To) all whom it may' concern: Be it known that l, JOHN McBRnAR'rr, a citizen of the United States, and a resident of Rosemont, county of Montgomery, State of Pennsylvania, have invented certain new and useful improvements in Shoes, of which the following is a specification.

My invention relates to an improvement in shoes wherein an inner shock absorbing portion is inserted against the foot or very close thereto, so that the foot may have the the cushionthe-foot and the artificial cushion a substantially solid layer of leather and nails, or the lln addition to supplying the suitable parts which are to be used adjacent to said cushion, ll have inserted an arch supporter of new and improved form which co- {iexible pad and with the flexible pad supporter or container, later to be referred to, and whereby the arch supporter by influencev thereon of the shell or container serves to maintain the arch of the foot in proper conformation by maintaining the shoe beneath and to one side Lof the instep of the foot with suitable convexity. ln performing lthis \fi inction, the arch supporter isi/not bodily 'displaced laterally Ior longitudinally, nor is it flattened by pressure thereon, vbut it may be distended at the forward end as av result of pressure ap lied thereto without displacing the parts o the shoe inthe vicinity thereof. ln addition to a cover for the pad above referred to, lhave supplied a metallic heel cup which-fis of- Vsuch equivalent..

above mentioned arch supporter and of such :depth as to contain the flexible pad or supl0 port and also repel all nails and the like Ifrom passing into and through said shock resisting material. j

Reference to PatentNo. 1,148,604, dated August 3, 1915, issued to myself7 shows many similarities between the shoe manu'- factured under that patent anda shoe constructed in accordance with my present invention. However, the differences which l have introduced into the construction later to be described, are such as to introduce very Aradical improvements in shoes manufacprovenient which l have tured in accordance withsaid patent.

One important and very essential im'- efi'ected in my latest form of shoe construction residesv in the fact that said form can be repaired, as

Vpairedy shoe,

extent as to cooperate with the desired, and repeatedly, and the inner surface vof the shoe at the heel is always maintained assmooth las the lsurface of the new shoe. This featurer is most important because repaired shoes are becoming more important commodities during t the present periodl whenJ the price of shoes has been tremendouslyv increased. To some who have heretofore worn repaired shoes the absence of the roughened surface of the heel and of thenails themselves after a little wear, which are necessary incidents in connection with the attachment 'of the heel to the reisga boon and a distinct advantage. 'llo those who never have worn repaired shoes heretofore on account of tender feet and many other reasons but who are now, or presentlyr will be, obliged to, resort to repaired shoes, the smooth heel of my improved shoe after repair will appeal as a material advance in the manufacture of shoes.`

It will be atA once recognized that shoes fitted with rubber heels also become rough and uncomfortable at the inside of the heel after repeated renewals of the rubber heel owing to the necessity of driving the fastenl ing means and clenching the nails in the vicinity of the heel of the shoe, but com'- plete relieffrom this fault is `obtained in my improved form of shoe which also contains the provision for the absorption of shocks possessed by the rubber heel.

,ln the shoe later to be described, the nails driven through the heel to' attach it to the repaired shoe canv never reach the cushion member as they are repelled bythe pad container and clenched at a distance from the space occupied by the heel of the wearer.

ln addition`to overcoming the above men- `movably. As a result of the construction embodied in a shoe which shall later be de scribed, l have effected an improvement in a shoe having aninner cushion forvthe foot which can be repeatedly repaired without v tioned circumstances, l nd it possiblein injury to the shock absorbing pad, and there is alsov present in this construction ,ashoe in which the nails fastening the heel thereonto cannot project into the immediate vicinity ofthe foot of the wearer.

rlhere is still another advantage in that the shoe which l have produced may be made upon a simple wooden last, without adding .thereto steel lplates to form a protection against nails or otherl fastening means at the heel thereof, which are continuously present to repel the points of the nails used to fasten the heel to the inner sole.

An improved heel construction, effecting a saving in leather, `also resultsfrom the form of shoe proposed by me, in that l shape the rear of the shoe so as to bring the level of the foot to the same level of the foot in thelordinary shoe, and,therefore, in making room for the thickness of the pad, l remove a portion of the heel and thus make its volume less. l construct the heel which l' shall use upon the shoe contemplated by me out of smaller pieces of leather than are Ordinarily employed in the best quality of heels. In this way a 'considerable saving in sole leather or equivalent materials in themanufacture of heels is effected. Nevertheless, l can replace the wear resisting outer layers of my heel at will and thus am not obliged to sacrifice the qualities of the,

present style of heel in order to effect the saving in material referred to.

