- Be it known'tha't I. E GLID I. LA CHAR PELLii, a'citiz en 'o'l the' United States,residing in Brockton, county of Plymouth, Commonwealth of Massachusetts, have invented a certain new and, useful Improvement in Shoe-Turning Machines, of which the fol lowing is a. specification, reference being had to the drawings accompanying the same and forming apart theie'of.

"My present invention relatestoshoe forepart turning machines and is herein shown asii'applied, foniconvenieiic'e only, to a shoe turning machine oft-he description shown in my patent for shoe turning machines, No 1,336,750 issued Aprill 1920. The shoeturning elements therein shown, being'trans posed to theiront Oftl1 machine frame in the present patent application, to lower same for the convenience of the operator, which feature is .not, of course, patentable and which forms no part of my present inventiOIi; c Hy present invention relates to shoe turning machines that are provided with soleclarnpingrmembers and contemplates theimprovement of such machines, but, I Want it well understood that'my invention does not relate'solely to thQ sOle-clamping members of such machines and that it may be embodied in some of the remainder of the shoe turning elements of shoe turning machines,

when not embodied in the clamping Inembers, a'nbl that the appended claims must be interpreted in that broad sense. Furthermore, my present invention is not an improvement upon the machine shown in my Patent No, 1,336,750Jissue d April 18, v1920ibecause it is preferable tohold' a shoe sole dir edtly with. the hand, as described and claimed therein, and one of the advantages of solholdinii' directly withfithe hand is that the operator may thenfeel any undue strain. upon the shoe and may immediately release the shoe fromlthe tui-nin elements to immediatelycause the strain'in', g action thereof to be terminated upon the toe-end of the shoe; r V

I .;l1o\vev-eir, contemplate improving shoe forepart turning machines which are provided with} sole clamping menibers, for the ieason that prior tomy present invention,

some shoe forepa'rt turningfniac'hines,pro:

vided with Cl2l 111plng 11'16fi1l31'S adapted: to clamp the sole at itsflheel part and some-shoe forepait turning machines, if-later date,

provided with clamping membersfadipted to clamp the sole at its shank parthave been made, but have not, so far as I am aware, gone into practical use, particularly bee-arise of objection to theuamagemusea to thet'oer enact the shoe by the shoe turningmember. being forced into the toe-end of the shoe too far, and especially so with machines thatgare power actuated, so as to punch out theft end to an extent suiiicient' to cause serious damage 4 I improve such machines for thefur'tlier reason that I intend introducing to, the shoe making trade, by the introductionof in present invention, the makingof spcialturn shoes having extra heavy leather soles',loi' correspondingheft, or of heavier heftflas that of outsoles' o'f'woinensheavy grade Welt or McKay shoes, as now b e ing n'iiadel 5 1,

Such, special turn shoes favorably compare to Goodyear welt shoes, notably in 'womens make, and such shoesnia-y be properly turned by my novel sha ter-hing machine, herein disclosed. Womens' tiirn shoes, as herein contemplated, are adapted to street wear and being lighterin weight and more flexible and cheapertoinanufac, ture than Goodyear welt shoes iandltherefgre comparatively cheaper in price to the consumer inay be given the preference over Goodyear welt' shoes, but, so far as I" am aware, such shoeshave never been made in the generalrnn of shoe factories, because'o f the difficulty oi turningthe foijepa'it'lw hand, or because of the objectionable feature of puiichingout the toe-end of the shoe by machine.

7 Such Special turn shoes i'c'quire. to' 'lie positively held against'the strain of th ejffoi part turning operation; soleclamping' i ent hers such as herein disclosed,but, it isto be appreciated thatalthough my present invention "isjintende'd for turniiig the forepart of such special shoes, it may be; i'isefully employed for turning the forepai-tof tau-n shoes having ordinarv'soles, such usediii the making oi turn shee s in the general run of shoe factories and the appended 'clain'is,

must be so interpreted since the possibility of damage to the toe-end of shoes is always existent regardless of the kind of soles incorporated into the shoes.

