Abstract: 5367. Wade, H., [Miller Treeing Machine Co., O. A.]. March 3. Treeing and ironing.-A machine for forming creases in the vamp of a boot behind the toe comprises co-operating grooved dies 2, 4, and means for moving the die 2 over the other die on which the boot or shoe is supported. The die 4 is adjustably mounted on a horn 6, which carries a plunger 8 sliding freely in the machine frame 10. The horn is also guided in its movement by a rod 12 depending from the machine frame and passing through a rear extension of the horn. The die 4 is yieldingly lifted into engagement with the die 2 by depressing a treadle 28, which is connected by a chain passing over a pulley 26 and a spring 22 with a second treadle lever 20 connected through a link 18 and a lever 16 with the horn. A spring 29 normally tends to hold the dies apart. The die 2 is adjustably fixed to the forward end of a shaft 30 rotatably supported in the hub of a segment gear 32 and in a disk 34. Both the members 32, 34 are mounted to rotate freely on a stationary shaft 36 mounted in the machine frame. The shaft 30 has fixed to it a pair of gearwheels 40, which mesh with wheels 42 fast on the shaft 36, the four wheels being of the same diameter. The segment gear 32 is oscillated about the axis of the shaft 36 by a segment gear 44 on a lever 46 fulcrumed on the machine frame and slotted at its lower end to engage a stud 52 eccentrically mounted in a toothed disk driven from a motor 60. The degree of eccentricity of the stud 52 and so the swing of the die 2 can be varied by turning a disk 74 eccentrically mounted in the toothed disk and carrying the stud 52. The radius of the curved surface of the die 2 is made smaller than the radius of the curved surface of the die 4, so that the die 2 has a rubbing as well as a rolling movement over the surface of the work supported on the die 4. The dies are preferably heated by electricity. One lead from a heating-element in the die 4 is connected to the terminal at one side of a lamp 123 in an electric circuit, and the other lead is connected to a rheostat 132. The lead wires from a heating-element in the shaft 30 for heating the die 2 pass down the shaft and are connected to slip-rings 84, 86, which are supplied with current by two pairs of contacts 88, 92 projecting from rings 90 and 94 respectively. These rings are free to rotate upon the shaft 36, and are supplied with current by two contact-rods 96, 98 supported on blocks 100, 102. A spring 107 tends to turn the blocks to press the rods against the rings, but when it is desired that the die 2 shall not be heated, the blocks may be clamped in a position in which the rods 96, 98 are lifted from the rings. The terminals on the blocks are connected to the rheostat and the lamp terminal respectively, the other terminal of the rheostat being connected to the second terminal of the lamp, so that the heating-elements for the dies 2, 4 are in parallel with each other but in series with the rheostat. Other leads from the lamp terminals convey current to the motor 60. Steam, gas, or other heating medium may be employed instead of electricity.
