SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 345,273, dated July 13, 1886.

Application filed July 30, 1885. Serial No. 173,109. (No mrdel.)

To all whom it may concern:

- sash-locks, which are applied to the meet the sashes.

ing-rails of window-sashes for the purpose of fastening the two rails together when closed, in order to prevent the windows from being opened, as well as to prevent rattling of the sashes and the undue admission of air between In all such window-sash fasteners made prior to my invention the connection between the two sashes when the rails meet is either not made automatically, or, if made automatically, does not draw the two sashes together, and in all such devices the fastening is easily unfastened by any one on the inside of the window, or by any one breaking the glass and reaching his hand through.

The object of my invention is to provide a sash-fastener, one part of which is'attached to each of the meeting-rails of the sashes, which shall be automatic in its action to connect the two sashes and to draw the two meeting-rails together, which shall be simple in construction and compact in form, and shall afford a greater security as a look (not a mere catch.

"struction of the automatic fastener, which consists, preferably, of two spring-jaws pivotally connected with the upper sash, and which are provided with shoulders, below which is an opening adapted to receive and retain the bolt which is appropriately connected with the lower sash, and also in the various sub-combinations to be hereinafter morefully described, and definitely pointed out in the claims.

The principle of the invention thus consists in combining a key-lock with a sash-fastener, so that when the sashes are fastened it can be locked and unlocked only with a key; and the best mode in which I have contemplated carrying this principle into effect is in the form of device herein shown, although any other mechanical device accomplishing substantial- 6O ly the same intended result by the combination of a Windowsash fastener with a keylock will fall within the principle of my invention, and is intended to be covered by my broad claims.

In the drawings, Figure l is a front elevation of the device with the two parts thereof locked together. Fig. 2 is a front View, Fig. 3 a side view, and Fig. 4 a back view, of the automatic spring-jaws and their connections. Fig. 5 is a side view ofthe bolt and its connections. Figs. 6 and 7 are two vertical sections on the line as x in Fig. 5. Fig. Sisa top view of the spring-jaws and bottom plate,w'ith said jaws spread apart. Fig. 9 is a bottom 7 5 view of the bolt and its connections, with the bottom plate of the housing swung around on its pivot d. Fig. 10 is a detached view of the bolt-rod. Fig. 11 is a side view, and Fig. 12 an end view, of the bolt-socket or key-piece. Fig. 13 is a view of the key used with this form of locking device. Fig. 14tis adetached view of the sliding plate hereinafter described. Fig. 15 is a front elevation of the spring-jaws provided with a brace for holding said jaws open. A A represent two jaws, which are pivoted at a" a to the base-plate B. The adjacent faces of these jaws are at their upper edges sufficiently far apart to permit the introduction c. of the bolt 0, and the. said faces are then preferably beveled or curved toward each other for about half their height. They are then abruptly cut away, as shown, thereby forming the shoulders at a, below which the 5 space between said faces is sufficient to permit the bolt to rest While the jaws are in the position shown in Figs. 1, 2, and 4. Connected with said jaws are springswhich exert a con: stant pressure to hold the jawsin the position 10o right angle.

shown in said figures. The preferable form of -saidspring and the manner in which it is connected are shown in Fig. 3. It consists of a small coiled spring, I), inserted beneath the outer edge of each jaw, one end resting in a socket, a, in said jaws, and thrusts against the bottom plate, B, and said jaw to hold it in said position. The backs of the jawsA A are preferably beveled, as shown in Fig. 3, for the purpose hereinafter to be explained.

The base B consists, preferably, of a flat plate turned up on each side, the screws for fastening it to the window passing through the 0 represents the bolt, which is fastened at.

one end to said lower sash, preferably th rough the instrumentality of the casing or housing D, within which said end is shown to be sccured. The upper face of the bolt 0 should preferably be horizontal, and should meet the sides at an angle not much greater than a The bolt, as shown in the drawings, is square.

The spring-jaws A A, heretofore described, and attached to the upper sash, together with the bolt properly secured to the lower sash,

make in themselves an automatic window-fastener which prevents the window from being opened from the outside.

The lock part of my device, which 18 combined with and made integral with said latch ing device, is as follows: To the free end of the bol-t'O there is fixed aflanged disk, 0, the flange or rim of which (marked 0) has cut inj to it the slots 0 0. Upon the backs of the spring-jaws A A are fixed the projecting pins a a. The slots 0 c and the pins a a are so arranged that when the bolt passes between the jaws A A and the said jaws close, when the bolt has reached the enlarged opening between them, the pins a a pass through said slots when in their normal position as shown in Fig. 5, and lie within the circumference of the flange c. If the disk be turned so that the pins a a cannot pass through said slots, it is evident that the jaws cannot be opened,.and

the parts will be securely locked together until the slot-s in the disk are returned to their former position.

