This inventionrelates to a device for suppor-ting a stenographers notebook at the rear of a typewriter so that the operator can readilyiollow and transcribe the notes on the leaves of the notebook. I

More particularly, the present invention relates to a device of the above kind wherein manually operable vmeans is provided for elevating the leaves of the notebook-in a-step-by-step tashion so that the lines of notes may be most convenientl-y (followed as transcription proceeds, and

for turning the leaves as transcription of the lines of notes thereonis completed.

An important-object of thepresentinvention-is to provide a device of the above kind in which the leaf elevating and turning means is -conveniently operable at a ,point remote ,from the notebook and adjacent t'hekeyboard of the typewriter,

so that use of the device entails a minimum loss of time and effort on the .part of the operator of the typewriter.

Another object of the present invention is to provide an actuating means for the leaf elevating and turning device by means of which intermittent elevation of the leaves of the notebook may be conveniently effected for variable distances in accordance with the variable line spacing of notes as commonly taken on" a stenographer s notebook.

A further object is to provide a device of the above kind which will efiectively accommodate notebooks of various widths and lengths.

Still another object of the invention is to provide a device of the above kind which is com,- paratively simple and-compact in construction, highly efficient in use, andotherwise well adapted to meet with the requirements'for a successful commercial use.

ing the nuts M; The 11917650012 is adfiptd'to supported on th rest III, II by placing the book so that it is preferably hung over the upper edge of the plate III, a shown by dotted lines in Figure 4, the front cover of the notebook being disposed at the back of the plate [0, and the rear cover of the notebook being disposed flatly against the front face of the plate It], together with the leaves on which the notes to be transcribed have been written. In order to hold the leaves of the book even and to accommodate books of various widths, spaced guide strips l5 are provided on the front of the plate 10 near opposite side of the latter and in position to engage the side edges of the leaves of the book, said guide plates l5 being adjustable toward or away from each other. For effecting the latter adjustment, the guide plates l5 have rearwardly projecting bolts l6 that extend through transverse elongated slots I! in the plate l near the ends of said guide strips 1 5, nuts 13 being threaded on the rear projecting ends of the bolts 16. By tightening nuts IS, the guide strips I may be effectively secured in adjusted position. The plate I0 is further provided with a longitudinal elongated slot l9 intermediate the side edges thereof and in the lower portion of the same. Adjustable in the slot [9 i a bolt 20 having a nut 2| threaded on the forward projecting end thereof. By tightening the nut 21, the bolt 20 may b secured in any vertically adjusted position, and when so tightened, the nut 2| forms an abutment for the lower end edge of the rear cover of the notebook 50 that the latter is effectively sustained against lowering at the front of the plate Ill. The vertical adjustment of bolt 20 and nut 2| provides for the accommodation of notebooks of varying lengths.

J ournaled in the upper portion of the frame 6, I, 8, directly beneath the upper flange of the cross piec I, is a horizontal leaf elevating and turning roller 22 suitably constructed to have an effective friction surface and arranged to engage the front or foremost page of the notebook near the top of said page or leaf. The cut-out or notch 9 exposes the rear portion of roller 22 for effective engagement with the leaves of the notebook and provides clearance whereby the ends of the leaves may readily pass as they are elevated and turned rearwardly. This turning of the leaves is facilitated by means of an upwardly and rearwardly curved guide 23 mounted upon the cross piece I so as to positively direct the leaves rearwardly and prevent them from falling forwardly over the cross piece I. By adjustably tilting the book rest, its leaves may b maintained in frictional engagement with the roller 22, the upper end of the book rest being adjustable toward or from said roller 22. Further, in order to guard against upward slipping of the notebook at the front of the plate [0, the latter is preferably provided near its upper end with forwardly projecting inclined pins 24 arranged topenetrate the rear cover of the notebook and thereby aid in securing it against shifting relative to the plate I0. It will be apparent that by rotating the roller 22 in an anti-clockwise direction as viewed in Figure 4, the front leaf of the notebook may be elevated in a step-by-step fashion for any required distance to accord with the line spacing of the lines of notes on the notebook. Also, the line being read may be maintained directly below the roller 22 so that th latter will act as a guide to facilitate reading of the line. When the last line on the page has been transcribed, rotation of roller 22 will effect completion of elevation of the leaf and rearward turning thereof so that the next page of the notebook is exposed for use.

Thus far described, the construction of all illustrated forms of the invention is similar, and like elements of all forms are indicated by similar reference characters.

