METAL WEATHER STRIP.

Application filed March 5, 1923. Serial No. 622,713.

This invention relates in general to metal weather stripping, and has more particular reference to metal weather stripping provided upon the sash and parting strips of the window. I

A principal object of the present inven tion is the provision of a weather strip of greater and more prolonged eflicienoy than those heretofore in use and which may be cheaply manufactured and readily installed.

One of the objects of my invention resides in providing an improved construction over that shown in patent to Charles A. Shogren, No; 1,195,108, of August 15, 1916, which patent discloses a complete weather strip including a parting bead which may be substituted bodily for the usual parting bead found in wooden window frames, andwhich parting bead includes a weather stripping portion adapted to co-operate with a complementary strip or strips fastened to he window sash whereby the space between the sash and the parting strip is effectively sealed.

One of the objects of my improved construction over that shown in the afore-mentioned pate-ntresides in providing an arrangement for more easily attaching the weather strip to the face of this parting strip, and for also removably fastening the parting strip with its weather strip into the usual channel of the window casing or frame whereby it can be quickly removedfor repair or assemble ofmy improved strip to the window sash. I

Still a further object of my improved invention resides in my improved parting strip having recessed shoulders on that portion which projects from the window casing, a novel. arrangement of sheet metal weather stripping attached to the front face of the stripping and extendingover and around the sides of the parting strip to provide lateral flanges arrange in spaced apart arrangement from the outer walls of said shouldered recess so as to receive in such spaced portions, complementary angle strips fastened to the window sashes.

Yet another object of my invention resides in providing such complementary angle strips attached to the window sashes with outer hemmed or folded edges which lie within the flanged portions of the strip at tached to the parting strip, which hemmed edges not only provide tight contact with the lateral flanges but also eliminate any scraping action. 7

A further object of my invention is the provision of a weather stripping of this character, which, while requiring a minimum amount of metal, will possess improved protection against circulation of air through the window.

Numerous other objects and advantages of the invention will be apparent as it is etter understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawings,

Figure 1 is a partial perspective showing weather stripping embodying my present invention installed in place; and

Fig. 2 is a horizontal section on an enlarged scale through the same.

For the purpose of illustrating my invention I have shown on the drawing a portion of a. window casing or frame, indicated generally by reference character 11 and particular description of which is unnecessary to an understanding of my present invention. It should, however, perhaps be stated that this casing is provided with the usual parting strip receiving channels or recesses 12 and, in the present instance, rails 13 provide for the sliding of two window sashes 1 1.

My improved weather strip comprises a combined parting strip and sheet metal stripping attached thereto and adapted to co-operate with complementary sheet metal stripping attached to the window sashes As clearly shown in Figure 2, the parting strip 15, which is adapted to replace the original parting strip in the window, has its sides cut away slightly throughout its length and from the casing or frame'proper outwardly to provide recessed shoulders. The outer face of the parting strip is recessed, and in the present disclosed form of my invention, this recess consists of a channel or groove 17.

The weather stripping pro-per in the present preferred form of the invention,

comprises a metal strip seated in the recess or groove and having parts extending in the form of flanges along the sides of the part ing strip in co-operative overl- Jed rel on with angle strips secured to the edges of "he sash and extending between the flanges mentioned and the parting strip itself. illeteronce character 18 indicates a. central. strip depressed throughout its lingth at 19 to extend into the channel 17, the portions of the strip adjacent said channel engaging or resting against the outer face of the parting strip. The metal of this central strip extends out beyond the side taces of the parting strip and 's bent inwardly to form two flanges 21. Fastening means are providd within the groove or channel 17 and these means in the present instance consistof nails or brads 22 which are driven home through the portion of the weather strip arranged in the channel or groove 17, entering into the wood thereof with the heads engaging the material of the strip adjacent the outer edge of the recess and with the points cleated or clinched behind the strip.

(lo-operating wez'ither strips of angle form are indicated by reference character Ono leg of this angle is secured against the side edge or face of the sash by screws 236 or otherwise, with the angle arranged toward the parting strip. The free edge of this leg is reinforced, convenient form of reinforcement being to fold the material back upon itself as indicated at 27.

'lhus constructed both co-operating menihers of each pair of flange parts arr-ang ed lfctween the s: sh and parting strip are reinforced. the flange part ssociated with the windo. sash by the return told 527 and the. flange part tiSSOClUiIGtl with the parting strip by close l'irin contact with its outer face.

The hennned or folded edge 27 of ea -h angle strip in addition to haring t functionof forming a tight lit with t lateral ilaii Q1 of the strip attached to the parting strip, also provides a means for limiting the outward increment of the angle strips attached to the sashes. llxperience has shown that when an installation his been in use considerable time. there is a pronouncee shrinkage of the saihes in the window frames. In other rords. referring to Fig. 2, the sashes Ll. shrink away from the frame 11. thus moving outwardly from this frame in a direction toward the h ttoin of the drawing as shown in Fig. 2. This shrinking inovenent will be limited by the hemmed edges 27 of the angle strips abutting the. i'iolded flanges .21. and since these edges are heinnied there will he no scraping action as there would he if the edges were raw.

It will he noted that the metal stripping other leg of the secured together ii interlocked relation. The arrangement 111st described insures ag lust deformation of the flange parts and the Stdjitl'it'tlOll of the n'ietal strip from the wood.

The parting strip is preferably secured in place by screws 28, which screws are shown in dotted lines in Figures 1 and 2 of the specification, taking through the metal strippii'ig 18. the lCCQHS or groove 17 and on through the parting strip into the casing. the head 25) of the screw engaging the metal strip 18 OPPOb'll'G the presented faces of the parting strip along side the groove. These faces 1 ray be formed or shaped. if desired. on a sligl'it rounded bevel to more closely fol low the configuration of the strip 18 and. reliere any necessity for providing sharp folds.

it will he noted from Figures 1. and 2 of the drawings that the sheet metal stripping w i through the re-eiitraut fold of the stripoin 1' r-i it? as it nes 111 the channel or recess 17 and 1 n 7 u thence int.) the parting strip to. .hese nails or brads 522 are arran ed in s )aced relation 7 4 1 h V "l =tudmai or the strip. In addition. 111 irerreniue' s )aced relation longitudinal of m in i: he strip. the screws LS are fastened through he re-entrant fold of strip 18 as it lies in the channel or groove 17 of the parting strip thence through the parting strip and into the 'l'ranie ll. thereby detachably fastening ray combined unit weather stripping in place. it is thought that the invention and many of is attendant. advantages will be underr from the foregoing description, and it )e apparent that Ytll'lOllS changes may nude in the form. construction and arrangeinent of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely .1 preferred enilmdiineut thereof.
