Application filed February 16, 1915. Serial 1T0. 8,518.

To all whom it may concern:

Be it known that I, WILLIAM A. U'r'rz, a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Life-Saving Attachments for Locomotive-Cabs, of which the following is a specification.

My invention relatesto safety devices for escaping from locomotive engine cabs, and more particularly to a detachable carrier to be discharged from the engineers cab in case of danger; and the object is to provide a carrier or protecting device into which the engineer can inclose himself instantly in time of danger and which device will be automatically detached from the cab and delivered to the ground or other place for the protection of the engineer.

The object is to provide a device which will inclose the engineerand protect him against falling on the ground or stones or other dangerous objects and which can be sealed air and water tight and provided with a valve which the engineer can operate. The same device is equally as available for the fireman as for the engineer.

The object is to protect the engineer and the fireman against fire and hot water or steam and to provide a ready means of escape from the engine cab.

One object is to provide a carrier or deliverer which cannot be crushed or will not be crushed in times of accident and danger. The carrier can be so arranged relative to thethrottle valve lever and the angle cock of the air-brake system and the sanding devices that all these devices will be actuated by the falling of the carrier out of the cab. A The. engine may also be equipped with reversing devices which can also be actuated by the discharge of the carrier.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the'claims.

Reference is had to the accompanying drawings which form a partof this application.

Fig. 20 is a side elevat ion ofa carrier, partly in section, illustrating how a cylinder may be rotatably mounted in'the carrier.

Similar characters of reference are used to indicate the same parts throughout the v eral' views.

The carrier herein'show'n includes a cylindrical' body 1, provided with a bottom 2 and a lid 3, the lid being hinged thereto by hinges l. The bottom may be riveted to the body. The body may be provided with upholstering which can be held in place by a lining 4.; The carrier is to be mounted in the cab in the mostconvenient position without interfering with the engineers position or duties. The upper edge of the carrier is preferably mounted flush with the floor 5 of the engineers cab which is braced by the bar 6. The carrier is mounted on hangers 7 and pins which are operated as hereinafter set forth. The carrier is held against lateral displacement by hooks 9 which are attached to the frame 10. The hangers 7 are provided with braces 11 and the frame piece 6 is provided with braces 12. The hooks 9 engage eyes 13 which are bolted to the carrier. An upholstered seat 14 is provided and mounted on a back 15 and platform 16. The seat is braced by the braces 17 and 18 and held in operative position by rods 20 which project into Lbeam 21. Clutches 22 are attached to the back of the seat and engage the I-beam 21, as shown in Fig. 3 to guide the seat down in the carrier and back to positions shown in Figs. 1 and 6. Means are provided for holding the seat in these positions. Rods 20 are mounted in brackets 23 which are attached to the platform 16 and rods 20 are slidably mounted in the brackets 23. Spiral springs 24 are mounted on the rods and attached thereto at their inner ends and rest against the brackets 23 for seats. A T-lever 25 is pivotally connected to the back 15 of the seat and provided with handles 26. A T-bar 27 is pivotally connected to the lever 25 and chains 28 are attached to the bar 27 and extended down under pulleys or idlers 29 and attached to the rods 20. lVhen the engineer wants to go down into the carrier, he pulls on the handles 26 and withdraws the rods 20 from the I-beams 21. The seat and the platform will instantly drop down in the carrier. Spring buffers 30 are attached to the bottom of the platform to prevent severe bumps on the bottom