1,228,361. Coating apparatus. BRITISH UNITED SHOE MACHINERY CO. Ltd. 16 April, 1968 [18 April, 1967], No. 17720/67. Addition to 1,182,774. Heading B2L. An adhesive-applying device comprises a chamber, a nozzle member comprising at least one outlet passage communicating with the chamber, an inlet tube extending into the chamber, means for feeding a metered quantity of adhesive through the inlet tube into the chamber, and means for supplying air under pressure to the chamber by a passageway other than through the adhesive inlet tube for expelling the metered quantity of adhesive through the nozzle member. A foot 18 is formed with a chamber 26 having outlets 32, and is secured to the lower end of a body 12 formed with a vertical bore 14 communicating with chamber 26. A pipe 20, supported co-axially in bore 14, projects into chamber 26 and communicates with the latter via a narrow bore 24 formed in a plug 22. Body 12 contains a heating element 28, and is formed with a lug 34 engaging a screw 38 mounted in a support 33 for varying the height of foot 18 for correct abutment with an insole I assembled with a shoe upper U on a lest L. A measured quantity of adhesive is first delivered to chamber 26 via pipe 20, and compressed air then admitted to bore 14 via an inlet 30 forces the adhesive out of chamber 26 through the outlets 32 into the space between the insole I and the upstanding margin M at the heel portion of the upper U. The foot may be made detachable. Adhesive is obtained from a heated reservoir via a compressed air-operated valve, the timed opening of which effects the metering of the adhesive.
