SASH-LOCK.

Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed September 29, 1904. Serial Nei 225,434.

T0 all whom, t Tiener] concern.-

Be it known that I, VILLIAM A. DOUGLAS, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Sash-Locks; and I do hereby declare that the following is a full, clear` and exact description of the invention, which 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 the ligures of reference marked thereon, which form part of this speci-` fication.

The object of my invention is to provide a sash-lock which is automatic in its locking operation, simple in construction and of easy operation, and which is applied to the sash in such a manner as to he not only unobjectionahle, but entirely desirable.

In the drawings which accompany and form a part of this specilieation, Figure 1 shows a front view of a sash having my sash-lock applied, a portion oi' the frame, however, of the sash heing broken out to reduce the size of the figure. Fig. 2 shows a cross-sectional view of the same. Figs. 3 and 3 show two partial longitudinal sections or views taken in diii'erent planes. Fig. 4 shows a side elevation of thc lock with the front plate of the casing removed. Figs. 5 and 5h show longitudinal horizontal sections with the mechanism in each part operated to diiferent positions. Fig. 6 shows a modified form of construction with the rear plate of the casing removed. Figs. 7 and 7b show' longitudinal vertical sections of the same with the mechanism in each part operated to a dilierent position. Fig. 8 shows a plan View of the sliding catches employed in the modified form of construction shown in Figs. 6 and 'i'a and 7 b, together with the springs which operate the catches and the frame or fixed catch with which they engage. Fig. 9 shows another modied form ot' construction applied to a window-sash. Fig. Il) shows a longitudinal sectional view of the same with the parts in locked or engaged position. the same in the unlocked position. Fig. 12 shows the fixed catches applied to the window sill or frame. Fig. 13 is a cross-sectional view through the lock and sash.

Referring to the reference-iigures in a more particuiar description of the device, l indicates the box-like casing, which is adapted to be inlet into the sash-r`rame 2 and secured therein and is provided through its outer Fig. 1l shows Wali with a hand-opening 3. Mounted in the casing and arranged to stand normally partially in the hand-opening 3 or opposite to a portion of the hand-opening 3 is a movable or retiring handle 4, which includes downwardly-extending end portions s, which engage on the end walls of the case 1 and operate as a guide or slide for directing the movement of the handle. In the lower portion of the casing there is provided what might be termed an inner casing This casing as to its top 5 furnishes a closure for the lower side of the hand-opening 3 and at its ends provide openings or passages for the lower end of the sliding parts L?. In the ends of the inner casing 5 there are provided pivoted roliers 6. Attached to the iower ends of the sliding parts 4 and passing around the roller 6 is a hand or strap 7, preferaby of flexible met-ai. which extends and attached to the siiding catch 8. For drawing the catches 8 toward each other into engaging position with the casing or freine catch 9 there is provided a pair of springs i0, which are secured at their respective ends to hooks or other fixtures on the slides 8 at each end oi' the casing. The casing or frame catch 9 is a spear-head construction mounted and secured on a plate 11, adapted to he secured to a window-frame, either the sill or the top oi' the frame, as the lock is applied to the lower sash, the upper sash, or both, ot' a window.

It wiil he noted that the springs 10 draw the catches 8 at the opposite ends of the casing toward each other and into securing engagement with the frame-catch 9 and at the same time draw down the handle et. if the sash-lock is applied to the lower sash of a window to operate the same, the operator places his iingers in the hsnttopening 3 beiovv the handle tand iitts up. In so doing the handle is moved from th position shown in Figs. l, 2, and 3, whore the catches 8 are in securing position, to the position shown in Fig. 3, where the catches are released. Continued npward pressure on the handle 4 then serves to raise the sash and open the window. Ot' course when the sash-locks are applied at the top of the window on the upper sash a downward movement of the operators hand accomplishes the unlocking of the lock and the opening of the window in the same manner. Vl'hen the sashes are closed, the spearhead-frame catch 9 enters between the adjacent ends of the sliding catches 8, forcing them temporarily apart until the completely- IOO IIO

closed position is reached, when they are then moved into engaging and securing position.

In the modified form of construction shown in Figs. 6 and 7 a somewhat similar casing Q0 is provided, having in its face side the hand-opening 21 and within the casing provided with the verticall vmovable handle QQ. This handle, similar tothe others, is provided with end portions 22, which engage in the end of the case and direct the movement of the handle 22 and are provided with inclined projections 22". These pro 'iections are adapted to engage the upper ends, respectively, of the levers 23, pivoted in the casing at Q4. The lower end of these levers engage with the sliding catch-pieces lar to those heretofore described. catch-pieces Q5 are mostly received within the inner casing :26, the upper wall Q6 of which serves as a closure for the lower side of the hand-opening 21 in the case. The catches Q5 are drawn toward each other by springs 27, similar to those heretofore described, secured at their opposite ends to the sliding catches 25, respectively, in each end of the casing. These catches are adapted to engage with the similar spear-head-frame catch-piece 28 to that heretofore described. To move the handle 25 into its lower position when not forcibly moved otherwise, there is provided a spring 29, arranged in the upper portion of the case and preferably secured at 30 to the handle 22 and having its free ends adapted to engage the top wall ofthe case. This spring operating to force downwardly the handle 2Q serves particularly to move the wcdging projections Q2" out of their operative positions, so as to allow the catches 8 to slide toward their middle position and into engaging or securing position.

In the modilied form of construction shown in Figs. 9 to 13, inclusive, there is provided a construction which is adapted to a narrow Window-sash and which is adapted to operate in connection with two lixed hooks or catch projections provided on the window-frame. 1n this modified form of construction there is provided a box-like casing 40, adapted to be secured in a` recess in the window-sash in a somewhat similar manner to that heretofore described. In connection therewith there is provided a movable handle 41 in the nature of a loop, which at each end is provided with parallel portions 41". These portions 41*l are adapted to engage the end of the casing-and serve as slides to direct the movement of the handle. Tithin the casing the handle is provided with a crosshar 411. To this cross-bar is attached the one end of the straps or hands 42, which, passing' around the iixed rollers 43,

are attached at the other end to the sliding catch-pieces 44. These catch-pieces 44 are adapted to engage with the hook-like projection-catches 4o, mounted on a plate 46, adapted to be secured to the window-sill or Win- 25, which operate simi- These l dow-frame. Between projections on the adjacent ends of the sliding catches 44 there is introduced an expansion -spring 4i", which serves to force the catches 44 apart when not otherwise held and into engagement with the frame-catches 45. There are provided in the lower side of the main casing 4t) suitable openings to allow the catches 45 to enter. It will be noted that when force is applied to the handle 41 to move it in the direction that the sash will move in opening the window that the first operation is to draw back the catches 44, releasing the sash, while a continued movement will serve to open the window. In closing the window the inclined heads of the frame-catches 45 will serve to force back the sliding' catches 44, allowing the catch-shoulder to pass to a position where it can be engaged by the sliding catch 44.

It is evident that numerous other modiiications and changes in and from the construction herein described can be made without departing from the spirit of my invention.

That I claim as new, and desire to secure by Letters Patent, is-

1. The combination in a sash-lock of a casing, a handle movable inthe same direction as the sash, a locking-catch mounted in the casing, a roller journaled in the casing, a liexible connection between the locl ing-catch and the handle passing around the roller, a spring for moving the catch into locking position, and a fixed casing-catch with which the loching-catch is adapted to engage, substantially as set forth.
