J. Y. BARCE, OF FAIRPORT, NEW YORK.

IMPROVED PACKING-PRESS.

Specification forming part of Letters Patent No. 30,3*12, dated October 9, 1860.

To all whom it may concern:

Be it known that I, J. Y. Parce, of Fairport, in the county of Monroe and State of New York, have invented a new and Improved Press for Packing and Enveloping Tobacco, Saleratus, and other similar Materials; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which—

Figure 1 is a front elevation of the machine. Fig. 2 is a section of the frame and table on the line x x, showing the working parts in elevation. Fig. 3 is a perspective view of the packing and folding box k, showing the folder m raised. Fig. 4 is a side elevation of the same with the package partly folded down.

Similar letters designate corresponding parts in all of the figures.

My invention has for its object the packing of articles of manufacture, in a pulverized or finely-reduced state, in papers of uniform size and appearance, and facilitating the process over the methods heretofore employed.

As represented in the drawings, A A is a table, in the center of which the working parts of the press are placed. These parts consist of the foot-lever B, hinged to the back of the table-frame at a, from which the stirrup-rods b b rise through guide-holes in the table, and connect at the arch of their top with the follower c. Connected with the foot-lever by a pivot between the stirrup-rods b b is a jointed elbow-lever, d, from which two rods, e e, ascend through slots in the table and connect with the yoke/, and a pawl, g, pivoted to the lower jointed section, falls against a stop, i, and causes lever d, to rise to a straight position, or nearly so, whenever the foot-lever B is depressed. This act—the depression of the foot-lever—forces down the follower c, and at the same time raises the funnel or formingtube h, the former movement pressing the material and the latter raising the tube, and on removing the foot a coiled spring, g, raises the foot-lever B, and with it, through the lever d and rods e e (which then stand erect) and yoke /, the follower and tube clear, so that the package may be removed. Thus the tube and follower are held by the yoke until next wanted, when, by a slight backward pressure with the thumb upon one of the rods e, near the surface of the table, the rods e e and lever d are thrown out of their perpendicular position and (in a full-sized press) the yoke/falls of its own weight, leaving the tube and follower in the hand of the operator.

A description of the process will more fully explain the operation of the machine. The funnel h, which is formed with, a square tube at its lower extremity, in the ordinary manner of construction for filling packages, is wrapped with a piece of paper of suitable size to envelop the contents designed for it, and the lower end is folded over the end of the tube in the ordinary manner and pasted, as is also the edge which laps at the side. The tube, with the paper upon it, is then inserted in the metal box k, which is of a suitable size to receive it, and the follower withdrawn, when it is filled through the funnel with the material, using a measure, gage, or weight to determine the quantity. It is then placed in the press, its position being regulated by the gage j, and the follower c is placed in the funnel, its stem being connected with the stirrup-arch by the notch Z. The foot is then applied to lever B, forcing the follower down and compressing the material and simultaneously raising the funnel. The foot being removed, the funnel and follower rise clear from the box k, in which the paper parcel remains, which is then removed to complete the folding and pasting·. The box k has hinged to its back a plate, m, bent into a rectangular form. The upper plane is of a suitable size, and so arranged as to just cover the top of the box when it is brought forward. When the box is removed from the press, the attendant brings forward the folder-plate m, which folds down that part of the paper o which projects above the top of the box upon the back side, just even with the top of the box. The paper is then folded down by hand at each end upon the plate m, which is chamfered thin at the edges, and which forms a foundation on which the paper is folded, without pressing upon or indenting the contents thereof. It also secures the important result of folding every parcel of exactly the same height and leaving the corners square, which cannot be done by the ordinary method of folding by hand upon the contents of the paper, as, from the yielding nature of the materials, the angles become pressed inward and rounded. When the front side of the paper has been folded down, the plate m is sprung

30,342 out by bearing with the fingers on the projection at the hinge. The paper is then secured by pasting, and the package, being removed from the box by raising its loose bottom on the pin p, is completed. Neatness and uniformity of the packages are secured by this method, and they bear transportion much better than when made in the ordinary manner, as their true form admits of their'being packed in cases in large quantities so closely as not to burst from carriage.

The press is operated with ease, and greatly facilitates the process of unpacking the stuff. A set-screw, r, regulates the position to which the lever B is allowed to rise to adapt it to packages of different sizes. The rods b b and e e may be altered in length to adapt them to packages of different lengths or sizes, as they are connected with the wood portion (or if wood is not used, with a metallic nut) by a screw-thread, enabling them to be increased or diminished in length and adjusted with exactness by simply turning one or the other of their parts.
