Description
\ ED %TATE% FATE??? PIVOTAL DEVICE FOR TILTING SASHES.
Specification of Letters Patent.
Patented May 3%, 191%.
To all whom it may concern Be it known that I, LOUIS BOFIRD, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Pivotal Devices for Tilting Sashes, of which the structure of parts and in their combination for the purpose specified substantially as herein set forth and claimed.
in the accompanying drawings which form a part of this specification, Figure 1 is an elevation of a window showing fully the lower sash equipped with the present invention: Fig. 2 is a partially sectionized edge view of the structure in Fig. 1 and shows the lower sash tilted to the first au tomatic stop, three other successive stops thereof being indicated in dotted lines: Fig. 3 is a side elevation of one of the improved fixtures embodying all the features of this invention: Fig. is a plan view of the lower sash at the right side of Fig. 1, the jamb and stops being shown in section: Fig. 5 is a side elevation of that portion of the improved fixture attachable to the upper left edge of the lower sash, as seen in 1, showing the automatic catch which engages the coacting strip when the sash is closed and locks the sash to the stile at that side: Fig. 6 is an elevation of the pivotal portion of the improved fixture showing the stile strip tilted with respect to the sash strip and illustrating the detent that automatically stops the sash in predetermined definite positions: and Fig. 7 is a transverse section on line 77 through the fixture pivot and detent.
In disclosing the details of the invention reference will be made to the application thereof to the lower sash of a Window. In the drawings such sash is indicated at 8 and the sliding stiles at 9 and 10 to which it is pivoted to tilt as indicated in Fig. 2.
The fixture whereby the objects of this invention are attained consists primarily of the metal strips 11 and 12 pivoted together and having inturned edges 13 and 14: at opposite sides of the pivot. At the pivotal portions of the stripsare disks 15 and 16 respectively (of the same size and the one under the other, Fig. 6) and with respect to these disks the end portions of the strips are offset so that they have a scissors-blade relation and action about the pivot but the coacting edges beinginturned interlock instead of overlapping as in scissors. this abutting of the inturned edges (Fig. 4:)
that produces the air look when the sash is closed.
The strips of the fixture are attached to the sash and stiles by screws passed through holes 17. The stiles may be sawed from stock sash and the fixtures interposed or stiles may be especially provided as desired.
Between the disks 15 and 16,.a washer 18 isinserted and preferably brazed or otherwise secured to one of the disks. This washer furnishes additional thickness of metal for the pivot 19. It also separates the strips 11 and 12 sufficiently to provide for the requisite width of inturned edges to produce an adequate air lock. The Washers also serve to close the space between the inner ends of the interlocked edges.
The pivot 19 may be an ordinary rivet but it is preferable for the purposes of this invention to associate therewith a spring detent for the automatic stopping of the sash in certain definite positions and hold ing it in one of them till some one tilts it into another. Therefore the pivot is provided with a head especially formed for coaction with other parts of said detent, Figs. 3, 6 and 7. Said head is made rectangular and given a cap plate 20. A slotted sliding pawl 21 embraces said rectangular head and is confined against disk 16 by the cap 20. This pawl has a tooth 22 at one end and a spring 23 is interposed between the head and the other end. Said tooth enters a circular opening in the disk 16 and engages indentures 2 1 formed concentric with the pivot. The pivot 19 is rigidly fixed to the disk 15 as by means of a squared head (Fig. 7) riveted over onto said disk. When the disk 16 is rotated in-the tilting of the sash the indentures 24 are carried about the pivot and as the pivot head is fixed to the stile the tooth rides out of one indenture into another and will stop and hold the sash at any one desired of the several dotted posi- It is:
I tions' represented in Fig. 2, the number of said positions being determined by the number of indentures 24.
When the sash is closed it is locked automatically with its stiles and the air locks are tight as indicated in Figs. 3 and 4:. A simple lock for this purpose is formed by pivoting a catch 251 0 the upper portions of strips 12, said strips being attached to the sash. A spring 26 holds the catch in looking position. The hook of the catch plays in a notch in the turned-over edge of strip 12 and enters a corresponding notch in the cooperating strip 11 and hooks over the lower edge of the latter notch. By pulling out the handles of the catches 25 at opposite sides of the sash, the catches are unlocked and the sash tilted forward. The catches are provided with shoulders behind the edges 1% to close the notches in said edges.
The check beads on the sash are of course cut back at their ends to clear the stiles and to close the holes thus left between the meeting rails of the upper and lower sashes a piece of metal or other suitable material indicated at 27 is preferably attached to the upper end of each strip 11. These pieces 27 also have an extension across the strips 11 the thickness of the edge 13 to close the space between said strips and the sash.
Sashes equipped as above described are connected to their stiles with unusual rigidity and when closed and locked with their stiles operate perfectly as sliding sashes. lVhen unlocked from their stiles they operate perfectly as tilting sashes and because of the wide bearings at the pivots provided by the disks 15 and 16 they slide easily and evenly when in tilted position, the usual counterbalances being attached to the stiles as indicated by the cord or wire represented at 28.
The invention claimed is- A pivotal connecting device, for use with tilting sashes, consisting of metal strips constructed to turn one upon the other and to obstruct the passage of air between them, a pivot passed through one of said strips and riveted in place in the other, said pivot having a rectangular head provided with a cap plate, a slotted pawl having a tooth at one end and confined on the head of said pivot by said cap plate, that one of said strips which moves about said pivot having indentures to receive the tooth on said pawl, and a spring for forcing said tooth into said indentures.
In testimony whereof I have aiiiXed my signature in presence of two witnesses.
