Application iiiea' September a 1922, Serial 1%; State. iteiieiiea my 5?, 1925'.

To all whoin it may cojn'c'e'rn: Be it known that I, Leivniiiion V. iioiiii, h citizen of the United states,- fesiding' at Lima, in the county of Allen and State 0i Ohio, have invented, certain haw and useful Improvements in Sealing I ocks and Dooi Starters, of Which the iei-lowing is a specification. p I

The principal Object of the present invention is to provide a door operating mechanism comprising means for controlling the nioveiiiehts of the doer operating lever. A further object is to provide means for preventing the parts of the door mechanism from swinging outwardly av'v'ay froin the car. The limitations imposed upon the clearance at each side of a railway cai inake it necessary to prevent appliances attached to the car Walls from swinging outwardly beyond the allowable liinits of this clearance when the car is passing around a curve or when a side sway is set up due to a rough track, and this object. is attained in the present invention by providing ineans for maintaining the parts of the door operating and locking mechanism in position adjacent to the plane of the car wall.

The various objects and advantages of the invention will appear more clearly from the following specification taken with the accoinpan'ying drawings in which several emloodiinents are illustrated. In the drawings,

The invention is "shown in ohiiectieii with a car deer 20 adapted to close the'u'sual door opening in the side Wall 21 of a railway cai. Ohe horizontal edge of the deer is inoiinted to travel on track and the other horizontal edge travelsiii a horizontal guidetvay in the usual ma nnei so that the door inoves horizontally'alon-g the car 'Wall when travelling to or from the closed position illustrated in I Fig. 1. The Iading' edge of the door is adapted to seat againsta deer j ihh 22 which is secured to the outer E'sid of the ushildobr post 23 extending vertically at the side of the door opening. The face 22 of the door j mb is offset from the inner parallel face of the door post 'so that the edge of thedoor ie adapted to overlap the door pastas shown at'24. The inside sheathing 25 and the outside sheathing '26 of the car Wall are sec'nred to the door poet 23 in the nsnal manner, and a filler plate 27 is inserted between the out- Fig. 9 is "i perspective View of the leh'iiiiig 1g. 13 is h sectional view on the line side sheatliing ai d the door iainb as shown way to receive the leading edge of the door.

The door 20 is operated by a lever. 30 having perture 31 "which is pivotally ehgigedby h pin or bolt 32 passing throngh the outer flange 33 and the inner plate 33 of a bracket 33. This bracket seats upon a plate 34 secured to the outer side of the car door and is secured to the door by rivets 35 passing through the bracket and the door and also preferably through a plate 36 10- cated on the inner side of the car door. The aperture 31 in the lever 30 is somewhat loosely engaged by the bolt 32 and has some freedom of movement betweenthe

flanges

33 and 33 of the bracket so that it can be swung outwardly to some extent away from the car door during the operation of the locking mechanism as hereinafter described. The body portion of the lever 30 is provided with two

vertical apertures

37 and 38 of rectangular cross-section which are formed through the enlarged

parts

38 and 39 thereof respectively. Reinforcing ribs 40 extend longitudinally of the lever. A vertical flange 41 extends inwardly from the lever adjacent the aperture 37, and two other spaced flanges 42 extend inwardly from the lever adjacent the aperture 38 for purposes hereinafter described.

The door operating lever 30 is adapted to engage a locking bracket or casing 45 which seats upon the outer side of the plate 28 secured to the door jamb. This bracket comprises a base plate 46 which seats upon the plate 28, being provided with a downwardly extending flange 46 and a laterally extending flange 46 which have

apertures

47 and 48 therethrough respectively, adapted to be engaged by

bolts

49 and 50 respectively which extend inwardly through the door jamb and through the door post. This bracket is further provided with two outwardly extending

bosses

51 and 52 which have vertical aligning apertures 53 and 54 extending therethrough respectively, these apertures being of substantially the same size as the

apertures

37 and 38 in the lever 30. The

bosses

51 and 52 are spaced apart vertically to leave an intervening slot or notch 55 adapted to receive the lever 30, and

the aligning apertures 53 and 54 are adapted to receive a vertically slidable locking member or bolt 56 which may engage either one of the

apertures

37 or 38 formed through the lever. The locking member 56 has an outwardly turned flange 57 at the upper end thereof which overlaps the upper boss 51 and limits the downward movement of the locking member. The member 56 is further provided with a longitudinal slot 58, adapted to be engaged by a bolt 59 which extends through the aperture 60 in the walls of the boss 51 and thence horizontally through the door jamb and the door post, as shown par ticularly in Figs. 2 and 5.

The base plate 46 of the bracket 45 is further provided with a flange 62 projecting outward y from the inner edge thereof between the bosses 51 and When the aperture 37 in the lever 30 is engaged by the locking member 56, the flange 41 of the lever engages the inner surface 62 of the flange 62, thus holding the door against movement and relieving the strain upon the locking member 56. When the aperture 38 in the locking lever 30 is engaged by the locking member 56, thus holding the door in a partially open position, the flanges 42 of the lever engage the opposite sides of the flange 62 and thus provide a rigid connection between the casing 45 and the locking lever when the door is in that position.

