MEANS FOR LOOKING AND ALIGNING TYPE SEGMENTS.

Original application filed March 28, 1917, Serial No. 158,142. Divided and this application filed April 8, 1918. Serial No. 226,498.

T all whom it may concern:

Be it known that 1, WILLIAM "W. LAsKER, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Means for Looking and Aligning Type Segments, of which the following is a specification.

This invention relates to a printing tabulator of the kind adapted to be controlled by perforated cards, and relates more particularly to matter divided from my copending application Serial No. 158,142 filed March 28, 1917, for printing tabulators.

The invention herein described relates particularly to the means for locking and aligning the type segments of said printing tabulator; and, therefore, only as much of the printing tabulator is described herein as is necessary to show the connection between the matter of the original application and the matter divided out and described herein.

While herein and in said application minute details of one of many possible embodiments of the invention are described, the invention is not limited to these since various changes may be made in the details of construction and combination without departing from the spirit and scope of the invention as claimed.

One object of the invention is to improve generally apparatus of this kind.

Another object of the present improvement is to construct a printing tabulator having an improved form of locking and aligning mechanism for the type segments, which will be efiicient in operation and economical in structure.

Still further objects and advantages of the present improvement will be set forth in the following description and drawings in which,

Fig. 1 is a side elevation of the printing tabulator constructed in accordance with my invention.

Fig. 2 is a detail view of the locking and aligning bar.

Fig. is a side elevation of a type segment and its actuating mechanism.

Fig. i is a plan showing the locking and aligning bar engaging the segments.

Fig. 5 is a side elevation of the stop pin box, showing shutter latches for holding the stop pins set.

6 is-an end elevation of Fig. 5.

In the said co-pending application means are shown for feeding perforated cards to an analyzer comprising a reci rocating in box provided with the pins a a ted to eel the cards and on finding per orations in the cards to pass through such perforations and to raise registering stops corresponding to perforations, the naught stop being normally raised and adapted by suitable connections to be depressed by the raising of a numeral registering stop.

Referring more particularly to the drawing of the present application, there are shown a lurality of numeral registering stops 10 Fig. 3) of the kind just mentioned. These stops 10 are arranged in rows, and associated with each row is a naught stop 11 and a reciprocating rack bar. Each rack bar 12 is provided with a downward projection 14 adapted to engage the rear face of a raised stop 10 or 11 as the rack is reci rocated forward (to the left, in Fig. 3) y a transverse bar 15, as will be explained.

This transverse 15 engages a drive shoulder 16 on a pivoted bar 18 pivoted at its forward end to the rack bar 12 and yieldably held in raised position by a spring 19 strained between its rear end and a bgacket 20 on the rear end of the rack bar 1 Said pivoted bar, is normally held raised, as just stated, so that the shoulder 16 will be engaged by the transverse rack bar 15. Said pivoted bar 18 is lowered from the normal position to the position shown in Fig. 3 by means of a small lever 21 pivoted at 22 to the rack bar 12, and provided with a slot 24 receiving a pin 25 fixed to the pivoted bar 18. The lower end of the lever 22 engages (as the rack bars and said levers are brought forward) whichever stop 10 or 11 is raised. At this instant, said lower end is raised and the slotted end of the lever 21 is lowered thereby lowering the pivoted bar 18 and the shoulder 16 thereon, thus permitting the transverse bar 15- to more on free from said shoulder, the rack bar 12 being stopped by its shouldered projection 14 engaging behind said raised stop 10.

WVhen the transverse bar 15 moves rearwardly, it engages the shoulder 26 formed on the rack bars 12 and moves all of the rack bars to their rearward position. This rearward movement takes place after the printing has taken place as will be explained.

The bar 15 which as heretofore described, is for the purpose of reciprocating the bars 12 and 18 is itself reciprocated in the following manner, reference especially being made to Fig. 1. The bar' 15 which is rectangular in cross section is rigidly connected at each end to a slide 27, which is reciprocatable between rollers 28 forming guideways therefor. A slot 29 is made in each cheek plate 30 of the frame of the tabulating machine, and in this slot 29 is received a roller 31 revolubly mounted on the rear end of the said slides 27. The front end of the slides 27 are provided with horizontally extending pins 32, which are received in slots 33 formed in the upper ends of levers 34, the lower portion of which are triangularly shaped, one corner being pivoted to stud shafts 35, carried by each cheek plate 30. The other corner of the triangular shaped levers 34 carries rollers 36 which are arranged to roll within cam grooves made in the cam 38 on the shaft 44 (Fig. 4).

Returning now to the reciprocating bars, the top edge of the forward portion of the said bars 12 are provided with gear teeth 49 (Fig. 3) whichare in mesh with a gear 50 secured to type segments 52, which have bearings on a transverse shaft carried between the cheek plates 30. Said segments have an are shaped rear edge provided with gear teeth 54 which will hereafter be described. The front edge of the segments,

52 are also made are shaped and have mounted thereon ten type 55. Reading from the upper edge of the type carrying portion of the segment, the type carried thereby read in sequence, the first type being zero, the next 1 the next 2 etc., the last type on the segment being numbered 9.

Vhen the pins 10 have been set by perforated cards, as explained, and the transverse bar 15 has caused the forward movement of the rack bars 12 until they are stopped by the raised pins 10- or 11, the type segments are stopped with the t pc in printing position in accordance with the position of the raised pins 10 or 11. At this instant paper carried on a suitable paper carriage is pressedagainst the typeand the printing takes place. After the printing takes place the paper is fed, one or more line spaces and is ready for another imprinting. A suitable paper carriage is described in, said co-pending application.

