CHINERY CORPORATION, OF PATEBSONT, JERSEY, A CORPORATION F NEW JERSEY f roxrNef GEMENTING Application led January 11, 1928. Serial No. 246,028.

rlhis invention relates to machines for and methods of applying cement. In its machine y aspect,the invention is herein illustrated as' embodied in a machine for applying cementv to the foxing areas of tennis' shoes and the novel method provided 'by the invention is set forth with special reference to that cement-applying operation, although in variof the sides and ends of the upper of the shoe to hold'a thin strip of gum rubber known as the foxing. The overlappin edge of* the A*rubber sole is vulcanized to t e foxing when it isapplied to the shoe.v Heretofore.

the application of such a stripe of cement.

around the lower portion of the upper of a shoe hasgenerally been effected manually, the appli-cation being made by means of a brush held in one. of theioperators hands A while, with the other hand, the shoe is turned to present -its sides and ends to the brush. It requires considerable skill to apply the cement with sufficient accuracy sot at the upper edge of the cement stripe will -deine even approximately the desired line of demarcaton between the foxing area'and' the portions ofthe shoe upper Aabove the foxing area and this diiiculty is accentuated by the fact that the pay of the operators depends upon the amount of work they turn out,'so that the application of cement to the foxing areas is usually performed too rapidly for l the best results. If the upper edge of the stripe of cement is not well located, either some of the cement will show above the edge of the strip of foxing, disguring the shoe and very7 likely resulting Vin making it a second, or else, in places, the cement stripe will not extend high enough to hold the upper' edge of the foxing strip securely.

With the foregoing in mind, an object of the invention is to facilitate the application of cement to the foxing area of a shoe with the desired accuracy and at the same ltime to make it practicable to perform this operation `jeven more rapidly than' heretofore; To this end, I have provided an improved method in vaccordance with which the whole upper portion of a'shoe is rotected or shielded from the application o cement sprayed on the unprotected foxing area. Advantageously, the cement may be projected substantially simultaneously, as by spraying it, upon the whole of the-exposed foxing area of the shoe. As herein illustrated and described, a shield mounted in a fixed relation to spraying apparatus is employed and, upon movement of the v shoe relatively to the shield, the bottom portion of the shoe is projected through an opening in the shield to expose the foxing area to the application of cement. A

Another object of the invention is to pro, vide an improved machine for cementing the foxing areas of shoes, by means of which such cementing maybe done accurately while increasing the production and lowering the cost of the cementing.

In accordance with a feature of the invention in its machine aspect, the illustrated machine is provided with a shield constructed and arranged to protect the portions of the upper of a sloe which are not to becoated and comprising a plate having a peripheral portion adapted to be brou ht into juxtaposition to the shoeupper to degne the upper edge of the foxing area. y The illustrated shield has an;

opening shaped to correspond tothe peripheral shape ofthe bottom of a shoe through which opening a right-side-up shoe is inserted and projecting apparatus, illustrated as comprlsing spray openings, is provided surrounding this opening but below rthe shield sothat cement may be applied simultaneously to all sides of a foxing area exposedbeneath the shield. v

' Preferably, and as illustrated, the Aflow of cement is controlled by the opening and shut. ting of a valve e'ected by movement ofa work support as a shoe inserted in the openlng in the shield and placed on the sup ort is pressed downwardly to expose the oxing area below the shield and raised after the cement has been applied', the depth of insertion being controlled by adjustment of. the work support. Thus, it will be seen that it is only necessary for an operatorQ to iiisert a lasted shoe thrpugh the opening in the' ing description shield and push it into position to expose its foxmg area below the shield, whereupon cement will be applied simultaneously to the foxing area all around the shoe and will be limited to this area by the shield.

Still other features of the invention will appear from' a consideration of the followreference being had toI the accompanying drawings, in which Fig. 1 is a perspective view, partly in section, showing a shoe inserted in a machine embodying they invention and being coated with cement; i

Fig. 2 is a side elevation of a shoe showing theirelatiori of the edge of' the shield thereto; an

Fig. 3 is a transverse section through the machine.

My novel lmethod of applying cement may-l be carried out by means of the illustrated apparatus for coating the foxing areas of shoes in which apparatus protection for the portions of the shoe which are not to be coated is afforded by means of a shield 10 in the form of a relatively thin metal plate provided with an opening 12 which substantially corresponds in shape and size to the peripheral outline of the bottom of a shoeto .be coated but is large enough to permit passage of the shoe' bottom through it. It will be noted from an inspection of Fig. 2 that the shield 10 is curved heightwise to different levels with respect to the top of the shoe to correspond substantially to theFheightwise curvato require it.

ture of the desired line of demarcation between the foxing area and the upper part of the shoe, the foxing area band exposed beneath said shieldl when the shoe is inserted through the opening 12 therein being substantially uniform in width throughout. It will be understood that, preferably, a plurality of suchl shields will be provided, the openings of which vary in size and shape in accordance. with the sizes and shapes of differ-v ent shoes to be treated, and that these shields will be interchanged at intervals, as the differences in the sizes and shapes of various shoes presented to the machine are sutlicient The shield 10 is suitably secured to the top edge of a receptacle 14 which is provided with an annular passage 16 surrounding the receptacle. 1 This passage has an inwardly projecting lipv 18 provided with a plurality of perforations 2O orl spray openings through which cement lnay be projected in an even spray as at 22 and applied at the same time to the whole vertical extent of as well as to allparts of the foxing area 24 of a lasted shoe 26 presented thereto by the hand of the operator.

