RICHARD SMITH, OF SHER'BROOK, CANADA` Letters Patent No. 91,780, dated June 22, 1869.
IMPROVBD MACHINE FOR FINISHING- PAPER BOXES.
The Schedule referred to in these Letters Patent and making pari: ofthe same.
To all whom it may concern..-
Be it 4known that I, RICHARD SMITH, of Sherbrook, in the Province of Quebec, in the Dominion of Canada, have invented a new and' useful Finishing-Press for Paper Boxes; and I do hereby dec-lare the following to be a full and correct description of the same, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view ofthe machine, seen .from the front.
-Theobjeet of this invention' is'mo applyt'o paper boxes made direct from the pulp, and when partially dry, a second or finishing-pressure, in' order to coudensethe material, and impart to the boxes a smooth surface and sharp, well-defined outlines.
The invention consists of a machine ofthe peculiar construction hereinafter described, for effecting the object above specified. It is intended to be used in conjunction with the machine for making paper boxes direct from the pulp, for which I received a patent, November 17,1868, or with any othermachine for the same purpose.
lo enable others to make and use my machine, I will proceed to describe its construction and operation, referring to the accompanying sheets of drawings by the letters of reference marked thereon.
The machine stands upon a square case or bed-plate, z, from which rise four stout columns, y y y y, sup porting the table x, which is ofthe same size and form as the bed-plate z.
A hollow cylinder, w, is attached to the lower side of the table a; by bolts b, passing through ilauges a.. and projects downward toward the .base Z.
Its'upper end is received in an opening in the table X, as shown in fig. 6, and on it rests the form E, on which the boxes to be pressed are placed.
From the upper side of table H rises the gallows V, supporting the mechanism for operating a cylindrical plunger, It, which works in a bracket, S, having a cylindrical bore of the proper calibre to receive said plunger,l and allow it to reciprocate vertically in it.
This plunger is operated by means of the handle H,
attached to tho end of the rock-shaft I, which turnsin brackets U, projecting from the rear of the gallows V.
(See iig. 2.)
This rock-shaft has a forked arm, M, to which one end ofthe link N4 is pivoted, the other end of said link being pivoted to the arms O P, which forma togglejoint i'or operating the plunger R. The upper end of arm O is pivoted to a forked lug, Q, projecting from the frontof the gallows V. The lower endoi arm P. is hinged to plunger It. When the handle H is drawn' forward, the plunger It is driven dwn, and when the handle H is thrown back, the plunger rises. The func- 'tio'uof plunger' R is to drive down the spring-pluhger To the bed plateZ isattached a forked stud, z, which serves as a fulcruni for treadle-lever J, which is pivot-ed to it.
To the inner end of this lever is pivoted the lowerA end of the rod u, the upper end of which is attached to an annular clearer, o, which surrounds the former E, and rises and falls in obedience to the movements of treadle J rising when the treadle is depressed, and fallin g when it is released. 4The function of this clearer is to throw out the finished box from the machine.
0n the table X, and surrounding` the form E, are
"four jaws, AB C I), working in guides G G G G, and
operated vby four toggles. The arrangement of these jaws and toggles is clearly shown in iig. 7. Jaw A is operated by toggle-arms ij, pivoted to the fixed stud h; jaw B, by arms s t, pivoted to stud lr jaw C, by arms m n, pivoted to stud Z; and jaw D by arms p q, pivotedv to stud o.
The toggles which operate the jaws are operated by levers F and K, (having their inlcra at j' and la),
which are respectively connected to them by the links c d and e g. (See gs. 1, 2, and 6.)
Each of' the levers F and K operates two pairs. of toggle-arms.
Above the guides G, and diagonally in reference to the linesof the jaws, a slide, L, reciprocates h0rizontally in ways L', attached to the gallows V. y
Fig. 3 is a detached perspective view of this slide, and lig. 5 is a transverse vertical section of' it, through the spring-plunger w.
In the forward end of this slide is a vertical cylindricalperforation, which receives the cylindrical plung er w, allowing itfree vertical motion.
Similar but smaller holes are connected with the larger one, and receive spiral springs (see iig. 5) which react upwards.
A circular plate, x, is. screwed to the lower end of plunger w, and another plate, y, (fig. 4,) is screwed on to its upper end.
Against the ends of this plate y, the spiral springs act to raise the plunger wtill the upper surface of plate y is flush with the upper surface of slideL.
Pressure applied to plate y forces the plunger w down. When the pressure is removed, the spiral springs force it up to its original position. rIhis pressure is applied by plunge'rit, operated by handle H The slide L has a handle on its forward end, and is operated by` hand, being drawn forward by the workman when the upper pressure is to be applied, and shoved back when the nrcssure is relieved.
'H is thrown back, and the plunger w rises.
The sliding movement is given to L, to allow'the form E to be uncovered for the insertion and delivery of thel box, while the plunger w can be brought over it at the proper time for giving the desired pressure to the bottom of the box.
The operation of the machine is as follows:
The slide L beingt-hrown back, and the jawsA B O D open, the paper box or hollow article, which has been made of pulp and partially dried, is placed on the form E, which is made of the exact size and shape toreceive it. The leverF is then brought up till the jaws A B come in Contact with the edges of the jaws G D. Lever K is then raised till the jaws C I) are driven in against the sides of the box. The slide L is no w drawn forward, till the plunger w is directly over the form E, when the handle H is drawn forward, which drives down the plate :c x upon the bottom of the box. The pressure is now complete. The lhandle Levers K and F are depressed, to release the jaws A B C D, and the foot is applied to the treadle-J, which raises the clearer'v, and throws out the finished box.
It is obvious that the form, and size of the form, jaws, and plunger, can be varied to any extent to suit the size and shape of the article to be pressed.
The form E-lnay be made hollow, or inl halves, and so that a blast of air may be applied to throw oi` the box when pressed.
The ends of the jaws that come in contact with the box may be perforated and covered with wire gauze,
.to allow of' the escape of water, or they may be engraved with any desired pattern, so as to emboss the vsurface of the box, if preferredl' Having thus fu'lly described my invention,
lVhat I claim, and desire to secure by Letters Patent, is
1. A machine for imparting a finishing-pressure to boxes and hollow articles made from paper-pulp, by
receiving them on a for and subjecting them to lat- Iarranged, and operating as described.
4. l'lhe form E, arranged for conjoint operation with the jaws AB C D and the plunger w, iu the manner set forth. j
5. The lclearer v, constructed, arranged, and operating in the manner and for the purpose set forth.
The above specification of my saidk invention, signed;
and witnessed at Lawrence, this 14thfday of May, A. D. 1869. RICHARD SMITH.
