to receive ink from a softinking-roller, and the inked portions may then offset or cause a smudge V of the printed sheets in the areas which should be left blank and unmarked by the printing operation. To avoid such undesired effects, it is the common practice of printers to cut down or reduce the height of the-shoulder portions of typeslugs, particularly when a plurality of adjoining slugs have blank portions, the cutting down of the slugs being done in some cases by handchiseling after the slugs have been assembled in the form, and in other cases the slugs being trimmed by sawing off the upper portions of the shoulders. When the slugs are trimmed by sawing, the thickness of metalremoved from the shoulders is not more than the thickness of the saw,'and usually the trimming of each slug is done separately. Itis the object of my invention to provide an efiicient-an'd economically 0perable machine for rapidly trimming or routing the blank shoulder portions of type-slugs any desired amount, the'mechanismbeing adapted to operate simultaneously upon a large number of slugs, whereby 'a'group of ,the slugs to be trimmed may be placed by the operator in the movable galley or holder, the slugs caused to be automatically gaged so that the blank portion at one end of each slug projects from a common gage or alining member, the slugs then clamped or locked in gaged position, and the entire group of slugs then moved past a rotary cutter adjusted to remove from the shoulders the required amount to reduce the blank portions of the slugs to the desired height. Further objects of my invention relate to the particular construction and arrangement of the means for supporting, gaging and clamping the slugs, and for alining, guiding and supporting the slug-carrying mechanism during the routing or trimming operationa'and will be more fully set forth hereinafter.

In the accompanying drawings, Fig. 1 is a partial plan view of a machine embodying my invention, Fig. 2 isa rear side view or the same with the tilting galley in the position at .which the trimming operations upon the slugs is completed, Fig. 3 is a front end view of the machine, showing the galley in horizontal loading position, Fig. 4 is a vertical transverse section on the line 44 of Fig. 2, Fig. 5 is a detail rear side View of the slice-stop adjusting device, Fig. 6 is a detail section on the line 6-6 of Fig. 5, Fig. '7 is a longitudinal vertical section on the plane of the lines '7--7 of Figs. 1 and 3, showing the-galley in vertical position, Fig. 8 is a vertical transverse section on the line 8-8 of Fig. '7, Fig. 9 is a section of the galley on the line 9-9 of Fig. 7, and Fig. 10 is a detail section on the line 10-10 of Fi '7.

In carrying out my invention according to the illustrated embodiment thereof, I provide a fiat v hollow base-plate 11, which is supported at a convenient height by any suitable means, and

which has thereina central longitudinally extending approximately rectangular opening 12. Near the ends of the base-plate, laterally of the opening 12, are mounted a pair of brackets or standards 13 and 14, in the upper portions of which are secured the ends of a horizontal shaft or guide-rod 15. Slightly below and laterally of the guide-rod l5, and extending parallel therewith, is the rectangular guide-bar 16 of which the ends'are secured to lugs 1'7 on the standards 13 and 14. The central part of the guide-bar 16 is further supported by a bracket or standard 18, secured to and extending up from the base-plate 11, as shown. Secured to the base-plate, and extending longitudinally between the lower portions of the standards 13 and 14, is an angle-bar 19 which forms a lower guide-bar, extending parallel with the rod 15 and bar 16; The described base, standards, and guide- members 15, 16 and 19, constitute the fixed frame of the machine on which the movable operating parts are mounted.