yAs the shoe, positioned right side up, 'is moved by the operator downwardly through the opening 12 of the shield, it contacts with a depressible work support comprising posts 30 which are secured to a common base plate 32and are normally held in elevated position by means of springs 34 surrounding each post. The posts 30 are guided in openings in the 'bottom of the receptacle 14 and pass through bosses 3.6 surrounding said openings. The movement of the plate 32 islimited by means of an adjustable stop-plate 40 having a horizontal upper surface 42 and aninclined lower surface which is resilintly held in coacting relation with the inclined surface of a wedge-shaped stop member l44 underlying said plate. Adjustment of the position of the upper surface 42 of the sto-p-plate40 is effected by means of a right and left screw 46 (Fig. 3) threaded in depending lugs 48 and 50 formed on the members 40 and 44. A re duced middle portion of the screw 46 is journalled in a lug 52 formed on the bottom of a casing 54 which is bolted to the under side of thev receptacle 14. Inasmuch as the screw j 46 cannot move laterally with 'respect to the lug 52, it will be seen that it is effective simultaneously to adjust stop members40 and 44, thereby to adjust the position of the upper surface 42 to determine the extent to which the shoe supports 30 may be depressed and, therefore, the extent of downward movement ofthe shoe. lBy means of the adjustment of the stop plate 40 just described, it is possible to determine accurately the position of the upper. edge of the foxing area 24 Qf the shoe relatively tothe shield 10 in order that the foxing area may be exposed below f the shield, it being only necessary for the operator to place a shoe within the opening 12 of the shield l0 and to push it down against the springs 34 of thework supports until the plate 32 joining said work supports contacts with the upper surface 42 of the stop plate 40. A supply of cement to be applied to the shoe is contained within a tank 60 which communicates with the annular passage 16v of` the receptacle 14 through a pipe 62. Pres,

sure is'applied to the contents of the tank gy a pump 72 joined to the tank by a pipe 7 4'.

as illustrated, a valve 64 is inserted in the pipe 62 so thatpressure may be applied to the passage 16' or interrupted. The arrangement i's such that the pump 72 is driven continuously. during the use of the machine so that the body of cement in the tank 60 vis under pressure ready to be projected through the `nozzle openings 20 of the'lip 18 when the valve 64 is opened by the insertion of a shoe through the shield. The operation of the projecting apparatus is controlled by the insertion of a shoemoved through the open ing in the shield to a. point where it occupies a fixed relation to .the shield and tol this end the peration of the valve 64 is made delever 66 piv the plate 32 joining .the work supports and its other end llinked to the valve 64. Thus the machine is automatic in its operation, depression of the work support as the shoe is pressed downwardly to expose its oxing area v below the shield being effective to turn on the supply of cement and'to cause it to be projected simultaneously against all sides of the shoe to form a stripe or band of cement coveringthe foxing area. When the shoe is removed, the springs 34"\lift the work supports and the control lever 66 shuts the valve 64.

Because of characteristics inherent in the shapes of shoes, -it will, be seen that the largest horizontalcross-.section of a typical shoe, anexampleof which is shown in F1g.

l, comes at or near the bottom thereof and that the corresponding cross-section ofthe shoe at the upper edge of the foxing area is smaller than that of the bottom edge. Hence the opening 12 of the shield ldoes not correspond exactly to the dimensions of the periphery of the shoe along the upper edge of the foxing area in view of the fact that the shoe is to be inserted through this opening from above. The direction of the spray is substantially parallel to the under side of the shield and hence is substantially normal to the surface of the foxing area. Accordingly, it will be seen that the shield and the cement applying means are relatively constructed and'arranged so that any portion of the spray which is directed toward a point' above the upper edge of the foxing area is deflected by the shield in a substantially hori- Yzontal direction.- This makes it possible to i apply a coating in which the upper edge of the cemented area l is sharply defined. It should be noted that it is immaterial whether lcement is applied to the bottom of the shoe during the operation of the coating of the foxin area because it is the practice .to coat the w ole bottom of the shoeafter the foxcementing operation has been completed. aving thus describedpmyinvention, what I claimv as new and desire to secure by Letters Patent of the United States is: l 1. The method of coating the foxing area of a shoe which consists' in shielding at one time all of the upper of the shoe which lies above the foxing area from the application of cement, and, keeplng the shielding relation constant, applying cement to a plurality of widely separated parts of the .foxing area f s imultaneouslywhile the shoe is so shielded.

2. The method of coating the foxing area of a shoe which 'consists in 'holdin the shoe upright, shielding from the application ofI cement that fractional part of the upper of the shoe which lies above the foxing area down to a foxing area different parts of the upper boundary of which lie at dilerent levels and spraying cement upon the exposed foxing area while maintaining ,unchangedv application of cement and, While the shield-r lng relation remains fixed, projecting a dispersed spray of cement to coat the whole of the foxi-ng area.

4. The method of coating the foxing area of a shoe which consists in simultaneously shielding all parts of the upper of the shoe above the foxing area, and the-n applying cement upon the whole of the foxing area at one time while the shoe is so shielded.

5. The method of coating the foxing area of a shoe which consists. in holding the shoe in upright position, moving the' shoe hei htwise of the shoe through the opening o an apertured shielding member to expose the foxing area beneath the lshielding member, holding the shoe in fixed relation to 4said shielding member,

and applying cement to a l plurality of parts of the foxlng area substanlevels with respect to the top of the shoe to prevent the application of cementA thereto whereby a foxing area of substantially uniform width is exposed near the bottom of theI shoe, maintaining this width during the coaty1ng operation, and applying cement to ,the

foxlng area upon opposite sides ofthe thus shielded shoe simultaneously.
