LINING FOR RUBBER ARTICLES Original Filed May 19, 1927 ffufen't rs I [50%; Zfir aay azzdefl/yason so stantial lining for Reissued May 5, 1931 UNITED STATES PATENT OFFICE CHARLES E. BRADLEY AND CLAUDE D. MASON, OF MISHAWAKA, INDIANA, TO MISHAWAKA. RUBBER AND WOOLEN MANUFACTURING COMPANY,
ASSIGNOBB OF MISHA- WAKA, INDIANA, A CORPORATION OF INDIANA IIIN'ING FOR RUBBER ARTICLES Original No. 1,677,428, dated July 17, 1928, Serial No.
filed July 16, 1930.
Our invention relates to rubber linings for rubber articles and has reference more particularly to a construction whereby rubber articles of light weight and having a high degree of flexibility and elasticity may be produced.
In the manufacture of rubber articles it is important, especially in close fitting types, to provide a lining to facilitate putting on an taking off and to avoid direct contact of the rubber with other articles of clothing or with the body of the wearer, and aiford a non-conducting layer ermitting a movement of air between the ru her article and the clothing or the body of the wearer for avoiding unpleasant heating which would otherwise occur.
An illustrative example of such conditions is in the rubber footwear art where a fabric lining is satisfactory for ordinary and heavy duty types of rubber footwear, but it is desirable to provide finer grades of rubber footwear oflight weight and having a high degree of flexibility an elasticity, and this has not been successfully accomplished heretofore, as a suitable lining was not available. A fabric lining would not do as it sacrificed flexibility and restricted the elasticit of the rubber to such an extent that it de eated the desired urpose and moreover, it would pull loose rom the rubber when the latter was stretched re eatedly, as required in actual use.
ith our invention, however, we have overcome the difliculties heretofore encountered by using a thin coating of comminuated fibers, which are applied to the inner surface of the rubber and thus provide a lining which does not affect the elasticity or flexibility of the rubber and which will not pull loose when the rubber is repeatedly stretched.
The rincipal objects of our invention are to pro uce satisfactory light weight highly elastic rubber footwear; to provide an im= proved lining for rubber footwear, to preserve the elasticity and flexibility of the rubber; to provide alining which will readily shape itself to the form in which the rubber is assembled in the article of footwear; to minimize the expense of lining rubber footwear; and in general, to provide a simple and subrubber footwear which rubber.

may be easily applied and which enhances the appearance of the article of footwear.
On the drawings:
Fig. I is a perspective view of a common form of rubber, showing our im roved lining, a pcprtion of the sidewall beingbroken away; an
,7 Fig. 2' is an enlarged sectional view on the d line 22 of Fig. 1.
Referring to the drawings, the reference numeral ,1 indicates a rubber of a well known type, the side wall or upper 2 of which is provided with a lining 3 in accordance with our invention. The upper is preferably made of a special quality stock with sufficient toughness to withstand the required strain and isquite elastic, a-nd the upper edge of the side wall is preferably reinforced against splitting or tearing in a manner which will not restrict the elasticity or stretchingas for example by an elastic tape 4, which'is embedded in the upper edge of the side wall of the rubber and extends around the mouth of the latter.
The rubber may be provided with the usual insole 5 of fabric, but the remaining inner surface of the rubber or inner surface of the upper is covered with a coating 3 of comminuted fibers, which are adhesively applied to the inner surface of the side wall of the rubber, so A as to afford a complete coating which conceals and covers'the inner surface of the upper.
We have found that finely divided ground cotton, wool or silk specifically known as floc may be used for the lining to good advantage and at the same time does'not detract from the highly elastic properties of the Besides avoiding direct contact of the rubber with the shoe and providing the necessary smooth feel and consequent improvement in ease of putting on and taking off the rubberzor other similar article, this flock coating also gives a nonconducting layer between the article and the leather shoe, permitting a movement of the air between the rubber and leather shoe and avoiding heating of the foot, which would otherwise occur. 11 addition this inner coating of flock gives an attractive appearance, as it may be colored any desired color.
I which 7 rubber foot The flock may be applied to the rubber in any suitable way, but we have found it advantageous to apply the flock on the stock as it comes from the calender and while the rubber is still warm and tacky. (After the footwear is made up with the flock lining sticking to the inner surface of the rubber, the footwear is vulcanized in the usual manner,-and this securely combines the particles of material composing the flock with the surface of the rubber, 'so that a permanent lining results which will withstand the usage and wear to ear are subected.
While we have shown and described our invention with particular reference to rubber footwear, we are aware that various changes and modifications may be made to apply it to other rubber articles for covering or protion of an elastic up tion and a lining 0 sively applied to tecting other portions of the body and Without departing from the principles underlying the invention, consequently reference should be made tothe appended claims for an understanding of the scope of the invention.
Having thus described our invention; what we claim and desire to protect by Letters Patent is:
1. In'an article of footwear, the combination of an upper composed entirely of elastic rubber composition with a lining of comminuted fibers applied to the inner surface thereof so that the extensibility of the lining is limited solely by the elasticity of the rubber composition. p
-2. In an article of footwear, the combination of an u per of highly elastic rubber composition an a freely extensible lining adhethe inner surface of the up per so that enlargement of-the upper is limited solely by the elasticity of the rubber composition.
3. In an article of footwear, the combinaer of rubber composiseparate comminuted bers uniformly distributed over and adhesively securedto the inner surface of the upper, said lining being freely extensible so that the stretching of the upper is unrestricted thereby. V
4. In an article of footwear, the conibinaan upper of rubber composition and therein consisting of minute separate' particles of fiber unconnected except by adhesion to the rubber. p
5. An article of footwear comprising a sole and an upper the latter'being composed of thin high y elastic rubber composition and a lining consisting of minute particles of fibrous material connected solely by adhesion to the rubber composition of the upper, said particles being free to move relatively with the stretching of the rubber.
(ii In an article of wearing apparel shaped to t a portion of the human body, the" combination of a wall of rubber composition vulapparel, the
sistlng of minute separate particles of fiber unconnected except e 8. In an article of Wearing apparel, the combination of an elastic body of rubber composition vulcanized in a form to fit a portion of the human body and having a lining of separate comminuted fibers tributed overand adhesively secured to the inner surface of the body, said lining being freely extensible sbdthat the stretching of the body is unrestricte thereby.
9 In an articleof wearing apparel, the combination of a body composed entirel of elastic rubber composition, vulcanized in .a form to fit a portion of the human body and having a lining of comminuted fibers applied to the inner surface tlfereof so that the extensibility of the linin is limited solely by the elasticity of the rub r. composition.
