GEORGE XV. SNYDER, OF XVESTERN COLLEGE, IOVAQ WEATHER STRIP.

SPECIFICATION forming part of Letters Patent No. 309,580, dated December 23. 18184.

Application filed Ju nel0 1884.

To aZZ whom it may concern Be it known that I, GEORGE W. SNYDER, a citizen of the United States, residing at \Vestern College, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in eather-Strips, of which the following is a specification.

The object of my invention is to so construct a weather-strip for a door that it shall automatically rise above the threshold the door is opened,and close tightly upon it when the door is closed, performing the operations more perfectly, and by means of simpler mechanism, than any other weatherstrip known to me.

The invention consists in a strip of rubber cloth or other water-proof flexible material secured to a shaft pivoted to the door near the bottom, and connected with mechanism for automatically turning it as the door is opened and closed, and also in a supplemental flap fastened to the door above this mechanism and overlapping the lower flap, for the purposes of protection and the complete exclusion of water, as will be hereinafter more particularly set forth.

In the accompanying drawings, forming a part of this specification, Figure 1 represents an elevation of. the lower part of a door with the weather -strip attached, Fig. 2, a plan view of the same slightly ajar; Fig. 3, the detail of the mechanism for actuating the pivoted shaft, and Fig. 4 a crosssection of the in vention in a vertical line.

Similar letters of reference indicate corresponding parts.

A strip, 1), of flexible water-proof material, preferably rubber cloth, is secured to a small shaft of wood or metal, 8, pivoted in brackets e e, fastened to the lower part of the door A and near the sides thereof.

For convenience in fastening the strip to Q the shaft, it is placed between the shaft and a metallic plate corresponding to the shape of the shaft, and having holes at suitable dis tances for tacks or screws. This also renders the connection of the parts more close, uniform, and permanent. Between the shaft and the door is pivoted a lever, E, adapted to turn the shaft by its vertical movement (N0 model.)

through the medium of a hole or recess, 1', made to loosely receive the end of a pin or lug, 0, projecting from the back side of the shaft 3'. The lever E is preferably made thin and wide at its free end to give it weight, and at the same time occupy as little room as possible. An arm extends vertically. from the pivotal point and at a right angle to the body of the lever, and to this arm is connected a sliding rod, F, passing through the upper part of the bracket e, and extending a short distance beyond it. This rod. is designed to abut against the jamb O shortly before the door is closed, as show 1 in Fig; 2, and by its longitudinal movement raise the lever E, which in turn rotates the shaft 8 and shifts the position of the flaps from that indicated by the dotted lines in Fig. 4 to full line, as it will be seen that as the door is closed the flap is pressed downward upon the threshold 13, and as the door is opened the weight of the arm serves to raise it clear of the threshold and all obstructions. I prefer a weight to a spring by reason of its greater certainty and durability, though it will be obvious that a spring would answer the pur pose.

To prevent the water from running/behind the lower flap already described, a supplemental flap, l), is secured to the door a suitable distance above the first, and overlaps it, as shown. This, as wellas the former, is preferably provided with a metallic plate, 11, through which tacks or screws are driven. I' prefer to have these flaps of flexible material rather than stiff and hinged, as they are better adapted to fit inequalities in the threshold and eachother, and close over partial obstructions without leaving 1nuch,if any, opening for the admission of water.

I am aware that a weather-strip adapted to close down upon the threshold when the door is shut is not broadly new, and I do not claim such as my invention; but

"What I do claim, and desire to secure by Letters Patent, is-- l. The combination of flap D, shaft .3, and

lever E, substantially as and for the purpose set forth.

2. The combination of flap 1), shaft 8, le-

Ice

In testimony whereof I affix my signature in presence of two Witnesses.

substantially as and for the purposes herein S. M. ENDIOOTT, set forth.
