Specification of Letters Patent.

Patented Aug. 14, 1917.

Application inea January 22, 1915. serial No.'s,791.

To all whom t may concern.'

Be it known that I, HENRY W. HALLEY, a citizen of the United States, residing at Hutchinson, in thc county of Reno and State of Kansas, have invented certain new and useful improvements in lnsoles, of which the following is a specification, reference being had therein to the accompanying 'draws ing.

My invention relates to insoles for shoes and has for its principal object to distribute and hold antiseptic or other material in a shoe in such manner as to produce maximum effect with minimum waste. jects will suliiciently appear in the description hereinafter.

In order to attain my object, I provide an insole with small wells or partial'perfo-y cate their stockings, at least order to prevent undue friction and heatm rations distributed with approximate uniformity throughout its upper surface. These wells or perforations are in practice filled with the desired material. The nature of this material may be varied according to relquirements without departing from the spirit of the invention. Thus, an antiseptic powder may be distributed and held without waste in the little wells, or plain talcum, or soapstone powder, or grease for pedestrians, or other medicaments of various sorts, dry or not, and it is to be particularly observed that since the wells are inthe upper part of the insole and do not extend through the material, the medicament is retained where it is needednext the foot, and does not underany conditions reach the structure of the shoe sole. This is particularly desirable Where a material is employed which might soften or rot the. stitching. Itis not unusual for those engaged in sports such as golf, or in Walking .for

on the soles, in

y with constant formation of blisters. Obviously, howevenafter the sole of a shoe has been greased in this way and the grease rubbed in,` it can only be used for purposes requiring grease, and the saine may be said of medicaments of any kind. With myI invention on the other hand; the sole may be kept thoroughly lubricated by deposits of grease or medicament in, the little wells, and if 'it be desired to ruse the shoe afterward with different stockings or for a dilerent "purpose, it is only necessary to remove the insole which hrings with it all of the grease,

Ancillary obconsiderable periods, to lubril powder, o'r whatnot which has been employed.

My invention is illustrated in the accompanying drawings in which- Figure 1 is a'plan view of an insole constructed accordin to my invention.

Fig. ,2 is a long1tudinal section on the line .7iof F ig. l.

Referring to the drawing, the insole 1 is provided with small wells orisemi-perfora'- tions 2, which it will be observed are distributed with approximate uniformity throughout its surface. There are more of these perforations under the ball of the foot and directly under the instep, partly sole and partly is exerted on t the sole.` f

In constructing this insole, the holes may" be pressed or drilled or otherwise produced in a solid body of material such as leather, or as indicated in Fig. 2, they may be' tothe fact that no pressure e sprlng or arch vportion of heel than under the.l due to .the contour of the inmaterial, and not through the other.

In makin a two-part insole, the parts may be punc ed either in two o erations or in one, that is to say either with se arate punches or a combination punch. In t e latter case there will have to be a change in the tool after the requisite number of rforated layers are produced, so that the alance of the4 layers will be turned out solid..Y These are then matched together in pairs, and cemented and stitched or otherwise secured together, so as to form a solid integral body with the wells-or perforations extending only part way through it.

In practice, powder is'placedi'in a shoe containing this insole and the shoe shaken or moved about to distribute the powder over the insole and thereby fill al the wells. When this has been accomplished, thel sur- I.plus powder may be removed and in yorder I have found that when my improved insole lis used without antiseptic powder, it has ceri 'tainberieicial properties one "owhich is that it appears to afford rest to the foot. 'This may partial apertures, which permits ready dis tribution and evaporation of moisture and vapors. Another beneficial property is that the small wells with solid or hermetically closed sides and bottoms' create suction between the foot and the insole and aord a greater' coefiicient of friction or a greater 'resistance to longitudinal motion of the foot than an ordinary smooth polished insole. In

`1li walking. with heeledfs'hoesof ordinary construction', 'there is a 'tendency for the foot to tbe thrown forward in the shoe with the result that pressureis exerted not only latern i ally in acompressiv'e manner upon the small bones ,of the toes and r -but also rearwardly against the arch of the the ball of'the foot,

", instep; andifisuch pressure maintained, Athat is to say",=1f walking" 1s persistedin with Shoes that"` dof not allow free movenientof i 2B the bony arch-of the instep, there will be a.

. t tendency lorth'is' arch to break down,

yducing what is known as "flat foot. This electhas beenvery Anoticeable 1n womens heels,`also infmens shes'when the so e due, tosonie `rentilating effect of the position unit.

for the purposes stated, and I contemplate as part of my invention all modifications of the structure ormethod herein described which fall 'airl y within the scope of the appended claims.

'hile I have mentioned leather as a material for my insole, it is to be understood that other materials may also be employed without departing from the purview of the invention. Among the materials which would he suitable tov meet general or special conditions I may mention indurated fiber, compressed paper or fabric, andcombinations otl materials, whether in separate layers, each of a single material, or in one com- As a means` for applying medicaments to the feet, my device may even i shoes' of isome types,` such as lare fitted with varewornJ" The ell'ect'ris' never absent fromv anyshoes having heels, because each step forw/rd in the rolling motion.l v4of walking,` 23E brings a forward impulse t'tlie foot swing- `onkthe ball, while the shoe/is helil haelt byfction against the ground?

Ido not broadly lclaim perforations forthis purpose, as I am' awarethat completely perforated soles havel been used fordiferent purposessuch as that of Ventilation. I de claim;h however, the use of partial perforations or wellsiin the insole e i be used without a shoe, being bound to the foot in any suitable manner, or it may be provided with heel and toe straps or inclosures, and beused itself'as a sandal or slipper.

Having thusdescribed my invention what I claimV and desire to `secure by Letters Patent is:

1. An insole having a solid continuous body of substantially uniform thickness provided with a plurality of relatively small depressions or wells with solidly closed sides and bottoms, distributed over the bearing;r surface upon which the users foot will rest, and suliieiently tight and proof against leakage to create suction kbetween the foot and the. insole, to receive and retain medicaments 9 i `when desired, and to prevent saidmedicaments when employed from passing through the insole. Y

f2. An insole having-a Solid body provided wilh a plurality of relatively small depressions pr wells in its upper. side, with solidly closed sides and bottoms, said wells being?r filled with antiseptic material.

V3. An insole haring a solid body provided with a plurality `of depressions or wells in its upper side filled with antiseptic powder.

In testimony whereof I affix my signature s in presence of two witnesses.
