4 claims. (ci. 18s-76) This invention relates to housing or building construction and more particularly to a combination metal storm sash and screen adapted to be easily applied to existing structures whereby maximum protection against the elements, convenience, pleasing appearance, and ease of operation are assured.

Heretofore many devices of this nature have been produced but the majority of these are relatively expensive to construct and install and also incorporate various types of catches and the like which are quite apt to be beyond the ability of an ordinary housewife to manipulate.

It is therefore an object of this invention to provide a combined metal storm sash and screen oi' relatively inexpensive construction in which the majority of parts are extruded metal shapes and which may be easily fabricated for application to substantially any size of building opening.

It is a further object of this invention to provide a combined metal storm sash and screen in which provision is made for storing the screen during the winter months and for storing the storm sash during the summer months, all as a more or less integral unit and without the necessity of providing storage space elsewhere in the building for these parts.

It is a further object of'thisinvention to provide a combined metal storm sash and screen in which the various movable parts are securely held in position against rattling and in which an eifective seal against the elements is provided.

It is a further object of this invention to provide a combined metal storm sash and screen in which the frame may be assembled by the insertion of six screws or other equivalent fas.- tening elements and in which the storm sashes or screen may be removed from the frame or installed therein from the inside without the removal or introduction of fastening means or other elements which might easily become mutilated or lcst.

It is a further object of this invention to provide a simple, yet effective means for securing together the sash parts at the corner of the sash.

Another object of this invention is to provide an improved method of fabricating a metal frame for a storm sash and screen.

Further objects and advantages of the invenf tion will be apparent from the following specification taken in coniunction with the accompanying drawings, wherein:

Fig. 1 is a perspective view from the outside of a building and showing the device of this invention in position in a window opening therein; Fig. 2, a longitudinal sectional view showing the screen in operative position and the storm broken away for greater clarity;

Fig. '7, a detail sectional view showing the manner in which the upper corners of the frame members are secured together;

Fig. 8, a perspective view-of the corner joining and clamping member;

Fig. 9, a perspective view of the extruded member forming the lower portion of the frame side rails;

Fig. 10, a horizontal sectional view showing the upper sash in raised position, the lower sash in operative position, and the screen in storage position;

' Fig. 11, a perspective view of the upper storm sash;

Fig. 12, aperspective view of the lower storm sash; and

Fig. 13, a perspective view of the screen; and

Fig. 14, a perspective View of the joint at ea"h corner of the sash with parts broken away for greater clarity.

With continued reference to the drawing an outer frame I0 having side rails` II. upper cross member I2 and lower cross member I 3, is provided to support upper storm sash I4, lower storm sash I5, and screen I6, the complete assembly being adapted to be received in window opening I'I or the like in the outer wall I8 of a building.

As best shown in Fig. 11, the upper storm sash I4 comprises side rails I9, upper cross member 20, and lower cross member 2|. The rails and cross members are of channel construction and when assembled in rectangular form, as shown in Fig. 11, enclose and support a pane of glass 22. The lower cross member 2| of the upper storm sash I4 is provided with a reinforcing strip 23, the inner portion of which is turned up, as at 24, to overlie the inner surface of the lower cross member 2I, the portion 24 serving to fill the space between the upper sash I4 and the lower sash I5.

Lower storm sash I5, as best shown in Fig'.`l2, is formed of side rails upper cross member 26 and lower cross member 21. The side rails and cross members are of channel construction and serve, when assembled VVin rectangular form as shown in Fig. l2, to retain a pane of glass 28 therebetween. In order to assist in raising, lowering, or other manipulation of the lower storm sash I5, there is provided on the lower cross member 21 thereof a finger-engaging ring 29 pivotally secured to the lower cross member by an attaching plate 36 and screw threaded or other fastening means 3 I.

The siderails and upper and lower cross members of the upper storm sash I4 and lower storm sash I5 are secured together in a simple and emcient manner which greatly facilitates the quick and easy assembly of the parts. This fastening means as best shown in Fig. 14 comprises an anchor member 81 having tapered leg portions 88 and 89.

