To allee/710m it may concern: y K

Be it known` that I, JAMES F. HoXsEY, a citizen of the United States, residing at lVashlington, in the District of Columbia, have invented new and useful Improvements in Adjustable Liners, of which the following is a specification.

The object of my invention is to improve upon that general type of device represented in the patent to Howard, No. 796,213, August 1, 1905, for use in molds of the type employed in the familiar Mergenthaler linotype, where a base element adapted to belixed at one side of the mold and, an adjustable one engaging therewith are employed. ,A

It is an important object to permit the size of the stationary or constant element to be reduced materially without limiting the range of adjustment of the device, thus permitting the casting of a much longer slug with a constant element of a given range of adjustability with relation tothe adjustable element, than in present devices.

A further important purpose is to so construct the two elements for coengagement that the adjustable member will always be l body, and for a suitable distance from the free to swing outwardly on the constant member, thus avoiding liability of breakage when the operator makes the `common mistake of leaving too large an ejector blade in the machine after adjusting the device to cast a shorter line.

It is ,also an aim'to construct the device so that under normal operation, after adjustmentand the first cast, the parts are held in rigid relation, sothat the adjustment will not be disturbed under proper use of the casting machine.

It is a further attainment of the invention that the parts of .the liner are formed to yinterlock with the filling oftype metal for the establishment -of their rigid relation, yet in such a way that when the device is removed from the' m'old the filling will fall from place, without the necessity of any special tools and without 'liability of serious sticking, as hasbeen found to occurin` practice with previous devices.

' Additional objects and advantages will be apparent from the followin descriptionor otherwise, and from the drawings, in which?- Figurc 1 represents a .familiar formA of mold base and cap plate detached with my invention in operative position therebetween after use, FigfQ is atop-view 'of4 the constant member of my device, Fig. 3 is a bottom ,view thereof, Fig. llis a top view of the spacer member, Fig. 5 is abottom view thereof, Fig. 6 is a rear edge view thereof, Fig. '7 is a top view of the supplementary spacerforshort slugs, Fig. 8 is a view of a slight modification of the device.

` fThere is illustrated a' mold including the base 11 Aand the cap plate 10 of any usual construction, the base having the usual transverse channel or groove 12 at the left hand end ordinarily utilized to hold and aline the usual one-piece liners used at this point. Engaged between the mold elements there is a liner body or constant 13, correas tobreadth and thickness, having the usual rib 14 on the under side engaging .snugly in the groove 12, and having also the 'slot 15 spaced longitudinally thereof from spending in size to theordinary solid liner,

the rib, opening on the rear edge of the body and stopping short of the front edge a distance approximately one-third, more or less, of the width of the body.

The front edge portion of the body 13 is cut away as at 16 on the upper side for approximately half the thickness of the front edge, a series of longitudinally spaced apertures 17 being formed therethrough at suitable intervals, preferably about 6 points printers measurement. On account of the space ordinarily available in the. mold wheel of the linotype, my device may be constructed for use with that particular lmachine so as to project slightly beyondthe left hand endof the4 mold. Thebody 13 projects inwardly of the rib 14 as at 18. The iinner end edge is beveled toward the lower-"side, and toward the rear this end his provided with.a"V-shaped bay or slot 19, theforward side 20 yof which is inclined rearwardly 'from theangle outward,- and the rear side 20 inclined away from vthe rib 14 ,toward its outer end.l The angular, junction of the sides is located vnear the rib, and the sides are beveled toward the bottom sidelof thebody. Recesses 21 in .thl'form of small.' 4

notches are formed .onthe under'l side 'of ,rthe body opening 'from the edges oftheslot '19; and 'havingi'diverging sides.'

