Application filed .Tune 12, 1916. Serial N0. 103,085.

To allwhom t may concern:

-Be it known that I,`I*Iim\narA EREEVE, a" citizen of the United States ofAmeri'ca, residing at Brooklyn, New York, have invented a new and useful Gong Construction, of which the following is a specification.

My invention relates particularlyV to the mounting of the gong top or bell and the abutment for the striker or hammer. It is intended especially for what are known as electric bells or gongs, the striker of which is operated by electric current.

vThe main object is to provide astrong, simple and inexpensive construction for' supporting a'gong top so that it'will be held from rotation.

Another' object is to pro-vide a` durable` buffer or cushion for the hammerwhich will take up the shock of the rebound but without `itself causingv the hammer to rebound and at the same time reduce the sound of theshock to a" practicable minimum.

Figure 1 is a front view of a construction embodying the improvements of my invention, part of the gong top being broken away to illustrate the important details of construction.

Fig. 2 is a fragmentary section on the plane of the line -m of Fig. 1.

Fig. 3 is an end view of the post or support for the gong top.

Fig. 4 is a view of a fragment of the gong top showing the shape of the opening at the center.

Fig. 5 is a detail view of a washer.

The operating mechanism of any suitable type may be mounted, for instance, in the casing 10. The hammer 11 is pivoted at 12 and suitably connected by means not shown with the operating mechanism.

The gong top or bell 13 is supported by bracket 14 which has a forwardly projecting post 15. The gong top is secured to the post by means of a bolt or screw 16 whose shank passes through the hole 17 in the gong top.

in one positionfonly. This prevents anyone from putting thev gong top on wrong side up .and insures accuracy and' permanency of adjustment. Preferably the walls 21 of the pockets 2O are substantially radial so as to provide a maximum resistance' to rotation of the' gong top without developing any'cam action. I also preferably'provide a washer 22 having a central opening 23 for the shank of the screw 16 and having lateral openings even high speed drills will not last long and 1n many cases are of no use in drilling holes of a small size. It has been found practically impossible to punch such small holes in tool steel. I have found that by the construction herein shown and described it is possible'to punch the hole for the stud or fastening screw and the pockets for the pins simultaneously at small expense and at the same time provide a construction which will hold a gong top satisfactorily.

In the construction shown, the hammer is mounted beneath the gong top and normally hangs as shown in position to be propelled upwardly and outwardly to strike the inner edge of the gong top. In such a construction it is necessary to provide a stop or abutment for the hammer but the ordinary solid stop jars the mechanism and also makes considerable noise and sometimes causes a number of small vibrations which cause it to rattle and interfere with the clear tone which the gong should produce. To avoid this I have provided a simple, inexpensive but reliable cushion stop. This consists of a projection 26 at one side of the post 15 and a metallic face plate 27 riveted to it but with a layer of cushioning material 28 interposed. The parts may be riveted together as indicated at 29. With the proper cushioning material properly held between the rigid projection 26 and the face plate 27 a stop is produced which brings the hammer to rest with very little shock or sound. Preferably the cushioning material is non-vibrating, such as rubber cloth with a layer of canvas, or such as leather or a material having` similar characteristics, and the face plate is preferably somewhat soft or at least nonresilient.

l. In a construction of the character described, the combination With a supporting post and a stud carried thereby, of a hard metal gong top having a centrally punched opening for said stud and a lateral pocket extending off to one side from said central opening and formed simultaneously with the punching of said central opening and an upstanding member on the supporting post at the side of the stud on the supporting post and engaging in said lateral pocket to thereby position the gong top engaged on the stud.

2. In a construction of the character described, the combination With a supporting post and a stud carried thereby, of a hard metal gong top having a centrally punched opening therein for the stud and laterally extending pockets at opposite sides of said central opening, upstanding pins on the supporting post at opposite sides of the stud engaging in said laterally disposed pockets and projecting beyond the face of the gong top and a Washer engaged over the gong top and having a central opening for the stud and laterally disposed openings at opposite sides thereof receiving the upstanding pins to thereby tie together the outer ends of said pins.

3. In a construction of the character described, the combination of a supporting post having a lateral projection, a non-resilient metallic face plate, cushioning material rigidly clamped between said face plate and said projection, a gong top carried by said post and a hammer adapted to strike against said gong top and against said face plate.

4. The combination With a supporting post, a securing bolt on said supporting post and an upstanding projection on the supporting post on one side of said bolt, of a gong top of hard steel having punched therein a substantially centrally disposed boltreceiving opening With a co-extensive laterally ofset pocket, said gong top being secured on the post With the bolt engaged in the substantially centrally disposed opening and the upstanding projection engaged in the pocket offset to the side of the central opening.