of the carrier. When the seat drops, several things take place. A. spring lock 32 is attached to the back of the seat and this look 32 will engage the top channel bar 31 inside of the carrier, the carrier being provided with channel bars for bracing purposes. Spring locks 33 will also engage the platform 16 and hold the same down. The lid 3 Will close as soon as the seat disappears in the carrier. The seat is held backat the top by a latch 34 which is attached to a frame piece and engages an eye or bracket 36 which is attached to the seat. When the seat drops, the eye 36 slips off the latch 34. Springs 37 and 38 are attached to the frame piece 35 and bear against the lid 3 and a hinged latch 39 is connected to the frame piece 35 and bears against the seat 15. The lid 3 bears against the latch 39 and thus the seat and the lid are rigid with each other until the seat drops. The latch 39 will swing upwardly and the springs 37 and 38 will throw the lid down as soon as the seat passes below the latch 39. When the lid comes down, it will strike the vertical rod 40 which effects a release of the carrier. A disk 41 is mounted on a shaft 42. A bar 43 is pivotally connected to the disk 41 and has slot 44 near the outer end. The vertical rod carries a wedge or spear 45 which enters the slot 44 and will thus force the rod 43 outwardly and at the rod 43 will turn the disk 41. The rods or pins 8 are pivotally connected to the pitman rods 46 which are pivotally connected to the disk 41. When the disk 41 is turned, the rods 8 will be drawn from the hangers 7 and thus release the carrier so that the carrier will drop out of the engineers cab. When the carrier starts down, pins 47 which are rigid with the carrier will engage the pivoted bars 48 and these bars will force the carrier to swing outwardly and thus throw the carrier far enough to fall outside of the railway track. In order to prevent accidental dropping of the rod 40 a lug 49 is provided on the rod 40 and a spring 50 is attached to the inside of the cylinder 1 and provided with a lug 51 to support the lug 49 which is rigid with the rod 40. WVhen the seat drops down in the carrier, it will strike the spring 50 and press the lug 51 from under the lug 49 and hold the same away until the seat is raised. Thus the lugs 49 and 51 will not interfere with the operation of the seat. When the seat is raised, the rod 40 is brought back to normal position. The lugs 51 and 49 will come to their normal positions automatically. When the rod 40 is raised, it will adjust the pins 8 to their normal or supporting positions. When the rod 40 is forced down, the spear 45 draws the pins 8 inwardly. Provision is made for locking the pins in the inward position. The bar 43 has a lug 52 rigid therewith. The rod 40 has a spear or wedge 53 rigid therewith turned in the opposite direction to the direction of the wedge 45. In the downward motion of the rod 40, the lug 52 will be drawn against the wedge 53 and thus lock the bar 43 sta tionary. When the rod 40 is drawn upwardly, the wedge or spear 53 will engage the lug 52 and thus force the pins 8 outwardly. Means are provided for locking the lid 15 down closed. Pivoted locks 54 are mounted in the lid by means of brackets 55. The lock is held in locking position by a spring 56 which is loosely connected to the lever end of the look by a ring 57. The spring 56 is reinforced by a spring 59. A bolt 58 extends through the lid from the outside and extends through the spiral spring 59 and through the spring 56 and is provided with a nut 60. A. person within the carrier can release the lid by turning the nut 60 and forcing the spring 56 toward the lid. The nut 60 is provided with a handle (31. The lid can also be released from the outside. A wrench can be applied to the bolt 58 on the outside to turn the bolt to draw the lever end of the lock 54. in toward the lid. This would release the lock. The carrier may be provided with any simple valve 62 for the use of a person within the carrier to let in air when needed. The lid 15 may be provided with aweight 63 for mak in a cup 66 which is attached to the false.