23 corresponding in cross sectional dimension and form to the slot and adapted to set snugly therein for adjustment longitudinally, having a pin 24 thereon adapted to engage snugly in one of the apertures 17. The inner edge and end of the arm 23 join on a vcurve concentric with the pin 24, so that the arm may be moved pivotally outward a distance when engaged in any of the holes. A, mold nead 25 is carried on the inner end of the arm 23 with respect to the` mold, having an outer mold face 26 at right angles to the arm 23, being of the full .width and thickness of the slug to be cast, and having the usual small teat 27 at the rear sidev projecting into the mold longitudinally. The back side 28 of this head, which is eX- posed at the back side of the mold slot, is'

inclined slightly toward the arm 23 from the mold face 26 for an important function to The head equals in breadth the arm 23, although this proportion is not arbitrary. The inner side of the head, disposed toward the constant member of the liner, is beveled toward the lower side throughout its. length including that portion over the base of the arm 23, which it will be remembered is but half the thick-- spacer or filling when a slug is ejected from the mold. Y

In use, the constant member is engaged in the mold in the same manner that the usual one-piece left hand liner is, the slot 15 receiving the stop screw of the mold (not shown).A The channel or cut away part 16 is exposed at the forward edge, and before securing-the cap plate of the mold, and while it is slightly raised, the pin 24 on the spacer is engaved in that opening which will allow the mold face of the head 25 to lie spaced from the right hand end of the mold a proper distance to give the length of slug desired. For convenience the bottom face of the channel may bemarkedwith a scale and numbers indicating the length of line obtained by engagement of the spacerwith the respective openings. The spacer is then swung inwardly until checked by engagement with the shoulder 29 comprising the inner side of the channel 16. The cap plate is then secured in position in the usual man ner, and the ordinary operation Aof the machine proceeded with. The casting of the first line lills the space between the head 25 and the constant 13, so that when the line is ejected, if the proper ejector blade is employed, the temporary filling of type metal indicated at 40, will hold the spacer rigidly in position. during ejectment of the slug. It will be observed that a space is left beneath the arm 23 between the head 25 and the inner end of Vthe constant 13, and in the operation of the usual linotype machine, the jaw of the matrice vise will close this opening and prevent the spilling of meta-l. Upon removal of the complete device after use as described, the filling 40 will tend to drop out from between the members 13 and 22, without manipulation, but should there be any tendency to stick, which is not believed likely, a slight upward lift on the head 25 while the constant is pressed downwardly will insure its dislodgment.

The inward inclination of the back face of the head 25 guards against accident in the trimming of the slug, in case the mold is imperfectly formed and allows the spacer to swing inwardly too far, so that in the event that the head is forced too far in when adjusting the device; and it projects from the back side of the mold slot, the' back trimming knife of the linotype can not be damaged nor the spacer broken, as the spacer will simply be forced or fended outwardly because of the acute inclination of the back face 28 to the path of the knife, not aording such a hold for the knife as to result in cutting of the head 25 or nicking of the knife. ln Fig. 8, there is shown a different form of the device which permits the portion 18 of the head to be made very short, and may be considered preferable to the first de- "scribed form. AHere,the inner end of the constant is simply formed with a. keystone slot 41, opening thereon, all sides of which are beveled toward the bottom of the device so that the temporary filling and buttressing type metal may fall out, as before described. This slot is located rearwardly of the series of apertures 17.

It will be apparent that wit-h the cap plate cf the mold lifted the illing 40 in either form of the device will exert no strengthening effect and will not hold the liner parts in rigid relation, for as soon as any pressure is applied to the rear side of the head 25, the liner parts will ride upward on the inclined surfaces of the filling, allowing their relative movement. It will be readily understood, however, that with the cap plate clamped in position, the interlocking of the liner parts and the filling will be as secure as though the edge portions were vertical instead of beveled; indeed, the strength .of the filling will be greater, on account of its increased cross sectional measurement, due to the vbeveling of the edges of -the liner parts, and especially so in the form shown in Fig. 8. j

It may be stated that in practice, the fillling 40 has never been found to stick, and

always has fallen freely from between the parts of the liner, even Without particular care in the oiling of the surfaces of the liner. The angle of the back face of the head with respect to the rear edge of the'mold', in practice, is less than that shown in the drawings. A scale 42 may be formed on. the lower side of the channel 16 and numbers marked thereon to 1'ndicate in any suitable way the space between the head and right hand end of the mold, the present method being to indicate in point measure the space subtracted from the maximum'length of themold space by inward adjustment of the spacer.
