This invention relates to a copy holder carriage for typewriting machines and the like, and particularly that type which derives its operative movements from the line spacing mechanism of the typewriter upon which it is mounted.

The main object of my invention is to make it practical and conveniently possible to automatically and visually present upon a typewriter, line by line, and the precise portion or line desired of the copies to be transcribed by the operator, and to accomplish this so as to avoid skips, omissions and mistakes.

Another object is to facilitate copying and save time and work upon a typewriter.

Other objects and the advantages of my invention will appear more fully in detail as the specification proceeds.

In the accompanying drawings forming part hereof,

20 Fig. 1 is a front elevation of a copy holder carriage made according to the present invention and applied to a typewriter.

Fig. 2 is a rear elevation of the same apparatus.

25 Fig. 3 is a plan view of the same.

Fig. 4 is an end or side view on a larger scale demonstrating certain features of operation.

Finally, Fig. 5 is a cross section of the copy holder carriage as seen from the right side.

30 Throughout the views, the same reference characters and numerals indicate the same or like parts.

In the practice of my invention, the copy holder carriage is made of two principal parts A and 5 B, adapted to be mounted upon a typewriter C.

The first part A includes a pair of spaced parallel brackets I and 2 supported by a curved plate 3 and in turn supporting a rotatable shaft 4 of a feed roller 5 adapted to feed and support the 40 papers to be copied. At the two ends of the shaft 4 are secured the manual knobs 6 and 1 by which to turn the feed roller and insert the text to be copied. Upon shaft 4 and rigid with the base of the knob 6 is a ratchet 8 normally 45 retained in stationary position and actuated by a pawl 9 pivoted at If! to a movable bar ll. Said bar has a helical spring l2 attached to the same at one end, while at the other end is attached to bracket I. A spring I3 urges the pawl 9 downward and renders the same capable of actuating the ratchet 8 at will, by means of a member M by which the altitude of pawl 9 is adapted to be changed by means of a selective lever l5 in 55 order to cause the device to take any type of copy in the space between bracket I and ratchet 8, whether typewritten matter or manuscript.

The sliding bar II is actuated by the lever l6 having one end bent and connected with it and the other also bent and connected to another 5 sliding bar H, which forms a writing spacer for the copying text conveniently spaced with respect to the spacing lever of the matter to be copied from the typewriter, as shown in Fig. 4. The normal position of the sliding bar I! is obtained by a helical spring not shown or by any other means desired.

In the lower portion of brackets I and 2 is mounted a shaft l8 provided rigidly upon the upper portion with a plurality of small rollers l8, to which are attached a number of arms which are connected to a bar 20, which at the other end is attached to the second bar 2|. One of these bars 2! connected to the lever is capable of releasing the copy text by actuating lever 22, 20 which has a fulcrum of action at 23 upon plate or bracket 2 and is actuated by finger piece 24, as particularly shown in Fig. 5. Most of the parts are secured to the upper end of the bracket in order to protect the operating members and a 25 cover 25 serves for this purpose, while the front of the carriage is covered by two metal plates 26 and. 21, the first being rigid and the second being slidable and when opened serve to disclose a small window 28, whose altitude can be changed by means of toothed wheels 29 and 30 mounted in the lugs 3|. Said toothed wheels 29 and 30 cooperate with racks 32 and 33 respectively, which are connected to the sliding plate 21.

In order to feed the paper of the typewriting machine upon which the invention is mounted,

a curved plate 34 is provided to expedite movement of the paper. Upon the rear of the curved plate 34 are attached two pieces 35 and 36 at one end, while at the other ends they are attached to a bar 31, from which extend a pair of bent arms 38 and 39 that project downwardly in the form of hooks carrying a rotatable sheave 40 running upon one of the members of part B to be later described. To the member 31, two or more members 4| connected with pressure screws 42 serve to actuate the members of part B and render the movements of the copy holder carriage reliable and. the carriage in rigid adjustment in position.

The part B of the invention comprises two brackets 45 and 46 as secured together by two round bars 41 and 48, the first bar serving as the base for the pressure screws 42 and the other bar serving as a rail upon which the small sheaves 4!] may run. The brackets 45 and 45 are articulated to supports 49 and 50 and mounted directly upon the typewriter frame and retained in posi tion by means of screws 5| and 52 in said supports 49 and 50, The supports can, of course, be merely placed upon the typewriter and allowed to slide back if desired. The main connection between the two parts A and B comprises the sheaves 40 and the pressure screws 42 already described.

If the device is mounted upon the typewriter, it is but necessary to insert a paper 53 upon a typewriter C in order that at the rear of the machine it will be accommodated between the curved plate 3 and the guide plate, as shown in Fig. 4. Then the copy text 54 isintroduced at the rear of feed roller.5 by turning the knob 6 or I and utilizing lever 22 to adjust as though placing the paper in position upon the platen of a typewriter. When in place, it is but necessary to allow the small rollers l8 again to come into action by releasing the lever 22 so that-the paper .will appear at the desired portion to be copied.

The lever l5, which'actuates the sliding piece I4, serves to limit movement of bar ,ll adapted to operate pawl 9 upon movement .of lug member 16, so as to cause ratchet wheel 8 to rotate in order to successively feed the copy material line by line to the desired position as the work proceeds.

However, the knob 3| upon the lug 9| serves to elevate the window 28 to proper position so as to show line by line the text to be copied.

When the paper in the typewriter and the copy text in the copy holder carriage are adjusted to .the respectively proper positions, one for reading and the other for typing, the line visible in window 28 will be the first to be copied and when fed forward a line by allowing the line space lever claim:

A copy-holder carriage for typewriters, comprising the combination with a line spacing lever on the typewriter, of a frame for mounting upon the typewriter having a pair of spaced horizontal rails, a second frame surmounting the first and having sheaves rolling upon one of said rails and adjustable members adapted to engage with the other rail, there being spaced brackets on said second frame carrying a paper feeding roller provided with manual means for turning the same, manually operated paper release and engaging 'means, line spacing means for said feed roller, and means engaged by said line spacing lever of the typewriter actuating the line spacing means of the feed roller upon said. second frame, an adjustable manual selecting lever pivoted upon said second frame and connected to a slidably movable'member, the line spacing means for the feed roller on said frame'including a ratchet rotating rigidly with said feed roller, and a pawl engaging said ratchet pivoted upon said slidably movable member, said last mentioned movable member being capable of changing the v altitude of said pawl upon manipulation of said selecting lever, and there being a spring urging said pawl into engagement with said ratchet.
