AUGUST R. SCHOENKY, OF SOMERVILLE, MASSACHUSETTS, ASSIGNOR TO REECE SHOE MACHINERY COMPANY, OF BOSTON", MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.

WELT-Beaune MACHINE.

Application filed July l5, 1919.

To aZZwiom it may concern:

Be it known that I, AUGUST R. Sononivnr, a citizen of the United States, residing at Somerville, in thecounty of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in lfVelt- Beating Machines, of which the following is a' specification, reference being had therein to the accompanying drawing.

This invention is a novel welt beating machine, by which I refer to a machine for beatii'ig or analogously reshaping the shoe welt strip attached to a shoe for the purpose of flattening it out' preparatory to suc-l ceeding operations, such as the attachment of the outsole. Y

Heretofore known welt beatingmachines have proved very inefficient in the 'proper reshaping ofthe welt strip on the more difiicult shapes of shoes, and the main object of the present invention vis to overcome the difficulties heretofore encountered, and to afford a machine in which the welt may be expeditiously, efficiently, and non-injuriously attened particular objects and advantages of the present improvement will appear in the hereinafter following description of one form or embodiment of the invention, or will be apparent to those skilled in the art. To the attainment of the objectsland advantages referred to, the present invention consists in the novel'machine, mechanisms, devices, combinations and arrangements herein illustrated, and described.

In the accompanying drawings, lFigure 1 is a side elevation, partly in central section, of a welt beating machine embodying the present invention.

Fig."`2 is a t'opfplan view of the same. Fig. 3 is a right elevation of the hammer or 'beating tool.

vil block 12, having its operative or niachined surface 1:3 preferably horizontal. A slight recess 1a is Vshown at the inoperative side of theanvil for a purpose which will bove the anvil is the beater or hammer 16, which has the usual down and up inove- The unat one side, and prefments toward and from the anvil. der surface of this tool erably radially arranged, has an elevation,

rib or ridge 17, adapted at certain times, as

will be explained, to partake of the welt re-`r shaping or flattening action. y "lheup and down movements of the beating tooll are effected by' a vibrating arm 18, fiilcruined at 19, and having at its free end a head 20, carrying the beating tool. For convenience, the upper portion 2l of the head and arm may beremovable, giving access to the interior parts for assembling, cleaning, etc.

The operating shaft 22 is shown as provided. with the usual fast and loose belt pulleys, and at a point beneath the arm 18 carries an eccentric 23. The eccentricy strap 2l has its web or shanlr extending upwardly vibrating arm 18. By this the arm, and therefore the beating tool, are given arapid up and `down vibration of small am blitude, so as to deliver repeated blows flatwise upon the outstanding' F l.

lhe tending up through the head to an exterior point, where a pair of lock nuts 2'? are applied to it to limit or determine the normal position of the tool in the head. Ay leather washer 28 is placed .beneath the lock` nuts to minimize wear andshoci. Itis desired the tool 16 and but not the momentum .of the head ory arm of the machine, andconsequently the `tool and shank are rendered vertically slidable in the head, being held normally in the relative position shown byv a yields, thusy limiting the beating force, as stated, to that provided bythe momentum or energy of thetool l16 andlits shank 26., IV ith the yield of the spring there will be a slight separation between .the lock nuts 27 and the head 20, the washer 28 taking up the shock on restoration of position.

beater tool 16 hasits shank 26 eX-k spring 29,l which4 ioc - l edge, than at the other or inner edge.

