Application filed October 9, 1915. Serial No. 54,928.

To all whom it may concern:

'Be'it known that I, BRUCE 0. WHITE, a

a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Cleaning Devices for Printing-Machine Inking Mechanism,

"fully described and represented in the following specification and the accompanying drawings, forming apart of the same.

This invention relates to certain improvements in inking mechanism for printing machines, andparticularly to that type of inking mechanism in which the ink is dis tribut'ed by means of a plurality of nozzles, a nozzle being provided for each column or section ofth-e form, the ink being delivered to these nozzles under pressure, which may be produced by a series of pumps. In

this type of inking mechanism the ink is delivered by the nozzles through small orifices and it sometimes occurs that these or1- fices become choked or stopped up by ink,

up while the machine is operating. Be-

to produce a construction of simple form,

cause of this liability to stoppages, especially when the, mechanism is running, it is necessary for the attendant to examine the delivery orifices from time to time to see if the ink is being properly delivered,

or papers will be spoiled. When a stoppage occurs it is necessary to clean the orifice with a piece of wire or other tool. If several of the orifices become stopped up,

this method of cleaning requires time to perform, and this method of cleaningorifices is for this and other reasons unsatisfactory.

It is the object of the present invention by which in a machine employing. a plurality of ink delivery nozzles or orifices all the nozzles or orifices may be simultaneously cleared from time to time by the attendant,

' and construction of such characters that when the mechanism isnot being operated, the device may be used to close up the nozzles and thus keep the ink from drying in them and stopping them up.

For a full understanding of the invention a description will be given of the preferred form of an apparatus embodying the same in connection with the accompanying drawings, in which Figure 1 is a side elevation, partly in section, of so much of an inking mechanism of the type referred to as is necessary for a full understanding of the invention, and

Fig. 2 is an end View, partlybroken away, of the mechanism shown in Fig. 1, lookin toward the left in that figure, the distributing cylinder being omitted.

The inking mechanism with which the mechanism shown is especially designed for use is fully shown and described in my prior application Serial No. 38,528, and only so much as is necessary for a full understanding of the present invention is here shown, and this will be only briefly described.

Referring to the drawings, there are pro vided a plurality of supply conduits or pipes 1 to which ink is delivered under pressure from a reservoir provided with a plurality of pumps, one for each ink conduit, these pumps, the reservoir and con-.

nections to the conduits not being shown. These ink conduits or supply pipes have their delivery ends arranged in line along a.

passages 6 before described, this bar also acting to divide these pass'ages from each other to column or other form section width.

The inclined surface 8 extends substantially into contact withjthe distributing cylinder 2 and theink from the orifices 7 spreads inflowing down the incline so as to form a 'contlnuous thin stream or layer of ink-in contact with the distributingcylinder. These small orifices 7,- as before stated, are liable to become stopped up or plugged up with ink, and in accordance'with the present invention means are provided whereby thesenozzles can be'- simultaneously cleared all alongthe cylinder from time to time the attendant, so that the necessity for examining them is done away with and a free and clear distribution of ink from all the nozzles is assured, and, in' the event of several of the nozzles becoming stopped up or plugged, they can all be cleared at once, and the time consumed iirseparately cleaning them is saved. VVhile' the particular construction for effecting this may be varied, in the preferredembodiment of the 1 invention there will be provided a plurality ofjcleaner or ejector pins 10, one pin being providedfor each orifice. 'These ejector pins are mounted in alinement with the orifices and operate seas ton-simultaneously move into the orifices; the pins being dimensioned to snugly fit the orifices and effectually'remove from them any foreign material which may cause stoppage.

A convenient construction which may, however, bevar'ied in its details, for effecting the simultaneous movement 1 of the ejector'p'ins is'that shown in the drawings. As illustrated the-pins are carried on a bar 11 extending-across the distributing-mechanism, the pinspassing through holes in the nozzle piece or bar 9 before referred to. These holesin bar 9 are in alinement with the orifices and are of suflicient depth to act asaguide' for the pins when they are moved u, soTas to "insure their proper movement into the orifices, the nozzle piece 9 being provided with a depending portion 12 in which these" holes are formed. In the particularconstr uction" illustrated, the orifices 7 are arranged vertically and the pin-carrying 'barlll is'given a lifting movement to move th'e'pins in and out of the orifices. As

shown, this movement is effected by mounting the bar 11 in a pair of brackets 13, 11, secured to the casing 3, the bar being vertically movable in its brackets. Also mounted in these brackets and extending across the machine is a shaft 15 which has collars 16, 17 fast thereon, these collars being provided with extensions or lugs 18 taking into slots in the bar 11. The shaft is rotated and the bar 11 lifted by means of a suitable handle 19. If desired, springs 20, taking between the brackets and the collars may be employed for cushioning the upward movement of the ejector pins and assisting to some extent in the return thereof.

With this construction, allthe nozzles can be cleared of ink simultaneously by the attendant bysimply' manipiilating the handle, and this can be'done so frequently as to obviate the necessity for examining-the nozzles. This construction is ail-especially convenient 'onefor the upper decks of ma chines where there are two or more decks of inking mechanism, in that the ejector bar operating handle I may be located on the floor and the ejector bars of each deck connected by rods, so that all can be operated simultaneously. Furthermore, the nozzles can be completely sealed by the ejector'pins whenthe machine is not being operated.

While the invention has been shown in connection with a plurality of nozzles having small ink delivery. openings, it will be understood that the invention is capable of use with other forms of nozzles and is not tobe restricted to the particular form shown and described.

, What is claimed is: I

1. In an inking mechanism for printing machines,the combination with a plurality of unobstructed inkrlelivery nozzles, of an ink distributing surface to which the nozzles deliver, a plurality of separate cleaning devices, and means for operating-the cleaning devices simultaneously for clearing the nozzles. V

2. In an inking mechanism for printing machines, themombination with a plurality of unobstructed ink delivery nozzles, of an. ink distributing surface to which the nozzles deliver, a plurality of ejector pins, and means for moving the-pins into the nozzles.
