cluding two plates 42 and 43, one of which is behind and the other in front'of the rod 35, said plates being fastened tothe uprights 40 byscrews. Two transverse flanges 44 and 45 connecting the uprights 40, he one below and one "above the rear part of the base 1, t6 which the frame is secured by clamping screws 46 threaded through lugs 47 and screwed-up against the bottom edge of the 'back plate 36. Theiflange 44 has a seriesof' 0 en ended slots in its rear edge, as shown in 1g. 3, and the lower ends of the'levers 34 ass through and are adapted to be 'ded 8 said slots. The frame is secured tot e-top p ate by screws 48 and threaded into t e top plate. The upper ends of 1 the uprights, 40 curve toward the front of the machine and have two plates 51 slidably supported in a bar 55 (Figs. -1 and 3.) having inits upper side a longitudinal slot to receive the front plate 50 of the base 1, 'to

which said bar is secured by clamping screws 57. An indicating plate 58, mounted on the bar 35,'has characters thereon to designate the several keys. i

A plate 60 (Fig. 3) is secured to-the :cross piece 44 by screws 61, in front of the back late 36. Hooks 62, bent down from the orward edge of this plate, have connected therewith the forward ends of} contractile returning s rings 63, the rear errds of which are .5 eonnecte with the levei ris 34.,i"- j The mechanism thus far describe d resem- These stops are, of.

e forward ends of. the push rods 3 are bles that of the well known Gorin tabulatoi so closely that its operation will be under stood without further explanation.

The carriage release is operated by a universal bar 65, carried by arms 66, pivoted on shouldered and headed screws 67, threaded into brackets 68 projecting forward from the uprights 40 a little above the base 1. Each of the levers 34 has aforwardly projecting arm 70 having an'up-turned end standing in front of the universal bar 65. The construction is such that when any of the keys 38 is wardthe rear of the mae'hine. One of the. arms 66 is, in effect, an arm of a bell crank lever having a forwardly projecting arm-71 the third order. Said leverv is pivoted, at 76 to a bracket 7 7 depending from the top plate througha suitable openinglin the top plate 3 and is pivoted at its lower end ona shouldered and-headed screw 80, threaded into' horiz'ontal arm that extends beneath the feed rack 1 1. The construction is such that said rack is lifted out of engagementwith the pinion- 12 and the carriage thus released from the escapeinent, whenever one of the keys 38 is operated.

i The column skipping or column selecting mechanism comprises separate key actuated column skipping stops, three such stops 82, 8.3 and 84 (Figs. 4 and 5) being shown in the present instance. tion shown in Figs. 1- to 5, these stops consist of the ends of the three left-hand levers 34, formed as best shown. in Fig. 5. Each of these three levers at 'its upper end is bent horizontally toward the right as shown at 85,

The lengths of the parts 850i the several levers-are such as to bring the three stops 82, 83 and 84 directly one above another, the

A rack lifter 78 has a stem that extends wardthe front of .the. machine, forming a to the free e ad oi' which, at 72,- is pivoted the lower end of a push link 73,,the upper end of which is pivoted at 74 (Fig. 2) to a lever 75 of- In the form of the invenand the stop ends of the levers roject-toright hand or working edge of each ofthe stops being beneath and in the same vertical ecimal-stop. 33*,as shown in Fig. 4. .The upper parts of the threel'evers 34 that carry the stops 82', 83 and 84', are nested,- as shown in Fig. 5. These three stops project through a vertical slot in the guide plate 53, and the left-hand wall of said slot takes the stress of the blow when the carriage is arrested. Each 01 the column stops 2.8-, 29 and 30 hasits rear leg. extended'som'e distance below the stop .projection 32 (Figs. 1 and 4) and these downplane as the righthand or-working face of the stops .2? and-31 do not .vard extensions are of differentlengths.

The concolumn stop is placed on struotion is such that thedecimal stop may he used as the first column selecting stop, and it may be operated for this purpose by that key 38 that is desi nated on thaJindeX plate 58 by a period. in order to prevent confusion, however,.I prefer to connect this stop nith a second key 90, mounted on a push rod 91, at the extreme left of the-system of rods-37 (Figs. 1 and 3). The plate 60 has a1 opening 92 formed therein, and cars 93 are struck up. from the ends of said opening.

A rock-shaft 95is pivoted to said ears on pivot screws 96., and

said shaft has arms 97 and 9S dependin thin the slot, the left-hand of the decimal stop. for this lever is also similarly slotted and pin1103.(Fig. 2). The construction is such thatif the decimal key 38" be operated, the lever 34* will be operated, the pin 102 moving -idly,inthe slot in the link 1015; if the key90 shaft 95 will be rocked, and

In order to hold oneof the push rods 37 and 91 in normal connects with the rightxhand'side of the lever by means of a headed 1. headed pivotposition when theother rodis operated, each of I these rods is provided with alight contractile spring 105, the rear end of WhlCh,iS connected'with a collar 1'06 securedto the rod bya set screw, and the forward end of which is On the index 58, the

secured to the bar 55. l the key 90 is designated by the numeral 1 as the first column selecting key, the numerals 2, 3 and 4 designating respectively the keys connected with the stops 82, 83 and 84. The

key 38* is designated as the decimal key, and

the succeeding keys by characters indicatin the various denominations up to hundreds ct millions. Y

1 When the machine isusedfor work requir ing the selection of columns only, the column stops 27, '28, 29 and 30 are used, and each of them is set at the numeral on the bar 25 corresponding to that onthe carriage seale. at which it is desired to have the carriage arare employed. When the machine is used for writing columns of figures, the column stops are placed at the numerical positions at which it is desired to write the decimal points. :Somerested; and the column selecting keysl, 2, 3, 4; i

times the same piece of work requires both the selection of columns and theselection of -denominational positions within some or all The machine as shown in the drawings, is eqni 'iped for working in five columns; If it is desired to write $200 the fifth column, .the key marked 4 on the index 58, is first operated. This key being Y a stop 30.

I tages of the present invention will be p crceived from the fact that by adding the three stops 82, 83, saw an ordinary denomination tabula tor, p'rhvision is made for writing five columns of afigures and for instantly selecting any one of said columns. tage is the certainty with which the columns are selected, due tothe fact that the'colu'mn ofeach of the selecting stops moves directly into. the path 0f.the contact surface of the. corresponding column stop without crossing the path of the contact surface ofany other column stop; Another advantage is that all. of the column stops may be set on the bar 25 by reference to. the numerals on said bar without experiment or calculation, due to the fact that the column selecting stops all have their contacting surfaces in the same vertical plane and in the same vertical plane as the contact g surface of the decimal stop.

In Figs. 6,'7 and 8 I, have illustrated another form of my invention. In this form of the invention the arrangement and construction of the keysand push rods, the frame work, the levers 34, the carriage release and all other parts below the top plate are or may be identical with those already de scribed, except in one particularthat will be mentioned. In this form of the invention the columhselecting Stops'SZ, 83 and 84 are on the ends of three levers 110., which are pivoted on a rod 111 mounted at its ends on ears projecting toward the rear of the machinefrom the upright frame pieces 40 as shownin Fig. 6. 1n said fignre this red is shown in section and the left-hand frame piece 40'is broken away. The levers 110 extend from the pivot rod 111 upward and toward the front of the machine and they have their upper ends bent toward the right as shown at 112 in Fig. 7, and the s'to s 82 83 and 84 consist of the forwardy and v downwardlyprojecting ends of these horizontal parts 112. U The right hand or contacting faces of these three'stop's stand above and in the same fore and aft vertical plane asthe contacting face of the decimal stop 33 The horizontally bent parts 112 are nested as shown so that one offthe stops comes under'anotherj The decimal stops .p ro'ect through suitable guiding slots in two lates 113 and 114 which are secured to the ront faces of the forwardly rojecting parts of the uprights 40 and whic 1 are curved as shown 6 to conform substantially to Another advanthe curvature of the standards 4. The con tact'surfaces86 87 and 88 of'the second, I

third and fourth columnfstops, consist in this form of the mechanism of lupwardlyex tending segmental extensions of the stop surfaces 32 which areadapted to"c06perate with the denominational stops 33. The stop surface 86 projects high enough to be in.

rested by the, stop. 82 but not high enough to be arrested by the stop 83. The stop surface 87 is adapted to be arrested by said stop and the stop surface 88 is adapted to be arrested by the stop 84*.

in .a lug or projection 115 formed on the upper edge of the guide-plate 114 The three left-hand levers 3 1 are made a little shorter than the remainder of said levers as shown in Fig. 6 and each of them has'a pin 116 projecting therefrom near its upper-end into a The column selecting stops project through a slot formed a slot 117 formedin one-of the levers 1'10.

The, construction is such that said levers are ormally held in their upper retracted posiifions' but I each of them is adapted to be noved down into the path of the corresponding stop surface. 86 87 or 8'8 when this lever 34-has its upper end moved toward the front of the machine by the operation of the corresponding column selecting key. It will be seenthat in this form of the invention the decimal stop- 35 is ada )ted to arrest the first of theIcolumn stops, the stop 82 to arrest the second of said stops and so on but that the stop 84 is operated by the extreme lefthand one of the keys. In this form of the the left is connected with the decimal stop invention, therefore, they fourth key from and is marked 1, the third. key from the.v

left is connected with: the stop 82* and is marked .2 the second key from the left is marked 3 and is connected with the stop ,83 and the left-hand key is marked "4 and In this.

isconnected withv the stop 84*. form of the invention the denominational tabulator is identical in construction with that shown in Figs. 1 to-5. It will be seen that in thisform of the invention the stop surfaces 86, 87 and SS -are setzto move in paths all of which are in the same plane, which plane in this instance is inclined upward and toward the front of the machinea'srepresented by the dotted line a; nrlfrg. (5; and that the column selecting stops-y-n ove.

in paths transversely ofthis planeand arly perpendicular thereto, so that no cenmn stop ever moves across the path of any other contact surface than that withwhich it is designed to cooperate.

In both forms of the invention, the denomination s'to s are dis osed in a series extending paralle to the direction of travel of the carriage, and 'column selecting stops are disposed in a series at right angles thereto.

v The invention is capablev of embodiment in numerous other forms than the two here 130.
