4 Claims.

This invention relates to an apparatus for punching previously cut portions from cartons such as chick cartons and the like.

It is well known that various cartons are manufactured with a plurality of perforations therein for various purposes such as to permit air to flow into the interior of the cartons when the carton contains animals such as baby chicks and the like. In manufacturing cartons of this type, the perforations are cut in the stock forming the carton, and the cut-out portion usually adheres to the stock due to the fact that the cutting machine does not punch it out, or in some instances a small portion isnot cut away. Heretofore, it has been necessary to punch these outout portions from the stock or from the assembled carton by hand and this has been a tedious and expensive operation.

It is therefore an object of this invention to provide an apparatus adapted to receive a container such as a cardboard carton which has previously been cut to form a plurality of perforations, the cut-away portions still adhering to the carton, and said apparatus being so constructed as to engage the carton on all sides thereof and being provided with projections adapted to coincide with the cut-out portions of the carton and having means causing said projections to move into striking engagement with the cut-out portions to remove the same from the carton.

It is another object of this invention to provide an apparatus of the type described having a planar bottom member and being provided with hinged portions on each side and each end thereof adapted to be moved into a vertical plane to engage the vertical surfaces of a cardboard container resting on the planar surface and said apparatus also being provided with a support member extending upwardly from the planar support member and having a lever pivotally mounted thereon to which a plate is secured, said plate and said hinged side and end members all being provided with a plurality of projections adapted to coincide with the cut-out portions of the container, and said lever having the plate thereon also being provided with a spring normally holding the plate out of engagement with the top of the carton and handle means adapted to be seized by an operator for moving the lever downwardly so that the plate will engage the top of the carton member to cause the projections thereon to punch out any cut-away pieces of cardboard still adhering to the top of the carton, and to also move the side members to vertical position.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which- Figure l is an isometric view of the apparatus showing the same in open position and showing a carton associated therewith, portions of the ctarton being broken away for purposes of clar- 1 V;

Figure 2 is a top plan view of the apparatus in closed position;

' Figure 3 is a side elevation of the apparatus in closed position; t

Figure 4 is a vertical sectional view taken along the line 44 in Figure 2;

Figure 5 is a vertical sectional view taken substantially along the line 5--5 in Figure 2.

Referring more specifically to the drawings, the numeral N] indicates a suitable table on which the apparatus may be disposed if desired. The apparatus comprises a base in the form of a planar member H which is preferably rectangular in plan and which may be the top of a suitable table ID, if desired, and which has secured thereto side guide members l2 and I3 and end guide members [5 and It. The guide members l2, l3, l5 and i6 are disposed in a horizontal plane and the end guide member has a vertically disposed end punching member lfia secured thereto and held in position by brace members l8, I9, and 2! secured to the end guide member l6 and to the end punching member lfia.

A side punching member is hingedly secured as at 26 to the upper surface of the side guide member I2 and a second side punching member 21 is hingedly secured as at 28 to the upper surface of the side guide member [3. An end punching member 33 is hingedly secured as at 3! to the upper surface of the end guide mem ber l5 and this member 35 is provided with a handle 32 for raising the same to a vertical position.

Support members comprising a pair of uprising posts 35 and 36 are suitably secured at their lower ends to the upper surface of the end guide member It at a point intermediate the ends thereof. A lever 3'! is pivotally secured as at 38 between the uprising posts 35 and 33 and the lever 31 extends longitudinally of the apparatus for a distance substantially equal to the length of the planar member H and is provided with a handle 40 at the end thereof remote from the pivot point 38.

An upper punching member or plate 4| is secured to the lower surface of the lever 31. The

plate 4| may be of any suitable construction and is shown as comprising four separate members 42 to 45, inclusive, all being disposed in the same plane and being secured together by means of longitudinal ribs 41 to 50, inclusive. A pair of transverse ribs 52 and 53 extend across the top of the ribs 41 to 50, inclusive, and secure the same together to thus form the plate 4|.

The lower surface of the lever 31 is cut away as at 55 and the upper surface of the transverse rib 53 fits into this cut away portion. A spacer block 56 is secured to the lower surface of the lever 31, intermediate the transverse ribs 52 and 53, as by a bolt 51, and the plate 4| is secured to the lower surface of the spacer block 56 as by bolts 6|] and BI.

It will be observed in Figures 1, 3 and 4, that this will cause the plate 4| to be disposed at a slight angle relative to the lever 31 and the upper surface of the transverse rib 52 will not be in engagement with the lower surface of the lever 31. The purpose of this is to cause the plate 4| to be in an almost horizontal position at the time it engages the upper surface of a carton to be described.

The end of the lever 31 remote from the handle 40 extends beyond the support members 35 and 36 and is cut away as at 65 and a transverse member 66, of any suitable material such as strap iron, is secured thereto. The transverse member 65 extends on each side of the lever 31 and has pivotally secured to each end thereof depending links 61 and 68, respectively, the lower ends of which are pivotally secured to the ends of the side punching members 25 and 21, respectively. 1

A brace member 1|] is also secured to the upper surface of the lever 31 and to the rear surface of the transverse strap member 66 to hold the same securely in position. A suitable tension spring 1| is secured at its upper end to a spring anchor 12' disposed on the end of the lever 31 remote from the handle 40 and the other end of the spring 1| is secured to a suitable spring anchor 13 disposed on the upper surface of the planar member II.

A plurality of projections 80 are suitably secured to or embedded in the proximate surfaces of the side punching members 25 and 21 and also to the end punching members 30 and Mia, and a plurality of these projections 80 are also suitably secured to or embedded in the lower surface of the members 42 to 45, inclusive, comprising the upper punching plate 4|. These projections 80 may be spaced in any suitable arrangement, and are provided to engage cut-away portions of a cardboard carton broadly indicated at 8| in which a plurality of portions 82 have previously been cut.

The carton 8| may be of any suitable construction and the drawings show a carton of the type which is frequently used for containing baby chicks and the like and which must have a plurality of perforations in the side and top walls to permit the chicks contained therein to obtain air. These perforations are usually out in the cardboard stock by a stamping or cutting machine which frequently fails to cut the disks forming the perforations completely free from the carton. The disks forming the perforations may be of any suitable shape and may be spaced as desired. When the disks 82 are out completely free from the carton they will usually adhere to the carton requiring an operator to punch the same free from the carton to form the perforations.

Now, it will be observed that the carton 8| may be placed with its lower surface resting on the upper surface of the planar member H and one end of the carton may be moved adjacent the guide member 16 to cause the projections on the end punching member |6a to engage the disks 82 in the end wall of the carton and punch the same free from the carton. Then the handle 40 may be grasped by an operator and pulled downwardly causing the plate member 40 to engage the upper surface of the carton 8| and as the end of the lever 31 remote from the handle 40 moves upwardly around the pivot point 38, the strap member 66 and the links 61 and 68 will cause the side members .25 and 21 to be moved to a vertical position to cause the projections 80 thereon to engage the disks 82 in the side walls of the container. The handle 32 may then be raised causing the end punching member 30 to be moved to a vertical position so that the projections 80 thereon will punch the disks 82 outof the other end of the carton 8|.

The handle 32 may then be lowered to move the end punching member 36 to a horizontal position and the handle 40 may be released which will cause the spring 1| to urge the end of the lever 31 remote from the handle 40 downwardly to raise the plate 4| with its projections 80 from the top of the carton 8|. The arms 61 and 68 will be urged in opposite directions to move the side punching members '25 and 21 to a horizontal position and then the carton may be removed from the apparatus.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
