1 Claim; .(Cl. 292-263) Myinvention resides in a devicedesigned for blind stop, underlying the anchor plate, and use as a-storm sash holder, and embodies in registering with the slot 16 and the circular its construction means for supporting the storm recess 17 therein.

The lock washer permits a window a ly f y pp v construothe toggle members to pivot on the bolt 26 with t in Which the p face Plate is indicated a yielding frictional contact. The head of the by e numeral 9, and t blind p by the bolt 26 is elongated so as to constitute a crank numeral 11. The storm sash 12 has a hooked, h ndle, by means of which thetoggle may be ropivotal eehheetieh; as at between its upper tated about the aligned pivotal points 22 and cross ra nd the plate 0, When in its 25, when the storm sash is in its closed position.

In the drawing, I have lind t p a anchor plate 14 is permanently shown a blade spring 28, attached at one end to a at ach by means of screws 5, passed through the toggle member 24, and provided at its free r perforations in the anchor plate, and entered end with a perforation through which the stud into t e blind p- The anchor plate 14 is 25 is passed; but any type of spring may be used slotted laterally from its inner edge, as at 16, for the purpose, I and is counterbored at the end of the slot, to With the storm sash supported upon the hooks provide acircular recess 17 on its inner side, 13, the shankof the stud 25 may be passed into ior a purpose which later will be described. 'A the slot 16 by compressing the spring 28 againstchannel 18, is cut partly across the face of the the anchor plate, and the head of the stud entered in the circular recess 17. The spring 28 then acts to prevent accidental disengagement of the head of the stud from the recess.

The toggle member 24 is provided at its inner end with an offset finger 29, which overlies the corresponding inner end of the member 23, which finger serves as a stop to maintain the toggle in its open position, as in Fig. 2, and prevent downward deflection. A like finger 30 is provided upon the outer end of the toggle member 24, and is adapted to extend over the corresponding outer end of the toggle member 23. In closing the storm sash, the toggle members are caused to extend upwardly as in Fig. 1, and when the storm sash is completely closed, the pivotal points 22 and 25 are in axial alignment, as before stated. The toggle may then be rotated as a whole by means of the projecting end of the bolt 26, and brought into the lower position indicated in Figs. 3 and l, at which time, the finger 30 will lie to the outer side of the toggle member 23, so that the storm sash cannot be opened until after the toggle has been reversely rotated to its upstanding position. This arrangement prevents the storm sash from being opened from the outside, and securely holds it against rattling.

' A stay bar 31 pivoted at one end to the toggle member 23, is provided upon its under edge with one or more notches in the region of its free end, any one of which notches is adapted to take over the finger 30, when the storm sash is opened, and to so maintain the storm sash in a fixed opened position. The stay bar 31 is adapted to be folded into parallelism between. the toggle members, when the toggle is folded, as indicated in Fig. 4, when the storm sash is closed. A stop 32, projecting over the pivoted end of the stay bar, serves to restrain the said bar from falling below its operative plane, as shown in Fig. 1. The free end of the stay bar 31 projects beyond the stop 11 and into the channel in which the upper sash of the window moves. By lowering this said upper sash until its bottom rail rests upon the inwardly projecting end of the stay bar 31, the storm sash will be held securely in its partially opened position, thus affording excellent ventilation over the lowered upper sash, and effectively excluding rain, snow, or direct blasts of air. If the said upper sash be secured in its ventilating position, as described, the storm sash cannot be moved from the outside, with the result that entry through the window is prevented. This is a desirable assurance whenthe rooms are used at night for sleeping purposes.

When a change of season renders the continued use of the storm sash unnecessary, the latter may be detached by simply disengaging the studs 25 from the anchor plate 14., and unhooking at the connection 13. The storm sash may then be stored, and again be as easily replaced in position, when the cold season approaches.

Having thus described my invention, what I claim and desire to secure by Letters Patents of the United States, is:

A storm sash lock and regulator comprising a pair of links connected to form a toggle, pivot members for connecting the opposite ends of said toggle to a storm sash and window frame respectively, said toggle being swingable about the axes of said members into and out of locking position when the storm sash is in closed position, an element on one of said links for coaction with said other link to secure said sash in closed 1 position when said toggle is swung into said locking position, and a stay bar on said other link for coaction with said element to retain the sash in a predetermined open position.

JOHN CHRISTIAN.
