INKING APPLIANCE.

To all whom it may concern:

Be it known that 1, ROBERT C. NEWTON, of Xeedham, in the county of Norfolk and State of Massachusetts, ajcitizen of the United States, have invented a new and useful Improvement in Inking Appliances, of which the following is a specification.

In printing telegraphic apparatus and other like machines where there is a. tape on which therecord is to be printed and a printing roller which must be kept properly inked to make the record, there have been various problems encountered in connection with the attempt to secure the application of the right amount of ink to the printing wheel with no danger of an oversupply. Attempts have been made to secure the desired result by the application to an ink reservoir of a valve of the needle type which being screwed down so as to nearly close the aperture through which the ink flows, is expected to allow only i the right amount of ink to pass. This has not been entirely successful for unless an air hole is provided the ink will 11Gb flow freely and the air hole allows a constant leakage of ink. When in the use of such a device the printin wheel is at rest perhaps for some considerable period of the day the ink is constantly leaking and causes an oversupply of ink on the printing roll and the blotting of the paper when the roller next attempts to print. A brush has been used for the purpose which brush has been put into the outlet of an ink reservoir and engages the printing roller. Here again the brush which may be of felt or the like becomes saturated unless there is a sufficient drain from it consequent upon the continued use of the printing wheel. Another means for inking the printing wheel is a felt. roller which rides on the wheel. This. however, is usually kept which the ink is daubed upon the roller by hand and this requires constant care on the part of the attendant.

My invention is intended to provide a means for inking a printing wheel which is adjustable so that the right amount of ink may be distributed and which also may be closed when it is desired to remove the device for refilling.

My invention will be understood by reference to the drawings in wh1ch Figure 1 is a Side elevation of my inking device upon a somewhat enlarged scale, Fig. 2 being a vertical section taken at right angles to Fig. 1, and Fig. 3 is a detailof the lower end of-my inker to indicate its adjustment. I

In the drawings I have shown merely a portion of a registering device of the general character above referred to, A being a frame mounted upon a base B.

C is a paper'tape of the usual character upon which the registry is to be made and a which is supplied'from a suitable reel as is customary 111 such lcvices.

'D, D are apair of feed rolls (a portion only of the roll I) being shown), between which the strip of paper C runs and by which it is drawn off the reel, (7, I]. being guides under which it is drawn.

E is the printing roll mounted on a shaft 0 and operated by any suitable means. Below it is a platen roll E which is free to turn as occasion may require. The tape of paper runs between these two rolls also and there is given to the platen roll E a vertical movement from time to time to impress the paper tape C against the printing roll E.

My. inking device is pivotally attached to the frame A by means of an arm, a, a being its pivotal attachment, as shown a screw. My ,inker comprises a hollow cylinder F the lower end of which is fiat. on its exterior. The chamber formed within the cylinder F is provided with a sloping or conical'floor f at the apex of which is a small opening f Thecylinder F is provided with a screw top F} having an air hole f sufficient in size to supply the slight amount of air necessary to compensate for the draft on the ink contained in the cylinder F and so prevent a vacuum. Down through the center of this cover F is a threaded opening within which screws a needle valve or plug G which is threaded on its exterior at its upper end to fit into the opening in the cover F its lower end 9 being pointed seas to fit into and close the hole f at the lower endzof thechamber F when desired. The top F Screwspnto the top of the cylinder F and is adapted to be removed when it is necessary to fill the chamber within the cylinder.

The lower end of the cylinder carries a collar H which is threaded on its interior so that its upper end may screw upon the threaded lower "end of the cylinder F. The threads in the collar H extend throughout its length and into the lower end of the collar H is screwed a plug J made of felt or other like substance which will absorb the ink ' collar II is screwed up tight so as to close the opening 1 by means of the plug J, In

, Fig. 2 there is a free opening for the ink to pass out into the space j between the top of .,the plug and the bottom of the cylinder and the space becomes a saturating reservoir for the ,plu hence the plug will ink the printingroller freely as may be required at cer-. .tain tunes in the day. During the times when the apparatus 18 not so frequently in use so that the printing roller requires less the collar H is screwed up tight carrymg the plug J with it. into the position shown in Fig. 2 where it closes the opening j, thus preventing any waste .of ink and also preventing the too frce'inking of the vprinting roller and the consequent blotting of the tape when the printing operation again begins. This plug therefore serves the double purpose of an inking pad and also of a plug to check the flow of ink. The arm a allows the cylinder perfect irecdoniof movement so that the device will always rest on the printing roller whatever may be the position of the plug J.

The embodiment of my invention shown in the drawings is simple, but I do not mean to confine myself entirely to it as my invention may be otherwise embodied, variations in the shape and general construction of its various parts being possible without departing from the spirit of the invention which relates to -the adjustment of the ink flow by' the location of the pad by which the print ing roller is inked. The apparatus is intended to be used with the ord nary ink used in such devices, the air hole furnishing sufficient air inlet. to allow the ink to flow out as needed. t

hat I claim as my invention is 1. An inker comprising an ink reservoir having an outlet through which ink can flow, and a pad, and means for moving said pad away from said outlet to form a space to receive and hold ink to saturate said pad and to "ard said outlet torestrict such saturation, as set forth. a

An inker comprising an ink reservoir having an outlet through which ink can flow, a pad and means for connecting said pad to said reservoir adapted to inclose a chamber one wall of which is formed by said pad and into which said outlet opens to supply said ink thereto, said means being movable to close said pad against said outlet. 3. An inker for printing rollers comprising a cylinder containing an ink reservoir, an outlet at the bottom thereof, means for closing said outlet and a pad located to receive ink from said outlet and movable to ward and from said outlet whereby it may serve to control the passing of ink from said outlet.
