MEANS FOR OPERATING SLIDING DOORS.
Specification of Letters Patent.
Patented Oct. 1'7, 1916.
Application filed May 20, 1914. Serial No. 839,686.
To all whom it may concern Be it known that I, AUGUST KRAUsE, a citizen of the United States, residing at Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Means for Operating Sliding Doors, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.
This invention has reference to improvements in means for operating sliding doors particularly double sliding doors used at the landings of elevator shafts.
One object of the invention is to so construct a sliding door operating mechanism that by a straight pull in the direction in which the door moves the operator may unlatch or release the mechanism and move two sliding doors to the open position and that by the energy stored by the opening movement of such mechanism both of said doors may be returned to closed position and the mechanism be again latched.
Other objects of the invention will appear from the following description.
The invention consists in the means for operating the sliding doors.
The invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claims.
Figure 1, represents a view in elevation of a pair of sliding doors or gates provided with the improved operating mechanism. Fig. 2, represents an enlarged detail sectional view of portions of the same taken on a line between the numerals 22 Fig. 1. Fig. 3, represents an enlarged detail view of the latch mechanism.
Similar characters of reference designate corresponding parts throughout.
As shown in the drawings, in its preferred form 5 represents a door frame having the tracks 6 and 7, and 8 and 9 represent independent sliding door sections slidingly engaged with the track 6 and having respectively the sheaves 10, 10 and 11, 11 operating on track 7.
Door section 8 has the vertically extending guide 12 through which extends the rock shaft or rod 13 sustained at its lower end by the handle member 14 which is mounted on said door section 8 at a convenient hei ht and, at this lower end, shaft or rod 13 has and the bevel end 21. This latch arm 18 is pivotally mounted on the fitting plate 22 which is fixed to the upper portion of door section 8 and said latch arm is pressed in the latching direction by the spring 23.
At theupper portion of the frame 5 is mountedthe casing 24 having the shaft 25 adapted to be rocked in one direction, the door closing direction, by the spring 26 and on said shaft 25 is mounted the arm 27 having near one end the pivoted hearing or slide 28 which is slidably mounted on the guide 12 and that portion of arm 27 which extends beyond slide 28 has the pin 29 which is adapted, in the upward movement of this end of arm 27, to ride over the bevel end 21 of latch 18 and engage with one of its notches 20 or 19 as the case may be. Pivotally connected with closer arm 27 is the link or rod 30 which is also pivotally connected with the rear portion of door section 9.
With the parts in position as shown in Fig. 1 the handle member 15 is grasped by the operator and drawn in the direction to efiect the opening movement of door sections 8 and 9. The movement of this handle member 15 effects the rocking of shaft 13 and the swinging of its finger 16 to effect the swinging of latch 18 through link 17 thus releasing this latch from pin 29 whereby said pin and the corresponding end of arm 27 with its slide 28 is free to move downward, slide 28 of course sliding downward on guide 12 while the backward swinging motion of arm 27 is transmitted through link 30 to door section 9 so that door sections 8 and 9 slide backward simultaneously until arm 27 and link 30 are approximately in the position shown in dotted lines in Fig. 1 and, in such movement, the rotative movement of shaft 25-has tightened spring 24:. In this latter position spring 24 is under suflicient tension to efiect the closing movement of arm 27 and such movement is transmitted to doorsection 8 through slide 28 and guide 12 and to door section 9 through link 30. As said door sections approach the closed positions, shown in Fig. 1, pin 29 of arm 27 rides over the bevel end of latch 18 and engages one or the other of the notches 20 or 19 of said latch depending upon the degree of the closing movement of the door sections, in either case however effecting the locking of both door sections against opening movement.
Having thus described my invention I claim as new and desire to secure by Letters Patent 1. Means for operating slidable doors comprising a door slidably mounted and having a vertical guide, a latch rod journaled in said guide and having an operating handle, a latch connected with said rod, a door closing arm having a bearing slidable on said guide and also having means adapted to be engaged by said latch, and a spring motor for operating saidclosing arm in the closing direction.
2. The combination With a pair of slidable doors, of a spring motor mounted above their path of movement and having a door 20 closing arm, a link pivotally connected With sa1d arm and Wlth one of sa1d doors, a bearing pivotally mounted on said arm, a vertical guide, on the other of said doors, on
Which guide said bearing is slidable, a pin at 5 handle adapted to limit the movement of 30 said latch operating handle. 1
