i C.OIVBINED DIE AND PATTERN I I l Filed Oct. 16, 1934 fnl/enof: Fred L. Fast e4' l 22)/ (722W /9 t#tto/Hey Patented Nov. 2, 1937 UNITED STATES PATENT OFFICE 1 Claim.
The invention relates to improvements in a combined die and pattern for cutting irregular congurations of articles, such as shoe parts, shirts, gloves, etc., of which the following is a 5 specication:
The invention consists of a novel means of supporting a pattern in a die by rigidly securing a reenforcing member having suitable supporting lugs formed integral therewith to the inner surface of the die which alternately support both sides of the pattern to make a substantial and durable structure.
The object of the invention is to provide a supporting means on the inner surface of a die for a pattern of any configuration to make a unit structure which is easy to manufacture at a maX- imum durability and a minimum cost.
Referring to the gures:
Fig. 1 is a plan view of the die and pattern showing the support.
Fig. 2 is a side elevation of the die shown in a cutting position in a checking machine.
Fig. 3 is a part vertical section of the die and pattern showing the supporting member.
Fig. 4 is a plan view of the same.
Fig. 5 is a side elevation of the supporting member.
Fig. 6 is a plan view of the same.
Fig. 7 is a side elevation of the supporting member before the supporting lugs are bent into position.
Fig. 8 is a fragmentary plan View of the die and pattern with the lugs bent into position.
Referring to the drawing which illustrate the improvements in supports for a combined pattern and double-edged die used for cutting material such as leather, cloth or ber in a checking machine towithstand the maximum cutting strains with a lightweight die. The die and pattern are indicated by the numerals I and II respectively. The die is made of thin strip material and preferably with two cutting edges I2 and I3 to permit left and ri-ght hand articles to be formed with the same die. The die operates against the stock I4 which can be of any suitable material.
The stock is placed on the cutting block I and the die is placed on the stock, as shown in Fig. 2 ,of the drawing, preparatory to the cutting operation. To force the die II through the stock I4 a reciprocating movement of the operating.
head I6 in its downward movement operates against the die forcing it through the stock, and the opposite upward movement away from the die allows the next operation to take place.
The die is made of a thin material which can be formed and manipulated around the pattern by machine or hand practice in contradistinction to the heavy forged dies now in use.
Because the die is made of thin material, the operating head I6 and the cutting block I5 are made of soft material so the die can sink into it and cushion the impact so the edges I2 and I3 will not be injured. The die is removed from the block by a special spring device to prevent them from sticking in the soft material.
The embodiment of the invention consists of a double-edge die made of strip material which can be readily formed to the contour of the pattern II of any conguration: that is, any form can be made and the die can be placed around it due to the exible nature of the material. The novelty resides in providing a suitable support for the pattern inside the die to withstand the working strains and reenforce the die when in use.
The reenforcing member I'I is also made of strip material which can be formed around the pattern and secured to the inner surface of the die Ill. Formed in the strip material are the supporting members I8 and I9. These supporting members are bent over at right angles to the inner surface of the die and reenforcing member, of which they are a part, at right angles and alternately extend over and under the pattern and all the members are welded together to make a unit construction for supporting a pattern to a die.
The reenforcing strip before it is secured to a die, is machined to form a series of two V-shaped slots on both edges of the reenforcing strip in alternate positions leaving the supporting members I8 and I9free to be bent at right angles to serve as the supporting member for the pattern, one set on the top side of the pattern, and one set on the lower side of the pattern.
In operation and construction the die III is made of flexible strip material having two edges I2 and I3 and is known as a double-edge die which can be used for right and left articles.
The pattern is made in any configuration and after the supports I8 and I9 are formed in the reenforcing member I1 it is bent around the pattern and welded. Following this operation, the die is now ready for operation.
What I claim as new and desire to secure by Letters Patent of the United States is:
In a double edge die in combination with a pattern of the shoe type, a supporting member secured to the inside surface of the die, lugs formed in the supporting member which alternately support both sides of the pattern.