The channel members forming the side rails and upper and lower cross members of the sash are provided with inwardly extending opposed flanges 99 and 9i spaced from the bottom 92 of the channel. In assembling the parts to form the sash the tapered leg portions 83 and 89 are inserted in the space between anges 98 and 5I and bottom 92 of the channel with sufcient force to insure a tight frictional contact therebetween, this contact being sufficient to hold the parts in assembled relation along the miter joint 93.

It will be observed that the channel members are arranged so that the groove thereof opens into the inside of the sash to receive a pane of glass. The anchor member is formed with substantially parallel sides that snugly t within the sides of the channel without spreading the channel sides apart. The outer surface of each leg of the anchor member extends at substantially the same angle as the corner of the sash and is shown as a right angle in the drawings. The inner surface of each leg 88 or 89 of the anchor member 81 converges from the vertex of the anchor member towards the free ends of the legs providing a wedging action between the bottom of the channel and the flanges which serves to maintain the sash in assembled relation.

The taper in the legs of, the anchor member is such that a substantial length of the flanges and a substantial length of the bottom of the channel tightly engage the anchor member producing a secure joint.

It is thus seen that by this structure there is provided a very simple yet eicient means for facilitating the assembly of .the parts and for securely holding them in assembled relationship.

Screen I6, as best shown in Fig. 13, is composed of side rails 32, upper cross member 33, and lower cross member 34. The side rails and cross members are secured together in rectangular form at the corners thereof by welding or the like and each of these members is also provided with an outwardly extending peripheral ange 35, the purpose of which will presently .be described. Screen wire 36 may'be secured to the side rails and cross members in any desired or well-known manner.

The frame I0 of this device comprises a right hand side rail 35, a left hand side rail 31, upper cross member 38, and a lower cross member 39.

shape, the metal employed preferably being alumin'um, but obviously any other metal sufficiently light in weight and corrosion resistant would be equally usable. Customarily extruded shapes are produced in relatively long lengths, and since the majority of the frame of this invention is fabricated from the same extruded shape, obviously the construction thereof is relatively economical in view of the fact that only one shape is necessary for the majority of the frame, the required pieces being merely cut off from an extended length thereof. Each of these pieces must be modified to a certain extent, but such modification is considerably less expensive than would be the production of a plurality of different individual shapes or pieces to make up the complete frame.

The basic extruded shape from which the side rails and upper cross member are fabricated may be best understood from an inspection of Figs. 4, 5, 6 and l0 wherein is shown a structural member comprising an outer wall 40 having an outer inturned or marginal flange 4I and an inner inturned flange 42. In order to further strengthen the wall 40 there is provided between flange. 4I and flange 42 a strengthening rib 43 formed integrally with the wall 48. Wall 4I) extends inwardly for a small distance beyond flange 42 to provide an outerrail or rib 44 and an inner rail or rib 45 is provided adjacent the inner edge of the flange 42 and integral therewith. Midway between rail l44 and rail 45 there is provided an additional rib 46 integral with ange 42,- the space between rails 44 and 46 providing a trackway to accommodate sash I4 and the space between rails 45 and 46 providing a trackway to accommodate the lower sash I5. In order to further strengthen the flange 42 there is provided thereon and integral therewith directly opposite the rail 45 a strengthening rib 41.

The inner edge of the flange 42 is formed with a relatively narrow channel or groove 48 provid-4 ing a trackway to accommodatethe flange 35 of' the screen I6.

The outer surface of the wall 48 may be provided with longitudinal grooves 43 or other decorative markings in order to enhance the outward appearance 'of the frame.

The basic extruded shape from which the side rails 36 and 31 and the upper cross member 33 are fabricated need not be modied in any way to form the upper cross member 38 except that Side rails 36 and 31 and upper cross member 38 are formed from the same extruded` metallic the ends thereof are cut at an angle as indicated at l5I) to form a miter joint with the upper ends of the side rails 36 and 31. The basic shape formA ing the left hand side rail 31 is modified to the extent that the inner wall 5I of the relatively narrow trackway 48 is removed from the lower end of the side rail 31 to a point 52 slightly above the midpoint of the side rail. The inner wall 5| of the relatively narrow trackway in the right hand side rail 36 is also similarly removed. The basic shape forming the right hand side rail 36 is further modified by removing the ribs 45 and, 46 from the upper end thereof to a point 531 slightly below the midpoint of the side rail 36- The basic shape forming the lower cross memberV 39 is only modified to the extent of providing-- slots 54 therein to accommodate the ribs 45 andv 46 when the lower cross member is assembled l between the lower end of the side rails 36 and 31..

