TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Jan. 241, 1911.

VTo all whom 'it may co'ac'em:

Be it known that I, WALTER E. BARNARD, a lcitizen of the United States, residing in Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvementsin Type- Writing Maehines,. of which the following is a specification.

This invention relatestov margin regulat-` ing means for typewriting machines, and morey especially to the margin controlling vdevices on the so-called wide-carriage maehines.

- 'In writing machines of the Underwood type, ityis customary to provide a rack having arms journaled on the gage-supporting rod extending parallel with the rack, the latter also havin an arm for actuating the usual signal .an key-locking mechanisms when the rack is rocked. To rocksaid rack, one of'a pair Ofinargin gages sliding 'on the gage-supporting rod is provided with a f cam riding upon the rack, which cam is pressed down when-engaged by a tappet on' the carriage, to turn with the gage around The margin gages operate -to control the .widths of the right and left-hand margins of the sheet, in a well known manner. The inner arm of the' rack, however, being journaled onthe rod midway of its ends and of the run of the carriage, limits the range of adjustment ofrthe gages lsliding on. .the rod, the left hand gage cooperating with, and being 'adjustableonly between the arms of, the rack, and the right,I hand gage being limited in its adjustment toward the left by its engagement 'with the inner arm of the rack. One reason for usingsuch a short rack is that the rack mustv be level at all times, as sagging or springing would disar-- operator greater control of the widths of' the margins, so that both gages may slid to one extreme or the other of the'run of-the carriage, while preservlng the advanta s of the present construction. To eiiect this end in an eilicient manner, and to provide a device easily applicable to existing machines,

both gages being adjustable between the arms. of the rack from, end to end of therange of movement of the carriage.

In the accompanying drawings, Figure 1 is a perspective view, illustrating my invention applied to an Underwood type of front strike writing machine. Fig. 2 is a cross sectional view, showing'the manner of sustaining lthe gage-supporting rod intermediate its ends, and showing the right hand gage clearing the rack. LFig. 3 is' a detail plan view, showing the right hand gage and carriage stop, and the connection between the stop-controlling lever and the leverfor releasing the letter-spacing rack. Fig. 4 is a plan view, showing the margin gages adjustable to either extreme of movement of the carriage, parts being omitted to better disclose the construction. Fig. 5 is a crosssectional side elevation, showing the lettery spacing rack released through the operation of the stop controlling lever. Fig. 6 is a similar view showing the parts in normal position.

The usual carriage l of said Underwood writing machine runs upon a rail 21 ysuported at its ends in the standard 2 of a rame A. The carriage has a roll 23 to runupon sfaid rail. Upon-she carriage is xedvthe usualtappet 3 to engage a signaloperating and key-locking cam 14 mounted upon a margin 4gage 5 having a handle 5 for convenience in adjusting the margin gage back and forth on a gage-supporting rod 6, to control the point in the letter-spacing travel of -the carriage at which the signal shall be operated and the keys locked,

to terminate the line of writing. The gagesupportingfrod is fixed at its ends in the standards 2 of the frame and lies parallel with the rail 2l.

The function of the tappet 3, as usual, is to press the cam 14 down and thereby rock forwardly the pendent lever 16, said arm having at its lower end a head 16. to engage bell 171. The head also carries a pin 17 to engage a spring actuated arm 18 on a rock shaft 18", which carries a lookin bar 18, normally idle, but swung forward yby 105 a cam 17 on a hammer 17 which rings a'4 the `lever 16 to lock .the keys 18c after the bell 17h has been sounded.

rlhe lever 16 issecured to a bar 8 parallel with and having arms 4 journaled on the gage-supporting rod 6; but instead efemploying the usual short bar with an inner arm journaled midway of the rod and theren by limiting the adjustment 4of the margin gage 5, I extend said bar clear across the machine and journal its arms` onv thel rody near its'opposite ends, preferably beyond the range of movement of the `carriage 1.

The bar 8 and operating lever 16 may bereadily applied to the usual gage-supporting rod commonly employed in machines of the Underwood type', Without alteration of the other parts of the machine. p It will be noticed thatI the bar is angular in cross-secg tion, to add `strength and resist sagging or springing;l such bar reaching across the machine'without intermediate support. When the cam 1li is pressed down by the tappetf 3' rod. It will be noticed that by extendingthe rack bar 8 clear across themachine, the arm 4 thereof, usually journaled on the rod midway of its ends, is set over out of the way, so that the travel' of the gage 5 "is no longer limited thereby, andan ample range of adjustment of the gage yis permitted.

To support the gage-rod 6 without limit'l ing the range vof adjustment ofy the gage,

said rod is rigidly supported about midway of its ends, as by a hanger 9 depending from the cross-bar 10 of the frame 2, and secured at its lower end to the rod. Preferably, the rod is recessed at 11 to form a socket for' the lower end of the hanger, which may be fastened to the gage-supporting rod by a pin 9a. The sleeve 12 of the gage, sliding on the rod, is sl-itted, as at 13, to permit the gage to clear the brace or strut 9 when adjusting the gage from end to end of the rod., The rocking of the cam 14 to operate the signaling and key-locking mechanisms also rocks the margin ga e 5' on the gage-supporting rod 6, and t eslit 13 is made ofl suiiicient width to perniit such rocking movement when the hanger 9 isembraced by the gage.

To regulate the Width' of thewlefthand margin of the sheet, the carriage is ,equippedy with a stop 2,5 to engage a shoulder 2li provided upon a margin gage# .19 which is adjustable along the rail 21 to arrestthe ear;

,voi

riage'when returning to begin a new line. The margin gage 19 is supported jointly' upon the rail 21 and the rod. 6 by bearing sleeve 2O and 26,' respectivel and hence the' rocking of the rack has no e ect on the margin gage 19, vbecause of its double support on the stationary rod and rail. The sleeve 201m the rail 21 is slotted, as at 22, to permit the wheel 23 on the carriage to 'run vpast the sleeve, as when shifting-the carriage past the margin gage. The body of said margin' gage is well above the rack 8 soy as not to interfere therewith, and the sleeve 26 on the rod is slitted, as at 27, to permit theI gage 19 to be slid past the brace 9.V Hence there is nothing to obstruct the adjustment of the gage to any `position betweenthe left and right hand portions of the rod 6 and rail 21, the range of adjustment of both gages^being no longer obstructed by the inner arm of the rocking rack. By dropping the 'brace from the cross bar 10 instead of'projeeting itfrom the rail 21, the brace lies out of the plane Y of the4 body portions of the gages, which need onlybe arranged to clear the brace at its point of engagement` with the .red .6. Accordingly the rack 29 usuallyformed'on the front side ofthe rail 21 to be engaged by a dog 28 pivoted at 28a on the gage 19 is extended nearly to the end of the rail 21. as shown. A linger piece 28b onthe dog enables the dog to bereleased from its rack.

To permit the operator to write in the left hand margin, or in a column lying be- '100 hind the right hand margin gage, the carriage stop 25 is usually mounted on a lever 30 pivoted at 31, to the carriage 1 and having a key 32, the depression of which rocks the lever to throw the stop to inoperative position, so that it will clear the shoulder 24 on the return of the carriage to the beginning of ay line.' In'thus' returning the car- .riagepas't the gage, the operator may overrun the point in the margin at which he wished to stop the carriage, especially in machines having .wide carriages,`vvhich re-l quire the 'application lof greater force to i return them than do the usual short carriages. In such event, the carriage cannot be moved in'letter-spacing direction back to such point, (because of the engagement of the usual letter-spacing'rack 33 hinged to the carriage at'34, with the escapement-con trolled wheel 35), except bythe manipulation ofthe rack-releasing lever 36, or by operating the usual space bar, Awhich delays the operator. v

To enable the operator to morel speedily locate the carriage at the desired stoppingy point behind the margin gage, I provide a single switch for effecting the release of the letter-spacing rack 33 simultaneously with the shifting of the stop -25 to inoperative position, thereby permitting the carriage to shlfting lrack-,releasing lever,"so that the latter lever may be operated to releasethe rack from the escapement, against the tension of a returning sprintf 39, Without operating the stopever. Depression of the stopshifting lever, therefore, will' operate the releasing lever 36 controlling the letterspacing rack 33, to release the carriage 1 from the escapement and throw the stop 25 to ineffective position.

It will be understood that the invention i herein disclosed is not restricted to wide o the opposlte en carriage machines. Variations may be resorted to Within the scope of the invention,

and portions of the improvements may be used without others.

Having .thus described .my invention, 'I claim: y

1. In a typewriting machine, the combinal tion with a carriage and a frame, of a agesupporting rod eXtendin across the mac xine, a pair of gages, both slldable on the rod to either extreme of movement of the carriage,

a rocking rack 'ournaled on the rod near ds thereof and outside the range of movement of the carriage, the gages both being adjustable between the en s of the rack, one of the ages having a cam coperating with the rac and engaged by the carriage to rocklthe rack, and 'a signal mechanism operated by the rocking of the rack.

2. In a typewriting machine, the combination with a frame, a carriage thereon and a diate yits ends; the gages being slitted to pass by the support in their adjustment to oppoj' site sides of the machine.
