W/LL/n H.PETERMAN BY 4d ATTORNEYS Patented Nov. 12, 1929 UNITED STATES PATENT OFFICE FRED HOSSELL, OF EBURNE, BRITISH COLUMBIA, CANADA, AND WILLIAM H. PETER- MAN, OF WACONIA', MINNESOTA PAGE-TURNING DEVICE Application filed March 8, 1928.

Our invention relates to improvements in page turning devices which are particularly adapted for use by musicians and others whose hands are occupied while they are required to continue reading from the pages of a book. The objects of the invention are to provide means whereby the development of air pressure by a foot operated cylinder pump or other suitable device can be employed for successively turning over the pages of a book as desired, and to provide a page turning movement which will be sufli ciently fast to turn the pages to suit the requirement of any musician and yet be so arranged that no damage will occur to the pages.

The invention consists of a plurality of vertical rods adapted to be interposed between the pages of a book and means for moving them one at a time to progressively turn the pages over and to hold them in turned position, as will be more fully described in the following specification and shown in the accompanying drawings, in which g The drawing is a general View of the invention.

The numeral 1 indicates the vertical members of a book rest or music stand at the upper end of which a rack generally indicated by the numeral 2 is supported. This rack preferably consists of a relatively broad strip of light sheet metal 3 forwardly bent at opposite extremities to form a pair of brackets 4 and 5 respectively. Extending from the bracket 5 is a horizontal cylinder 6 having an inlet tube 7 at one end and a cylinder head 8 at the other. The cylinder 6 is fitted with a piston having a tubular piston rod 9 which is slidably mounted upon a horizontal guide rod 10 secured at one end to the bracket 4. A spring 11 is fitted about the rod 10 which abuts the bracket 4 at one end and the end of the piston rod 9 at the other for the purpose of returning the piston and its rod to retracted or normal position, as shown. The end of the piston rod is fitted with a crosshead 12 which supports a latch rod 13 horizontally below the cylinder 6 having at its free end a Serial No. 260,169.

hingedly mounted latch generally indicated by the numeral 14. The latch is preferably formed of light sheet metal having a substantially spoon shaped forward portion 15, which is downwardly offset from the general plane of the latch and is'provided with a downwardly projecting finger 16 between the spoon shaped portion and the hinged connection. The outer extremity of this finger lies in a horizontal plane slightly above that of the spoon shaped portion, the purpose of which will hereinafter appear.

Extending between the brackets 4 and 5 immediately below the cylinder 6 is a slide bar 17 which is fitted with an adjustable stop collar 18. Slidably mounted upon the slide bar 17 is a plurality of collars 19 each of which is tapered at one end as at 20 and has a cylindrical rim 21 at the other, so that when two of the collars abut each other an annular face 22 is exposed between the cylindrical rim of one and the tapered end of the other. From each of the collars 19 an elongated finger 23 depends, which is adapted to be interposed to the rear of the page 24, which it is desired to turn. Connected to the inlet tube 7 of the cylinder 6 is a flexible tube 25 which extends to a bellows 26 or other suitable air compressor capable of being manipulated by foot pressure.

Having thus described the several parts of our invention we will now briefly explain its function.

The book is placed upon the rack 1 and the pages are turned over backwards one by one and a finger 23 laid upon each one of them, so that the last finger is finally covered by the first page to be turned in the right direction for continuous reading. When pressure is applied to the bellows 26 the piston rod 9 is thrust forwards, drawing the latch 14 along the upper edge of the collars 19 until the first one to be moved is reached, when the spoon shaped portion 15 will descend along the taper 20 of the collar 19, so that the finger 16 will be lowered into engagement with the exposed peripheral face 22 and will move it lengthwise of the slide bar 17 to the left, the finger 23 of said collar is moved in a like manner in a plane substantially parallel to that of the rack 1, thus moving the first page from its position at the right of the book to the left and exposing a new page to be read. The normal resistance to movement of each of the collars 19 is greater than: thatof the latch, which enables the latchto -be returned to normal position Without efi'ecting the position of the collar last moved by it. p I

It Will thus be seen that We-liavein vented a,

page turner Which is simple in form and effective in use and Which can be manufactured" and sold at a very loW figure.

hat We claim as our invention is:

1. A book page turningdevice comprising a: horizontally disposed cylinder having a piston and'pi'ston rod, means for imparting endwisc movement to the piston, a slide ba-r mounted parallel to the cylinder, a plurality of movable: collars upon the slide bar each having a depending finger, means actuated by movement of the piston in one direction for engaging and moving one of said collars along the'slide bar, and means for returning said collar movingmeans into position to engage-another collar.

2. A book paget-urningdevi'ce comprising a horizontally disposed cylinder having a piston and piston rod,-means" for imparting aoendwise movement to" the piston, a slide bar mounted-parallel to the cylinder, a series of collars'positioned upon the-slide bar each having'a depending finger, a latch carried by the piston and functioning on movement of the piston one direction to engage and-shift the endmostcoll'ar'of said" series along the slide bar.
