SHOE HEEL BASE Filed March 7. 1929 Y//Wmww 4f ATTORNEY.

Patented @et 27, 1931 PATENT VINC-ENT MENINNVO, 0F NASHUA, NEW HAMPSHIRE SHOE HEEL BASE l Application led March 7,

This invention relates to what are known as the heel basesof shoes.

In the present day manufacture of shoes, especially those equipped with rubber heels, it is customary to use what is known as a heel base between the wearing surface of the heel and the heel part of the outerand inner sole. Y These bases have a substantially flat face at the bottom where'the wearing part of the heel is attached and at the top face are made concave. The concavity isproduced' either by attaching around the outside edge of the top face at the back and sides, a rand, or by making al blank with parallel top and bottom faces and then gouging out the top to form a concavity of the desired depth and shape.

The first class heel bases are made of one section or lift of good real leather around the edge of the top face of which is cementedl a rand also of first class real leather. As leather is expensive and there is considerable loss in cutting, while this makes the best base, it is expensive.

Heel lifts have been made by taking a large number of pieces all of substantially the same thickness and putting them together like a puzzle, then cement-ing over the entire top a thin piece of material, thus holding them together.

Heel bases have been made by taking a number of pieces of leather or other material I of various shapes and sizes and imbedding in them a metal together. i

Other heel bases have been made by providing certain parts of uniform size and associating with them a third; partwhich may plate to hold the whole outt vbe of variable sizes to make heel bases of different sizes and holding all together by a complete lift of' some other material which shows at the edges. I

Other heel bases have been made of leather board with the top gouged out or with some leather board lused. in connection with a leather rand, but leather board soaks up watervlike a sponge and is very objectionable in the finished shoe, although it is cheap.

lThe objection to various built up heel bases is that the operation 0f taSSeIIlbling 1929. Serial No. 345,059.

them is slow and therefore expensive, and in some of them there are too many breaks which show on the outside of the heel.

The purpose of this invention is to provide a heel base of the rst quality made entirely of leather sections, such sections being of such character that they can be very quickly assembled and held together until a leather rand is attached, and so that when attached they are very firm and will not separate nor lose their shape in any respect.

I accomplish this by using two sections only, having adjoining straight edges and over the bottom face along the middle I cement a connecting strip of sheet material while, preferably, the rand is afterwards cemented around the outside of the top edge of the sections. Thereby the rand helps to hold the whole organization together especially if it is on one side and the patch on the other and when the base is assembled with a wear- -pressure of the heel compression machine and the patch never appears on the edges.

Assembling with only two pieces in aheel machine can be done very rapidly because a ile of sections can be in reach of each hand and when two sections are brought together in a form or chute, the strip is instantly placed over the junction, pressure is applied and the operator is ready for another layer. In the drawings, Fig. l is a vertical sectional elevation showing certain parts of a shoe with my base, and a wearing heel attached thereto.

Fig. 2 shows the two sections of a heel base ofmy preferred construction placed to gether before the connecting strip is cemented in position.

heel base, and Gr is the .wea-ringv F ismy surfacev which, as shown, is a rubber heel of thewell-'known type. This heel has nail holes indicated by 10 in which the heads of the nails H which tasten G and F to outer sole C are buried. Ordinarily there are about nine nails, the ones shown in Fig. 1 being thenails at the `front and the back.l l

In 'my Vpreferred type of heel base, I cut out of scrap leather, all of the same thickness,

similar sections 3() and 31,l each having a rstraight edge 32 or 33 andA each having in corresponding positions 'the two half nail holes 34 and 36 fand. 35 and 37.

It'niakes nofdiiierence 'whether the straight edges of the two sections are put together each with ythe grainV or fleshlside up, or one with `thegrain and one with the-flesh. The fronts Y 42'over the middle of the adjoining 'face por- 501 tions vof the'sections, I prefer to' use some type of strong glue which Ywill harden quickly and `which will remain relatively hard-so that the two sections' can be readily handled vwithout bending or cracking.

Ithentake aleather rand 45 of thev usual "form which tapers in height from the outside to the inside and curve it around the top outf' Y side edge of the two unitedsections,' cementing-it position preferably v'with a "cement:v

or glue which is somewhat flexible.

The assembly is now held togetherA bythe i Slp 42 on the bottom` face, andthe randy on the topfac'e.l Y .irv VBeforeattaching the rand,or during that 'Y process, 4or afterwards, I prefer tol subject Y. the sections 30 and 31 to great pressure where- 'the other hand.V

' 2. In a shoe'heel vby the connectingv strip 42 is practically imbedded in the sections 30 and 31, thus making the bottom face 130, as shown in Fig. 9, practically level and fiat, while whatever slight distortion there may be of the top face 131 is immaterial because it is takenl up by the curvature of the rand 45. f Y.

With the above construction, the only joint which shows is at 40 because the Vjoint 41 at the front is entirely out ofsight. The nails such as H, H when driven in pass through .the'nail holes 34, 35 and 36, 37 respectively and pass through strip 42 or not, according to its size. By .providing these nail holes,

the tendency of the nails to separate the two sections is avoided'. f f

In Fig. 10, I show an' assembly of two sec tions 50 and 51 whichare not similar but which dohave the-corresponding straight edges 52 and 53 where theyV are putY together. Over'the middle ofthe adjoining face portions, Ivr cement the 'connecting strip 54 of thin material and except that I use no nail holes, the layer formed by the two sections is ythe same as that shown in Figs. 2 andz3 vand to its is attached a rand in a manner` similar to what is shown in Figs'..1`, 8 and 9.

In assembling this type of layer, Yit saves time to have a pile of sections 50 in reach of one handand apile of-sections 51 in reach of As shown in Fig. 11, I may attach a strip 1 42 on the same face with rand 45 but in such case, therev is aslight tendencyv for the'V bottom edges of the sections at 41 to separate.
