Description

ith-ritmi tapes SiMEoN TAYLOR, or WORCESTER, MASSACHUSETTS.
Laim Paten: No. 95,536, dated october' 5, 1869.
IMPROVEMENT IN ORGAN S. AND MBLODEONS.
The Schedule referred to in these Letters Patent and making part of the same.
Know all 'man by these presents That I, Simson TAYLOR, of the city and county of Worcester, and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Organs and Melodeons, and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a planview of so much of an instrument as is necessary to illustrate my .present improvements;
Figure 2 represents a section on lineA B, figfl, of
-a port-ion of the parts shown in iig. 1;
Figure 3 represents a section on line C D,'showin'g the device for opening the rear vstop-valve; and A Figure 4 represents a section on line E F, showing the device for opening the front stop-valve.
To enable those skilled in thev art to which my inrention belongs, topmake and use tl1e-same',I will proreed to describe it more in detail.
The nature of my invention consists- First,` in the combination, with the ends ofthe con necting or coupling-levers, of Vvertical slotted key and valve-rods, as hereafter explained.
Second, in the combination, with the stop-valvesof peculiarly-constructed operating-levels, as will'be hereafter explained. f
l u the drawingsv A Av', B B represent keys, secured to the key-frame in the common way. v
The -kcy A" rests upon the key and valve-rod a, the lower part'of which rod is fitted in a guide-hole in proper frame-work below the key, while 'its lower endA A rests upon the upper part -of one of the valves, b,r which are kept closetLby wire springs in the'usual manner.
The upper end of the key and valve-rod a is `enlarged, as shown at c, and a. slot is made through such enlargement for the reception ofthe end of the coupling-lever E, as fully indicated' tin iig. 2 ofthe drawings.
The opposite endet' thc coupling-lever E ishinged or pivoted at d to the coupler-bar F, which is fastened to the arms ff, the front ends otwhich are hinged `to the key-frame at the points g g, (see'dotted lines, iig. 1,) whereby the coupler-bar F can be elevated or depressed by means ot a slide-piece arranged under the rear key, supporting piece. G, and which slide-piece is operated by the crank H.
'.lhe crunk H may be connected with operating-devices, arranged wit-hin easy and convenient reach either of the peri'brmcs hand or foot, for the purpose of enabling the performer to employ at will the coupled octave, as hereafter explained.
From the top of the coupling-lever E projects the screw-rap h, which 'can be adjusted so as to iit properly under the key A, which is provided with the usual valve-rod or pitman for opening the valve below it.
From the foregoing description, it will be seen that when the performer depresses the key A, key A', which is an octave above, will, in like manner, be depressed, thereby increasing the volume of tone.
The performer, by simply operating the crank H, 'can-so depress the coupling-bar F and rear ends of the coupling-levers E as to cause the screw-cap 'h to be dropped so low as not to be reached or struck by the key A, when it is depressed, and consequently key A would not, under 'such circumstances, be sounded, unless directly acted upon by the operatoiis fingers.
Having described the mode of coupling two keys an octave apart, it will be understood that any desired number of keys of one octave may becoupled inthe same manner to the'corresponding keys of the octave above or below.
In the drawings, the key B is shown coupled to the key B', in the same manner.
In lieu of making the coupling-levers E of wood, they may be made of met-al and cast in truss-form, to secure lightness with strength.
The lower ends of the draw stop-levers M and M are made with inclinedprojections, 2 3. Y
The projection 2, when lever. M is drawn forward, presses against a frictionfroll, 4, combined with the jointed arms or levers I and J, and consequently forces them both forward, thereby opening the valve K, while, when lever M is drawn forward, 4its projection, 3, strikes over the friction-roll 5, ,combined with the jointed arms or levers I and J, and draws said levers back, thereby opening the valve N, as indicated in red lines,'iig. 4.
It `will be seen that the stop-valves K and N are operated by my present improved mechanism with less fm'ctiou than by the mechanism recently patented by me, besides the present arrangement isless expensive 'and not so liable to get out of order. l
What I claim as my invention, and desire to secure j by Letters Patent, is'- 1. The combination, with the hinged `donpler-bar F, I
ofthe crank H and coupling-lever E, said parts being constructed and arranged substantially as and for the purposes set forth. y 2. The combination, with the coupling-lever E, of the upright slotted key-rods af, substantially as and for the purposes set forth.
3. The construction and arrangement of' the drawstop valve-levers'M M and their respective hinged arms or levers I and J, provided with the projections 2 and 3, substantially as and for the purposes set forth.
