STORM SASH HOLDER Filed Jan. 27, 1930 Patented Aug. 25, 1931 GEORGE-A. AWALT', OF MINNEAPOLIS, MINNESOTA STORM SASI-I HOLDER Application filed January 27, 1930. Serial No. 423,692.

This invention relates to storm sash holders or retainers and has for one of its main objects to provide a simple but highly efticient storm sash holder', which may be manufactured at low cost and which will secure the storm sash in various open positions and lock the sash in closed position.

It is another object of my invention to provide a storm sash holder or latch, wherein the sash may be secured in any desired open position within certain limits by means of a simple eccentric mechanism which cooperates with one or more of the links or other members connecting the storm sash l5 and the window frame. j

Still a further object is to provide a holder for storm sash comprising a pair of links pivoted to an attachment bracket which may be secured to the storm sash or the window frame, the said links diverging from the bracket and having at their outer ends slidable connections with suitable guides secured to the window frame or storm sash as the case may be, said links working in cooperation with simple locking or retaining mechanism which is adapted to engage the pivoted ends of the links to hold 'the storm sash in any desired open position within certain limits.

0 These and other objects and advantages of the invention will be apparent from the following description made in connection with the accompanying drawings, wherein like reference characters refer to similar 5 parts throughout the several views, and wherein; Fig. l is a horizontal cross section taken through a window frame having the usual lower sash and swinging storm sash mounted thereon and having an embodiment of my invention applied to the window sill and storm sash, the storm sash being shown in closed position and an open position of the storm sash and my retaining device being shown in dotted lines; Y

sash X.

The embodiment of my invention illusg trated includes a suitable attachment bracket 7, which, as shown, comprises a short angle strip adapted to be readily attached to or detached from the inner face of the storm sash adjacent the lower edge thereof; Adjacent its lower edge, the storm sash X is' preferably provided with a pair of screws. or bolts 8 having their heads spaced a short distance from the face of the storm sash and the vertical arm of bracket 7 is provided with a pair of spaced locking apertures 7a having enlarged lower portions for reception of the heads of screws 8 and relatively narrow upwardly extending confining slots 7b communicating with said apertures.'v A small aperture 71o may be formed in the horizontal arm of lthe bracket 7 and the lower, and reduced end of an upwardly projecting pivot post 9 is extended through aperture 7c and riveted or otherwise secured to the horizontal arm of bracket 7.

Aai

As shown, bracket 7 is adjustably connected with the sill of the window frame by means of a pair of links 10, said links having terminal eyes 10a, which surround pivot post 9, one disposed above the other for a purpose later to be described. The two links 10 diverge from pivot 9 toward the sill S. If desired, links 10 may be constructed from metal rods,'and the eyes 10a flattened to increase the frictional area between the portions of the links lapped on pivot 9.

The divergiiig ends of links 10 are provided with offset extremities 10b which underlie and slide in a pair of elongated slotted portions 11a formed in an elongated attachment bracket 11, preferably constructed in the forni of a strip. Attachment strip 11, as shown, is secured to the window sill, spaced some distance from the outerV edge thereof and is provided with offset attachment flanges 11b at the ends thereof adapted to engage the sill and a central depressed attachment flange 110 also adapted to engage the sill, suitable means, such as screws 12 securing said several attachment flanges to the upper surface of the sill. The slotted portions 11a of strip 11, as clearly shown in Fig. 5, arespaced a short distance above the sill in order that the offset endsof links 10b may be lnicely accommodated therebelow. An upstanding locking flange 11d is provided at the central attachment portion of the strip for a purpose later to be described.

f To securely hold the storm sash in a desired open position I provide simple but efficient mechanism mounted on the attachment bracket 7 and preferably carried by upright post 9. As illustrated, a A.coiled spring or other elastic or compressible member 15 surrounds the lower portion of pivot post 9 beneath the eyes 10a of the links. The

Vupper portion of pivot post 9 is preferably slotted longitudinally from the upper end to a point some distance below the upper surface of the upper eye 10a. An eccentric 13 is accommodated in the slot of post 9 and is pivoted to the forked upper portion of the post on a pin 14, which preferably extends at right angles to the aXis of post A 9. The working edge of eccentric 13 is adapted to engage the upper surface ofthe uppermost eye of the links 10 and I prefer to shape the working edge of the eccentric in such manner that it will be moved to a dead center position by less than a O turn thereof. The spring 15 is of such length and expansibility that it will yieldingly hold the two eyes 10a of the links against the edge of the eccentric with a considerable degree of friction.

Eccentric 13 is provided with a handle 13a extended in the direction of the sash Y and terminating in a downtu'rned hook The operation of my storm sash holder may be briefly described as follows With the eccentric handle 13ay in raised k position, the storm sash may be swung outwardly to a desired open position within the limits provided, according to the length of links 10. Coil spring 15 causes the overlapping eyes of the links 10 to be yieldingvly and frictionally held against the edge of the eccentric. In many instances, this frictional engagement of the eyes of the links is sufficient to hold the storm sash in open position. However, to positively retain the same, eccentric arm 13a may be swung downwardly causing the working edge of the eccentric to tightly clamp the lapped eyes 10a of the links against the top of the compressed spring 15. The slight yielding action of the spring 15 in cooperation with the eccentric affords a slightly better friction clamping device than if the spring were eliminated, although, of course, I contemplate the use of the eccentric device with the overlapping eyes of the links without the interposition of the yieldable element or spring, all within the scope of my invention.

During the outward swinging movement of stormsash X, the divergiiig ends ofthe links will, of course, slide inwardly guided by the slotted portions 11a of the sill bracket and will be limited in inward movement by the inner ends of the slots. ends of said vslots are spaced a sufficient distance apart so that links 10 wheny the storm sash is in full open position, will always diverge sufficiently to permit easy sliding of their offset ends 10b when the Vstorm sash is swunginwardly.

The handle 13a and hook 13b of the eccentric may be grasped and utilized as an operator for closing or opening the storm sash and when the storm sash is positioned against the blind stop B the handle lamaly then be swung downwardly, the eccentric frictionally clamping the lapped ends of the links and the hook 13b having positive locking engagement at that time with the upstanding locking` flange 11d of the sill attachment strip.

It will be seen that the attachment bracket 7 may be quickly removed from the storm sash by sliding the same upwardly to position the heads of screws 8 inthe Venlarged portions 7a of t-he attachment arm of the bracket. lVhen the bracket 7 carrying the eccentric and pivot 9 is removed from the storm sash, the links may be Iswung or posi- The inner tioned to permit detachment of their olifset ends 10b from the guides or slotted portions of the attachment strip ll.

IVhile I have shown the bracket 7 and pivoted ends ot' the links attached to the storm sash it is, of course, quite obvious that my device may be reversed, the bracket 7 being attached to the sill at the proper point thereof and the attachment strip 1l secured to the storm sash, all within the scope of my invention.

From the foregoing description, it will be seen that I have provided a simple, highly eilicient and comparatively inexpensive storm sash holder, which may be secured by the cooperation of the links, eccentric and other working parts of my device to positively hold the storm sash in any desired open position within the limits provided. The device, `in addition, provides convenient operating mechanism by which the storm sash may be swung inwardly or outwardly and also effects the positive locking of the storm sash in closed position by the engagement of the hook 13b with the locking iiangey 11d.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts Without departing' from the scope of applicants invention.
