UNITED STATES GEORGE W. LANCASTER, OF RICHMOND, VIRGINIA.
SHEET-METAL WINDOW AND BALANCING SASHES.
Application filed April 11, 1923. Serial No. 831,418.
To all whom it may concern:
Be it known that Gnonoa W. LANcAs'raR. a citizen of the United States of America, residing at Richmond, in the county of Henrico and State of Virginia, has invented new and useful Sheet-Metal Windows and Balancin Sashes, of which the following is a speci cation.
The present invention has for its purpose the provision of a sheet metal window frame construction including sheet metal balancing sashes, wherein the main lintel of the frame has an upwardly formed depression, which, together with an auxiliary lintel, (which ives a finish to the window) constitutes a housing for the pulley boxings or mountings in the upper corners of the window frame. In this way the boxings or mountings are obscured, the 'boxings being fastened to the main lintel, while the auxiliary lintel is secured to the boxings, which is an-' other essential purpose of the invention.
Still another purpose of the invention is to provide a window of such standard sheet metal construction that it may be installed in buildings of various designs, during the course of their construction or subsequently.
Although it is common to emplo balancing sashes, as in the prior art well nown to the present inventor, it is the aim to use upper, lower and intermediate sashes, the latter thereof being counter-balanced, while the upper and lower sashes are weight-balanced, and since the lower sash may be locked, the intermediate sashes are locked, due to their inter-connections.
In the installation of a sheet metal window of this character, it is the aim to provide separate guides for the weights, which are freel operable without interference with eac other, and as the balancing wei hts for the upper sash may be locked or fatched, the upper sash may be locked.
As a result of this arrangement and construction of sashes it will be noted that the intermediate sashes cannot be disposed in different adjusted positions, due to the upper outermost sash being locked by its weights.
A further purpose is the provision of means for spacing arts of the pulle boxings or mountings rom the upper e ges of the guides, in which the sashes and weights are mounted, thereby preventing the u per ragged edges, if any, on the upper an s of the guides, from interfering with the boxm s.
11 order to provide a window of standard construction for installation in various designs of buildings durin their construction or subsequently, the sti es of the window frame are in the form of sheet metal casings, which are provided with interlocking means, whereb when two or more frames are interlocke a mullion is provided between the frames. The interlocking means is of such construction as to permit two or more frames to be slid into lace in the window opening, and the wal filled out around the frames, thereby permitting old, as well as new buildings to be equipped with windows of this kind.
In window frames of this character, the stiles are hollow or in the form of casings to partly receive the brickwork of the building, and to reinforce the sides of the hollow stiles transverse bars connect the sides. To prevent the bars from interfering with the interconnecting of the frames, the interlocking means have cut-away portions to permit of the reception of the bars.
'To insure a simple looking or latching for the weights, the lower extremities of certain of the guide walls of the guides for the weights are engaged by gravity latches or looks, which are carried by the weights, that is, when the weights are lowered and the upper outermost sash raised.
A still further purpose is to provide improved pulley boxings, which comprise opposed p ates, the pulley pin mountings or ournals of which are constructed so as to insure spacing means to hold the plates in spaced positions, and in such wise as to prevent binding of the pulleys, which are carried revolubly upon the pins and between the plates.
The invention also contemplates improved means for glazing or settin the glasses in the balancing sheet metal sas es, the rails of which are hollow, and in such manner as to preclude the weather, as well as to prevent rattlin It is to be understood that the particulars herein given are in no way limitative and that while still remaining within the scope of the invention, any desired modifications of detail and desired proportions may be made in theapparatus according to circumstances.
The invention comprises further features and combinations of parts, as will be hereinafter set forth, shown in the drawings and claimed.

Figure 14 discloses detail perspective views of the adjoining stile walls of the frames, showing their construction and how they ma interlock, whereby the reinforcing bars wil not act as a hindrance to the inter connection.
