Specification of Letters Patent.
Application filed May 1, 1911. Serial No. 624,285.
I to the accompanying drawings.
This invention relates to improvements in heels. for boots and shoes, the object of my invention being to provide a heel of improved construction which embodies elastic cushioning balls which are mounted in vention being to provideimproved devices 2o sockets with which the heel is provided and -which serve to give elasticity to the heel so as to relieve and prevent fatigue of walking and standing, another object of the inof this character which are extremely cheap and simple and are very strong and durable. In the accompanying drawlngs Figure 1 is a vertical longitudinal sectional view of a heel constructed in accordance with my invention; Fig. 2 is an-inverted plan of the same; and Fig. 3 is a transverse sectional view of the same on the plane indicated by the line H of Fig. 2.
- My improved heel is made ofa suitable number of layers 1 in which are formed sockets 2 which correspond in size and shape with cushioning balls 3 and serve to receive the said cushioning balls and nearly. cover them, the lower side 1 of the cushioning balls'being exposed and caused to project slightly below the bottom of the heel as indicated at 4, These cushioning balls are elastic and 'are, in practice, made of rubber. Any'suitablegnumber of the balls may be provided-according to the size of the heel and the balls may be of any suitable size. Five of; the said balls are shown in the heel for the purposes ofthis specification. The
. cushioning balls may be turned slightly in their sockets from. time to, time as may be required to present new surfaces below the heel, as thecuslnoning balls wear, but the cushioning balls do not turn casually in their sockets in walking as when-the heel is placed on the groundthe cushioning balls are compressed vertically to some extent by the weight and forceand hence tend to correspondingly expand horizontally and grip the surface of the socketsin which they are mounted, such gripping action effectually preventing the turning of the cushioning balls and hence there is no tendency, whatever, in my improved heel to slip. On the contrary, the cushioning. balls not only re; lieve the concussion of the .heel and correspondingly reduce the fatigue of walking and standing but also, by frictional contact withthe ground, or other surface, prevent slipping. 1
' It will be observed upon reference. tothe drawings that the sockets are partially made in the layers of the heel and it will be understood that the cushioning balls may be removed fromtheir sockets byfirst detaching the layers of the heel from one another. The layers of the heel are secured together in the ordinary way by nails or other suitable means. V
Having thus described my inventionI claim:
1. A heel having spherical sockets open on their lower sides at. the bottom of the heel and cushioning balls fitted in the said sockets andhaving their lower sides exposied and projecting from the bottom of the bee 2. A heel having spherical sockets open on their lower sides at the bottom of the heel and cushioning balls fitted in the said sockets and having their lower sides exposed and projecting from the bottom of the heel,
said cushioning balls being made of elastic Patented Dec. 2,6 1911.
