SPECIFICATION forming part of Letters Patent No. 619,665, dated February 14, 1899. Application led May 7, 1898. Serial No. 680,049 (No model.)
To all whom t may concern:
Beit known that I, TAYLOR E. BURT, a citizen of the United States,residing at Los Gatos, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Knee-Pads and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to knee-pads.
The purpose of the invention is to provide a shoe or device to be worn on the kneeand which is adapted to conform to the anatomy of the person and which will yield under differences of pressure.
The invention consists in the combination of a base or sole piece consisting of a troughshaped device either molded or pressed into the form. shown in the drawings, a pair of springs operatively connected with the sides or walls of the base, a strap or sling arranged athwart the sole-piece and held in position by means of the springs, and means connected with the sole-piece and with the sling part for connecting the device with the leg and knee of a person.
In the drawings, Figure 1 is a perspective showing my improved device as applied to use. Fig. 2 is a section through the device. Fig. 3 is also a section at right angles to that shown in Fig. 2. Fig. 4 is a detail perspective of one of the springs.
l represents the bottom part of the sole or base piece, the same being provided with side Walls or flanges 2 2 and With alip or flange 3. In the free edges of the flanges 2 are formed sockets or bearings for rods or shafts 4 4. Loops or yokes 5 5, each formed with two spirals 6 6, having ends 7 7 extending from the spirals, are connected with the side flanges 2 2 of the base-plate by means of the rods 4 4. The rods extend through the spirals in the yoke and the sockets or bearings in the edges of the base-plate. These yokes or loops extend vertically from the upper edges of the side walls of the base, and the ends 7 extend downward and bear against the flanges of the base-plate, as shown. These yokes or loops, with their spirals arranged as illustrated and described, vconstitute springs adapted to yield and give under variations of pressure or weight upon the sling or pad proper 8, which is hung upon and sustained by the loops or yokes. Vhen the base=plate is made of pressed steel or other sheet or plate metal, the side walls will also give or yield in some measure under pressure applied to the sling or pad proper. As a means of securing this pad or device to the knee of the user I provide a strap 9, which passes around the calf of the leg, the straplbeing attached at one end to the sling and secured at the other end by means of a buckle l0. To the front lip or iange 3 I attach, by preference, a web 11, which when applied to use closes the front end of the device and thereby prevents the admission of dirt or sand or anything of the kind from collecting on it or the base-plate or sole between the flanges. The lip furnishes a convenient means for the attachment of this flap or web by means of rivets or otherwise. The web furnishes a base or means of attachment of a second strap 12, which is drawn around the leg of the user just at the bend of the knee and secured by means ofafastening device 13. Also attached to the ilap or web l1 is another strap 14, provided with a safety-pin l5 for connection with the garment to hold the de vice rmly in correct position against the knee. The straps referred to are by preference made of elastic webbing or like elastic substance for the comfort and convenience of the user. vided Withperforations at the bottom, and a woodenv or other subbase may be riveted or otherwise secured to the base described Whenever found desirable.
The device Without any subbase or attachment will hold the knee away from the floor or ground a sufficient distance to ordinarily keep it out of water or dampness; but for some uses and in some localities it may be desirable to have the subbase attachment.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is;-
