chines, of which the following description,

in connection with the accompanying drawings, is a specificatlon, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the manufacture of shoes and is herein shown as embodied in a machine which has been designed particularly for use in shaping turn shoes after the lasting, sewing, shoe turning and relasting operations have been performed. These operations leave the shoe upper and the shoe sole in a more or less distorted and rough conditionv and there is required a large amount of shaping, smoothing and beating out to bring the shoe into conformity with the shape of the last and to impart to both the upper and the sole the smooth and shapely appearance which is demanded in the finished shoe.- This work has heretofore been done very largely by hand tools, although machines have been devised for beating out the sole.

A general object of the present invention is to provide in a single machine the necessary mechanical devices for performing the several shaping operations required on such a shoe and thus to eliminate the need for using the hand tools heretofore employed.

An important feature of this invention consists in a novel combination of means for beating the side of a shoe, such as a turn shoe or a welt shoe, above the projecting edge portion of the sole or the welt, and means for yieldingly supporting the lower face of said projecting portion of the sole or the welt. As shown said supporting means is depressible to permit the introduction of said projecting portion between it and the beating means and preferably it is constructed or arranged to permit the shoe to be tipped or moved angularly so as to receive the beating action in the welt crease close to the sole and then higher up the side of the shoe for thoroughly shaping the side of the shoe as may be required. The heater receives in operation rapid impulses toward the side of the shoe, and with the shoe positioned as above described the ing means a component of downward movement against the top face of the projecting edge of the sole so as to beat as well as to rub this face.

Afurther feature of the invention consists in means for engaging the lower face of the projecting edge portion of a' shoe sole and rubbing it outwardly toward its edge, and means to assist the operator in positioning the shoe for treatment by the rubbing means. Preferably the positioning means comprises a beater arranged for rubbing engagement with the upper face of the projecting edge portion of'the sole or welt while receiving rapid impulses directed inwardly toward the shoe. Preferably also the lower rubbing means comprises a rotary beater which is operative first to beat and then to rubthe sole, and the shoe is positioned by the upper heater to receive the beating action of the lower beater over the upper attaching seam.

A further feature of the invention consists in a beating tool having one portion shaped to engage the side of a shoe in and adjacent to the welt crease, and another portion having a beating face of a different contour arranged to be used alternatively for beating a different part of the shoe.

The several features of the invention will 'bemore fully understood from the following description of the machine in which they are embodied and the invention will then be pointed out in the claims.

Figure 1 is a side elevation of a preferred form of the machine; Fig. 2 shows a modified construction; Fig. 3 is an end view from the left of Fig. 1 illustrating the formation of two of the rotary beating tools; Fig. 4 shows a side elevation, partlyin section, of' a different beating tool; Fig. 5 is a similar view of another beating too1;-F ig. 6 shows a modification; Fig. 7 is a side elevation of one of the upper beating tools arranged in combination with a bottom beating tool; Fig. 8 is a perspective view of the parts shown in Fig. 7.

The machine comprises ahead or frame 2 supported on the post 4: at an elevation which is convenient for the operator in presenting a shoe to the several tools while standing in working relation in front of the machine. The frame has bearings for a main shaft 5 which is driven from a belt 6. This shaft is shown as carrying, in Fig. l, the large rrtary beating tool or beating-out roll 10 and the smaller beating-out roll 12. The larger roll has av peripheral formation which is transversely convex and which comprises a plurality of concentric sole rubbingfaces 14. Between these concentric rubbing portions are beating portions formed by two plane or flat faces 15 meeting in an angle at 16. The effect of this formation on a shoe sole presented against the driven roll is to rub by the surface 14, then strike or impart a blow by the first surface 15, then have a scraping action by the angular face 16 followed by a blow by the second face 15 and then a rub by the next face let. The small beating out roll 12 has a convex periphery formed by alternate concentric portions and flat portions. The peripheral speed of this small roll is of course substantially less than that of the large roll which" latter effects the more se- Vere beating while the former is used for finishing the stock.

