United States Patent Machnacz [451 May 23, 1972 PAGE TURNER FOR SHEET MUSIC AND THE LIKE Joseph H. Machnacz, 12216 Aster Rd., Philadelphia, Pa. 19154 Filed: Sept. 3, 1970 Appl. No.: 69,213
References Cited UNITED STATES PATENTS Primary Examiner-Richard B. Wilkinson Assistant Examiner-Lawrence R. Franklin  ABSTRACT This invention consists of a rectangular board having a longitudinally disposed upturned lower edge to prevent the sheet of music or the like that is placed on the board from sliding off. Two diametrically opposed spring clips on the board hold the music in place. An electric motor is located on the upper right hand comer of the board, the motor being provided with a pulley that has an endless cord encompassing the same, the cord also encompasses a free-tuming pulley that is located on the opposite side of the board. A wire track is suitably mounted parallel to the just-mentioned cord. The purpose of the wire track is to provide a means of guiding a swivel fastener which is connected to the cord and also to a spring clip, the spring clip being secured to the sheet of music or page that is to be turned. A foot-operated switch, that is connected to an electric motor, completes the construction of this invention which is preferably mounted on a vertically disposed stand.
3 Claims, 2 Drawing Figures Patented May 23, 1972 INV ENTOR JOSEPH H. MACHNACZ PAGE TURNER FOR SHEET MUSIC AND THE LIKE This invention relates to page tumers which are devices used to turn the pages of a book or of music; more particularly to a page turner especially made for the purpose of turning pages of sheet music or the like.
It is the principal object of this invention to provide a page turner for sheet music and the like that can be operated by ones foot since it requires the use of both hands to play most musical instruments.
Another object of this invention is to provide a page turner for sheet music and the like that is mounted on a stand in front of the musician.
Still another object of this invention is to provide a page turner for sheet music and the like that embodies the combination of simple mechanical mechanism and an electric motor for the turning of the sheet music or the like.
With these objects already in view, other objects will no doubt appear hereinafter as the reading of this specification and its appended claims proceeds and the accompanying drawing is examined in connection therewith.
In the drawing:
FIG. 1 is a pictorial view of this invention in actual use.
FIG. 2 is an enlarged pictorial view of the major part of this invention.
FIG. 3 is an enlarged pictorial view of that detail of this invention that is enclosed within the arrowed ellipse and indicated by the number 3 in FIG. 2, although the hereinafter described electric motor is not shown for reasons of clarity.
FIG. 4 is an enlarged pictorial view of that detail of this invention that is enclosed within the arrowed ellipse and indicated by the number 4 in FIG. 2.
In the several views of the accompanying drawing, like parts of this invention are indicated by like reference numbers.
Looking first at FIG. 2 of the accompanying drawing it will be seen that this invention consists of a rectangular board 7 or the like on which sheet music or the like is placed. The lower longitudinal edge 8 of the aforesaid board 7 is upturned at right angle in order to prevent the sheet music or whatever else is placed on the board from falling off when the board is mounted at an angle on the top of the vertically disposed stand 9, as one can see by looking at FIG. 1 of the drawing.
Continued examination of the already-mentioned FIG. 2 of the drawing will show that the music 10 is held on the aforesaid board 7 by means of two opposed spring clips 11. A longitudinally disposed wire track 12 has integrally formed and vertically disposed wire legs 13 at each end thereof that are suitably secured to the top of the aforesaid board 7 above the upper edge of the sheet music 10. A spring music holding clip 14 is mounted on one end of a swivel fastener 15 that has its other end encompassing the aforesaid wire track 12. A portion of the aforesaid swivel fastener 15 is suitably secured to the cord 16 that encompasses the free-turning pulley 17. Freeturning pulley 17 is supported by the pulley holder 18 which is mounted on one end of the aforesaid board 7 between the upper edge of one page of the sheet music 10 and one of the aforesaid legs 13 of the wire track 12. The aforesaid cord 16 also encompasses the pulley 19 that is secured to the shaft 20 of the electric motor 21 that is also mounted on the aforesaid board 7 of this invention. The aforesaid electric motor 21 is connected by the electric cord 22 to a foot-operated switch 23, as one can see by looking at FIG. 1 of the accompanying drawing.
The way in which this novel invention works is obvious from examination of the drawing. It will be understood even by those not experienced in the art that when a sheet of music or a page of a book is placed on the aforesaid rectangular board 7 and held in place by the two aforesaid spring'clips 11, and a page of the music is to be turned by the holding clip 14, all one has to do, after plugging in the aforesaid electric motor 21 to a source of electricity, is to step down on the previously-mentioned foot-operated switch 23. Thiswill activate the motor 21 which will rotate the aforesaid pulley 19. When pulley 19 is rotated, the encompassing cord 16 will move automatically longitudinally In a counter-clockwise direction, as IS indicate by the arrowed line in FIG. 2 of the drawing. Since the swivel fastener 15, that has one end secured to the aforesaid spring holding clip 14, is secured to the cord 16 and guided by and stabilized by the longitudinally disposed wire track 12 that is parallel to the cord 16, the spring clip 14 will be moved over to the left side of the aforesaid board 7 and thus turn the page of music to that side of the board.
Obviously, many details not shown in the accompanying drawing can be added to this invention if it is so desired. For example, a simple device can be added to the left hand side of the board to automatically disconnect the aforesaid spring clip 14 from the music after the page has been turned. A second device can be added to the right hand side of the board to automatically cause the clip to grasp another page or sheet of music after the clip has been returned to the right hand side of the board 7 by the automatic reversing of the direction of rotation of the aforesaid electric motor 21. The board 7 can be equipped with an electric light for the reading of the music or book, if it is so desired.
This invention, whose construction and operation has now been described in detail, is subject to any and all changes and/or modifications that one may care to make in so long as the changes and/or modifications fall within the scope and intent of the appended claims.
What I now claim as new is:
1. A page turner for sheet music and the like, comprising a board on which sheet music is placed and secured, the board being substantially rectangular in shape and having a longitudinally disposed upturned lower edge, the said board being mounted on the upper end of a vertically disposed stand, electrically activated means for turning the sheet music or page when it is so desired, the said electrically activated means for turning the sheet music comprising an electric motor that is provided with a pulley which is encompassed in part by an endless cord that extends longitudinally to the other end of the said board where the cord encompasses in part a free-turning pulley that is supported by a pulley holder which is secured to the said board; and a spring clip adapted to be clipped to the sheet of music that is to be turned, the said clip being secured to one end of a swivel that is secured to the said cord.
2. The invention of claim 1, wherein the said swivel is guided by a wire track that is suitably secured to the said board parallel to the said endless cord.
3. The invention of claim 2, wherein the said electric motor is provided with a foot-operated switch for the control of the said motor.