Referring to the drawings,
1 designates each window frame as a whole which comprises the stiles 2, the main lintel 3 and the e111 4. The stiles, the lintel and the sill are hollow, therefore, are constructed of any suitable sheet metal, preferably galvanized. Where two window frames are adjoined, as in the drawin s, Figures 1 and 5, the inner and outer wa ls 5 and 6 of the stiles are provided with inturncd-flanges 7 and 8, which adjoin, as in Figures 1, 5 and 14. The inturned flange 7 of the stile 5 on the left in Figures 5 and 14 and diagonally op osite flange 8 of the stile wall on the rig t terminate in bent flanges 9 and 10 forming channels 11 and 12. The flange 7 of the stile wall on the right and the inturned flange 8 of the stile wall on the left engage said channels 11 and 12, asin Figures 1, 5 and 14, to interlock the frames. When the frames are connected, the adjacent stiles thereof constitute a mullion 13, Figures 1 and 5. By this construction of interlocking the stiles of the frames, it is possible to install the frames in buildings during their construction, or subsequently, particularly the latter by sliding the frames in place. The opposed walls of the stiles are braced by means of transverse reinforcing bars 14. In order to prevent the bars 14 hindering the connection of the stiles, the flanges 9 and 10 have cut-away portions 15, which ermit of the reception of the bars, when t 1e frames are connected to form the mullion. Due to the stiles, lintel and sill being hollow, the brick or other wall of the building may be extended into the hollows thereof, thereby insuring holding the frames in position securely, and in such a manner as to preclude the weather.
The adjacent walls of the stiles of each window frame, close to the inner portion of the frame, are longitudinally countersunk forming channels 16, the bottoms of which are formed with longitudinal tongues 17, thereby sub-dividing the channels into vertical guides 18 and 19, for the weights 20 and 21. Also the adjacent walls of the stiles, close to their outer portions, are formed with longitudinal ribs 22. Secured by any suitable means, preferably by s 0t welding to the adjacent walls of the sti es, are plates 23, which are formed with spaced ribs 24 and 25, there being intervening channels or guides 26. These channels or guides 26 receive the lower innermost and the upper and lower intermediate sashes 27, 28, and 29. The opposed ribs 24 adjacent the outer portion of the window frame are spaced from the ribs 22, thereby causing to be formed opposed channels or guides 30, for the reception of upper outermost sash 31. The ribs 25 are opposite the guides 18, whereby their hollows may constitute guides 32, to cooperate with the guides 18 for guidin the weights 20. Secured to the inner rabbeted edges 33 of the stiles, by any suitable means, preferably screws 34, althou 11 spot welding may be used, are stile trim plates 35. These plates have portions conorming to the rabbeted edges 33 of the stiles, and are also provided with angle portions, the hollows of which act as guides 36 opposite the guides 19, to insure aiding the weights 21. It will be noted tiat certain walls of the guides 32 have extension flan es 37 extending inwardly. These extension flanges are opposite and cooperate with the longitudinal tongues 17, to retain the weights separated and guide them during their vertical reciprocating movements, when adjusting lower innermost and upper outermost sashes. The extension flanges 37 are angular-1y bent. as at 38, so as to retain the weights spaced equal to the thicknesses of the tongues 17 and so that the weights 21 may slide against certain of the faces of the extension flanges, instead of engaging their edges which would be the case, if such flanges were not so formed.
Pivoted u on headed pins 39 (which are carried by t e weights 21) are latches 40, the handles 41 of which may be used to operate the latches to release the weights. Certain side walls of the ribs are spaced from the edges of the guides 36 equal to the thicknesses of the latches, so that the latches may operate between the ribs and said edges, as the weights 21 operate vertically. The latches have openings 42, thron h which ins 43 (which are carried by t e weights extend, thereby permitting the latches to have limited movements, sufliciently to enable the hooks or shoulders 44 of the latches to engage with the lower extremities of the extension flanges 37, when the weights are in their lowered positions and the upper outermost sash is raised.
