TYPOGRAPHICAL CASTING-MACHINE.

Application led December 1i, 1914. Serial No, 874,960.

To all whom it may-concern: f'

Be it known'that We, CiiAiiLEs HOLLIWELL casting machines, particularly those l.lmown commercially under, the trade mark flinotype, and it has for its Aobject' to provide .means whereby, for particular classes of work involving the casting of typebars of different bodyv dimension, the trimming l:;.ives can he automatically adjusted in accordance with those body dimensions. i

Among the ahovenamed classes of work in connection with which the present invention could .be advantageously employed,

there. may be mentioned the casting of'typefhars, hereinafter termed Aslugsf suitable for the printing of Christmas cards, and auctioneers and various other catalogues, in which one item such for example as, in the case of a Christmas card, the name of the sender would be printed in larger type than would be the address or legend appearing on that c ard. v

The different sized slugs, say two sizes, involved in the use of thisl invention, would hotli he cast in the same mold, the cap of which would be'giooved to aIdepth which,

measuring from the bottom of those grooves to the' opposed face of the mold body, would frespond with the body dimension of. theV sli-ig suited to carry the characters of the largest hody dimension, and the distance be-v tween the surface of the inold cap between those grooves and the said opposed surface of tli mold hody would represent the body dimension of the slug appropriate to the Specification of Letters Patent.

PatentedAiig. 1, 1'916".

off lof-what have, in the past, been termed two-line letters, and the present invention involves the use of l trimming knife adjustable in substantialy the same manner.

Heretofore these two-line-letter knives have` had their, longitudinal motion restricted by their paths being intercepted by the twoline letters which it was intended should be retained on the slug, and which letters, if

the movement of the 'knife Werenot so restripted, would have. been shorn olf by. that kni e. 'l I The present invention involves among other new features, novel. means .whereby a knife Ypreviously set f or trimming slugs of one body dimension, can be released, by

overhanging projections cast. onthe slug, to

allow -it to assume the position .necessary tor trimming slugs of another b'ody dimension, but these projectionsl unlike the before-mentioned two-line letters, are pro-l vided solely for thepurpose of controlling the adjustment of thc `knife and are-shorn off by the latter after theyfhavefulfilled' .that function.

The invention will VVnow be described by' refe-rence to wliich:-' i Figure l is a front elevation-of Vsufficient of a typographical casting machine-to show' the application thereto of the present invention; Figs. 2 and 3' are plans of Fig. 1, showing the devices at respectively di'erent stages of their operation. i Fig. 4 is a perthe accompanying drawings in spective 'view of the improved movablev knife; Fig` 5 is aperspective. view and Fig.

6 an elevation of one ofthe improved character matrices; Fig. 7 -is an elevation ofone of the improved en spaces; Fig. 8 is a perspective view of one' of the slugs with the.

overhangmgknife-releasing projection still intact therewith; Fig.1 f) -is a. plan showingone construction, Fig. 10 a plan and Fig. ll an elevationshowing another construction, and FigfliZ an elevation showing a third construction ot adjustable movable knife accoi'ding to this invention.

The parts of the machine illustrated in the. drawings which are of ordinary construev tion, and -thus constitute. nofeature of the present invention, are, by way of distinction, indicated in chain or dotted lines.

According to the'present invention. thc adjustable-knife, which, as a complete en tity, is hereinafter identified by the refer! `ence numeral 1, is formed in what mai-f he regarded as two sections, these in F ig. AMthe.-

ing clearly 'distinguishable hy the nunierals 2,3 respectively, the trimming edge of the section 3 being in advance of that of the sec'- tion 2 and serving for trimmingislugs of smaller body dinension'timn those to be trimmed by the seetion 9.. By the term in advance as just employed is ineant a position nearer to the stationary or fixed knife 14 (Figs. l, 2. and 3).. In the arrangement each othe'natf'an ahrupt'angle.

