For convenience in understanding the relative disposition of the parts of my attachment, I have shown an upright piano of standard size and ofordinary construction, wherein A is the case, B the upper front board, C the lower front board, D the fallboard, E the sliding trackerboard panel, F
the strings, G the piano action, H the piano abstract. J the action rail, K'the piano keys, L the key-bed. M the key s ip, N the sounding board, 0 the back uprights, I the head block and Q the piano string frame.
It is, however, obvious that many modifications in the size, arrangement, connections and dis osition of the parts of my device, depending to some extent upon the style and size of the instrument in which it is to be placed, may be made without dea ting from the principles of my invention.
lVithin the lower po tion of the piano case. below the key-bed, I provide means for detachably securing the bellows mechanism, which in this class of mechanical players usually comprises a chest. reservoirs, ports and pumps operated by pedal connections adapted to create pneumatic tension within the chest. the latter communicating through various windways. having valves under cont ol of the operator or the music sheet with the player parts which throw the piano hammers and propel and guide the music sheet.
My preferred form of sectional bellows construction is made the subject of a copend ng application, issued as Patent No. 914.351, of March 2, 1909, and I will but briefly describe it, it being understood that my construction of the bellows chest in separately removable sections or divisions facilitates attachment and detachment thereof within the instrument case and that variation in the sectional construction and arrangement may be made.
Near the middle of the piano, I provide an upright support 1. having two vertically disposed straps 8 and 3 countersunk in the rear surface and ent over the'top at right anglesso that they may be screwed, or otherwise fastened. to the key-bed at 2, the support 1 being similarly secured at the lower end to the sting frame Q of the piano. (See F g. 1.) To the opposite interior ends of the piano case are secu ed a pair of upr ght cleats 5 and 5 on the left hand and G and G on the right. both pairs tapering inwardly so as to form oppositely disposed recesses or sockets 7 and 7. The cleats on the same side of the case are far enough apart to permit the outer ends of the bellows che t sections to fit snugly hetwecn them. Iligidlv secured to the u right 1. or made. integral with it. is a vertical wedge-block o tongue 1. ta ering outwardly and of sutticient si' e to fill the intervening space between adiacent ends of the sections hen they are set in place.
I provide a bellows chest com osed of a plurality of separately removable sections or divisions. In the drawings I ha e shown two sections or divisions separately placed or attached so they may be taken out one at a time, having the usual tension creating and retaining mechanism comprising pumpers 8 and 8, pedals 9 and 9, reservoirs l0 and 10'" and chests 11 and 11. The sections are set in the instrument by thrusting the outer ends into the sockets 7 and 7, and pressing the inner ends against the sides of the wedge-member 4, in which position they may be detachably fastened by bolts 13, suitably threaded and provided with nuts. In order that the pneumatic tension may be the same within the sections, I cut openings therein and fit the ends of windway connections 12 and 12 thereto. The configuration of the sections is such that-ready access may be had to the string frame through the opening 15.
Mounted on the left hand section is a valve chamber 0 and a tension regulator or governor (Z, while similarly mounted on the right hand section is a valve chamber 0' and a similar governor d. Chests 11 and 11 communicate with chambers 0 and 0 respectively through passages provided with valves and rod connections under control of the operator. I prefer to use a governoi comprising an expansible air chamber, to a movable member of which is attached a ball valve d normally held from its seat in the passage to thechest by spring (1 and adapted automatically to d iminish or in crease the opening therein in accordance with the increase or decrease of the pneumatic tension in the chamber. Valve chamber 0 is provided with high tension direct and low tension indirect communications to chest 11, the direct communication being through passage 19 and the indirect communication through opening 18. channel 16. opening 17, governor (Z andopening 9.0. Channel 16 is preferably disposed within the top of the chest 11. The opening 19 may be opened and closed independently of. or simultaneously with, opening 18 by valves controlled by the modulating and rewind levers.
From valve chamber 0 lead the windwavs throu h which pneumatic tension is communicated to the mechanism for actuating the piano hammers and for shifting the connections to apply alternately the power of the motor to advancing and rcwinding the music sheet. I prefer to detachably couple these windways to the cham er 0 by cap ping the latter with a face plate ha ing a tubular opening 22 to which a pipe23 leads from the chambers 81 of the pneumatic actions 24. Valve chamber ris similarly provided with high tension direct and low tension indirect communications to chest 11 controlled by independent valves operated by the rewind and tempo levers. A channel within the top of chest 11 communicates with governor (5 through opening 26 and with valve chamber (2 through opening 27. The valve chamber 0' communicates directly with chest ll through passage 28 and indirectly through opening 27, channel 25, opening 26, governor cl, and opening 29. A pipe coupling 30 on chamber 0 is provided with a flexible pipe 31 bringing this chamber into communication with the motor which operates the sheet propelling mechanism.
