TYPE-WRITING MACHINE.
Specification of Letters l atent.
Patented Aug. '7, 1906.
I 1ng-point.
In such machines the ribbon-vibrator is operated in the usual manner by a universal bar, and the latter is operated by all the type-keys,
including the accent key or keys; but each of the latter controls means for preventing the carriage from being fed by the operation of the universal bar, and hence it is practicable by striking one or more accent-keys and then the ordinary type-key to secure proper register or relation of the accent or accents above or below the letter upon the written sheet.
In carrying out my present improvements I mount upon the dog-carrier of the wellknown Underwood type-writing machine an interponent, which under normal conditions serves to transmit movement from the universal .bar to said dog-carrier. To the accent key or keys, however, I connect means for moving said interponent to idle or ineffective position, so that the movement of the universal bar has no effect u on the dog-carrier, and hence, althought 1e ribbon is vibrated to cover the printing-point, still the carriage-dogs are not moved and no feeding of the carriage is effected.
In the accompanying drawings, Figure 1 is a perspective view of my improvements applied'to the carriage-feeding and ribbon-virating mechanisms of an Underwood frontstrike type-writing machine, the parts being all shownin normal position. Fig.2 is afragmentary perspective view illustrating 'the manner in which an accent-key Withdraws the interponent to permit movement of the universal bar without operating the dog-carrier. Fig. 3 is afront'view of a portion of a dog-carrier, showing a slide mounted thereon and carrying a yielding interponent, the parts being shown in normal position. 4 is a sectional elevation taken from front to rear and illustrating details of the interponent mech anism, the parts being shown in full lines in normal position and in dotted lines with the interponent withdrawn to idle position.
An accent-typel is fixed upon a type har 2, mounted upon a fulcrum-rod 3 and engaged by a bell-crank 4, the latter connected to a lever 5, having an accent-key 6 and pivoted at its rear end at 7. The levers and bellcranks for the ordinary types are indicated at 8 and 9, respectively. A depression of any key carries down its lever and vibrates th'e bell-crank forwardly, thereby throwing the type bar rearwardly, the type striking through a ribbon 10 against the front side of a platen. (Not shown.)
Each of the series of type-bars has a heel 1 1,which strikes a curved universal bar 12 and moves the same rearwardly, the universal bar being fixed upon a horizontal table or frame 13, which in said machine is suitably guided for rearward and forward movements. Upon said frame is usually fixed a slotted actuator 14, which engages a wrist 15, provided upon a short arm 16 of a lever 17, whereby the latter is caused to carry u and down a vibrator 18, through which is t readed the ribbon 10. The ribbon is vibrated at the actuation of all the type-keys, including the accent-keys.
Said universal-bar frame is also utilized to effect the feeding-of the paper-carriage, the
latter, including a rack 19, meshingwith a inj ion 20, connected to an escapement-whee 21 with which cooperate the usual spacing and det'ent-dogs 22 and 23, said dogs mounted upon an upright rock-arm or carrier 24:. The backward movement of said can ier is effected in this instance by means of an interp nent comprising a plate 25, having at its upp r end a head 26. One side of the latter re es the im act of a tappet 27, mounted upon the.
rear e ge of the universal-bar frame 13, and the other side is in contact with a screw or adjustable abutment 28, threadedinto the upper portion ofthe dog-carrier 24, thereby .ments of the carria ge. Said interponentplate 18 secured at its pvver ends by means of screws 29, upon a vertical slide 30, mounted upon the dgcarrier. The plate is yieldmg and presses lightly against the screw 28, the latter having a rounded end to engage the head 26.
The slide is provided with a projection 31, whereby it may be ulled down, this movement being. effected y an arm 32, hav mg a lip 33 normally standing over said projection 31, said arm being fixed upon a rockshaft 34, suitably mounted in the framework of the machine and provided, near its righthand end, with operating-arms 35, having pins 36 engaged by slots 37, formed vertically in the upper ends of links 38 connected to of a universal bar operable the accent-type key-levers 5.
When any ordinary key-lever 8 is depressed, its type-bar is swung up until the universal bag is operated, so that the ribbon is vibrated, and the dog-carrier is also swung backward by means of the interponent 26; but when any accent-key 6 .is depressed its link 38 is drawn down, vibrating'the arm 35,
and rocking the shaft 34 and arm 32, the lip 33 on the latter carrying down the projection and slide 3'), a: d hence withdrawing the interponent 26, so that the movement of the universal b ar 13 is ineffective to o erate the dog-carrier 24. The rovisiono the slots 37 in the links 38 enab eseither link to rock .the' shaft 34'indepen'dently of the other. A
counterweight 39 or other means may be provided for returning said shaft to normal position. A spring 40, provided upon the dog-carrier, engages an ear 4L upon the slide 30 to lift the latt to normal position independently of the eye 5. The slide 30 is guided partly by means of a vertical sl'0t42, Which-en ages a screw 43, having a s uare collar-or reeper' 44-, partly by the hea 26,
which works in a slot 45, formed in the front face of the dog-rocker.
Variations may be resorted to within the scope of my invention, particularly in the construction and -operation of the,interpo-- nent, which need not in all cases be mounted upon the dog carrier or actuator, and portrons of my improvements may be used with out others. 7
