of the actuating levers of the player mechanism, showing by full and dot-ted lines various positions the actuating levers assume during the operation of the player; Fig. 16 is an enlarged perspective view of a portion of the expression mechanism of the player; Fig. 17 is a perspective view of a detached gravity arm; Fig. 18 is a perspective view of a cross head forming part of the rewind mechanism; Fig. 19 is a perspective view of a train of mechanism forming part of the piano player; Fig.20 is a detail perspective view of a part of the retaining rod for the selector levers.

Reference will first be had to Fig. 1 of the drawings showing those parts of an upright piano to which the player mechanism is especially related. The reference numeral 1 denotes the lower front panel of a piano case, 2 a movable section of said panel, 3 an upper front panel, 4 a movable section thereof, 5 the key bed, 6 the key board for fulcrumed keys 7, 8 the ledge, 9 a portion of the covering for the

keys

7, and 10 the end walls of the piano case, these portions, with the exception of the

movable sections

2 and 4 of the panels 1 and 3 respectively being common to the ordinary type of piano. The player mechanism is located in the upper part of the piano case and it is preferable to locate the operating mechanism in the lower part of the case. The operating mechanism comprises an electric motor 11 operatalole from a suitable source of electrical energy located either in the base of the piano case or at some other remote point with suitable connections with the motor. The motor is supported upon a bracket 12, carried by the inner side of the panel 1 adjacent to the detachable section 2 of said panel. The armature 13 of the motor 11 has an eccentric 14 and loosely mounted upon said eccentric is a band or ring 15 suitably connected to an operating rod 16, said rod extending upwardly through openings 17 provided therefor in the key bed 5 and the board (3 into the upper part of the piano case.

Reference will now be had to Figs. 1, 3, T and 8, wherein there is illustrated the player mechanism that is located in the upper part of the piano case in proximity to the movable section 4 of the upper panel 3 of said piano case, whereby said movable section can be swung to an open posit-ion and the selector mechanism of the player placed into a playing condition. The player mechanism is mounted between two

end plates

18 and 19 connected by a longitudinal bar 20 suitably secured to a longitudinal'frame 21 connecting the end walls 10 of the piano case. The'end

plates

18 and 19 have depending apertured lugs 22 and these lugs can be connected to brackets 23, carried by the inner side of the panel 3, adjacent to the opening closed by the movable section of said panel. Slidably arranged against the inner sides of the

plates

18 and 19 are the ends of a reciprocatory frame best shown in F igs: 3, 7 and 8, comprising

side bars

25 and 25 having the lower ends thereof connected by a longitudinal rod 26, and connected to this rod, intermediate the ends thereof, is the upper end of the operating rod 16. The upper ends of the bars 25' and 25 have heads 27 and connected to said heads, by screws 28, are the lower ends of retractile springs 29 having the upper ends thereof connected to screws or pins 30, carried by the inner sides of the

plates

18 and 19. These springs are adapted to retain the reciprocatory frame normally in an elevated position, said frame being lowered once in each revolution of the eccentric 14 of the motor 11. The

bars

25 and 25 are connect ed by a longitudinal pivot rod 31, one end of said rod extending through a slot 32 provided therefor in, the end plate 18 for a purpose that will presently appear. The opposite end of said pivot rod extends into a similar slot in the plate 19, the ends of said rod guiding the reciprocatory frame in its movement between the

end plates

18 and 19. Pivotally mounted upon the rod 31 are operating levers 33, corresponding in number to the keys 7 of the piano. The upper ends of these levers are reduced and connected b coiled retractile springs 34 to a bar 35 connecting the heads 27 of the

bars

25 and 25. The upper ends of the levers 33 normally engage a cylindrical cushion 36, carried by a rod 37, connecting the heads 27 of the reciprocatory frame, said cushion limiting the movement of the operating levers 33 in one direction, as will presently appear. The lower ends of the operating levers are cut away in order to provide

beveled prongs

38 and 39, the cut away portion of each lever prov ding a slot 40. The operating levers are spaced apart by spacing washers 40 to insure independent action of the loosely mounted operating levers.

