The ends of the arms of the book clamp extend below the pivots and are formed into The L-shaped,

handles and 85 as means for opening the book clamp.

An adjustable support shaft and a support stand are provided to hold the page turning apparatus and hold it in various positions as may be desired, comprising a shaft ID having a pivot hole formed in each end thereof. One end of the shaft ID is pivotally engaged between the arms 8 and 8 on the support brackets by means of a bolt H engaged in the pivot holes in the ends of arm' 8 and 8 and also in the pivot hole in the end of the shaft l B and a thumb nut [2 on the end of the bolt. A shaft having a pivot hole in the end thereof, is pivotally mounted on the lower end of shaft ID by means of a bolt 9| engaged in the pivot holes in the ends of the shafts and a thumb nut 92 on the end of the bolt. The lower end of the shaft 9i] telescopes into an upright tubular member 93 with a thumb screw 94 screwed in a threaded hole in the tubular member 93 near the top thereof and engaging against the shaft 90. The tubular member 93 is mounted in a horizontal base 95. Two foot members 95 and 96 are pivotally mounted on each end of the base member 95 by means of rivets 91 and 91, holes 98 and 98 being formed in the foot members as means for securing the foot members to the feet of a typewriter or for securing them to the desk by means of screws in the holes 98 and 98 and screwed into the desk.

A steady bracket clamp is provided to secure the base support of the page turning apparatus to the base of a typewriter frame, comprising an L- shaped member 99 having a lower horizontal arm secured to the base plate 95 by means of a screw I00. A hole is formed in the lower portion of the upright arm and a screw llll is loosely mounted in the hole. A small L-shaped member !02 having a threaded hole in the upright arm thereof is screwed on the end of the screw llll, the upright arm of the L-shap'ed member 99 engaging the outside of the rail 3 on the lower rear portion of the typewriter frame and the upright arm of the small L-shaped member I02 engaging the inside of the rail 3. When the screw I0! is tightened, it clamps the two upright arms against the rail 3 on the typewriter .fram e.

To operate the page turning copy holder the pivoted frame I! is tilted forward to the position shown by dotted lines in Figure 9, the lug I8 engaging against the arm I to hold the frame in proper position. Then the lever 85 on the book holder clamp 89 is pressed and the back or a portion of the note book is placed between the clamp and the copy support plate 4. The springs 84 and 84 hold the clamp against the book and keep it in proper position, the first page to be copied or transcribed being face forward in front of the copy support plate 4. The roller support frame I! is then lifted up and springs 42 and 42 hold the rubber rolls 40 in tension against the top part of the page to be transcribed. Then the knob 62 on the operating lever 60 of the remote control operating device is pressed. This pulls the rotatable clutch drum 3l' forward, the small rollers 32 frictionally engage the clutch drum to the clutch cam 28 secured on the roller shaft thus rotating the rubber rolls 45 forward and the friction of the rubber against the top page on the note book causes the page to slide upward. The distance the page is mioved at each stroke on the lever 60 and knob 62 may be regulated by adjusting the thumbscrew 61 on the operating device. When the end of the first page has passed under the rubber rolls the rubber rolls then engage against the top of the next page, thus all the remaining pages may be pulled through the page turning apparatus line by line or a number of lines at one stroke, and the pages of the book turned successively without removing the hand from the proper position on the keyboard of the typewriter, or similar machine.

When it is desired to inclose the copy holder in a desk with the typewriter, the page turning apparatus and the support shaft may be adjusted to the position shown by dotted lines in Figure 1.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing a from the principles of this invention, and I therefore do not propose to limit the patent granted hereon, otherwise than is necessitated by the prior art and the appended claims.
