1 Claim.

The present invention relates to assembler slide bar stops and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

It is an object of the invention to provide a stop for the assembler slide of a Linotype machine which will be silent in its operation,

Another object of the invention is the provision of a device of this character which may be readily substituted for the present conventional metallic stop.

A further object of the invention is the provision of a device of the character set forth which will: be easily adjustable for Wear and the like.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:

Figure 1 is a fragmentary perspective view of an embodiment of the invention,

Figure 2 is a plan view of the essential portions of the invention.

Figure 3 is an elevational view, partly broken away, of Figure 2.

Figure 4 is a sectional view taken along line 1-4 of Figure 3,

Figure 5 is an end view of the device as shown in Figures 2 to 4, inclusive, and

Figure 6 is a rear elevational view of the device.

Generally, there is provided a stop for an assembler slide bar such as is conventional in Linotype machines. The stop may readily replace the conventional metallic stop now in use which has the disadvantage of wearing away due to the constant impact of the end of the assembler slide bar thereon. The present metallic stop also has the disadvantage of causing a great deal of noise. The applicant has provided a stop which may be readily interchanged with the conventional stop without the necessity of tapping 0r drilling the Linotype machine in any manner whatsoever. A framework is provided in which is adjustably mounted a rubber buffer which is adapted to take up the impact of the assembler slide bar thereon.

Referring now more particularly to the drawing, there is shown therein an assembler slide bar 10 which is conventional in character and which is adapted to be retracted to the normal position shown in Figure 1 by means of a spring contained in a housing I l and which is connected thereto by means of a tape l2.

It will be understood that in a Linotype machine the lines of type are assembled in an assembler by means of a revolving star wheel. The

2 lines of type are held in an assembling elevator and rest against the slide finger carried at one end of the assembler slide bar. After each line has been delivered to the elevator the assembler slide, including the finger, is returned to the position shown in Figure 1 of the drawing. It is important that the slide finger should never come into contact with the revolving star wheel. In order to prevent such an occurrence it is conventional to provide a metallic stop at the end of the assembler slide member opposite to that carrying the finger above mentioned. This conventional metallic stop is prone to wear under continued impact by the assembler slide bar, eventually allowing the slide bar to move farther than was originally calculated and thus allowing the finger to come into contact with the star wheel.

The present invention overcomes this objection by providing a stop member having a frame in which is adjustably mounted a buffer of rubber or the like which provides the advantages above set forth.

The stop forming the present invention comprises a hollow frame [3 provided with a pair of screws l4 for attachment to the body 15 of the Linotype machine in the conventional openings (not shown) provided for the old type metallic stop member. Within the hollow interior of the frame l3 there is mounted a closely fitting buffer I6 preferably formed of rubber which is adapted to protrude through one end of the frame in such manner as to receive the impact of the assembler slide bar when the same is returned to its normal or starting position. The end of the frame opposite to that through which the buffer l6 protrudes is closed, as indicated at IT, and has threaded therethrough an adjusting screw l8 which is provided with a head l9 adapted to contact the inner end of the buffer IS.

A look nut 20 is provided upon the outer side of the screw is for holding the same in selected 7 positions.

In operation, it will be apparent that the buffer I6 is adapted to replace the metallic stop member and to absorb noiselessly the impact of the assembler slide bar when it returns to its normal position. It will also be apparent that the buffer may be forced outwardly of the frame l3 when it has worn away or when it is desired to adjust its position for any other reason.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing 3 4 from the spirit of the invention or the scope of REFERENCES CITED the appended claim.
