SPECIFICATION forming part of Letters Patent No. 599,230, dated February 15, 1898. Application filed February 27, 1897. Serial No. 625.352. (No model.)

To all whom, t may concern:

Beit known that I, OSCAR FRorscHEa, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in W'indows, of which the followingr is a speciiication, reference being had to the accompanying drawings.

This improvement relates to that class of windows in which the sashes are pivotally connected with sliding cleats, so as to be tilted or reversed for the purpose of cleaning or otherwise; and the object of the improvement is to provide a window of this class that can be cheaply made, will be convenient in use, and not likely to get out of order.

To these endsthe invention consists in the peculiarconstruction, arrangement, andcombinations of parts hereinafter more particularly described and then definitely claimed.

In the accompanying drawings, Figure l is a vertical central section of a windowconstructed according to myirnprovement, showing the sashes closed in full lines and tilted in various positions in dotted lines. Fig. 2 is a horizontal section of part of a Window, on alarger scale,with both sashes down. Fig. 3 is an isometrical perspective View of one side of a sash. Fig. iis a horizontal section showing a modification of the pulley-stile. Fig. 5 is a vertical section of part of the stile of a sash. Fig. 6 is an isometrical perspective view of a hanger, chain, and pivot.

Referring now to the details of the drawings by numerals, l indicates the sill, 2 the casing, and 3 the pulley-stile, of the frame, the stile being provided with grooves 3', preferably of the form shown in Fig. 2 or Fig. 4, in which slide the cleats 4, set in grooves 6 in the sash-stile 7, in which last-mentioned grooves they are secured by screws 8, (see Fig. 5,) passing through holes in the cleats into the sash-stile. Surrounding the major part of the shanks of these screws are spiral springsQ, which partly set in holes lO, bored in the sashstile. Instead of spiral springs iat platesprings may loe used, as indicated at ll in Fig. in which case the holes will be unnecessary. Projecting through the cleats are pivots l2, having at one end plates 13, by which they are secured to the sashes, and at the other end `for the outer weight inside the casing. sides this the thick stiles increase the stiff- 7o grooves le!E to receive the hangers l5, having two hooks to catch into the chain 16, which passes over the pulley 17 to receive the sash- 55 ing toward the outside and forming the pro- 6o j ections 1S, which serve on the lower or inner sash to give space (ordinarily provided by the parting-bead) for the usual joint between the meeting-rails 19 20. (See Fig. l.) On the upper or outer sash it helps tofill the space usually occupied by the outer bead and covers up the outer part of the pulley-stile, which part is necessarily made wide to afford space ness of the sashes and form sufficient thick ness in the stile to allow of the formation of the groove for the cleats without weakening the stiles.

The pulleystile, if made as in Fig. 2, can 75 be cut across its full width, as indicated by the line 2l in Fig. l, and thus the pocket piece for the insertion of both weights can be removed in one piece for the full width of the stile, thus avoiding the necessity of vertical 8o on curved lines instead of on straight lines,

in which case the cleats should of course have the same contour on the contiguous parts. I should consider both these forms of grooves and cleats as equivalents of each other, and

where Irefer hereinafter to inclined edges 9o I mean to be understood as including both of these forms.

It will be observed that with the above constructions imparting-bead is required and no checks or beads inside or outside to hold the sashes in place, the bead 22 being merely used as a matter of finish and having no other function.

With the above constructions the sashes may be raised and lowered in the usual man- 10o ner, and if it is desired to reverse them for cleaning or other purposes the lower sash can be turned, as indicated by the dotted lines 23 in Fig. l, and the upper one, when it has been lowered and the lower one raised, can be turned in the position indicated by the dotted lines 24 in the same figure; or both sashes can be turned simultaneouslyin the position indicated by the dotted lines 25 in Fig. 1 for Ventilating purposes. This movement can be made in any position of the sashes. To make the sashes assume any of these positions, it is only necessary to push on the lower rails of the sashes. This will cause the cleats to rise over and out of the inclined edges of the grooves in the pulley-stiles, the springs between the cleats and sash yielding to allow this, and thus the sashes can be turned in any desired position. When it is desired that they shall assume their normal position, it is only necessary to turn the sashes to a vertical position, when the cleats will be forced by the springs into the grooves, and the sashes can be made to slide up and down in the usual manner. From this it will be seen that I have invented a very convenient window that is easily made and operated and one not likely to get out of order.

I am aware of theexpired patent, No. 30,095, issued to L. YV. Thickstun September 18, 1860, in which sashes are shown provided with strips that are moved in and out of grooves in the frame by means of spirallygrooved fastening devices; but these sashes are incapable of being swung on their pivots by simply pushing them, as they must irst have the strips withdrawn by turning the fastening devices before referred to.

I am also aware that it has been proposed to make a weather-strip on a hinged door with round edges, as shown in the Patent No. 399,413, issued to Jones March 12, 1889; but there is nothing in said patent to indicate that the inventor ever had any idea of using it in the manner shown in my improvement.

I am further aware of the Bolles patent, No. 554,231, dated February 11, 1896, in which there are shown sashes provided with yielding cleats working in the ordinary windowframes; but in this case the suspending means, instead of being attached to the pivots on which the sash turns, are secured to the cleats, so that the whole weight of the sash hangs upon them, which makes them comparatively hard to move, and therefore requires much stronger springs than is necessary with mine, in which the cleats are free to move and require but light springs to keep them in place, because my sashes are hung directly on the pivots, and there is thus but little friction to prevent the easy yielding of the cleats. Moreover, in the window shown in this patent the majority of the springs are necessarily arranged to bear on the grooves in the stiles, and are thus liable to mar and discolor the paint in the upper parts of the grooves, whereas in my improvement the springs are set between the cleats and the sashes and cannot, therefore, mar the paint.

I am also aware of the Rudolph patent, No. 207,305, in which the pivots are connected with the suspending-cords by means of the springs. This arrangement is objectionable, inasmuch as it requires the springs to be perforated to receive the pivots, which weakens the springs, rendering them liable to be broken, thus sundering the connection between the pivots and the suspending means. Moreover, as no spring can be used at the upper part of the sash for want of room, the sash depends for its action on the suspending-spring alone, which, as before stated, is liable to be broken. In myimprovement, on the contrary, the weakening or breaking of either one of the springs would have no effect, and I am thus able to combine the advantages of freedom from the friction of the springs, the plurality of springs, and the direct connection between the pivots and the suspending means.

What I claim as new is- 1. In a window and in combination with a sash having a groove in its sides, a cleat set therein having oppositely-inclined edges, springs operating to push said cleat outward set between the cleat and sash, al pivot fast on the sash and passing through the cleat, suspending means attached to the pivot, and a pulley-stile having grooves with oppositelyinclined edges and adapted to receive the oppositely-inclined edges of the cleats, substantially as described.

2. In a window, the combination of a sash having grooves in its opposite vertical edges, cleats set therein having oppositely-inclined edges, springs operating to push said cleats outward, arranged between the sashes and cleats and a pair of pulley-Stiles having oppositely-inclined edges and adapted to receive the inclined edges of the cleats, with pivots fast upon the sashes and projecting through the cleats to receive the suspending devices, substantially as described.

In testimony whereof I affix my signature, in the presence of two witnesses, this 26th day of February, 1897.

OSCAR FROTSCI-IER.
