o A RRIAGE-CONTROLLING MEANS.

Specification of Letters iatent.

Patented Sept. 3, 1918.

Application'filed October 2 7, 19?.7. Serial No. 198,773.

' ticularly reference to carriage controlling anism and the tabular stop block.

preferred embodiment of the invention here shown, the carriage release mechanism 111- means such as are utilized in connection with labulator stop mechanisms.

The mam ob ect of this invention is to re-arrange the elements associated w1th the transversely movable carriage in such a manner that a lighter and more compact struclBlIl'O. and a better balanclng of the carriage may be obtained.

One feature of the. invention resides in the rearrangement of the partswhereby the tabular stop bar is located in. a plane between the usual carriage release mechanism and tabular stop block together with means for actuating both the carriage release mechcludes 'a pivotally mounted rack releasing lever and the tabular stop block is pivotally Supported on the rear wall of the main frame. in a plane back of the tabular bar' together with means intermediate the rack releasing lever and the tabular stop block which, when actuated by the tabulator key, will tilt the carriage feed rack rearwardly out of engagement with the escapement pinion and will at the same time tilt the tabular stop block forwardly to co-act with the tabular rod.

Another feature of the invention resides in the provision of a brake element mounted independently of the carriage and which moves in the same direction as the tabular stop block to effect braking engagement with the carriage. In the preferred embodiment here shown. the braking element pivotally supported on the stop block and rests with its free end on the escapement frame of the machine, said escapement frame being movable with the earriage for case shifting purposes but not'transversely therewith. hen the tabular block moves forwardly toco-act In the .31 with the stop bar the brake, element, slides over the escapement frame into engagement with a member transversely movable with the carriage.

Other features of construction will appear as the specification proceeds. i In the aceon'ipanying drawings the inven tion is embodied in a concrete and preferred form in 'which Figure 1 is a vertical longitudinal sectional view through the framework of a typewrit-ing machine showing the carriage and its associated elements-but with most of the parts comprising the machine oifnitted.

Fig. 2 is a top plan view of the elementsassociated with the carriage shown in Fig. 1,-

the parts being broken away and in section to more clearly illustrate the device.

Fig. 3 shows a front elevation of the tabular stop block and actuating means therefor together with the brake element carried thereby.

Fig. 4 is a fragmentary view, more or less diagrammatic in character, of the top of the tabular bar showing the eo-action of the stop block with a stop on the bar.

Fig. 5 is a sectional view taken generally on the irregular line 5 5. of Fig. 7 and looking in the direction of the arrows.

Fig. 6 is an enlarged view of the parts shown in. the upper right hand corner of Fig. l with the carriage in its lower case shift position, with. the carriage feed rack out of engagement with the eseapement pi-n ion, with the stop block in engagement with a stop on the tabular bar and with the brake element in engagement with't'he carriage.

Fig. 7 is a view'sin'iilar tov Fig. 6 with the carriage in its upper case shift position and with the parts in normal position.

a rising and falling motion with the case shift mechanism in the usual way but is mounted 111 a well-known manner so as not to partake of the traverse of the'carrlag'e.

.Suitable carriage escapement and release mechanisms are utilized, in the present in stance taking the following form 7 is an escapement pinion mounted in the escapement-frame 6 with-which engages a carriage feed rack 8 suitably supported on a transverse bar or rail 9 provided with rearward extensionslO pivotally mounted at 11 in thecarria'ge frame 3, thecarriage feed rack being normally held in engagement with the escapement pinion by means of .zSPPiHgs 12. 60 indicates an eccentrically a djustable stop, carried by the carriage frame 3, which projects over one of the extensions 10' to .limit the upward movement of the member 9. 13 is a rack releasing lever pivaotally supported at 14 on the escapement frame and having a forwardly projecting member 15 that engages-- underneath the transverse extending member 9 to lift the carriage-feed rack upwardly out of engage Lment with the escapement pinion. when said rack releasing lever 13 is tilted rearwardly on its pivot 14. v16 is a pad carried by the rack releasing lever at the point where it engages with the transverse member 9 and may tact :as a braking element, sufficient pressure being obtained by the abutment stop 60 on the extension 10. 17 is a downwardly projecting extension from the rack releasing lever! '18 is a'tabular bar of any suitable .r 'constru'ction adapted to receive in any letter space position a tabular stop such as 19.

The tabular stop block 20 is here shown in the'forin of a lcver pivoted on the framework at 21 and having a downwardly progjecting extension 22. Normally, a spring 23' urges the tabular stop block into the position shown in Figs. 1 and 7, that is, out of engagement with the stops carried on the tabular-bar. It will be noted that the tabular bar (is in a planebet-ween the carriage escapement and the tabular stop block, 24- is a brakingelement, here taking the form of a lever loosely pivoted on stop block free end 25 resting loosely on theescapement frame 6 and provided with a pad or braking surface 26 adjacent to a carriage connecting rod 27. In order to adjust the .braking element 24 so as to position it properly with respect to connecting r od 27, apivot 28 on which said braking element 24 is mounted has an eccentric portion 29 that extends into the tabular stop block 20, the parts being normally clamped in theposition to which they maybe adjusted by means of a binding s crew' 30, It will be lobsening said screw-30,

the membe. 24 may be adjusted so that it will assume a proper position with relation to the carriage rod 27 Suitableactuating means .for the darriage ;;eleasc jihechanism, the tabular stop block and the braking element carried thereby are provided which in the following, form :v 31

pivotall'y "supportedin the frame work at pinion 7 by 20, having its understood that by the present instance take is a \tabulator, key

32 in any suitable manner and normally' a spring a0; This tabulator key has a vertical arm 33 from which extends a link 34 that connects with the underside of arm 35 mounted on the rock shaft 36 suitably supported in the frame by means of cars 37. At the other end of this rock shaft 36 there is a lever 38 which is in a plane between the downwardly projecting extension 17 of the-rack releasing lever and the downwardly projecting extension 22 of the tabular stop block. It will be understood that when the tabulator key 31 is depressed, the vertical arm 33 is .moved forwardly pulling the link 34 with it and imparting a clockwise turning movementto the rock shaft 36, thereby causing the lower end of the lever 38 to engage with the extension 17 and the upper end of 38 to engage withthe extension 22. This action causes the rack releasing lever 13 to be tilted rearwardly on its pivot 14 thereby lifting the carriage feed rack 8 out of engagement with escapement the engagement of pad 16 with the underside of the transverse member 9, causing the rearwardly extending projections 10 to swing around their pivots 11 against the action of spring 12. At the same time the lower extension 22of stop block 20 is moved rearwardly thereby tilting the stop block itself forward into the plane of stop 19 carried on tabular bar 18, so as toarrest the carriage afterit has moved transversely a predetermined distance. The forward tilting of the stop block 20 causes the braking member 24 to turn on its pivot 28, thereby sliding its free end 25 on the escapement frame 6 and thus movinginto engagement with the carriage rod 27 so that when the carriage release mechanism is actuated brake menber 24 immediately applies the brake surface 26 to rod 27 to retard the transverse movement of the carriage so that stop block 20 will not strike with undue force against the tabular stop. It will be further understood that it is immaterial whether or not the carriageis in its upper case shift position since the escapcment frame 6 moves vertically with the carriage and thereby lifts the braking element 24 with it so that the brake will be applied regardless of wliether or not the carriage occupies the lower case position shown in Fig. 6 or the upper case position shown in Fig. 7.
