1 Claim.

This invention relates to stabilized suspension of an object against vibration transmittal therefrom, as the object may receive impacts.

This invention has utility when incorporated in installations adapted to establish and maintain accuracy of tone for a musical note, especially from a suspended chime tube in its resonance to impacts.

Referring to the drawing:

Fig. 1 is a front View of a tubular chime assembly embodying the invention, parts being broken away;

Fig. 2 is a side elevation of portions of the chime assembly of Fig. 1, from the left, the broken away portions being along a section approximately as viewed from the line II-II, Fig. 1;

Fig. 3 is a bottom plan view of the anchor for the suspension hook stem in an insulation disk;

Fig. 4 is a fragmentary narrow-wise View of the hook stem or strap and its connection to a chime tube; and

Fig. 5 is a detail View, in perspective, of the hook, somewhat enlarged over the showing in Fig. 4.

A base or Wall plate I (Figs. 1, 2) has a top outwardly extending ange or bracket portion 2 for supporting a lid or top 3 from which there is a shield 4 as a skirt to an open bottom 5.

In the chamber thus formed there is located on the base I, a plural coil solenoid housing box 6 (Fig. 1). The showing of the box 6 (Fig. l) is for the normal or non-energized position of the parts; that is, with no current passing thru the coils in the box 6. At this position, a compression helical spring 'I locates a position of rest for a hammer 8 as directed toward but out of contact with a minor diameter resonator tube 9. It is to be noted that this is the recover position for the hammer having non-metallic striker ends with its electromagnet core portion protruding from the coil with the non-metallic end of the hammer 8 clear of abutting contact with the tube 9.

A second helical compression spring Ill is for an additional hammer II being also a solenoid plunger and in parallel with the hammer 8. This hammer II on its end toward the tube 9 has a soft rubber tip sound deadener. An offset I2 from a bracket I3 may extend into the path of the hammer I I, thereby limiting the travel of the hammer I I to be short of striking the tube 9.

Thru slots I4 in the flange 2 are screws I5 ing leg providing an eye or slot Il. The lower side of the slot I'I has a straight horizontal seat, bearing or rail portion IS. A hook I9 is the upper end of a metal strap 20. The hook may be disposed to ride on the seat I8, in providing a hanger joint for the strap 20. A coating 2| of shellac, lacquer or plastic between the throat of the hook and the seat I8 is elTectiVe to dampen transmission oi metallic sound and avoids audible disturbance of chime operation.

Upon energizing a coil in the box 6, the hammer enveloped by such coil is quickly drawn with such speed away from its normal rest position (Fig. l) as to have resonance effecting impact with a tube 22 in parallel with the tube 9 and similarly suspended. This means that as the coil for the hammer 8 is energized, the hammer 8 strikes rst the tube 22 and then the tube 9. In the event the coil for the hammer II is energized, this hammer II strikes the tube 22, but gives forth no sound from the tube 9 on account of the rubber tip at such end, or the hold back stop I2.

A cap 23 has an upwardly iianged central throat opening thru which the strap extends. This strap end is notched to provide a pair of leaf portions 24 which may be thrust thru a central diametrically extending slot 25 in a fiber insulation disk 26. The portions 24 may then be oppositely offset or iiattened against the underside of the disk 26 in providing a key assembly and support therefor. A metal disk 21 against the underside of the disk 26 locks the offsets 24. This disk assembly is in a skirt or flange 28 integral with the

cap

2,3. An end 29 of a major resonant tube 30 is press tted in the skirt 28 toward the disks 2l, 26, completing the assembly for suspension by the strap 20. The metallic bonding from the

tubes

9, 20, may be thru silver solder 32 with the throat of the cap 23, which is centrally clear .of the strap 20 as edgewise toward the direction of hammer impact on such tubes. The hammer impacts upon the tube 22 are transmitted therefrom thru the cap 23, its skirt 28, the chime tube end 29 to the tube 30. The clearance of the strap 20 from the tube 22 and the throat of the collar or cap 23, has some yield in a clearance or throat area 33 for the ber disk Z6 relatively to the cap 23.

For symmetry of showing, a third or dummy tube 35 may be between the tube 30 and a tube 34 from the tube 9. The tube 35 has therein a wood plug 36 engaged by a strap 20 from a mounting angle brackets I6 each with a depend- 55 bracket angle I6.
