eerie HEINRICH DEGENER, OF BERLIN, GERMANY, ASSIGNOR TO MERGENIHALER LINO- TYPE COMPANY, A CORPORATION OF NEWEZORK.

TYPOGRAPHICAL LINE-CASTING MACHINE.

Specification of Letters Patent.

Patented (lot. 21, 1913.

Application filed June 10, 1911. Serial No. 632,427.

To all whom it may concern:

Be it known that I, HEINRIcII Dncnnnn, a subject of the German Emperor, residing at 26 Hollmannstrasse, Berlin, in the German Empire, have invented new and useful Improvements in Typographical Line-Casting Machines, of which the following is a specification.

The present invention relates to an improvement in typographical line casting machines of the Mergenthaler type, and in particular to that construction of such machines, in which, for readily effecting a change of magazine, the magazine frame, with the magazine thereon, is capable of being raised and lowered and when so raised, and not before, can be turned about a vertical axis through 90 degrees to enable the magazine to be removed over the side of the machine. The magazine, before the said turning movement, is capable of being moved forward and downward sufliciently to enable its upper end to clear the magazine entrance. It is, however, possible that the magazine might accidentally descend too far and injure the keyboard of the machine.

The present invention aims at preventing this last-named further descent of the magazine by providing a locking device which engages the magazine until by the aforesaid turning thereof, or by hand, the said device is released.

In the accompanying drawings which show, as an example, one constructional form of the invention, Figure 1 is a plan of the magazine with the magazine frame thereunder shown in dotted lines. Fig. 2 is a right-hand side View of part of the same; and Fig. 3 is part of a cross section on the line 3*?) of Fig. 1, on a somewhat enlarged scale.

The magazine 1 is guided on the magazine frame 2 by a rail 3 secured to the underside of the said magazine and free to slide longitudinally in a groove in the upper surface of the magazine frame 2. The rail 3 is attached to the cross ribs 4, 4, which are .attached directly to the underside of, and serve to strengthen, the magazine 1. According to the present invention a bar 5 with two recesses 6 is secured to the magazine 1, in

the space between the rail 3 and the said magazine, or the recesses 6 may be formed in the rail 3 itself. A bolt 7 is mounted on the magazine frame 2, which is constantly urged toward the left by a spring 8. In the normal or working position of the magazine, the bolt 7 is in engagement with the lower of the recesses 6. This lower recess is beveled on its upper side, so that when the magazine 1 is moved slightly forward preparatory to being changed, the bolt 7 is forced back and remains so until the upper of the recesses 6 is presented to it whereupon the spring 8 shoots the said bolt into that recess. The portion of the bar between the two recesses 6 canbe removed so as to form but a single long recess. The magazine 1 is, by these means, secured in position and cannot, for the time being, be slid any farther forward. The magazine 1 and magazine frame 2 can now be turned about the axis of the vertical pintle 9 toward the side of the machine, and at the end of this turning movement the bolt 7 can be withdrawn from engagement with the respective recess 6 either by hand or automatically by the following means :The bolt 7 is connected at its right-hand end with one arm of a twoarmed lever 10, which latter is pivoted at 11 to the magazine frame 2. On the bearing 12 within which the pintle 9 turns, or on some other part of the machine, is secured an abutment which cooperates with the free and downwardlybent arm of the lever 10, in such manner that during the before mentioned turning of the magazine 1 and magazine frame 2, it withdraws the bolt 7 from the respective recess 6, and thereby insures that only after the said turning movement is completed, can a complete release and removal of the magazine take place.

It will be understood that before the magazine and its frame are turned about the vertical pintle 9, they are preferably raised from their normal position in the manner described in my application Serial No. 556,441, filed April 19, 1910. The specific construction of such elevating means is however immaterial to my present invention.

It is to be understood that the before de scribed apparatus is provided with the usual devices for preventing the magazine frame 2 being turned until it and the magazine thereon have been raised to the desired extent.

laving described my invention, I declare that what I claim and desire to secure by Letters Patent is 1. In a typographical line-casting machine the combination with a magazine frame and a magazine mounted on the said frame with a capacity for removal therefrom in its normal plane, of a locking de vice which allows th magazine to move forward on the magazine frame, to a limited extent, and secures it in its normal plane against a further forward movement there on and removal therefrom until released;

2. In a typographical line casting machine the combination of a magazine frame, a magazine mounted on the said frame with a capacity for forward and backward movement th'ereon, the said frame together with the magazine bein capable, of being turned about a vertical axis, a locking device which allows the magazine to move forward on the magazine frame to a limited extent, and secures it against further forward movement thereon until released, and means effecting such release automatically during the aforesaid turning movement.

3. In a typographical line casting ma chine the combination of a magazine frame, a magazine mounted on the said frame with a capacity for forward and backward movement thereon, the said frametogether with the magazine being capable of being turned about a vertical axis, a bar secured to the magazine, a recess in the said bar, a locking bolt movable on the magazine frame, capable of engaging the recess, and a spring operative on the bolt to effect such engagement.

t. In a typographical line casting machine the combination of a magazine frame, a magazine mounted on the said frame with a capacity for forward and backward movement thereon, the said frame together with the magazine being capable of being turned about a vertical axis, a bar secured to the magazine, a recess in the said bar, a locl-: ing bolt movable on the magazine frame, capable of engaging the recess, a spring operative on the olt to effect such engagement, a lever operatively connected to the bolt, and an abutment with which the lever cooperates during the aforesaid turning of the magazine frame to disengage the bolt from the recess.

5. In a typographical line casting machine the combination of a magazine frame, a magazine mounted on the said frame with a capacity for forward and backward movement thereon, the said frame together with the magazine being capable of being turned about a vertical axis, a bar secured to the ma azine; two recesscs in the said bar, a locliing bolt movable on the magazine frame, normally engaging one of the recesses and capable of engaging each f them in turn, a spring operative on the bolt to effectsuch ei'igagcment, and means adapted to automatically disengage the bolt from the recess with which it normally engages, when the magazine slides on the magazine frame.
