UNITED STATE-S PATENT Or'nron.A

RUSSEL I). BALDWIN, or SHENANDOAH, IoWA.

IMPROVEM ENT lNwEATHER-STRIPS.

Specification forming part of Letters Patent No. 211,3] 5, dated January 14, 1879', application filed i November 6, 1878. i

To all 'whom it may concern:

Be it known that I, RUSSEL I. BALDWIN, ot Shenandoah, in the county of Page and State ot' Iowa, have invented certain new and ence being had to theaccompanying drawings and to letters of reference marked thereon, which form a part of this specification.

My invention is an improvement in weatherstrips, by which rain and wind are prevented `from driving in under outside doors of dwellings, &c.

My invention consists ot' a weather-strip composed of a plate provided with a lug or projection arranged to swing into a vertical position upon its lower edge, and a second plate fixed to the bottom of a door, Said plates forming automatically a vertical joint by closing the door against the said rst plate or its projection.

In my drawings, Figure l is a front elevation ot' the door and jamb as seen from the outside. Fig. 2' is a vertical section. Fig. 3 is a detail showing the form of the movable plate.

Similar reference1etters indicate like parts in all of the figures.

Referring to drawings, A is a metal plate provided with a lug, a, which rests on the sill of the door between the beveled edge of the carpet-strip B and the rabbet-bearings of the door-frame, and when the door is open lies snugly against Said beveled surface, with its lug a extending above the horizontal surface ofthe carpet-sill. 4

The carpet-sillB is of the usual form, of wood, clad with metal, and provided with a slot on the open side next to the jamb to receiye the lug a of the plate A.

C is the door, having its bottom rail provided with a metal plate, D, which is securely fastened thereto. This plate does not extend the entire width of the door, but is shortened at the open side to clear the lug a. 4

The lower corner of the door is notched and plated at g to receive and form a bearing for the lug a to bear and slide against when the door is being closed.

The under or bottom edge of the door is cut away to form, together with the plate D, a U- Shaped groove, to receive the plate A when the door is closed.

My device is simple, and can be applied to any doorway, not even requiring the skill of a mechanic to adjust andV put it in position.

I t is operated as follows: The door being open, the strip or plate A rests against the carpet-sill B, with its upper edge ilush with the horizontal surface of said carpet-Sill, and the projecting lug resting in the notch provided for it. As the door is closed, the Slotbearing g, coming in contact with the lug a, forces plate A upward and outward, it entering the while the U-shaped recess or groove in the bottom of the door, until said plate A rests snugly against the plate D, which happens simultaneously with the closing ot' the door against its rabbetbearings. A close joint is thus formed between door-sill and plates A and D.

I am aware of the patent to Corbit, No. 95,773, in which is a plate permanently pivoted in the doorway, said plate being thrown into place against a curved plate attached to the door by the movement ofthe said door as it comes against a curved arm attached to said pivoted plate, and to such I make no claim.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

'IheV weather-strip described, composed of plate A, provided with lug or projection a, and arranged to swin g into avertical position upon its lower edge, and plate D, fixed to the door, said plates forming, automatically, a vertical joint by closing the door against the plate A or its projection, substantially as and for the purpose set forth. r

In testimony that I claim the foregoing as my own I aflix my signaturein presence of two witnesses.

RUSSEL r. BALDWIN.
