DOMINIOK A. MCDONALD, OF ROOKLAND MAINE, ASSIGNOR TO MolDONALD BOOT AND SHOE.
. SPECIFICATION forming' part of Letters Patent No. 231,830, dated August 31,1880.
Application nieu June 12,1880. (Nomodei.)
To alb/whom 'it may concern:
Be it known that I, DoMrNrcK A. McDoN- ALD, of Rockland, in the county of Knoxand State of Maine,have invented a new and useful 5 Improvement in Boots and Shoes; and I do hereby declare that thefollowing is afull, clear, and exact description of the same.
My invention relates to the ventilation of boots and shoes, and is an improvement upon 1o the device shown in Letters Patent granted me on the 13th day of April, 1880, numbered 226,532.
The invention consists of an air-chamber for more perfect ventilation, located centrally with- 15 in the sole of the boot or shoe, about the ball of the foot, and provided with openings to the interior of the shoe, and with communication with the tubular passages of coiled wire, which extend upward and open to the outside. This zo air-chamber may be made in various ways.
In the drawings hereunto attached, Figure l represents a form of the chamber with communications in the bottom of an ordinary insole. Fig. 2 is a top view of the same insole.
z5 FignB is a section on line a; x, and Fig. 4 a
section on line y y of Fig. 2.
In these figures, a a represent the coil of wire, such as is shown in my patent heretofore referred to. This coil is represented as eX- 3o tending around within the sole of the boot or shoe and backward to the heel, whence each end extends upward along the side ot' the leg. Between the loop is located the air-chamber b. In the form shown it is made Within theinsole 3 5 by cutting grooves in the under side both transversely and longitudinally of the sole, the transverse grooves opening into the groove in which the coil of Wire is placed, and such transverse grooves are also provided with y 4o the tubular coils which keepthem open and prevent the edges from being flattened by pressure. These grooves form air-spaces, and as they are connected by numerous perforations c c c with the interior of the boot or shoe, they form greatly-increased lneans of communication between the interior of the boot or shoe and the external air. Without such a chamber and the perforations connected therewith the only means of communication between the interior ofthe shoe or 5o boot andthe exterior would be through the holes d d, along the line of the coiled wire. This leaves the central part without ventilation-a partordinarily most necessary to ventilate and most readily acted upon by the foot 55 in walking.
The air-chamber described may be formed in other ways. rlhe inner sole may be cut out and a piece of rubber, stamped or cut in the sameshape as thcleather sole above described, 6o may be inserted in the place 5 or transverse grooves with lines of perforations may be used without the longitudinal grooves.
Manifestly the invention is equally applicable to rubber as to leather goods.
Having thus described my invention, what I claim is The described improvement, consisting ot' the chamber located in the sole and included within the loop of coiled wire, also in said sole, 7o the said chamber being connected with the coil, and also having openings to the interior ofthe boot or shoe, the Whole being arranged. substantially as shown and described.
In testimony whereof I have signed my name 75 to this specification in the presence of two subscribing witnesses.
DOMINIOK A. MGDONALD.
