OCONNOB, OF CHICAGO, ILLINOIS, ASSTGNOR T0 UNION RAILWAY EQUIP- MENT COMPANY, 0F CHICAGG, ILLINOIS, A CORPGRATIGN OF ELLINOIS V OPERATING non noons Application filed January 23, 1928. Serial No. 248,708;

This invention is primarily designed for use in connection with doors for refrigerator cars in which it is desired to make provision for the forcible opening and closing of the doors. In doors of this character, it is or- 'dinarily necessary to provide some means for imparting a final thrust in the closing of the door and an initial pull in opening the door, since it is necessary in doors of this character to provide for a tight and close sealing of the door against the passage or" air, so that it is difficult to manipulate the door by hand in the absence of special means for forcing the door into or away from its final closed position. v

The present invention relates to the use of a bail shaped operating bar or handle which is so arranged as to afford a high leverage ratio in order to easily force the door shut or pry it open, the arrangement being one which also enables the operating bar to serve as a handle in drawing back the door when initially opened.

Further objects and details will appear from a description of the invention in conjunction with the accompanying drawings wherein Figure 1 is a front outside elevation of a car door in closed position;

Fig. 2 is an enlarged detail looking down wardly from the position indicated by the line 22 of Fig. 1; r

Fig. 3 is a view of the upper part of the door and casing taken at right angles tov hook 25 terminating ina rearwardly project.-

Fig. 2;

Fig. 4; is a section taken on the plane of line l l of Fig. 3, looking in the direction of the arrows but showing the parts in the relation assumed as the door begins to open; Fig. 5 is a detail showing the guide stop for supporting the operating bar; and

Fig. 6 is a view similar to Fig. 2, showing the door opened to'the extent provided for in the operation of the'present invention.

The present invention is applied to a double door comprising sections 10 and 11 mounted on hinges 12 secured to the side walls 13 of a door opening, the upper edge of which is atforded by a beam or lintellt. The free inner edges of the door sections are preferably correspondingly beveled in the usual manner, so that when swung together they will afiord a tight or close fit to prevent the passage of air. The door section 10 is provided nearits tree vertical edge with a pair of plates 15 which are bolted or otherwise secured at the upper and lower ed es of the door section respectively, and each plate is formed to afford an outstanding face wall 16 from which projects stud 17, said stud projecting vertically beyond the upper and lower edges of the door respectively.

Each otthe studs is positioned to co-act with the inner end of a horizontally disposed arm 18 which in conjunction with the con necting bar 19 constitutes a bail shaped operating bar of suitable dimensions to em brace the door section when adjusted to the closed position shown in Fig. 1. The operating bar as a whole may be formed of a i on a head 21 of special configuration to co- 'act with the stud 17 in opening and closing the door sections.

The head 21 on its outer side is formed solid to afford a fiat wall 22 from which inwardly extends a vertically disposed cam wall 23 having the special configuration best shown in Fig. l. The cam wall at its inner end 24 is curvedacross the head 21 and at its outer end is reversely turned to aliord' a ing lip 26 which is carried backwardly beyond the center of curvature of the hooked portion 25, the lip 26 being extended suiticiently to bear against the inner side of the stud 17 as the bail shaped operating bar is swung on a pivotal center which will now be described.

The solid outer wall 22 of the head is provided near its outer end with a vertically extending trunnion 27 which is journaled within a journalhead 28 outstanding from a journal plate 29 bolted or otherwise secured to the door casing at a point in close proximity to the free vertical edge of the door section 10. The formation of the head is one which provides a solid wall on the outer face only, the opposite side,toward the associated stud 17, being open or cut away. In Fig. 4, the position of the trunnion 27 is indicatedin dotted lines from which it will appear that the hook 25 in swinging will engage with the stud 17. As shown, the dowel stud 20 is held in socketed relation within the end of the. arm 18 by the provi sion of cross pins 30, or the like.

In order to better guide the operating bar when swinging, and to prevent sagging thereof, a pair of uide plates 31 and 32 are provided, the ormer of which is secured to the door casing below the position assumed by the lower arm of the operating bar when closed, and the latter of which is secured to the door itself near its upper edge. Each plate 31 and 32 is formed to afford a curved upperguide face 33 (see Fig. 5) upon which the associated arm 18 will ride as the bar is being swung to closing position. 7

In order to hold the operating bar locked,

the bar section 19 is provided with a slot-.

ted plate 34', the slot of which registers with the staple 35 outstanding from a plate 36 on the adjacent side wall of the door opening,

the hook 37 being provided for hooking throughthe staple after the plate has been registered therewith. The door section 11, which is first closed in the closing of the door, is adapted to be held closed by the provision of a bolt 38 which when thrown passes through a socket 39.

In use, with the doors in the closed relation as illustrated, the bail shaped operating bar when swung on its trunnions 27 will cause the lips 26 on the upper and lower heads 21 to swing outwardly into contacting relation with the upper and lower studs17 which are secured to the door. A continued swinging movement of the operating bar will thus impart an outwardly directed thrust to the free vertical edge of the door which will pry it open after which the lips will swing clear of the studs 17, permitting the handle to be swung over to the left in Fig. 1, as indicated in dotted lines, at which point it may be secured upon the staple 36 there located.

As shown, the journal mountings for the 7 operating bar are centrally located above and below the door opening, although the door section 10 by reason of its beveled overlapping vertical edge extends, when closed, to a point slightly to the left of the center line. The arrangement is one which enables a very high leverage to be secured, and in view of the fact that only a slight amount of swinging movement need be imparted to the edge of the door to pry it open from its closed relation, the length of the lip 26 need only be sufficient to effect this initial opening movement after which the lips will swing free from the studs and the operating bar may be thrown over to the 7 doors fully swung over to the right and with the door section 10 slightly open, the lips 26 will clear the studs 17, so that the final closing movement is effected by a contact of the solid walls 23 of the heads 21 with the respective studs which are forced inwardly as the operating bar is swung to its ultimate position at the right. The arrangement is one which involves extreme simplicity in construction, and, at the same time, a very effective thrust may be imparted to the edge of the door both during the opening and closing movements. Furthermore, by locking the operating bar in its closed relation, the doors will be effectively locked without the need of additional securing means on the doors themselves.

Although the invention has been described with partlcularity as to details, it is not the intentionto limit the invention to the construction shown, since modifications thereof may be introduced without departingfrom the spirit of the invention. V i
