectively. Compressed air passes from pipe 66 through port 80, pipe 71, pipe 76 and pipe 67 into the forward end of the cylinder 20, and from pipe 71 through pipe 70 into the rear end of the cylinder 40, whereupon the piston 21 and rod 22 are forced rearwardly and the piston 41 and rod 42 are forced forwardly. and the doors 7 and 9 are both opened and the steps 8 and 10 are lowered through the parts and in the manner above described. A ir cannot pass out of the pipes 67 and 70 because they are closed by the valve webs 83 and 84 r spectively. and air cannot escape through the pipes 76 and 71 into the atmosphere because of check valves 77 and 74. Air passes out of the rear end of the cylinder 2O through pipe 68, and valve port 81 and outlet 82` and air passes out of the forward end of the cylinder 40 through pipe 69, valve port 81 and outlet 82.

To close both doors and raise both steps the valve is turned so that the port 80 registers with port 72 and webs 83 and 84 close the upper ends of the pipes 68 and 69 respectively. Compressed air passes from pipe 66 through port 80, pipe. 72. pipe 78 and pipe 68 into the rear end of the cylinder 20.v while air also passes from pipe 72 through pipe 69 into the forward end of the cylinder 40, whereupon the piston 21 and rod 22' are forced forwardly and the piston 41 and rod 42 are forced rearwardly and the doors 7 and 9 are closed and the steps 8 and 10 are raised through the medium of the parts above described. Air cannot escape through pipe 72 to the atmosphere because of the check valves 79 and 75. Air cannotpass out through the pipes 68 and 69 becausethey are closed by the webs 83 and 84 respectively. Air passes out of the forward end of the cylinder' 2() through pipe 67, port 81 and outlet 82. Air passes out of the rear end of the cylinder 40 through the pipe 70 and valve port 81 and outlet 82.
