SPECIFICATION forming part of Letters Patent No. 731,847, dated June 23, 1903.

Application filed May 14, 1902 Serial No. 107,285. (No model.)

To all whom it may concern:

Be it knownthat I, ARGHIBALD L. BoLLEs, a citizen of the United States of America, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Window-Sashes, of which the following is a specification.

My present invention relates to various improvements in windows, and more particularly to supports for the sash. p I

A principal object thereof is to provide means whereby the sash may be revolved or turned inwardly for purposes of ventilation or toafford access to both sides of the glass in cleaning the same in order to obviate the I danger to which a window-cleaner is obliged to expose himself when cleaning windows arranged in theoldand well-known manner.

Another object is to provide means whereby the lateral play of the sash may be reduced to the minimum, so asto make astight a joint as possible, and wherebythe function of a weather-strip or wind-breaker toprevent the entrance of air through the joint into the house or apartment may be secured.

Another object is to improve the pivoting device wherebythe sash is revolubly mounted and also to. furnish. looking or fastening means between the sashes and the stiles or bars that constitute apart ofthe mechanism for allowing the turning of the sash; andother objects of the improvements will appear from the following description of the construction and operation. The invention therefore may be said to cone] sist,essentially, in the means hereinafter described foraccom plishin g thestated and other objects and also in the construction, combina tion, and arrangement of parts, substantially as will be hereinafter described and then pointed out more specifically in the claims.

In the accompanying drawings, illustrating e my invention,Figure l is a front elevation of a window-frameprovided with my present improvements, a part thereof being broken away and certain features being shown in section. Fig. 2 is a vertical transverse section of the same, the lower sash being represented as revolved or turned on its pivots. Fig. 3 is an edge view of the upper portion of one of the vertically-movable stiles or bars employed in connection with each sash. Fig. 4 is an enlarged vertical section of one side of a sash and the adjacent movable stile and represents in detail the structure and arrangement of one of the pivots and one of the locking devices whereby the sash and stile are locked together. Fig. 5 is a horizontal section of a part of the window-frame and the two sashes,the section through the upper sash and its accompanying pivoted stile being taken at the pivotal point and the section through the lower sash and its accompanying stile being taken at a point near one of the locks. Fig. 6 is another horizontal sectional view of a part of the window-frame and the two sashes the lower sash and its accompanying pivot-ed stile being shown as they appear when the sash is closed and the upper sash and its accompanying stile being shown as they appear in the shifted position which they occupy when the sash is revolved or turned on its pivot and the window open. Fig. 7 is another similar horizontal sectional view of a part of the window-frame and the two sashes and indicates especiallya modification of the form of the stile as to the flange that overlaps the parting-strip, each stile in thus differing from that in Figs. 5 .and 6, where one stile has no flange and the flange on the other is large enough to completely overlap the parting-strip. Fig. 8 is an enlarged detail side view of one of the pivots. 8 Fig. 9 is a side view of a modified form of the construction of the pivots. Fig. 10 is a sectional detail view showing a headless-screw device for supporting a sash not provided with weights. 90

Similar characters of reference designate corresponding parts throughout the different figures of the drawings.

The example of window-frame represented 5, 6, and 7, between which,as in guideways, the upper sash 8 and the lowersash 9 are arthis case having a flange, the construction in the drawings in connection with which my 5 provided with the customary strips or beads IOO ranged, so as to make the ordinary sliding movements necessary in opening and closing the window. It will be understood, however, that the frame shown is simply one example of window-frame and that my invention is not confined in its application to this style alone, but may be used either with adoublesash window, a single-sash window, a transom having a single sash, or with any of the manifold varieties of windows now in use in different locations and for different purposes.

In the vertical spaces between the beads or strips 5, 6, and 7, it being noted that 5 and 7 represent the edge beads and 6 the intermediate or dividing bead or partingstrip, as it may be called, I place verticallymovable stiles or bars, two being employed in connection with each sash, one on each side thereof, and these stiles or bars being preferably of the same length as the windowsashes with which they are connected. Thus the movable stiles are employed in connection with the upper sash 8 and the movable stiles 11 in conjunction with the lower sash 9. Each sash is preferably made slightly less in width than the distance between the beads belonging to the different uprights 3 and 4, so that when the sash is drawn in wardly or thrust outwardly it will not strike against the beads, but may be free to move. The vertical outer faces of each sash-frame are formed with longitudinal (preferably concave) grooves a, and the contiguous faces of the movable stiles or bars 10 and 11 are correspondingly shaped with longitudinal tongues, ribs, or ridges 1), (preferably convex,) adapted to fit neatly into the grooves a and to be susceptible of dislodgment therefrom at the time of the revolution of the window-sashes in the manner, for the purpose, and with the result which I shall hereinafter presently more fully explain.

