GLY'DE S. BRA NDENBURG, OF CHICAGO, ILLINOIS PACKAGE 'waarrme msvrcn Applicationfiled March 26,

This invention ,relates to improvements 3 surface extend transversely of the table in devices for wrapping packages and more particularly to a device of this type for wrapping boxes, such as boxes containing thin transparent flexible glasslike substance called cellophane.

To wrap a retangular'box with this thin flexible substance by handmore care is required and more time consumed than wrap- 10 ping the same package with ordinary paper on account, of the nature'of the material. It is an object of this invention to provide a -table'sb constructed and equipped with a treadle operated mechanism to allow an op- 15 erator to wrap a rectangular box partly by hand assisted-by the mechanism, in a more uniform manner and in much less time than if the wrapping were done entirely by hand.

With these. and other objects in view .reference is made to the accompanying sheet of drawings which illustrates a preferred form of this invention with the understand ing that minor detail changes may be made without departing from the scope thereof.

' In the drawings:

Figure 1 is a top plan view of an embodiment of this invention.

Figure 2 is a view in si Fi ure l. W I

igure 3 is a view in end elevation of Figure 1.

While the drawings illustrate the application of this invention as applied to wrappin rectangular boxes of candy, it is to be un erstood that it is not restricted to this use alone. While candy boxes are usually rectangular in shape and vary in size in accordance with, their capacity, a manufacturer .or dealer usually employs uniform sizes and shapes of boxes, that is, a standard length and width varying in depth in, accordance with the desired capacity. This invention contemplates the rovision of a device which may be employe for wrapping such boxes of varying capacities irrespective of their depth. v 1

The embodiment of this invention as ilde elevation of lustrated includes a table 1 supported u on legs 2 and mounting above the table sur ace two spaced apart wrapper supports 3 lying lying 1930. Serial No. 438,932. in the sameplane and parallel to the-table vertical planes with the edges of the 'table 1.

As heretofore stated the materialcalled cellophane is ver as being of glassli e transparency and if a sheet of cellophane were laid upon the wrapping surfaces 3 it would sink down between them and to prevent this occurring a light coil spring 4 is preferably mounted upon the transverse center of the table, or a plurality of suchrsprings if desired are provided which will be engaged by the under side of the sheet and be supported in the same plane with the wrapper supports 3. For the eflicient wrappin of the boxes upon this device, it is pre rableto fold the diagonally opposite corners of the sheet about the width of the box and to insure auniform wrapping in this manner, each table surface 3 is provided with a corner guide 5, as shown in Figure 1.

When a sheet of cellophane is placed upon the wrapping supports 3 with its corners over the longitudinal and transverse lines of the table and its center supported upon the spring 4 the operator grasps the box to be wrapped, places it over the center of the sheet and depresses it between the wrapper supports'3 which, as the sheet passesover the edges of the supports 3, imparts an upward'movement to the corners of the sheet resting upon the supports 3. The operator grasps first one of these corners and then the other and wraps the body of the sheet. about the width of thebox, moistening the under surface of the outer corner and firmly pressing the moistened portion down upon the portion of the sheet thereunder to which it will adhere. 1

To fold-over the portions of the sheetexcenter tending in prolongation of each side of the thin and flexible as well box about the opposite ends, and then fold over the triangu ar portions of the sheet extending in prolongation of the bottom of the box mechanical slides and folding devices are provided-and, as illustrated, include the low the opening between the spaced apart wrapper supports 3.

A treadle operated shaft 9 is mounted for vertical reciprocation'below the center of the table 1 having a treadle 10 arranged to be easily engaged and depressed'by the operators foot to impart a downward movement to the shaft 9. The upper portion of the shaft 9 is provided with means which acts upon the-depression of the treadle 10 to coact with the slides 7 and folders 8 to first cause the oppositely disposed slides to move toward each other engaging the portions of the wrapping sheet extending in. rolongation of the sides of the box and feld them inward toward the end of the box and then cause the folders 8 to move upward about their hinges to fold the triangular portions of the wrapping sheet to fold these portions over the ends of the box outside the side folds In the embodiment of this invention illustrated each sliding member 7 is shown mounted to reciprocate over tracks or bear ings 11- provided by bending over the longitudinal edges of plate 12 mounted between the supports-3 and table 1 on each side of the opening between the supports, 3. Each normally maintained with its member 7 1s engaging nose withdrawn from the opening between the supports 3, as by a spring 13 se- Inents to the sliding member 7 and end foldcured to its exterior end and an extension from thetable 1. The hinged end folding members 8 are preferably each provided with a springpressed plate or fingers 14 mounted upon the same hinge and adapted to first engage the outer surface of the triangular wrapper and the outer free ends of each member are preferably provided with a right angular extension 15 which as the member assumes a vertical position will en-' gage the outer free triangular portion and impart a movement to its corner in the direction of the center of the box.

While any desired means may be employed to impart the above described moveing members 8 the drawings illustrate a rectangular frame 16 mounted upon the shaft 9 adjacent the under side of the table 1 provided with oppositely disposed sets'of cams l7 and 18, one set 17 adapted to cooperate with pivotally mountedt arms 19 adapted upon depression of the shaft 9 to recipro-' support t shown.

The operator having placed the box to be wrapped upon the table and secured the corners of "the sheet wrapped about the sides of the box, then depresses the foot treadle 10 which first folds in the sides and then the triangular ends of the sheet. The operator then completes. the fold of the triangular ends by grasping a corner and folding it down upon the top of the box and preferably securing the same by the application of a gummed sticker which may be taken from a receptacle 21 carried on the table support 3 and moistened by a sponge likewise carried in a receptacle 22 adjacent receptacle 21. Having secured each of the triangular end folds, the foot treadle 10 is released, the side and end folding members are retracted, the box removed, and the spring 4 extends to normal-with its upper end in the same plane with that of the wrapper supports 3. It might be said here that the spring or springs 4 are onl of sufficient power or strength to he center of the light sheet of cellophane wrapper. P

It has been found that by the use of this device a single operator is able to wrap four times as many boxes-during a given time than can be wrapped by hand.

What I claim is:
