BOX-COVERING MACHINE.

SPECFIOATION forming part of Letters Patent No. 475,324, dated May 24, 1892.

Application filed April 27, 1891.

To all whom, t may concern:

Be it known that we, DANIEL F. LAFEAN and FRANK X. DEvLiN, citizens of the United States, residing at York, in the county of York an d State of Pennsylvania, have invented certain new and useful Improvements in B0X- Pasting Machines; and we do declare the fol-V lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

Oui-invention has reference to machines for pasting strips of paper or other material preparatory to applying the strips to paper boxes along the edges thereof for the purpose of finishing and strengthening the boxes.

The invention has for its object to simplify the construction of such a machine and to render it more durable, more eflicient in use, not so liable to get out of repair, and more easily repaired than machines heretofore constructed and used for the same purpose.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, the invention consists in the construction and the combination of parts hereinafter described, and then claimed, reference being had to the accompanying drawings, forming a part hereof, and in which- Figure l is a side elevation of the machine. Fig. 2 is a vertical longitudinal section through the same; and Fig. 3 is a front elevation of the paste-applying drum, broken away and partly in section.

In the drawings, the letter A designates a trough designed to hold the paste or glue and resting upon abase B, from which rises a bifurcated standard C, braced to the base by diagonal bars C. The trough is provided with a drum D, composed of thin sheet metal, preferably copper, opened at both ends and having an internal diaphragm or partition E, designed to sustain the drum against collapsing and at the same time form the two chambers on opposite sides thereof, so that access may be had to the interior of the drum from both sides for the purpose of removing any indentations that may accidentally be made in the surface of the drum, which if allowed Serial No. 390,529. (No model.)

to remain would cause some of the paper strip to pass from the drum without having the paste applied thereto, and consequently form an im perfectly-stripped box. This is important, as it obviates the necessity of sending the drum to the shop for the removal of its heads when otherwise formed in order to permit access to the interior for the purpose of such repairs. This construction also makes the drum lighter than when lotherwise constructed, as only a single partition need be used, and that being located near the central portion of the drum will afford a strong and substantial brace to the drum. A sleeve or hollow shaft F passes through the drum, and next to the diaphragm E on each side thereof is provided with vcone-shaped caps G, designed to brace the connection between the diaphragm and the sleeve.

Through the hollow shaft or sleeve F there passes loosely a shaft H, on which the drum and its shaft turn, the shaft having its bearings in the two standards I, rising up from the trough and being movable from one t0 another of a series of holes J in the standards, so as to adjust the drum up or down to come in contact with the paste or glue, as there may be more or less of it in the trough. The trough is also provided at one end with. a cross-bar K, raised above the top edge of the trough and at a point between it and the drum with a tension or hold-down rod L, located below the top edge of the trough and intended to hold the traveling paper strip against the face of the drum. On the opposite side of the drum there is a rod M, located similarly to the rod L and intended to serve the same purpose, and between it and the end of the trough is a raised bar N, which serves as a scraper to remove surplus glue or paste from the paper strip, as indicated in Fig. 2 of the drawings. The rods `L and M serve also as guides for the paper which is drawn over the drum.

The trough at the end where the pasted strip is delivered for application to the boX, as indicated in Fig. l ofthe drawings, is provided with a curved guard or plate O, which serves not only to support the 'paper strip at that end, but also as a scraper to remove any excess of the paste or glue that may nothave been taken olf by the bar N. This plate or IOC guard O being curved, any surplus paste taken oif by it will run down it into the trough.

The paper strip P to be pasted is supported in the form of a roll Q upon aremovable shaft R, supported in the fork ends of the standard C. This shaft carries a sleeve S, which turns freely on the shaft and constitutes a core upon which the paper strip is wound into a roll, and it prevents the paper from drawing so tightly as to be broken in moving it over the drum, as at times happens where the core is not used. On each side of the paper roll is a disk or guard-plate T, which lits loosely on the shaft between the paper roll and the fork ends of the standard in which the shaft is journaled. These plates serve to guide the paper strip evenly from the roll andto prevent it from slipping sidewise from off the roll and to prevent its frictional contact with the fork ends of the standard, and as a result the roll turns easily and there is no unnecessary friction to do dainage to the paper, and yet the paper is kept taut so that it will not form into loops or folds that would interfere .with the satisfactory working of the device.

The operation is apparentfrom the foregoing description without needing further amplification.

The .several parts can be made of any material desired. It is also obvious that there maybe made changes in the details of the several parts Without departing from the spirit of the invention, and although wehave the drum to repair damages to the shell without separation of the shell and said partition, substantially as described.

2. In a box-pasting machine, the combination, with the trough for containing the paste, of the hollow rotatable drum for transferring the paste, composed of a spindle or shaft having a centrally-disposed partition-plate and a sheet-metal shell mounted upon said plate and projecting beyond both sides thereof, and the cone-shaped caps inclosed within said drum and bearing against oppositesides of the said centrally-disposed partition to brace the single partition on both sides, substantially as described.

In testimony whereof we aix oursignatures in presence of two witnesses.
