Patented July 16, 1929.
WILLIAM MACDONALD, OF DENNISON, OHIO.
DN'KING ATTACHMENT FOR COLOR PRINTING.
Application filed May 11, 1928.
This invention relates to a device or inking attachment for color printing and has for its object to provide, in a manner as hereinafter set forth, a device of the class referred to for enhancing the appearance of impressions obtained from electro-types, zinc etchings, half tones, engraved plates, cuts, etc., by giving color thereto.
A further object of the invention is to provide, in a manner as hereinafter set forth a device of the class referred to for giving color to black and white impressions obtained from electro-types, zinc etchings, half tones, engraved plates, cuts, etc, where by the impressions will be made unusually attractive, as well as distinctive to readily direct attention thereto.
Further objects of the invention are to provide, in a manner as hereinafter set forth, a device for the purpose referred to which is simple in its construction, compact, durable, thoroughly eflicient in its use, inexpensive to set up, automatic in its action, and obtaining the result desired in a thoroughly satisfactory manner.
With the foregoing and other objects in view the device consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the in-; vention, but it ,is to be understood that changes, variations and modificationscan be had which fall within the scope of the claims hereunto appended.
In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a top plan view of an apparatus for color printing in accordance with this invention.
Figure 2 is a cross sectional 'viewthereof illustrating the arrangement of-the device when employing a thick color ink.
Figure 3 is a fragmentary view in plan.
Figure 4 is a fragmentary view in section.
Figure 5 is a fragmentary view in section illustrating the device when employing a thin color ink.
Referring to the drawings in detail 1 denotes an open top container providing a lower reservoir 2 for the ink 3. The side and end walls of the container 1 and which are indicated at 4, 5 respectively are of greater thickness than the thickness of the bottom 6 thereof. The side andend walls 4, 5 are Serial No. 276,982.
provided with spaced, vertically disposed openings 7 having threaded walls and which extend from the top to the bottom of the container, and are open at each end.
A lid 10 is provided for closing the open top of container 1 and which is formed of an upper section 8 and a lower section 9. The lid generally conforms in contour to the shape of the body of the container 1. Preferably the body of the container 1 is of polygonal contour and the lid 10 has its edges flush with the outer faces of said body.
with an opening 14 having the wall thereof plane. The section 9 is formed with an opening 15 arranged below and of greater diam-' eter than the opening 13. The section 9 is also provided with an opening 16 which is arranged below and of greater diameter than the opening 14. The section 8 is formed with an enlarged circular opening 16 closed at its bottom by section 9 and which in connection with the opening 16 provides an upper reservoir 17. The section 9 has secured thereto a depending intake pipe 18'for the reservoir 17 The pipe 18 opens into the reservoir 2.
In Figure 2 the reservoirs 2 and 17 are shown as containing a thick color ink 27 and in Figure 5 reservoir 2 is shown as containing a thin color ink 17 and reservoir '17 empty. When thick color ink 2' is .used reservoir 17 is filled completely therewith and reservoir 2 partly filled. Reservoir 17 is not used for thin color ink 17" and when the latter is used reservoir 2 is only partly filled therewith.
Fixed to the section 9 and extending up of the screws extend through the openings 12 and 23 and havethreaded engagement with the walls of the openings 7, but do not threadedly engage with the sections 8, 9 and plate 19 whereby the lid 10 and plate 19 are slidable relative to the coupling screws 25.
On the application of pressure to the lid 10, the plate 19 will be compressed whereby the lid 10 will slide downwardly and the coupling screws 25 will remainin down position until pressure thereon is released, whereupon the plate 19 will act to restore the lid 10 to the position shown in Figure 2. WVhen the lid 10 shifts on the coupling screws the pipes 18, 18' will be carried therewith. The depression of lid 10 carrying plate 19 and pipes 18, 18 provides for the discharge of thick color ink from reservoir 2 to reservoir 17 and from the latter for color applying to the im- 7 pression, or for the discharge of thin color ink from reservoir 2 for color applying to the impression, and how such applications are had will be presently referred to.
The pipe 18 is employed for supplying thick ink from the reservoir 2 to the reservoir 17 and when thick ink is employed the pipe 18 is plugged as at 18". When thin ink is employed the pipe 18 is plugged as at 18 so that communication is closed between reservoirs 2 and 17 The discharge of the thin ink from reservoir 2 is had through pipe 18, the latter having its plug removed when the apparatus is used in connect-ion with thin ink.
Secured to the wall of the opening 13 and extending through the openings 15 and 20, as well as normally depending below the plate 19, is a peripherally threaded sleeve 26 providing an air intake for the reservoir 2. Operating in the sleeve 26 is a valve stem 27, provided with a valve 28 below sleeve 26. That portion of the stem 27 below valve 28 has mounted thereon a coiled spring 29. In Figure 2 the valve 28 is shown at its uppermost position due to the action of the spring 29 and such position is below the inner end of the sleeve 26. When the lid 10 is depressed the sleeve 26 engages the valve 28 and cuts off the supply of air to the reservoir 2and on the compression of the lid 10 the ink within the reservoir 2 is either forced into reservoir 17 and discharged therefrom or out through pipe 18 and discharged. When the lid 10 14 and depending through the openings 16,.
21 is an interiorly threaded annular sleeve 30, provided with an inset lower portion 31 and which provides a filling tube for the reservoir 2. The sleeve 30 is normally closed by a peripherally threaded plug 32 which has its inward movement arrested by the inset portion 51.
Secured to the section 8 of the lid 10 and extending across the opening 16 isthe cut or impression element .33 from which the impression is made. The cut is formed with openings or ports 34 for the passage of ink from reservoir 17 to the upper face of the out.
for applying color thereto. Cut 33 is also formed with an opening 35 for the upper end of pipe 18 and when the latteris employed for the discharge of ink from reservoir 2 the color will be applied to the upper face of the cut. To prevent leakage a packing means 36 is interposed between cut 33 and the upper face of section 8 of lid 10, but said packing means does not extend acrossthe top of reservoir 17. The cut 33 may be formed with lines 37 or designs 38, in addition to the original design of the cut and which can be printed in color. The lid 10 provides a re; siliently controlled carrier for the impression element. p i
The feeding or supplying ink to the upper face of the impression element is had automatically when the impression cylinder or plate of the press respectively passes over or bears against the impression element. The openings or ports 34 can be arranged in any suitable manner and of any size. The 'diameter of the pipe 18 can be as desired. lVhen thin color ink is employed it completely floods the upperface of the cut, but the thick color ink does not, as it spots the impression at spaced points. It is though that the many advantages of a device or inking attachment for the purpose referred to and in accordance with this invention can be readily understood, and although the preferred embodiment of the in vention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which fall within the scope of the invention as claimed.
