MACHINE FOR WRAPPING PACKAGES Filed Dec. 26. 1930 2 Sheets-Sheet 2 Even Z 01".- John Z/z' afar/V6! 5071 Patented Apr. 25, 1933 UNITED STATES PATET OFFICE JOHN VICTOR NELSON, OF CHICAGO, ILLINOIS,

OF DELAWARE MACHINE FOR WRAPPING PACKAGES Application filed December 26, 1930. Serial No. 504,817.

This invention relates to machines for wrapping packages, and it has for its object providing a very simple and effective machine for the purpose which is readily applicable to packages of various sizes and which can be quickly adjusted for use in wrapping packages of various dimensions and thicknesses. Another object is to provide a machine that can be manipulated by operators with little skill without liability of injury. Other objects of the invention will be apparent from a consideration of the accompanying drawings and the following description thereof:

Of the drawings, Fig. 1 is an elevation of the machine, embodying the features of my invention; Fig. 2 is a plan view thereof; Fig. 3 is an enlarged fractional plan view;

Fig. 4 is a sectional view along the line 44 20 of Fig. 3; Fig. 5 is an elevation along the line 55 of Fig. 3; Fig. 6 is a plan view of the member 39; Fig. 7 is an enlarged sectional View along the line 7-7 of Figs. 1 and 8; Fig. 8 is a sectional view along the line 88 of Fig. 7; Fig. 9 is a sectional view along the line 9-9 of Fig. 7; and Figs. 10 and 11 are enlarged views of a portion of one of the operating members of the machine.

The machine provides for a supporting plate upon which the wrapper of the package is laid, with the goods to be wrapped lying on the wrapper, and for means for turning up two opposite sides of the wrapper and then for turning up the two other sides of the wrapper. The four wrapper sides are then projecting upwardly and the operator then completes the wrapping and 40 the binding together in any desired manner. The machine comprises a frame 15 supporting a top plate 16. On this plate are mounted blocks 17 and 18 which support the outer and inner ends of rods 20. The top plate also supports blocks 21 which are arranged to support rods 22 which extend from one block 21 to the other. Upon each pair of these rods 20 and 22 are slidably mounted similar frames 23, and pivoted to each of the frames 23 is a wing 24.

In operation, the wrapper is placed on a table 25, and the goods to be wrapped are placed on the wrapper over the table. The edges or the corners of the wrapper project over the wings 24. When thus arranged, two of the opposite wings 24 are rotated upwardly in a manner hereinafter described, and then the other two opposite wings are rotated correspondingly, holding the sides of the wrapper upwardly, and the operator then completes the wrapping of the package in any suitable manner.

The means for operating the wings comprise a foot lever 30 pivoted to the lower side of the frame. Pivoted to the central ASSIGNOR, BY MESNE ASSIGNMENTS, TO F portion of the lever are links 31 which are pivoted to opposite sides of a shank 32. The shank 32 projects downwardly from a cam member 33. As this member is forced downwardly, the cam surfaces 34 operate the inner ends of levers 35. Fixed to the outer ends 36 of each of these levers is pivoted a sleeve 37 which encircles a rod 38. The sleeve is slidably mounted on the rod and is prevented from passing off of the lower end thereof by means of lock-nuts 40 which form stops for the sleeve, and a compression spring 41, positioned between the sleeve and a stop collar 42 fixed to the rod 38, tends to force the sleeve downwardly against the nuts. The upper end of the rods 38 pass through slots 19 and are pivoted to the wings 24. The inner ends of the arms 43 of one pair of levers 35 are higher than the corresponding ends of the arms 44 of the other pa1r.

As the operator presses down on the lever 30, forcing downwardly the cam 33, the arms 43 of one pair of levers 35 are operated, and the corresponding rods 38 are forced upwardly. This results in rotating the corresponding wings 24 from the horizontal position to a vertical position, carrying with them the corresponding edges or corners of the wrapper. The cam member then, continuing to descend, the other cam 9 surfaces operate on the arms 44 of the other two levers 35 and force upwardly the other two corresponding rods 38 and, thus, rotate the other two wings from the horizontal to the vertical position. 1

The inner ends of the levers 35 are pivoted to a disk 39 fixed to the frame, and the cam member 33 is guided by this disk. When the operator releases the lever 30, the cam member 38 is pulled upwardly by the spring 47, the upper end of the spring being connected with the frame by a rod as.

In order to adjust the apparatus for packages of various sizes, the frames 23 may be slid on the rods 20 and 22 to any desired position. The frames are fixed to the rods by means of a screw 45 threaded into the frame and operate against'a ball 47 which coacts with the adjacent ends of pins as. The pins are slidably mounted in the frames 23 and the outer ends of the pins are in contact with the rods 20 or 22. As the inner ends of the pins are bevelled, when the screw 45 is screwed inwardly, the ball forces the pins outwardly against the rods, thus holding the frames firmly in position on the rods. To adjust the frame to a new position, it is necessary only to unscrew the screw 45 slightly and release the pins and slide the frame to the position desired. In this manner, all four of the frames may be very quickly adjusted to the new positions and again rigidly fired to the rods.

The table 25 and also the wings 24 may be of any suitable size, but in order to adapt the machine to very small packages, a table is provided suitable for the smallest packages and, if it is desired to wrap packages which are not conveniently manipulated by the small table, a larger table may be applied. Also, the wings, are made suitable for the smallest packages and, if desired, larger wings may be provided by attaching to the wings 24: extensions 46, Fig. 5, indicated by the dotted lines.

In adjusting the machine for various sized packages, the rods 38 may be vertical or inclined, and, hence, the effective lengths.

of these rods need to be varied. The length of the rods is made ample for the most inclined positions, and for other positions the spring 41 yields when the rods are forced upwardly, thus allowing the excess length of the rods to pass down below the sleeves 37. Fig. 10 illustrates this action, and Fig. 11 illustrates the effect with the inclined rods.

I claim as my invention:

1. A wrapping machine comprising a frame, a table mounted on said frame adapted to support a wrapper and the goods to be wrapped, folding wing supporting members mounted on said frame for horizontal adjustment toward or from each other to adapt the spacing of the wings to different size packages, a plurality of folding wings pivoted on the supporting members, means for rotating said wings to vertical positions,
