This-invention relateswas indicated to springs, but :has reference :more particularly to: a spring of the leaf type which is especially adapted for controlling the movements of windows and the like.
Aiprimaryobject o'f theinvention is to provide a spring of the character described, which is extremelyweffieient in use; and :highly 'efiec'tive fcr thepurpose iforiwhich itlias been-designed.
Another robjectotithe invention is to provid'ei'a spring of thecharacte'r *described, whichis made 1' fromza single: piece of. sheet or-stripfiinetal, by simple and economical manufacturing operations, and, which can :be sold at an extremely low price and quickly and easily installed without the use of: tools. other. than ordinary hand tools, such as a hammer.
A further object rofvthe invention is to provide a spring iofiithe character described, which can be used as an item of builders hardware, for installation in both old and new buildings.
A still further object of the invention is to provide a spring of the character described, which can be easily. and .quickly adjustedto vary the tension thereof.
Other l'objects and advantages of the invention will be apparent during the hoarse-er the following description.

Fig. 10 is a fragmentary perspective view, illustrating the use of the spring in an upper Window channel, and
Fig. 11 is a fragmentary perspective view illustrating the attachment of the spring to the edge of a window sash.
Referring more particularly to Figs, 1 to 8 inelusive, of the'rdrawingadt twill be-seen that the control; spring comptises a fiatnthin metalplate ;I having ends roundedl-as at ig-and provided at it 1 d with ,;:perf;orations .;or 1110135 .6, through which tacks or nailsmay-be inserted for the .pur pose. of securing the ,lplate in place, .as:- will be presently 1 explained.
The plate I 'is stamped to provide tongues rd andfi, which are 'identicalin' every respect, the tongue 4 extending longitudinally from one end of the .plate, and the tongue 5 extending longitudinally from ,the opposite rend of the plate, andin aidirection opposite to that of the tongue 4. The tongue 4 ,is connecte d to the plate I- as at 6, and the tonguei connected to the plate I as at I.
.i lhe. tongue 4 is stamped outwardly to provide aportion 8 which extends at aslight'angle to the plane of the plate an intermediate flat portion 9, which lies in a plane substantially parallel with the plate and ,anend portion I0, which also extends at asligh't angle .to the plane of the plate land which terminates substantiallyin the plane of the plate I. Q'Siniilarly, the tongue 51s stamped outwardlyto .provide apor'tion I I which extends a.slightjangleiztofthe plane of the plate -I, an intermediate, fiat portion PI? which lies in a plane substantially, parallel with the plat 1 and. an en 'pcrtidnl'3 i h ais ie itend's at. a slig ht jan'gle'to. the planets thejplate ll and which eterininates substantially jthe .plane of the plate @I.
It 'willbe furtherl-iidtedfjthat the ,portion 8 or the tongue djincrfea'ssiin width as the point 6 of its connection with e plate TIjis approached, and that this widenedipor "on overhangs @to some extent the end T3 of the tongue 5. Similarly, the portion I I of the tongue 5 increases in width as the point I of its connection wtih the plate I is approached, and this widened portion overhangs to some extent the end II] of the tongue 4. Moreover, the portions 9 and I2 of the tongues: 4 and 5 respectively lie in substantially the same plane, and are substantially parallel with each other. By this construction and arrangement of the tongues 4 and 5, space is conserved, so that the spring can be made from as small a piece of metal as possible, and, at the same time, the areas of connection of the tongues with the plate I are made as long as possible, so as to decrease the likelihood of the tongues breaking off from the plate as the result of repeated fiexures of the tongues relatively to the plate.
The tongues 4 and 5 constitute springs which are especially adapted for controlling or regulating the movements of windows in their channels, acting to take up any looseness between the windows and the channels, and also acting to maintain the windows in adjusted position. Its use eliminates the use of sash cords, weights and pulleys.
In using the control springs in lower window channels, both windows are left in a closed position. One of the springs is then inserted between the window sash and the window channel, as shown in Fig. 9. The spring is then tapped downwardly, so that approximately the lower third of the spring extends below the plane of the upper rail of the window sash, and the upper end of the spring is then tacked in place. Another spring is then similarly positioned at the opposite side of the window. Upon raising of the lower window to its full extent, the lower ends of the springs will be exposed, and can be tacked or nailed to the window channels.
The spring tongues act to take up any loose play between the lower window and its channels, and thus serve to control or regulate the movements of the window, the window remaining in any desired position of adjustment. If the window is exceptionally loose, the tension of the springs may be adjusted'by bending the tongues in a suitable manner. In the case'of abnormally loose windows, a plurality of springs may be employed.
In using the control springs in upper Window channels, the lower sash is raised to its highest point. One of the springs is then inserted between the window sash and the window channel, as shown in Fig. 10, and is tacked or nailed in place. Another spring is then similarly positioned at the opposite side of the window. Upon lowering the window sash to its full extent, the upper ends of the springs will be exposed, and can be tacked or nailed to the window channel.
In new buildings, before installation of the windows, the springs may be secured directly to each side of the upper sash, at a point about 6 inches below the top rail, as shown in Fig. 11. The springs may then be compressed, in order to set the sash in place. For the lower window, the same procedure is followed, the springs being placed on each edge of the sash about 6 inches from the top. The spring tension of the springs against the window channels will thus permit both windows to remain in any desired position. If the windows fit too tightly or too loosely, the tension of the springs can be adjusted by sultably bending the tongues thereof.
It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims.
I claim:
1. A spring for controlling the movements of windows, said spring comprising a metal plate having parallel transversely spaced tongues extending longitudinally from opposite ends of said plate, all portions of said plate, except for said tongues, lying in substantially a common flat plane, each tongue consisting of a plurality of angularly related portions, and each tongue being connected to the plate by a portion which increases in width as it approaches the plate.
2. A spring, as defined in claim 1, in which each tongue has a central fiat portion which lies in a plane parallel with but spaced from the plane of the plate and in which the central fiat portions of both tongues lie in substantially a common flat plane.
3. A spring, as defined in claim 2, in which each tongue has an end poition which extends angularly to the plate.
4. A spring, as defined in claim 3, in which one of the end portions of each tongue is connected to the plate and the other end portion of each tongue is unconnectedto the plate.
5. A spring, as defined in claim 4, in which the end portion of each tongue which is connected to the plate overhangs the unconnected end portion of the other tongue.
6. A spring, as defined in claim 5, in which said plate has apertures in the ends thereof, adapted to receive fastening means.