' The invention also provides manually operable means for turning the roller 22 so as to cause the step-by-step elevation of the leaves of the notebook and turning of such leaves. Such means for rotating roller 22 is operable at a point remote from said roller 22 and adjacent one side of the keyboard of the typewriter disposed on the base 5. In the embodiment of Figures 1 to 5, inclusive, the operating means for roller 22 consists of a flexible shaft 25 coupled at one end to an end of the shaft of roller 22 and extending through a tubular housing 26 which is also flexible. One end of tubular housing 26 is coupled at 21 to the adjacent frame member 6, the other end of housing 26 being fixed at 28 (see Fig. 5) in an opening of a vertical plate 29 secured to the rear face of the vertical flange of an angle bracket 30 whose lower horizontal flange is secured at 3| upon the forward portion of base plate 5 near one side of the latter. A spindle 32 is journaled in an opening 33 of the bracket 30 near its rear end, and said spindle is provided at its rear end with an enlarged circular head 34 rotatable in a circular recess 35 provided in the front face of the plate 29. The spindle 32 is secured on the adjacent projecting end of flexible shaft 25, and it will be apparent that it is journaled and held in position by the plate 29 and bracket 30. The forward end of spindle 32 is provided with a knurled knob 36 to facilitate manual turning of shaft 25 whenever this means is desired to be used for effecting rotation of roller 22. However, means is Drovided'for effecting step-by-step rotation of shaft 25 and similar rotation of roller 22 by reason thereof. For this purpose, a finger lever 31 is pivoted at one end upon the spindle 32 behind a ratchet wheel 38 secured on said spindle 32, the lever 31 and ratchet wheel 38 being mounted between the knob 36 and the bracket 30. Pivoted on lever 31 is a spring-pressed pawl 39 arranged to engage the teeth of ratchet wheel 38, and lever 31 is normally yieldingly elevated by means of a helical tension spring 40. It will thus be seen that upon depression of the finger lever 31 against the action of spring 40, pawl 39 will engage the teeth of ratchet wheel 38 and effect partial rotation thereof so as to correspondingly turn the shaft 25 and roller 22. This provides a means of variable line spacing in that it may be used to elevate the leaf of the notebook any desired distance, depending upon the stroke of the lever 31. As soon as the lever 31 is released, spring 40 returns it to elevated position and positions the pawl 39 for the next stroke. In order to properly limit the return stroke of pawl 39,a cam lug is provided at II on the front face of the bracket 30 and in the path of said pawl so that said pawl will be automatically disengaged from the teeth of ratchet wheel 33 when it has reached its limit of return movement under the influence of spring 40. Accidental retrograde turning of ratchet wheel 38 and shaft 25 is prevented by a suitable spring detent 42 mounted on bracket 30 and engaging the teeth of ratchet wheel 38. As the lever 31 is located at one side of the typewriter keyboard, it can be conveniently and quickly reached and operated so as to "fiect turning-6f tl'ie roller 22 with a' m inimum "lessortimeand"expenditure of effort. In tials Embodiment, "it has been 'found that a SIig-Iit amount of 'lo'st m'otion Will-behad "due 'to the use of the flexible shaft 15, and this lost motion would ordinarily permit creeping or slight retrograde 5 turning of 'roller 22 after being actuated. As thiswould allow slightobj ectionabl'e shifting of "the notebook-leaf after being elevated -to the desired degree, it is prevented by -means of a "spring preSsed detent *43 'mounted "on a frame member B and engaging the teeth "of a ratchet -wheel 44 fixed on "the shaft of roller 22 at "one end of the latter.

In" the [embodiment of Figures -6 to* 8,'-"inc1u- "sivef'the shaft of roller 22has a "bevel gear: 45

"noted "o'non'e 'end thereof and 'me'shing 'with' an- I other gear 46 "fixed on the upperend er sin '11 journaled at one side of the frame 6, 138,

in brackets "48 "secured "to the adjacent -f'rame "memberifi. The lowerend of the shaft-Mis re- "ceived in a thrust bearing -49 'mounted on *the base plate ""5, and a further-gear "50 is-secured onthe'iower portion of shaft 41 and meshes with another gear "5! fixed on the'rear-en'd or a hori- "zo'ntal forwardly extending operating-shaftfl "journaled adjacent but above 'thebase plate 5 "along one side 'of'the latter. The'fo'rward 'n'd of"shaft52' isjournaled in and projects-forward- "1'y"through "an anglebracket "53 secured on base plate "'5, and the forward terminal of shaft "52 has a"knob"54'secured thereon. Pivotedat one end on' the shaft 52, between the knob/ 54 and b'racket 53 is afinge'r lever'55 having'a'spring- .jpressed "pawl '56 hinged thereto and "arranged "to engage the teeth'of' a ratchet'wheel 51 secured on .fshaft 52 between lever'55 'and bracket 53. FA helical tension Spring '58 acts to swing 'the finger lever-'55 in one direction so as to'position pawl 56 for engagement with theteeth of ratchet wheel '51 on the next operative "strokeof the hnger 1ever55, the return movementof the'jpawl "56 resulting in its engagement with a 'cam lug 59 by means of which it is disengaged from the "teeth of ratchet'wheel 151 so as to 'limit"thereturn strokeof said lever. Accidental'retrogra'de turning ofshaft 52 and ratchet "wheel 5'! is'prevented by means of a spring detent'fifl 'fi'xed'onthe 'bracket' 53'and engaging the teeth oi'iratchet wheel51. It will be seen that upon swinging the 'lever'55' to the. right in' 'FigureB, the shaft SZ'may -be partially rotated for 'similarly'turning roller int-and efiecting the step-by-step elevation of 'thenotebook leaf. Also, spring58acts tore:

turn thellever and its pawl to the position'for thenextstroke. of lever 55. Lever'55 islocated beside the keyboard of the typewriter whenthe latter is placed on the base plate 5 so that step- -by-step rotation of roller 22 may be conveniently effected with a minimum expenditure of time and effort. At the same time, when a great devgreetoffielevation of the notebook page is de- --sire'd,-knob 54 may be utilized. By this use of rigid shafts and. gears, use ofthe detent 43 and ratchet wheel .44 .of Figure 1 is not necessary.

"In the embodiment of Figures 9 and'IO, a'projecting end of the shaft of roller '22 has, a ratchet wheel 6i secured thereon, and "pivoted on said shaft inwardly of the ratchet wheelfil is one end fa lever 62 having a pawl 63 pivoted'thereto and arranged to engage the teeth ofithe ratchet -tvheeF'Bl.
