TABULATING ATTACHMENT FOR TYPOGRAPHICAL MACHINES.

Application filed June 1, 1327. Serial No. 195,700.

My invention relates to tabulating attachments for typographical machines and has a particular reference to attachments adapted to provide additional subdivisions in the columns of type.

, In ordinary typographical machines it is possible to set and to cast bars of a certain length corresponding to the width of acolumn. With my attachment, however, it is possible to subdivide a column into several narrow columns of a desired width.

For this purpose I provide special spaces with sliding cages which are assembled together with matrices in proper positions. I also provide means to hold these spaces firmly in their respective positionswhen the mat rices are being tightened by means of ordinarywedge shaped tightening spaces.

My invention is more fully described in the accompanying specification and drawing in which- Fig. 1- is an elevation of my attachment partly. in section, Fig. 2 is an end view of same, Fig. 3 is an end view of my space, Fig. 4 is an elevation of'same, Fig. 5 is a detailed view of a space holding block, Fig. 6 is a top view of a sliding cage, Fig. 7 isan elevation of a modified arrangement, and Fig. 8 isa detail of another modification.

My attachment consists of spacing members orspaces 1 provided with enlarged tapering and sharp pointed ends 2. Sliding cages 3 are mounted on these spaces. These cages are shaped similarly to thematrices 4 and fit on the same supporting rails (not shown). These cages can slide on the spaces 1 with certain friction. In the central portion they are slightly pinched or depressed, as shown in- Fig. 6, after they have been assembled on spaces 1. The depressed portion fits in a longitudinal slot 5 in the space 1 and prevents the cage from sliding oli the space.

The cages 3 have a different finish from the matrices so as to be easily discernible by the operator. They are placed by hand in desired positions according to the gauge spacing on the assembling rails.

These spaces define tabulating positions in each column. A number of ordinary tapering spaces 6 are placed between matrices (only one such space is shown in Fig. 1).

In order to force the wedge shaped space bars 6 between the matrices a raising frame 7 is provided with guiding rods 8 and an operating lever 9 of an ordinary construction (only portions of the members 8 and 9 are shown). v

The frame 7 has a rectangular bar 10 sup.- porting a plurality of blocks 11. These blocks areprovided with slots 12 fitting over the bar 10 on which they can slide ina vertical direction-being supported in the up; per positlon by means of spiral springs 13 fitted in holes 14 and 15.

The top portions of the blocks. 11 are provided with tapering slots 16 adapted to engage the tapering ends'2 of the space bars 1.

These slots are spaced in accordance with the gauge spacing of matrices, so that the bottoms of slots 16 always correspond to any positio'nsof the spacing bars 1.

The number of blocks 11 determines the number of tabulated columns which canbe set in one standard column of type. Four blocks 11 are shown on the drawingv for four subdivisions of one column, although I any number or such blocks can be made within practical limits. y

The operation of my device is as follows. The operator assembles the matrices on the assembler block (not shown) in a regu lar manner, and he also places by hand my space bars at the points where he wishes to have tabulated columns. In addition he also sets with the matrices and between my space bars, a number of standard wedge shaped space bars or spaces.

The completed line is thentransferred to the position in front of thecasting pot (not shown) and placed in a visa. -The frame? is raised and the slots 16 engage the tapered I ends 2 of the space bars 1. When so en ga'ged the space bars are firmly retained in their respective positions and cannot move sideways. With the further movement of the frame 7 the blocks 11 engage with their 2 upper portions the loweriends ofthe wedge shaped space bars '6' andbegin to 'movethem upwards thereby pushing the matrices apart until they become tightly wedged between respective space bars 1. The matrices are expanded or wedged separately in each line between two successive space bars 1.

The individual spreading and tightening for each block of matrices is accomplished by means of separate blocks 11 with springs 13. When one wedge-spare 6 becomes tightly wedged, the corresponding slotted block 11 begins to slide down on the bar 10 against the tension of the spring 13, until all the other wedge-bars 6 become tight. When the frame 7 finally comes to rest, the blocks 11 will be arranged on differentlevels depending on the amount of spreading required for each corresponding block of matrices.

A modified arrangement is shown in Fig. 7. Here the blocks 11 are provided with dovetailed slots 17 into which special adapters 18 are fitted. These adapters are provided with tapering slots 19 for the tapering ends 2 of the spaces 1. With this arrangement it is possible to raise the spaces 1 higher than the ends of the wedge spaces 6, so that the spaces 1 will be engaged sooner.

The cage 3 being rigid, the space bar 1 can slide freely even when the matrices are jammed ti htly with the wedges 6.

The bloc s 11 in Fi s. 7 are shown with tubula-r extensions 20 shdably fitted over cylindrical lu s 21 on the frame 7. Springs 13 are placed inside of the cylinders or tubes 20.

A modified form of an adapter is shown in Fig. 8. Here the adapter 21 has a taperin point and the lower end of the space bar 1 is provided with a tapering slotted portion 22 fitting over the tapering point 23.

Im ortant advantages of my attachment are t at it enables the operator of a typographical machine to set lines with subdivid ed tabulations, for instance, several rows of figures with words or letters may be ar ranged in a tabulated form within a single column. My attachment can be easily adapted to any existing typographical machine and is simple and easy for operation.

Ielaim as my invention:

In a tabulating attachment for linotypes, the combination with a plurality of space bars of means to support said space bars in predetermined positions between matrices when said matrices are set to form one line of print, a plurality of spreading tapering space bars between said matrices and said space bars, and means to tighten said tapering bars individually for each block of inatrices separated by said space bars, said tightening means being also adapted to hold said space bars in relatively fixed positions.

2. In a tabulating attachment for typographical machines, the combination with a pluralit of space bars of cages slidably mounte on said space bars, said cages being of the same outside shape as matrices of said typographical machine and being adapted to be supported together with said matrices on said typographical machine, a plurality of tapering wedge bars adapted to be supported between said matrices, when a plurality of said matrices are set for a line of print, :1 raising frame, a plurality of blocks slidably fitted on said tran'ie, resilient means to support said blocks in their upper positions, said blocks being provided with slots adapted to engage lower ends of said space bars.
