TABULATING MECHANISM FOR TYPE-WRITING MACHINES SPECIFICATION forming part of Letters Patent No. 752,540, dated February 16, 1904.

Application filed May 26, 1902. Serial No. 109,013. (No model.)

T at whom it may concern:

Be it known that I, CHARLES N. FAY, a citizen of the United States, and a resident of Chi- .cago, county of Cook, and State of Illinois,

have invented certain new and useful Improvements in Tabulating Mechanism for Type- Writing Machines, of which the following is declared to be a full, clear, and exact description.

The invention relatesto .tabulating mechanism for type-writing machines, by which various items may be accurately and quickly positioned upon the paper Without resorting to the machine-scale and without repeated operations of the space-bar, and it seeks to provide a simple and effective construction of few parts.

With this object in view the invention consists in the combinations and arrangement of devices and in the features of construction set forth in the followingdescription, illustrated in the accompanying drawings, and particularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of the type-writer top plate, paper-carriage supported thereby, and the improved tabulating mechanism. Fig. 2 is a detail end elevation of the carriage-release used in connection with the tabulating device. Fig. 3 is a detail section upon line 3 3 of Fig. 1. Fig. 4 is a detail section on line 4 4 of Fig. 1. Fig. 5 is a detail section on line 5 5 of Fig. 1. Fig. 6 is a detail section of the carriage-rack on line 6 6 of Fig. 1.

, he tabulating mechanism is shown applied to that sort of type-writing machine in which the carriage is rigidly held against lateral shift; but it will be understood that the improvement may be readily adapted for use in connection with type-writers having shifting carriages for printing upper-case letters and to other types.

In the drawings many of the well-known parts of the type-writer are omitted.

The top plate 10 of the machine carries the longitudinal front and back guide-rails 11 and 12. The carriage comprises front and

rear rails

13 and 14, connected by the end. bars 15 and 16 and mounted to slide within the guiderails 11 and 12. The carriage is propelled in the usual manner by a drive-strap 17, engaging a hook 18, fixed to the rear carriage-rail 14. To effect the step-by-step feed escapement, dogs 19 and 20 of any suitable construction are mounted upon the dog-rocker 21 and arranged to engage the rearwardly-pro jecting teeth upon the horizontal carriagerack 22. The latter is connected by short bolts 23 (see Fig. 6) to the pivot-pieces 24, rising from the rear carriage-rail 14, so that the rack may be swung out of engagement with the escapement-dogs and permit a free run of the carriage.

The cylindrical paper-platen 25 is carried upon a shaft 26, which is journaled at either end within the end bars 27 and 28 of the platenframe. The end bars are connected by the front and rear

longitudinal rods

29 and 30, and are-provided at each end with pivot-pieces 31 and 32, which are pivoted within the

uprights

33 and 34, rising from the end bars 15 and 16 of the carriage.

The parts thus far described are common and well known, form no part of the present invention, and any suitable form or arrangement thereof may be employed.

The carriage scale-bar 35 and cooperating printing-point indicator 36 are located at the front of top plate 10, and one of these parts is connected to shift with the carriage, while the other is mounted upon the machine-frame. In the present instance the scale-bar 35 is carried between

uprights

37 and 38, fixed to the front carriage-rail 13. The bar is oylindrical in section and provided with a flattened upper face upon which the letter-space scale is marked. The printing-point indicator 36 is preferably pivoted, as shown, (see Fig. 3,) between ears 39, formed upon a bracket 40, which is fixed to the front guide-rail 11. The inner end of the indicator is provided with an upwardlyprojecting wedge-shaped piece 41, which cooperates with the scale to indicate the precise position of the carriage, and the outer end of the indicator has a forwardly-projecting tailpiece 42, by which the indicator may be tilted for the purpose hereinafter described. In the present invention the carriage scale-bar 35 also serves as a colurnn-stop bar, upon which are mounted a series of column-stops or riders 43. These stops are preferably adjustable in position, and for this purpose the bar 35 is provided upon its front and rear side with a series of grooves or notches 44 at letter-space distances and corresponding to the scale marked upon the bar. The bifurcated column-stops 43 are readily inserted from above within the seats or notches 44 to define various columnar points along the line of print in keeping with the desired arrangement upon the paper. By thus utilizing the letter-space scale-bar as a support for the column-stops the use of a separate piece therefor is thereby avoided, and, moreover, the column-stops are located at the front of the machine and may be conveniently and readily adjusted to desired position.

The column-stops 43 are provided with forward ly-projecting working portions 45, which stand normally above and out of line with the upwardly-projecting piece 41 upon the printing-point indicator 36. Means are, however, provided for effecting the engagement of the part 41 with the Working portion 45 of the stops to arrest the free run of the carriage at the various columnar positions. For this purpose the scale-bar 35 is preferably shiftably mounted and preferably provided with pivotsections 46 at each end, engaging the

uprights

37 and 38, so that the bar may be rotated about a longitudinal axis to bring the working portions 45 of the stops in line with the piece 41, as indicated on dotted lines in Fig. 3, in order to arrest the free run of the carriage by the engagement of the stops therewith. The piece 41 upon the printing-point indicator thus serves as a stop-dog and avoids the use of a separate piece for this purpose.

