ROLL-CHART HOLDER.
Application mea July 27,
To all/whom it may concern.'
Beit known that we, SYLVAN RosEN'rHAL, a citizen of the United States, residing at Philadelphia,- count of Philadelphia, State of Penns lvania, oRRIs SUBBER, a citizen of the dephia, county of Philadelphia State of Pennsylvania, and HARRY A. OSENTHAL, a citizen of the United States, residing at l0 Philadelphia, county of Philadelphia, State of Pennsylvania, have invented' a new and useful Roll-Chart 'Holder, of whiclrfthe following is a specification. r-
Uur invention consists of a novel construction of roll chart holder. The holder is adapted to stand in the rear of a typewriter, so asy to be Visible to the operator, and comprises a supporting frame having mounted therein a pair of feed rollers upon which feed rollers is mounted an apron or ribbon containing instructions or printed or typewritten matter for the typewriter student. Means are provided for frictionally braking or arresting the movement of said rollers so that the rolls and the typewritten matter are ,temporarily held at any desired point, in order that the learner who is operating the typewriting machine may see the instructions and' typewrite them. Provision is made at the upper portion of the frame for supportinga suitable chart.
Our invention further consists of other novel features of construction and advantage all as will be hereinafter fully set forth.
For the purpose of illustrating our invention, we have shown in the accompanyingdrawings a typical embodiment thereof which 'is at present referred by us, since this embodiment will he found in practice to 40 give satisfactory and reliable results. It is,
however, to bev understood that the various instrumentalities of which our invention consists can be variously arranged and organized and that ourA invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.
Figure 1 represents a perspective view of a roll. chart holder, embodying our invention, the relative position thereof with respect to a typewriter being shown, the typewriter and an additional chart being indicated in dotted lines.
Figure 2 represents a vertical partly scc-v nited States, residing at Phila- 1922. Serial N0. 577,846.
tional view through the frictional braking device for the feed rolls.
Figure 3 represents a vertical sectional view showing the opposite or right-hand,
.secured at their upper portions by'a screw 4 to their respectlve uprights 2 and are tied together at their bottom portions by the horizontal brace 5, whose central portion is secured to the lower portion of the standard 2,`as indicated at 6, and its en ds are secured to the feet 3 by the fastening dey y vices 7.
About midway of the height of the standard 2, we locate the plate 8 having the outwardly extending upwardly bent portion 9 above which is located the rupper feed roll 10 and the lower feed roll 11. The top edge of the upwardly bent portion 9 terminates in proximity to the bottom of the roll chart or instruction chart 30 to be hereafter referred' to and servestol form a guide or line over which the printed instructions on the roll'chart can be readily read by the student, as he operates the typewriter, while the plate 8, serves to tie to-` gether the intermediate portions of the uprights 2, as is evident.
The feed roll 10. is mounted upon the trunnions 12 and 13, while the lower feed roll 11 is mounted onthe trunnions 14 and 15, said trunnions 12 and 14 being mounted in a vertical plate 16, in proximity to which is the braking or clamping device composed of the members 17 and 18, which are held in their adjusted position by the screw 19.
The upper portion of the clamping member 17 has the concave portion 20, which is adapted to engage the upper roll 10 and the lower portion .of said member 17 has the concave portion 21 adapted to engage the lower roll 11.
The upper portion of the clamping member 18 has a concave portion similar to the part 20 already described, which is adapted to engage the upper inner end of the roll 10 and at its lower portion is the lower concave portion 23, which is adapted to engage the lower inner periphery of the lower roll 7. l The upper roll 10 is provided with the finger piece 24, which is attached to the upper trunnion 13 while the lower roll 11 is provided with the finger piece 25, which is attached to the lower trunnion 15. The trunnions 13 and 15 are mounted in a plate 26 carried byl an upright 2 and the plate 26 is provided with laterally extending slots -27 which open through-its front edge so that is retained in .position between the flanges 32 of the angles which form the uprights and theguides or keepers 33 which, as illustrated, are in the form of wires having their ends deflected and ,secured inl a side flange of the uprights. The chart 35 is lshown in doti ted lines in Figure 1 and bears representation of hands with indicia, shown in part, indicative of the keys to be struck by the respective lingers. 34 is an upper cross bar. It will be apparent `that any kind of a roll chart desired may be employed on the rollers 10 and 11 and that by revolving one roller` or the other the portion on the chart will be readily visible to the student so that the proper instructions can be given without the necessity of an instructor being present. The .braking action on the rollers 10 and 11 can be adjusted as desired by means of the fastening device 19.
It will now be apparent that we have devised a novel and useful roll chart holder which embodies the features of advantage enumerated as desirable in the statement of the invention and the above. description, a-nd while we have, in the present instance, shown and described a preferred embodiment'thereof which will give in practice satisfactory and reliable results, it is to be understood that this embodiment is susceptible of modification in various particulars withoutdeparting from the spirit or scope of the inventionl or sacrificing any of its advantages. v
Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is: v
1. In a device of the character stated, a
-pair of uprights, a forwardly projecting arm carried by each upright, upper and lower rolls rotatably mounted in said arms, a roll chart carried b said rolls, a. finger piece for each of sai rolls for actuating said chart in either direction, "a horizontal bar connecting said uprights and arranged in proximity to said arms, and keepers connected to said up-rights above said bar and adapted to retaina card in vertical position upon said horizontal bar.
2. In a device of the character stated, a
pair of uprights, a forwardly projectingl and between said keepers and said top bar.
3. In combination, a pair of pjarallel posts, a cross bar at the lower end of each post, a pair of upwardly converging legs associated with each post and having their upper ends connected to the respective post. and their intermediate portions connected to the outer ends of the cross bar, a forwardly projecting armcarried by each post, rolls rotatably mounted in saida-rms, a bar connectl ing the posts and arranged above said arms and forming a horizontal support, and keepers connected to they posts above the last mentioned bar and adapted to retain a card inyposition u on said supporting bar.
