v :Application filed Nqvember 9, 1887. Serial No. 254,713. (Nomodel.)

and State of New York, have invented certain;

new'and useful Improvements in Weather- Strips, of which the following is a specification.

io protecting strip; and my'improvement con- Y I have improved the weather-strip in which a tubular cushion is employed as the weathersists in the particularconstruction of the device,whereby it is rendered more durable in maintaining its tubular form, and" by Which its connection with its metallic supporting part is rendered lstrongV and firm and of sim- Plc construction.

The preciseimprovementconssts in the provision whereby thejoined edgesv of lthe tubular cushion are re-enforced by a binding rib4 or cord of textile material, and the provision Vofa metallic bindingplate adapted 'by itspeculiar construction to be bound over and upon the re-enforced edges of the tubular cushion.

as I will now describav andmake such precise improvement the subject of my claims.

To enable the public to understand and those skilled in thc mechanic arts to construct my said improvedy invention, I will describe it as follows, to wit:` v.

Referring lto the accompanying drawings, Figure l represents a front view of. a section of a window, having my improved weatherstrip'A secured upon the sill thereof. Fig. 2 is ay section of the thin rubber cushion c formed into shape for use.v Fig. 3 is a seetion of the metallic binding-strip m,fashioned into shape to receive the flexible cushion c. Fig. 4 shows the two 'edges of the rubber cushion c laid together and firmly stitched or otherwise. secured to a textile strengthening cord or strip, s, ready' to receive the corrugated covered side' against theparts to be stripped,

ing the 'same onto the textile strip or cords.

lThen pass' any suitable strip of thin metal through rotary dies, which produces by a single rotatory ,motion the corrugated stri p m readyto 5 5f receive the'thin edges and'streng'thening-cord :ofthe rubber cushionlc, and by a second rotary motion the outer edge, o o', ofthe `me- Q tallic binding-strip mis turned underand upward to' receive and firmly holdfwithin4 its f6o coiled recess the 'corded edges s offr'ubber vcushion c. The inner edge, of the metallicV i binding is also turned under at'the'sarne time by the same rotarydevice to v,produce a rigid` bearing (when the strip Ais nailed in posi- 65' tion upon the Window-sill) at the footnof the cushion c. 1

. vIt wiu'be noneeathat the bindingen-ipsa f secured to the outer side of thelapped partsof',` the tubular cushion 'and at the top re enforcedy edges of such lapped parts, and that the `u'p-v.` Y,

per edgeof the binding-plate.' is so bent and f formed as to grasp -thisre-enforced edge part, so that the re-enforcng rib will lie in'ahollow on the inner side of thegrasping-edge of the plate, withthe latter on one sideonly of the cushion-lappingparts, as shown in Y The other edge of this plate is folded in closedV relation to thisinnerside, so as to form arounded bearing, l,which, being clamped upon the rubber cushion at the joining of its lapped sides with its tubular body, prevents-injury or Y breaking of the rubber at such-joining. In-- termediately between these grasping and bear-,p ing edges ol' the plate it is formedfwith auxin-v ward projecting rib corrugation, n, which formsa ridge bearing the length of the strip f y upon'the lapped parts of the cushion, `and it is through this bearing-ridge that the lapped 'sides of the cushion are nailedwiththe unandY thereby bind the plate'at the middleof its widthandat its edgesl hard uponthe outer-f` side of the lapped parts of the cushion. y This Y f construction so firmly binds the lapped-cushionparts that they cannot be pulled apart, while the lapped rounded'edge presses firmly uponthe ytubular base without cutting it.

What is claimed in this application for/Letters Patent is-- 1. A weather-strip cushion consisting'ofaj i tubularlpart, c, having rits edges lappedand y re-enforced by an edge-binding ridge or cord,

ull

s, in combination with a metallic binding-` plate having oneedgegrasping the re enforced lapped edges of the cushion, its other edge having a closed lap or fold forming a bearing upon the tubular part of the cushion at one side only of its lapped parts, substantially as only of the cushion-lapped parts, substantial] y as described.

3. A weather-strip composed of a rubber tubular part having its lapped edge parts bound by a metallic plate placed upon one side only of such lapped parts and formed with a semi-tubular edge part, o o', for grasp ing the lapped edge parts, an inner under lapped edge forming abearing, and a. longitudinal bearing-rib, n, on its inner side, as' shown and described.

Signed at the city of New York,in the county of New York and State of New York, this 82h day of September, A. D. 1887. v
