fmeni? fi en yffi'cfzcfa m Patented June 24, 1930 PATENT OFFICE HENRY J. SCIILACKS, OF CHICAGO, ILLINOIS WINDOW Application filed October 20, 1928.
My invention relates in general to windows and more particularly to an improvement in the type of inset windows shown in my Patent Numbers 1,625,872 and 1,724,374, and my co-pending application, Serial Number 314,- 857, filed on November 2, 1928. One of the principal objects of the present invention is to simplify the construction of such windows.
Another object is the provision of a more e'flicie'nt inset window structure which can be produced economically.
Another object is to strengthen the framework of windows of this type without in creasing the crosssectional thickness thereof.
Another object is the provision of an inset windowof standard construction adapted to fit all types of installation.
Other objects and features of the invention will be apparent from a consideration of the following detailed description taken with the accompanying drawings wherein- Fig.-1 is an elevational view of a large inset window With my improved inset window applied thereto;
Fig. 2 is an irregular sectional view taken along the line 22 of Fig. 1;
Fig. 3 is a vertical, sectional View taken along the line 8-3 of Fig. 1;
Fig. 4 is an enlarged, sectional View of the two upper corners as set along the line 4l ;of Fig. 2;
Fig. 5 is a nism;
Fig. 6 shows a modification in which the angle insert is extended entirely across the web of thecasement frame.
Fig. 7 is a fragmentary sectional view showing the addition of a felt liner to the inset frame,
Fig. 8 is a modification of the latch, and
Fig. 9 is a sectional view along the line 99 of Fig. 8.
As clearly shown in my prior patents and application above set out the inset window of my invention is adapted to be glazed along detail of'the latching mechaserial No. 313,886.
with the glass in a standard large window such as the usual double hung check rail type of window employed in residences and ofice buildings. This Window comprises a wooden frame A with glass panes B and an inset window between the panes and serving as a center panel extending from the top to the bottom rail of the large Window frame. This inset window comprises an inset window frame 0 and an inset casement frame D, which for purposes of description will be taken up separately.
The inset frame is of the'same cross-section throughout and comprises upper frame member 10, side frame members 11 and 12 and a bottom frame member 13. These four membersare mitered and welded together at the corners to form a solid four-sided structure, and having angle inserts 14 at the mitered corners welded or otherwise suitably secured in place to reinforce the entire structure. This frame being of a permanent construction is glazed into the large window with the glass panes B. A
Reference may now be had to Fig. 2 showing the frame in section, this figure showing the top and bottom members 10 and 13 respectively in cross-section. 'Theyare identical with thesections of the members 11 and 12 shown in section in Fig. 8, but the member 10 in Fig. 2 will be described as illustrating the cross-sectional structure of all of these members.
These members are preferably made of thin coppered steel bent from fiat strip form to the shape shown. This shape includes a main web 10 having one side formed up to produce a rectangular portion 10 whence the strip extends back cross the web 10 and then upwardly to form an outwardly extending flange 10. At the other end of the web 10 the material is bent at right angles to form an outwardly extending flange 10 which then extends backwardly on itself to form an inwardly extending flange 10 It is to be observed that the rectangular or enlarged portion 10 extends inwardly from the Web forming a shallow channel which allows adequate room for insertion of the angles 14. The relatively wide portion resulting from the presence of the rectangular shape of one edge of the frame forms a bearing surface for the casement frame, while the control flange 10 extending farther inwardly forms a stop for the easement thereby limiting the closing movement thereof. The edge of the flange 10 is bent back slightly on itself as shown to avoid any sharpness thereof.
The peculiar construction of the frame is adapted to fit in for use on all sides, so that it can itself be glazed into the top and bottom rails in the same manner that the ordinary window glass is, and at the same time such window glass can be glazed intothe side or upright portions of the frame. The two outwardly extending flanges 10 and 10 or more properly as applied to the side members, 11 and 11 form a channel as shown in Fig. 3 in which the glass B of the large window is glazed. This is done simply by inserting the glass and applying a narrow layer of glazers cement or putty 16 on the outside ed e of the glass within the channel. At the top of the window the flanges 10 and 10 are extended upwardly into the glass groove in the check rail and screws 17 are extended through the web lO 'into the check rail to hold the frame in position. At the bottom the lower rail in step out forming a shoulder against which the flange 13 rests. The frame is held in position at this point by screws 18, and putty 19 is formed in a bevel to present a finished appearance and make the installation water and air tight at this location. The bottom strip of the frame is provided with the usual weep holes 21 at proper distances.
Returning now to the sash or casement frame this is composed of four sides including a top member 22, side members 23 and 2% and a bottom member 26. These members are of the same cross section and accordingly a description of the cross sectional shape of one member is adequate for all. Referring to the member 22 this comprises a web 22, right angular members 22 and 22 and further right angular projections 22 and 22 parallel with the web 22. Both of these side projections extend in the same direction, the inner one being somewhat wider than the outside has a narrow continuous projection 22 resulting in the formation of a closed area having a number of utilities which will be pointed out.
The inset window glass 27 is glazed in the casement in a manner which will be made clear and its edges extend into the channel like inside portion of the casementfframe and the glass lies against the edge. of the inside projection 22. In order to" form a strong frame and at the same time permit facile glazing, corner inserts 28 are provided Shaped to fill up the closed area of the casement frame. This reinforcing inset is brazed or welded to the casement frame members, and these members being mitered at the corners are also welded together to form a substantially unit structure.
F or glazing the inset casement two of the angle inserts 28 are formed in two parts, each part being welded into its respective frame member. (Fig. 4.) A single large screw 31 is then employed to secure these two legs of the insets together to form a substantially integral. structure. This arrangement results in the production of an integral threesided frame having the third side removable therefrom. The screws 31 extend through the "'eb of the horizontal members into the angle inserts and have their heads countersunk to avoid any possibility of binding against the inset frame. Any one of the four sides of the easement may be made to be removable for glazing purposes, but I prefer to employ for this purpose the vertical member bearing the latching mechanism, as less strain is put on the screws than ifthe hinge side were removable, and the arrangement makes it easily possible to glaze the easement in an emergency while it is hinged to the inset frame. 2
As a further strengthening means a reinforcing tube 82 is placed in the closed area along the vertical hinge bearing casement member 23, this tube being framed of suitable material such as copper, steel or brass, and being brazed or welded into position preferably at the top and bottom and at one or more intermediate points. This tube extends the full length of the member 23 and the top and bottom adjacent angle inserts 28 have their vertical legs 28 rounded to extend into the opening in the tube and so merease the strength of the structure at these two corners. Preferably the legs 28 are welded or. brazed into the ends of the tubes, and the tubes themselves are also welded or brazed against the inside of the upright member 23. The use. of this tube in this fashion increases tremendously the strength of the frame at this point where it is needed, without adding greatly to the weight of the swing casement. Such weight as is added, however, is close enough to the pivot point about which this member swings so that there is no magnifying thereof such as would take place if it were farther away from the pivot. This tubular insert may be employed in the other members making up the casement frame if desired, but I have found that in all cases with which I have experimented up to now adequate strength is obtained without reinforcement other than shown at these points.
The members making up the inset frame and the easement frame are shaped so that when the leg 22 is pressed against the casement stop 10 the projection 22 (or 23 24 or 26 as the case may be) extends outwardly so as to seal off the joint between these members and prevent the possibility of moisture entering at this point. With the members in this position the inside portions of both the inset frame and casement frame are flush with each other as the drawings show. This produces a neat, attractive, but efficient and weather proof joint when viewed from either the inside or the outside. Advantage is taken of the flush character of the two frame pertions to provide hinges 3333 which are secured in position by welding or brazing the leaves to the members 11 and 23 respectively,
the hinge pin'being removable for separating the hinges and removing the easement. If desired, however, any other structure may be employed to secure this same effect.
