22,806. Badeau, L. C., and Badeau, I. F. Nov. 7. Typewriters.-In a typewriter for writing music, the types are carried by spring-controlled plungers mounted in a. disk A, printing being effected by depression of the plungers with the finger. The disk is rotated in order to bring the required type into the printing position, and is moved at rightangles to the line of writing to enable the sign to be printed in the desired position on the staff. This position i s determined by a stop bar which is actuated by keys b, consisting of spring-controlled tubes having at their lower ends inclined surfaces which engage with screws on an horizontally-pivoted stop bar g. The paper-carriage c is provided with wheels 3, running on rails 2, and carries rollers 4, 5, over which passes a leather or rubber band 6 on which rests the paper 7. Rollers 8, 9 cause the paper to travel with the band. The roller 4 can be rotated by means of a knob 12 on the axle 10, or by depression of either of two keys which actuate spur-wheels geared to the axle 10. The paper-carriage is moved parallel to the line of writing by a spring drum 14, mounted loose on a shaft 20 and connected by a band 13 to the carriage c, Fig. 1. The other end of the carriage is connected by a band 16, passing over a pulley 17, with a weaker spring drum 18 on the shaft 20. A toothed wheel on the shaft 20 is engaged by an escapement-lever 23 actuated by a key 24. The type-disk e is carried by a frame d, Fig. 2, which is supported bv rollers 27 so as to be movable at rightangles to the line of writing. A spring 58 draws the frame d to its outer or inoperative position. A disk 29, projecting from the frame d, carries a vertical post 30 on which is pivoted the type-disk e. Washers 38 are mounted on the post 30 and are connected by a coil spring 37. A projection on each washer rests in the path both of a pin 41 on the disk e and of a pin 40 on the disk 29. The disk e can thus be rotated either to the right or to the left, and will be returned to its normal position by the spring 37..The disk e is provided with sockets 31 in which slide tubular spring-controlled plungers 32 carrying at their lower ends types 34. Below the disk 29 and sliding in guides thereon is a slide 43 connected by a cord 46 to the frame d, and pulled to the right by a cord 47 connected to a spring. The slide 43 is provided with an aperture 45 through which the type-plungers can pass in order to print. In order to print a character, the finger is inserted in the cup-shaped recess formed in the top of the type-plunger 32, and the disk e is thereby rotated until the type comes over the vertical line in which the character is to be printed. During this motion, the plunger is depressed so that it rests on the disk 29, the type 34 entering one of a number of annular recesses formed in the disk. Each recess communicates with an aperture 42 in the disk 29, through which the plunger passes on to the slide 43. One of the keys b is then depressed and the stop g thereby adjusted. The frame d is then moved towards the operator so that the slide 43 comes into contact with the stop g and is arrested thereby. Further motion of the frame d brings the type-plunger over the aperture 45, through which it is depressed on to the paper. The type is inked by passing over inking-rollers 44.
