. WOODCORE-WALL-BOARD MACHINE.
Application filed June 22, 1921. Serial No. 479,567.
To oZZ whom it may concern:
Be it known that I, EMIL BLossrnLD, a citizen of the United States, residing at friend, in the county of Alameda and @tate of California, have invented new and useful improvements in Wood-Core-Wall- Board Machines, of which the following is a specification.
This invention relates to a machine for the manufacture of wood core wall board.
)ne of the objects of the present invention is to generally improve and simplify machines of the character described, and
especially to. provide a machine whereby a wall board, consisting of wood slats lined with cardboard on each side, can be economically assembled and produced and a smooth and uniform product and finish ob- Another object of the invention is to provide a machine whereby the cardboard and the wood slats are automatically assembled and-an adhesieve applied to cement the slats and the cardboard together.
521'? Another object is to provide novel means I delivering the wood slats to the point ere the cardboard is applied and in such a tanner that the successive slats will contact end to end along their longitudinal further to provide means for. applypressure to the'assembled product so as to obtain a uniform and finished surface on sides thereof.
- r objects will hereinafter appear.
1 invention consists of the parts and construction, combination and arrangeof parts as hereinafter more fully de- .5 ibed and claimed, having reference to accompanying drawings, in which--- 'g. l is a side elevation of the machine,
0: 2 is a central vertical longitudinal a cross section on line 33, Fig. 1.
is a detail perspective view of the g is a detail perspective view of the iin'shed product.
Referring to the drawings in detail, A in dicates the main frame of suitable construction, in which are journalled superposed 6 and the surface of the roller 8 is pairs of rollers such as indicated at 2, 3, 4 and 5. The rollers indicated at 4 and-5 are provided for the purpose of feeding the slats; the rollers 3 for the purpose of applying the cardboard lining, and the rollers 2 for the purpose of smoothing and finishing the final product. The rollers 3, 4 and 5 are disposed crosswise of the machine, as I are also the rollers 2. These last named rollers are, however, disposed on an angle for purpose-s to be hereinafter described.
' Disposed at one end of the machine is a wood slat receiver or holder B. This holder is more particularly illustrated in Fi 4. It consists of a plate 6, which is angufiu-ly disposed with relation to the machine and which is provided with side ides 7. Disposed directly below thevhol or B is a feeding roller 8, and formed on the surface thereof and extending from end to end of the roller is a series of cam shaped in 9. The spacing between the lower edge of the plattl:
no to the thickness of one slat. The heig l z of the cams or lugs 9 is similarly equal to the height of one slat and it is therefore obvious that the lugs will clear the lower end of the plate, and that the slats will be refioyed from the holder one by one during rotation of the feed roller. The slats removed by the lugs 9 are fed forwardly, first, by the action of the feeder which crowds the slats one after another in a. forward direction, and they are secondly fed in a forward direction by the rollers 4 and 5. The slats are next delivered to a glue pot or container indicated at 10, and the cardboard lining is then applied as will later be described. 7
To support the slats during their travel from the holder B to the glue container in which they are submerged, a pair of grooved side supports are provided as indicated at 11; the grooves proper being shown. at 12. The ends of the slats project into the grooves while the center portions of the slats are supported by upper and lower guide bars indicated at 14 and 15; said guide bars be ing separated to form a continuous slot which has a thickness equal to that of the slats passing between the same. There are v will engage or contact with a number of in reality two sets of feed rollers 4, and two sets of feed rollers 5; this beln plalnly shown in Fig. 3, that is a single s aft supports the upper rollers 5, and similarly a single shaft is provided for the lower rollers 5, but the rollers are secured at each end of the shaft, as actual experience has shown that the surface thus presented is more than sufiicient to feed the slats in a forward direction. The slats fed forwardly by the feed roller Send by the double set of rollers 4 and 5 finally enter the tank or container 10 which contains the glue or.
other adhesive employed. The tracks or guides supporting the. slats and indicated at 16 are arranged in a manner snnllar to the guides 11, 14 and 15. They are however curved as shown in Fig. 2 to cause the slats to be completely submerged and therefore thorou hly coated before the paper or cardboard ining is applied. The paper is received from a pair of rollers shown at 17 and 18. The paper from the roller 18 passes under a guide roller 19 and then under the uppermost roller 3, while the paper from the roller 17 passes under a guide roller 20 and then over the lower roller 3. The upper and lower rollers 3 apply sufficient pressure to cause the paper or cardboard employed to adhere to the slats, which have already been thoroughly coated with adhesive, and, a uni-' tary product is thus formed which is finally completed and finished when thefinal pressure and smoothing operation has been applied, by the rollers 2. These rollers are preferably disposed on an angleso that they slats at one time. This is important as it imparts a uniform and smooth finish to the product before it is finally discharged from the machine.
From the foregoing description it can readily be seen that the operator employed will, practically speaking, have only one duty to perform, towit, that of piling wood slats in the receiver or holder B. When the machine is in operation, it is obvious that the slats will he removed one by one and that when they are so removed, a forward movement will be imparted not only by the feed roller 8, but also by the rollers t and 5. By referring to Fig. 1 it will be seen that power is transmitted to the uppermost roller 2 by a chain or other drive indicated at 25. A gear is secured on the end of the shaft supporting the upper roller 2 and meshes with a gear 26 secured on the shaft of the uppermost roller3. This gear in turn meshes with a lower gear 27 secured on the shaft of the lower roller 3, and power is in turn transmitted to the'rollers 4 and 5 by the intermeshing gears 28 and 29 and by the sprocket chain drive generally shown; the number of teeth in each sprocket employed being such that the roller'sZ gigd. 3
same rotate in approximate unison; the rollers 4 a little faster, and the rollers 5 still faster. This is of great importance as it forces the slats together and insures absolute unison and physical contact of all of the slats before entry is made between the rollers 3 and the paper lining applied. It must further be stated that the several feed rollers employed are so adjusted with relation to each other that the pressure applied to the opposite sides of the slats is only suflicient to frictionally feed the same in a forward direction, .thus even though the speed of one set of rollers be greater than that of another, it is obvious that buckling or crowding of the slats will not take place as the moment they are forced together, slippage of one set of rollers or another will take place with relation to the slats.
Another important feature is the fact that the feed roller 8 is driven by a belt drive,
, tion of the guide or tracks 16, that is passage of the slats between said guides causes the abutting edges to slightly separate when travelling through the curved portion of the The glue thus enters between the abutting-edges and a uniform coating over the entire surface, to-wit, sides, bottom, top, ends, etc., is insured; the coating being so heavy and so thoroughly applied that additional paste is not required when the paper lining or covering is finally applied.
While certain features of the present invention are more or less specifically illustrated, I wish it understood that various changes in form and proportion may be resorted to within the scope of the appended claim, similarly that the materials and finish of the several parts employed may be such as the experience and judgment of the manufacturer may dictate or varying uses may demand. Y
Having thus described my invention, what I claim and desire to secure by Letters Patent is- A machine of the character described comprising a holder adapted to receive a series of slats in stacked formation, a receiving table, means for separating the slats in the holder and for removing and delivering the same one by one to the receiving table, 9 plurality of feed, gollers engagoghlg with the slats to advance the same, said feed rollers being arranged in pairs and certain of said pairs rotating at a higher speed than the others to cause the slats to 5 be assembled and to engage each other along their longitudinal edges, means for coating the slats with an adhesive, means for applying the paper covering to each side of the slats when assembled, and a pair of pressure rollers engageable with the slats after the 1 paper has been applied, said rollers being disposed on an angle with relation to the line of travel of the asembled slats.