To release the carriage for its free run and to shiftcolumn-stop bar 35, arod 77 is transversely arranged at the right-hand end of the carriage above the end bar 16 and rests at either end upon the front and

rear carriagerails

13 and 14. The rod 47 is longitudinally shiftable and is limited in such shift by the downwardly-projecting stop-pins 48 and 49 thereon, which engage, respectively, with the edges of the front and rear carriage-

rails

13 and 14. Rod 47 is spring-held in its forward position with the stop-pin 48 against the car riage-rail 13 by a coiled spring 50, which extends between

pins

51 and 52, fixed, respectively, to the rod and to the carriage end bar 16. The rear end of the bar engages the lower end of adownwardly-projecting pin or rock-arm 53, fixed to the end of the pivoted carriage-rack 22. A short rock-arm 54, fixed to the end of the column-stop bar 35 outside of the upright 38, extends downwardly, and its lower rounded end engages a slot formed in the rod 47 An operating-key 55 for actuating the re lease and for shifting the column-stop bar 35 is preferably mounted at the forward righthand end of the carriage and for this purpose is provided with a laterally-extending portion 56, which is journalcd in the bracket 38 in front of and parallel to the right-hand end of the stop-bar 35. The actuating-key projects forwardly and is provided at its front end with a convenient laterally-extending fingerpiece 57. To the end of the portion 56 of the shift-key 55 and outside of the end of the upright or bracket 38 is fixed a downwardly-extending rock-arm 58, which is provided with a rounded end or head engaging a slot in the forward end of the rod 46. By depressing the shift-key the actuating-rod 46 is moved rearwardly against the tension of the spring 50. The carriage-rack 22 is tilted and disengaged from the escapemcnt-dog 19 through the medium of the pin 53 to release the carriage for a free run. At the same time the stop-bar 35 is rocked upon its longitudinal axis through the medium of the rod 54 to bring the working portions 45 of the columnstops 43 in line with the stop-dog 41. The carriage is then free to be propelled by the drive-strap 17 toward the left until one of the column-stops engages the stop-dog 41. This movement, however, is completely under the control of the operator, since the shift-key actuated by him is connected to the carriage, and any sudden shock or jar upon the parts incident to the contact of the column-stops with the stop-dog is readily avoided. Moreover, the position of the shift-key at the right-hand end of the carriage is convenient for the operator and may be readily actuated with the right hand. As soon as the shift-key 55 is released the actuated rod 46 is retracted by spring 50. The column-stop bar 35 rocks in the opposite direction for moving the working portions 45 of the column-stops out of line with the stop-dog-41, and carriage-rack 22 is returned to normal position into engagement with the escapement-dog 19. The parts are so arranged that when the carriage-rack reengagcs the stop-dog 19 the carriage is spaced ahead through a portion of the tooth in order to bring the particular column-stop which has been engaged by the stop-dog directly opposite the latter. The entry of items may then be effected by the manipulation of the usual type-keys of the machine.

The bar 35 also serves as a convenient support for the right and left hand margin-stops 59 and 60. These stops (see Figs. 4 and preferably encircle the bar, as shown, and are provided with forwardly-projecting portions 61, which are arranged in position to engage the sides of the printing-point indicator 36 at the end of the travel of the carriage in either direction. The margin-stops are adjustable along the bar, and a catch 62, pivoted to its upper end, is arranged to engage the notches 44 upon the rear face of the bar 35 to securely hold the stops in adjusted position. Forwardly-projecting spring-held linger-pieces 63, connected to or formed in piece with the latches 62, afford convenient means for releasing and adjusting the margin-stops.

The margin-stops 59 and 60 are preferably held against rotation by the rotatable columnstop bar 35, and for this purpose the lower faces of the margin-stops are flattened and rest uponthe front carriage-rail 13, while an ofiset or shoulder 64: engages the inner edge of the rail. By this means the margin-stops are readily fixed in position and are not disturbed by the shift of the tabulating columnstop bar. By depressing the tailpiece 42 of the printing-point indicator 36 the latter may be lifted above the right-hand margin-stop 59 in order that a few additional characters may be written in the margin, if desired.

By thus providing the usual letter-space scale-bar of the type-Writer with a series of adjustable stops and by connecting it to shift with the usual carriage-release bar the invention provides a simple and convenient tabulating mechanism without the use of additional parts.

It is obvious that numerous changes could be made in the details of construction without departure from the essentials of the invention. For example, the shift-key could be arrangedto shift the stop-dog in line with the column-stops instead of shifting the columnstop bar. Other changes could be readily made by the skilled mechanic.