After all of the type segments have been set by the stop pins in position to print data transferred thereto from the cards, means is provided for locking and aligning the type segments so that they may not move during the printing operation. This locking and aligning means will now be described.

A lever 72 (Fig. 1) is provided. having a bifurcated lower end 73 which straddles the main drive shaft 44 which provides the driving means, for the entire type setting and calculating mechanism. This lever 72 is provided with a pin 74 upon which is rotatabiy mounted a roller 75 which is arranged to roll within a cam slot 76 of a cam 77 (Fig. 4). The extreme upper end of the lever 72 is provided with a knife shaped transversely extending arm 80 slidably mounted within a slot 81, within the cheek plates 30. knife shaped member 80, which is termed a detent, are arranged radial to the gear teeth 54 of the type segments and lock said segments from moving, and line up the type.

carrier thereby.

The lever 72 is also connected to suitable Both the slot 81 and the mechanism for returning all of the numeral stop pins to their normal position at the same time raising thena-ught stops 11.

As these mechanisms are described in detail in said copending application, they need be here described only briefly as follows:

Means are provided for anchoring in raised position the various stop pins 10 as they are actuated, and for holding the zerov stop 11 in position for stopping or permitting to pass the corresponding type setting and tabulating elements. This anchoring means comprises shutters 186 (Figs. 5) pro vided with end lugs 187 extending through openings 189 of the end plates 190. By

' means of these lugs 187 the shutters 186 are adapted to rock relative to the end plates. The upper edge of the shutters have an inclined edge 191 and a forwardly extending arm 192 that is turned at its extreme end to form a stop 193. Each of the shutters 186 is disposed adjacent to one row of stop ins 10 with its inclined edge 191 exten ing toward the pins. In order that the stop pins 10 and zero stops 11 be anchored by the inclined edges 191 they are provided with upper and lower notches 194 and 195, each forming at its upper edge a shoulder adapted to engage the inclined edge 191, so that the sto as 10 will be supported on such inclined ec ge 191.

The lower edges of the notches are inclined to form calm faces over which the edges can ride with facility when the numeral stops 10 .are raised. As one of the sto s 10 is raised the edge191 of the shutter w-il engage the cammed face of the upper notch and will be forced outwardly sufficient to put the springs (hereafter to be described) which actuate the shutter 186 under suflicient tensionflto cause the said shutter to springwithin the lower notch 195 when it has cleared the'said ram face, and at 'the same time to move the shutters a suflicient distance to releasexthe zero stops The edge 191 upon lodging within the lower notch 195 will maintain the stop 11 in a raised position' For normally resiliently maintaining the saidshutters' in engagement ,with thestops 11,- the springs 196 are provided, which are secured to the upper edge of a reciprocating plate 197 and extend downward into en- 'gagement with the extensions 193: as shown in Fig. 6, said springs 196- exercising a lateral pressure on the shutters 186 to press them into engagement withthe stop pins 11,

v The rear side plate 190 is provided with openings198,,through' which the said exvtensions 192 pass. The extensions 192 also pass through ,reces'ses 199I formed at the loweredge of'the reciprocatable', plate 197. The reciprocatable platefl197 is provided screws 201, to permitfthesliding ofithe plate 197. For normally maintaining the'plate The plate 197 "s tension 209 which extends through thechee plate 30 and has a lower cam face 210 I for engagement, by theshutter release arm 211. The openings 199 in the side plate 199 are of suflicient width to permit the lateral movement of the extension 192, and the extensions 192'normaiiy rest against one edge of the openings 199.

The release arm 211 is intermediately fulcrumed on a screw 212 (Fig. 1) in the cheek plate 30 and is provided at its motive end with a slot 214 receiving a pin 215 fixed on the side of the lever 72. I i

As the lever 72 moves downward to effect the locking and aligning of the type segments by the bar 80, the slotted end of the arm 211 is lowered and the active end of the arm is raised into engagement with the lower cam face 210 (Fig. 6) thus throwing back the plate 197 and forcing the sides of the recesses 199 against the extensions 192 and forcing back the shutters 186 from contact with the stop pins and releasing the latter to be lowered under the action of the springs 24:0 later to be mentioned.

The zero stops 11 are normally disposed in. raised position and whenever a stop 11 is actuated to theraised position, simultawith recesses. 200 through which lextend' by'thelbar 80,

also provided with an eX- J row will be lowered. In order to accomplish this result an elongated lever 222 (Fig. 3) is provided for each row of stops 11, which lever is provided with a plurality oflugs 223 arranged in a straight line and extending into one of the recesses 22401 the stop pins 11. Thefront'ends of the levers 222 are pivoted on a shaft 225 which is supported by the cheek plates 30. The rear ends of the lever 222 are provided with lugs 226 which slidably and pivotally engage in slots 227 at the rear ends of the links 228 pivoted on a shaft 229 supported bythe cheek plates 80. The front end of the ,links 268 are provided with lugs 230 which are arranged to slide within a recess 231 formed in the rear edge of thenought stop 11.

Suitable springs 240 are provided for the purpose of normally holding the levers 222 down and raising the nought stops 11.

WVhen-on'e of the stops lOis raised, the actuation of the lever 222 by means of the cooporationof the slot 224 of the stop, with the zero stop 11 of-the row in. which the numeral stop pin 10 has been raised.

I Inview'of the foregoing, itwill be'noted tliat the lowering of the numeral stop pins 11 andjthe raising of the zero stops cannot take placeimtilthe' type segments are locked at the same time. causes-the locking of the segments. Inthis way there is no danger that the stoppins be lowered before the segments are locked.
