MEANS FOR POSITIVELY RETAINING WINDOWS IN OPEN OR CLOSED POSITIONS.

SPECIFICATION forming part of Letters Patent No. 792,817, dated June 20, 1905.

Application filed August 1, 1904- Serial No. 219,150.

To all whom it may concern:

Be it known that I, NEWTON R. EvANs, a citizen of the United States, residing in the city of Richmond, in the county of Wayne, and in the State of Indiana, have invented new and useful Improvements in Means for Positively Retaining Windows in an Open or Closed Position, of which the following is a full, clear, and exact specification and being such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is intended primarily to be employed in connection with horizontally-pivoted windows, and more particularly where such windows are elevated or are some distance above the floor, although the invention may be used upon other kinds of windows and may be used to operate doors or blinds with almost equal advantages.

The particular object I have in view is the provision of means for easily operating and for positively retaining horizontally-pivoted windows or the like in an open or closed position.

Another object is to provide means for positively retaining windows or the likein an open or closed position which will be simple, strong, and durable in construction, positive in action, neat and attractive in appearance, and which can be manufactured and sold at a comparatively low price.

A still further object is to provide a construction for the operation and retention of pivoted or hinged windows, transoms, or doors whereby the movements will be positive, yet practically noiseless, and to reduce to a minimum the liability of breakage or inadvertent displacement; and, finally, a still further object is to provide a self-contained and mechanically-complete mechanism which will by spring-pressure retain a swinging or pivoted window or the like in an open or closed position and .which will be easily actuated manually.

Other objects and specific advantages of my invention will be made manifest and will suggest themselves in the course of the ensuing specification.

The preferred constructional features I employ are visualized in the aceompanyingdrawings and are correlated in the claims hereunto appended.

Referring now to the drawings, Figure 1 is a vertical cross-sectional view of a window frame, the sash being closed and showing my invention in elevation and as applied thereto. Fig. 2 is a vertical cross-sectional view of a window-frame, the sash being tilted or open and showing my invention in elevation and as applied thereto. Fig. 3 is an inside face view in elevation of a portion of a window-frame and sash and my invention complete applied thereto. Fig. 4 is an enlarged detail longitudinal sectional view of the cylinder and connected parts, showing the constructional features of my invention; and Fig. 5 is a detail perspective view of the pivotal hanger for my invention.

Similar indices refer to and denote like parts throughout the several views of the drawings.

In order that my invention may be the more fully understood and comprehended, I will now take up a detail description thereof and will refer to the various parts as briefly and compactly as I may.

In the drawings the letter A denotes a window-sash pivotally mounted in a window-frame B, (only one side of which is shown,) the sash being of a size to neatly fit the aperture in the frame and is carried by a pair of pivots 1, (only one of which is shown,) which pivots project out from the sides of the sash into the opposing faces of the jambs, substantially as indicated in the drawings.

By the above it is apparent that the windowsash is pivotally mounted; and my invention consists more particularly in the means for operating and for retaining the sash in one or the other of the positions shown in Figs. 1 and 2', the essential portions of the invention being clearly shown in Fig. 4.

The numeral 2 designates the cylinder,which is closed at its lower end by the head 3, which head has aprotuberance 3 integral therewith, which extends down, with an aperture 3" therethrough to receive an axle, as the axle 10*. The opposite or upper end of the cylinder is to be closed by a screw-cap 4:, threaded exteriorl y to the cylinder, with amammiform protuberance 4 extending out centrally from and integral therewith and with an aperture extending centrally through said cap 4 and protuberance 4 to neatly receive the piston-rod 5 operatively therethrough.

The numeral 6 denotes a double-headed piston whose diameter is somewhat less than is the interior diameter of the cylinder, whose ength is considerably extenuated in an axial lirection with the two heads or end flanges 6 tnd 6 of a diameter to neatly lit the interior )f the cylinder, as shown, thus forming a spoolshaped piston adapted to glide interiorly of the cylinder. A threaded aperture extends centrally from the upper end down into the piston to receive the threaded end of the piston-rod 5.

The numeral 7 denotes a relatively long helical spring disposed within the cylinder 2, one end being seated against the head 3 and the other end being seated against the lower end of the piston 6, with its tension such as to normally retain the piston in the upper end of the cylinder, yet allowing it to be moved down against the torsional force of the spring 7 The numeral 8 denotes a relatively short helical spring disposed within the cylinder 2, one end being seated against the cap 4 and the other end being seated against the upper end of the piston 6, with its convolutions encircling a portion of the piston-rod 5, with its torsion such as to normally retain the piston somewhat below the upper end of the cylinder, yet allowing it to be moved up against the torsional force of the spring 8.

In this instance it is not intended that the cylinder 2 should be air-tight; but, rather, I have allowed for the free ingress and egress of the air through the apertures 00 and y, formed in the lower part of the cylinder 2 and in the cap 4, respectively, as indicated. However, in some instances I may prefer to close said apertures and to allow the air to enter and escape from the ends of the cylinder very slowly to allow the air to act with or in place of the springs or in connection therewith.

In Fig. 5 is shown the hanger, which consists of the plate 9, with the lug 9" extending up integrally from near one end of its face and then over its central portion, with an aperture formed through the free end portion of the lug 9, and coinciding therewith is an aperture in the central portion of the plate 9, which apertures are to tightly receive the axle 10, which axle projects at right angles to the plate 9 for some distance beyond the face of the lug 9, and an aperture 1O is formed through said axle near its free end to receive a spring-key 11. Screw-holes are formed through the plate 9, whereby it may be attached to another object, as a window-jamb, by screws.

The numeral 12 denotes a bracket with screw-holes in its feet, whereby it may be attached to another object, as a window-sash, by screws. The bracket 12 extends out convergingl y, with an aperture therethrough near its outer point to receive the pivot 5, formed on and turned at right angles to the outer end of the piston-rod 5. Near the free end of the pivot 5 is an aperture 5 therethrough to receive a spring-key 13.

The numeral 14 denotes a circular rubber gasket, round in cross-section, adapted to extend around on the periphery of the body of the piston 6, at the same time contacting with the inner wall of the cylinder and being adapted to roll on the piston between the two flanges thereof as the piston is moved up and down in the cylinder, the object thereof being to retard the too sudden movement of the piston and also to serve as a packing for the cylinder, if desired. However, the said gasket may be entirely dispensed with.

Secured near the upper end of the sash A is an eye-plate 15, in which may be secured the upper end of the cord 16, and secured to and near the lower end of the sash A is an eye-plate 17, in which may be secured the upper end of the cord 18. Secured to and near the edge of the surface of the window-sill is a hanger 19, carrying the revoluble spool 20, over which spool passes the cord 18, whereby said cord is prevented from drawing against the window-sill.

It will now be understood that the cylinder and its immediate connecting accompaniments are assembled, as in Fig. 4, the hanger shown in Fig. 5 being secured to the jamb of the window-frame, as shown in Figs. 1, 2, and 3. The cylinder is then pivotally secured to the said hanger by inserting the axle 10 through the aperture 3 and then inserting the key 11 in the aperture 10. The pivot 5 of the piston-rod 5 is now placed through the aperture therefor in the bracket 12, where it is pivotally secured by inserting the key 13 in the aperture 5", the eye -plates 15 and 17, the cords 16 and 18, and the spool 20, with its hanger 19, being relatively located and secured in the manner shown and as above indicated. It will now be seen that the window being closed, as in Fig. 1, the expansive torsion of the spring 7 is such as to retain the window-sash in its closed position; but now should the cord 16 be pulled down the force of the spring 7 will first be overcome, and on being further turned the spring will soon pass its maximum point of contraction, after which its torsion will be exerted expansively upon the window-sash, and thus accomplish the latter part of the movement of the sash to bring it to the position shown in Fig. 2, in which position it is held by the expansive torsional force of the spring 7.

To close the window-sash, the cord 18 is pulled, drawing over the spool 20, whereby the same movement and action of the cylinder and spring 7 is repeated as in opening the window.

It will be noticed that the spring 8 acts IIO simply as a butter to relievethe parts of sudden jars, which might be detrimental to the window and to the mechanism.

In this instance I have shown the sash A, pivoted horizontally somewhat above the center. However, it may be pivoted in the center or even below the center, if desired, and the sash may be pivoted or hinged at the top or even at the bottom, and with good results it may be pivoted or hinged vertically or at the sides to swing horizontally with equal or at least good results, it of course being understood that I make no claim to the construction of the window or its operation, and I even contemplate that my invention may be used for purposes other than windows.

From the above it will be seen that I have produced a construction which will accomplish the above-named objects in a practical manner, and while I have shown and described the best means known to me at this time for carrying out my invention I desire it to be understood that I do not restrict myself to the exact details of construction shown and described, but hold that any changes or variations therein as would suggest themselves to the ordinary mechanic would clearly fall within the limits and scope of my invention.

Having now fully shown and described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. Means for positively retaining windows in an open or closed position, the combination with a window-sash, of a bracket secured to the face of the sash, a hanger secured to the window jamb, a cylinder pivoted to said hanger, a piston operative in the cylinder, a piston-rod secured to the piston and extending out and pivotally mounted to said bracket, springs within the cylinder one being con- 4 nected with each end of the piston, and means independent of the above for opening and closing the window, all substantially as shown and described and for the purposes set forth.

2. In combination with awindow-frame and a sash pivoted or hinged therein, means for opening and closing the sash manually at a distance therefrom, a cylinder pivoted at one end to the window-frame, a spool-shaped piston operative in said cylinder, a piston-rod 5 extending from the piston through and beyond the upper end of the cylinder, a bracket secured to the sash, means for pivoting the upper end of the piston-rod to said bracket, a helical spring disposed in the cylinder be tween the piston and the lower end of the cylinder, and a similar but shorter spring disposed between the piston and the upper end of the cylinder, and means for retarding the action of the piston by a gasket surrounding the piston, all substantially as shown and described and for the purposes set forth.

In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
