T 0 aZZ whom it may concern Be it known that I, CARL A. GARLsoN, a sub ect of Sweden, and a residentof the cityand county'of San Francisco and State of California, have invented certain new and useful improvements in Door-Controlling Mechanism, of which the following is a-- specification.
The invention relates to unlatching and opening and; closing doors or similar structures from from the door or structure.
The object of the invention is to provide a mechanism which operates to unlatch the door before it operates to swing the door open.
A further object of the invention is to provide simple and novel means of a cheap and compact construction for performing this function.
The invention may be better understood by reference to the accompanying drawings illustrating the preferred form of the mechanism of my invention, in which Figure 1 is a horizontal section taken through the door and wall framing above the mechanism. Fig. 2 is an elevation partly in section of a fragment of the door and surrounding structure, illustrating the latch operating mechanism. Fig. 3 is a plan view of the mechanism attached to a door on a larger scale. Fig. 1 is a view of the cross to which the operating wires and rod are attached.
The mechanism of my invention is arranged with relation to the door 2 so that when it is operated from the remote control, it operates first to disengage the bolt 3 of the look from the door frame 4 and then to swing the door open. Attached to the door 2 preferably at its lower portion is a bracket 5; which is engaged by the end of a lever 6, pivotally attached to the bracket 7 secured to the door framing or other permanent part of the building. The center of rotation 8 of the lever 6 is spaced apart from the pivot of the door hinge, so that the lever is movable relative to the door. The lever 6 is provided with a slot at the pivoted end in which is arranged the lever 9, pivotally attached to the lever 6, and capable of limited movement with respect to the lever 6. This lever 9 is operated through the link 12 connected thereto and to the bell crank 13, which is pivoted to a permanent part of the building. The bell crank is connected by the link 14 with the cross 15, to the opposite legs of which are connected mechanism for posit-ions remote;
- .9 engages theclosed end of the slot.
lever 9 is provided with a shoulder 21 which wires l6 -l7rextending to a lever at the controlstation. The lever at the control station; is provided with a handle, as is cusztomary, and the door is operated by the movement of the handle.
The lever 9 is arranged adjacent the closed end of the slot in lever 6 and the side of the lever adjacent theclosed end is provided with a cut-away face 18, so that it has a motion independent of the lever 6 for ashort distance before the side of the lever The engages a shoulder 22 on the lever 23 fulcrumed on the pivot 8. Bearing against the free end 24 of lever 23 is a lever 25 pivoted at its upper end to a fixed part of the building and having its lower end eX- tending below the fioor 26. Attached to the lower end is a rod or wire 27 extending across the width of the door and connected to a bell crank 28 which is in turn connected to the lever 29 by the rod or wire 31. The lever 29 is arranged in the door framing adjacent the bolt of the lock and operates to press the bolt out of its keeper, thereby allowing the door to be opened. A. spring 32 attached to the lever operates to hold it in normal inoperative position and to return it to such position when the tension in wire 31 is released.
The operation of the device is as follows: When the door is closed and locked, the parts are in the positions indicated in the drawings. As pressure is applied on the operating handle to open the door the lever 9 is first moved independent of the door. This movement causes a movement of the lever 23 which operates the latch releasing mechanism. When the latch has been released, the face 18 of the lever 9 engages the closed end of the slot in lever 6 and the continued pull on the lever swings the door open. \Vhen the door is to be closed, the latch releasing mechanism has already returned to its normal position under the action of the spring 32, and when the door reaches the closed position it is latched.
I claim:
1. The combination with a hinged door provided with a latch, of a lever operatlvely connected to said door fulcrumed adjacent the door hinge and provided with a closed end slot, a second lever arranged in said slot and fulcrumed on said first lever and adapted to engage the closed end of Said slot, said second lever having a limited movement independent of said first lever, means for moving said second lever to bring it into contact with the closed end of the slot and means operative by the independent movement of the second lever for releasing the latch.
2. The combination with a hinged door provided with a latch, of a lever having a closed end slot operatively connected thereto, a second lever arranged in said slot'and fulcrumed to said first lever, said second lever having a limited movement independent of the firstlever, a third lever fulcrumed at the pivot of said first lever, shoulders on said second and third levers in contact with each other, and means engaging said third lever operative to release said latch.
3. The combination with a hinged door provided with a latch, of a lever having a Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
closed end slot operativelv connected to said door, a second lever pivoted adjacent the closed end of said slot and arranged to contact therewith at the end of its throw in either direction, a shoulder on the side of saidlever remote from said closed end, a
third lever fulcrumed on the pivot of the first lever, a shoulder on said lever engaging the shoulder on the second lever, a lever 30 set my hand at San Francisco, California,
this 11th day of June 1912.
