FASTENING DEVICE FOR DOORS OR WINDOWS.
SPECIFICATION forming part of Letters Patent No. 584,950, dated June 22, 1897.
Application filed Marsh 26, 1896. Serial No. 584,905. (No model.)
To nil 7.071.071?, t Utr/fg! corte/27171.:
Be it known that I, ISAAC V. MEAD, a citizen of theUnited States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Fastening Devices or Locks for Doors or I/Vindows, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.
This invention relates to fastening devices or locks for doors and windows; and the object thereof is to provide an improved device of this class which is simple in construction and operation and which may easily be connected either with a Window or with a door; and with this and other objects in View the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which- Figure l is a front view of a portion of a door and the adjoining frame, showing my iinproved fastening or locking device connected therewith; Fig. 2, a transverse section thereof on the line 2 2; Fig. 3, a view similar to Fig. l, showing my improvement applied to the sashes of a window; and Fig. 4, a transverse section thereof on the line 4 4., showing the `sashes in a different position.
In the drawings forming part of this speciiication, A representsa sect-ion of the frame of a door, and a the adjoining part of the door, and in the practice of my invention I provide a plate B, which is adapted to be secured to the frame of the door, and which is provided on its outer surface with an oblong seinicircular casing b, which is open at one end, and in the front and at one end of which is formed a slot or opening b2, at the inner end of which is formed a transverse notch or recess bs, and the plate B is provided beneath the casing b with an oblong slot or opening b4,
in which is placed a plate-spring O, which may be detachably held in position in any desired manner. I also provide a plate D, which is adapted to be secured to the door a, adjacent to the plate B, and which is provided on its outer side with a transverse notch or recess d, the sides of which project inwardly, so as to form a groove similar to that in a tongueand-groove joint, and formed on the plate D at the lower side thereof is a flange cl2, which is provided at its upper end with a shoulder or projection cl3, and I also provide a lever G, which is provided at its inner end with a head g, which is seinispherical in form, and which is adapted to be passed into the casing l) at one end thereof and to rest upon the spring O, in which position the lever G extends outwardly through the slot b2 in the side of said casing, and the lever G or the under side thereof is flared outwardly, so that the body portion thereof is substantially triangular in cross-section.
The operation will be readily understood from the foregoing description when taken in connection with the accompanying drawings.
By means of this device the door may be held slightly open, if desired, and in order to produce this result the lever G is swung outwardly and the door is opened, as shown in dotted lines in Fig. 2, and in this position of the parts the level` G passes through the notch or recess d and is locked therein by reason of the form of said lever and said notch or recess, the form of these parts in cross-section being substantially that of a tongue-andgroove coupling. This position of the parts is shown in dotted lines in Fig. 2, and whenever it is desired to lock the door it is only necessary to close the same and to drop the lever G into the position shown in full lines in Fig. l, where it will be held by the shoulder or projection d3 on the iiange or plate d2, and when it is desired to open the door the lever may be turned into a vertical position, as shown in dotted lines in Fig. l.
The spring O serves to hold the head g of the lever G firmly within the casing b, and this device constitutes a simple and effective lock for doors and one by means of which the door may also be held slightly ajar for ventilation and other purposes.
In Figs. 3 and 4. I have shown my improvement applied to Window-sashes, and in these iigures A represents the lower portion of the upper sash, and a the upper part of the lower sash. The casing b in this form of construc- TOO tion is provided with a semispherieal central portion b5 and also with the front slot b2, which in this case extends throughout the entire front thereof, and the semispherical ccntral portion b5 is provided with a transverse slot b3, and the plate D is provided with a notch or recess d, as shown in Figs. l and 2, and pivotally connected therewith is a cranklever K, each arm of which is provided with an upwardlyfdirected shoulder 7o, and the lever G is provided with a head L at its outer end and is similar in form in cross-section to that shown in Figs. l and 2. The lever G passes over the crank-lever K, and when it is desired to lock the sashes together the lever G is turned into the position shown in full lines in Fig. 3 and the parts will be securely locked in the closed position.
\Vhen it is desired to slightly lower the upper sash or raise the lower one, the lever G is turned into the position shown in dotted lines in Fig. 3, when the upper sash may be lowered or the lower sash raised, as shown in Fig. 4f, and in this operation the lever G cntcrs thenotch or recess d, as shown in Fig. 4 and as hcreinbefore described with reference to the construction shown in Figs. l and 2. In this form of construction thehead g of the lever G and the semispherical port-ion b5 of the casing l) constitute a ball-and-socket joint, and the spring C serves to hold the head of the lever in position, as hereinbcfore described.
It will thus be seen that I provide an effective fastening device or lock for windowsashcs, as well as for doors, and that the saine is simple in construction and operation, and also comparatively inexpensive, while being also well adapted to accomplish the result for which it is intended. It will also be apparent that changes in and modifications of the construction herein described may be 1n ade with- Out departing from the spirit of my invention or sacrificing its advantages, and I reserve the right to make all such alterations therein and modifica-tions thereof as fairly come within the scope of the invention.
It will be observed that the connection of the head g of the lever G with the casing I) of the plate 13 in both forms of construction constit-utes in effect a ball-and-socket joint, the lever G being free to swing` to the desired extent therein; and, having fully described my invention,
I claim as new and desire to secure by Letters Patentl. A fastening device or lock for doors and windows, comprising two plates as B and D, one of said plates being provided with an oblong hollow casing which is semicircular in form, and which is open at one end, and provided with a slot in one side thereof, which communicates with the open end and also with a transverse slot which communicates with the side slot, and a lever provided with a head which is mounted in said easing, said lever being free to swing in line with the plate or at right angles thereto, and the other plate being provided with a notch or recess which is ada-pted to engage with said lever, and the plate provided with the casing being also provided with a spring on w iieh the head of the lever rests, and the plate provided with the notch or recess, which is adapted to engage with the lever, being also provided with a crank-lever as K, over which the first-named lever passes, substantially as shown and dcscribed.
2. A fastening device or lock for doors and windows, comprising two plates as I; and D, one of said plates being provided with an oblong hollow casing, which is semicircular in cross-section, and which is open at one end, and provided with a slot in one side thereof which communicates with the open end and also with a transverse slot which communicates with the slot in the side, and a lever provided with a head, which is mounted in said casin g, said lever being free to swing at right angles to said casin g, and the other plate being .provided with a notch or recess, which is adapted to engage with said lever, and through which said lever is adapted to slide, and means for locking said levci and said last-- named plates together, substantially as shown and described.
In testimony that I claim the foregoing as my invention I have sign ed my nam c, in presence of the subscribing witnesses, this 20th day of March, 1890.
ISAAC V. MEAD.
