I mACHlINE FflR OPERATING ON SHOES.

Application filed June 3,

This invention relates to shoe machinery, andis illustrated as embodied in an apparatus for operating on the insides of shoes. e In making turned shoes with sewed heel seats, the lining is not se ved in at the bottom around the heel seat, butis attached by ad-' hesive after the shoe ha been turned, a shank piece being thereafter ins'erteditocover the margin of the lining at the heel seat, and to extend forward approximately to the ball line. So far as I am aware, these various operations of securing the lining and shank piece in place have always been performed by hand, the adhesive beine' applied by a a than by hand. To this'end the invention in one aspect, provides a novel and compact mabrush, the lining laid or smoothedagainst the adhesive by the fingers of the operator, and a-shank piece thereafter inserted inth'e shoe.

An object of the invention,- accordingly,

isltopimprove the making ofturned shoes'by providing mechanical means to perform these i Iv operatlonsinore quickly and more uniformly chine whicln as illustrated, comprises means for coating the inside counter portion ofa shoe with adhesive, expansible members for pressing the lining against the adhesivecoated surface, and means for securing a shank piece in the shoe While illustratedas especially adapted fl'or performing-"the described operations, the severalinstrumentalities employed embody, in variousftleatures,

broad novelty, and it is not the intention to limit the invention to. the performance of these particular operations or to turned shoe manufacture. {The novel features relating to the adhesive coating means are not however claimed herein, these features being claimed in a divisional application, Serial'lio 232,330, filed November 10, 1927.

After the coatingof adhesive has been applied to the inside of the shoe, and the lining has been turned'right side out again, it is necessary that the lining be smoothly pressed against the coated surface. So far as I am aware, no mechanical ineanshas previously been designed for applying outward pressure" in this manner, such work always having been done by hand. In this aspect my invention contemplates the use of-members to be inserted in a shoe, and means to open or expand theinj into engagement with the inside of the shoe, applying an outward pressure adhesive-coated inner surface of the shoe.

Fig. 16 is a view generally similar to Figs. 6 and 9 showing a modification according to which the lining smoothing and staple in-V sorting mechanisms are arranged for simultaneous operation.

Thegeneral organization of the machine comprises a base 20 supporting coating mechanism 100, lining. smoothing mechanism 200,'

and staple forming and inserting mechanisn'i 300. The machine is intended to operate on a shoe S (Fig. 11) which has just been turned. in which the lining; L is pulled inside outand a. molded counter C is inserted by hand. As shown in Fig. 1.2 the first step is the coating of the interior of the shoe with adhesive by the brush 102 of the coating inechanisn'i 100. The second step comprises rcplacino the lining and smoothing it down against the adhesively coated counter portion of the shoe by the wipers 202 of the smoothing mechanism 200. After the smoothing of the lining a Shank piece F (Fig. 13) is placed in the shoe over the inturned bottom margins of the lin ing and counter, and, as shown in Fig. 15;

the last step is the insertion of a staple M to fasten the shank piece F to the sole T. Fig. 13 shows the relative positions inthe finished shoe of the sole T, the counter C, and the shank piece F which is reinforced by a stiffener P and is fastened to the solo by a staple M. 1

According to the modification shown in F ig. 16 the lining smoothing mechanism and staple forming and inserting mechanism are mounted in one head; When this modification is used the shank piece is carried by prongs 400, and is placed in the shoe thereby at the time the lining is smoothed by the wipers 202. At the end of the lining smoothing, movement the staple is inserted through the shank piece to fasten it to the shoe and wipers 202 and prongs 100 are then withthe main shaft 30 and various levers and gears driven thereby are mounted on secondary shafts 3a and 36 (Fig. 10).

The coating mechanism 100 comprises a.

brush v102 carried by a shaft 104- wniclris mounted for vboth rotary and axial movelowered by a coil spring 121 and is raised by a cam 126 acting against cam roll 1 8. Cain 126 is secured to a sleeve 130 which also carries .a Horton clutch 132 arranged in the usual way to be secured to the continuously rotating shaft 30 or to be released therefrom by the engagement of abutments 13- 1 and 188 mounted on a bell crank 136. with a pawl lever 1-10 opcratcdby treadle rod 1 12 and treadle 1-11 1. A bracket 146 on the support 20 carries a reservoir 1 18 for the adhesive.

By the above arrangement of parts the brush 102 is continuously rotated and is controlled by treadle 14:4: to be raised axially out of the adhesive in the receptacle 148 by the first depression of treadle 14A and lowered again into the adhesive upon a second depression of this treadle. If preferrec, the abutment 13% might be omitted on the Horton clutch in which case operation of the treadle 1 1% would result in axial movement of the shaft 10 1 to raise brush 102 out of the adhesive in receptacle 148 long enough to place shoe thereover to coat the interior counter portion and to reinove it again, after which the brush would automatically descend again into theadhesive.

The forward part of finishes is protected from possible engagement with the brush 102 by a shield or support 150 as best shown in Fig. 12, which also acts as a gage to position the shoe.

