This invention-. -relates to :new and use'fulgimprovements in auxiliary windows. It risapahrtioularly concerned with an auxiliary "window sash of a type the organization and arrangement of which enables its use on the inner-or roomside of a window fi'amezotabuilding.

The invention :finds particular use with pi'cture window structures, such as are commonly :associated with ranch type and bungalow homes,

though it may well-he used with other type window structures. The picture window generally includes a large lower :area which is fixed and does not open. l'i'bOVE lihiS area areione or more smaller window frames, :eachaboutzzo xiBOinches, the sash of which are arranged to swing outward to an open positionto provide :room ventilation. Because these swing :outward ito "open, they provide many difiiculties, :especi-ally inithe colder months when ventilation as well asrstorm :protection is desired.

When they are coirered overfirom'thezontside by 'a storm window, they cannotiswingnuiiwaitd when desired for ventilation or other purpose. No practical solution appears :to .have .been provided for this difficulty. The same -.difiieultiesarise during the summer months whsenit :is desired :to provide screened x/tentilation for such windows. auxiliary sash is desired that may hezadapted for either winter :or summer use, :particularhr-of a type that will enable the regular window "sash to be opened when desiredwithout-difficultyior :cleaning, ventilation or other. purpose.

"sash :of practical construction which .can iheznsfid in-conjunction with :the regular sash of arframe and is adapted for use on the room side thereof.

it is arranged with appropriate linkage or :hardware, so that, when desired, it may be opened in the direction of the inside of "a :room-and-theneby provide :access to the regular :windowsash for cleaning, replacement, ventilation or-other purpose.

A feature of the auxiliary sash proposed is that 'it not only opens *into the inside of a room, butiit is so arranged that when opened *it may be .lowered into the room for purposes of cleaning, repairs, "or otherwise.

Another feature of the auxiliary sash is that invention is shown;

channel a similar channel IE, but of a greater depth is provided longitudinally of the underside of the top sash rail A frame l3, here carrying a. glass panel I9, is removably received between the several rails of sash l0 and has its upper transverse strip in the upper channel I E, and its lower transverse strip 2| in the lower channel |5. Frame I8 is held in the channels by the rear and forward lips 22 of the channels. The sash side rails [4 each include a rear inwardly extending lip 23, serving to further support Panel frame I8 is of between the channels l5 and I5, and it may be removed from the channels by first lifting it upwards to the limits of the upper channel i5 so as to free the lower strip 2| of the panel frame from the lips 22 of the lower channel I5. The frame I8 is then drawn forwardly and out of the auxiliary sash H3.

The auxiliary sash I0 is associated with the regular frame 2 in such manner that it may be drawn from a position closing the room side of the window opening to a position removed from the frame, though still connected to it, and when so removed from the frame it may be suspended in the room before the window opening in a lowered position, as in Fig. '2. In the latter position .full access is afforded through the building frame 2 to the regular window sash 8 for purposes of ventilation, cleaning or otherwise. To this end each side rail H of the auxiliary sash is individually provided with suitable'linkage, generally designated 24, associating it with a corresponding side wall 5 of the building frame 2. The

manner and means by which each side rail I4 is of the frame 2 includes an angle bracket 25, from the central area of a plate 26 of which extends at right angles a short pin 21 on which a pair of

links

28 and 29 are arranged to pivot. Link 28 comprises a pair of elongated rectangular walls 30 in parallel spaced relation to one another and integrally joined to each other by a back portion 3|, whereby a knifeway 32 is provided between the free ends of the walls. Link 28 pivots upon the pin 21 which passes through the lower ends 'of both walls 30. Link 29 in the manner of a blade pivots at one end on pin 21 between the walls 30 of link 28. A coil spring 33 carried about pin 21 and having its free ends connected to links '28 and 29 serves to constantly tension these in In this arrangement a free end 34 of the coil spring is anchored in an aperture of a pin 35 projecting from a face of link 28, the other end 36 of the spring is anchored in a similar pin 35 on a face of the blade link 29.

