,WITNESSES: INVENTOR l l/v'ZZiam Efierimm a %W/%M9 inoperative position and will permit delivery of a matrix from its respective channel. Such means consists in the present instance of a cam which in the form shown embodies a sleeve 16 provided with alternately or reversely positioned cam projections 17 and 18, these projections being spaced in alter-' nate relation'with respect to the circumference of the cam. The cam is pinned or otherwise keyed to an actuating shaft 19, this shaft being mounted in suitable bearings 20 onthe upper side of the magazine and a ratchet wheel 21 is fixed to the shaft, this ratchet wheel having teeth 22 which correspend in number to the number of cam projections, and these ratchet teeth are spaced in predetermined frelation to the cam projections,

An actuating arm 23 is turnably mounted on the shaft 19 and it carries a springpressed pawl 24: which, when the actuating arm is turned in one, direction, ,will engage,

a tooth on theratchet wheel 21 and rotate the latter one step, the cam being correspondingly rotated whereby one of the ma trix retaining fingers will be moved by its respective cam projection into position to engage the foremost matrix in its corresponding channclto prevent delivery of such matrix while the other retainii'ig pawl will from the escapement pawl 7 so that this escapement pawl will reingage' the shoulder 25 with certainty after a matrix has been delivered from the other channel.

The actuating arm 23 for the reversing cam is, according to the present invention, actuated at appropriate intervals from the line delivery carriage 26 when the line carriage begins to deliver the composed line of matrices and spacers, the line carriage being provided for this purpose with an.

operating projection 27 to cooperate with a latch 28, the latter being turnable on a stationary pivot 29 and it has an operating shoulder 30 "to coiiperate with an operating arm 31, the latter being also mounted to turn on the pivot 29, and the shoulder 30 is yieldably held in engagement with the arm 31 by a tension spring 32. A link 33 is pivotally connected to the arm 31, and the upper end of this linlt is operatively connectcd to a lever 3a, the latter beingturn able on a stationary pivot 35 and it has a slot 36 which operatively engages a pin or projection 37 on the ratchet-actuatingarm 23. A spring 38 returns the link 33 and the connected parts to normal position after each actuation thereof by the line carriage,

lt'ach delivery movement of the line carriage 26 toward the left in Fig. 2 causes the projection 27 thereon to engage the latch- ,28 and turn the latter about its pivot 29, the

shoulder 30 on the latch bearing on the arm 31 and causing the latter to be turned also about the pivot 29. In this manner, the bar 33 moves downwardly and the slotted end.

of the lever moves upwardly carrying with. it the pin or projection 37 on the actuating arm 23 and thereby causing the ratchet wheel 21 to rotate one step, and owing to the operative relation between the cam and the ratchet wheel, one of the. retainingpawls will permit delivery of a matrix from one magazine channel, and the other retaining pawl will prevent delivery of a matrix from its respective channel.

During the movement of the line carriage,

the operating projection 27 thereon will trip past the latch 28 owing to the arcuate path of movement of the lower end of this latch, and when the line carriage returns to initial position or moves toward the right in Fig. 2, the operating projection 27 will trip past the latch, as illustrated diagrammatically by the dotted lines in this figure, this trip ping action being permitted owing to the pivotal relation between the latch and the arm 31 and the yielding of the spring 32 which connects such parts. It is therefore obviousthat a suflicient supply of matrices is provided for by the plural number of magazine channels, and that the matrices are delivered uniformly from the different channels owing to the alternate action of the matrix retaining pawls. It is to be understood that the shaft 1-9 can be extended and provided with additional cams and retaining pawls in order that matrices may be deare livered alternately from additional double matrix channels of the magazine.

It is advantageous to govern the delivery of matrices from the different magazine channels from the line delivery carriage as the latter operates to reverse thematrix delivery mechanism so as to draw the matrices from the alternate channels immediately after each line hasbeen composed and while such line is being delivered, a supply of the desired matrices being thereby insured at the commencement of the composition of each line. 7 1 r I claim as my invention 1. In a machine of the linotype class, the combination \vitha magazine having a plurality of matrix containing channels, es-

'capement means operative to cause delivery of matrices from such channels, and a re ciprocatory line delivery carriage, of means for causing delivery of matrices alternately from dillerent magazine channels embodying a member located in the path of movement of the line delivery carria e and operative by said carriage during the line delivery movement thereof,

2, In a machine of the linotype class, the combination with a magazine having a plurality of matrix containing channels, escapement means operative to deliver matrices from such channels, and a reciprocatory line delivery carriage, of means for causing delivery of matrices alternately from dili'erent magazine channels embodying a pivoted lever arranged in the path of movement of the line delivery carriage and actuated by said carriage when the latter moves in one direction and permitting reverse reciprocation of said carriage without producing operative movement of said lever.

3. In a machine of the linotype class, the combination with a magazine having a plurality oi? matrix containing channels, escapement means operative to cause delivery of matrices from said channels, and a reciprocatory line delivery carriage carrying an actuating projection, of means for causing delivery of matricesalternately from said channels embodying a lever pivoted on a fixed axis relatively to said carriage and having a portion arranged in the path of the actuating projection on the carriage, said projection actuating said lever and disengaging therefronrdnrmg movement of the line delivery carriage in one direction.

4. In a machine of the linotype class, the combination with a magazine having a plurality of matrix containing channels, escapement means operative to deliver matrices from said channels, and a reciprocatory line delivery carriage having an actuating projection movable therewith, of means for causing delivery of matrices alternately from said, magazine channels embodying" a lever pivoted on a fixed axis and operative in one direction by said projection and ans: toniatically disengaging therefrom when the" line delivery carriage moves in one direction and movable idly in a reverse direction by said projection during a reverse movement of the'line delivery carriage.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses.
