Specification of Letters Patent.

TYPE-WRITING MACHINE.

Patented Feb. 22, 1916.

To all whom it may concern Be it known that I, L'ss'rnn A. VVnnNEnY, a. citizen of the United States, residing in Brooklyn borough, in the county of Kings,

city and State of New York have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to type-writing machines, and more particularly rto a. device for facilitating the writing of labels or other very small workpieces.

It is advantageous to hold the workpiece close to the platen, sothat the type impressions may be clear.

A feature of this invention is the provision of means whereby the small sheet or card may be held closely to the platen and written upon not only at the center, but also very close to all edges. The means for doing this may comprise a pair of springy clips which bear upon the workpiece close to the printing line. These clips may be provided with upwardly extending fingers at both their inner and outer edges.

, The adjacent or inner fingers lie close together, having only sufiicient space between them to permit the type to strike through. These fingers are fiat, and serve to protect the paper from being injured as the ribbon guide vibrates up and; down, and they prevent the ribbon from sniudging the paper. Theouter fingers are provided with flared portions to prevent the sheet from fouling thereon. The top edges of the clips, from which the fingers rise," also. have flared portitgns, to prevent the lower edge of the workpiece from fouling thereon. The clips and fingers may bev made of thin, springy sheet metal, and polishedgon their working faces.

Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a perspective view of certain parts. of an Underwood typewriting machine, showing my invention applied thereto. Fig. 2 is a front elevation, showing the type; and ribbon vibrator and ribbon in actuated p0sition;. the ribbon being shown in dot and dash lines- Fig. 3 is a side elcvation,.showing the relative position between the platen, the work and the clips.

In an Underwood typewriting machine, types 6. strike upwardly and rearwardly against the front face of a platen 7, or

upon the sheet thereon. An ink ribbon 8 is moved upwardly over the printing point at each type stroke by the usual mechanism, comprising a vibrator or guide 9, through which the ribbon is threaded. The workpiece is usually held to the platen by feed rolls 10 and 11. The platen is mounted on a carriage andis fed in letter-spaced direction by the usual mechanism.

A pair of clips 12 bear against the platen near the printing line to hold the workpiece close to the platen. These clips may be in the form of a pair of springy tongues, secured upon the frame 13 0f the machine and rising in front of the platen at either side of the printing point. Near their adjoining edges, these tongues are provided with upwardly directed fingers 14:, extend- .ing up beyond the printing line of the platen. These fingers are close together, leaving just enough room between them for the types to pass; and they therefore hold the worn-piece firmly while the types strike very close to the side edges. These fingers also serve to protect the worksheet from being injured when the ribbon vibrator is moved up and down. To aid the fingers in the support of th work-piece, the clips are provided at their outer edges with a set of fingers 15, rising from the tongues 12. Each springy tongue or clip and its fingers thereon has, at its upper part, a substantially U-sha-pe contour, as shown in Figs. 1 and 2. These fingers also serve to hold the work-piece so that the line of writing is visible to the o erator, and so that the operator mayeasi y aline the Work-piece by means of the scales 16, provided on flared portions 17, on the top edges of the tongues between the fingers 14 and 15. These scales have graduations whereby the operator may determine the number of line-spaces. The work-sheet is prevented from fouling on the paper fingers 15, by flared portions 18 provided thereon, and also on the upper ed es of the tongues 12 by the flared portions 1 which also carry scales. Upon their working faces the paper fingers 14k and 15 are preferably highly polished, so that when the Work-sheet travels with the platen in line-space and letter-feed movements of the carriage, the pressure of the paper fingers causes the work-sheet to travel with the platen. It has been found in practice that these trmo'noe edges regardless of the size of the paper label. Either of the middle fingers 14, it is seen, may engage the paper by a very small ,ii argin, thus enabling the type to strike lmost on the edge of the work-piece; and a similar result can be obtained at the top and 'o'tto'm, edges of the work-piece,

Variations may be resorted to within the cope of the invention, and. portions of the N I, nprovements may be used without others. Having thus descrihed my invention, I 2 r leim= a Lfln a typewriting machine, in combina- H ionwith a carriage, platen and frame, of a Jan of U-shaped spring clips secured to we frame in line with each other and in osition to contact with the platen, the adjaaii'cl theedges of the Us being flared.
