CHARLES J. BOND, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE MONARCH TYPEWRITER COMPANY, OF- SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.
TYPE-WRITING MACHINE.
Specification of Letters Patent.
Patented April 28, 1908.
To all whom it may concern."
Be it known that I, CHARLES J. BOND, citizen of the United States, and resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the followingis a specification.
My invention relates to automatically actuated printing point indicators in which the indicator is actuated at each printing operation to automatically move away from the normal or indicating position-as the type approaches the printing point. r a
The object of my mvention'is to providea simple and eflicient device of the character specified.
A further object of the invention is to pro- :vide such an indicating device, which is ap plicable to existing forms of typewritin machines without .changing the structura featuresof such machines.
' the indicating device and its associated parts, the parts being shown in normal osi- To the above and other ends which will hereinafter appear, my invention consists in the features of. construction, arrangements of parts and combinations of devices to be hereinafter described and claimed.
-In the accompanying drawin s wherein like reference characters md-icate corresponding parts in the various 'views, Figure 1 is a vertical front to rear sectional view of sufficient number of parts of one form of typewriting machine to illustrate my invention audits application theretoi Fig. 2 is a fragmentary etail front elevation of theupper ortion of the machine. Fig. 3 is an en-' arged fragmentary .detail front elevation of tion. Fig. 4 is a like view of the same s owing the parts in abnormal position. Fig. 5 is an enlarged detail rear elevation of the same. Fig. 6 is an enlarged detail perspective view showing the rear side of the mdicatorr' I have shown my invention ap lied to a Monarch machine, though obvious y it may be applied to other forms of typewritmg machines.-
The base 1 of the machine has corner posts 2. extending upwardly therefrom and these posts support'a top plate 3. Key levers 4 are fulcrumed on a fulcrum plate 5 and are provided with theusu'al finger keys 6 and restoring springs 7. An upwardly extending sub-lever 8 is pivoted at 9 to each key lever and the lower end portion thereof is slotted at 10 for cooperation with a fixed fulcrum rod or bar 11 that extends transversely beneath the key levers and is secured at its ends to the base .1 of the machine. The upper end of each sub-lever is pivotally connected at 12 to a forwardly extending link 13 pivoted at its forward end 14 to a type bar 15. Various type bars are-pivoted on a pivot wire 16 carried by the type bar segment 17 to strike upwardly and 'rearwardly to the printing point.
,Extending transversely beneath the various key levers is a universal bar 18, carried by pivotec in a fixed bracket secured to the top A dog rocker restor-' plate ofv the machine. I mg spring 25 is connected at one end to a fixed .part of the machine and at its opposlte end to the rock shaft 24 so as to'restore the dog rocker and its associated parts to normal position. Feed dogs 26 are carried b the 0g rocker and cooperate with a suitable feed rack 27 connected to a carriage (not shown), which carries a platen 28 and travels from side to side of the machine. wardly extending link 29 is connected at its lower end 30 to the rearwardly extending arm 21 of the universal bar frame and is connected at its upper end 31 to aribbon vibrator actuating lever 32, pivoted at 33 to a depending stud 34 secured to the top plate of the machine.
The forward end of the ribbon vibrator actuating lever is bifurcated at 35 for the reception of a pivot 36 which extends across the opening 37in the depending arm 38 of the ribbon vibrator. has inwardly bent parallel side edges 39 which are received inguide grooves 40 of the The ribbon vibrator upwardly extending arms 41 of the ribbon vibrator guide, the latter bein secured to de ending ears on the top plate y screws 42.
A caring bracket 43 1s connected to the ribbon vibrator guide b screws44 and forms a bearmg'for one end 0 a pivot 45, the other 85 An upand to bear on the top of said lever when the forward end. of the latter is elevated. The second arm 48 extends outwardly and has a bent end or finger 49 which extends beneath the fixed ribbon vibrator guid e and cooperates With said fixed part to limit the movement of the indicator towards the normal or indicating osition. The third arm 50 of lhe indicator is ent inwardly at its upper end. and carries or constitutes a printing point indicator, the indicating nose of which is flattened. at 51 and is of a width corresnomln'ig substantially to a character to be written on the machine, as indicated in Fig. 3. An indicating line or mark 52 is provided on the oi the indicator and said line is located at the longitudinal or vertical center or" the later or character imprinted at the printing point when the indicator is in the norm il position, as represented in Fig. 3. The b spring is sccured at one end to a pin 5 on the indicator and at its opposite end to one of the screws 44 which secures the bracket 43 in place.
