CHARLES I. PRESTON, OF MAMARONECK, NEW YORK, ASSIG-NOR TO JACQUES BENDIEN, OF NEW YORK, N. Y.

PROCESS FOR MAKING CONTAZIINERS.

Application filed April 5,

To all whom it may concern:

Be it known that I, CHARLES F. PRESTON, a citizen of the United States, residin in the city of Mamaroneck, county of Westchester and State of New York, have invented certain new and useful Improvements in Processes for Makin Containers, of which the following is a in 1, clear, and exact specification.

My invention relates to a process for the roduction of containers, and refers articuarly to containers having a separab e cover.

In the production ofcontamers, such as boxes, it is desirable that the cover exactly fit the bottom portion of the container and that it be maintained from horizontal movement by means of an interior flange, or neck.

The production of the cover independently of the production of the bottom portion of the container introduces the uncertainty of exact fitment between the two.

*It is evident that if such a container be made with its sides, top and bottom aflixed to each other and it then be sawed toseparate a portion to form a top, that there will be no interior neck to prevent a horizontal movement of the cover, and hence, such a flange, or neck, must be aflixed to the interior sides of the container, thus incurring additional expense and roducing a container in which the neck is not an integral art of the sides, a form of construction of decreased strength over that in which the neck and sides are integral.

All of the above, and other, difiiculties are overcome by the process of my invention by which I produce a container, free from all metal fastenings, if desired, by means of a single sawing process, the resulting container having an absolutely perfectly fitting cover, held from horizontal movement by a flange, or neck, which is an integral part of the container and not a separate part aflixed thereto.

The following of my process is indicated in the accompanyin drawings, in which similar parts are designated by similar numerals.

Figure 1 is a perspective view of one form of device produced by my process.

Fig. 2 is a section through the line 22 of Fig. 1.

Specification 01 Letters Patent.

1921. Serial No. 458,761.

Fig. 4 is a perspective view showing the method of introducing the top and bottom members.

Fig. 5 is a broken vertical section showing a device at an intermediate step of the process.

Fig. 6 is a top plan view of the bottom portion with the cover removed.

Fig. 7 is a top plan view of the process of the underside of the cover.

-In the followin of my process, the two wooden side mo dings 10, 10 and the wooden end molding 11 are fastened to gether by the wooden dowels 12, 12. Each side 10 and the end 11 has a series of internal recesses, or grooves, 13, 14, 15 and an exterior recess, or groove, 16. The top 17 is then placed within the grooves 13, 13, 13 and the bottom 18 is placed within the grooves 15, 15, 15. When the top 17 and the bottom 18 are thus positioned, the end 19 is attached to the two sides 10, 10 by the dowels 20, 20, the top 17 fitting into a roove 13 of the end 19 and the bottom 18 fitting into a groove 15 of the end 19, corresponding to the grooves 13 and 15 of the sides 10, 10 and other end 11. The device, as thus formed, consists of the two sides 10, 10, the ends 11, 19, the top 17 and the bottom 18 all held together by the dowels 12, 12, 20, 20, and hence, can not be opened without dismembering the parts. A cross-section of the upper portion of the device, as thus formed, is shown in Fig. 5. The sides and ends of the device are then sawedcompletely through directly above the grooves 16, 16, 16, 16 and as indicated by the broken lines 21, 21, thus eliminating the portion 22, 22 of the sides and ends. The upper portion of the device, represented by 10, 10 11 19, carrying the top 17, is thus separated from the remainder of the device, forming a lid, or cover, the lower face of the ortions 10 10 11 19 falling down and tting upon the upper faces ot the portions 10, 10, 11, 19 and the extended portions 10 10 11 19 of the members 10, 10, 11, 19 act as a flange, or neck, for the cover maintaining it from horizontal displacement. The finished device is shown in ig. 2, in which the cover is shown as resting upon the lower portion of the container and held in horlzontal position by the extended portions 10, 10 of the lower portion. F or the sake of convenience and appearance, legs 23, 23, 28, 23 are fixed to the corners of the bottom of the container.

Curved moldings have been used for the sides and ends of the illustrated container, but it is evident that plain or other shaped members may be used for this purpose.

It is to be noted that by my process of production exactly fitting contact is made between the cover and the lower portion of the container, between the cover and the flange, or neck, and that the flange, orneck, is an integral part of the lower portion of the container.

It is to be further noted that my process of construction is simple, rapid and economical, in that it comprises fastening three sides to each other, introducing the top and bottom, fastening the fourth side thereto and performing one sawing operation, thus requiring but four fastening means and allowing of the employment of cheaply produced moldings of varied forms to produce attractive results without the necessity of further operations.

I do not limit myself to the particular size, shape, number or arrangement of parts, nor to the particular materials shown and described, all or" which may be varied without going beyond the scope of my invention as shown, described and claimed.

What I claim is:

1. A process for producing a container having a neck for retaining the cover from horizontal movement which comprises assembling three sides of the container, each side having two upper grooves and a lower groove within its inwardly exposed face and groove, fixedly attaching a fourth similarly termed side to produce a container and div-iding the container into two parts between the lower up 301 inward groove and. the upper outward groove.

2. A process for producing a container having a neck for retaining the cover from horizontal movement which comprises assembling three sides of the container, each side having two upper grooves and a lower groove within its inwardly exposed face and an upper groove within its outwardly exposed face below the lower upper inward groove, inserting a top member within the uppermost upper inward groove, inserting a bottom member within the lower inward groove, fixedly attaching a fourth similarly formed side to produce a container and dividing the container into an upper cover portion and a lower body portion in such a manner that an upwardly extended neck will be formed upon the body portion to lit within the cover and retain it from horizontal movement.

3. A process of producing a container and cover which consists in providing a closed unified container so shaped and s0 cutting it that a body with a neck and a cover within which the neck fits are produced.

Signed at Mamaroneck, in the county of Vestchester and State of New York, this 30th day of March, 1921.
