Filed May 23, 1962, Ser. No. 197,828 8 Ciaims. (Cl. 269-315) This invention relates to indexing means and more particularly to die press stops used in indexing stock in a die press for creasing and/or cutting the stock.

At this time the present invention inds its widest use in die presses. In such cases a steel rule cutting and/or creasing die is held in a chase anchored to the base plate of the press. Then the stock, e.g., a sheet of cardboard or leather, is located on the press platen. By closing the platen against the base-held die, the stock is shaped and creased as desired.

Previously it has been the practice to index the stock on the platen by means of small wooden blocks which are glued or otherwise anchored to the press. Such wooden die press stocks have the disadvantage that they are time consuming to make and apply. Further they are versatile and therefore, are quite often custom made for the particular stock with which they are to be used.

The wooden die stocks have an additional disadvantage that the stock will not slide freely against them, and therefore it is necessary to wax such stocks before use. The time consumed in such waxing adds to the cost of operation.

Accordingly it is a major object of this invention to provide improved indexing means.

Another object of this invention is to provide an improved low cost die press stop.

A further object of this invention is to provide a versatile die press stop.

Still another object of this invention is to provide a die press stop which can be inexpensively manufactured of long lasting plastic.

A still further object of this invention is to provide an improved die press stop having a removable lip for retaining stock adjacent the platen.

It is another object of this invention to provide a die press stop which can be quickly installed on the platen of the press. It is a further object of this invention `to provide a die press stop which can accommodate a wide range of stock thickness.

Other and further objects of this invention will become apparent in the detailed description below of one preferred embodiment of our invention when taken in conjunction with the attached drawings, wherein:

FIGURE 1 is a plan view of a platen illustrating the use of die press stops of our invention;

FIGURE 2 is an enlarged fragmentary, partial crosssectional view taken along line 2 2 in FIGURE 1;

FIGURE 3 is a fragmentary partial cross-sectional view taken along line 3-3 in FIGURE 2;

FIGURE 4 is a pictorial view of the die press stop shown in FIGURE 2 as seen from below and to one side; and,

FIGURE 5 is a pictorial view of the die press stop in FIGURE 2 with the cap thereof separated.

Referring now to FIGURE 1 there is shown a platen which customarily is a heavy plate of metal on which the stock to be processed is located. In this case, two pieces of rectangular stock 11, e.g., cardboard, is located on the platen and properly indexed by plurality of die press stops thereon.

To this end a pair of die press stops 12 and 13 are anchored to the platen 10 at left edge 14 of the platen. Similarly a pair of die press stops 16 and 17 are anchored 3,232,693 Patented Feb. l, 1966 to the face of the platen 10 immediately adjacent rear edge 18 of the platen. With this arrangement the operator stands in front of front edge 19 of the platen llt)` and urges the stock 11 against the respective stops 1'2, 13, 16 and 17 to properly index the stock.

At this point, the press is closed and the steel rule cutting and creasing die carried by the base performs its intended function, e.g., cutting out a portion of the stock along phantom line 22.

It should be noted that normally the stock is not intentionally disposed on the platen such as the stock 1.1 is disposed on the platen It?. The particular orientation of the stock 11 and the shape of the cut as indicated by the phantom line 22 are to illustrate the versatility of die press stops embodying the present invention. This versatility will be alluded to further in the specilication below after the illustrated preferred embodiment of our invention has been described.

Referring now to the FIGURES 2 to 5, the die press stop 16 will be described in detail. The die press stops 12, 13 and 17 are substantially the same. However, it should be noted that the cap of the die press stop 17 has been removed for a purpose which will be discussed below.

Preferably the die press stops of the present invention are made of a plastic such as polyethylene because it takes the abrasion of the stock very well. Other materials such as nylon also can be used. The die press stop 16 comprises an elongated base portion 24 having a flat bottom face 2S with a planar top face 26 a short distance thereabove. As will be pointed out below, it is intended that, in some applications stock be received on top of the face 26 of the base portion 24. Accordingly, edges 27, 28 and 29 of the base portion 24 are tapered upwardly to facilitate this.

