BPECIFICATION forming part of Letters Patent NO. 357,701, dated February 15, 1887.

Application filed May 24, 1686. Serial No. 203,145. (No model.)

To all whom, it may concern.-

Be it known that I, EBER R. CROFUT, a citizen of the United States, residing at Newburyport,iu-the county of Essex and State of Massa.

chusctts, have invented certain new and useful Improvements in Windows; and I do hereby declare the following to be a full, clear, and exact description of 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 accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in window -sashes constructed and adapted'to turn pivotally in addition to the ordinary sliding movemenhand is designed to simplify the construction ofsaid pivotally-arranged sashes, and to render the operation thereof more positive and effective. A further object of the invention is to provide means upon which the sashes slide as they are raised and lowered, whereby they are prevented from rattling and are made perfectly air-tight.

The invention consists in the combination and arrangement of parts substantially as indicated in the drawings, and described and claimed hereinafter.

In said drawings, in 'which similar letters of reference areemployed to indicate corresponding parts, Figure l is an elevation of a window-sash partly sectionized. Fig. 2 is a longitudinal section of a portion of a sash and some of the adjacent parts. Fig. 3 is an elevation of the supplemental piece or lockingbar strip. Fig. 4 is a section of Fig. 3 taken through line 00. Fig. 5 is a perspective view of a device for repressing the locking-bar. Fig. 6 is a similar view of a binding-plate. Fig. 7 is a perspective view illustrating the relation of the device, shown in Fig. 5 for repressing the locking-bar, to said lockingbar. Fig. 8 is a vertical section of two binding plates in operative relation, and Fig. 9 is asection taken in the direction of line y, Fig. 2, through both window-sashes when down, and a portion of the window-frame.

' In the above-described drawings,a indicates the upright pieces or stiles of the sash; b, the detachable strips or supplemental pieces arranged between the stiles and the jambs b of the Window-frame, and c is a locking-bar arranged in recesses aoin the stiles and detachable strips respectively. The recess 0 is of sufficient depth to permit the depression of the bar below the top edge'of the said recess and allow the rotation of the sash, the opposite recess,a, being designed to allow the locking-bar to project thereinto so as to cover the joint between the strip and stile,and prevent the turning of the sash when the same is to be locked. The locking-bar is recessed at c", and passes through a hollow head, 6, which is secured to and countersunk in the strip 1), as indicated in Figs. 2 and. 3,and provided with a threaded projection, e, which turns within a correspondingly-threaded collar, 6, countersunk in the stiles at about the center of the recess therein. A spring, (I, is arranged between the bottom of the recess 0 and the back of the locking-bar, as shown in Fig. 2, to press said bar into the opposite recess, a, and across the joint,this being the normal position of the bar. A pin, m, passes through the head-spring and locking-bar, as indicated in Figs. 2, 4, and 7, and holds said parts in their respective positions.

To repress the locking-bar back into the recess 0, so that it clears the joint and leaves the sash free to be turned, I employ a device illustrated in Figs. 4, 5, and 7, which consists of an angle-piece, i, secured to or formed on a rod, h, which may project out through the side pf the head 6 and be provided with a finger-piece, or said rod h may be secured within a sleeve, 9, by a-screw, Z, as in Fig. 4. The angle-piece moves within the hollow head, and, as it is turned by its operating fingerpiece, engages with the back of the recess 0 of the locking-bar and forces said bar back into the recess 0', as in Fig. 2. While said bar is recessed at 0 still it isnot absolutely necessary. The recess, however, provides more space for the free movement of the angle-piece, and also permits said bar to project over the top and bottom of the head into the recess a.

When the improved device is applied to an ordinary window-frame, the detachable strips slide in the j ambs, as the ordinary window-sash; but to avoid the rattling of the sashes and exclude the air and dampness, which is not secured by the ordinary construction, I have de- ICO vised the construction illustrated particularly in Figs. 2 and S, in which 1) indicates a grooved or curved strip which is secured to the jamb of the window-frame, extending, preferably, the entire length of said jambs between the lintel and the sill. Oorrespondingly grooved o1: curved pieces b are sunk into the strips 1), said pieces being either sections arranged at intervals in said strips, as shown in Fig. 2, or a second continuous curved piece extending the entire length of the sash; or strips may be used, the sections being considered preferable because of their producing less friction. The grooved pieces provide ways upon which the sashes slide, and, as indicated in Fig. 8, overlap, providing a water-tight joint and also, practically, an airtight joint. \Vhen the sectional curved pieces are used,the entire length of the strips is grooved to allow the curved strip to project into the strips 1) and cover the joint between said strips and the jamb.

By means of the oppositely-arranged and co-operating ways or curved sections and strips, which are preferably made of metal, either cast or bent up into the proper form, the usual strip between the sashes may be dispensed with, as the said way prevents any lateral movement of the sashes, and also any rattling or shaking thereof.

To prevent the warping of the sashes and their shrinking away from the detachable strips 1), I provide metallic pieces 0, formed as indicated in Figs. 6 and 9, which are secured at the top and bottom of the adjacentfaees or sides of the stiles (t and strips b, and are provided with portions 1), which engage oppositely, as indicated in Figs. a and 9. Should the sashes have a tendency to shrink and to turn pivotally, I have provided on the adjacent faces of the portion 1) of the pieces 0 a teat or projection, 1), which engages with a depression in the opposite portion, of the cooperating piece 0, as indicated in Fig. 9.

As willbe understood,the curved or grooved ways may be applied to any window, and are not limited to the device herein shown.

Having thus described my invention, I desire to claim the following:

1. In a window, the combination of oppositely-arranged and cooperating curved pieces or strips adapted to be secured to a window sash and jamb, substantially for the purposes herein set forth.

2. In a window, the combination, with a curved metallic strip adapted to be secured to the window-jamb, of sectional curved metallic pieces adapted to be secured to the stiles of a window-sash and engaging with said curved strip, substantially as and for the purposes set forth.

3. The combination, with the j amb of a window and a curved metallic strip secured thereto, of a window-sash having grooves in the stiles thereof adapted to receive thecurved strip secured to the window -ja|nb, and sectional curved metallic pieces sunk in said grooves in said stiles and engaging with the curved metallic strips, substantially as and for the purposes setforth.

4. In a window, the combination, with the stiles of apivoted window sash, and a supplemental or detachable piece or strip arranged adjacent to said stiles, of engaging and co-opcrating pieces arranged in the ends of the adjacent faces of said stiles and strips, for the purposes set forth.

5. In a window, the combination, with the stiles of a pivotedwiudow-sash, and a supplemental or detachable strip arranged adjacent to said stiles, of engaging and co operating pieces secured to the ends of the adjacent faces of each of said stiles and strips, said pieces being provided with portions 2, having a teat, p,and a receiving-depression therein, substantially as and for the purposes set forth.

6. The combination, in a window, with the stiles of a sash and detachable strips, each of which is provided with oppositelyarranged recesses a c, a hollow head, 0, and a recessed locking-bar and spring arranged in said recesses and passing through said hollow head, of a pivotally-arranged angle-piece secured to or formed 011 a rod, h, projecting through said head engaging with saidlocking-bar, said rod 71. being provided with a finger-piece, substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 17th day of May, 1886.
