CANFIELD, OF LOS ANGELES, CALIFORIA PROCESS .AND APPARATUS FOB INKING EMBOSSED WORK Original No. 1,797,323, dated March 24, 1931, Serial No. 412,8091ed December 9, 1929. Application for reissue ined August 5, 1931. serial No. 555,334.

In this specification, and the accompany ing drawings, I shall describe and show a preferred form of my invention, and specifically mention certain of its more important `g; objects. I do not limit myself to the forms disclosed, since various changes and adaptations may be made therein without departing from the essence of my invention as hereinafter claimed; and objects and advantages, other than those specifically mentioned, are

included within its scope.

My invention relates to means for inking embossed surfaces; such as raised letters, designs, and borders. Among its principal objects are: first, to provide an improved means for inking such surfaces to secure sharply l defined outlines, and to eliminate fringing effects; second, to effect a material saving of ink required for this purpose; third, to make it possible to ink raised borders, etc., that enclose other raised work; fourth, to afford facilities for inking di'erent portions of raised work in different colors, at one operation; and, fifth, to provide simple and practical apparatus for accomplishing the above results.

My objects are attained in the manner shown in the accompanying drawings, in which Figure 1 illustrates simple form of handapparatus for utilizing my invention, the view being in lan, and having certain parts broken away or convenience in disclosing the underlylng structures;

Figure 2 is a side elevation of the above apparatus, with certain parts broken; and,

Figure 3 is an end elevation of the apparatus, in section taken on the line 3-3 of lSI5 imilar reference numerals refer to similar arts throughout the several views.

or the purposes of this disclosure, I have selected as an illustration of the app-lication of'my improved process, a method of inking certain raised surfaces on a book cover 5. Thus the words Calif and process comrise embossed letters 6 and 7 respectively. il`he word Process is enclosed within a border 8 which is also embossed. It will be noted that the letters composing the word Calif are placed upon the book cover diagonally; andA we will assume that they are to be co1- ored yellowl and that the letters composing the word rocess, and the border therearound, are to be colored red.

The simple form of apparatus shown for accomplishing the above purpose comprises a bed-plate 9, having parallel longitudinal V-grooves 10 near the respective edges thereof, and a longitudinal rack 11 at one side. At the right-hand end of the machine is an elevated ink-fountain 12, adapted for being variably divided by removable partitions 13. This fountain has a slot 14 at the bottom, eX- tending from one end to the other, and directly below the slot is a rotatable distributing roller 15. This is mounted in bearings 16 on the frame of the fountain, and is adapted for being driven at a uniform rate of revolution, as by the pulley 17.

A vcarriage 18, of inverted U-shape, having wedge shaped feet 19 engaging grooves 10, is longitudinally slidable upon the bedplate. The opposed legs of this carriage are horizontally slotted, as shown at 20, in such a, manner as to provide guide-ways for horizontally slidable blocks 21, of which there is one at each side. These blocks are provided with outstanding lugs 22 carrying adjustably positioned eye-bolts 23. Tension springs 24 are stretched between these eye-bolts, and studs 25 on the carriage. By means of these springs, the blocks 21 are normally constrained to remain at the left-hand ends of slots 20.

Between blocks 21, and carried thereby in bearings 26, is a freely rotatable application roller 27. A somewhat larger inking roller 28 is rotatably mounted directly between the legs of the carriage in bearings 29. The shaft of the latter roller carries a spur gear 30, which engages rack 11 and thereby rotates this roller as the carriage is pushed back and forth in the V-grooves of the base.

Operating handles 31 extend outwardly from blocks 21, and by their means carriage 18 may be slid upon the bed-plate from one end to the other. Thejmotion of the carriage to the right-is limited by its feet 19 coming inY contact-,with feet 32 of the ink the -embossedtfwork tov besinl fountain. When this occurs, although the carriage can be pushed no further to the right, the blocks 21 can be moved further in this direction, by slightly stretching the tension springs 24. This allows application roller 21m contact with distributing roller 15, and to obtain u supply of ink on its surface thereby. Y l

Assuming that the raised work to be inked is embossed on or other yieldable material, it is usually best to lace it upon au underlying die-plate 33. 'nking 'pa'd's 34, of relatively thick sheet rubber, are out to shapes indicated by dotted lines 3'5, te include the raised lettering or other raised work that vis to lbe inked `ifn Vany one color. These inking `pads are then cemented to inking Vroller 28, in proper positions to register with the work that is to be inked. Adjusting screws 36 (shown only `in Ffiig. 2) are provided at 'each side Aof the curia e, to limit the 'letehaad movemelt of biloc 21 and thus provide any ldesired pressure vof 'contact between application roller 27 and the inking pads '84.`

'Assuming that yellow .printing ink 37 is deposited in section 38 of the ink 'founta'in, and that red ink 39 Vis 'deposited in section 40 ofbethe yisaauiglu that distrilutiln rollgexl` 15 is ing'rot ypower a ie t :rou pulley 17, the dperatiol'n is asligllows The operstrgrasps handles 31 and pushes them toward the right vso as to move application roller 27 against-distrilmting roller 15. The a plication roller wiilithus Vhave 'imparted to 1t circumferential "bands vof yellow and red ink. Assoon zus-the right-hand pressure uponfthe handles is y"released,springs V24 will retract the `application roller to 1theleft, and cause it to-'contact with inking pads 34. The carringe'is then moved to 'the left yby means ofthe handles,a'nd theengagement between spurJgeer 30 and rack f11 will cause inking roller 28 to revolve. Thefinks Von the applicationfreller 'will thus be :spread upon the inking pads 34, and the latter 'will deposit the vink in its `respective 'colors upon d, as soon as Ythecurrimge 's'nioved-suently fur towards the left.

From the foregoing description itiwill be apparent' that 'embossed work of a great vs rietyfofdesign fmay b inked =by vmy innproc'ss, in a number 'olf coloni abone operation. 1t *willf'dlso'be'seen that no stencils are r uited in the process. Still further it 'wil 'appear' "that enclosing Ycontinuous r rs fbe used, which yis not poible A*when stencils hre employed. 'The Alinkirig pads 34 may be made of any desired thiol-QV ness, which is a very great advantage when the body of the work to be inked is rough, wrinkled, or buckled. Finally it will appear that there will be a material saving of ink by reason of the fact that the ink is applied only to nking pads 34, and not to the entire surface of the inking roller.

Althou h, for the sake of simplicity, I have 'shown 'a described a very simple form of hand-apparatus for making use of my improved process, 1t will be apparent that the Work may be accomplished by` automatic machineryadapted to 4function in the same manner. Such machinery can readily be produced .by competent designers, in the light of this disclosure.
