GEORGE A. BATES, OF BROOKLYN, NEW YORK, ASSIGNOR TO MERGEN- THALER LINOTYPE COMPANY, A CORPORATION OF NEW YORK.

LINOTYPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 722,353, dated March 10, 1903.

Application filed January 8, 1908. Serial No. 138,264. (No model.)

ing one at a time from the magazine in front of a star-wheel are forced horizontally thereby into a channeled assembler, the star-wheel pushing the line forward so that the incoming matrices may enter at the end of the same. There are used in this machine certain elongated expansible spacers, consisting of two oppositely-tapered wedges. These spacers are dropped into the line from above through essentially the same path as the matrices. The matrices approach the line with considerable velocity and are liable to become battered or mutilated by their impact against the bottom of the assembler.

The aim of my invention is to provide a yielding device or buffer which will serve to check the momentum of the matrices before they strike the assembler and which will at the same time permit the space-bands to en ter without interference.

To this end it consistsin a yielding buffer located between the star-wheel and the assembler and having its upper end of peculiar form, as hereinafter described, whereby it is adapted to check the matrices, but permit speedy passage of the spacers.

Figure 1 is a perspective view representing my device applied to the assembling devices of a Mergenthaler machine. Fig. 2 is a perspective view of the buffer detached. Figs. 3 and i are diagrams illustrating the manner in which the buffer acts on a space-band and a matrix, respectively.

Referring to the drawings, A represents an inclined belt or apron over which the matrices descend to inclined guiding-surfaces B, which direct them downward in front of a vertical star-shaped wheel 0, by which they are crowded forward horizontally into the end of the assembler.

E represents my buffer or resistant, consisting of a spring e, underlying the frame and fastened thereto at the rear end by a spring 6 or its equivalent, and of a block or resistant e fixed to the forward end of the spring, with its upper end standing below and in front of the star-wheel in the path of the incoming matrices and spacers.

The matrices, which are short and have flat lower ends, as usual, will strike upon the buffer, and being checked or retarded thereby are instantly pushed forward therefrom into the assembler. The spacers H (shown in Fig. 4) being of much greater length than the matrices and falling but a short distance at a lower velocity must not be retarded. I therefore cut away the sides of the resistant or bufier on inclined lines, as shown in the drawings, so that it presents a flat upper surface only at the middle. This remaining surface is sufficiently narrow to pass through the vertical notch in the lower ends of the spacebands. It follows, therefore, that when a space-band descends its lower end will straddle the center portion of the resistant and strike on the inclined surfaces at the sides, the result of which is to carry the end on the band instantly forward clear of the resistant,

so that the end of the band may continue its motion downward through the assembler without appreciable loss of time. The important feature of construction in this regard lies in so forming the buffer that it will arrest or check the matrices, which move with great velocity, but will not appreciably check the space-bands, which move at slower speed.

The operative end of the buffer may be made of any suitable material, and it maybe supported by a flat spring, as shown, or in any other appropriate manner.

Having described my invention, what I claim is 1. In the assembling mechanism of a linotype-machine, a bufier having a surface to check the motion of the incoming matrices and an inclined surface to deflect the spacers and prevent their retardation.

2. In a linotype-machine, an assembler arranged for delivering matrices and spacebands individually thereto, an intermediate yielding buffer having a surface at substantially right angles to the path of the matrices, to retard their advance, and an inclined surface to deflect the spacers and prevent their retardation.

3. lhe attachment for a linotype-machine, consisting of a retarding-piece provided with a surface to receive the impact of the matrices and an inclined surface to deflect the spacers.

4. In a linotype-machine and in combination with the fiat-ended matrices and the 10 spacers having notched ends, the bulfer or retarding device having surfaces in diiferent positions to receive the impact of the matrices and the spacers respectively.

In testimony whereof I hereunto set my hand, this 2d day of January, 1903, in the 15 presence of two attesting Witnesses.

GEORGE A. BATES. Witnesses:

J. N. BLANCK, HERMAN F. Voss.