It will thus be seen that the only stock neces-- sary to fabricate the frame for this combined storm sash and screen comprises two extruded metal shapes which may easily be cut up intos y the appropriate'lengths for each memberV of the frame, slight modification of these various lengths and assembly being all that is necessary to fabricate the frame, thus resulting in a relatively small stock inventory and a minimum of machine Work and labor to complete the frame.

The miter joint D uniting the upper end of each side rail with the upper cross member 38 is accomplished in a novel manner by utilizing a joining and clamping member 55 best shown in Fig. 8, the application of which is best shown in Figs. 5, 6 and 7. The member 55 comprises a joining portion 56, a clamping portion 51 and a relatively thin connecting web 58. The portion 51 is provided with contiguous. right angular surfaces 59 and 60 which when assembled in the frame are adapted to contact the inner surfaces of the marginal flanges 4I adjacent the joint 50. In order to securely hold the side rails and upper cross member .together apertures 6I are provided in the joining portion 55 for the reception of screw threaded fasteners 62 or the like which extend through the marginal flange 4I and into the apertures 6I thus securely fastening the side rails and upper cross member together at the joint 50.

In order to prevent spreading of the inner anges or legs 42 at the inner end of the joint 5U, the clamping portion 51 is provided with contiguous right angular faces 63 and 64 which are adapted to contact and embrace the surfaces 55 of the inner anges or legs 42 wherebyseparation thereof is prevented. In order to accommodate the strengthening ribs 43 the connecting web 58 is provided with a recess 56 adjacent the joining portion 56, the recess 66 serving to receive the ends of the ribs 43 at the joint as shown in Figs. 5, 6 and 7.

It will thus be seen that by provision of the joining and clamping member 58 there is. provided a simple and economical means for securing a rigid miter joint between two members substantially rectangular in cross section and in which only two fastening means are required to secure the joining and clamping member in place to complete the joint.

The lower cross member 39, the'desired length of which is cut from an extruded shape, is a generally channel shaped member provided with an internal strengthening rib 61 and outer and inner flanges 68 and 69 respectively. The upper surface of the lower cross member 39 is inclined downwardly as at to provide adequate drainage and this upper surface is also provided with an outwardly facing shoulder 1I against which the inv ner side of the lower sash I5 is adapted to abut. Adjacent the inner edge of the lower cross member 39 there is provided a relatively narrow groove 12 which is adapted to receive the lower peripheral flange of the screen I6 when the screen is in lowermost position. The upper sash I4 is held in its normal raised position by fastening means 13 which may conveniently take the-form of pins 14 slidably mounted inapertures in brackets 15 f secured to each end of the lower surface of upper sash I4. Pins 14, when extended, are adapted to project into apertures 16 provided in side rails 36 and 31, it only being necessary to withdraw the pins 14 when it is desired to lower or remove the upper sash I4 from its normal raised position.

Means in the form of friction clamping memy bers 11 are provided for securing the lower sash I5 in any desired position and for preventing undue rattling of this sash in the frame under the.

action of the forces of nature. Clamping means 11 may conveniently be. pivoted to the side rails 36 and 3'1 by a rivet or the like 18 extending through the clamping member and into the rib 45. The clamping member 11 is provided with an actuating finger engaging portion 19 and a clamping portion having a tapered or bevelled inner edge 8| which is adapted to engage between the side surface of the rib 46 and the inner surfaces of the side rails 25 of the lower sash I5 whereby the lower sash is jammed or clamped against the. rib 46 to retain the same in place at any desired elevation or to prevent rattling thereof whenv in lowermost position.

It is to be noted that the clamping members 11 are formed from a flat sheet metal stamping, the major portion of the member being in one plane and only the portion. including the .bevelled edge 8l being offset to permit mounting on the outer side of rib 46 and at the same time provide for the engagement of bevelled edge SI with the rear surface of the rib and the side rails of the lower sash.

