Speciscation of Letters Patent.

TaaZZ whom if may concern Be it known that I, ROBERT Horn-JONES, a subject of the King of England, and residing at North Tonawanda, in the oountyoi" Niagara and State of New York, have 1nvented new and useful Improvements in Tuning Devices for Reed-Organ Pipes, of which the following is a specification.

This invention relates to the devices employed for" tuning the tongues of organ pipes. The device now generally used for this purpose consists of a sti-called tuning wire passing through the block which carries the eschalot and having its lower portion doubled upon itself to 'forni an arm or linger which bears against the tace of the tongue and is raised or lowered for tuning the tongue by adjusting the tuning wire in the block. This wire extends some distance below the block, givinv it considerable elasticity, and owing to the trictional resistance between its linger and the tongue, the bodyportion of the wire below the block is sprung or deflected away from the esclialot more or less when adjusted upwardly and toward the eschalot when adjusted downwardly, in adjusting the wire, vthis deiiecti-on continues until the resulting tension overcomes the frictional resistance of the linger when the lower portion of the wire recoils and causes' the free end of the nager to jump along the tace of the tongue to a greater or less ein tent. Instead of promptly and positively following the vertical adjustments ot the tuning wire, the nger is thus shifted to an excessive and uncertain extent, rendering it exceedingly difficult to tune the tongue accurately and requiring repeated tapping or adjustment of the wire for this purpose. But the most serious objection to said tuning def vice is that the inger does not reliably re main in adjusted position and often. shifts out of place, because the body of the tuning wire is usually under greater or less tension after effecting the adjustment.

It is the object of my invention to oven come these objections by simple and inerpensive means.

In the accompanyin drawings: Figure l is a vertical section o? an organ pipe provided with niyimproved tuning device. Fig. 2 is a perspective view of the tuning device and associated parts.

Similar' letters of reference indicate bor responding parts in both figures.

A indicates the body of the organ pipe; B

the eschalot; l; the tongue; C the block in which the eschalotis secured by any suitable means, and D the boot in the. upper end of which the block is inserted.

E indicates the body or shank of the verticallyadjustable tuning wire having the customary arm or finger El terminating in a transverse bar f; which bears against the face of the tongue. The tuning Wire is provided at its upper end with the usual lip or lateral bend el adapted to be tapped by a suitable tool for adjusting the Wire, and its body-.portion passes through a longitudinal opening of the block C. In order to prevent the above-described lateral` detiection of the portion of the timing wire below the block, l provide therefor a rigid guide bracket or support which, while allowing the wire to be freely adjusted up and down in the block, eifectually holdsits lower portion against springing, thus compelling the linger El to partake promptly and positively in slight and nice adjustments of the tuning wire and permitting ready and accurate tuning of the tongue, and also reliably retaining it in adjusted position.

'In the preferred construction shown in the drawings, the wireguiding or supporting device consists of a tube F secured in a longitudinal opening of the block C and extending a suitable distance below the block, preferably nearly to the lower end of the straight portion of the shank E. The portion oic the wire extending below the block is thus guided as rigidly as the portion within the block. As shown, the bore of the tube l" is preferably ot' the proper diameter to snugly fit the tuning i claim as my invention:

l. A reed organ pipe,comprising a tongue, a tuning wire having a shank and a member arranged at the free end of the shank and bearing against said tongue, and means for holding that portion of the shank adjacent to said member against deilection.

2. A reed organ pipe, comprising an eschalet, avblock supporting the saine, a tongue a tuning-wire having'a linger which bears against the tongue, the body of the tuning` wire being adjustable in said block, and a Patented May 13, 1913.

and extending below the same to :i point opposite the free portion of the tongue, and 15 a tuning-Wire having its body portion ndjustably arranged lin said tube and provided at its lower endI with a finger bearing against the tongue. Y,

Witness my hand this 2d day of December, 20 1910.

ROBERT HOPE-JONES.
