MEANS FOR MAKING SHOES Original Filed Dec. 20, 1955- 4 Sheets-Sheet 3 Patented Jan. 15, 1 935 1 Fred Maccarone, Brooklyn, N. Y. Original application December 20, 1933, Serial Divided and this application June 12, 1934, Serial No. 730,179. In Canada April 6 Claims.

My present invention relates to matter disclosed in 'my co-p'ending applications Serial Nos. 671,109 and 703,237 filed May 15, 1933 and December 20, 1933, respectively, and is a division '5 of the latter application.

A principal object of my invention is to pro vide improved means for -making shoes of the type originally taught in my United States Patent No. 1,569,823, wherein an insole. to which the upper is aflixed, includes an integral heel portion, a shank portion, and a ball portion having a central opening therein defining a continuous marginal rand extending from the front of one side of the shank around-the toe and .to the front of .the opposite side of the shank to afford means for initially afiixing the upper to the insole, and an outsole is provided having a marginal depression conforming to the rand for receiving the same with'the upper attached thereto, whereby the central portion 'of the inner face of the outsole is disposedfiush with the upper surface of the rand.

A further principal object is to provide means for producing an outsole and a complementary insole therefor, whereby the insole and outsole portions of the shoe are patterned and sized at the same time from a single piece of sole material to insure that the insole and outsole portions are of relatively proper shapes and sizes.

A further object is to provide a combination pattern and cutting die for rounding the outsole and initially forming an insole for use therewith. Other and further objects will appear from the following specification.

Referring to the drawings: I

Figure 18 is a perspective illustration of a plate, similar to the upper plate shown in Fig ure 16, contoured to define an insole, and carrying a marginal blade for incising and initially forming an insole as the material is clamped in the rounding machine.

Figure 19 is a sectional view taken on line 19--19 of Figure 18. g

In carrying out my present invention I prefer to first incise the sole material to define an insole portion of suitable size, thickness and proportions, and then to round the outsole from the same piece of material in relation to the insole thus defined.

To accomplish thisI may employ a pattern or template, as shown in- Figure 1, which com prises a body portion 20 and side and end portions 21 and'21, between which I removably secure thin and flexible cutting blades 22-22 by means of countersunk screws 2323 .etc. The

' is reenforced by a perforate backing strip 36.

(See Figure 11) which is formed to'complement the depressed portion of the sole and is preferblades22 are positiori edland arranged to extend outwardly from the face of the pattern a distance corresponding to the thickness of the insole to be provided "and are contoured in conformity with the sole portion of the last on which the shoe is to be assembled.

As indicated in'the drawings, it is usually not necessary that the full outline of" the insole be incised in the sole material or that the blades 22 extend to accomplish that purpose inasmuch as the insole ordinarily conforms in size and shape to the outsole over the shank and forward portions of the heel and may be formed with the outsole in the sole rounding operation here after to be described. 1

In all other respects the pattern is of the usual type heretofore employed and is provided with holes therethru at 24 and 24 to receive the positioning pins 25-25 of a conventional sole rounding machine, fragmental supporting parts of which are indicated at 26 in Figures 2 and 3. l When the pattern has been positioned on the sole rounding machine, a piece of sole material 27, of uniform thickness, is laid over the pattern and rests upon the cutting edges of the blades 22, whereupon the clamp 28 of the rounding machine is forced down upon 'the material, causing the blades 22 to cut into the material and firmly holding the material against the face of the pattern during the rounding operation performed by the knife 29, as indicated in Figures 1 and 2. The rounded sole 30 is then taken from the machine and appears with incisions therein as indicated at 3232 in Figures 4 and 5.v

'As illustrated in Figure 3, the blades 22 may be made to extend from both faces of the pattern so that alternate faces thereof may be employed to form the'sole portions of a mated pair of shoes.

Although I have found the foregoing method of producing the, rounded and incised sole 30 economical and otherwise of advantage, itwill be understood that the sole as it appears in Figures 4 and may be provided in other ways than that above described for the purposes of carrying out the further operationsof my improved method, and that the sole may first be rounded and subsequently incised to define the insole portion if desired.

a shoe, and that waste marginal portions corresponding to the material lying outside of the incisions and within the depth thereof will also result.

