PATENT OFFICE 2,128,304 COPY HOLDER FOR TYPEWRITERS AND OFFICE MACHINES Paul Kobler, Lynbrook, N. Y. Application October 5, 1936, Serial No. 104,089 5 Claims. (Cl. 120-28) - My invention relates to improvements in. copy holders, particularly in new means for holding a sheet or number of sheets of manuscript or other writing, while being copied from by a typewriter '5 operator whereby time and labor are saved and mistakes avoided. My invention will be understood by reference to the accompanying drawing, where the same parts are indicated by the same numerals 10 throughout the several views. Fig. l is a perspective view of the copyholder with the paper holding members. 1 Fig. 2 is an enlarged side view of the paper holding member with attached weight. 15 Fig. 3 is an enlarged side view of the paper holding member without attached weight. The copyholder shows the application of ?ngers ger pieces will open by itself if a paper is pushed underneath. No extra movement or lifting of the paperholding clip is necessary. On the other hand, once the paper is under the paperholding clips they can not be pulled down anymore. As ‘5 said before the support of the paperholding clip is bent out at II so that there is» an eccentric action on the rubber piece of the ?nger and bar 55 on the copyplate. . When pulling the paper downward from under- ‘10 heath the ?ngers I and 2 the supports II would bend outwards and the eccentric action of the ?ngers would be lost if the supports I I would not be held in position by the ?at piece I4, over which the supports slide. Further describing the p-aper- >-'1-"5 holding clip and its mounting on. the support, it is quite important that the ?nger parts I and 2 with I and 2 held in position by a support. the rubber pieces are standing out, away from The ?ngers I and 2 are constructed preferably the supports II. This allows the paper, placed 20 with a rod. This rod or ?nger‘ has at its end a ’on the copyholder plate to go far under the ?n- ‘:20 rubber II] which prevents the paper from slip gers I and 2 and allows also to pull the paper on ping out underneath the ?nger. the copyplate to any height desired. Fingers I and 2 together with their support Bar I2 of the paperholding clip can not slide ing means 3 and 4 can be moved from “A”—“B” .25 ‘or “C”—“D” respectively. Parts 3 and 4 are bent forward at II. The supporting means with ?n gers (paper holding clips) I and 2 slide from “A” to “B” and from “C” to “D” on bar I4. This bar I4 is through a rod I5 so constructed that the 1.30 two ends “A” and “C” can hardly bend and will always remain in a very straight line. This is necessary so that the supporting means 3 and 4 can easily slide from “A" to “B” and “C” to “D”. The same construction of bar I4 with rod I5 is 35 repeated with bar I6 and rod I ‘I. Bar It forms: a part of the copyholder plate I8 and is rein forced by rod IT. The paper holding clips I and 2 are kept in position by the weight of the rod I2 which at 40 one end is bent (32 and 33) to make this rod heavier and at the same time holding it from ?apping over backwards. The bent parts 32 and 33 are so long that they touch bar It when folded upwards. 45 ' The paperholding rod I2 with its ?nger pieces I and 2 is pivoted in its support I I. The ?nger pieces I and 2 of rod I2 touches the copyplate or bar I6 above the pivoted point. This upward inclination of the ?nger pieces I and 2 is the most important part of the paper holding clip. A rubber attached over each ?nger piece will hold any paper tight to the copyplate or bar I6. The upward inclination of the ?nger pieces I and 2 which can be seen especially well 55 in Figs. 2 and 3 has the advantage that the ?n out of support II as on one side of support II the paperholding clip is bent backwards and on the 25 other side bar I2 has a pin to prevent any slid ing out of support I I. The main feature of support I I is that this sup port is not pivoted on bar I4. On the contrary the flat side of bar I4 prevents support II from 430 bending outwards so that the rubbers on ?ngers I and 2 get a very strong eccentric action on the copyplate. The more the paper is pulled down ward from underneath the rubber ?ngers I and 2 the more the eccentric action of these ?ngers 35 hold the paper tight on its place. The operation of my device is as follows: An unusually large sheet is placed on copyplate I8. Fingers I and 2 with. their supporting means are so designed that they can take care of un- 40 usual paper sizes. The ?nger supporting means Ii slide for this purpose from “B” to “A” and from “D” to “C”. The position of ?ngers I and 2 shown in Fig. 1 is ready for the largest sheet. But the smallest 45 sheet can be taken care of, if we slide the ?ngers I and 2 towards “B” and “D” together with their