LINOTYEE-MACHINE.

Specification of letters Patent.

Patented Mec. 117, 1912.

To all ww'm 'it may concern:

Be it lmown that I, VViLLIAiiLM. RAP?, a' citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Linotype-Machines, of which the vfollowing is a speoiication.

-My invention relates to improvements in linotype machines, and is more particularly designed as an improvement upon the construction disclosed in Patent No. 932,577 granted to me August 31, 1909, the object of the invention being to provide an improved gage operated by the assembler slide through the medium of improved mechanism recording the length of the line of' matrices as it is assembled.

A further object is to provide an improved construction of this character which may be attached to the ordinary linotype machines in use, being readily substituted for the old constructions on the machines.

With these and other objects in view, the

invention consists in certain novel featuresv of construction and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims,

In the accompanying drawings: Figure 1, is a front elevation illustrating the assembling mechanism of an ordinary linotype machine with my improvements in position. Fig. 2, is a top plan view of the mechanism shown in full lines in Fig.. 1. Fig, 3, is an enlarged view in elevation of the indicator operating mechanism with the dial removed. Fig. 4, is an enlarged end elevation. Fig. 5, is a/view of the opposite end of the mechanism, and Figs. 6, 7, 8,.'9, andv 10 are views ,of various details ot construction.

Referring particularly to Fig. 1, a portion of the iframe 1, the elevator 2, andthe star wheel 3 of an ordinary linotype machine are .sections providing longitudinal slots 5 through which guide blocks 6 project to guide the sliding movement of the assembler slide, and 7 is a sprmg bar for drawing the slide longitudinally to its starting point with its adjustable finger 8 against the star wheel 3. This assembler slide is moved inv the opposite direction as the matrices 9 and spacebands 10 are assembled and moved into position between the star wheel and linger 8.] A toothed rack 11 is formed on the upper edge of the slide 4, and meshes with the teeth of a'fgear wheel 12, iixed to a shaft 13 having rotary mounting in the plate 14. On this shaft 13, a dial 15 is secured and spaced from the gear by means of a block or sleeve 16, and this dial is provided with a scale around its periphery, beginning with zero and numbered up t0 twenty-nine, dividing the dial into thirty marks indicating icas.

p Onthe plate 14, a curved strip 17 is fixed, is concentric with the dial 15, and is provided with a scale having 'twelve indicating marks dividing the same into points, the dial and the strip 17 constituting a Vernier gage, and the coperating scales thereon indicate at all times the exact measurement ot the line assembled.

On the front' of the dial 15, a pointer 18 i is supported on a turn button 19, and this pointer indicates tothe operator when he is approaching the length of line desired.`

the path of?y movement of a beveled trip 2 4 which is vpivotally supported on a screw 25 which projects through the slot 5 in theassembler slide 4, and through an elongated slot 26 in a catch 27. This tripy 24 is pivotally mounted as above explained, so thatit will operate the dapper-20 when the slide moves to the lett, but will pivot .when the slide moves in the other direction, and not operate the clapper. The movement of the trip is limited 1n one direction by a pin 24a as clearly shown inl Figs. 3 and 4. This"l `catch 27 is provided'at its upper edge with teeth 28 to engage in the teeth of rackl 11, and engage the gear 12 to prevent any further movement of the assembler slide. A forwardly projecting tongue 29 is provided at the lower end of the catch 27, and a coiled spring 30 is positioned between this tongue 29 and a block 31, which is recessed to accommodate the slide 4, and through which the screw above referred to projects, trip 24 being located at one side of the block in front of the slide, and catch 27 located at the opposite side of the block in rear of the slide. The trip therefore serves to sound v the alarm just ybefore the catch reaches the slide, and by pressing the tongue 29 up gear ,and stops further movement of the ward, the teeth 28 may be released from the rack 11 so that the trip may be located at any desired position on the assembler slide in accordance with the length of line to be set up. l

' Tovbrake the assembler slide, I employ a brake lever 33 which is pivotally supported between its ends on a screw pivot 34. One end of this lever 33 is bent upwardly and laterally as illustrated in Fig. 8, and pro-A jects into a bifurcated bracket 35, the two members' of this bracket 35 having recesses 36 to receive the lower longitudinal member of the assembler slide to straddle the same. The opposite walls of these recesses 36 are beveled as shown, so that when the bracket is in a vertical position, its sharp edges engage the slide and hold it against retrograde movement, but when the lever 33 is pivoted so as to tilt bracket 35 slightly, the latter presents a wider surface to the slide and allows it to move rearwardly. The long end of this lever 33 is made with `a bifurcated bracket 37, and a lever 38 is fu'lcrumed between its ends on the screw pivot 34, and at one end is located in the bifurcated bracket cated in the path of movement of the elevator 2, so that when the elevator moves upwardly to carry the assembled line of matrices, it will engage this lever 38 and the latter will move the bracket lever 33 so as to release the assembler slide and allow it to be drawn backward by means of the spring 7. This brake 33 may also be operated by hand or foot power whenever desired, and is held 1n normal positionby a spring 45.

A bracket 39 is fixed to the frame of the machme by means of a screw 40, and on this bracket 39 my improved spaceband supportmg bar 41 is pivotally connected by a pin 42, said bar being normally held in horizontal position by means of an arm 43 on bracket 39, which limits its downward pivotal movement. This-bar 41 in cross section, is of general inverted ll"-shape, that is, it is provi ed with a central longitudinal flange 44 extendin` throughout its length.

The space ands in machines of this character are notched at their lower ends, and these notches are in the thin vintermediate portions of the band. Bars to support these bands have been provided 'on machines of this character, but such bars engage the thin intermediate portion of the bands, and soon wear the same, resulting in damage to the bands and shortening their lives. YVith my improved bar 41, the bands are supported' on their thicker ends, and the flange 44, while it projects up into the notches of the bands, does not bear against the thinner metal of the bands, and does not vwear the same, yet it prevents lateral movement of .the bands. This bar 41 projects through the elevator, and is rocked on its pivot slightly by the movement of the elevator as the latter carries the assembled line upwardly.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination with the assembler slide of a linotype machine, of rack teeth on the assembler slide, a vernier gage comprising a fixed scale, and a rotary dial having a scale per, substantially as described.

2.

a pivoted trip adjustably mounted on the slide and constructed to operate said clapper, substantially as described.

3. In combinationwith the assembler slide of a linotype machine, of rack teeth on theI assembler slide, a vernier gagel comprising a fixed scale,v and a rotary dial having a scale thereon to register with the fixed scale, a gear wheel fixed to turn with the rotary dial of the Vernier gage, said gear, directly in mesh with the rack teeth, a pivoted clapper back of and hid by said dial, means on the slide to engage and operate the clapper to strike the dial, said means comprising a pivoted I trip adjustable on the slide, and name to this specification in the presence of means forming a part of Jshe trip support two subscribing Witnesses. adapted tio be engaged by the gear and limit the turning movement of the gear, as Well WILLIAM M' RAPP' 5 as the longitudinal movement of the slide, Vftnesses:
