CARL MUEHLEISEN, 0F BERLIN, 'GERMANY, ASSIGNOR TO MERGENTHALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

LINE-CASTING MACHINE.

To all whom it may concern:

Be it known that I, CARL M'UnnLnIsnN, a citizen of the United States of America, residing at 88 Chausseestrasse, Berlin, N. a, in the-Empire of Germany, have invented new and useful Improvements in Line- Casting Machines, of which the following is a specification.

The present invention consists of improvements in the line-casting machines described in the specification of Letters Patent No. 436,532.

The accompanying figure is a side elevation of the preferred constructional form of this invention.

73 is the cam shaft; 74, a cam fast on it; 76, a bell-crank cam lever; 77, the first elevator, whose function is to receive the composed line of matrices 78 and lower them to the mold, the said elevator rising after the casting operation in order to deliver the composed line to the distributor. The parts 73, 77 and 78 are as in the above-named patent, in which, however, the weight of the elevator 77 rested upon a spring contained within a vertical tube carried by the front end of the cam lever 76. According to the present invention, the first elevator 77 is suspended from the cam lever 7 6 by a stud 80 projecting from the said elevator; a link 81 having a vertical slot 82 in its upper end and in which the stud 80 engages, and having a similar slot 83 in its lower end and in which engages a stud 84 fast on the front end of the cam lever 76. The spring 85 is connected at its upper end with the upper end of link 81 and at its lower end with the lower end of the elevator frame, and is under such tension that the elevator frame will normally be sustained by the spring and drawn up with the pin 80 in the upper end of the slot 82.

86 is a set screw extending downwardly through the lower end of the link 81 and into the upper end of the slot 83 in position to be engaged by the stud 84, by which means the amount of play or lost motion between the arm 76 and the link 81 may be varied.

When repeat type bars are to be cast from the same composed line, the elevator 77 must not be raised as high toward the distributer after a cast when that line is in two faces as when it is in a single face; for

if it were, the variant face matrices (which stand higher in the composed line than those of the normal face) would be depressed to the level of the latter by contact with the well known depressor as the elevator was attaining the highest point in its rise. The selection of height to which the elevator 77 may rise, is made by a detent which is moved into the path of the rising elevator if the line is in two faces, and kept out of that path if the line is in a single face. Both the operation of casting repeat type bars and the construction and arrangement of the detent are well known in the art and therefore do not require further description. Now the rise of the lever 7 6 and, therefore, that of the link 81 is constant.

When the detent is adjusted in the path of the rising elevator so as to arrest the same, the cam lever 76 will be permitted to complete its full stroke, the slot 82 in the link 81 permitting the link to move upwardly relative to the arrested elevator, and the spring yielding in this relative motion. When however, the detent is adjusted free of the path of the rising elevator so that the same will be permit-ted to move to its full extent, the complete stroke of the cam lever will result in the positive rise of link 81 as before, and this motion will be transmitted to the elevator through the medium of the spring 85, which suspends the eleyatlor and carries the same along with the in z.

Having described my invention I declare that what I claim and desire to secure by Letters Patent is 1. In a line casting machine, the combination of an actuating lever, a rising and falling elevator, a link connected with the lever and having a limited sliding connection with the elevator, and a tension spring connected with the link and with the elevator and acting by its pull to yieldingly suspend the elevator; whereby if the ascent of the elevator is arrested, the link will be permitted by the stretch of the spring to continue its motion relative to the elevator.

2. In a line casting machine, the combination of an actuating lever, a rising and falling elevator, a link connected with the lever and having a limited sliding connection with the elevator, and a tension spring connected withthe link and connected also with the elevator at a point below the connection of the link with the elevator.

3. In a line casting machine, the com bination of an actuating lever,,a link mov' able with the lever and also relatively thereto, a rising and falling elevator movable with said link and also relatively thereto, and a spring cooperating with the elevator and link to yieldingly support the elevator on the link.

4. In a line casting machine, the com-' which the link is adapted to move upwardly to a limited extent, and a spring cooperating with the link and elevator to: yieldingly resist their movements relative to each other.

.5. In a line casting machine, the combination of an actuating lever movable up and down, a link correspondingly movable I with the lever and in relation to which link the lever is adapted to move downwardly to a limited extent, an elevator movable up and down with the link and in relation to 1 which the link is adapted to move upwardly to a limited extent, and a yieldingconnection between the link and elevator.

In witness whereof I have hereunto set my hand in the presence of two witnesses.v
