E. cRADcSY GLUEING OUT SLABS Filed July 51, 1922 Patented May 13, 1924.
PATENT @FHQE.
EDWARD GRADDY, OF BRISTOL, ENGLAND.
Application filed July 31, 1922. Serial Np. 578,778.
To all whom 2'25 may concern Be it known that I, EDWARD CRADDY, residing at Bristol, in the county of Gloucester, England, a subject of the King of Great Britain and Ireland, have invented certain new and useful Improvements in or Relating to Gluing-Out Slabs, of which the following is a specification.
This invention relates to means for applying pasting material, such as the so called cold glue to paper sheets or the like in the manufacture of covers for boxes and other containers.
The usual method of gluing out on a solid slab is wasteful of material and incurs a considerable loss in time through having to replenish the slab with glue after every two or three sheets have been glued out. The present improved gluing slab is economical in the use of material and does away with the process of covering the slab with glue after every two or three sheets have been glued out, thus reducing the time necessary and consequently the cost of gluing out considerably.
It comprises a shallow tank such as a tinned steel container with wired edges, for example 3 inches deep, and made of any size to suit requirements. 7 This container is filled with cold glue to within about one inch of the top and on this is placed the gluing-out slab which floats on the glue, and is made of a wood framework with a fabric screen, through which the glue percolates so as to leave a film of glue on the surface.
The fabric screen also acts as a filter for the glue and avoids any grit getting on to the paper, which in the old method is a continual source of trouble.
The benefits claimed for this device are,
economy in use of glue, considerable saving in time, and better workmanship.
In the annexed drawing Fig. 1 is a cross section on line 1-1 of Fig. 2, and Fig. 2 1s a plan of a portion of the container and slab. Fig. 1 is a cross section illustrating a modification of the construction.
A is the shallow tank preferably stamped in tinned steel with a roll over and wired edge. B is a rectangular open wooden frame slightly smaller than the tank in plan, and C a sheet of canvas stretched on the said frame and held in place by battens D and corner pieces E. In Fig. 1 these battens and corner pieces are of wood. In Fig. 56 1 they are of metal, preferably aluminium, for its lightness and non-corrosive properties. F represents vent holes for air to escape from under the fabric when the slab is placed on the glue. Gr indicates the so- 0 called cold glue, an adhesive liquid, with which the tank is nearly filled.
What I claim as my invention and desire to secure by Letters Patent of the United States is In apparatus for applying pasting liq uids to paper and other sheets, a relatively large, floating skeleton frame having stretched on it a textile fabric which is freely permeable by the liquid to be applied and on 7 which the sheet to be coated is adapted to lie; said frame having a weight such that it will constantly and freely ride on the surface of the liquid, whereby a thin film of the liquid will be kept continually on the sur- 7 face of the fabric; substantially as described.
In witness whereof I have signed this specification.
EDWARD CRADDY.
