Specification of Letters Patent.

Patented Feb. 3, 1914.

Application filed ma 5'; 1910. Ser'ialNo. 559,479.

To all whom it may concern Be it known that I, CHARLES DE Minion, a citizen of the United States, residing at Portsmouth, State of Ohio,-have invented certain Improvements in ShoeShaping Machines, of which the following description, in onne tion with the acco pan-yingdrawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes and particularly to improvements in shoe shapin apparatus.

in the r'rranufacture of shoes the upper materials are stretched over the last as a form and the marginal portions laid down upon the inner-scleand secured thereto after which the eutersole is applied to the shoe bottom. The upper stretching and overlaying: mechanisms are constructed and arranged primarily for performing'the functions suggested by their names and it. is usually necessary to do additional shaping of the shoe on the bottom and side faces adjacent to its edge for formin suitable seat for the outersole tobe laid upon and for giving to the sides otthe finished shoe the trim appearance and well definedconformation to the contourof the last which is desirable. It hasbeen customary to perform these lastnamcd functions beating the shoe with a hand hammer although mechanical boaters have been devised and are now quite extensively used, some of which beat the bottom of the "shoe or pound up the shoe as it is called in the shoe shops while others both pound up the shoe. and beat or block the sides of the shoe, and yet others are side Whether these operations are performed byha'n'd or by a'machine de signed for the purpose they have constituted separate operations in the manufacture of a shoe and required one or more additional handlings of the shoe. In the development of shoe making in recent years perfection has beensought by dividing processes and adapting machines and methods and training operators to do one step in the best and most expeditious way. In this manner excellence of the lasting: and the pfmnding up and blockmg operations.-

in the .county of Scioto and product has been obtained from.

It is an object of this invention to combine in one machine the Several instru'mentahties required for the shoe shaping operations, thus prodncingr'a combined machine including lasting means and pounding up, or blocking, or both pounding u and blocking means, in the use of which a single handling of the shoe will be required and the subordinate operations will be erformed Without increasing materially, i all, the time usually required for the lasting operations alone. I J

The lnvei'iti'on is sho'ivn, by way of extanple, as embodied in a special form of lasting machine of the hand method type shown in United States Letters Patent No. 584,744. In order to ebta'in'the above stated object in a relatively complicated and highl organ ized machine like this 21 Why careful coordination of the sever-a1 instrumenta'l'itjes is required to obtain a c'ofiibintl actitiii which will possess the effectiveness of the separate operations.

A very important featiire of this iriifention consists in the combination With means for working a portion of an upper over a last, including means for rubbin the upper hard down upon the last. bottom, of means for beating the up er.

It is also new by this invention to provide means to rub an upper over a. last, then uncover the upper to allow it to react and then to beat the upper to flatten it'down upon the last bottom for orming a seat for the outer sole. i

vA new feature of this invention is found in the combinat-ioii with the upper 'overworking means, and means for tacking or otherwise fastening the upper, of means for subsequently beating the overworked and fastened portion of upper to flat-ten it down for a seat for the outersole, as Well as in the combination of automatic devices operating successivelyin the same cycle of the machine to tack the upper and after the tack has been driven to beat the )orti'on of the upper that has been tacked. t is Well understood that after a portion of upper has been over- WOlkQClilllCl a tack driven to secure it and'the overworking means has been withdrawn the upper rises and pulls back or reacts more or less in adjusting itself to its new position and to the lines ofstrain maintained by the tack.- By allowing this reaction to occur first the beating operation flattens the upper down in the position which it will eventually occupy and forms a smoother seat for the outersole than would be obtained by beatingthe upper before the reaction takes place.

As herein shown the overworking means is embodied in a horizontally reciprocating wiper, through which operates the tack driver, and the beater is a substantially vertically reciprocating pounder which rises from the work and remains above the wi er while the latter rubs the upper inwar ly from the edge of the shoe bottom and holds it while the tack is being inserted. Then,

after the wiper has been retracted to uncover the upper the pounder is driven downwardly against the shoe bottom upon the portion 0 upper which has just been overworked. y 0 y It is also a new feature of this invention to' provide means to insert a tack and means for thereafter pounding the stock which has been securedby the tack, as distinguished from driving a tack and simultaneously ounding the stock by the tack guide or iolder.

