REED FCR MUSICAL lNSTRUMENTS.

SPECIFICATION i'orming part of Letters Patent No. 351,049, dated October 19,1886.

Application filed April El, 1880.

To all whom, it may concern:

Be it known that I, ANDREW H. HAMMOND, a citizen of the United States, residing at \Vorcester, in the county of XVorcester and State of Massachusetts, have invented certain new and useful Improvements in Metallic Feeds for Musical Instruments; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

My invention relates to metallic reeds used in musical instruments; and it consists in certain novel features of construction of the reedplate at the point where the base end or head of the tongue is secured to said plate, as will be hereinafter fully described, and the nature thereofindicated by the claims.

Referring to the drawings, Figure l represents on an enlarged scale a central longitudinal section or" one of my improved reeds, taken on line x a", Fig. 2. Fig. 2 is a top or plan view of one of myimprovcd reeds. Fig. 3 is plan view of a reed-plate of my improved construction, the reed-tongue shown in Fig. 2 being left oil. Fig. at is a cross-section on line 9 3 Fig. 2, looking in the direction of arrow (1, same figure. Fig. 5 represents a cen tral longitudinal section of one of the reeds high in the scale, in which the tongue has a head or widened. base end, showing a modification of my invention, taken on line 5 s, Fig. (3. Fig. 6 is a plan view of the reed shown in section. in Fig. 5. Fig. 7 is a plan view of the reed-plate shown in. Fig. 6, the reed-tongue being left off, and Fig. 8 is a crossseetion on line it In, Fig. 6, looking in the direction of arrow 1), same figure.

In metallic reeds for musical instruments it is very desirable, and almost absolutely necessary, in order to obtain a clear and pure tone from the reed, that the base end or head of the vibrating tongue be secured to the reedplate in such amanner as to prevent anyjarring of the tongue upon the recd-plate or any vibrations of the edges of the base end of the tongue on the reed-plate, and to accomplish this result is the object of my invention. Heretofore the EICCOlllpllSllnlBlll] of this result Serial No. 199,600. (No model.)

a very slight depression in the top surface of the reed-plate at the point where the base end of the tongue is secured thereto, extending back from the rear of the slot in which the free end of thetonguc vibrates, of substantially the same width as the width of said slot as far as or beyond the point where the rivet nearest the slot enters to secure the tongue to the plate. This depression is slightly below the plane surface of the reed-plate, and is made slightly tapering or gradually sloping from. its rear part toward the rear end of the slot in which the free end of the reed-tongue vibrates, and said depression is made in the top surface of the reed-plate and extends back as far as or beyond the point where therivet nearest the slot in the reed-plate enters the plate, as be fore stated. I prefer to make this depression in the reed-plate by pressure with a tool properly constructed for the purpose, for by making it in this manner by pressing down the metal I do not weaken the stock, but rather make it stronger at this point; but I donot limit myself to making the depression by pressure, for, if preferred, it may be made by a suitable milling or cutting tool.

In the accompanying drawings I have shown in Figs. 1, 2, 3, and l a reed of my improved construction of the lower part of the scale of reeds, in which the reed-tongues are of the same width throughout, and do not have an enlarged base end or head, as is generally the casein reeds of the highest scale, as shown in Figs. 5, (i, 7, and

I will first describe the manner of construction of the reed-plate when a reed-tongue of the same width throughout is user. In the drawings the part marked A is the reedplate, provided with a slot, 13, in the usual manner, for the free end of the tongue 0 to vibrate in. D D are rivets for securing the tongue Oto the reed-plate. In this instance said rivets are punched up out of the plate A to extend through holesin the base end'of the tongue 0, and are headed down upon the tongue in any usual and well-known manner. The plate A has a depression, a, formed therein upon its upper surface, at the rear of the slot B, extending back from the rear end of said slot as far as or beyond the point where the first rivet, D, enters the plate A. The sides 0 of said depression 0 extend down or are made a little deeper that the central portion, 0, and also in this instance extend back farther, as far as the line of the second rivet, D, or there about, while the central part, 0, only extends back as far as the first rivet, D. The depression 0 is made slightly tapering or sloping from its rear part toward the rear end of the slot B, and is of the same width as said slot. It may be made by pressure, the metal being depressed by means of a suitable tool, or it may be made by a milling or cutting tool, the metal being removed. \Vhen the tongue G is riveted to the reed-plate A, having the de pression c therein, above described, the tongue does not come in contact with the plate between the point at which it is riveted to the plate by the rivet D and the slot B. The central part, h, of the base end of the tongue 0 is bound down firmly upon and held in close contact with the plane surface iof the plate A by the rivet D, just at the rear or back of the central portion,c", of the depression a in said plate; but the edges k, which are away'from the direct action of the rivet D, do not come in contact with plate A at any point between the line of said rivet D and the slot B, and the side depressions, 0, extending back to the line of the second rivet, D, or thereabout, prevent the edges from coming in contact with the plate Aback of the first rivet, D, as far as theline of the second rivet, D, or thereabout. It will thus be readily seen that any jarring or vibrations of the edges of the head or base end of the tongue 0 upon the reed-plateAare prevented, for the only point of contact between the tongue 0 and the plate A (except back of a point where any jarring or vibrations couldpossibly occur) is just where the rivet D binds and holds the centralpart, h, of the tongue 0 down upon and in close contact with the flat surface of the reedplate A. p

