UNITED STATES PATENT OFFICE.

FERDINAND MEINEOKE, OF MILWVAUKEE, VISCONSIN.

WOODEN-SHOE MACHINE.

SPECIFICATION forming part of Letters Patent No. 310,216, dated January 6, 1885.

Application filed June 30, 1884. (No model.)

To all iuhom it may concern.-

Be it known that I, FERDINAND MEINEOKE, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Device for Excavating Vooden Shoes;

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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a machine for excavating wooden shoes.

The construction of my machine is explained by reference to the accompanying drawings.

Figure 1 represents a perspective view. Fig. 2 represents the cutting-wheel removed from the machine. Fig. 3 is a horizontal section of the cutting-tool.

Similar parts are referred to by the same reference-letters.

A A are two vertically-arranged posts of a frame to which my machine is rigidly attached. The frame is made rigid to the building or otherwise held in place in a vertical position, as shown.

13 represents a shoe-block in position to be excavated.

O is a pattern or form by which the movements of the shoe-block B are governed in relation to the cutting-tool. Both the block and form are retained in place and simultaneously moved by the holders A A, consisting of arms C G and plates D D.

The shoe-block and form are rigidly secured in the holders by the stationary dogs E at their lower ends, and at their upper ends by the point of the screws F, which dogs and screws are, by being turned forward, forced into the shoeblock and form a sufficient depth to permanently retain the shoes while being operated upon. The holders are each supported both front and rear upon the pins G, which pins permit them to be inclined toward the right and left, as required, to bring the cutting-toolH from one side of the shoe to the other. The plate I, to which said plates E are attached by pins G, is also provided with pivotal supports J J, which supports are arranged at right angles to the axis of the pivots G G, and permit of the forward and rearward inclination of the holders.

It is obvious that I am enabled by the several pivotal supports to move the holders in any direction, either forward, rearward, or in a circular course at will, whereby the cutting-tool is brought upon all sides of the interior of the shoe, while by the upward and downward movement of the cutting-tool I am enabled to bring it into the toe and upper part of the shoe, and thus by the combined move ments of the shoe and cutting-tool make the excavation of the shoe complete and perfect.

The arms 0 (J of the holders are connected together by the bar K, which is pivoted to the edges of said arms by pins L L, whereby any movement given to said bar K is communicated alike to both of said holders, and they are simultaneously moved in all directions, as mentioned, while they at all times maintain the same relative position to each other.

To one end of the barKis attached a lever, M, by pivotal bolt N and link or joint 0, by which said holdersare operated. The link 0 turns freely on the end of the bar K, permit ting of the upward and downward movement of the end of the lever M, while the pinNpermits of its horizontal movement. The upper end of the lever M is supported upon the arm P, with which it is connected by the link or swivel Q, consisting of sleeve to, for the reception of arm 1, and sleeve I), for the reception of the end of the lever M. The sleeves a and b are connected together by a pivotal bolt,

which permits them to turn, whereby the free end of the lever M may be swung horizontally toward the right and left, while as abackward and forward movement is given to the hold ing device said lever M slides through the sleeve Z), and as the free end of the lever M is raised or lowered thesleeve a is free to turn on the arm P, whereby it is obvious that all the connecting devices of said lever M, with holders and frame, are such as permit of its free movement in all directions required to properly excavate the shoes.

As both holders A A are supported and connected so as to move together, always maintaining the same relativeposition to each other, it is obvious that the shoe in course of construction will move precisely as the form moves, and the interior of the shoe-block B is made the exact duplicate of the form.

Vithin the form C is a guidebearing shaft It, having an upward and downward movement, which is controlled by the lever S, while the horizontal or swinging movement of the form is controlled entirely by the bearing end of the rod R against the inner walls of the form C. The rocking plate I is connected with and supported by the standards A A upon the bracket T. The bracket T serves as a guide and bearing for the shafts U and B, while the lower ends of said shafts are supported upon the vertically moving slide V. The slide \V is held in place by the guideways Y Y, upon which it is adapted to move freely upward and downward as the lever Sis raised and lowered, said lever and slide being connected together by the link B. The guideways Y Y are connected with the standards A A by the arms D D D D. The rear end of the lever S is supported by the rod or shaft H, which passes through a hole provided therefor in the end of said lever, thus acting as its fulcrum, the respective ends of said rod H bein g permanently affixed to the standards A A, as shown. The shaft R is rigidly fixed to the slide \V, and simply moves up ward and downward with it, while the shaft U is adapted to be rapidly revolved in its hearing by the belt E acting on the long pulley F. The length of the pulley F is such as to permit of the required vertical movement of the shafts U and It without causing the band to run off from the pulley. The cutter H is of spoon shape. The cutting-edge is slightly more eecentric than its opposite edge, so that as it-is pressed into the wood it will cut a thin spiral shaving from the point or center outward to its periphery.

Preparatory to excavating shoes by my ma chine they are first turned upon the outside into the desired shape, when they are placed beneath a similar cutting or boring knife, and the rear part of the shoe above the heel, and instep excavated. This being done the shoe is placed, as at B, upon the dog E, and the hand-screw F is turned down upon the toe of the shoe until by the pressure thus applied the dog E and point of the screw F are driven into the shoe-block sufficiently to hold it rigidly while being excavated. This being done and the cutting-tool set in motion the operator grasps bot-h of the levers M and S, and moves them, as mentioned, so as to bring the upper end of the former H to all parts of the interior of the form 0, when it is obvious that as the relative movements of the cuttingknife and shoe-block B are the same as said form 0 and the guide-rod B said shoe-block will be excavated in precisely the same shape as the form.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for excavating shoes, the combination of the bracket T, rigidly affixed to a supporting-frame, oscillating plate I, pro vided with pivotal supports J J, operating in journal-bearings 011 said bracket, oscillating holders A A, respectively secured to said plate I by pivotal supports G, said holders being connected by a bar, and provided with an operating-lever, by which they are simul taneously moved together, shaft 'U, provided with cutting-knife H, shaft It, provided with bearing end operating against the interior surface. of the form, form or pattern 0, rig idly fixed to the holder, as shown, slide XV, guidewa-y Y Y, said slide serving to support and simultaneously move said shafts U and B, link B, and lever S, all substantially as and for the purpose specified.

2. In a machine for excavating wooden shoes, the combination of the oscillating holders A A, mounted upon pivotal. supports which permit of their universal movement, connecting-bar K, sleeve or link 0, adapted to turn on said bar K, pivot N, handle M, secured to said sleeve 0 by said pivot, universaljoint or swivel Q, arm P, and post or frame A. substantially as set forth.

o. In a machine for excavating wooden shoes, the combination, with the oscillating holders A A,ot the movable retaining-screws F F and stationary dogs E E, said screws being adapted to retain the upper end of said shoe-block and form,while said dogs retain their lower ends, as set. forth.

4. In a machine for excavating wooden shoes, the combination, with the single slide \V and handle S, connected together by link B, said slide being mounted on the guideways Y Y, of the vertically-moving rotating shaft U, provided at its upper end with a cutting-knife, and the vertically-moving shaft B, provided at its upper end with a former, substantially as set forth.

In testimony whereofI affix my signature in presence of two witnesses.

FERDINAND MEINEOKE.
