REED-ORGAN ATTACH M'ENT.

SPECIFICATION forming part of Letters Patent No. 294,621, dated March 4-, 1884:.

Application filed June 11, 1883.

(No model.)

. to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a-rear view; Fig. 2, a plan view; Fig. 3, an end view; Fig. l, a sectional side view in the position of the stop drawn to bring the attachment into action with the keys of the instrument; Fig. 5, the same with the stop closed to take the attachment out of action with the keys.

This invention relates to an improvement in the cymbal or bell attachment for reed-organs. This attachment consists of a series of bells arranged with intermediate mechanism, so as to be operated by the keys, and such as seen in Letters Patent of the Unitedistates granted to John R. Lomas, dated March 2, 1875, No. 160,448. In that invention the apparatus is made as a part of the structure of the organ that is to say, is constructed with the organ as a part of it, the same as the reed-boards, wind-chests, &c.and is not an independent structure made so that it may be introduced or not, as occasion requires; nor can it be made as an independent article by one manufacturer having the right to so manufacture and sell to organ-makers generally, to be introduced into the organ by such manufacturers.

The object of my invention is principally to make the bell. attachment an independent structure, so that it may become an article of itself; and it consists in the construction as hereinafter described, and more particularly recited in the claims. s

A B represent the two uprights, connected by a horizontal bar, 0. On a rod between these two uprights, and ahovethe cross-bar,

the bells D are arranged, the arrangement of the bells upon the rod being substantially the same as that in the Lomas patent before re ferred to. From the uprights at each side an arm, E, extends forward toward the keys, but

below. Between these two. arms, and at their forward end, a rocker board, F, is hinged, as at a, the board extending forward from the pivot-line, and from the rocker an arm, H, extends rearward and beneath a slide, 1, at one end of the frame. This slide is connected to a lever, L, hung to the upright, as at b, and from which lever connection is made to the stop, so that by pulling outthe stop or pushing it in a corresponding vibratory movement is given to the lever L, and consequently a corresponding horizontal sliding movement to the slide I. The forward-end of the slide I is turned downward, and stands in front of acorresponding projection on the arm H, as seen in Fig. In that position the rocker-board is down and the stop closed. be pulled out, the turned-down end of the slide I will pass onto the upward projection onthe arm H and force that arm downward, as seen in Fig. l, and correspondingly turn up the forward edge of the rocker-board. \Vhen the stop is forced inward, the slide will return to the position seen in Fig. 5 and permit the.

rocker-board to drop.

Now, if the stop M are the bell-hammers, hung to the crosspiece 0, as at d, the hammer being forward of the pivot,'but the tail of the hammer eXtending to the rear. From the tail of the hammers arod, 6, extends up, carrying a check, f, which rests upon the bell when the hammer is down. Near the forward edge of the rocker-board the hammer-levers N are hung, as at h, the shorter arm of the lever extending beyond the edge of the board, and the longer arm extending rearward beneath the correspondinghammer, as seen in Figs. 4c and 5, and so that when one hammer-lever is depressed, as seen in broken lines, Fig. 4, it will throw the hammer upward and give to it a momentum which will cause it to strike the bell. As the hammer rises the check or damper is withdrawn from the bell. This completes the apparatus. It is placed in the organ, as seen in Fig. 4, the uprights secured firmly and directly to the sound-board, and so that the forwarder shorter'arm of the hammer-levers will pass beneath the respective keys, 1? representing one of such keys. Upon the under side of the key a stud, Z, is inserted. It may be simply a screw, which,

when the stop is in, will not reach the forward arm of the hannner-levers, as seen in Fig. 5; but when the stop is drawn, as seen in Fig. 4-, then the studs on the respective keys will. strike the corresponding levers and sound. the bell. 3y making this bell. attachment as an independent structure I am enabled to produce it as an article of manufacture, and furnish it complete to organ-makers, who have only to set it upon the sound-board and firmly secure it thereon, so that it becomes as permanent as if it were built a part of the organ, and generally no change is necessary in the construction of the organ further than to insert the studs 1, these studs being in rear of the usual valve-pins, S.

To adjust the board 1* which carries the levers so as to bring them into the proper position, I arrange an adjusting-screw, m, over the slide I, and by which the forward end of that slide may be depressed or raised, according to the variation of the board required.

It will be understood that the bearing-points between the several points are insulated that is, protected by felt-to prevent noise in the action of the lovers.

I am aware that independent frames sup porting bells have been applied in organs; but such frames have been arranged within the organ-case so as to swing toward or from the key-board, for the purpose of making engagement with the keys. Such swinging arrangein ent of the frame lacks the firmness and rigid ity necessary to the perfect working of the bells. I do not therefore claim, broadly, an independent frame supporting bellsarranged for application to a reed-organ, the essential feature of my invention being that the frame shall, when introduced into the organ, be a stationary part of it, and that the frame shall carry mechanism movable independent of the frame to bring the hammers into engagement with the keys or to disengage them therefrom.

I claim 1. The combination of the frame constructed for fixed arrangement within the organ-case, the series of bells D, hinged hammers Ill, rocker-board 1*, hung in said frame, levers N, hung upon said roeker-board, one arm extending forward into a position to stand beneath the corresponding key of the organ, the other arm extending rearward to its corresponding hammerlever, and the stop mechanism, snbstair tially such as described, in connection with said rocker-board, all arranged within and as a part of said frame, and whereby said rocker-board may be turned to bring the forward armof the levers N into a position to be acted upon by the respective keys, substantially as and for the purpose described, said frame, bells, roeker-board, hammers, and levers coustitnting a structure independent of the organ itself.

The combination of the bells 1), hinged hammers M, corres 'ionding keys, the hinged board l carrying intermediate levers, N, the stop-slide I, and adjusting-screw m, substair tially as and for the purpose described.
