WILLIAM J'. JACKMAN, OE CLEVELAND, OHIO.

MUSIC-TIMING- DEVICE.

Specification of Letters Patent.

Patented May 2, 1911.,

Application filed February 12, 1910. Serial No. 543,424.

To all whom it may concern:

Be it known that I, WILLIAM J. JACK- MAN, a citizen of the United States of America, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have in vented certain new and useful improvements in Music-Timing Devices; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in devices for determining time in music.

The object of this invention is to provide a device by means of which the relative length of the time to be given notes in music may be mechanically indicated.

My invention, therefore, consists in pro viding a device capable of giving out a series of sounds and having such an arrangement of parts. that the interval between the sounds can be arranged to correspond to the interval of time which should be between the striking of or sounding of a series of notes in a piece of music.

A further object of my invention is to provide a device of this character which will be simple in construction and accurate in operation.

My invention also consists in the features of construction and combination of parts as described in the specification, pointed out in the claims and illustrated in the accompanying drawings.

In general my device comprises a rotatable member which is provided with a series of pins which are arranged in a circle and are mounted so as to slide freely through said member so that they may be caused to project beyond either face thereof. In proximity to said pin carrying member is arranged a rotatable index or scale carrying member which is preferably provided with three index strips, either of which may be brought into the proper position by rotating the said member and the arrangement of the strips is such that when the pins on the pin carrying member are caused to project beyond the face of the pin carrying member adjacent to the index member the sa d pins will extend over the strips on said index member. A resilient finger is supported in proximity to the index member and arranged so that it will come in contact with such pins as have been caused to project over the scales on the index member and when the pin carrying member is rotated a slight clicking or tapping will be produced by the contact of such pins with the resilient finger.

Referring to the accompanying drawings Figure 1 is a top plan of my invention. Fig. 2 is a side view of the same. Fig. 3 is a section on line 38, Fig. 2. Fig. 4 is a section on line 4ct, Fig. 3. Figs. 5, 6 and 7 show the index cards or strips which are carried by the index member.

Again referring to the drawings 7 repre sents the base of my device on which are arranged two small standards 8 and 9. In bearings 10 and 11 in the standards 8 and 9 is rotatably mounted a short shaft 14. On the shaft 14 is mounted the pin carrying member which consists of a circular shaped body or flanged disk 15 which is rigidly secured to the shaft 14L so as to turn therewith. On the disk 15 near the periphery thereof are arranged a series of pins 17 so that they are free to slide in their mountings and the said pins 17 are made sufliciently long so that by sliding them through their mountin s the can be caused to ro'ect beyond either face of the said disk 15. On the shaft 14 adjacent to the disk 15 is rotatably mounted the index carrying member which comprises a circular shaped body or flanged disk 19 which is provided with a hub 20 which extends out through the bearing 10 in the standard 8 and on the outer end of said hub 20 is secured a collar 21 by means of which the hub may be rotated when'it is desired to bring the index cards or strips, hereinafter mentioned, on the index member into their proper position, as will be more fully explained. On the standard 8 is mounted a spring controlled latch 22 which is arranged to engage with the disk 19 so as to hold it against rotation when desired.

On the periphery of the disk 19 are arranged three index cards or strips 25, 26

and 27. The divisions on said index strips,

as shown in Figs. 5, 6 and 7, are practically Y the same, but the index strip 25 is used when the shortest note in the bar of music is a sixty-fourth note, the index strip 26 is used when the shortest note in the bar of music is a thirty-second note and the index strip 27 ber is such that when the pins on the pin carrying member are caused to project beyond the face of the pin carrying member adjacent to the index member the said pins will extend across the said index strips. The standard 9 is provided with a horizontally arranged arm 28 to which is se cured a resilient finger 29, the arrangement being such that when the pins 17 are shoved through the disk 15 so as to project over the index member 19 and the disk 15 rotated the said pins 17 will come in contact with the resilient finger 29 producing a clicking or tapping sound. The periphery of the disk 15 is preferably corrugated or notched and on the base 7 is mounted a spring plate 30, the free end of which is adapted to enter the notches on the disk 15 thereby normally holding the disk against rotation. On the end of the shaft 1% is ar 'anged a small wheel 31 which may be driven by a belt connected with a suitable motor, (not shown) or may be rotated by hand.

As before remarked the index strip 25 on the index member 19 is to be used when the shortest note in the bar of music is a sixtyfourth note and on this index strip the first graduation is equal to a sixty-fourth note or the distance between any two of the pins 17 on the member 15. The distance between the starting point and the second graduation is equal to a thirtysecond note being twice as long as the first graduation. The distance between the starting point and the third graduation is equal to a sixteenth note being twice as long as the second graduation. The distance between the starting point and the fourth graduation is equal to an eighth note being twice as long as the third graduation. The distance between the starting point and the fifth graduation is equal to a fourth note being twice as long as the fourth graduation. The distance between the sixth graduation and the starting point is equal to a half note being twice as long as the fifth graduation. The index strip 25 is used when the smallest note in the bar is a thirtysecond note, and the graduations on this strip represent a thirty-second note, a sixteenth note, an eighth note, a quarter note and a half note. The index strip 26 is used when the shortest note in the bar is a sixteenth note and the graduations on this strip represent a sixteenth note, an eighth note, a quarter note and a. half note.

The operation of my device will now be explained. \Vhen it is desired to determine or mechanically indicate the time to a bar or number of bars of music with my device the disk 19 is rotated on the shaft 14 bringing the required index strip in to position where it can be readily seen. The latch 22 serves to keep the said disk 19 from rotating thereby holding the index strip in the proper position. One of the pins 17 on the disk 15 is then pushed through so as to extend over the starting point of the index strip. The disk 15 is then rotated until the said extended pin is brought over the gra duation on the index strip which corresponds to the first note in the bar of music. The pin 17 which then registers with the starting point of the said index strip is then shoved out over the said starting point and the disk 15 is again rotated until the said second extended pin is brought over the graduation on the said index strip which corresponds to the second note in the bar of music and the pin which registers with the starting point of the index strip is shoved out over the starting point. The operation is repeated until a pin for each note in the bar of music is extended over the index strip. \Vhen a pin for each note in the bar or bars of music has been extended over the said index strip the disk 15 is rotated and during the rotation thereof the extended pins engage the upper end of the spring or resilient finger producing a clicking or tapping sound and the interval between the taps will be the proper interval which should be allowed between the sounding of the notes when played on an instrument.