bottom 67 by means of flanges 68. j The swinging discharging arms 48 are prevented from swinging out of place by the pins 47, the hangers 7, and by guards 69.

A variation of the carrier releasing devices is shown in Fig. 7. Instead of the'bar 43, an arm 7 O is rigidly attached to the disk 41 and is loosely connected with a spring 71 which may be attached to'the interior of the carrier 1. When the seat 14 F 5 drops down into the carrier, the platform 16 will bear the spring 71 and the arm 70 down and thus turn the disk 41 for operating the pitman rods 46.

A variation in thelid throwing means is J go gshown in Fig. 8. A weight 72 may be used to throw the lid instead of the springs 87 and 38. I

Fig. 10 illustrates one way of making a double carrier. The seats and the operating mechanism can be duplicates of the mechanism described. The carrier has two compartments instead of one. These compart ments may have communication with each other by an opening through the partition 4073 which separates the compartments,the

opening being indicated in dotted outline.

A variation in the carrier releasing devices is shown in Fig. 11. Lugs 74 are provided on the carrier 1. These lugs rest on .the armsll. The arms 11 are braced by the bars 75 which are pivotally connected to the armsll at their lower ends and hung on a bar 76 which is slidably mounted in double brackets 7 7 which are attached to the frame 10. The bar 76 simply projects through the brackets 77 on one side and at the other side extends over the top of the brackets and is provided with a lug 78 which projectsback through the brackets 77. This is done in f orderthat a single movementof a single bar will release both arms simultaneously. The arms or bars 75 project between the brackets 77 and the bar 76 and the lug 78 project through these bars as well as through the brackets 77. Means are provided for moving the bar 76. These devices are shown in Figs. 11,13, and 18. A spear or wedge 79 ismounted on each side of thecarrier and supported on the bars 76 and on bars 80 e5 'which are attached to the cab frame. Small brackets 81 may be attached to the frame to prevent displacement of the wedges. The bars 76 have slots 82- through which the wedges 79 operate to move these bars when the lid 3 strikes the wedges. The bars 80 have slots 83 into which the wedges 79 pro ject so that the wedges will not yield in wrong direction. The bars 76 must move but the bars must not move. Shoving the wedges 79 down will move the bars 76 out 75 of the ends of thebars 7 5 and thus let these bars swing down so that the carrier will drop downwardly. The bars 75 will drop down and rest on thebrackets 84 and the guards'85 will prevent the bars 75 from falling forward in the cab. Fig. 19 illustrates how the lidmay be made to fit down on the upper edge of the carrier, making a waterand air tight joint.

A different releasing mechanism is shown 35 in Figs. 12, 14, 15, and 16 from the releasing devices shown in figures previously described. A bar 86 is mounted in brackets 87 which'are to be attached to the cab frame. The bar 86 isprovided with roller bearings 88 and a slidable bar 89 is mounted on the roller bearings 88, it being understood-that similar bars to

bars

86 and 89 are mounted on each side of the carrier. The carrier is supported on the bars 89 by means. of lugs 95, 90 and ball bearings 91 which are mounted in the lugs 90. The

bars

86 and 89 stand locked together by a key 92 which projects above the bar 89 and bends under and projects up through the

bars

86 and 89. The key 92 is held in place by a spring 93 which is attached to the bar 86. When the lid 3 falls it will knock the key 92 out-of the bar 89 and on further motion'of the lid, it will strike a wedge 94 which will move. the bar 89 until the cut-out 95 registers with the cutout 96 in the bar 86. The bearings 91. and the lugs 90 of the, carrier will drop through. these cut-outs andthus release the carrier so that the carrier will be discharged as above described. The lid 3 is provided with lugs 97 and 98 forstriking the key 92 and the wedge 94 respectively. 11f such releasing devices as here described are used, such releasing devices as are shown in previous figures would be dispensed with. Thebottom of the carrier couldbe constructed differently. The bottom:can be made concave, as shown in Fig. .12. The spaces 99 betweenthe channelirons 31may be inclosed to form annular air spaces within the carrierto aid' in making the carrier'float. These spaces may be inclosed by sheet metal 100.

The brakes of the train may be applied b the falling of the carrier. The carrier is provided with a lug 101 and the handle .102. of the angle cock of a trainline103 may be projected into the path of the lug 101. When the carrier drops downwardly the lug-101 will turn the vangle cock and thus set the brakes. At the same time, the main throttle may be closed. A lug is made rigid with the carrier. A hooked rod 106 is operatively connected with the throttle 107 and the hook thereon projects under the lug 105. The rod 106 is connected to a chain 108 which runs over an idler sprocket wheel 109 and this chain is connected to a bar 110 which is provided with a lug 111. The bar 110 is suspended from a bar 112 which is mounted rigidly in brackets 113 so that the bar 110 is slidable. When the carrier drops downwardly, the lug 105 will pull on the bar 106 and thus draw the bar 110 so that the lug 111 will actuate the throttle 107 to close the same. When the carrier drops about nine inches, it will swing forward at the top so that the lug 105 will be disengaged from the rod ,106. During this operation, a sanding of the track will also be effected. A chain 11A is connected to the bar or rod 106 and runs over anidle sprocket wheel 115 and is connected to a bar 116 which is connected to the handle 117 of the sanding device so that the sand will be discharged by the air on the tracks. 118 indicates a sanding device of ordinary construction.

Simultaneously with the above described operations, a reverse lever 119 may be actuated to reverse the engine. lug 120 is made rigid with the carrier. A lever 121 is pivotally mounted in the cab with one end projecting under the lug 120 and the other end positioned near the reverse lever 119. A bar 122 may serve as a guide for the lever 121. When the carrier drops downwardly, the lug 120 will actuate the lever 121 and this lever will actuate the reverse lever 119.

A variation in the carrier is shown in Fig. 20. A cylinder 123 is mounted in the carrier 1 and is made rotatable therein so that if the carrier turns over to any extent, the cylinder 1255 need not necessarily be turned. Ball bearings 12 1 are provided to prevent friction against the carrier 1. The asbestos lining 125, shown in Fig. 0 may be used in all the variations shown.
