Application filed June as, 1914. Serial No. 847,819.

11,216,135, Specification of Letters Fatent.

To all whom it may concern:

Be it known that I, Fnos'r V. SIMPSON, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and t State of Wisconsin, have invented new and useful Improvements in Presses, of which .the following is a description, reference being had to the accompanying drawings,

thereof, said socket serving as the pivotal support for a platen stem 23 carrying a platen 24 at its upper end. The pivotal connection of the socket 22 with the base plate is preferably at the front thereof so that as the platen swings forwardly from its upright operative position it is slightly lifted and then permitted to fall to the position Which are a part of this specification.

This invention has for its object to provide a press for clamping the flaps of a paper or fiber box during the setting of the adhesive which holds them together.

Another object of the invention is to provide such a press with a swinging platen which will be capable of a movement to a position where it will be accessible for placing the box thereon or removing the box therefrom without obstruction by the plunger.

Another object of the invention is to perfect details of construction of a press of this character. 7

With the above and other objects in view the invention consists in the press as herein claimed and all equivalents.

' in which like characters of reference in Referring to the accompanying drawings cate the same parts in the difierent views:

Figure 1 is a rear elevation of a press constructed in accordance with this invention;

Fig. 2 is an end elevation thereof; and,

Fig. 3 is a plan view of the rack for supporting the box.

In these drawings 10 indicates vertical standards supportin a pair of parallel horizontal rods 11. A double yoke frame 12 is secured to the horizontal rods 11 and forms a guide with upper and lower bearings for a vertical plunger rod 13 carrying a plunger 14 at its lower end. A fiat head 15 is seecured to the upper end of the plunger stem 13 and is engaged by a cam 16 on a lever 17 which is pivotally mounted between a pair of upstanding cars 18. Within the central opening of the frame 12 there is a coil spring 19 surrounding the plunger stem and engaging at its ends against the lower end of the opening and a stop 20 on the plunger stem, the action of the spring being to lift the plunger whenthe handle 17 is raised to the position shown by dotted lines in Fig. 2.

Secured to the floor beneath the frame 12 is a base plate 21 having a socket 22 pivotally -rnounted between upstang ears shown in dotted lines in Fig. 2 where it is held by a toe 25 on the socket engaging the base plate. At the rear the socket 22 has an arm carrying a set screw 26 to engage the base plate and limit the backward movement of the platen to the position in which it stands in proper relation to cotiperate with the plunger as shown in Fig. 2.

Adjustably mounted on the platen stem 23 is a box supporting frame 27, preferably consisting of a pair of U-shaped strap metal frame sections bolted together with the platen stem 23 between them as shown in Fig. 3.

In operation the platen is thrown forward to the position shown in dotted lines in Fig. 2, while the plunger is in its upper position and the tubular box 28, which is shipped from the manufacturer to the user in the tubular form in acollapsed or knocked down condition is slipped thereon. The platen is of a size to just fit within the box and is removable so as to be changed for another of the proper size when the size of box is changed. The box rests on the box supporting frame 27 and the flaps of the box are folded over upon the platen where they are treated with silicate of soda or other adhesive and then the platen is swung to its rear or operative position and the handle 17 is brought forward to the position shown in full lines in Fig. 2, the cam 16 forcing the plunger downwardly against the action of the spring and against the folded flaps of the box. It is preferred to arrange a number of the presses on the same supporting-frame side by side so that one operator may clamp one after the other and each be left in its clamped position a sufficient length of time for the adhesive to set before its next operation. When the lever 17 is raised the spring 19 lifts the plunger and the operator draws the platen forwardly and removes the box-therefrom.

The press of this invention is of a simple construction, permitting of a rapid operation, and subjects the box flaps to great presplane of the said flaps when the plunger is in its upper position. Before lowering the plunger the operator presses the box flaps toward the center of the press and whlle holding them in this osition. the lever 17 is thrown to bring the p unger to its operative position. 1

In the claims'I use the words cam mechanism to include of course the equivalents thereof such for instance as toggles.

What I claim as new and desire to secure by Letters Patent is:

1. A press for sealing flaps of fiber boxes and the like, comprising a cam operated plunger, a swinging platen therebeneath adapted to move from an operative position in which it cooperate with the plunger to an inoperative position in which the plunger will not interfere with the boxes belng placed thereon or removed therefrom, and downwardly extending lugs at the rear and at oneside of the plunger against which the box flaps may be squared efore lowering the plunger. I

2. A ress for sealing fla s of fiber boxes and the 'ke, com risin a p unger, a swinging platen there eneat from an o erative position in which it cooperates with the plun er to an inoperative osition in which the p unger will not interere with the boxes being placed thereon or removed therefrom, an downwardly extending lugs along one edge of the plunger against which the box flaps may be forced before lowering the plunger.

3. A press for sealing flaps of fiber boxes and the like, comprising a plunger, a platen therebeneath adapted to move from an operative position in which it cooperates with the plunger to an inoperative position in which the plunger will not interfere with the boxes being placed thereon or removed therefrom, and downwardly extending lugs along one edge of the Flunger against which the box flaps may be orced before lowering the plunger.

In testimony whereof, I afiix my signature, in presence of two witnesses.

FROST V. SIMPSON. Witnesses:
