DUPLEX INKING ROLLER 4 Filed Feb. 10, 192'? gmntoz %MMM Patented Oct. 15, 1929 NIT D 51' AT it'lE rarest or DUPLEX INKING ROLLER Application filed February 10, 1927. Serial No. 167,250.
This invention relates to ink-supplying means for use in connection with machines of the type known as Burroughs adding machines or multigraph printing presses or the like, and more particularly to rotary ink containers or inking rollers especially designed for applying ink to the type or printing means used in machines of the character referred to. p i
The primary object of the invention is to provide a sectional or duplex ink supplying roller with associated means for applying ink to the type or printing devices of machines of the character referred to, whereby a constant supply of ink is maintained and evenly distributed over the surface of the type or printing means.
A further object is to provide a fluid. inking reservoir consisting of hollow or tubular inner and outer telescopically connected members each having minute orifices therein and provided with simple and efiicient means for adjusting and holding the two members in relatively stationary position with the orifices in one member in registering position with the orifices in the other member, or in non-registering position, and to vary at will the quantity of ink supplied to the printing devices.
The invention will first be hereinafter more particularly described, with reference to the accompanying drawings, which are to be taken as a part of this specification, and then pointed out in the claims at the end of the description.
In said drawings, Fig. 1 represents a longitudinal side elevation of one roller or section and a sectional view of the other roller or section of a duplex fluid inking reservoir or inking roller embodying my invention;
Fig. 2 is a transverse section taken on the line 22 of Fig. 1; and
Fig. 3 is a plan view showing triple rollers or roller sections.
My improved duplex or sectional inking roller is adapted to'be applied to machines of known construction, by means such as are ordinarily employed for, attaching ink supplying rollers to such machines; the inven tion being designed for general application to machines of different types, in which printing devices are used, and it is thought to be unnecessary to illustrate or describe any particular type of machine with which the ink supplying roller may be used, or the means employed for attaching the same thereto.
Referring to said drawings, in which the same reference letters are used to denote corresponding part s -in different views, I have shown, in Fig. 1, two fluid inking reservoirs or ink supplying rollers A, A, revolubly mounted in suitable bearings provided therefor on a supporting frame B, and inasmuch as these two rollers are substantially identical in construction, a description of one will suiiice as a description of both.
Each roller consists of an innermember a and an outer member a preferably of tubular form, each having minute orifices therein arranged normally in registering position with the orifices in the other member, or vice 'versa; one member being movable upon or within the other member so as to cause the orifices therein to register with the orifices in the other member, or not, as desired.
The outer end of the inner member has secured thereto or formed integrally therewith a tubular axial extension a which is exteriorly threaded and protrudes through a circular opening in a side portion of the frame B, and has formed thereon or secured thereto, at its inner end, a radial projection or flange a to which is secured, by means of a pin a or other fastening means, an, end portionof a cylindrical body I of felt or other absorbent material surrounding the outer member of the ink container.
Preferably said body consists of a series of rings i of suitable material secured together so as in effect to form a solid body by a bolt or bolts a passing through the series of rings and connecting circular end plates am having central openings therein fitted upon the outer member of the container. To insure the feed of the ink more freely or in greater measure thanif the central openings through the rings were of the same size and adapted to fit closely around the surface of the outer member of the container, the opening through each alternate ring 2', starting with the next to the outer ring of the series at either end is preferably larger than the openings through the adjacent rings on opposite sides thereof, so as to provide a slight clearance or annular space between the surface of the outer member of the container and the inner surface of the ring, in which space the fluid may flow around the container.
To the aforesaid side portion of the frame B is secured, by set screws or the like, a ring C having on its inner edge an annular flange 0, so as to provide between it and the adj acent frame bar an annular recess in which is revolubly fitted an annular radial flange on the inner end of an adjusting device D, preferably in the form of a thumb nut screwed on said axial extension a and adapted to be turned in either forward or backward direction for the purpose of moving the inner member of the container in the direction of its axis so as to cause the orifices therein to register with the orifices in the other member, or vice versa, according to the direction in which the nut is turned.
The outer end or head portion of the nut has a milled surface to facilitate turning it and spaced indentations therein with which a tooth on the free end of a resilientpawl or dog 6 may engage to prevent the nut from turning, except by applied force; said pawl being carried by a ring or washer E, which is fitted loosely on the axial extension (4 and adapted to be non-rotatively confined thereon between a lock nut F screwed on said ex tension and a nut or interiorly threaded end portion of an open-ended tubular member Gr also screwed on said extension and forming an auxiliary fluid container having a filling aperture therein co-incident with a hollow boss on which is screwed a cap 9 for closing said aperture.
The said adjusting nut for opening and closing the orifices in the container. as shown at the right hand side of Fig. 1, is in open position with the toothed end of the pawl e engaging an indentation in its periphery so as to hold the two members of the container with the orifices therein in registering position, while the adjusting nut at the left hand side of Fig. 1 is shown in the position it occupies when the pawl c engages an indentation in its periphery, so as to hold the two members of the container with the orifices therein in separated relation, or non-registering position, but by turning the adjusting nut with suflicicnt force to release the pawl from the detent, the inner member of the container will be moved in the direction of its axis sufficiently to bring the orifices therein into position to register with the orifices in the outer member, or vice versa, in which position the adjusting nut and the two members will be retained by the detent until the nut is again turned.
A spreading or distributing roller H is shown for applying ink to the type or printing devices, although in some instances it may be preferred to run the inking rollers directly over the type. This roller is revolubly mounted on the machine frame by means of rockable levers h in which it has its bearings and which are pivoted atan intermediate point to a flexed element of the machine frame, so as to adapt the roller to contact with the printing devices for applying ink thereto. Said roller H is held in yieldingcontact with the surface of the absorbent body I by means of a spring or springs K connecting the free end of one or both levers h with a fixed part of the machine frame.
Both inking rollers or both sections of the duplex roller may be rotated in unison, by means of a ratchet wheel L secured on the inner end of one of the rollers or roller sections and adapted toengage a pawl (not shown) pivotally attached to the operating mechanism of the machine, or if-desired, each roller may be rotated independently 10f the other by means of a ratchet wheel on the in her end of each roller actuated by separate pawls pivotally attached to said operating mechanism.
When this ink contalner or inking roller is used in connection with a machine such as ing a connection at one end with a key lever on the keyboard.
If desired to use three or more rollers or roller sections, a third roller'A without the axial extensions shown in Fig. 1, may be placed between rollers A A as shown in Fig. 3, and actuated by means of pawl and ratchet connections in the same manner as the duplex roller, the third roller being provided with a filling aperture at one end thereof, as shown, in which is secured a removable stopper In operation, when it is desired to adjust the movable member of the container so as to open or close the ports formed by the orifices in the two members when in registering position, the thumb nut is turned slightly so as to release the toothed end of the resilient pawl 0 carried by the adjacent nut from engagement with one of a series of depressions therein and cause the toothed end of the pawl to snap into engagement with another depression, thus separating the orifices in the two members of the container or bringing them together, more or less closely, to cause the device to feed faster or slower, as desired;