In Figs. 5, 6, 7, and 8 of the drawings I have shown my invention applied to a reed of the higher part of the scale of reeds, the tongues of which are necessarily so narrow that they require a head or widened base end at the point where they are attached to the reed plate. These tongues may be attached to the reedplate by means of one or two rivets. I have shown two rivets in the drawings.

In order to apply my invention to reeds in which the reed-tongues have heads or widened base ends, it is necessary, in order to accomplish the result desired, to slightly depress the having a slot, F, therein for the tongue G to vibrate in. Said tongue G has a head or widened base end, G, which is secured to the plate E, in this instance by means of two riv- A' depression, 0, in the top surface of the plate E corresponds to the depression a in the plate A, before described. It is formed or made in the same manner; but the portion immediately around the first rivet, H, is very slightly depressed, so that said port-ion will be a Very little below the plane surface of the reed-plate, as clearly shown in Figs. 6 and 7. By reason of the portion immediately around the first rivet, H, in the reed-plate E being slightly depressed below the plane surface of the reed-plate, as above described, the central portion, (1, of the head G of the tongue G will be drawn down a very little below the plane of the edges d of the head G in the process of riveting the tongue G to the plate E, thus I causing the edges (1 to bind more tightly and be held in closer contact with the plane surface of the plate E. In this mannerto wit, by making the plate E with the depression 0 therein, as described-that is, having the por-' tion immediately around the rivet nearest the slot F slightly depressed below the plane surface of the plate EI am enabled to hold the edges of the head of the tongue G and those parts which are away from the direct action of the rivet H in closer contact with the plate E, and thus prevent any jarring or vibrations of the edges of the head of the tongue upon the reed-plate to interfere with the clear and pure tone of the reed.

Having thus described my improvements in metallic reeds for musical instruments,what I claim as new, and desire to secure by Letters Patent, is p 1. As an improved article of manufacture, a metallic reed-plate having a depression upon its upper surface, and extending back from the rear end of the slot, in which the free end of the reed-tongue vibrates as far as or beyond the rivet nearest the said slot, said depression being slightly below the plane surface of the reed-plate, substantially as and for the purpose stated.

2. As an improved article of manufacture, a

metallic reed-plate having a depression in its of the reed-plate, and extending back from the rear end of the slot, in whichthe free end of the reed-tongue vibrates, the central portion of said depression extending back as far as the upper surface slightly below the plane surface rivet nearest the said slot, and the side por- 'tions of said depression beyond the line of said rivet, substantially as set forth.

3. As an improved article of manufacture, a metallic reed-plate having a depression therein upon its upper surface extending back from the rear end of the slot in which the free end of the reed-tongue vibrates beyond the line of the rivet nearest said slot, the portion immediately around said rivet being slightly de pressed below the plane surface of the reedplate, substantially as set forth.

i. A metallic reed-plate, A, having the de pression 0 upon its upper surface extending back from the rear end of the slot B, with the side portions, 0', extending back farther than the central portion, 0, for the purpose stated, substantially as set forth.

5. The combination, with the reed-plate A, having the depression 0 therein upon its upper surface, the side portions, 0, extending back farther than the central portion, C, of

the reed-tongue B, and rivets D D, substantially as set forth.

6. A metallic reedplate, E, having a depression, c, therein upon its upper surface, extending back from the rear end of the slot F to a point beyond the line where the rivet nearest the slotF enters the reed-tongue to secure the same in place upon the reed-
