MEANS FR HOLDING SHEET-VENEER Vi/HILE BLEACHNG.

Application filed December 24 1914.

To all lvito/a t may com-cfm Be it known that we, Bnnnn'r'rn E. STRONG and Hanni G. Cremonese, citizens of the llnited States, residing at the city of J amestown, in the county of Chautauqua and State of lJew York, hav-e invented certain new and useful Improvements in Means for llolding Sheet-Veneer lVhile Bleaching, of which the following', taken in connection with the accompanying drawings, is a specification.

The invention relates to bleaching wood and particularly thin or easily bendable or warped pieces of wood like sheets of Veneer and thin boards; and the object of the improvement is to provide suitable means for holding the sheets of veneer so that they will not warp when placed in the bleaching co1npound and to provide means in combination with said holding means for separating said sheets of veneer so that they cannot touch one another though bound firmly to one another yet permittingl the free circulation of the bleaching compound to both sides of the sheets of veneer during the process of `li-leaching; and the invention consists in the novel combinations hereinafter set forth and claimed.

in the drawings, YFigure 1 is a perspective view of a portion of the bleaching yat with the sheets of veneer bound together yet separated from one another, the sheets of veneer and the vat and binding and separating means being shown in vertical section. F ig. 2 is an end elevation of an empty crate or binding frame as built up for supporting the sheets of veneer. F ig. 3 is a plan View of one of the sheets of netting showing the holding' pins of the crate or frame inserted through the mesh of the sheet of netting. F ig. e is a perspective View of one of the parts of the crate or frame for supporting the sheets of veneer. Fig. 5 is a perspective view of a filled crate or frame showing the sheets of veneer confined therein with the sheets of netting` interposed between said sheets of veneer.

Like characters of reference refer to corresponding parts in the several views.

The immoral designates a bleaching vat which should be of suliicient size to hold the sheets of veneer or thin boards 11 which it is desired to bleach and sufticient of the bleaching compound 12 to cover the veneer when placed in the vat 10.

The sheets of veneer 11 are cut around the Specification of Letters Patent.

periphery of logs from four tb twelve feet in length by turning said logs in a veneer cutting or shaving machine. Accordingly the sheets of veneer are the full length of the log and usually the full cut around the same, often attaining a width of four feet. lt is essential that these large sheets of thin veneer should not lbe permitted to contact with one another in the bleaching compound until the sap or native uices are entirely extracted. Should the sheets of veneer contact with one another before the extraction of the sap they would badly diseolor one another at each point of contact, since the chemical action of the bleaching compound upon the wood before the extraction of the sap causes such a discoloration or spotting.

in cariwing the invention-into practice, a desired number ot sheets of veneer 1l are brought into parallel relation with one another and bound in bundle form by means of a crate or frame composed of frame sides lil, which are connected to one another by means of removable pins la around the outer edges of the frames 13, a double number of holes 19 being provided along side one another so that a double tier crate may be built up with any of the frames 13, as shown in Fig. 2, when desired. The crate is preferably bound into bundle form by means of a suitable cord or binder which will not discolor in the bleachingcoinpound 12.

lhe spacing or separating medium einployed in combination with the crate to hold the veneer sheets 11 in parallel relation without touching one another consists of a sheet of netting or coarse webbing 1G preferably of suitable textile material such as cotton, seine, twine, silk, hemp, tiax, wool, linen or any other suitable textile fabric or fibrous material. rthis netting' 1G should be of a suitable open work'character and large enough so as to be easily slipped over the pins 14 as shown, therebyv not only holding the sheets separated in' combination with 'the crate but permitting the bleaching solution to reach all portions of thc sheets of veneer so that the bleaching action will be uniformly carried out. The absorbent character of the netting insures the subjection of those portions of the sheets of veneer touched by the fabric to the action of the bleaching solution, while the attachmentof the netting over the pins 14e insures the complete separation of each sheet of veneer from all other sheets confined in the bundle or in the Vat.

lt is apparent that the bundle may be easily assei'nbled by placing one of the trames 125 with the pins lll; therein, as shown in Fig. il; then irst a sheet ot netting 16 is placed thereon stretching the netting over the pins 1l and letting it lie llat upon the trame side 1B. This stretching is easily accomplished by the insertion ot' the pins 14 through the mesh oli' the netting 10. 191 sheet of veneer is then placed it'pon Vthe netting 16 and another sheet ot .netting is stretched thereover, the entire crate or trame being lilled with alternate sheets et netting and Veneer, after which the crate is bound by a cord 15 or other suitable means to thereby hold the netting and veneer i'irn'ily in position. The bundle ot' veneer thus erated is then submerged within the bleaching compound 12 in the vat 10, preferably with the veneer in the vertical position, as shown in Fig. 1. 0n account ot the buoyant duality ot the wood the bundle or bundles ot veneer have to be held beneath the surface olf the bleaching compound 12 pret'- erably by means ot a board 1T and standards 18 against an overhead beam or holding means.

lt is apparent that the netting or ita-brie 16 might be bound around the edges by traine work without departing trom our invention, but it is prelerred that the sheets ot netting should be unbound since they are more easily stretched over the pins 11, simple knotted cotton seine being preferred, since the knots form an eren space contactin g point between the sheets oit veneer holding` said sheets firmly in place. it is also obvious that cords might be woven around the pins trom one to another and term a separating medium. This, however, would not be as cheap or convenient as the use ot the netted fabric. The netted fabric is also strong and durable and may be used repeatedly.

lfe claim as new:

1. Means 'tor holdingsheet veneer during bleaching comjfirising, two trame sides 'tor holdingl the veneer in line, and removable means t'or connecting said trame sides near the outer edges to thereby hold the veneer in line between said trame sides.

2. Means tor holding sheet veneer during bleaching comprising, two trame sides for holding the Veneer in line, pins removably and adjustably connecting said traine sides lo hold the veneer therebetween and within depies of.'

said pinsto inelose the veneer in bundle form. v o

Means for holding sheet reneer during bleaching con'iprising, trame sides having holes therein around the outer edges, pins removably insertible in said holes to Connect said frame sides and hold the veneer in line therebetween, means conneetible to said pins lor separating the sheets ot veneer so that they will not touch one another, and means tor binding said trame sides on said pins to inclose the veneer in bundle form.

5. Means tor holding sheet Veneer' during bleaching comprising, frame sides having spaced holes therein around the outer edges, pins removably insertible in said holes to connect said trame sides and hold the veneer in line therebetweenv` sheets ot' netting engaging around said. pins to separateA the sheets ot' veneer so that they will not touch one another, and a oord tor binding said frame sides and netting and Veneer in bundle .torni Jfor submerging in the bleaching solution.

6. Means t'or nolding sheet veneer during bleaching comprising, wooden frame sides having spaced pairs of holes therethrough around their outer edges, pins removably insertible in said holes to build a crate for holding sheet veneer within said trame sides and pins, sheets ot t'abric netting sul'ticiently coarse ttor the insertion et said pins through the mesh thereot to sepa ate the sheets of veneer so that they shall not touch one another in the process ot bleaching, and means ttor holding the assembled trame sides and netting and Veneer together for subinerging in the bleaching solution.

in testimony Awhereof we have aliixed our signatures in the presence ot two witnesses.
