WEATHER-STRIP AND DOOR-STOP.

SPECIFICATION forming art of Letters Patent No. 558,786, dated April 21, 1896. Application filed November 26, 1895. Serial No. 570,241- (No model.)

To aZZ whom it may concern.-

Be it known that I, ADOLPHUS M. DOYLE, of Leoti, in the county of \Vichita and State of Kansas, have invented a new and Improved "Weather-Strip and Door-Stop, of which the following is a full, clear, and exact description.

My invention relates to a combined weatherstrip and stop adapted for use in connection with doors and to be operated through the medium of a knob-spindle, and the object of the invention is to so combine the stop and weather-strip that they will operate together, and wherebythey may be readily and conveniently applied to a door and constructed in an exceedingly economic and simple manner.

A further object of this invention is to provide a connection between the door-stop and the knob-spindle of such character that the connection will not interfere with turning the spindle in either direction, and whereby the door-stop may be raised from engagement with the floor no matter whether the knob be turned to the right or to the left.

struction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the lower portion of a door, illustrating the door open and held open by the stop. Fig. 2 is a longitudinal section through a portion of the door, the said section being taken practically on the line 2 2 of Fig. 8, illustrating the weatherstrip in engagement with the threshold-strip. Fig. 3 is a partial side view of the door, the stop and weather-strip being in the position shown in Fig. 2, and in this view a portion of the casing of the stop is broken away. Fig. 4c is a vertical section through a portion of the door and likewise a vertical section through the attachment, the stop being shown in the position to hold the door open, or partially open, and the section being taken substantially on the line 4: l of Fig. 5. Fig. 5 is a perspective view of a portion of the door and of the attachment, the parts being in the position shown in Fig. 4 and the knob-spindle being in section; and Fig. 6 is an outer face view of a portion of the door, the said door being closed and a portion of the improvement shown in position thereon.

In carrying out the invention a horizontal pocket 10 is produced in the bottom edge of the door A, to which the attachment is to be made, and a weather-strip B islocated within said pocket, being pivoted near the upper edge of its inner or rear end, as shown at 11 in Fig. 1. The pocketis of such size that the weatherstrip may have vertical movement therein to a limited extent, and that portion of the pocket between the upper edge of the weatherstrip and the upper wall of the pocket is closed at the outer end of the pocket by a dustguard 12, which preferably consists of a metal plate properly countersunk in the front V61" tical edge of the door.

Adjacent to the front vertical edge of the door, at the bottom thereof, the stop C is located. The stop consists of a casing let, preferably of substantially cylindrical form, being provided with side flanges whereby the casing is screwed or otherwise secured on the door. In the bottom portion of the rear face of the casing 14 a longitudinal slot 15 is made, and this slot is in communication with a transverse slot 16 made in the door, and the said transverse slot 16 is preferably widest at that end which is in communication with the caslug-slot.

A pin 17 is pivoted in the transverse slot of the door, and the said pin is of sufficient length to extend from one end of the slot to the other, and through the slot 15 in the casing and a predetermined distance within the latter. This pin likewise passes through an opening or aperture 18 made in the Weatherstrip, the opening being larger than the diameter of the pin. The pin 17 may be pivoted upon the door in any suitable or approved manner. One means of accomplishing this result is shown in Figs. 2 and 6, in which it will be observed that a staple 19 is secured upon the outer face of the door by bending its legs to form spurs, the said spurs being driven into the door, and the bow-section of the staple is made to pass through an opening in the pin. A second and smaller staple 20 is then driven in the door and made to cross the main staple 19, holding the latter firmly in place.

