JOHN R. ELLIOTT, OF CAMDEN, NEW JERSEY.

BOOK-DISPLAY LEAF-TURNER.

Application filed March 13. 1998.

To all whom it mary concern:

Be it known that I, JOHN It. ELLio'rT, a citizen of the United States, residing in the city and county of Camden, State of New Jersey, have invented a new and useful Book-Display Leaf-Turner, of which the following is a specification.

The purpose of my invention is to heid books, pamphlets and other advertising matter and turn it over automatically.

A. further purpose of my invention is to retain sheets or the leaves of a book in strained position such is due to bending or gravity and gradually move tin` retaining device away from the sheets or leaves.

A further purpose of my invention is to operate the retaining mechanism for leaves under tension continuously by motor means, such as clock work, so as to release the leaves one aty a time.

It further consists of other novel features of construction, all as will be hereinafter fully set. forth.

Figure l represents a top plan view of a structure embodying my invention, parts being removed. Fig. 2 represents a broken side elevation of the structure of Eig. 1. F ig. 3 represents a top plan view of the form of invention which I have illustrated without the books. Fig. 4. represents the struw ture shown in Fig. l in end elevation, parts being shown in dotted lines. Fig. 5, is an elevation of a portion of the cloehF mechanism shown. Fig. 6 is a broken elevation of a stop made use of by me. Fig. T is a perspective view of one of the leaf-engaging fingers used in my mechanism. Fig. S represents a modification in broken side elevation. Fig. t) is a detail perspective view of the eseapement and stop mechanism.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings: I designates a frame or base of any suitable material, upon which I mount a motor Q of any desired form. In this particular instance I have selected clock work mechanism having frame 3, main shaft 4 and initial gear 5. I illustrate this conventionally, merely showing a train of gears to which I have applied reference numerals t, 7, S and il. without attempting to set out the exact train in detail as any suitable train of eloelc gearing will answer for this illustration. I have extended the end of the main shaft to sup- Speecation of Letters Patent.

Serial No. 420.812.

port a gear l0 and the shaft ll to support gear l), the gears 10 and 1Q performingl special. feeding function as hereinafter brought out. l malte use of any suitable hair spring 13 and eseapenient wheel and arm 13 and 18 to slow the Clock work me` elianially to a desired degree and to stop it when desired by engagement of a piu u ith the esoapeinent wheel.

The requirements of the mechanism which I have illustrated do not necessitate lunch movement of the clock-work and l have. therefore. made use of a winding lever Il. directly attaehable at any desired point to the shaft et, in order that the main spring il may be wound a porlion of a turn b v movement of the lever lst.

I have illustrated a bell 15 and elapper lll conveniently placed to be operated by lever 14 in its movement, in order to illustrate that alarm may be given when the ineeh.- anism reaches any suitable position as when it is sntiieientiv run down. to have released the leaves held, as hereinafter stated. or io require attention for any other reason.

I place books 1T and lo in proximity to the base and hold them in any suitahhl manner as by spring arms I9 and 20 upon extensions 21 and 22. held to the hase b r bolts and 2l, so that the bool; shall he retained with the ends nl' the pages parallel to the ends of my base l. The .sheets or the leaves of the book are then fiexed from the body of the book, presenting a portion as .shown so bent as to rest upon arms '2T and 28 and to he held against said arms hy means of the spring pressed lingers 2U and Btl, portions of whose surface, as at 31 and 32, are formed of ratchet eharaeter to engage with suitable gearing. In this case I cause these ratchet faces to be engaged by gears 10 and l2 so that the tingers will be fed in the proper direction by movement of the clock mechanism.

The arms 9.9 and il() are downwardly directed at the ends to engage with the parts 25 and 2G of the book by means of springs 33 and 34, which press the opposite en of these ngers upwardly at points beyond t the pivots provided for these fingers b v their engagement with the gears l() and 1Q. It will thus be seen that the fingers Qt) and 30 can he drawn to the position shown in Fig. 2 by winding the clock-work ineehant ism through movement of lever 1l in a ditl t) i il rection opposite to that of the arron and l that there will be a constant gradual inovel ment ot the lever 14 in the direction of the arrow, during the running of the clock with a retraction of the fingers in the direction of the arrows as shown and release ot' the l leaves as the lingers are Withdrawn from l contact therewith. This inward retraction i of the lingers results in the release of the l leaves a few, preferably one, at a time, with consequent closing ot' these leaves, presenty ing ditierent subjects matter to the view. i This continues until the clock-Work runs down or is stopped as by pin 38.

l recognize that. other motor mechanism than clock-work could be made use ot and that the retracting, retaining fingers may be variously formed to perform the functions required. I further recognize that the form of the base and support for the book may be conveniently varied with part of the advantage from my invention.

In the form shown in Fig. 8, I have illustrated the mechanism as applied to a stili? backed book. The mechanism is the same as that illustrated in my other figures except that vl have passed one cover of the book 35, between the spring 19 and the extension 21, retracting this spring 19 to position shown if desirable. The back 35 is thus clamped in eti'eet between the base and extension, and the cover Sti is held to the extension by any suitable means as by clamp 37. This retention of still covers of the book brings the book within the control of my operating mechanism so as to make it possible to operate the body ot the book in substantially the saine manner as a book with a flexible cover. It will be seen that clamp lf) may still be used tor the purpose illustrated in Fig. i?. notwithstanding that the still' covers ot' the book are held as in Fig. 8, the cover 351 in that case departing from the position illustrated and assuming a position at a slightangle to the extension 21 when the body oi the book is held as seen in Fig. 2, It will be evident that the structure shown may be used vertically, as in the illustration of Wall paper, maps and similar objects, one end only being made use of in such case.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is :n4

l. In a device of the character described, a continually n'iovable motor, retractable fingers moved longitudinally thereof by said motor, and means tor holding the fingers in Contact With the leaves.

In a device ot' the character described, a frame, a clamp retaining a book with its back toward said frame, a motor and a longitudinally movable linger controlled by said motor and engaging the leaves of the book.

3. In a device ot the character described, a trame, a motor thereon, a retaining clamp, a finger extending from said motor, a spring for causing pressure of the linger against the leaves and means for withdrawing the finger longitudinally from the leaves.

4.. In a device ol the character described, a frame, a clamp upon said frame, a motor, a finger movable longitudinally by movel ment ot' said motor and means for pressing the finger toward the trame.

5. In a device of the character described, a frame, a motor mounted upon said frame, controlling` mechanism for said motor, a linger, means for supporting a book and lncans for retractinp` said finger longitudinally from engaging said book.

G. In a book leaf' turner, a trame, a clamp for the book, a finger engaging the leaves of the book, and means for continuously and automatically moving the linger in the direction of its length.

7. In a device. ot the charaegter described, a traine. a clamp in ],iroxiinity to said frame. a finger, means for pressing the finger toward the frame, and means for causing movement of said finger in the direction of its length.
