GARBIAGE STOP MECHANISM FOR TYPE-WRITING MACHINES.

Specificationof Letters Patent.

Patented Dec. 31, 1907.

Original application filed November 12. 1904. Serial N 0. 232. 113. Divided and this application filed May 18. 1905. Serial No. 260.985.

My invention relates to typewriting ma chines and has for. its object to improve the carriage stop mechanism thereof.

' The invention will be fully described hereinafter and the features of novelty pointed out in the appended claims.

filed by me in the United States Patent Office November 12, 1904, Serial No; 232,413.

' Referring now to the accompanying draw in'gs, Figure 1 is a sectional elevation of a machine in which my improvements have been embodied; Fig. 2-is a rear elevation thereof with parts in section; Fig. 3 is a detail sectional elevation of a column stopand Fig. 4 is a detail sectional elevationof a margm stop. v V

In the drawings, -,1- represents the keys which are mounted on levers 2, fulcrumed on the frame of the machine at preferably in such a manner as tobe easily removable. The levers 2 have any suitableconnection with any approved type mechanism (not shown) as-for instance through the medium of an elbow lever iulcrumed at 5. key lever 2 also operates the'escapement mechanism in., any approved -manner "for instance, through the medium of a universal bar 6 engaged by a toe 2 on the key bar. A key lever 7 (Fig. 1) is connected by a link 8, with a rearwardly extending lever 9,-fulcrumed at 10, the rear end of which engages cally movable stepped stop '12 arranged to be projected more or less into thepath of the carriage by suitable mechanism, or an ordinary stop (without steps) may beused when; denominational tabulation is not desired. The stop 12 is adapted for engagement with.

the stop member 13' of a column stop 13 (or severaloi them) mounted on the-rear rod 14 which is on the rear hinged'portion 1 5' of thecarriage. The stop member 13' may be pivoted to the casing13 and held by a spring 1-3 either in the operative lower position shown in Fig. 1, or in an upper position in The present application is a division of one The which it is out of action. The column stop has a handle 16 for adjusting it lengthwise of the rod, and a toe 17 for holding it after adjustment, said toe engaging a rack 18 on the rear portion of the carriage. A spring 19 (Fig. 4) throws a ball 20 toward a top plate 21 having a ledge or rib 21 so that the casing of thecolumn stop is thrown either toward the rack 18 or away from it.

The margin stops 22 may be of. almost the same construction on the column stop, except that the margin stop proper 23'has a limited swinging v movement lengthwise of the rack 18 in the usual'manner. adjustable on the rod 14 (Whether column stops or margin stops) are preferably r0- vided with two pointers 24, 25, adapts to indicate on the scale 26, one of such pointers being in operative osition whether the stop therefrom.

The release of the carriage from the escapement'for tabulating purposes is effected by means of an arm 27 mounted on the fulcrum 10 of the lever 9. and turning with said lever. Thesaid ,arm carriesa roller 28 (preferably on ballbea'rings) adapted to engage a smooth surface 29 v of the escapement rack or feed rack 30 (Figs. land 2). An adjustable stop screw-31, ermits of regulating the normal position or the'roller 28. Thus atthe depression of the tabulating key, the roller '28 will, engage the rack 30 and release the carriagefby swinging itsxentire rear ortion 15 :away from the feed pinion 32 of t e escapebrought into the'path of thestop 12. Furthermore the rack30 willbe brought against a stationary brake strip 33. I ."I't-is to be understoodthat the carriage consists of two portions, the frontrportion 3e 'of'whichcarries the platen'35, and the rear gortion .15 of whichcarries the rack- 30. o'th carriage portions are ivotally suported onthe-rear rodn36 .o the machine ame, on which rod the carriage ,travls transverselyof the machine.

Various modifications may be made without departing from the nature of my invention. 1 I I claim and desire to secure by Letters. Patent:

1. Ina typewriter-or like machine, a carriage having a swinging section, a feed memher and a column stop. carried by said swing The stops I is engaged with ,t e rack 18, or released -ment. 1 Atthe same timethe stop 13'will be ing section and tabulating mechanism comprising a tabulatin stop adapted to co-' operate with said; co umn stop, an arm connected with said tabulating stop and provided with a roller journaled about a substantially vertical axis and ada ted to en gage the feed member to release t e carriage.

, 2. In a typewriter or like machine, a carria e rovided with a rod and a scale paralle t erewith, a sto adjustable lengthwise of said rodand ca a le of a swingin rnove ment thereon, sai stop being rovi ed with two ointers facing toward eac other, either of which is adapted to indicate on said. scale according to theposition of the stop.

3. In a typewriter or like machineya carriage having a swinging section, a column stop carried by said swinging section, a feed member and a brake on the frame of the machine, a second feed member carried by the swinging section of the carriage and adapted to normally engage said first named escapement member, said second'named escapement member being located between the brake and the first named esca ement memher and means for swinging sai carriage section to disengage the escapement members and to swing said second named escapement member against the brake.

riage comprising two sections, each movable relatively to the other, a feed member and a sto located on one of said carriage sections an movable therewith, a second stop on the frame of the machine ada ted. to be moved into 0 erative position an mechanism sep' arate om second named stop yet connected therewith formovin'g the section of the carriage on which the stop is located, thereby movin said stop and releasing the carriage from t e feedjmechanismn 5. In a t ewriter or like machinea carriage provi ed with a rod and a rack parallel 4. In a typewriter or like machine, a car- H with the direction of its motion, and a bar having a rib, and a stop adjustable lengthwise of said rod and arranged to enga c said rack,-said stop having a spring presse member adapted to engage said rib on one side or the other. s

6. In a typewriter or like machine a carriage provided with a rod and a scale parallel therewith, a stop adjustable lengthwise of I said rod, andca able of a swingln movement thereon, said stoplbeing provi ed with two pointers one or t e other of which is ada ted to indicate on said scale according to t eposition of the sto 4 7. In'at riage comprising a swingingrear section, a stop carried ,therebyso as to be movable transversely of-the carriage path, a second stop located on the frame bf the machine so as to be also movable transversely of the carriage path into operative relation with the ,first named stop, and means connected with the secondnamed stop bntseparate therefrom, for moving the carriage section and with .it the first named stop, before the ypewriter or his machine, a car second named stop engages any portion of JOHN Lorna,