By the `,cooperative use of the shell container and the particular form of arch supporter togetherl with the action of the interposed inner sole, I have introduced a desirable form of arch supporter which is firmly positioned and maintained in place so `as t0 perform the function assigned to it in an advantageous manner.

ln the drawing accompanying this speciv fication and relating thereto, Figure 1 shows a well known last lwithout a metallic shield at heel, and placed thereon some of the members which I have introduced 4into the construction of shoes; Fig. 2 is a fragmentary view and shows `the same parts in place and added thereto an upper with lining, an

linner sole and welt, and my improved arch supporter; Fig.` 3 shows another advance in the manufacture of the improved-shoe and presents thepshoe of my invention in a fragmentary view with the outer sole fastened to the other parts and with a heel fastened in place; Fig. 4 shows a vertical longitudinal section of a shoe manufactured in accordancewith my invention and has a foot depicted therein so as to showv the combined arch supporter function of the pad and arch supporter plate; Fig. 5 is a sec.- tion on line 5 5 of Fig. 4showing the h eel attached to the outer and inner sole, the shell, pad and cover, and the upper, lining and counter all in section; Fig. 6 shows, in perspective, the form of arch supporter used by me; Fig. 7 shows, in perspective, the shell, the inner sole and the arch supporter as a unit andin coperative relation; and

Fig. 8 shows a detailed section through the.

forward part of the shell which includes a section of the inner sole and arch supporter, adjacent parts being omitted. y

lThe shoe made in accordance with my invention is best described by a showing and a description of the action of assembling and fastening together the various parts of a shoe rather than to describe the parts in place in a view like Fig. 4. For instance, a last 1, of selected size for the shoe intended to be made, is used upon which to unite the various shoe parts, the upperv 10, welt 11 and lining 12 of the shoe are omitted for the sake of clearness, but they appear in Fig. 2 in place and connected to the inner sole 5. Upon the heel of said last 1is placed the cushion cover 2 and upon and above the cover is located the cushionlorshock absorbing member 3. While l intend'to utilize a 4cover 2 or the equivalent for the purpose of pad 3, which also holds the pad firmly 'in place, .Il also contemplate the construction and assemblage fof parts wherein the pad has no cover such asshown by 2 in the drawings but may have an outer layer incorporated therein which shall serve as a smooth surfacing wear resisting member. Under such conditions the pad 3 and shell 4 will be united by cement or in some equivalent manner and means will be provided for holding the pad in place other thanwhere it will be fastened to said shell 4. W'ith this arrangement l may also use' a pad which 4shall not need an upper surface layer because the material of which it is composed is homogeneous throughout and is also suitable for contact with the footof the wearer inclosed in a stocking. .ll have experimented with a number of materials for use in this pad and have found many satisfactory. l contemplate the use of such material as shall retain its resiliency and continuity and be long' wearing. Necessarily, the upper surface of the vcushion-3 is smooth and substantially flat, so that the foot of thel wearer shall not be inconvenienced by-any distortion of the surface thereof, der portion of the `cus to provide a sufficient depth to said pad ,and

thus permit the insertion beneath the heel of form, its inner surface is substantially in contact with the pad throughout the entire* concave 'surface of said shell.' rlihe concave whereas, the un- 4' Y ion or pad, now upper-1, most, has a. considerable convexlty 1n order? and being of dished l l fastening means.

Laramie surface is preferably polished in order to more easily turn and clcnch nails and like Cement or other means may be used to more intimately unite the lshell and pad. The next step is to lay an inner sole 5 upon the shell 4 and to fasten .the same at the Waist and ball ofthe last by tacking or by any other suitable means. The' next step is to fold the cushion cover 2 over the margin of the inner sole 5 at the rearinost portion thereof1 so that the inner'sole 5" is interposed between the shell 4 and the turned over portion of the cover 2. When this is done the upper 10. is then pulled over at front and rear andthe usual lasting operations are carried outv in which the upper and Welt 11 are brought -into proper position relative to the inner sole and are tacked in place on the last. 1 around the edge thereof. At the heel, the upper and the( cover are neatly pulled 'over onto/the last and tacks are driven to hold them, and tacks are placed near the edge .of shell 4 and clenched overonto the shell to hold it in place on the last, then the cushion, cover shell and upper are correctly positioned and held in place over the innersole.

