LINOTYPE -MAOHINE Specification of Letters P at'ent.

, Patented June 2, 190a.

To all whom it may concern:

Be it known that I, DAVID S. KENNEDY, of

borough of Brooklyn, county'fof Kings, and

State of New York, have invented-a new and u eful Improvement in Linot" e-Machines,

e following is a specification.

chines of the general organization represented in' Letters Patent of the v United States #436,532; In these machines, type metal slugs, bearing-on one'edge the'characters to print'an entireline, are cast'in a slotted mold agamst an assembled line of.-- matrices. The mold is mouni ed in a vertical 'intermittingly rotating whee bywhichit is presentedfirst inahorizontalcasting position, and thereafter in a vertical position in front of the reciprocating ejector-blade, by. which the contained slug is driven edgewise from the mold and between two. parallel trimming knives into the receivinggalley atthe front, The hot metalshaved from the side faces of the slug' by the knives clings with considerable tenacity to their edges, and'un'less removed, the shavings are liable to lodge upon and impair the faces of succeeding slugs. For thls reason, all machines, of thisolass'are provided with .wipersof one form or another to remove the, adhering.

metal from the-knives after eachi'shavi'ng. ope'ration.-; As heretofore constructed, wip

ing mechanism'shave' been open to various objections such as 7 their opmplexity, their dependence upon; springs, their liability to stop in the path 'of the ejector-blade, etc. My invention relates to an improved, form .In the drawings,' ,-Figurel1' is- I a perspective view of the knives and thewi-ping 111G011:

anism in operative relation thereto. Fig. 2;

is aside elevation of-the same. Fig. 3 is'a face view of the viseeframe with-the knives and adjacent parts,looking,i'rom the rear tween which the slugs are elivered facewise' from themold to the galley.-- 0 represents the first elevator,v so-cailge'd, ,for suf porting,

the line of matrices-andpresenting t e same ide. vertically in'the main-frame; and has a .fixed travel ongitudinally over t frame. r V g F isan actuating link, pivoted atone endtolthewiper-rod E, and atthe other end to a 'ives presenting arallel edges be-f length, ofltravel. far 'as described, the parts are of ordinary construction,

, Dre resents the lm'ife-wilper designed to e edges of the twoknives in contact therewith,.or in close proximity thereto,- the latter arrangementeirlg preferred. This .wiper,-which-1s preferably in the form of a metal plate, but whichmay be a brush or a pad of 'felt or other suitable material,,is attached to the upper end of a vertical rod E, which is guided at its upper and lower endsin the mainlever-G whi'chis mounted at its middle on a horizontal stud orpivot g on the main-frame. The leverG is actuated by a stud ,or-roller-H on the elevator-slide C, as shown in" and, 2. The elevatorO has a; movement Figs. "1 I greater than that required of the knife-wiper,

and its movements arearrested at such points and at such times that a positive connection between the elevator and the wiper-rod is impractical; For these:reasons,'and in order thatthe knife-wiper may remain at rest in the-required position while the elevator C is in motion, I provide for lost motion between theelevator-slide andthe lever by giving the 7 "forward "end of thelever the form shown'in. Figs. 1 and 2, that is to'say, with a riotch g" 1 I its .upper portion, and an extended outer surface g' beIOW the notch.

Duringthecasting action, the partsstand in'the position shownin Fig. 1, withjthe stud H bearm on the flat surface of the ever, and Y holding it e latterand the .wiper D-.in their. up ermost-ip'o'sitions- As the elevator-rises su seduentfto' the casting aotion., the roller travels upward-on the surface g -while the wiper remains at, rest, until finally the roller enters-the notch g as shown in Fig. 2,

whereupon it-tans es the lever to move and draw the wiperD downward the entire length a of the knives. Asfthe elevator descends, the lever is positively actuated bythe stud H ,tr'av'elin downward in the'slot g and throw-. ,ingthe' ever to the position shown'in full lines in Fig.1, and the knife returned to its u permost position and there held at rest w h l e the elevator C com letes its downward movement. As. the'lmi e reaches its upper+ most position, the surface g assumes a vertical position and] the lever remains at-rest while the stud continues to travel downward being no possib over said surface. It will be observed that the knife is moved positively in both direc-- tions and through'a definitedistanoe, there ity of its failin to move or of its being arrested in-the P8151 of the-Sadvfancing ejector. The essence. f the inventionlies in moving the knife positively in both directions through a device receivin motion from the elevator C, and in so forming the parts as to permit the dwell or rest of the wiper while. the elevator continnes-tomovef I In machines used for certain purpo'ses,it is customary to use a single knife trimming one side of the slug only. It will, of course, be understood that mywiping mechanism-may be used in such case In connection with a?- single knife, :and that such arrangementwill fall within the limits of my invention and theclaims hereinafter stated.-

' It will be obvious; torthe" skilled mechanic 'thattheform' of the forward end of the lever said lever having one end provided with the' .notchlg and surface 9 G may be modified without changing its mode of action; for example, it may be eX- tended as shown 'in'dotteddines in Fig. 2, so as to form an ,angulanslot inclosing the roller H. Having thus described my invention, I- claim and desire to secure by Letters Patent, Y
