This invention relates to shoe machinery, and is illustrated as embodied in an apparatus for operating on the insides of shoes. The presentapplication is filed as a division of my copending application Serial No. 174,701, filed June 3, 1921, whichhas maftured into Letters Patentof the United States No. 1,693,667, granted Dec. 4, 1928 ,and

discloses theinvention in a form adapted for use in connection w th the operation of securing the linings in turn shoes, although "the invention is not limited to such use.

Inmaking turn shoes with sewed heel seats, the lining is not sewed in at the bottom'around' the heel seat, but is attached by adhesive after the shoehas been turned, a shank piece being thereafter inserted to cover 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 operationsof securing the lining and shank piece in place have always been performed by hand, the adhesive being applied by a brush, the lining laid or smoothed against the adhesive by the fingers of theoperator, and a shank piece-thereafter insertedin the shoe.

One object of the'present invention is to improve the making of turn shoes by providing mechanical means for coating the inside of a shoe with-adhesive so that'when the lining is subsequently laid itwill be held in place by the adhesive. With this object in view, one feature ofthe inventionresides in the provision, in a shoe machine, of a fixedly mounted support for a shoeand means for coating the lateral faces ofthelinsidel lofa bottomed shoe supported thereby.

The illustrated mechanism; for applying the adhesive comprises a coating device. in

which a brush, orequivalent' applying mem- I ber, transfers the liqu'id from a receptacle and applies it to the inside of the shoe. To secure uniformity inthe coating, the brush is shown as rotated bysuitablepower-driven mechanism, and to insure that the adhesive will'be applied correctly, 'a shield member serves also to guide'the shoe'toposition over the brush and also protectsthe fore portion applying mechanism, and I *FJgJfZiS a View of aturn thereof from possible engagement with the brush 7' l 7 i One ofthe great difficulties in any adhesive-applying device is the readiness with which practically all adhesives'cake or'crust 'under the influence of the atmosphere. I

have arrangedmy improved apparatus to minimize this action by restricting the access of the atmospheretothe adhesive in the res- 'GIVOITC; Avery small opening, butslightly larger than the cross-section of the brush, is provided for the insertionof the brush,- and even tl11s small opening is normally almost entirely closed'by the brush. To make this possible, the'brush itself is mounted in a novel manner-for axialmovement into and out vof the receptacle; Moreover, only a small quantity of adhesive is supplied'to the brush at anyone' time, being just'sufficient for the next shoe, and the remainder is kept in a sealed reservoir where the atmosphere cannotieach it. This" small quantity of fresh adhe'sive is supplied each time the brush is raised to a small receptacle, slightly larger than-the brush, sothat the brush itself, in descendlng, acts as a piston to force the adhesive upward and distribute it to the whole surface ofthe brush, 7 Y These and other features of the invention, 1nclu'd1ng deta ls of construction and combinations of parts,-will"be apparent from the following description of the illustrative embodimentof the invention shown'in the accompanying drawings, in which Fig; 1 is a view, partially in sideelevation and part ally in section, of thefadhesive- A i shoe, partially broken aw ay-,-1llustrating the manner in which the inside of thejshoe is coated with adhesive-2 mechanism 100 comprises a The coating jbrush 102 carried bya-shaftlO which is mounted for rotation thereby to turn the brush aroundits axis and-for axial movement to carry the brush from a lower position where it receives adhesive to araised applying position. -The--shaft 104 is rotated continuously during the operation of the ma chine byatrain of gears 106, 108, 110, 112

and 114. Gear 106 is fixed on a drive shaft 30 and the gear 114 is provided with a key or lug riding in a keyway 1.16 of the shaft 104. By this arrangement the train of gears is continuously driven and shaft, 104 is 1'0- tated by gear l l i' in both raised and lowered positions. A sleeve 118 is secured to the shaft 104 in any desired and well-known way to permit rotation of th'e shaftiw-ithin the sleeve and is arranged to be' raised and: lowered by a lever 120 acting through a pin-and-slot connection 122 to move the shaft l04 axiallya The lever 120 is lowered by a coil spring 124% and is raisedatthewillof theoperator by a cam 126 acting against camroll 128' G am; 126'is secured to a 'sleeye (not shown) which also carries a Horton'clutch 132 arranged inthe usual way tobe securedv to'the shaft 30 or to be released therefrom by the engagement of, abutments 13 1, and 136' with a pawl 138 mounted on abell-cranklever'140 operatedby treadle rod, -142 and a treadle (not shown) i; The shaft 30lis adapted: to be connected with a suitable source of power were berotated constantly during the "operationr"oi themachine. A bracket 146 on the support 20 carries a reservoirf148 tor -the adhesive; H V r 5 By the "above ar rangement; of parts the brush 102 is continuously" rotated'and is con-, trolled by the treadle ,tobe-raised axially out 7 of the adhesive in the" receptacle, 1%18" by the first, depression of. the treadle and lowered againinto the adhesive-upon a second der :pression, ot the tread'lel I tfpreferred, the

The forward part of the shoe-is; protected from possible; engagement w-ith the brush 102 ashoehorn-like shield or -support 150 fixedly supported-outofcontact with said br ush, as best shownrin Fig; 2,jwhich alsoactsas a guide-when positioning theshoe over "the brush iorthe application of; paste to the inside of the shoe.

The reservoir-148 ishermetieally sealed by a cover 152 seeuredthereto byclamping nuts 158. A-jfilling opening in this COVGPIS normally sealed by a threaded cap 160. a The central portion ofthe cover is formed' into .aniinner receptaclelfl, of slightly larger diameter than brush 102, in the: bottom-of which are holes 1156 communicating withrthe inside of reservoir; 148.. -Bv this arrange- ,ment,when;brush 102 is raised, adhesiveflows from reservoir 148 into receptacle'1'5 iupto the top of holes15 6, at-which height it is held by the pressureof 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 brus a The machine is particularly designed for usein applying cement to the inside of a bottomed shoe S which has just been turned andin which the lining Liis pulled insideiout, amolded counter (1 having .been inserted by hand in the shoe. In the operatio'x'i'o'fthemachinet'he applying brush 102 will be raised from the receptacle 154 in which it has become coated" withcement, by the manipulation of the operator-controlled treadle rod 1 42 acting through the lever '120, will cause the brush to bevraisedto a: position adj acent to theshield or support 150, in which position a portion oftheperiph'ery of the brush will be -guarded by'saidshield. At the same time, the balance of the periphery and its lower end will be exposed to permit the free presentation of ltlielateral faces of the inside-of thecounter end of the shoe S to the .applyin'ggbrush aswindicatedin Fig. 2.
