, 17 Claims.

This invention relates'to machines for use in shaping thesoles of boots and shoes, particularly those in which the shaping is done by impact.

Most fine. shoes, and. particularly those intended to be worn by women, are required to be made with close shanks; that is, the angular space between the upper and'outsole, or welt if the shoe is a welt shoe, commonly referred to as thewelt crease, must be closed up so that the upper and outsole, or welt, as the case may be, are substantially in contact. During the operation of sewing on the outsole of a welt shoe the welt crease must be open to permit the operation of the, sewing instrumentalities in securing the welt and outsoletogther. The operation of closing the shank is usually performed by hand, a hammer being-used to beat or peen the margin of the outsole or edge face of the outsole and cause it to be so shaped and bent that the welt crease is permanently closed.

In case the outsole is channeled to receive the stitches of the outsole sewing machine, it is difficult to direct the blows by hand with such accuracy as to avoid hitting the channel leaf and breaking or otherwise injuring it, .and in Work that-is stitched aloft, that is, where the stitches are located on the surface of the out sole, hand work leaves much' to be desired in the facilityand accuracy with which the operation is performed. I

Objects of the present inventionare to provide mechanical means by which the desired operations may be performed with ease, quickness and precision. I I d Features of the invention consist in an organization comprising beating means, such as a rotary beater, to which the shoe may be presented while held in the operators'hands, with channel engaging means for guiding the shoe with relation to the beating means as theshoe I v 'portlon of the arm 18 is angularly disposed with is moved longitudinally to present different portions of its margin to the beating means. The guiding means preferably serves also toguard and protect the channel leaf from contact with the beating means. 1 The means for guiding the shoe and guarding the-leaf is preferably aranged for yielding movement to permit movement" of the shoe into engagement with the beater and is preferably rotary to cause as little impedance as possibleto longitudinal movement of the shoe, ,As shown, the guiding and guarding means consists of a roll housed within the end of the beating'mea'n's andhaving its periphery contoured to correspond roughly to. the

shape of the inturned channel leaf which'it is to engage. V

An edge gage for determining the lateral position of the work is provided, which gage may, as illustrated-comprise a roll arranged formtation upon an axis substantially perpendicular to thatof the rotary beater. The lbeater is preferably provided on its periphery with three beating portions, the periphery of the beater being cutaway or rentrant between said portions.

In the drawing, I i V Fig. 1 is a side view of the machine embodying the present invention; v

Fig. 2 is a side view of thefoperating instrumentalities in working position with respect" to a shoe shown in section; I

Fig. 3 is a view similar to Fig. 2 showing the machine arranged to treat a shoe that is stitched aloft, the shoe being shown in section; and

Fig. 4is an end view of the pounding 'tool.

As shown in Fig. 1 'of the drawing, arotary beating tool 2 is mounted'on a shaft l to be continuously driven at high speed. Conveniently, the shaft 4 may be the armatureshaft of an electric motor6v designed'to run at the proper velocity, though, of course, any other suitable means forfrotatingthe shaft may be employed.

To support the work guiding means with which the machine 'is provided, a' stationary sleeve 8 is arranged outside the shaft 4 and may, for example, be fixed to or integral with the casing of the motor 6. On the sleeve 8 a support 10 is fitted to slide or turn, a portionpf the support being slit at 12 and provided with a clamp screw 14 bywhich thememberflO may be clamped in fixed position on the sleeve 8. Pivoted at 16 to the upper portion of the 'supportlq isanarm 18 the outer. portion. of which is bent, downwardly in front of the beating element2. The lower respect to theshaft 4, and upon the" angular portion is pivoted forrotatio'nby a screw.19 a

ranged to enter-the channel, and' th'e concaved portion of the roll to engage the folded back channel leaf and keep. "it out of contact with the beating tool- 2 Inorder that a roll of suitable size may be' use d and the lip of preferably projects slightly below the beater 2,

being determined by a screw 24 threaded through the arm and engaging the support-i=0. To hold the arm and roll so that they may yield upwardly in response to pressure of the shoe upon the roll, a stem 26 is secured to the support 10 and passes upwardly through a hole in the arm 18, a spring 28' being arranged on the stem 26 Joetween the arm 18 and a spring tension adjusting thumb nut 29.

.- Uponthe lower .side of the support 10 is a holder 30 having a vertical slot through which passes a cap screw 32 threaded into the support. The lower surface .of the holder '30 is channeled to receive a curved member or arm 34 (Fig. 3), upon the outer .end' of which a roll 36 is mounted by a screw 38 to rotate on .a vertical axis. The inner end of the manber 34 is slotted to receive a cap screw 40 by which it is held in adjusted position to the holder 3.0.

It will be observed that the curved arm .34 is made very thin heightwise .along its central portion so that itsouter end can yield vertically in case the shoe is tipped far enough to cause the upper of the .shoe to engage the roll 36.

The roll, therefore, will not interfere with upward pressure of the shoe against the pounding tool, even when tipped to an extreme angular position with respect to the tool.

In the use of the machine, the motor is started to cause the beating tool 2 to be rotated. If a welt shoe having a channel for the outsole seam is to be treated, it is presented as indicatedin Fig. 2, the lip 22 of the roll being positioned in the channeland the folded back channel leaf being located in the concave portion of the periphery of the roll. The shoe is then raised to cause the tool 2 to engage and beat down the margin of the shoe, the shoe being suitably tipped on its longitudinal axis, either initiallyor progressively, to cause the angle or opening be.- tween the upper and welt to be closed. The shoe is also, of course, moved longitudinally to cause not only the entire shank portion but also, if desired, other portions of the sole margin to be similarly treated. The roll serves to guide the shoe as it moved lengthwise of the margin, so that the action of the beater is properly localized on the margin of the sole and protects the lip from injury by accidental contact with the beater. When. a shoe that .is stitched aloft is to be treated. the machine is adjusted as indicated in Fig. 3, the shoe being located laterally with respect to the tool by the roll .36 which, being mounted on an axis substantially perpendicular to the sole, offers little resistance to movement of the shoe longitudinally. By holding the edge of the .sole against the roll 36, the action of the beating tool 2 is properly localized on the margin of the sole, and, bytipping the shoe as before, the margin of the sole is bent and beaten down to .cause the crease between the upper and sole or welt to be closed. In some work it is desirable to employ both the roll 20 and the roll 36 at the same time, the roll 20 then serving to protect the channel leaf while the roll 36 guides the shoe to cause the action of the beater 2 to be properly localized.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
