This invention relates to note book holding devices, andmore particularly refers to devices, suitable fobholding short-hand note books orsimilarcopy, used in connection with 5 typewriting machines.

, The main object of this invention is to provide adevice of the character stated, having novel and improved means for feeding the sheets of the note book as used, the action of said feeding means being more positive and reliable than that obtainable by otherdevices heretofore in use.

Another objectof this invention is to provide a copy holder, particularly adapted for use in connection with short-hand note books, composed of members telescoping one within the other, and affording a collapsible,yet rigid support for the note book, adapted to be permanently installed at the rear of a-type- 2O writer, even if the typewriter is mounted on a drop type desk. v

A further object is to provide a copyholder the construction of which is such as to permit reary insertion and removal of a note book i such as used by typists'for taking short-hand notes, Without impairing the rigidity of the holder itsnr; f V

A still further object is to provide novel and improved means for mounting the short so hand book, for the purpose of inserting it in the note book holder so as to be securely held in the proper position for the gradual feeding of its sheets on the part ofthe operator.

With these and other objects in view, as will more clearly appear as the description pro- 3 with another device of a similar character,

forming the object of a co-pending application for ,patent entitled book supporting device, filed by me June 30, 1922, Serial No. 571,91e. f

11 said application I have described a device intended for practically the same purpose, embodying a number of features which in practice I have found tobe susceptible of further improvement; and these improvenents, which are mostly directed towards rendering the operation'of the device more positive and reliable, and partly towards increasing the strength and rigidity/0f the device, have been embodied in the present invention, and co-operate with each other in greatly improving the performance of the device as a whole, and in extending the field of its applications;

In order to facilitate understanding of the novel feature mentioned, I shall. proceed with the description of the device illustrated in the annexed drawings, and shall particularly point out their advantages as the several pointswill be reached in the course of the description. V

The drawings illustratethe preferred embodiment of my invention, as used in connection with ordinary shorthand note books; however, the said drawings must be 'considcred as being intended for illustrative purposes only, and not in a limiting sense, beause many of the details of construction may vary from those shown; and also because, although the deviceillustrated is particularly suitable for use in connection with stenovice in its extended position, at the rear of a'typewriting machine;

Fig. 12 is a plan view of the device in its closed position; and

Fig. 13 is a fragmentary plan view of the same, with the casing in which the operating mechanism is mounted, thrown open for the insertion or removal of a note book.

The general appearance of my device in its preferred form, is illustrated in Figs. 1 to 4, and from these it may be observed that the same consists, essentially, of two main parts: a stand, 20, suitably mounted on a l ase plate .21 and secured thereto by means of an inclined brace 22, and a book holding member 23 slidably mounted on said stand so as to form a telescopic structure adapted to be maintained in its extended position, as shown in Fig. 1, or adapted to be caused to assume the inoperative or retracted position shown in Fig. 4, where one of the said parts overlaps the other.

One of the main objects of my invention, is to provide a notebook supporting device, carrying an operating mechanism for turning the leaves of the book, adapted to hold the book from which notes have to be transscriped, in full view of the operator, facing the operator directly, and at a distance calcln lated to suit an operator of normal vision, without causing eye str in. These conditions are of course aimed at, as the ones best insuring rapid and efficient transcription, and the same time inducing the least strain on the the operator. Practical considerations also make it desirable for the device to be so constructed, as to be readily applied in connection with any type or make of typewrit ing machine, its setting up being practically inldfependent of the typewriting machine itse I have therefore adopted the simple arran gement shown in the drawings, where the stand on which the device is supported is mounted on a base plate 21, made of sheet netal, and adapted to be placed with its forward portion 24 (Figs. l and 5) directly underneath the rear feet of the typewriting machine 25. In this manner, the device may be placed directly behind the typewriter, thus remaining at a convenient distance from the operators eyes, and it may be held in this position by the weight of the typewriter; there being no necessity of using any other fastenmg means.

This is important, both on account of the avoidance of the use of screws or other fastening means which would be apt to mar the desk on which the device is placed, and 011 account of the ease with which the device may be placed in position or removed, in a few seconds. Furthermore, the very simplicity of this arrangement, is a contributing factor decreasing the cost of production.

