INK-FOUNTAIN.

f eZL' ILD'ZLOWL it may concern:

Be it liIiOWIZ that l, (Lassen R. TAYLOR, a zen of the Lnlte' tetes, residing at Specification of Letters Patent. I

Application filed April 1611907 Serial Ho. 368.4l65.

mington, in the District of 'Columl)ia,

have invented certain new and useful Imj lollow O is a specification.

filly invention relates to novel 1mprovemovements in ink-Fountains, of which the 5 sheet metal.

merits in ink fountains for orinti resses 1 l c 1 font and to arrange adjacent thereto a knife or doctor for limiting the amount of ink delivered by said roller. This doctor is adjusted by means of set screws, end, whenit is desirable to clean out the font, for any reason, l'or refilling withs dillerent ink, it has heretofore been necessary (-ll the set screws, and thus destroy the adjustment of the doctor.

The primary object of my invention is to provide means for cleaning the font and roller without destroying the adjustment of the doctor.

l 'i it-h the shove and other objects in view, my invention. consists in the construction hereinafter described, and illustrated in the accompanying drawings, in whiche- Figure 1 :1 plan vie w of my improved ink font. i2 is an end elevation of the some. Fig. is a transverse. section of the rly to fountains designed 3 in which the 111k 1s d1s- I Patented Jan. 28, 1908.

" End pieces 5, of sheet metal, are riveted or otherwise secured to the doctor frame, and

form therewitha kind of trough or box for the reception of the ink.

7 indicates the doctor, which, as shown in Fig. 3 consists of a thin, resilient plate of This lies over the upper surface of the doctor frame, and, at its rear edge, is secured thereto by means of rivets, 6. This construction leaves the forward edge of the doctor free, and, as shown clearly m Fig. 3, this forward edge projects slightly beyond the doctor frame.

A. series of set screws, 10, work in a rib 11, on the doctor frame, and their upper ends beer against the under side of the doctor, near its front ed e. The shanks of said set screws project oownwardl through elongated slots, 12, formed int e mainframe 1, the pu ose of which will hereinafter appear.

The esrings in the frame 1, for supporting the journals of the roller 2, and doctor frame 4, are semi-cylindrical, and caps, 8,

also formed with semi-cylindrical bearings it down over said journals and are secured in position by means of screws 9. Thlsconstruction is preferred, as it admits of thereedy removal of roller and doctor frame when desired.

Into one of the journals 13, of the doctor frame, fits it screw plug, 14, on which is rigidly mounted e worm-wheel 15/ A Worm same, taken on the line 33 or Fig. 1 and looking in the direction of the arrow. 4-

sn inverted plan View of the doctor frame. Fig. is aplen view corresponding to Fig. 1, but with the roller and doctor removed, and Fig. 6 is a diagrammatic view showing fragments of roller and doctor, and the manner of adjusting the latter.

Referring to the drawings in detail, my improved l'ont comprises e main frame or casting 1, in winch is journaled the inking roller To one end of the shaft, 3, of this roller, may be secured suitable driving means, (not shown). Also mounted in the casting 1, and supported by means of journals, 13, is a fountain bed, or doctor frame 4, a bottom view of which is seen in Fig. 4. From an inspection of Fig. 3 it will be seen that this doctor frame is thick, and practically rigid, being preferably formed of cast metal.

Fig.

end of the worm shaft, end ellords means 16, is arranged to gear therewith, end is j ournsled at its ends in brackets, 17,, 18, carriedby the frame 1.

A thumb nut, 19, is mounted on the upper by which the some may be turned. The operation of the device is as follows: In printing on job resses and the like it is free uently desireb e to supply ink more free y to one pert ofthe form than to en other, owing to the fact that parts of the type may be heavier than others. The desired distribution or flow of ink is therefore obteined by adjusting the several set screws 10 so as to cause them to bring the edge of the doctor to the proper distance from' the roller. If they are all turned forward to the same extent, they will, obviously bring the edge of the doctors u roller, and the ink will ilow uniformly. By setting forward some of said screws more than others, however, the doc r will be disparallel with thetorted, and parts of its edge, (as at 7 Fig. 6)

will be at a greater distance from the roller than other parts, and the ink will, of course, flow more freely, over that part of the roller which is at a greater distance from the doctor. justnient of the doctor it is highly desirable to maintain that adjustment while printing the entire edition from any particular form, even though some part of the edition be rinted in a different color from other parts.

11 order, then to clean out the font, for the purpose of changing inks, or other reason, the entire doctor frame is swung away from the roller by operating the worm 16. The doctor frame swings onits trunnions 13, and

the screws '10 move in the elongated slots, 12.

When cleaned, the doctor frame may be swung back, and printing resumed, the relative or local adjustment of the doctor, having remained undisturbed, and the distribution of ink being, therefore exactly the same as before. i

What I claim is I '1. In an ink fountain, a frame, a roller ournaled therein, a doctor in operative relation with said roller, means for adjusting said doctor locally at any point throughout its length, and means for bodily moving said doctor without interfering with such local adjustment.

2. In an ink fountain, a frame, an ink roller journaled therein, a doctor frame also journaled therein, means for swinging said Having once obtained the proper ad doctor frame,a flexible doctor secured thereto, and in operative relation with said roller,

and local adjusting means for flexing said doctor, carried b said doctor. frame.

3. In an ink 'ountain, a frame, a roller i40 frame and bearing against said doctor, and r means for bodily swinging said doctor frame on its journals.

4. In an ink fountain, a main frame, rovided with slots, a roller journaled therein, a doctor frame also journaled therein, a doctor carried by said doctor frame in operative relation with said roller, adjusting screws carried by said doctorframe and bearing against said doctor at intervals throughout its length, said screws'having their shanks rojecting through the slots in said main rame, whereby ready access may behad to said screws, and means for swinging said doctor frame to and from said roller.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
