ASSEMBLING MECHANISM FOR TYPOGRAPHICAL LINECASTING MACHINES Filed May 22, 1951 Patented May 31, 1932 UNITED STATES PATENT OFFICE CHRISTIAN AUGUSTUS ALBRECHT, OF BERLIN, GERMANY, ASSIGNOR TO MERGEN- THALER LINOTYPE COMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK ASSEMBLING MECHANISM FOR TYP OGRALPHIGAL LINE-CASTING MACHINES Application filed May 22, 1931, Serial No. 539,262, and in Germany June 2, 1930.

In typographical line-casting machines, such as those known commercially under the trade mark Linotype, it has frequently been found necessary to use magazines of greater width than those of standard machines, for the purpose, for example, of accommodating therein thicker matrices. As the height from which the matrices fall from the outlet or discharging end of the magazine to the'entrance of the assembler, had to be maintained unaltered, the widening of the magazine resulted in a reduction of the angle to the horizontal of the assembler-belt which conveys the matrices towards the assembler, and as a consequence of this disturbance of the belt, in combination with the great momentum of the thick matrices, the latter were projected in the direction of the assembler belt, past the assembler entrance, so that those matrices were not properly engaged by the star wheel. 8

Various attempts have been made to'overcome this difficulty, for instance, the matrix assembling guides have been bent more sharply, and also, particularly at the place where the matrices aredefiected from the assembler belt, resiliently mounted andso adjusted that the matrices reach the front of the star wheel correctly, the said spring guides beingoperative to deflect the successive matrices correctly. It has indeed been possible, with the means heretofore proposed, to avoid, in the main, the jumping of the matrices, out of their path, but the matrices were frequently damaged by the extremities of the springs; these means also left a great deal to be desired so far as concerned the noise involved in the impact, and in the timing of the -de-.

by the provision of a blade spring extending between two studs,'at the place where'the matrices are deflected downwardly out of the plane of the assembler belt, said spring being bent more or less by the matrices, according to their weight, and thereby constituting a deflecting guide for the matrices, to effect tween'the spring h, and said rails. be observed that the matrices m traversed by an efficient directional diversion of the matrices without noise and without interrupt.-

ing their progress. V

The accompanying Figures 1 and 2, illustrate, in diagrammaticalform, and in a front elevation, two constructional forms of the invention; a a

In both figures, a is the ordinaryassembler front, through which thedescending matrices pass from the magazine, to reach the endless assembler belt I). The assembler belt, at its lower end travels around a pulley 0, adjacent to which are the matrix guide rails d, between which the star wheel 6 rotates. The star wheel delivers the descending matrices to the assembling: line of matrices 7". Above the guide railsd is located the usual chute spring 9. According to the invention, a special'spring is provided. In

Figure 1, this spring h, is pivotally'supported at its upper end, by a pm 8', so as to be easily turned on the latter, whilst the lower end is bent into a loop or hook, to engage a pin is. The distance between the pin k, and the guide rails d is such that even the thickest matrix will comfortably slide down be- It will the assembler belt I), (one of which has been drawn in full lines in Figure 1, and in dot- .ted lines in two more advanced positions) come into contact with the spring h, when leaving the belt b. The spring thus becomes bent in the manner indicated by the dot-anddash lines inFigure 1,and assumes such a tive matrices, so that the latter will be properly delivered to thefront -ofthe star wheel.

The chute spring 9 prevents the overturning of the matrices when r they leave the spring h. In Figure 1, the matrix is shown once more in full lines, in the position it 00- cupies when: it'is about to leave the spring 7b.

The second constructional form illustrated in Figure 2 diifers from the previously described one, simply by the fact that the lower end of the spring, here bearing the ref! erence letter a, is free. A descending matrix first rocks said spring about its pivot i to the position in which it is shown by the dotted form as to constitute'a guide for the respec- I r en line, in which it bears against the stud k, and

thereafter bends it to some such form as that indicated by the dot-and-dash line.

Gbviously quite a number of other constructional forms could be devised; For example, the spring could be pivoted at its lower end on the stud is, and have its top end bearing freely against the inner side of the stud i.

In the construction according to FigureQ, the spring a must obviously be sufficiently light to yield under the impact of even the thinnest matrix, so as to give the latter a free passage.

Having described my invention, ll declare that what I claim and desire to secure by Letters Patent is 1. Assembling mechanism fortypographical line-casting machines with a spring abutment arranged at the end or the path followed by the matrices when leaving the assembler belt, characterized by the fact that the spring extends between two studs so that said sprlng is bent between the studs under the wei ht oi the matrices ro'ected a ainst it. 7 a

2. Assembling mechanism according to claim 1, characterized by the fact that the spring is pivotally supported at both ends and can easily be turned about the pivots.

3. Assembling mechanism according to claim 1, characterized by the fact that the spring is pivoted at its upperend, and adapted at its lower end to enga e an abutment or stud located in the path or that en d to limit its movement.

4. in assembling mechanism for a typora hical line-castin machine the combination with an'inclined assembler belt and a chute spring 111 the path of matrices leaving the belt, of a spring abutment intermediate the belt and chute spring and studs pivotally supporting the spring abutment at its ends beyond the part which it is first struck by the descending matrices.

5. In assembling mechanism for a typographical line-casting machine, the combination with an inclined assembler belt and a chutespring in the path of matrices leaving tie belt, of a spring abutment intermediate the belt and chute spring, a stud from which the spring abutment is i'reely'suspended at its upper end and a' stud located in the path tollowed by its lower end when swung about the first named stud under the vi eightof a descending matrix.

In testimony whereof I have affixed my ignature hereto,

CHRISTIAN AUGUSTUS