[Before performing such splitting operation however, I prefer to inflex or depress the central ball tread portion of the rounded and incised sole 30 to a distance somewhat greater than the depth of the incisions 32. This I accomplish by pressing the sole between the male and female elements, 33 and 34 respectively, of a swage or pressing die, as illustrated in Figure 7.

After removal from the pressing die, the sole ably made of a durable and somewhat flexible composition material. The sole thus backed up is then passed between the rolle rs 37 -37 of a conventional leather splitting machine, the splitting blade -38 of which positioned to cut within the depth of the, incisions 32 and above the bottom of the depressed area 35, so that when the sole has been split its-full length, an insole portion 39, perforate centrally of its ball tread portion, and an outsole portion 40, is provided. Waste marginal portions 41 also result from this operation, as will be readily understood.

The insole 39, formed as above, comprises an integral heel portion, a shank portion and a ball portion, the said ball portion having a central opening therein defining a continuous marginal rand. 39' extending from the front of one side of the shank around the toe and to the front of the opposite side of the shank.

The insole 39 is next lasted to the upper 42 of the shoe to which it is secured byany of such special adhesives as are well-known in this art, or by other suitable means, preliminary to which a patch 43 may be removably pasted to cover the perforate portion of the insole.

Theoutsole 40 is then. placed in position over the lasted insole and the depressed portion 35 thereof is forced back into itsoriginal normal disposed flush with the upper surface of the' rand. l a

The remainingsteps necessary to complete the shoe are the usual ones consisting in removing the patch 43, assembling the sole lining 50 and affixing a heel 51. Since the disclosure of the foregoing in my copending application No. 671,109 filed May 15, 1933, I have made valuable improvements in my original method which are disclosed in my -copending application Serial No. 703,237 filed .December 20, 1933, and the improvements in means which are particularly illustrated in Figures.16 to 19 hereof.

I have found that a plate 60 may be removably substituted for the clamp 28 of-the sole rounding'machine; that a pattern or template 61 may be substituted for'the; pattern 20; and'that the parts 60and 61 may be formed so as to depress the central area 35 of the ball portion of the than the thickness of the insole to be split therefrom. By providing the elevated areas and depressed areas on opposite faces of the parts Bil-61, respectively, I am enabled to use the same parts'for patterning. and depressing soles for mated pairs of shoes by merely inverting the plate 60 and pattern 61 in the sole rounding machine.

It will be understood that the sole material 27 is clamped under pressure in the sole rounding machine between the plate 60 and pattern 61,

thereby inflexing the sole material over the central area of the ball portion of the sole to be rounded, .and that the sole is then rounded in the machine by the blade 29 guided by the side edges of the pattern.

7 The sole thus formed and rounded may then be reinforced by the perforate backing strip 36 and split in the leather splitting machine above the bottom of its depressed area 35 to provide a rounded outsole and a perforate insole of lesser thickness and equal area.

I have further found that, in the operation of clamping the sole material in the rounding machine, I may also define and initially form an insole of suitable size, smaller than the outsole, by making a plate (Figure 18) of a shape and size correspondingto the insole desired and providing it with a double edged blade 22'. The blade 22' is secured by screws'23' to the plate at the margins thereof and extends perpendicularly from the unelevated face portions of the plate a distance corresponding to the thickness of the insole to be 'formed. In this manner the plate 60' is used to incise the sole material in much the same manner as the pattern 20 is employed, as heretofore described.

When the plate 60, carrying the blade 22', and the pattern61 are used together, the sole material is infiexed over the area 35 thereof and the incisions 32 are cut therein to define an insole. all in the act of clamping the sole material in the rounding machine. Subsequently, when.v the sole-has been rounded and split above the depressed area 35 and within the depth of the incisions 32, as previously set forth, the outsole portion 40 and complementary perforate insole portion 39 result. Thereafter, the upper may be amxed to the insoleand the outsole assembled thereto as above described to provide a finished shoe..

In this manner, I have provided a very simple and inexpensive method and means for producing my improved complementary outsole and insole members without adding to the number of operations ordinarily necessary for-their production, and with the further advantages of minimized waste and insured perfection of sizing. a

Many modifications in the method and means J here taught will become apparent from this disclosure to those skilled in the art to which this invention relates'and I desire, therefore. to have-the foregoing considered merely illustrative of my invention as defined in the here appended claims which are restricted tomy speciflc means, the method and improvements therein being claimed in. my copending applications above referred to.
