Specification of Letters Patent.

Application filed. January 12, 1916. Serial No. 71,625.

To all whom it may concern:

Be it known that I, EUGENE F. (1001;, a citizen of the United States, residing in the city of St. Louis and State ofMissouri, have invented new and useful Improvements in Coiled Metal Weather-Stripping, of which i the following is a specification;

This invention relates to a coil of weather strip as an article of manufacture, and to the method of producing the same.

The invention relates to that type of metal weather strip in which the longitudinal edges of the strip are bent at an angle and also folded over and pressed fiat to provide a rounded edge. Prior to my invention it has been customary to-deliver these strips to the consunier'in straight lengths, as it had been found impossible to coil the same with-- out causing the strip to buckle, so that when applied in position on the door'or window frame it would not present a perfectly flat,

evensurface for engagement with the edge of thedoor or window. The necessity of delivering these strips in straight lengths,

has been the cause of great waste, as a portion of the strip must invariably be out off in-fitting it to door and window sashes of difl'erent sizes or heights, and the cut-off part is generally too short to be of any use. To overcome the objection to coiling and to prevent the waste, incident to the use of metal weather strips furnished in straight lengths, I conceived the idea of rolling the strip in such manner that it. could be readily coiled, and of delivering the weather strip in coiled packages so that by the use of my invention it is now possible for the operator to remove from the coil just the length of strip desired and sever that length from the remaining part of the coil without wastany part thereof whatsoever.

The invention is illustrated in the accompanying drawing, in which-' Figure-'1 is a broken view partly in sec-, tion, and. partly inside elevation, illustrat ing the manner of rolling the weather strip Fig. 2 is a View in frontelevation, on an en-' larged scale, of the compression rollers shown in Fig. 1 with the strip between them F 3 is a View in front elevation of,

. the bending roller shown in Fig. l; and Fig.

. Referring now to the drawing, the nuof the shaft 4 so that the meeting line of the two rollers will be slightly below a horizontal plane tangent to the circumference of the roller 2 at the upper-side thereof.

The numera15 indicates an arm which is pivotally mounted on a bearing 6 provided on a support 7 and which has rotatably mounted on its outer end a bending roller 8. The under side of this roller is normally at a considerable distance below the upper side of the roller 2, and this distance can be ad usted, and when adjusted maintained, by a set screw 9 working through a support 10 carrying a binding nut 11.

As ordinarily practised the strip 12 is first acted upon by a-pair of rollers to partly bend over its longitudinal edges, as indicated at 13 m Fig. 4,and to slightly bend the outer edge portions of the-strip in OPPO".

away, as indicated at 18, 19, to provide a. A

space to accommodate the bent-over end portlons 13 of the strip, the entire opposed surfaces of the rollers being parallel to each othenas shown.

In order toadopt the strip to form a roll I extendone side or face of the strip relativ'ely .to the other. For this purpose the rollers l and 2 are adjusted sufliciently close to each other to cause the endportions 13 'to be pressed against the angular portions 1d of the strip as it passes between the two rollers, and as these rollers are off center, the under circumferential edge portion of the upper roller being slightly below the upper circumferential edge-portion of the lower roller, the strip l2 i s' given a slight downward bend or curve as it passes be- It.

.fectly straight line.

BEST AVAILABLE COP.

tween the rollers, which is facilitated by the action of the roller 8, the position of which causes the strip to be turned downward so that as the strip is passed between the rollers l and 2 and under the said roller 8 it is caused to be bent around a portion of the periphery of the roller 2. The surface of the roller 8 is shaped to correspond to the shape of the rollers 1 and 2, having oppositely-disposed angular end portions 20, 21, and a conoidal central portion 22. The roller, however, is of much less diameter than the'snid rollers 1 and 2. This operation, as will be understood, causes a slight uniform compression or condensation of the material on the under side of the bent-over portion 13 of the strip, and a corresponding stretching, extension or expan sion of the material on the upper side of the angular end portions ll of said strip, and as this change occurs in a longitudinal direction in the strip, it results in imparting to the strip a natural tendency to coil, notwithstanding the angular bends in the strip. At the same time the bending or compressint; =ction upon the strip is so slight as not to event the strip when unwound and secured in position from extending in a per- As the strip passes from under the roller 8 it is immediately wound upon a reel, indicatedgenerally by 23, which may be operated in any suitable manner, either manually or by suitable driving mechanism, and when a coil of the desired size has been obtained by so winding the strip, the latter is cut and its free end secured in any desired manner to the reel toprevent it from unwinding. The strip thus coiled into a roll may be furnished to the user, who, as stated, will in practice remove from the coil just the length required in weather stripping an opening, and thus avoid waste. When the strip is unwound from the coil it will readily assume a practically straight position, and it will be found that the coiling has not caused it to buckle or to be permanently bent or distorted.

ll hile .l. have stated that the strip is curred in passing between the rollers 1 and 2, and under the roller S, this must be understood to refer largely to a temporary condition, the operation, in fact, resulting in putting the strip into a condition which will permit it to be coiled without buckling, or without causing the strip to be permanently bent or distorted rather than imparting a permanent curve to the strip.

I claim: l

1. As a new article of manufacture, a coil of metal weather stripping, the latter having folded longitudinal edge portions.

' 2. As a. new article of manufacture, a coil of metal weather stripping, the latter having ungularly-disposed and folded longitudinal edge portions.

3. As a new article of manufacture, a coil of metal weather stripping, the latter having folded longitudinal edge portions and being characterized by freedom from permanent bonds or distortions and from a tendency to buckle when unwound.

a. As a new article of manufacture, a coil of metal weather stripping, the latter having angularly-disposed and folded longitu dinul edge portions and being characterized by freedom from permanent bends and distortions and from a tendency to buckle when unwound.

5. As a new article of manufacture, a sup ply'roll of metal weather stripping consisting of a continuous strip having longitudinal edge portions folded against the body of the strip, the material ofsaid strip on one side being extended relatively to the other side of the strip to enable the strip to assume an arcuate form.

6. As a new article of manufacture, a metal weather strip consisting of a continuous strip having longitudinal edge portions folded against the body of the strip and conditioned to enabi'e the strip to assume an ,arcuate fornzwhen coiled into a supply roll.

In testimony whereof. I have hereunto set my hand.
