WEATHER-STRIP ATTACHMENT.

Specification of Letters Patent.

Patented June 1, 11915.

Application filed September 15, 1913. Serial No. 789,772.

To all whom it may concern:

Be it known that I, WILLIAM H. GODFREY, a citizen of the United States, residing at Somerville, county 'of Middlesex, State of Massachusetts, have invented an Improvement in Weather- Strip Attachments, of which the following description, in connectionwith the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in weather strip attachments especially adapted for sealing the bottom of doors, although the same is equally applicable to other uses.

The object of this invention is to improve and simplify the construction of weather strip attachments in which the weather strips are adapted to be withdrawn into the edge of thedoor or other device to which they are applied when the same is open and to be projected downwardly therefrom into engagement/with the floor or sill when the door is closed. In devices of this character the weather strip is guided at its ends and is moved laterally by means of links, toggles or other connections which are secured to and operated by an actuator.

.In most instances the actuator is located within a casing and has a portion which projects beyond the edge of the door and is adapted to engage with the door jamb as the door is closed. Such engagement with the door jamb serves to move the actuator longitudinally and to thereby act uponthe weather strip to move it laterally in the manner aforesaid.

In devices heretofore constructed the spring which operates to withdraw the actuator has been placed in various awkward positions interfering with other parts or making a complicated structure, especially when the spring is placed at the end of the actuatorthe connecting devices cannot be properly positioned to force down the extreme ends ofthe weather strip. In such devices also the actuator has been operated either directly or through an adjustable member secured thereto. v

In accordancewith my invention I recess the actuator to receive a compression spring and I provide an independently supported and adjustable plunger to cooperate with the actuator to force the same forward.

My improved adjustable plunger is carried by the end plate and fits closely therein presenting a neat and finished appearance.

By such construction the attachment is much more easily applied to the door or moving part, is capable of being made much stronger arlrd presents a better appearance when app 1e The novel features of the invention will more fully appear from the following specification and the drawings, and will be particularly pointed out in the claims.

In the drawing; Figure 1 represents a door partly in section showing this invention as applied thereto with the door closed; Fig. 2 is a similar view of a door partly in section showing this invention with the weather strip withdrawn into the base of the door and the plunger for the actuator extending through the edge of the door ready for engagement with the door j amb, a modified form of plunger being shown. Fig. 3 is a vertical sectional view on lines 33 Fig. 1. Fig. 4: is a sectional view of a lower portion of the door showing the end of the actuator, a slide abutting the same and a relatively adjustable thrust block and Fig. 5 is a sectional view of the plunger on lines 55 Fig. 4.

This invention is adapted to be applied to any form of door and may be operated with a sliding door as well as with a hinged door. In order to apply this invention to the door, the door is grooved and the weather strip attachment placed therein.

In the embodiment of the invention which isillustrated in the drawing of thisapplication, 1 represents the door, 2 a slot in the base of the door in which the weather strip attachment is inserted. End plates 3 and 4: which are fastened to the edges of the door serve to close the groove and also to prevent longitudinal movement of the weather strip. The end plate I is provided with an orifice 5 through which the end of the plunger is adapted toproject for engagement with thedoor jamb or other relatively stationary member.

The weather strip attachment comprising my invention consists of a channel shaped casing 6 U-shaped in cross section and made preferably of metal, which serves to receive the weather strip when retracted and also inolosesand acts as a guide for the actuator and'its spring in the manner hereinafter described.

. The weather strip 7 comprises a smaller channel shaped frame preferably of metal adapted to slide within the main casing 6,

- this embodiment may comprise a longitudinal member 9, preferably wood, rectangular in cross section, which fits within the base of the channel shaped casing. The casing thus constitutes a guide which embraces three sides of the actuator. Pins, 10, and 11 which pass through the sides of the casing adjacent to the remaining side of the actuator serve to confine it from lateral movement while permitting free longitudinal movement. a

The pins 10 and 11 preferably engage in recesses 12 and 13 in the actuator which re cesses are of just the necessary length to permit the desired movement of the actuator. -.-The actuator may however be made sufliciently narrow so that these pins may be placed below it without interfering with the weather strip.

The upper edge of the actuator is providedwith a longitudinally extending recess 14 which is adapted to receive a helical compression spring 15. A pin '16 passed through the casing serves as an abutment for one end of the spring while theother end thereof abuts against the shoulder 17 at the other end of therecess. It will be apparent that by the construction the helical spring is securely held in place and is prevented from buckling by reason of the factv that it is wholly inclosed by the casing and actuator. Being a compression spring 'it cannot break loose and become inoperative.

In assembling the above construction the spring is placed in the recess in the actuator and the actuator thereupon thrust within the U-shaped casing. l/Vhen inplace the pin 16 is passed through the casing at the end of the spring. If, however, the pin passes through between the spirals of the spring it will serve equally well since it would merely shorten the effective length of the spring. Itwill thus be observed that the construction is very simple in character and very easily assembled.

I provide an adjustable plunger independently supported in the end plate 4,

to engage the door j amb or other relatively stationary element and force the actuator forward. In the structure illustrated a sleeve 18 is secured to or madeintegral with the end plate and is positioned in alinement with the actuator 9. This sleeve is slotted asishown at 19. it slide 20 engaging the actuator at one end is mounted in this sleeve and is provided with fins 21 projecting into the slots 19 in the sleeve. The outward movement of the slide is limited by the fins engaging the ends of the slots. The end of such as indicated at 24.

In order to impart lateral. movement to the weather strip from the longitudinal movement of the actuator links 25 or other" suitable connections well known in the art are prov ded. In the constructions heretoforenamed the connections between thesetuator and the weather strip: have been placed at such distances from the end of the weather strip that it could warp up at its .ends and leave a crack sufiicient to admit considerable. amount of air. In devices constructed in accordance with my invention 1n which the spring for the actuator is seatedln a recess in the back thereof ample provision is made forplacing the links or' other means connecting the actuator and the weather strip ad acent to the ends thereof" so that upon the forward movement of the actuator the ends of theweather strip will be projected firmly against the door sill. i

In the form of my :invention illustrated in Fig. 2 the actuator is formed with an integrally reduced end to provide. a plunger,

26 which is adapted to project through the orifice into the end platem the manner aforesaid. Inthe device in the form of my invention illustrated; in Figs. land 4: the links25' connecting the actuator with the Weatherstrip are likewise closely adjacent V to, the end of the weather stripand actuator s nce the space required for the sleeve and its plunger occupy but about two inches whichls relatively small compared with the length of the weather strip.

reason of the adjustable plunger being thus lndependently mounted; not only is the device more easily applied to the door but 3 the possibility of breaking of a projecting portion which cannot be easily replacedby substitution of a new part is'avoided.

It will be obvious to one skilled in the art that various changes may be made with in the spirlt of the inventionas defined in" the claim.
