To all whom, it may concern:
lie itknown that I. FREDERICK R. (iOOL- Mama citizen of the United States. residing at- Binghamton, in the county of Bron-me and State of New York, have invented cerl tain new and useful Improvements in Autowhich the following is a specification.
piano players of that general type which are controlled by the passage of a perforated 'music sheet over a duct bridge. the primary 1 object of the invention being the provision of novel means for automatically bringing a new spool into position and removing the E old spool as soon as't-he-latter has finished playing.
" A further object of the invention is the provision of a magazine adapted to contain a number of spools, means being associated I with the magazine for bringing the various j spools successively into position for playmg, and removing them from position when 5 '-For a full understanding of the invention, reference is, to be had to the following they have finished playing.
A still further object of the invention is i the provision of a magazine for automatic piano players which may be constructed to hold either a large or small number of spools, which operates in a positive and reliable manner to move the spools through the magazine and bring'thein successively into action, and which automatically rewinds each spool while the following spoolis being played.
With these and other objects in viewythe invention consists in certain novel combinations and arrangements of the parts as will inorefullyappear as the description procoeds, the novel features thereof being pointed out in' the appended claims.
' desdription' and accompanying drawings, in
which Figure 1 IS a s de elevation of a: magazine an automatic. piano players constructed in accordance with'the'present invention, the mechanism for setting the piano player in fl- 'ope'rat-i'on and stopping the same being flshown diagrammatically Fig. 2 is a top fplanjview-ofthe'device. Fig. 8 is a longitudinal'vcrtical sectional view on the 'line I Fig; 2. Fig. iis an enlarged plan detail view of the resetting cams and the main lever of the resetting mechanism. Fig. 6 is "a detail view of one end of the shield which is employed for preventing the kicker from injuring the music sheet. Fig. 7 is a i sectional view through the outer end iof one inatic Mechanism for Piano-Players, of j of the music sheets showing the spring p 1 which is applied thereto. Fig. 8 is a detail Thepresent invention relates to automatic sectional view of the resetting mechanism,
2 the parts being shown in full lines in the ted lines in the position assumed when a new spool has just dropped into posit-ion. Fig. 9 is an enlarged sectional viewthrough the duct bridge, and Fig. 10 is an enlarged view showing the springs for preventing backward movement of the spools through the magazine.
Corresponding and like parts are re ferred to in the following description and indicated in all the views of the drawings by the same reference characters;
Referring to the drawingathe numerals 1 designate a pair of castings or plates which have a spaced and parallel relation to each other and constitute the sides of the main frame upon which the mechanism is mountedythe said plates being rigidly connected by cross bars 2. These side plates 1 of the main frame are provided u on their inner faces with corresponding on less runways 3 adapted to receive the ends of the spools 4. Each of the runways is shown as comprising a lower horizontal portionB and an upper horizontal portion 3, the said horizontal portions of the runway being connected at the rear end of the magazine by a curved portion 3, and at the forward end of the magazine by a curved portion '3 The portions 3, 3", and 3 of the runway are ffilled with the spools 4 which are moved f step by step rearwardly within theportion 3 of the guideway, around the portion 3. and forwardly upon the portion 3, the various spools being brought successively into action as they drop from the forward end of the portion 3 of the'runwayrto the forward end of the portion 3 thereof. It may here be noted that -'the spools in the upper .pdrhion 3 of the runway merely rest loosely thereon so that they can readily be removed and replaced by other spools when desired.
Referring to Fig. 3 of the drawing the spoolf l which is in position for playing rests upon supporting rolls 5, and 6, the former being fixed in position and being continuously rota-ted while the player is equivalent element herein termed a duct bridge 10, and finally drops upon an apron 11 where it rolls up loosely on itself. The
feed rolls 12 and 13 for drawing the music sheet from the spool are located under the duct bridge 10, the feed roll 12 being rigid with a. shaft 14 which is positively driven when the player is in operation, while the feed roll 13 "1s journaled upon the arms 7 and merely serves to press the music sheet 9 against the'roll 12. The duct bridge 10 is of the usual construction and is deslgned to be connected to some suitable layer mechanism such as that disclosed in atent No. 917,288 which was granted to me on April 6, 1909. This duct bridge is shown as suspended by means of a' pair of hooked hangers 15 which removably engage one of the cross bars 2. v
Referring further to Fig. 3, it will be observed that the spool 4:? which was previously played is resting upon an idler 16 and a rewinding roller 17, the top. of the said spool bei'ng'engaged by a positioning roller 18 which may be suitably weighted or otherwise caused to bear upon the spool 1 so as to hold thesame in 'contact with the rewinding roller 17. The positioning roller 18 is journaled between a pair of rearwardly extending arms 19 which are pivotally connected to the frame at 20 to admit of the positioning roller being moved up and down,
' the downward movement of the said roller a second rock shaft 25.
being limited by lips 21 which project laterally from the arms 19 and are adapted to engage ribs upon the main frame.