The main lintel 3 is hollow and constructed of sheet metal and formed with a broad upwardly protruding depression 45 extending the length of the lintel. Mounted in the ends of the depression are pulley boxings 46, each of which comprises the opposed plates 47 and 48. The plates 47 have upper and lower longitudinal flanges 49 and 50. Suitable bolts or other fastening means 51 ass through the flanges 49 and the bottom 0 the depression to secure the boxings in position. In order to give the main lintel a finish, and to obscure the boxings, an auxiliary lintel plate 52 is secured by screw bolts 53 to the flanges of the boxings, so as to cover the depression. The inner edge portion of the auxiliary lintel plate has an angular flange 54, which engages with the inner portion of the main lintel, as shown. The outer wall of the depression has a rabbet 55, while the outer edge portion of the auxiliary lintel plate is formed with an angular part or rabbet 56, the bottom wall of which engages the rabbet 55. Obviously, the opposed rabbets 55 and 56 constitute a channel for the reception of the upper rail of the upper outermost sash 31, when in a raised position. Spacing and journal pins 57 and 58 connect the plates 47 and 48, by swaging the reduced ends 59 in the plates 47 and 48, as at 60, thereby holding the plates rigidly parallel. The journal pins 58 also act as spacing and holding means for the plates. 4
The side, top and bottom rails of each of the sashes are hollow and are constructed of sheet metal. Th sheet metal of each rail is bent to form a rabbet 61 to receive the glass 62. Each rail is formed with a channel 63 for the reception of a hollow bead 64, which is provided with a flange 65 to enter a groove 66 formed in the bottom of the channel under the rabbet 61. Each retaining head is sprung into position for glazing the glass in the sash. The sheet metal of the rails, after being bent to form the shaped in cross-section shown in Figure 2, is overlapped and spot welded or otherwise connected. Adjacent where the metal is overlapped, the lower rails of the sashes 28, 29 and 31 are formed with upwardly bent tongues 67, which are parallel with said lower rails. The upper rails (adjacent where the sheet metal thereof is overlapped) 01:: the sashes 27, 28 and 29, are also formed with tongues 68, (which are parallel to the rails) to engage between the tongues 67 and the lower rails of the sashes 28, 29 and 31, thereby interlocking the sashes. The vertical and horizontal rails'of each sash at the corners thereof are mitered and spot welded or otherwise connected, as shown in Fig ure 8. s
Revolubly mounted on the 58 are pulleys 69, 70, 71 and 72, and passmg over the pulleys 69, there being only one shown, is asash cord or chain 73, one end of ,which is attached between the ears 74 of the welght 71, as at 75, and its other end connected to the reversely disposed hook ears 76, which are secured to the upper outermost sash 31, in any suitable manner, as at 77. However, in connecting the chain 72 or sash cord to the sash 31, it is first passed over the pulleys 69 and 72. Connected to the upper rails of the sashes 28 and 29 by reversely disposed hook ears 76 and passing over the pulley 71 is a sash cord or chain 78, for permitting the sashes 28 and 29 to counterbalance. Also connected by means of reversely disposed hook cars 76 to the sash 27 is a sash cord or chain 79, which passes over the pulley and is in turn connected at 80 between the cars 81 of the weight 20, thereby counter-balancing the lower innermost sash 27 with the weight 20.
The opposed plates 47 and 48 of the pul- Iey boxings have cut-away portions 82 to receive the angular or rabbeted part of the auxiliary lintel plate, when the same is arranged in place.
.In Figure 7 of the drawings, the inner journal pins and outer walls of the stiles have inturned flanges 83. In order to obtain the same fastening result of the st1les, as m Figure 5, the inner wall 84 of the stile on the left and the outer wall 85 of the side on the right have secured to their lnner faces bv spot welding or the like, plates 86 and 87, which are bent over and engaged with the flanges 83. The bent over parts of said plates 86 and 87 are to be provided with cut-away portions (not shown) similar to the cut-away portions 15, to receive the bars 14", so that the bars will not interfere with uniting the stiles.
When the sashes and the weights are disposed, as in Figure 2, the lower innermost sash and the weight 21 latched or locked,
the other sashes are correspondingly locked. Obviously, the lower innermost sash may be locked by a latch 88 which engages a keeper 89, which is fastened in any suitable manner on the sill of the window frame, as in Fi res 1 and 2.
y grasping the handles 41 of the latches 40 simultaneously and pulling upwardly thereon, their hooks or shoulders are disengaged from the lower extremities of the extension flanges 37, which will permit the weights to be raised and the upper outermost sash lowered. The other sashes will remain locked, as long as the lower innermost sash remains latched. However, as soon as the latch 88 is released, the lower innermost sash may raise, in which case all of the sashes are free to be adjusted as may be desired. The lower innermost sash may be released and raised, without releasing and raising the weights 21, and as a result of this it is obvious as to how the other sashes may be manipulated, for instance, in a manner previously set forth.
