METAL WEATHER-STRIP.

Specification of Letters Patent.

Patented Aug. 15,1914.

Application filed April 3 1915.- Serial No. 18,871.

To all'wkom it may concern:

Be it known that I, CHARLES A. Srroennn,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Im-' provements in Metal Weather-Strips, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, part of this specification.

My invention relates to improvements in metal weather strips.

The object of my invention, generally speaking, is to provide a weather strip of such improved construction that it may be more readily installed than those heretofore found to be effective, and one which at the same time, shall effectively carry out the purpose for which it is intended. As

contributory toward this general object, my invention has as other objects, to provide as part of a complete weather strip, a parting bead which may be substituted bodily for the usual parting bead found in wooden window frames; to provide a projecting hollow parting strip between the window sashes within which slide metal extensions carried by the sashes; to provide a weather strip located between the sashes, and of such configuration as to limit the play of the sash in certain directions, although permitting a reasonable amount of movement. in other directions; to provide a parting strip which is neat and ornamental; to; provide a weather strip which may be installed without cutting away or changing the sashes in any Way; and to provide a weather strip which, while effective in shutting off leakage of air, nevertheless permits free sliding movement of the sashes.

Other objects will be apparent without specific enumeration thereof.

In the accompanying drawings, I have illustrated several embodiments of the invention. I do not limit myself to these particular embodiments, but consider that they typify the main features of the invention.

Figure 1 is a section on an enlarged scale taken on a horizontal plane through one side of the window frame and sashes. Fig. 23is a partial front elevation of a window frame and its sashes. Fig. 3 is a sectional elevation of a modified form of weather strip. Fig. 4: is a section on a horizontal plane taken through a complete window" forming a which .is substantially apparent.

ing strip a of rectangular"cross-section, as

shown in Fig. 4. The parting strip fits within a groove in the sash and projects sufiiciently to provide guides against which the sashes slide. The latter are further confilled by the usual stops 5 and 6.

While my improved weather strip may be installed very conveniently in new sashes at the time they are made, it is particularly valuable in that it may be applied to windows already in use. It consists in one form, as shown in Figs. 1 and 5, of a special parting strip 7 of wood about half of which is adapted to fit within the groove which receives the usual parting strip previously mentioned, said usual parting strip being readily torn out or pulled out, thus permitnon-rusting metals such as copper or zinc, or any suitable ornamental and reinforc-v ing material. Said metal is applied by being rolled onto the wooden form, the long edges thereof 9, 10 being rolled into the wood to grip the latter firmly. The parting strip is provided with a central slot into which the middle element of a metal structure,

T shaped in cross section, is inserted. Said T structure, in the form illustrated, consists of two substantially U shaped strips or channels 11, although the parallel flanges thereof are of unequal length. It need not necessarily be of two part construction however, as will be To positively lock it in place, said metal element may be held by small nails 12 driven through the reinforcing metal and through the wood of the parting strip. The part of the T construction which projects from the wood forms in substance a hollow metal parting strip, in that the portion of the parting strip visible to the eye appears to be made entirely of metal and is hollow, being divided by a central partition into two chambers or recesses shut off from each other as far as circulation of air is concerned.

Metal strips in the form of Z bars 13, are

secured to each of the sashes. and project i'nto the respective recesses just mentioned.

Said ,2 bars are held tof lie sashes;by.

small nails or screws 142M111 orderlto, apply them, it is necessary merely-t0 remove the.

inner stop"6 and the original parting strip, whereupon the sashes may be lifted out of the frame after disconnecting the sash cords. The fzIbaIS 13 may-then be nailed thereto.

There isalways sufiicient clearance 15 'be.-'

tween the sash and the wooden frame topermit the additional thickness of 'met'al without causing any binding of the sash as it slides. .In fact, there isusually toomuch play particularly. after the building has j been 1n use for a year or more, so that by tally in the plane of the sash is permitted, f however, for example, about a quarter of increasingthe effective width of the sashes, by the introduction of two thicknesses of f metal, an'advantage is obtained. The metal used for the Z bars 13 is preferably zinc, although other metal may .be employed. I

It will be noted that the Z bars 13. are made by bending so as to form three sec tions. The middle section isparallel to and closely confined between the adjacent metal walls provided by the strips 8 ..,and 11.

There is enoughclearance to permit free. sliding of the sashes, but the latter are positively locked against any appreciable back; and forth movement such as usuallycauses'j rattling. Considerable free play horizonan inch being availablejn the usual constructions. This will be readily understood from an inspection of Figs. 1 and 5, in .whichth'e clearances are somewhat exaggerated. Furthermore, it will benoticcd that the short flanges of the channel members 11 are substantially in the plane of-the sides of f the parting strip where the latter is of its greatest width; in other words, the part that fits within the groove. Battling of, the sashes is therefore further prevented because of the fact that the sashes bear against said short flanges.

