provements in Lasting-Machines; and we do hereby declare the following to be'a full, clear,and BXtl-CtdGSCllPtlOll of the invention,
such as will enable others skilled in the art to which it appertains tomake and use the I same.
chine, this plaiting of Wringmg to lasting machines,
points where itis secured bulges or bellies out and in lasting the shoe this portion of the upper is ordinarily taken careof by plaiting it over'the ,insolef When the shoe is lasted by. hand, or in what is known the bed or wiper type of lasting mathe fullness of the upper isaccomplished by wringing the upper with a pair of hand lasting pincers. consists in seizing the margin of the upper with the pincers and, while pullingrotatingthe pincer jaws to the right or left by, a twist of the wrist. the upper a turning movement is imparted to the pincer jaws 'aboutan axis extending obliquely to the horizontal, or plane of the shoe bottom, and in the general direction of the pulling. movement. It has been found in practice that a rotary or turning unwement of the pincers about such an axis lays thein'argin offthe upper snugly to theinsole and produces the most effectual plaiting.
The object of the present invention to provide mechanical means for laying the fulled portion of the upper to the last as effectively as it can be done by hand.
In accordance with this object one feature of the invention contemplates the provision in a machine of the general type specified, which already in the mechanical operation of its pincers closely follows the up'draw and overdraw movements used in hand lasting, of mechanical means for im; parting to the pincers, in addition, a turning movement for-plaiting the fulled upper at Specification of Letters Patent. Application filed April 20, 1908.
that type of lasting In wrmgl n g supporting Serial No. 427,972;
the toe, similar in its action on the upper, and in its etfect, to hand wringing.
In the preferred embodiment of the in-' vention the pincer their gripping faces at a substantial oblique angle. to the horizontal and means is pro- Patented Feb. 20, 1912,
]aws are mounted with vided for rotating said jaws about an axis in the plane of said v plane substantially parallel thereto. "The turning movement thus takes place about an axis extending in the general direction of the'overdraw movement, as in The plaiting movement thus mechanically imparted to the upper is similar in all respects to the plaitin'g movement obtained by hand manipulation of the pincers.
To the accomplishment of this object and such others may hereinafter" appear, as will be readily understood'by those skilled in the art, the invention comprises the features and combinations of parts hereinafter described and particularly pointed out in the appended claims.
The various features of the invention will best be understood from a description of the prefer-rm; embodiment thereof illustrated in the accen'ipanying drawing, in which the invention has been shown for purposes of description as applied to the type of hand method lasting machine exemplified by the United States Patents to S. WV. Ladd and R. F. Mclfieely, No. 584,744, and S. W. L add No. 597,321. A y
In the drawings Figure 1 is a side elevation of a portion of a hand method lasting machine of the type above specified, With'the improvement contemplated by the present invention applied thereto; Fig. 2 is a front elevation of the parts shown in Fig. 1; and Fig.3 is a detail of thepincer jaws shown in Fig. .l, viewedin' the direction indicated and Mc-Feely patent above referred to as jaws, which, by the i the pincer mechanisms described imparted to them the to place an upper in overworked position on a last, viz: the pulling or updraw movement, the outward or overdraw movement, and the sidewise or transverse movement used with a rotary movement for plaitin the upper around the toe. In the present invention, instead of mounting the pincer directly in this bracket in the patent, have hand lasting.
gripping faces or in a movements necessary as in the patent,
a sleeve 4, depending from-the pincer lifting lever 28 and passing through the.
bracket, supports an auxiliary bracket (3 which in turn sustains a carrier 8 for the pincer jaws. This carrier 8 extends at an oblique angle to the horizontal, the direction being upwardly and outwardly from the plane of the front of the machine and in the general direction of the pull in over-- maintained open by means of a small coiled ping faces.
against the force of the spring l6 there 18 v v to,
Asv is well known to those skilled in the art, for the most complete andefiective manipulation of the upper, and particularly in lasting the toe, the pincers should be turned as well ,as moved sidewise or transversely in order to plait and-lay the fullness of the uppc at this part of the shoe snugly to the insole. To this end means is provided forimparting a rotary movement to the pincer jaws in addition to the transverse movement. The mechanism for moving the pincer's trans versely may be and is similar in all respects to that shown in the patent to Ladd and McFeely heretofore referred to. In that patent this mechanism for moving the pincers transversely is also utilized to impart a rotary movementto the pincers about an axis comprised by the vertically arranged rod for closing the jaws, which COTI'OSPOIHlS to the rod or plunger 20 herein described. This is accomplished in the patented construction by means of a gear on the rod and a transversely movable rack which engages therewith and is given a reciprocatory movement from themeel'ianism for moving the pincers transversely. It has been found ex- 'crank arm 42.
pedient in the present instance to utilize this reciprocatmg member 1n imparting the desired rotary movement to the pincer jaws herein described. This bar is shown at 22 and is formed with plane surfaces, thus pivoted u on the pincer lifting lever '28.
The outc end of the lever 36 has connected thereto, also by a universal joint 38, the upper end of a link or red 40, the lower end of which is pivoted to the outer end of a The crank arm 42 is journaled upon a stud 44 mounted in the auxiliary bracket 6, and this crank arm has connected thereto a toothed segment 46, also journaled upon the stud 44. The segment 46 is adapted to intermesh with a second seg ment 48 on the outer end of the shank 10 of the pincer jaws, which, as before stated, s
journaled in the obliquely mounted carrier in. 'With'such a construction as that just de .scribed, it is seen that when the pincers are moved transversely, by the mechanism described in the Ladd and McFeely patent, the bell crank 2430 is rocked about its pivot 26, which in turn imparts a rotary motion to the segment 46, thereby-rotating the segment 48 and the shank 10 of the pincer jaws which in'iparts the desired turning move ment to the said aws. In order to maintain a constant engagement between the pincer jaws and the jaw closing plunger 20 during the turning movement, one of said parts, as illustrated the upper jaw 14, is In'ovideil with a bearing surface 50 formed in the present embodiment of the invention as an arc-shaped bar of sullicient length to allow for the oscillations of the pincer jaws.
Itwill be noted that when the pincer jaws are in gripping position they are maintained by the pincer carrier at a substantial oblique angle to the horizontal, the angle being'of such amplitude that, when the pincers are moved downward toward the sole 7 to gripthe margin of the upper, their jaws \Vlll extend 1n planes at each side 'of the upper as it projects above the last bottom.
\Vhile the described angle of the pincer carrier is not a lixed'obliquc angle, except during the updraw n'1ovement, because theforward swing of the pint-er carrier bracket during the overdraw movement will necessarily alter'lhc angle of the shank of the pincers to the horizontal, such movement, as will be apparent to those skilled in the art, is never sullicient to change the angle are supported at an angle permanently ob-- position or direction of movement of the importance. r
. lars are essential, since they may be varithroughout the lasting operation, and means for imparting a turning movement to the lique to the horizontal, pincer jaws for seizmovementto said-jaws, and means con bottom, throughout the lasting operation.
Thls is believed to be an important feature froman oblique angle. In other words, the construction is such that the pincer jaws liqueto the horizontal, or plane of the shoe of the present invention as ithas been found in practice to assist in the ,ditlicnlt work of shaping the upper to the last, particularly at the toe. I
