My invention belongsto that general class of devices known as weather strips for use on doors, windows, or the like, for prevent-. ing the admission of cold air, dust, dirt or the like, through or past the window or door. The invention has among its objects the production .of a device of the kind described that is simple, convenient, durable, reliable, eificient and satisfactory for use wherever found applicable. It has among its further objects the production of a weather strip that may be economically manufactured and conveniently and economically installed. Many other objects and advantages of the construction herein shown and described will 7 be obvious to those skilled in the art from frame.

the disclosures herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts:

Fig. 1 is a view in elevation of a door to which the weather stripping is applied;

Fig. 2 is a sectional view taken substan-' tially on line 3-3 of Fig. 1, the door open;

Fig. 3 is a. sectional view taken on line 3-3 of Fig. 1 with the door closed;

Fig. 4 is a perspective view of the type of device illustrated in Figs. 2 and 3;

Fig. 5 is a sectional view taken substantially on line 5-5 of Fig. 1 with the door closed;

Fig. 6 is a similar view showing the door open;

Fig. 7 is a perspective view of the weather stripping shown in Figs. 5 and 6; Fig. 8 is a sectional view through a portion of a window and window frame illustrating the weather stripping applied to the window; v

Fig. 9 is a perspective view of the weather stripping shown in Fig. 8; and

Fig. 10 is a perspective view pf a simplified form of weather strip.

Referring to the drawings in which only the preferred embodiments of the invention are shown, 1 represents a door of'suitable construction hin ed as at 22 to thedoor frame at the sid e 3. Weather stripping is applied tothe side 3 of the doorframe and also at the side 4 and at the top 4' of the I will first described the weather stri pin applied at the frame at the free edge 0 the door and at the top. Referring particularly to Figs. 2, 3 and 4:, 4 represents the frame and 5 the usual door stop extending around the frame and against which the door seats when closed. This may be secured in place by nails or screws 7 or the equivalent, arranged to pass through apertures 8 in the strip 6, preferably of a metal that has spring or resiliency. As shown, the metal strip '6 is seated between the stop 5 and the frame, with the edge extending out and thence bent substantially at right angles, as indicated at 9, with the free edge bent over as indicated at 1 0. The metal having resiliency tends to spring out as indicated in Fig. 2. When the door is shut, however, as shown in Fig. 3, the strip 6 seals the door about the free edge and top, preventing the admission of dust, dirt and cold air. The weather stripping at the back edge or hinged side of the door I prefer to slightly modify in construction, as shown in Figs- 5 to 7, in which 15 representsa strip of metal of some resiliency having the one edge preferably bent over upon itself as indicated at '16 so as to reinforce and stiffen the strip. ,It may be provided with holes or openings 17 through which nails or screws pass to secure the same in place. The opposite edge of the strip is bent over and of a width to form the wing portion 14, and

- thence bent back as indicated at 18, with the extreme edge bent back again and outwardly as indicated at 19, as shown. The same is secured in place b suitable fastening means 20 adjacent the a utting door-edge. When the door is open, as shown in Fig. 6, the weather stripping tends to expand or spring outwardly, the same being embraced by the door as shown in Fig. 5 when the door is shut. This forms a tight and effective seal similar to the stripping at the opposite edge of the-door so that the door is sealed completely about the same at the two sides, edges and top. i

Referring to Figs. 8 and 9, I have shown a similar weather stripping adapted to be placed on the windows etween the stops and 'on the frame. Referring to Fi .8, 24 re resents the window'frame, 25 an 26 the si e stops and 27 the center or parting stop. These stops maintain the window sash frames in position and in'their desired relative-positions. The weather stripping is arranged between the frame and the sash edge,

and as shown, consists of a plate 30 having a portion turned over and bent back as indicated at 31 so as to reinforce and stiffen the edge. The same is provided with openings or holes- 32 preferably in the reinforced edge through which securing means such as nails or screws may be passed to secure the weather stripping in place. The opposite edge of the strip is turned over and extends back toward the reinforced edge as shown at 33, with the extreme edge bent over and turned back the opposite direction as indicated at 34. These strips are secured in place substantially as shown in Fi 8 by the fastening means 35 or the equiva ent. Generally I prefer to provide the weather stripping at both sides of the frame above the outer sash and at the bottom on the sill adjacent the lower sash so that when the sashes are closed, the Window is completely sealed up.

In Fig. 10 I have illustrated the simplified construction, in which plates 37 are provided with the holes 38 for fastening means and with an extending portion 39 preferably slightly turned back at the free edge as indicated at 40. This construction may be installed similar to the stripping shown in Fig. 8, and likewise may be installed on the door frame as desired. This type is particularly adapted for closing the joint between the two sash at the center of the window.

Generally I prefer to pinch or bring the adjacent face portions of the metal together at the fronts as indicated at 41 in the several figures. The strip may then be folded more or less fiat, when required, without danger of causing a set or any binding. Same, when so constructed, more effectively seals the space and the full resiliency of the metal is secured.

It will be noted that with all of the con 'structions, thedoors or windows when closed tions may be made in the same without de parting from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

A weather strip comprising an integral metal strip having a longitudinal base por-' tion, an intermediate portion extending from said base and forming a sharp angle therewith, the free end of said intermediate portion bent sharply'upon itself outwardly and backwardly forming a narrow portion of double thickness, and an arcuately formed outer portion extending from said portion of double thickness, the free end of said outer arcuate portion stopping short adjacent said sharp angle of said base and intermediate portions.

In testimony whereof, I have hereunto signed my name.

WILLIAM J DENNIS.