The levers by which the various parts of my device are preferably controlled are four in number and areconvenientlyarranged below the keys and provided with handles and a finger rest on the front of the instrun'icnt. I prefer to construct this rest by merely cutting away or recessing the key-slip M and providing four slots therein, each adapted to permit lateral movement of the lever extending therethrough. The bottom of this recess m affords a rest for the fingers.
Tempo-lever 33 extends backward in a horizontal plane through its slot in recess m and is pivoted at 36 to the key-bed L. To the rear or inner end of this lever is attached an end of connecting rod 37, the other end of which is secured to valve-stem 38 on valve 39 in chamber 0. This valve controls opening 27 between chamber (2 and governor (Z'. Near the forward end of lever 33 is fastened one end of a link connection 40, the other end being attached to an arm of a double crank 41, the other crank-arm being connected to the lower end of a swinging arm 42 pivotally secured at 43 by bracket 4H: attached to case A. To the upper end of this swinging arm 42 is adjustably secured a rod 45 leading to a tempo indicator or scale 48. Rod 45 is provided with a double eye or universal joint 46, and an indicating finger a? adapted to travel along the scale 48.
Modulating-lever 3t extends backward in a horizontal plane through its slot in recess m and is pivoted to the key-bed at 40. To the rear end of this lever is attached one end of link 50, the other end being adjustablv secured to valve-rod 51 provided with collar 52 within the valve chamber 0. Valve-rod 51 passes through ear projecting upwardly from valve Collar 52, impinging against ear 55, closes the valve 53 over opening 19. This valve is opened by spring 5% within chamber (2, one end of which is attached to the wall of the chamber and the other to the ear 55 on the side adjacent to the collar. \Vhen lever 53% is drawn to the left by the operator the valve closes the direct opening 19 between chest 11 and chamber 0. To return lever 34- to its initial position upon release by the operator a spring 56 is provided attached to the piano case at 57 and to the link 50. By operating lever 34, the direct passage be tween chamber 0 and chest 11 is closed, thereby bringing a low tension to bear in the action pneumatics. \Vhen the valve controlling this direct passage is open, high tension is created in the chamber, so as to give the most powerful action upon the striking mechanism, while when this valve is closed communication is had only by an indirect passage through the governor.
Sustaining-lever 35 extends backward in a horizontal plane through its slot in recess m and is pivoted to the key-bed L near its rear or inner end at 58. To this rear end is attached one end of a link 55), the other end thereof being connected with one member of a bell-crank (it), pivoted at (31, the other member engaging the upright rod (32 leadingfrom the sustaining pedal of the piano. This rod ()2 connects the sustaining pedal for operating the usual piano mechanism for removing the dampers from the strings.
Rewindingdever 32 extends backward in a horizontal plane through its slot in recess m and is pivoted near its center at ()3 to keybed L. Secured to the rear or inner end of the lever is a link connection (it, the right hand end of which is coupled to valve-stem on valve 66 in chamber 0', over opening 28 while the left hand end is coupled to valve-stem 67 on valve 68 in chamber 0 over opening 18. For the purpose of affording an adjustable connection of valve-stem 67 on valve 68, I provide a collar (39 adj ustably secured by aset screw 70 to said valve-stem, which, in turn. is confined between two upwardly extending ears or flanges 70 of the valve. Valve-stem (37 passes through car 55 on valve 55) and extends through a hearing in the end of chamber a. Surrounding the valve-stem G7 and adjacent to car 55 on the left hand side, as shown in Figs. (3 and 7, is an adjustably secured collar 71. Connected to valve-stem ('37 on the outside of the right hand end of chamber (2 is a valve rod 72, adjustably connected to valve 73, and adapted to open and close a vent or opening 7% between valve chamber 0 and the outside air. This valve is confined within the guide 75. \Vhen lever 32 is thrown to the left from the position it normally occupies and as shown in Fig. 1, the -alves 53 and ($8 in the valve chamber (1 are closed while valve 66 in valve chamber 0 is opened. This movement also opens the valve 73, uncovering opening 74 in chamber 0, which instanta neously allows outside air to enter and relieves tension upon the action pneumatics and by means of the conduits 127, 199 and 198 upon the bellows 153. The removal of this tension permits expansion of the bellows referred to. thereby shifting the mechanism through which the rolls are operated into position for rewinding the music. At the same time high tension is applied to the motor for operation at the maximum speed.