A galley is formed by a flat rectangular plate 20 having parallel flanges 21 and 22 formed integrally therewith and extending upwardly from is longitudinal edges, there being integral lugs 23 and 24 extending downwardly at the intermediate portions of said longitudinal edges, and lugs 42 and 43 extending upwardly at the intermediate portions of the flanges 21 and 22'. The guide-rod 15 extends through alined openings in said lugs 23 and 24, whereby the galley is slidably and t-iltably mounted upon said guide-rod. The galley is normally positioned horizontally at the front end of the guide-rod, adjoining the standard 14 as shown in Figs. 1 and 3, and at this, position a projecting portion 25 on the lug 24 extends into a notch 26 in the upper edge of the guide-bar 16, whereby to prevent sliding movement of the gelley along the guiderod. From the normal horizontal position the galley may be tilted to a vertical position, as shown in Figs. 4, 7 and 8, and at said position the projecting lug portion passes out of said notch 26, to a position above and adapted for sliding contact with the upper edge of the bar 16, as best shown in Fig. 4. When the galley is in vertical position a stop-bar 27, secured upon the lower end of the plate 20, engages the lower guide-bar 19 to stop the tilting movement, and a portion of said bar 27 passes through a notch 28 in said bar 19, so that a longitudinal groove in said stop-bar 2'7 in register with the guide-bar, as shown in 4 and 8. The widlh of the notch 28 in the guide-bar 19 is substantially the same as the length of the grooved stop-- bar, so that when the galley is moved longitudinally out of register with said notch 28, a portion of the guide-bar enters the groove in the stopbar and prevents tilting of the galley from the vertical position. Sliding movement of the galley rearwardly alon ihe guide- members 15, 16 and 19 toward the standard is yieldingly limited by'a coil spring 29 disposed around the rod 15, said spring being engaged by the lug 23 and pressed against the standard 13, as shown in Fig. 2.

The inner sides of the flanges 21 and 22 are grooved adjacent to the plate 20 to receive slidably a thin plate or galley-slice 30, said plate or slice having at one end on the upper side thereof an end-bar 31, and having at its other end a laterally extending finger-bar 32. Adjacent to the flange 22 of the galley, and extending longitudinally parallel therewith, a rectangular bar or side-' rail 33 is affixed to the upper of the slice S9. Fitting slidably between said rail 33 and flange 22 is a plate 34 having upon the intermediate portion thereof an integral tongue 35 extending first upwardly, then laterally above the flange 22, and at the outer end turning downward to form an inverted U-shaped bracket. through the plate 34 and the outer portion of said bracket is a pin 36 having a head 3'? at the outer end thereof and a cylindrical head 38 at the inner end thereof, the portion of the pin adjoining the inner head 38 passing through a slot 39 in the rail 33, and said head 38 being normally seated in one of a series of circular recesses 40 formed in the inner side of the rail, as best shown in Figs. 5 and 6; A spring 41 is coiled about the pin 36 between the plate 34 and a collar formed on the pin adjoining the outer portion of the bracket 85, and said spring thus serves to push the pin outwardly to retain the head 38 in the recess 40 in which it is engaged. By pressing inwardly on the head 37 the pin is moved longitudinally to disengage the inner head 38 from the recess 40, as shown by dotted lines in Fig. 6, and the plate 34 may then be moved longitudinally to adjusted positions relative to the rail, at which the head 38 is again seated in one of the recesses 40 to retain the plate in adjusted position. The plate 34 forms an adjustable stop for limiting movement oftho slice 30 downwardly when the galley is tilted to its vertical position, the movement being stopped by engagement of the tongue 35 with the lug 43 on the intermediate portion of the flange .2.

Extending parallel with the rail 33, between the same and theflange 21 of the galley, is a clamp rail 44 which is carried upon the front end of a rod 45 extending slidably through the flange 21. At its rear end said rod 45 is secured to a block or head 46 carried upon the rear end of a rod 47 which extends slidabiy through the lugs 23 and Extending slidably nesaoss the shoulder at the end of the reduced portion of the clamp-rail forms a stop to prevent withdrawal of the slice from the galley. In the operation of the machine, preparatory to the trimming of a group of type-slugs, the galley is disposed in its horizontal position, and the slice 3G is moved to the left, as viewed in Fig. 3, until the end-bar 31 engages the described stop formed by the shoulder of the clamp-rail. A group of the slugs S is then placed upon the slice adjoining the rail and the knob 48 is pulled to lightly engage the clamprail 44 with the opposite or rear side of the group of slugs, to thus retain them in vertical edgewise position while permitting them to slide freely longitudinally, relative to each other. The s ugs are then gaged, or automatically assorted according to the length of the blank portions thereon, and then clamped in gaged position, by the following means:

In the lugs 42 and 43, which extendup from the galley- flanges 21 and 22, there is mounted a rocking-shaft 49, on the intermediate portion of which is carried the gage-bar 50. The gagebar is connected adjustably with the shaft 49 by means of a pair of flat arms 51 and 52 arranged at one end thereof, the arm 51 being secured .to the end of. the gage-bar and the arm 52 being afiixed to the shaft. A pin 53, mounted slidably in a lug at the outer end of the arm 51,

has an end portion adapted to enter any one of and gage-bar to the desired adjustment, at which the lock-pin is engaged with another of said holes 54. The lower side of the gage-bar is so spaced from the slice 30 that type-slugs-may pass beneath the same, but upon the lower side of the gage-bar is an integral lip 55' which pro jects toward the slice, said lip. being offsetlaterally from the axis of the shaft 49, as best shown in Fig. 8. In the normal or usual adjustment of the gage-bar and rocking-shaft, at which the lock-pin is en aged in the central or intermediate hole 54 in the arm 52, the gage-lip 55 is so spaced from the slice that the untrimmed shoulder portions of the slugs S may pass-beneath the lip, but the type-portions of the slugs, which extend up from the shoulders thereoflcannot pass the lip. Thus, a group of the slugs S, resting upon the slice 30 and held loosely between the rails 33 and 44, may be moved longitudinally to pass beneath the gage-bar, either by moving the slice while the galley is in horizontal position,

or by inclining the galley and allowing the slice and the slugs thereon to move downward by gravity, and the several slugs of the group will be automatically gaged or assorted, so that the blank portions at their lower ends will project '55 against the adjacent shoulder portions ofthe slugs, said clamping operations-being-effected as hereinafter described.

On each of the ends or the rocking shaft, which project laterally from the lugs 42 and 43, an arm 56 is secured by means of a pin 57, said arm extending diagonally downward from the shaft. Beneath each arm 56 is a resilient tongue 58 formed integrally with an upper U-shaped portion 59 which straddlesthe hub of the arm and 'pivotally engages the'shaft 49 at opposite sides of said hub. An adjusting-screw 60 extends through the arm 56 and engages the resilient tongue to maintain an adjusted spacing of the arm and tongue. A small spring 61 is connected withapin 62 on the side of the flange 21, and to -'a pin 63'on the adjacent arm, 56, said pin extendingthrough an opening in the tongue 58, as shown in'Fig. 10. The tension of said spring 6-1 normally holds the tongue 58 on the opposite side of the galley against a stop-screw 64, carried at the sideof the'flange 22. The't'erminal portions of the tongues 58 engage cams '65 on the clamp control member, which comprises a pair of arms 66 and "6'7 having said cams formed on the hub portions thereof, said-arms being mounted pivotally on the clamp-rod 47 adjoining the outer sides of the lugs 23 and 24, the arms being connected by abar 68 formed integrally therewith, and said bar 68 extending-past the arm 67 and having a handle 69 extending laterally from the front end thereof, as best shown in Fig. 9. In the normal horizontal position of the galley, shown in Fig. 3, said handle 69-'eX tends diagonally downward, a lug 70' on the bar 68 engages the lower side of the lug 24 on the galley, and a lug 71 on the lower side of the arm 6'7 engages an inclined part '72 on the standard 14, whereby said lugs serve to form a rest or support for the galley at the horizontal position thereof. When the galley is raised or swung to its vertical position, the handle 69 may be moved downwardly to the position shown in Fig. "4, whereby the arms 66 and 67 are swung about the c1arhprod 67 and actuate the cams 65 to press upwardly uponthe tongues 58, thus rocking the shaft 49 to move the gage-lip 55 toward the type-slugs beneath the same and clamp said slugs e'dgewise against the slice 30, Also, by the movement of the clamp-control handle to the above position, shown in Fig. 4, the rail 44 is caused to clamp the group of slugs between the same and the rail 33, said clamping action being effected as follows:

' On the clamp-rod 4'7'adjoining the lug 23 is disposed a clutch-sleeve -73-which is formed integrally with an arm '74 connected pivotally with the plate 20 by a screw '75. A small spring '76, arranged between the arm '74 and the lug 23, normally holds the sleeve '7 3 against the side of said lug 23-, and at such position the-rod 47 is freely slidable through-the sleeve. At the end of the clutch-sleeve adjoining the lug 23 there is a small flange '77 having a beveled side, and a pin78' on the arm 66 is arranged to engage the-beveled side of said flange as the control-member is moved to clamping position, whereby the clutch-sleeve is pushedaway from the side of the lug -23. By said movement of the clutch-sleeve the same is slightly tilted relative to the axis of the rod 4'7, due to the pivotal connection of' the arm '74 with the galley-plate 20, and the sleeve is thuscaused to first'cramp or bind upon the rod47, -after slightly more which the further movement of the sleeve carries the clamp-rod with it, said movement ofthe clamp-rod being communicated to the rod 45 and causing the rail 44 to be pressed toward the rail 33 whereby to clamp the slugs between them.

