SPECIFICATION forming part of Letters Patent No. 546,292, dated September 17, 1895.

Application filed April 2, 1894. s i l No. 506,129- (No model.)

To aZZ whom it may concern.-

Be it known that I, EDW'IN E. BARNEY, of Groton, in the county of Tompkins, in the State of New York, have invented new and useful Improvements in Type-Writers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to type-writing machines, and particularly to the several mechrgnijsms therein which are hereinafter speci- My object is to produce an improved typewritingmachine in which are provided an adjustable carriage-stop, bell-ringer, and paperband, all combined in one; also, a release to permit the carriage to be shifted or to be taken ofi; also, an improved ribbon-vibrator in which the spring of the ribbonguiding arms throws back both the guide and the spindle; also, an improved ribbon take -up or tightener; also, an improved type-bar-lever mounting; also, an improved straight bail easing the operation of the key-levers on the ends of the keyboard, with which bail the keylevers engage; also, an improved line-spacing and platen-rotating ratchet mechanism, and which is also provided with the other novel features hereinafter described.

My invention consists in the several novel features of construction and operation hereinafter described, and which are specifically set forth in the claims hereunto annexed.

It is constructed as follows, reference being had to the accompanying drawings, in which- Figure l is a top plan of the machine, omitting the keyboard. Fig. 2 is a front elevation of the front of part of the carriage and top plate, showingthe stop and bell-ringing mechanism. Fig. 3 is a sectional side elevation of the combined and adjustable paper-band, bell-ringing trip, and stop-button. Fig. 4 is a front elevation of the same, showing the button tilted to pass the stop for margin-printing and also to permit the removal of the carriage. Fig. 5 is a side elevation of the platen-rotatin g ratchet-lever mechanism in its normal position. Fig. 6 is a like View of the same, exceptingthat the ratchet and stoppawl are dotted in, in order to expose the slotway, and showing the mechanism in the position of rotating the platen. Fig. 7 is a top plan of part of the keyboard-levers and their mounting and the bail for easing the opera tion of the key-levers on the ends of the keyboard. Fig. 8 is a sectional elevation of part of a key-lever and its auxiliary and their mounting. Fig. 9 is a vertical sectional elevation, partly broken away, of the top plate, the impression-platen, the carriage, paper- 6:. guide, type-sleeve and its mounting, one of the ribbon-spools, and the ribbon-guide. Fig. 10 is a detail in elevation of the sleeve-lifting cam, actuated by the lifting of the bail by the operation of the lifter key-levers.

Ais the top plate, upon which the front track 2 and the rear track 3 are erectedA being the roller or rollers in the front of the carriage-frame. This frame comprises the ends 5 6 and the longitudinal rail 7, having lugs 7', concaved to fit onto and partly in close the rear track.

B is the platen, mounted upon the shaft 9 and adapted to be rotated by the button 10, said shaft being journaled in said ends.

Upon the bar 11, secured in the ends of the carriage above the rear bearings upon the rear track, a block 12 is mounted, and upon it is secured the paper-band 13, extending through, under, and curving upward partly around the platen and provided with a setscrew 14, by which it is adjusted and secured in any position desired. Near the other end of the bar 11 another paper-band 15 is mounted adjustably by means of a block 16, and upon the lower end of said block the dog 18 is pivoted, provided with an arm 19 and a shoulder 20, said arm being adapted to engage with said block.

Upon the top platea bevel-faced pawl 21 is pivoted, and 22 is the hammer-rod secured thereto and carrying the hammer 23, which is adapted to strike the bell2 t through the opening 25 in the top plate whenever by the traverse of the carriage, while printing,'the dog 18 engages with, rocks, and passes over the pawl 21, and 26 is a post erected upon the top plate, with which the dog engages to stop Y rod upon which thesejlevers are journa led 1 IO 7 toengage with the straight bail 3l, the arms 32 straight and not curved; This bail is; made straight in order .toshorten the arm 34 to brin g v the bail closer-to the cam to re uce the lever-m machine to operate easier in proportion to suchreductionof such leverage. :Agnotherf Y Y 1 1 p wh he p imary am s s si en e i i I 37, and 42 is a spring-bar having one end in Y Y frame and thenceertending upwardandpro? the clog canbetilted, so as: to pass over stop-post for finishing a word at the end By pressure upon the arm-19 the of a line and also for the removal of the carriage, which,thus:reieased, readily slides off from the rear trackway.

This bailis provided with a arearward arm 34, carrying a roller 35, Fig. 10, which, whenever the bail is lifted, is adapted vto engage with the cam 36 and raise thesleeve a to be oscillated andstrike against the platen to print, all substantially laps shownin the wellknown Grandall oscillatory and rotary type sleeve: machine, 1 except that said 1 hail" is age upon said arm and bailand cause the bail38, with which theinner ends oft-he auxiliaries engage, is secured to the shaft 35,;

The ribbon 46 is conducted from one of the spools 47 to the other through the slits between the rotating sleeves 48 and the pins 49, I erected upon the flange 50 upon each upright, said sleeves being rotatably mounted upon the uprights 5 1, erected upon the top plate, a and between them passing through the guide. f arms 45, so that when said arms are thrown forward the ribbon is drawn taut between them.

A plate 52 is pivoted at cupon the end 5 of Yated bythe ey-levers, whie lifters inhal ther ra e he o asthissleeve is raised more i ters less used than for the other V occasionally-used ,characters are represented secured to saidthe carriage and provided with a slot 53,,

The lever 54' is secured to said plate, and 55 is aispringj-pawl in engagement with said ratchet, pivoted upon said plate, so that by Y raising saidlever said plate is raised, lifting said pawl and rotating theratchet and platen. g A; stop-pawl e6 ispivotedxupon said plate and providedatits free end with a pin 57, which 1 is ada ted to engage with one of the holes as in said plate, whereby the space between the V lines of print is regulated andfadjustecd, the

In witness whereof I have hereunto set my hand this 21st day of March, 1894.
