3 Claims.

Our invention relates to storm window constructions which are removably attachable to standard or slightly modified window frame structures.

An important object of our invention is to provide a window construction which is light in weight, rigid, strong and durable in construction which has a storm window sealably secured therein, and which is attachable from the inside of a building, as distinguished from present storm windows which are attachable to the outside of the building.

Another important object of our invention is a to provide a storm sash structure which is securable to a window frame from the inside of a building structure.

Another object of our invention is to provide bolt locking means which may be set to operative and inoperative positions in order to facilitate the insertion and removal of the storm sashes or windows.

A further object of our invention is to provide a bolt and lock mechanism which will permit snapping storm sashes into engagement, and which is settable so as to permit removal of the said storm sashes by snapping them out of engagement; thus facilitating insertion and removal of sashes, which is even more so simplified by virtue of the fact that the said storm sashes are insertable from the inside of the building structure.

A still further object of our invention is to provide storm sash structure of the aforementioned character which is simple and durable in construction, sealable against the elements, one which can be inserted or attached from the interior of a building structure, and which is of such elemental construction as to warrant economical manufacture thereof in quantity production.

Other objects and advantages inherent in our invention will become apparent from an examination of the accompanying drawings, elucidated further in the ensuing description, wherein like numerals designate like parts and in which: Fig. 1 is a perspective view of a pair of window frames to which our invention, the storm sashes, have been attached.

Fig. 2 is a longitudinal, cross-sectional view taken substantially on the lines 22 of Fig. 1.

Fig. 3 is a perspective view of an individual window frame with its own storm window pane therein, showing the storm-sash comprisingcur invention in the process of being attached there to, or removed therefrom.

Fig. 4 is a perspective view of an individual storm sash construction made in accordance with the practices of our invention.

Fig. 5 is an enlarged front view of one of the locking bolt mechanisms utilized in securing the storm sash, comprising our invention, in snapping engagement, being a view looking in the direction of arrows 55 on Fig. 2.

Fig, 6 is a cross-sectional view taken substantially on the line .66 of Fig. 5.

Fig. 7 is a transverse cross-sectional view taken substantially on the line 1-1 of Fig. 6.

Fig. 8 is a transverse cross-sectional view taken substantially on the line 8-8 of Fig. 6.

Referring to the various views, our storm window invention is generally designated 9 and consists of a slightly modified window frame construction In which is suitably rabbeted as indicated at H in order to receive snugly the sash frame designated l6 shown in detail in Fig. 4.

It is to be noted that the lower portions of the window frames at l2 and I3 are suitably grooved in order to receive the tongue-like portion I! on the storm sash [6. The groove is wider at the top to permit insertion with, and removal from, of the storm sash with respect to the window frame defining bearing surface 46 for the ledge 45 to rest thereon, and render the assembly rattle-proof. At each of its sides and preferably near the upper portion thereof, mortised portions 18 are provided, which are to be engaged in snap-on and off relationships by the bolt structure generally designated [9.

Finger cut-out clearances l4 and 15 are provided so as to facilitate removing the storm sashes from the windows whenever removal becomes desirable or necessary.

Storm sash structure [6 is made preferably of a light aluminum or magnesium metallic material, of channelled cross-sectional configuration designated 20, having sealed thereinto the glass pane 2! by means of a channelled resilient structure 22's0 as to form an adequate seal against the elements, and at the same time maintain the storm sash rattle-proof. I

The details of the bolt-locking means are indicated in Figs. 5-8 wherein it can be seen that the bolt-locking structure l9 consists of a body 23 having a bored out cavity of cylindrical formation 25, for purposes which will later appear, being also provided with a slotted portion 38 atthe top thereof in order to permit the manipulating knob 35 to be operated therein; ,the said knob 35 projecting above the slot 38. The body 23 is secured to the face of a window frame by screws 24 or other desirable fastening means.

Within the cavity 25 is mounted a cylindrical sleeve 34 which is provided with a spiral cam groove 36 extending over 180 degrees of its circumferential configuration and substantially throughout its length.

