PACKAGE.

Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed June 2, 1916. Serial No. 101,369.

To all whom it may concern:

Be it known that I, J OSEPH B. Wooonurr, a citizen of the United States of America,

residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented a new and useful Package, of which the following is a specification.

My invention relates to wrapping large or bulky and heavy piles or stacks of material, and more especially to the wrapping and the piling and wrapping of wood pulp on supports, and resides in the peculiar manner of building up the pile of wood pulp and applying the wrapping thereto, and in the particular wrapplng and wrapped pile or stack, all as hereinafter set forth.

Heretofore wood pulp, which is produced in large and comparatively thin sheets, has been wrapped in separate packages and these packages have been stacked, one on top of another, on supports or skids ready for shipment. Each of these packages con-, tains a number of thick sheets, each of which latter is made by folding and superimpos g5 ing a plurality of the thin sheets, and presslng them in a hydraulic press into a compact mass, which forms the thick sheet or unit. The sheets or units are completely wrapped, that is, covered on all sides, with wrapping paper, and the packages thus pro- I duced are stacked on the skids, as previously stated. These stacks with their supporting skids are shipped from the pulp mill to the paper mill. At the paper mill the wrap- 85 pings are removed and the pulp used as required.

'Much time, labor, and expense, both for labor and wrapping material, are thus involved, and the primary object of my inven- 40 tion is substantially to reduce, all of these items, which I am able todo with my improved package and through the method of making the same. Moreover, I insure the stability of the stack, while protecting the pulp as thoroughly and completely as the old way and'by the old means.

Other objects and advantages will appear in the course of the following description.

I attain the objects and'secure the advan tages of my invention by the means and in the manner illustrated in the accompanying drawings, in which 7 Figure 1' is a perspective v1ew of a stack of-wood pulp sheets or units piled in the new way, and illustrating thefirst step [of thewrapping'process; Fig. 2, an enlarged perspective view of a small pile of such units, showing more clearly the manner of foldlng and superimposing or stacking them; Fig. 3, a perspective view of the'elements shown in Fig. 1, but illustrating the second step in said wrapping process; Fig. f4, still another perspective view, which is lllustrative of an additional step in said process; Fig. 5, a perspective view of the finlshed package, and, Fig. 6, a perspective view of a finished package containing the thick sheets'o units, portions of the wrapper belng torn off to disclose some of the units within.

Similar numerals refer to similar parts 1 throughout the several views.

\ Wood pulp is formed into sheets for shipment, and roughly or generally estimated one of such sheets may be said to be from one-sixteenth t o three-fourths of an inch, thick, and to have an area containing several square feet.

In the last view, the stack or pile. is made up of thick) sheets or units 1 placed one above the other, the bottom unit resting on In building upa pile with unpressed sheets of wood pulp, I take a plurality of such sheets, which latter have beenplaced together evenly, and fold them over, or under at one [edge for a third of their length, more or less, 'to form a unit 3, and place such limit, with the short fold or lap, as 4, .un d'erneath, on a skid 2; and I form, in a similar manner, a second unit 3 andlay it in reversed positionon said skid and said first unit, or so that the'short lap. 4 of said second unit lies directly on saidskid with that portion of said first unit that overlays and extends beyond its short lap, that is, the long-lap, and the major portion orlong lap of said second unit lies partly on the'second unit short lap and'partly on the aforesaid long lapof said first unit, bridging the gap or covering the'joint, as the case maybe, between saidsecond unit short lap and the immediately adjacent part of said first unit. A third unit 3 is formedand added to the stack, this unit being arranged with its short fold orlap 4 resting on the first unit and the longitudinal edge of said lap abutting or approximately abutting the contiguous edge of the second unit. Uponthe second and third units a fourth unit is placed after be ing folded, with its lap 4 on the same side of the pile as is the lap 40f the second unit. Other units are added until the stack is of the required height, the arrangement,

' whereby the laps 4 of one set of alternate units are on one side and the laps 4 of the other set of alternate units are on the opposite side of the stack, being maintained throughout.

