RIBBON-INKING ATTACHMENT FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent No. 341,630. dated May 11, 1886.

Application filed August 3, 1885.

To all whom it may concern.-

Be it known that I, LEONARD BAILEY, of Hartford, county ofHai-tford, State ofCon uectiout, have invented certain new and useful Improvements in Ribbonlnking Attachments for Typewriters, of which the following is a de scription, reference being had to the accompanying drawings, where- Figure l is a plan or top "iew of part of a type-writing machine of the kind known as the Caligraph, with my improved device attached in position for inking the ribbon. Fig. 2 is a view in central vertical section through the reel, thetype-writer frame, and the inking attachment. Fig. 3 is a detail perspective view, on enlarged scale, of the frame used to hold the rolls. Fig. 4 is a detail seetional view of the inking-roller and its cover, the latter being removed.

The object of my invention is to provide means for inking the ribbon of a typewriting machine without removing the ribbon from the reels on the machine; and to this end my invention consists in the novel construction of parts and their combination, as will be hereinafter fully described, and specifically pointed out in the claims made thereto.

In the accompanying drawings, the letter a denotes the frame of one of the class of typewriting machines known as caligraphs, so much only of the frame and the operating parts of the machine being shown as is necessary to illustrate my invention.

The letter 1) denotes one of the ribbonreels appurtenant to the machine, and c the ribbon, which is of usual form and material and is stretched across the machine between the two ribbon-reels on its opposite sides, in the usual manner.

At one side of the machine, about in line with the carriage and in the same vertical plane with the ribbon, is supported an inking roll, (1, preferably by securing it in bearings in the roller-frame e, that is detachably secured to the frame of the machine a. This rollerframe 6 is made, preferably, of metal, cut or cast to shape, with the base 6, the arms 6-, extending from the base, and the clamp f. The latter in the form shown consists of the clampscrew f, that is seated in a threaded socket in the downturned flange on the base of the frame Serial No. 173,327. (No modeLl and cooperates with the flange or pin 6 in attaching the roller-frame to an object. On

the arms 6* are formed the bearingsgg, for the inkingroll d and the guide roll d. The upper part, 6, of this roller-frame corresponds with the lower part in general outline, and is reinovably secured to it by means of the screw 71, the several parts being clearly shown in Fig. 3.

The pins that form the bearings g are long enough to project through the holes 9* in the upper part of the frame when'the latter is secured to the lower part, and thus the two parts are kept in proper relative position.

The inkingroll d is made up of the tubular central ink-receptacle, (1 having in its walls a number of perforations, d, and this ink-receptacle has a porous cover, (1, compl'etely inclosing it on the outside and extending between the end flanges, d d", of the roll. This porous cover d of the roll is preferably made of felt, which is sufficiently porous and absorbent and retains in about the proper de gree the ink which flows into it from the inside of the receptacle within the roll, but any material other than felt having such qualities may be used equally well in its place as a cover. The roll is provided with the central pivots, (1 one borne on the fixed end and the other on the removable end, which is held, preferably, by the screwstem extending within the threaded socket in one end of the receptacle.

The ink-roll is preferably protected when not in use for inking purposes by means of a tubular cover, (i that may be slipped upon the roll from either end, and is preferably of metal.

' The guide roll d is of any convenient material-as metal-has suitable pivot-bearings, is preferably of the same size as the inkingroller, and is mounted in the frame by the side of the inking-roll, as shownin the accompany ing drawings. The office or function of the guide is to change the direction of the ribbon, so as to bring its upper surface in contact with the ink-roll. This guide-roll is not essential to the operation of my device, as the ribbon is usually absorbent enough to enable the ink that is applied on one side to pass through it and thoroughly permeate it, so that either side purposes part of the frame secured to the frame of the typewriting machine. A loop of the ribbon is then passed over the inking-roll, which is placed in the bearingg in the frame,and another loop under and over the guideroll, which is then placed in its hearings in the frame. The cover-plate is then secured in position, as illus trated in Figs. 1 and 2, and by turning the reel the ribbon is drawn back and forth over the inking-roll, the cover of which was removed, of course, before placing it in position for use. By reversing this process the rolls may be removed from the frame, the cover of the inking-roll placed in position, and one or more of the rolls, replaced in the frame, to serve as supports or guides for the ribbon in place of the usual wire which holds it at the proper height for use in the machine.

I do not limit myself to the particular form of the roller-frame or to the particular construction of the ink-roll herein shown and described, as it isevident that the form of the frame and the relative arrangement of the rolls can be changed without, however, the exercise of invention to adapt the frame or rolls to different kinds or forms of type-writing machines.

By the term ribbon-reel, as used in the following claims, I mean to be understood as claiming in the combination with the other elements the reel or any equivalent support for the ribbon in its passage through the machine.

I claim as my invention- 1. The combination, with the ribbon and ribbon-reels of a typewriting machine, of a removable frame bearing the inking-roll and the guide-roll, and a clamp whereby said frame is attached to the frame of the machine, all substantially as described.

2. In combination with the ribbon and ribbon-reel of a type-writing machine, the rollerframe with the clamp for attaching it to the machine, the removable upper part of the frame, and the ink-roll held in bearings be tween the parts of the frame, all substantially as described.

3. In combination, the roller-frame with the clamp device, the removable upper part of the frame, the guide-roll, and the ink-roll with the central perforated ink-receptacle with porous and absorbent cover, the rolls being supported in bearings between the parts of the frame, all substantially as described.

LEONARD BAILEY.
