Application filed Got'oberl 21, 1920. Serial No. L118,387.

To all w /tom t may concernv Be it known that I, Fnnonnrc'n Civil., of

l2 IVillisden road, Epsom, Auckland, in the Provincial District or' Auckland, in the Dominion of New Zealand, a subjectof the `King oi Great Britain and Ireland, declare that I have invented certain new and useful Improvements in Music and Manuscript Holders, of which the followingis a specification. Y Y

This invention'relates to devices used on pianos and similar instruments, music stands and the like for retaining sheets of musicY and the like', or the leaves of books, in the desired position to enable them'to be read. ,Y

The object of the invention is to'provide improved means for the aforesaid purpose, whereby the sheets or leaves maybe readily secured and released without the employment oi' clips, screws,`, strings or other similar securing means. Y A

In carrying vout the invention the holder or frame on which the loose sheets'or booksv are placed, has mounted thereon magnets capable of being adjusted to suit sheets and books of various sizes.

.Each sheet'orleaf has attached thereto metal pieces Vadapted to be' broughtinto contact with the magnets said metal pieces bel ing located at or adjacent the vertical edges of the sheets, and thegouterN edges oi' the leaves of a book.

lVhen it is desired to turn over a sheet or a leaf, the metal pieces are lifted from the magnets, said metal pieces after the sheet or` leaf has been turned, making contact with the magnets at the opposite side of the holder or frame, to those from which they were freed. Y

In order that the invention may Ibe more clearly understood itwill be further described in conjunction with the accompanying drawing in which :V

Figures l, 2 and 3 show holders or frames with magnets mounted thereon.

Figs. 4f and 5 illustrate different Jforms of magnets.

Fig. 6 shows by means of a sectional view the bar of the how electromagnets can be employed, with a circuit break, for cle-magnetizing same when it isvdesired to turn over sheets or leaves. v

The magnets l are permanently magnet ized gud may be shaped as shown in Figs. 1 to The music, manuscript 2 or the like which it is desired to retain on the holder or frame has attached thereto at the corners, and in some cases also half way up the vertical edges, pieces 4 of thin steel. The pieces 4 can be of any suitable shape, and may be inthe form of tags or bars which project beyond the sheet or leaf 2, as in Figs. 3 and 8, or may be disks or the like located one at each side ci". the sheet or leaf 2 as in Figs. 1, 2 and 7,

'A loose sheet of music or the like has a metal piece L1 ateach corner, so that when placed on the holder or frame 3, the pieces l come in contact with and are attracted to magnets l at the corners of the holder or frame 3 and retain the sheet 2 securely thereon. 1 Y

The sheet 2 is freed by merely lifting the pieces l from the magnets l.

Music or the like in book form has metal pieces 4 at the outer corners only of each leaf, said pieces l coming inrcontact with and being attracted to the magnets l as beforew Y In order to Vturn a leaf the pieces lare lifted from the magnets l, and after the leaf has been turned said pieces make contact with the magnets l at the opposite side of Vthe holder or frame 3.

In order that the magnets l may be adjusted on the frame or holder 3 to suit the size of the sheets orleaves 2, they are provided with spring clips 5 which grip and are slidable on bars 6 capable of either vertical or horizontal adjustment cn the holder or frame 3. Each magnet l is therefore capable of being moved horizontally and vertically on'the holder or frame 3 as required.

A number of sheets or leaves 2 can be secured on the holder or ira-me 3 one against the other. TWhen the metal pieces l are in the form of disks or the like on eac-h side of the sheet or leaf, they stack against each other and in turn become magnetized and attract and retain the next disk or the like. '.The metal pieces 4 when in the form of tags or bars projecting from the sheets 3 as in Fig. 2do not stack against each other, but

` are spaced so that each piece comes in actual contact With a magnet l.

On holders or frames 3 used indoors, it is sufiicient to have magnets l and metal pieces 4 at the upper corners only of the holder or frame 3, and sheets or leaves 2 respectively, and in'this case the magnets l need only be adjustable toward and from each other.

Where the sheets or leaves 2 require to bemore securely held, magnets 1 are Yemployed'at each corner of the holder or frame 3 and the sheets or leaves 2 have attached a similar number of pieces 4. It is necessary in the latter case that. the magnets l be adjustable both vertically and horizontally.

If the music or the like'is required to be more firmly held, as for instance When used out of doors, the sheets or leaves 2 can have additional pieces 4 attachedvhalf Way up their vertical edges and additional magnets 1 capable of being at least horizontally adj usted, are provided to suit.

Instead of being secured to the bars of the holder or frame 3, by clips 5, the magnets l can be recessed in the bars 6 of said holder or frame, Fig. 3 in which case they are only capable'of adjustment Von moving the bar.

Instead of using Vpermanent magnets Vl electromagnets 7, Fig. 9 can be employed, the latter being located in a circuit conta-ining a battery 9'and a circuit breaker 10 kept normally closed by a spring'll. The circuit breaker 10 is located in any convenient position and When it is desired to demagnetize the magnets 7, the circuit breaker 10 is operated against the spring 11, by the foot, knee, or hand, leaving the sheet Vor leaf 2 free 'to'be turned. In a building having an electric installation the battery 9 is dispensed with and the Ymagnets 7 are connected with the installation. A switch 8 Vfor putting the circuit out of action when required is also provided.

What I do claim and desire to secure by Letters vPatent of the United States is 1. A holder of thekind described, magnets mounted thereon, and metal pieces attached to the sheets or leaves supported by said holder, adaptedto make contact With said; magnets, substantially as described and illustrated. Y

2. A holder of the kind described, magnets adj ustably mounted thereon; and metal pieces attached to the corners of the sheets or leaves supported by said holder, adapted to make Contact With said magnets, vsubstantially as described and illustrated..v

3. A holder of the kinddescribed, magnets, slidable on bars `adjustable on said holder; and metal pieces on each side of the corners of the sheets or'leaves supported by said holder, adapted to make contact-With said magnets, substantially as described and illustrated. ,y Y j Y 4. A holder of the kinddescribed, magnets slidable on bars adjustable on t, said holder; and metal tabs projecting from the sheets or leaves supported by said holder, adapted to make contact With said magnets, substantially as described and illustrated.`

5. A holder of the rkind described, upper Y and lower magnets slidableV on bars adjustl able vertically Von said holder, intermediate magnets adjustable horizontally 'onsaid holder, and metal pieces on'the sheets Vor leaves supported by saidV holder, substantially as described and illustrated.

In testimony whereof I have aixed my signature in presence of tvvoA Witnesses.