By thus folding and piling the pulp, I am able to produce a well balanced and stable stack of suitable horizontal dimensions. The folded edges are evenly distributed and lo-' cated at the sides where they prevent sag- 1 ging and afford the necessary support. A

stack five to six feet in height and weighing approximately half a ton is thus built up with the units 3, and after being inclosed in my wrapping is well ada ted to be shipped to any distance, and inde nitely to maintain its shape under reasonable conditions.

When the pile of units 3 (or 1) on the skid 2 reaches the desired height, the wrapping is applied thereto. This is done by placing a long and wide strip or sheet 5 of wrapping paper over the ile, with the center of such sheet directly a ove the center of such ile, wrapping the sheetabout f the pile, and securin the wrapper at the ends, in the manner 9. out to be explained. Owing to the size of the package involved, the services of two men .are usually required for the work. It is to be assumed, of course, that the paper sheet 5 is of the dimensions necessary for the purpose to which it is to be applied. The sheet 5 is applied lengthwise to the width otthe stack.

Proceeding now with the desc.iption of the wrapper and its production, and starting with the sheet 5 in the position described above and as shown in the first view, it will be clear, upon reference to Fig. 3, that the ends of said sheet are next turned down to cover the sides of the pile and form the sides of the wrapper. One of the aforesaid sides of the wrapper appears at 6 in all except the first two views, and that ortion of the sheet 5 which covers the top 0 the stack and constitutes the top .of the wrapper is designated by the numeral 7 in the last three V16WS..

It may be well to observe at this point that thewrap r has no bottom since none is needed. he stack or pile rests on the skid 2 and therefore is inneed of no protection underneath. This is a fortunate circumstance, inasmuch asit' would be a. diflicult matter to introduce any portion of the wrapping under the pile, and impracticable to build up the stack on or in the midst of a sheet of wrapping paper.

The portions of the paper sheetthat extend beyond both ends of the stack, at the top and sides, are folded vertically at the vertical corners of said stack, and obliquely from the tops of said corners to the approximate centers of the edges of the'top projecting portions of the wrapping, as represented at 8 in Fig. 4. The vertical end portions or ections of the wrapping, which have just been formed and are designated by the numeral 9, lie against the ends of the stack, and the edges of such sections overlap, as represented at 10. The end sections 9 extend above the plane of the top of the pile, and these elevated portions at each end together form a triangular flap 11. The flaps 11 are turned down, on the end edges of the top of the pile, against the faces of the sections 9. The sections 9 and the down-turned flaps 11 are. fastened or secured by some suitable the same, comprehends the Fig. 6 stack made I up of the thick pressed sheets 1, as well as the other stack made up of the peculiarly folded and arranged units 4.

The wrapper protects the stack from dust and dirt, and the thick heavy paper used for the wrapper is also a protection against molsture.

What I claim as my invention, and desire.

to secure by Letters Patent, is

1. A package comprising a support, a stack of sheets of material, such as wood pulp, on said support, a wrapper covering the top, sides, and ends of said stack, the central part of said wrapper-being on top of said stack, and the remaining portions of said wrapper embracing with their intermediate parts the sides of said stack, and with their vertical edge portions the ends of said stack, and forming top flaps which also embrace said ends of the stack, and means to secure said vertical edge portions and said 2. A package comprising a support, units consisting of pluralities of sheets of material, such as wood pulp, folded in long and short laps, and arranged on said sup ort and on each other, with the short laps 0 one set of alternate units at one side and the short laps of the other set of alternate units and forming top flaps which also embrace at the opposite side, a Wrapper covering the said ends of the stack, and means to secure 13 top, sides, 213d ends of said stack, the cgntra said vertical edge portions and said flaps. part of sai wrapper eing on top 0 sai Bstack, and the remaining portions of said JOSEPH WOODRUFF' wrapper embracing with their intermediate Witnesses: parts the sides of said stack, and with their F. A. CUTTER, vertical edge portions the ends of said stack, A. G. FAIRBANKS.
