's'ronM-sAsn HOLDER.

Application filed March 17, 1927. 7 Serial No. 176,003. 7 i

This invention relates to holding devices for swinging sash and especially to storm.

portion of the window frame, whereby said swinginv sash may be readily attached and said'hol erproperly secured to said bracket for operation without installation of parts.

Another object is to provide in a storm. sash holder, means to prevent the storm sash from rattling at its point or points of connection with the holder proper.

These and other objects -of the invention will be apparent from the following descrip tion made in connection with the accompanying drawings, in which like reference characters refer to similar parts throughout the several views and in which Fig. 1 is a vertical cross section through a lower portion of a storm sash and window frame showing a preferred embodiment of my device attachedthereto in operative posi-' tion, anintermediate position of said storm sash being shown in dotted lines;

Fig. 2 is a similar View showingsaid storm sash in closed position; Fig. 3 is a vertical section taken on the line a-s of Fig. 2; v

Fig. 4 is a perspective view of the attaching1 bracket employed on the window frame; an

Fig. 5 is a perspective view ofa substantial portion of the inner arm employed in my holder.

In the drawings, the sill of the window frame is indicated by the numeral 6 and the vertical sides of said window frame by the numeral 7. The usual spaced sash stops 8 are provided on the vertical sides 7 between which the upper sash of the window is guided. A swinging sash, illustrated in the drawings, as a storm sash is pivoted to the upper portion ofv a window frame (not 1 shown) and its lower horizontal rail or frame member is indicated by the numeral 9;

My sash holder when the swinging sash is detached is carried thereby and may be secured thereto by means of abracket 10 having a vertical flange disposed at right angles to the surface of rail 9. An outer arm 11, of preferably fiat material is pivoted at its outer end to said flange or bracket 10 andhas a,

lower longitudinally recessed portion 11 formed at its lower longitudinal edge affording a small bell crank lever arm 12 in connection with the of toggle arms and is pivoted at 14 to the other arm 15 of said pair. Arm 15 may be of substantially rectangular shape having a key hole slot 15 formed adjacent its inner end, which slot is adapted to receive the head 16 of a pivot member projecting longitudinally and substantially horizontally from the end of an angle bracket 17. Angle bracket 17 is'preferably secured to a vertical wall 7 of the window frame between the sash stops 8,. said pivot or lug extending towards the op posite side of said window frame.

Arm 15 is pivotally attached to bracket 17 by insertingthe head 16 of said pivot into the key hole slot 15, slipping arm 15inwardly slightly and swinging a retaining arm 1.8 downwardly to permit the pivot'16 to be engaged by an arcuate slotted portion l8 'adjacent the free end of arm, 18. This,

obviously, prevents the headed portion 16 of said pivot from slipping out of said key hole slot. Arm 18 is pivoted intermediately of arm 15 on a threaded bolt 19 provided with a winged clamping nut 20. It will be noticed that the unthreaded end of bolt 19 extends through arm "15 and forms a lug 19*,best shown in Fig. 3, which is adapted to lock with a detent 21 formed in the'lower edge of arm 11 adjacent its inner end. Thus, when the storm sash is in fully open position, toggle arms 11 and 15 willbe substantially alined and detent 21 will be engaged by said'lug 19 Theoperation of the above described device may be briefly summarized as follows: When the storm sash 1S closed the several pivot 13 securing said arm to said flange. Arm 11 forms one of a pair elements will be positioned, as shown in Figs.

2 and '3, the lower edge or rail 9 beingengaged by the sill 6 and toggle arms 11 and 15 being positioned in nearly coincident relationship. The elongated recessed portion 11 of toggle arm 11 accommodates the projecting arms 19 disposed intermediately of the ends of toggle link 15 when the storm sash is in closed position. Sufficient friction is afforded between the contacting surfaces of arms 11 and 15 to prevent the storm sash from swinging outwardly. To fully open the storm sash it is only necessary to apply pressure against the inner side thereof causing tog le arms 11 and 15 to be swung apart and disposed in alinement, as shown in Fig. 1, detent 21 fastening with lug 19 and positively preventing said arms from displacement by wind. It will. also be noticed that as the arms are swung apart the bell crank arm 12 formed at the outer end of arm 11 will be cammed or forced against the base of bracket 10 thereby taking up any looseness between the pivot 13 and arm 11 and preventing rattling of said storm sash.

The storm sash may be held in various positions intermediate of said closed position and said open position by the friction between arms 11 and 15 and in Fig. 1 the dotted lines indicate said storm sash held in intermediate position.

It will be seen that in detaching the storm sash from the window frame it is only necessary to loosen wing nut 20, swing arm 18 upwardly and remove pivot 16 from key hole slot 15. The toggle arms, bracket 10 and all elements of the sash holder with the exception of bracket 17, are carried by the storm sash and are removed with said sash. Bracket 17, of course, does not interfere with the sashes in the window frame, sinceit is preferably disposed between the stops 8 for the upper sash and since there is no occasion for lowering the upper sash of the window'to such extent that the lower edge thereof will abut bracket 17.

In many forms of storm sash holders on the market the holding arm or arms, until they are extended with the storm sash in open position, project in the line of the lower window sash and consequently the lower sash must be raised a considerable distance before opening the storm sash. Such devices often interfere with furniture adjacent the inside of the window andmoreover cause considerable trouble to manipulate. lVith my device the toggle arms extend at all times between the storm sash and-the bracket preferably located in the space between the upper sash stops. The lower sash never needs to be opened widely to manipulate my device. As has been stated, it is only necessary to push the storm sash outwardly, causing the toggle arms to be extended.

It will be seen from the foregoingdescription that I have invented an extremely simple,

durable and highly efficient holder for swinging sashes adapted to hold said swinging sashes positively fastened in open position and adapted to securely hold said sash in closed and various intermediate positions be tween closed and open position. It also has been seen that due to the camming action of the bell crank arm 12 the connection between the outer toggle arm 11 and the swinging sash, the sash will not rattle as is often the case in sash holders.

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