TO ALL WHOM IT MAY OONGERN:

Be it known that I, JAPHETH CROSS, of the city of Adrian, Michigan, have in vented a new and useful Improvement in VVeather-Strips; and Ido hereby declare that the following is a full, clear, and exact description, which willpenable others skilled inthe art to make and use my invention, reference being had to the accompanying drawings, and tothe 'letters of reference marked thereon, making a part of this specification,v like letters referring to like parts. p i

My invention consists in the construction of a movable weather-strip for doors, in sucha manner that by the closing of the door the strips are made to throwout from the grooves in the 'edges and ends of the doorwherein they are embedded, against the jamhsand sill ofthe door-frame, the strips being drawn back again into the grooves upon theopening of thedoor. i

It consists, also, in a modified form of the above, whereby the movable strips, on ciosing -the door, are thrown out of grooves, cut in thejamb-casing, against the front edge and top end of the door, and again drawn into the grooves upon the opening of the same.

In the drawings t Y Figure l represents a perspective view of aY door-frame, with a door hung, and standing partly open, vand showing the top and one side piece of my improved weather-strip as embedded'in the.l door ready for use.

Figure 2 represents the Weather-strips as detached from the door, and in detail. i

Figure 3 represents a plane section ot` a modified form of my weather-strip, passing horizontally through the door and door-frame, midway between thc'top and bottom.

Figure 4 represents a vertical section passing through the red line a' y in iig. 3, omitting the door A.

A represents the door. i

B represents the door-i`rame.

a represents the weather-strip at the top of the door.

b represents the weather-strip at the hinged edge of the door.

c represents the weather-strip at front edge of the door.

d represents the bottom weather-strip.

f represents a bed-piece, with two inclined planes, similarly to the inclined planes on the two strips a and d, and is bedded into the groove in the top of the door, with its straight side down.

t represents a similar bed-piece, embedded into the'groovein the bottom end of the door.

17, in iig. 2, represents rubber, or other elastic material,.plaoed between the bed-piecesf and t andthe strip 6.'

m, n, 0, p, q, and r, in iig,-2, represent guide or steady-pins, to hold the strips a, c, 0l, and b, in position.

Z, in gs. 3 and'4, represent levers, turning upon the ,fulcraf and striking, at their outer ends, against th'e strip b', n and m being small steady-pins to hold the levers and strip b in position, allowing only a motion te and from the jamb.

7c is a small spring-catch, with a prong, z', which rests on the ends of the levers Z.

g are two coil-springs, which tend to hold the strip b against the bottom of the groove in the rahbet of the jamb of the frame B.

z and zlare the jamb andsill of the door.

Having thus described the construction of my improved weather-strip, its operation is as followst As you shut the door, A, the weather-strip, b, is brought against the jamb, e, and pressed into theigroove of the door. This strip, in turn, pressing against the rubber t", iig. 2, causes a longitudinhl sliding of the bed piecesf and t, which presses the weather-strip e against the jamb on the other edge of the door, at the same time raising the strip Wand lowering the strip d, by the inclined planes e, the one to form a joint against the jamb over head, the other to strike the sill of the door-frame B, the steady-pinsm andp preventing any longitudinal movement of the strips a and UZ. y

By opening the door, the coil-springs around the steadypins q and r, force the strip b partly out of the groove in that edge of the door, and by means of' the wires s, iig. 2,'draw the strip c back into its groove.

The bottom strip eZ is raised by a coil-spring in its groove inthe bottoni of the door.

The inclined planes e allow the top pieces a. and LZ to be brought deeper into their respective grooves as the bed-piecesj` and 7L are drawn in the direction indicated by the arrows on opening the door. 4

In figs. 3 and 4 the operation is as follows:

As the door A is closed (see iig. 3) the corner strikes against thc spring-catch 7n and forces it endwise, the prong z' pressing upon the ends of the levers Z, which, turning upon their fulcrf, press the strip D out of the groove in the jamb of the door-frame, and against the edge ofthe door, thus preventing the passage of wind bet-Ween them.

The same device is to be attached to the jamb over the top of the door.

Upon opening the door, a coil-spring throws the catch 7c back, when the coibsprings g dra-W the stript back in its groove where it was before.

I design using the device, which is shown in figs. 1 and 2, for windows also, in 'which case the window-sill would take the place, and cause the same eiect, as did the jamb z in pressing the Weather-strip Z1 into the groove of that edge of the door, and the cross-jamb of the window-frame is designed to produce the like result with the upper sash of the window. 4 v

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

C'Zaz'm.- 1. The combination ofthe strips a, b, c, and' d, with 'the bed-picc'esfand h, to be. used in doors and windows, all constructed in the manner andfor the purposes substantially .as set forth.

2. The combination of the spring-catch k with the levers l and strip b, constructed and operating in'the manner set forth.

JAPHETH CROSS.