The locking member 56 may be secured in its lower-most position by means of the usual car seal 64 which engages the slots 65 in the sides of the boss 52 and a similar slot 66 which passes through the lower part of the member 56. The lower part of the locking member 56 is also provided with an aperture 67, which intersects the slot 66, and an opening 68 is provided in the outer wall of the boss to register with the opening 67 when the member 56 is in its lower position so that access can be had to parts of the car seal within the boss 47, for convenience in removing the parts of a broken seal, for example. A more secure locking of the member 56 may be effected by means of a padlock 70 which is adapted to engage registering apertures in the

ears

71 and 72 which are formed on the casing 45 and the bolt 56 respectively, as shown particularly in Fig. 1.

The positive opening and closing moveuents of the door, when it is near the door post, are effected through the upward extending arm 75 of the lever 30. This arm extends between the flanges 76 of a rod or latch member 77 and is pivotally connected thereto by means of a bolt or rivet 78. The

79, which unites the flanges 76, is V- shaped in cross-section, as shown in Fig. 1, so that it engages the inclined arm 7 5 and prevents the rod 77 from swinging downwardly out of a position substantially parallel to the lever 30. The rod 77 is provided with an enlarged head 80 having a notch or recess 81 cut in the under side thereof to enthe boss 82 formed on the upper part of the casing 45 around the aperture which is engaged by the bolt 59. When the notch in the rod 77 engages this boss 82, an operating connection is formed between the rigid door boss and the pivot 32 of the lever 30,

so that when this lever is swung outwardly from the notch 55 of the casing 45, after upward movement ofv the locking member 56 to the extent permitted by the slot 58, the pivotal movement of the lever 30 then operates to effect a positive movement of the door toward or away from the door 'jainb 22.

When the door is in a partially open position, the rod 77 is supported in a position substantially parallel to the lever 30 by the LTI V-shaped web 7 9 and as the door reaches a position near the door post, the rod 77 can be swung upwardly from the lever to cause the notch 81 thereof to engage the boss v82, whereupon an upward swinging of the lever will effect a positive movement of the door toward the door jamb. In a similar way the downward swinging of the lever with the notch 81 engaging the boss 82 will effect a positive movement of the door away from the door jamb. I

lVhen the operating lever is not secured to the casing by the locking bolt 56, the loose pivotal connection of this lever with the bracket 33 might permit it to swing outwardly from the car door beyond the limits of the allowable clearance, if

means be not provided for overcoming this possibility, and the outer flange 33 of the bracket 30 is therefore provided with a downwardly extending part 85 having, an inturned lug 86 at the lower end thereof which is adapted to co-act with the outer face 87 of the lever 30 when the lever is suspended in a vertical position, as shown by dotted lines in Fig. 1. The lug 86 is provided with a rounded surface 86 which engages the edge of the lever 30 as it swings to its suspended vertical position, thus forcing the lever inwardly so that it is held in a position parallel to the car door. When the lever is in this position, injury to the car door by the flanges 41 and 42 of the lever 30 is prevented-by a plate 88 which is secured to the car door by screws 89 and engaged by the inner extremity of the flange 42 A modified form of the construction for preventing the outward swinging of the lever is illustrated in Figs. 10 and 11 where a lever 90, similar to the lever 30 in construction, is loosely pivoted on a bolt 91 extending between the flanges 92- ancl 92 of a bracket 92. In this construction the flange 9 2 has a downwardly extending part 93 provided with an inturned lug 94 having the inner surface thereof inclined as shown at 94 so that this inclined surface is adapted to engage the surface 95 of the lever 90 and positively force the lever inwardly toward the car door as it swings to its vertical position, thus maintaining the flange 96 of the lever in contact with the plate 97 secured to the car door.

A third form of the lever controlling device is illustrated in Figs. 12 and 13 where a lever 98, similar to the lever 30, is mounted between the

flanges

99 and 99 of a bracket 99, being'pivoted on a bolt 100'which extends through these flanges and through the car door 101. In this construction the downwardly extending projection on the co-act with a lug 103 formed on the adjacent said door when it is face of the lever 98. These lugs are provided with co-acting inclined surfaces'104 and 105 which engage each other to force the lever toward the car door with the inwardly projecting flange 106 of the lever co-acting with the wear plate 107 secured to the car door. These lugs having the coacting inclined surfaces are out of engagement with each other when the lever 98 is in the position to be swung outwardly to be engaged with or disengaged from the locking bracket secured to the door jamb, but as the lever approaches its downward vertical position, the lugs engage each other and gradually force the lever inwardly to hold it against outward swinging away from the car door.-

A fourth modification of the invention is illustrated in Figs. 14'and 15 where a lever 110, similar to the lever 30, is pivoted on abolt 111 extending through the

flanges

112 and 112 of a bracket 112 secured to the car door 113. In this construction both the inner and outer flanges of the bracket are provided with downwardly extending parts having

inturned lugs

114 and 115 formed on the lower ends thereof. These lugs are provided with inclined surfaces116 and 117 adapted to receive the lever 110 when it swings to its suspended vertical position. These inclined surfaces engaging opposite sides of the lever force the lever into a position parallel and in proximity to the car door with the projecting flange 118 of the lever held out of engagement with.

the car door so that the use of a wear plate is unnecessary. 7
