PAscuccl ETAL TRIGGER MECHANISM FOR TRUMPET 2 Sheets-Sheet 2 Filed Aug. 2, 1962 away/WA g!/ '7 H 2 Z Z W Z |ill M T 5 Hl nnw /M Q W United States Patent ()fiiice I 3,ttl,itl3 Patented Dec. 15, 1964 This invention relates to the art of musical wind instru ments, and more specifically to a new trigger mechanism for a trumpet.

As is known to those skilled in the art, a trumpet is provided with three finger-operated valves. In addition, it is provided with a main tuning slide, and with tuning slides for the various finger-operated valves.- In particular, this invention is concerned with the tuning slide for the first valve. This slide is frequently extended during play in order to flat the notes produced by the first valve. Heretofore, it has been conventional practice to use a trigger mechanism operated by the thumb for extending this slide. Such operation by the thumb has imposed a very substantial tipping force on the instrument, tending to tip it away from the players mouth.

Accordingly, it is an object of this invention to provide a. superior trigger mechanism for the tuning slide for the first valve of a trumpet or the like.

it is another object of this invention to provide a trigger mechanism for the first valve slide of a trumpet or the like which does not tend to displace the trumpet in any manner.

Still another object of this invention is to provide a trigger mechanism for the tuning slide of the first valve of a trumpet or the like which is operable by any of two or three fingers of the hand that holds the instrument.

Other and further objects of the present invention will be apparent from the following description when taken in connection with the accompanying drawings wherein:

l is a side view of a trumpet incorporating the present invention;

PEG. 2 is a horizontal sectional view on an enlarged scale taken along the line 2--2 in FIG. 1;

FIG. 3 is an enlarged side view of a fragment of the trumpet;

FIG. dis a horizontal sectional view on an enlarged scale taken substantially along the line 4-4 in FIG. 3 showing the first valve tuning slide in its normal retracted position;

FIG. 5 is a view similar to FIG. 4 showing the slide in extended position;

FIG. 6 is a vertical sectional view on an enlarged scale taken substantially along the line;66 in PEG. 1;

PEG. 7 is a vertical detail view partially in section as taken substantially along the line "7-4 in FIG. 2 and on an enlarged scale, and v I PEG. 8 is. an enlarged detail view partially in section taken substantially along the line 8-3 in FIG. 7.

Referring now in greater particularity to the figures, and first to FIG. 1, there will be seen a trumpet identified generally by the numeral it). The trumpet shown is a standard 3-,, trumpet, although it will be understood that the invention hereinafter to be described is equally applicable to trumpets other keys, to comets, and to other wind instruments in which a slide must be moved somewhat from time to time during playing for tuning. The trumpet is mainly of conventional construction, including the mouthpiece 12;, leader pipe 314, and main tuning slide 16. The main leader pipe extends to the body 18 of the instrument, wherein the first, second and third valves, espectively identified by numerals El), 22 and 24 are provided. The instrument, as is usual, is terminated by a bell zid. There is a tuning slide 238 for the'third valve 24 which is controlled by a ring 30 connected to a shank 52 respectively held by a set screw in a fitting 34 on the top of the slide 28. Conveniently, the second finger of the left hand extends through the ring 36, as shown in FIGS. 2 and 3.

The second valve 22 is provided with a tuning slide 36 having a pair of protuberances or horns 33 engageable by the fingers for adjustment. Normally, this slide does not have to be operated during playing, but remains in a preset position. I

Finally, the first valve 2t is provided with a tuning slide 49. The tuning slide itself is of conventional con struction, including upper and lower outer tubesdZ and 44. Upper and lower inner tubes 46 are slidably received in the outer tubes and 44, and are interconnected by a bight 48. The bight 48 is of somewhat larger outside diameter than the inner tubes 46', although the internal diameter is constant. Thus, the outside diameter of the bight is substantially identical with the outside diameter of the

tubes

42 and 44.

