4 Claims.
The invention is designed to provide a sash fastener of economical construction easy to operate and possessing durability and effectiveness in use.
The invention consists in the features and combination of parts hereinafter described and particularly pointed out in the claims.
In the drawing:
Figure l is a perspective View of the fastener.
Fig. 2 is a top plain view of the fastener.
Fig. 3 is a horizontal sectional View showing certain of the parts in plan.
Fig. 4 is a bottom 'plan View.
Fig. 5 is a front view of the standard or shell adapted to be fixed to the meeting rail of the upper sash.
Fig. 6 is a rear view of the section of the fastener which is adapted to `be attached to the meeting rail of the lower sash.
Fig. 7 is a transverse vertical sectional View through thepfastener.
Fig. 8 is a perspective view of the companion detent members.
In. this drawing, I indicates a shell adapted to be secured by screws at 2 to the meeting rail of the upper sash, and Ia represents a shell or casing adapted to be secured by screws at 2a to the meeting rail of the lower sash.
The shell or standard I is provided with an upwardly extending projection 3, the lateral faces of which are inclined and upwardly convergent, meeting along a line 4 at the upper ends of the said faces. This projection extends above the shell and is cast in one piece therewith.
The shell or standard I at its top and at each side of the base portion of this upwardly extending projection is provided with an opening or recess 6. These recesses open out to the front of the shell to permit the passage therethrough of detents or dogs 8, 8a carried by the shell or casing Ia, as will be referred to later. The shell I is also provided with a projection 9 extending downwardly, said projection being under and vertically in line with the upwardly extending projection 3. This downwardly extending projection has a flat front face in the same vertical plane with the front face of the upwardly extending projection, or, in other words, this front face of projection 9 is in the same vertical plane with the front face of the shell or casing I. This projection 9 is spaced apart from the rear wall I6 of casing or standard I, and it is rounded on its rear side forming substantially a cam surface sloping from the lateral edges 9a, 9a of the downward projection rearwardly to a meeting or high point 9b at the transverse center line of the shell.
The detent means 8, 8a pivotally mounted on the shell or casing Ia attached to the meeting rail of the lower sash provide a balanced locking ar- 5 rangement by reason of the fact that said detents are in a number of respects complements of each other, and are adapted to effect release of the fastening by simultaneously pressing their handle portions I2, I2@ towards eachother, or, in other 10l words, towards the transverse center line of the appliance.
These detents are pivoted within shell Ia upon a vertical pin I3 which is mounted in the shell in any suitable manner, vas vby riveting its ends 15 over upon the adjacent part of the shell. The handle or finger portions l2, I2a of these detents or dogs extend towards the front, and they are located in the same horizontal plane. They are normally in forwardly divergent relation to each other, being stressed for this purpose by a spring I4 coiled around the vertical pivot pin and having its ends bearing in recesses or depressions l5 in the inner side faces of the linger portions of the detents. These ends of the spring are confined in 25 place for proper operation of the detents by the shoulders I6 defining the recesses in the finger portions of the detents.
The rear portions of these detents or dogs are in the form of hooked portions II extending towards each other inthe same horizontal plane so that their extreme-'ends will normally meet. These hooked or convergent rear ends of the detents are adapted to embrace the downward projection 9. These extreme rear ends engage the 35 rounded or cam shaped rear face of said projection when the fastener is in locked condition. The rear hooked ends of the detents, under the action of the spring I4, ride up the cam shaped rear face of the projection 9, and thus draw theshells to- 40 gether, and with a balanced action the pressure of the dogs or detents in engagement with the projection due to the spring being substantially equally distributed between the two detents and the pressure of one detent being in a direction, opposite to that of the other detent. Pressure on the finger pieces or handles moving them towards each other will separate the rear hooked ends of the detents to disengage them from the rear shell I and its projection 9, and make them alignvwith 50 -the notches or recesses 6 so that then the lower sash may be raised or the upper sash lowered, the detent in this action finding free passage through the recesses 6.
As above stated, the finger or handle portions 55 of the detents are positioned opposite to each other in the same horizontal plane. This is true also of the rear hooked ends of the detents. The intermediate portions of the detents, however, are displaced relative to each other so that one lies above the other and thus both can be located on the same pivot pin. The upwardly extending projection 3 with inclined sides provides means by which the detents will be automatically operated as the meeting rails are brought together so that said detents will be separated at their rear ends to pass through the recesses 6 to get into position to snap together beneath the projection 3, and to engage the rear cam shaped face of the downward projection 9. The upwardly extending bevelled projection 3 provides cam inolines of sufiicient extent to insure a gradual spreading of the rear ends of the detents so that excessive strain and shock on the parts while they are being brought into locked position will be avoided.
The upper surfaces of the rear ends of the detents are in downward convergent relation to each other, generally speaking. More specifically speaking, they are of stepped formation, as at i8,
n said steps rising in opposite directions from substantially the meeting rear ends of said detent. This formation provides a compensating means for variations in the relation of one meeting rail to the other within certain limits. Here also we have a balanced action between the two detents, the stepped shoulders on the two detents being similarly disposed to the terminal portions of said detents, so that both detents will present their similarly disposed shoulders for engagement with the complementary part of the shell, according to the variations in the positions of the sash rails when the window is closed.
The projection 3 is connected with the rear wall of standard I and lies forward of this vertical plane of said wall. The under surface of this connection has opposite side portions which slope downwardly from the side edges of the base of the projection at 3a to the central face 3b. These side portions are stepped at 9c to cooperate with the stepped formation I8 of the upper sides of the ends of the detents.
The under sides of the extreme rear ends of the hooked portions of the detents are inclined or curved upwardly so that they will engage the upper point of projection 3 with certainty, despite any slight misalignment, and they will have an easy sliding action in respect to said inclined surfaces of said projections.
By my invention the sashes will be held against rattling and compensation will be provided for a sash that sags or in which irregularity may exist.
This application is a substitute for abandoned application Serial No. 637,306, filed October 1l, 1932, by Charles Francis Polack.
I claim:
1. A keeper member for sash fasteners comprising a support having a projection, the rear face of which is cam shaped having its high part at the transverse center line of the member, the upper part of said projection having a rearward portion providing an under surface to the rear of and substantially at right angles to the rear face of the projection, said under surface having opposite side portions which slope downwardly toward the center of the member, said rear cam shaped face being adapted to be engaged by a pair of latch members to draw the keeper member laterally toward them, and said downwardly sloping side portions being adapted to also be engaged by the latch members and afford a compensating means for variations in the relation of one meeting rail to the other.
