FACTURING COMPANY, SACHUSETTS or woaonsrnn, arassacnusnrrs, assreivon ,ci o noens Mantior wononsrnn, MASSACHUSETTS, A CORPORATION or MAS-V CORNER-CUTTING MACHINE Application filed July 13, 1929. Serial No. 378,017.-

This invention relates to a machine particularly designed for cutting corner pieces from box cover papers. Such machines are provided with cutting dies which must be changed from time to time to correspond to the particular piece of work being handled.

It is the general object of my. invention to provide an improved construction for supporting the dies in a corner cutting machine,

10 by the use of which the cost of dies is greatly reduced and by which the changing of dies is facilitated.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claim.

A preferred form of the invention is shown in the drawings in which Fig. 1 is a side elevation, partly in section, of certain parts of a corner cutting machine;

Fig. 2 is a partial plan view of a product of the machine;

Fig. 3 is a plan view of the lower die and the base therefor;

Fig. 4 is a side elevation, looking in the direction of the arrow 1 in Fig. 3; V

Fig. 5 is a sectional side elevation, taken along the line 55 in Fig. 3;

Fig. 6 is a plan view of the lower die base; and

Fig. 7 is a detail front elevation, looking in the direction of the arrow 7 in Fig. 1.

Referring to the drawings, I have shown a port-ion of the frame 10 of a corner cutting machine. The frame includes a bed 12 on which the lower die or cutter is mounted, and an upwardly projecting post or support 14 in which the head 15 of an upper die holder 16 is slidable. The head 15 and holder 16 are preferably made as separable parts, so that the holder 16 may be removed and replaced without removing the head 15. Suitable operating mechanism (not shown) is provided for raising and lowering the shank 15 and upper die holder 16.

The machine is designed particularlyfor cuttin out the corner pieces of papers used for covering boxes or for other similar purposes, an example of the work being indicated in Fig. 2, in which the blank B has been out along the lines 17 and 18 and has also been provided witha notch 19. r

A support or stand 20 is slidably mounted in guideways 21 in the? bed 12 and may be.

transversely adjusted on the bed 12 by an adjusting screw 22 shown in section in Fig. 1'.

'1 he support 20 has an upwardly projecting portion 2 1, preferably forme'dintegral therewith, which is provided with guideways for a guide member 26 projecting laterally from the upper die holder 16.

A. rectangular hollow die base 30 6) is firmly secured to the support or 'stand 20 by binding screws 82. A die bar 33 is secured to one end of; the base 30 by screws 34: and a second die bar 36 is secured to the top of the base 30 by screws 37. The screws 37 extend through slots 88 in the bar 36, thus permitting endwise adjustment of the same after regrinding, it being essential that the end oi the die bar 36 closely abut the side of the die bar 33. Cooperating die bars 40 are mounted on the upper die holder 16.

It will be seen that the base 30, together with the

die bars

33 and 36, constitute a single structure which may be conveniently inserted in the machine or removed therefrom as a unit, and which is secured to the stand or support 20 by the removable screws 32.

When it is necessary to change the work in the machine, it is accordingly required simply to remove the base 30 and the die holder 16, with their attached die bars from the machine, and to replace the same by a base and holder having dies or knife bars of the desired contour. This operation is simply and easily performed and the parts are simple and relatively inexpensive.

Having thus described my invention and the advantages thereof, 1 do not wish to be limitedto the details herein disclosed, otherwise than set forth in the claim, but what I claim is A corner cutting machine comp ising a frame having a bed, and an upwardly projecting post, a base support slidably adjus able on said bed and having an upwardly projecting portion, an upper die holder having a lateral member slidable in a guideway in said upwardly projecting support portion, a

7 die holdef head slidable in a guideway in said frame post and de ta chably secured to said die holder die" bars for said holder, a lowe r die 1 comprlsing a rebfiarigular hollow base and die balr'sfscured thereto, and means to detachably 'secul e said' re ct a ngular hollow base to said shdlngsupport.

.In testimony .whereof I have hereunto aflixed my signature.

I GEORGE *KLAUCKE.
