INKING DEVICE FOR TYPEWRITERS Filed March 17, 1948 2 SHEETSSHEET 2 ATTORNEY Patented June 10, 1952 UNITED STATES PATENT? OFFlCE Enrique Cerceau, Cordoba, Argentina Application March 17, 1948, Serial No. 15,409
The present invention is concerned with improvements in typewriters, and the chief object is to provide a typewriter with typeholders which are jointed at the ends of the corresponding supporting arms.
Another object of the present invention is to provide typeholders with means capable of bringing about the rotation of same, from an end position which corresponds to an inking, roller, to a second position corresponding to a cylinder or platen. I
A further object of the invention is to equip a typewriter with an inking roller divided into a plurality of sections, so that each section may rotate independently in the inside of a receptacle containing ink or similar marking fluid.
Other objects and advantages of the present invention will appear from the detailed description hereinafter set forth.
In order that the invention may be more clearlyunderstood there will now be described with reference to the accompanying drawings, a preferred embodiment thereof which is given by way of example only and not by way of limitation.
In the drawings:
Fig. 1 is a schematic representation of a machine including the inherent characteristics of the invention;
Fig. 2 illustrates a mechanism connected to one typeholder, which is shown in its two extreme positions;
Fig. 3 is a schematic representation of a typeholder in its lower final position, in which a type carried thereby lies in contact with an inking roller;
' Fig. 4 is a similar view of the typeholder in which it is shown in its upper position with a type lying in contact with the cylinder or platen, and
Fig. 5 is a section taken along line A-A of Fig. 3.
The machine, in its general construction and as shown in Fig. 1, is essentially constituted of the following means:
(a) Type elements associated with means arranged to bring about actuation of the same;
(b) Type-inking means;
() Cylinder or platen.
As illustrated in Figs. 2 to 5, the writing element is constituted by a typeholder I, which forms an integral part of a projection 2, by means of which the same is rotatably disposed at the bifurcated end 3 of an arm 4.
The projection 2 is pivoted on a pin which I passes through both arms of the bifurcated end 3,. and is provided with an opening 6 in which acts a trigger I, this latter having an integral i 2 I sliding member 8, conveniently located in a guide formed in the corresponding arm 4, as shown in Figs. 3to 5." v
Fig. 2 shows one method by means of which the arm 4 may be moved, in which said arm is pivoted at an intermediate point of its length on a pivot pin 9, which forms an integral part of the frame of the machine.
In turn, the said arm 4 has at the opposite end to the typeholder I, a slot ill in which is disposed a small stem I I, said stem being solid with projection I2 which forms an integral part of an arm [3, which is pivoted, at one of its ends, on a shaft 14, while at the opposite end is applied the key I 5 for the manual movement of the type.
0n pressing said key the arm 4 passes from the position represented by the full line in Fig. 2, to that indicated by the dotted line in the same figure, thus producing angular rotation of the typeholder around pin 5.
Said angular rotation is produced as a result When the sliding member 8 operates on the abutment I6, the typeholder I comes into contact with the platen, which has been indicated in Figs.
2 and 4 by the reference numeral 2 I.
As what is represented and described is'given as merely an explanatory example and not'by way of limitation it is evident that modifications of construction and detail may be introduced without departing from that which, as a characteristic, is claimed in the claims which follow this description.
