Abstract: 23,810. Cade, B., and Heldrich, A. A. Oct. 27. Type-bar making machines; matrices; keyboards.-The matrices are carried by a series of rotatable sectors 5, Fig. 2, having radial laterally-flexible stems 8. The stems have at their outer ends heads 9, Fig. 21, in which slide the shanks 11 of the matrices 10. Each stem supports two matrices which may bear upper and lower case characters respectively and are movable independently or together. The matrices have apertures 128 at the upper ends of which are inclined surfaces 129 for alining the matrices. The sectors are enclosed in a housing comprising a fixed section 17 and a movable section 18, the two sections being separated at intervals to form an opening. through which the matrices can move to the mould 161. The sectors are rotated, in order to position the matrices, by springs 45 attached to sliding heads 42 which are connected by links 41 to arms 40 on the sectors. The sectors are held in, and are returned to normal position by a cam-actuated bar 33. The amount of rotation imparted to the sectors is determined by a series of sliding setting-bars 46, Fig. 3, which are adjusted by keys and are then interposed in the path of the heads 42. The setting-bars are urged to the right by springs 53 and are held against movement by racks and detents 71. The keys 76 operate a series of pivoted frames 77 of varying size, which, when raised, serve as stops for the setting-bars 46. The detents 71 are successively raised to release the bars 46 by a member 84, which is operated by the frames 77 and is moved step by step transversely of the series of detents by an escapement-mechanism. After the bars 46 have been adjusted for the whole line, they are raised into the path of the heads 42 and the matrix-sectors are thereby set. The composition of the next line can then be commenced. When matrices of more than one case are used, shift-keys are employed which act on the member supporting the frames 77. Clamping and alining matrices.-The matrices are alined by a bar 130, Fig. 19, which is moved by a rack-and-pinion through the holes 128 in the matrices and is then raised by elevating- members 132, 133 to carry the line against the mould 161. The line is held between jaws 162, 163, which are mounted on the bottom of the mould and are moved to and from each other by a right and left handed screw operated by a mutilated gear-wheel on the main shaft. Justifying matrices.-A spacer is carried by one of the stems of each sector and comprises a member 13, Figs. 3 and 23, having an inclined dovetailed groove in which a tapered member 14 slides at right-angles to the member 13. The spacers of the assembled line are adjusted by a cam-actuated bar 171, Fig. 2, which engages the members 14 and first contracts the spacers so that the line may pass between the jaws 162, 163 and then expands them to fill out the line. Driving-mechanism. - The main shaft 31, Fig. 2, carrying the cams which operate the parts of the machine is driven through a onerevolution clutch comprising a continuouslyrotating notched disk which is engaged by a spring bolt on the driven member. The bolt is withdrawn after one revolution by an incline and is released to start the machine by means of a hand-lever.
