MACHINE FOR OPERATING ON SOLES.

Specification of Letters Patent. Patented Jan, 29, 1918 Application filed April 22, 1916. Serial No. 92,855.

To all whom it may concern.

Be it known that I, EDWARD EnrcKsoN, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Operating on Soles; and I do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to machlnes for operating upon soles, and more particularly to machines of this type employed for shaping a flat sole before it is incorporated in a boot or shoe.

It is desirable that the sole of a turned shoe shall be shaped to approximate the contour of the last bottom prior to the in corporation of the sole in the shoe. By shaping the sole in this manner the operation of sewing the upper to the sole is facilitated as the margins of the sole are located in close proximity to the bottom of the last, owing to the curvature wh ch has been imparted to the sole. both transversely and in alengthwise direction. by the molding operation.

The object of the present invention is to provide a machine of simple construction which is conveniently operated to shape a flat sole into conformity with the curvature of the last bottom.

With this object in view the several features of the invention consist in certain novel features of construction, combination and arrangement of parts hereinafter described and claimed. the advantages of which will be obv ous to those skilled in the art from the following description.

The accompanying drawing shows a side elevation of the machine for pounding soles.

In the present invention the sole is convenientlv shaped by a stationary sole sup port provided with a fiat face having a curved recess formed therein and cooperating with a hammer reciprocating in a direction normal to the face of the sole support and having a rounded face conforming generally to the curvature of the recess to causethe sole to be molded between the hammer and sole support. It will be obvious to those skilled in the art that if the sole is held in a stationary position on the support, the

hammer will operate to form a cup-shaped depression in the sole, and if the sole is moved across the support during the opera tion of the hammer the latter will curve the sole both transversely and in a lengthwise direction In the usual operation of the machine, the sole is fed in a lengthwise direction across the work support during the continuous reciprocation of the hammer. This mode o operation causes the sole to be compacted and curves the sole both transversely and in a lengthwise direction to cause-the sole to approximate the curvature of the last bottom.

In the illustrated embodiment of the invent1on, the machine is provided with a sole support 1 and a cooperating hammer 2 movable in. a direction normal to the face of the sole support. The sole support is provided with a curved recess or depression 4 in the face, as shown clearly in the drawings, and the working face of the hammer is curved substantially in accordance with the curvature of the recess to cause a fiat sole to be engaged between the hammer and sole support and shaped in the manner shown. The sole support is conveniently mounted upon a laterally extending arm 5 which is secured to the side of the machine frame 6 through bolts 7. The hammer 2 is secured to the lower end of a stem 9 which is slidingly mounted for vertical movement in upper and lower bearings 11 and 12 respectively, formed upon a head 13. The hammer is conveniently reciprocated during the operation of the machine from an actuating shaft 15 journaled in the head 13 and provided with a driving crank 16 connected to the stem 9 through a link 18 and collar 19 having a stud '20 projecting laterally there-- from and connected to one end of the link 18. In order to guide the collar and prevent turning upon the stem 9, the end of the stud 20, as shown clearly in the drawings, engages with a vertical guidcway formed in a laterally projecting portion 22 of the head 13. In order to cause the hammer to deliver a yielding blow upon the sole andto prevent breakage of the machine through an undue stress. the collar 19 is con.- nected to the stem 9 for downward movement through a coil spring 25 surrounding the stem and interposed between the collar and a nut 26 threadedly mounted upon the stem.

The stem is positively moved in an upward direction through engagement of the collar with a stop nut 27 threadedly mounted upon the stem above the collar. Both of the stop nuts 26 and 27 are provided respectively with locking nuts 28 and 29 to maintain the stop nuts in their adjusted positions. With this construction, the upper and lower limits of movement of the stem may be determined by adjusting the nuts 26 and 27 and in addition the force of the blow imparted to the solo by the hammer 2 may be varied as desired. I

While it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this construction and arrangement is not essential, except so far as specified in the claims, and may be changed or modified without departing from the broader features of the invention. 7

T he invention having been thus described, what is claimed is:

l. A machine for shaping flat soles having in combination, a stationary sole support across which the sole is fed and having a curved recess formed therein, a hammer having a rounded face coiiperating with the recess in the sole support to shape a sole, means for supporting the hammer for movement in adirection normal to the plane of the feed of the sole, and mechanism for reciprocating the hammer to impart a series nssasea of blows 'to the sole and curve the sole both longitudinally and transversely as the sole is fed under the hammer.

2. A machine for shaping fiat soles, having in combination, a stationary sole support across which the sole is fed and hav ing a curved depression formed therein, a hammer having a rounded face cooperating with the depression in the sole support, means for supporting the hammer for movement in a direction normal to the plane of feed of the sole, and yielding connections for reciprocating the hammer to impart a series of yielding blows to the sole and cause the sole to be shaped both longitudinally and transversely as the latter is fed under the hammer.

3. A machine for operating upon soles, having, in combination, a stationary sole support provided with a flat face in which a curved depression is formed and across which the sole is fed, a stem slidingly supported for vertical movement in the machine frame above the sole support, a hammer having a rounded face and secured to the lower end of the stem, an actuating shaft, a collar yieldingly connected with the stem, a driving crank connected to the actuating shaft, and connections between the collar and driving crank for reciprocating the hammer.
