Patented June 17, 1930 UNIT rf'rss PATENT OFFICE 7 WILLIAM J). nnnn s, on srnnnIiiG, I .t I\IoIs, nss'ienon rossnnrz nnhemorname 00., OF STERLING, ILLINOIS, A CORPORATION on ILLI Nois nooniionr Application 'fi-led May in, 192's. shin-n0. ea-e545.

This invention relates to bolts or latches for doors or windows, especially for doors or windows that are hinged. to swing open and shut, and more particularly to bolts or latches for this purpose that look the top of the door in closed position, and which have a chain or cord which can be pulled to disengagethe bolt from it's socket or engaging means when it is desired to open the door or window.

Generally stated, the object of the inventi'on is to provide a novel and improved construction whereby a bolt or latch of this character can be operated from" outside the door or window, as well as from inside, means being provided toeXert a pull on the said chain or cord from outside the door, as well as from inside thereof.

It is also an object t provide certain details and features of construction and combinations tending toincrease the efiiciency and the desirability of a pull cord or chain bolt orlat'ch ofthis particular character.

To the foregoing and other useful ends, the invention consists in the matters hereinafter set forth and claimed, and shown in themcompanying drawings,in which,

Fig. 1 is a vertical section of a portion of a door and the overhead portion of the door frame, showing a bolt or latch therefor embodying the principlesof the invention, portions of said bolt or latch mechanism being.

shown in vertical section, and certain parts of the door and the pull chain being shown I broken away for convenience of illustration;

F 2 is an enlarged view lookin down on the said bolt or latch mechanlsm, s owing 'the'adjaeent portion of the door in horizontal section;

4 Fig. 3 is an enlarged horizontal section on 4 preferably inside thereof; Inside this casing there a hollow bolt member 3 that is adapted to move up anddown, a pivoted catch 1 being pivoted on this bolt member at 5, as shown. The bolt member may be formed of sheet metal, as shown, and the ears 6, between which the catch l is pivoted, extend outward and are movableup and down in the guide slot 7 formed in the outer side of the casing. .A cross piece 8 is suitably attached to the side walls of the casing and forms a guide for the other side of the vertically reciprocating bolt member. A coiled spring 9 has its upper end in engagement with the under side of thecatch 4,'and the lower end of this spring rests on the support 10, which 4:, as shown. An angle piece 13 is secured to the overhead portion 14 of the doorway,by screws 15 or any other suitable means, this angle piece having a lower horizontal flange 16 and'being' provided with an opening 17 in the elbow between the vertical and horizontal portions of this angle piece, which latter serves as a strike piece for the bolt member and the catch. Q

When the door is fully closed, the overhanging upper end 18 of the bolt .meniber rests on the flange 16, and the hook portion 19 of thecatch is in engagement with the openingl'i, whereby the door is supported by the bolt member and the angle piece, and is of the catch with the opening 17 of the strike .Iece. p In order that the bolt and catch mechanism thusprovided may be operated from outside the dooryas well as from. inside thereof, the inner side' of the door is provided witha handle or grip 20, and the outer side of the doorisprovided with a bracket 21 having upper'and

lower guides

22 and 23. for the

vertical portions

24 and 25 of the handle 26, whereby this handle is moved up and down.

latched in closedposition by the engagement doors.

An arm 27 is mounted on the upper vertical portion 24 of the outside handle, and extends through a slot 28 in the door. A pull chain or cord, or other connection, 29, connects the lower end of the rod 11 with the arm 27 in the manner shown. A thumb piece 30 is pivoted at 31 on the upper portion of the handle 20, which latter is rigidly fastened to the inner side of the door. This thumb piece has an opening 32 therein, through which the lower end portion of the pull chain 29 extends downward and is fastened to the arm 27 previously mentioned.

With this construction, the door can be unlatched or unbolted from the outside, by moving the handle 26 downward. The initial pull will disengage the catch 4 from the opening 17, so that the door can be pushed inward, thus disengaging the overhanging bolt portion 18 from the flange 16 of the strike piece. Similarly, the door can be unbolted or unlatched from the inside, by pressing down on the thumb piece 30, as this will exert a pull on the rod 11 and chain 29 and disengage the catch from the strike piece.

