WEATHER-STRIP.

Specification of Letters Patent.

Patented Nov. 25, 1919.

Application filed February 20, 1919. Serial No. 278,311.

To all whom it may concern:

Be it known that I, FREDRICK ANDREW SoHA'rz, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in VVeather-Strips, of which the following is a specification.

One object of my invention is to provide an improved weather-strip which will. be particularly well adapted for use in connection with windows for keeping the sash tight so as to prevent air from passing between the sash and the frame, and also for preventing rattling of the sash.

Another object is to so construct my im proved weather-strip that. it will have a part resiliently pressing upon the sash when the sash is closed and will also include parts which will serve to move said resiliently pressed part out of engagement with the sash during the initial opening movement of the sash; thereby removing all friction between the resilient pressed part and the sash during the continued opening movement of the sash.

A further object is to make my improved weather-strip of a strong and durable construction and so that the parts thereof can be easily and quickly manufactured and assembled.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in Which-9- v Figure 1 is a front elevation of my invention illustrating its relation to a window sash when the sash is in its closed position,

Fig. 2 is a View of similar nature to that shown in Fig. l'illustrating the parts as they appear when the sash has been slightly raised to release friction of the weather strip upon the'sash, I

Fig. 4 is a transverse section taken on the line 4:4 of Fig. 1,

Fig. 5 is a transverse section taken on the line 55 of Fig. 2, r

Fig. 6 is a sectional elevationcf my im proved weather-strip and taken on the line 6- 6 of Fig. 4, and

Fig. 7 is a fragmentary perspective view of certain of the parts of my invention.

Referring-to the drawings, 8 represents a window frame having a sash 9 slidable vertically therein.

'My invention includes a channel-shape casing 10 which is preferably made of pressed sheet metal; one side portion 11 being of greater width than the other side portion 12 so a to provide an extension 13 adapted to receive screws 14 for attachment to the frame 8. The top and bottom ends 15 and 16 of the casing 10 are closed and extend at right angles to the

side portions

11 and 12 and their connecting portion 17.

An elongated channel-shape shoe 18 has its

side portions

19 and 20. adapted to slide between the

side portions

11 and 12 of the casing 10. The portion 21 of the shoe 18 between the

side portions

19 and 20 extends the full length of the shoe as clearly shown wise secured to the inner surface of the portion 21. The bracket 24 has a portion 27 which extends parallel with and directly adjacent the side portion 12 of the casing 10. The portion 27 of the bracket 24 has a transversely extending slot 28 therein and through this slot and also through holes 29 in the-portions 11 and l2-of the casing 10 is adapted to extend a screw 30. The end 31 of the screw 30 is designed to enter the frame 8 and assist in securing the weather strip to the frame as clearly shown in Fig. 4. The screw 30 has an enlarged portion 32 which provides a shoulder 33 which is adapted to abut the outer surface of the vside portion 12 of the casing 10; it being noted that the holes '28 in said

side ortions

11 and 12 are of less diameter t an the width of the slot 28. the shoulder will ab'ut theouter side surface of the portion 12 and limit the inwardvmovement of the screw30. The side portions 19 and 20' of the shoe 18 have notches 34 which straddle the screw and other screws 35 which also 7 extend through the casing 10 and serve as additional securing means for said casing to,

the frame 8.

.By the above construction it wilhbe inn derstood that the shoe 18 is free to SllClG'll'liJO and out 01" the casing 10. I interpose resiliidentical parts it is only necessary. to de-' scribe one of the units and it will be understood that the other unit includes similar elements serving inthe ame capacity. Each unit includes a b owed spring 38 having lugs 39th'erein. The end portion 40 of the bowed spring 38 is adapted to engage the inner surface of the portion 21 of the shoe 18. The intermediate portion 41 is secured to a strip 42.by a bolt 43, said bolt also passing through the portion 1 7 of the casing 10. The opposite end portions of the strip 48 having lugs 43 thereon which are respectively in alinement With the'lugs 40. The

lugs

40 and 43 provide positioning means for two coiled cushion springs 44' By this arrangement the springs '38 and 44 serve to move the part 21 ofthe shoe 18 into 'fricional engagement with the sash 9. The part of the screw 30 between :the

shoulder 33 and the head, 45 forms a pivot support fora latch 46. The latch 46 has two arms 47 and 4-8 and a cam portion 4-9 as clearly shown in Figs. 1 and 2. An actuating finger 50 is secured to the sash 9 and when the sash is in its closed position as shown in Fig. 1 the finger 50 is positioned between

flanges

51 and 52 on the arms-47 and'48 respectively. Also as shown'in Fig. 1, the low part of the cam 49 is in engagement with a lip 53 which projects forward from the bracket 24. When the sash 9 is raised the finger 50 engages the flange 51 pivot and atthe same time causesthe high portion of the cam 49 to engage the lip 53 of the bracket'24 and cause the shoe 18 to be moved out of engagement with the sash 9;; this movement taking place against the the distance necessary to completely-open it.

l/Vhen the sash is again lowered the finger will engage the flange 52 ofthe arm 4-8 and thereby swing the latch on its pivot} and move the high portion of the cam 49 "prevent rattling of the sash and at the same time it will form a seal to prevent air from I passing between it and thesash.

By making the resilient pressing means in units as above described they can be quickly assembled and positioned and the same bolts which serve to hold the strips 42 to the springs 38 also serve to secure the units to the ca sing 10.

To remove the shoe 18 from the casing 10 it is merely necessary to remove the singlescrew 80 after which the entire shoe can he slid from the casing to permit access to the interior thereof. It will be further noted that the casing 10 and shoe '18 pro vide guiding means for the sash 9 and that they take the place oft-he usual. side .rail orstile which is provided on window frames While Ihave described my invention taking a particular "form, it will be understood that the various parts of my invention may be changedwithout departing from the 'spirit'thereof, and hence I do not limit myself to the precise construction set forth, but

consider that I am at liberty to make such 7 7 changes and alterations as fairly come within the scope jot-the appended claims.
