WINDOW-FASTENER- Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed July 7,1905. SerialNo. 268,620.

, Fastener, of which the following is a specification.

My present invention constitutes an improvement upon .the window-fastener described in my pending application, Serial No. 237,835, filed December 21, 1904:.

My primary object is to make provision for the automatic locking of the window at any position within the limits of operation of the fastener, as well as for greater security of the fastener.

The invention is illustrated in its preferred embodiment in the accompanying drawings, in which Figure 1 is a broken elevational view of a window equipped with my improved fastener; Fig. 2, a broken plan section taken as indicated at line 2 of Fig. 1; Fig. 3, a broken vertical section taken as indicated at line 3' of Fig. 1; Fig. 4, an inner face view of the keeper, showing the head of the bolt entered in the keeper; Fig. 5, a perspective View of the bolt and its casing; Fig. 6, a perspective View of a fastening-plate for the bolt-casing; Fig. 7, a broken perspective'view of the bolt; Fig. 8, a section taken as indicated at line 8' of Fig. 3,-the bolt being secured, however, in such position as to enable it to slide within the keeper as the window is opened for ventilating purposes; and Fig. 9, a section taken as indicated at line 9 of Fig. 3.

1n the construction shownA represents a window-frame; B, a lower window-sash; C,

an upper window-sash; D, the keeper of my improved fastener applied to the upper sash,

and E the bolt of the fastener, movable in a casing E, adjustably connected with a sashplate E applied to the upper surface of the lower sash.

The keeper. is of elongated form and preferably is applied to the inner surface of a vertical member of the upper sash adjacent to the parting stop a of the window. When stamped from sheet metal, it preferably comprises, as shown, a bottom or inner plate d and a thinner top plate 03'. This is for convenience of manufacture. The two plates are firmly connected by rivets (1 so that the keeper virtually is integral in structure. The inner platethat is, the one next 'to' the sash has a wide longitudinal slot (i at one lateral wall of which are teeth d. The plate d has a superposed narrower slot (i thebordering metal forming flanges d, beneath which the head of the boltmay pass. When the keeper is appliedto the sash, the space represented by the slot d virtually forms a chamber for the head of the bolt. At the upper end of the slot (i is a V-shaped recess dbfor receiving and preventing injury to the locking-point on the head of the bolt under con-. ditions, hereinafter described, and near the lower endof the slot d is a socket or enlarged opening d, which is formed by cutting the flanges 03 to permit the bolt-head to enter. "At the lower end of the socket there is a shoulder (2, which projects slightly above the adjacent external surface of the keeper and is 1 internally beveled at d, serving the function of insuring that the bolt shall enter the socket when the window is being closed from a wideopen position. The keeper is. provided with perforations at, through which pass screws d, (one shown,) securing it to the sash.

The bolt E comprises a stem 6. equipped at its inner end with an elongated head e and provided at its outer end with'a thread 6 and a handle or winged put a", threaded to'turn upon the thread 6 and equipped with an inwardly-extending sleeve e, bearing against the outer end of the bolt-casing. A cotterpin limits the outward movement of the handle with relation to the stem upon which it is threaded.'. The bolt is encircled within the casing by a spiral spring e, having one end connected with the casing and the other with a pin a, passing through the bolt, so that the spring tends both to press the bolt inwardly toward the sash and to rotate the bolt on its axis. The bolt-head has a toothengaging point e and a wall-engaging point e", and the spring normally turns the bolt to a locking position, such as is indicated in Fig.

4, with the head confined between the teeth and the opposite wall of the slot 03 vThe bolt-head also has a beveled surface 6 which engages the beveled surface (1 to insure the automatic entrance of the bolt at the socket d when the window is closed from a wideopen positionif As shown 1n Fig. 9, the pin e serves by en.

gageinent with the walls ofthe casing to limit I the rotation of the bolt. vided with a longitudinal groove e, in which is confined by-a ring 6 a slide e, equipped with a finger-piece e. The casing E has adjacent to the bore which receives the bolt a The sleeve 6 is pro-- perforation for receiving the slide c. When the handle a is turned to its limit to the left, as viewed in Fig. 1, the channel '6 registers with the perforation e and the slide may be shoved in to key the sleeve to the casing, thereby securing the bolt in its angularly- .retracted position, permitting the window to ceiving screws a, providing for adjustment.

The plate E has a downturned perforate lug e receiving a horizontal securing-screw e. As the screws 6 pass also into the wood, it is evident that the bolt-casing is very securely fastened to the sash, preventing the possibility of prying the casing loose. The spaces between the perforations in the flanges e vary, and the pair of screws a may pass through any selected pair of perforations, thus providing for a differential adjustmeht enabling the greatest accuracy to be observed in adjusting the bolt with relation to the keeper.

The operation may be summarized thus: Assuming the window to be wide open, it may be closed without regard to the fastener, the bolt riding freely over the keeper until the socket is encountered, whenthe bolt enters the socket and becomes engaged with the lowermost locking shoulder of the 61 series, (indicated by g.) lln this position the sashes may be drawn together firmly by turning the nut e to the right. The bolt may be turned to the left against the force of its spring and the sashes adjusted to any desired degree of opening, the bolt rotating immediately upon release to the locking position. If desired, the catch 6 may, be employed to hold the bolt in its angularly retracted or rotated position, thus enabling the window to be opened within the limits of the fastener without the necessity of holding the bolt by hand. Of course the nut may be turned to the right to bind the sashes together at any desired degree of opening. When desired, the bolt may be forcibly withdrawn from the opening d, in which case the bolt will ride upon the keeper as the sashes are moved with relation to each other, permitting the window to be thrown wide open.

An important feature of the construction is that the bolt passes from the upper end of the keeper to the lowermost locking position without leaving the keeper, thus obviating danger of tampering with the device. Furthermore, the device operates automatically at alltimes to efliect a locking engagement regardless of the position from'which the window is closed.
