HORlZONTALLY-PIVOTED WINDOW.

SPECIFICATION forming part of Letters Patent No. 760,140, dated May 17, 1904.

A li ation fil d February 23, 1904:. Serial No. 194,75'7. (N0 model.)

To all whom it may concern:

Be it known that I, J osErH ELMER MoGnv- NESS, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Horizontally-Pivoted Windows, of which the following is a specification.

The invention relates to windows having the sash horizontally pivoted to strips on each side, which strips are adapted to be separated laterally from the sash and to travel longitudinally in the grooves of the window-frame; and the object of the improvement is to provide a simple pivotal connection between the sash and the strip by means of which the sash can be stopped or held in various positions of rotation. This object is attained by the arrangement, construction, and mechanism illustrated in the accompanying drawings, in which Figure 1 is a fragmentary side view of a window frame and sash, showing the pivotal connection in longitudinal section; Fig. 2, an enlarged longitudinal section of the pivotal parts in the strip with the sash rotated to show a cross-section of the pivotal parts therein; Fig. 3, a cross-section of the frame and sash on line 3 3, Fig. 1; Fig. 4, a detached perspective View of the swivel; Fig. 5, a detached perspective view of the sash-plate; Fig. 6, a detached perspective view of the strip-plate; Fig. 7, a detached perspective view of the spiral spring; Fig. 8, a detached perspective view of the washer, and Fig. 9 a detached perspective view of the swivel-pin.

Similar numerals refer to similar throughout the drawings.

The window-frame l is made in the usual manner with a groove 2 on each side for'receiving the respective sash-strips. The sash 3 is made less in width than the inside clear width of the frame, and the usual strips, as 4:, are pivoted on the side edges of the sash and are adapted to operate in the respective framegrooves. The adjoining faces 5 and 6 of the parts sash edge and side strip are provided with grooves 5 and 6 and ridges 5 and 6 having inclined sides, so that when thesash and strips are alined and brought together the respective ridges enter and fit into the corresponding grooves, as shown particularly in Fig. 3, and when the sash is rotated on the strips the ridges are forced out of the grooves and bear against the crests of the opposing ridges, thus sepa rating the strips from the sash according to the depth of the grooves, as shown in Fig. 2.

Each pivotal connection is composed of the sash-plate 7 the strip-plate 8, the swivel 9, the swivel-pin 10, the spring 11, and, preferably, the washer 12 and is best located in the transverse axis of the sash. The sash-plate 7 is countersunk in the side edge of the sash,where it is attached, as by the screws 13. The face of the sash-plate is grooved and ridged like the edge of the sash and on the rear side is provided the swivel-hub 14, in which is found the axial swivel-bearing 142. Across the rear end of this hub are provided the series of ribs 15, which have the inclined sides 16 and are preferably radially located, as shown. In front of the swivel-bearing and extending to the face of the sash-plate is provided the somewhat larger and likewise axial main bearing 17 of the pivotal connection.

The strip-plate 8 is countersunk in thesash side of the strip, where it is attached, as by the screws 18. The face of the strip plate is grooved and ridged like the side strip, and on the same side is preferably provided the pivothub 19, in which is provided the axial swivelaperture 20, and which hub is adapted to enter endwise and rotate in themain bearing of the sash-plate. The rear part of the swivelaperture is somewhat enlarged to form the socket 21 with the annular shoulder or seat 22 for the spiral spring 11, and on the rear side of the strip-plate are provided the lugs23on 1 each side of the spring-socket, between which lugs are formed the diametrically opposite guid e-slots 24, in which the ends of the swivelpin 10 are adapted to operate. The swivel 9 comprises the shank 25, having the transverse hole 26 in one end for the pinlO' and the head 27 on the other end, across the inner faceof which head are provided the grooves 28, preferably with inclined sides, which grooves cor respond in location and arrangement with ribs on the rear end of the swivel-hub of the sash-plate. The parts of the pivotal connection are assocket.

sembled by bringing the grooved and ridged faces of the sash and strip plates together, with the ridges of the one entered in the grooves of the other and with the pivot-hub of the strip-plate entered in the main bearing of the sash-plate, and the shank of the swivel is then entered through the swivel-bearing of the sash-plate and the axial aperture of the strip-plate to bring the ribs on the sash-plate hub into the grooves on the swivel-head, after which the spiral spring is placed around the.

swivel-shank against its seat in the strip-plate The washer is placed around the swivel-shank against the spiral spring,- and the swivel-pin is entered through the hole' in the end of the swivel -shank, withits side against the washer and its ends in the guideslots between the lugs on the strip-plate, in which normal relation of the parts thespiral spring is so confined or compressed that its energy acts to prevent a separation of the sash-plate from the strip -plate and of the swivel-head from the sash-plate hub.