The preferable construction for accomplishing the above result is illustrated fully in Figs. 9 to 14, inclusive. That part of the bolt outside the housing D is preferably square. Just back of the square portion and within the housing is a cylindrical part, E, and back of that is an angular part, e, shown square inthe drawings, and somewhat larger in diameter than the part E, and back of that is another angular part, e, smaller than part c. The front and back walls of the casing D are perforated, the former to admit the bolt, and the latter to receive the bolt-socket or key-piece G. This key-piece is short and cylindrical, and has an annular flange, 9, upon its inner end, into which endissunk a socket, g,which receives and fits over the angular end 6 of the bolt. Two grooves, e, are cut into the bolt, beginning at the end 6 and running some distance into the cylindrical part E, and two corresponding grooves, y", are cut in the socket G from within, which grooves join together and continue through said piece, forming the slot or key-hole 1f, asshown in Fig. 1.

A plate, .T, (shown in detail in Fig. 14,) consists, preferably, of a plate bent up to form the sides 3" j, which act as guides, and has an orifice, j, which practically fits over the angular part eof the bolt 0. A coiled spring, L, surrounds said bolt and thrusts against said plate and the front wall of the housing D,and thus exerts a constant pressure to hold the plate J in the position shown in Fig. 9, when it fits over the angular part e of the bolt, and prevents said bolt from turning.

The parts above described are put together as follows: The key-piece G is first inserted from the inside of the casing D, the flange g preventing the same from passing through the wall thereof. The plate J and spring L are then placed in position, as shown, and the bolt 0 is inserted, passing through the spring and plate, and resting its end in the socket g in the key-piece G. A pin, Z, passes through the bolt within the housing D and holds the parts in position.

The operation of the device may be thus explained: As the two meeting-rails of the window-sashes come together the bolt 0 enters between the jaws A A, which open to permit it to pass, and then automatically close when it has passed below the shoulders av a, which shoulders prevent any upward movement, and the pins a 0. pass through the slots 0' c and rest within the disk-flange c. The front edge of the flange c at the same time bears against the beveled backs of the jaws A A, thereby drawing the two sashes tightly together. -A key, H, of the form shown in Fig. 13, for the form of lock herein illus trated, is inserted into the key-hole g. The arms h h enter the slots e" in key-piece G and bolt 0, respectively. The ends of the key strike the plate J and press it forward against the spring L until said plate is free of the angular portion 6 of the bolt. The key is then given a quarter-turn, and when the key is then withdrawn the plate J again engages with the part c and prevents further turning of the bolt. As the bolt was turned it carried with it the flanged disk c, and the slots 0' 0 took the position shown in Fig. 1. The pins a a, it is evident, can no longer pass through said slots, and the jaws cannot be opened. The bolt is thus securely held until said slots are returned to their former position.

The lock herein described is a modification of a new form of lock to be made the subject of a separate application for a patent to be made-before the issuance of the patent on this application.

Fig. 15 represents the spring-jaws, provided with a brace designed to hold said jaws apart and permit the use of both hands to open the window. The braec'N is pivoted in a groove in one of the jaws, and normally lies in the position shown in the full lines; but when it is desired to hold the jaws open it is turned forward and the jaws separated. The brace then falls between them and holds them in the position shown by the dotted lines until a slight blow from the bolt as it passes upward releases them and returns .the brace to its former position, as shown.

As security is one of the principal objects of my invention, it is desirable to have the parts attached to the window-sashes in such a manner that either part cannot be removed while the fastening is locked. This I accomplish with the jaw part by providing a screwhole in the bottom plate, directly beneath the opening between the two jaws, and so pivoting thejaws that when open, as shown in Fig. 8, a screw can be inserted and fastened to the sash. It is evident that when the bolt is be tween the jaws said screw is inaccessible. The same result is accomplished with the other part by pivoting the housing D by means of the pivot d to a bottom plate, K, in which are the screw-holes it It, and through these screwholes the screws pass which fasten the same to the sash.

M represents a flat spring lying transversely across the plate K. One end of said spring M is secured to the upper side of the plate K, and near one edge thereof, and the spring extends across said plate to the other edge thereof. Upon the upper side of the free end of the spring M a nipple, k preferably of inverted shape, is secured. Into the lower edge of the side of the housing, adjacent to the free end of the spring M, a longitudinal groove, 11, is out, corresponding in shape with the nipple k". When the housing D is closed over the plate K, the spring M forces the nipple is into the groove (1. Thus the plate K and housing D are held together against any accidental force to displace them.

As it is sometimes necessary to remove the sashes, the pivoting of the housing to the bottom plate serves this additional purpose, that it enables me to swing the bolt around out of the way, and thus facilitates the passing of the sashes.

In order to add strength to the connection between the bolt andvthe sash, which without the following devices might be severed by the mere breaking of the pivot d, I provide the front {face of the housing D and of the plate K with the projections d respectively, which projections dovetail together, as shown, and serve the double purpose of strengthening the device and forming a stop tolimit the motion of said housing and plate.

In the form of device herein shown two spring-jaws are used but the same result could be accomplished by the use of only one jaw, the parts otherwise being arranged in substantially the same manner as herein shown and described; but I regard the use of only one jaw as a mere inferior equivalent of the in vention herein described and claimed.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is v i 1. The combination of a pivoted spring jaw or jaws secured to the upper sash, a bolt secured to the lower sash and automatically engaging with said jaws to hold the sashes together, and a lock to prevent said bolt and jaws from being separated without the use of a key, for the purpose set forth.