Associated with the operating levers 33 shown in F ig. 5 are pivoted selector levers 41, pivoted releasable locking levers 42 and pivoted key actuating levers 43 and Strike levers 47 corresponding in number to said operating levers and the keys 7 of the piano. The key actuating levers are spaced similar to the operating levers upon a rod 44 con necting the

end plates

18 and 19, said levers having rearward extensions 45 connected to cushion 59, carried by a rod 60 cords 46, the purpose of which will hereinafter appear. The key levers 43 have forward extensions 48 provided with

notches

49 and 50 adapted to receive the prongs 38 of the operating levers 33. The key levers also have vertical extensions 51 normally engaging in the notches 52 provided there for in the lower edges of the locking levers 42. These locking levers are equally spaced upon a rod 53 connecting the

end plates

18 and 19, said levers having the forward ends thereof provided with depending extensions 54, and the rear ends of said levers connected to coiled retractile springs 55 secured to a bar 56 connecting the

end plates

18 and 19. The locking levers 42 are limited in their downward movement by a cylindrical cushion 57, carried by a rod 58, connecting the

end plates

18 and 19, and the key levers are limited in their movement by a cylindrical connecting the

end plates

18 and 19.

The selector levers 41 are equally spaced upon a rod 61 connecting the

end plates

18 and 19,.said selector levers having the lower ends thereof beveled, as at 62 and the upper ends thereof cut away, as at 63 to provide beveled prongs 64. The selector levers 41 are arranged in groups with the groups divisioned or separated by arms 65, carried by a bar 66 connecting the

end plates

18 and 19, said arms preventing a wabbling 0r sagging movement of said levers. The selector levers are limited in their movement by a cylindrical cushion 67, carried by a rod 68 connecting the

end plates

18 and 19.

The lower beveled ends 62 of the selector levers 41 have outwardly projecting pins 69 extending into a tapering slot 70 formed by

tracker bars

71 and 72 connecting the

plates

18 and 19. Located in front of said bars, in proximity to the slot 70, is a retaining rod 73 having one side notched or slotted as at 73, as best shown in Fig. 8 to provide clearance for the pins 69. The retaining rod 73 has the ends thereof supported by cranks 74 mounted upon a rod 75, journaled in the

plates

18 and 19, said plates being cut away or slotted, as at 76 to provide clearance for the retaining rod 73. The rod 73 is held normally in a lowered position by coiled retractile springs 74 connecting the cranks 74 and the

plates

18 and 19. The rod has a flat surface 75* adapted to engage the rear edges of the selector levers 41.

Movably arranged between the rod 73 and the tracker bars 71 and 72 is a sheet of perforated paper 77 similar to the sheet of paper at present used in connection with various types of piano players. The sheet of perforated paper is wound upon a roll 78 detachably and revolnbly supported between the

plates

18 and 19. The ends of the roll are detachably supported by

pintles

79 and 80, the former being yieldably supported in the end plate 19 and the latter revolubly supported in the end plate 18 by a clutching member 82. The pintle 79 has heads 79" and 79 and encircling said pintle, between the head 79 and the plate 19, is a compression spring 81. The opposite end of the perforated sheet 77 is detachably connected in the ordinary and well-known manner to a takeup roll 83 mounted upon a shaft 84, journaled in the

end plates

18 and 19. The

shaft 84 protrudes through the end plate 18 and is provided with a ratchet wheel 85. l lngaging the teeth of said ratchet wheels are

pawls

80 and 87, the former being pivotally supported by a pin 88, carried by an L-shaped gravity arm 8!) slidably held against the outer side of the end plate 18 by a screw 90. The L-shaped arm 89 is slotted, as at 91 to receive the screw 90 and said arm is located adjacent to a slot 92 through which protrudes the end of the rod 26. The end of the rod 20 engages the under side of a pin 94 carried by the upper end of the arm 89. The arm 89 is cut away, as at. 95 to provide clearance for the end of the rod when said rod is lowered by the motor 11.

The pawl 86 is normally retained in engagement with the ratchet wheel 85 bya coiled retractile spring 90 connected to a pin 07. carried by the lower end of the L-shaped arm 89. The pawl 87 is pivotally mounted upon a pin 98 carried by the end plate 18 and said pawl is normally retained in engagement with the ratchet wheel 85 by a coiled retractile spring 90 connected to a pin 100, carried by the end plate 18. The pawl 87 is connected by a cord 101 to an eccentrically mounted pin 102, carried by the end of the rod 7-5, and said eccentric pin 102 is connected by a cord 103 to the upper end of a kickotf member 104. slidably mounted in a bracket 10.) carried by the end plate 18. The kick-off men'lber 104 extends under the pawl 80 to move said pawl out of engagement with the ratchet wheel 85, when said kick-elf member is elevated by an upward movement of the pin 102. This pin, through the medium of the cord 101, moves the pawl 87 out of engagement with the ratchet wheel 85 simultaneously with the release movement of the pawl 80.

The crank 74 supported at the end plate 18 is elevated by a small crank 108 pivotally mounted upon a pin 107. carried by the end plate 18. The crank 100 has a handle 108, in proximity to the detachable section 4 of the upper panel 3, whereby the retaining rod 73 can be elevated when the perforated sheet 77 is to be rewound upon the roll 78. The upper edge of the crank 74, at the end plate 18. is connected by a rod 100 to the lower end of a vertical wedge 110 movably mounted in a bracket 111, carried by the end plate 18. The upper end of the Wedge is adapted to engage a hinged member 112,

pivotally connected to an outwardly extending lug 113, carried by one end of across head 114. One end of the cross head 144 is cut away, as at 123 to provide clearance for the rounded protruding end of the rod 31. The member 112 has a vertical arm 115 with the upper end thereof forked, as at 110 to span the end of a shaft 117, journaled in the end plate 18 to support the pintle 80 and the clutch member 82. Mounted upon the shaft 111" is a ratchet wheel 118 having the inner face thereof provided with a clutch member 11%) adapted to engage the member 82. Encircling said clutch member, between the ratchet wheel 118 and the end plate 18, is a coiled spring 82" holding said clutch members normally apart. Engaging the ratchet wheel 118 are

pawls

120 and 121 pivotally connected, as at 122 to the upper ends of rods 123 carried by the cross head 114, said rods being slidably mounted in guides 124, carried by the end plate 18. The rods 123 are movably supported in bearings 124, carried by the end plate 18 (Fig. 6). The

pawls

120 and 121 are held in engagement with the ratchet wheel 118 by coiled

retractile springs

120 and 121* connecting said pawls and the rods 123.

The hinged member 112, when swung inwardly toward the cross head 114 by an upward movement of the wedge 110, engages the rounded protruding end of the pivot rod 31, whereby said member and the cross head 114 will be elevated. The cross head 114 is lowered by a retractile spring 114 connecting the lug 113 and the plate 18. It is through the medium of the spring 114 and an up stroke of the rod 31 that the cross head 114 is vertically reciprocated, when said hinged member 112 is held in the path of the rod 31 by the wedge 110. A down ward movement; of the cross head 114 and the member 112 is limited by a stop pin 125, carried by the end plate 18, as it is not necessary for the rods 123 to make the same length of stroke as the operating levers 33. The stroke of the rods 123 is sufficient for the purposes for which they are intended as will hereinafter appear.

Reference will now be had to Figs. 1. 2 and 10 showing the expression mechanism and the connection between the keys 7 and the key levers 43. Connecting the end walls 10 of the piano case above the keys 7 is a platform 120 hav ng the ends thereof provided with vertical bearings 127. Connecting said bearings are

rods

128, 129 and 130. Pivotally mounted upon the rod 128 are two

tension boards

131 and 132, the combined length of these boards being equivalent to the length of the platform 120. At the confronting ends of said boards, the board 132 cut awav to provide a wedge-way 133 upon which is slidably mounted a Wedge 134. The upper surface of this wedge engages a pivoted plate 135. carried by the confronting ends of the

boards

132 and 133 at the rear edges of said boards. The forward edge of the plate 135 is connected by a cord 130 to one end of a bell crank lever 137 pivotally mounted in a slot 138 provided therefor in the platform 126. said lever being pivotally supported between lugs 13$) carried by the upper surface of the platform 1%. The opposite end of the bell crank lever 137 is connected to a cord 110 extending over a sheave 11]. carried by the support 142 of the covering or lid 5). said cord extending downwardly through openings 113 provided therefor in the bed 5 and the board (3. The cord 110 extends under a sheave 1H. carried by the key bed 5. adjacent to the lower end of the opening 143. The cord 110 extends for 'ardly under the key bed 5 and is connected to an expression lever 1-Ll5 pivotally connected. as at 1 A to the under side of the key bed contiguous to the front edge thereof. The wedge 134: is connected by a retractile spring 1 17 to a post 118. carried by the platform 11213. The spring 117 is connected to the forward large end of the wedge 131 and the rear small end thereof is connected by a cord 11% to the upper end of a lever 150. The lever 150 is pivotally mounted by a pin 151 between lugs carried by the rear edge of the platform 126. The lower end of the lever 150 is connected to a. cord and this cord passes over sheaves arranged beside the sheaves 141 and 111. said cord having the end thereof connected to a second operating lever 15% located adjacent to the operating lever 1-15. Arranged between the

