The iop oi this @mires may be secured under eine horizontal bei.' r over the er1- irenee. The eoliensof Lire @arrives door has e l pocket or hem .5' all the wey ingress, @eritemingj :i liar or roller. The emis oi this loer er rend to the veriieei edges of the @eures door. A. series of liorizonizii poeiiei's are fomieil en. the ezm'ves door. 'Flies ilioeiies, however, ile not extend the entire width of ilie (1i-mms, bei stop short of its ve u.

A thin ber 'zu is placed in eee" ai seid pockets (see Fig. El) to stiffeu The @am door iii the erosswiee direction., bei; elim. to remain flexible in elle veriieei direeiiim eed capable of rolling up, es shown in Fig.

When thefeenves or iiexibie door each Vertical marginal enige e ie el-4 movable pressure-strip i?, 'which w takes position in the rebbet e sind seid canvas edge against the embw ip @mail thereby makes a tight join'o.

The canvas door opened by raising from. ta.. bottom to alle top. In the presen@ inl-- sten-.fe this is done by means of corde. Two corrie have one of their eues eiieeiiei'i to Elie cross-ber fr on the inner side of iile eri-- trance, then exbenddown and under Lilie roi leru :l presses the Lire outer side of the Genres rior# "to ygulleys e y, y', and y, respectively, see-uri. .i er ilu.' entrance.

bei in ille boiiom hem s, end then. upiiririiori rails, and as the lower end s of the hinged strips F do not extend fully down to the floor they will take over or above the ends of the roller-bar andthereby hold it down close to the floor. Thus the canvas door Q serves to tightly closethe entrance to the dry-kiln.

The peculiarconstruction here shown for opening the canvas door by raising from the bottom may be changed or' modified. It is not essential that it roll up by a roller placed at the bottom.

The material for the door may be made tight-z'. e., waterproof and steam-proofby oiling, painting, or other known process.

If a truck in a dry-kiln standing on the inclined track should start forward and push against this canvas door, the same would yield, the truck would run out, andthe canf vas door would swing up and allow the lumber-truck to pass and no damage to the door Iwould ensue, as sometimes happens in the use of wooden and other rigiddoors for driers.

Having thus described my invention what I claim is 1. A closure for the entrance to dry-kilns, having in combination an outer vertical facing-strip, d, at each side of the entrance; a vertical jamb-strip, c, also at each side, said jamb-strip and facing-strip together forming a rabbet extending to the door of the kiln; a exible curtain secured at the top of the entrance and the suspended end of the curtain carrying a roller, the marginal edgeof the curtain and the end of the roller having position in the rabbet; and a vertical pressurestrip, F, hinged to each facing-strip and adapted to swing around and press the margin of the curtain against the jamb-strip and its outer surface becoming flush with the surface of the facing-strip, the lower end, s, of said pressure-strip being shorter than said rabbet and leaving a space between it and the floor whereby the said lower end of the pressurestrip takes over the roller on the curtain and prevents said roller from being drawn up, as set forth. l

2. The combination in a dry-kiln entrance, of .a facing-strip at each sideof the entrance; a jamb-strip forming with the facing-strip a rabbet; 'a canvas or iiexible door which raises and lowers with its vertical marginal` edges moving in said rabbet, and said door provided with horizontal cross-pockets, t, whose length is lessv than the Widthof the canvas doorthereby forming a vertical margin, lu, ,extending past the ends of all the pockets the entire height of the door; a cross-bar, w, in each of said cross-pockets; and vertical pressurestrips which, when the canvas door is closed, have position in the rabbet and clamp the said vertical margins, 12, without clamping the said cross-bars, as set forth.

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