PATENT WILLIAM R. FOX, OF GRAND RAPIDS, MICHIGAN.
TABULATOR FOR TYPE-WRITERS.
Specification of Letters Patent.
Patented M'arcli 17, 1908.
Application filed May 6, 1904. Serial No. 206,684.
To all whom it may concern:
Be it known that i, XVILLIAM R. F ox, a citizen of the United States, residing at the city of Grand Rapids, county of Kent, State of Michigan, have invented certain new and useful Improvements in Tabulators for Type Waiters, of which the following is a specification.
This. invention relates to improvements in typewriters, and particularly to improvements in tabulating devices therefor.
The objects of this invention are: first:
'to provide a simple, efficient, and durable,
tabulating device, which is simple to construct and easy to operate. Second: to provide such a tabulating device which does not interfere with, or make necessary, any material alterations in the typewriting ma chine, the machine being supplied with the tabulator, or the tabulator omitted, without Inarring the appearance of the machine.
Further objects pertaining to structural details will definitely appear from the detailed description to follow.
1 accomplish the objects of my invention by the devices and means described in the following specification, and particularly pointed out and defined in the claims.
A struc ture embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which-- Figure 1 is a side elevation view of a typewriting machine with only such parts present as are necessary to illustrate my improved tabulating device, portions of the frame being broken away to show details of construction. Fig. 2 is a rear elevation view of the structure appearing in Fig. 1, only such parts being shown as are necessary to illustrate the arrangement and the mode of oper ation of the tabulating device. Fig. 3 is an inverted plan view of a typcwriting machine showing the relation of the parts of my improved tabulator, only portions of the ma chine pertaining to the tabulating structure being illustrated. Fig. 4 is an enlarged detail view of the releasing lever for raising the rack out of engagement with the driving pinion when the tabulating device is operated. Fig. 5 is a detail sectional view taken on line 55 of Fig. 4. Fig. 6 is an enlarged detail sectional view of one of the release bar keys of the tabulator, and the front of the ma chine, showing the arrangement of the spacer bar and its stop in that connection, the same being taken on a line corresponding to line 6-6 of Fig. 7. Fig. '7 is an enlarged detail sectional view on line 7---7 of Fig. 6. Fig. 8 is a detail view of one of the adjustable sto s 12 which co-act with the tabulator stop bar i.
in the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar letters of reference refer to similar parts throughout the several views.
Referring to the drawing, the frame A of the machine is of the usual Fox typewriter construction, and is provided with a top plate A which has the usual carriage ways K and the reciprocating carriage J therein. The carriage is actuated by the spring drum P which is connected thereto by the usual means.
The keys of the typewriter are of the usual form for type bar machines, and are not here illustrated for the reason thatthis tabulating device is independent of the keys and supported below the same.
B is the front bar of the machine arranged in front of key bank, and is here made detachable. \Yhen the tabulator is present, it extends down as at l) and ispcrforated for the passage of the key stems of the tabulator, which are straight horizontal bars underneath thekcy levers. "lhis front bar B of the machine is provided with inwardly projccting fingers Z), suitably covered with felt, or other cushioning material, to serve as a stop for the spacer bar ii. 'lhis spacer bar H is connected to the usual spacer lever ll, supported in the machine as illustrated.
On the under side of the spacer bar H is a bracket 72, which extends downwardly and then laterally underneath the cushioning stop linger b, which limits the motion of the spacer bar in the upward direction so that the movements of bar are so controlled that they will not interfere with the tabulator mechanism beneath.
'lhrough the lower portion of the front cross bar B are perforations for as many key stems as it is desired to have stops in the tabulator, and also aperforation at each side of the machine for the passage of the reciprocating rods I) I). These rods D D are conncctcd to the release mechanism for releasing the carriage to allow it to contact with the tabulator bar, which release mechanism consists of a cross bar 1) across the front of the machine, below and in front of the key bank, which is supported by the reciprocating rods guide I at the rear of the machine.
D D. These rods D D extend rearwardly through the front bar B of the machine, as above stated, and are there connected to arms F at each side of the machine. These arms F are connected to a transverse rock shaft F. A erforated arm F extends forwardly from t 's rock shaft F, through which erforation extends a vertical, or substantia fly vertical, rod This rod f is a loose fit in the perforation'of the arm F.