Above the keys and directly back of the front key-board casing are mounted the action pneumatics detachably secured to the case A by plates 76 as shown in Fig. 12. In constructing the pneumatics, I prefer to form two cross-pieces 77 and 77, one mounted above the other and both joined at the opposite ends by blocks 78 having connectingwind passages. Each of these crosspieces is formed of an upper and lower member 79 and 80, respectively. Upon each of the upper members 79, I mount a row of action pneumatics, these being so arranged and of such size and shape as to allow one row to be placed over the other and each pneumatic directly above one of the keys of the instrument. Each pneumatic 83 is provided with an opening 8t, registering with an opening 85, communicating with passage 86. within member 79. Within each of the passages to the rear thereof, is a thimble extension 87 affording communication between passage 80 and chamber 81. Beneath extension 87. and in line therewith, is placed a flexible diaphragm 88 covering opening 89 leading from chamber 81. To the rear of each member 80 of the cross-pieces 77, is a row of thimbles 90 each of which connects with a passage 91 leading from the under side of one of the diaphragms 88. Loosely attached upon each diaphragm, is a disk 92 with stem 93, passing through guides 9-1 and carrying a valve 95, adapted to alternately open and close the opening to thimble 87 and the opening 96 to the outside air. Valve is secured to stem 93, by means of washers 97 held in place by elastic or accommodating stops 98. From each nipple 90 and detachably coupled thereto are the lower sections 9 of the tracker tubes.
I prefer to apply the power of the action .pneumatics to the piano action by substantially the same 'means as those shown in my co-pending application issued as Patent No. 833 000 of October 9th, 1906. The movable members 100 of pneumatics 83 are provided with projections 101 through which pass stems 102, which are provided with nuts 103. Yielding washers 101 are placed between the nuts and the projections 101. Each stem is pivoted at its upper end 105 to the outer end of a horizontally disposed lever 100, pivoted at 107 within a bearing strip 108. The rear end of the lever is rounded and cushioned to contact when the pneumatic is collapsed with the under side of a spoon 109 projecting forward from the piano abstract H. It may be found convenient to provide an adjustable bumper 110 above each lever held in position by cross piece'111. By this attachment between the mechanical or pneumatic action and the piano action there is no interference with manual playing. To
cross pieces 111 is remo ably secured an upright frame 112. to which is detachablv secured venting chamber 114. The box 113 comprises a rear Wall 115, the top and. bottom flanges 116, provided with recesses 117, within which is placed-glass or transparent sections fitted in gaskets 119 and clamped in place by buttons 120, pivoted at 121 to flanges 116. \Vithin wall are cut a series of vertical holes 122, provided at the top and bottom with nipples 123. To the lower end of each lower nipple is attached one of the lower tracker tube sections 99, and like wise to the upper end of each upper nipple is similarly attached one of the upper sections 99. The latter lead to nipples 124: on the rear of the tracker-board f to which they are secured. The tracker-tubes are pneumatically exhausted through pin holes in disks 126, leading to venting chamber 114, said chamber communicating with the right hand end of the upper cross piece chamber 81 through pipe connections 127. A slight tension is thus created in the tracker tubes sufficient when the tubes are closed by the sheet to prevent operation of valves 95, but not sufficient to exhaust them, or any one of them when uncovered by the sheet. This tends to hold the sheet and tracker board in close contact.
The motor or wind engine. the tracker board, rewind and takeup rolls, the sheet guiding devices for correcting registration, the shiftable connections for alternately coupling the motor to advance the rolls and thereafter shift them to reverse the rolls, and the pneumatically controlled mechanism for obtaining this reversal, I prefer to mount near the top of the case. This may l e conveniently done by providing a rectangular frame detachably secured tothe back of the piano. having a base q extending out to the right hand side of case A. The tracker loard is mounted in the usual manner within the f 'ame r and leading from it are curved rear sections 128, forming recesses for the music or rewinding roll 12., and the winding or take up roll 21 which are journaled in the frame r The arrangement of the motor o wind engine, the tracker board, the rewind and take up rolls and the connections for alternatelv coupling the motor to advance. and reverse the rolls, may be of any convenient construction. I prefer. however, to arrange them as shown in the drawings. At the right hand end of frame (I is mounted a shaft 129. having a slotted socket or head 130 within the frame adapted to receive the usual gudgeon of the music roll,
the pin 131 of which engages the slot in head 130. Outside the rectangular frame a disk 129 is keyed to shaft 129. Bearing against this disk is a spring brake or tension member adapted to increase tension on the sheet.
