MUSIC-SHEET-BEGULATOR THROW-OUT.

Specification of Letters Patent.

Patented June 11, 1918.

To all whom it may concern:

Be it known that I, ROBERT A. GALLY, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in MusicSheet- Regulator Throw-Outs, set forth in the annexed specification.

In applicants prior Patent #1,093,046 is the broad invention of means to alternately make effective either automatic means or manually controlled means of a web guiding device, and one particular form was therein shown. The present invention shows another desirable form for use with many styles of web guiding or automatic tracking devices, and especially so with the novel form of automatic tracking device illustrated herewith, but which tracking device per 86 is a part of a prior application #186229 filed August 14th 1917. The present application also sets out an extra feature whereby the detector fingers of the automatic device are thrown out of contact with the edges of the music during the use of the hand regulator, thereby avoiding interference and friction from the combined action of the two means at one time.

In the drawings Figure 1 is a front view of a music roll apparatus and combined automatic tracking device and hand roll regulator, the hand regulator thrown out of use, and the automatic tracking fingers contacting the two edges of the music sheet and controlling the true travel of the sheet; and in Fig. 2 is the same view with the hand roll regulator thrown into use and the automatic tracking fingers thrown out from the edges of the music sheet.

Two usual clutch spindles 1 and 2 are adapted to engage and revolve a music roll 3 on which is mounted a music sheet as 4. Two vertical detector fingers 5 and 6 are mounted on pivots 7 and 8, and have in wardly extended horizontal arms 9 and 10 which nearly meet, and at such position of adjacency cooperate with a valve seat 11 which is mounted on another horizontal arm 12, pivoted co-axially with arm 10. All these arms, 9, 10 and 12 are extended beyond these pivots 7 and 8, and on such extensions are individual counterweights 13, 14, and 15. These several weights are so arranged that when the detector fingers 5 and 6 are to contact the edges of the music sheet 4 the pressure of the detectors 5 and 6 will not be overstrong against that paper. Particular care is taken that the counterbalancing is so adjusted that the seat 11 will always follow the inner ends of the arms 9 and 10, but that either one alone of the said arms 9 or 10 will have sufficient remaining weight to always rest on the seat 11 when the other arm 9 or 10 is away from the seat 11 when the music sheet is-diverged from its central travel.

When the sheet 4 is truly central the two detectors 5, 6, and their arms 9 and 10 both maintain contact with the seat 11, thereby controlling certain ports connected to any usual pneumatic apparatus to actuate the shifting means to move the spindles 1 and 2 to the right or left to compel the central travel of the sheets whenever it diverges therefrom, and thereby thrusts one or the other of the arms 9 and 10 away from the seat 11. The intermediate parts, as pneumatics, etc., are not here shown, but are to be understood as having tubular connections from ports in the seat 11 to any suitable pneumatics, the latter having mechanical connections terminating by a rod 16 engaging a unitary means or yoke 17 similar to applicants prior Patent #1,112,061 September 29, 1914, which yoke engages the two spindles 1 and 2 and by suitable collars thereon and the spring 18 draws the two spindles together and thereby engages them with and holding the music roll 3, or any other suitable connecting and controlling means may be employed.

Whenever a music sheet is found that has its perforations cut out of center to the correct travel line, or whose edges are too badly damaged to properly control the detectors 5, 6, the hand roll regulating devices can be thrown into operation, and the detectors may also be spread apart and clear of the edges of the sheet, as in Fig. 2, as will now be explained. v

The spindle 2 runs in a regulator bearing 19 threaded co-axially therewith into a support 20. While 'in a structure without an automatic tracking device such a threaded regulator, bearing 19, would directly regulate the position of the roll 3 by the said roll being pressed against the head 21 of the said spindle 2 and that head against the end of the regulator bearing, such a construc tion would interfere with the action of an automatic tracking mechanism, which could not move the spindle 2 to the right because of the checking by its head 21 against the regulator bearing 19, wherefore the present structure has the regulator bearing-l9 of a length to clear the head 21 of the spindle 2 so that the head 21 and its spindle'2 are freeto be longitudinally moved by the automatic tracking means 17, 16, etc., as described in par. 2 of page 1.

lVhen the hand regulating is desired,-the switch or throw-out handle 22 is partly re volved with the shaft: 23 on which it is fixed asshown in Fig. 2, thereby the circumferentially tapered cam 24- has its full width part broughtaround within a groove in the collar 25 attached on spindle 2, which wide part ofthe cam 2 1- has a nice running and guidin-gfit to the groove of the collar 25, thereby compelling the collar 25and spindle 2 attached therewith, to maintain whatever position lengthwise of the spindle linethat the cam 24L andits attached shaft 23 may be set to by control of a plain guide arm 26 and hub col-larfixed with the shaft 23, and guided by a groovehin a collar 27 attached toorna part of the regulator19 and revoluble with said bearing 19 and thereby shiftablelengtlr wise of the spindle line to regulate any def siredtracking position of theroll 3 and its music sheet 4-, as shown by the dotted lines in Fig- 2 indicating the rightward position of the regulator parts, thefull lines being the leftward positionlV-hen the apparatus has the switch handle 22 set for hand regulating,-which in the present showing is with the handle 22 thrown over to the front and down, an extension or arm 28 is pressed down on the head 29 of a vertical rod, 80, which rod 30 stands over the counterweight 15 or other convenient and suitable part-of the seat arm 12, thereby depressing that outeraend of the seat arm 12 and raising these-at; 11,and thus lifting the two arms 9, 10,'and, throwing apart the two detectorarms 5, 6, so that their detector parts, clear'theiedges of the musicsheet and thus'have-the sheet free, and avoid any actuating of the automatic tracking devices against ,the setting of the spindles by the hand regulator, which actuating at suchtiine would cause great-retarding or entire stopping of the spindles from the pressure of the automatic tracking motor means against the {regulated spindle, WVhen the detectors 5, 6,,1are sospread, andatheseat 11 is in a raised p0sition,-both the arms 9, 10, are held onithesaid seats, so that theentire automatic tracking devices are outof operation, and

free for the longitudinal regulating of the spindle 2 by the hand regulator 19. A spring 3lserves to hold the-rod 30, free from the weight l5 and arm 12 when the throw-out handle 22 is in position for r the I automatic tracker devices to operate.

hen the throw-out handle 22 is set for the operation of, the automatic. tracking des vices, the narrow part of the cam. 24L is between the sides of the groove of the collar 25 so that the 'wider part of the cam may be sure to follow to position in that groove when revolved to that position by the handle .22 and the shaft, 23, but the difference in or apertures, and whether pneumatic, electric or mechanical power, or any combination of powers, as pneumatic mechanical or the, like, but what I claim as my, invention 1s:
