METHOD AND APPARATUS FOR THE ALIGNING oF TYPE CARRIERS.

Application il'ed March 25, 1926, Serial No. 97,302, and in Germany April 2, 1925.

This invention relates to a method and apparatusl forv the aligning of type carriers assembled to form a line of type especially a justified line of type. The assembling of the type carriers to form a line may be performed in any suitable manner such as by means of a typewriting machine or a type-setting and printing machine or a type-` setting and casting machine.

The invention consists primarily in restricting the movability ofthe type Carriers to a certain extent, aligning the type carriers in their restricted inovability and the-n positively pressing thetype 'carriers together. The extent of the restricting of the movability is such, that the aligning of the line formed by the type carriers may be performed without an essentially greater eX- pense of power, while the type carriers are prevented from moving with respect to each other during the following treatment of the line such as justifying; the justifying preferably is performed by shortening the line to the desired length, whereby the primary length of the line is made greater than required by enlarging the distance between each two words and/or between each two type carriers.

A justifying device adapted to perform this method of justifying is more particu-- larly described in Letters Patent 1,608,017 dated November' 23, 1926. The method for aligning type carriers assembled to forma line by means of the above mentioned justifyin g device especially is performed by firstly restricting the movability of the type carriers by shortening the line to a certain extent, then aligning the shortened line and then further shortening the set up liner to its definitive length. The word typev carriers means carriers of patrices, matrices, type bars with one or more characters andthe like. When the type carriers are to be inked with colours by means of inking rollers or the like it is allowable in any case to effect the final inking after the justifying of the line. If an aligning means is employed which is reciprocating at each aligningoperation parallel to the direction of the lines the inking mechanism mayy advantageously follow the spacing means. and at least after the final closing of the line may again be guided firmly over the line.. The preliminary closlng may for example be ensured by providing yielding tension or compression means in the devices which bring together the closing device to the desired length of line.

Hereby excessive strain or even destroying of the closing device is prevented, which otherwise wou-ld occur if for instance more type carriers have been introduced into the device than necessary, so that the set up line is longer than admissiblewith respect -to its later shortening.

The moving of the closing device may be effected by means of a driving wheel adapted to be coupled with a constantly running motor or to be turned otherwise. The driving mechanism for example. ma be like that described in the pending app ication Serial Nok 628,514, filed March 29, 1923.

The inking roller preferably receives its ink from an ink distributing device as described in the pending application Serial No. 628,514, filed March 29, 1923l for grinding fat colours..

They device. according to my invention 1s able to work in only three phases and in less than onev second.

The invention is. illustrated by way of example in the: accompanying drawings in which.:

Figure 1 is a diagrammatic side elevation partially in section of a device according to the invention.`

Figure 2 is; a. plan thereof, and

Figure 3 a view from the left of Figure 2.

Fig. t shows a spacing member;

In the drawing A.z denotes a ratchet wheel which can be coupled to a source of power suchV as a continuously rotating electric motor and which then rotates in the direction of the arrow shown.

The wheel A2 is provided with a partially eccentric` groove A6, which is engaged by a projection VSt of a double armed lever St1 pivotally mounted in the machine at P. The other end of said lever is shaped in the form of' a fork adapted to receive a pin Q, on a wheel Stg. This wheel is only toothed on a part of its: circumference and adapted to be brought with its toothed partv intoy engagement with. the ratchet wheel A2. On the wheel St, an arm St3 isV fastened,` which is pivotally connected to a bar SQ.. The. latter is fastenedv to.` a bar' St5 crossing the machine and: adapted to be, moved in the direction of arrow R. St,3 isa rod carrying a series of small levers S2512 and engaging a pusher Sto.. H12 is a magazine adapted to be moved into different heights and containing a plurality of type-carriers, each provided with a series of characters. The type-carriers preferably are formed by type-bars as shown at Y21 (Fig. l). The magazine also contains the well known spacing members, one of which being shown in Fig. 4 and consisting of a strip of metal w provided with a flat spring The flat spring Z) is fastened at one side of the strip w and only at one of its ends as shown at c. This form of resilient spacing members is well known in the art. The number of the magazines H22, of the pushers Sts and of the rods St13 corresponds to the number of characters, which the line to be printed by means of the machine may have. Y23is a table for bearing the typebars Y22 and spacing members, after they have been moved out of the magazines so as to form a line of type.

