PLASTIC SOLE FOR SHOES Filed April 1'7, 1943 IN V EN TOR. dose/w BURGE A 7'TOR/VE X Patented Jan. 16, 1945 UNITED STATES PATENT OFFICE PLASTIC SOLE FOR SHOES Joseph Burger, Yonkers, N. Y.
Application April 17, 1943, Serial No. 483,386
Claims.
This invention relates to improvements in shoe soles for men and women and consists of a novel shoe sole made from plastic material, the principal purpose of which is to eliminate the conventional leather sole in shoes and substitute in lieu thereof a plastic sole.
The principal object of this invention is to provide a shoe with a plastic sole which plastic sole may be either pro-fabricated or may be applied in a molten state to the shoe.
Another object of this invention is to provide a plastic sole for shoes that is rugged and inexpensive to produce and will afford comfort to the wearer.
With the foregoing and other objects in view, the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
A practical embodiment of the invention is illustrated in the accompanying drawing, wherem Figure 1 is a perspective view of the Army type hoe partly broken away, so as to illustrate the interior construction of the plastic sole.
Figure 2 is a bottom view of the shoe sole partly broken away.
Figure 3 is a sectional view taken on line 33 of Figure 2.
Referring to the drawing, l0 denotes a conventional form of army shoe comprising an upper I I, heel I2 and inner sole I3. The inner sole I3 may be fixed by stitching I4 to the welt 9.
The welt 9 is provided with a cup like extension I6 thereof forming a chamber C the purpose of which will be hereinafter described.
In order to provide the inner sole l3 with an outer sole such as I5, plastic materal is utilized. The bottom surface I! of the inner sole I3 is roughened so as to increase the bondage between said inner sole I3 and the plastic material that is poured into the chamber C.
When it is desired to increase the bondage of the plastic material housed in the said chamber C, a reinforcing wire W is added by passing it from one side of the welt extension I6 to the other side of the welt extension I6, starting at a point I8 about mid-way of the height of said welt extension I6. Said wire W will pass outside of the welt for a relatively short distance and then pass through the welt again-at I9 and is run back and forth through the entire length of the sole to near the tip end thereof to 20, the wire W being spaced apart and parallel to each length. Then the wire W may be run back and forth, at right angles to the first direction of said wire W as at 2| and terminate into its end at 22, as especially shown in Figure 2 of the drawmg.
The two rear ends of the welt extension I6 are each secured in a cut out 23 by means of tacks 24 to opposite sides of the heel I2 of the shoe II].
It will thus be seen as a result of the reinforcing wire W utilized in the plastic sole, the retention of the plastic sole within the inner sole is greatly assured and furthermore the shape of the welt extension I6 is also reinforced to keep it rigid and in proper shape at all times.
In some instances it may be desired to apply the plastic material in a flowing state into the chamber 0 without any reinforcing wire W. This is accomplished by merely directing the plastic material into said chamber C so as to formulate a sole therein.
'A plastic sole may also be formulated separately and apart from the shoe I0 and then said preformulated plastic sole is to be applied in the chamber C of the shoe III as may be desired.
It is to be distinctly understood that any desirable suitable plastic material may be used in forming the plastic sole I5, such plastic material may be a cement composition, cold molded composition, casein composition material, and furthermore plastic material of the thermosetting or thermoplastic type may be employed, as well as coldsetting plastic material.
It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.
As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth is to be interpreted as illustrative and not in a limiting sense.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. In a shoe, comprising a heel, an inner sole, a welt extension, a chamber formed by said welt extension, a plastic sole, said plastic sole located in said chamber, means for reinforcing said plastic sole and said welt extension, as and for the purpose set forth.
2. In a shoe, comprising a heel, an inner sole,
a welt extension, a chamber formed by said welt extension, a plastic sole, said plastic sole located in said chamber, means for reinforcing said welt extension, as and for the purpose set forth.
3. In a shoe, comprising a heel, an inner sole, 9. welt extension, a chamber formed by said welt extension, a plastic sole, said plastic sole located in said chamber, metallic means for reinforcing said plastic sole and said welt extension, as and for the purpose set forth.
4. In a shoe, comprising a heel, an inner sole, a welt extension, a chamber formed by said welt extension, a plastic sole, said plastic sole located JOSEPH BURGER.
