MAGAZINE INK-DISTBIBUTING DEVICE FOR PRINTING PRESSES.

Application filed December My invention relates to a magazine ink spreading knife particularly adapted for use on job printing presses.

The object of my invention, generally stated, is an ink applying and spreading knife or implement embodying an ink magazine incorporated therein as a part thereof and having means, including ink feeding and distributing passages leading from the magazine therethrough, for readily forcing the ink in the minute quantities desired through said passages and spreading the same over the disc or rolls of the printing press. A further object is a spreader of this character and of a construction enabling it to be readily lifted and manipulated by one hand, if desired, to supply the ink and spread it uniformly over the surface to be inked, and particularly a magazine knife of the character indicated which may be handled and manipulated with the greatest facility without the necessity of soiling the hands, thereby cconomizing the'time of the operator heretofore consumed in using the old cumbersome and more orless unsat1sfactory methods of dipping the old and ordinary spreading knife or wooden paddle into cans of ink and then smearing the ink over the surface, and also the time consumed in cleansing the hands which has heretofore often been necessary after the smearing operations before the job can be handled. A further object of my invention is to conserve the printing ink, and'this I accomplish by the economical manner in which, by the use of my invention, I am en abled to apply and spread the ink and also by avoiding the substantial loss by drying up in the air which has heretofore been eX- perienced with the open can dipping devices and methods. A still further object of my invention is a device of the character indicated which is of simple character and which may be economically manufactured and easily assembled for use.

For a better understanding of my invention, including the above indicated novel features and others which will hereinafter appear, reference maybe had to the accompanying drawings forming a part of this application, wherein a Fig. 1 is a plan view of'my novel maga- Zine ink knife,

member 1 in. the embodiment illustrated be- 7 ing of circular plate disc-like form and the magazine being of cylindrical form of substantially smaller diameter than that of the spreading disc. The spreadingmember 1 forms the bottom or the closure for one end of the cylindrical wall 2 of themagazine and, as illistrated in the embodiment of Figs. 13, the member 1 is screw-threadedlv attached and sealed to the cylindrical part 2 by means of an internally threaded sleeve 3 formed integrally with the memberl and cooperating with external screw-threads on the lower end of the cylindrical part 2. The cylindrical or tubular part 2 is screw-thread ed internally, preferably substantially throughout its length, for the reception of an externally threaded cylindrical member t having a. closed bottom 5, and in the embodiment of Figs. 13 this bottom 5 is integral with the cylii'idrical part 4 for convenience in manufacture. The member 4 serves both as a closure for the upper end of the cylindrical part 2 and as a plunger for applying pressure upon t is ink contained therein. Within the upper end ofthe inner part 4: of the device, there is disposed an externally threaded plug (5 which may be [inserted through the upper open end and screwed downwardly to the position desired. In the upper end 7 of this plug 6 there are provided radial screw-threaded openings, in the para ticular embodlment illustrated, four in all,

for the reception of the screw-threaded manipulating fingers 8, the latter passing out through openings formed near the upper end of the cylindrical inner member 4. The member 1 is provided with a number of small passages 9 (four in the embodiment shown) leading from the interior of the magazine 2 to the bottom surface of the spreading member, these passages serving as feeding andink-distributing apertures when the magazine knife is appliedto the surface to be inked and the feeding or inner member el is gradually screwed downwardly by the manipulation of the fingers 8 to apply pressure upon the ink. The device as a whole is providedwith a handle 10 which may be secured thereto in any suitable manner, as for example by brazing to the exterior of the'mcin'ber 2 with this handle proout at rightangles thereto and pera ready grip thereof by the hand, with the thumb free to manipulate the hugers 8 in the act of applying and spreading the inkon the disc or roll of the printing press. The relative dimensions of the parts may be varied within limits to suit the requirements of the )articular case, but those illustrated are preferred wherein the intermediate cylindrical wall 2 is of greater depth than diameter or width and the spreading and closing member 1 for the cylinder is of extended surface and of substantially larger area than the projection of the cylinder 2. In use the ink is contained within the cylindrical or tubular containing wall 2 of the magazine, and the bottom 1 and the inner and upper member 4 form tight closures therefor, thereby securing substantially air tight or leakless seals to prevent the leakageof the ink therefrom and the. entry of air thereinto, the drying up of the ink due to access to the air being substantially reduced and the ink thereby conserved. ltloreover, the device may be manipulated and adjusted during the actual application and spreading of the ink to feed and supply the exact quantities desired without any necessary waste of ink and without the necessity for soiling the hands. hen

'the ink becomes depleted, the device may be refilled either at the top or the bottom, namely by removing either the closing, distributing and spreading member 1 or by removing the inner member 4-, and when not in use the device may be suspended or laid in any position, as the ink will not ordinarily leak through the apertures 9 unless under pressure.

In Fig. 5 I have shown a slight modiiiczu tion wherein the spreading and distributing member 1 is brazed to the bottom of the magazine part 2 and the bottom 5 for the inner member 4-." is in the form of a plug or disc, fitting tightly within the lower end thereof and anchored in place by a pin 1]. passing radially therethrough and diametrically through the lower end of the inner member t. member a is provided with a single finger or handle 12 which passes through registering openings in the opposite sides of the up per end of the cylindrical member a and forms a pair of oppositely disposed manipulating handles for screwing the inner member l downwardly and feeding the ink in The upper end of the inner the quantities desired through the feeding passages 9. The device of this modification and the modification illustrated in Figs. 13 may be of any material desired, but preferably of readily workable steel.

In accordance with the requirements of the patentsta'tutes, I have set forth my invention in the specific manner required thereby, but it is understood that the novel features thereof are capable of assuming other forms than the specific embodiments illustrated, and that the claims annexed hereto are intended to cover all such modilied forms coming within the scope and spirit of my invention.

1 claim 1. An ink distributing device for printing presses comprising an ink magazine, a feeding plate forming a closure for one end of said magazine and having minute feeding and distributing passages leading from the ink magazine chamber therethrough to the surface of the closing plate, an adjustable closing and feeding member secured within the upper end of the magazine for both forming a closure therefor and applying pressure to the ink contained in the magazine to force it out through the aforesaid passages, an operating member for the adjustable closing member and a manipulating and lifting handle securedto the exterior of said magazine, said operating and manipulating members being arranged and adapted to be engaged simultaneously by the hand.
