APPARATUS FOR MANUFACTURING BUlLDlNG-BOARD FROM PAPER.
SPECIFICATION forming part of Letters Patent No. 269,786, dated December 26, 1882,
Application filed April 5, 1881. Renewed October 24, 188i. (No model.)
To all whom it may concern Be it known that I, S1LAs H. HAMILTON, of Lawrence, in the county of Douglas, and in the State of Kansas, have invented certain new and'useful Improvements in Apparatus for Manufacturing Building-Boaid from Paper; and I do hereby declare that the following isa full, clear, and exactdescriptiou thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side elevation of my improved machinery. Fig. 2 is an enlarged front elevation ofthe mechanism used for cuttingin lengths the completed board,and Fig. 3 is an enlarged side elevationof the journal-bearing of one end of a pair of pressure-rollers.
Letters of like name and kind refer to like parts in each of the figures.
The object of my invention is to enable building-boards to he produced at one operation from paper; and to this end it consists principally in the means employed for saturating sheets of paper with waterproofing composition, substantially as and for the pur-' pose hereinafter specified.
It consists, further, in the means employed for applying an adhesive mixture to the sheets of paper, substantially as and for the purpose hereinafter shown.
It consists, further, in the means employed for combining sheets ofadhesive coated paper and forming the same into a board,substan tially as and for the purpose hereinafter set forth.
It consists, further, in the means employed for adjusting to and securing in relative position the pressure-rollers of each pair, substantially as and for the purpose hereinafter shown and described.
It consists, further, in the means employed for cutting in lengths the completed board, substantially as and for the purpose hereinafter specified.
It consists, finally, in the combination and arrangement of the various parts of the machine, substantially as and for the purpose hereinafter shown.
My mechanism is intended for use in the carrying out of my nethod of manufacturing building-board from paper, in which several strips or sheets of such material are first simultaneously passed through a waterproofing mixture, arenext dried and then coated upon one Side each with an adhesive mixture, are next subjected to a heavy pressure to cause them to adhere togetherin theform ofa board, which is linallysevered into suitable lengths. In carrying into effect such method the paper A is formed in long strips, a number of which, in the form of rolls, are supported upon a suitable rack, B, in such position as to enable each strip to be unrolled and drawn out without interference from other strips. From the frame 13 each strip of paper A passes horizontally to, and over aroller, C, thence downward around a second roller, 1), thence for ward around a third roller, 5, and thence upward over a fourth roller, F, which said rollers, in connection with similar rollers for each strip of paper to be operated upon, are journaled in the order shown in Fig. 1 upon a frame, G, that is placed over a rat, H, and is capable of being raised above the same, or of being lowered until the bottom rollers, G and D, with their strips of paper, are below the upper edge of said vat. 'Ine vat H is intended to contain a waterproofing mixture, and is provided with steam or other suitable means for imparting to its contents any required degree of temperature. From the rollers F the paper A passes horizontally a suflicient distance to cause each strip to become thoroughly dry, during which transit said strips pass over and are supported by means of frames of slats or rollers I, that are arranged at suitable distances from each other. The strips of paper A from theframes I nextpass severally through or over a series .of vats, K, each of which vats contains an adhesive mixture, and is supplied with a brush-roller, k, that is journaled in such position as to cause its lower side to dip into said adhesive mixture while its upper side is in contact with the lower face of one of said strips. Said rollers are caused to rotate, and as said paper advances transfer to the lower face of each sheet a portion of the said mixture. I
In order that contact between the paper A and brush-roller It may be insured, a roller, k, is placed at each edge, front, and rear of the vat K, beneath which the said paper passes,
while, in order that all surplus adhesive mixture may be removed from said paper, ascraper, k is arranged in such position near the edge of said vat as to come into contact with the latter after it leaves said brush and before passing from sa d vat. From the vat K the strips of paper are brought together between two rollers, L, and from thence pass horizontally between a series of metal rollers, M, which are arranged in pairs, that are geared together and the different pairs connected by gearing,
so that said rollers shall simultaneously rotate with their impinging peripheries moving in a forward direction.
The rollers M are heated by means of steam or in any well-known manner, and, being arranged to impart great pressure to the paper passing between, cause the strips A to ad here tirmly together and produce from the same a board having great density. The relative positions of the rollers M of each pair are insured by means of a screw, m, which is placed between the journal-boxes m, at each end of the same, and is arranged so that by turning said screw in one direction said boxes are drawn toward each other and by turning it in an opposite direction they are moved apart. I
A screw, m placed above the upper box of each set enables said box to be held tirmly down to place when adjusted thereto.
As the board is formed it is cut into suitable lengths by means of a device shown in Fig. 2, which consists of a knife or cutter, N, which is suspended from asuitable frame, P, by means of two hangers, 0, above and at a right angle to the board to be cut, the arrangement being such as to enable said cutter to swing longitudinally to one side, so as to raise its edge above said board, as shown by the full lines of Fig. 2, and by moving in an opposite direction to assume the position shown by dotted lines of same figure, with its said cutting-edge below the lower lace of said board.
The cutter N is held in its elevated position by means of springs it, placed beneath its ends, and is moved laterally downward by two cams, Q, which are pivoted upon the frame P, and by means of radial arms q and a connectingbar, q, are combined so as to move simultaneously. As thus arranged, it will be seen that the cutter N impinges upon the board with a drawing out, which causes a clean division of the same and prevents waste.
Having thus fully set forth the nature and merits of my invention, what I claim as new 1. The means employed for saturating sheets of paper with a water-proof mixture, consisting of a frame of rollers, substantially as described, around which said paper passes, made vertically adjustable within a vat, substantially as and for the purpose specitied.
2. Asa means for applying an adhesive mixture to the strips of paper, the vat K, provided with the brush-roller k, guiding'rollers k, and scraper k combined to operate substantially as and for the purpose shown.
3. As a means for combining the sheets of adhesive coated paper, the pressure-rollers M, arranged in pairs and heated and combined to move simultaneously, substantially as set forth.
4. In combination with the journal-boxes m of the rollers M, the screw m, interposed between the same, and the screw m arranged to impinge upon the upper ofsaid boxes, substantially as and for the purpose shown and described.
5. As a means for cutting into lengths the completed board, the cutter N, arranged to swing longitudinally in a vertical plane and caused to impinge upon said board with a draw ing cut by mechanism substantially as described, substantially as and for the purpose specified.
6. As a means for making board from paper, the roll-supporting frame I5, the rollers O, I), E, and I journaled within the vertically-adjustable frame G over or within the vat H, the supporting-frames I, the ad hesive-mixture vats K, provided with the brush-roller 7c, guiding-rollers 7t, and scraper 70 and the pressure'rollers M, said parts being combined to operate in the manner and for the purpose substantially as shown.
In testimony that I claim the foregoing I have hereunto set my hand this 4th day of April, 1881.
SILAS II. HAMILTON.
