TYPOGRAPHICAL MACHINE.

Application-filed October 5, 1926, Serial No. 139,71 9. Renewed July 5, 1928. Y

My invention relates to typographical machines of the linotype classin which circulating. matrices are released by keyboard means from a storage magazine and assembled in a line in the order of their release, the assembled line transterredjto a position .in front of a niold in which a cast of type metal is made against the line of matrices,

and the matrices then returned to their individual channels in the magazine from which they were released. i a r This disclosure isdirected to machines or" the fmixer type in the class above referred to. In this type. of machine matrices from two or more magazines may be mixed in a single line in theassembling operation and thereafter automatically separated and distributed into the channels of the magazine in which they belong; The principal ob-.

jects in view areto provide a machine 0tv simplified and dependable construction and increased matrix capacity. Minor and COl1- tributing objects will be disclosed as the description progresses, and itwill be understood that the contributing features may be employed in machines of other than the mixer type without departing from the scope and spirit of the invention intended to be disclosed. Although but two magazines are illustrated and described, certain fea tures to be described may be employed in connection with machines having more than two magazines. Referring to the ,,accom panying drawings,-- 7

Inorder that the magazines 10 may be of the rectangular form shown in Figs. 1 and 2, I preter'to employ the distributor and escapement features disclosed in my pending application, Serial No. 139,721, filed October 5, 1926, towhic'h application reference may be had, particularly with regard to the mag inth'e prior art, those of the matrices X which are destined for distributio'n by a lower set ot'distributor screws are provided wlth a font-separating notch Xl, but in the present instance the lower set of distributor screws s'associated with the itppermagazme 10 and the upper set of distributor screws "distributes to the lower magazine 10?. Hence those matrices destined for the lower magazines are supported on a bridge 1 (Fig. 9) from the tiine they leave the usual distributor box rails 2 until they engage the teeth of the upper distributor bar 3 under control of the distributor conveyor.screwsand those matrices which have the notch X will be supported at the lower level on the bridge 1 and will not engage the upper distributor bar 3 but will drop from the end ,Of the rails 2, all in the usual manner. In the present instance I provide a stub conveyor screwv 5 terminating with the bridge 1 and in advance of the first m trix channel 11 in order that it will not interferewith entry of the matricesinto thefirst and succeeding channels. The fourth screw e controls the matrices destinedltor the upper distributor escapements until they have engaged the teeth of the distributor bar Thus the matrices are con-' trolled at their four. c'ornersby tourjscrews and will not twist inposition when supported on the bridge 1 as frequently happeuswhen but three screws are employed. This i'ourth screw carries a gear 8 which is in mesh with an intermediate gear 6 driven by a'gear 7 on the upper screw 4;. it thus controlled the matrices destined for the uppermagazines are insured reliableentrance into the opposed grooves 11 lo'r purposes to be explained, while matrices destincd'ior the lower magazine arecarrie't'l beyond" the bridge 1 bymeans of the usual distributor screws.

It will be noted thatonly a single distributorjbox A is employed no additional boX being contemplated in this invention, and the single box may be of usual type. In order that the matrices maybe distrib- "uted into two magazines with'tliis condition of common and simple construction, 1' provide as follows: The lugs of the matrices X engage the opposed grooves 11 in the same manner that theyengage the usual channels of the magazine. Through the floor of the lower channel Iprovide two openings 12 and 13 ofsuliicient size to permit the entrance or the'forward and shorter lug of the matrices but small enough to bebridged by the following and longer matrix lu'gz' As eachs ucceedmgmatrix entersthe channel 11 lts forwardlug enters the opening 13 and lodges v until lifted out by means of an escapement The escapement 14 element 14 (Fig 6). reciprocatesonce with each rotation of the lower set of distributor screws. To this end an oscillatin plate 15 is pivoted beneath the channel 11 on a pivot rod leand controls the movement of theescapements 14. The

oscillator'll'i isactuated by means of a cam 17. onithe outer end of one'of the distributor screws 1 thus insuring movement of the escapements 1a in time with the rotation of the distributor screws. The cam 17 may be provided with an anti-friction roller 18 to prevent wear. The return movement of the oscillator 15 is accomplished by means of a spring 21. The two openings 12 and'13 are provided in duplicate in order to prevent two thinmatrices overlapping-each other in the channel 11 in the eventof adis'trlbutor stopor other abnormalcondition. The

lower distributor screws are each provided with two threads, 1 of which is idle as a,

conveyor tbread and terminates short of the entrancechannel 11. Escape oi the'matrices from the lodgement 12 is so timed with the rotation of the screwsthat the other thread Z) on the first screw 1 will not interfere with the lugs'of the matrix as it moves across the reduced portion a of the screw,'"nor will thread 6 on the secondscrew 3 interfere with the forward lug of the incoming matrix; but when the matrix lodges against a stop 19 at the end of the channel 11 the threads Z) will engage the lugs'of the matrix and convey it to the appropriate magazine channel. Openings 21 and 22 in the walls of the channel 11 provide clearance forthe matrix lugs when the matrix moves laterally from its channel position under control of groove otthe screwb'eing of such size and steepness that the longer lug of the matrix can not enter "thereini l r' Theset.ofdistributor screws forthe up per magazine, the associated distributor bar 1, and the member 20 111 whlch the grooves 11 are formed are mounted in common on the channel entrance 9 of the lower magazine; therefore ready access may be hadto both vniagmzlnes and their entrances by swinging the EHtltlllCBSlJO the position shown in dotted lines in'Figfiu The distributordriving mechan sinas illustrated-1n Figs. 7 and 8 is of such construction that when the trances,'hence the gears on theends ofthe other and with the unvei- 522 when the distributor issWung downward as shown in dotted lines; liltewise,the driver 22' isiiitegral with a larger gear 241 which remains in mesh with a gear 25 of like size centered with the driving pulley 26,'which is associatedwith theu'pper distributor driving mechanism including the driving clutch common to both distributors. The driving clutchillustrated is similar to that described in my Patent No. 1,389,369, hence is not here described in detail.