The parting strip" extends the entire height of the window frame, and to permit of its convenient insertion, is'made 1n two equal sections as shown in Fig. 2. After the 2 bars 13 have been nailed to the sashes and the latter replaced in the frames,

" the two sections of the parting strip are mstalled, one at a time, the lower one being installed while both sashes are raised as far as possible, and the upper one being installed while the sashes .are lowered as far I as possible.

ployed commercially, it has been necessary In a few weather strips heretofore emto do considerable carpenter work on the sashes for example, either to cut aigroove" in the outer sides thereof, or'to cut away a corner. This feature has made such weather strips very expensive; Other prior weather strips bear witha yielding pressure on the' sashes de ending on friction to maintain-an air tight oint.- Such devices, aslong as they areeifective for the urpose, create so much friction that it is di cult to raise-and lower the sashes. I am further aware that it has been'pro'posed heretofore to provide weather strip'svin' connection with the parting head,

but such'devices as have been tried out here tofore, are either open to some of the objections just noted, or elseiare unsightly. It will be recalled that one-half of the parting head" is always visible. For this reason, the

matter of appearances has considerable bear-- ingon the marketability of. 'weather'strips.

In my construction the appearance of the parting head is unusually attractive, more so that the standardjwoodenparting head for which it' is substituted. Furthermore, it u has the'general appearance ,of a rectangle and accordingly-conforms in general outline to what is usually seen and is not ofsuch peculiar construction as to attract unnecessary attention; It is therefore particularly stripis the same as the one previously described. The parting strip at the right hand side of Fig. 4 as previously stated, isthe old style wooden one before being pulled out,

the two being shown in this figure to emphasize the general similarity in external appearance and the ease with which one'may' be substituted for the other.

i In Fig. 3, I have shown a further form of weather strip inwhich the entire, parting bead is made of metal. It 'i'sformed-ofan outer-shell 17 which receives channel memhere 18 similar to those previously described except that the lower ends may be bent outwardly at '19 to lock said channels in. place.

The 2 bars which are carried by'the sashes. and cotiperate therewith, are the same as those previously described.

. It will be obvious that various changes may be made in the structural details described wherby ,various forms other than those illustrated herein will result. I de- \E l-l,e therefore, to cover" in the appended claims whatever modifications fall within the scope of the invention.

Having thus described my invention what I claim as new and 'desire to secure by Letters Patent of the United States is:

1. A parting bead consisting of a wooden strip having a slot therein, a T-shaped sheet metal strip comprising a web anda top con sisting of two outer flanges, the web being seated in said slot and the extremities of the top or outer flanges being bent back so that the web and each top or outer flange and its corresponding rebent extremity forms a channel.

'2. A parting bead consisting of a supporting element, a web secured thereto and rojecting therefrom, and oppositely exten ing flanges at the extremity of said web, said flanges being bent toward said supporting element, so as to form with said web apair of parallel inclosures.

3. Sheet metal weather stripping comprising sheet metal channels carried by the parting bead and sheet metal Z bars carried by the-sashes, said-Z bars fitting between parallel portions of said channels and parting bead and closely confined therein without binding whereby movement of the sashes backward and forward is limited, but free play sidewise as well as up and down sliding movement is permitted.

4. A parting bead consisting of a wooden strip having a slot therein and a pair of sheet metal channels each having a flangese-- cured within said slot.

5. A parting strip comprising a body portion arranged to fit within the usual window sash groove, an extension of reduced width and a pair of sheet metal channels secured each by one flange Within a central slot insaid parting strip and having the other flange substantially in the plane of the sides of said parting strip.

6. The combination with a window frame having a slot ,therein on each side between the sashes, of a partingstrip fitting within each slot, each parting strip being made in two independent sections having hollow alined portions, and means carried by said sashes extending into said hollow portions and interlocking with said parting strip whereby they cannot be inserted or with-- drawn therefrom except at the ends of said sections and upon the removal of the upper 8. A parting bead consisting of a wooden strip having its sides reinforced with sheet metal and having a central slot, a pair of channels received, each with one flange within said slot and nails passing through said reinforcing strips and through said flanges, said strips having their edges forced into the wood to grip the latter.

9. The combination with a window frame, sashes,- and aparting strip between said sashes, of sheet metal channels each having one flange received within a slot in the middle -'of said parting strip, and a 2 bar secured to each sash and projecting into the space between the parallel flanges of each channel, the outermost section of each 2 bar being parallel to the adjacent base of the corresponding channel and adapted to move toward" and away from said base as the sash moves sidewise, said section nearly filling the space between said parallel flanges to aid in preventing rattling and to cut off leakage of air.

In witness whereof, I have hereunto subscribed my name in the presence of two wit- IIGSSBS.
