T heinvention relates to improvements in music .turners as described in the present specification and shown in the accompanying drawings which form partofthe same.
, .,,The invention has for. its object the previ- SiQIl-Qf, device; foriacilitating the turning of theleaves of a book of music in order that a player .-of. a music al instrument need not stop in'the midst; ofrendering a selection .19 in ,orde,r; to turnover apage. A distinctive featureof this invention is that it is providedwith adouble control, one for hand operationand the pthen for foot operation, .eithenofgwhich maybe used at the option ,1? of the-player.
i1{lhe invention consists substantially of a x01 casing :Eorsupporting a music book or the like, clips. .being provided to hold the book open. At the back is a post which carries.an adjustables-rodhaving a clip for p rpoise-o ttac ing tqt e P to be turned, 1 {,The post afotatably mounted and has; an; arm {at itsjlower end that .isSpring- 'ur'gedifor. rotating the post; A detent serves 4' .-to'=lT0ck-the arm-against its spring pressure until the page is to be; turned. A lever is connected?to the;detent-,in.;order to withdraw it .f-rom engagement with the ilIHL WlIlClI lever is .l-oeatedxexteriorly got the box or casing. 9 .On'eiendpof the. lever is connected to a key- .board; .imechanismi for manual operation, while the other end of this lever is connected toa iiootrelease-mechanism. v Referring to-zthei d-rawings, Figure 1 is a perspective Fvi'ew. of. the invention in 1ts adaptation .for use with a piano.
F igurel2- isi a vertical elevation of the mechanism for. turning the leaves. This mechanism is mounted upon a backboard 9 thate-is-removably attached. to the box or casing A Figure?) is a. vertical section taken on the -line33"of Figure 2. In this view the arms of the posts are shown in section. Figure 4is'aahoriz'ontal sectional view taken on the line 44 of Figure 2 showing more particularly the. release. mechanism. I
Figure' 5 :is a. vertical section taken on the line 5'5 of Figure 2.
'FigureaG is'avertical section taken through one of the keys: of. the key-box for manual operation; E'Like. numerals of. reference indicate corresponding part in each of the figures throughout the drawings.
Ihe invention in 1ts preferred form is shown with a pair of posts for turning two leaves of a book of music and it is to be understood in practice the music turner can be constructed to turn a largernumber of leaves it so desired. I I
1O designates the box or casing for housing the mechanism which turns the leaves. Said box or casing preferably has a sloping top 11 and a rest 12 against which the book is placed, which book is shown in outline at 13. The book is held open by clips such as those shown atflt which clamp it'against the rest- 12.
As the mechanism for tur'ing each leaf is of identical construction, a description of one will suffice for both. 15 is .a vertical post journalled in bearings 16, which bearings are supported on an upright member 17 that rises from a back-board l8 that is removably. attached to the: casing. 10. [The bearings 16 serve zto 'supportbotlr'posts which are [located one behind the forh'er as best seen from an inspection: of Figures 1 and 3. TllePOSt 15 is of hollow or tubular construction at-its top in order receive a rod 19 that is telescopically mounted therein and secured bya set screw 20. This rod is bent IL-right aiigles to the post andv carries a clip 2L which in the present instance is of the type commonly used for clipping 'papers and embodies a pa r of;spr1ng, aws. This clip is-rigidly secured to theiod 19 fsuch'a's by means of the set-screw22Q This clip is for the purpose of attachment to a leaf of the book that is to be turned.
The adjustable rod is provided in order to accommodate books of varying heights, it being merely necessary ,to loosen the setscrew and lower or raise the rod inorder to adjust it to books of different heights, the set-screw being tightened when the correct height is reached. The lower end of the post 15 has an arm 23 extending therefrom, which arm is rigidly secured thereto and has an upturned distal end 24 upon which is swiveled a plate 25 that attaches to a tension spring 26 of the coil type. The other end of the spring is attached to the backboard-18 as at 27 preferably by means of a set-screw 28 or other equivalent means whereby its tension may be adjusted. One of the posts extends slightly above the other in order that the arms will not interfere with each other in swinging.
