Abstract: 146,882. Fanslow, B. O. June 3, 1918, [Convention date]. Index type-wheel machines ; letter-spacing mechanism.-In type-wheel machines for filling in cheques, the cheque, after each impression, is fed the length of a word plus a space by means of a reciprocating device which engages the cheque directly and is associated with variable stopmechanism. In the machine shown, the typewheel 9 bearing word-printing types 10 of different length is secured to a shaft 11 mounted in a plunger 12 which is depressed for impression by a hand-lever 17, Fig. 1, and is raised by springs 19. The hand-lever rocks a shaft 15 provided with cams 14 engaging rollers 18 on the plunger. The type-wheel is set by turning a knob 84, Fig. 1, the setting being indicated by a pointer 13 and a dial 4 on the casing 3. The shaft 11 is provided with a pinion 80, Fig. 3, driven by a pinion 79 which gears with a pinion 81 on the knob-spindle and is secured to a shaft 78 mounted in a boss 70 on the casing. The types are inked by rollers 90, Fig. 1, mounted on the plunger. The feeding-device comprises a feed-dog 54 and a detent 61, mounted on a slide 50 and a stationary guide 53 respectively. The feed-dog and detent are formed at the bottom with sharp prongs 55, 67 which register with grooves in a plate 68 in the base 1, the cheque 7 being gripped firmly by being pressed into the grooves. The feed-dog is pivoted on a pin 56 on the slide and is urged towards the cheque by a spring 57, a stop 60 limiting the movement. The detent, is pivoted on a pin 63 on the guide 53 and is associated with a spring 65 and a stop 66. The slide is formed with ears 51 for engaging the top of the guide, and is formed also with flanges 52 for engaging a flange on the bottom of the guide. The slide is operated and controlled by the following devices. Sleeves 29, 27, 34, Fig. 5, loosely mounted on a shaft 24, are provided with arms 30, 23, 39 respectively, the arm 30 having a forked end 48 engaging a pin 49 on the slide, and the arm 23 engaging a notch 21, Fig. 7, in the plunger 12. The arm 39 co-operates with a rotatable stopmember 71 which is secured to the shaft 78 and is formed with radial stop-projections 72 of graded heights, corresponding to the length of the associated types 10. A spring 36, connected to the sleeve 34, normally holds the arm 39 in engagement with a shoulder 69, Fig. 3, on the boss 70. The sleeve 29 is provided with a spring blade 31 in the path of the arm 23 and is provided also with a coupling-pin 28 which is urged outwards by a spring 45 and is adapted to engage a slot 25 in the arm 23. The sleeve 27 is provided with a coupling-pin 26 which registers with the slot 25 and is adapted to engage a radial groove 35 in the sleeve 34. Upon depression of the plunger 12, the arm 23 moves idly until it engages the spring 31, and the arm then retracts the slide 50, the feed-dog trailing over the cheque, and the detent holding the cheque. When the plunger is approaching the bottom of its stroke, the slide is arrested by the casing, and the arm 23 makes a short idle movement during which the spring 31 yields. During the idle movement, the spring 45 pushes the pin 48 into the slot 25, and the pin 28 pushes the pin 26 into the groove 35. Upon releasing the hand-lever 17, the plunger is raised by the springs 19, and the arm 23 moves idly until the bottom of the slot 25 engages the pin 28, the idle movement allowing the type-wheel to rise a short distance before the cheque is fed. In the further upwards movement of the plunger, the pins 28, 26 couple the sleeves 29, 34 to the sleeve 27, and the arm 30 advances the slide 50, the feeddog then feeding the cheque. The feed movement continues until the arm 39 is arrested by the stopprojection 72 that is in position, the height of the stop determining the feed movement. The pin 26 is then forced out of the groove 35 and returns the pin 28 to the normal position, thereby disconnecting the sleeve 27 from the sleeves 29, 34 and permitting the sleeves 27, 34 to be returned to the normal position. The stop-member 71 is looked in the set position bv a dog 74, Fig. 5, which is moved into and out of engagement with teeth 73 by a pin 77 on the plunger. Alining for impression.-A lever 42, pivoted on the plunger 12 and connected to an arm 40 on the shaft 24, is moved into engagement with internal grooves in the type-wheel when the plunger is depressed.