'Ea chof the magazines is intended to contain two fonts vor sets of matrices, of different design or'size, the matrices of each font being disposed V in alternating magazine channels. For efmmple the. first channel would contain a lO point e, the second channel an 8-point e; the third channel a lo point tl, the fourth" channel an 8-point t; etc. Theretoreyjtwo sets of matrix esc'apement are provided for each magazine. The escapemeiits are actuated by reeds 31 controlledfrom akeyboard in usual manner.

showmthose associated'with one font of matrices occupying one position and those associated-with an alternating font occupying a relatively o'l'tset position; hence, moving the upper ends of the reeds from one to the'other of the sets of escapementsselectivel'y, will cause a selected font of matrices to be released when the keyboard is operated.

The two sets of escapements 28 for theupper magazine are all alike, but they are actuated by two sets of intermediate levers 29 and 30, differing in length according to which of the two sets of escapements they actuate. The ends of the longer levers 29 r are offset to a; position in front of the shorter levers 30 (Fig. 10), and the'contact points 27 of the escapements 27 on the lower magazine are bent in alternating directions to positions in alinement with the contact ends of the levers 29 and 30. It will be apparent that if the upper ends of theactuating reeds '31 are moved from one to another ofthese four alnnng positions, any one of four fonts of matrices may be released accordingly. The levers 29 and are pivoted on a rod 32 and raise the upper magazine escapements when the reeds 31 are actuated by the keyboard means, the escapements 28 being pivoted in series on a rod 33 carried by a stationary portion Set of the assembler ent'anc'e throat. A middle portion 35 of this throat is movable on a pivot 36 from the. position shown in Fig. 8 to a position in register with the lower magazine for con ducting matrices therefrom. A middle por- 7 40 (Fig-10) in the edge of a springcon trolled supporting plate ll pivoted on the throat by means of a rod as. The upper end of this supporting plate is held substantially spaced away from the throat 35 by means of links 43 which are bent at a right angle beneath an anchoring bar 44, and at their upper end are similarly bent to limit the movement of the plate 41 under pressure of a spring 4-5. lVhen thethroat 35 is lowered to register with the lower magazine,

the initial movement thereof will' permit the spring 4-5 to expand and the plate 41 will closely engage the throat and permit the es capement elements 29 and 30 to drop about their pivot 82 and thus remain in a. 11011 nterfering [)OSlt-lOllIQlttlVG to the escapements 27 when the lower magazine is operative. Following' the initial downward movement of the throat 85'the lower bent endings of the links 43 willmove-away from theanchoringlbar 4 4; and when the throat I is restored to its upp er position the links 44 will limit themovement of the platetl tion.

andthe final movement ofthe throatiwill cause theescapementelements 29 and 30' to dragon the plate il and thus be raised to operative position. Both the movement of the throat 35 as above described and the movement of theescapement actuating reeds 31 to a selected one of their four operative positions are controlled by means of a crank-handle 46011 a shaft 47 mounted on the lower rigid portion 48 of the assembler throat. A; cam 49 is secured to the crank arm 50: and shaft 4L7 and fits between arms 51 and 52 of a bracket rigidly secured to the mo able throat 35.

When the longer radius of the cam isin engagement with the arm52 the throat 35 is thereby held in its upper position, and when the handle 46 is moved to its opposite position the longer radius of the cam will engage the arm 51 and thus move the throat to its lower posi without affecting the position of the throat,

and this limited movement of the handle causes the reeds 81 to move to a selected one ot the two POSllllOIlS thereof associatedwlth either magazine. To lllllS end the reeds 31 'are guidcd and spaced apart as usual in a suitable bar-"54: secured at oppositeends to supports 55 reaching from a pivotal posi-. tion on the keyboard; A link 56 101118 the support 55 to the cam 49 at an off-center point, and a slight movement of the handle 46 willtherefore cause a pCOI'IQSPOHdiDg movementof the series of reeds 31 for the purpose'of placing their ends beneath a selected alternating series of escapement devices. Similarly; the initial movement of' the handle, 46 when lowering the throat 35 will move the reeds beyond the ends of the escapement devices 29 in time to permit the members 29 and 30 to drop when freed from the supporting plate 41, This is the position of the reeds in Fig; 10L-The shaft 4-7 may extendacross and beyond each side of the throatlS'andzthe bracket 58, cam 49 and link 56 be provided in duplicate. at opposite sides of the throat 48. The hinge-pin 36 for the bracket 53 enters a suitable extension 57 of therigidsportion 48 of the assembler.