It is at this point that the instrument departs from conventional construction. A trigger mechanism identified generally by the numeral 56 is provided. A pair of curved posts 52 is ElfilXCCl to the side of the first valve in vertically spaced relation. These posts extend out toward the second valve tuning slide 36, but curve slightly away therefrom, as best seen in PEG. 2. A pin 83 (FIG. 7) extends between these posts and pivotally receives a generally T-shaped lever 54. The shape of the lever is best seen in FIGS. 2, 4 and 5. The cross member 58 of the T-shaped lever is pivoted at one end between the posts 52 and extends between the upper and lower

outer tubes

42 and 44, and has pivotally connected at the outer end thereof a connecting rod 56. The connecting rod is pivotally connected to the cross member 58 of the T-shaped lever by means of a clevis 6t and bearing screw 62. The connecting rod is provided at the opposite end thereor" with another clevis 6d, and this is connected by means of a bearing screw 66 to a post 63 extending from the side of the bight 48 of the tuning slide 4%.

The stem or shank 7d of the T-shaped lever 54- is connected to the cross member 58 relatively toward the end thereof which is pivotally mounted between the posts 52. The stem it? initially is substantially perpendicular to the cross member $8, but curves away from the valves 20, 2-2, extending between the posts 52. Thereafter, the shank is bifurcated. At this point, the shank 7G is provided with upper and

lower branches

72 and 74, respectively lying above and below the adjacent portion of body tubing '76. The branches and their extremities extend parallel to the shank 7d, and both are provided with cork or the like pads 78 for engagement with the third valve 24 upon manipulation of the lever 50. The upper branch '72 is provided with a plateau it having a roller 82 thereon, and the lower branch is provided with a plateau 84 having a roller $6 thereon.

Reference now should be had particularly to FIGS. 6 and 7 wherein the mounting of the lever 54 is shown. The end of the cross member of the lever is apertured to receive the pin 83 extending between the posts 52, the cross member 58 being centrally disposed thereon. The lever is held'in the central position by the helical portions Q6 of a biasing spring Q2 having an interconnecting central bight portion 94 straddling the cross member 58 of the lever and lying on the opposite side thereof from the stem 7d. Arms 96 extend from the outer ends ofthc helical portions as, and are provided with hook-like ends 98 engaging theqsides of the posts 52. The spring force is such as to try to bring the bight 94 and the hooks 98 together, whereby the lever is biased in a clockwise direction asseen from above. This causes the lever to pull onthe connecting rod 56, whereby to holdthe tuning slide ll) in fully closed or retracted position. The plateaus 8t and 84 are spaced outwardly away from the valves and the body of the instrument, as in FIG. 4.

The normal method of holding the instrument is in the left hand, with the palm on the left side of the valves, and the thumb extending around the front of the first valve, as shown in FIG. 3. The first finger wraps around the third valve, and the second finger is received in the ring 30, with the third and fourth fingers also wrapped around the third valve below the horizontal tubular portions of the body. As readily will be seen in FlGS. 2 and 3, this brings the index finger into proximity with ti o plateau 8b, and the third finger into proximity with the plateau 84, whereby either or both of these fingers may be pressed against the respective plateaus to depress them toward the third valve 24, thereby pivoting the lever in a counter-clockwise direction, and pushing on the connecting rod St? to extend the tuning slide as. Upon release of such finger pressure, the spring 92 returns the lever, and hence the slide to the initial rest position. The third valve tuning slide 23 is manipulated by the second finger of the left hand, as will be evident.

Although the great majority of trumpet players hold the trumpet in the left hand, in the manner just described, there are a few who for one reason or another hold the trumpet in the right hand. As will be appreciated, the trigger mechanism comprising the lever 54, etc. could with little or no modification be placed on the left side of the instrument to be operated by the right hand of a trumpet player holding the instrument in his right hand. As will be recognized, when an instrument is held in the left hand, the valves are operated by the right hand.

it has been found in practice that the natural squeezing motion with the index finger and the third and fourth fingers depresses the plateaus and operates the trigger mechanism with no tendency whatsoever to displace the trumpet. This will readily be understood when it is considered that such a squeezing force is normally used to hold the trumpet anyway. Hence, the mechanism works much more simply and with less or no conscious eifort on the part of the trumpet player, while retaining substantially one hundred percent reliability.

Although a specific example of the invention has been shown and describedfor illustrative purposes, it will be understood that various changes may occur to those skilled in the art and will be understood as forming a part of the present invention insofar as they fall Within the spirit and scope of the appended claims.