A device intended for use in connection with a typewriter placed on top of a table or desk having a stationary surface, does not necessarily have to be of a collapsible construction; since when the device is in use, the book mounted thereon must be in full View of the operator, looking over and beyond the typewriter, as is shown in Fig. 1. However, typewriting machines are very often mounted on desks of the drop table type, where the machine may be caused to disappear under a movable portion of the desk top, when not in use, so as to permit the use of the desk unencumbered by the machine.

This type of desk, which is represented in Fig. 6, comprises a movable table 26, on which the typewriter 25 is mounted, pivotally mounted at the sides at 27, and operated by the raising or lowering of the movable desk top portion 28, in a well known manner. The figure represents the desk in the act of being closed, and from the same it may be seen that the movable top portion 28 passes fairly close to the upper part of the typewriter, so that it would be utterly impossible to close the desk, were the book-holding device held at the rear of the typewriter in its extended position.

For this reason, I prefer to make my device in two parts, one movable in relation to the other, and adapted to be set in such a position, when inoperative, that the operation of a drop type desk will not be interfered with.

In my co-pending patent application abeveareferred to, I have taken care of this requirement, by pivotally mounting the book-supporting member on a horizontal pivot at the top of the stand; this permitting to set the upper, or book-supporting member, in a downward, or folded position, over the top of the typewriting machine. Further experience, however, has led me to believe the telescoping construction shown in the present drawings, to be preferable, being less apt to interfere with the-typewriter, and being simpler and easier to operate.

In said Fig. my device is shown mounted; in position at 29, at the rear of the typewriter, in its retracted position, allowing free operation of the desk, as illustrated.

The collapsible construction of the device is obtained, as stated, by causing'one of its main parts to telescopewithin the other. In the present case, thelower member, or stand 20, is made in the form of plate embossed with'a shallow C section, best seen in" Fig. 5, provided with two outwardly directed longitudinal flanges- 30, The upper, or book-holding member, comprises a plate 23, the edges of which are bent rearwardly and inwardly at 32, 33, to slidably interlock with flanges 80, 31, respectively, so that a telescope ing connection becomes established.

Plate 23 is reinforced at the rear longitudinal" bars by two 0.1:,06, project ng within the shallow deprd- .non of the Cshaped part 20. At the ,rear of said part 20, is mounted a spring controlled shaft36,-carrying two step lugs 37, 38,.tending to remain-inthe position shown in Fig. 3," so tlnit-when' the book-holding member is in its r and position, thelower edge of bars 34, 55, rests against the said stoolugs, and the devicermains set in its extended position,

Shaft 36 is integral or provided with a hand control lever 39, by means of which the shaft may be rocked ina clockwisedirection. By so operating the shaft,,sto-p lugs 37, 38, will move away from bars 34, 35, and the book-holdingmember will become free to fall to its lower position, shownjin 1:, by the action of its own-weight. Impact rcceiving means are preferably provided, to prevent unnecessary noise, era too'violent shock, when the book-holding member strikes bottom; and a simgle contriyance to thisend is shown in F 2 in the form of bow spring 40 attached at ll to plate 21, directly ufnderneath thebook-holding member, acting as a bumper absorbing the impact thereof.

A. note-book 42 is N ly mounted on the book-holding member, as v ill be later specilied, and set in operative position with respect to the operating meohanisnr This con' sists, essentiall of arotatable shaft 43, mounted across the top and in frontof the exposed page 44; of the book provided with one or more circular contact members 45,

held with suitable pressurefabutting a ainst" the surface of said NEWS; andan o aerating mechanism controlling theoperation of said shaft. The relative positions of-theseparts is shown in Fig. 10, where it 1s seen that rotation of shaft 43 in a cloc wise direction causes the outer leaf 4 against which members 45 abut, to move upwardly and fall over theback of the device, thus exposing the next sheet 46 to VlGW. L a

y In the device forming the object of my copending application abovereferred to, the contact member causing the. gradual ant successive feeding of the sheets or leaves of the note-book, is a rubber apron or belt, the motion of which is translatory rather than circular; but the character ofthe feeding means employed, is not to be limited to any particular type, since feeding means of va rious designs will answer; also, it may be here noted,the idea of feeding a sheet of paper by means of a rolling ortraveling friction. member, is, broadly speaking, not new. i i

The feature which is new, and important, in the, arrangement adopted, is a way of mountingthe feeding member insuring at all times a positive feed, in connection with a note-book of the character specified.

