TYPE-WRITIN G MACHINE.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed July 21, 1905. Serial No. 270,645.

To all whom it may concern:

Be it known that I, \VAL 'ER J. BARRON, a citizen of the United States, and resident of the-borough of Brooklyn, city of New York, in the countyof Kings and State of New York, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

.My invention relates to printing point indicators forv typewriting machines and one object of the invention is. to provide a simple and ellicient indicating means including a printing point indicator which is automatically moved away from the indicating position at. each printing operation.

A further object of my invention is to )rovide means for throwing the. riotin point indicator out of operation at will.

A still. further object of my invention is to provide an automatically actuated printing point indicator with means cooperating with a. scale to indicate the position of the can riage with reference to the printing point.

To the above and other ends which will. hereinafter appear. my invention consists in the features of construction, arrangements of parts and con'ibinations of devices to be hereinafter described and more particularly pointed out in the appended claims.

In the accoi'npanying drawings, wherein like reference characters indicate correspending parts in the various views, F igure 1' is a fragmentary front elevation of sullicient number of parts of one form of typewriting machines to illustrate my invention in its ap 'ilicatiou thereto. Fig.2 is an enlarged detail vertical sectional view showing the printing point indicator and the associated mechani m. Fig. 2 is an enlarged detail front elevation of a portion of the same. Fig -1t is a detail side elevation of the retaining device or latch for locking the printing point indicator out of operation. Fig. 5 is a detail front elevation of the printing point indicator. Fig. (3 is a detailplan or face view of the blank from which the printing point indicator is formed.

I have shown my invention applied to a Monarch machine but it should be under stood that the invention may be applied to ,various forms of typewriting machines:

The frame 1 of the machine has key le-- vers 2 fulcrumed therein inthe usual manner and cooperating with the printing intop plate 3 of the machine is a carriage 4 which is adapted to travel from side to side of the machine and carries a platen Extending beneath the various key levers 2 is a universal bar (3 which is carried by a' universal bar frame 7 pivoted in the base of the machine at the pivotal center 8. A rearwardly extending arm 9 on the universal bar frame is pivoted at 10 to an upwardly extending link 11 which is forked at its upper end 12 for cooperation with an automatically actuated eccentric 13 that effects a fore and aft movement of the link 11 to move a laterally projecting pin 14: thereon in a slot 15 that extends longitudinally of the vibrator actuating lever 16 so that the pin 1% may be automatically mo ved nearer to or further from the fulcrum 17 of the v1- brator actuating lever, thus giving different extents of throw from the normal position to the vibrator, to effect a transverse feed of the ribbon while it is fed longitudinally. This mechanism is essentially the same as that illustrated in the patent to Felbel & Gabrielson No. 703,339, dated June 2l,1902, and fruther description thereof is deemed unnecessary. The forward end of the vibrator actuating lever is forked or bifurcated at 18 where it cooperates with a pivot pin 19 carried by a depending arm 20 on a ribbon vibrator 21. The ribbon vibrator has inwardly bent parallel side edges 2; which are received in grooves in the outer edges of upright arms A On a hxed vibrator guide which is secured in place by screws 25. A printing point indicator 3G is provided with an inwardly bent indicating arm 27 which is, at its indicating end 28, substantially the width of a character to be written on the machine and has an upright line or indicating mark 29 which indicates the exact vertical center of a character written at the printing point. The printing point indicator is pivoted at 30 to a fixed portion of the machine by a headed pivotscrew and an ear or finger 31. projects from the indicator and cooperates with the head of a fixed screw or stop 32 to limit the movement of the indicator to the normal or indicating. position. A contractile spring 33' is secured at one end to the tinger 31 on the indicator and at its opposite end to a 'screw 34 on a fixed portion of the machine to restore the indicator to the normal position. A cam strumentaliti'es to actuate them. Above the t 35 is provided on one sideedge of the indicator for cooperation with the forward end of the ribbon vibrator actuating lever 16,, as illustrated in full lines in Fig. 3,

A spring pressed latch 36 is pivoted at 37 to a bracket plate 38 secured by screws 39 to the segment 40. This spring pressed lock or latch has a finger piece 41 extending therefrom, and a pivoted locking member 42, which is in the form ofa yoke, is pivoted at 43 to the bracket plate B8 so that it may be turned from the full to the dotted line position shown in Fig. t. The bent end 4:4 of

the latch or locking device is adapted to cowhere the hook-like end 44 operate with the printing point indicator at L5 as clearly represented in Fig. 3 in order to lock the indicator in the dotted line position shown in Fig. 3 and to maintain said indicator in the non-indicating position and in a position where the, cam 35 thereon is held out of the path of the vibrator actuating lever 16 so as not to be affected thereby and so as not to affect the operation of the actuating lever 16 and the ribbon vibrator controlled thereby. hen the operator desires to use the printing-point indicator it is merely necessary to swing the locking device or-bail 4.2 over the finger piece 41 while the same is maintained depressed, thereby locking the latch 36 against the tension of its spring and maintaining it in a position thereof cannot engage the indicator.

A platen or carriage scale i6 is carried by and travels with the carriage and is exposed to the view of the operator between the arms 24 and the fixed vibrator guide. The printing point indicator carries an index which comprises two

pointers

47 and 48. Then the printing point indicator is in the normal or indicating position the-pointer lS will register with an index on the scale to designate the position of the carriage relatively to the printing oint, whereas when the printing point indicator is in the nonindicating position the pointer {l7 will be moved to a point where it will occupy the same position as that formerly occupied by the'pointer 4:8 and will operate with the scale L6 to indicate the position ofthe carriage with reference to the printing point. From this it will beseen that the position of the carriage may be readily determined by the

pointers

47 and 48, whether the printing point indicator be in the indicating or the non-indicating position.

In the operation of the device a depression of a finger key 2 will effect a depres sion of the associate key lever. 2, thereby moving the type bar controlled-by said key lever to the printing position. This same depression of the key lever effects a downward movement of the universal bar and through the link 11 and lever 16, will cause the ribbon vibrator to be elevated, thus interposing the ribbon in the path of the type bar which is approaching the print- As the forward end of the ribbon vlbrator actuating lever 16 is eIemg position.

vated, it is brought into cotiperation with the cam 35 on the printing polnt indicator,

thus moving it from the full to the dotted line position shown in Fig. 3. When pres= sure on the finger key is released the type bar will be restored to its normal position in the usual manner and the universal bar will be elevated by its restoring spring (not shown), thereby causing the ribbon vibrator tomove back to the normal position and the printing point indicator will be restored to its normal or indicating position shown in full lines in Fig. 3 where it will register with the printing point. Should the operator desire to dispense with the use of the printing point indicator, it is merely necessary to move the indicator from the full to the dotted line position shown. in Fig. 3, by hand or otherwise, and effect an engagement between the locking device 36 and the printing point indicator to lock it in the abnormal or non-indicating position.

Various changes may be made in the connation or a printing point indicator, means for automatically moving the indicator to and from the indicating position at each printing operation, and alatch 'for locking the'indlcator out of operation.
