The actuating lever I34 may be in the form of a bell-crank, pivoted on a shaft I35 suitably secured 45 to the machine-frame. The rearwardly extend ing arm I38 is also secured to shaft I35 and is pivotally connected by means of a pin I31 and link I38 to a cam-roller I39 mounted on an arm I40, which is pivoted at I4I to the machine-bed 18. 50 Cam I42 mounted on shaft 94 so as to rotate with the sprocket 93 imparts a substantially ver tical motion to link I38, which is translated into a horizontal movement of detent-bar I28. The cam I42 engages the roller I39 immediately 55 prior to the engagement of roller IIO with a slot of the Geneva follower II2, so as to withdraw the detent-bar I28, in opposition to spring I3I, prior to and during the rotation of the die-bed II8 to the next operating station. When the next oper 60 ating station is reached, the engagement of cam I 42 and roller I39 will terminate, and spring I3I will be free to drive the detent-bar I28 into en gagement with a slot, as I21°, so as to prevent the further rotation of the die-bed during the rolling process. ’ ' As indicated on Figure 12, the bottom of the die ~ - ' ' A pair of rollers I82 and- I83 having toothed extermities I84, I85 and I88,.I81, mesh with each other and have their curved surfaces in contact.

The toothed‘bearings I88 and I89 of the ' lower roller mesh with the rack-teeth of the sup ports I59 and I80. 49 Because the rollers aregiven only a limited rotation, the front and rear surfaces can be planar, as shown in Figure 13.

In manufacturing a set of typewriter-types, each type having a head formed with a type-char acter, and also having a single thin shank-?n, the shank-?ns severally being disposed, substan types; the method of forming the type-charac tially as set forth, at different angles with a com 15 mon printing-plane for the types; the method in which uniform type-blanks, such as 12, are used ter on each type and at the same time establish being in the form of a rod having a longitudinal ing the companion shank-angle, said method in cluding operating upon a type-blank, having such shank, with a type-character-forming device while holding said blank in blank-receiving means arranged in a type-forming press to ?x the shank at a certain angle to the character-form ing device, the several certain angles at which the shanks of the blanks for the set of types are ?xed relativelyto the character-forming device being the same as the several different angles of the type-shanks with said common printing 30 shank at a certain angle to said stamp, said die also being arranged and used as a matrix into which the stock is molded, by the character forming ‘pressure of said stamp, to produce said plane. 3. In manufacturing a set of typewriter-types, each type having a face formed with a type character, and also having a shank attachable to a type-carrier, the shanks severally being dis posed, substantially as set forth, at different angles with a common printing-plane for the types; the method of forming the type-charac ters for the set of types and at the same time es tablishing, for each type, the companion shank angle, said method including operating upon to produce the diverse types of the set, each blank thicksection that constitutes stock for the head, 20 the remainder of the rod being in the thin form of said shank-?n, said method including operat ing upon the stock of each blank with a type character-forming stamp while holding said blank with said shank-?n ?xed at a certain angle 25 to said stamp, the several certain angles by which the shank-?ns of the blanks for the set of types are ?xed relatively to the stamp being the same as the several different angles of the type-shanks 80 with said common printing-plane. 7. The method of producing type-blanks for a set of typewriter-types of the character de scribed, each type having an elongated stick on one longitudinal side of which the type-character is formed, and also having a single shank-form ing ?n appendant \as a thin ?ange along the under side of said stick, said method being di rected to ?nishing the ?n to its final‘ thickness while producing the blank, and therefore includ ing rolling or drawing type-blank material into a rod of L-shaped cross-section by suitable means type-blanks, having such shanks, with type-char devised to make one leg of the L of the ?nished acter-forming devices while holding each blank thin cross-section dimension of said ?n, and to in a type-blank receiver arranged to ?x the shank of that blank at a certain angle to the char acter-forming device, said method including the use of a set of different angle-establishing type bla'nk-receivers, one type-blank receiver for each of the said di?‘erent angles. 4. The method as set forth in claim 3, the set 50 of types including certain pairs, in that the in dividual types of a pair have their shanks dis posed at the same angle to said printing-plane but in opposite directions from the middle of the set of types, one blank-receiver being used for 55 each such pair of types and being used reversibly to point the shanks of that pair in said opposite _ directions. 5. In manufacturing a set of typewriter types, each type having a head formed with a type character and also having a single shank-form to ing ?n, the shanks severally being disposed, sub stantially as set forth, at di?erent angles with a common printing-plane for the types, each type also having underneath said head a pronounced 65 boss-formation, such as 3!, It: the method of forming said types from a set of blanks, each blank having stock for the head and boss-forma tion, and also having such shank-?n appendant to said stock.'said method including workins said stockv of a blank for each type with a 10 upon character-forming stamp while holding the blank in a blank-receiving die arranged to fix said make the other leg of the L as a thickened stock, such as ‘Ill, workable by means of stick and type 46 character-forming pressure dies while the ?n is held at a certain angle in a die, the ?ns of the blanks for the several types of said set being held at diverse angles, as set forth. 8. The method of producing type-blanks for a set of typewriter-types of the character described, each type having an elongated stick on one lon gitudinal side of which the type-character is formed, and also having a single shank-forming ?n appendant as a thin ?ange along the under 55 side of said stick, said method being directed to ?nishing the ?n to its ?nal thickness while pro ducing the blank, and therefore including roll ing or drawing type-blank material into a rod of L-shaped cross-section by suitable means de vised to make one leg of the L of the ?nished thin cross-section dimension of said ?n, and to make the other leg of the L as a thickened stock, such as ‘ll, workable by means of stick and type-char acter-forming pressure dies while the ?n is held at a certain angle in a die, the ?ns of the'blanks for the several types of said set being held at di verse- angles, as set forth, said rod being rolled or drawn to a length affording a multiplicity of the type-blanks, said method including cutting up the rod of said length into said type-blanks. ‘ - EDWIN THORELL.
