PARTING STRIP Filed Nov. 3, 1954 INVENTOR.- CA RA 0 MA NC/N/ 1 I ATTORNEY,

Patented Oct. 29, 1935 UNITED STATES PATENT OFFICE PARTING STRIP Carlo Mancini, Stratford, Conn.

Application November 3, 1934, Serial No. 751,357 8 Claims. (01. 20-524) This invention relates to new and useful improvements in parting strips for window frames.

An object of the invention is to provide a parting strip of improved construction which will function to prevent rattle of sashes in a frame and which makes for a weather proof window construction and which is closed at its outer side.

Another object is to provide an improved window construction including the mentioned parting strip and means for securing it in place.

Other objects and advantages will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown. However, it will be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the appended claims.

In the drawing:

Fig. l is a perspective view showing a portion of a window construction incorporating the present invention;

Fig. 2 is a horizontal sectional view through an edge portion of the sashes and one side of the frame;

Fig. 3 is a perspective view of an upper comer portion of the lower sash;

Fig. 4 is a detail sectional view showing the means securing the lower portion of the parting strip in place.

Referring in detail to the drawing the window frame is generally designated I and vertically slidable in the frame are upper and lower sashes II and I2 which sashes are arranged between inside and outside beads I3 and I4 respectively. The frame I I] includes a ,head I5 with which we are not particularly concerned and a sill I6 and between the head and sill is a side jamb IT. The lower end of the side jamb I! is dadoed into the sill I6 as shown at I8a in Fig. 4 and opening through the inner face of the side jamb and extending from the lower end of the side jamb upwardly at least to the head I5 is a groove I8.

A parting strip I9 comprising an elongated body preferably formed of a single piece of sheet metal and substantially rectangular in transverse section is arranged with one side portion within the groove I8 and the parting strip extends from the sill I6 to'the head I5. One wall 20 of the parting strip is inwardly bowed as best shown in Fig. 2 and this wall is at the bottom of the groove I8. The side walls 2I and 22 of the strip extend outwardly through the open or front side of the groove I8 and the outer wall of the parting strip comprises inner and

outer wall sections

23 and 24 arranged in overlapping relationship as for a purpose to be described.

The upper sash II includes a lower or meeting rail 21, an upper rail 28 and a vertical side rail 29 while the lower sash I2 includes a lower rail 30, a meeting rail 3| and a vertical side rail 32. In the opposed faces of their

vertical rails

29 and 32, the upper and lower sashes are provided with vertically extending grooves 33 and 34 which grooves are of a size and so located as to accommodate the beads or ribs 25 and 26 on the sides of the parting strip I9. This is as best shown in Fig. 2. The meeting rail 21 of the up per sash has a laterally projecting portion 35 which portion projects inwardly or toward the inner sash while the meeting rail of the inner or lower sash I2 has a lateral portion or over-hanging portion 36 extending or projecting outwardly or toward the upper sash. When the sashes are in closed positions the

portions

35 and 36 inter-lock or abut to provide a weather tight joint. The projecting

portions

35 and 36 do not extend for the lengths of the meeting rails but have their ends cut away as at 31 in Fig. 3 and the shoulders 31 overlie the overlapping

wall sections

23 and 24 of the parting strip and maintain the outer wall section 24 against the inner wall section 23. With this construction and with the engagement of the sashes with the beads 25 and 26 of the parting strip the latter is held in place in the groove I8 and the wall section 24 of the parting strip is held against the wall section 23 so that said sections slide one on the other and the entrance 40 of dust or rain into the parting strip is prevented.

To prevent removal of the parting strip by person at the outer side of the house the lower end of the parting strip is held within the groove I8. This prevents the removal of the parting strip so as to permit of removal of a sash as might be attempted in an effort to burglarize the house. As shown an opening or hole 38 is provided in the sill I6 opening through the bottom of the dado I8a in line with the groove I8 in the side jamb IT. A pin 39 which may be a short section of a dowel rod or of metal or the like has its lower end inserted into the hole 38 and is of such length as to extend above the upper side of the sill I6 and its upper end is located in the groove I8. When the parting strip is being positioned the sashes are not in place and the lower end of the parting strip is telescoped over the upper end of the pin 39 and the size and location of the parts is such that the upper end portion of the pin engages the .60

rear wall 20 of the parting strip andmaintains said wall against the bottom wall of'the groove 18; It will be apparent that the pin 39 is concealed by the parting strip and that it will prevent outward movement of the lower end of the parting strip with respect to the groove [8.

It should now be understood that the parting strip I9 is secured in the groove l8 without the) use of screws or other means perforating the strip and that the strip is held in placeby engagement of its side walls 2| and 22 with the side walls of the groove, if the strip is permitted to expand to that extent, and that the strip is further held in place'by engagement with the sashes and particularly with the shoulders 31 at the ends of the-meeting rails of the sashes and that the lower portion of the strip is secured by the pin 39 engaging the rear wall of the strip. Since the v

forward wall sections

23 and 24 of the strip are 20 slidable by or on one another it will be understood that the strip is yielding or resilient and that its side walls 2| and 22 may yield toward and from one another so as to maintain their beads '25 and 26 in the grooves 33 and 34 in the vertical sash rails and that such being the case the parting strip has weather-tight engagement with the sashes and 'will also prevent the sashes from rattling in theframe. The overlapping wall sections 23'and 24 of the strip completely close its outer side and prevent the entrance of "dust or Having thusset forth the nature of my invention, what I claim is:
