CHARLES S. SWIFT, 0F NEW YORK, N. Y.
'WINDOW-STOP.
Specification of Letters Patent.
Patented Mar. '7, 1916.
Application led November 8, 1915. Serial No. 60,216.
To all whom it may concern.'
Be it known that I, CHARLES S. SWIFT, a citizen of the United States, and a resident of New York city, borough of Manhattan, in the county of New York and State offNew York, have made and invented certain new and useful improvements in Window- Stops, of which the following is a specification.
This invention relates to a locking mechanism for windows, the object of the invention being to provide a simple but effective device of this class which will lock the upper and lower sashes of a window against opening beyond a certain limit, and wherein the locking mechanism is of neat and simple appearance, comprehending but few parts, and of such design and arrangement as to not in any way mar or detract from the sightly appearance of the window to which it is secured.
A further object is to provide a locking mechanism adapted to accomplish the aforementioned ends, wherein the mechanism is so arranged that it may be applied with equal facility to windows either in the course of construction or to those already completed.
A further object is to provide a locking mechanism which may be swung from its operative position and when so located does not in any way interfere with the free open'- ing and closing of the window sashes, being held out of contact therewith. The locking mechanism is further so arranged that, when in its operative position, it is positively held in suoli location, so that there is nok danger or likelihood of maliciously inclined people releasing the locking mechanism either whenl the sashes are partialiy raised and in their partially open positions, or when the sashes are entirely closed.
@ther objects and advantages will appear as the description proceeds, wherein it is to be understood that changes in the precise embodiment of the invention, and with regard to proportions and minor details, may be made without departing from the spirit of the invention.
The preferred embodiment of my invention is disclosed in the accompanying drawing, wherein Figure lis a fragmental view in perspective of a window comprising upper and lower sashes, and to which mv novel window locking mechanism is applied, the sashes being illustrated in their open and limited positions, and held against further opening by the locking mechanism; Fig. 2 is a detailed view of the locking mechanism, and
.brings out the simplicity vof the same, as
tion of the upper sash, 'the same being equipped with a runway plate, with which the pivoted frame of the locking mechanism is adapted to engage; Fig. 5 is a view in section, taken on the line w of Fig. 4; Fig. 6 is a view in section taken on the line 6-6 vof Fig. 4; and Fig. 7. is a fragmental view of a slightly modified form of runway plate.
Referring specifically to the several views, the window-frame l0, including the stiles 11, is provided with the upper and lower window sashes l2 and 13, respectively, and,
.as thus outlined, represents the conventional .type of window.
The upper sash l2 is formed with the side rails 14:, and the part-- ing rail l5. The lower sash includes the side rails 16 and the parting rail 17, it being to these side and parting rails of the sashes -that my improved locking mechanism is .adapted to engage and limit the degree to which the window sashes may be opened.
The locking mechanism is formed with the supporting base 18, through which extends suitable openings 19 for the reception of holding screws, and by means of which latter the base is rigidly secured to the stile 1l of the window-frame, and at a point directly opposite the positiony of the parting rails, when the window sashes are in their closed positions. The base is formed with the overhanging loop 20, through which and through the base extend the alined openings 21 for the fixed reception of a pin Q2, which acts as a pivotal mounting for a locking frame 23. Y
The locking frame, which is, for economical reasons, preferably formed from a single piece of metallic rod, is substantially U- shaped, and is formed with the spaced arms 24-25, which are connected at their one` extremitiesby the cross member or stop 26. The arm 24, which acts as a supporting arm, is pivoted at its lower extremity 27 to the base 18, so that the entire locking frame ics upper edge 24% of the supporting arm contacting with the inner surface 20 of the overhanging loop, which thus holds the armspaced away from the side rail of the window sash. r
Y The spacing of the arms 24-25 is slightly greater than the width of the parting rail 17 of the lower sash, so that it may be contained therein, and be restricted in its movement while so positioned by the cross member or stop 26. The free arm of the locking frame 23 is provided at its lower extremity with the outwardly turned neck 27, which enlarges atA its outer extremity to form the head 28, the connection between the head and neck defining the ledges or shoulders 29. The side rail 14 of the upper sash is provided adjacent its lower extremity with the runway plate 30, preferably countersunk therein, and thus extending flush with the outer surface thereof. rI`he runway plate, as indicated by its name, is provided with the slot or runway 3l extending longitudinally thereof, the length of which determines the degree or extent to which the upper sash may be lowered and opened. The runway or slot 3l is of restricted width, so as to nicely receive the neck 27 of the locking frame therein. rIhe lower extremity of the slot communicates with the wide recess 32 which is of such width that the head 28 of the locking frame may pass therethrough. As the locking frame is Yswung into its raised and operative position, the passage of the head ofthe locking frame through the recess 32 brings the neck thereof into alinement with the slot or runway 31, allowing the upper sashwith the runway plate to be lowered, the shoulders or ledges 29 contacting with the rear side edges of the slot 31, and thus preventing the locking frame from becoming detached from the runway plate while` the upper sash is in an open position. In this connection, it is to be noted that the upper sash is provided with a slot or channel 33, allowing for the free passage of the head behind the runway plate. l n
With the locking mechanism so constructed, it will be readily apparent that the locking frame is held in its operative position by either or both the upper and lower window sashes, when the same are in their open position, so that the locking mechanism canthe wide recess 32, "pawl moves across and partially closes the not be released until both window sashes have been closed, the arm 25 of the locking mechanism preventing the releasement of the locking mechanism when the lower window sash is raised, and the head 2S and the runway plate 30 preventing the releasement of the locking frame when the upper window sash is open.
In order to prevent the locking mechanism from being maliciously swung or moved from its operative position when the window 'sashes are closed, as might be accomplished by the insertion of a thin instrument between the parting rails, I provide a pawl 34, which is resiliently forced across a portion of the recess 32 by the spring 35. rlhis pawl is pivoted at its outer extremity 36, and moves within a chamber 37 provided therefor. The pawl is thus properly housed, and does not interfere with the free movement of the upper and lower sashes. he head 23 of the locking frame is pointed and beveled, so that, as it strikes against the spring-pressed pawl 34, it moves the same to one side, allowing the head to pass through after which time the said recess and prevents the accidental or malicious withdrawal of the head therethrough. It will, therefore, be apparent that no amount of shaking or manipulation of the window sashes can jar the locking frame from its operative position, as it is necessary to first move the spring-pressed pawl from its locking position.
The form of runway plate illustrated in Fig. 7 is provided with the elongated recess 32, of suiiicient length so that the arms 24.-25 do not have to be contracted prior to their being swung outwardly. In this nform of runway plate, a single spring 40 is rigidly secured to the runway plate and acts as a resilient pawl, so as to prevent the head 28 of the locking frame accidentally swinging in an outward direction and becoming detached from the runway plate.
Vhat I claim is l. A locking mechanism for windows comprising a frame; means for pivotally securing the same to the window frame, said frame including an upwardly extending arm projecting above the parting rail of the lower sash when the latter is in its lowermost position; a cross member carried by said arm and spaced a distance above said parting rail and limiting the movement thereof; means carried by the upper sash and said cross member holding said cross member in position above the parting Vrail of the lower sash and allowing said upper sash restricted movement.y Y
