Abstract: 12,883. Boult, A. J., [United Shoe Machinery Co.]. June 8. Eyeleting ; lacing - fastenings.-A machine for fixing eyelets in shoe uppers &c., of the type described in Specification No. 18,530, A.D. 1899, is provided with means for automatically suspending the presentation of eyelets while the machine continues to punch holes for the lacing- hooks. Fig. 1 is a side elevation of the machine, and Fig. 3 a partial plan viewed at an angle of 45‹. In presenting the work to the machine, the holders H are lifted by a treadle, and the sides of the upper are laid against the opposite sides of the guide-plate G, and their edges against a guide. The punches P advance and punch two holes in opposite sides of the upper against the anvil-plate A, and the feed-frame F then rises. The eyelet shoots C advance and present eyelets, which are set in the holes by the setting-tools S. The shoots C retire as the tools S advance. The tools 8 are first partially released, while the feed frame F is moved to feed the upper through the distance between successive eyelets. The tools S are then withdrawn, and the feed-frame returns, bringing the punches to their original positions. When it is desired to punch holes without setting eyelets, the paths of motion of the shoots C are changed, as shown in Fig. 3. The feed-cam lever is connected with the frame F by links 50, 51, to which is pivoted the link 112, connected to the pivoted arm 114, which moves over the quadrant plate 115. Stops 116 on the plate 115 limit the movement of the arm 114. The arm 114 is mounted on a shaft, which carries, at its lower end, the arm 118, connected by the chain 119 to a treadle, by depressing which the arm 114 is swung over the plate 115 to increase the amount of feed-motion and to move the quadrant plate. The spring 120 returns the arm 114, and the spring 121 restores the quadrant plate to its normal position against the stud 122, Fig. 1. The quadrant plate may be moved by the handle 123. The eyelet pot E, Figs. 1 and 5, is a cylindrical vessel, having a contracted waist forming inclined surfaces leading to the shoots C. To the sides are secured the combs 127, through which the eyelets are swept by brushes 128 into the shoots C. The combs are provided with pivoted cover-plates 129 secured by spring pins 130. The shaft 131, carrying the brushes 128, projects from the vessel E and is attached to a disc having three holes, arranged irregularly and adapted to engage projections on a disc mounted in bearings in the bracket 141 and oscillated by means of the crank 136 connected to the feed-cam lever. The eyelet pot has projections 143 engaging locking-members 142 on the bracket 141, from which they may be disconnected by turning the eyelet pot on its axis. The eyelet pot E and shoots C are oscillated by the lever 145, mounted on the pivot stud 146 and supported by eccentric projections 155. The base 144 is secured by bolts in the holes 147 to a lug on the lever 145. The adjusting-screw 150 in the lug engages a groove in the base 144. One end of the lever 145 is connected by the eccentric stud 151 to a roller engaging the cam 40 on the main shaft M ; the other end is secured to the shoots C by the bolt 154. The stud 151 provides an adjustment at rightangles to that given by the screw 150. In order to alter the path of motion of the shoots C and prevent them from presenting eyelets to the tools S, the eccentric supports 155 of the pivot 146 are turned by means of the segmental rack 160, engaging the pinion 158. The pawl 161, pivoted on the stud 151 on the lever 145, engages the tooth 162 on the arm 163 secured to the rack 160. The pawl 161 is normally pulled down by a spring connecting it to the rack 160, and only engages the tooth when it is raised by the rod 164, connected by the lever 170 and link 171 with the quadrant plate 115. After the rack 160 has been moved by the pawl 161, the spring pawl 165 drops into engagement with the shoulder 166 on the rack. When the rod 164 descends, the collar 167 strikes the pawl 165, releasing the rack and allowing a spring to return the shoots C to their former position. A device to prevent the throwing-out of the shoots at any other than a predetermined time consists of the detent 175 engaging the tooth 176 on the plate 115. The detent is pivoted on the stud 177 and is acted upon by the spring-pin 178. The arm 179 has a recess 180, which is opposite the collar 64 when the feed-frame F is in its lowest position. When the feed-frame rises, as shown in Fig. 3, the collar 64 engages the end 181 of the arm 179 and releases the detent 175 from the tooth 176. The operator prepares the machine for throwing the shoots C out of operation by depressing the treadle, which swings over the arm 114 and moves the plate 115, raising the rod 164 when the detent 175 has been released. At this time, however, the pawl 161 has moved too far to the left to engage the tooth 162, and the shoots C are not thrown out until the next revolution of the main shaft. A hand-operated device to prevent the throwing-out of the shoots consists of the latch lever 172 pivoted on the bracket 68. The lever is moved by a handle so as to lie between the edge of the plate 115 and the surface of the bracket 68. Features of the invention are applicable to machines for setting lacing-hooks.
