DOOR OPERATING LEVER.
APPLICATION HLED AUG-16. 1911.
Patented Nov. 12, 1918,
vgxgx HERBERT W. CRANE, OF CHICAGO, ILLINOIS.
DOOR-OPERATING LEVER.
Specification of Letters Patent. Patented Nov. 12 1918.
Application filed August 16, 1917. Serial No. 186,519.
To all whom it may concern:
Be it known that I, Hnnenn'r W. CRANE, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Door Operating Levers, of which the following is a specification.
My invention relates to door opening devices and particularly to a novel bracket for use in connection therewith.
My improvement is intended primarily for application to swinging doors. One of the principal objects is to provide means for securing the requisite leverage for bringing the door to fully closed position. This has been accomplished heretofore by the provision of a projecting bracket secured to the door. The objection to this has been that the door could not be fully opened in 'a 90 space because of the projecting bracket. In the construction herein proposed the requisite leverage is secured for bringing the door to a closed position and the bracket is articulated and assumes a collapsed position. In order to accomplish the desired result the bracket is formed of two members or struts, the inner ends of which are fulcrumed on the door and frame respectively, their outer ends being pivotally joined. The rack bar is connected at a point intermediate the ends of the strut which is connected to the door. When the door has been swung"90, the bracket will assume a different position in which the member connected to the door lies substantially parallel to the door.
A further object is to provide means for connecting an actuating bar to the bracket in such manner that there will be a very slight angular movement of the bar in its travel. This is essential where the bar is in rhe form'of a rack actuated by a motor pinion.
The invention will be more readily understood by referenc to the accompanying drawing, wherein,
Figure l is a plan View partly in section showing the device in operative position on a door, and,
Fig. 2 is a front elevation thereof.
In the drawings the door frame is indicated at 10, and two swinging doors at 11, 12. A motor 13, is mounted at the meeting edges of the doors and at a point thereabove. Two rackbars 14, 15, are operathe two links being pivotally joined at 21.
. The position of the parts when the 'door is in open position is shown in dotted'lines in Fig. 1. In that position it will beseen that the rack bar is in substantially the same straight lines as when the door is in closed position. The path of travel of the end of the rack bar from the open to the closed position of the door. is indicated by the curved dotted line 22. It will be seen that there is comparatively little angular movement of the rack bar even at that distance from the actuating pinion and therefore that there will be no interference with the operation of the motor. By reason of the arrangement shown it will be seen that the door may be opened against a .wall arranged at 90 to the door when in closed position. This is important in garages which are frequently so designedthat the door is set deeply in the building and swings against a 90 wall.
While the construction is shown in connection with double swinging doors it 'may be used with equal facility for single doors and may be arranged in other manners than that shown. Modifications in the arrangement are therefore considered .tobe covered herein.
I claim:
1. In door operating means, the combination with the door and casing, of an articulated bracket mounted on the side toward which the door opens, one bracket member being fulcrumed to the casing at a point inside of the hinge for the door, an other bracket member being fulcrumed on the door at a point substantially midway of its width, and an actuating bar connected to the last named member intermediate of its ends, the two bracket members being of substantially equal length and being pivotally joined at their outer extremities, substantially as described.
2. In means for actuating swinging doors, the combination with the door and casing, of a bracket mounted on the side toward which the door opens and formed of two links of substantially equal length pivotally joined at one end, one of said links being fulcrumed to the casing ata point a substantial distance inward from the door hinge, the other link being fulorunied on the door at a point a further distance in-. ward of the hinge whereby when the door is in closed position the links project awa; from the door, and an operating member connected to the last named link at a point intermediate of its ends, the arrangement being such that as the door is opened at an angle of 90 to its original position, the last named link will lie substantially parallel to the door, substantially as described.
3. In means for operating doors, the coinbinetion with a swinging door adapted to he opened 90 against an adjacent wall, of
a bracket mounted on the side toward which the door opens and composed of two links of substantially equal length pivoted together, the free end of one link being t'ulclaimed to a support at a point a distance from the adjacent wall substantially equal to the length of the link, the other link being fulcruined on the door at a point substantially midway of the width thereof, and an operating har connected to the last named link at a point intermediate the ends thereof, substantially as described.