At its end 30 the base portion 24 is provided with a generally rectangular upstanding portion 33 which terminates in an upper edge 34. The upstanding portion has a first abutment wall 35 which extends at a right angle to the bottom face 25 from the edge thereof. The abutment wall 35 receives in engagement therewith the stock 11 when the Idie press stop is oriented as in the case of die press stops 16 and 17, in FIGURE l.

On the opposite side of the upstanding portion 33 is an abutment wall 36 which i-s parallel to the wall 35. As will be explained below the wall 36 engages the edge of the stock when the die press stop is used as the die press stops 12 and 13 in FIGURE l.

Adjoining walls

37 and 38 join the respective edges of the walls 35 and 36.

The die press stop 16 also comprises a cap` 40 which will be discussed in detail below. This cap 40 cooperates with the upstanding portion 33 of the stop so as to be adjustable up and down. To this end a rectangular cavity 41 is provided in the upstanding portion 33 and has a pair of parallel opposed walls 42 therein extending parallel to the walls 35 and 36. As can best be seen in FIGURE 2 a pair of opposed walls 43 join the respective edges of the aforementioned walls 42. It should be noted that the walls 43 converge downwardly for a purpose which will be described.

Turning now to the cap 40 in more detail, it includes a flat, square head 47 which substantially as wide as the walls 35 and 36. However, the cap 40 is dimensioned so that it will overhang the walls 35 and 36 to provide lips or shoulders 48 and 49 respectively. Made with this arrangement the lip 48 will limit the movement of the stock 11 away from the platen 10. Similarly the lip 49 will limit such movement of any stock abutting the wall 36. In FIGURE 3 phantom line 50 is provided to illustrate such stock.

Depending from the head 47 of the cap 46 is a pair of somewhat flexible legs 51. These legs are dimensioned so that they may be received into the mouth of the cavity 41. Accordingly, as the cap 4t) is forced downwardly, the

aforementioned converging walls

4,3` bend the legs 51 inwardly. Because of this arrangement, the cap 40 may be selectively positioned at its lowest position such as shown in full lines in the FIGURES 2 or raised to the position shown in phantom lines in FIGURE 2. In each case the friction between the legs 51 and the converging walls 43 hold the `cap 40 in the desired position. This enables the present die press stop to accommodate Very thick stock or several layers of stock.

Another feature of our invention is the manner in which the die press stop may be quickly anchored to the platen 1G. To this end the bottom face 2S is coated with a contact adhesive or cement 53. Prior to use the contact cement S3 is covered by a protective .paper 54 which is either wax coated or has a very hard nish in order that it may be removed easily.

At the time it is desired to apply the die press stop to the platen, the paper 54, which comes in two sections, is peeled off by pulling said paper in the direction of arrows SS. (See FIGURE 4.)

The versatility of die press stops according to the pres ent invention is readily seen. For example, in addition to the manner in which die press stop 16 is used, the stop can be used as in the case of stop 12 or 13. ln this case the stop can be anchored to the platen at such a position that the stop actually extends beyond the edge of the platen. This enables the platen to accommodate larger sized stock.

Additionally the cap 40 can be positioned up or down in accordance with the demands of the particular job, or it can he completely removed as in the case of die press stop 17 and still accomplish its intended function. In the case of die lpress stop 17 it is necessary that the cutting die cut the stock 11 so closeto the stop that the die would hit the cap if it had not been removed.

Another feature of the present invention is the manner in which it lends itself to being economically produced of plastic. When forming plastics it is essential that all cross-sections be realtively thin in order to avoid warping of the final molded product. Accordingly the cavity 41 not only functions to cooperate with the legs S1 of the cap 40 but reduces the effective cross-section of the upstanding portion 33.

While only one embodiment of our invention has been shown and described in detail it will be apparent to those skilled in the art that such is by way of illustration only, and numerous changes can be made thereto without departing from the spirit of the present invention. Accord* ingly, the invention is to be limited solely by the scope of the appended claims.