The stop 0 consists of a body portion 21 and The bodypor a reduced or shank section 22.

tion 21 is made to conform in cross-section to the cross-section of the casing and has verti cal movement therein, and in the lower portion of the said body an opening 23 is made, which receives the free end of the pin 17, as shown in Figs. 2 and 4, while upon the bottom portion of the body of the stop an elastic facing 24: is securely fastened, and this facing is in the nature of a block, extending even when the stop is in its extreme upper position below the lower end of the casing 14, which is open, and the facing 24, which is preferably made of rubber or leather, has that face inclined which is presented to the door, the inclination corresponding substantially to the angle of the threshold-strip over which the stop must pass. The spindle-section of the stop passes through a suitable opening in the top of the casing, and within the casing the said spindle-section is surrounded by a spring 25, the said spring having bearing against the upper end of the casing and likewise against the shoulder formed at the junction of the body and the spindle of the stop.

An elongated slot 26 is produced longitudinally in the outer end of the spindle of the stop, and a crank-arm or crank-plate 27 is secured upon the knob-spindle 28 of the door, the lower end of which crank-arm is adjustably connected to the upper end of the stop by means of a link 28, the said link being passed through the slot 26 in the upper end of the stop and is capable of free movement therein.

In the operation of the stop and weatherstrip, no matter whether the knob-spindle is turned to the right or to the left, the stop will be drawn upward, compressing the spring 25. Therefore, supposing the stop to be in engagement with the floor to hold the door in open position, as shown in Figs. 4: and 5, by turning the knob-spindle to the right or to the left the stop will be drawn upward, and the pin 17, connected with the stop, which had been in a downwardly-inclined position, will be raised to a substantially horizontal position, carrying the weather-strip upward with it. The door may now be closed, and the stop will have been carried a suificient distance above the floor to clear the threshold-strip, thereby not chafing any carpet that may be laid upon it, and when the door is fully closed and the spindle released the spring will force the stop down firmly upon that portion of the pin 17 which enters the stop, carrying the pin to a firm bearing on the bottom wall of the slot 18 in the weather-stri p through which the said pin is passed, and forcing the said strip downward to a firm contact with the thresholdstrip, as shown in Fig. 2.

In order to open the door, the spindle may be turned either to the right or to the left, since the connecting-rod 28 will simply play loosely in the slot 26, which is of sufficient length to permit of the proper throw of the crank-arm or crank-plate 27.

In manipulating the spindle when the door is closed, at the end of the stroke of the said crank plate or arm 27, the stop will be carried upward a sufficient distance to draw the pin 17 also upward, and thereby slightly raise the weather-strip, so that it will not scrape along the threshold-strip or its covering as the door is opened. When the door has been opened as wide as desired and the knob-spindle is released, the spring 25 in the casing will force the stop downward to an engagement with the floor, and the weather-strip will be permitted to drop likewise a predetermined distance, as shown in Figs. 1 and 5.

The weather-strip is preferably provided at its bottom with a facing of a yielding material, such as leather or rubber. It is evident that the knob-spindle will turn sufficiently to permit of the connecting-rod 28 to straighten itself as the spring forces the stop downward to an engagement with the floor, as shown in Figs. 1, 4, and 5. If in practice it is found desirable, the crank arm or plate may be omitted and the wire of the connecting-rod 28 may be attached directly to the knob-spindle.

Ilavin g thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a stop adapted for attachment to a door, a spring normally exerting pressure downward on the said stop, a weather-strip adapted for pivotal connection with the door, and a pin likewise adapted for pivotal connection with the door, the said pin being passed through the weather-strip to an engagement with the said stop, the engagement being so made that the said pin will communicate the pressure from the spring controlling the stop to the weather-strip, as and for the purpose specified.

2. The combination of -a vertically-movable stop, a pivotally-mounted weather-strip having an opening therein, and a pin pivotally mounted off the stop and weather-strip, the pin being passed through the opening in the weather-strip and having loose connection with the stop, substantially as described.

3. The combination with a door having a slot extending through a portion of the door and communicating with the lower edge there of, the door also having a triangular passage intercepting the slot, a pin having one end pivotally mounted in the small end of the triangular passage and passed through the same and projecting beyond the door, a weatherstrip pivotally mounted within the slot and having an opening through which the pin is passed, a casing extending vertically with the door and secured to the side opposite the side to which the pin is pivoted, and a stop vertically movable in the casing and having loose connection with the pin, substantially as described.
