DEVICE FOR OPERATING WINDOWS OR SHUTTERS.

SPECIFICATION forming part of Letters Patent No. 740,953, dated October 6, 1903- Application filed February 21, 1903. Serial No. 144,458. (No model.)

Be itknown that I, EZEKIEL VAN Noonnnu, a citizen of the United States, residing at Boston, in the county of Suifolk and State of Massachusetts, have invented a new and useful Improvement in Devices for Operating Windows or Shutters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

My invention relates to an improved device for obtaining the simultaneous closure or opening of a series of swinging sashes or shutters and for holding the same closed or at any variable degree of opening.

My invention consists in certain details of construction the adaptability of which to the purpose for which they were designed can best be seen and understood by reference to the drawings, wherein- Figure 1 shows my device in elevation as applied for operating two adjacent sashes or where the sashes are arranged in series. Fig. 2 shows in elevation my device as applied for the operation of a single sash. Fig. 3 shows in cross vertical section the device applied to a window with the sash therein closed. Fig. 4 shows the same with the sash open. Fig. 5 shows a longitudinal cross-section of a certain detail of the construction, to which ref erence will hereinafter be made. Fig. 6 shows in cross-section a certain detail of construction, to which reference will hereinafter be made.

Referring to the drawings, A represents a frame in which there are arranged a series of sashes A and between the jamb portions of which, as from an axial center a, the sashes are pivoted to swing horizontally. Extending inward from'the respective sashes and thereto above andbelow the pivotal center of its support are the brackets B. These brackets are made alike, and they are secured to the side rails of the respective sashes to extend in uniform order, so as to be in line with one another, with which order of arrangement the brackets upon the adjoining side rails of the adjacent sashes are arranged in pairs, as may be seen inFig. 1. Each pair of brackets is united by means of a connecting plate or bar 11, preferably secured across their outer faces, and through the medium of which connecting-bar and brackets the adjacent sashes can simultaneously be moved or swung.

Pivotally secured to the leaf of a hinge b, which hinge is attached to each one of the cross-bars b, are the links 19 b YVith this method of jointure the said links are capable of being spread apart longitudinally from the center of their pivotal attachment to the hinge b or turned horizontally by reason of their connection therewith. The links b b diverge, and at the lower ends they are pivotally secured .to the sides of the longitudinal bars 19 19 respectively. These longitudinal bars 12 b are subjected to considerable strain, as will hereinafter appear when the way in which they operate is'considered. Accordingly they are made of angle-iron and are disposed alongside one another to have the relative order of arrangement shown in Fig. 6 or with the united bars forming a rectangular structure. By making the separate bars of angle-iron they are made strong and rigid and are not easily twisted or bent. By arranging the bars as shown they reinforce one another. The arrangement also facilitates the bars sliding by one another longitudinally in reverse directions, which movement the bars have, as will hereinafter appear. This formation and arrangement of thelongitudinal bars, however, is a more detail of construction; but it is good by reason of its practicability. Y

Pivoted to the respective bars I) b are the links b b ,which links are pivoted,preferably,

by the same pivoted jointure as secures the I links 6 11 before referred to, whereby the links b b b b become practically pivotally joined together in pairs. The links b 17 converge and at their lower ends are pivoted to the leaf of the hinge b which hinge is fixed to the frame, wherefore by such jointure the links b b may pivot longitudinally or turn horizontally, and for that matter the whole linked structure, if such be necessary for its proper operation. Of course there may be as many sets of links pivoted to the bars b b and pivotally hinged, as before explained, as is necessary, the number of course depending upon the number of sashes or shutters to be operated.

. Pivoted to the ends of the respective bars 12 b are the links b 17"". These links converge and at their lower ends are pivoted to one leaf of a hinge 12 which is secured to the frame, so that the links b b may turn horizontally.

Pivotally secured to the sides of the links 12 b respectively, are the threaded boxes or nuts 12 b through which extends longitudinally the right-and-left screw 1). The screw o by reason of its variable combined horizontal and vertical movement is guided by a cam-surface 17 of a bracket Z7 which is.

secured to the frame. By reason'of its variable motion also the screw 12 is turned by the universal-coupling connection Z2 which connects, through suitable bearings, with a pulley Z7 or any other suitable means of turning.

The operation of the various parts referred to is as follows: Assuming the sash to be closed, the parts have the relative order of arrangement shown in Figs. 1 and 3. Upon turning the right-and-left screw 17 the links b N, carried by the traveling nuts, are rapidly run apart. This mot-ion of the links is imparted to the bars 19 b and they in turn are moved in a longitudinal direction reverse to one another, carrying with them the links 1) 17 which have pivotal attachment with these respective bars, as before explained. The truss structure formed by the links is accordingly longitudinally extended at both sides, and consequently its vertical extension is relatively shortened; but the lower end of the linked structure, by reason of the links 6 b being fixed with the frame through their hinged connection I), is incapable of a vertical movement. The objective result is therefore necessarily obtained that the sashes must be turned by the downward draft of the linked structure upon the brackets B, to which the structure is secured by the ends of the links I) b and through the medium of the hinges b and connecting cross-bars b. As the sashes pivot, of course the brackets B, fixed to them, are caused to move longitudinally to describe an are, so that the truss structure, like as I have described, which is connected with these fixed brackets, or rather to their connectingbars I), must likewise have some degree of horizontal turning, which is attainable by the hingedjointure of the links 19 b and links b b to the said cross-bars and the frame, respectively, and it is to be observed in this connection that the truss structure, comprising the longitudinal bars and links through the point where it makes its hinged jointure with the frame, has a most variable movement in its operation, consisting of a longitudinal movement incident to the primary movement of the longitudinal bars and the simultaneous vertical and horizontal movement consequent upon the turning of the sashes, all of which movements are attainable by the methods of jointure before described. The right-andleft screw b, by which the reverse movement of the longitudinal bars is obtained, remains during its operation in relatively one position against a longitudinal movement; but ithas a vertical movement following upon the divergence of the links 11 b Of course the relative position of the screw b and the links 19 17 becomes changed by their divergence, and this is provided for by the traveling nuts, which compensate for such relative change of position and provide a free running of the screw whatever the position of the links may be. The screw, together with the links, turns also horizontally with the main structure before referred to, which movement is permissible by the hinged jointure of the saidlinkstotheframe. Thescrewb isguided in its combined vertical and horizontal movement by the cam-surface Z1 of the bracket 5 as before explained. The adaptability of the universal coupling to the variable motion of the screw is apparent.

In Fig. 2 a change of feature is shown in the fact that instead of simultaneously operating adjacent sashes the device is applied for the operation of individual sashes. There is no essential variation in the construction, onlyinstead of attaching the linked structure to the cross-bars connecting the brackets extending from the adjacent sashes they are directly secured to the brackets themselves, which are secured to the sash sides, as before explained. In point of fact,it makes no difference respecting the essence of my invention how many brackets there are or how they may be arranged, provided that all the sashes may be simultaneously closed by a means substantially like as I have devised; but the method referred to by which adjacent sashes can be simultaneously closed is perhaps the most practicable, especially if there are a series of windows.

My device is very simple. It is made up of parts which can be easily obtained and which do not require a special construction. It can easily be applied to any windows without changing their structure in any way.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1.
