SIDNEY U. BARR, OF BROOKLYN, NEW YORK.

:DOUBLE-RUNS: WINDOW.

Application led November 25, 1922. Serial No. 603,309.

To all 'whom t may concern:

Be it knownthat I, SIDNEY U. BARR, a citizen of the United States, and aresident of the city of New York, bo-rough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Double-Hung Window, of which the following is a full, clear, and exact description.

This invention relates to window frames and sashes and particularly to what is known as a double hung window andhas for an object to provide-an improved construction wherein means are presented for permitting the window sashes to be raised and lowered readily and at the same time provide a substantially `air and water-tight structure when .the sashes are closed.

Another object of the invention is to provide an improved metal window frame and metal sash co-acting therewith which is constructed out of certain' shaped members formed so that they maybe out to different lengths and assembled inthe same manner to accommodate diderent widths and heights of window openings.

A still further objectfof the invention is to provide an improved -construction of sash support and means. for holding the sash tightly when closed while supporting the same freely when open.

In the accompanyingdrawings v Figure 1 is an elevation of a window frame and a pair off sashes embodying the invention, certain partsl being broken away for better illustrating the construction.

Figure 12 is a top plan view of the sill 70 of the window frame illustrating particularly the location of the apertures for receiving the tenons or tongues on the side jambs.

'Figure 13 is a sectional view through Fig- 75 ure 6 approximately on line 13 13.

Figure 14 is a top plan view of .one end of the head jamb with the angle fitting shown in Figure 11 illustrated' in dotted lines.

Referring to the accompanying drawings by numeral, 15V and 16 indicate the respec tive side jambs, 17 the top section or jamb and 18' the sill or the bottom jamb. The sill 18 as' particularly illustrated in Fig- 85 ures 6, 12 and 13 is provided with a raised inclined outer wall 20 and also a slightly 90 inclined inner wall 21. It will also be noted that the outer part 22 is inclined so that the water may freely run ofi and pass over From the wall 21 the sill extends to an inner flange 95 24, the portion 25 being provided with a grooved portion for receiving a projection Near each end of the sill 18 are a. pair of aperturesv 27 and V28, said apertures being designed 10o to receive the tongues or tenons 29 and-'30 respectively.l These tongues or tenons exf tend from the side bars 15 and 16 and are provided with apertures through which the draw keys or gibs 31 and 32 extend, said 105 gibs being illustrated in detail in Figure 8.

It will be noted that the bottom of these gibs are straight'and fiat and the tops are provided with a rounded surface 33 so that they will draw the parts tightly together desired, may be and produce a locking structure which, if further secured by being welded or brazed.

The side bar 16 is of a particular shape in cross section as illustrated in Figure 4. The jamb l5 is of the same shape so that the description of one will apply to both. From Figure 4 it will be seen that the jamb 16 is provided Awith a flat body section 34 which 'at the center is pressed for forming a longitudinal groove 35 for receiving the parting strips 36 and 36', which strips are held in place by suitable screws 37. 0n the inner edge of the body 34, a flange 38 is provided merging into an edge flange A39 'while the body 34 at the outer edge is pro-V vided with an enlargement 40 which acts as a molding retaining strip for producing a nice appearance and at the same time a shoulder 41 with which the top sash co-oper ates or co-acts. From Figure 4 it will be seen that by reason of the shoulder 41 and the parting strip 36, a guiding structure is presented for readily guiding the upper sash in its up and down movement. The enlargement 40 is bent into a desired shape as shown in Figure 4 which eventuates in an outer edge flange 42. The flanges 39 and 42 receive edge portions 43 and 44 of the housing 45 which housing is preferably of thin metal and acts as a housing for the weights 46 and associated parts. Co-acting guiding molding 47 which is held in place by suitable screws 48, said guiding strip with the parting strip 36 presenting a grooved or guiding structure for the lower sash whereby it may freely move up and down in the proper manner.

As illustrated in Figures 6v and 7, the parting strip 36 is divided near the center so that the'lower part 36 may be removed without molesting the upper part. At the part 36 of the parting strip, the side jamb 16 is formed with a removable section 16 which is provided with ears or flanges 49 and 50 for receiving. suitable screws whereby this section maybe clamped in place. When it is desired to apply or remove a weight, the portion 36 of the parting 'strip is removed, the molding strip '47 is removed and then the section 16 is removed. Access ma then be had to the weight 46.

The rame at the bottom is held together by the gibs 33 as heretofore described and particularly illustrated in Figures 6, 12 and 13. At the top, however, a different structure is provided-which consists of an angle fitting or knee 51 arranged at each end of the head jamb on the outside of the side jambe as illustrated particularly in Figures 3, 5, 11 andI 14. This fitting is provided with a mainor body portion 52 secured to the head iamb by suitable screws extending' vertically while suitable horizontally positionedscrewswith the parting strip 36 is aextend through the depending flange 53 and -the top rail of the top sash whereby said top rail'is crowded over. against 'the parting rail 36 when the top sash is closed, thus providing a Vtight connection to prevent air or water from passing through and also to prevent any rattling of the sash.

As illustrated particularly in Figures 1, 2 and 4, a housing 45 is provided on each side of the window frame, said housing extending over the head j amb thereof a short distance whereby the weights 46 cha-in pulle s and other parts associated therewith will e protected against dirt and ldust from Vthe Wall. Preferably, this casing or housingis merely held in place by the turned over portions or edges 42 and 43 if desired, other fastening means may be used without departing from the spirit of the invention.

