WEATH ER-STRI P.

SPECIFICATION forming part of Letters Patent No. 596,091, dated December 28, 1897.

Application filed July 26,1897.

.of Connecticut, have invented certain new and useful Improvements in Weather-Strips 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. l

The object of my invention is to provide a weather-strip with means of an improved form for automatically raising and lowering the same, thereby simplifying the construction and lessening the cost of manufacture of the device. Y

To this end my invention consists in the weather-strip constructed and operating as hereinafter fully described, and particularly pointed out in the claim.

Referring to the drawings, in which like numerals designate like parts in the several views, Figure 1 is an inner side view of a Weather-strip embodying thev invention, the same being broken away at its center to reduce its length. Fig. 2 is an end view thereof. Fig. 3 is a partial longitudinalsection taken on the inclined line fr. Fig. 4 is a crosssection taken at line y y. Fig. 5 is a face view of the form of actuating-lug employed when such lug is placed at the outer or free side of the door-casing. Fig. 6 is a side view thereof. Fig. 7 is a face'view of the form of lug employed when the same is placed at the inner or hinge side of the door-casing. Fig. 8 is a side view thereof.

The numeral 1 designates the frame of the device, which frame is recessed at the bottom and at its inner side to receive the strip 2, as shown in Figs. 2 and 4, and is chambered at 3, above said recess, to receive the operating means for said strip and form a housing therefor.

The strip 2 is of the usual form and has the usual rubber or felt facing 4 projecting from its lower edge,as shown. Said strip is adapted for a limited vertical movement within the recess i-n the frame, and it is connected to the latter by two or more links or radius-bars 5, which-are pivotally connected at one end to the strip and at their opposite end to the frame,

as shown by broken lines in Fig. 1 and by full lines in Fig. 3. An operating-rod 6 is supported upon the frame above said strip in such manner as to be capable of a limited longitudinal movement, and a spring 7, engaging said rod at one vend, causes its opposite end to normally project beyond the end of the frame, as shown in Fig. 1. Two or more links S are pivotally connected at their lower end to the strip 2 and are similarly connected at their upper end to flattened portions of said rod 6, and the combined action of said links and the links or radius-bars 5 is such that when the rod 6 is moved toward the left, in Fig. 1, in opposition to the stress of spring 7, positive downward movement Will be imparted to the strip 2, as indicated by broken lines in Fig. 1, and When the rod is moved in the opposite direction the strip is positively moved upwardly.

To adapt the device for use on both right and left hand doors, I provide two forms of abutting means for automatically moving the rod 6 against the force of its spring when the door reaches its closed position. Then the door is so hung that, the frame 1 being secured to its outer side, the projecting end of rod 6 is at the outer or free edge thereof, I use the form of lug shown in Figs. 5 and 6, consisting of a base 9, having holes to admit the fastening-screws, and an arm 10, projecting from said base, the acting face 12 of which arm is curved, as shown in Fig. 6. Said lug is secured to the outer or free side of the doorcasing in such position that as the door is swung to its closed position the curved face 12 of its arm 10 will engage the projecting end of rod 6 and force the latter inwardly, thereby forcing the strip 2 downwardly against the door-sill and holding it in such position so long as the door remains closed. As soon as the end of rod 6 clears said lug, when the door begins its opening movement, spring '7 returns the rod to its normal position and positively moves the strip to its highest position.

When the door is so hung that the projecting end of rod 6 comes at the inner or hinged edge thereof, I use the form of lug shown in Figs. 7 and 8, the same consisting of a base 13, containing the holes for the attachingscrews, and a block 14, projecting from said base. This lug is secured to the hinge side of the door-casing in such position that as the door reaches its closed position the rod G will abut against the outer face of the block 14 and will be moved inwardly, thereby depressing the strip, the spring 7 restoring the parts to their normal position when the door opens, as before described.

The particular forni of operatingdng used is not material so long as it is adapted to produce the described result in the manner stated.

By the use of the links and radius-bars to communicate motion from the sliding rod to the weather-strip, as herein shown and described, I entirely obviate the use of pivoted levers for such purpose, which levers by reason of unequal expansion and contraction of the wood and from other causes are liable to bind and work hard and by reason of undue wear upon their pivots are liable to become loose and irregular in their action, so that they fail to keep the strip properly compressed upon the door-sill when the door is shut. The link movement devised by me, on the contrary, is sure and positive in its action under all circumstances, regardless of wear or unequal shrinkage of the wood parts.' Furthermore, by connecting the movable strip to the frame l in the manner herein described I avoid the necessity of providing guides for the strip in its movement, and thus prevent any possible binding action between the strip and such guides and insure free movement of the strip at all times, besides greatly simplifying and lessening the cost of construction of the device.

The frame l and its attached parts are quickly and conveniently fastened to the door by means of screws passing through the series of holes 15. (Shown in Fig. 1.)

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination with the frame l adapted to be secured to the side of a door, said frame being recessed and chambered as described and provided with bearings at its ends, of the rod supported in the bearings on said frame and adapted for longitudinal movement therein, spring 7 pressing said rod in one direction and causing one end thereof to normally project beyond the end of the frame, the vertically-1ncvable strip 2 located within the recess in said frame, below said rod, links 8 pivotally connected at one end to said strip and similarly connected at their opposite end to said rod, and links 5 having a pivotal connection at one end to said strip and at their opposite end to said frame, arranged and operating substantially as described.

In testimony whereof I aiix my signature in presence of two witnesses.

CHARLES F'. RUSSELL.
