Specification of Reissued Letters Patent. Reissued D131, 11, 1913.

Original No. 960,854, dated June '7; 1910, Serial No. 324,451. Application for reissue filed June 1, 1912;

Serial No. 701,055.

To all whom it may concern Be it known that I, GEORGE W. DUDLEY, citizen of the United States, residing at Staunton, Virginia, have invented certain new and useful Improvements in Type- WVriters, of which the following is a specification.

My invention relates to tabulating mechanism for typewriters and one object is to provid series of stops one for each column which co-acting with the tabulating stop will'enable the carriage tobe instantly set at any desired position for printing in the proper position in that column the figure of the desired denomination. I aim also to provide a tabulator in which by moving an index to the proper position on a scale the paper carriage will be brought to position for printing the number accurately according to its denomination".

In carrying out my invention I provide a hand operated device such as lever at or adjacent the key board and by moving this in relation to a suitable scale or dial the paper carriage can be moved to or set in di erent positions according to the marks on the said scale. I have sought also to provide automatically operating means for taking up the shock incident to releasing the carriage to be impelled by its spring freely and then arresting it suddenly said meansbeing thrown into operation automatically when the tabulating is -to be done but being normally inactive as against the force of the carriage spring. V

The invention consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view of a typewriting machine of the Hammond type with parts in section and parts omitted. Fig. 1 is a detail view of the scale and the lever cooperating therewith. Fig. 2 is a rear view of the machine with parts omitted. Fig. 3 is a detail view relating to the cushioning or retarding spring, this being a section along the cushioning spring shaft. Fig. 4: is a side View of the drum of the cushioning spring. Fig. 5 is a plan view of the tabulating stop.

\Vhile I have shown my invention as einbodied in a machine of the Hammond type it will be understood that I do not limit myself in this respect as the invention may be applied to other styles of machines.

In the drawings the paper carriage is shown at l guided as usual upon rollers 2, 8 and under tension of a spring in a barrel or drum 4:, which is connected to the carriage through the rack 5 and a suitable gear.

The escaperhent'of the Hammond machine being well known needs no descrip tion herein. In orderto release the carriage the Hammond machine is. provided with a release bar 6 extending lengthwise beneath the carriage from end to end .thereof. When this release bar or disengaging rod is forced to the rear the disengaging sleeve is operated, a part of which is shown at 7 and this action frees the carriage from its escapement to allow it. to run free to the left under the act-ion of the spring in the barrel 4. By my invention the carriage will be set free as just described and will be arrested at the point desired by the operator for performing the tabulating work. This release bar 6 is substantially the same in function and arrange- I ment as that disclosed in the patent of the United States, granted to James I5. Hammond, September 20, .1883, No. 290319,- and the escapement mechanism controlled by this release bar is the same as that disclosed in said patent.

The stops on the carriage are supported in or fixed to a bar Sfixed to the bar 9 forming a part of the machine. These are set permanently in position at regular distances apart in the present instance or these distances may be irregular. so long as the stops are set apart distances corresponding to the letter spaces.

The 'tabulating stops which are thrown into and out of line with the stops. on the carriage are formed on a segmental 'piece"10 fixed to a rock shaft 11. at the rear of the machine, said rock shaft being journaled in brackets 12 secured to the main frame. This the machine.

sothat its end will force back the disengaging rod 6 and through the well known Hammond disengaging sleeve the carriage will be disconnected from its escape wheel and left free to be impelled to the left by its spring, but meantime the stop shoulder on the tabulating member or segment has gotten in position to arrest the movement of the carriage, alining up for this purpose lly from the axis-of the fellows. and when the shaft is same distance radia shaft as its turned the e der after the other stop on the carriage. ing the segment to uppermost stop shoulder 14 on is in line with the carria' riage is free'to move, stop will strike the tab the carriage will be fleet is to bring one stop shoulinto the range of the For instance supposbe turned so that the the segment ge stopand the carthen said carriage ulating stop 14 and I with the stop arrested but if the segon the carriage.

It will be seen, that by reason of the concentric part 30 of the arm 29 the-arm 28 when depressed to disengage the carriage ment continues its s the carriage stop will the left striking the sh but when the segment ing movement then p by step to oulders in succession ceases in its swinging will be held down in this position thus ma1ntaining the carriage free while the tabulating segment is continuing its movement if this is necessary to bring the cagriage to the desired point. A

1 If the pointer 25 is movedto the million mark the first shoulder or stop on the tabulating segment is brought into range of the carriage stop and the carriage being released will be arrested thereby. The lev'er movement the earring shoulder on it will be arr the position of the as will be more e stop by striking the cut then in line with ereby, thus determi carriage for tabul particularly described The rock shaft is op 15 thereon and a ra with said gear by of the brackets, th

by drawing the at the pointer 25 tabulati'ngstop- It will be obvious that hand lever 21 forward so th moves over the dial 24 the f the hand lever 21 is operated .over the entire dial the segment will be swung and the carriage will be released as before and the carriage stop will engage in succession each one of the stop shoulders on the tabulatin segment, the carriage performing a in the direction g its stop shouln the paper carsegment 10 will be turned of thearrow Fig. 1 to brin ders in line with In order to set the paper carriage with its step step movement while the segmentis swinging.

It will be understood that in adjusting the carriage for the tabulating work the said carriage is stopped by the shoulder on the tabulating segmentjust one letter space in advance of the position it is to occupy and then when the tabulating segmentis returned to normal position the carriage escapement is thrown into engagement with under the action of i gaging act-ion takes with the swinging mo ing segment and fro This inecha arm 26 fixed'on the sh isfixed another arm 28 in range of an arm 29 fi This arm has a portion with its axis of rotation arm 28 is curved to cerr'e \Vhen the sh gear connectio ts spring.

The main drum will thus be turning against the opposition or resistance of the spring in the supplemental drum which will thus act to reduce the impact of the carriage.

l/Vhen' the tabulating lever is moved back to normal position the detent 39 will be released from the ratchet 37 and the supplemental drum together with its shaft and the ratchets thereon will then turn as one body without resisting the action of the main spring.-

In tabulating it will be understood that the tabulating lever need not be held forward but is simply released after it has been drawn forward to the proper point on the scale.