tension boards

131 and 132 and the platform 1520 are a plurality of compres sion springs 155. and connected to the forward edges of said tension boards. by retractile springs 156. are the forward ends of strike levers 17. these levers having the rear ends thereof connected by cords 157 to the keys 7 of the piano. The strike levers 47 are fulcrumed upon the rod 129 and the rod 134) limits the upward movement of the rear ends of said strike levers. although said rod serves more as a brace or tie, for the bear ings 1:27. (onnected to the forward ends of the strike levers 17 are cords 158 having the upper ends thereof connected to pivoted guides 159. carried by both sides of a bar 160 supported by the inner side of the panel 3. The cord 158 passes over sh a1 ves 1(31 carried by the ledge 8. The guides 15$) are connected by cords N32 to couplers 1o?) pivotally mounted upon a curved rod lost. carried by the end walls 1!) of the piano. The couplers 163 are connected by cords 155 to bell crank levers 1G6 pivotally mounted upon a rod 157 carried by depending bearings 1138 of the

end plates

18 and 19. The bell crank levers 108 are connected to the lower ends of the cords 16. The guides 159, rods 16 1 and 167, couplers 1G3 and bell crank levers 166 constitute a spreading frame or means whereby the connections from the key levers 43 can be distributed to the various strike levers 17.

Reference will now be had to Figs. 8 to 13 inclusive showing a retracting device that is employed for moving the selector levers during an upward stroke of the reciprocatory frame and a downward movement of the perforated sheet of paper 77, said retracting device being employed whereby the perforated sheet of paper is not liable to injury by the pins (39. The retracting device is located in the rear of the selector levers 41 and below the rod (38. The inner sides of the

bars

25 and 25 are provided with brackets 16!) having apertured lugs 170. Pivotally connected to said lugs are dogs 171 having pins 172 extending over the lugs 170 and connected by coiled retractile springs 178 to said lugs. Adapted to engage the dogs 171 are pins 174. carried by arms 175 pivotally connected, as at 176 to the inner sides of the

end plates

18 and 19. The upper ends of the arms 1.75 are connected by a rod 178 and the lower ends of said arms are connected by retrat'tile springs 179 to the inner sides of the end plates 18 andv 19. The rod 178 is adapted to engage the upper rear edges of the selector levers 411 and move the lower ends of said levers rearwardly. thus withdrawing the pins 69 from openings in the perforated sheet 77 or out of contact with said sheet.

Operation: As illustrated in Fi 1, the reciprocatory

frame embodying bars

25, 25 and connecting rod 26 is in an elevated position. and I will assume that the perforated sheet of music 77 is in position for use. As the sheet of perforated paper moves in front of the tracker bars 71 and 72, the pins (35) are released by the openings or slots in the sheet of paper, that is, pins normally held by the solid portion of the sheet of paper 77 are permitted to extend through the sheet of paper when a slot or opening is encountered. The selector levers 11 are held in a releasable position by the sheet of paper 77 whereby when the lower beveled ends of the levers are released by openings in the sheet of paper and engage the

bars

71 and 72. the beveled prongs (31 of said levers Will be in the path of the beveled prongs 39 of the operating levers The downward movement of the reciprocatory frame places the retractile springs 25) under tension and carries the operating levers 3?) down 'ardly, causing the beveled prongs 39 of said operating levers to impinge the beveled prongs (34 of the selector levers 41. The selector levers 11 are held by the cushion 67 upon the rod 68 and the operating levers are caused to tilt, as best shown in Fi 14. The prongs 64 ride into the slots -10 of the operating levers, while the prongs 38 of said operating levers are in proxin'iity to the rod 08. The operating levers are gradually tilted during the movement of the reciprocatory frame and the upper ends of said levers engage the depend ing extensions 54 of the locking levers 42. The locking levers 42 are tilted. thereby re leasing the vertical extensions 51 of the key levers 43. said key levers being limited in their movement by the cushions of the rods 58 and 00. hen the key levers 4?) are tilted.the

