I, II and V) between which‘ there extends a horizontal shaft 29. The shaft 29 extends through the arms 28 and supports a 4 but it is permitted to return only until stopped by engagement of the washer 48 with the lower end of the sleeve 45. The segment gear 35 is in mesh with a pinion substantially U shaped frame 36 which extends 52 which is rotatably mounted on a shaft 53 31 which surrounds the shaft 29.‘ The opposite end of the spring 3'! is engaged with a pin 38 ex tending from a collar 39_which is ?xedly secured ing impetus of the spring 3'!) rotates the shaft extending parallel to the shaft 29 through the backwardly and upwardly from the shaft 29 and arms of the fr me 30 near its rear end. A ratchet which is ?xedly held in place by means of a wheel 54 (sefalso Fig. IV) is’integral with the brace 3| riveted to it and secured to the bracket pinion 52 and is engaged by a pair of spring 21. A rocker arm 32 is pivotally mounted on the shaft 29 near one of its ends. One end of 10 held pawls 55 which are mounted on a collar 56 ' pinned to the shaft 53. The downward stroke of the rocker arm 32 consists of a ?nger 33 which the segment'gear 35 rotates the pinion 52 and is engageable by a roller 34 mounted on one end ratchet wheel 54 without turning the shaft 53 of the cross head 24. The opposite end of the since the pawls 55 merely snap past the teeth of rocker arm 52 is shape-d into a segment gear 35. A pin 35 (Fig. II) is riveted to the rocker arm 15 the ratchet wheel 54. However, the upward stroke of the segment gear 35 (under the return 32 and is engaged by one end of a spiral spring 53 in a counterclockwise direction (Figs. I and IV). This also rotates a knurled feeding wheel . to the shaft 29. The spiral spring 31 is wound 20 5? which is pinned on the shaft 53 and an escape ment Wheel 58 which is pinned to the end of the in the proper direction to turn the rocker arm 32 shaft 53 opposite from the pinion 52. The escape in a clockwise direction (Fig. 1). One end of ment wheel 58 (Figs. II, VII and VIII) is located the shaft 23 extends through a castellated 001- v in the interior of an escapement housing 59 iar 40 (Fig. II) which is located outside the frame 35 and engaged by a pin 4| extending trans 25 which is mounted on the end of the shaft 53 versely through the shaft 29. At the opposite end of the shaft 23 are located a cotter pin 42, which extends transversely through the shaft 29, and a turning pin 43 which also extends trans versely through the shaft 29. In order to increase or decrease the tension of the spring 37 on the rocker arm 32, the cotter pin 42 is removed and the shaft 29 moved longitudinally a sufficient dis tance to disengage the pin 4! from the slot in the castellated collar 4%. The shaft 29 is then 35 rotated, by means of the pin 43, in the proper direction to increase or decrease the tension of the spring 31, the pin 4! once more engaged in a slot of the collar 45 and the cotter pin 42 re inserted. . A stroke limiting rod 44 (Figs. I andIII) is piv-v otally connected. to the lower end of the seg ment gear 35 and extends downwardly through the hollow interior of a vertically extending threaded sleeve 45. The lower end of the rod 44 carries a washer 4B which engages with the lower shoulders of the sleeve 45. The exterior of the sleeve 45 is threaded and screwed into a horizon tally extending ear 41 of the bracket 21. ‘Four longitudinal serrations 48 are cut in the outer surface of the sleeve 45 and are engageable by a ‘manually movable latch 49 which is pivoted by means of a pin 55 extending through the ear 41. A wire spring 5! extends through the lower end of the pin 50 and into a hole bored in the ear 41. To adjust the length of stroke of the rocker arm 32 and the segment gear 35, which is a and prevented from turning by engagement be tween its outer wall and the frame member 30. An escapement pawl 65 is rockably mounted on a pin 5i and has two pointed arms 62 which are alternately engageable with the teeth of the es capement wheel 58. A counterweight 63 is at tached to the escapement pawl 6%! to cause it to rock with a pendulum-like motion. The es capement mechanism just described serves as a governor to prevent the return movement of the segment gear 35 under impetus of the spring 31 from being abrupt or sudden. The knurled feeding wheel 51 extends down into a longitudinal opening in the upper wall of a hollow paper guide. 