ASSEMBLER GUIDE FOR TYPESETTING MACHINES Filed July 13, 1935 Patented Oct. 20, 1936 MACHIN George Rupert 'Schladetzky, Omaha, Nebr. v Application July 13, 1935, Serial No. 31,255-

12 Claims. (01.199-28) This invention relates to the class of type setting machines and pertains particularly to an improved element in a machine of the type known as Linotype. The primary objectbf-the present invention is to provide an improved assembly mechanism for a type casting machine by means of which the transposition of letters of a word is prevented in the event'that the operator of the machine works or operates the same at too great a speed.

In typesetting machines of the character referred to, the assembling of the matrices can only progress at a prescribed rate and if the operator of theimachine increases the speed at which he releases the matrices, it frequently happens that a spaceband will be introduced aheadof a matrix forming the last of a Word. forming group instead of behind the same so that the last letter of the word will be printed in front of the next succeeding word.

The presentinvention is designed to overcome the foregoing difliculty by moving the matrix from the inclined position which it assumes in approaching the assembler, directly to a vertical position without being retarded by the chute finger so that a released spaceband cannot interpos e itself between the last matrix going to make upa word group and the preceding ones.

Another object of the invention is to provide an adjustable chute finger which works as an auxiliary to an improved form of the chute finger which at present is employed, "whereby the said auxiliary finger may be adjusted relative to the assembler belt in accordance with the thickness of the type font being used.

Still another object of the invention is to provide an improved chute finger which is adapted for forward and rearward movement.

The invention will. be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient'features of the invention as expressed in the appended claims. r

Figure 1 illustrates a portion of the-assembler mechanism of a type casting machine wherein is shown one of the two pulley wheels 1 over which the assembler-belt '2 passes; The numerals 3 indicate certain of the chutes nearest the assembler proper through which the matrices pass to the assembler belt while the numeral 4 indicates the spaceband chute through which the spacebands pass to the assembler;

A portion'of the assembler structure is "designated by the numeral 5, in the lower part of which the assembling elevator -6 is disposed for the reception of the matrices and space'bands which are shifted into the proper position therein by the star-wheel The numeraI B indicates a guide over which the matrices passlfrom the assembler belt tothe star-wheel and above which the element known as the chute finger is disposed.

The present invention constitutes an improve-' ment inthe chute finger at present in use and is indicated as a whole by'the numeral 9. This device, consists, of the plate l ll which is firmly secured tothe wall of the machine between the spaceband chute and the matrix chutes in the manner illustrated. At. the end of the plate nearest the spaceband chute, there is secured the improved chute finger which is indicated as a whole by the numeral '11 and .which comprises three parts in the form of arms which are connected together in .end to end relation. The upper arm, which is indicated by the numerallZ, has an edge flange l3 whichis secured to the plate In and at its lower end a pair of .apertured ears l4. These ears are in spaced relation, as shown, and between them are disposed the spaced apertured ears I5 of the intermediate arm 16. The lower corners of these .earsl5 are rounded, as indicated at I'Lso that the arm I6 may swing in one directionupon thepivot pin 18 which passes through the alined apertures of the ears mally maintains these two arms in parallel relation.

At the lower end of the intermediate arm are the two spaced apertured ears 2!] between which are located a similar pair of spaced apertured ears 2| formed integral with the upper end of the lower arm 22. The lower corners of these ears 2| are rounded, as indicated at 23, so that the arm 22 may swing in the opposite direction from the arm 16, upon thepivot pin 24, which passes through the alined openings of the ears 28 and 2|. coil spring 25 which normally maintains the arm 22 in the desired relation with the upper arms.

This arm 22 is normally angularly disposed with respect to the upper and intermediate arms and terminates at its lower end in the spaced tines 26 which extend beneath the spaceband chute 4 and which have their free ends curved downwardly toward the assembling elevator, as indicated at 21. These down-curved tines have their ends extended slightly into the assembler mechanism.