As the inner sole 5 is -suitablychanneled near itsedge, and as the Welt 11 is sevved to the inner sole by sewing through the iap produced by channeling when the sewing of the inner sole and Welt has been carried out andcompl'eted and the parts are properly united, the tacks fastening the inner sole and ing of the other parts are removed.

When the parts are unitedgas just described, my improved form offfarch supporter is i of the inner sole and by reason of the driv# ttangs 8 and 18 thereen into ,the

inner sole he arch supporter 'is semixedly. positioned.- The tangs 8 :are dimen- 'long enough to pass sioned so as to solidly embed themselves in the material of the inner sole but are not altogether therethrough and into permanent contact with the shell 4. The tangs 18 arefof somewhat shorter length thangthe tangs 8, and theyare made shorter.

sothat when the arch supporter 6 is in intimate contact with the inner sole 5 the tangswill not 4pase thrcugh the inner sole 5 but .Will simp'ly'embed themselves therein and be firmly held thereby. A tang 19 is shown en the arch supporter 6 and it lsgiven practically the 'same dimensions as the tangs 18; it is turned in a direction opposite-to the tangs 18. rllhe purpose of the tang 19 is similar to that of tangs 18 for it is intended to be forced into the material of the outer sole in a manner later to be described. Referring additionally to the tangs 18 and 19 it should be noted that While l have shown three in all, ll contemplate the use of a cushion positioned upon the upper surface ,2

. at 'piece of metal.

cannot move away Y l tion therein. The tangs also preventany ing a position over o and bend it into a flat condition.-

greater number and even of a less number as the case may be and l also intend to position themand form them in Avarious and different Ways.; l

ln placing the arch supporter 6 care is taken tolocate tit so that it shall have a definite positionV With regard to the shell 4 with which .it coperates and reference should therefore be made to Figs. 7 and 8 for a clear understanding of the relation of the arch supporter 6 'and the shell 4.

yBearing in mind that a left shoe is depicted in the drawings,.it Will be seen that the arch supporter 6 is carried as far as possible to the inner edge of the inner sole and theshell 4 and thereby is elevated at its inner edge 2O by reason of the fact that it lits about and on the curvature of the end of the shelli4. ln this position the inner edge 20 serves to force the inner sole`5 above it and tlie cushion 3y lshank of the shoe acts very `eectively as an arch supporter.

Furthermore, it should be noted that on account of the sloped surface of the shankof the shoe and also on accountof the fact that the arch supporter 6 is located as far as possible to the inside of the shoe the bones of the foot do'not bear upon the bent metal supe ort 6 and straighten lt out into "merely a ld he arched shape of the su port is also maintained due to the fact that the tangs 18 and 19 are solidly inserted into vthe inner and. outer soles and hence from their original positransverse displacement, consequently the bone of the foot at the outside edge ofthe foot, the metatarsus, is prevented from takthe arch supporter 6 llt should be understood that ll control the positionof the arch supporter so as to prevent the edge 20 thereof from taking aposil tion forming a continuous edge with the edge of the shell 4. llt is necessary to leave a margin 21r between the edge of the shell and the edge 20 of the arch supporter for the 'purpose of accommodating the seam which is necessarily found at this place. i

l have, therefore, formed an efliclent unitary device `,comprising the shell 4, the inner sole 5 and the arch supporter 6 Wh1ch unit is clearly shown in Fig. 7. At the broad end of thearch supporter and between iso ' of the shell 4.

the tangs 8 I have formed an arcuate or cut out portion permitting of a close connection between the parts as well as permitting the Vcentral thickened. portion of the shell'4 to is made only on the points and the'tangs there is no tendency to displace adjacent l parts.

I have also effected a suitable relation between the shell and the arch supporter by off-setting the arch supporter just forward of the arcuate or cutout portion referred to to form the portion 22. This part 22 ofthe arch supporter is placed just over the shell 4 and adjacent to the edge thereofgand forms a bearing surface tendingv to aline the arch supporter with the general direction of the shell 4. In order to adjust this alinement the ends 7 may be raised or depressed'as `desired.

