0 rattle and which will prevent the sash from rattling or becoming displaced when open or partially open and which will not interfere in any way with the operation of the upper and lower sashes of the window.

Another object is to provide a sash holder of the type above described, which includes highly efficient frictional means associated with a pair of pivoted links, whereby the storm sash may be adjusted to a desired open position by merely swinging the lower edge thereof outwardly or inwardly as the case may be, the frictional elements securely holding the sash against rattling and displacement.

Still another object is to provide a compact sash holder which may be easily and conveniently attachedto conventional storm sash and window frames now extensively used and which is provided with a highly i efficient attachment bracket secured upon the 0 the invention will'be fully set forth in the following description made in connection with the accompanying drawings wherein like reference characters refer to similar parts throughout the several views and wherein, Y

In the drawings, aaconventionaltype yof window-frame is shownhaving a sill S, the

The lowthe storni sash may be swung to open or vclosed position. y My sash holders eachcom- .prise a pair of kpivoted links associated withy the stormlsash andthe window frame (usually the blind stop of Vthewindow frame) for adjustably holding the storm sash 'in a desired open position and .for'permitting the sash to be entirely closed .flush against the are used for each installation aiidsince the devices are identical, for .the purpose of brevity, only one thereof 4will be described.

The said device comprises ya pair` of flat mon in most types of-vwiiidfow frames. The

ler member or railof the storm sash Xis .L provided with a suitable handle H by which vblind stop. ,Ordinarily two of these` devices i links 10 andrllrespectively, pivoted togetlier by suitable means', suchas a rivet .12, adjacent their. :inner ends. `The `outer link l0 projects atits inner extremitysome distance beyond the pivot 12 carries a resilder tension by the rivet 12 nwhich extends nient clip4 13 bowed slightlyandclampedun- 1'# through the approximate center thereof.

`Clip 13 may be constructed of suitable resilient material and is provided at each of its ends and along its longitudinal edges with inturned projections forming two pairs of straddling members for engaging the longitudinal edges of link 10 adjacent the pivot to prevent oscillation of the clip upon the link. Three of said inturned projections are numbered 13a and terminate inwardly of or at least flush with the inner surface of link 10. The upper projection numbered 13b adjacent the extremity of link 10 is projected beyond the longitudinal edge of link 10 in order to engage and abutY the longitudinal edge of link 11 when the links are swung outwardly into longitudinal alinement. This positively holds the links extended in a straight line with the storm sash opened to its full limits with my device applied. The link 10 at its outer end is pivoted by suitable means, such as a rivet 14, with the out-turned ear of a small angle bracket 15 having an attachment base which is secured by suitable means, to a point at one side and adjacent the lower rail of the storm sash X. The link 11 is detachably pivoted to a small and compact bracket 16 which is secured to the window frame and preferably to the side of the blind stop B. Bracket 16 comprises a vertically disposed plate having adjacent the upper portion thereof a short projecting stud or pin 16a which is adapted to receive the end of link 11 passing through an aperture 11a formed in said end, and a retaining lever 17 is pivoted by a rivet 18 to bracket 16 at a point below pin 16a, said lever having a relatively short and slightly Y offset end 17a which is adapted to engage and slide over the outer end of pin 16a and the outer surface of the connected end of the link 11, preventing displacement of the link from the bracket while permitting pivotal movement of the link 11 upon the pivot pin. The handle end 17 b is elongated to permit the lever to be easily manipulated for attaching or detaching my storm sash holder from the window frame.

When the storm sash is fully closed against the blind stop B, the links 10 and 11 will be swung together and superimposed in the positionshown by the dot-ted lines in Fig. 1, and to assist in holding the links in superimposed position, and thereby prevent accidental opening of the storm sash, I may provide a small projection 11b on one of the links adapted to register and interlock with va detent 10a formed in the appropriate surface of the other link, when the links are 'swung together in fully closed position.

The links 10 and 11 are preferably formed of metal or material having some resiliency and the links may be swung apart by apply- 'ing slight force.

The clip 13 in addition to limiting the outward swinging movement of the links and holding the links in longitudinal alinement also yieldingly forces the pivoted ends of the links into frictional engagement, since the resilient clip is under considerable tension supplied by the rivet 12. The flat opposed surfaces of links 10 and 11 adjacent the common pivot afford considerable frictional area and the structure with the clip is so efficient that the storm sash may be held frictionally in any open position between closed position and the fully open position illustrated in the drawings, without the addition of other clamping or locking means. To open or' close the storm sash, assuming the links 10 and 11 to be out of longitudinal lalinement, it is only necessary to grasp the handle H and swing the storm sash to the wardly.

In connecting or disconnecting the inner link 11 with the bracket 16, retaining lever 17 is swung slightly out of vertical position `whereupon the apertured end of link 11 may be engaged with or disengaged from the pivot stud 16a. It will be seen that with this readily detachable connection, the storm window may be readily installed upon or detached from the window frames.

Vhen the storm windows are detached, the links 10 and 11 are folded upon each other and swung compactly against the frame of the sash Whereafter the storm windows may be stacked or piled conveniently.

It will be seen that with my device, no part of the links or other elements ever project inwardly in the path of the upper and lower sashes of the window.

From the foregoing description, it will be see that I have invented an extremely sim ple and improved storm sash holder, which may be manufactured at very low cost, which will be effective to hold a .storm sash in a variety of diiferent open positions and by which the storm sash may be adjusted without releasing hooks, clamping devices or other means. The frictional conection between the links, connections of the links with the attachment brackets, as well as the fact that the links are relatively short prevent the devices and the storm window from rattling or working loose.

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 my invention, which, generally stated, consists in adevice capable of carrying out the objects above set forth, in the novel parts and combinations of-parts disclosed and dened in the appended claims.
