ALBERT w. MITCHELL, [OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO JOHNN. LEONARD,
TRUSTEE, OF NEW HAVEN, CONNECTICUT.
PAPER-BOX MACHINE.
To all whom it may concern:
Be it known that I, ALBERT W. Mr rcnnnn, a citizen of the United Statesof America, residing in the city of an endless chain of .plungers or formers New Haven, in thecounty of New Haven, in the State of Connecticut, have invented certain. new and useful Improvements in Paper-Box Machines, of which the following is a specification.
My invention relates to that class of machines in which paper boxes are formed from blanks which are scored or cut, and the sides are bent or folded up and the glued or pasted ends are folded together over a plunger or former. i
Myinvention is more particularly intended as an improvement in the construction of the forming and folding mechanism of the paper box machines for which I .applied for Letters latent June 6th, 1906, Serial, No. 320,486, and in which a stationary die is combined with passing through the die in succession.
n 'In' the accompanying drawingsFigure 1 is a sectional elevation through the die showing the plunger as it passes into theblank and is about to force the latter through the die; Fig. 2 is a sectional plan on the line 2'2, Fig.- 1; Fig; 3 is a view similar to Fig. 1, but showing the folding fingers retracted and the plunger passing into thedie; Fig. 4 is a corresponding plan view; Fig. 5
' tion; Fig. 6 is a similar view, showing the fi ngers prof, of the sides of theblank over the ends of the rectangujected to the folding position; and Fig. 7 is a sectional view showingmeans for yieldingly supporting the wings to shape the bottom of the box.
In these drawings, Cs the bed plate of the machine, P is one of the plungers or formers, carried by a: laterally projecting arm p, on a link P, which isto lie connected up to like adjacent links of the endless chain by pairs of short links .p. A continuous travel may be imparted to the endless chain of plungers P so thatthe latter pass I through, the forming die D in succession In the edge of the die opening is formed a notch d,-( Fig. '2) for the passage of the arms-p, which carry the plunger-s.
On opposite sides of thedie D, above the table 3, I
of the" guides on the, tabletop which maintained bent upright thesides of the paper blank to form the side walls of the box, asthe. paper web has been intermittently fed forward in the direction of the arrow,-Fig. 2, towards the die. D over the surface of the table 0.
The devicesso far described are substantially the same as like parts found in the machine of my above described application. i v j One of the features of myprese'nt invention consists in the improved mechanism for folding the end flaps f,

larformer I or plunger P, before it carries the blank through the die-to thereby fold up the end flaps of the bottom over the inturned side flaps. I The folding devices comprise at each end of the box a Patented Aug. 6, v
- slots in the side walls 55 and are projected inwardly by suitable means at the proper time to fold the end flap f, f, of the sides of the blank up against the end walls of the former P, (Figs. 1 and 2), and then at the proper moment are withdrawn again, as shown in. Fig. 3. For this purpose, each finger 59 is mounted by a vertical pivot upon the upright portion 57 of a horizontal slide 58 free to reciprocate in guides 56 on the table 0. Short reciprocating motion may be applied intermittently by any suitable means from a moving part of the machine. In Figs.- 2 and 4,- I have indicated for this purpose an upright rock shaft 61 connected by a crank arm.
62 to the slide 58. The upper part of the upright 57 on the slide .58 is connected by rods 65 to the upper ends of two levers 64, which are pivoted on horizontal pivots63 on lugs on the right hand side wall 55, and at their lower ends have pivoted to them the folding fingers 60. Thus when the slide 58 is'moved inwardly to project the fingers 59 across the ends of the plunger or former P, the fingers are simultaneously projected inwardly at the opposite side. i
An important feature of the invention consists in the provision of means for imparting to the folding fingers a movement towards and from the ends of the former P,
the outer face of each finger a cam surface 66, (Figs. 2, 5
in the side wall 55; so'that as each finger is projected as well as across the ends. For this purpose, I form on and 6), which can bear against the outer edge of the slot throughthe wall from its retreated position shown in up towardsthe end face of the former P and press the flap) of the blank against the latter accordingly. The manner of pivoting the. fingers 59 readily permits of this,
1 while in the case of the fingers 60, the like movement may be permitted by allowing a certain freedom of movement of the levers 64 on their pivots 63. provide side plates 5 5, which are in sheet continuations By the time the fingers 59, 60, have folded the side flaps f, the plunger- P will have started to press the box blank through the die D, and in doing so will fold up the gummed outer'or bottom flaps over. the side flaps f.
In order to get amore satisfactory action of. the plun- (go: P on the blank, when the plunger P descends into the partially folded blank,'and to obtain sharper corners and normally maintained'in the horizontal position v shown ,in Figs. 1 and byany suitable means, such as a spring 97, connecting arms 98 on the axles. 96 otthe wings. are flush with the surface of the feed table so that the folded box blank is fed onto the wings as it passes between the side walls 55. Thus while the plunger P is descending into the blank, the latter will be supported by the wings 95, until the plunger presses the bottom of the box firmly against these wings and then pushes the latter back on their hinges, as shown in Fig. 3.
I claim as my invention 1. A paper box machine. having a plunger and die with fingers for folding the side flaps against the end walls of the plunger and means for reciprocating said fingers'in a direction across said end walls, and means for simultaneously moving the fingers towards or from said end walls.
These wings when in their horizontal position.
2. A paper box machine having aplunger and die with slotted sidewalls over the die, folding fingers to be projected through such slots and having cam faces and means for intermittently projecting and withdrawing the fingers.
3. A paper box machine, having a feed table for the box blanks, a plunger and die with side walls over the die and yielding supporting wings normally held over the die flush with the surface of the feed table to support the blank while the plunger descends into it, whereby the boxes are formed with sharp corners;
in testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
ALBERT W. MITCHELL.