As the movement of the rods 47 and 45, caused by the clutch-sleeveis necessarily quite small, it

is desirable that the knob 48 be pulled forward, to press the rail 44 firmly against the slugs, be-

fore moving the control-member to clamping position.

After the group of slugs in the galley have been gaged and clamped, and-the galley is in its vertical position, as described and as shown in Figs. 4, 7 and 8, the galley is moved rearwardly along'the guide-rod 15, whereby the blank shoulderportions of the slugs, which project beyond the lip 55of the gage-bar, are carried past a rotary cutterwhich trims the projecting portions of the slugs to the desired'height. In the structure shown the cutter comprises a disk 79 having a plurality'of bits 80 adjustably secured therein by set-screws 81, and projecting from the face thereof. The cutter is driven byand carried directly upon the shaft of a motor 82 mounted on the base-plate 11 at the side of the opening 12, the cutter-disk being thereby positioned above the opening 12 in the base-plate, so that the chips or cuttings from the slugs-may fall through the opening into a suitable receptacle disposed below the same. To prevent scattering of the chips of metal cut from the slugs, and also for the protection of the operator, a guard 83 is secured to the galley at the front side thereof, as shown,

the same being adapted to cover or partially in- 1;. close the cutter-disk as the galley is traversedalong the guide-members during the trimming operation upon the slugs' At the extreme travel ofthe galley, the spring 29 is compressed, and

the slice-rail 33 passes the vertical plane of the Upon approaching the horizontal position, the

lug '71 on the control-member engages the inclined part 72 on the standard 14, and the control-member is thus moved automatically to the described release position atwhich its handle 69 extends diagonally. The clamp-rail may then be moved to free the slugs, and the slice 30 moved to the left, by means of the finger-bar 32, to carry the slugs from beneath the gage-bar. If the slugs have blank portions at both ends thereof, they may be lifted from the slice, placed in reverse position thereon, or with the untrimmed ends toward the gage-bar, and the gaging, clamping and trimming operations repeated.

' The stop-plate 34 is adjusted according to the total length of the slugs which are being trimmed, so that when the forward or downward movement of the slice is stopped by the engagement of the tongue 35 with the lug 43, theiend-bar 31 of the slice will be spaced from the gage lip 55 but than half the length of the slugs. Thus,'when the galley is in its vertical position and the slice has descended as far as permitted by the stop-plate, the end-bar 31 forms a stop to prevent an excessive portion of a slug projecting beyond the gage-bar, should the slug be entirely blank, or have a short printing-face occupying less than half the length of the slug.

It is sometimes desirable to form low slugs, for spacing or leading forms, by trimming down the entire length of blank slugs of the usual height formed by type-line-casting machines, or by similarly trimming slugs having undesired printingfaces thereon. Trimming of such slugs is facilitated by adjusting the relation of the gage-bar and rocking-shaft by means of the arms 51 and 52 and the lock-pin 53. When said lock-pin 53 is engaged in the left-hand hole 54 in the arm 52, the gage-lip 55 is raised sufiiciently to allow a slug having printing-faces thereon to pass beneath the lip, and when the lock-pin is engaged in the right-hand hole 54 the lip 55 is lowered to a position at which it may clamp or press upon the low shoulder formed by trimming the slugs. If slugs having printing-faces are to be trimmed, the gage-bar is first adjusted to the position at which the lip 55 is raised to enable the printingfaces to pass thereunder, and the slice-stop is adjusted so that the end-bar 31 limits the projection of the slugs beyond the gage-bar to slightly more than half their length. After gaging and clamping the slugs, the same are then trimmed in the usual manner, the galley returned to normal horizontal position, the slugs released, placed in reversed position and gaged by the endbar 31 so that the untrimmed portions project beyond the gage-bar. The latter is then adjusted to the position at which the lip 55 is lowered sufficiently to clamp the trimmed portions of the slugs, and the same are then clamped and trimmed as before. If blank slugs are to be trimmed, the initial adjustment of the gage-bar is the same as for ordinary trimming operations,

at which the lock-pin 53 is in the central hole 54 in the arm 52.