Disposed behind the chute finger H is an auxiliary chute finger 28 which is in the form of a relatively long flexible band of material, preferably springcopper. This is attached at its upper end to a yoke 29 which carries spaced ears 38 A through which extend a pivot pin 3| which has' one end secured in and extending at right angles from the face of the plate IN]. This yoke is oscillatable on the pin 3| and has integral with it the short tongue 32 which extends forwardly from the finger 28.

Secured to the plate It) between the yoke 29.

and the chute finger II is a post 33 which extends outwardly from the plate and which is threaded throughout to receive the interiorly threaded sleeve 34. This'sleeve 34 has formed on its inner end the cone 35, the apex of which is directed toward the plate It) and the surface of which is ribbed longitudinally and contacts with an edge of the tongue 32 across which it moves. By moving this sleeve 34 inwardly toward the plate [8 or outwardly on the threaded post 33, the cone will move against or away from the tongue 32 and so oscillate the same and the finger 28 which is attached thereto.

Adjacent the auxiliary chute finger 28 is a second and shorter auxiliary finger which is secured at one end to the bracket 29 and which is indicated by the numeral 39. This second auxiliary finger extends downwardly in divergent relation with the finger 28 toward the upper part of the matrix guide 8 while the larger auxiliary finger 28 extends down over and in spaced relation with the guide 8, being directed toward the assembling elevator.

It will be apparent that the actuation of the adjustment cone 35 will move the two fingers 28 and 39 simultaneously and by this means, the space between the auxiliary finger 28 and the matrix guide surface 8 will be adjusted in accordance with the thickness of the type font used.

.The form of the star-wheel illustrated in Figure 1 and indicated by the numeral 1 illustrates an improvement in this element which facilitates the passage of the spaceband from its guide into the assembler. These star-wheels have four arms, each of which is indicated by the numeral 36, each of which terminates in a head 31. At the present time, these heads are formed with their'outer ends at right angles to the sides or, in other words, have what are known as square ends. The operation of the wheel has been found This pin has mounted thereon the.-

to be improved by beveling or cutting ofi the opposite corners of each of the heads, as indicated at 38, so that each head appears as a point instead of square, as previously. With this construction, the spacebands are found to more readily descend to their proper places instead of striking on the end of an arm of the wheel as they frequently do at the present time.

In operation, the present improved matrix controlling unit causes the matrices to make only one movement from the 45 angle at which they descend to the straightening up or vertical position which they must assume in entering the assembler. The matrix, therefore, comes directly into the assembler without interference and as it. contacts the star-wheel, which forces it to the vertical position, it continues to move without interference to its .upper end and only touches the downwardly curving points 21 of the tines 26 of the chute finger. This contact of the upper end of the matrix with the downturned points of the tines 26 does not take place, however, until after the top of the matrix has passed the point where the spacebands descend. With theprese ent chute fingers, when the star-wheel comes in contact with the matrix, it causes the matrix to force the chute finger to move against the spring tension which holds it, before the matrix starts to come to its vertical position, thereby causing a slowing up of the progress of the matrix and allowing time for the spaceband to decend and enter betweenthe matrix and those which have preceded it instead of entering behind the matrix as it should do. With the present device, the auxiliary chute finger holds the matrix fiat against the guide surface until it is engaged by the star-wheel and its upper end is then quickly moved over to vertical position and into contact with the downturned ends 21 of the tines 26, as previously described so that there is no slowing up of its movement from the angular to the vertical position and the spacebands are not given time to fall into the wrong position.

By forming the guide finger or spaceband guide H with the double hinge, means is provided whereby the operator may readily insert special characters into the assembler by hand and in addition by disposing the tines at the lower end of the chute finger with the curved points slightly inside the assembler, the spacebands as they descend are kept in a vertical position until the star-wheel pulls them down to their proper places, thus doing away with the leaning of the bands which necessitates the operator pushing them down by hand before sending the matrix line to the mold.
