Fig. 3 is a section of a portion of the machine taken along the line 3-3 of Fig. 2.

I In the illustrative -machine there is disclosed one embodiment of the invention which may be used in practicing the novel method of cutting sheet material into blanks described in detail and claimed in this apdisclosed the machine comprises a work support 6 upon which sheet material rests during cutting operations effected bymeans of severing knives 8 arranged in regularly spaced relation upon a crosshead 10. Preferably sheets or'strips of stock will be fed by suitable means (not shown) from a magazine (not shown) into position on a work support or table 6, a gage 12 being provided at one end of the table for determining the correct location of the strips for the cutting operation. According disclosed the strips are out into sections of uniform size while they are supported by a strip which has already been cut into sections, this arrangement being for the purpose of providing a fresh cutting bed for each strip or set of strips that is out, and of preventing mutilation of the knives 8 or of the work support 6 during cutting operations It is necessary, in starting the operation of the machine for the first time, to position sections'ofthe proper size on the cutting bed 6. There after the machine operates on fresh strips placed on top of the previously sectioned strip or strips and removes the bottom sectioned strip after each succeeding cutting operation. By this removal a freshly cut or sectioned strip is deposited upon the table 6 and serves as a cutting bed for the succeeding sheet or strip of material so that the cut ting edges of the knives 8'pass throughthe strip being cut and into the spaces between The bottom sections are comprising in the illustrative machine, forked feeding members 14 which have fingers'16 so arranged as .to feed adjacent sections in opposite directions as the feedin members approach each other. Preferablythe feeding members are simultaneously operated by means comprising shafts 17. In order to effect the feeding operation, the fingers of the two feeding members 1% are staggered relatively to each other and pass into interlocking arrangement across the work supporting table 6. As the sections 18 leave the table 6 they pass over the upper open ends of dies 20. These dies are of sufiicient size to form heel lifts having maximum width approximately equal to the width of a section of material, and are made -hollow in order to receive lifts as they are died out. The dies 20 are arranged in two rows one on each side-of the table 6 and spaced from. each other in the row a distance corresponding approximately to one dimension of the sections. This dimension is also practically equivalent to a transverse dimension of the dies so that, if the two rows of dies were moved directly toward each other until the dies were all arranged in one row, each die would be in contact with each adjacent die. In other words, by this arrangement of dies blanks are cut so from the sections of sheet material as to leave practically no scrap material at the sides of the sections. Since it is not possible in a practical machine to arrange the dies so closely together in one row, the arrangement adopted has the advantage of efiecting the same saving of material by cutting blanks with as little waste as would occur if they were cut in a hypothetical machine havingdies arranged in contact with each other.

In pushing the sections of the lowermost strip from the supporting table 6, it is obvious that sections above and resting on the lowermost sections would be displaced'laterally were no means provided for preventing such displacement. As shown, holding or retaining members 22 are provided detachably mounted on side bars 2% and hav ing flanged ends 26 disposed insuch a way as to prevent movement laterally of all but the lowermost sections which rest on the table 6. While the flanged ends 26 of the retaining members are shown to present plane faces toward the medial line of the table, it is clear that said faces may be curved, especially at the ends thereof, in order more readily to guide the uncut strips of material as they are fed from the magazine on to the work supporting table. After the sections 18 have been positioned over the dies 20, relative movement between the Sitld. dies and co-operating blocks or presser "members 28 is effective to cut or d1e out heel lifts from the sections. In the illustrative machine crosshead members are provided at opposite ends of the work support 6 for carrying the crosshead 10 and presser members28. One of the crosshead members is shown at 30, and is adapted to be reciprocated upon guides 31 by means of any suitable mechanism. Upon downward movement of the crosshead members, a strip or essence setof strips of material is-sev'ered into sec tions and simultaneously a set of sections are died out into blanks by beingfitorced through the stationary dies Beforethe 'first operation of the machine" sections are" placed upon the upper edges of the diesQ'O and at the first reciprocation of the'bloc-ks 28 the said sections are forced only partway into'th'e" dies; Subsequentoperations of the blocks 28 force the partly cut sections through the dies and leave other sections partly cut through on" the upper' edgesof the dies as indicated in Fig; By: this arrangement the cutting edges of the dies" never come into" contact with the facesof the block's'28 so that thereisno injury or mutilation of these co-operating' surfaces in the" machine. Moreove'r, by thisarrangement the sections as they" are' cut are" pro 2 vided successively with constantly new cut-'- ting"'bed surfaces" in the succeeding sections so that the" edges of the cut blanks are always cleanly cut. The re'moval'of the cra material which, in the present instance, is'reduced' to" a minimum is insured by means includi'ngblades 32', each die having two" blades "located oppositely to each other 'andh-aving their sharpedges in the same plane" as the cutting edge ofthe die. Thus, as a section is cut to make a blank, the surrounding" portion of scrap material is severed at two points sotha't it readily falls away from the die While the blank passes througirthe" die into a magazine or'other receptacle provided" forthe urpose; As'the scrap material leaves the" die'itfalls upon a plate 34;having. portions inclined in 0pposite directions from which thescrap slides to theffloor or to a. receptacle" provided" to receive such material, 7 the said inclined plate; in the structure disclosed, forming part or all of the'sup'port for thedie'sQO;

In practicing the method of cutting sheet material herein disclosed by means of a machine such as that illustrated in the draw ings, strips of material arefedinto the machine from the right against a gage such as that shown at 12 and the machine is operated to cut the strips into-sections While the previously cut or sectional stripserves as a cutting bed-during the cutting operations; It is clear that this method has the marked advantage of simplicity in the steps in volved since the fresh sheets of material to be operated upon are fed always on top of those previously positioned in the machine and the. cut o1 sectioned stripsa-reremoved from the bottom of the pile, no other positioning or rearranging of the strips being necessary. A further marked -advantage-of the in vention', in its practical application, resides in the feeding of the sections of strips in opposite directions, since by this arrangement the'sectionsinay' be cut veryclose" to th'esize= of the desired blank, These sectionsmay'then" he cut into blanks hy-it he use of dies arranged in such EL 'WaY'With rela t on to eachother that the arrangement equivalent-"0fdies in a single ro'W'in' 'cl e' con-tact ivith each' other" throughout; thusmaking it possible to cut sheet materialin te blanks with the accompanying"produetien of little or no'serap or Waste material.

It sheuld be pointed 'ou-tthatifin t inven tion contemplates the cutting oi aplurality! offsheets-"or strips at one time-into sections While other"previously cut' or sectiened strips serveasa cutting bed,and their feed ing a plurality ofsecti on's over eachdiets have blanks cuttherefrom; Thus, the in vention isrnot limited in-any way the disclosure of the specific machine which; indeed, is illustrative only (if-one embodi ment of mechanism for practicing the novel methodof the invention, the breadt h of the invention being determinable by the scope of the appended claims. j v
