Application filed Octoberl, 1910. Serial No. 587,221.

To all whom it may concern:

Be it known that I, HERBERT H. STEELE, a citizen of the United States, and resident of Marcellus, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type Writing Machines, of which the following in a specification.

My invention relates to typewriting machines and ,more particularly' to line spaeing mechanism. n

The main object of theinvention is'to provide simiple and efficient means for effecting a line spacing of the platen in a machine in vwhich the carriage receives its letter feed movement from left to right, and is returned tothe left to begin a new line of writing', aseismthc case in. writing Arabic or Hebrew characters.

A further object of my invention is to provide such a construct-ion in which pressure applied to al finger piece from right to left is edective to produce a line spacing movement of the platen and also to move the carriage from right to left.

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 particularly pointed out in the appended claims.

`In the accompanying drawings, wherein like reference characters indicate corresponding parts in the various views, Figure l is a side elevation with parts in section of a carriagel of a typewriting machine embodying my invention. Fig. 2 is a fragmentary detail front elevation showing aportion of the carriage and the line spacing devices. Figs. 3 and 4 are det-ail top plan views of parts of the line spacing mechanism to be hereinafter described. Fig. 5 is a detail fragmentary perspective viewshowing a' portion of the line spacingmechanism. Fig. 6 is la diagrammatic front elevation showing some of the parts represented in F ig. 2, the parts being shown in the positions they assume at the end ,ofr an actuation ofthe linespaci-ng mechanism. Fig. 7 is afragmentary -end elevation, with parts in section, of Ithe carrage and'other parts and a portion ofthe escapement mechanism. Fig. S is an enlarged. detail fragmentary rear elevation showing a portion of the escapement mechanism.

I lhave. shown my invention in the present instance embodied in a typewriting machine resembling the Monarch machine. It should be understood, however, that in the present instance the construction is such that the carri-age is moved from left to right under the power employed to move it, and under the step-byestep control thereof elected by suitable'letter space mechanism, such, for instance, as that disclosed in my application, Serial No. 588,682, filed October 24th, 1910; and that a free movementot' the carriage from right to left is afforded to begin a new line of writing. I have not deemed it necessary to show the mechanism for controlling the feed of the carriage in its entirety since any suitable mechanism may be employed for this purpose so long as it ali'ords'a free return movement of the carriage `trom right to left.

The carriage comprises end VAplates 1, united by a rear cross bar. including oppositely grooved carriage rails 2 which receive anti-friction balls or rollers S: which rollers are likewise received in oppositely grooved fixed carriage rails 4 that are carried by brackets secured to the top plate of the machine. I have shown only so much of the escapement mechanism as may be necessary lto indicate that the carriage is restrained against movement from left to right and is freeA to be moved from right to left to begin a new line. From an inspection of the parts represented in Figs. 7 and 8, it will be understood that the feed rack a, the coperating feed pinion, the escapement wheel, the backing pawl b. the coperative ratchet wheel c, and the feed dogs are all of the usual Monarch construction except that the parts have a reverse arrangement from that ordinarily' employed so as to afford a stepby-step letter space movement ot the carriage trom left to right and a free movement from right to left. Thus when pressure is applied toreturn the carriage to the left, 0r in the direction ot' the arrow fr. as the parts ein shown in Fig. S, the pawl will rotate,

STATES PATENT FFQE; I

' rection Aopposite to t in the 'direction of the arrow a, with the escapement Wheel shaft and the housing'connected therewith, thereby carrying the pawl b freely around the teeth of the vratchet wheel c which is connected with the escapement wheel. This enables a free movement -of the carriage from,gright to left to be 5 extendsthrough bearing openings in the end plates 1 and supports a rotative cylindrical platen 6. The left-hand end of the platen is provided with a line spacing ratchet wheel 7, having line spacing crown teeth 8 thereon, as in the Monarch ,machine The left-hand end plate l of the carriage is provided with a bearing 9 which receives a bearing sleeve. or support 10 therein. A

'depending arm 11 is iixed to the sleeve 10 in any suit-able manner, and the lower end portion of the arm 11 bears against the forward face of the left-hand end plate and is apertured to receive a shoulder 12, formed on a bearing spindle 13. The inner end of the bearing spindle is threaded at 14 and is received in a tapped opening in the left-hand end plate of the carriage. An octagonal engaging portion 15 is formed on the spindle 13 and is adapted to bear against the outer face of the arm 11, so as to bind it against the forward face of the left-hand' end plate of the carriage; the octagonal engaging portion 15 constituting means by which the spindle may be turned to thread it into place in the tapped opening in the end plate.` It will thus be understood that the spindle 13 is rigidly secured to the end plate 'and engages the lower end of the arm 11 and holds it against movement, so as to hold the sleeve 10 against movement.

