WINDOW OR DOOR BUTTON.

SPECIFICATION forming part of Letters Patent No. 462,474, dated November 3, 1891,

Application filed May 23, 1891. Serial No. 393,814. (Model-l T0 (tZZ whom it may concern:

Be it known that I, JOHN F. DINGEE, a citizen of the United States, residing at Bedford Station, in the county of VVestchester and State of New York, have invented certain new and useful Improvements in Locks; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 'in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to certain improve ments in turn-buttons for doors, gates, shutters, &c., by means of which the button may be locked and thus held from being turned from its holding relation with the co-operating catch.

The invention consists in the improved locking turn-button for doors, gates, shutters, and the like, and in the arrangements and combinations of parts, substantially as will be hereinafter set forth, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters indicate corresponding parts in each of the figures, Figure 1 is a front. elevation of portions of a door and door f rame, jamb, or post to which my improved devices have been applied. Fig. 2 is a sectional view of the same, taken at line 00. Fig. is a detail plan of a certain locking mechanism, viewed from the back; and Fig. 4 is a detail of a key which maybe employed for unlocking the turn-button.

In said drawings, a indicates the frame or door post 0rjamb;b, the door, gate, or shutter, and c the nosing of the catch;cl, the turn-button, and c the bed-plate on which the button is secured and has its pivotal bearings. The nosing is preferably inclined 011 the under side, as at c, and the button is correspondingly inclined, as at (1, so that when the said button is turned into engagement with said nosing there will be a wedging action, which will bring the door into proper relation to the jalnb, even though the former be warped,all as will be understood. On the under side of the button the same is hollowed out or chainbered, as at f, and the plate 6 is provided with a notch g beneath the button when the latter is in itslocked position. The chamber fis closed by a plate 7t, which on its inner side provides bearings '2' for a pawl or dog 7', and on its outer or lower side is provided with a pivotal lug 7t, by which the plate and the button carried thereby are secured to the bed-plate e, as will be understood upon reference to Fig. 2. The plate h is secured to the under side of the button by screws or other appropriate means, and is provided with an opening Z for the dog or pawl j, which coincides with the notch or recess 9 in the bedplate, so that when the buttonis turned pivotally the dog may drop into the said notch or recess and thus hold the button from f urtherturning, the button thus being locked. The dropping of the pawl is automatic and is occasioned by a spring on of any appropriate construction.

\Vithin the handle a of the button, or at the center of the button, the same is perforated and grooved to receive a slotted keycylinder 0, the slotp therein being adapted to coincide with the groove q of the button to allow the insertion of a key 0', Fig. 4. By turning the key the bits 8 thereon engage an inclined bearing t on the pawl or dog j, and thus raise the latter from holding engagem cut with the plate a, unlocking the button, so that it may be turned pivotally from engagement with the nosing.

In operating the device the slotted cylinder is turned with the'end of the key or otherwise until the slot therein is brought into coincidence with the groove, when the key is fully inserted into the look, so that when it is turned pivotally with the cylinder the bit 3 engages the inclined side or bearing of the dog or pawl and raises its catching or locking end from the recess g, so that the button may then be turned by the hand from engagement with the nosing.

By employing the end 0 of the button to engage the nosing the same may be turned back and forth without danger of locking. \Vhen the opposite end is employed, the catch will drop into engagement with the bed-plate automatically, unless held by the key, whenever the recess 9 is in coincidence therewith.

IOO

Having thus described the invention, what I claim as new is- 1. The improved tn rn-button herein described, having its opposite ends inclined to engage the nosing and provided with a lock adapted to be operated by a key to prevent the turning of said button, substantially as set forth.

2. In combination With the plate 2 and nosing 0, a turn-button centrally pivoted on said plate and having oppositely-projecting ends adapted to engage the nosing, and a lock operating to prevent the button from turning when one of said ends is in engagement witthe nosing, substantially as set forth.

3. In combination With the plate e and nos- 7' ing, a turn-button provided with a central handle and oppositely-projecting ends, a lock at the rear of said turn-button, and a key- JOHN F. DINGEE.
