piairnn snares rarnnr orricn CARL LorrLEa, or ERFUR-T, GERMANY.
To all whom it may concern Be it known that I, Dr. Med. CARL Lorr- LEE, a subject of the German Emperor, residing at Erfurt, German Empire, have invented certain new and useful Improvements in Ventilated Footwear, of which the following is a specification.
The present invention has refernce to ventilated footwear, and it proposes, briefly, a boot, shoe or like article which is formed with an improved system of passages, channels and openings or perforations so arranged and connected together as to insure a circulation of air around the entire foot of the wearer.
In the accompanying drawing: Figure 1 is a transverse sectional view of an article of footwear provided with the improved ventilating system; Fig. 2 is a top plan view of the inner sole; and Fig. 3 is a longitudinal section taken on line AB, Fig. 2.
As shown in said drawing, the inner sole a is pierced by a series of openings 6 which are arranged .in rows disposed substantially parallel and transversely of the sole. These openings 6 extend through the sole, and the openings of each row are connected by upper and lower main channels cl and (Z that are formed in the corresponding surfaces of said sole, the channels terminating with the outermost openings of the rows.
The openings just specified are remote from the edge of the sole, but communicate directly with the inner ends of a series of auxiliary channels 0, which extend to said edge, as plainly shown in Fig. 2. At their outer ends, the channels 0, which are formed in the upper surface of sole a, directly communicate, in turn, with the ends of a series of channels 6 that lie between the upper h and the lining g and may be formed either in the inner surface of the upper or in the adjacent surface of the lining, assum ing that the lining is composed of material suitable for such purpose: the former construction, however, may be considered as preferable and as shown in the present instance.
The channels 6 communicate in some suitable manner directly with the atmos phere', and in the construction illustrated Specification of Letters Patent.
Application filed. March 13, 1913.
Patented Feb. 10,1914. Serial no. 754,138.
this connection is efiected by means of outlet openings f which pierce the upper and lead from said channels.
Beneath the inner sole (0, there is preferably disposed an intermediate sole is, as shown in Figs. 1 and 3, this sole is being made of loofah, cork or other highly porous material which may be impregnated with a suitable preservative such as boracic or salicylic acid, and with any well-known odor-destroying solution or composition, as, for instance, chlorid of Zinc or manganese.
By reason of the arrangement of the series of channels and their various openings, as above described, it will be apparent that complete and constant ventilation is provided for, and the foot is kept dry, since the air passes entirely around the foot and finally escapes through the outlets to the atmosphere, and this action is furthered to a considerable extent, owing to the employment of the saturated, porous intermediate sole.
I claim as my invention.
1. A ventilated article of footwear having a series of transverse channels provided in its inner sole, the channels extending at opposite ends to the edge of said sole; and also having a separate series of channels provided between its upper and lining, the second-named channels communicating at their opposite ends directly with the adjacent ends of the first-named channels and intermediate their ends with the atmosphere.
2. A ventilated article of footwear having its inner sole provided with a series of transverse rows of openings formed therethrough, with upper and lower main channels formed in the corresponding surfaces of said sole and connecting the openings of each of said rows, said channels terminating with the outermost openings of the rows and with auxiliary channels extending from the ends of the main channels to the edge of said sole; and also having a separate series of channels provided between its upper and lining, the last-named channels communicating at their ends directly with the outer ends of the auxiliary channels and intermediate their ends with the atmosphere.
3. An article of footwear having a ventilating system embodying two series of in said inner sole communicating with said channels communicating with each other and intermediate sole. 10 with the atmosphere and located in its inner In testimony whereof I afiix my signature sole and between its upper and lining; and in presence of two witnesses.
also having a porous intermediate sole which DR. MED. CARL LOFFLER. is located between its inner and outer soles Witnesses: and is impregnated With a preservative and G. Solmonnn, odor destroying composition, the channels ALFRED HOFFMANN.
