To all whom it may concern:

Be it known that I, I'IENRY L. PLUMMER, a. citizen of the United States, residing at letersburg, in the county of Dinwiddie and State of Virginia, have invented certain new and useful Improvements in Machines for Cutting and Preparing Dress-Suit-Case Body-Blanks; and I. do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apertains to make and use the same.

This invention relates to improvements in machines for cutting, punching and creasing paper blanks or sheets, and especially to a machine designed for preparing the body blanks of dress suit cases.

Some types of dress-suit cases are provided with a substantial card board body or inner liner which is ordinarily cut to approximately a given size and contour, and the present invention provides a machine for treating this previously cut blank for forming the body so as to facilitate the bending of the main panels thereof to form a side and longitudinal parallel components of the body.

In the present case the type of suit case for which the blanks are cut is provided with a cardboard sheet or body member which is lined previously to be finally out, punched and creased on one side with a suitable trimming and finishing sheet of material, and the present invention has for its object to simpltaneously cut the trim' ming sheet to the desired outline and to punch and crease the principal or body forming card along such lines and at such positions as will facilitate the folding of the several panel and edge or corner forming areas, an especial object of the invention being to provide a machine that will operate effectually and which will permit the rapid insertion and proper registration of the blank to be cut and which will produce accurately cut and completely finished blanks.

With the above and other objects in view 7 as will be readily manifest to those skilled in the art, the invention consists of the c0nstruction, the combination, and in details and arrangement of the parts as more particularly described hereinafter relative to the embodiment of the invention disclosed in the accompanying drawings, wherein:

Figure 1 is a plan view of the body blank with its cover sheet previously to being out 1n the machine forming the subject matter of the present application.

Fig. 2 is a plan view of the completed blank.

Fig. 3 is a perspective view of the main or body blank folded ready to be installed or assembled in the process of manufacturing the box of the dress suit case.

Fig. 4 is a vertical longitudinal section through an embodiment of the invention.

Fig. 5 is a plan view of the lower die, the pins being shown in section on line 5-5 of Fig. 4.

Fig. 6 is a detail plan view in section of She guide pins, the punch and the creasing les.

Fig. 7 is an enlarged detail view of the corrugating and creasing dies.

Fig. 8 is a plan View of a-fragment of the lower die showing the guide pins in section and indicating in dotted lines the position of an adjusted blank.

In Fig. 1 the main body formin card of the dress suit box is indicated at it havmg been cut to the required size and given the desired formation by any suitable apparatus and method, and being indicated as having a pair of parallel edges V-notched as at 2 to facilitate the folding of the blank C to the position shown in Fig. 3.

The edges of the V-notches meet to form the joint 4 between the edge flanges 5.

The corners of the body blank are also peculiarly cut away or notched out, as at 6, to produce the desired finish of the corners of the parallel side members (i -6 inFig. 3.

In the method that I follow in the manufacture of this type of box there is applied to the back of the blank or card C in Fig. 1 a suitable strip or sheet of paper or other suitable material of the desired properties, this being indicated as forming a binder B of generally longer area than the card or blank C, as plainly shown in Fig. 1, it being notched at 77 complementary to the notches 2 of the card so as to facilitate folding and eliminate any crinkling at the inwardly folded joints 4.

My present improvements are designed to facilitate the manufacture or production of larly corrugated alon parallel lines near the edge and perpen icular to the lines 8.

Further, the edges of the card C are grooved and are score lined along lines lit-10 parallel to the corrugations 9 -9, the deep corrugations 8 and 9 facilitating the bending of the card with the respective portions at right angles to each other, such deep corrugations being clearly shown 1n Fig. 7, while the lesser score lines facilitate the bending of the lips 1111 inFig. 3, these lips bein bent over but a relatively slight degree from the plane of the side panels 6-6.

For the purpose of enabling the blanks to be rapidly inserted in a machine andpunched, out and creased in one operation, I have provided a machine including any suitable platen or table, indicated at T on wlnch is arranged a lower die structure 13 of any suitable form of construction and above the die 13 there is arranged a reciprocating head 14 on which is arranged an upper or male die structure 15 complementary to the die 13.

The lower die is shown as provided with apertures 16 here shown as formed in bushings 17, preferably of hard material, to serve as counter cutters cooperating with punches 18 forming a part of the upper die 15. The punches at the rear of the head 14 are shown as provided with eccentrically arranged and downwardly extending guide pins 19, the pins and punches being designed to pass downwardly into the openings" 16. When the punch head 14 ascends to the uppermost position of the punch head the pins 19 are still extended into the apertures 16 in the die 13 and the operator has but to push the blank B-C over the lower die 13 until the V-notches 2-2 at the opposite edge encounter the guide pins 19, whereupon the latter will serve to automatically guide the blank to its proper position upon the lower die 13.

Thereupon, while the upper die 15 attached to the punch head 14 is caused to move downwardly, the punches 18 will pass through the blank to be punched and enter the holes 16. Immediately following or approximately at the same time of the operation of the punches 18 corrugating blades 20 forming a part of the upper die 15 will engage the upper surface of the inserted card or blank and depress or corrugate the same by forcing it downwardly into complementary channels or grooves 21 formed to register therewith in the upper face of the die 13.

Following the corrugating step closely, suitable creasing dies or blades 22 forming a part of the upper die 15 engage the upper face of the card being operated upon and indents or compresses the card to a suitable degree, thus forming the marginal creases 10-1O in Fig. 2.

in opposition to these knives I prefer to em-.

ploy wooden or other soft material blocks 26 suitably connected to the die 13 to take the impression of the cutter edges and thereby protect the same against injury.

These blocks 26 are shown in Fig. 5 as being removable and held in place by clamps 27 so that as the blocks become unduly worn they may be disconnected and others inserted in their stead.

After the above described punching, corrugating and creasing steps have been completed the plunger head 14 ascends and in order to eject or strip the car BC from the plungers any suitable stripping device may be employed, it being shown as comprising, in the present case, a plate 28 mounted on the lower ends of the carrying pins 29 which are slidably mounted in the punch head 14 and are automatically pressed downwardly by ejector springs 30 surrounding the pins 29. In the uppermost position of the plunger head 14 the plate 28 is sufliciently elevated above the face of the die 13 to enable the operator to readily insert the card B-C to be punched into position. this being guided as in the manner above described by the guide pins to their proper location.

\Vhat I claim as new and desire to secure by Letters Patent, is:
