.application filed November 23, 1912. Serial No. 733,082.

To all whom fit may concern Be it known that 1, .learns il Dorian, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Uhio, have invented a new and useful Improvement in Appliances for Distributing; a Fluid, of which the following is a specification, the principle of the invention being herein explained and the best mode in which 1 have contemplated applying that principle, so to distinguish it from other inventions.

The above entitlinggr of my invention is broad in its scope. A specific association of the conception is with the printing art; while still more particular reference may be had, for the exemplifying purpose in hand. to the relative control mechanism of the several transferring rollers commonly used in conjunction with an ink distributing disk.

@ne object of my invention is to provide a mode for substantially completing the measure of increased eliiciency, so that the distribution of the ink over the type will be still more uniformly accomplished prior to each impression therefrom.

Another object is the provision of mechanism which will be simple, economical of manufacture, readily attached or substituted and satisfactorily adjustable as the requirement may be.

rlhe inventive conception is embodied in means which are hereinafter explained and variously combined in the claims, while the annexed drawing and particular description thereof together set forth in detail one certain means constituting?,f my invention7 the disclosed means however being but one of various mechanical forms in which the principle of my invention may be applied.

Referring now to the drawing in which like characters of reference consistently designate like parts in the several figures: Figure l is a side elevation of an appliance embodying,1 my invention, mounted upon an upper part of the printing press and showing` the immediate actuating member of the latter partially broken away. Fig. 11 is a top plan of the contrivance proper, Fig. 111 is a section on line lll-dll of Fig. lt looking` in the direction of the arrows.

lThe main construction of the printing press as such, includes a base frame, actuating contrivances and essential inter-connecting details5 all assumed to be disposed in a feasible manner and hence as neither necessary to be shown in the drawing, nor requiring specific description here. Accordingly, only that actuating member of the en tire press which does directly articulate with7 and propel the relative movement of, my inventive elements will be hereinafter considered. The upper portion of the frame constitutes the support for the usual pair of obtuse angled tracks 1 in vogue in presses embodying1 this specilic kind of action. rlhese tracks accordingly have apexes 2 inciw dent-al to their angular formation. Positioned between the upper portions of the tracks in any suitable manner is an ink distributingg, disk 3 and similarly disposed in some approved fashion between the lower disposed portions of the track is a type-form 4. Located laterally adjacent one of the tracks and conforming substantially thereto in contour so as to lie within substantially the same planes, is an angular rack 5 indicated as secured through the medium of screws G. llt is upon these tracks that the roller carriage or saddle 7 is designed to travel up and down with a reciprocal movement. Such motion, as has been earlier stated, will be assumed to be directly imparted throlxgh the medium ol two saddle rods 8 partially seen in Figs. l and lill. Each of these rods articulatcs with the saddle through the medium of pins 9. llnteriorly positioned upon one of these pins and specilically upon that one which is disposed on the same side with the rae r 5 and moreover in the same vertical plane, is a driving gear 10 adapted to mesh with and reciprocate along the rack as will be readily understood. 1t is by the employment of power communicated through and actuating the rods 8, that the reciprocal travel of the saddle Z c'liected.

The opposite lateral ends oil' the saddle when upon the track comprise respect .feiy an upwardly and a downwardly projecting bracket 11 and 12. Depending from opposite ends of these brackets are the members 13 and 111 respectively, adapted to serve bushingI supports for the roller shafts 155 and 1G respectively. Each of these shafts has mounted on opposite ends subsidiary rollers 17 and 18 and it is these which are adapted to traverse the tracks 1 as clearly indicated in Fig. lll. Mounted upon the shafts 15 and 16 and intermediately of the rollers 17 and 18 respectively, are the two cylindrical inking rollers 19 and 20. These hence t UCI are preferably of a yielding composition of matter well known to the art. As so disposed and spaced, these inking rollers are intended to rotate successively across and in contact with the ink distributing disk 3 and type-form et. rEhe upper inking roller 19 is fixed to the shaft 15. The lower inking roller 20 is somewhat shorter thanthe roller 19 and is loosely mounted upon its shaft 16 for a purpose which will hereinafter clearly appear. The adjustment of the rollers 19 and 20 relatively to each other is accomplished in the usual manner through the medium of openings 21 and 22 and fastening screws 23 and 24 respectively.

Centrally :mounted upon the saddle 7 through the medium of two complementary and removable bushing forming members 25 is a third roller shaft 26. The position of the shaft 26 is moreover somewhat higher with respect to the shafts 15 and 16. rThis shaft is in fact a spline shaft as indicated at 27 in each of Figs. Il and IH and for a purpose acknowledged as old in this particular art. The removal of the complementary bushing members 25 located on opposite sides of the saddle is accomplished through the medium of the cross-slides 28 and thumb screws 29. Positioned upon the shaft 26 just inside one of the members 25 and so as to also lie in the same vertical plane as the rack 5 is a driving pinion 30. The positioning of this pinion is moreover such that it will lie in mesh with the driving gear 10. Mounted in the customary manner about the spline 27 so as to become in conjunction with another part to be described, both rotatable about and slidable upon it, is a slightly smaller ink-distributing roller or vibrator 31. This member is generally composed of metal and its interpositioning with respect to the rollers 19 and 2O is such that it has a substantially uniform lineal contact of suliicient pressure with each. The opposite end of the vibrator 31 is supported through the agency of the now well known screw threaded shaft 32 adapted to fit complementary screw Vthreads in the member 25 employed on that particular end of the saddle; and incloses within its own opposite end the spline shaft 27 as sufficiently indicated, since not novel, in Fig. lll.

The operation of my appliance should now be recognized to be as follows: Assuming the saddle to be in its uppermost position upon the ink distributing disk o; the vibrator 31 therefore, as suggested by the direction-of-movement arrows in Figs. I and ll, the maximum distance removed from the pinion 30; and the loosely mounted inking roller 20 abutting the subsidiary roller 18; it will be noticed first that he vibrator 31 is capable of sliding axially a greater distance than the inking roller 20. rlhe relaa different ratio as regards extent. As the" saddle proceeds downwardly the friction exerted by the vibrator 31 upon the inking rollers 19 and 20 suffices to Vcarry the lower roller 2O along with it in an axial direction.

Inasmuch now as the vibrator 31 is intended' to slide through its maximum extent during the time which it takes the saddle to travel from the top of the ink distributing disk 3 to the bottom of the type-form 4, and the extent of axial movement of the lower or" inking roller 2O has been presumed, while taking account of a variant friction between it and both surfaces (especially the typeform) over which it passes to be one-half; it is obvious that the roller 2O will abut the subsidiary roller 18 which it is approaching and hence come to a stop as regards its axial movement when the saddle is passing over the apex 2. Consequently, the inking roller 20 is compelled to pass over the typeform on its downward trip in the same manner that the upper inking roller V19 does. As contradistinguished, on its return trip, due to the sliding ofthe vibrator 31 in the reverse direction, the inking roller 2O will pass upwardly over the type-forni in a helical direction with respect to its own axis. It is the occasioning of such a different lino of travel of the inking roller 2G over the type-form which is calculated to edect an approximate consumation of uniform ink distribution. The lines of travel of the inking roller 2O over the ink distributing disk 3 are similar save that the order of the different routes of travel is reversed. ln the meantime, the function of the vibrator 31 has been in no wise impaired, merely added to. It should be noted also as of practical advantage, that on gears or pinions are mounted upon the shafts of either of the rollers 19 or 20, hence the adjustment of these two rollers, made necessary by gradual wear, is possible without bringing about a binding effect between such enmeshed gears or pinions.

Having now fully described my invention,