It will be understood, of course, that either of the sashes, the upper or the lower one, may be turned or revolved independently of the other or that both of said sashes may be turned or revolved together, and it will also be manifest that when it is desired to revolve the lower sash it must be raised so that the lower side thereof may be freed from the strips or beads on the sill 2, and when it is desired to revolve the upper sash the same must be lowered, so that it may be disengaged from the strips or beads on the top lintel 1.

'lhe'sash- fraines 8 and 9, respectively, are pivotally connected with the stiles or bars 10 and 11 at the center thereof, (or at any other desired point,) as shown in Fig. 1 and more fully in the enlarged sectional detail of Fig. 4, and the mechanism of this pivotal connection I will now proceed to describe. In the vertically-movable stiles or bars 10 and 11, at a point near the middle of their length, (or elsewhere, if preferred,) is a recess or transverse passage 22, containing a tubular sleeve or block 12, having prongs 13, that are sharp and are driven into the adjoining face of the window-sash, as shown in Fig. 4. The end of the tubular sleeve 12 opposite to the prongs 13 is formed with a series of teeth, notches, or dentations 21. 14 denotes a tubular head having corresponding teeth, notches, or dentations 20, which are designed to engage and interlock with the teeth 21 of the tubular sleeve 12, said tubular head 20 having also an encircling flange 15 and in the outer end a central countersink or recess to receive the head of the securing-screw 19, which passes through the head 14'and the tubular sleeve 12 and is screwed tightly into the wood of the adjoining window-sash, as clearly indicated in Fig. 4, the head of this screw 19 being seated closely in the countersink and holding the flanged tubular head 20 with its teeth in close engagement with the teeth of the sleeve 12. One portion of the recess 22 is less in diameter than the remainder, there being'a right-angled shoulder between the two parts, and a sleeve 17 occupies the part of less diameter and has an integral flange 18, whichis seated on the rightangled shoulder alluded to. A spring 16 is coiled around the tubular parts of the pivot 20 and 12 and tensioned between the flanges 15 and 18, being thus arranged so that it exerts an elastic effect between the stile or'bar and the adjacent sash and which spring'is compressed when the sash revolves on its pivots. Thus it will be seen that the sectional pivot just described is fastened to the sash by having the prongs 13 driven thereinto. If desired, however, these prongs may be dispensed with, and in lieu thereof the tubular sleeve 12 may be provided with integral ears or plates 23 23, (see Fig. 9,) having screwholes 24, through which screws may pass for the purpose of firmly attaching the pivot to the sash.

The window-frame is provided with the usual sash-cord pulleys 35, over which the chain or support 29 runs, there being attached to one end of said chain aweight 34, asshown in Fig. 1. The other end of the chain is attached to the sliding stile or bar 10 or 11, as the case may be. The construction of the attachment may vary within wide limits, and I do not wish to be restricted to any particular way. By referring to Figs. 3 and 4 it will be seen that the movable style 10 is provided near its upper end on one side with a longitudinal groove 27, which runs as an open groove for a certain distance and is continued by a passage 30, which leads into a recess 28. By passing the chain or cord 29 downwardly through the groove 27 and then through the passage 30 its end within the recess 28 can be knotted or provided with some terminal ball or other device larger than the size of the passage 30, and thus a connection may easily be made between the chain or support and the movable stile. It will be perceived thatwhere such weights are used the window-sashes are supported entirely and solely by the vertically-movable stiles or bars to which they are pivotally connected and that these stiles or bars are provided with the customary counterbalancing weights or cords and that consequently my invention is not limited to any particular form or construction or arrangement .of these parts, and I am therefore free I to make such alterations or modifications therein as may fairly come within the limits of the present invention.

