LAS'IING-TACK FULLER.

To all whom 'it may concern: y

Be it known that I, LESLIE V. MILLER, 'a citizen of the United States, residing at 82() 1North Robey street, Chicago, in the county of Cook-and State of Illinois, have invented a new and useful Improvement in Lasting- Tack Pullers, of which thev following is` a specification.

My invention relates to an improved const ruction of machine for pulling out of lasted shoes and boots the tacks employed for temporarily fastening the upper to the sole preparatoryto sewing the parts together; and it relates particularly to an improvement in the type of machine for thepurpose employing a rotatory wheel adapted to have the lasted shoe moved relative to its periphery to present the tacks to be extracted to pullers projecting from a side'of the Wheel.

In the'accompanyi'ng drawings, Figure 1 is j a view in front elevation's'howing a plurality of my improved devices on a commonrotatory shaft; Fig. 2, an enlarged section taken at the line 2 on Fig.v 1 and viewed in the direction of the'arrow, showing a lasted shoe, in sectionfundergoing extraction of the. tacks that temporarily fasten the upper to the sole Fig. 3, a similar section taken at the line?, on Fig. 1 and viewed in the direction of the arrow, showing the shoe undergoing extraction of the tacks which are driven intol the last through the shoe-sole; Fig. 4, aplan view of the showingmade in Fig. 2, and Fig. 5,V a similar view of the showing made in -F ig. 8.

In its preferred embodiment my improved device involves two tack-pulling wheels of relatively larger and smaller diameters on a common rotary shaft, one being adapted fory extracting the projecting tacks which fastenr the upper 'to the sole, and the smaller -for extracting the tacks thatv fasten the sole and counter to the last. On a pulley-equipped shaft of any desired length, journaled in suitable bearings,

one of which is represented at 7 (Fig. 1)- asdepending from a table, bench, or other suport, indicated at 8, is'secured-to rotate with it a wheel 9, which is preferably provided with a circumferentially grooved periphery, the groove 10 shownbeing of V-shapein cross-section; and similar tack-extracting wipers 11 are shown in the form of blades let rigidly into the periphery of the Wheel at diametrically opposite points thereof, to extend across it and project beyond its outer-face. Only Specification of Letters Patent. Application filed September 30,1907. Serial No. 395,087.

Patented Aug. 25, 1908.

R @ISSUED one,'or more than two, of these blades may, however, be provided onV the wheel. Adj acent to the wheel 9 there projects from about the shaft a stationary bent arm 12 carrying on its outer end a head, shown as a disk 13 journaled on the arm-end to extend over and adjacent to the periphery of the wheel and afford a guide.

On the shaft, a suitable distance from the 'wheel 9, is secured awheel 14in all particulars like the wheel 9 except that it is smaller in diameter and that the similar blades 15 which are rigidly let into the periphery to extend across the circumferential groove' .16 therein, do not project beyond a face of the wheel. j

To operate the device for extracting the tacks 17 which fasten the upper 1S of a shoe 19 on a last 20 to the sole 21, and the heads of which project .in series about the inturned edge of the upper, the operator presents the shoe, as represented in Fig. 4, to the periph-` ery of the rotatory wheel 9,' by applying the usual channel about the shoe-sole to the rotatory disk 13, the edge of which thus enters the channel, causing it to guide the operator in turning the shoe, crosswise of the periphery of the wheel, on the disk toy present the tacks successively to the ath of the projecting ends of the blades. n originally placing the shoe a tack 17 may be abutted against the outer side of the wheel, as represented in Fig. 4, and when the blade 11, inthe rotation of the wheel, encounters that tack it extracts it by wiping it out. Then the operator turns the shoejto bring the next succeeding tack to abut against the wheel-side and to be ile the guide 134 ticularly'usefu in extracting the counter and sole'tacks', as hereinafter described with reference to thewheel 14, when the wheel 9 is used, as may be, for that purpose, this groove being further useful in reducing to the minimum the friction ofthe shoe against the periphery of the wheel in moving it across the same. As willbe observed, the blades 11 not only extract the tacks presented -to them,

but in doing so also wipe down the free edge portion 'of the upper.

To pull the tacks 22 that are driven into,

the last throughthe sole 21, theoperator applies the sole at a tack therein to the grooved periphery of the wheel 14, with suHicient pressure to cause the sole to warp, at thepoint of a-p lication, into the groove and thereby sliglitly protrude the 'head of the tack, if it be fully driven', into the path of the blade 15, which, when it encounters the tack, will extract it; and the same operation may be similarly performed on the counter of the shoe tov extract the tack usually driven through it into the last, though none is shown in the drawing. y

By providing the two blade-equipped wheels 9 andl 141l in suitably relative position y cess to a plurality of operators.v

What I claim as new, and desire to'secure by Letters Patent, is-

1. In a tack-pulling machine 'for lasted' shoes, the combination of a rota-ry shaft, a Wheel supported on said shaft to adapt a 4lasted shoe 'to be moved in a path lengthwise of its series of side-tacks across the periphery of the wheel, and an extractor-blade projecting from a side of said wheel to rotate therewith in a plane intersecting said path, for the purpose set forth. i'

2. In a tack-pulling machine fory lasted shoes, the combmation of a rotary shaft, a wheel on said s haft having a circumferentially grooved peri hery, and an extractor blade on said whee extending crosswise of its periphery, for the purpose set'fofrth.

3. In a tack-pulling machine for lasted shoes, the combination of a rotary shaft, a peripherally grooved wheel on said shaft, an extractor-blade extending across the peri l1- ery of the wheel and projecting beyon aside thereof, and a guide supported to extend adjacent to Asaid periphery, for the purpose set forth. y
