SPECIFICATION forming part of Letters Patent No. 383,003, dated July l0, 1888.

Application tiled August Q6, lSS'I. Serial No. ill. (No model.)

.To [ZZ whom it 71mg/ concern/.L

iSe it known that l, BENJAMIN F. DETTRA, a citizen ol' the United States, residing at Read* ing, in the county oi Berks and State of .Pennsylvania, have invented certain new and useful -lmproreinents inr \Vindows; and I do declare the following to be a full, clear, and exact de seription of the invention, sueh as will enable others skilled in the art to which it appertains to malte and use the saine, reference bei ng had tothe accompanying drawings, and to the let ters andhgures of reference marked thereon, which t'orm a part of this specification.

llhis invention relates to windows provided with top and bottoni sashes, which are eon neeted at their meeting-rails in such a manner that thcymay be projected or drawn inward at their meeting line, the outside corners bo iup,` suitably supported iu the windowiranie.

The invention consists in the features ot' construction and combinations of parts hereinafter described and claimed.

Fignrel is an inside elevation ot a windowtrame with the combined sash in position. One side shows the finished appearance ofthe traine. lhe other side has the inside lining removed, revealing the sash-weights, pulleys, Sie., and the method otaltaching the cords to the sashes. Fig. 2 shows the sill and head-0f sash-frame ih section, the sashes closed tight against the inside head. Fig. 3 is the same view of traine, but with the sashes projected, showing;` very plainly the guide-strips,g1'oo\'es, cords, tite. Fig. shows a single strip in which the guidegrooves are formed, leaving sufficient material back of them to unite the strips.

lThis may be nsedagainst the pulley-piece of the saslrcasing, instead of the separate strips shown in other figures. Fig. 5 is an enlarged riew showing the top pulley-piece, the cord for the top sash rounding the pulley, and the sashzsupport attached to the end i' the cord. rPhe head-piece and pulley-piece ot' the sashl`ranre are indicated by dotted lines. Fig. G is s, plan View ol' the sash-support. Figs. 7 and 8 show the socket-piece attached to the corner of the sash, and Fig. 9 a plan olthe socketpiece alone. Y

in the drawings, A represents the head and (l the sill, l the back lining, and l the pulley-piece, of the sash-casing.

l? is a thin partitionpicce separating the sash-weights J and J3. This partition is not shown in Fig. i..

i3, mand H are the inside beads; B", guidevstrips; Bl, guidesgrooves, and B8 apertures for the pulleys and cords when a single strip is used, as in Fig. 4.

D is the lower sash, and E the upper, the latter being glazed with cathedral glass. Hinges l unito `the two sashes, the meetingrails of which are so beveled on the butting edges as to throw the outside parting line be- Jlow the inside line when closed, thus insuring a water-tight joint. A weather strip of rnbber or wood can be used instead, il' preferred. Fis a socketpieec attached to the outside corners of the combined sash,and is composed of a plate for securing it to the sash, anda square body, thaw-hole adapted to be set into the sash tlush. A hole, F, extends through the body, and is adapted to receive the round bearing i2 has a bifureated body, i', formed integral with said bearing, and is adapted to permit the saslrcordmhen the latter is slightly flattened, to be pushed. into the open jaws when the latof the sashsupporh'jwhich latter ter may be clinched upon it, thus securely ati.

The pulleys and pulley-pieces II are the saine as are ordinarily7 used, except that the topp'ulleypiece, being pushed up into the head et' the sash-frame, so as to allow the top sash to be closed against the head before the saslrsupport G-eouies iu contact with 'the pui` lcy, has the top of its screw-plate partly cnt oil'. 'lhe upper sash-cord, J, connects to the weight J', and the lower saslreord .to the weight J.

' Any suitable lock may be used to secure the sash when closed. I prefer one which shall lock automatically, and the whole of which will' bc concealed when the sash is closed, eX- eepting a suitable linger-piece, a notched plate, lli, being all that need beV attached to the sash. A lock substantially asldoscribed is already in use and may be readily applied.

My improvement may be attached to an old .window having countcijbalanee-weights with bntlittle trouble and expense. Ordinarily the top and bottom rails ot' the old sash are wide enough to allow sul'ieient reduction to permit one to be placed on top oi' the' other. rlhe muis Sunil iiml iiw` ibiuiii'wrm mi (im:
