' `TYPE-MAMNG. MACHINE. I' i' i Be it known tliat..I* RUDoLPIil C. VETTER, of Syracuse, in the'cointy..of Ononda a, in the State of New York, khave invente new and useful Improvements inl Type-Making Machines,l of which the following, taken in connection with the accompanying drawings, f is a full, clear, and exact description.

-This invention relates to certain improve- `ments in type-making machines, and is especially adapted for the economic manufacture of type which are to be fixed to the type-bars of type-writing machines. These t pe are preferably made from suitable stoc -metal'l lsuccessively presented to `the vmatrix and irmly held during the-o eration'ofy making.

the impressionby theyro ling contact -of the matrix therewith.

One of the essential objects, therefore, of my present invention is to'y provide a series of blank-holding devices by which the blanks may be successively brought into position to receive an impression from the matrixl and to enable the operator toy supply theblanks to the .holders during the "impression-making operation, lthereby obviating loss :of time, such as Awould occur if'but a single holding de- .vice were employed. This object', more specifically stated, isto provide the machine with a rotary turret having a plurality of chucks or holders adapted to receive and retain the blanks and to successively feed them y into position to receive. an impression from an oscillatory matrix and to employ'suitable mechanisms for lockin the turret in its adjusted position during tIie impression-making operation and for ejecting the type-plates from their respective holders as they are successivel formed.

Anot er object is to provide means for automatically rotating the turret step by step or one clutch-space at a time during each cycle of operation.

A- further object is to mount the matrix in a suitable oscillatory support which is fulcrumed at one end by intermeshing teeth located in the plane of rolling contact of the matrix with the blank kin which the type are l formed and to-seat lthe opposite end of the,

matrix-support in, ak reciprocatory curved bearing actuated transversely of the recipro- "PATnNr orrrc,

c atory action of the` turret-supporting carriage, so that the matrix support is held solel at its endswithout intermediate connections for producin *a perfect 'rolling contact ofthe matrix witV the blank, and thereby obtaining a more perfect formation of the type A .still further object is to provide means for the adjustment of certain mechanisms to `take up any incidental wear or lo'st motion.

Other more specific objects will be brought out in the following'description.

In the drawin s, Figures 1 and 2 are respectively top p an and side elevation of a type-makmg machineV embodying the various lfeatures of my invention. Fi s. 3 and 4 are longitudinal vertical sectiona views taken, respectively, on lines 3 3 and 4 4, Fig. 1.

Fi ."5 is atransveise vertical sectionalview en on line 5 5, Fig. 1, showing particularly ism into and outl of connection wit the carriage-feeding mechanism. Figs. 6 and 7 are the means for throwing'the drivin mechanuired and also tofsimplify the operation of t e several mechanisms so as to increasethe permanenc `and durability vof the machine and t ena le itto be o erated by com aratively chea or unskille labor without liability of undu y im airing any of its mechanisms suitablematrix 5 by means of a rotary cam 6 which is mountedu on and secured to a shaft 7 and is rovided with a circumferential camgroove or receiving a roller 8 upon the carriage 3, whereby the carriage is positively actuated back and forth along the ways 2.

The shaft 7 is provided with a worm-gear 9, which meshes with a worm `10 upon an up- IOO right shaft 11, which is connected by mitergears 12 to the main driving-pulley 13. This ulley 13 and one of the gears 12 are interlbcked with each other and are loosel mounted upon a fixed stud 14, `which `1s screwed into the adjacent end of the frame 1.

The uprigiht shaft 11 is journaled in a" latter is provided with a rol er 16, which is held between the arms, as17, of a bifurcated sliding yoke 18, the adjacent faces of said arms being provided with inclined cam-faces 1-9 for engaging opposite faces of the roller 16 and forcing the upper end of the shaft transversely of the axis of the cam-shaft 7 a sulficient distance to throw the worm 1() into and out of engagement with the worm-gear 9.

The sliding yoke 18 is actuated back and forth by means of a lever 20, which is pivoted at 21 to the frame 1 and is provlded with a lengthwise slot 22, receiving a pin 23 on the yoke 18, whereby motion is transmitted from the lever to the yoke 18 to rock the shaft 11, and thereby move the worm 10 into and out of mesh with the worm gear 9, which is secured to the cam-shaft 7.

The roller 8 is mounted on a stud 8 on the lower end of an adjustable head 3, which is slidable in suitable ways in the carriage 3 and is provided with an upwardly-projecting threaded stud 24, engaged by a nut 24, by

which the head 3 is clamped in its adjusted position between opposite adjusting-screws 25 and 2 6, as best seen in Fig. 4.

The adjusting-screws 25 and 26 are engaged with threaded apertures in the opposite ends of the o ening, as 27, in which the head 3 is movab e endwise to permit proper adjustment of the roller 8 to register with the cam-groove, as 28.

