VENEER-DRIER.
SPECIFICATION formingpart of Letters Patent No. 767,654, dated August 16, 1904. Application filed May 25, 1904. Serial No. 209,640. (No model.)
To all whom it may concern.-
ton, in the county of Sufiolk and State of Massachusetts, have invented a new and useful Improvement in Veneer-Briers, of which the following is a specification.
In the patent granted to me on J'anuary19, 1904:, N o. 7 50,058, I show the vertical platens of a veneer-drier provided with horizontal pins adapted to support narrow veneers at levels above the bottoms of the platens, the pins projecting from the face of one platen into registering openings provided in the face of the opposing and adjacent platen. The present invention is a modification of the construction shown in said patent and is intended to accomplish the same resultnamely, that of increasing the capacity of the driers in operating upon narrow veneers by providing means for supporting the narrow veneers between the upperportions of the platen-faces.
The invention consists in the novel features hereinafter described.
In the accompanying drawings, Figure 1 is a front elevation of a veneer-drier provided with my present invention. Fig. 2 is a face view of one of the platens. Fig. 3 is a partial vertical section of the drier.
In said drawings, 5 5 represent a series of platens supported at their ends by swinging rods 6 and connected by the pipes 7 to a suitable header or source of steam-supply. At each side of the series of platens is atoggle 8, by the lengthening of which the platens are forced together, so as to compress the veneers between them, and by the shortening of which the platens are drawn apart to allow the escape of the vaporized moisture and the inser tion and removal of the stock, the toggles be ing operated by any suitable mechanism Instead of short pins fixedly secured in the platen after the manner shown in my said patent I now use rods 10 of sufiicient length to extend through the entire series or through a portion of the series'of platens, and the openings 11 the rods can be put in or taken out whenever desired. The entire series of platens are preferably provided with the openings 11, and such openings are in alinement, and the rods fit them loosely,-so that the putting in and taking out of the rods is rendered easy. The openings are provided in such numbers and in such locations as desired in the platens, and
the rods are taken out whenever wide veneers are to be dried. The rods are adapted to support the narrow veneers in the same manner as do the pins of my patent, and I have shown in Fig. 3 veneers 12 as resting upon them. The openings in the platens are preferably lined by short tubes or bushings 13, substantially as in the patent. The supporting-rods should be of suitable length, so that the platens in which they are inserted will not be drawn oif of them when the platens are opened, and they should fit loosely in the openings, so as not to create unnecessary friction upon the platens when the latter are opened and closed.
By this invention I am able to dry two or more courses of veneers between adjacent platens simultaneously without increasing the size of the platens or the amount of steam required, and the platens are held apart by the stock bothat the top and bottom, and as the supporting-rods are positioned variously at diiferent times there is but little appreciable .wear upon them. The rods 10 need not extend through the entire series of platens and, in fact, need be passed through only so many of them as are needed for the narrow stock, so that wide stock may be dried at the same :time between the platenst'nrough which the transverse openings therethrough arranged alinement, in combination With loose rods in- 1n ahnement, 1n combination with loose rods serted 1n the openings and acting to support IQ for supportlng veneers passed through said the veneers.
