* ratnc a Now-:13, 1906.

A umim filed July 12, igos. Seria1No.825,914- a To all whom it may concern/.- I I ,Be it known'that I, HENRY BAETZ, a citizen of the United States, residing at St. Louis,

State of Missouri, have invented certain new and useful Improvements in Feed Mechanism for Drying Apparatus, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming a part hereof. My invention ha relation to improvements in feed mec nism'for drying apparatus; and it consists in the novel arrangetion of a drying apparatus with walls partly ment and combination of parts more fully set forth in the specification and pointed out inthe claims.

In-the drawings, Figure 1 is a side elevabroken away, showing my invention ap lied thereto. Fig. 2 is an enlarged hori'zonta section on the'broken line 2 2 of Fig. 1, andFig.

3 is a vertical section on line 3 3 of Fig; 2.

The present invention, though specificallydesigned as an improvement 1n connection with the drying apparatus patented to me under date of August 9, 1904, N0. 767,198, may be installed in any drier wherein veneer, lumber; or sheets of any description whatsoever are treated, the object of the invention being to so confine the pieces in their passage through the drying air-current that while they are free to shrink the tendency to warp is reduced to a minimum and in the majority of cases disappears altogether. This insures a substantially uniform product, the shape of'the dry piece conforming substantially to what it was before the drying operation, and hence minimizing the waste incidental to such operations. The feed mechanism herein, though eminentl adapted for the feeding of lumber, is app 'cable 'to any material which has a tendency to behavesimilarl under the same circumstances. The a vantages'of the invention will become better apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, and preferably reviewing so much of the patented apparatus with which the present feed mechanism is directly associated, 1 represents a suitable casing provided with a fanor blower F, located in a chamber 2, the air being drawn into the blower-casing and forced through the heater 3, and suitable pipe connections into the air-chambers or headers 4 4, spaced a suitable" distance apart, the hot air being discharged from the headers into and across of lumber or veneer being thus confine the space between them. Passinfi around each chamber. or header is an en ess conveyer 5 5, the adjacent lapsof the conveyers traveling jointly in the space between the chambers and forming a feed mechanism for header 4, as shown, the lower lap of the chain being allowed to sag. The chains of each cerr.- veyer are connected by a series of transverse bars or strips 8, substantially semicircularin' 7-5 cross-section, the curved portions being presented outwardly. These ares aced about three or four inches apart, .ma 'ng collectively a conveyer-beltwhose supporting-sur- I face is composed of a series of transverse ribs, bars, or slats, As the lumber ieces are fed between the adjacent laps of t es'e belts the pieces are gripped and heldb'etween the opposing members of each pair of slats, and. since the surfaces of the latter are rounded they contact with the lumber L, substantially along single lines-or very reduced surfaces, thus permitting the eziposure of a maximum surface of the lumber to the hot-air cur rents traversing thes ace betweentheheaders o 4 4- and permitting the hot air to freely circulate around the material treated. Each igce tween a series of slats or bars is revented from bending or warping durin t e dryin 5 process, and hence when fina ly remove from the drier the piece has under one little or no change in shape, save the smal per cent. 1n shrinkage incident to all dryingo erations.

Such features of constructions own, but

not referred to herein, are either well known or covered by. the patent aforesaid and require no, description in this connection.

Having described my invention, what I claim is-- i 1. A feed mechanism comprising a pair of juxtaposed conveyers, and having transverse rib formations between which the articles may be confined, substantially as set forth.

2. A feed mechanism comprising a pair of 1 1o juxtaposed endless conveyors having a series of transverse rlbs or bars spaced suitable disl 3. A feed mechanism comprising a pair 0 tances apart, the material treated being inserted between the adjacent laps of thereonveyers and held between the aforesaid transverse formations, substantially as set forth.

juxtaposed endless conveyers having a series of transverse rib or'bar formations curved in cross-section, whereby the articles inserted between the adacent laps are held in position substantially along lines of contact, subsantially as set. forth.

L In combination with a pair of hot-air chambers or headers spaced a suitable distanee apart and delivering. jetsof air into and; across said space, an endless conveyertravel-in aroundeachheader, the adjacent laps of t r e conve ,ers traveling inthe space between the hea ers, rollers on the sides of the eonveyers, a track or-c-hannel for the rollers, a series of transverse rounded barsor slats. forming the surface of each 0011-. vey-er, whereby the articles inserted between the laps are gripped and held along lines of contact and the air isfree to circulate around the articles, substantially as set forth.

5. In combination Witha pair of hot-air chambers spaced va suitable distance apart, a

f suitable endless conveyer operating 1n the space between the chambers and having transverse rib formations spaced. suitable distances apart for permitting the free circulationof air between and around said formations, substantially as set forth.

6. A feed mechanism comprising a pair of endless conveyers in juxtaposed relation, and having transversely-disposed rods or slats on their adjacent laps between which the articlesare ped, and held against warping, substantial y as set forth.

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