The curve of the notches 5 is greater than the bearing face of the arms 8 at the notches 9, so that the arms bear upon the blade at a single point and the notches 9 are i-wider than the blade as shown in Fig. 9.

a Thisprovides a limited-freedom of movement betweenthe holder and the blade, so that downward pressure exerted through the holder up'on the blade results in a true seating of the cuttingedge of the blade upon the blank, regardless--of the exact relative position of the holder with respect 7 Y to the blanksurface.

'bodiment of myinvention. a holder 6b is,in"eifect, straight 'exc'eptfor'the having a short straight cutting edge usedfor connecting other cuts made bythe other dies. 1 In this instance thenotches 5d'are angular and'the arms of the holder rest against the two' walls of" the notches, holding the blade firmly m the holder. I

In Fig. 13, I have shown a modification of the invention; The blade "11) in this instance "has .a

1 hole'5b of any shape, and the holder 6a has two parallel clamping members 8a, each having an external notch 91;. a When not engaging'the blade,

the spring clamping members are spread apart, and are forced towards each other to enter the hole 'in the blade, and "when. released they will engage the edges of thehole asshown. f In Fig. 14, I have illustrated a preferred emtransversely offset extremities which provide the "holder withthe necessary capacityito'embrace the width of the cutting blade. .The extremities of th'eholder in this'instance and as shown in Figs. 15 and .16 are provided with'slotsQb forre- "ception' of the oppositeedges of the cuttingblades. These slots, see Fig. 16, are'of greaterfwi'dththan the'thickness ofthe blade, and are'also formed.

the holder at an angle affording, between" the plane of the holderand the plane'of the clamped -dies aniangle somewhat in excess of 90, this an- I gular relation between the holder and the blade fbeingclearly shown in both Figs; 14' a1id 16QjIt is: this angularity 'of thISlOtQb which permits "the holder 6b to be made straightas; distinct from I the holders 6 and Gashoivriin the preceding figures; This has a considerable manufacturing advantage, in that it reduces the costof produc- .tion.

' It will further be noticedf'by reference .to'Fig.

1 5that the slot 9b isjformedso' that'only the lower edge thereof engages in'the n0tch 5b of the cut;

' 'ti'ng 'blade', which gives, in effect, a pointicontact "between theholder and the cutting blade.

in conjunctioniwith the extra width of the slot 1 9b in excess' of the thickness'of the blade, affords the desired flexibility or freedom of adjustment 7 between the blade and the'holder previously described. The fact that. the holder tends to en gage, the 'extremebottom'of'th'e notch 5b in the "blade insures in this case that the sharp edge of theholder at the bottom of the notch will engage the blade at the bottornof the notch 5b, as shown 7 in Fig; 15,-whichinsures thegreatest possible firmness of grip between the holder and the blade. to the blade through the holder without danger Relatively heavy pressures'may be applied of displacing the holder from the notches.

In Figs. 11 and 12, I have shown abladeld the blade to seat accurately upon the blank t o'be In this instance,jthe

This,

In Fig. 1'7 a rectangular box l3is shown which contains the holder 6, a seriesiof cutting blades 1, a hammer 14, and a cutting block 115. The several elements are so arranged as toflt in 'a a comparatively small box asshown. I 5

The box also contains one or more blanks divided into sections, such as l 6-16 1, of a size-permitting insertion thereof withinthe. box. These sec tions as illustrated are divided along lines-corresponding sectionally in contour to the dies or cutting blades contained in the box,and provide a visible indication to the purchaser of the manner in which the dies are employed. In order further to aid the-purchaser in thisrespect, I may form I-claim; f-' I I 1. The combination ofacutting blade ha in "notch at each edge; and a holder having two notched clamping edges arranged to engage the blade at the notches, the holder being less in diameter'than' the notches in' the blade to allow cut irrespective of any slight pivotal movement 2. The combination of a cutting bladejofshaped sheet metal havingin'otches in"fopposite edges .1 thereof; and a holder havingbifurcations adapted toengage, in said notches sai'd bifurcations liav- 1 ing recesses for reception of the edgesiof said blade, and said recesses being -'of greater-width thanthe'thickness of saidblade; and mea s proto viding for, substantially point contact between said bifurcations", and the blade," respectively,

whereby said 1 blade is afforded a limitedfreedom for rocking movem' n't between" the-bifurcations 3. The combination with a cutting blade-"of shaped sheet metal having notches in opposite edges; 'of a holder havingbifurcations adapted to engage in said notchesandsaid-bifurcations having recesses for reception ofuthe- -edges of"the-5O blade, the bifurcations of said holder being formed to occupya common plane, and said' 'recesses being formed at a slight angle to said-'-plane whereby the blade is heldin the holder atacorresponding angle to the plane of the latter. a

4. Thecombination of a'cutt'ing blade of shaped sheet metalhaving a cutting edge and'a blunt I striking edge and a holderhaving notched arms arranged to engage the blade at two points',said

. arms engaging the blade at' points, between the utting edge and the strikinged'ge'g'theiarms being the sole support'ofitheblade,the connection between thefhold'er and theiblade providing a limited relative movement .between '-the,..blade* and the holder, .to-insure the true-seatingof the cutting edge of the blade upon the blank, regardless of the exact relativeposition of the holder-with respect to the blank surface. v
