treatment thatreceptacles used for this purpose are subjected to, is necessarily severe, and stringent rules have been established by the railroads as to the character of containers which Will be permitted for this purpose. No container which fails to comply with the requirements ofsuch regulations, areadmitted to the preferred freight rates. Among the tests which such receptacles are submitted to is moisture-test and a crushingtest. Receptacles of fiber board can be best made to meet the moisture-test, by the use of some water-proof compound, while the crushing-test is most economically met by the use of receptacles made up of comparatively thin layers united by an adhesive. According to this invention, the water-proof compound is also the adhesive employed to unite the 'ilurality of layers of the receptacle. The necessity of employment of the adhesive complicates the problem of manu facturing the receptacle, in that the char actor of the receptacle must be such that it may be readily formed in spite of the presence and use of adhesive, while to avoid an expensive plant, it is necessary that it be of such a character that the several layers may be held in place, until the adhesive sets, without demanding the holding of the receptacle in a former during the setting process. The importance of this will appear when it is remembered that to meet thedemands of competition, and reduce the cost of the containers of articles which sell at a comparatively low figure, such a container must be made at a minimum of cost. This is so pronounced that the difference of a small fraction of a cent in the cost of the V Specification of Letters Patent.

container may determine the possibility of its use. p In Patent #926,758, granted to me July 6th, 1909, I have shown and described a receptacle formed by folding a blank which comprises two main parts, each part constituting a bottom and upstanding members, the members of each part of the blank being folded independently of the members of the other part, and the folded members of the onepart inserted within the members of the other, theouter part being provided upon its upstanding members with an interlock which holds the upstanding members of inner parts together and in place.

My present invention contemplates an improvement on themethod of making'up the carton therein described, in that I contemplate applyingto one side of the blank, a suitable adhesive, in folding outer part of the blank prior to folding and inserting the ,inner partof the blank therein, andin utilizing the interlock of the members of the outer part as a means for holding the blank in shape while the adhesive between the outer and inner parts are setting, thus dispensing with the necessity of holding the receptacle in a former during the period of setting the nature of the folds made in the blank, being such that the sides of the blank,.

to which the adhesive is applied not exposed at any point on the inside or outside of the receptacle.

Referring to the accompanying drawings, in which corresponding parts are designated by corresponding marks of reference, Figure 1 shows a plan view of a blank which may be used in carrying out'my process. Fig. 2 is a side view of a completed receptacle, and with parts of the side wall toward the observer, and the left-hand end of the figure removed. Fig. 3 illustrates the blank in the process of formation, the outer hav ing been folded.

The blank which I by preference employ, and which I have shown in the accompanying drawings, is substantially the blank shown inmy said prior patent, except that it is not provided with a cover. It is cut to the general conformation indicated in Fig. 1, and is scored to facilitate folding along the dotted lines 1 to9, inclusive, and out along the continuous lines 14 to 23 inclusive. W'hen thus treated, the blank comprises an inner bottom B and side walls A and A, and end walls 0, connected therewith, the latter having thereon flaps c. It also comprises an outer bottom member. B, ha ving end walls bfiexibly connected therewith, and the side walls D and D terminating in flaps d, d, the latter being each cut through as at o, awhile the former terminate in tongues e, adapted to enter'the slits 0, thus interlocking the flap (l of one side wall with the flap d of the other.

In forming up the receptacle from such a blank, I apply to one side of the blank, a suitable adhesive, and take such blank with the adhesive thereon, and bend up the end flaps I) and the side walls and l), on the side having adhesive, interlocking the tongueupon' one side wall with the corresponding slit 0 in the opposite side wall,

with the end walls 0 interposing between them, thus forms a structure comprising bottom and continuous upstanding members which are locked by the interlocking before mentioned. Theside walls A and A are now folded downwardly or away from the coated side upon the bottom B, and the end flaps a folded around the ends of the" side walls, A, A, after whichthe walls A and D are folded on the scoredline 5 so that the receptacle formed by the upstanding membcr attaehed'thereto is brought'down within the receptacle formedby theibottom B and upstanding members attached thereto. The recepaele thus foldedmay be now inserted for a few seconds on a suitable forming mechanism to expand the inner section against the outer section, which may be held against tearing at this time, this being preferably done by male die in a press and is then removed for the drying of the adhesive. In this drying, the interlock existing between the upstanding member of the outer part holds the receptacle in shape without the necessity of retaining the receptacle within a former.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 2- The hereinbefore described process which consists in cutting a blank, coating one side thereof with an adhesive, bending up parts of the blank to form upstanding members arising from a bottom iasteningsuch upstanding members together, bending the other parts of the blank to fit within and against the fastened upstanding members,

and in then inserting the last named part of the blank within the first named part of the blank, with the coated side of the JAMES B. MILLER, In presence of LAURA PARDEE, Tnos. G. BURKE.
