PAPER BOX.

SPECIFICATION forming part Of Letters Patent NO. 476,661, dated T une 7, 1892.

Application filed February 11, 1892. Serial No. 421,118. (No model.)

To @ZZ whom t may concern:

Be it known that I, PHILIP L1NDEMEYEE,a resident of Baltimore, in the State ot' Maryland, have 'invented certain new and useful Improvements in Paper Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to the covering or wrapping of boxes, and has for its object to provide means for applying covers or wrappers to boxes with greater'accuracy, rapidity, and economy than heretofore attained; and it consists in the improvements hereinafter described and particularly pointed out.

In the accompanying drawings, Figure l is a plan of a flattened or partially-formed tube suitable for making three boxes and having a cover partially broken away. Figs. 2 and 3 are enlarged sections on lines x rc and .e e, respectively, of Fig. l; and Fig. et is an enlarged section on the same plane as Fig. 3 after the flattened tube has been brought into strictly tubular form.

It is customary to make paperboard boxes from sections of a rectangular tube. The board is first marked, out, bent, and pasted to form what may for convenience be called a tube-blank or liattened'tube as indicated in Figs. l and 2, in which the spaces inclosed between the lines marked l and 2 indicate portions of a board adapted to constitute sides of a box when formed and spaces included between the lines 2, 4, and 3 indicate portions adapted to be folded at right angles to the said sides to form the en ds of the boxes. The lines 4E also indicate slits in the board of which the tube is made, and the lines 3 indicate where the tube-blank is out to separate the sections that are to be formed into boxes. Irappers or covering-labels are usually applied to the sections after they have been opened or made to assume a tubular form by pressing the sectional tube-blank at its edges and forcing the several sides to assume an angular position with respect to each other, as indicated in Fig. l. The wrapper, being cut to the proper size, is covered with paste upon one side and wrapped about the tube, which is generally placed upon the pasted wrapper and turned over upon it three or four times until it adheres to the entire surface of the short tube. @ne end of the box is then closed by folding the slitted end portions of the board at right angles to the sides and then folding upon it the corresponding part of the wrapper, whereupon the box is filled and the other end closed in like manner. According to this customary method the wrappers are applied to the boxes singly and only after the sections of the tube-blank have been brought into strictly tubular form, as by compressing the tube-blank edgewise, as it would be impracticable to first apply the wrapper for the reason that the tube could not be formed from a tubeblank after the application to its entire surface of a pasted wrapper` without injury to the latter.

Both skill and time are required to properly apply a wrapper to a single box and so that it shall not be awry, and, besides, an objectionable quantity of paste or other adhesive is necessarilyemployed. To avoid these objections I first provide a wrapper equal in length to the tube-blank-such as indicated in Fig. l of the drawings-and suitable for forming two, three, or more boxes and of such width that it will inclose the said blank cir-v cumferentially and its edges overlap, so as to permit them to be pasted together and the wrapper thereby secured upon the blank. Printed matter can, if desired, be put on the wrapper before it is thus applied to the tubeblank and so that each box,when completed, will be provided with any desired label on its sides and ends.

Preferably each portion or section of the wrapper is made to adhere to one or more sides of the box in some convenient manner, as by a small quantity of adhesive applied to the saine or to the corresponding portion of the wrapper, to prevent slipping of the subsequently-formed sections ofv wrapper and tube with reference to each other during the final folding operation. It is important that the method of fastening shall be such as not to interfere with the formation of tubes from the tube-blank sections, as above described. The wrapper is by preference so placed upon the tube-blank that its overlapping edges or Seam shall not be adjacent to the overlapping edges of the tube-blank to avoid all danger in the completed article of leaking through the joints ot' both in case of accidental fault of manufacture-as, for example, if the sliti be made in any case to extend backward beyond the end of the box-that is, towardV its body beyond the bending-line 2 of the end. The entire Wrapper having been applied to the tube-blank is, together with said blank,v

out into sections on the line 3 of the former and line 3 of the latter. The covered flat tube-blank sections thus produced are com pressed edgewise to form tubes, whereupon` one end of each is closed, the box filled, and its opposite end also closed, as before set forth.

In applying the Wrapper to thetu-be-blankby the present method but two foldings of the Wrapper are required instead of four, as formerly, and the series.v of connected wrap? persicorresponding to a considerable'series of boxes-can be'a'pplied as quickly or quicker than a single Wrapper to a tube by the old method andv with greater accuracy, first, be cause the corresponding lines oflthe Wrapper and Hat tube-blank are longer and present a better guide to the eye' than in caseof a sin-4 gle Wrapper and short tube, and, secondly,

because any error which may occur in placing' the long fiatA tube-blank and its wrapper together isI distributed throughout the series and is thereby made small for each box.V The Separate cutting of theWrapper-blank to make j specification-in the presence ot' two subscribing Witnesses.

individual Wrappers is obviated, this being effected by the same operation? which cutsthe tube-blank into series.

I am aware that two strips ot paper have I duced and a longitudinal edge ot eachstrip subsequently pasted, and that the double stri p thus produced has been formed into a iiattened tube and then transversely severed one by one into bag-sections along the first-named pasted lines, the strips being drawn length- Wise through astrip-pasting and tube-forming `machine, and such mode of procedure is not of my invention.

Having thus described my invention, what I desire to secure by Letters Patent isl. The improvelnent in the art of making covered boxes, which consists in slitting strips of paper at intervals lengthwise preparatory toprodu'cing thel box ends, forming the tubeblank or attened tube adapted to make Several boxes, applying. to said tube aiwrapper,

simultaneously cutting said Wrapper and the tube'into sections across the slitted portion Y ofthe' latter, changing. said sections-into tubu lai` form, and closing their-ends, substantially as set forth.

2. Theimprovem'ent in'vthe'a'r't of making covered boxes,-which consists informing the f tube-blank or flattened tube adapted to' make several boxes and in applying.. to said tube a Wrapper, securing the Wrapper to parts of the i tubc-blank*corresponding to sides of the boxes when completed, simultaneously cutting the vtube and its Wrapperinto4 sections,changing said sections into tubular form, andl closing their ends, substantially as set forth.

In testimony Whereot' I have signed this PHILIP LINDEMEYER.
