ORIENTAL TYPE-XVRITER.

Specification of Letters Patent.

Patented Dec. 6', 1918.

Application filed December 15, 1909. Serial No. 533,132.

To all whom it may concern: Be it known that I, SAMUEL A. H innrson, a citizen of the United States, residing in Brooklyn, in the county of Kings and Stateof New York, have invented certain new and useful Improvements in Oriental Type- WVriters, of which the following is a spec1fication.

This invention has for its object to provide' a typewriting machine in which the relative movement of the platen or paper support, and of the typebar or member carrying the type that print on the paper on the platen will be effected by intermittent advances in one direction by a certain adjustment, and by certain diti'erent. adjustment the same operating device will cause the relativeadvancement ofthe two members to be reversed whereby the feed of the member that is advanced is in the opposite direction. By this means the typebar or type-carrying mechanism can carry two or more different alphabets, one of which such as the English is printed from left to right on the paper, while as a result of said adjustment and shifting of the typebar to bring another alphabet to operative position,

the printing willread in the reverse direction from right to left; as for instance the Hebrew language.

In the accompanying drawing illustrating one embodiment of my invention Figure 1 is aside elevation. 4 Fig. 2 is a plan view. Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4 shows enlarged a fragment of the index bar. F ig. 5 shows enlarged a fragment of the multiple type bar. Fig. 6 is a section on the line 66 of Fig. 2. Fig. 7 is an end elevation enlarged of the advance mechanism. Fig. 8 is an end view of the part shown in Fig. 7. Fig. 9 is a fragmentary view of the actuating dogs shown in Fig. 7 but in the reverse position.

The device is shown as comprising a suitable base B havingmounted thereon a standard 2 carrying a head 3. Onopposite sides of the head are hinge portions 4 and 5 inwhich swing arms 6 and 7 rigidly secured to the typebar cradle 8. A carriage denoted generally by 9 reciprocates in a guideway 10 on the base in a path extending at right angles to the axis 'of the cradle 8 as indicated in Fig. 2. This carriage has

bearings

11 and 12 at its respectiveends in which swings the roller or 'pljaten 13 for carrying the paper to be engaged by the typebar 14 that turns in

bearings

15 and 15 in the ends of the cradle 8. The cradle has an opening 16 in its bottom at the middle portion into i which opening projects the type 17 on the typebar, when the arms and cradle are swung downward to engage the platen or sheet thereon. The typebar is shown as havmg three sets of

alphabets

17, 18 and 19, the

set 18 being the English language, 17 the Hebrew language and 19 may be the upper case English.

An index bar 20 is mounted to turn in

lugs

21 and 22 on a plate 23 carried by the head 3 which plate is shown provided with notches 24 each registering with a character on the index bar. These characters are spaced on the index bar corresponding to the type on the typebar 17. The typebar turns in

lugs

25 and 26 at the ends of a plate 27. whose opposite edges slide in slots 29 nd 30 in the cradle 8. A suitable handle 31 is securedto the plate 27 and carries an index 32 arranged toregister with'and enter one of the notches 24 in the plate 23 .on the head of the frame. l/Vhen-this typebar is shifted under the cradle to register with the notch corresponding to any desired-character, the same character on the typebar-'17 will, from this endwise movement of the typebar, be brought to position to engage pointer 32 opposite the desired letter. The.

same handle is used for swinging the typebar frame downward and the 111(l8X w1ll thereupon enter the notch that will serve to 10C properly position the typebar endwise to.

causethe type to be accurately positioned for engagement with the paper on the platen. A spring 33 on the plate 27 engages the flat faces of the typebar adjacent the several alphabets to accurately position the type when the baris turned whereby the type will be properly presented at the opening for engaging the platen. Also a. spring 34 on the plate. engages fiat faohs on the in deii bar to cause ittobe held in adjusted upon adjustment I means the same operation of the lever Wlll platen,

- one positions. A suitable spring on the standard 2 engages the arm 7 to normally retain the swinging cradle with the typebar 1n the elevated position and returns it when depressed. The arm may have a lug 36:engaging the head to limit the upward swing efilected by the spring 35.