The spring 26 functions to turn the post and in this maiiner turns the leaf that is attached to' the clip 21. "The post is held set or locked by means of the detent 29 until -the-,page;:is. desired' to be;;turned.
This detent projects over the upturned portion of the arm 23 in order to restrain 'it and is retained in this position by a spring 29, the distal end-29 being beveled to click into engagement with the part 2ft of the ar m The detenft is slidably mounted in bearings 30. The other end of the detent hasan eye 31, see 'parti'cularlyfFiglire 4, in which is fitted an 'u'pturned 'end 32 of a rocker 33. The rocker ism'ounted in a hear: ing 34 that also servesto holdjtheicompam ion rocker whiehnactuate s thef trip 'of the mechanism forturi i n'g the'other page, This bearing 34' is supported upon an' extension 35 that is rigidly attache/d ".tothe backs board-318'. frdcker protrudes 'thrdugh an openiiig'in the'fro'iit36 6f theboxf or'f casing and has attached to it ii lever 37; i f point r of. attachment is preferably adjacent, the
top end of the le'terf Itfwill be ,inanifest that ,uporf having "set "o'r' locked, the, post by means of the .detentf 29 can here-leased at any 'timej'for. purposes ofjturning' thepage by merely slightlytiirningthe lever 37 an the proper direction." Upon release of the post the; spring 26 pulls it around in} asemlcircle a "(1 since {theileiajt isattach'ed' w it by means ofJthe clip 21' itis thus' turned. v The manual 1 'eontrolflfor the operation of the lever" 37' consists of a key box .38 which p e lyhas a slopin 6? e' i 'e' ta iable back andf'bott'om joined together in the form of an L plate j which may be attached to the piano or" other" instrumentjin any eonelements iii-the apertures'fiOf- 'lfhe front of the box' is preferably'made slid'able", in order that Iaccess my be had" to the riiechariism therein'e'ontainedi, A'flexible element 42 is a't'tachedto the T werendofthe IeVer 37 and extends to the key box' 38 and passes therein being secured to a peg about which-it is wound in order to keep it taut. Depending from the top 39 is a pair of spaced guides 44 through which the flexible element 42 is threaded and intermediate of these guides is a key 45 which slidablyrises from the topand has its lower end receiving the flexible'element, The key is normally held raised by means of a tension spring 46 so that by simply depressing this keyit will cause the portion of the flexible element lying between the two guides 44 to sag or deflect, thus pullingon' the. lever 37 which in turn withdraws the detent .29 from engagement with the arm 23 of the posts.
The foot control for the lever 37 consists of a flexible element attached tothe upper end; of' such. lever and attached to a vertical rocker 48 at its upper end, the connection being preferably made by means of ajipeg '49 about which the flexible element may be'wound for purposes of maintaining ittaut.-
The. rocker 48 is, connected intermediate of its length to a bracket 50 by means of a pivotal pin 51 which bracket is attached in any conventional manner to an end of the 'p'iano'and also serves to carry the companion rocker arm of the foot control, for the other page; The lower end of the lever has a flexible element 52-similarl'y attached and passed over .a pully 53 of a bracket 54 secured to'the' piano at a point in the vicinity of the player. "The flexible element 52 dependsfro m the pully "53 and is permanently attached to a pedal 1 generally indicated by the numeral 55,'whic h pedal comprises a curved's'pring-56' forattaehment to the piano in the vicinity of the ,pla'yers feet-and a toepiece 575presenting a= depressible pad. The page is turned by the foot controlby'simply depressing the member 57 by=mean'sof the foot'.which pulls upon the flexible element 52 and rocks the rocker 48 causing it to pull upon the flexible element 47' and thus moving the lever 37"--in. the requiredjdirec tion for releasingith'e detent- 29L What I claim'is": v1.
