GRAVITY SASH-LOCK.
Specification of Letters Patent.
Patented Feb. l5, 1910.
To all whom it may concern:
Be it known that we, .lol-IN C. lV allan: and (iro'r'rmnn Kilnissnnn, citizens of the United States, residing at Newark, in the county ot' Essex and State of New Jersey, have invented certain new and uset'ul Improvements in Gravity Sash-Locks; and we do hereby declare the following to be a t'ull, clear, and exact description ot 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 accomlmnying drawings, and to cha 1acters ot' reference marked thereon, which t'orm a part o't' this specification.
The invention has reference, generally, to iniprovements in windows, skylights, and the like, such as doors and shutters; and, the invention relates, more particularly, to a novel construction ot' gravity-lock itor use, preferably, with metal windows, skylights, doors, shutters, and the like the lock being especially adapted for use with a tlexible connection, such as a chain, and an intermediately disposed t'usible connection or link, for retaining the window, skylight, door, or the like, in an open position, but the lock acting automatically to close the open window, skylight, door, or the like, when the flexible connection is nnhooked, or when the fusible connection or link is melted in case otl excessive heat, due to tire.
The present invention has for its principal object to rovide in connection with a window, skylight, door, shutter, and the like, a simple and cheaply constructed, as vwell as a positively operating gravity lock which works by gravity to retain the window, or the like, in its closed position, but can be readily manipulated to open the window, or the like, all with a view ot entirely dispensing' with the use of any springs which are apt to become weak and useless, due to corrosion or when exposed to tire.
Other objects of this invention are simplicity in construction, and a reduction of the parts to a minimum, thereby providing a locking-mechanism in which the parts can not get out of order and are always in readiness to be operated, or to etleetively lock the window, or the like, when closed.
lith the various objects ot the present invent-ion in view, the invention consists, primarily, vin the novel gravity-lock hereinafter set forth; and, the invention consists, furthermore, in the novel arrangements and combinations oi" the, various devices and parts, as well as in the details ot the construction ot the same. all of which will be more fully described in the following specilication, and then finally embodied in the clauses o'l the claim which are appended to and which form an essential part ot the said specification.
The invention is clearly illustrated in the accompanying drawings, in which Figure l is a tace view of a metallic window-frame and a hinged or pivoted metallic window-sash arranged so as to swing in said window-trame, provided with a gravitylock embodying the principles of the present invention, and showing in connection therewith a flexible connection and a fusible link, the parts being represented in their normal initial position, when the window-sash is locked by means ot' the gravity-lock. Fig. 2 is a similar view ot the same parts, showing the window-sash unlocked and swung out into its opened position in the windowtrame. Fig. 3 is a transverse vertical section ot the portions of a metallic windowtraine and window-sash, showing in side elevation the lock-construction, with the locking-dog thereo2 in its locked or holding engagement with a part of the window-sash to retain the same 1n its closed position, said view being' made on an enlarged scale. Fig. 4l is a similar view of the parts represented in said Fig. 3, with the parts of the lock in their disengaged positions, just prior to the swinging-out movement of the window-sash, said view being made on a larger scale, than that ot' Fig. 2. Fig. 5 is a View similar to that represented in said Fig. 4t of the drawings, but showing' the positions of the respective parts otE the lock, prior to the swinging-in or closing movement of the windowsash. Fig. is a perspective View of the dog-releasing element or lever of the lock; and Fie'. 7 is a similar View of a frame or casing in which said dog-releasing element or lever is operatively arranged. Fig. 8 is a top or plan view of the sash-releasing dog and the trame or casing in which it is mounted; and Fig. 9 is a bottom view of the said parts. Fig. l0 is a transverse vertical section of the upper portions of a metallic window-trame and window-sash, and a side el evation of a slightly modified form of sashreleasing dog', the dog-releasinfr element or lever being, however, omit-ted Jfrom this view.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.
Referring now to the several figures of the drawings, the reference-character 1 indicates a metallic window-frame, of any usual construction, t-he same being provided with a hollow portion 2, forming a chamber, substantially as shown in the several figures of the drawings. In the lower wall or base 3 of the portion 2 is a suitable hole or opening 4l, and suitably secured upon this wall or base 3, by means of screws 5, or in any other suitable manner, is a suitably formed frame or casing 6. The latter is provided with suitably formed members or arms, as 7, and is provided with screw-threaded holes 8 for the reception of the screw-threaded shanks of said. screws 5. The said members or arms 7 form with the front-portion 9 of said frame-or casing an opening, as 10, the wall 11 of which may be made to taper downwardly, substantially as shown in Figs. 3, 4, 5 and 10 of the drawings. Extending' across the opening 10 is a pin or rod 12, said pin or rod having its end-portions suitably connected with said members or arms 7, and oscillating freely upon said pin or rod 12, and within the space or opening 10, is a window-sash releasing element or dog 13. This dog-is eccentrically pivoted upon said pin or rod 12, so that when the windowsash has beenV brought into its opened position, as will be hereinafter more fully described, the said dog 13 will hang vertically as indicated in Fig. 5 of the drawings. As shown, the said dog is made upon one of its port-ions, with an arc-shaped edge 14, as shown in the several figures of the drawings, and which may be left perfectly plain as indicated in Fig. 10, or may be provided upon a portion thereof with laterally extending projections or serrations, as 15, and
as clearly illustrated in Figs. 3, at and 5, of the drawings. The previously mentioned window-frame is also made with a downwardly extending' part, as 16, against which the upper portion of the windowsash is brought, as represented in said Fig. 3 Vof the drawings, when the window-sash is in its closed position.
