This rebound is 1n someinstances sufiicient to cause a second impression to be made. i
A mechanism is provided in the present application to prevent the hammer from striking the actuator and thereby prevent this rebound, and will now be described. A. rod is carried by two arms 76 loosely mounted on the beitore mentioned shaft 46. One end of a link 77 is pivoted to one of the arms 76, and itsother end is pivoted to an arm 78 which loosely mounted on a shaft 79, carried by the frames 37. The arm 78 has a slot 80 cut therein, into which extends a stud 81. mounted on an arm 82 pivoted on the shaft 36. A spring 85 provided to keep the slot 80 in proper relation with the stud 8. This spring 85 is wound around the shaft 46, and one end engages one of the arms 76, and the other end engages thebase 71. The arm 82 is providedwith two shoulders 83, between which the yoke member 50 is adapted to lit, as shown in Fig. 2.
. When the yoke 50 is rocked by the cam 60, it will rock the arm 82, and through the stud 81 will rock arm 78. The first movement of the yoke will rock the arms 76. through the link 77, in a countcr-cloclnvise direction. and. thereby rock the rod 75 from beneath all of the hammers 34.
When the high points (it! of the cam (50 pass the outer end of the arm 59 oi the bell crank 58, and the spring LT rapidly rotates the yoke 50 and the actuator in a counterclockwise direction as above described. the arm :82 will return the rod; 75 to theposition shown in Fig. The rod 75 will reach its home position when the yoke 50 stomped hy the lug 70. At this time the hammer is travelling by its own momentum to take the impression. hen the hammer returns to its home position the rod 75 will. be in position to be engaged by the hamme' and prevent it from engaging the actuator 35, thereby preventing the hammer from rebounding against the type carriers andtaking a second \Vhile the form. of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to beunderstood that it not intended to conline the inventionto the one term of embodiment herein disclosed, "for it is susceptible oil embodiment in various forms all coming within the scope ol' the clailnswhich follow. Y
.What claimed is:
1.. The combination of a plurality of impression hammers, type carriers, :1 spring mtuated means for ('lriving each of the hammers against the type carriers :lfor taking an impression therefrom, and. a single means for arresting all of the hammers after the impression has been taken to prevent allot said hammers from engaging the spring actuated means. i a
2. The combination of a plurality of impression hanjnners, a springactuated means for driving each of said hammers against the type carriers for taking an in'ipression therefrom, and a single means for arresting the hammers after the im n'ession has been taken to render said spring actuated means inefi'ective. y i
3. Thecombination of plurality of impression hammers, type carriers, a spring driven actuator for each hammer, a single driving means for positively driving said actuators in one direction, and a single means interposed between said hammersaml said actuators when in the home position, said interposed means being disengaged from the hammers by the driving means when the driving meansbegins to ope ate.
4:. The combination of an impression hammer, type carriers, spring-actuated means for driving the hammer against the type carrier for taking an impression therefrom, and means for arresting the hammer after the impression has beentaken to prevent said .hammer from engaging the springeactuated means.
5. The eombinati on of an impression hammer, type carriers,spring-actuated means for driving said hammeragainst the type carriers :tor takingan in'ipression theiet'rom, and means tor arr am n-1e hammera tter the i npression has been. taken torender the spring-actuated means ineffective.
6. The combinationot an in'ipression hammer, an actuator therefor, said hanilner be ing resilient l y connected, to the actuatorwhen being actuated herehy, aspiring tor driving said actuator. means {or stoppihg said actuator, and means controlled independently of said actuator for. preventing tliehannner from engaging the actuator when the h anlmer returns to itshome position.
T. The combination oi an impression hammer, a spring driven actuator therefor, a spring-tor engaging the hammer with the actuator when the actuatoris being driven pr or to actuatingthe hammer for taking an impression and means independent of said Ell) tor for each of said hammers,' a springtor engaging each hammer with its actuator when'the actuators are being driven prior to pression has been taken.