F or a device of this character to be practical,ir is necessary that all parts of a page become gradually exposed to View; therefore it is necessary, for the operating mechanism, to c'oncealas little as possible of the page I underneath, so thatthe writing space may be utilized. to best advantage. For this reason, the line of contact between the feeding member and'the underlying leaf, is caused to be quite at the top of the page, as shown, so that possibly only one or two lines at most of writing space at the top of, the page will be left blank when taking notes.

However, ordinary, stenographefis notebooks, consist of quite'a number of sheets folded together in;a single fold, so that the pages at the midde of the book start at a point about one-quarter ,of an inch lower than the outer pages, or even more. As page after page is turned over, the thickness of the book decreases, and since the feeding member must be maintained inconstant contact therewith,

it follows hat the feeding member must be made movable towards the book, that is, the contact must be maintained while the thicl ness of the book decreases. This may be assured in a number of ways, for instance by employing resilient means for creating the pressure necessary to create the necessary frictional contact. If the feeding members position in relation-to the underlying book, at the beginningof the operation, is such that the line of contact, is about three-eights of an inch from thetop of the'page, as shown in F i l, and if in order to take up the difigradually occurring in the thickness of the book, the feeding member is caused to travel right across in a transversal direc tion, when the middle of the book is reached,

the feeding member is quite likely to abut the sheet, which is substantially, or actually out of contact with the feeding member.

In the device described in my co-pending application above-referred to, the shaft of the feeding member is carried by a frame which is pivotally mounted to allow movement of the shaft from front to rear; but said frame is pivoted at a point above the shaft, and forward, so that when the shaft moves against the book, it gradually assumes higher and higher positions. I have found this to be a very serious drawback to the efficient operation of the device, inasmuch as this feature still further accentuates the tendency of the line of contact to gradually move to a point above the binding line, which I have just mentioned.

It is therefore important, that the feeding member be mounted in a way which will assure the line of contact with the underlying sheet, being permanently below the folding or binding line, so that the feeding of the sheets may proceed in a continuous and regular manner, from beginning to end.

This end may be achieved in a number of ways; but since the pivotal mounting of the frame carrying the feeding member offers a simple and convenient means of producing the desired result, I prefer to retain it in the present device, but in a suitably modified form.

Accordingly, shaft 43 is mounted in a frame 47, which is pivotally mounted at 48, at a point above the book at the rear; so that as the thickness of the book decreases, the feeding member moves along a downwardly directedv arc, and will cause the contact line to always remain past the binding point of any given sheet. To assist in the folding back of the sheets, as they are gradually fed upwardly by the feeding member, the frame is preferably formed with a curved upwardly inclined front surface i9, gradually forcing the sheets towards the rear of the device, un til free to fall back due to their own elasticity and weight. ihis action of surface 49 will become apparent by observing the outline of sheet 14 in F 10.

ihe movement of the feeding member is always eilectcd in the same direction, and its travel, and the extent thereof, each time that a. portion of a sheet is caused to move upwardly, are preferably controlled by the operator, to suit hi or her convenience. Therefore I provide a key operated controlling mechanism, and means for adjusting the range of its operation, the main objects in view being convenience of operation, and simplicity of design.

At this point also it may be stated that motion of the feeding member in one direction may be produced in a number of ways, as any competent mechanic well knows; by means of a controlling member actuated always in the same direction, or by means of a member movable in two opposite directions; or by any suitable mechanical expedient or means.

Together with a mechanical arrangement which I have selected on account of its simplicity, and which is admittedly susceptible of change in various directions, I have incorporated some features which I consider important apart from. the mechanism itself, and which I consider to be new and integral part of this invention.