, The knife 1 is arranged' to slide vertically v in a guide block 8 so as to bring one or the Aother of its sections i'nt-o active position or opposite the stationary knife 4i, a spring la tending constantly to raise the knife to its lipg'ierlnost position, and :L bar 1b, connected to thelower end of the knife and actuated by some suitable part of the machine, Abeing adapt/odioreturn the knife to its low'errnost position againstthe action of the spring.

tendingstad 6 (Figs. 1, 2 and 3)' which is The. knife 1 has fixed to it a laterally excapahle of moving in a vert-ical groove 7 in a'gliide block 8 in which Vthe knife l capable ef sliding ina vertical direction in ie spense to the action thereon of the aforesaid can! and spring. The guide 8 is, in Athe usual manner, attached to the vSo`called knife-block 3 Vwhich is in turn attached to the vise frame l0, towhich also as ordinarily isvseeured the beforeementio'ned stationary knifef.Y y

At the Vrear vof the groove? there 1s provided la horizontal sliding latch '1l which can he .projected into the groove, as shown in Fig. 2, and withdrawn from it as shown in Fig. '3, for engaging;'withl the stud 6, shown in the former figure, and releasing it as shown in the latter4 ligure. When .the latehll projects into the groove. 7 above the sind 6A the movable' knife l is held by' the engagement of the forrner. with the latter in its depressed position, asv indicate-d bestin Figs?, and it is while the kn'ife is in that position that it effects the trimming ofthe slug-s hearing charactersl of the smaller body' dimension; so long as this engagement of the iatch 11 and sind 6 continues, the section 2 ofthe knife cannot come into operation, hat when the latch l1 is withdrawi'i into the position in which it is shown in Fig. 3, the

meses@ knife l is raised by the aforesaid spring and the section L thereof is thereby brought into operative posit-ion to i1-ini slugs hearing characters of the larger bodyA dimension.

The slidingr Vlatch 1l is in pivotai Conner:L 70 tion' with a plate 12 adapted to turn about the vertical pivot 13 in fixed relationship to the `luide hlork 8, this pivotal connection being effected by forming a niek or reduced portion of the-latch ll wh'ichis embraced -7'5 by a slot 14 in the plate i2. A blade spring 15 fastened at one end to the guide block bears :it-rits otherend on the rea-r end of the latchll insuch manner as to constantly tend to hold the latch in, or return itto, its- 50 normal foremost position in'which it is in engagement,` or ready to engage,-.with the stud (3. Theforward end of the latch 11' is inclined at its upper side as indicated at 1,6 in Fig. 2, -so that when the stud 6, during g5 the' descent of the' knife. 1, moif'es'into con` tact therewith (the Said latch being then in its foremost position) it, thestud, pushes 4 the latch 11 rearwardly 'out of its' path, and

the said latchl after the stud has thus cle- 9o scended past it is iminediately-z` returned 'oy its spring 15 into its foremost'. position to again operate to prevent the',"ll:n if e`v 1l reach- Lingr its higher position. The, forwrdinove nient of the latch 11 under the tiction ofthe 95-VY spring 15 is limited by'theriglibhandiedg'eo f the plate 12, which, vby, abutting against the rear side of the gnideblockl' 8,-a's indi`` cated in Fig. 2, serves-11s a; stop for this pur-v from `the position -in which it isfs'liowii.in

Fig. 2 to that in 'which it is shown-in Fiel 105- This 'pivo'ted 'plateV 12' isadaptedto bel turned on its pivot 13v`in opposition tothe rinflnenee'of the spring-"llo bythe knife-releasing projeetionsnext tobe described, castfor thatspecial purpose oh these-id slugs.

In certain matrices-employed for casting slugs bearing characters 'of the. larger 'bodyv Y dimension, forv example, 'punctuation rnzit=l rices 195o-oh as-are shown in Figs?? and 6 oren spaces 20su`ch as are shown in Fig. 'I Us.

or character matrices having descenders snc-h asA the is, there are provided S119` pleinentalf cavities 21Whieh are instr'umenj` tal in producing'the'.aforesaid overhanging knife-releasing projections 22 on what may 12e he regarded as.the descendervside of the' resnltant, type character cest 0r. spaee produced. Each vof thesesupplemental 'cavities 21 is divided from' the main formative cavity 23 hy a sour-.24 which leaves .the 12' aforesaid resultant projection 22 attnehed to theslng'il' by a. thin and readily breakeole neck 25.

Vlhen thelsupplemental cavities 2i are formed on the en spaces Q0, as shown in Fig.

7, these latter are provided with other cavities 26 aliiicd with tlie. formative cavities 23 of the character matrices and divided from the said supplemental cavities by spurs 21 as in the example shown in Figsnvand 6, but the cavities 2G are not sufficiently deep to produce surfaces of' printing height; oonsequently the projections cast on the slugs in these .cavities cannot make impressions on the printed sheet, the said projections serv- 'ing merely tol provide a temporary support vfor the wei-hanging knife-releasing projections 22 cast thereon. i

' In the case of slugs vhaving characters of the smaller body dimension, there is' no necessity for the knife 1`-to be moved from its lowest position andeonseqiiently there aie no projections 22 cast-on those slugsA and therefore nothing to cause'the plate 12 to' turn on its pivot; consequently during the forward movement of the mold wheel, the

' latch 11,' then-in 'its forward voroperative position,is not disturbed,j and for the time being retains the knife'l its-lowermost'po- 'sitioiL with the section 3 t `ere`of in position to effect the trimming of the s'aidslugs.

For effectively carrying outthis invention there need not be more than one of the projections 22 caston each 'sl'iigrhving characters of the'larger body dimension, andif the line, in-connection with which the projection 22 is cast, contains no vpunctuation marks or descende'is, then the said 'ipiojections 22 can be .produced from one of! the aforesaid en spaces 20 which can-be inserted` into the composed line of matrices at or near eitherend thereof. u To enable vthe machine totrim` slugs of varying body dimensions, that'is to say,.

justment, however, in these fourhguresvis" shown as restricted to the upper section 3,Y

but it4 is to be `understood that if desired corresponding adjustmentof thelower -section 2 may he provided for` .as an alternative to or in conjunction with, the adjustability of the upper section 3. In each-of theA arrangements now under, review the`A knife 1`is formed of two main portions 2G and 27, the former bearing the before-described knife section 2 and `the latter bearing the knife section' 3.

.In the construction'shown in Fig. 9 the knife portion 27 isA capable of being secured 'in different positions on thepoi'tions 2G, by means of one or more clamping screws 2S,

and-when these screws 28 are released the part 27 can be finally Aadjusted on the part 26 by ineans of set'sciews 29 threaded in the last named part. and bearing against the right-hand edge of the part 27. After siich'adjustment by the set-screws 29 the two parts 27, 2G can lie-rigidly secured to gether by tightening the clamping screws '28.

In the construction shown in Figs.' 10

and11 the part 27 is lield, to the part 26 by two'screws 30 threaded .into the latter part, the heads of which are counter-sunk into the former part, and 4the pat` has vthreaded intoit thej stems ofv set? screws 31, the heads. 32'of which abut Vagainst the right-hand side. of the part 27,

these set-screws 31 Abeingvaljusted from theright-hand side of the knifebv a screwdriver engaging with slots or n icks (see'par--v ticularly Fig. 11) in the ri'glit-liand ends of their stems. To enable the part 27 to he adj usted relatively tothe part 26 the screws 30 are released and the setscrews 31 are' screwed .more or `less into Athe part 26 to` Y obtain the desired relative positions between the operative .faces 3, 2 of the parts 27,26, 'and after this adjustment has been secured the two partsinay be'iimlyisecured in the positions so varrived at by tightening the screws 30, which at the Sametime serve. 'to

AVlock the v'set-screws 31 'against vaccidental i'o'- tation.

In the construction shown inA Fig. 1 2 the part 27 is held totheipart 26'by tia'oscrews V 3Q the sem of each. ofwhich is threaded into nicks 34 whereby they canbeadjustedso as 'to project more rless from the part 26. YTo

lockV the bushesinany position to which they may be adjusted in the part 26 there are provided short headless screws threaded into thesame h olesras those infwhic-h the said bushes' are themselves adjustable. and when those screws are jammed against the right hand side vof the bushes 33. both such parts are locked against accidental displacement.

ics

In this arrangemeiit the' left-hand ends of the bushes 33 serve. for supporting the lpart '2.7

against the tightening pressure of the screws 3th, in thesa'memanner as do the screw-heads 32 in the 'exampleillustrated in Figs. 1()V and 11. .Jiaving described our invention we de claie thatv what we claiml and desire to secure by Letters Patent. is l 1.
