Abstract: 1960. Boult, A. J., [United Shoe Machinery Co.]. Jan. 27. Lacing-fastenings; eyeleting. - The machine is primarily intended for inserting the right and left hand hooks described in Specification No. 12,891, A.D. 1900, into the uppers of boots, but parts of the invention are applicable to eyeleting-machines generally. The right and left hand hooks C, Fig. 8, are contained, respectively, in hoppers D, each of which has a shoot E leading to the dies H, L. Reciprocating vertically in an opening in the bottom of each hopper is a plate G, to which the plate F is pivoted by the pin 7<a>. The plate F has a tongue along its upper edge, engaging the hooks between the flange 3 and the hook part 4. The tongue is normally held horizontal by the spring 7<1>, but, when the plate rises, it is tilted by the projection 7 and the hooks pass into the shoot E, being supported and guided in the correct position by the upper edges of the plate G. Hooks which fail to pass into the shoot fall on the inclined part d<4> of the hopper. The plates G are connected by the rod g and link g<1> to the lever g<3>, which is reciprocated by the cam g<2>, operated by means of gear wheels g<4>, g<5> from the main shaft B. Fig. 6<a> shows the section of the shoot E, which, at its lower end, is cut away, so that the hook is supported by the groove 8 and a groove in the plate 72, and is held in position by a hook on the spring- pressed plate 70 until taken by the die. The die L moves to one side, and rises to receive the hook, which is pressed into position by the finger 74 as the die returns. The top of the die is shaped to receive the hook, the flange 3 resting on the top part and the hook part 4 lying in the groove l<1>. The working face of the upper stationary die is shown in Fig. 11. The cutting-edges h split the tubular stem 2 of the hook, and the projection h<1> spreads the split ends and presses them into the boot upper. The die L is secured to the arm l', which is mounted on the shaft N, and is reciprocated vertically by the cam P on the shaft B engaging the plunger M, the spring n acting to depress the parts. Fig. 12, which is a horizontal section along the line 12 of Fig. 1, shows the means for moving the die horizontally. The camgroove 10 in the collar R on the shaft B engages the pin 11 on the yoke S, one of the arms of which is held in engagement with one of the projections 16 on the collar 17 secured to the shaft N. The yoke S is turned, to cause the other arm to engage the other projection 16, and the die L, to co-operate with the opposite shoot E, by means of the link 13 connected to the lever 14, the end of which engages the socket 22 fixed on the shaft 21, which is turned by the lever 20, attached to a treadle. The lever 20 has arms 23 engaging arms 24 on the pivoted member 25, a segment 27 of which brings the clutch W on the shaft B into engagement with the clutch 28 on the power shaft to start the machine. The spring 29 normally holds the clutch members out of engagement. The upper is fed between the dies by the table K, to which is given a step-by-step forward movement corresponding to the number and spacing of the hooks. The table slides on the fixed arm 30. The collar 32 on the shaft B has an inclined rib 33, engaging successively the teeth on the rack 34 on the carriage 35, which slides on the base 36. The pawl 38 on the arm 39 pivoted to the carriage 35 engages teeth on a rack on the frame A, and prevents backward movement of the carriage. The shaft 50 has an arm 52 engaging the end of the table K, and an arm 51 which is slotted and engages a sliding block locked in place on the carriage 35 by the screw 53. By altering the distance between the block and the shaft 50, the distance moved by the table K at each step may be varied. The collar 41 on the shaft B has a tooth 40, Fig. 17, which engages the lug 42 brought into its path by the motion of the carriage 35, and, depressing the arm 39 against the spring 43, frees the pawl 38 from its rack, allowing the spring 37 to return the carriage 35 and the table K to their initial positions. The spring 72<1> on the collar 41 has lugs engaging notches in a groove in the shaft B, by means of which the position of the collar can be adjusted to trip the arm 39, after any desired number of feeding-movements corresponding to the number of hooks inserted in one side of the upper during the forward motion of the table K. The arm 39, on being depressed by the lug 40 at the end of the travel of the table K, engages a projection on the shaft 61, and turns the shaft against the action of the spring 66, bringing the inclined lug 64 in the path of the lug 65. The engagement of the lugs separates the clutch members W, 28, and stops the machine. Means are provided for throwing the mechanism out of operation after any feeding-movement. The projection 14<a> on the lever 14 engages either the inside or the outside of a segmental flange on the collar R, and, in either position, holds the clutch members together and the yoke S in engagement with one of the projections 16. If, when the opening in the segmental flange comes opposite to the projection 14<a>, the lever 20 has been released by the operator, the lever 14 is free to move, and the spring 29 separates the clutch members.
