COMBINED PARTING AND WEATHER STBIK.

Application filed October 14, 1326. Serial No. 141,535.

This invention relates to a combined parting and weather strip for use between the outer and inner sashes of windows, and has for its principal object to provide strips which may be conveniently and economically produced of sheet metal, and will be so connected with the sashes that it will operate to advantage as a weather strip and will prevent shaking or vibration of the sashes from effects of winds or airfdrafts.

The invention includes an elongated, metallic sheet bent transversely to provide a hollow body to be interposed between the vertical parts and upper horizontal parts of the sash, saidmetallic sheet also being bent to provide recesses for receiving certain guidestrips carried by the movable sashes, whereby dust and air drafts will be ex eluded, and undue vibration prevented.

The novel and useful features of the invention are fully described and claimed herein, and are illustratedby accompanying drawings, wherein Fig. 1 is a horizontal section on line 1-l of Fig. 6. Fig. 2 is a vertical section on line 22 of Fig, 6. Fig. 3 is a perspective view showing one of the guide-strips for a sash. Fig. 4 is a perspective view showing a part of a metallic sheet bent transversely to provide parts of the device. Fig. 5 is a perspective view showing a part of a guide-strip, and Fig. 6 is a view of a window and frame in side elevation.

Referring now to the drawings for a more particular description, the invention. is

shown and described inconnection with conventional parts of a window frame, such as the vertical pulley stile 7,, the sash-stops 8 for the movable, outer sash 9, and inner, movable sash 10, also inconnection with the horizontal heacbpiece 11 for the upper part of the frame.

In order that the objects first mentioned may be attained, the device, in' part, consists of an elongated, metallic sheet bent transversely upon itself adjacent to its longitudinal edges to provide a pair of bearingmembers 12 and 13 and a pair of reinforcing parts 14 disposed approximately parallel with the bearing-members, and bent from the parts 14 at approximately right-angles to form a pair of brace-members 15, the middle part of said sheet being bent outwardly from the brace-members 15 to form a hollow body 16 and a pair of recesses 17 disposed at the sides of said body, approximately parallel with and opening at the edges of said beai'ingineinbers.

The hollow body is preferably of rectangular form in cross-section, its particular form; however, not being important except that it provides walls for the recesses 17 which are provided with, approximately, parallel walls. Numeral 18 indicates a sleeve which is disposed betweenthe outer wall of the hollow body and the frame-member or pulley-stile 7; and at 19 is indicated a screw or keeper which traverses the outer wall of the hollow body 16 and the sleeve and engages the frame 7, and it will be understood that any suitable number of sleeves and keepers may be used for securing the device to the frame-memberl, between the sashes. p

NumeralsQO indicate a pair 0 guidestrips, each being secured to the side of a sash and having awing a engaging in a recess 17. While broken away parts are shown in the drawing it will be understood that the length of the guide-strips correspond to the length of t-hesashes, the length of each combined parting and weather strip being equal to the length of the pulley-stiles or frames 7. r i

As thus described the bearing- members 12 and 13 are reinforced by members 14, this being of advantage for resisting stresses di- 'rected thereto by the sashes which may slide upwardly or downwardly in engagement with said members 12 and 13; r

The brace-members 15 operate to resist stresseswhen directed thereto by the keepers or screws, and the sleeves 18 prevent bend-c ing or buckling of the hollow body 16 when the screws or keepers 19 are secured to the pulley-stile or frame, and in operation, the,

device prevents movements of air currents to advantage, and since the guide-strips carried by the window sashes engage in the recesses undue vibration of the windows is prevented.

Having described construction and operation relating to the vertically disposed parts of a window, a particular description of the upper, horizontal, parts will not be required. The device is secured to the up tor the reason thatthe outer sash 9 when moved upwardly normally remains in engagementwith the head-piece and no proteetion against wind, weather or vibration is needed for the inner sash at the upper part of the frame since it is never or very rarelyraised upwardly to the head-piece.

As best shown in Fig. 2 of the drawings, the parts include an elongated, metallic sheetbent transversely to provide a bearing-member 12' and areintoreing-me1nber 14', a brace-member 15, a hollow body 16 and a recess 17, the latter being arranged for receiving the wing a of a guide-strip 20' which is seeuredto the horizontal parts of thesash 9, and on account of the construc tion as described the parts operate to exclude air currents and prevent undue vibration.

By referring to Figs. 1 andfl of the draw} ings it will be seen that the sashes are provided with grooves 31 whieh extend longitudinally thereof, the guide-strips being providedwith ridges c which engage in said grooves, this feature being 01'' advantage tor reinforcing said guide-strips so that their wings a will normally bear upon the r'einforcing-members for effectively excluding air currents. j i

lVh'ile I have shown and described specific construction, I do not Wish to be understood as limiting myself in this respect, and changes in form, size, proportion of parts; and minor details may 'be made as found to be of advantage, without departing from the spirit of the invention, said changes to bedeterrnined by the scope of the invention as claimed. j r j r I claim asmy invention,--- 1. A combined parting and weather strip forapplication to window frames and the sashes thereof, comprising a parting strip portion composed of a sheet metal strip bent on a longitudinal line to provide an intermediate channel-shaped body for attachment to a window frame betweenthe sashes thereof and with the open end against the frame, an outer portion of the strip being returned in spaced substantially parallel relation to the outer side of the body to provide a channel at the side thereof and returned abruptly against thevouter side of the channel and extending beyond the same to provide a fiat bearing surface for the adjacent sash and an anchoring and sealing projection for seating in the \\*i11(l(1f121111@, and a guide strip composed oi sheet metal having flat edge portions offset from one unotheand with the intermediate portion of the strip dis posed at substantially right angles to the edge portions, the outer edge of the intermediate portion projecting beyond the plane of the outer offset edge portion of the strip and returned upon itself? to provide an anchoring and sealing rib adapted to be seated in the side of the adjacent sash, the inner offset portion of the strip adapted for slid ing engagement in said channel oi the parting strip portion.

2. A combined parting and weather strip for applicationto window frames and the sashes thereof, comprising a parting strip portion composed of a sheet metal strip bent on longitudinal lines to provide an inter mediate channel-shaped body for attaeih ment to a window frame between the sashes thereof with the open end against the tralue, the outer portions of the strip being returned in spaced parallel relation to the outer sides of the body to providechannels at the sides thereof and returned abruptly against the outer sides of the channels and extending beyond the same to provide fiat bearing surfaces for the sashes and anchoring and sealing projections for seating in the window frame, and guide strips for attaelnnentio theinner sides of the sashes and each comprising a sheet metal strip having flat edge
