SAXOPHONE VALVE.

Application filed July 19,

This invention relates to improvements in saxophone valves and has as its general object to provide a valve which will be substantially unaffected by the accumulation of moisture and which will therefore be proof against leaking, the valve being so constructed that it will at all times remain in a dry state and maintain its original contour, thus insuring a perfect fitting of the valve to its opening, in the operation of the valve.

Another object of the invention is to provide, in a saxophone valve, novel means for effecting ventilation of the pad of the valve so as to prevent the accumulation or condensation of moisture in the pad.

Another object of the invention is to pro vide, in a saxophone valve, a pad of novel construction, and to so mount the pad as to provide for Ventilation thereof.

Another object of the invention is to pro vide, in a saxophone valve, a pad which will embody means, cooperating with the cup of the valve, for effectually preventing displacement of the pad and at the same time permit of ready removal of the pad and the substitution of a new pad or the repair of the pad removed.

While the accompanying drawings and the description which is to follow, constitute a disclosure of the preferred embodiment of the invention, it will be understood that various changes may be made within the scope of what is claimed. 7

In the drawings the pad cup of the key 1s indicated in general by the numeral 1, and the pad is indicated in general by the numeral 2. The pad cup 1 comprises the usual circular body portion 3 and depending, annular, circumscribing flange 4 which projects from the under side of the body portion 3 and within which the pad 2 is seated.

The pad 2 comprises a disk 5 which is preferably of circular contour and of some metal, such as aluminum, which will be proof against rusting, and this disk is formed with a plurality of openings indicated by the numeral 6. These openings provide for passage of air to the body of the pad, in a manner which will presently be explained. As shown in Figure 2 of the drawings, the openings 6 are arranged in two or more annular series concentric to one another and the openings are preferably staggered so as to provide for a uniform circulation of air which passes through these openings. The pad 2 further comprises a tiller 7 which preferably consists of a number of super-imposed disks 8 of felt or other soft and pliable material which is likewise capable of absorbing moisture and which is also of a character to insure of quick drying of any moisture, or any accumulating thereon. These disks are arranged in marginal registration, and the pad is completed by a covering 9 which is applied over the surface of the lowermost disk'S of the filler and marginally disposed snugly about the registering peripheries of the disks, the covering 9 being of such diameter, in blank form, that the marginal portion thereof may be directed inwardly and disposed fiat, as indicated by the numeral 10, against the upper side of the uppermost disk 8 and against the under side of the disk 5 at the periphery of the latter, the overturned marginal portion 10 of the covering 9 being united to the under side of the said disk 5 in any suitable manner as, for example, by the use of a suitable adhesive. The covering 9 of the pad is preferably of kid, and preferably the covering is securely held assembled with the filler disk assemblage 7 through the medium of stitches 11 which are passed through the lower side of the cover 9 and through the overturned marginal portion 10 of said cover, the stitches passing, of course, through the marginal portions of the assembled disks 8.

The pad 2 may be held Within the open under side of the key pad cup 1 in any suitable' manner as, "for example, by forming the inner sioe or surface of the flanged with screw threads 12 which'may beet such crosssectional contour as to admitof the pad being threaded into the said underside of the pad cup 1 and retained in place by the automafic conformation of the'rim portion of the cover 9 to the shape of the screw threads shown in Fi 3 of the drawings,

being understood, however, that any means may be employed for holding the pad in' place,-so long as the means willp'erinit of reinoval'or" the pad.

ln order that the pad may be suitaoly ventilated soas to provide for quick-evaporation of any moisture that inightbe te )0- rib-r l l *1" l t ii 4: iaiiiyvccpcsnec upon o e pat, ne a of the pad cup l oithe valveis formed, piet erably, at diametrically oppos with slots 13 WlllCll extend:c1rcumrerentmlly ofthe flange for a greater or less distance and provide narrow air passages throu h which air may enter the pad cup 1 hetvvt n the portion 3 thereof and the upper side of the disk 5, the pad being so arranged within the flange l-"as to be supported with the disk 5 in somewhat spaced relation to the body portion 3' 0t thep'ad cup: lt-will be ap parent atthis point that the overturned marginal portion d0 of the cover 9 extends only a shortdistance inwardly from the periphery of the uppermost disk 8 01 thehller 7 land terniinatesyin fact, at the outer sides of the outer series of openings 6, so that the uppermost disk 8 1s spaced below the disk 5 thus providing an airspace between said 7 V disk '8 and said disk 5 and thus permitting (in i the tree circulation ofair in the "the invention contemplates a valve phones of such construction that the pad space by wayoi' the openings 6.

From the foregoing it will be evident that for saxothereof Willbe at all hullQS ventilated thus maintaining the pad in a dry condition and providing for rapid evaporation of any moisture which might temporarily condense upon the surface of the paid. Therefore, the

V pad will maintain its original contour'and condition and consequentlywill at all times effectually-co-act with these ting surface above the opening in respect to which the valve is mounted, .rthus overcom ngthe disadvantages which are presented bypads and opposite the notch and therefore very close mute,

and a pad-supported by the flange usage in its side wall in communication to the periphery of the path. The means pad from thetvalve, comprises a handle 16 which 1s provided at one end with a stud '17 which is of such dimensions and contour to adapt. it to be fitted at its extremity into the notch lithe peripheral portion of the pad 2 being slightly deflected by engaging the stud 17 there-against and movingthe stud inwardlyrso to permit of depr 'n of this portion of the; pad and engagement of the end of the stud in the notch 14, wi ere upon the device, as may be seen, may be em ployed substantially. in the manner of asurface of the pad. 1