The platen 13 is provided with any suitable pa er retaining device such as a spring plate 3. for pressing the paper against the and it may be turned by a head 38 to line space the sheet. Any suitable means may be also provided forturning the platen. such as a lever 39 carrying a dog 40 thatv will engage suitable teeth in the platen spindle to advance the'platen a unit distance to write a new line. The platen is shown as provided with a cutting blade 40 pivoted at end 41 of the platen with the other end normally locked by a pin 42 to press the paper against the platen. I VVhendesired the paper can be pressed against this blade and the part printed upon can be severed. The plate can be swung outward on its pivot 41 by removing the pin 42 to remove the paper or for other reasons.

Means are provided for intermittently advancing the platen to produce the proper letter space or word space between each dc prcssion of the 'typebar to ef'fect'the printing of a character. This intermittent advancing movement is eflected by the operation of a suitable lever through connecting means,

which connecting means in one position of adjustment will advance the platen at each operation of the lever in one direction; and of the said connecting result in the intermittent advancement of the platen the same unitdistance, but in the opposite direction, bywhich means the platen can at will be fed to print from left to right, or from right to left. And this adjustment or change is effected by merely shifting a single lever or member. In the construction illustrated an operating lever 42 is pivoted on the base at 43, and has hinged thereto an arm 44 carrying a double pawl 45 pivoted thereon. This pawl has

teeth

46 and 47 that respectively register with or engage

rack bars

48 and 49 mounted on the base B, the arm 44-be'ing drawn .downward to cause such engagement of the pawls by spring 50 between the arm and the the ratchet teeth on the bar 48. Upon release ot the lever the reaction of the spring 50t-hat was extended will cause the lever to be elevated and the arm 44 retracted. The

pawl 46 will powengage the ratchet tooth.

and shift the carriage and platen a unit distance, which is limited by suitable stops for the operating lever. But upon shifting the double pawl 45 from the position of Fig. 8 to thatof Fig. 9, the pawl 46 will be thrown out of position for engagement with its rack bar and the other pawl 47 will be swung to position for engagement with its rack bar 49. Upon now depressing. the lever 42, the

pawl 47 being advanced by the arm 44 will positively actuate the rack bar that is mounted on the carriage to actuate the carriage a 'unit distance. And when the lever is released and elevated and the arm 44 retract ed, this pawl 47 ,will ride free over the rack bar. Comparing this operation with the previous operation described with reference to the parts adjusted as shown in Fig. 7 it will be seen that the rack bar is'advanced when the arm 44 moves in the opposite direc tion to that in which the arm 44 moves to ad vance the rack bar 48. .Thercfore with this adjustment the carriage will be intermittently advanced in-the opposite direction; and this reversal of carriage movementis 'efiected by the same movement or operation of the actuating lever, 42, being caused merely by the swinging of the double pawl member, without any other adjustment or shifting of parts. A lever 53 is shown pivoted on the arm 44 and connected by linlt 54 with an eye 55 on the double pawl 45, whereby the swinging of this lever 53 will shift the double p'awl to the positions of operation as just explained. When it is de: sired to release the carriage from the actuate ing ratchets, the arm 44 is simply elevated when the carriage can be moved freely in both directions. 1

Each time the lever 42 is depressed the carriage will be spaced for one characten'but means are shown for causing the operation of this lever by the depression of the typebar to effect the printing operation. This is done by an arm 57 depending from the cradle 8 that engages the arm 42. The pin 58 is engaged by the extremity of the arm 42 to limit its depressing movement. And

ited by the upward swing of the typebar cradle and frame through the arm 57;

A bell 60 is provided on the frame and a swinging hammer 61 engages the bell when tripped. An arm 62 on 'theh'ammer 61 is ,engaged by the bent end 63 of a bar fast to the carriage.

. the upward movement oft'he arm 42 is lim- ;"-Having thus described my invention, 1
