ALININ'G APPARATUS FOR PRINTERS FORMS.

Specification of Letters Patent.

Patented Oct. 15, 1918.

Application filed July 3, 1916. Serial No. 107,217.

To all whom it may concern:

Be it known that I, FREDERICK A. PooLn, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvements in Alining Apparatus for Printers Forms, of which the following is a specification.

My invention relates to improvements in alining apparatus for printers forms and relates more particularly to that class of apparatus of which the device shown in United States patent to Rowse No. 1,133,822, issued March 30, 1915, is an example.

The object of my invention is to provide an apparatus of the class described, so organized that the locking of a number of page forms into a sheet form layout may be accomplished rapidly, accurately, and without the necessity of troublesome mechanical manipulations or mathematical calculations; to provide an arrangement of the class described, the construct-ion of which is such that it will accommodate all sizes of pages having any desired widths of margin with out the necessity of substituting or changing parts of the apparatus or using different sized appliances; to provide a construction which is simple and economical to manufacture; and, in general, to provide an improved construction of the character referred to.

In the drawings which illustrate a preferred embodiment of my invention Figure 1 is a .plan view of a lock-up stone equipped with my improvements;

Fig. 2 is a section taken on the line 22 of Fig. 1;

Fig. 3 is a plan view of one of the adjustable mountings for the alining guides;

Fig. 4 is a section taken on the line 44 of Fig. 3;

Fig. 5 is a fragmentary enlarged view of the left-hand end of Fig. 4;

Fig. 6 is a section taken on the line 66 of Fig. 3; I

Fig. 7 is a perspective view of the gage bar; and

Fig. '8 is a'fraginentary side elevationof Fig.

Referring to the drawings, 10 represents the lock-up stone or imposing plate which forms'a bedortable upon which the alining and registering of the forms is carried out. Said lock-up stone is a substantial cast iron rectangular slab suitably supported'at a convenient height, for instance, upon a printers cabinet, and planed off smooth on its upper surface. The chase in which the page forms are to be locked up to constitute a sheet form is indicated at 11 and the page forms (in the present case sixteen in number to form a sixteen-page book) are indicated at 12 to 27, inclusive. In the drawing I have shown the page forms locked up in the chase, but of course it should be understood that said forms are not finally locked up in the chase until the alining apparatus has been utilized to accurately position the page forms.

Around three sides of the plate are permanently secured by cap screws or other devices three

flat bars

28, 29 and 30 which project above the surface of the lock-up stone, as shown in Fig. 2. On the right-hand side of the plate there is also detachably mounted a similar flat bar 31 which may be removed from the stone by slacking off the

cap screws

32, 33, 34 and 35, thereby enabling the bar 31 to be lifted vertically upward and removed bodily. The devices which constitute the important part of my invention are carried on the upwardly projecting portions of the

bars

28, 29, 30 and 31. 36 represents a longitudinal mounting block made of machine steel or other suitable metal, in the under side of which is cut a groove 37 which fits over the upper edge of one of the

edge bars

28, 29, 30 or 31. Midway of the length of the block a threaded hole accommodates a set screw 38 with a milled head 39 by which the position of the mounting block 36 along the edge bar may be adjusted and held. In the upper face of the mounting block is out a rectangular groove 40 the ends of which are closed, the top of the groove being open to accommodate the sliding alining guides or gages 41 and 42. Said gages 41 and 42 are rectangular in order to fit and slide in the groove 40. As shown in Fig. 6, the upper ends of thegages 41 and 42 project above the level of the top of the mounting block 36 and are inclined downwardly toward the lock-up stone and are provided with saw cuts 43 in order to accommodate alining strings, as shown at 44.

The gage blocks 41 and 42 are tapped respectively with a left-hand and aright-hand thread'in order to accommodatecorrespondin'g left-hand threads 45 and right-hand threads/46 on a micrometer screw 47. As shown best in Fig. 4, said micrometer screw is reduced at its right-hand end to form a of the screw for adjusting purposes is accomplished by means of the knurled head 52 which is secured upon the extended end of thestem 50 by means of a diametric pin 53. Improper movements of the adjusting screw are largely prevented by means of a conical headed pin 54 arranged to slide in a short cylindrical bore 55 under the influence of a coil spring 56 which forces the conical head 57 of the pin 54 into one or other of a pair of diametrically opposed conical recesses or countersinks 58 in the end of the mounting block 36. It will of course be readily understood by those skilled in the art that the mounting block 36 must be made in two or more parts in order to permit the insertion of the micrometer screw, although it is unnecessary to describe such sectional construe tion in detail. 7 7

Each of the gage block mountings 36 is provided on its upper surface with a scale 59, preferably in inches and sixteenths, the zero point of which coincides with the center of a gage hole 60 positioned centrally between the said kerfs 43 and gage blocks 41' and 42. Such symmetrical relation ofthe blocks 41 and 42 with reference to the gage hole 60is always maintained by reason of the fact that the

threads

45 and 46 have the same pitch, each of the blocks therefore moving an equal amount to or from the center when the milled collar 52 is turned. 7 a

In using the apparatus, the page forms are roughly placed in position on the lock-up stone, the bar 31. is applied, and a pair of strings are stretched across the permanent

orend gage blocks

61, 62, 63 and 64. These end gages 61, 62, 63'and 64 are single-ended since they accommodate only one string and are so'positioned that the

strings

65 and 66 cross each other exactly at right angles when the gage blocks on said end mountings are properly adjusted. Scales are marked on the

end blocks

61, 62, 63 and 64 similar to the scales 59 on the'double gage mountings, gage holes being also drilled at the zero points of said scales.

In setting the strings65 and 66the operator, by means of the micrometer screws, adjusts the gage blocksin. such position that the strlngs'or saw cutsin the gage blocks willjbe located at distances from the gage holes corresponding to the allowance'to be made for margin and trimming between the edge of the paper and the boundary of the printing area. Having properly adjusted the

gages

61, 62, 63 and- 64 for the

strings

65 and 66, the operator sets the gage bar 67, Fig. 7, to the proper distance between the edge of the sheet which is to be printed and the point where the first fold of said sheet is to be located. Said adjustment of the gage bar 67 is eflected by means of a sliding clamp 68 which may be set by a knurl screw 69'according to a scale 70. The fixed gage pin 71 is then inserted in the end block 64 and the properly adjusted slidable gage pin 72 is inserted in the mounting 36 by sliding .the latter along the edge bar 29 until it is in such position as'to permit the entrance of said gage pin 72. The thumb screw 38 is then turned to clamp the mounting 36 securely in position on said bar. The other gage block mountings on the side edges of the plates are similarly clamped in position, after which the adjustment of the gage bar is chan ed to correspondwith the width instead 0% the length of the page, after which the end gage block mountings are clamped in position. Having thus .utilized .the gage bar 67 to set the gage block mountings around all foursides of the lockup frame, strings are stretched in the kerfs.

page formsto be locked up into proper. reg1stering position, as shown.

In View of the foregoing, it will be seen that my construction is of great benefit and advantage to the practical printer in en ablinghim to lock up a large .number of page forms in each chase with a minimum of trouble or opportunity for mistakes. Provided that the preliminary location of the gage block mountings has been properly effected, which is an easy matter with the gage bar, the only thing then necessary is to adjust all of the micrometric' mountings an equal amount. With my improved -micrometric gages there is no possible opportunity for locking the gage strings at different distances from the fold in the paper,

assuming ofcourse that the printer has properly calculated the distance between folds and has set hisgage bar accordingly.

The manipulation of the apparatus will be to use in connection with lock-up stones, but

may conceivably be'used in connectio'nwith other devices or apparatus by means of which the page forms" are locked up into a sheet form. The term lock-up frame as used in the claims is intended to cover all devices designed for the general purpose of a lock-up stone as used in connection with a chase. I consider within the scope of my invention any arrangement by which the gage-string supports are properly coordinated with the chase or holder for the forms. Such lock-up frame on which the gagestring supports are founded need not necessarily include the lock-up stone as ordinarily employed.v

The described details of construction merely illustrate the application of my invention, the scope of which must be determined by reference to the appended claims.