In order to provide a support for the window sashes whereby the sashes may be bala'nced by the weights 46, a certain construction has been provided as shown particularly in Figures 2 and 5. In the head jamb 17 there is vprovided a pair of apertures 57 and 5S near each end, said apertures accormnodating the respective pulley housings 59 and 60, which housings may through the e openings when being mounted in position. It will be noted that each ofv the housings is provided with an overhanging portion or shoulder 61 adapted to rest on the outer end portion 62 of the head jamb 1 7 while the end 63 of the housing is clamped to the bar 64 by a suitable screw 65. A thin trimming strip 66 is also held in place by the screw 65, said trimmingY strip snugly fitting the respective apertures 57 and 58. The bar 64 has one end resting under the shoulder 67 of the enlargement 40 while the yopposite end is secured in place by a suitable screw 68. It will be noted from Figure 2 that. the. respective screws connect. the

ends 63 of the respective housings 59 and 60V to the bar 64 so that they are properly held in place. A pulley 69 is journaled on a suitable shaft 70 carried by the respective housings 59 and 60, said pulleys accommodating the respective chains 71. One end of 4.the chains 61 is Asecured in any desired manner to` the weight 46 while the oppositevv end j is passed over a. hook 72.' This hookprojects from a plate 73 rigidly secured to the sash by rivets or other means. A pair of upstanding stiffening webs or ears 74 are carried by the plate 73 near the up er end. If desired a pin 75 couldbe exten ed through 52, said `extension extending intotheY be passed upwardly the ears 74 and through the stiles of the sash. It will be noted that the upper end of f the plate 74 is provided with an aperture 76 through which one of the keys or gibs 83 extend. It will be also noted that the upper end of the plate 73 projects through a suitable aperture 77 formed in the topl rail 78 of the Window sash Awhereby the gib 83 not only locks the top rail of the Window sash to the stile thereof but also connects the plate 73 with the top rail.

As indicated in' Figure 3, the pulley housing 60 is bent at an angle so as to give more space for the weights without moving the sash chains further apart. It will also be noted from this figure that a rod 7 9` is secured to the head jamb and to one of' the angle fittings 5l by a suitable screw, said rod 79 supporting a plate 80 of thin sheet metal, which plate loosely depends or hangsin the casing 45 and acts as a spacing or separatingmember for the weights whereby they will not become entangled.

The upper sash is provided with a top rail 78 as shown in Figures 2 and 9 which is formed with an aperture 77 atI each end and also an aperture 77 at each end, said last mentioned aperture accommodating the respect-ive chains 7l. The respective plates 73 project through `the `apertures 77 for receiving the gibs 33 whereby -the head jamb is rigidly secured to the respective stiles of the sash. It will be noted that, the head rail 78 is provided with a depending Hange 81 co-acting with a molding or retaining strip 82 for clamping the glass in place. It will be noted that the flange 8l is arranged interiorly sothat the glass is always placed in position `from the interior. The bottom sash is provided with a bottom rail 88 similar to rail 78 in all respects, except that it is slightly beveled at 84 so that it may fit tightly against the wall 2O as well as the lsill 18. The bottom rail 83 is secured to the stiles of the bottom sash in a similar manner as described in respect to the top rail of the top sash. Likewise the meeting rails 85 and 86 are secured to their respective Stiles in the same manner as the top and bottom rails.

From Figure 2 it will be noted that the meeting rail 85 is provided with an inclined flange 87 interlocking with the groovcd member 88 whereby a water-proof and thiefproof structure is provided. A filling or trimming channel iron 89 is arranged in the rail 86 while the channel iron 9() is arranged in the rail 85 which acts as a filling member and also as a molding for holding the glass in place. In connection with the flange 87 it will be noted that the same is adapted to press against the embossed section 91 of the parting rail 86 whereby a tight fit is produced and, consequently, the sashes cannot shake. It will be noted that there is provided an embossed portion 91" (Figure 2) on each of the parting rails at substantially the center thereof while the vscrew heads 56 are provided for the upper the' walls QO-and 21.

What I claim is -l. A double hung window, comprisin metal frame or casing, an upper sash s ingly mounted in said frame, a lower sash slidingly mounted in said frame, means carriedy by the frame near the upper end for pinching the top rail of the upper sash Whenin a closed position said means including a screw having va comparatively flat head with the edge of the head rounded, and a parting strip formed with a pressed out cam near the center for preventingfrattling of vthe lower sash when in a closed position.

2. In a double hung metallic window, a metallic frame comprising a sill, a pair of side jambs connected with said sill, a head jamb overlapping the upper ends of said MLv side jambs, and an angle fitting or knee rigidly secured to the under face of each end of said head jamb and tol the upper end of each of said side jambs said fitting extending across said head jamb with a projection extending downwardly into -one of said side jambs.

3. In a double hung window, a metallic frame, said frame being provided with a head jamb, a sill and side jambs secured to the-head jamb and sill respectively, each of said side jambs being provided with a removable section near the bottom, 'a parting strip formed with a removable section extending across the first mentioned removable section, and a guiding molding overlapping the first mentioned removable section.

4. In a metallic double rhung window, a metallic sash provided With top and bottom rails,I each of said rails having apertures therein, a pair of stiles connecting said rails, said stiles at thev lower end-beingvprovided with tongues projecting through the apertures in the lower rail, chain engaging ybrackets secured to the stiles near the upper 6.
