HARTWELL R. MOORE, OF ERIE, PENNSYLVANIA.

IMPROVEMENT IN REED-ORGAN ATTACHMENTS.

- Specification forming part of Letters Patent No. 171,527, dated December 28, 1875; application filed May 8, 1875.

To all whom it may concern:

Be it known that I, HARTWELL R. Moonn, of Erie, in the county of Erie and State of Pennsylvania, have invented a certain new and improved action for operating an auxiliary musical attachment to reed and pipe organs, of which the following is a full and complete description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a side view of a section of the instrument. Fig. 2 is a plan view. Fig. 3is a view of the rear side. Fig. 4. is a view of the front side. Fig. 5 is a transverse vertical section. Figs. 6 and 7 are detached sections.

Like letters of reference refer to like parts in the several views.

The nature of this invention relates to a de vice for operating the reeds of an auxiliary musical attachment to a cabinet-organ, said device being operated by the keys of the organ, and whereby the attachment is played in concert therewith.

The construction and operation of the device are substantially as follows. Only so much of the organ and the attachment referred to is given as will show the application and operation of the invention.

In the drawing, A may represent the body of a cabinet-organ; B, a section of the manual or keys; 0, the rods whereby the reed-valves (not shown) are operated, all of which is or may be constructed the same as cabinet-organs in ordinary use, or substantially so. On

' the rear side of this organ is arranged the auxiliary musical attachment referred to, and which consists of a plate, D, Figs. 1 and 2, secured to the top of a sounding-box, E, of which it forms the cover. To said plate are attached the reeds F. Three only are shown, whereas in practice full octaves are used, and as many as compose the manual of the organ, and are played conjointly therewith, on manipulating the keys of theorgan, by means of the following device: G, Fig. 5, is a vertical slide, the upper end of which is held in the cross-piece H, whereas the foot or lower end enters the floor of the case or frame. In said slide is cut a slot, wherein is pivoted, at a, a lever, I, Fig. 5. Projecting from one end of the lever is a point, I). The projection of said point is so far as to extend over the end of the reed F when the position of the lever is such as shown in said Fig. 5. The end a of the lever extends back over the adjustable stud c, and under the adjustable pendant d, depend ing from the cross-piece H. To top of the slide G is loosely attached one end of an arm, J. The opposite end of the arm rests upon the shifter K, Figs. 3 and 5, whereby the arms are lifted up and continued in contact with the pendant 6, depending from the key B, or are lowered therefrom, for a purpose hereinafter shown.

The practical operation of the above-described device is as follows: The operator, fingering the keys of the organ, and. at the same time, desirous of playing the attachment above described in concert therewith, can do so by turning the shifter K, by means of the knob L, to the position shown in Figs. 3 and 5. This will lift the ends of the arms J, and bring the upper side in contact with the pendant e, as will be seen in said Fig. 5. On depressing the keys B of the organ, the end of the arms J, resting on the top of the vertical slides G, will bc'forced downward together with said slides. As the slides descend the points I) will strike the ends of the reeds F, causing them to vibrate at the same time that the reeds of the organ are vibrated by the action of the keys upon them in the ordinary way. To prevent the points I) from touching the ends of the reeds F on the as cent of the slides Gr, caused by the springs M, the points are drawn back from the reeds F by the end of the levers I striking upon the studs 0, which prevents the end a of the lever from further descent, while the pointed end continues downward, and at the same time recoding from the reeds in consequence of the arrest, in its descent, of the end a. The position of the levers, in respect to the reeds F, when the points have passed below them, is as shown in Fig. 6, in which it will be seen that the lever has been vibrated. This positionit maintains until the points have ascended above the reeds by the upward movement of the slides, caused by the springs M referred to. The moment that the points have passed the ends of the reeds they are projected forward by the pendant d, which pushes down the end a, and, as a consequence, projects forward the pointed side or end, thereby bringing the points again over the reeds, as shown in Fig. 5. The downward movement of the slide again brings the points upon the ends of the reeds and vibrates them, but is instantly withdrawn therefrom by the contact of the end a upon the stud c, to cause the points to ascend without touching the reeds.

It will be observed that the moment the points strike the ends of the reeds they begin to recede therefrom; hence they slip from the reeds, not only in consequence of the deflec' tion of the reeds, but also fromthe receding of the points.

By this peculiar action of the lever I the auxiliary musical attachment. is cooperated with the organ, thus playing the two instruments at once by the manipulation of the organ-keys. Should it be undesirable to play the two instruments at once the attachment can be detached therefrom by the shifter K, which, on being turned to the position shown in Fig. 7, will drop the arms J resting thereon so far that the pendants 0 will not reach thein on depressing the keys B. The organ can then be played alone.

In placing the auxiliary musical attachment on the top of a sounding-box, E, a more full and stronger voicing of the instrument can be obtained than if used without such box, as is ordinarily done.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The vibratory lever I, pivoted in the vertical slide G, and provided with point b, in combination with stud c, pendant d, reed F, and spring M, substantially as and for the purpose set forth.

2. The musical attachment for reed-organs herein described, consisting of pendants e d, levers I J, slide G, point 1), spring M, reed F, and sound-box E, all combined and arranged to operate substantially as described.
