Specification of Letters Patent.
Patented' June 3o, isos.
Application inea september 5, isos. semi No. 333,396.
To all whom 'it may concern:
Be it known that I, FREDERICK W. Liens- BERG, a citizen of the United States, and a resident of St. Louis, in the State of Missouri, have invented certain new and usefullniproveniente in Shank-Stiii'eiiers, of which the ollowino' is a full, clear, and eXactdescri tion, sucsh as will enable those skilled in t e artito which it appertains to make and use the same, reference being had to the accompanying drawing, forming a part of this specication. i
The invention relates to. improvements in shank-stiifeners used in boots and slices.
`appended claims, .and illustrated in the accom anying drawings.
In the drawings, in which similar letters parts,
Figure 1is a plan view of a device em odying the invention. Fi 2 is a side elevation.
' 3 is a sectiona view on the line 3-3 of `he sti'ener' is formed of a plate of thin 4-spi'in rnetal comprising two members, A
insvv and respectively, which are oined by the centraly integral connection The two members are separated at their ends by the wedge-shaped openings D which permit i* 'them to move independently of each other .to a. considerable extent.
The stitfeiier is bent transversely along its median line extending between the apcxes of the openings D, as at E, to form an obtuse' angle between the two members. The latter are bent longitudinally to different degrees of curvature, the member A beinor comparatively shallow and the member il deep.
he shallow curvature of the member A tits the comparatively low arch of the outer side o'l' the foot and the deep curvature of the member B fits the comparatively higher arch on the inner side of the foot. ln its position in the. shank of the shoe the member A is horizontal transversely to adapt it io the fiat "oiitci' part of the foot and the member B is bent upwardly in a transverse direction to comparatively,
conform to the inclination of the arch on the i inner side of the foot. Also the member A is of such width as to accommodate the fiat outer art of the foot and the member B, which iswider, is adapted to the width of the arch on the inner side of the-foot. The outer edge of the member A is straight to meet the straight outer edge of the foot and the outer edge of the other member is curved to follow the curved inner side of the foot. 'When in position the member A springs in a vert-ical direction only to support the ilat outer part of the foot in the direction in which the' pressure is applied, and the member B springs both vertically and laterally to take up the pressure exerted by the inner arched part of the foot.
Having thus describedl my invention, what I claim and desire to secure by Letters-Pat ent is,
.1. A shank-stiifener formed of a plate of thin spring metal comprising two longitudinally curved members oined bv a central integral connection, sail` stilfeiier being bentalong its median line/to form an obtuse angle between the members.
A shank-stiielier formed of a plate of thin spring metal comprising two members joined by a central integral connection and separated at their ends b wedge-shaped openings, said stiffener being bent transversely along its median line to fornran obtuse angle between the members, and one-ol said members having a comparatively shallow longitudinal curvature and the other member having a comparatively deep longitudinal curvature.
3. A shankestilleiier formed of a plato of.
thin spring metal comprisingir two members joined by a central integral connection and separated at their ends by wedge-shaped openings, said stifle-ner being;r bont translvei'selyalong its median line to form an obtuse angle between the members, and one of ica
