LINO'IYPE-MACHINE.

certain new and usefulIm'provements in Linotype-Machines, of which. the following is a. specification.

- My invention relates to improvements in linotype machines, and more particularly to band which will not wear the thin intermediate portion of the band, but will support the'same upon its thicker edge portions, and at the same time prevent any lat-- eral movement of the s pace'bands.v

This applicatio'nfis a division of my application filed August 17 1910', for linotype machines, and given Serial No. 577,640. g

The invention consists in certain novel features ofronstructmn, and comblnations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims. v

- In the accompanying drawings: Figure 1, is a view in front elevation illustrating the assembling mechanism of anordinary linotype niaehinewith my improvements 1n position. Fig. 2, is \a. top plan view of the mechanism shown in full lines in Fig. '1.

' ing bar,' and Fig. 5, is a-perspective view referred to.

tween toothed rack 11 is formed on the upper edge showingan ordinary space band.

Referring particularly to Fig. '1, a per tion of the frame 1, the elevator 2, and the star wheel 3 of an ordinary linotype machine are illustrated in dotted lines, and my improvements illustrated in full lines in their cooperative relation to the parts above 4, is, the assembler slidewhich is made with aslot 5 through which a guide block 11 projects and is adapted to guide the sliding movement-0f the assembler slide, and 7 is a spring bar for drawing the slide longitudinally. -to its starting point with its adjustable finger 8 against star Wheel 3. This assembler slide-is moved in the opposite di rection as the matrices 9, and spacebands 1O are assembled and moved into position bet'he star wheel andfinger 8. A

a gear Wheel 12 which is fixed' to turn with a dial-15, and. both have rotary mounting in a plate 14-. The said dial 15 is 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 to twenty-nine, dividing the dial into thirty marks indicating p'icas.

, A bracket 39 is adjust-ably secured to the frameof the machine by means of a screw 40, and on this bracket 39 my improved spaeeband supporting bar 4L1, is pivotally connected by a 'pin 42,. said bar being normally held in horizontal position by means of an ar1n43 on bracket 39, which limits its downward pivotal movement. This bar 41 in cross section, is of general inverted T- shape, that is, it. is provided with a central longitudinal flangeeti exteridiiig throughout its lengtlr. I

The sp'aoebands in machines of this character are notched at their lower ends, and these notches are in the thin intermediate 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.-

portions of'the band. Bars to support these bands have been; provided on' machines of "With my improved bar 41, the bands are supported on their thicker ends on the horizontal portions of the inverted T-shaped bar, and the flange ii, while it projects up into the I notches of the bands, does not bear against thethinner metal of the bands, and does notwear thesame, yet; it prevents laterallmovement of the bands. This'bar 41 projects through the elevator, and is pivoted slightly-by the movement of the elevator as.

the latter carries the assembled line up 'wardly.

The bracket 39 above referred to is rendered adjustable vertically by forming a slot 45 in the bracket to receive screw 40. This vertical adjustment is desirable because i tl1e supporting ears on the upper endsof spacebands as ordinarily made should wear, the I bar &1 may be adjusted vertically so as to compensate for this wear, and insure a proper operation of the spacebands asv they move through the machine.

Various slight changes might be made in thegeneral form and arrangement of parts described without-departingjronr-my invenupwardly projecting flange or member of tion, and hence I do not limit myself to the precise details set -forth,'but consider myself at liberty to make such changes and altera tions as fairly fall within the spirit and scopeof the appended claims. I

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

1. In combination with a linotype machine, and space bands having notches in their lower ends, a space band supporting bar of inverted T-shape in cross section, the

said bar of appreciably less height than the depth of the notches in the space bands, whereby the space bands are supported at their ends only on the surface of said bar at the sides of said flange, substantially as described.

2. In combination with a linot pe machlne,

and space bands therein having relatively thick outer portions and relatively thin inner portions notched in their lower ends, a bracket fixed to the machine, a bar bar of general inverted T-shape in cross sec tion, providing a central guiding flange projecting into the notches in the space bands, said: flange of an appreciably less height than the depth of the notches in the-space bands, and supportsat both sides of said flange for the thicker outside portions of said space bands-at their base, substantially as described.

'In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
