INKII TG ATTACHMENT FOR TYPE-WRITERS.

Specification of Letters Patent.

Patented Apr. 15, 1919;.

This inventlon relates generally to the class of printing machines and particularly to that type of maolhine employing or making use of an inked ribbon or ink transferring surface whereby the impression of type can be carried on to a sheet or surface arranged in the presence of the type and more specifically typewriting machines. Ordinarily a machine of this style uses an inked ribbon, a fabric saturated with an ink prepar'ation in which the ink preparation is frequently entirely utilized before the fabric of the ribbon has-been destroyed through ordinary use. Owing to atmospheric conditions, certain typewriter ribbons dry out and it becomes impossible to convey to a paper sheet or .the like, clear, sharp and strong typewritten impressions. In the present typewriter ribbon the amount of ink contained in the fabric gradually diminishes as the same is used and the type impressions are consequently fainter and lighter. I have therefore constructed an attachment which can be quickly applied to a printing machine such as a typewriter and arranged whereby the commercially inked ribbon can be freely passed over an ink distributer, the ribbon finding frictional confinement-against said distributor whereby a new surface of the latter is presented to the ribbon intermittently as the type bars of the machine are actuated, there being associated with the distributer an inking surface which is adapted to permit a quantity of ink to be transmitted to the former to take the place of that bodyof ink which has beenconsumed through use or rendered ineffective through drying up. In this manner, means are provided whereby the ribbon will always be pomessed with a freshly inked surface so that the type impressions when placed upon the paper sheet will appear strong: and prominent during the entire life of t e ribbon. Furthermore, by strengthening the fabric of the ribbon, I can, through use of the presentattachment, greatly'increase the life of the ribbon An important object of the invention resides in the provision of an inking attachment which will be absolutely automatic in its operation to convey to the printing ribbon a small quantity of ink only as the machine is operated, and one which will prevent the feeding of ink to the ribbon when the machine is not in use.

Most typewriting machines now in use are equipped with multi-color ribbons, such as black and red, black and purple or any other variety of distinctive colors, means being included in the machine whereby at the election of the operator a selected color or portion of the ribbon can 'be accurately associated with the type bars and correspondingly colored written matter set upupon the sheet to be printed. I therefore include in my inking attachment a selective mechanism in which containers for inks of distinguishing colors can be singly advanced into coacting engagement with the distributer above referred to.

A still further object of the invention is to provide an inking attachment in which theink delivering containers can be rendered inactive relative to the distributer at the will of the operator so that nothing but carelessness on the art of the operator will result in an over in ing of the ribbon.

Another object of the invention resides in the provision of an inking attachment which will consist of a principal part includin an active distributer orink receiving sur ace and a destructible and permanently sealed ink container which is freely removable from the structure whereby when utilized it may be replaced by a new one in an expeditious manner, the container being desi ed to contain only a suflicient quantity 0 ink which will benecessary to supply the ribbon with a propersupply of ink during the entire life of the fabric.

With the above and other objects in view which will appear as the nature of the invention is better understood, the same-consists in the improved construction and novel arrangement of parts which will be lhereinafter fully described and particularly pointed out in the claims.

distributer.

' The typewriter shown in the drawings is to be considered as merely a method of conveying or illustrating the use of the invention. I do not wish to limit myself to the use of the attachment in connection with typewriting machines as it may be satisfactorily employed in connection with multigraph machines and in fact any machines employing an inked ribbon from which impressions of the type are adapted to be carried on to a. paper sheet or the like. The typewriter includes all of its usual elements such as the spools or reels A and B, and the ribbon guide G, whereby the ribbon can be wound from one of said reels to the other as the occasion demands. In addition to the guide C, the frame D, of the machine includes guide brackets EE, and passages F, therebeneath through which the ribbon is adapted to pass.

The inking attachment consists of a bracket 1, having a relatively large barrel or cylindrical-like distributer 2, the peripheral surface of which is covered with a pliable material such as rubber or any other composition of matter which will freely receive the ink and then ermit the same to be transferred to the rib on. The distributer is provided with side flanges 3-3, which serve to hold the ribbon uniformly against the periphery of the distributer as will be understood. This distributer is mounted to freely revolve from a shaft 4, carried by the bracket 1. To one side of the distributer are ink containers 5 and 6, the same being arranged in superposed relation and preferably .in advance of the ribbon reel A, of the typewriter. Each of these containers is revolubly supported from a shaft 7, mounted upon a rocker 8, the latter having pivotal connection at 9, with the bracket 1. 'Said shaft 7, extends through an arcuate guide slot 10, in the bracket as clearly illustrated. In this manner, the rockers can be adjusted at the will of the operator whereby the ink containers can be either singly or simultaneously brought into contact with the distributer 2. l/Vhen it is desired to apply ink to the ribbon, one or both of the containers as may be required, are made to contact with the peripheral surface of the distributer 2. By adhesion the ink will be taken from the containers and delivered to scribed arrangement of perforations, it is evident that two kinds of inks will be' applied respectively to two diflerent parts of the surface of the distributer 2. Each container is provided with permanently sealed crowns 1212, through which the shaft 7, passes loosely. The inner ends of the shafts of said containers have threaded connection in nuts 13, carried by I the rockem 8. The outer ends of the shafts are provided with manipulating enlargements which can be convemently. grasped by the fingers when it is desired to apply the containers to or remove the same from said rockers. The ink used in connection with the device is of a rather thick consistency; and in order that it will be fed through the perforations in the containers, I provide the shafts 7, with radial arms 20, having substantially V-shaped ends or heads providing angularly disposed surfaces 20, which operate to press the ink against the inner walls of the container and to satisfactorily force the ink through the perforations.

Each rocker is provided with an actuating arm 14 extending beyond one side. of the bracket 1, where it may be conveniently moved by hand when it is desired to effect an adjustment of the container with relation to the distributer 2. The nuts 13, have thethis arrangement, the containers are held in positive frictional contact with the peripheral surface of the distributer 2, when said containers are adjusted for the purpose ef'z'" supplying said distributer with ink. In

order to hold the rockers against the actionof the springs 15, I provide spring latches 16, upon the bracket 1, having pins 17, which extend through passages in the bracket so that they can come across the portion 14, of the rockers to obstruct the movement of the latter. Slight pressure of the hand against the portions 14, permits the same to freely pass over said pins.

The distributer 2, is arranged in line with the reels A, and'as the ribbon is paid from said reel, it is passed over an idle roll 18 on the bracket and then over the distributer 2, and finally over a second idle roll 19 on said bracket 1, and thence through the usual ribbon guide passages in the frame ofthe typewriter. In this manner the ribbon is held moose with the inking surface of the mentioned distributer 2. k

While I have shown the attachment ap. plied .to that design of typewriter machine using a vertically mounted ribbon reel or spool, it is desiredthat it be fully understood that the same is not to be considered as a-necessary attachment will be just as effective for the purpose typewriter irrespective of the angle or position at which the ribbon reel is supported. That is to say, it can be used in connection with horizontal reels, angularly mounted.

reels and also inclosed reels as will be understood.

I wish also to say that my invention can be applied to a previously inked ribbon as well as to an un-inked ribbon and in the latter instance, the perforations in the con-- tainer can be enlarged to permit the ink to v fiow more freely on to the ribbon. What is claimed asnew is 1. An inking attachment for typewriter ribbons comprising, a revolubly mounted ink;