Referring to Figs. and 6,'it will be ob:

served that one ofthe vertically-movable stiles or bars and 11 (in these figures the stile 10) is provided with a longitudinal flange 25,which overlaps the parting or dividing strip or bead 6 on the uprightsof the window-frame. The parting-strip has right-angled corners, as

is customary, and the rabbet under the flange is correspondingly of a right-angled character in order that there may be a neat fit over.

the movable stile 10 to move towardthe uprightin a straight line until it strikes it and until the flange 25 strikes and seats itself upon the dividing-strip 6. The purpose of havingthc flange 25 overlapping the strip 6 is to assist in making a tighter joint, whereby the entrance of dust and wind may be more If desired, the bars of both sashes, aslO and 11, may be provided smaller than the single flange 25as', for instance, the flanges26 26 in Fig. 7.

I have provided means for lockin g the mov-.

ablestiles or bars to the sash, so that the latter cannot be revolved on itspivotswhile.

said means are locked, and I will. now pro- The bar or stile 10 or 11, as the case may be, is

The recess 40 containsthe transverse pin 42. v The recess 41 contains a suitably-shaped hook 43, mounted therein and susceptible of being vibrated upon its pivot from the position shownin dotted lines in Fig. 4, Where it is completely within the recess 41, to the position shown in full lines in the same figure, where it has been revolved over into therecess 40 and caused to embrace q the stationary pin 42 forthe purpose 'of looking the movable bar 10 to the. sash 8. The

hook 43 issupported by thepin44, a part of which is square in cross-section, so i as to engage a square opening in the inner end of hook 43. The inner end of the pin 44 is driven into the wood of the sash, as shown in Fig. 5, and its outer end is provided with a slot 45 for the engagement of a wrench or key for rotating, and thereby shifting, the hook 43 in looking or unlocking. The outer slotted end of the pin 44 lies within a suitable passage provided therefor in the sash, and in order to protect the end of said pas:- sage I preferably let into it a small flanged sleeve 49. There may be any number of these locking devices. Each sash may have one or more, or in a double-sash window one sash only may have the locks and the other not. A convenient number is two on each side on each sash or eight for the entire window. By referring to Fig. 1 the arrangement of eight is indicated, and it will be understood that in order to lock the movable bars to the sash the attendant needs only to use his key deftly and quickly at the eight points shown, the result of which will be to quickly cause all the locks to engage with their respective pins or to disengage therefrom in unlocking.

In case of a revolving window not provided ,with cords and weights-as, for instance, sin-.

gle-sash Windows, transoms, andthelike, where'the bead or strip on the sill does not interfere with the revolving of the window on,

its pivot-it is found desirable to provide some means for supporting the sash, andfor this purpose I utilize a screw or screwtl1readed pin, (shown at 47in Fig. 10,) the same not, having a screw-head, but having .a slot for the application thereto of a wrench or screw driver, and this headless screw or pin is screwed into the side upright 3 of the windowframe and projects into a tubular passage or recess 48 in the stile or bar 10. Obviously this passage 48 may be located above or below the window-pivotin fact, may be situated at any point. Said passage may be provided with a bushing or sleeve, if desired.

Having thus described my invention,what

ICC

I claim as new, and desire to secure by Letters Patent, is

1. The combination with a window-frame having a guideway, of bars having ribs, a sash having grooved edges to receive the said ribs, and a pivotal connecting mechanism between the sash and the ribs consisting essentially of a sectional. pivot-pin whose sections are toothed to engage with each other and elastic means between said pin and the movable bar through which it passes.

2. The combination with a window-frame having a guideway, of bars having ribs, a

sash having grooved edges to receive said ribs,

and a pivot between the sash and movable bar, said pivot consisting of a tubular part attached to the sash and toothed at one end, a second part similarly toothedto engage the teeth of the first part, a securing-screw passing through both parts and entering the sash,

and a spring tensioned between the outer part and a recess in the movable bar, substantially as described.

3. The combination with a window-frame having a guideway, of a bar and a sash, and means for pivoting the two together consisting of a tubular sleeve attached to the sash and toothed at its outer end, a flanged tubular part similarly toothed to engage the teeth of the first part, a headed screw passing through both parts and being firmly screwed into the sash and a spring tensioned between the flange of the outer part and a recess in the movable bar,

4., The combination with a window-frame having a guideway, of a movable bar having a rib, a sash grooved on the edge to receive ARGHIBALD L. BOLLES.