In the construction shown in Fig. 2 the shaft .5 carries a drum 20, see also Figs. 7 and 8, around the periphery of which are arranged a series of spindles 22 carrying narrow rings 24 the axial openings through which are of larger diameter than the spindles wherebythe rings are made to extend out by centrifugal force when the drum is driven by the shaft and to yield inwardly as they strike the work. This construction is fullv described and is claimed in my prior'P-atent No. 1,030,837, granted June 25., .1912. For some classes of work this beater gives most desirable results but I have found that in other classes of work, particularly on small shoes and on shoes where the sole is soft or much moistened, the. beating-out action by this roll is more severe than is desirable and better results areobtained by the use of the rolls 10 and 12. In connection with this beater, however, I have herein shown a construction of side beater or upper blocking mechanism which possesses features of novelty and a substantial degree of merit. This mechanism is a further development of the mechanism shown in my prior Patent No. 1,019,878, granted March 12, 1912. In this construction, as herein shown, an auxiliary shaft 25 driven from a belt 23 has a cam 26 for engaging a slide 28 that is supported in a downwardly and forwardly inclined guide 30 whereby said slide normally stands out.

of the path of the cam but may be moved into the path of the cam by the work and may then receive-from the cam impulses of high frequency for acting .on work with light rapid beating blows. A stop 27 held in position by a clamping screw 29 serves to limit adjustably the movement of the slide toward the cam. The heating tool 32- the lower end of the tool and. the rings 24:.

Also in this construction, the slide 28 has erected thereon or formed integral therewith a beating plate 35 the acting face of which is substantially more concave than the concave acting face ofthe beater32 whereby said member 35 may more effectually beat the upper over the top face of the toe. An important characteristic of the operation of this mechanisnnas shown in Figs. 2, 7 and 8, is that the edge portion of the shoe sole is supported-on its upper face against the lower end face of the beater 32 while the lower face beaten, or more strictly speaking, is being rubbed toward its edge by means of the rolls 24. The arrangement is such that the shoe will normally be so held tangentially to the of the sole is beingperiphery of the ring beater that the rings will strike the shoe bottom. at some distance backwardly from the vedge of the sole and preferably substantially over the seam by which the sole and upper have been con nected. By this means a local beating of the shoe bottom over the seam vis effected for flattening the seam against the bottom face of the last. The side beater 32 serves as the guide for the shoe to cause action to take place at this distance from the edge of the shoe. After the ringsstrike the shoe they glide along the-surface until they pass from under the shoe sole at its edge. .This the shoe so-lea rubbingand smoothingaction while the upper face of the sole margin is supported against the beater 32. Co-

incident with this rubbing of the sole marthe beating,

gives to the marginal portion of gin the vibration of the beater 32 effects lower end face of the beater .for receivingv the smoothing action which follows from the. reciprocatory movement of said, heater.

upper is similar in its nature to the yielding support furnished by the rings of the ring beater 20. The reciprocating beater 32 is shown in these figures as extended upwardly above the slide 28 and provided with a second beating face 35 corresponding with the beating face of the member 35 shown in Figs. 2, 7 and 8. In this construction the beater 32 is adjustably held on the slide 28 by a clamping screw: indicated at 31. In Fig. 6 the table 10 is formed as a plate that is hinged at its rear edge and yieldingly uppressed by a plunger 41 so that the table follows the shoeas the heel end of the shoe is tipped upwardly for extending the action of the beater 32 higher up along the upper from the plane of the sole. It is also to be noted that in the construction shown in Fig. 6 the plane of the lower end face of the beater 32 and likewise the plane of the table and the shoe sole is at a substantial angle to the plane in which the slide 28 reciprocates so that said beater 32 has in effect a downward, as well as forward, component. of movement toward the shoe and so eflects a slight downward beating upon the upper face of the margin of the sole.

The shaft 5 supports a cam 45, Figs. 1 and 1, and the frame has a bearing stud 46 from which is pivotally suspended an arm #18 that has on its lower end a vertically concaved beater 50 the heel of which may, by pressure of said shoe against the beater, be forced into contact with the cam 45. The arm 18 is normally held. yieldingly away from the cam 45 by an adjustable eccentric 52 carried by the frame and a springpressedplunger 54 carried by the arm 18. The beater 50 is shaped at its lower portion to extend deeply into the crease between the upper and the sole for beating out and smoothing any wrinkled or uneven portion of the upper not readily. reached by the other beating tools.

In Figs. 1 and 2 are shown also portions of a novel heating mechanism which is disclosed in detail and claimed in my prior U. S. Patent No. 1,048,637, granted Dec. 31, 1912.