In order to retain the lower sash I5 in its extreme upper position whereby maximum window opening may be obtained during the summer months, there isy provided on the lower cross member 2| of the upper sash I4 a hook shaped supporting member 82 having a portion 33 which is adapted to engage the lower surface of the lower cross member 21 of the lower sash I5 and support this sash in raised position.

In order to retain the screen I6 in its extreme upper position as during the winter months, the upper cross member 33 thereof is provided with a spring catch 84 having a portion 85 which is adapted to snap over the inner edge of the upper cross member 38 of the frame I0 to frictionally retain the screen in upper position, it only being necessary to apply a slight downward force in order to disengage the catch 84 to permit movement of the screen to lowermost position.

In order to prevent the entrance of insects or the like between the screen I6 and the lower sash I5, there is provided on the outer surface of the upper cross member 33 of the screen a resilient strip 56 formed of rubber or the like and extending throughout the entire length of the upper cross member, the strip 86 being adapted when the screen is in lowermost position to engage the Vinner surface of the lower cross member 21 of the lower sash I5, thus providing a seal therebetween.

The provision of the joining and clamping means 55 permits a simple. and novel method of assembly of the frame which may be accomlplished by securing the member 55 in place to either-the upper cross member 38 or one of the side rails 36 and 31 and thereafter bringing the other member into position and securing it to the member 55 thereby completing the joint. The joint may also be assembled by bringing the side rails and upper cross members into juXta-position and thereafter applying the member 55 to complete the joint although the first described method is preferable.

The complete method of fabricating the frame is also very simple and novel in that it is only necessary to provide two types of extruded stock from which the various parts are cut in the required lengths, certain of the parts `being thereafter modified to*` provide the necessary structural features therein. The side rails and upper cross member are then assembled in the manner described above and the frame completed .by introducing the lower cross member between the lower ends of the side rails and securing the same in place by screw threaded fastening means or the like B extending through the inner wall EE of the lower cross member 39 and through ribs 45 and 46; thus completing a rigid structure secured together by only six fastening elements.

The frame is applied to the window opening of a building adjacent the outer surface thereof, as best shown in Fig. l, and may be secured in place by screw threaded fasteners or in any other desired or convenient manner. The entire as sembly is intended to be left in position the year round and by the structure described above provides storm sash for winter use and storage space for the lower storm sash whereby the lower portion of the window may be opened and covered with a screen for ventilation during the summer months or at any other desired time, the screen also being secured in a raised out of the way posin tion during non-use thereof, as during the winter months, it being only necessary to exert a slight townward force thereon in order to move the s creen into operative position.

The upper and lower sash as well as the screen may be easily removed from the frame at the inner side thereof, the screen by raising the same slightly until the lower ange 35 is out of engagement with the groove 'i2 in the lower cross member 39 whereby the lower portion of the screenv may be tilted inwardly and the screen removed from the' frame due to the termination of the trackway 48 at the point 52 slightly above the midpoint of the side rails. The lower sash may be removed by raising the same to a position I wherein the lower cross member 21 thereof is above the termination of the'rib 46 in the right hand side rail 3S whereupon the right hand side of the lower sash may be tilted inwardly a sufficient distance to remove the entire sash from the frame. The upper sash may likewise be removed from the frame by withdrawing the pin i4 from the aperture 16 and lowering the sash slightly until the upper cross member 2i) thereof is out of engagement with the groove formed by f.

ribs 44 and 43 whereupon the right hand side of the upper sash I9 may be tilted inwardly a sufficient distance to permit complete removal of Athe sash from the frame.

It will thus be seen that by the structure above described there has been provided a relatively `simple and inexpensive construction which when applied to a building presents a pleasing appearance and one which is not subject to excessive weathering or deterioration and in which provision is made for the easy manipulation of storm sashes and a screen for proper use thereof at all times of the year, depending on the climate or weather at that particular time, and in which the sashes or screen may be removed from the inside of the building in order to clean or effect repairs thereon.

It will be ovious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is shown in the drawings and described in the specification but only as indicated in the appended claims.