The above described arrangement is shown and more particularly described in my co.- pending application Serial No. 628,514 tiled March 29, 1923,.

The manner of operation of the aforesaid machinery is as follows:

On each of the rods St13 a lever S1514 is moved into a position according to that of the lever Stm. This is effected by means of the striking of the key in a manner not of importance in connection with the present apparatus and more fully shown and described in Letters Patent 1,466fl91 dated August 18, 1923. Now the wheel A2 is coupled to a source of power (not shown) and rotated in the direction of arrow T (Fig. l).

Hereby the eccentric portion of the groove AG engages the projection St and moves the lever Stil, so that the wheel St2 is rot-ated and is brought into engagement with the teeth of the wheel A2. This wheel therefore rotates wheel S162 and moves the bar SS in the direction of arrow R by means of parts St., and Sty The bar S255 strikes the Ymoved levers St14a and takes them with it, whereby the pushers StG are moved in the same direction. The parts Sz?7 of each pusher enter the magazines and each move a typebar Y21 or a spacing member out of the magazines. The typebars and spacing members rest upon the table Y23 and form the lineof type. A closing or justifying device Y1 is arranged on the said table. The justifying device as shown is the same as that described in the Letters Patent 1,608,017 dated November 23,

and YG schematically represent the stepped longitudinal members more fully described in the specification of Letters Patent 1,608,- 017. These members serve for spacingl the plates, Y2,w'hich are `freely movable, arranged on the table Y22, at a certain distance apart from each other in one direction of movement of the device. The movement of the outer plates Y8 and Y4 is effected by means of the apparatus hereinafter described.

On the ratchet wheel A2 is provided a .stop A21 which can strike aga-inst a rod Sl, as shown in dotted lines in Fig. l. The rod Sl runs in guides and is moved during lthe further movement of the stop A22 in the direction of the arrow shown so, far that it assumes the position shown in full lines. The rod S1, is provided with teeth which imesh with teethon a wheel SW The shaft of the toothed wheel So extends transverselj,y through the machine and carries on the other side of the machine, that is to say, on the left hand ,side looking from the left in Figure 2, a similar toothed wheel notshown with which there meshes a second rod S100 provided with teeth. The latter rod also has other teeth which mesh with the teeth on a horizontal toothed wheel S2. On the shaft S3 of this toothed wheel `is mounted a crank arm S2 which is 'pivotcd to a rodS22. This rod S51 may be pjivoted directly to the member SG which runs on guides and is conlnected with one outer or thrust plate Y2 of the closing device. In the drawing, Fig. 2 a different constructional form is however illustra-ted in which the rod S5, is hollow. In the hollow rod S51 is slidably supported a rod S52 which is pivoted to the member SG. The rod S51 has a collar S53 while the rod S52 has a pin S52 projecting on both sides. Between the members S53 and SM is located a spring S55. The member SG is provided with teeth which mesh with a toothed wheel S7 which is journaled in the guiding rail of the member SG. On the side opposite to the member SG is arranged a rack S3 which likewise meshes with the toothed wheel S7 and .is rigidly connected with the other thrust or outer plate Y3 of the closing device.

A22 is a stop following the projection A4, and is adapted' to move the rod Sl out of the position shown in full lines a certain distance further in the direction of the arrow so that the end of the rod Sl takes up the position shown inrdotted lines. S2,1 'is a stop or tooth at the end of a rod S12 which has a rack at the other end. This rack meshes with a toothed wheel which is lin one piecel with the above-mentioned toothed on the same shaft.