One of these features concerns the manner of controlling the operation of the device. In devices of this character, a key lever is ordinarily employed, pivoted on a horizontally crosswise pivot, and operated by striking the key downwardly.

A key lever of this description is shown, for instance, in the drawings appertaining to my copending application, and while its operation is fairly satisfactory, I have found that the speed of the operator could be improved by adopting the form of control shown in connection with the present device.

By referring to Figs. 2, 4, 5, it will be observed that this arrangement compriscs a horizontal shaft 50 mounted from front to rear alongside of the typewriting machine, carrying a hand control lever 51 mounted at its front end, upwardly directed at one side of the typewriters keyboard. The operator strikes this lever from time to time with the side of the hand, forcing the same outwardly, and therefore causing angular motion of the shaft. At the other end of the shaft, suitable means are provided for transmitting this motion to the operating mechanism, as I will later describe, and spring means are also provided for returning the shaft and lever to their normal position.

In this manner, the operator is sure to strike the lever every time, simply by an extra side movement of the hand, entailing no necessity whatever of aiming at any particu' lar point, or of exerting any special amount of attention; so that his or her attention remains concentrated upon the reading of the notes, and the operating of the typewriter in the usual manner;

The extent of the motion of the feeding member, to which the movement of shaft 50 is ultimately transmitted, is determined by the extent of the angular motion of said shaft; therefore, by regulating the angular travel of the shaft, the amount of paper fed at each stroke is accordingly regulated.

I provide therefore adjusting means of any suitable character, permitting lever 51 to move more or less, and a suitable arrangement to this end is illustrated in Figs. 2', 4:, 5. In the same it is seen that shaft 50 carries a cross arm 52, provided with an adjustable screw 53, which strikes the surface of plate 21 when lever 51 is moved outwardly. By causing the stem of said screw to project more or less from the cross arm, therefore,

ferred to I have described an arrangement embodying such a feature.

Upon further experience, however, I have found that this means of creating the necessary pressure, is apt to be not entirely satisfactory at all stages of the operation, unless fect of the variations gradually taking place in the thickness of that part of the note-book against which the feeding member abuts. Such variations will naturally be reflected by variations in the pressure exerted by the spring "or other means used, which may be suitable when a new book is inserted on the boolcholder, but may become inadequate as between the exposed sheet and one or more of the underlying'sheets, which may cause the outer sheet to pull up one or more of the underlying sheets at one time.

Now, it is obvious that the pressure must at times be sufficient to feed the outer sheet as the operator requires it; at the same time, said pressure must never be such as to I cause the feeding of morethan one sheet at a time. It would not be quite exact to state that the pressure shouldbe uniform at all times, because in fact more pressure is required for turning the pages as the book decreases in thickness, than is required at the be ning; but neither is it necessary to maintain the pressure exactly at a given figure for each stage of the operation. there being naturally a certain leeway which may be taken advantage of'in designing the device. In a general way it may be stated, that while it is desirable to cause the pressure to increase as the thickness oft-the book'decreases, yet it is not strictly necessary to do so; it is suflicient that the pressure exerted be at all times sufficient to feed the sheets offer ing the most resistance, in a reliable and continuous manner. If the pressure is limited to this requirement, it is not liable to be execssure in an OlOJGCtlOHZllJlG sense, when feeding,

the outer sheets. a

In the construction shown in the draw in which I will presently explain, the pressure created does not even increase with the decreasing of the thickness; on the con trary, it decreases, the design of the arrangement having been influencedby other cons d crations. But in practice the result'remains that the pressure obtained is sufiicientto op crate the last pages ofthe book; itis perhaps a trifle excessive when the first few pages of the book are unfolded; but it is never objectionable in the sense of causing the feeding of more than one sheet at a time; i

I attribute this result to the fact that while i V a spring is used, indirectly, to maintain the' feeding member in contact with the underly} i. ing sheet, yet the actual frictional contact enmeans are provided to counterbalance the ef-' abling the feeding member to was smit its motion to the sheet, is independent of, said spring, and is caused by aforce which is practically uniform throughout, such as might be caused by a vertically movable counterweight.