supporting means II. These ?ngers I and 2 Work like eccentric levers, as shown in Fig. 2 and Fig. 3. At the end, Where 50 they touch the copyplate they are provided with a rubber I0. ' These ?ngers I and 2 hold in their position by their own weight. For single small sheets the weight of the small 55 2,128,304 ?nger itself is su?icient and if a special copy holder for small work would be needed, such a ?nger could be made out of a straight piece of rod or~bar and could be pivoted at its opposite end, as shown in Fig. 3. For heavier papers or bunch of papers the weight of the ?ngers I and 2 has to be heavier. Bar I2 forming at one end ?ngers I and 2 is therefore bent at the other end, preferably backwards in such a way, that the weight of ?ngers I and 2 is increased. At the same time this backward bent part No. 32 and 33 in Fig. 1 and 32 in Fig. 2 holds the ?ngers I or 2 from turning all the way over, when a piece of paper is pushed under the rubber parts. With other words the ?ngers I and 2 are by 15 their own weight steadily pressed against the copyplate or bar I6 in Fig. 1. It is possible to slide one or several papers at a time under a ?nger, but it is impossible to pull the papers 20 back. Herein is the greatest advantage. The papers may be pulled upwards. In any position the ?ngers are always ready to hold the paper tight. The papers may also be taken out side wards very easily. But the more the paper pulls downwards the more the ?ngers will hold it. Therefore to take away a paper from underneath a ?nger you have to lift the ?nger by hand, or pull the paper away sidewards or upwards. It is important to know that the ?ngers are set away from the support, so that there is space provided for the paper, in case the paper is drawn uwpards. The object of my invention is to use the ec centric levers or ?ngers with the supporting 135 means at different points of the copyplate and that the ?ngers with their supporting means em body a new paperholding clip which opens by itself as soon as paper is pushed underneath the paperholding clip. 40 Now the operator can hold the paper with both hands and place it under the paperholding clip much better, quicker and more accurately. Having thus described my invention, what I claim and desire to secure by Letters Patent of 45 the United States is: 1. In a copyholder, a copy support, and means for holding a copy thereon, comprising paper holding clips and its mounting on the support, said paper holding clips being constructed in the form of a lever which has its turning point un 350 derneath the end of said lever which touches the copy or the copyplate and said turning point being at a certain distance away from the copy plate so that the copy can easily be pushed un derneath said lever, which being so constructed has an eccentric action whereby the copy holds tight on the copyplate and cannot be pulled downwards, but easily upwards and sidewards, said paper holding clips work under their own weight and are opened simply by pushing the copy underneath without being operated by 10 hand. '2. In a copyholder, a copysupport, and means for holding a copy thereon, comprising paper holding clips and its mounting on the support, said paperholding clips being constructed in the 15 form of eccentric levers which have the point touching the copyplate at a certain distance away from the copyplate so that the copy can easily be pushed underneath said levers but also at a certain distance away from its mounting so that 20 the copy can be drawn upwards as much as de sired. 3. In a copyholder, a copy support and means for holding a copy thereon, comprising paper holding clips and its mounting on the support, 25 said paperholding clips being constructed in the form of eccentric levers, which are continued in a horizontal part, this part being bent back wards again, so as to give additional weight to the eccentric lever. 4.. In a copyholder, a copy support and means for holding a copy thereon, comprising paper holding clips and its mounting on the support, said paperholding clips being constructed in the form of eccentric levers, which are continued in a horizontal part, this part being bent backwards again, so as to prevent the eccentric lever from falling forwards, at the same time giving addi tional weight to the eccentric lever. 5. In a copyholder, a copy support and means for holding a copy thereon, comprising paper holding clips and its mounting on the support, these supports being held in position by a ?at piece of metal on which ?at piece the supports slide in and outwards, these supports being pro vided with means to hold the paperholding clips with their eccentric action underneath and su?i ciently above the point where the paperholding clips touch the paper on the copyplate.