In the present form of metallic window, the said sash which is pivoted in any suitable lnanner in the window-frame, is indicatedby the reference-character 17, the window-sash being made in its upper part with a hollow portion or chamber 18, which is ordinarily closed by the metal end-piece 19, shown more particularly in Fig. 2 of the drawings, said end-piece being suitably soldered or otherwise secured upon the metal strips 21 forming a part of the metal framework of the window-sash. ln its front faceportion the window-sash 17 is made with a suitably formed opening 22, while the said end-piece 19 is also provided with an opens 23. Suitably secured within the said hollow-portion or chamber 18, by means of screws 24, or other suitable fastening means, is a suitably formed frame or casing, as 25. This frame, as willr be seen more particularly from an inspection of Fig. 7, comprises an open rectangular frame-like element 26 which is provided with the screw-threaded holes 27. Extending downwardly from each longitudinal member of the said frame-like element 26 are suitable ribs or projections 28, said ribs or projections being formed with screw-threaded holes 29, and the rib or projection at the front of said frame-like element 26 being provided with an opening 30 which is bounded by a forwardly and downwardly tapering surface, as 31. As shown, thel said ribs or projections 28 are preferably of slightly greater thickness than that of the frame-like element 26, so as to provide suitable off-sets, as 32, at the front and rear of the respective ribs or projections 28, so as to properly fit the said frame or casing 25 in the upper portion of the chamber 18 of the window-sash, substantially in the manner clearly illustrated in Figs. 3, 4t, 5 and 10 of the drawings, being secured in. said position by means of the said screws 24. having their screw-threaded shanks screwed into the screw-threaded holes 27. W hen the said frame or casing 25 has been secured in its fixed position, the opening 30 in the front rib or projection 28 is directly back of the opening 22 in the front face-portion of the window-sash, as clearly shown in the said figures of the drawings.
Movably arranged within the open part of the said frame or casing 25, so as to be adapted to engage with the window-sash rej leasing dog herein-before described, is a suitably formed dog-releasing element or lever, as 33. This dog-releasing element or lever comprises a heavy head or member 34;preferably of the general configuration herein shown, although the shape of the said head may be departed from, and extending from the said head or member t and projecting into and through the previously mentioned openings 30 and 22 is an arm or finger 35 to the free end-portion of which is suitably attached, preferably in a hole or eye 36 for the purpose, a flexible connection 37, as a chain or the like, by means of which the lock-mechanism can be operated and the window-sash swung open and held in its opened position when a link of the said chain is hooked over a hook-shaped holding device, as 38, and as shown in Fig. 2. In any suitable portion of the said chain there may be placed a fusible connection or link, as 39, which melts due to excessive heat in case of fire and allows the window-sash to close of its own accord, as will be clearly understood.
Having thus described the general ar rangement and construction of the various parts ot the gravity-lock, we will briefly set forth its operation.
Suppose the windonvsasli to be moving in the direct-ion ot the arrow m, in Fig. 5, from its opened position to the closed position shown in Fig. 2), the window-sash releasing dog hanging vertically, as shown iu said Fig. The quick movement of the upper rear edge-portion of the window-sash against the said vertically hanging dog, immediately causes the dog to be swung or oscillated upwardly, practically in the position shown in Fig. 1l. .it the same time, the window-sash assumes its vertical and closed position in the window-trame, and the said dog in attempting to assume its former vertical position, drops partially .into the upper open part ot' the window-sasl'i, suhstantially in the manner illustrated in Figs. i?) and l0 et the drawings, causing a portion ot' the lower curved edge of the said dog, or one of the projections or serrations in the said curved edge-pmtion to effectively engage and bind with a portion ot' the open- Aframe or casing Q5 in the manner illustrated, so that on account o'f the eccentrically pivoted dog, and the weight thereof, the windowsash is positively retained in its closed position, against accidental opening oit' the same. In the meantime, the oscillatory dog-releasing arm or lever assumes its normal initial position, atJ rest` and as clearly indicated in said Fig. 3.
`When it is desired to open the windowsash, a pull upon the vflexible connection or chain moves the upper portion ot' the head of the dog-releasing device against the curved edge-portion of the window-sash releasing dog, thus causing the parts of the lock-mechanism to assume the posit-ions indicated in Fig. 4 of the drawings, and by continuing to pull upon the flexible connection or chain, the window-sash can be moved or swung open in the direction of the arrow y in said Fig. et, and retained in its open position in the manner shown in Fig. 2 ot the drawings.
From the foregoing description of the present invention, it will be clearly seen, that we have produced a simply constructed and efficiently operating gravity lock for the purposes stated, in which vthe use oit all springs is avoided so that the parts o't' the lock can not possibly get out ot order.
We are aware that some changes may be lnade in the general arrangements and combinations of the devices and parts, as well as in the details of the construction ot the said parts, without departing from the scope ot the present invention as set 'forth in the 'foregoing specification. Hence, we do not limit our invention to the exact arrangements and combinations of the devices and parts as described in the said specitication,
nor do we confine ourselves to the exact details ot' the construction otI the said parts, as illustrated in the accompanying drawings.