In line with shaft 129 at the'opposite side of the rectangular frame r is a spring pressed socket 132 normally held against the gudgeon of the music roll by spring 133 (Fig. 1). The above described mechanism affords m ans for inserting music rolls of uniform standard length and for taking them out again when rewound. Take up roll 2' is mounted on shaft 13+. having bearings within the frame g. This shaft extends beyond the frame on the right hand side as shown in Fig. 17, being preferably pointed at this end and bearing against spring 135 which tends to thrust the roll to the left. Rigidly mounted on shaft 131 is gear 131- adjacent to the rectangular frame. Adjacent to shaft 13-1 is placed a shaft 135, suitably supported in bearings. and pro vided with a loose sprocket 13(3 held against lateral movement thereon by an arm 137 which enters a groove in the hub portion of the sprocket. ()n the left hand face of sprocket 136 is mounted a contact roll 138. Between the sprocket 136 and the rcctangu lar frame y. shaft 135 is provided with a pinion 139. having a head 11H) carrying on its right hand face pins 141 adapted to engage contact roll 138 on sprocket 136, when thrown to the right to occupy the position shown in Fig. 17. Head 110 is pinned to shaft 135 and provided with an annular groove 1+2 adapted to engage an upwardly extending finger 11-3. mounted on shaft H4 directly beneath shaft 135 and parallel thereto.
Upon the base extension y of the rectangular frame are uprights 1&5 supporting a suitable wind motor This motor being well known in the art is not more particularly described. It is here shown as operated from the flexible windwav or pipe connection 31. The motor crank shaft 146 has lrearings in both the uprights 1-t5 and is in axial alinement with shaft 135. At its left hand end shaft 146 is provided with. a disk H7 pinned thereto. llxtcnding out from this disk is a pin llfw adapted to engage at all times anti-friction roller 1-l-9 fastened on the end of shaft 135. Upon shaft 129 is mounted a sprocket 150. A sprocket chain 151 passes around sprockets 150 and 13f). Intermediate the two sprcckets is a belt tightener 152 made adjustable in the usual manner to vary the tension of the sprocket chain.
lVhile I have in the foregoing described a convenient form of shiftahle coupling mechanism for alternately operatively uniting the motorand rolls so as to advance the latter and thereafter operatively uniting them so as to reverse this movement. the invention is not limited to the particular constructicn as shown but contemplates the use of any m chanism which may be coupled to successively operate in dirccticns determined by a shifting device contrcllcd pneumatically frcm the windways. I prefer to acconn l'sh this obic'ct by bro i'ling a pneumatic 153 mounted upon the base extension g, its movable member having an arm or link 154 attached to one arm of the bell crank 155, the other arm having pivoted thereto an end of link 156. which in turn is pivoted at the opposite end to shaft 144. It will be seen by reference to Figs. 12 and 17 that shaft 144: will be forced to the left by collapse and to the right by infiaticn of pneumatic 153. This shaft carries finger 143. which engages groove 142 in the head of pinion 139 and thereby causes pins 1-t1 to engage contact roll 138 when thrust in one direction or it throws pinion 139 into mesh with the gear 134 when thrust in the opposite directicn. Pneumatic 153 is provided through conduits 198, 199 and 127 with operating tension from the air chamber of the pneumatic action 2 1, and its collapse is dependent upon the presence of operating tension therein. Upon removal of this tensicn from the pneumatic action, pneumatic 153 returns to normal or inflated position by the action of spring 157, one end of which is secured to one of the uprights 145, and the other to finger 143. Behind shafts 129 and 131 is suitably mounted an oblique upright shaft 158. At its upper end this shaft carries an arm 159 in alinement with the axis of the shaft 129. hearing against the hub of sprocket 150, while near its lower end it carries a similar arm 160 in alinement with the aXis of shaft 134 hearing against collar 161 attached to shaft 131. Shaft 158 is provided with a crank 162 connecting with a shifting rod 163. operated by pneumatics hereinafter described.