Preferably the machine will be organized to cause the bottom beating means to deliver ferent ualities. In the illustrated embodi-- ment 0 the invention the shoe is-mounted upon a ack or a heel spindle, this articular machine having been fitted up or heel seat lasting only, which is connected to the driving mechanism of the machine to change the vertical position of the shoe between-successive beating blows, the shoe being lifted to receive the second blow. This jack, which in itself is not a part of the present invention, also cooperates with the lastin means to obtain superior; lasting, particu arly of the heel seat of the shoe. For this purpose the lifting of the jack is timed to take place with relation to the movement of the wiper so thatixthe shoe is raised during the advance of the wiper thereover. This movement of the jack to grip the up or against the advancing wiper increases t e friction of the wi er on the upper as its proceeds inwardly romthe edge of the upper. This enables a stiff portion of upper material like the marginal portion of a heel stiffener to be bent over the edge of the last less P: abruptly than would necessarily be done if the shoe were fully raised when the wiper started forward. By raising the jack durmg the advance of the wiper the overbent upper material is drawn inwardly as it is (is pressed down so that it 1s drawn in over ing to the side beater a pluralit "ing to those shoe.

the edge of the lastinstead of being crushed down and bul ed outwardly at the side as might occur if the lifting of the jack followed the inward movement.

A further important feature of this'invention consists in the combination with lastingand pounding up means which may be arranged in any appro riate way in this combination, of means or beating the side of the shoe. Means is provided for impartof reciprocations at a period suitably se ected with relation to the operation of the lasting and tacking instrumentalities to be most eifective upon the intermittently advanced shoe. Theblows of the bottom beater are relatively heavy flattening blows while the blows of the side. beater are light tapscorrespondgiven by a hand operator to shapp the upper materials against the side of t e last. bottom rest mounted to roll over the shoe in the direction of feed has a narrow edge to assist in resisting lateral dis lacement of the shoe by the side beater.

n accordance with another feature of this invention successive blows of the side beater are delivered against portions of the up er which are different distances from the e ge of the shoe bottom. As shown this result is obtained by the relative timing of theside heater and the jack lifter whereby the beater "strikes, the shoe before it is raised to itshighest osition and again after it has been so raised with relation to the side beater. Preferably the beater strikes a sharp blow as distinguished from a ush or an increased pressure as has hereto ore been proposed, ust as'the wiper is completing its advance, and the action of the beater, wiper and risin jack serves to shape and produce a well de n'ed angular edge on the upper at the junction of the side and bottom faces of the It may be well here to state that the wi or, as well as the bottom heater and the si e heater, is a shaping means. within the meaning to be given to that term in this specification.

These and other features of this invention, including certain details of constructionand'more important combinations of parts will be explained in the following description and then pointed out in the claims.

Figure 1 is a side elevation of a machine embodying the present invention. Fig. 2 is a perspective view showing certain of the operating mechanisms. Fig. 3 is a sectional detail. I

The body portion of the machine may correspond ingeneral with the disclosure 'in said prior patent, the head 2 carrying I inserted by the driver 90 the block over the shoe bottom,

