Specification of Letters Patent. Patented J l 19 1910 Application filed March 6, 1905'. Serial No. 248,570.

{Tole whom it may concern:

''B it; known that I, VALTER J. BARnoN,

n'of the United States, and resident of e borough of Brooklyn, city of New York,

in the county of New 'York and State of New York, .have invented certain new and useful Improvements in Type-VVriting Ma chines, of which the following is a specification.

My invention relates to typewriting machinesand more particularly to indicating mechanism therefor and by which an 1nd1- cator maybe automatically moved to the indicating position and may be permitted to more away from the indicating position when desired, without disconnecting the parts, and while the platen remains in the swung-back position to expose the writing.

To the above and other ends, which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combination of devices to be hereinafter described and claimed.

In the accompanying drawings, wherein like reference characters indicate corre 'sponding parts in the various views, Figure 1 is a fragmentary vertical sectional vlew through the upper portion of a bottom-strike typewriting machine showing one .form of construction embodying my invention. Fig. 2 is a fragmentary plan view showing the indicator andj-a portion ofthe actuating means therefor. Fig. 3 is a View corresponding in part to Fig. 1 except that the platen is shown swung back and with the prlnt ing point indicator in the indlcatlng position, the platen being swung back from the lower case position. Fig. 4 is a like view of the same showing the platen swung back from the upper case position; Fig. 5 1s a View corresponding to Fig. 4, except that the 1ndioator is shown lowered to the normal position byaslight forward movement of the 'pla ten framef; Fig. isa fragmentary front I the l laten swung back to expose thewriting an the prmting'point elevation, showin fridic'ator'in thindica'ting position. I {have illustrated my 'inventionin the present instanceapplieditoa No. 6 Remington machine, though it should be understood that the inventionlniay be appliedto various other, forms of mach nes and that the construction may be changed accordingly; 1 I

The top plate 1 of the machine suppprts the? usual =lugs er risers 2 for a traverse 5. A platen frame 6 is pivoted, by pivotpins 7, to links or arms 8 that project from a rod or rock shaft 9 pivoted at its ends in the carnage truck 5. Screw stops 10 and 11 extend in opposite directions through lugs 12 carriedby the truck and cooperate with :the pivot pins .7 to limitthe fore and an movement of the platen frame when it is shifted to shift the platen from one case position to anothef'." The platen frame carries a platen 18 and the usual paper apron let, platen scale 15 and feed rollers 16 and 17. The forward end of the platen frame carries a roller 18 that cooperates with a shift rail 19 and by which the platen is shifted for upper and lower casewriting and a handle -20 is provided to swing the platen frame hack on its pivots.

A bracket plate 21 may be secured place in the rear of the platen by two screws is bifurcated at its forward end, and the o arms 2 1 of the bifurcated portion are providedwith upwardly extending arms 24 havlng bearings for a pivot pin 25 of a printing point indicator 26, that in the present instance has parallel sides and ends with a central opening therein through which the types strike, and the outer of the indicator has. a pointer 27 projecting outwardly therefrom to register with the printing point and a pointer 28 projecting inwardly therefrom to register with the indices on the .platenscale .15, a1l as will hereinafter more clearly appear. The prlnt ing point indicator is therefore pivoted in the rear of the platen and in its normal position extends beneath the platen in substantially a horizontal.-plane. A bearing piece 29 extends inwardly from one of the arms 2% to receive. aflheaded screw 30 that constitutes a pivot for a pivoteddevice or pivoted device 31 contacts with a finger 3-1 that is-inte a1 with and projects'rearwardly from the indicator 26 which is supported. 1n lts'lowermost, or normal position, by a pin 35 projecting inwardly from one of the arms 24.

A detachable -two-part collar 36 is mounted to turn freely on a rod 37 of the platen frame near each end thereof and each collar carries a depending arm 38, the arms being connected at their lower ends by a crossbar 39 that extends substantially throughout the length of the platen and cor responds in length substantially to the run of the carriage. The. upper side of each collar 36 is preferably flattenedfor the attachment of one end or arm of a substantially U-shaped leaf spring o'r friction device 40, so that the cross bar, bail or socalled actuator 39,- arms 38 thereof, the sleeves 36 and springs or friction devices 40 are all connected and are adapted to swing together around the bar 37 of the platen frame as a pivot. A segmental-or half round supporting piece 41 is secured by a screw 42 next to each of the collars 36, each piece 41 being slotted at 41 for the reception of the stem of its screw 42 and extending from each 'of the supporting pieces 41 is an outwardly projecting rigid finger or friction device 43 that extends to a position where it will be brought into cooperation with the cooperating friction device ,40 on the actuator when the platen frame is swung back as indicated in Figs. 3, 4 and 6. The screws 42 not only hold the friction devices 4143 in place but afi'ord an adjustment thereof around the rod 37 so fasI-to regulate t-he engagement flof the fric tio'n device. the coiiperating. devices 40.

