MEANS FOR DRYING OR CURIN G' PAPER-BOARU.

Specification of Letters Patent.

Patented March 5, I907.

Application filed February 3, 1902. Renewed Augnst'28,190 6. Serial No. 332,353.

To alt whom, it may concern:

Be it known that I, TnoMAs WV. i\IoFAR- LAND, acitizen of the United States, residing at Ul11CLgO,'iIl the county of. Cook and State of Illinois, have. invented certain new and useful Improvements in Means-for Drying or Curing Paper-Board and other Like Material, of which the following is afull, clear, and exact specification- My invention relates more particularly to means for handling large pieces of paper board between the operations of producing the green. board and drying it in a kiln or other suitable place, and it has for its pri-' With these ends in view my invention.

consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said-objects and certain other objects hereinafter appearing are attained, all as fully describedwith reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 isa vertical longitudinal sectional view of the table on which the board is received from the machine which produces it, the carrier or holder for the board being also shown in place on the table. Fig. 2 is a transverse section thereof, taken on the line 5 5, Fig. 1. Fig. 3 is a perspective view of the carrier or holder. Fig. 4 is an enlarged transverse sectional view thereof, taken on the line 4 4, Fig. 3. Fig. 5 is a view showing the carrier supported on the trolley, and Fig. 6 is an enlarged detail view of the trolley and overhead track in side elevation.

1 is a drying kiln or chamber, which may be of any suitable construction and provided with any suitable heating means, such as steam coils 2, arranged in the bottom thereof below a track 3, which preferably passes through end doors 4 5 of the kiln and which is provided for a truck or car 6. The bottom of this car or truck is of some suitable open construction, such as a number of cross slats 7, extending athwart the truck side beams 8, so as to allow a free circulation of air and heat up through the bottom of the truck. The sides 9 10 of theitruck-body are hinged at 11 at their lower edgesin any suitable way to the cross-slats 7, and such sides 9 10 are held in their upright position by cross-rods 12 1.3,arranged attop and bottom andat each end, these rods having removablenuts. 14, so thatwhen desired the side board 9 may be let down and thesheets of board 15 or other material to be dried or c ared may be loaded onto truck from the s1 e. may be stood up on edge without danger of falling. down while others are being loaded on, the opposite side 10 of the truck-body is tilted outwardly in the position shown in dotted lines in Fig. 3, and the boards 15' leaned against it. In order that this tilting In order, however, that the sheetsmovement of the side 10 may be limited, the

side 10 is provided with a headed lug 16, whichprojects through a slot 17 in a stop-18, which iszpivoted at its lower end, as shown at 19, to aprojection 20 on theend of one of the slats 7. Hence it will be seen that the hinged or pivotedstop18will not interfere with the free movement of side 10 when being stood up in its normal position, while it will automatically limit the outward move ment of said side and hold it in the proper position for supporting. the'boards 15 suffie ciently out of the perpendicular to prevent them from falling. over.

Asthe boards 15 are stoodup on edge on the car or truck in the desired manner corrugated plates 21 are interposed between them, the corrugations on the plates being extended vertically, as shown in Figs. 1 and 2, so as to hold the boards a slight distance apart, while at the same time touching and covering but a minimum amount of their surfaces.

On the left in Fig. 1 are shown the two final rolls 22 of the paper-board-making machine. It is understood that after the board 15 leaves these final rolls it will still be in need of further drying or curing and must be handled with more or less care to avoid bending, buckling, or breaking. As it leaves the final rolls it will be cut off in suitable lengths by any convenient means as it arrivesupon a table (shown in Fig. 1) consisting of a frame 23, having a table-top 24, composed of a number of short sections between which are interposed rollers 25 for easing the passage of the board across the table. As the board comes upon the table it is received by a holder or carrier, (shown in Fig. 3,) which is laid flat upon the table in such a manner that the board will project into its grasp. The short sections 24 of the table-top are grooved or recessed at 26 to receive the crossbars 27 of the holder, so that the inner faces of the cross-bars will be flush with the upper face of the table-top. To these cross-bars 27 are secured longitudinal top and bottom bars 28 29, which constitute, with the crossbars 27, a rectangular form of frame especially adapted to hold the board at both edges and on one side. The board may be held on the other side or top face by means of fingers 29, formed atone end of each of the cross-bars 27, and adjustable fingers 30, secured to the opposite ends of said crossbars. The adjustable lingers 30 are pivoted at 31 to ears or lugs 32, formed on an upturned end 33 of each of the cross-bars 27, so that the inner or free ends of the fingers 30 may be forced toward the board 15 for holding it snugly against the cross-bars 27, notwithstanding any variation in thickness of the different'boards manufactured. These fingers 30 may be thus held by means of setscrews 34, threaded through the outer ends of the "fingers 30 and adapted to impinge against stops 35, formed on or secured to the upturned ends 33, as shown in Fig. i. The carrier thus described is provided with a handle or bail 36, pivoted to one of the crossbars 27, so that after theboard has been proj ected along the table and is fairly within the grasp'of the fingers 29 30 it may be severed from the main board, the fingers tightened up, as may be required, and the carrier readily removed by attaching the bail 36 to some suitable lifting or conveying mechanism. For this purpose there is shown a trolley 37, which may run on an overhead wire 38 and may have a block and tackle 39, provided with a hook 40, adapted to engage the bail, so that the carrier, with the board therein, may be readily lifted from the table and suspended on edge, and thus conducted to a place upon any suitable truck, which is run into a drying-,kiln after being loaded.

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

1. In an apparatus for the purpose described, the combination of a table for receiving the board, and a board-carrier adapted to rest upon said table for receiving the board therein, substantially as set forth.

2. In an apparatus for the purpose described, the combination of a table over which the board may be projected, a boardcarrier arranged on said table below the upper surface thereof and adapted to receive the board as it is projected onto the table, substantially as set forth.

3. In an apparatus for the purpose described, the combination of a table upon which the board may be projected, a carrier supported on said table in line with and adapted to receive the board, said carrier comprising removable side clamps for holding the board removably in place, substantially as set forth.

4. In an apparatus for the purpose described, the combination of a frame of flat form, means at one edge thereof whereby the same may be suspended on edge, means at one edge of the frame for engaging the side of the board to be held and holding the same against the frame, and removable means at the other edge of the frame for also engaging and holding the board.