Sto sf f are located above and below the arm I at such distance as to permit free movement of the arm F for a considerable distance, without actuating the rod Supported on the rear portion of the frame of the machine is a lever L to which the rod f connects, and this lever is arranged beneath the rack bar M so that, when the rock shaft F is actuated by the movement of the arms F to the rear to thelimit of their movement,-the arm F will'strike the lower stop f, pulling down the end of the lever Land raising the rack bar, thereby releasing the same. The upper surface of this lever is slightly curved so as not to engage the teeth of the rack bar, but to permit the same to pass readily over it.
The arm F of the' rock shaft F is drawn normally to the front by a coiled spring a.
It will be observed that when the bar D is pushed in to the'limit of its movement, its 'eflect will be to release the carriage and allow it to move under the action of its driving pring towards and against the stop bar of the tabulator. This bar D is not in any way connected to the keys of the tabulator.
Supported on the bars D of the machine and free to reciprocate thereon, is acrossbar E, to each side of which are secured forwardly extending rods E. These rods E connect to arms G of a rock shaft G which is supported transversely in the rear portion of themachine.
An arm G is secured to this rock shaft G about midway of the width of the machine, towhich arm the tabulator bar I is pivoted, extending backwardly through a suitable The upper end of this bar is provided with graduated notches about one-eighth of an inch dee and about one-eighth of an inch apart, or the distance of one of the letter spaces of the typewriter, whatever that may be, the succeeding notches being at a regular variation of helght.
Underneath the machine is a transverse bar B secured by brackets or arms B B to the front bar B of the machine, the bar B being parallel therewith. Through these bars extend the key stems C of the tabulator. Coiled springs c actingagainst the collars c, serve to return these keys normally to the front of the machine, so that they may be actuated by pressing the key buttons C. The key buttons C reject through apertures in the release bar Collars c are secured by ssaoas on ushing any particular key in, the bar E wil be pushed forward a distance corresponding to the length of the key stem, when t e-key is pressed close up against the front bar B. As the key buttons 6 are of less diameter than the apertures in the bar D they extend completely through the bar D, when it is pushed back, the thumb or finger of the operator, whichever may be used, will actuate the bar D so that, as the tabulator key completes its stroke, the carriage will be released to carry it towards the left, where it will be stopped by the tabulator stop in the rear.
Stops n are provided on the stop supporting bar N at the rear of the carriage so that the machine can be set or adjusted to tabulate at any fixed point desired on the page, and, by providing a series of these stops n, different sets of tabulations can be accom-, plished on the machine.
As the tabulator key stems C are of diflerent lengths, when they are pushed in, it will be noted that the bar E will be pushed different distances corresponding to the length of the key stems, and the tabulator stop bar I will be raised a corresponding amount, so that each of the keys controls the stop bar,
and raises it a distance proportionate to the length of the keystem, securing a corresponding point for beginning a number, thereby making the device eflective for any tabulating that may be desired where figures of difierent denominations are to be correctly printed in columns. The stop at the left sets the tabulator for units, the next stop to the right thereof setting the same for tens, and the next stop for hundreds, etc.
I have shown my improved tabulator in the form preferred by me, and I believe the connections to be arranged in the most compact and satisfactory manner. I am aware, however, that the structure can be greatly modified in its details of construction without departing from my invention, and I desire to claim the same specifically as well as broadly. r
Having thus described my invention what I claiin'as new and desire to secure byLetters Patent is 1. in a tabulator for typewriters, the combination with the es ca ement mechanism of the typewriter of suita ile adjustable stops at the rear of the carriage; a vertically mov able tabulator bar with graduated notches at its upper end for-engaging the stops of the said carriage;' a rock shaft in the lower rear part. of the machine with an arm connected to said tabulator bar; a transverse actuating bar suitably supported underneath the type series of horizontal tabulator keys C of graduated lengths supported in suitable transverse guide bars towards the front of the ma- ,chine, with individual springs for throwing each of the same normally forward, arranged to act upon the transverse actuating bar whereby the keys will actuate the tabulator bar and elevate the same to bring the graduated notches corresponding to each of said keys into operative position; a release lever L arranged under the rack bar and adapted to act upon the same, the said lever being curved to permit the rack bar of the ma chine to pass freely over it; a rock shaft in the lower part of the machine with a. perfora ted, substantially horizontal arm; a connecting rodffrom the said lever L to the said rock shaft arm, extending through a. perforation therein and provided with stops arranged to permit the free movement. of the an arms on the said connecting rod] to cause the actuation of the lever toward the end of the stroke of the arm; a transverse release bar D below and in front of the type key bank of the machine, perforated for the free passage of the horizontal tabulator key stems C; connecting rods from each end of the release barD with downwardly depending arms on the said rock shaft of the release mechanism, all co-acting substantially as described and for the purpose specified.