The rock shaft S which carries the arms 7 is'aIso provided with a crank arm 22 which is connected by a rearwardly extending link 23 to an upwardly extending arm 24 upon A coil spring 26 engages this arm 2-l and normally tends to draw the same rearwardly so as to rotate the rock shaft 8 and swing the arms 7 into the position indicated by full lines on'Fig. 8. Rigid with the second rock shaft 25 and preferably integral with the arm 24 is the resetting lever 27, the said lever being shown as extending forwardly from the rock shaft and having the end thereof extended upwardly to provide a support upon which the kicker 28 is pivotally mom ted. The forward end of the kicker 28 normally projects downwardly into the path of the spools, while the upper end thereof is provided with a roller 29 adapted toi heengaged by a cam 30.u 'ion a resetting shaft 31. This resetting shaft 31 is journaled upon the sides 1 of the main frame and is also provided with a second cam 32 adapted to engage a roller 33 upon the main lever 27. The resetting shaft 31 is normally locked against rotation with the cams in the position indicated in Fig. 5, the cam 30 being out of en agement with the roller 29 of the kicker an the forward end of the kicker being held away from the spool 4" by means of a spring 34 connecting-the kicker to the resetting lever, while the roller 33-of the lever 27 is eng ed by the steep portion 32 of the cam 32. said lever 27 is thereby held in a depressed position against the action of the spring 26, and the arm 2% swung forward so as tomove the arms 7 of the rock shaft 8 into the position indicated upon Fig. 3. For the purpose of bringing a new'spool into position, the resetting shaft is given one complete revolution. The initial movement of the resetting shaft moves the steep portion 32 of the cam 32 away from the roller 33 so that the said roller can enter the depressed or shallow portion 32 of the cam and permit the lever 27 to swing'upwardly, thereby moving the kicker 28 out of the path of the spools and also operating through the arm 24 and link 23 to rock the shaft 8 and swing the arms 7 into the position indicated by full lines' on Fig. 8. The supporting roll 6 is thereby moved away from the supporting roll 5 so as to drop the spool 1. and the feed roll 13 is moved away from the feed roll 12 so as not to obstruct the downward passage of the spool 4 A continued rotation of the shaft 31 rings the roller 33 of the resetting lever 27 into engagement with a substantially circular portion 32 of the cam 32 so as to partially depress the lever 27 and thereby swing the arms 7 forward a willcient amount so that the supporting rolls 5 and 6 will engage the next spool as soon as it is forced over upon the same. The cam 30 then engages the roller 29 of the kicker 23 and moves the rear end of the kicker upwardly. thereby causing the forward end of the kicker to engage the spool 4 and move it forcibly into the position previously occupied by the spool 4". all of the spools in the magazine being thereby moved forward one step. and that spool at the forward end of the upper portion of the runway being forced over upon the supporting rolls 5 and G. The sl-ipporting' roller 5 rotates the spool in such a direction as would wind the music sheet. thereon, and while the spool is thus rotating the hooked projection at the end of the music sheet is engaged by a resetting book 36 which was moved upwardly between the feed rolls. This resetting hook projects upwardly from a. rod 37 connecting a pair of levers 38 which extend rearwardly along opposite sides of the main frame an l ale pivotally coniaected thereto at interpoints between their ends, as indi cat'edtat; The rear ends of these levers .38 are connected by links 40 to crank arms r 41 at opposite ends of. the resetting shaft 31,
.the said crank arms being so positioned with relation to the before mentioned cams as to move the resetting hook 36 upwardly when the feed rolls are separated and the new spool'is forced into position. In order to move the nose of the resetting hook 36 forwardly and insure a proper engagement thereof with the hooked projection upon the music sheet, a spring 4-2 may be utilized, the
said spring-being secured to a cross bar 43 and bearing loosely against the back of the "hook member ash is raised. A continued ,movement of the resetting shaft 31 operates thereby produces a further rotation of therock shaft 8 so asto cause the feed roll 13 to'hold the music sheet tightly against the \feed roller 12. At, thispoint, attention may be directed to the fact that the end spool {1 upon theupper portion 3 of the runway is prevented from dropping accidentally upon the sppol l by means ofa shoulder 3 at the bottom" of the runway. When the spool is I forcedforward ly it passes readily overthis shoulder, although it is held thereby against prematurely dropping into position. It will further be observed that the resetting shaft 3l is;provided with a timing disk 44: and a gearwheel 45,,the said timing disk being formed with .a notch or opening 46 into whichone end of a slidably mounted counter,-shaft;47 normally projects. This coun- V ter-shaftfis journaled upon one of the side piecsil ofthe mainframe and a bracket 48 projecting therefrom, and a pinion 49; upon the counter-shaf t is thrown into mesh with the gear wheel whenthe counter-shaft is moved to withdraw the end thereof from the opening of the timing disk, the said pinion qbeing out of engagementbtvith the gear wheel while the end of the counter-shaft is within "the "opening of the timing. disk. A shipper lever 50 which Qhas a be ll crank for mation is pivotally mounted upon the.
bracket 48 and engages the counter-shafts? arena the same within its bearings; a spring 5i being appliedto the shipper lever for'normally holding the counter-shaft in engagement with the'open'ing of the timing U disk. gin clectl'ic switch,52 is also mount- I ed upon the bracket 48, and the switch lever gagestlie counter 'shaft 47 so that the said.
