UNITED ST LOUIS M. SNYDER, OF BROOKLYN, NEW YORK.
T-YPEWRITER ATTACHMENT.
Application filed November 17, 1925. Serial No. 69,685.
The attachment of the present invention relates to that class of devices which serve to mount a roll of paper in operative position to befed under the platen of a typewriting machine, and includes means for.
shifting the paper roll as the platen carria e of thetypewriter shifts.
feature of the present invention is the novel method by which I support the paperroll in such a manner that little additional weight is added to the platen carriage dur; ing its normal shifting movement, and the added work necessary to shift the platen vertically when changing from one style of type to another is comparatively negligible.
An object of the invention is to provide an attachment of this character which may be conveniently associated with any standdid make of typewritting machine, which will be of simple, practical construction, and yet rugged, durable and efficient in use.
A further object is to provide an attachment which may be applied to a standard make of machine in a very short time by an ordinary typewriter mechanism, or an attachment which may be built into a standard make of machine at slight expense.
With the above noted and other objects in iew, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter set forth and pointed out in the claims. The invention may be more fully understood from the following der: "ription in connection with the accompanying drawings, wherein F'gl l is a somewhat diagrammatic side :levational view of a typewriter showing my improved attachment in applied position. In this view, the platen carriage and paper all carriage and their guides have been shown in section.
Fig. 2 is a view in rear-elevation of the v:aachine.
Fig. 3 is..a fragmentary top plan. view '-":iereof.
For the sake of clearness I have omitted -fi1OWiIlg many of the standard parts of the ypewriter 10, but have indicated the supparting feet 11, the platen 12/ mounted in 1: 2 carriage 13 whichotravels on roller bearings in a guide way 14. As thus far described the machine is entirely conventional, the present invention being more particularly concerned with the provision of means for supporting a paper roll 15 from which an endless roll of paper is fed to the platen,
and by virtue of which, the necessity for frequently inserting new sheets under the platen when taking dictation on the machine, is eliminated.
A supplemental frame work inchides hori zontal arms 16 secured in any suitable manner beneath the typewriter 10, and projecting rearwardly therebeyond. The ends of these arms cooperate with supporting feet or blocks 17 to mount a roller bearing guide way 20 at the rear of the machine. Slidable transversely on this guide way is a carriage 21 for the paper roll, said carriageincluding vertical standards 22 having bayonet slots or other suitable openings 23 therein for receiving the trunnions 24 of the paper roll 15. Near their upper ends the standards are connected by a transverse rod 25 which serves to brace the standards 22, and which also serves as a guide over which the paper web 15 is trained.
It will be noted that the standards 22 are formed in their upper ends with relatively deep notches 26 straddling the intermediate portion 27 of a frame member attached to the platen carriage 13 and otfsetrearwardly from the platen carriage. This frame member' includes angular 'end portions 28 secured as at 29 to the platen carriage and extending from their point of connection with the carriage to the forked ends of the standards 22.. Itwill thus be seen that the angular ends of the frame 28 by virtue of their engagement with the standards, effectively prevent independent lateral shifting movement of the two carriages 12 and 21. When the platen carriage 13 is shifted in either direction, the paper carriage/21 is caused to move therewith. The only power necessary to efi'ect shifting of the paper carriage however, is the power necessary to slide this carriage laterally on its roller bearings. Thus there will be no material strain imposed on the typewriter escapement mechanism, and no great load on the platen carriage as it is manually pushed from left to right by a typist. The paper web 15 is trained over an additional horizontal guide bar 30 mounted inshort standards 31 projecting upward- 1y from the ends of the angular portions 28 of the frame bar 27. The paper web is trained behind the guide bar 25 over the guide 30 and then entered under the platen 152 in the usual manner.
The use of some construction which permits the typewriter carriage to be lifted independently of the paper carriage is highly desirable. Otherwise when operating the shift key for shifting from small letters to capital letters on the key board of the typewriter, the entire weight of the paper carriage and paper roller would be sustained by the platen, and would render operation of the shift key difficult. By virtue of the present construction, the only portion of the attachment which lifts with the platen carriage is the frame 27 and the paper guide 30 which it carries. The fork 26 permits the frame bar 27 to rise without actually leaving the fork. It will be noted that I have shown no retarding means to regulate unwinding of the paper roll, and that consequently there will be no material tension on the web 15 to load the shift key as the platen is lifted.
It will be obvious that instead of a forked construction, the standards 22 might merely be slotted to allow for movement of the bar 27, and that various changes and alterations might be made in the general form and arrangement of parts described, without dearting from the invention. Hence I do not wish to limit myself to the details set forth, but shall consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
I claim:
1. The combination with a typewriter, including a platen carriage, of a paper roll carriage connected to the platen carriage for movement therewith as the platen carriage is shifted laterally, and means permitting free vertical movement of the platen carriage independently. of the paper roll carriage, said means including arms on the platen carriage engaging thepaper roll carriage to shift the same as the platen carriage shifts laterally and working in slots in the paper roll carriage as the platen carriage shifts vertically.
2. The combination with a typewriter including a platen carriage and platen, of a paper roll carrying attachment including a carriage, standards in the carriage between which a paper roll is mounted, a frame offset rearwardly from the platen carriage and engaged with said standards to compel simultaneous lateral shifting movement-of the two carriages, said frame including angular arms working in slots in the standards to permit lifting of the platen carriage inde' pendently .of the paper roll carriage.
3. The combination with a typewriter including a platen carriage and platen, of a paper roll carrying attachment including a carriage, standards "in the carriage between which a paper roll is mounted, a frame ofi'set rearwardly from the platen carriage and engaged with said standards to compel simultaneous lateral shifting movement of the two carriages, said frame including angular arms working in slots in the standards to permit lifting of the platen carriage independently of the paper roll carriage, paper guiding means carried by the standards and said frame.
4. The combination with a typewriter including a platen carriage and platen, of a paper roll carrying attachment including a carriage, standards in the carriage between which a paper roll is mounted, a frame offset rearwardly form the platen carriage and en gaged with said standards to compel simultaneous lateral shifting movement of the two carriages, said frame including angular arms working in slots in the standards to permit lifting of the platen carriage independently of the paper roll carriage, a paper guide bar connecting and bracing the standards-adjacent their upper ends.
5. The combination with a typewriter including a platen carriage and platen, of a paper roll carrying attachment including a carriage, standards in the carriage between which a paper roll is mounted, a frame offset rearwardly from the platen carriage and engaged .with said standards to compel simultaneous lateral shifting movement of the two carriages, said frame including angular arms working in slots in the standards to permit lifting of the platen carriage independently of the paper roll carriage, short posts rising from the offset frame, a paper guide bar mounted on said posts, and a paper guide bar mounted between said standards.
6. A device of the class described in claim 2, and wherein the upper ends of the standards are forked to define the slots which accommodate the angular arms.
