SASH-LOGK OR WINDOW-FASTENER.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed April 4. 1907- Serial No. 366.337.

it appertains to make and use the same,

reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention has reference to improvements in window or sash-fasteners; and, the present invention relates, more particularly,

to a novel construction of sash or window.

fastener or catch which is very simple in its construction and the parts of which can be easily and quickly secured in their operative positions upon the respective meeting rails of the lower and upper window-sashes.

My present invention has for its principal object to provide a sash-lock which is designed to provide an effective sashor window-fastening which can not be operated from the outside, by the insertion of a knifeblade, or other similar tool, in the space formed between the two meeting-rails of the upper and lower sashes of the window. v

A further object of this invention is to provide a novel, simple and operative construc-.

tion of sash-lock or window-fastener in which the various parts are readily adjusted and in which the locking-lever or arm, while in its operative position ready for enga ement with a holding or retaining post or ug, has an oscillatory or pivotal movement, is also capable of a slidable movement whereby the locking lever or arm can be withdrawn out of the pathof said post or lug, during the movements of the window-sashes, so. that the parts of the sash-lock or fastener will not lock and will not interfere with the raising and lowering movements of the windowsashes, until the locking-lever or arm is again forced in an inward direction into the sashlock casing andonce more brought into its oscillatory or pivotal relation. r

A further object "of this invention is to provide a sash-lock or fastener of the general character hereinafter set forth which is provided with a key-actuated deviceor means adapted by means of a key to be brought into a positively locked engagement with the holding or lockin lever or arm, when said lever or arm has con brought into holding or retaining engagement with the retaining post or lug, to prevent the oscillation or pivotal movement of the locking lever or arm until the latter is again brought into its unlocked and operative relation by means of the key.

Other objects of this invention not at this time more particularly enumerated Will be understood from the followingdetailed description of the present invention.

The invention consists, primarily, in the novel sash-lock or window-fastener hereinafter set forth; and, furthermore, this invention consists in the various arrangements and combinations of the devices and parts, as well as in the details of the construction of the same, all of which will be hereinafter more fully described and then finally embodied in the clauses ofthe claims which are appended to and which form an essential part of this specification.

The invention is illustrated in the accom' panying drawings, in which Figure 1 is a plan view of portions of the meeting-rails of the window-sa'shes, and my novel construction of sash-lock or fastener secured thereto, said view illustrating the vation or side view of the sash-lock or fastener, showing more particularly the fingerportion of the holding or retaining arm or lever extending from the front of the casing, and showingalso a key-hole in said front, said view being ,made on a reduced scale. Fig.14 is a view, similar to the view represented in said Fig. 2, said view showing the retaining or looking lever or arm in its relation when it is free to be moved back and forth upon a pivot-post, the lever or arm being represented in its actuated position,

when pushed in the direction of the arrow :1: by the operator, showing the holding end of the lever or arm disengaged from the holding or retaining post or lug,, for the purposes of moving either or both .fwindow-sashes, said view showing, also, in dotted outline, the normal initial position of the lever or arm when the pressure has been released therefrom, and when its holding end is in its retaining or holding engagement with said holding or retaining lug or post. Fig. 5 is a similar view of the same parts, said view, however, showing the retaining orlocking lever or arm moved into its outwardly withdrawn position,in which said lever or arm is held so as'not to interfere with the upward and downward movements of the window-sashes. Fig. 6 is a perspective view of a key which may be used with the sash-lock or window-fastener. Fig. 7 is a vertical section, taken on line 77 insaid Fig. 2, and Fig. 8 is a similar section, taken on line 8-8 in said Fig. 2. Fig. 9 is a transverse sectional representation, taken on line '9--9 in said Fig. 4; and Fig. 10 is a similar section, taken on line 1010 in said Fig. 4. Fig. 11 is a section, similar to Fig. 8 of the drawings, showing a pivoted holding dog in its raised position, prior to being brought into the position indicated in Fig. 2 of the drawings, for locking the retaining lever or arm in its immovable position. Fig. 12 is a perspective view of the holding Orretaining post or lug.

Similar characters of reference are emloyed in all of the above described views, to indicate corresponding parts.

R ferring now to the several figures of the drawings, the reference-character 1 indicates the meeting-rail of the upper window-sash, and 2 represents the meeting rail of the lower Window-sash.

The reference-character 3 indicates the retaining or holding catch or keeper, which consists essentially of a base or plate 4 provided at its respective ends with holes or openings for the reception of screws 5 by means of which the base or plate 4 is secured in its proper position 11 on said meeting-rail 1. Extending upwar ly from the rear edge of said base or plate is a wall 6, preferably provi-de'd with an enlarged or thickened portion 7 said wall being formed with a laterally exten'din part 8, which terminates preferably at the front edge of said base or plate 4. The said part8 is provided with an upwardly ex tending post or element 9 which is made with a holding or engaging portion 10 and has an angularly shaped edge-portion 11 which pitches from the point or free end of the post or element 9, downwardly and outwardly to .the end of the engaging or holding portion 10, substantially as shown more particularly in Fig. 1-2 of the drawings.

The reference-character 12 indicates the sash-lock or fastener, and the same comprises a suitable base or plate 13 provided with perforated end-portions 14, said base or plate being also preferably provided with 111" re'ceiving holes or openings 15. A suitabTe casing 'or shell 16, which is provided at its respective ends with ears 17 formed with holes or openings 17 which register with the holes or openings 15 in the end-portions 14, is placed upon the said base or plate 13, and permanently secured thereon by means of projections or lugs 18 which extend from the under sides of the ears 17 and are inserted in the lug-receiving holes or openings 15. The free ends of said projections or lugs 18 are then u set or rivet over, whereby the casing or shell 16 is permanently secured upon said base or plate 13, as will be clearlyunderstood. When thus secured together, screws 19 are passed through the other registering holes or openings 17 and 15 in the ears 17 and endportions 14 for securing these connected parts in 1their proper positions upon the meetingrai 2.

The shell or casing is provided in its rear face with an opening .20, and in its front face with an opening 21., a key-hole 22, preferably of the configuration shown in Fig. 3 of the drawings, being also provided in the front face of the shell or casing. Connected with and extending downwardly from the inner face of the upper portion 23 of the casing or shell 16 is a projection 24, the purpose of which will be presently more fully described.

From an inspection of the several figures of the drawings, it will be seen, that the said base or plate 13 is provided with an upwardly extending post or pivot 25, and 26 is a retaining lever orarm, which is formed with an elongated opening 27 arranged over said post or pivot 25, substantially in the manner shown. The rearward end-portion 28 of said lever or arm extends through the opening 20 of the shell or casing 16, and has an upwardly extending projection or element 29 which is adapted to be brought in frictional holding engagement with the rear face 30 of the angular engaging or holding portion 10, substantially as illustrated in Figs. 1 and 2 of the drawings. The said lever or arm has a narrow end-portion 31 upon its other end, said end-portion having a concave edgeportion 32 and extends from the opening 21 in the front face of the shell or casing, said end-portion 31 being made with a suitably formed finger-piece 33.

A suitable guide or retainer 34 is arranged upon the said base or late 12, in which is 'operatively held a coi ed spring 34, said spring being suitably compressed and having its respective end-portions arranged in holding contact between thefaces of the one wall 35 of the shell or casing and the side of the lever or arm 26, as clearly illustrated. The said base or plate 13 is also provided with an upwardly extending rib or projection 36, formed with a fiat side or face 37, and having upon its upper edge, at one end thereof, a suitably chamfered holding teat or projection 38. The said base or plate 13 is furthermore provided with an upwardly extending pivot-post 39' formed with an' en-' or ring-shaped end-portion 42 of a locking.

or holding dog or. pawl 41. In its under sur face the dog or pawl is made with a cham,.

bered portion 43, formed by the parts 44 and 45, substantially as shown in Figs. 8 and 11, said dog or pawl. being provided with an upwardly extending member 46 with which is connected a laterally extending arm or finger 47 formed at its free end with a slightly downwardly projecting holding lip or projection 48, said parts extending over and above the lever or arm 26, and under 0 rtain conditions being adapted to be brought in holding or locked engagement. with said arm or lever 26.

When the various parts of the sash-lock or window "fastener are in their relative positions indicated in Figs. 4, 9 and 10 of the drawings, the arm or finger 47 of the holding.

dog or pawl rests upon the upper edge of the rib or projection 36and against the chamfered teat or projection 88; and then a rearwardly extending arm or linger 48 is raised. a

sufficient distance above the upper surface of the lever or arm 26, and the part 45 is sufficiently removed. from the side of said lever or arm 26, that the oscillatory or pivotal move ments of the arm or lever 26 are'not interfered with. Thus,by pressing against the fingen piece 33 in the direction of the ar'rowxin Fig. 4 of the drawings, the lever or arm 26 swings upon the pivot or post '25, whereby the upwardly extending projection 'or element 29 is removed from its holding engagementwith the angular engaging or holding portion 10 of the catch upon said meeting-rail l, and the respective window-sashes can be raised or lowered, as will be evident. Upon the removal of the pressure from the fingerpie'ce otsaid lever or arm 26, the coils of the compressed spring returns said lever or arm to its normal initial position, indicated in. the dotted outline in said Fig. 4,.and when the window sashes are again brought into their closed relation, the end-portion 28 of the lever or arm 26 rides down over the inclined edge of the holding portion 10 of the catch, thereby slightly compressing the spring, which immediately forces the retaining or holding portion 29 of the lever or arm26 once more in holding or locked engagement with the portion 10, as soon as the end-portion 28 of the lever or arm 26 has cleared the lowest point of the inclined edge of said holding portion 10.

