DISTRIBUTING MECHANISM OF TYPOGRAPHICAL COMPQSING-MACHINES.

Application filed March 27, 1916.

To aZZ whom it may concern Be it known that I, CARL HUnnLnisnn, a citizen of the United States of America, residing at Chausseestrasse 23, Berlin, Ni i, in the Empire of Germany, have invented new and useful Improvements in the Distributing Mechanism of Typographical Composing-Machines, of which the follow ing is a specification.

This invention relates to typographical composing machines such as those known commercially under the trade mark Linotype, and particularly to distributing mechanism therefor of the kind described in Letters Patent No. 1142222, which is used for separating matrices according to font in connection with machines having several magazines and employing matrices having font-distinguishing notches in their feet. The invention described in the above-mentioned patent, provides, in addition to the usual three distributer screws adapted to engage the two upper and one of the lower ears of each matrix while the latter is being propelled over the font-distinguishing bridges, a fourth distributor screw adapted to engage the second lower ear of each matrix, and gripped or mutilated. over those portions o it which coincide with the spaces between the bridges, by which means the matrices were maintained in correct position while traveling over, and allowed to drop freely between, the bridges. In the known constructional form of this arrangement, the fourth screw has been mounted in a pivoted frame capable of being rocked away to permit the interior of the font separator, namely, the distributor rail. the matrices suspended thereon and the bridges, to be inspected. In practice, however, inconvenience has arisen through the continued operation of the distributor when the fourth screw is so rocked out of its operative position, by reason of matrices falling away from the font separator, or getting out of proper position. g

According to the present invention, such inconvenience is avoided by providing means for stopping the operation of the font separator as soon as the fourth screw is rocked away.

The accompanying drawings illustrate a constructional form of the present invention as applied to the font separator of a ma- Patented Jan. 36), 1917.

chine provided with four magazines, Figure 1 being an elevation of the font separator as seen from the rear. of the m..- chine and with certain parts omitted; Fig. 2, a left-hand end elevation of Fig. 1, also with certain parts omitted, and Fig. 3, a plan of part of the separator-stopping;

means. 1

The frame 1 of the separator is of l znown construction, and carries the font-distinguishing bridges (not shown in the drawings), as well as the distributor screws, the lower mutilated screw 2 being arranged in bearings 8, which are pivotally connected at 4 to the frame 1. One screw of the font separator is driven by a shaft 5 which is geared with the other screws by means of pinions (3. The shaft 5 has a clutch ring 7 axially movable but angularly fast on it, with which ring a lever 8 engages. The lever 8 is connected by means of arod 9, with a lever 10 which rocks about a fixed pivot 11, and has a cam surface 12 (Fig. 3) abutting against a stop 13 fast to the adjacent bearing 3 of the screw The shaft 5 is also erovidcd with a loose pulley I i which is driven from the main driving shaft of the machine by a belt 15 and which can be coupled and uncol'lpled from the shaft 5 by the clutch ring '7.

When the screw 2 is in the operative position, as shown in Fig. 1 and in full lines in F 2, the stop 13 bears against the lever 10 and holds it in its leftmost position (Figs. 1 and thereby, through the rod 9 and lever S, maintaining the clutch ring '7 in engagement with the pulley 14, against the action of a spring 16 constantly tending to throw the clutch out, so that the shaft 5 is.

driven and the separator operates in the known manner. When, however, the screw 2 is rocked, by means of the handle 17 provided for that purpose, into the position shown in dotted lines in Fig. 2 in which the distributor rail 18 and interior 'of the font separator are open to inspection, the stop 13 is moved out of contact with the lever 10 thus permitting the spring 16, acting through the rod 9 and lever 8, to disconnect the clutch 7 from the pulley 14, whereby the separator is stopped. On the return of the screw 2 to its operative position the stop 13 glides over the cam surface 12 of the lever 10 and restores that lever to its leftmost position, throwing in the clutch and causing the normal operation of the separator to be resumed.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is 1. In a typographical composing machine, the combination with a distributer rail, four distributer screws adapted to propel matrices along the said rail, and drivin means adapted to rotate the said screws, 0 means whereby one only of the said screws can be moved out of its operative position, and means adapted to disconnect the driving means and screws when the said screw is so moved. 7

2. In a typographical composing machine, the combination with a distributer rail, four distributer screws adapted to propel matrices along the said rail, and driving means adapted to rotate the said screws, of means whereby one only of the said screws can be moved out of and into its operative position, and means adapted to disconnect and connect the driving means and screws when the said screw is moved respectively out of and into the said position.

3. In a typographical composing machine, the combination with a distributer rail, four distributer screws adapted to propel matrices along the said rail, and driving means adapted to rotate the said screws, of a pivot for the bearings of one of the said screws, the said bearings, and means adapted to disconnect and connect the driving means and screws when those bearings are rocked about the pivot to move the respective screw out of and into its operative position respectively.

4. In a typographical composing machine, the combination with a distributer rail, four distributer screws adapted to propel matrices along the said rail, and driving means adapted to rotate the said screws, of a clutch adapted to establish and disestablish driving connection between said driving means and screws, a pivot for the bearings of one of the said screws, the said bearings, and means adapted to open and close the clutch when those bearings are rocked about the pivot to move the respective screw out of and into its operative position respectively.

5. In a typographical composing machine, the combinationwith a distributer rail, four distributer screws adapted to propel mat rices along the said rail, and driving means adapted to rotate the said screws, of a clutch adapted to establish and disestablish driving connection between said driving means and screws, a pivot for the bearings of one of the said screws, the said bearings, and a spring constantly tending to open the clutch and adapted to be released when the said bearings are rocked about the pivot to move the respective screw out of its operative position.

6. In a typographical composing machine, the combination with a distributer rail, four distributer screws adapted to propel matrices along the said rail, and driving means adapted to rotate the said screws, of a clutch adapted to establish and disestablish driving connection between said driving means and screws, a pivot for the bearings of one of the said screws, the said bearings, a spring constantly tending to open the clutch, and a lever adapted to close the clutch against the action of the said spring when the said bearings are rocked about the pivot to move the respective screw into its operative posi tion.

7 In a typographical composing machine, the combination with a distributer rail, four distributer screws adapted to propel matrices along the said rail, and driving means adapted to rotate the said screws, of a clutch adapted to establish and disestablish driving connection between said driving means and screws, a pivot for the bearings of one of the flopiel of this patent may be obtained for five cents each, by addressing the "Commissioner of Patents.
