ELECTRIC ACCENTING DEVICE FOR PNEUMATIC MUSICAL INSTRUMENTS.
Specification of Letters Patent.
Patented Dec. 3,1912.
Application filed April it, 1911. Serial No. 621,143..
To all whom it may concern:
Be it known that we, WALTER M. DAVIS and Jusrus HA'ITEMER, citizens of the United States, residing at New York, county of New York, State of New York, and West New York, county of Union, State of New Jersey, respectively, have invented certain new and useful Improvements in Electric Accenting Devices for Pneumatic Musical.
Instruments; and we do hereby declare the following to has full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.
This invention relates to self-playing musical instruments and has for an object to provide electrically actuated means for accenting the notes of the theme or any other partof the music which it is desired to accent.
A further object of the invention is to which in turn control such accent box with electrical means for controlling the valves and means-whereby the electrical means is energized by the passing over the tracken bar of openings in the music sheet.
A further object of the invention is to provide an accent box having a primary with aconduit leading to the primary and a valve for closing the conduit also with an electro-magnet positioned to open the valve when the magnet is energized and an elec tric circuit including the magnet and contacts adapted for engagement through an opening in the music sheet as the music sheet passes over the trackerbar.
A further object of the invention is to provide improved mechanism for controlling the position of the brush relative to the trackerbar.
With these and other objects in view. the
invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed- In the drawings :Figure 1 is aview of the improved .device diagrammatically shown with the electro-magnets positioned for actuating the manual accent control. Fig. 2 is a view similar to Fig. 1 except that the electro-magnets are located at or 'near 'tge accent box and control the passage to t e primary. Fig. 3 is a perspective fragmentary view showing one of the brushes andactuating means with the brush in operating position upon the contact. Fig. A is a perspective view of one of the brushes and actuating-means in the first position of being moved from engagement with the contact. Fig. 5 is aperspective View of the brush andactuating means showing the removal of the brush from the contact completed and the brush maintained out of such engaging position.
Like characters of reference designate corresponding parts throughout the several views. 1
' As shown at Figs. 1 and 2, an accent box 10 is employed of any construction, the device as shown being only diagrammatic and illustrative of the invention. As shown, the accent box 10 is controlled by primaries 11 and 12, althbugh it is to beunderstoodthat the posit-ion and actual operation of such ent invention. Under the primaries 11 and 12, chambers 13 and 1 1 respectively are pro vided Which co-mmunicate'by means of passages 15 and 16 With valves 17 and'18.
As shown at Fig. 1, the valves 17 and 18 are carried upon levers 19 and 20 which are ordinarily controlled by manual push buttons 21 and 22. As shown at Fig. 2 the valves 17 and 18 are carried by armatures 23 and 24. In either instance the valves 17 and 18 are controlled by electroniagnets 2'5 and. 26 respectively to open communication through the passages 15 and 16 with the primaries 11 and 12 and thereby actuate the accent-ing" device.
To energize the magnets 25 and 26 a bat tery 27 is provided with wiring forming circuits extending, as easily apparent at Figs. 1 and 2, to brackets 28 and 29 extending upon opposite sides outwardly from cheek- plates 30 and 31. The brackets 28 and primaries is Wholly immaterial to the pres- 29 form a bearing for the sliding rods '32 contacts '38 and 39 preferably flush-with the face of the tracker bar/i0 but insulated therefrom by the insulatingmaterial 41.
The contacts 38 and. 39 are in circuit with the battery2? and the electro-magnets and 26, as will be easily seen.
When changing music it is desirable that the brushes 36 and '39 be removed from position' for engagement with the sheet and it -is also desirable at times tohave such' brushes removed to-prevent mechanical accentlng of the music. and to perm t manual I accenting. For these purposes the rods 32 and 33 are provided with the arms 42 and the contacts-BS and 39.
brushesv backwardly out of engagement with 43;.whichslide along the edge of the brackets ZS and 2'9 and'when the brushes are in operati've position are seated in the notches-44 and 45, "The 'arms'are held within such notches yieldingly by. means of-springs 44:"
and 45' which serve not only to hold the levers-within the notches 4A and 45 but by reason (i -their angular-position, also to hold the brush yieldingly in engagement with To remove such the contacts, the rods 32 and 33are' also provided with fingers 46 and 4:7 engaged by the hooked ends 48 and 49-of rods 50 and 51 journaled at the side 'of the cheek-plate in any approved manner as by the-blocks 52.
The rods KO-and 51 are provided respectively with arms 53. and 54 connected by, the link 55 so that both of such levers operate together inunison to simultaneously move the brushes 36 "and- 37. A link 56 is also preferably provided, connected in any approved manner with the rewind lever so that when the rewind is actuated the brushes are automatically removed. As such connection forms no part of the present invention how ever, it is not here illustrated.
It will be apparent that with the brushes 36 and 37 in engagement with the contacts '38 and 39, when an opening inqthe music sheet passes over such contact, the brushes will engage the contact and close the circuit through the battery 27 and electro-magnets 25 and 26, dependent upon whether the brush 36 or 37 is at that instant permitted to engage its contact. By the arrangement of marginal openings upon the music sheet, properly spaced, the magnets 25 and 26 are energized at the proper instant to actuate the primaries l1 and 12 to in turn actuate the accentin device which may be of any ordinary an approved construction.
With the brush located as indicated at Fig. 3-, it is apparent that such brush is in engagement with its contact. I movement of releasing'such brush from such engagement is illustrated at Fig. 4, which by reason of the peculiar shape of the hook e8, first rotates the rod 32 by depressing the finger 46 to release the lever 42 from the notch 44 and simultaneously to lift the brush 36 from engagement with the music'- This' frees the brush from contact sheet. which might injure the brush. The further rotation of the rod 50 forces the rod 32 back to the position shown at Fig. 5 whereat the" spring 46 draws the rod 32 to such position first a turning movement of the rod 32 and 2. lifting movement of the finger 34, as indicatedv at ,Fig. 4, Whereby'the brush is released from engagement with the -music sheet and trackerbar and then the brush and its carrying rod moved slidably backward to the position shown at Fig. 5' and all by the simple continued turning of the rod- 50.,
We Quinta? 1. In inpneumatic player for musical instruments, the combination of a pneumatic accenting device, of manual means for con trolling the accenting device, and electrical means controlled from the trackerbar for actuating-the manual apparatus.
2. In a pneumatic player for musical instruments, a pneumatic accent box, a conduit leading from the accent box and terminating in a port, a manual lever carrying a valve controlling the port, electrical means for actuat-ing the lever, and contacts located at the trackerbar adapted to closethe circuit through perforations in a traveling music sheet.
In testimony whereof we aflix our signa-- tures in presence of witnesses.