Substantially one-half of the cam-groove 28 is deflected oroffset axially suiiicient to bring the operating-face .of the turret 4 into and out of engagement with the matrix 5, while the remaining half of said groove is disposed at substantially right angles to said axis to hold the turret with one of the blanks in contact with the matrix during the impression-making operation, which is accomplished during half a revolution of a cam 6.

The offset portions of the cam-groove 28 are of comparatively steep pitch, so as to quickly advance and return the turret-supporting carriage to and from the matrix.

The turret 4 is rotatingly mounted upon a transverse horizontal axis in suitable bearings 29 upon the carriage 3 and is rovided with a series of (in this instance t ee) operating-faces, each carr ing a blank-holding chuck 30 and adapte to be 'successively brouglht into registration with the matrix 5. As s own in the drawings, this turret is mounted u on a shaft 31 and is provided with a ratchet-wheel 32,fthe teeth of which are adapted to be engaged by a toothed rack 33, which is adjustably secured by suitable bolts 34 to the upper portion of the frame 1 of the machine. This toothed rack 30 is preferably made of spring metal of suflicient resiliency to permit its teeth to ride over the teeth of the ratchet-wheel 32 during the forward movement of the carriage 3 toward the matrix and to cause the teeth of said rack to engage the teeth ofthe ratchet-wheel 32 and rotate the turret 4 one chuck-space during the return of the carriage from its operating to its normal position, as best seen in Figs. 1 and 2.

The toothed end of the rack 33 is, therefore free to yield vertically, while its attaching end is provided with slots 35 for receivving the clamping-screws 34 and permitting proper adjustment of the rack to mesh with the teeth of the ratchet 32 and produce the desired'step-by-step movement of the turret to bring each chuck into exact alinement with the matrix 5. In the use of this rotary turret it is desirable to temporarily lock it in its adjusted position during the impressionmaking operation, and for this purpose each operating-face of the turret is provlded with a transverse recess or notch 36, ada ted to receive one end of a locking-bolt, Wiich in this instance is composed of two sliding boltsections 37 and 38, guided in suitable ways in the carriage 3 and connected by an adjustingscrew 39, having right and left hand threaded ends engaging corresponding threaded sockets in the adjacent ends of the bolt- sections 37 and 38, so that by rotating the screw 39 in one direction or the other the bolt- sections 37 and 38 will be correspondingly drawn together or forced apart for the purpose of bringing the locking-bolt into pro er correlation with its operating-cam, as t e end face 40 of the cam 6, whereby the locking end of the bolt-section 37 is forced into the alined recess 36 of the turret 4 just before or at about the same time that the operating-face of the turret is advanced to the matrix.

The locking-bolt section 38 is provided with a spring-arm 41, having its free end offset longitudinally and terminating against the cam-face 40 of the cam 6, the greater ortion of which is disposed at substantially right angles to the axis of revolution of said cam and equal to about half of its circumference corresponding to the similar ortion 28 of the cam-groove which receives t e roller 8. The spring 41 on the locking-bolt section IOO hel

l l 'cess 36 vunder a yielding tension and compensate'sfor any inequalit in the cam-face 40, againstl which the end o the arm 42 bears.

Itis now obvious that when the carriage 3 and its turret-4 are advanced by the inclinedA cam 28 thev locking- bolt sections 37 and 38 are corres o'ndingl advanced with the carriage unti the rol er 8 begins to enter the annular groove 28, whereupon the cam 40, a

portion of which is inclined longitudinally,

causes a quick forward movement of the sliding 'belt- sections 37 and 38 ,to force the end of the bolt-section 37 into the adjacent recess 36, and owing to the fact that the greater ortion of the cam-face is at substantial y right angles to the axis of rotation of the cam 6 and of substantiallythe same circumferential length as the groove 28 it is evident that the locking-bolt will be held in operative position until the carriage begins to return by the cam-groove 28, acting upon the roller 8, whereupon the sliding lockingbolt is returned to its normal position by a spring-arm 44, which has its free end bearing against a pin on the sliding bolt-section 38, as best seen in Figs. 1, 2, and 4.

The in 45 is interposed between the spring 44 an adjacent portion of the carriage, which latter acting upon said pin serves to move the locking-bolt forward with the carriage but as soon as the carriage reaches the limit of its forward movement, as determined by the cam-groove 28, the locking-bolt is further advanced by the cam 4() against the action of the spring 44, vso as to positively interlock with the recess' 36 in the adjacent face ofthe turret, and as soon as the carriage begins to return by the action of the inclined groove 28 upon the roller 8 the inclined portion ofthe cam-face 40, corresponding to the inclined groove 28, relieves the tension on the spring 44, which immediately acts upon the pin 45 to return the sliding bolt to its normal position, with the pin 45 bearing against the adjacent face of the carriage.

As previously stated, the turret4 is provided with a series of (in this instance three) operating-faces, each of which is provided with a recess or socket 46, in which is inserted a split bushing 47 for receiving one of the chucks 30, ysaid bushing being slightly smaller in its outer dimensions than the socket or recess 46 in which it is inserted to afford a limited adjustment and is held in operative position by suitable adjusting-screws 48, so that the bushings 47 may be adjusted to bring their respective chucks 30 into exact registration with the matrix 5.

Each chuck 30 is therefore frictionally held in place by its respective split bushing 47, which in turn is held in the socket 46 by the adjusting-screws 48, the latter serving best seen in Fig. 3., engages the end of the spring-arm 42 and j.

ving upon its -inclosed chuck.

Each chuck 30 is provided with a central recess 449 for receiving and retaining lone of the t e-blanks', as 50, which is usually place j the impression-making o' erationl of` the viousl placed in another chuck and now broug t Into 'registration As soon as `eachchuck,

sufficient' pressure to leave itsimpression in said blank, and for this purpose the matrix,

- which may be changed at will, isA removably seated in a suitable holder 50-, which in turn is held in a split bushing 5l in a socket 52 in one end of an oscillatoryelement 53. The holder 50 andsplit bushing 51 correspond to the chuck 30 and bushing 47 of theblankholding turret, and the split bushing 51 is clamped upon the holder 50 by suitable adjusting-screws 54.' This oscillatory'member 53 constitutes an important part of my invention and, as shown in Fig. 2, consists of a metal bar'or casting of suitable strength to` resist compression strains to which it is subjected and has oneend, in which the matrix 5 is mounted, provided with opposite toothed segments 56, meshing with companion toothed racks 57, which latter are secured by suitable fastening means, as screws 58, to the vupper portion of the frame 1, while the other end of said oscillatory element 53 is rovided with a curved bearing-face 59, which is seated in a correspondingly curved bearing in the adjacent face of a vertically-reciprocating element 61.

The toothed segments 56 are disposed in the same circular plane concentric with and of substantially the same radius as the curved bearing 59, and therefore thel oscillatory element 53 constitutes a segment of a roller having one side formed with toothed segments meshing with straight vertical racks 5,7, while the other end is supported ink the curved bearing 60 ofthe vertically-sliding element 6,1. f

With the matrix; asiY y hand in the upper-,chuck 30 during I .matrix upon the type-blan which was pre- I,

with its type-blank therein, is advanced into position to receive an impression from the matrix saidmatrix .is'rolled across the face of thel blank with ICO lIO

The pitch-line of the toothed segments 56 a rotary shaft. es, which is journaled in the upper portion of the frame 1 and is provided with ,a driving-pulley 64, which may be con- 63 operates in a suitable slot or recess 65 in the adjacent end of the element 61, said slot but is elongated transversely suflicient to permit the free rotation of the eccentric without effectingV and lateral movement of the sliding element 61, which is guided in suitable/ways in the frame l.

'Each of the toothed racks 57 is preferably made in two sections placed side by side, and each provided with a corresponding-'number each other to take up any incidental wear for p the purpose of preventing loss motion betermeshinr tween the toothed segments 56'and racks 57, the clamping-bolts 58 serving to retain the latter sections in their adjusted position.

In order to relieve the strain upon the inteeth of the segments' 56 and racks 57, I provide the oscillatory members 53 with opposite bearing-faces 55, which are disposed in the same plane as the pitch-line of the segments 56 and bear upon corresponding vertical bearing-faces 66 just inside of the racks 57. This action of the oscillatory member 53 to roll the matrix across the face of the blank for making an impression in the latter takes place `during substantially half a revolution of a cam 6, or while the camgroove 28 is holding the carriage in its advanced position, and when the eccentricshaft 63 is driven by a separate mechanism from that which operates the cam 6 it is evident that the carriage may be heldin its advanced position as long as desired by simply throwing the worm 10 out of mesh with the worm-gear 9, thereby allowing the matrix to be rolled back and forth across the face of the blank as man times as may be necessary to produce the esired impression therein; but under ordinary conditions the rolling action of the matrix and its actuating mechanism and also the action of the cam upon the carriage are continuous, the period of holding the carriage in its advanced positionbeing or,

, dinarily sufficient to allow the matrix to make the desired impression in the blank.

After the matrix has left its impression in the blank registered therewith the inclined portion-of the cam 6 acting upon the roller 8 draws the carria e 3 and turret 4 back away from the matrix, during which operation the toothed rack 33 engages the teeth of the ratchet 32 and rotates the turret one chuckp space, or in this instance one-third of a revoret having a plurality of type-blank ho Immediately upon the withdrawal of the sliding cam-bolt 71, which is actuated against j the action of a spring 72 by a fixed cam 73 as best seen in Figs. 1 and 3.

In substantially all of the sliding elements hereinbefore described I employ suitable gibs and adjusting devices to take up any incidental wear and prevent as far as racticable excessive loss motion.