The tension of this IESiulll'lgflpl'ihg is exerted to normally maintain the indicator in thenormal or indicating position.
Frorn ancxamination of Fig 3, it will be observed that the arm 47' of the indicator is .normally maintained out of contact with the ribbon. vibrator actuating lever 32, so that the weight of the vibrator and its restoring s ring is not'oxcrted against the actuating evicc therefor, but that the lever 32 will reach contact with the arm 47 and will move the indicator to the non-indicating position, shown in Fig. 4, before the type impacts with the platen. An inking ribbon 55 extends fromone spool 56 to the other and is received in guide openings 57 in the ribbon vibrator and is adapted to be led longitudinally therethrough in the usual manner.
In the operation of the device, a depression of a finger key 6-. will cause a depression of the universal bar, there by elevating the forward end of a ribbon vibrator actuating lever to move the vibrator and thus mterposo the ribbonin the path of the type on the type bar iwhich is approaching the printing position,
and which is controlled by the depressed key.
, Before the type bar reaches the printing position the lever 32 will be brought in contact with the arm 47 on the indicator, thus turning it on its pivot to move the indicator from the osition shown in Fig. 3 to that indicated in 4. When the-imprint has been effecte a release of pressure on the linger key will cause the vibrator to be lowered and the indicator will be restored to the normal position. shown in Fig. 3 by its restoring spring, thus clearly indicating the printing point.
What I claim as new and. desire to secure by Letters Patent, isz- 1. In a typowriting machine, the combina tion of a ribbon vibrator, a device for auto matically' actuating said ribbon vibrator at each printing operation and an indicator independent of the vibrator but which cooperates directly with the vibrator actuating device only at the last portion of the'strolite of said device.
2. In a. typewriting machine, the combina tion of a ribbon Vll)1t0l,-fl11 automatically actuated lever for operating said ribbon vibratonend a spring restored pivoted printing point indicator that has an arm which is normally out of contact with said automatically actuated lever but with which said antomatically actuated lever directly cooperates to turn the indicator away from the indicating position when the said lever is actuated to move the vibrator to bring the ribbon to the printing point and at the last portion of the stroke of said lever.
3. In a typewriting machine, the combination of an automatically actuated ribbon vibrator, a lever for actuating said vibrator, and a three-arin lever, one arm constituting a printing point indicator, anothc" arm constituting a member with which said actuating lever cooperates to move the three-arm lover but which is normally out of contact with said actuating lever and the third arm co6pcrating with a fixed portion of the machine to arrest the indicator in the normal or indicatmg position.
4. In a typewritmg machine, the combina- 'tion of an automatically actuated ribbon "is; my
brator, a lever for actuating said vibrator, a three-arm lever, one arm extending inwardly and carrying a printing point indicator, another arm extending i".wardly and constituting a. member with which said actuating lever cooperates to move the thrccarm lever and the third arm extending outwardly and cooperating with a lixcd portion of the machine to arrest the indicator in the normal or indicating position, and a spring .for moving the three-arm lever to the normal position.
in a typewriting machine, the (IUIHlUlIHL' tion of a vertically movable ribbon vibrator, a fixed guide on which said vibrator slides, a horizontally disposed lever which extends fore and aft of the machine for automatically actuating said vibrator, and a spring restored printing point indicator pivoted to said guide and having an arm on which so id lover bears, so that the indicator will be moved from and to the indicating position by an actuation of the lever.
6. In a typewriting machine, the combination of a ribbon vibrator, automatically ac printing point, the other arm raeav s t'ua'ted ribbon vibrator-operating means, and a spring restored angle lever pivoted to a fixed portion of themachine and having one arm that is adapted to register with the of said lever extending into the pathof the vibrator operatingmeans so as to be actuated thereby but normally out of contact therewith so that the first portion of the movement ofthe vibrator operating means may take place indepenkb ently of the angle lever. r
7. In a ty' ewriting' machine, the combina-' tion of a ribbon vibrator, actuating means therefor, and a printing point indicator that is normally disconnected from said vibratoroperating means but is operated thereby at the last portion of the stroke of said vibrator operating means.
v 8. In a tygewriting machine, the combinameans, the actuation of the vibrator at the first portion of the movement thereof being entirelyindependent of the indicator but the vibrator actuating means cooperating With the indicator at thelastportion 0f the stroke of the vibrator tomove the indicator away from the indicating position.