From an inspection of Fig. 5 of the-drawings, it will be seen. that the lever or arm 26. when the holding dog or pawl is in the position shown in said figure, is capable of a sliding movement, to entirely remove the endportion 28 and its projection or element 29 entirely away from engagement with the holding lug, post or "catch, upon the meetingrail 1. This is accomplished. by withdrawing the lever or arm. 26 outwardly in the direction of? the arrow y in Fig. 5, to theposition shown, so that the e'longatedopening 27 of the lever or arm 26 willnowhave the position shown in said Fig.5, withrelation to the post 25. In this position the lever or arm 26 will be retained, until again pushed inwardly to the position shown in Fig. 4, and is incapable of any pivotal. or oscillating movement, because the slightly compressed spring,.When in the position shown in Fig. 5, causes a binding or holding engagement between the fiat side of the body of the lever or arm 26 and the flat -face or side 37 of the rib orprojection 36, as, will. be clearly understood from an inspection of said Fig. 5. Thus it will be evident, that the windowsashes can be raised. and lowered without the necessity of operating the window-fastener or sashlocl which is of advantage when washing or cleaning the window.

When the retaining or holding dog or pawl, and the various parts of the sash-lock or window-fastener are in the positions in- .lnent, whereby its holding end-portion might become disengaged from the holding lug, post or catch 3, by the engagement of the side or edge of the rearwardly extending finger or arm 48 of the slightly lowered holding dog or pawl having been brought into a positive binding and holding engagement with the side of the lever or arm 26, and the insertion of a thin blade or tool be tween. the two meeting-rails'l and 2, and forced 'sidewise against the lever or arm 26, will be of no avail 'to produce a pivotal or oscillatory movement of said lever or arm 26, as will be fully understood from an inspection-of said Fig. 2 of the drawings.

QVVhen it is desired to unlock the parts, so as to be ableto produce the pivotal or oscillatory relation of the lever or arm 26 to remaining parts of the sash-lock or window? fastener, 21; key 49, seeFig. 6, may be employed for slightly raising the pivoted holding dog or pawl 41 from its locking position indicated in said Fig. 2 to its inoperative or disengaged relation to the lever or arm 26, shown in Fig. 4 of the draw ings; I To accome plish this movement,the"key 49 is provided at its inner free end with. a lifting tongue or lug 50, and extending from the side of the key, at a point back of'said tongue or lug 50, andin a plane'substantially at right angles to the plane of said tongue or lug 50, is another tongue or lug 51 which acts as a stop, substantially as and for the purposes to be presently more fully described.

' The tongued end-portion of the key isp assed through the key-hole 22, until its tongue or lug 50 passes beneath an opening 52 in the lower front portion 53 of the dog or pawl 41., see Fig. 11, and the tongue or lug 51 is brought in engagement with the side of the dog or pawl 41, as clearly shown in Fig. 2 of the drawings, which acts as a stop and properly locates the tongue or lug 50 in the chamber between the parts 44 and 45 of the holding dog or pawl.

A quarter-turn of key now brings the two tongues or lugs 50 and 51 in the relative ositions shown in Fig. 4 of the drawings, t ereby slightly raising or lifting the dog or pawl 41, so that its extension or finger 48 is removed from its holding engagement with the side of the lever or arm 26. By means of a slight pull upon the key in a forward direction, toward the front wall of the shell or casing 16, the lug or tongue 50 engages the inner face of the front portion 53 of the dog or pawl 41, whereby the latter is drawn from the holdin or locking position, indicated in Fig. 2 of t e drawings, to its raised and inoperated relation shown in said Figs. 4 and 5, thereby releasing the lever or arm 26, so that it is free to oscillate, as represented in said Fig. 4, for the purposes hereinabove described, or for drawing said lever or arm 26 into the fixed position indicated in said Fig. 5.

By a return quarter movement of the key, the latter may be withdrawn from the sashlo'ck or window-fastener, or it may be permitted to remain within the casing or shell 16 without interfering with the operative movements of the lever or arm 26, thesaid lever or arm being supported upon the upper edge of the rib or projection 36, and being prevented from being accidentally displaced therefrom by the chamfered holding teat or projection 38, as will be clearly evident. By simply pushing the key again in an inward direction, when the lever or arm 26 is in the dotted position indicated in Fig. 4 of the drawings, the finger 47 of the holding dog or pawl 41 rides upon and over the chamfered teat or projection 38, the holding dog or pawl dropping back into the position shown in said Fig.

2 of the drawings, and the mechanism of the sash-lock or window-fastener is once more held in its positively locked relation.