cords

40, 158 and their connection tilt the strike levers 47, through the medium of the bell cranks 166, cords 105. couplers 103. cords 102. and guides 159. The strike levers 4T elevate the rear ends of the keys 7 through the medium of the cords 157. this movement of the keys being as though the forward ends thereof were struck with the fingers. The keys having the same connections with the hammers as the keys of an ordinary piano. said hammers, corresponding in number to the number of selector levers released. Will be actuated. The reciprocatory frame having completed its downward stroke. said frame is ele 'ated by the springs 20 previously placed under tension by a downward stroke of the reeipro catory frame, the tension of the springs being sutiicient to elevate said frame. As said frame is carried upwardly, the end 03 of the rod 20 engages the pin 91 of the arm 89. The arm 89 is raised together with the pawl 80. and this pawl engaging the ratchet wheel 85 causes the shaft 84 to partially revolve and wind the perforated sheet of paper 77 upon the roll The perforated sheet of paper is intermittently moved and during its winding movement; upon the roll 83, a rearward rotation of said roll is prevented by the pawl ST. The pawls 86 and ST remain in engagement with the 'atehet wheel 85 during the winding of the perforated sheet and are only moved out of engagement therewith when said sheet is to be wound upon the roll 78.

After the piece of music has been played. the operator elevates the handle 10S. crank 100 and cranks 741, best shown in Fig. 4, thereby moving the retaining rod 73 outwardly and turning the rod 75 whereby the lower ends of the selector levers will be moved out of engagement with the sheet of paper 77. As the cranks 74 are elevated. the rod 109 elevates the wedge 110 causing the upper end thereof to push the hinged member 112 inwardly toward the cross head 114. This movement of the hinged member shifts the ratchet wheel 118 toward the end plate 10 (see Fig. 3) placing the

clutch members

82 and 119 in engagement with each other. The wedge 110 shifts the hinged, member 112 into the path of the protruding end of the rod 31, and as the reciprocatory frame is operated. an up stroke of the frame causes the pawl 121 to revolve the ratchet wheel 118 and a down stroke of the reciprocatory frame allows the spring 111' to lower the cross head 114. whereby the pawl 120 will continue the rotation of the ratchet wheel 118. As the ratcl'iet wheel 118 is revolved. the sheet of 'iertorattal paper 77 will be rewound upon the roll 78 and then said roll can be removed from the player.

It will be noted in connection with the rewinding mechanism that the cross head 114" is cut away. as t 121 as best shown in Figs. 7 and 18 to provide clearance for the end of the rod 31. whereby the end of this red will not actuate the rewinding mechanism. except when the hinged member 112 is shifted into the path of the end of the red 31. Yhen the rewinding mechanism inactive. the cross head 11 t rests upon the pin 125. Immediately upon the wedge 110 being lowered by the elements 103. 100. 73. H and 75 being restored to their normal position. the spring 82 separates the clutch nn-mbers. thus placing the rewind mechanism in an inactive position. \Vhen the cranks H are elevated to place the rewind im-ehanism in an active position. the

cords

101 and 103 move the pawls ST and 80 out of engagement with the ratchet wheel 85. as shown in Fig. 4. therel'iy allowing the roll 5 t to unwind while the sheet of paper 77 is wound upon the roll 0%. moved out of engagement with the ratchet wheel 85 through the medium of the kicked member 101 that extends under said pawl.

The above description tr *ats of the manrer in which the releasable selector levers l1. operating levers 3 3. locking levers 42 and key levers t a actuated by a down stroke of the reeiprocatory frame 21. and said levers are restored to their normal position in the following manner. reference being had to l igs. 8. 14' and 15. As the reciprccatory frame is moved. only those seleetor levers that have been released by the sheet of 'ierforated paper are engaged by the operating levers, those selector levers held by the she t of perforated paper allow ing the operating levers to ride clear in the rear of the said selector levers. On the upstroke of the reciproeatory frame. the operating levers 33 release the locking levers and said lock ng levers are restored to their normal position by the ret-ractile springs 5:"). As the reeiprocatory frame makes a down-stroke. the prongs 30 of the operating levers 33 will ride over the prongs 0 of the selector levers 41 that are in the path of said operating levers. and the key levers l3 representing said selector levers will not be struck bv the opeating levers. F ueh is the action of all selector levers and their complementary levers that are in an The pawl 80 active positi n. that is. being used by the pins (3!) projecting in the slots or op nings of the perforated sheet of paper 7?.

