To all whom it may concern: 7

Be it known that I, PETER WIo'K STRUM, a citizen of the United States, residin at Lincoln, in the county of Lancaster an State of Nebraska, have invented a new and useful Antithreshold Automatic Weather- Strip, of which the following is a specification.

This invention relates to weather-strips for doors and contemplates the provision of a weather strip carried by the lower end of a door which shall be raised when the door is in open position and which shall be automatically depressed against the threshold or floor when the door is closed.

Another object of the invention is to provide a weathers/trip and means for raising and lowerin same when the door is opened or closed, which shall be incased wit-hm the lower end of the door, so as to be hidden from view, and to eliminate encumbering the door.

The present invention also aims for the production of a device of the character indicated, which shall be simple, durable, substantial and inexpensive in construction, which shall be simple, convenient and efiicient in operation, which is adjustable so as to depress the weather strip more or less, and which shall be applicable to various doors.

With the foregoing general objects outlined, and with other objects in, view as will be apparent as the invention is better understood, the present invention resides p in the novel construction and combination of parts hereinafter set forth and pointed out in the appended claims, it being understood that this device is subject to alterations or deviations in its details within the scope of the appended claims without departin from the spirit of the inventionr In t e accompanyin ferred embodiment o the invention has been illustrated, similar reference characters having been employed to denote corresponding parts.

carrying out the invention, the door D Y is provided with a recess 5 in its lower end extend ng from edge to edge, and face plates 6 and 6' are attached to the edges of the door over the ends of the recess 5." The plate 6 is attached to the edge of the .door which is hinged to the door jamb and the plate 6 is attached to the free or swingin the said plates being pre erably attached to the door, by*means of wood screws 22 The respective '

lates

6 and 6 have the opposite bushings which project into the recess 5 and have

bores

9 and 9 extending therethrough and through the bushings.

and 7" The said

plates

6 and 6 are also provided'with open slots 17 in their lower ends. The inner ends of the

bores

9 and 9", or those portions of the said bores within the bushings 7 and '7', are

enlarged and square vor non-circular-in contour as designated by the numerals .8 and 8,,

'the bushing '2" having a' partition 10" between the enlarged portion8' of thebore 9 and the outer port-ion of the bore, and the enlarged portion 8 of the bore 9 forming an inwardly facing shoulder or seat 10 within the bushing 7.

Bearing'blocks 1 1 and 11' are slidably mounted 1n the

bushings

7 and 7, respectively, the said bearing blocks being square or non-circular in contour to correspond with the inner portions or sockets 8 and 8" of the respective bores. The said bearing blocks 11 and 11' are provided with the respective sockets .12 v and 12' in their inner ends, and thebearing blocloll is arranged tonormal'ly' seat against the shoulder 10, thereby'preventing the outward movement of the'bearing block 11 beyond .the said.

shoulder.

A screw 14 is engaged into athreaded'jsocket 13 in the outer 'end of the bearing block 11 and has its outer end or head 15 projecting beyond the corresponding edge of the door, a jam or binding nut 16 being mounted on the screw 14 to contact with the block 11 so as to lock the screw 14 in any adjusted position to which it is set.

A screw 14 is engaged into a screwthreaded socket 13 in the outer end of the This rod 21 may be of any suitable material and gage so as to provide the proper resiliency or flexibility, and is of a length suitable for the particular door to which it applied.

A strip or head 18 has its ends engaging in the slots 17 of the

face plates

6 and 6 and has its upper edge contracted longitudinally and provided with a tubular portion 19 through which the intermediate por tion of the rod passes. This strip or head 18 is arranged Within the recess 5 and the rod 21 in passing through the tubular por- I tion 19 supports the same. Aweather strip or nearly straight,

20 of rubber or other suitable flexible material is secured to the lower edge of the head 18, the length of the head 18 and weather strip 20 being equal to the width of the particular door to which they are applied.

metallic button or contact plate 23 is secured to the door j amb J to which the door is hinged, and is preferably flush therewith and is designed to lie in the path of the head 15 of the'screw 14. This button or plate 23, however, is attached to the door amb, primarily to prevent wear and to eliminate marring or injuring the door jamb, and may be dispensed with if desired.

In the operation of the present device, the intermediate portion of the rod 21 will be normally raised when the door is open, so as to raise or elevate the weather strip and retract the same within the lower end of the door, the rod 21 assuming a straight, position. Then as the door is closed, the screw 14 will contact with the door jamb J or the contact plate 23 which will cause the bearing block 11 to be forced inwardly, in which event, the rod 21 will be flexed downwardly at its intermediate portion in order to depress the head 18 and the weather strip 20', so that the weather strip 20 contacts with the threshold or floor. As soon as the door in swung open, the rod 21 being flexible or resilient, will assume a normal straight line, or nearly straight line, position, thereby sliding the bearing block 11 outward against the seat 10 to project the screw 14 beyond the edge of the door and to again raise or retract the weather strip. In this manner, it will be seen that rota-i158 the weather strip is normally raised when the door is opened, and when the door is closed, the weather strip will be automatically depressed against the threshold or door so as to prevent the ingress or egress of currents of air underneath the door when the same is closed. The weather strip when depressed also excludes rain, snow, sleet and the like, and serves to efi'ectually close the gap between the lower end of the door and the threshold or floor when the door is closed. It will also appear that the lower end of the door, may be spaced more or less from the floor so that the door will escape rugs, carpets or the like lying, on the floor, the weather strip also being raised when the door is swung open so as not to interfere with objects on the floor underneath the door.

The bearing block 11 may be adjusted within the bushing 7 by rotating the screw 14, so that the rod 21 will assume a proper or slightly downwardly bowed position, when the door is opened, in order that the rod will be properly flexed downwardly I when the door is closed. The screw 14 may also be adjusted so as to project more or less from the edge of the door in order that the rod 21 will be sufliciently flexed when the door is closed in order to depress the Weather strip against the threshold or floor.

The present device is simple, durable, substantial and inexpensive in construction and may be applied to various doors in a convenient and ready manner without encumbering the door to which it is applied, and the device is also adjustable to suit the varying circumstances. The present device is also sensitive for the reason that a slight inward thrust of the screw 14 will buckle or flex the rod 21 to a considerable extent at its intermediate portion so as to lower or depress the weather strip, it being noted that the screw 14 may be adjusted so as to span the space or gap between the edge of the door and the jamb when the door is closed. It will be apparent, that the weather strip in being depressed may dispense with the threshold entirely so that the E'eather strip may contact directly with the oor.

From the foregoing, taken in connection with the drawings, it will be seen that the present invention provides a desirable device of this character for automatically closing the opening between the lower end or bottom of the door and the threshold or door when the door is closed, so as to shut out or exclude noises, light, air, dust, water, odors and the like.

Having thus described the invention what is claimed as new is 1. The combination with a door, of a pair of bearing blocks carried by the lower end of the door adjacent its edges, one of the blocks normally seating outwardly, a flexible truss rod having its extremities engaging the blocks, a weather strip carried by the intermediate portion of the rod, means for adjusting the other block for adjusting the normal position of the truss rod, and an adjustable member carried. by the former block and adapted to contact with the jamb of the door when the door is closed so asto flex the rod and depress the weather strip.