If, during the opening and closing movements of the door, it is necessary for the bolt member 3 to pass under something, a pull on the chain 29, either by the handle 26 or the thumb piece 30, will pull the catch 4 downward to the limit of its downward movement, until it strikes the lower edge 33 of the slot 34 in the cross piece 8, and the lower edge 35 of the slot 7 in the case. This, of course, will pull the bolt member 3 itself downward a distance, until it is low enough to pass under any obstruction that may be in its path. The bolt 3 has slots 36 and 37 therein for the catch 4, permitting the latter to move up and down relatively to the bolt.

Thus a pull chain or cord bolt mechanism, or latch mechanism, is provided that can be operated or controlled from outside the door or window, as well as from inside thereof, whenever such is necessary or desirable.

The arrangement shown and described can be used on ordinary single doors that swing, of course, or on the swinging sections of sliding garage doors, or on other doors. As shown, the swinging door 38 may be either a single or ordinary swinging door, or it may be the swinging section of sliding garage In any event, a swinging door or door section 38 is supported by the bolt 3 on the flange 16 of the strike piece, in closed position, so that the door will not sag in this position. The handle 26 is preferably swiveled to turn in the

bearings

22 and 23, so that this handle may be folded back against the outside of the door, for any purpose desired. For example, this would be necessary or desirable when the invention is used on the swinging section of sliding garage doors, in order to prevent the handle from striking the side of the building when the doors slide around the corner, so to speak, from the doorway, to a position close to the side of the building. The spring 9, of course, normally holds the thumb piece 30 and the handle 26 in raised position, the lower edge of the cross piece 8 forming a stop for the projecting portion 39 on the lower end portion of the bolt member 3, thus limiting the upward movement. It will also be seen that the portion 40 of the handle 20 may function as a stop to limit the upward movement of the thumb piece 30, thereby limiting the upward movement of the arm 27 and the handle 26 in turn.

If the door 38 is the swinging section of sliding garage doors, then a strike piece similar to the strike piece 13 may be fastened to or made integral with the body of a traveling door hanger (not shown), whereby the bolt member 13 may support the swinging door section in open position, as well as in closed position, and whereby the catch 1 may hold the door in open position as well as in closed position.

lVithout disclaiming anything, and without prejudice to any novelty disclosed, What I claim as my invention is:

1. In overhead bolt or latch mechanism for doors, the combination of a strike piece on the building over the doorway, a vertically reciprocating bolt member, a catch pivoted on said bolt member, a pull connection attached to said catch, a spring normally holding said catch and bolt member in raised position, said bolt member having an overhanging portion to rest upon said strike piece when the door is in closed position, and said strike piece having means for engaging said catch to latch the door in closed position.

2. A structure as specified in claim 1, said mechanism comprising a sheet-metal casing in which said bolt member is free to move up and down, said member having two ears, the casing having a slot for the two ears with which the bolt member is provided, forming a guide, and said catch being pivoted upon and between said ears.

3. A structure as specified in claim 1, said strike piece having an opening to receive an upturned end portion of said catch, said overhanging portion and upturned portion extending toward each other and disposed in the same vertical plane.

4. The combination of a vertically reciproeating bolt member for the upper portion of a swinging door, a strike piece for said bolt over the doorway, said bolt member having means to engage and overhang a portion of said strike piece when the door is in closed position, whereby the bolt member and strike piece co-operate to support and prevent sagging of the swinging door in closed position, and means for operating said bolt member up and down.

5. A structure as specified in claim 4, said bolt member having a pivoted catch for also engaging said strike piece to latch the door in closed position, saidcatch being disengageable downwardly from said strike piece by the initial downward pull on said bolt operating means.

6. A structure as specified in claim 4, said bolt member having a pivoted catch for engaging the strike piece, thereby to latch the door in closed position, and means for disengaging said catch from the strike piece, and for pulling the bolt member downward.

Specification signed this seventh day of May, 1928.