pulley 6. The camshaft carries a cam 88 connected by a lever 87 with a tack block supporting slide 84. Tacks are supplied by suitable mechanism to the tack block 20 while the latter is in its retracted position. In advancing to position for the tack to be wipe bending the upper materials over the last edge and wiping and the bottom rest, although laying them down into lasted position upon the innersole to which they are secured by the tack. Grippers may be employed as shown in said patent to assist the combined wiper and tack carrier in performing the lasting or they may be omitted as in the illustrated machine which is equipped for heel seat lasting. The shoe' is pressed upwardly against a bottom rest 12 which is mounted in a bracket attached'to the machine frame and carries a freely rotatable disk 14. The disk sinks into the shoe innersole when the shoe is forcefully pressed upwardly against it. This enables the rest to resist the lateral push of the wiper and the blows of the side heater. The shoe is supported and intermittently lifted by the jack comprising the heel spindle 22 movably sustained on the forward arm of a lever 24 fulcrumed on the post of the machine. The jack is normally depressed bya spring 25 acting on the rear arm of said lever which arm is connected by a rod 26, yoke 27 and spring pressed plunger 28 with a cam 30 located on the main cam shaft of the machine back of the cam 88 which operates the wiper and tack block and independent of said cam 88. The disk la-by reason of its thin shoe engaging edge, is adapted to sink into the shoe innersole when the shoe is uplifted t-hereagainst while the wiper 20 is retracted, thus allowing the shoe to be raised higher at such times than when the wiper forms the height limiting abutment. In the latter case the spring of the plunger 28 takes 11p the excess movement of the cam'30. That spring also compensates for differences in thickness of the work on the heel spindle. v The bottom beater {l0 is on a plunger 42 shown as operating in a substantially vertical bearing inthe bracket which carries the plunger may be arranged at any desired inclination to the plane of the shoe bottom. The upper I end of the plunger 42 has a suitableloose connection with the front end of lever 44. which is pivoted at 4.3, Fig. 2, and has its rear end operatively-connected with a side ram on a cam block 45. The rear end of the lever 44 is sufficiently below its fulcrum 43 so that pressure of the cam longitudinally against'th lever tends to swing it about 43 j ,asanaxis and to-raise the forward end with the plunger l2. The side cam'ishere shown as'having two drops 6 to impart has a narrow edge which cycle. The lever is impelled downwardly to give the beating blow by a strong spring 48 and the length of the stroke is limited by an adjustable collar 49 on the plunger so that the bottom beater cannot descend far enough to strike the side beater when no work is in the machine.

The side beater 50 reciprocates in a bracket 52 and has, as herein shown, a contact plate 54 that is pivoted near its lower end for an inward and slightly upward movement of its upper end, against the action of a spring 55, when the plate engages the work. Said plate has a formed face to correspond with the contour of the last and the described movement causes it totend to press the upper upwardly toward the side beater is operated by a stud 56 through a spring 58 which encircles the plunger 60 and is adjusted by a thimble ('32 carried by an arm of a lever 65. The upper arm of this lever has a roll in a groove 66 in the cam block 45. The groove is shownv as having an undulating contour which gives to the side beater six or eight short strokes in each cycle, thus effecting a light rapid tapping on the side-of the shoe as compared with the heavier flattening blows of the bottom bea ter.

The jackcam will preferably be timed to causeit to lift the shoe during the advance of the wiper over the upper so as to produce on the upper a combined o erbending and then an inward rubbing and downward crushing action. This cam will hold the shoe up only while the tack is being driven and then relieve the pressure and permit the jack spring to lower the shoe to avoid drag of the wiper thereover in the retreat of the wiper. The bottom beater cam is timed to strike a blow after the wiper has retreated to uncover the stock and While the shoe has been released from hard upward pressure, and said beater cam and the jack cam are timed to cause another blow to be struck and the shoe to be raised to meet the second blow. In the second rise of the jack the wiper is out of the way so that the shoe is pressed up against the thin edge of the bottom rest which sinks into the innersole and allows the shoe to rise higher so that, in effect, the second blow ofthe bottom beater on the shoe is harder than the first blow. The side beater cam is formed relatively to the wiper cam to cause said heater to strike before the shoe hasbeen fully raised and again while the shoe is pressed hard up against the wiper and this action of the side beater and the wiper serve to set the upper materials in an angulanformatio-n at the edge of the shoe. Tli'vertical movement of its . the shoe between the blows of the side beater .causes those blows to be delivered successively at different distances from theedge States- 1.
