HARRY L. BOYNTON AND ELSEE M. BOYNTGN, OF SAN FRANCISCO, CALIFORNIA.
SPRING SOUNDER.
Application filed June 1'7, 1921.
To all whom it may concern:
Be it known that we, HARRY L. BOYNTON and ELSIE ll. Bornron, citizens of the United States, and residents of the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Spring Sounders, whereof the following is a specification.
This invention relates to a musical instrument, that is an instrument, in which the musical tones are due to longitudinal vibrations from helical wire extension spring sounders, of suitable sizes, graduating in length from 2 to 27 inches, and graduating in diameter from of an inch to' of an inch wire, graduating in gage from No. 1 to No. 22 (American steel wire gage), in combination with friction wheels, sounding boards, and sound boxes.
In the accompanying one sheet of drawings We have represented enough parts of an instrument containing the invention to fully illustrate the same, and the invention may be best understood from a study of the drawings and the subjoined description thereof.
In the drawings Figure'l is a sectional elevation showing one of the helical wire extension spring sounders, the sounding boards and sound boxes, one of the friction wheels, and actuating mechanism.
Figure 2 is a diagrammatic View to show the efi'ect of the friction wheel upon the spring sounder, while engaged.
Figure 3 is a fragmentary view of the drive roller and friction wheels at right angles to Figure 1, the point of view being between the'spring sounders and the action behind friction wheels.
in the figures;-The reference numeral 1, represents one of the blocks secured to the perpendicular sound board 2, and having on, or as a part of it, the nut 3, the hook 4, to which one end of the spring sounder 5 may be attached, andthe sign post 6.
The blocks with the parts above men-- tioned, are designed to have the function of transmitting the vibrations from the springs 5 to the sound board 2 and are placed at dif ferent points on the sound board, to corre spond with the lengths of their respective springs to form a chromatic scale. Byprop erly placing these blocks, the spring sounders need no tuning after being attached.
Specification of Letters Patent.
Patented Mar. 14, 1922.
Serial No. 478,420.
The perpendicular sound board 2, extends across the entire upper part of the instrument, and constitutes a support for the sound. box 7, sound board 2, at each end engages the horizontal sound board 8, which also extends across the entire length of the instrument, thereby forming an inverted T shaped sound board. 9 is an aperture between sound board 2, and sound board 8. The end-brackets 10, are designed to serve as end blocks for the lower sound box 11 as well as for holding sound box 7 and sound board 2, in a rigid position with sound board 8. Sound box 7, is provided with an aperture 12, in its back, otherwise, is without apertures. Aperture 12 is of truncated wedge shape, and extends nearly the whole length of the box. It may be about two inches at one end and about one-half inch at the other.
Tie tail pieces 1 1 of which there is one for each of the spring sounders 5, are placed on sound board 8 over base bar 15. Screw hook 16, on the tail piece 1 1 is to hold the end of the spring sounder at that point.
Sound box 11, is formed by curved back board 17, mounted upon end brackets 10,.
and joined to sound board 8. Sound box 11, is provided with an aperture 18, nearly its full length.
The friction wheel 20 is moved to and from spring sounder 5 by a fork 21 attached to a flat spring 22 secured to base rail 23. The friction wheel is held by its trunnion engaging slots 24:, in the fork 21. When it is desired to remove a friction wheel, the fork is raised until the slots 24 free the trunnions and the wheel is then taken out and replaced as desired. This may be accomplished without deranging any of the other wheels. I
The flat spring 22, in the form of an L, holds the friction wheel in a tensioned contact upon the drive roller 25, which extends the full length of the action, and is provided with grooves 26, to guide friction wheels.
hen the pneumatic chamber 29 is inflated, the pneumatic 27 collapses, and by means of the adjustable prolong wire 28, the spring 22 and the fork 21, are thrust forward, forcing thereby the revolving friction wheel 20 against the spring sounder 5, as shown particularly in Figure 2.
The continuous rotation of the drive roller 25, in the direction indicated by the arrow, revolves the friction wheel 20, in the oppo site direction, as indicated by the arrow in Fig. 2. The friction wheel 20, parallel to spring sounder 5, has a friction band 30, of a composition which grasps the coils of the spring 5, as shown in Fig. 2. By the continuous revolving of friction wheel 20, the coils of spring sounder 5, are grasped and released in quick succession, thus setting up a longitudinal vibration along the entire length of spring sounder 5. The cushion wheel 31, gives flexibility to friction band 30, allowing same to seat itself securely upon. the drive roller 25, and acts also as an absorbent to any over vibration from the sounder.
By this means, the coils are not forced away from the grasp, until the cushion has compressed it the required amount, then the spring between the cushion wheel and the tail piece. extends as shown in Figure 2, until the tension therebetween becomes great enough to cause the spring to break away from the cushion wheel and retract to its normal position. By this means. the entire flexible spring between the tail piece 14 and the nodal rest (3, is pulsated in a longitudinal manner.
An adjustable check nut or distance button 32 is provided on the threaded prolong wire 33 of fork 21 and acts as a stop against the extension rail 34, by means of slots therein. A block 05 is fastened on the end plate 19 and acts as a rest for the bearing 36, and the guide rail 37, which extends across the action, and is fitted with a number of" pins 38. that act as guides for the forks 2.1.. I A liioring 39 through the pneumatic QT and its chest 29 [)Qll'll'lliS the free passage of the air to and from the interior of the pneumatic during operation. The adjustable prolong wire 28 extends through the hole 39. In the lower part of the pneumatic chest, is a boring 40, which acts as a conductor between the chest and the primary action, (not shown).
Having thus described our invention, and an embodiment of it. in the full. clear and exact terms required by law, and knowing that it comprises novel, useful and valuable improvements in the art to which it pertains,'we here state that we do not wish to be limited to the precise construction and arrangement of the several parts, as herein set forth, as the same may be variously moditied by a skilled mechanic without departing from the spirit of the invention.
