LOCKING-MEANS FOR PRINTERS FORMS.

Patented May 11, 1920.

Application filed September 5, 1919. Serial No. 321,810.

To all whom. it may concern:

Be it known that we, LOUIS J. REICHEL and l VILLIAM L. WARNER, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Locking Means for Printers Forms, of which the following is a description, reference being had to the accompanying drawing, which forms a part of our specification.

Our invention relates to means whereby printers forms may be firmly locked within the chase; the invention having for its object the provision of means more especially intended as an auxiliary to the main quoins; the means being particularly adapted for use in situationswhere the main quoins cannot be employed; and at the same time, they may also beused in conjunction with such quoins as enable the cuts or formsv to be tipped for the purpose of obtaining a perfeet register, especially where multi-colored printing is to be done. I

Our improved construction obviates the necessity of employing wads of paper, cardboard or plugs of lead, a practice frequently employed by printers to secure the necessary line adjustment of a form Our invention contemplates means which will permit adjustment ofthe forms on what may be ,which will onadjustment, while at the same time providing a proper bearing or firm hold on all sides of the out or form; the means being of such nature asto permit adjustment to practically any angularity within reasonable limits and yet at the same time provide firm and square contact being of such construction that it subjected during the operation of the press.

The ob ects and advantages of our 1mprovement will be more thoroughly comprehended fronr the following .detailed deelements of our improved means.

with the furniture and the forms or cuts, the means I will withstand the excessive vibration to which it-is Our invention relates to what may be called auxiliary or register quoin sections which are intended more especially for use in. conjunction with the main quoins which latter may be of any of the usual forms at present employed, as for example the type illustrated at 10 in Fig. 1; although the present invention is particularly adapted for use in conjunction with quoins of the type illustrated at 11 in Fig. 1 and which form the subject-matter of our application Serial No. 245,286.

In order to illustrate the adaptation and operation of our improved lockingmeans, we have shown in Fig. 1 a portion or section of a chase indicated at 12, provided with a form composed of a number of cuts or electro-plates indicated at 13, held in position in the chase by means 01": the usual furniture indicated at 14. Thevarious pieces of furniture are shown locked in place by the quoins 10 and 11; the former being of a well known construction and consisting of two wedge-shaped sections adapted to move endwise in opposite directions so that the enlarged or base portions of the two sections will be moved toward each other. The quoins 10 are not only restricted to situations where suflicient, space intervenes the furniture and the cuts or form, but are not capable for use in situations where the cuts or electro-plates require tipping, as illustrated for example in the lower right hand part of Fig. 1, in or- .der to secure the proper register in multicolored printing. In situations as last mentioned, the quoins 11 are employed because they not only permit of a wedging action, but the two sections of the quoin are also capable of a rocking movement on each other, to provide the necessary angularity for the cut .or plate; the quoin indicated at 11 being ofsuch construction that the two sections of the quoin will permit a half point adjustment, thus enabling. a perfect register to be obtained.

It is evident from the illustration in Fig. 1 that the margin or space intervening different portions of the forms or cuts and the adjacent furniture is such that the usual quoins cannot be employed and itis for this purpose that wc provide our improved locking means in the nature of the auxiliary members shown inv "perspective in Figs. 2 and 3 and which are more 'especially intended to be employed as complementary quoins arranged in opposing relation with the main quoin, as exemplified in Fig. 1.

The auxiliary or complementary quoin comprises the two members 15 and 16 shown in Figs. 2 and 3, respectively. The member 15 is formed in the nature of a right angular wedge-shaped section, having a flat longitudinal outer surface and an inner inclining surface; the latter surface being provided with transversely disposed grooves which preferably extend the full width of the section so as to provide a plurality of intervening projections or teeth 17, as shown in Fig. 2. The teeth 17 are preferably arranged throughout the length of the inner surface so as to provide a gripping surface for the complementary member 16 at various points on the inner surface of member 15.

The other or complementary member 16 is provided with an outer flat surface, while the inner surface is shown provided with a transversely disposed ridge or rib 18 at a central point intermediate of the ends of the member and extending from side to side. The inner surface of said member is sloped or tapered {in opposite directions from'the central ridge or rib 18. The ridge or rib 18 is preferably beveled, as shown in Fig. 3, so that when the two sections or members are brought into operative relation with each other, the ridge or rib 18 may extend intermediate of adjacent teeth 1? on the section or member 15. The sloping or tapered inner surfaces of member or section 16 will permit the section or member 16 to rock or tilt on the ridge or rib or in other, words permit the two sections to tilt on each other; the binding relation offected by. the ridge or rib with the teeth, however, maintaining the two sections or members in any adjusted relation induced by the angularity or tip given to the form or electroplate by the operator for the purpose of securing proper register.

As an illustration of the manner in which this auxiliary or complementary quoin may be employed, we have shown the same at 19 in Fig. 1, where it is disclosed in opposing relation with the other or main quoins; namely in situations where the space between portions of the form or cut is too small or narrow to permit the use of the large or main quoins. At the same time the adaptability of our improved auxiliary quoins to situations where the form or out is to be given a tilt or tip is clearly exemplified at the lower right hand corner of Fig. 1, where the out or plate 13 is given a tilt or arranged at an angle to secure the desired or necessary registration; a condition which frequently arises especially in multi-colored printing. The auxiliary quoin adapts itself to comparatively small or narrow spaces as is evident from its construction while at the same time adjusting itself to any angularity, due to the rocking or tipping relation between the two sections 15 and 16, which at the same time become locked-in the adjusted relation with each other against displacement; the outer faces of both sections at all times providing firm and comparatively large bearing surfaces against the form or cuts and furniture.

Our improved construction greatly simplifies the movement or adjustment of individual portions, especially in large forms consisting of many parts, without disturbing the general lock-up of the form; the locking means finding its own level, so to speak, whereby considerable time and labor in the work up, caused by the springing of the form, will be saved.

In order that the relation between the sections 15 and 16 may be altered or adjusted to a different point, we prefer to provide the section 16 with the projection or lug 20, extending from one of the longitudinal sides of the section and preferably at a point in alinement with, or in reality constituting a continuationof the ridge or rib 18. With the projection or lug 20, it is evident that when it is desired to readjust the means, the printer or operator may readily grasp the lug or projection 20, by means of pliers or otherwise, and cause the section 16 to be slid transversely from the opposing face of the section 15, to be forced into position at any desired point 011 section 15, by inserting the ridge or rib 18 endwise into the groove intermediate of adjacent teeth 17 on the section 15.

e have shown and described what we believe to be the simplest embodiment of the invention, which, however, may be susceptible of some modification, without, however, departing from the spirit of the invention.

What we claim is:

1. Means of the class described, comprising a pair of members, one member being tapered toward one end thereof and having one of its surfaces provided with transversely disposed teeth of equi-distant spacing while its other, and outer surface is flat, the other member being provided with an outer fiat surface and an inner surface which tapers from an intermediate point toward both ends of said member, with the apex or crown of said inner surface being adapted to fit intermediate of adjacent teeth of the first mentioned member.

2. Means of the class described comprising a pair of members, the one member being of right angular wedge-shape, having an outer fiat longitudinal surface and an inner or sloping surface provided with a series of transversely disposed grooves spaced at equidistances apart, while the other member is provided with a transversely disposed rib or ridge at a point intermediate of its ends, which is adapted to extend into vthe preselected groove of the first member.