The method of working of the apparatus is as follows:V i

By the above-mentioned displacement of IUS lSCh

the rod Sl by the stop A41 out of the position shown dotted into the position illustrated in full lines the toothed wheels S9 located on both sides of the machine are r-otated and the rod S1 located on the 4left hand side of the machine is also moved. This in turn results in rotating the toothed wheel S2 and with it its crank arm This movement takes place in a clockwise direction from the point of view of Figure 2 and has the result that the member SG is moved from right to left, and, through the medium lof the toothed wheel S7, the member S8 is moved from left to right, that is to say, in the opposite direction. By this means the outer` plates Y3 and Y1 of t-he closing device Y1, ywhich were previously at the distance from one another denoted by 1 in Figure 2, are moved nearer together to such an ext-ent that the distance between them corresponds to the distance marked 2. The Y2 plates of the closing device are thus moved nearer to one another and consequently the lline formed by the type bars is provisionally justified. In this position of the closing device the type bars are hindered in their free movability in the longitudinal direction and also in the transverse direction in such a way that theycan still be displaced relatively to one another by the aligning means Y22 which is'led away over the line and whichengages in grooves in the ty Je bars Y21 (Fig. l) in such a way that the line formed is aligned, but that after this aligning, during the final closing of the closing device which now follows, they can no longer shift relatively to one another. The possibility of the type bars shifting relatively to one another during the aligning by overcoming a certain resistance has the advantage that during the aligning the type bars do not`suflier too severely. ent connection between the rods S51 and S52 also renders possible a certain yielding of the closing device.

in such a way that the outer or thrust plates- Y3 'and Y,1 are brought to the distance 3 from one another. This takes place owing to the further displacement of the rod S1,effected by means of the stop A12. i

The return movement of the vclosing device into the position in which the outer plates are at the distance l vfrom one `another is effected by the stop A 1 1 bringing the stop S11 out of the position shown in full lines into the lowermost position shown in dotted lines.

This movement results, owing tothe rack teeth of the rod S10, in the reversed rotation of the toothed wheel S9 and of the device associated therewith.

During this movement the plates Y2 are The resili-` spaced at a certain distance apart from each other by means of 'the members YE, Y.6 :as described in Letters Patent 1,608,017 above mentioned. I l

An inking device F12 may follow the aligning means Y22, preferably in .such a way that Aat least during the return 4of 4the aligning means, that is to say :after the l'closing device is finally closed, an inking is again effected so that the inking takes place with certainty when the closing :device holds the type bars fast in their final position.

The device for moving the aligning vmeans and the inflring vdevice in the manner above described is shown in the arrangement `which 'is more fully described in the copending applications Serial Number 628,514filed March '29, 1923 and Ser. No. 114,783 rfiled June 9, 1926.' The aligning device Y22 and the inking device F12 are shown to .be connected with each other and movably arranged on two guide-rods Y24 and Y25. The ymovement is effected by means of a flexible member F2, which is connected to the part Y26 surrounding the rod Y25. The vends of the flexible member F9 (a chain or the like) are woundupontwo drums FR in opposite glerections in such manner that if the drums fa e'rotated in the same sense, kthe flexible member is wound up y'by one drum and vsimultaneously unwound from the other drum. Hereby the flexible member is `reciprocated `and moves the part 'Y2G to and fro. The drums are fastened-onthe ends of a rotatable shaft F20, upon which a toothedwheel F21is mounted. F1 isla disc provided'with a cam-groove TF2 and fastened upon a yshaft F crossing `the machine. On the other end of theshaft 'F10 a-toothed wheel D2 is mounted which `has a shape similar Ato that described with respect Zto the aforesaid wheel S752 and adapted to berotated by wheel A2 inthe same manner as `wheel St2. F4 is a lever pivoted in the vmachine at'F5 Vand carrying a toothed segment F6, which engages a toothed wheel F7. fThe wheel F7 is provided with two rings of tee'th, one of them being in engagement with the teeth vof the wheel F81. F2 `is 'a projectionor roller arranged upon lever FlVL kand engaging the groove F2. F11 are rollers mountedin the machine in a manner :not shown, which guide `-the flexible member F9. yThe rotation of wheel 4D2 imparts a vswinging motion to the lever F4 and effects thereby a similar movement of the shaft F;