Links

28 and 29 are preferably of equal length, and at the free end of each is means engageable 'in a channel member 31 for up and down slideable movement in the latter. To this end, at the free end of link 28 on the outer face of the outer wall 39 thereof extends at right angles a stud, the shank 38 of which terminates in an enlarged disc 39. Projecting from the outer face of link 2.9 at the free end thereof and at right angles thereto is a similar stud the shank 49 of which terminates at its free end in an enlarged disc 4| similar to disc 39.

Discs

39 and 4| are engaged in a channel 42 of the channel member 31 and are adapted for up and down slideable movement therein, one above the other. Channel bar 31 includes an elongated back plate portion 43, the free longitudinal ends 44 of which are bent around to a position short of one another in front of the back plate where they are spaced away from the latter so as to form the channel 42 and to form an elongated opening 45 between the ends 44. The

shanks

38 and 49 of the

respective discs

39 and 4| extend from the latter freely through the opening 45 to their respective links. The channel ends 4 3 overlap the discs and serve to confine them to the channel. The arrangement is such that

links

28 and 29 in normal position are held under tension of coil spring 33 in opposite directions, so that the link ends are degrees apart, the disc 39 is extended vertically upward in the channel bar, while the disc 4| is extended downward in the opposite direction. The channel bar 31 is adapted to be fixed as in Figs. 3, 6 and 'l' in a vertical position against the inner face of a side wall 5 of frame 2 adjacent to the stop moulding 9. The channel bar extends in height from the base of frame 2 to the top wall thereof. It is secured to the inner face of wall 5 in suitable manner, such as by screws through holes 48 in the channel back. The channel opening 45 faces away from the wall into the frame opening. The angle bracket 25 is adapted to be fixed by suitable fasteners to the outer face of a side rail M of the auxiliary sash H) at a distance below the top of the rail so that link 28 when extended to its uppermost position in the channel will not extend above the top rail of the sash.

To enable the auxiliary sash |9 to be received between walls of frame 2 without having a space between the sides of the sash and the walls 5 of frame 2, as would otherwise happen because of the room taken up by the linkage 24 at the sides of the sash, the outer faces of each side rail It is angularly recessed longitudinally of a corner thereof as at 41, in such manner as to accommodate therein bracket 25,

links

28 and 29 and the associated channel bar when the sash I9 is in a position closing the frame 2, Figs. 3, 6, and 7. Bracket 25 includes a second plate 59 whereby the bracket is secured in the recess 41' by suitable screws 5| to the sash.

Now, in the manner of operating the arrangement it can readily be seen that when sash i9 is in its closed position in frame 2 and it is desired to withdraw it to its open position outside of the frame, it is held by the handgrips 4B and is drawn inwardly at the bottom toward the person, as in Fig. 7, to a position beyond the edge of the frame sill. Downward pressure is then exerted upon the sash to lower it. The sash is uniformly guided in its downward movement by the associated

links

26 and 29 have substantially knifed into one another, the sash will be limited in its downward movement and will hang suspended before the frame within the room of the building. In the latter position the auxiliary sash may be cleaned or otherwise attended to and access is provided from the inside of the room to the regular window for appropriate attention.

The auxiliary sash may be restored to its closed position by lifting it upwards so as to raise the discs in the side channels. As the discs are carried upwards the sash will be uniformly guided in its upward movement. In restoring the sash to closed position, it is preferably raised with the upper portion thereof inclined towards the top of frame 2. It is lifted in this direction until the top rail of the sash engages behind a narrow transverse moulding strip 49 affixed to the underside of the top wall of frame 2. The bottom of the sash will at this time be slightly above the sill 4 of frame 2. When the latter position is reached, the sash is then pushed back at the bottom to bring it to closed position. The narrow moulding strip 49 prevents the sash from moving forward at the top when the bottom portion thereof is being pushed backwards into the frame to closing position.

From the foregoing arrangement of the auxiliary sash. with the frame 2 and its manner of operation, a further advantage is evident, in that the sash can be moved from a closed to an open position without interference with shade rollers or Venetian blind structuresthat might be positioned at the upper forward portion of frame 2.

While I have described and illustrated a preferred form of the invention, it is clear that some modifications of form might be made without departing from the spirit of the invention, and it is my intent, therefore, to claim the invention not only in the form presented, but also in all such forms as may be reasonably construed to be within the spirit of the invention and scope of the appended claims.
