Application filed August 2'7, 1903. Renewed April 5, 1904. Serial No. 201,7 16- T ($37 W/ (O/111W! on a reduced scale,ol" elements whichare shown Beitknown that l, FREDERICK \V. Humane, in Figs. 1 and 2. a citizen of the United rltates, residing in the .ltelerence characters are relatively alike borough of Brooklyn, in the county 01 Kings throughout the drawings. 5 and State of New York, have invented a new In the drawings, A designates an inkingand useful limiwovement in Oonstrictors for table, upon which m'inting-il'iks of ditiering linking-Rollers, of which the following is a colors or qualities may be distributed either 55 specification. evenly or in ditiering quantities by any suitltly present invention pertains to constrieable means. (Not shown.) For the purpose 1o tors which are designed to be applied circumof ilhistrating and describing my invention l erentially of the inking-rollers of printingthe surface of the inking-table A. should be presses and by reason of the combination thus considered as divided loi'igitudinally into a 60 el'lected to obtain a diversity ol, inking etlects plurality ol inking-'laces, herein shown as two from a suitablyprepared inking-table by in number namely, A and rv which may 15 means of the operation of each roller thus be mulerstood to lie on either side oi an imequipped. aginary line A, which lies on the same ver- Among the objects which I obtain by my intical plane asthe middleo'l aconstrictor, which 5 vention arethc following, namely: the ada 'itais herein referred to as l and is mounted upon bility of an inking-roller for use in combinai an inking-roller 2. lhe inking-roller 2 may tion with a variety of inks or with various be of any required dimensionsand madeof any quantities of one kind ol ink, in combination suitable material. The constrictor 1 may be either with a plurality of parts of the surface made of any suitable flexible material which 7 of one printing-form or with the entire snrhas sul'licient tensile strength for the purpose face of each of a plurality of printing-forms, of my invention. .l. prefer, however, to make and also the adaptability of a roller to be used the constrictor of relatively thin and some in combinatioi'i with a form in which is lixed what resilient metaL-such, for instance, as one or more perlol'ating-rules or other prosteel. A strip of such material of suitable 75 truding elements which need not or should not length and breadth for its intended use is re be inked and which if they contact an unproduced in width somewhatat one end part thereteeted surface of an inking-roller cutor otherof, as at 1", and this narrower end part is then wise mar or damage the latter. 'fm'med into a hook by bending itdown toward in the drawings, Figure 1 is an elevation, and nearly upon the body 1 of the device, 0 as from the forward end of a printing-press, leaving, in tact, su'llicient space between the of a part of an inking-table and of a part of end part of hook 1 and the body 1 to receive an inking-roller with a constrictor mounted a thickness of the same material. Near the thereon. Fig. 2 is an elevation of the inkingopposite end of the body 1 a plurality of slots roller and two constrictors and oi a part of 1 may be formed in and transversely of the 85 each of two forms of type, one of which conlatter, each of said slots 1 being of suitable tains a perforating-rille. Fig. 3 is an clevadimensions to permit the bent-end part or 40 tion of a part oi an inking-roller, part of book 1to behooked therein. Anyothersuitwhich is constricted by means of a constrictor able means may be used for so connecting the which is mounted thereon, parts of the conend parts of the constrictor 1 as to secure it 9 stricter being shown in vertical longitudinal upon and to cause it to constrict the roller 2; section. Fig. at is an elevation of a constricbut I prefer the means herein illustrated and tor. Fig. 5 is a transverse vertical section of described.

a constrictor through the line a a, Fig. et. Means are provided for preventing the pe Figs. 6 and 7 are elevations of modilied forms ripheral edges oi the constrictor 1 from out of a constrictor; and Fig. 8 is a top plan view, ting and rflamaging the Face of the roller 2.

These maybe of various forms or construction according to their respectively-designed uses. I prefer, however, to attain the desired end by curving outwardly the edge parts of the device, thus giving to each of said edge parts the form which is hereinafter termed and referred to as a protective edge 3. In some instances it may be necessary to provide means for retaining the constricted part of the roller 2 at a slight distance from the surface of the inking-table A, this being sometimes rendered more necessary by reason of a slight increase which maybe caused diaine trallyof the roller by the constriction thereof by and contiguous to the constrictor 1. For the purpose mentioned I prefer to form certain elements which are hereinafter designated and referred to as riding ridges, and these may be made by recurving, as at a, the edge parts of the protective edges 3. It will be noted that the riding ridges if formed of suitable material-such, for instance, as spring metal will have a resilient bearing upon the inking-table A. This resiliency, however, as will be hereinafter more fully related, will be of more marked advantage where a constricted inking-roller contacts one or more typeformssuch, for instance, as are illustrated and referred to herein as forms B and U. The riding ridges at may, however, comprise elastic and resilient bands, which may encircle the constrictor, as shown in Fig. 7; but I prefer those which are integral with the constrictor, as before described.

