WEATHER-STRIP.

Specification of Letters Patent.

Patented Jan. Ml, 191i.,

Application filed March 23, 1910. Serial No. 551,081.

weather strip which will be automatically lowered to cover the space between vthe end of the door and adjacent surface ot the frame when the door is closed.

lith these and other objects in view, which will more fully hereinafter appear, the present invention consists in certain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying ('.lrawings and more particularly pointed out in the appended claim; it being understood that various changes in the form, proportion, size, and minor details of the device may be made,

within the scope of the appended claim,`

without departing from the spirit 'or sacrificing any of the advantages of the invention.

In the accompanying. drawings, forming a. part of. the specification:"-Figure 1 is a front elevation of the lower portion of a door and its 'trame partly in section and showing my improved device applied thereto. Fig. 2 is a similar view ot a door partly in section without the trame and showing the position of the parts when the door opened; Fig. 3 is a detail perspective of the frame engaging member. n

Similar numerals of reference are einployed to designate corresponding parts throughout.

rllhe frame is designated by the numeral 5 and the door by the numeral 6.

T he attachment about to be described may be applied. to either or both the upper and lower ends of a door. For convenience l have shown it applied to the lower end of the door and formed in the said lower end is a groove or channel 7 extending vertically.

The strip proper is designated by the numeral 8 and is preferably ot thin sheet metal corresponding in length approximately to the width of the door and in width is considerably less than the depth of the channel 7.

vThe supporting and actuating mechanism for the strip comprises a lazy-tongs, the bars ot which are designated by the numerals 9 and 10 the said bars being` pivoted together at their medial portions, as shownat 11. The lazy-tongs 'is arranged within the channel and connection between the lower ends of the bars and opposite end portions of the strip is established by means ot' a pair of links 12 and 13 the opposite ends et# catch are pivoted to the lower ends of the bars and opposite end portion of the strip. The end portion ot the bar E) or that adjacent to the heel end. of the door is connected to t-he door by means et a pivot pin Ll passing through an opening in the end portion of the said bar 9 and sides of the channel. rFhe free end of the opposite bar 1G is provided with a nose which includes an elongated shank 15 arranged in a lateral opening formed in the side of the door, the said shank terminating in a beveledhead 1G which normally proliects beyond the side ot' the door and in position to engage with the door frame 5.

A staple or its equivalent 17 is driven into the door and straddles the shank 15 and encircling the shank with its opposite termi nals bearing on the staple 17 and inner end or' the head 16 isv a helical compression spring 18, which normally holds the head 16 projected through the. opening and the strip S retracted within the channel.

ln the operation ot the device it being assumed that. the door is in open position and the head 16 projected through the opening, whereby the strip will be well within the channel so that its lower edge will be above the surface ot' the lower end of the door, a movement of the door whereby the toe end of the latter will engage with the 'frame will result in the head 16 likewise engaging with the trame, whereby the nose will move inwardly against` the action of the spring lll and cause the lower end portions et' the bars to descend, thus inojecting the strip into en gagement with the threshold ot the door. lll/'henv the door is open and the head 1G moves out ot engagement with the frame the action of the spring will project the head, whereby the lower ends et the bars will nieve upwardly and retract the strip.

Thus it will be seen that the device is entirely invisible and will not become demK aged by engagement with external objects nor detract from the appearance of the door to which it is applied. It will be further observed that the device is exceedingly simple in structure and inexpensive in manufacture, and which may be applied to most forms of swinging doors now in use.

In combination with a door provided in its lower end with a channel, and a guide arranged 'adjacent to one end of the channel; of a vertically movable strip located in the channel, a pair of bars crossed at their inter' mediate portions and pivoted together, one

of said bars being pivoted at one end between the sides of the channel, and a link connection betweenthe opposite end of said bar and one end of the strip, a link connection between. one end of the other of said bars and the opposite end portion of the 20 strip, an elongated shank member slidingly itted in said guide and having one end lixed to the opposite end of the last-named bar and provided at its outer end with a beveled nose, and a helical compression spring bearing on said guide and nose, and yieldingly holding the latter beyond one side of the door. K

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