53 is formed with an'cxtension 53* which en- 7 switch is closed when the; shipper lever 50 1s moved to retract the countenshafttrom theopening of the timing disk. The eni GBJ'g'agenient' of tit e counter-shaft 'with"'the opening of the timing disk normally locks the resetting shaft 31 against rotation and holds the various members in the position indicated in Fig. 3, while when the counter shaft is withdrawn from the opening 46 of the timing disk and the pinion 4-9 thereon brought into mesh with the gear wheel free end of each of the music sheets 9 has a, spring strip 54 applied thereto, the said spring strip normally tending to assume a coiled .aposition so as to prevent the music sheets from unwinding from the spools while the spools are passing through the magazine,
and also forming a nucleus or center about which the unwound music sheet rolls as it. is drawn from the spool and dropped upon the apron 11.- The before mentioned hooked projection 35 .is preferably formed by returning the outer end of the spring strip 54:.
An electric motor 55 is util zed for open ating the piano player, and power is transmitted through the medium of the pulleys and belts 56 to a main drive shaft 57 which is provided with a gear wheel 58; A chain or belt 59 passes around this gear wheel and also engages a gear wheel 60 which is rigid with the supporting roller 5, a gear wheel 4 61 which is rigid with the countei shafti's', a gear wheel 62 which is rigid with the re winding roller 17;, and a gearwheel 63 which is rigid with the feed roll 12. Electric current is supplied to the motor 55- through the wires 64:, and a switchtiti 'is employed for opening and closing the'circu'it. I This switch is normally held in an openposition by means of a catch 66, and is fjconnected to a pneumatic 67 by means of'a rod 68'. It will also beobserv ed that wires 69- lead from opposite sides of the main switch to the auiiiliary switch 52, and that the pneumatic 67 is connectedfby a pipe 70 to a'second pneumatic '71, the said second pneumatic bemg connected by a rod 72to one end of a lever 73 which is pivoted upon one side of the magazine, the upper end of the lever being connected by a link'7-la to the shipper lever 50. 7
The various parts of the mechanism are osition bymeans of the catch 66, the spool P being in position for playing while the spool 4 is iii -positionfor being rewound. When the switch 65 is released, either 1nanually or by dropping a coin upon a pan 75v carried by the catch 66, the said switch is normally in the position indicated in Fig. 3 with the main switch 65 held in anopen closed-bysmeans of the s ring 76. The motor is then started and t e various el ments driven. by the chain 59 set in motio The" feed rolls draw the music sheet fr the.
spool 4. over the duct bridge 10 so as t turns in such a direction as to resist unrolling of the music sheet from the spool 4*,
thereby acting to produce tension in the music sheet and hold it firmly against the duct-brid e. The counter-shaft 47 is also revolved, ut merely acts as an idler, since the pinion 49 thereon is out of engagement (3. may be'carried by the arms 7.
with the gear wheel 45. As soon as the end of the music sheet is reached, an opening therein uncovers a certain duct 77 in the duct bridge and admits airinto a pipe 78 leading to the pneumatic 67. Air is then exhausted from the pneumatics 67 and 71 so as to collapse the same, and this action of the said neumatic 67 draws the switch blade 65 ack into engagement with the catch 66 so as to open the switch, while the collapsing of the pneumatic 71 swings the lever 73 so as to actuate the shipper lever 50 and pull the counter-shaft 47 out of the opening 46 of the timing disk 44. The pinion 49 upon the said counter-shaft is simultaneously brought into mesh with the.
gear wheel 45 and the auxiliary switch 52 closed. The motor 55 continues to run as long as this auxiliary switch is closed and the various arts of the machine are still driven as be ore. The motion of the coun ter-shatt 47. however, is now imparted to the resetting shaft 31 until'the said shaft has com leted one revolution, when the counter-siaft 47 again enters the opening 46 of the timing disk 44 so as to lock the; same against motion. This sliding move-' ment of the counter-shaft also serves to open the auxiliar switch 5% so as to completely shut off t e supply of electric current to the-motor 55. The single revolution of the resetting shaft 31, however, acts as has been previously described to bring a new spool in position for playing and drop the old spool down upon the rewinding roller. In order to prevent the kicker .28 from injuringthe music sheet, a guard plate 79, which is illustrated more clearly in Fig.
The machine is now ready to play the new spool as soonas the main switch 65 is again closed, and this operation will be repeated indefinitely, the various spools being forcwbstep by step around the runway and brought. successively into action. in order to prevent backward movement of the spools through the magazine, spring delenls 80 may be applied to the sides 1 of the frame sons to bear frictionally' against the ends of the spools and engage depressions 81 therein. These spring detent-s are shown more clearly in Fig. 10, and it will be observed that the spools are perfectl free to move forward when the kicker 28 is set in action, although they are held securely against any backward movement} I Having thus described the inventiomyvhat I claim as new and desire to secure byikg ters Patent, is
