METHOD OF APPLYING ADHESIVES TO COUNTERS.

Application fi1ed September 22, 1923. Serial No. 664,248.

This invention relates to a method of applying an adhesive to the counters of shoes, as the coating them with paste prior to assembling with the shoe-uppers.

6 In assembling the elements of an upper, this including inserting a counter between the rear of the quarters and the lining, it iscustomary to first coat the counter with paste, to'cause it to adhere to the associated 10 elements, and unite all into a firm structure which will resist fulling, wrinkling and like displacements tending to affect the appearance and comfort of the finished shoe. The practice varies as to the particular portions of the counter coated; but it is desirable to thus treat the inside and outside of the body or upstanding portion, so that it may be joined both to the upper-leather and to the lining. It is unnecessary to paste the flange 2 of the counter,-which is firmly attached to the upper-elements and insole by the assem bling tacks, and often also by the heel-attaching nails. So far as we are aware, the paste has heretofore been applied by the 5 use of a brush held in one hand of the operator while the counter is grasped in the other hand, the opposite sides being successively coated, and no particular attention being paid to the area covered. This proc- 80 ess is wasteful of both time and paste. An

object of our invention is to provide a method of pasting counters by which the coating of a considerable number may be effected simultaneously, with precision as to the surface covered and resulting economy in the adhesive used. Our method is also cleanly for the operator, it being unnecessary to touch the coated surfaces, or expose the hands to contact with the coating in-- 4 strumentalities. a

As herein illustratively set forth, the present invention provides for'pla'cing the counters in inverted position upon a support, with the upper edges of their bodies resting thereon and their flanges uppermost and immersing the support in the adhesive sufliciently to cover a portion of the counter-bo'dies, the flanges remaining above the adhesive. In another aspect, considered with particular reference toapplying an ad- 'improved methodis illustrated in the achesive to nested counters, the method of the present invention, as herein exemplified, consists in placing upon a support a series of nested counters arranged in frictional engagement with each other so that they retain their relative positions as a unit and immersing the support with the series of counters in'the adhesive. The nested coun ters are preferably drawn out until the rear portions are separated from one another, and predetermined portions of the entire series are dipped simultaneously in the adhesive as a unit. I

The counters C are commonly suppliedto shoe-manufacturers packed in nestedqseries, as appears in Fig. 1, the body-portions 10 being placed successively one within another and the flanges12 being similarly superposed. These are placed in close relation, to occupy as little room as possible, the rear portions of each counter being in close proximity to those adjacent to it, and the sides contacting 'over practically their enthe surfaces. In carrying out the present method, the o 'rator takes such a series, of suitable lengtl i and draws it out, as is represented in Fig. 2, the body-portions now being separated, so that contact exists only points of the-next counter. The series, however, still maintains its unitary character because of the frictional engagement of the units thereof With each other, with the result that it may be grasped by the operator and lifted as a whole, without separation and that this-series relation will be main- I tained during the coating operation. In

, rod and overhanging the receptacle is a: bracket 22, to which the grid 14 is secured...

this relation, a suitable number of the separated series are placed side by side, with their flanges uppermost, upon a support, which may be furnished by the grid l tof a coating apparatus A. This apparatus,

which may be'of any suitable type, is illustrated as consisting of a receptacle 16 for the adhesive which is to be employed, the receptacle having extending from its opposite extremities vertically perforated lugs 18, 18, within which mayweciprocate rods 20, 20. Fixed upon the upper end of each The grid may be of any desired form which W111 offer a suitable support for'the series of counters and permit free passage of the paste or other adhesive contained in the re-' ceptacle through the grid .into contact with the counters. It is held normally elevated, so thatthe supported objects are above the contents of the tank, by springs 24, 24 sur-' rounding the rods 20 and interposed between portions of the frame indicated at 26 and a bar 28 fixed to the rods. Pivoted at 30 upon lugs depending from the underside of the receptacle is an actuating lever 32 lying above the bar and having a handle at the front of the apparatus. By a depression of the lever, the rods 20, 20may' be lowered against the expansive force of the springs,.carrying the grid below the surface of thepa-ste, and thus immersing in such paste the supported counters. The dimensions of the grid 'are' preferably such that a plurality of the series of counters may be carriedside by side. Three of the series are so shown in Fig.v 3 of the drawing.

The depth of the paste is suflicient to at least cause the immersion of the counters to the desired level at some point short 01' the flanges when the lever 32 has been fully depressed, the limitv of movement inthe apparatus illustrated bein determined by the contact of the grid with the bottom of the.

' receptacle. If desired, the paste may be pletely covered, save for a narrow area adjacent to the flange, while said flange receives none of the paste. The counters may the counters-desired, an to the drawn out now be utilized one by one from the series until all have been applied to shoe-uppers. In doing this, each counter as taken from the gridmay be grasped by its .unpasted portion, so the operators hands do not come in cohtact with the paste, and the smearing of this upon theupper is avoided. When the supply of pasted counters has been ex- ,hausted, the coating operation may be repeated, the time necessary to operate upon a relatively large number being very brief. It will be seen that the coating operation of our method involves less labor 'for many counters than for a single counter when brush-coated, and that the only preparation necessary for this is the extending of the 'nested series. Moreover, the coating is unirecise portionsof these only, and the operator need not bring his hands into contact with the pasteupon the counters or upon the apparatus.

Having thus described our invention, what we claim as new and desire to'secure Letters Patent of the United States is 2-- 1.

2. The method of applying an adhesive to nestedconnters, which consists in placing upon a support aseries of the nested counters arranged in frictional engagement with each other so that they retain their relative positions as afunit', and immersing the support with the series of counters in the adhesive.
