INKING MECHANISM.

Application filed April 24,

'10 all whom it may concern Be known that I, Honour Hon, a citizen of the United. States, residing at Battle Creek, in the count y of Calhoun and State of Michigan, have invented new and useful Improvements in inking Mechanisms, of which the following is a specification.

This invention relates to inking mechanism for printing presses. 7

One object of the invention is to provide a pressure system for the feeding of ink.

Another object is to provide a circulating supply system for the inking mechanism.

Another object is to provide a system in AlilCll the inking mechanism may be easily cleaned or in which the color of the ink may be readily changed; and still other objects will appear in the following description and appended claims 7 Referring to the drawing: Figure 1 is an end elevation, pirtly in section of the improved mechanism; and Fig. 2 is a longitudinal elevation partly in section of the ink container taken on the line 2-2 of Fig. 1.

To reduce the inking mechanism to its simplest form an d to keep the ink in as good a condition as possible, the invention embodies means for supplying the ink under pressure in a closed conduit, and maintaining it in circulation in the conduit under any desired prcssurc so that the ink is at all times thoroi-lgiily mixed and is supplied to the inking mechanism in any quantity required.

As shcwu in Fig. 1, the ink may be stored in a supplytank aS at through which it is drmvn by )ump 11 through a pipe 12 and a port in tour way valve 13. The inkis delivered from. the pump at the outlet 14 through a conduit 15 into the sealed ink container 16. It passes through this container to conduit 17, through a pressure regulator 18 pipe 15) three \vayvalvc 20 and pipe 21 back into the ink supply tank 10. The pump is dri \"QII by any suitable mechanism and in the arraigcment shown, the actuation of the pump causes a continual circulation of ink through the ink container the ink beingmainta'iued under a pressure in the ink container that is regulated by the adjustment of the pressure valve 18.

The ink may be drawn from the container 16 and delivered to the distributing roll 22 by any suitable mechanism. The particular mechanism herein disclosed, described and claimed. in a copending application, Serial Specification of Letters Patent.

Patented June 6, 1.916.

1915. Serial No. 23,569.

I Number 1298, filed February 15, 1915, comprises a the ink through and a valve located within the port 23 is actuated by means of a plunger 25 which is" reciprocated by a cam 26 mounted upon a rotating shaft 27-. A series of these devices,

valve body 23 communicating with container 16 and with a duct 2i one for each column, is provided in order that the ink may be fed'in columns to the distributing roll .22. I

ln the arrangementdescribed, the ink is kept tree from contact with the air, and

until the time it is delivered to the distributmg roll, it is kept in continual movement so tlnit at all times it is uniformly mixed. This arrangement not only permits the delivery of ink under the most favorable conditions,

but it also permits the ready cleaning of the inking mechanism or of a change inthe color or character of the ink. F or this purpose extrasupply tanks with suitable connections to the pump 11 may be provided, one of such tanks being shown in the figure at 30. A

pipe 31 connects this tank with the' four way valve 13 and a. second pipe 32 connects the tank with the three Way valve 20. 1f the four way valve 13 be turned to close the passage 12 and to place the suction side of the pump in communication with the air, the pump will force all of the ink from the pipes and system back into tank 10. As shown in Fig. 2, the inlet 15 into the ink container 16 and the outlet 17 are so located with respect to each other that the ink in the container is displaced by air which is pumped into the container so that a few strokcsoi' the pump will drive all of the ink out of the system. If tank 30 be filled with benzin, or other cleaning fluid, and the four way valve 13 be then adjusted so that pipe 31 connects with pump 11 and valve 20 be adjusted so that pipes 32 and 19 are "in com:

munication with each other, then the actuation of the pump will cause a cut'sent of benzi n to flow through the system wh ith will work through the valve body 23 and ports in the inking mechanism, dissolving and rennoving any hard or cakcd deposit of inkfOB that may have been deposited in any parts of the apparatus, and Will carry such ink back to the tank 30. It will be seen by? this arrangement that all that is necessary to do to clean the entire inking mechanism of the press is to manipulate valves 13 and'2Q as described, keeping the pump 11 ingactuation,

which the ink passes to the roll 22, 60

the cleaning being accomplished conveniently in a very short space of time, and without disturbing the press. It is obvious that if tank 30 be filled with a different ink than tank 10, thearrangement provides a quick and easy method of changing the color or kind of irik delivered by the mechanism. It is also obvious that other tanks may be likewise" connected to the system so as to supply, other inks as desired.

'Yclaim:
