TYPE-WRITING MACHINE.

Application filed Karen 9, 1909. Serial No; 482,221.

existing machines, for enablingany one of a plurality of sets of column stops to be brought into use. These stops are referably formed upon the. under edges of t in plate-like carriers which are adapted to engage the col-- umn-sto rack, and are placed at ditferent points aong said under edges, so that certain stops are out of line with others, and

fall into twoor more rows. The key-operated denomination stops upon the machine framework are provided with a guide plate, which may be adjusted backwardly and forwardly,-to bring the denomination stops into line with any selected row of column-stopsfthus adapting the machine for different classes of t-abulating work.

- In the accompanying drawings, 1: is a part sectional-side elevation of an Underwood typewriting machine, embodying the present improvements; the. denomination stops shown adjusted to their forward positions, to cooperate with-the forward row of column stops. Fig. 2' is a perspective rear view of the column-stop adjustingplate and its appurtenances. Figs. 3, 4 and 5 show column-stops in different positions upon the carrier plates, so as 'to fall intothe three rows, seen at Fig.1. Fig. 6 shows a carrier provided with a plurality of columnstops.

Upon a carriage 1. is secured a rack' 2,

along which are placed carriers 3, each having prongs 4, 5, to engage the teeth' on the upper and lower sides of the rack. These carriers are in the form of thin forked plates, to fit betweenthe rack teeth, and may be adjusted to any points along the rack; any suitable locking bar 6 being provided upon the carriage to engage shoulders 7 on the carriers, to retain them upon the bar 2.

Certain of the carriers are provided with forward column-stops 8, certain others with:

column-stops 9 in rear of those at 8, and still others with cohunn-stops 10in rear of those igure 1 different r p I v at 9. It will be seen atFig. 1 thatflthe stops 8 form one row and the stops 9 Specification of Letters Patent. Patented June 14, 19100 another, and the stops '10 a'third, said rows being in the same horizontal tier or plane, and all beneath the rack 2. It, will also he understood that certain of the carriers may 'be provided with a plurality of stops, as seen at Fig. 6. Denomination stops 11 are pro-' vided upon the tops of upstanding rods 12',

the latter pivoted or loosely connected at their lowerends at 13 to the rear ends of levers 14. Iulcrumed at 15 bearing keys 16 at the front of the machine. These column stops project up through a horizontal plate 17', which is slidable rearwardly and forwardly, said plate retained upon a suitable bed 18 by means of keepers or guides 19 engaging the edges of the plate. The latter is provided with a fingcr-pieceQO, whereby it may be drawn rearwardly together with the column stops, the latter vibratingi'reely about the pivots 13 either to the extreme rear dotted line position 12* at Fig. 1, to cooperate withthe row 10 of column stops, or to an intermediate position, to cooperate with the second row 9 of column stops. 1 A spring detent 21 is provided to engage three notches in the plate 17, to retain the same, together with the denon'iination stops, in either of the described set positions. The denomination stops are provided, as usual, with returning springs 23. i

If the operator desires to use the ion ward row 8 of column stops, he simply dopresses-the keys 16 in the ordinary manner. But, 'WllGIli he desires to use tlie middle or rear row of column stops, he grasps the handle 20,'aud pulls the plate 17 and the dcnomination steps back, as far as required,

position the plate. Thus three different classes of tabulating work may be don'e.

without rearranging the column stops along the column stop rack 2; and It will be observed that the device may be" applied to .Underwood and other. machines, with but little trouble and expense.

Having thus described my invention, I claim:

1. In atypmvriting andtabulating mechanism, the uombination with a carriage having a rack, of a series of" carriers alongthe rack, said carriers having column stops at oints' along their under: edges, so that certain stops are out of line with others,

the stops forming a plurality of rows, a series of upstanding denomination-sto rods b'eneath said column stops, a guidep ate up through which the denomination-stop rods project, means to guide said guide-plate in a forward and backward movement to bring the denomination-stops into line with any selected row of column stops, a finger-piece connected to said guide plate, and a detent to hold said guide-plate whereadjusted.

2. In a typewriting and tabulating mechanism, the combination with a carriage having a rack, ofa series of carriers along the rack, said carriers having column stops at different points along their under edges, so

that certain stops are out of line with others,

p the stops forming a plurality of rows, a

series of upstanding denomination-stop rods beneath said column stops, a guide-plate up through which the denomination-stop rods 20 piece connected to said guide plate, a detent 25 to hold said guide-plate where adjusted, and key-operated levers to which said denomination-stop rods are loosely connected at their lower ends.