I provide a latch mechanism also of simplified character, this latch mechanism comprising an eccentric latching member 34 having an integral pin 36 of circular cross-section as it extends through a steadying block 37 and square at the end for receiving a handle 38 secured thereto by a key 39. The pin 36 also of course extends through the sash frame and has a spiral compression spring 41 secured between the handle 38 and the sash frame and encircling the pin 36. A slot 42 allows the eccentric point 3 B of the eccentric 34 to be extended behind the square projection on the inset frame to fasten the easement. The spring ll places a tension on the eccentric 34 causing its point 34? to bear against the inset frame and thus not only prevent rattling of the easement but also to avoid the possibility of the latch accidentally becoming unfastened.
In Fig. 6 Ishow a modification wherein the insert 128 has an extension 128extended entirely across the web ofthe casement frame with the exception of a narrow slot into which the edge of the glass extends. This construction may be preferred in certain cases and is slightly stronger than the construction shown in the main form. From the point of view of construction I consider that the extension 128 1s in a sense simply an addition to the insert shown in the main form instead of being an alternative form as might be supposed. In other words there need be no difference in the construction whatsoever shown in Fig. 6 and that shown in the main figures except the addition of the extension 128*.
Under certain circumstances it may be desirable to hold the glass more securely than can be done with the relatively shallow glass groove shown in the drawings. Local regulations and ordinances for example may set an arbitrary rule which must be followed. WVhatever the reason may obtained. I
, ing cam 51 provided with a hub 51 which extends above the spindle 49 and projects out be I can obtain satisfactory results by employing a binding strip 43 around the edge of the glass pane, this binding strip being of suitable material such as sheet steel and I having the glass secured in it, itself being secured by suitable cement in the casement groove. I
Fig. 7 shows the addition of a felt line 46 to the channel portion of the inset frame. T his may or may not be used depending upon the particular installation. It may be ap-' plied in any way but the simplest and what I consider now the best way of fastening it in is by means of a water proof glue. It makes the window still more air tight than it can be made without the use of the felt. and also is very efficacious as a silencer.
In the modified latching arrangement of Figs. 8 and 9 a bearing block l? is welded or otherwise secured in the closed area of the easement frame in the manner shown. This bearing block is made approximately three inches long, although the length is not of prime importance, and at the top thereof a right angular portion 47 is provided to close off the space above the latch and an upwardly extending portion t? lies along the outside portionof the frame member and is secured thereto so that a strong durable structure is A handle 48 is'provided with a spindle 49 which extends through an aperture in the outside web of the frame and has its'nend journaled in the bearing block 4:7. A latchthrough the opening in the frame, so that the latching cam is secured against turning with respect to the handle by the insertion of a pin 52, this pin extending in the manner shown through the latching cam hub and the latching spindle. In order to secure the requisite tightness and obtain a spring engagement-between the latchingcam and the member against which it engages a spring washer 53 is disposed about the spindle 4-9 between therear face of the latching cam and the bearing block 47. a
A; suitable slot 54; is provided in the casement frame to receive the end of the latching cam for securing the window against opening.
Among the advantages of my, present structure overthose shown in my previous invention above referred to are that with this form I am able to employ thin strip material in sheet form and bend it to the shape shown so that theframe throughout is as small or smaller than the other forms and a high degree of strength is obtained. Ihis form is of particular use in largeoflice buildings but of course may be employed withgood results with any usual type of window construction. I have described many detailed features of the invention to enable others skilled in the art to practice the same but many of these features are shown in modified form in my prior cases. Those shown here for the first time are illustrated as one embodiment only of a novel concept which may have other and broader applications. Accordingly it is not desired to restrict or gauge the scope of the present invention from a consideration of the preceding description, but such invention is defined in the appended claims.
l/Vhat I claim as new and desire to protect by Letters Patent of the United States is:
'1.
