SHOE-BEATING MACHINE Speciflcatlonof Letters Patent.

like reference characters on the drawings indicating like parts in the several figures. This invention relates to machines for heating or shapingl shoes, and particularly .to a machine of t e type in which rotary beaters are employed for working the upper fmaterials over a last bottom, and for shaping, compacting and smoothingthe bottom of a lastedshoe to prepare it for the laying of the outsole.

An object vof ,the invention is .to provide an improved machine in which the beating members" have their'working facesin poi-ii tion to work the upper materials inwardly from thetwo-sides of a last bottom at the same time.

.A- characteristic of the machine, is the provisionof apair of beating members with their ad'acent rubbing faces set edge to edge and inclined toward one another. By this arrangement an especially eflicient treatment is given to the shoe stock near the edge of the shoe bottom. Moreover the location of the working surfaces adjacent to one another provides for treating both sides'of a shoe at once, and one of the rubbing members servesto brace a shoe against lateral displacement by the action of the other member.

In accordance with the preferred embodiment of my invention herein shown and described, I provide a air of rotary disks aving rigid, ribbed meat .about relatively stationary axes, which are preferably inclined toward one another to nt in'the same plane that portion of their working surface which is intermediate hetweenthe axes of the two disks. The rubbing faces of these disks are preferably It should be understood 7 however that convex is here used in its broad sense to mean that the working surface of the slopes away oris inclined obliquely from the center to the periphery.

It is equally within the contemplatlon of my invention that the end face of the disk be beveled from the center outwardly to the periphery in the form of a truncated cone,

for example, or that the line of convexity of the end face be curved or an arc of a circle. In accordance with a 'very important further feature of my invention the end faces or working surfaces of these disks are preferably formed with reversely inclined spiral ribs which extend outwardly from adjacent to the center a number of turns around their axes substantially to the periphey. This disposition of the disks edge to edge 1'01 rotation about relatively fixed and inclined axes together within the spiral formation of the convex rubbing ribs operates to work the upper materials inwardly from the side of a last bottom with a screwing movement. The pressure of the tool upon the work is localized at any given time upon a comparatively small high pressure area. Moreover the high pressure areas are constantly shifting or traveling inwardly from the side of the last bottom toward the center, and in consequence the shoe stock is wormed inwardly, for, as the loci of high pressure are constantly shifting, some part of the tool is always contactlngwith the work to drag it toward the center and away from the edge of the shoe. Furthermore, the spiral formation on the end faces of the disks is so arranged as to effect intermittent depressions of a shoe having a rounded bot-- tom as the outer ends ofthe ribs pass over it. Accordingly, means may convenientl be provided for raising the shoe after eac such depression thereby initiating with impact the engagement of the shoe with a new portion of the ribs.

These and other features of the invention of an'illustrative embodiment thereof read in connection with theaccom anying drawings, and will be definitely pointed out in the appended claims.

Referring to the drawings: Figure 1 isjan elevation of the machine. Fig. 2 is a plan view of the disks. Fig. 3 is a section on the line 22 of Fig. 2.

The machine comprises a suitable frame in which is arranged a bearing 2 for supporting a shaft 4. The shaft 4 which is driven by'a pulley 3 is provided with a beveled' gear connection with a shaft 6 for driving the shaft 6. The two shafts 4 and 6 the periphery of the end face. These

spirals

12 and 14 are oppositely wound or reversely inclined with relation to each other, (Fig. 2). The convolutions of the spirals 12 and '14 are separated each from the other by a very substantial space, as clearly shown in Fig. 2. This formation of the convex rubbing ribs in substantially spaced spiral convolutions operates to effect intermittent depressions of the rounded bottom shoe operated on, as the outer ends 24, 26 (Fig. 2) of the ribs 12, l l pass over it. This results in a bumping movement of the shoe as it engages a new part of the rib. To raise the shoeto contact with the ribs after eachsuch depression any suitable means may be employed, such for example, as is illustrated in Fig. 1 in which the shoe is shown with its last connected to a spindle 18 in a shoe supporting-jack 20; the ack being shown as yieldably supported by a spring 22 which normally tends to raise the shoe in elevated position and which therefore, whenever in the rotation of the heaters, the

outer ends

24, 26 of the

ribs

12, 14 pass over the shoe,

operates to immediately elevate the shoe intO operative engagement withnew parts of the ribs, accomplishing this positioning of the shoe without any violent bumping or rebounding.

It ,will be noticed that the working surfaces of the disks are edge to edge or adjacent to one another (Fig. 2). Moreover, the

axes of the disks 8 andlO, namely, the shafts 4 and 6 are, as shown in Fig. 1, preferably inclined one toward'the other and are .stationary relatively to each other. Preferably, the inclination of theshafts 4 and 6 is such as to present in the same plane that portion of the working surface of each disk that is for the time being intermediate between the axes of the disks as plainly shown in Fig. 1. This disposition of the disks together with the spiral formation of the convex ribs, (Figs. 2 and 3) before described, adapts the disks for engaging simultaneously the two opposite sides of the shoe bottom with a peculiar screw-like movement whereby the stock is at the same time worked inwardly from the two sides, and each tool is made to exert a maximum pressure at first'on the edge of the shoe bottom n and then in succession on points successively nearer the center producing in efi'ect,

small high pressure areas, as for example at 28 (Fig. 3) continually shifting inwardly. As a result, without injury to the stock, the stock is more thoroughly, evenly, and smoothly worked toward the center and away from the edges. 7

' In operation, the shoe is successively treated at the heel seat and then if desired, along the shank, forepart and toe portions, the operator either holding the shoe up to the machine, and shifting it longitudinally thereof by hand or, if a construction such as is shown in Fig. 1 be employed, the supporting jack 20 may be arranged to slide back and forth lengthwise of the shoe.

1. A shoe shaping machine, having, in combination, two rotary disks, arranged edge to edge, and provided on their ends With reversely inclined spiral ribs extending one or more times around their axes.