Vbetween -the anvil and the hammer, and

be incapable of satisfactovvelt, especially around the sharper'turns of a pointed shoe. Broadly, the present invention operates so as to swage or spread the material of the Welt to a greater degree at one edge, namely, the outer This in different Ways, for of the anvil differential this is found to rily flattening the might be performedA example,by a slight inclining or hammer, but 1 prefer a spreading action which may will and set aside at Will, so that the easier parts of the Work may be performedin the usual manner by a simple, flat hammering action;

To this end 1 apply or form on one-or the other of the tivo members,V preferably the hammer'member, a slight elevation, projection being positioned, so as to give an accentuated or increased` sivaging' or lspreading action along the outer edge of the Welt. This may take the form of a radially arranged-rib or elevation 17, tapered or graduated in degree or height, as Vindicated in Figs. 1, 3, l and 7. Fig.` 7 shows the rib 17 in operative relation to the shoe and Welt, and it Will there be seen that the thicker or higher portion of the rib is applied to the outer edge or periphery of the Welt. By this arrangement during the spreading` or beating action, the periphery of the material is squeezed and swag-ed or spread to a greater degree than the inner part of the Welt, thus materially lengthening the periphery and giving the differential spreading action before men- Y tioned, 'so as to satisfactorily enable the Welt to be properly flattened Without resorting to the slashing or slitting, which has sometimes been adopted heretofore to a similar purpose.

VOrdinarilythe differential spreading action may not be' required, and I have rendered the beating tool 16 circularly adjustable, so that at will the tapered rib 17 may be brought to the inoperative position shown it may be accommodated within the recess 14 of the anvil, when not in action, or the operative position shown in Fig. 7. h n

n order to rotarily adjust the beater 16, a bevel gear 30 is fitted to a squared portion of Vthe shank 26. This vfreely permits .thel yielding movement mentioned, While the gear is able to rotate the tool between its different operative positions. `The bevel gear 30 isengaged by the bevel gear 31, mounted at the upper end of a shaft 32, mounted Within the machine arm 18. n'the presentembodiment `I Apropose only two ad] be employed vat,

1 prefer to employ a spring 35, normally holding the shaft 32 and the beater tool in the position shown in in its lower end is held in the shaft 32,.a'nd

its upper end engages in a socketV piece 36,l

surrounding. the shaft 32 and having peripheral teeth Si?, as shown in Fig. 6, engaged by a Worin 38, exteriorly Vaccessible for rotating the stop piece and tightening the 'spring to any desired degree. The shaft 32 at its lower end has abevel gear 39, engaging a bevel gear 40, mounted loosely on the aXle or stud 19 on which the arm is fulcrumed. ecured around the hub of the vbevel Ygear 4Q is a pedal chain 41, presumed to be connected to a convenient pedal.

The operator holds the inverted shoe, as

shown in Fig. 1, and guides it advancingly While the welt travels between the hammer and anvil, and is beaten into fiat condition by a rapid succession of repeated blo'vvs.V

When the operator comes of the shoe, Where the quired to be spread more than in ordinary to depress Vthe pedal chain 41, thus giving a half turn tothe hammer, Without stopping machine, and bringingy the differential spreading means into operative position, as in Fig.' 7'. During to a difficult part fied Without departing from the underlying principles, no limitation to'such features is intended eXceptas setrforth in the appended claims.

What is claimed is: Y 1. A welt beating machine comprising an anvil, a beater vibratable vibratable arm carrying as in Fig. 1, Whereas, when. the beater is rotated so that thepin Fig. 1. This spring Welt periphery is rethat I khave thus dethe operationk of' the l Y the continued action, `While thepedal is down, the Welt periphery above the anvil, av 4 the beater at its f free or head end, said beater having beating surfaces oi different character, and Conner;- tions comprising a longitudinal shaft mounted on the arm for transmitting rotation to adjust the rotary position of the beater.

2. A, Welt beating machine comprising an anvil, a beater vibratable above the anvil, a vibratable arm carrying the beater at its free or head end, said beater having beating surfaces of diiterent character, and having its shank mounted both slidably and rotatably in the carrier head, a shaft extending longitudinally of said arm and bevel-geared to said shank to rotate it, and connections at the pivot of said arm for rotating said shaft.

3. A Welt beating machine comprising an anvil, a beater vibratable above the anvil, a vibratable arm carrying the beater, means for vibrating the arm, and means for ad-V justably rotating said beater, the beater having` a circular flat face interrupted by a single tapered rib extending from its center' to periphery.

In testimony whereof, I have aiixed my signature hereto.