The rear end of the sleeve 10 is cutaway at 16 to receive an inwardly projecting stud 17 on a vcarrier or crank arm 18 which surrounds the sleeve 10 that is supported thereon. The arm or carrier 18 is apertured at 19 to receive a pivot 2O of a line spacing pawl 2,1, which co erates with the teeth 8 of the line spacing heel during the downward movement of the pawl; the pawl engaging the teeth .in the' rear of the platen shaft. i l

A rock shaft 22, which extends f Ore andl aft of the machine, is received in the bearing sleeve`10. and has a hub 23 fixed ,to the forward end thereofl by a pin 24. This hub has acrank arm 25 extending therefromV and a pivot 26 connects this crank arm with. a

link 27. The opposite end of the link 27 is I which coperates with a corresponding' clutch section 32, on a sleeve or hollow rock shaft 33 provided with an upwardly extend ing linger piece 34. The two members 30 and 33 are received and turn on a spindle 13, and are held against displacement therefrom by a headed screw 35 which likewise holds the two clutch sections in engagement. It will be understood that the spindle 13 eX- tends fore and aft of the machine, so that the aXis of the hollow rock shaft 30-33 eX- tends fore and aft of the machine parallel with the axis of the rock shaft 22, and that the finger piece is arranged to receive a movement from the position shown in Fig.

2 to that indicated in Figj6, and in the general direct-ion of the travel of the carriage. It will also be understood that pressure applied from rightto left on the finger piece 34 is effective to movev the finger piece from the position shown in Fig. 2 to that represented in Fig. 6, to effect a forward line spacing movement of the platen'and also to move the carriage from right to left to begin a newline of writing. Motion of the finger piece from right to left is transmitted .through the hollow` shaft 30-33 and link 27 to the rock shaft 22.

The rear end Iportion of the rock shaft l22 has a hub 36 secured thereto by a pin 37. A crank arm or linger 38 projects from this hub and is received in a cut-outor re cess 39 in the line spacingpawl so that- ,said crank arm isadapted to engage the arms 40 and 41 of the line spacing pawl. A coiled spring'42 surrounds the rock shaft -22 near the rear end thereof and' is secured at one end to the left-hand end platel of the carriage, Whereas the opposite end of this spring is secured at 43 to the hub 36. This spring is tensioned so as to restore the rock shaft 22 andthe parts connected therewith to normal position. The hub 36 is re- 'cessed at 44 to receive a coiled spring 45 one end of which is secured to the huba and the other end of which is received in an opening 46 (see Fig. 5) in the carrier or arm 18. The purpose of this spring is to normally maintain the carrier 18 in elevated or normal position with .the stop 17 against one of the stops fo-rmed by the vcut-out 16 in the sleeve 10. The normal position of the carrier determines the extent of movement that may be transmitted to the line spacing-pawl; which in the present instance is invariable and corresponds to the two teeth 8 of the line spacing wheel. It should be understood that a swinging movement of the finger piece 34 from right to left causes a rotative movement of the hollow rock shaft 33-30 in the corresponding direction,

as indicated b y the lmvermost arrow in Fig. 2. The intermediate connections between this hollow roclr shaft and the shaft 22, however, cause the latter shaft to he turned in an opposite direction, so that the crank arm or finger 38 will effect an actuation of the pawll2l. When pressure is first applied to the finger piece 34, this pressure will be.

'transmitted through the intermediate connections to the crank armor finger 38, which is effective first t-o turn the line spacing pawl 21 on its pivot- 20 to kbring the engaging nose of the pawl into engagement with the line spacing wheel as indicated in dotted lines in F ig. 6. During this initial movement of the finger piece the carrier ld will remain at rest by reason of the surplus pressure of the spring 45 exerted thereon. Vhen, however, the line spacing pawl is brought intro engagement with a tooth of the ratchet wheel, a continued pressure exerted upon the finger piece 34 will cause the line 'spacing pawl, ratchet wheel and the carrier 18 to move together, to effect a-forward line spacing movement of the platen. This simultaneous-movement of the partswill be continued until a shoulder 47 on the pawl has been brought into engagement with and arrested by a stop pin 48. As soon as pressure is released upon t-he finger piece the spring 42 restores the finger piece to its initial position, and at the first portion of this return movement the crank arm ,or finger 1 38 will be brought into contact with the arm 4l on the pawl, thus throwing the paivl olt of engagement with the teeth on the ratchet wheel. A continuation of the return movement ofthe shaft 22 causes the carrier 1S to be turned back to the initial position. It will be observed thatthe motion which is communicated to the carrier 18 is exerted through the crank arm or finger 38 by the direct action thereon Aupon the line spacing pawl; and that the carrier is carried along with the pawl.

The present invention is in the nature of an improvement on the form of line spacing mechanism ordinarily employed in the Monarch machine and by the present construction the same general character of line spacing mechanism may be employedin a machine in which the carriage receives its step-by-step or letter-feed movement from left to right instead of from right to left as is ordinarily the case.

movement of the finger piece 34 in line`spacing movement is changed, by the intermediate connections between said finger piece and The direction ofl the advantages which are obtained from the construction in general use in the Monarch machine.

Various changes may be made without departing from the spirit and sco-pe of my invention.
