1 -3 KQN W .Qiwr JI mm F 1L5 .I L 8% Wi/n asses 12 numbered from right to left as 26 of a rocking frame, which usually com- .square shaft 28, said ends being rigidly contilted back to the carriage. stop 21 "by the en agem'ent of the frontface of the column stops 19, the latter mounted upon a cylindrical rod 20 and capable of movement into the path of a cooperating stop 21 usually to receive a threaded stem 22 projecting up .29, Fig. 1, provided in the main frame of "to cooperate" with said scale,

Normally all of the column stops 19 are inefi'ective or out of use, as at Fig. 9, that is,

'can be swung by the rockin 42. But upon the depression of any selected remainsstationary. The index 41, however, '60

. column stop; and further depression of the thrust of the rod 16, serves'to swing the .29; thehandle 18 thus serving as a crank ing machine 11, is'a row of column stop keys seen at i Fig. 2, to indicate first, second, third, fourth, fifth and sixth column stops. These keys are mounted upon front ends of levers 13 of the first order fulcrumed upon a transverse horizontal rod 14. livoted at 15 to the rear ends of the levers are upstanding thrust rods 16, having at their upper ends eyes 17 to engage loosely handles 18 provided upon provided upon the carriage. Each link 16 is made extensible, its lower end being tapped from a pivoted piece 23," which is slotted at 24 to receive loosely the rear end of the lever 13; a. nut 25 being'provided to bind the parts together. The connection of the link 16 to column stop rod 20. is mounted in the ends prises an upper rack bar 27 and a bottom nected by both the rack bar and theshaft. .As usual, the frame 1s lunged upon gudgeons .the machine," and the square'shaft 28 carries an arm 30 to engage a lever 31 pivoted at 32 and having a roll 33 to lift a rack bar 34 from a pin on 35, Figs. 1 and 9,'forming part of the carriage escapement mechanism; said rack bar being carried upon arms 36 hinged at 37 to-the ends of the paper carriage 38, upon which the stop 21 is mounted. A spring 39.keeps the rocking frame normally osition at 'Figs. 5 to 9. The'rack27 is usua ly'p'rovided with a scale 40,. and each column stop has an index 41 v as well as a tooth 42 to engage the rack 27.

they are-in such positions that none of them frame 26, 27, 28, far-enough to et into t he'path of thebefbre said frame is arrested rack 27 with theusual leather pad or brakekey 12, "the, associated rod 16 is thrust up and the connected column stop 19 is first tilted forwardly about the rod 20, to the Fig. 7 position, while the frame 26, 27, 28

limits thisindependent movement of the selected key 12, and consequent upward entire .tram'e forwardly about the trunnions whereby to turn said frame. By this move- I ment of the column stop frame, the stop 19 is carried forwardly enough to be encountered by the carriage stop 21; .and'at the same time, as seen at- Fig. 1, the lever '31 is vibrated by the arm30, and the rack 34 is lifted from the cscapement pinion 35 to release the carriage, which, of course, is

arrested by the engagement of 21 with 19.

Upon releasing the key, the parts are returned to normal positions by springs 39, the rack 34 dropping by its own weight, and a spring 43 returning the key lever 13 to normal position.

During the operation just described, the tooth 42 of the stop remains in engagement with the rack 27. The compression spring 44, housed within the stop itself,-pressesa ball 45 into a groove 46 formed longitudinallyin thetop of the column stop rod 20, and tends always to return the column stop to the Fig. 6 position. During the ,move ment of the column stop from the Fig. '6

to the Fig. 7 position, the ball is. forcedpartly out of the groove 46, and there re mains during the movement of the parts to the Fig. 4 position; but upon release of the key, the spring 44 turns the column stop back about the rod 20 to the norma'l Fig. 6 position.

It will be seen at Fig. 1 that the eyes 17 in the thrust rod 16 are of suflicient length to permit free play of the arms 18 therein, due to the rocking of the frame 26, 27, 28. .Each eye is preferably in the form of a key-hole slot, as shown, to enable the thrust rod to be cast off from the arm 18. This may be done ,by pressing forwardly upon the index 41 to swing the rocking the thrust rod 16, so that the arm 18 is carried to the upper part of the key hole slot; whereupon the" thrust rod 16 maybe swung' backwardly about the pivot 15 to release the rod from the column stop. Thereupon, ,the column stop may be'swung down to theFig. 8 position,to bring its tooth 42 out. from the rack-27, so that the column stop is free to be slid alon its supporting rod 20. f It may then. e turned up to bring the'tooth 42 again into en agementwith the rack; and by pressing orwardly upon. the index 41 the parts may be again swung to the Fig. 4 os tion, "and the thrust rod reconnected to t ecolumn stop. Each column stop may be adjusted along the rack through a range of ten or even morenotches without crampling the rod 16 or lever '13; which is foun purpose. The rod 20 is usually provided with a second groove 47, into which the ball may spring when in the Fig.8 position.

When it is desired to use the ordinary tabulator key 48 in place of the keys 12 a handle49, fixed .upon the rod 20,.is swung 130 in practice sufficient for theie-i .thelrocking ame.- I

a From -'the foregoing, it will 'befsleenthatlx up turnithe rod" 2O ,irom the Fig! 6 Position to) the; 7-?