In view of the foregoing description it is evident that the unit shown in Fig. y7 represents a new and important construction in shoes for through the agency of the inner sole and the outer solewhich hold the arch supporter 6 in place, the shell 4 acts as a foundation' member upon which to position and hold in place the arch supporter 6 which is thereby given a slant to form the sole of the shoe to the shape of the arch of the foot. It is manifest that without the shell 4 there would be no chance of fixedly holding the arch supporter 6 in the slanted position and it should be noted that the inner sole inter posed between the shell and the support cooperates with both to form a rigid but ieX- ible arch supporter.v

The arch supporter 6 is shown with a particular form and is showny arched but there are no special limitations on these detailsf/ One side, namely 20, is mad/e straight so as to permit the arch supporter to be moved to one side of the shoe, namely that side toward the other foot,andis hollowed out on the outer side to permit the metatarsus to pass thereby and not press thereupon.

The outer sole is then applied to the parts of the shoe on the last and after fitting it into proper contact with the inner sole the tang 19 on the arch supporter 6 is driven into place and the outer sole is temporarily fastened to the inner sole over the arch supporter by tacking and later sewed to the welt in the regular way. The finishing processes consisting of sanding, blackening and the like need only the slightest reference thereto. The foregoing functions of attach-- ing the upper and lining to the inner sole and later to theouter sole are well known and they are not materially different or modified in connection with the making of a shoe embodied in my invention.

Possibly reference should be made to the particular construction at the heel 9 of the shoe where the upper 10, the lining 12, inner sole 5, counter 1 4, and thejquarter 15 are fastened together by tacks or other suitable means and at thesame time the cushion cover 2 is fastened firmly in place. In addition to the fastening of these parts, the outer sole 13 is brought over and fastened through .the portionsabove mentioned, said fastening means being headed over by the nail resisting container and clencher 4.

After the outer sole has been fastened to the other parts, nails 16 or other `fastening means are driven through the heel 9 and through both the outer and inner soles and are clenched at their points against the nail resisting container 4. It should be noted that the heel 9 used by me in connection with the shoe above described comprises a relatively lesser quantity of heel material than is present in the shoes as customarily made. This is due to the fact that below the substantially flat surface `of the foot there is interposed the shock resisting pad 3 which should be of substantial thickness and which is held in the convex s110114 above referred to. The depth of all of these parts necessarily displaces the position of the-inner and outer soles 5 and 13 downwardly and consequently leaves a lessened space to be oz'cu'pied by the heel 4 proper. rIhis is particularly so at the forward portion of the heel. Additionally in forming the heel described, I have introduced a new feature into the construction of shoes, namely that of arranging a space for a pad or like member and protecting said space and the shock resisting member introduced therein 'from nailsn and other means used in fastening the parts of shoes together. For instance, I believe it is entirely new in the making of shoes to employ an unshod unmetalled wooden last such as 1 and to form adjacent theretoa space into which a pad member l3 shall be inserted which shall be either coveredor uncovered 'and then proceed to cornplete the shoe and fasten the parts thereof on said unprotected last and have a shoe which may be repaired without deteriora ion of the pad. It is further new in the manufacture of shoes to provide a-space in said shoes for a pad by the use of a nail clenching member used in conjunction with an ordinary last and this I contemplate as well as what has been already described in detail and I may say that I have in mind broadly Latiano@ all'w'ays .offorming such a shoeupon any` last of ordinary form either shod or unshod.

And in this connection l will elaborate upon Y what vhas just been referred to as an improvement upon my Patent No. l,i4l8,60l.

ln that patent it is clear that a special last Y and partsconnected thereto are necessary inv order to forni a shoe having such a recess orY `space for the insertion of a shock absorbing member. f

' Referring to Fig, and bearing in mind the anatomy of the' human foot, it'will be noted that the thickest portion of the pad 3 is almost exactly in line with-the os calcis which is the lower `prominent extension of the bone at the heel. When the weight of the .body is thrown upon the foot there is cons' erable weight borne -by the os calcis withi a limited area at the heel with theresult that the cushion or pad '3 beneath the os calcis is com ressed more than it is under the arch 17. onsequently due to the new -di'erence in level between that of 'the heel and that of the arch the pad se es to act automatically as ansarch supporr 'as wellV il shouldas a shock absorbing member. also be noted that this action .of the pad in serving as an arch supporter becomes more and more important. as .the load l upon the os calcis increases and the pad always adjusts itsaction asian arch supporter to' the ln the foregoing l have, for the sake of directness and clearness of'description, re-

ferredto the specific parts and a particular manner of connecting said parts and l therefore wish to state that l' contemplate -all of the various means of accomplishing the result which has been described and shown in a' particular way in the foregoing. -Under no circumstances do l, intend to 'limit my in-v vention to only that which has been described by me.V