84 which leads from a posi tion in back of, and below, thev feeding wheel 51 to a position between the opposing faces of the abutment l4 and platen frame !5. The periphery of the feeding Wheel 51 is engaged with the up per surface of a ticket strip 65 which extends through the ticket guide 54. A duplicate ticket strip 65 also extends through the ticket guide 64 beneath the ticket strip 55. . A pressure roller 61 (Figs. V and V1) is rotat ably mounted on a pin 68 which is threaded through one arm of a bell crank 69 pivotally mounted in a backwardly extending arm 70 of the bracket 21. A spring ‘H (Fig. V) extends between the other arm of the bell crank 59 and an ad justable spring hook 12 mounted on the arm 10 of the bracket 21. The peripheral portion of the pressure roller 6'! extends through a slot 54’ in the lower wall of the ticket guide 64 and portion thereof, the latch 49 is swung, against is engaged with the undersurface of the dupli the action of the spring 5!, out of engagement with the serrations 48. The sleeve 45 is then 60 cate ticket strip 65. Pressurev exerted by the spring ‘H forces the pressure roller 6‘! toward the rotated to move it up which permits the rocker feeding wheel 51 and this pressure feeds the two arm 32 to be swung in a clockwise direction (Fig. ticket strips 55 and 66. ' I) by the action of the spring 31 or down which The upper end of the feeding guide 54 (Figs. moves the arm 32 downwardly against the ac tion of the spring 31 by the engagement of the 65 IX and X) has square shoulders and a bellied center portion. When the ticket strips 55 and 55 washer 46 with‘ the end of the sleeve 45. Since are initially inserted in the mechanism, the du the roller 34, which is connected to the cross plicate ticket strip 65 is out with a centered spear head 24 and which engages the ?nger 33 of the point end. When this duplicate ticket strip rocker arm 32, moves through a ?xed distance for each‘ energization of the solenoid, the ad 70 reaches the bellied upper end of the guide 64, because of the fact that the guide takes a ‘sharp justment of the sleeve 45 just described varies turn upward into the space between the abutment the lost motion distance between the roller 34 l4 and platen frame it, the sharp spear point on and the ?nger 33. Thus, regardless of the ad the entering end of the duplicate ticket strip 66 justment of the sleeve 45, the segment gear 35 is'always swung downwardly to the same point 75 adheres to the wall of the guide 64 havingfthe 5 2,407,522 greater curvature and thus is led in behind the inked ribbon 26 (as shown in Fig. X). The en tering end of the ticket strip 65 is cut on the diagonal with the point thus created being at one side of the strip. Therefore, when this diagonally pointed end of the ticket strip reaches 6 of the spring 3'! and rotates the pinion 52. How ever, due to the ratchet mechanism shown in ' Fig. IV, the shaft 53 is not rotated. After the type impression has been made, the electrical circuit to the solenoid is opened and spring means (no-t shown) retracts the solenoid the upper end of the guide 64 the leading por core rod 23. This moves the roller 34 down tion of the strip is between the square shouldered wardly out of the way of the ?nger 33 of the portion of the guide 64 and the strip 65 is not rocker arm 32 and the tension of the spring 31 permitted to follow the duplicate strip 66 but is 10 swings the rocker arm and the segment gear 35 swung forwardly in front of the ribbon 26. in a clockwise direction (Fig. I). This rotates Two ‘curved exit guides ‘I3 and 74 are formed the shaft 53 and the feeding wheel 51 and, de in that portion of the mechanism cover which is pending upon the total length of the stroke of the located above the space between the abutment segment gear 35 as adjusted by the sleeve 45, I4 and platen I‘! in line with the upper end of the 15 feeds the ticket strips 65 and 66 a certain distance ticket guide 64.