The tracker-boa rd has the usual orifices f, each comn'mnicating with one of the upper sections 99 of the tracker tubes above described. K indicates the music sheet and 7c the perforations tllcrcon adapted to operate the. action pneumatics in proper sequence for playing a tune. Adiacent to these orifices, but out of alinement therewith. are pairs of slits or mouth pieces f and f arranged altcrnatcly across the tracker-board. From each of the orifices is a pneumatic connection'to a pipe j and similarly from f is a pneumatic connection to a pipe From pipe 7 leads pipe 164 and from f leads pipe 165 to the pneumatics Z Z. respectively. (Fig. 12). These pneumatics may be constructed. operated and controlled as to their operation by the pipes 164 and 165 in any ordinary or desirable manner. but I prefer in this instance the construction shown in Fig. 12 and in the patent granted in part to me October (3. 1906. and numbered 332.982. In the figure referred to Z represents a central section or valve-clmmlrer having single pneumatics 1" 7 attached on opposite sidcs. The movable members of the pncumatics are each provided with a bifurcated finger extension 191 embracing shifting rod 163 and adapted to contact with colla-rs 194 upon said rod. Upon the central section Z is an extension affording a support for the rod 163, and adjacent to this support, upon either side thereof, is a collar 193 adiustably secured to the rod to limit its lateral movement as it is thrust in either direction by the collapse of the pneumatics Z Z Operating tension is applied through the conduit or pipe 197.
Vhen the music sheet is in normal position. the perforations registering properly with the tracker-board orifices f the slits or mouth pieces 7 and f will be covered with the sheet. Should the sheet. however, become abnormally shifted to the left, it will uncover one or more of the slits f allowing air to enter tube 164, operate valve 174 and cause collapse of pneumatic Z The collapse of pneumatic Z will shift or slide the rod 163 to the right by bringing bifurcated finger 191 in contact with collar 191. This shifting causes shaft 158 to oscillate and turn arm 160, bearing against collar 161, to thrust shaft 134 of the take-up roll to the right. thus causing the roll to shift the sheet to the right and cover the orifices f thereby bringing about proper registration of the perforations and tracker-board orifices. It being desirable that both rolls shall move simultaneously, it will be seen by inspection of the drawings that upon oscillation of shaft 158, as above described, arm 159 will draw away from the hub extension of sprocket 150 on shaft 129 and simultaneously the tension of spring 133 will shift the music-roll it into contact with the arm 159. \Vhen, however. the perforated sheet becomes abnormally shifted to the right it will uncover one 01"11101'8 of the slits f allowing air to enter the tube or pipe 165 and pass into a corresponding system of passages and valves, and causecollapse of pneumatic Z This causes the bifurcated finger on the pneumatic Z to contact with a collar and oscillate shaft 158 in the reverse direction from that caused by the collapse of pneumatic-Z The arm 159 will thus be thrust against the collar on shaft 129 against the yielding spring 133 and the spring 135 will cause shaft 134 to follow up the arm 160, thus shifting the musicsheet to the left to cover the orifices f and bring about proper registration. Also mounted on the base extension 1 of frame 9 is a governor (Z conveniently disposed beneath the motor. From pneumatic 153 is a flexible tubular connection 198 which leads to the governor cl to which is also connected the flexible pipe 197, leading from the pneumatics Z Z (Fig. 12). On the opposite side of governor d is attached a flexible tube 199 leading to a. branch of a pipe 127. In this manner governed tension only is applied to the neumatics Z and Z and reversing pneumatic 153. Governor (Z is similar in construction to governors (Z and d, heretofore described. Its adjustable valve (Z is set to permit only a slight suction on pneumatic 153 and pneumatics Z and Z thereby preventing the latter from throwing the sheet too far when correcting registration and causing the former to operate alike at all times. It is evident that while governor d delivers operating tension to pneumatics l and Z and 153, it in turn receives power from pneumatic action 24 through conduits 199 and 127. Vhen, therefore, tension is admitted to the pn umatic action, all the devices concerned in the forward or playing movement of the music sheet are thereby rendered ready for operation, and upon withdrawal of this tensionfrom the action the devices controlled from the tracker are rendered inoperative and the reversal of the sheetpropelling mechanism is permitted.
As shown in Fig. 2, I hinge or otherwise pivotally secure to key-bed L beneath the manual keys K at the points n, a bar 72 shown in its lowered position in this figure. This bar is adapted to be rocked so as to contact with the under surfaces of the manual keys. thereby affording a rest for them and locking them against movement. To throw the bar at into this position, I attach to the same a bracket n to which is connected one end of a link n (Figs. 13 and 15), its other end being attached to a crank n on a vertical shaft n extending through the key-bed L. Beneath the keybed this shaft is provided with a similar crank-arm 0. normally held in the position shown in Figs. 14 and 15 by a spring 0. A pin or finger-grasp o is provided on the under side of this arm, for the purpose of turning the shaft 72 and locking the same when the bar is raised in contact with the keys to occupy the position represented by dotted lines in Fig. 15 by means of the spring 0 attached to the outer side of keybed L. For the purpose of limiting the throw of the arm 0 and thereby of bar n, I provide on the outer side of the key-bed L stops 0.