The object of my present invention is to improve shoe forepart turning machines, that are provided with sole-clamping members, so that the possibility of damage to the toe-end by the shoe turning elements of such machines is practically eliminated and I attain this object by anovel arrangement of the sole-clamping members illustrated in the accompanying drawings, in which:

Figs. 1 and 2 are respectively side and front elevations of a shoe turning machine embodying my invention.

Figs. 3 to 6 are detailed views illustrating the different steps in the turning operation of the heel part and forepart.

7 illustrates a detail of the crosshead.

The complete machine is illustrated in Figs. 1 and 2 and comprises a base 10, having an upright support 12, mounted thereon and also a bearing 14, in which the main shaft 16, is journaled, said shaft having a driving pulley 18, on one end and a pinion 20, on the opposite end, the latter being arranged in mesh with a large gear 22, mounted on a shaft 24, also journaled in a bearing on the base. The upright support 12, is provided with vertical guideways 26, in which a cross-head 28, is mounted to slide, and a connecting rod or link 30, is pivoted to said cross-head at one end and eccentrically connected to said gear 22, at the other end, so that as the gear is rotated said cross-head will be reciprocated.

A round bar 32, (which I hereafter term a turning member, as it corresponds in shape and function to the ordinary turning iron, generally employed in hand turning) is fixed to an arm extending from the support 12, in a vertical position, said turning member being provided with the usual friction roll 34, in its upper end, and a tubular cylindrical sleeve or plunger-.36, is slidably mounted on said turning member 32, and is connected to the cross-head 28, so that said sleeve will be caused to reciprocate on the turning member 32, when the main shaft is driven. The upper end portion of said sleeve is tapered or beveled at its front side, forming a beveled face 40 and is provided with a projection 42, at its rear side, the under side of said projection being corrugated or provided with teeth and a co-acting member 44, is pivoted to a shaft 46, said shaft extending through the cross-head 28, which is slotted to receive the said co-acting clamping member as shown at 28*, Fig. 7, and a hand lever 50, is secured to the protruding end of the shaft 46, wherebythe operator may control the clamping action of said member 44, during the shoe forepart turning operation and a spring 52 acts to move the member 44 out of operative position and against a pin 56, which limits its movement under the action of said spring.

This novel arrangement of clampingmembers permits the operator to immediately open the clamping members after the toeend has been turned thereby and by the turning member 32, and thereby the damage to the toe-end of the shoe by the turning member 32, is overcome.

A bracket 58, is rigidly secured to the rear side of the support 12, and is extended upward and then downward in gooseneck form, the depending end thereof being provided with a heel turning cup 60, of common form, said cup being interchangeable to adapt the machine for shoes of different types, when the heel part and the forepart are turned by a single machine, as in the present case, and the said cup is held in inverted position directly over the sleeve 36, so that, when the latter is lifted, it will be passed into said cup adjacent its walls.

The operation is as follows: While the sleeve 36, is being moved up, the operator places, with his left hand within the shoe forepart, the heel portion of the shoe on the cup 60, so that the rear part edge of the latter engages the seam which I connects the shoe upper to the sole. The upper end of the sleeve 36, is shaped to correspond to the interior face'of the cup, and as it moves upward it engages the soleseam of the shoe and forces it inward, or breaks it, as commonly termed, and, during the latter portion of its upward movement, it will engage the sole of the shoe and will flatten the heel-seat against the bottom of the cup, which is preferably covered with rubber for that purpose, as indicated in Fig. 3, and thus the heel part of the shoe is turned in the ordinary manner, as indicated in Fig. 4. The sleeve then descends and during its downward movement, the operator presses the heel of the shoe downward and out of the cup with his right hand and slides it rearward on the upper end of the sleeve and then bends it over the end of the projection 42 and then the operator, holding the shoe over the end of the sleeve with his left hand still within the shoe forepart, moves the lever 50, forwardly with his 1 right hand and the clamping member 44. is thereby set in engagement with the sole at its shank part and firmly clamps it against the projection 42. The operator, still having the left hand within the forepart of the shoe, spreads the shoe upper and bends the sole longitudinally around the sleeve 36. The sleeve is, meanwhile, descending and by this time will have been moved down until its upper end is below the level of the roll. 34, so that the sole will then be en gaged by said roll. The sole being held &