Now assuming that an active selector lever is restored to its normal position up n the up stroke of the reciproeatory l'raine. then the key lever ti) associated it! said selector lever is partially restored to its normal position by the spring 1.313 of th strike lever t? pulling downwardly upon the cords that connect the strike lever ll t the key lever t l. This construction is be i shown in Fig. 16. When the key ever is partially restored to its normal position. the verti *al extension thereof engages the under side of the lccking lever t" adjacent to the notch ()n a down str of the reciprocatory frame. th prong W of the operating lever engages in the n tch lit of the key lever. thereby tilting the key lever sutli ciently to cause the upper end thereof 11' ride into the notch 52. where it is locked by the lever 4:2. in performing this opera tion. the operating lever Il is slightly tilted upon the rod Ill. and immediately up n at: upstroke of the r ciprocatory frame. the op crating lever assumes a vertical pwili'rn. whereby the prong 33 will ride in th notc 50. This notch provides sufficient clearance whereby the key lever will not be actuated until the complemental selector ever is again released.

It will be observed that the operating levers have four functions or di tinctive movements. first. that of being positioned by the selector levers: second. that of engag ing in the notches 49 of the key lever to restore said levers to their normal po-ition; third, that of engaging the locking levers to release the kev levers. and fourth. that of moving freely of all of the selector. locking and key levers. particularly during the rewinding operation of the perforated sheet of paper 77. There will be times during the rem'oduction of a piece of music. that cei tain sets of selector. operating. locking and key levers will be in operation or in active positions, while other sets of levers will be in inactive positions. This particular move ment of the various cooperating levers is somewhat similar to that described in my pending application. and reference will now be had to certain improvements that insure a more positive operation of the player.:

without resorting to a complicated construction. First, there is the expression mechanism illustrated in Figs. 1 to 16 inclusive. t

To increase the tension of the springs 13; in connection with half of the strike levers 47 and half of the keys 7, the tension board 132 is made in two parts. whereby one part can be moved independently of the other to increase the tension of one half of the strike levers 17 can be controlled for obtain-- ing" a hard or soft stroke of the keys 7. hen the wedge 134: is pulled inwardly or released wherebythc spring 117 can pull outwardly upon said wedge. one or the other of the

tension boards

131 or 132 is moved. When the lever 1 15 is moved. the pivoted plate 133 is pulled downwardly. bearing directly upon the tension board 131 and bearing upon the board 13:2 through the medium of the wedge 1233. thereby lowering both boards to produce a loud stroke of all the strike levers 4?. By holding the lever 145 and moving the lever 154. the wedge 134 can be shifted to lower the tension board 132 independently of the board 130. and by releasing the wedge 134. the lever 145 can be lowered to move the plate 135 and the tension board 131 independently of the board 132. There are simply two expressions obtained in connection with the player. both of which are controlled by the operator of the player manipulating the levers 1 15 and 154.

lteference will now be had to the retracting device shown in Figs. 3 to 11) inclusive. this device being employed for moving the elector levers upon each up stroke of the reciprocatory frame. whereby the pins (39 will be positively removed from the perforated sheet of paper 77. By moving the selector levers. it is impossible for the pins 69 to tear or injure the paper during its movement. As the rcciprocatory frame makes a down stroke. the dogs 1T1 ride over the pins 171. as shown in Fig. 11. and after the frame has completed the down stroke, the dogs 171 are located below the pins 17-1, as illustrated in Fig. 12. 'hen the reciprocattmy frame makes an up stroke, the dogs 17] engage the pins 174-. as shown in Fig. 153. tilting the arms 17? and causing the rod 178 thereof to engage the upper ends of the e ector levers 41 and shift said levers whereby the pins 69 thereof will be retractet. lnnnediately upon the reciproatory frame rea hing the limit of its up stroke. the at'liis 17.3 and the rod 179 are restored to their normal position by the swings 1T9.

To recap tulate. it will be observed that l have d vised a player embodying a selector mechani m in connection with a movable perforated sheet of paper, a series of actuating levers controlled by the selector mechanism. means for operating said levers with the same means employed for intermittently moving the perforated sheet of paper during the operation of the player and when the paper is to be rewound. Associated with these elements is an expression mechanism manually controlled and a selector retracting mechanism that is automatic in its opsprings 156 or relieve the tension of said l'eration for the purpose for which it is in springs. In this manner the stroke of the i tended.
