To all whom it may concern:
Be it known that I, CATHERINE A. WLIAMSON, of St, Louis, Missouri, have made a new and useful Improvement in Shoulder-Braces, of which the following is a fall, clear, and exact description, reference being had to the annexed drawings , making part of this specification, in which--
Figure 1 is a view in perspective, showing the improved brace in position; Fig. 2, an elevation, showing the front ends of the waistbands and connecting-straps; and Fig. 3., a view of one of the back-pieces.
The same letters denote the same parts.
The present invention is an improvement in that class of shoulder-braces wherein back-pieces or long spinal supports extending up and down at each side of the spine are used. It has relation partly to the construction of the supports and partly to the means used in fastening them in position.
Referring to the drawings, A A represent the supports. They are in the form of flat strips extending from a little above the shoulder-blades downward to the lower part of the back, and as long as can be comfortably worn, and being spaced sufficiently apart to prevent any direct pressure upon the spine. These strips constitute the main frame of the device, and they are usually made of steel; but in place of being imperforate, as hitherto made, they are perforated throughout, as shown at a a, Fig. 3, the aim thereof being to prevent that part of the body against which the supports come from becoming overheated--a difficulty occasioned when the supports are closed or imperforate, and which is removed by means of the openings in the supports, as thereby sufficient vent is provided for the passage and dissipation of the heat.
The perforations a a may be of any suitable shape.
The supports at the shoulder-blades are united by a flexible but inelastic tie, B, which sustains the upper ends of the supports against the strains of the arm-pieces C C. The latter extend from the supports, or rather from the casings in which the supports are usually held, over the shoulders and underneath the arms of the wearer and back to the supports, having an adjustable connection, c c, therewith, and opposite the lower end of the tie B.
The arm-pieces are partially elastic, the straps c c and also the parts c' c' being elastic. In front the arm-pieces are padded.
The supports A A, from the shoulder-blades downward, are united by elastic ties D D, several ties being used and spaced apart to provide air-openings d d.
E E represent bands arranged at the waist of the wearer, and extending from the supports A A, so as to nearly meet at the front of the waist, the connections being completed by the elastic straps e e e, Fig. 2. The hands E E are flexible and inelastic. They support the sides of the body and serve to hold the lower ends of the supports in place.
In operation the braces are adjusted in position by suitable tightening the straps c c and e e e. The effect is to straighten the shoulders, relieve the chest, and support the back and sides, but in such a way as not to interfere with any movement of the arms or body.
1. The combination of the supports A A, the flexible inelastic tie B, and the partiallyelastic arm-pieces C C, substantially as described.
2. The combination of the supports A A, the flex inelastic tie B, arm-pieces CC, the elastic ties D D, baud E E, and straps e e e, substantially as described.
Witness my hand.