,. In the operation of the device the platen frame may be swung back from any point in the travel of the carriage and the friction devices 43 which are fixed to and turn wit-h the platen frame will not be brought into contact with the cooperating friction devices 40 on the actuator until the lastf portion of the swinging movement of the-{'pl'aten, and during the first portion of the swinging movement of the platen the indicator will remain at rest in its normal substantially horizontally .disposed position beneath the platen, and the platen frame may, if desired, be turned back to inspect the writing without actuating the indicator. When friction devices 43 are brought into contact with the springs 40 a frictional engagement between the two sets of devices will be established and the bail, bar or actuator 39 will be swung forward, thus vibrating the lever or device 31 against the tension of its spring and the lever 31 cotiperating with the finger 34 will cause the indicator to be automatically moved from the substantially horizontal position to the upright substantially vertical indicating position illustrated in Figs. 3, 4 and 6, whether the platen be swung fromthe upper case position, with pivot pins 7 in contact with the stops 10, as illustrated in Fig. 4, or from the lower case position with the pivot pins in contact with the stops 11, as indicated in Fig. 3. After I be a continued movement of the devices 43 with the platen frame without efi'ecting undue pressure on the indicator, there being merely a relative movement efi'ected between the devices 43 and their cooperating devices 40. The slightest return movement of the platen will, however, suflice to restore the indicator to the normal position while the platen frame is still maintained in an upright position, as indicated, for instance, by a movement of the platen frame from the position shown in Fi 3to that indicated in Fig. 5. Thus the indicator may be readily restored to the normal position beneath the platen where it stands away from the platen to enable an erasure to be readily made with out interference from the indicator, and while the platen is maintained in the swun back position with the writing ex )osed and where-an erasure can be made wit out difiiculty. l urthermore,the indicator can be restored to the normal position without efiecting a disconnection between the platen frame and the indicator so that, if desired, the indicator may immediately be brought to the indicating 1position by a slight backward tilt of the p aten frame. From the foregoin diescription it will be understood thatthe oiinectlons between the indicator and the platen frame constitute differential means or connections whereby the slight forward movement of the platen frame from either of the positions shown in Fi s. 3 or 4 to that indlcated in Fig. 5 is su c ient to return the indicator to the normal position while the platen still remains in the swung back posltion where the writing can be easily inspected and erasures may be made.

From an inspection of Fig. 4 it will be observed that when the indicator is in the indicating position the pointer 27 does not contact with the paper and that the indicator itself rests agalnst the platen scale 15 and that during the swinging movement of platen the pointer will not be brought into contactwith the platen or the paper thereon.

In certain kinds of printing point indicators heretofore devised, and more particularly those which employ springs to automatically move the indicator to the indicating position when the platen is swung back to expose the writlng, considerable difliculty has been encountered by reason the indicator contact-in paper and by the sharp end of the I w en guides or paper feed rollers at the front of, the platen during the swinging of the platen to the normal position and at times interfering with the feed of. the carriage by bear-ing thereon and by coming into contact with the paper feedin devices during the travel of the carriage. hen againconsiderable diflicnlty has been experienced by with the printed matter and blurring te imprint on the ointer engaging the paper and mutilating 1t. 13

the present invention these and other (lliib' culties heretofore encountered in printing point mdicato rs are obv1ated since the indicator remains in the normal position beneath the platen until the platen frame has almost completed its backward swing and is restored to the normal position at the first aortion of the forward swing of the )laten rame and when the indicator is in t e indicating po- 'sition it is prevented from coming into contact with the paper by contacting with the platen scale. While I have described one form of constructionembodying .my invention, it should means'between said platen frame and indicator for placing the indicator under control of the latch frame in the swinging movements t ereof, said connecting means including means by which the connecting means are constantly maintained in cooperative relation with the platen'frame and indicator when the indicator is in the normal or non-indicating position and the platen frame is inaintamed swung back to expose the writing, whereby the indicator may be moved to the normal position or to the indicating position While the platen frame is maintained in the swung back position and without breaking the operative connection between the platen frame and indicator.