Such force is exerted pulling action of the flexible element, which is transmitted to the feeding member in.

such a way as to first cause a tendency in said feeding member to press against the under-' lying page, and then to operate the feeding member when the resistance to this fractional; transitory motion becomes sufficient to cause its termination. A double action is therefore performed by the force originally exerted by the operator, in first creating the necessary frictional contact, and then causing the feeding action to take place.

This result may be attained in Various ways, but in a general sense it maybe stated that it will follow a construction where the feeding member is mounted on a frame which is movable in relation to a point of support, and where the actuating force is appliedito the feeding member in such a way as to'tend to move the frame in the direction ofthe sheet to be fed, owing to the reaction induced in its point'of support; g

One of the embodiments of this principle is shown in the drawings, and. may be observed by referring to Fig. 11. On account of considerations which I will point out at a later stage of this description, I preferqto use a pawl and ratchet mechanism for producing the rotation of the feeding member. As

directly owing to the" previously explained, the feedingmember comprises a shaft 43, which is' rotatably J mounted on a frame 47, which' is in its turn pivotally mounted at 4.8 to the book holding The natural tendency offthe frame member.

is to move downwardly, holding the feeding a member against the surface of theunderly ng sheet 44.

At one end of shaft 43,externally to frame 47, is mounted 'a pinion 59, in mesh with a gear 60, loosely mounted on a stud 61 attached to said frame. Alongside said gear, on the same stud 61, is also rotatably mounted a drum 56, to which, as we have seen, the end of flexible element 54 is attached. Said drum has a hollow, within which is placed a helical spring 62, having one of its ends secured to stud 61 and the other to the peripheral surface of the hollow in said drum, said spring tending to cause rotation of said drum in a clockwise direction.

Said drum carries a pawl 63, engaging the teeth of gear 60 when said drum is caused to rotate in a counter-clockwise direction,

but allowing the free rotation of said drum in relation to said gear, when the drum is retating in a clockwise direction. Said pawl is maintained against the surface of the gear by a leaf spring 64.

A pull exerted on wire 54, obviously causes rotation of drum 56 in a countercloclnvise direction, and this in its turn causes rotation of gear 60, and consequently rotation of pinion 59, shaft 43 and feeding member 45, in a clockwise direction. Rotation of inc .1- ber 45 in this direction, causes the feeding of the sheets, as previously explained.

However, it will be observed that stud 61 is eccentric to pivot 18. Any downwardly directed force applied to stud 61 will cause a turning moment of the frame around its pivot, causing the feeding member to press against theunderlying surface.

It therefore can be seen, that a pull. exerted on wire 5% in a downward direction, such as takes place upon the operation of lever 51, will create a tendency in frame 47 to rotate in a clockwise direction, since said pull may be considered the equivalent of a downwardly directed force applied against stud 61 through the intermediary of drum 56.

The desired condition of creating the necessary frictional contact, and producing the feeding action by means of the same force, is therefore realized by this comparatively simple arrangement. As stated before, the pressure exerted by the feeding member against the underlying surface decreases as the thickness of the book decreases, because the leverage of the pulling force becomes gradually smaller in relation to pivot 4-8; however, the difference between the two extreme positions of the feeding member due to the thickness of the book, is comparatively small, and does not influence the pressure exerted to any great extent. On the other hand, proper location of stud 61 in relation to pivot 48, will determinethe amount of average pressure produced, and experience will furnish indications as to the best horizontal distance or leverage between 61 and 48, to be adopted in practice.

We have thus created a condition where a practically uniform pressure created against the pages of the book by the feeding member, as the feeding takes place, this pressure being, owing to the leverage adopted, the one best suited to produce a sufficient but not excessive frictional contact; in other words we have created a condition close y resembling the feeding by hand, where the thumb is first pressed against the surface of the sheet, and is then moved in the feeding direction, while the pressure is maintained.