The knob 35 has a protuberance 39 which operates in the said cam groove 36; the knob sliding from left to right, to the dotted position, will cause the said tubular sleeve to rotate 180 degrees. Within the said tubular sleeve is mounted; a spring 33 coiled about the reduced body of the bolt 32 which has an enlarged portion 3| provided with a tit operating within the slot 36 of the tubular structure 34.

The enlarged portion 3| is cylindrical in construction and is provided with a bolt portion 21 and an angular cam portion 28.

The sleeve 34 is provided with a slotted portion 26 toreceive the tit or projection 38 to operate therein when the bolt 3! is cammed backwardly against the tension of the spring 33 confined in the cylindrical bore 3! thus normally maintaining the same outwardly.

The window sash at the mortised structure is provided with the rounded edges 29 which will efiectively cooperate with the cammed surface 28 when the same is either in the position shown in full lines, which is arranged to receive the sash in snap-on relationship, or when the knob is moved to the dotted position, to the right, thus rotating the bolt 180 degrees, and placing the cammed surface 28 in the dotted position so as to permit disengaging the sash [6 by a snap-off action.

Thus it can be seen that the storm windows and the bolt-locking means therefor will facilitate the tedious task formerly employed in attaching storm windows on the exterior of a building thus eliminating caulking and such other laborious tasks for weather-sealing purposes-- so vital to a construction of this type.

The window frames 10 will operate in the same normal manner, they will not interfere with the sash structures assembled thereto and may be opened or closed as desired. Likewise, when the storm sashes 16 are removed the windows will be in the same condition as they were before attachment of storm sashes and be ready for the summer, or spring seasons.

In connection with our construction, it may be advisable to improve this arrangement by placing the customary window screen in locked position in the sash frame of the window, below the lower edge of the upper window, thus furnishing a complete combination storm and screen retaining unit, which need never be changed; the storm sashes may remain in assembly permanently, since ventilation can be obtained through the screen placed underneath the upper window at the lower edge thereof, contiguously or behind the lower window and to the left thereof when viewing Fig. 2.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

Having thus disclosed and revealed our invention, what we claim as new and desire to secure by Letters Patent is:

1. In combination, a window frame having a rabbeted portion on. three sides of the internal perimetral portion thereof and a channelled portion on the bottom side, the said channelled portion being enlarged at the top portion, the channel being enlarged substantially at its top surface to define an adjacent bearing surface, a storm sash fitted removably within the said rabbeted portion and provided with an oifset tongue portion defining a ledge portion locating and engaging it removably with respect to the said channelled. portion, the tongue portion being sized to fit the channel sufficiently that the said ledge portion rests on the said bearing surface.

2. In combination, a window frame having a rabbeted portion on three sides of the internal perimetral portion thereof and a channelled portion on the bottom side, the said channelled portion being enlarged at the top portion, the channel being enlarged substantially at its top surface to define an adjacent bearing surface, a storm sash fitted removably within the said rabbeted portion and provided with an offset tongue portion defining a ledge portion locating and engaging it removably with respect to the said channelled portion, the tongue portion being sized to fit the channel sufficiently that the said ledge portion rests on the said bearing surface,

' mortises on the said storm sash, and lock means on the said window-frame engaging removably the said mortises on the said storm sash.

3. In combination, a window frame having a rabbeted portion on three sides of the internal perimetral portion thereof and a channelled portion on the bottom side, the said channelled portion being enlarged at the top portion, the channel being enlarged substantially at its top surfaceto define an adjacent bearing surface, a storm sash fitted removably within the said ralo beted portion and provided with an offset tongue portion defining a ledge portion locating and engaging it removably with respect to the said channelled portion, the tongue portion being sized to fit the channel sufliciently that the said ledge portion rests on the said bearing surface, mortises on the said storm sash, and lock means on the said window-frame engaging removably the said mortises on the said storm sash, the said lock means being automatically spring-urged and settable to receive and look the said storm sash in snap-on relationship, and being further settable to release the said storm sash in snapofi relationship.
