SOLE-LEVELING MACHINE] SPECIFICATION forming part of Letters Patent N 0. 722,889, dated March 17, 1903.

v Application filed A rilZS, 1902: Serial Nth 104,248. on model.)

To all whom, it may concern:

Beit known that I, BENJAMIN PHILLIPS, a

citizen of the United States, residing at Lynn,

in the county of Essex and State of Massachusetts, have invented certain new and use The present invention relates to an improvement in sole-leveling machines.

The object of my invention is to reorganize and improve sole-leveling machines, and particularly to produce an improved sole-level ing device especially adapted for use in leveling turned shoes. r

I am aware that it has been proposed to construct a roll for sole-leveling machines consisting of a series of cylindrical rolls loosely mounted in bearings arranged around a shaft which is adapted to be rotated by power and to level the sole of a shoe on the last by holding it against such rotating roll. Such roll, however, was objectionable because it did not fit the sole of the shoe to be'leveled, and it is desirable, as is well known to those skilled in the art, that the sole-leveling roll should conform more or less to the shape desired to be imparted to the solo by the soleleveling operation.

I am aware that sole-leveling rolls have been constructed consisting of a concaved surfaced roll which was adapted to conform more or less to the shape desired to be imparted to the sole, but in such construction the roll, being large in diameter, was required to exert a very v considerable pressure upon the sole of the shoe in order to level the same.

According to my invention I have mounted a series of concave rolls in hearings in a carrier adapted to be driven by power. These rolls are comparatively small in diameter and exert a pressure upon the leather which is greater per unit of area than would be exerted out thelnecessity of exertingagreat pressure upon the roll. Itis obvious that by the use of concaved surfaced rolls, as above described, there will be spaces left between the middle portions of such rolls, and I fill these spaces with shorter rolls mounted in suitable bearings between the middle portions of the longer concave rolls, thus providing a greater number of rolls for successively acting upon the sole in order to level the same. The smaller rolls, which may be termed auXil iary rolls, occupy the spaces which otherwise would exist between the larger rolls, which may be termed the primary rolls, and the resulting device, although it may be of use for leveling welt-shoes,is more especially adapted forleveling turned shoes,in which the pressure necessary to level the sole is usually considerably less than the pressure necessary to level the sole of a welt-shoe. I am also aware thatit has been proposed to make asole-leveling roll consisting of two sets of tapered rolls having their larger ends at the ends of the roll and their smaller ends extended toward and beyond each other; but my invention is clearly differentiated therefrom in many ways clearly apparent to those skilled in the art.

In the accompanying drawings, illustrating the preferred form of my invention, Figure 1 is an elevation of a sole-leveling roll embodying my invention. Fig. 2 is a longitudinal sectional elevation thereof, taken on so that the shape of the roll conforms more or less to the shape desired to be imparted to the sole of the shoe to be leveled. Owing to the concavity of the rolls 1 there exist considerable spaces between the middle portions of said rolls. I have provided the auxiliary rolls t, which are located in such spaces, being mounted in hearings in the disks'5, secured to the shaft 3. The rolls 4 are preferably made of the same size as the middle porpreferably be rounded off, as shown, so that such ends shall not mar the sole of the shoe during the leveling operation. The disks 2 and 5 are conveniently supported upon the shaft 3, as follows: A sleeve 6 is placed upon the shaft 3 between the disks 5, and thus maintains said disks at the proper distance from each other. The disks 2 and 5 are provided with hubs 7 and 8, respectively, which conveniently come in contact with each other to maintain the disks 2 and 5 at the proper distance apart. In order accurately to maintain the parallelism of the rolls 1 and 4 to the axis of the shaft 3 and to maintain said rolls in proper position with relation to each other, the disks 2 and 5 are secured to the shaft in any suitable Way, as by means of the splines 9. These devices constitute a carrier for the sets of rolls, and while any desired form of carrier may be employed in carrying out my invention the carrier illustrated in the drawings is a convenient and efficient means for this purpose.

It is to be understood that my invention is not limited to the illustrated embodiment of my invention, as the same may be embodied in other forms Without departure therefrom.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States- 1. A sole-leveling device, having, in combination, a carrier, a set of primary concave rolls revolubly mounted in said carrier and a setof shorter auxiliary rolls located in the spaces between the primary rolls, substantially as described.

2. A sole-leveling roll, having, in combination, a set of primary concave rolls, a set of shorter auxiliary rolls located in the spaces between the primary rolls, and means for supporting said rolls, substantially as described.

3. A sole-leveling roll, having, in combination, a set of primary concave rolls, a set of auxiliary concave rolls shorter than the primary rolls and located in the spaces between the primary rolls formed by the concavities thereof, and means for supporting said rolls, substantially as described.

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

BENJAMIN PHILLIPS.
