Abstract: 28,284. Pearson, M. H., Jerram, A. E., and British United Shoe Machinery Co. Dec. 23. Riveting; blanks, supplying. -Apparatus for feeding. headed rivets in riveting- machines is described as applied to eyeleting-machines. The eyelets are placed in the inclined cylinder A, Figs. 2 and 3, the floor of which consists of the disc C rotated by the worm gearing C<3>, C<5>, or by other suitable means, and mounted on the central ball pivot C<8>, which is adjusted by the pin C<7> and locked by the nut C<9>. The disc C', of vulcanized fibre or other suitable material, is placed in a recess in the disc C, leaving an outer ring C' of metal. The eyelets are brought by the rotation of the disc against an aperture in the wall A, adjusted by the slide A<1> to such a height that only those eyelets standing on their flanges or ends, or in the reverse position, can pass through. The slide A' is adjusted by the screw A<3> in the bracket A<4> and is clamped by the screw A<35>. The guiderail A<5>, extending circumferentially behind the aperture, has an undercut part A<6>, engaging the flanges of the eyelets, and conducts the eyelets to the tangential guide formed by the rails A<5>, A<7>. The rails are thickened at the part A<38> so that the inverted eyelets, such as D<1>, are conveyed by the upper surfaces of the rails and are delivered into the pocket A<10>, while the correctly-positioned eyelets D are conveyed by means of the undercut part A<6> to the shoot D<2> of the eyeleting-machine. The pocket A<10> is attached to the pivoted arm A‹, connected by a chain A<12>, or a rod, to some intermittently-moving part of the machine, or to a treadle, which, when actuated, causes the arm A<9> to rise, and the pocket A<10> to deliver the eyelets through the opening A<11> into the cylinder A. The arm A<9> may be arranged to operate every time fresh work is inserted in the machine. The spring detent A<30> retains the eyelets on the rails A<5>, A' when the pocket A<1> is not in its normal position. Figs. 4 and 7 show a modification of the invention applicable to the eyeleting-machine described in Specification No. 22,461, A.D. 1903, [Abridgment Class Fastenings, Dress]. The disc C is horizontal and is coned at the central part C'‹. It is rotated by means of the toothed ring C<13>, pinion C<14>, and bevel gearing C<16>, C<17> from the main shaft E'. The slide A' is adjusted by the pin A<14> on which is rotatably mounted the milled bead A<15>, having an eccentric boss A<16>, eccentrically carried in the disc A<17>, rotating in the projection A<18> of the wall A. When adjusted, the side A<1> is clamped by the nut A<19>. Index marks may be formed on the milled head A<15> or on the part A<18>. The part of the rail A<5> behind the aperture in the container A is formed as a separate piece A<20>, pivoted at A<31>, and held in its normal position by the spring plunger A<21>, engaging the projection A<32>. The position of the rail A<20> is adjusted by the screw A<22>, the end of which engages the slide A'. The slide A<24> enables the container A to be rapidly emptied. It is operated and locked by the screw A<33> engaging a vertical slot in the part A<36> of the wall A. The discharged eyelets fall into a receptacle placed below the opening A<37>. The arm A‹ carrying the pocket A<10> is held between friction plates on the end of the spindle A<26> connected by links A<27>, A<28> to a treadle. By this arrangement, the spindle A<26> may be revolved through a greater angle than that communicated to the arm A<9>, the movement of which is limited by a stop.