With the parts of the pivotal connection thus assembled and the respective plates attached to the sash and the strip, one on each side of the window, and with the strips entered in the window frame grooves the sash is adapted to be rotated on its horizontal pivots by merely pulling or pushing the upper or lower end of the sash. In such rotation the side strips are of course separated from the edges of the sash in'the usual manner by the action of the inclined sides of the ridges on the one against the similar inclined sides on theother until the crests of the ridges of the one ride on the crests of the ridges of the other, as shown in Fig. 2, and the endwise movement of the swivel-shank in the axial aperture of the strip-plate necessary to accommodate this separation is permitted by the movement of the swivel-pin in the guide-slots between the lugs on the strip-plate to the position shown by full lines in Fig. 2, and as the swivel is held against rotation by the swivel-pin in the guide-slots the rotation of the sash also acts to separate the swivel-head from the sash-plate hub, which is accomplished by the action'of the inclined sides of the hubribs against the inclined sides of the head.- grooves and the endwise movement of the swivel-shank in the swivel-bearing of the sashplate, and the additional movement in the axial aperture of the strip-plate necessary to accommodate this separation is permitted by the further movement of the swivel-pin in the guide-slots to the position shown by broken lines in Fig. 2. When the swivel-head is thus separated from the sash-plate hub, the hubribs ride on the adjoining faces 29 of the head between the grooves until the ribs register with the next grooves, whereupon the action tion until the ribs are again forced out of the grooves, as before described, and in the same manner the sash can be rotated and stopped at various points.

When the sash and strips are alined, their edge grooves and ridges, as well as the ribs and grooves on the sash-plate hub and swivel-head, act to stop the sash against rotation; but when the sash is turned out of line with the strips the latter ribs and grooves act alone to this efiect, and in this latter action the swivel has an endwise movement independent of and in addition to the endwise movement caused by the separation of the strips from the sash. WVhile the sash is described as bearing both on the swivel and on the pivot-hub, either one or the other of these hearings can be used as a principal hearing; but it is preferred to make the main bearing on the pivot-hub, because of the greater freedom thus given to the swivel for its endwise movements.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In combination, a window-sash and a separable strip on its side edge, there being corresponding grooves and ridges on the adjoining faces, and a pivotal connection between the sash and the strip comprising a pivot-hub with an axial aperture on the one, a non-rotatable endwisesmovable swivel in the aperture having, a head with grooves across its inner face, a bearing in the other adapted to operate on the pivot-hub having .ribs with inclined sides on its end adapted to enter the head grooves, and a spring acting to move the swivel-head toward the pivot-hub.

2. In combination,a window-sash and aseparable strip on its side edge, there being cor' responding grooves and ridges on the adjoining faces, and a pivotal connection between the sash and the strip comprising an axial aperture in the, one, a non-rotatable endwise movable swivelin the aperture having a head with grooves across its inner face, a rotatable bearing in the other, between the one and the swivel-head having ribs with inclined sides on its end adapted to enter the head-grooves, and

a spring acting to move the swivel-head toward the one.

3. A pivotal connection for a window-sash and a separable strip comprising a pivot-hub with an axial aperture on the one, a non-rotatable endwise-movable swivel in the aperture having a head with grooves across its inner face, a bearing in the other adapted to operate on the pivot-hub having ribs With inclined sides on its end adapted to enter the headgrooves, and a spring acting to move the swivel-head. toward the pivot-hub.

4. A pivotal connection for a window-sash and a separable strip comprising an axial aperture in the one, a non-rotatable endwisemovable swivel in the aperture having a head with grooves across its inner face, a rotatable bearing in the other between the one and the the one, and means operated by the endwise movement of the swivel for retarding. the rotation of the bearing. i
