The carrier 1 is the same carrier as shown in. the above noted patents and has the same lid 2 hinged thereto. The cylinder 1 is mounted in the cab of a locomotive by means of a bar 3 and hangers 4:. are jointed at 5' to bars 5 and hinged brackets 6 are attached to the side of the cab for the jointed hangers. The bar 3 is slidable in bearings 7 which are attached to the side of the cab. The carrier is supported on the bar 3 by means of the jointed hangers L and bars 5. The carrier has lugs S and the bars 5 engage annular grooves in the outer ends of the lugs 8. The weight of the carrier is thus carried by the bar 3 and the lugs 8 by means of the hangers 4L and bars 5. The carrier is braced in its normal position by brackets 9 which are attached to the side of the cab and by sockets 10 which are rigid with the carrier 1. WVhen the carrier is being mounted the sockets 10 are run on the brackets 9. I

Means are provided forlocking the carrier against accidental displacement. The bar 3 has one end curved upwardly and then back to engage the bearing bracket7 on that side, the end 11 engaging the bracket 7. A locking bar or bracket 12 is attached to the bar 3. A look 13 is formed integral with one of the hinges of the lid 2. When the lid is raised, the lock 13 engages the shoulder 1d and locks the bar 3 against movement so The hangers 4 that the bar 3 is held in the arms or hangers 4 so that the carrier cannot fall. When the lid 2 is thrown down, the lock 13 being rigid with the lid 2 will strike the shoulder 15 and thus knock the bar 3 endwise and withdraw the ends from the bearings 7. This will release the hangers 4 and leave nothing to support the carrier. The carrier will drop by gravity. Something is needed to thrust the carrier 1 out of the cab. Lugs 16 are rigid with the carrier. Hinged bars 17 are provided with hooks 18 which are adapted to engage the lugs 16 as the carrier 1 descends. The bars 17 are hinged to the side of the cab and these bars are connected together for action by a rod or bar 19 which is pivotally connected to both bars. The advantage of having two bars 17 on each side is that these bars will hold the carrier in a vertical position while it is being swung out of the cab. The carrier will be delivered out at the side of the railway track by the bars 17. The bars 17 are prevented from going too far backward by guards 20. The mechanism for holding the lid 2 open and for guiding the seat down within the carrier is set forth in Patent Number 1,147,464, above noted. The seat 21 is mounted on a platform 22 which is attached to the back frame pieces 23 and made rigid therewith by braces 24. The seat is locked in its normal position by devices carried by the platform 22. A locking lever 25 is fulcrumed on the bottom of the platform 22. A locking bolt 26 is operatively connected to the lever 25 by a link bar 27 which is pivotally connected to the lever 25 and to the bolt 26. A socket 29 is rigid with the carrier 1 to receive the bolt 26. The platform 21 is also looked to the seat guides 30. The lever 25 projects above and below the platform 21. A cross bar 31 has two locking lugs 32 rigid therewith and these lugs are adapted to pass through the back of the seat and into the seat guides 30. The bar 31 is operatively connected to the lever 25 by a link bar 33 which is pivotally connected to the lever and to the cross-bar 31. The bar 31 is rigid with a stem or shank 34 which slides in the bracket bearing 35. A bracket bear ing 36 is provided for the bolt 26. The bolt 26 and the lugs 32 are operated simultaneously by the lever 25. The lever 25 is operated by a rod 37 which is pivotally connected to the lever 25 and to a yoke 38 which is pivotally connected to the back of the seat. An upward pull on the yoke 38 will release the seat from its mounting in the bracket 29 and the guides 30 so that the seat will instantly drop into the carrier 1. The guides 30 are rigid with the carrier 1 and the upright portion of the seat frame is provided with guideways which engage the guides 30 for causing the seat to descend directly into the carrier. A spring 80 will prevent accidental movement of the lever 25.

A positive pull is provided for causing the seat to descend into the carrier. A shaft 39 is journaled in bearings 40 near the bottom of the carrier 1. A flexible strap 41 is attached to the seat platform 21 and to a. spool 42 which is rigid with the shaft 39. A coil spring 43 is mounted on the shaft 39 and one end attached to the shaft 39 and the other end attached to the carrier 1. WVhen the seat is elevated, the strap 41 will be wound off the spool 42 against the tension of spring Consequently, when the seat is released from its mounting, the spring 43 will exert a positive pull thereon to force the seat down.

In the operation of the seat in passing down into the carrier 1, there might be some accident that would have a tendency to move the seat back out of the carrier. In order to prevent such backward movement of the seat a pivoted dog 44 is attached to the seat frame 23 and a spring 45 bears against the dog 44. Two such dogs will be provided if necessary, one for each guide 30. Racks 46 are formed on the adjacent faces of the guides 30 and the dogs 44 will catch in these racks 46 and prevent backward movement of the seat.

When the locomotive is running, there will be considerable air pressure against the lid 2. In order that this air pressure may not interfere with the closing of the lid, valves 47 are provided in the lid and means are provided for closing the valves automatically as the lid is being closed. The valves 47 are provided with stems 49 which are pivotally mounted on the lid and pivotally connected to an actuating bar 50 which is slidably mounted in brackets 51. The end of the bar 50 is beveled and a lug 52 is attached to the carrier 1. When the lid 2 falls, the bar 50 will strike the lug 52.

This will cause the bar 50 to slide in its bearings and thus close all the openings 48 in the lid and the bevel will permit the bar 50 then to pass on by the lug 52.

Provision is made for automatically looking the lid 2 down on the carrier 1. A catch (or catches 53) is attached to the lid 2 by 11 means of bolts 54 which are provided with handles so that a person inside of the carricr can remove them. The bolts 54 can also be removed by any one on the outside, the

bolts having recesses in outer ends to be en- 1 gaged by an ordinary screw driver or other device. The lock or locks 55 for the catches 53 re attached to the carrier 1 and are slidable in bearings 56 and in the carrier and held in retracted positions by spiral springs 57. The lock 55 will be moved inwardly by the beveled surface of the catch 53 as the catch passes in the slot in the lock 55.

The carrier 1 may be padded by air cush- 1.0115 58 which are attached to the inside of the carrier and connected with each other in series from bottom to top of the carrier. Compressed air tanks 59 are mounted in the lower part of the carrier and provided with valves 60 which will be opened automatically by the falling of the seat platform 21. The tanks 59 are so connected with the air cushioning devices 58 that the valves 60 will turn the air into the cushions.

The front part of the carrier 1 is weighted at the lower part by a weight 61 for the purpose of making the carrier float in an upright position in case the carrier is discharged into water. The weight 61 would counter-balance the weight of the person in the carrier.

A weight 62 is attached to the inside of the front part of the lid 2 to cause the lid to fall promptly when released. The lid is held open by the seat in the manner set forth in the patents above cited. 'The seat is provided with a hinged section 63 so that the engineer can sit by the window in the cab. The hinged section 63 will swing upward and over on the seat proper when the seat descends into the carrier.

Provision is made for extinguishing the fire'in the fire box of the engine. A vessel 64 is mounted on the locomotive frameat a point convenient to the cab for containing water and chemicals. A bottle 65 is suspended in the vessel 6% for containing sul-' furic acid. Means are provided for breaking the bottle 65 by the falling of the carrier 1. One end of a cord or cable 66 is attached to the carrier 1 or to some object to be moved by the carrier when the carrier is falling. The other end of the cord 66 is attached to a lever 67 which is fulcrumed on the side of the tank 64. A slidable rod 68 in the tank 64 with one end projecting out of the tank and beveled. A suitable bearing 69 is provided for the rod 68. The inner end of the'rod 68 stands near the bottle 65. WVhen the cord 66 is jerked by the falling of the carrier, the lever 67 will drive the rod 68 inwardly with sufficient force to break the bottle 65 and release the acid therein which will. create a gas that will extinguish the fire in the fire box. In order for the gas to reach the fire box 70, a pipe 71 is provided to convey the gas to the fire box. A valve 7 2 is provided for closing the pipe 71 and the valve is provided with a handle 73 to be engaged by the lever 67 for opening the valve when the lever is actuated to break the bottle 65. The advantage of the present devices for breaking the bottle 65 is that the actuating devices are on the exterior of the tank. WVhen the carrier is discharged from the cab, the fire in the fire box 7 0 will be extinguished.

There is a connection with the carrier 1 of means for closing the throttle of the engine and holding the same closed when the carrier is discharged from the cab. A looking lug 74: is attached to the side of the carrier and the throttle holder 75 has a hook 78 adapted to engage the lug 74. A springactuated dog 76 is pivotally attached to a bar 77 and the throttle holder 75 has a rack 78 formed thereon and the dog 76 will engage the rack 79 and thus hold the throttle holder 75 in any position to which the carrier 1 moves the throttle holder. The bar 77 may be attached to the side of the cab.

One of the tanks 59 may be provided with oxygen for supplying oxygen to the carrier when the lid is closed and this tank has the same kind of valve as the other tanks to be opened when the seat falls into the carrier.