The reservoir 148 is hermetically sealed by a cover 152, secured thereto clamping nuts 158; A filling opening; in this cover is non mally sealed by a threaded cap 160. The central portion of thecover is formed into an inner receptacle 15 1. of somewhat larger diameter than brush 102, in the bottom of which are holes 156 communicating with the inside of reservoir 148. By this arrangement, when brush 102 is raised, adhesive flowsfrom reservoir 1 18 into receptacle 154 up to the top of holes 156,- at which height it is held by the pressure of the atmosphere. When brush 102 descends, it acts as a pump or piston, forcing the fresh supply of adhesive upward between the brush and the wall of receptacle 154, to all parts of the brush.

After the interior counter portion of a shoe hasbeen coated with adhesive by he above described mechanism. as shown in Fig. 12, the

lining L is folded down into'place and is frame of the machine, and is yieldingly held jagamst downward movement by engagement of lug 210' with a compression spring 212 whose tension may be adjusted by means'of a set screw214; V

Inside of the. )lun 'er 204 1s SlIClID l b b mounted a hnk 216 attached to the knuckle of a toggle 218 the ends of which engage lugs link 216 is depressed,

220 on the wipers 202 to expand them when thereby straightening the toggle 218. l Vhenthe link 216 is rasied a spring 222 acts to contract the wipers. Threaded on the upper end of link216 is a sleeve224 which may be locked in any desired position by a lock nut 226 and which carries pins 228 embraced by slots in theforked end of a bell crank lever 230 mounted on the shaft 36. Bell crank lever 230 is rocked to pull upwardly on'the link 216 by a spring 232 and is rocked to depress link 216 by a cam 234 acting against cam roll 236. The cam 234 is carried by a'sle'eve 238 which also carries a Horton clutch 240 controlled in the usual way 'by V treadle rod 242 and treadle 244.

Also mounted on the sleeve 238'controlled b treadle 244 is a cam 246 enn'a 'in a cam c t: Q

roll 248 carried by lever 250 mounted on sleeve 252 on the shaft 34. The sleeve 252 carries an arm 254 which supports a cup 256 shaped to fitover the outside counter. portion of'a shoe and to provide support for the exterior side,

rear and bottom surfaces of this portion of the'shoe. The cup 256 is yieldingly connected to the arm 254 by plunger 258 and spring 260 and the position of the cup 256 may be adjusted by longitudinally moving the plunger 258' by means of a nut'262 threaded thereon.

I At the conclusion of the downward stroke of plunger 204 it is locked by a pawl 264 havingan integral lug 266 pressed by a spring 268. The lower end of this pawl snaps over the'tep of plunger 204and holds it during the firstv part of the upward movement of link 216, thus contracting the wipers betorethey are bodily moved. When the bottom of a cutoutportion 272 on link 216 cams against the rounded head of pawl 264, it forces the pawl back against the tension of spring 268, releasing plunger 204 which is then returned to upper position by spring 212. A setsoiew.

270 may if desired be provided to govern the tension of spring 268-. V p p In the operation of this part of the machine the shoe is placed over the wipers 202 and the treadle 244 is depressed to cause sleeve .38 to be rotated through one revolution by the shaft hesive coated surface toggle 218 to engage the plate 206 thereby forcing the-wipers bodily downward inengagement with the lining and compressing the spring 212. The end of this stroke is shown in Fig. 14. y T

The lining having been smoothed down as described, a shank piece F is inserted in the shoe tocover the shank and heel seat and the lower margins of the lining and the counter,

as willbe apparent from Figs. 13 and 15. i

The shank piece F is secured in thisposition by a staple M which is formed and driven by the staple inserting mechanism shown in Figs. Sand 10 and indicated generally by the reference numeral 300. As staple inserting mechanism of this general character is wellknown only a brief description of the various parts will be given. The staple is formed froma wire 1V fed from a spool 302 (Fig. 1.) by any suitable type ofjfeeding mechanism operated by levers 304 and 306 operated by cam 308 on shaft 30. r The wire is fed over an inside former 310which is withdrawn after the formation of the staples by a bell crank lever :312 operated by a face cam surface314 on cam308. The wire is formed about this insideformer by anoutside former of'any suitable and well-known construction operated by arms 316 secured to a sleeve 318 on shaft 34 to constitute a bell'crank lever carrying a cam roll 320 also bearing against the cam surface 314. After the formation of a staple by the inside and outside formers, and the withdrawal of the inside former 310 by its bell crank 312, the stapleis driven by a plunger depressed by an arm 324 which is swung downwardly by coil spring .326, as

soon as the cam roll 328 carried thereby rides over the point 330 of cam 332 on shaft 30.

Cams 308 and 332 are mounted on a sleeve which also carries a Horton clutch 334 arranged to be secured to shaft 30 during one shoe is removed.

At the end of this smoothing operation a staple is formed and driven to fasten the shank piecein place, whereupon the counter support or heel cup 256 is withdrawn and the As the wiper operating mechanism and the staple forming and inserting mechanism illustrated in Fig. 16 are the same as above described, no further description thereof is deemed necessary. It will be noted that when this form of the apparatus is used one rotation of shaft SOis suliicicnt to position a shank piece in a shoe, wipe down or smooththe lining, and staple the shank piece in place. 7

It is believed that-the operation oi this machine will be understood without further explanation from the foregoing description. lVhile theinrention has been illustrated and described as embodied in a machine for operating on turned shoes, it will be appreciated that in various aspects it is capable of other uses andit is not the intention to limit its scope thereby or otherwise than by the terms of the appended claims.
