Aand is pl ovided @with llaislot 27 Iextendin lit anglesto tlie plane lofthe idool? adapted to neoeiyegthepine' of the lever G Cil for sliding and pivotal movement. As will be evident, when the lever G is oscillated in a horizontal plane, the pin 23 will be swung` about the pivotal Aaxis ofthe ,lever on the brackets l", and throughit's connection with the bar C cause the same to slide relatively to the door. The end of ythe bar C remote from the head 25 is cut away on itsouter` 'in Figure 4, the latch member D is inthe form of a ilat plate cut away on the inner side adjacent the outer` end to provide a raised hook member 31 presenting a downwardly and rearwardly inclined outer end face 32. Rearwardly of the face 32, the raised portion provides a vertical shoulder 33 and a downwardly and rearwardly inclined face 34. At the opposite end, the inner side of theV plate is also cut away to receive the tongue 28. A ledge 26 is left along the lower edge of the plate adapted to abut the lower edge ofthe bar C tolimit the downward movement of the latch plate D, the upper corner of the pivoted end of vthe plate being rounded off as clearly shown in,` Figure 4 so'a-s to permit the same to swing upwardly. On' its outer side adjacent the hook end thereof, the latch plate Dis provided with a laterally projecting locking l lug 35 adapted to engage within an opening 36 formed in the handle 19, when thelatteris disposed in the full line position shown in Figuresl and 2. It will be evident that the lug 35, when engaged within the-opening 36 of the handle 19 serves to securely interlock the parts, preventing the latch D from being raised independently of the handle.

The stop bracket A is in the form of a flat plate applied to the door stop 11, the same having spaced lateral flanges 37 extending 'along` the front and rear faces of the door stop 11, and lixed to said stop by screws or any other suitable means. The bracket A is also secured by two bolts 38- 38 extending through the post and the upper and lower ends of the bracket, respectively. Adjacent the lower end, the bracket is provided with an outwardly project-ing horizontally disposed shelf 89 provided with an upstanding flangek40 at its outer edge and a longitudinally extending rib 41 disposed parallel to the la.ngeand spaced inwardly therefrom, and connected thereto by a transverse rib 141. The plate is also provided adjacent the top and bottom thereof with reinforcing ribsr42-42 connected by a ver tically disposed web 43. Adjacent the shelf 39, the vertical kplate portionof thebracket A is provided with a projection 44 presenting a vertically disposed shoulder 45 andan inclined face 46 adapted to coact respectively with the shoulder 33 and the inclined: face l 2of the lat-ch D. As clearly shown in ing adapted to receive the bearing member 48 whereby the plate is pivotally mounted to swing in a vertical plane. The plate is retained in position by a washer interposedl between the head of the upper securing bolt 38 and the projection 48 of the boss 47. The plate B is of such a length as to project behind the flange 40 of the shelf 39 when in itsdepen'ding position. Along its front edge, the plate B is formed with a vertically disposed flange 50 adapted to abut a laterallyprojecting lug 51 formed on the handle 19. The lug and the flange are ybrought into abutting relation when the handle 19 is'disposed in horizontal position resting on the rib 41, and the plate B is swung to its lowermost position. The lan'geand lug are provided with alined perforations adapted to receive a padlock or the usual seal cmployed with devices of this character.

Assuming that the'parts are in the posi-V tion Ishown in the full lines inthe drawing, when it is desired to open the door, the fol lowing sequence of operations takes place.

l'The lead seal or other locking means isA lirst removed, after which the plate B is swung to thefdotted line position shown in Figure 1. rlhe lever Gr is then Aswung in a horizontal plane o n its trunnions by means of the handle 19, thereby disengaging the lug 85 on the latch plate D from the opening in the handle and causing the pin through its slotted connection with the bar C to nieve the latter to the left as seen in Figilres l and 2. The sliding movement of the bar C will cause the door to be positively forced away from the door kstop since the end of the latch plate D- is brought into abutment with the vertical web 48 of the stop bracket A.' Then thedoor has been thus partly opened, the hook portion ofthe latch D is disengaged from the projection 44 of the bracket A and the door fully opened by merely pushing the same in the usual manner. The latch may then be swung upwardly to dispose the same inwardly of the edge of the door so as to offer no obstruction. Upon the operator releasing his grip from the handle 19, the latter will drop downwardly automatically under the influence of gravity. It will be noted Vthat the handle isthus disposed in a vertical position inwardly ot the edge 13 c'flhe door, so that the same 'will otter no obstruction. The lever may be swung through an are of 180 in performing the door opening operation to the position shown in dotted 'li-nes in Figure f2. `When it is desired to close the door, the latter 'is moved to a position as near the stop l2 as can be conveniently done by the operator without the use of tools. The handle G is then brought to the dotted line position shown in Figure 2, thereby projecting the bar C outwardly, the latch member D being vli'rstswung downaardly to a horizont al posi-tion. The hooked por-tion oil the latch I) is then engaged; with 'the projection 44 o'l the bracket A' by pushing the door toward the stop, 'the inclined tace 82 ot' the latch plate D engaging the inclined tace le ot the projection 4A swinging the latch upwardly on its pivot until the shoulder 33 thereof passes beyond the shoulder 4.5 of the' projection lille, whereupon the latch will drop to the position shown in dotted lines in Figure 'l with thel shoulders d5 and 3S in engagement. Thereupon the operator swings the handle G horizontally 'from the dotted line tothe lull line position shown in Figure 2, thus positively pulling the door to `:tully closed position. vWhen this condition 'has been reached, the handle 19 et Vthe operating'lever rests upon the rib Ll-'l ot the shelf 39 and the. lug 35 ot the latch plate I) is engaged within the recess 36 to lock the latch plate to the handle. During the operation oi closing the door, the Vpivoted connection between the arnrC and latch plate D will be retired withinthe guide E, preventing relative movement of the parts, the guide E acting as an additional means tor preventing lifting ofthe latch plate. The locking' plate B is then `dropped into position in front ot the handle 19 with lthe lower edge lot the plate disposed in back of the flange el() and the flange 50 in abutment with the lug 5l. The padlock or seal may be then passed through the alined openings in the lflange and lug. Although I 'have herein shown 'and described the latch plate l) as held against upward movement both by engagement of the lug 35 with 'the recess 36 oi2 the handle and by the `pivoted connection between the arm C and the latchplate I) being retired within the guide E, it. will beevident that either ,of these means' alone will vserve the purpose and that the other may be entirely omitted.

Although I 'have hereinshow'n and described the bracketrA and the latch plateV B as secured to the doorpost and the lever mechanism withassociated parts'as secured to the door, it will beevidentjthat the posi-- tion of the parts may be rever-sed without depart-ing from the spirit ot the invention.