here relatively narrow constrictors are used-as, for instance, where they may be required to prevent the roller 2 from contacting a perforating-rule--such, for instance, as the one which is shown in Figs. 2 and 8, respectively, and referred to herein as (/acircuinferentially-grooved band of suitable material may be used for the purpose, means being provided to cause it to encircle the whole circumference of the roller. Such a constrictor is shown in Figs. 2 and 8, respectively, and is referred to herein as 1. This I prefer to make of metal which shall have sul'licient resilience to cause it to constrict the roller 2 at least slightly, and thus maintain itself in its normal position relatively of the roller. Means are provided to facilitate the positioning of the constrictor 1 on a roller .2. In the form shown in the drawings the constrictor 1 is divided, as shown by the line 1", which by reference to Fig. 6 will be seen to enter one side of the constrictor 1, divide the latter for a certain distance on a plane transversely of its axis and at one side of the center of the constrictor, and pass thence outwardly at the side opposite to that at which it entered, the constrictor thus formed being provided with parallel contact-faces, which when the constrictor is in position contact each other circumferentially of the roller 2.

The operation of my invention may be described as follows: here different inking effects are required for one or more type-forms, which are mounted on the bed D of a printing-press, the parts of the surface of the inking-table which are in longitudinal alinement with the parts of the type-forms upon which said different inking effects are to be produced should be respectively properly prepared with the inks which will be required for the purpose mentioned. The inking-rollers of the press should then be respectively provided with coustrictors 1, which should be respectively positioned on the several rollers so that they severally extend, at least approximately, an equal distance each side of the adjacent margins of the difierentially-inked parts of the inking-table.

Any suitable means may be used to properly distribute the different inks upon the ink.- ing-table, and should distributing-rollers form the whole or a part of said means they may also be equipped with constrictors 1 in a like manner with the inking-rollers. Assuming, however, that inks of the various kinds required have been distributed upon the inkingtable A in the desired quantities, the inkingroller 2 will transfer said inks to the surfaces of the printing-forms B C if said surfaces and inking-roller be properly contacted one with the othcras, for instance, by the usual operation of a cylinder-press and it will be noted that the several divisions of the inkingroller 2 if properly defined and separated by constrictors 1, as before related, will respectively transfer unmixed and unblended ink from the several correlative divisions of the inking-table A to the prearranged correlative parts of the surfaces of the type-forms B C. If a perforating-rule (Z be inserted in a typeform and longitudinally of the bed D, a constrictor 1 should be placed on the inkingroller 2 in the relative position which is shown in the drawings.

In placing a constrictor on a roller it should be spread open circumferentially sufliciently far to enable it to pass readily longitudinally of the roller to its destined position, when it may be permitted to close upon the roller, and if, as shown and described herein, it be provided with engaging means for securing an outer end thereof to the body thereof said means may then be engaged, and if said means are adjustable they should be so adjusted as to cause the device to slightly constrict the roller. hen positioned and secured as thus related, the protective edges 3 prevent the edges of the constrictor from cutting or otherwise injuring the roller, and the riding ridges emay ride upon the inking-table A and upon the surfaces of the type-forms, thus preventing the body of the constrictor from contacting either the inking-table A or the type-forms, and the resilience of the riding ridges 4: will so cushion the latter as to prevent them from injuring any faces which they may contact in teases the type-jlbrn'is. The grooved constrictor l prevents the perlorating-rule (J from being int'ed by the roller 52 and also prevents the latter from being injured by the perforatingrule (1, and because of its grooved form it comprises within itsell all the functioi'is of the wider constrictor, including those of the protective edges 3 and of riding ridges 4-. The principal function of a wider constrictor consists in providing an uninked, and therefore functionally inoperative surface For an inkroller, thus in fact, iorming an inoperative zone about the latter and positively preventing the intermixture and consequent blending thereon of the dill erent inks which may he used on the type-trams.

lVhere the riding ridges st are separable from the body of the constrictor, as shown in l ig. 7, one or more of the former may he used, according to the special requirements ol the latter. l Vhen separable riding ridges are used, they may be placed in position by expandii'ig them sulliciently to permit them to encircle and to be contacted upon a previouslyplaced constrictor, thus not only serving as riding ridges, but also by their resilient contraction causing the constrictor to constrict theii'llcing-rollerfl. A sin arable riding ridge may consist of a continuous annulus, or it may be divided transversely similarly to the constricter 1.
