PATENT OFFICE:

MERRITT GALLY, OF NEW' YORK, N Y

ORGAN-REED,

SPECIFECA'ION Application filed April 27, 1385.

To all whom it may conccr:

Be it known that I, MERRITT GALLY, re siding at New York city, in the eounty of New York and State of New Yorlghave invented certain new and useful Improvements in Organ-Rceds of which the following is a specification reference being had therein to the aceonpanying drawings.

In the accompanying drawings, Figure l is a plan View of the reed-bloek in several modifications, showing the opening in the block in several diil'erent shapes for reeeiving plates of various forms. Fig. 2 is a plan of the plate in several nodifications. Fig. 3 shows the reed in plan and in section, and its application to reed-cell and reedpipe; and Fig. 4 shows the reed in plan and section, the plan represent` ing a portion of the reed-block cut away or formed with a slim butt for the purpose of saving metal in the manufacture.

In my patent for improvement in organreeds, Ne. 3l4,234, dated March 24, 1885, I broadly claimed the combination, with a reed-bloek having a branching slot, of a reedtongue having prongs eorresponding with the branches in the slot, as described. In the present case I show a Construction peculiarl y adapted to dcsirable forms of vibrators, which operate in connection with a reed-block having a branehing slot and other desirable forms, as the ease may require. The greatcr part of the tone of a reed is produced by that part of the rced-tongue most distant from its point ot' attachment to the reed-block. That part of the reed-tongue nearer the point of attachnent acts simply as a spring to produce the vibrations hy reaetion against the pressure of air upon the vibratory extremity.

In Fig. 1, A A represent reed-bloeks having branching slots near the front end of the block to receive plates of branching form to correspond with the slots. This plate forms the part of the reed-tongue which beats the air and produces the tone, and has the advantage of cuttiug the air around its entire boundaryline. As the spring portion of the tongue is not enployed to produee the tone by breaking the air, it is uunecessary to slot the recdblock to receive it. I therefore attach the spring to the plate at one end and to the recdblock at the other, as shown byff', Fig. 3, removing the spring sufficientl y from the face formim; part of Letters Patent No. 3443143, dated Jane 29, 1886.

of the block to prevent contact with the block of its vibrating portion. By this means I avoid the laber of fitting any portion of the tongue to the slot in the reed-block, except that which produees the tone, and secure to this portionits greatest extent of boundaryline. This eonstruetion is not only applicable to other forms of branehing plates, as A or other desirable forms, but also to disks as A or rectangular plates, as A or other angu- ]ar forms as dcsired to produee different et feels. The disk d, Fig. 2, may be attaehed to the spring-bar of the reed at its center or at a point on the nodal line of the disk be tween its center and eircuinferenee, as at s, or at any other suitable point on the face of the disk, according to the oifect to be produced when the plates are thin enough to have vibrations independent of the vibration of the springbar.

In Fig. 3 the springj' is shown as raised on a thick Washer, through which the rivet passes which holds the spring to the reed-block, and a separating-picce is also shown between the disk and the spring. This is to prevent the spring from strikin g the face of the rccd-block. This is also aeeonplished at f' by oii'setting the ends of the spring, as shown.

XVhen eonsiderable width of reed-block is required for the opening in which the platc is to vibrate, I save metal in the Construction of the block by cntting away a portion from such part oi' the body as can be removed without inj ury to the perfeetness of the reed completed.

In A', Fig. l, the central portion of the body is punched out, leaving the entire boundary edge to be held in the groove to which it is fitted in the instrument.= Sonewhat more material is saved in the form A, and still more in A A and AK The matter of cntting away the body portion of the block to save inaterial is also applicable to branching` reeds, in which the reed-tongue is fornicd of one piece of metal.

In Fig. 3 the application of the rced to a reed-pipe is shown. The pipe` G is of that kind which has an opening at its base for the emission of a part of the tone of the reed. This opening serves in this case also another purpose, as it provides for the vibration of the tongucf. The reed, however, may be placed upright in the pipo and entirely inelosed, as

gles to the plane of its face, and therefore in order to have the throw of the reed sufficiently great to give the proper results the reed requires a great tension of air. .lt is sometimes desirable to avoid this, and when such is the Io ,cas e I bevel the edges of the tongue or plate, I asshown at a*, Fig. 4. This Construction prodnces a reed which will operate under very low tension with good results.

I am aware that in patent to Briggs, No.

1 15,921, of October 21, 1866, a reed is described consisting of a ring and a thin disk forming a vibrator Suspended within said ring by a stem extending to a spring above the vibrator. In such Construction the spring was not attaehed to the reed-block, but to a support on the reed-board, and it was necessary to maintain the vibrator eentrally in the ring by g a rod extending down through a hole in a bar below the vibrator. I make use of no such 2 3 device, and make no claim thereto.

That I claim as my invention is- 1. An organ-reed block having a perforation therethrough, a tongue-plate oonforming to the Outline of said perforation, and a separate stem narrower than the plate, attaehed to the plate and to the block, said plate and stern together forming the reed-tongue,substantially as described.

2. An organ-reed block havinga perforation therethrough, a plateconforming to the Outline of said perforation, and a separate spring-stem narrower than said plate, attached to the plate and to the reed-block, and ofi'set to lie above the plane of the block, all combined as stated.

3. In combination with a reed-block having a broad body portion provided with an aperture, in which the reed-tongue plays, and a narrow extension for the attachment of the tongue, a reed-tongue having its Vibrating portion corresponding to the slot in the block, and having a narrow spring-extension attached to the narrow extension of the block, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