The construction indicated, while not realizing a condition where the pressure is increased rather than decreased with the decreasing of the thickness of the book, is preferable for reasons of design, so as to preserve the compactness and small size of the device. It will he observed that if the combined weight of frame 47 and the feeding member carried thereby is suflicient to create the desired friction between the rollers and the underlying sheet, it may be unneeessary to add to this action the pressure exerted by the pull of the flexible element; therefore, in this case, the direction of application of the pulling force may be substantially in line with the pivot upon'which frame 47 is mounted so as not to noticeably affect the pressure exerted by the pivotally mounted structure upon the sheet. Also in this case, while an auxiliary spring might also be employed, a fairly uniform pressure is obtained in an exceedingly simple manner.

The drawings also illustrate a very convenieuz' manner of transmitting the motion of shaft 50 to the operating mechanism. Independently of the mannerin which the feeding of the paper is effected, it is obvious that the connection between the shaft and the operating mechanism" must be such as to allow the motion of the book holder relative to its stand, without hindrance, and without entailing the necessity of additional operations.

This applies whether the book-holding: member is mounted to the stand by articulated connection, as shown in my (Jo-pending application, or whether the connection is by telescoping arrangement, as in the present case. For the sake of SlITIPliClty, I profor to use a. flexible elen'ient controlled by shaft 50, and exerting a pull on the actuator of the operating mechanism when lover Si is moved outwardly.

This flexible element, designated by numeral 54, is attached to-a love integral with, or attached to shaft 50, at the rear, and participating of the angular motion of the shaft. Thus outward movement of love I?! is transformed into a pullexerted on flexible element by lever said pull. being in its turn transmitted to drum 56, to which the other end of flexible element is attached. through the intermediary of an idle pulley 57, over which element 54 is caused to pass.

-Tlll 3i(ll)l8 eloinentmust he inortensible' as well as flexihle, and must have a high ten sile resistance, in order to'p'rovide continuo'us and reliable service; and for this purpose I prefer to use cat gut, such as usedfor musical strings, although metallic wire would also answer. However, it is necessary to pre vent th possibility of the wire becoming entangled, or bent, or damaged, so as to preserve its flexibility, and so-that the :device may be operated at all times without delay. The new feature above referred to is intended to take care of these conditions, and cons sts in applying a flexible sheath 58, en closino; the flexible element from one endto the other, guiding it all through. This flexible sheath is preferably made of spring wire closely wound, to produce a she i or conduit whic. is extremely flexible, and. at the same time is elastic, easily bent around, but constantl tending to resume its naturally straight condition when the opportunity is given. r V v Qu account of its function, flexible sheath .fiSactually constitutes a connection between the lower part of the stand, and the upper part of the book-holding member running alongside of the device,,as 1, 2, clearly show; and on account of its flexible nature,

- .when the book-holding member is released,

from catches 37, 38 by the action of control lever 39, this member can instantly fall to its inoperative position, shown in Fig. l,

sheath 58 forming into ,an. easy curved, shown, .WlilllOUli any sharp bends. As part 23 is again raised to its operative position, sheath 58 resumes its straight condition of its own accord, without showing the least permanent deformation.

Sheath 58 is therefore a protective mem her for the flexiblewire, which maintains it at all times free of entanglements .or sharp bends, which insures its free andeasy operation by guiding it throughout its length,

3 and which adds to the appearance of the machine, at the same time causing no hindrance to its operation.

An important detail in the operation of the device, is the insertion andthe removal of a note book, which must easily and readily be made. Also, it is important to design the device, and the means for holding the book in place, in a manner calculated to insure positive action at alltimes, and a firm hold on the book itself.

These details aresubstantially the same as those shown in myprevious patent applica The operatmg mechanism, and frame ti on. 4-7, a re i'nouuted in a casing 65, which is pivptallv mounted atone side of part 23,, by means of a hinge member 66, having a longitudinal pivot 67 Said hinge is-preferably of the spring type,being provided with a spiral spring 68, tending to maintain the casing in its open position, shown in Figs. 8, 13.

At the other side, the casing may be secured in position byaspring catch 69 engaging a pin 70. By pressing catch 69, the casing'will be thrown open, and. the entire surface of book-holder 23' will become exposed and acccssible. Saidpart 23-has its lower edge upturned at 71, to provide a support for the book carrier 7 2, to which the book is attached ina suitable manner, i

A short pin 7 3 preferably is provided, projecting from the surface of part 23, engaging a corresponding opening in the book *arrier or plate72. (not shown). being in its open position, the book-carrier,

together with its attached book, is placed with its lower edge upon support 71, and is then swung against the surface ofpartQS, in the manner illustrated in Fig. 8; casing is then closed, andthe device is ready for opera-- tion. The object of pin 73 is to engage the plate 7 2 so as to prevent its upward shifting due to the force exerted against the book by the. feeding member. i

hen part 23 isin its lower, or inoperative position, the book carried thereby is concealed from view, and it is necessary, in order to start transcribing, to raise part 23. Its upper edge is therefore turned rearwardly as at 74, forming a recesswithin which the tip of the fingers of the operator may be inserted to takehold ofand to lift said part 23.

7 At the same time, said upper edge forms a curved support for the the book, 75, I

The bookis secured on to the plateor carrier 7 2 in any suitable manner; however, I prefer to adopt the arrangement shown in Fig, 7, where it appears that a note book 7 6, provided with binding clips 7 7 formed with a loop or eye 78, is used. Said loop or eye overturned leaves of portion, which is transversal to the face of thebook after the fashion of an ordinary hinge. Thebook remains thus suspended to the book carrier, said book carrier in its turn. providing a metal to metal connection with the device. 1 The book may be left connected to the book carrier while notes are being written, since the book carrier provides .a

stiff backing which greatly facilitates proper holding of the book.

To. further" facilitate the insertion of the book carrier in position, the sides of part 23 are formed withgforwardly extending lugs 82, guiding the plate, 7 2, when the book carrier is set up as shown in Fig. 8.

The bookis held in positionby the pres- Casing 65 sure exerted against'it by the feeding member; this pressure being derived, indirectly, from thetcnsion of spring 62, tending to wind up element 54 on drum 56. Furthermore, its leaves are prevented from fluttering, so that its front page is held flat and exposed to view, by a spring cross bar 83, pivotally attached to the sides of casing by arms SI, and held pressed against the face of the book by a spring 85.

In its standard form, the device is held in position simply by inserting its base plate 21 under the feet of the typewriting machine; but it is obvious, that the device may be made, if desired, adapted for direct attachment to the frame of the typewriter itself, or else it may be made adapted to be supported on the desk in some other manner.

In my co-pending application No. 571,914, I have pointed out the fact that in operating this type of devices, it is desirable to feed a few lines at a time, and even half page at a time, leaving the copy stationary while the portion thus exposed is being transcribed. I have also explained how, on account of the relatively long feed required, if a circular feeding member of a small diameter is employed, it becomes necessary to so control the feeding member that a relatively short angular motion of the operating lever, is transformed into a relatively large angular motion of the feeding member, which might even have to rotate one or more revolutions.

This is the reason which has led me also in this case to use power transmitting means calculated to provide the necessary ratio between the first and the ultimate movers although it is obvious that also in this respect my device is susceptible of change in a number of ways.

The feeding member comprises, as stated, a shaft 43 carrying the contact member or members. In order to obtain a light construction, and at the same time good fricsaid shaft.

tional contact and positive action, I prefer to use the construction shown, where a plurality of disc shaped members, designated by numerals 45, 45, 45", 45, are mounted on Said disc shaped members are preferably made of rubber, or with a rubber periphcrical section, and are formed with notches 87 causing their periphery to acquire an outline similar to that of a gear, composed of a number of radial prongs 88. The broken out line thus obtained, produces a yielding surface permitting to two or more of the prongs to engage the underlying surface at one time, and a good frictional contact becomes thus established.

In the foregoing description I have clearly set forth the construction and operation of my device; and in so doing I have endeavored to analyze the purpose of the various elements involved, rather than their specific form, being aware that similar functions may be fulfilled by mechanical elements differently constructed and arranged. While the drawings represent the prefered embodiment of my invention, therefore, the same will have to be considered as intended for illustrative purposes only, and not in a limiting sense.

It is accordingly my intention to carry my invention into practice in any way or manner which considerations of design or manufacture may suggest, and which may enter, fairly, into the scope of the appended claims.
