T {LZ/Z 1077.072?, zit Hefty concern:

Be it known that I, DANIEL SCHUYLER, a citi- Zen of the United States. residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a new and useful Damper Cord, Teather-Strip, and Door- Cushion, of which the following is a specification.

An object of the invention is to provide a neat cheap strong durable weather-strip and door-cushion which can be easily fastened in place with tacks or staples and which will practically cover and conceal such fastening means when they are driven in place. f

The invention broadly includes a dampercord comprising two cushions and a connecting-web providing beaded edges and an intervening channel. Preferably the web is at the back and the channel is on the face of the appliance, and the web is formed of the flexible material which ensheaths the main bodies of the cushions and forms the outside of said cushions.

The accompanying drawings illustrate the invention.

Figure 1 is a. fragmental view of a weatherstrip and door-cushion embodying this invention and secured in place and viewed from the front or cushion side. Fig. Q is a cross-section of the saine on line II Il. Fig. 3 is a rearview of the same, showing the edges of the flexible strip spread apart at one end. Fig. 4 isa section on line IV 1V, Fig. 3. Fig. is a longitudinal section on line VV, Figs. 1 and 4. Fig. 6 is a cross-section on line VI VI, Fig. 5.

This weather-strip or damper-cord is composed of a web 1 and two cushions 9. 3, directly connected with vthe web and forming the edges of the damper-cord and also forming the walls of a single channel 4 between the cushions. The web preferably lies at the back of the strip, the two cushions being fastened to the web and projecting forward to forni the cushion-face and the. edges of the damper-cord. The channel 4 is formed between the cushions on the face 6 of the strip, against which the door (not shown) comes when it is closed. The damper-cord is fastened in place by staples at appropriate disdoor-jamb 8, the heads of the staples being chambered in the channel 4 and practically7 concealed by the overhanging walls thereof, formed by the cushions 2 and 3.

The damper-cord is preferably constructed of two round cords 9 10 and a ilexible strip 11, of suitable material-asdenim, for instancebent around the cords, and a row of stitches 12 extends along between the cords, fastening the edges 13 14 and the middle 15 of the flexible strip together. Said flexible strip is lapped at its edges between the cords at the back side of the damper-cord, the outer edge 13 being turned under, and the row of stitches 12 eX- tends through the turned edge 13, the inner edge 14, and the middle 15 of the strip, thus pulling the middle portion 15 of the strip down between the cords to form the channel 4. It is to be noted that the triple thickness formed by the lapped edges at the 'rear of the damper-cord gives a stiffness to the ileXible strip at the back side of the damper-cord, so that the natural tendency is to draw the middle of the flexible strip in between the cords, thus to form a deep channel with overhanging walls, in which the staples 7 will be chambered and practically concealed.

The damper-cord may be applied to many uses; but itis especially designed for use as a cushion and seal-for the doors of the system known as the perfect sliding-door system, and its peculiar construction enables the builder to so equipv the doorway that automatic and other sliding' doors will come to sealed position noiselessly and Without rebound and will exclude cold weather, airdraft, and sound in a superior manner.

The damper-cord may be made with great ease and rapidity by means of a special sewing-machine attachment which was invented and manufactured for this particular work.

By t'ne construction shown the web is formed of four thicknesses of the denim or other flexible material, which forms the sheaths for the cords, so that when the staples or tacks are driven therethrough into the joint 8 there is no`liability of tearing loose.

The cords are preferably braided of cotton and are peculiarly elastic, returning readily tances apart, driven through the web into l to form whenever the door is opened.
