MUSICAL DEVICE.

Specification of Letters Patent.

Application filed March 6, 1913. Serial No. 752,294.

To all whom it may concern:

Be it known that I, EDWIN S. MAYLAND, a citizen of the United States, residing at Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Musical Devices, of which the following is a clear, full, and exact description.

This invention is an improvementin musical devices, and is concerned especially with mechanism for supporting and sounding suspended tubular'bells or chimes, the object being to secure an advantageous and spaceeconomizing relation of the parts, to provide an electro-magnetic hammer for striking the bell which is capable of operating.

efficaciously with a small amount of current, and to secure a unit construction wherein the bell and its associated parts are carried by the magnet frame.

A particular object is to so construct and arrange the hammer and its electr c-magnet as to secure great sensitiveness of the hammer by virtue of its mounting and to enable it to execute a long stroke, without a wide initial air gap, thereby deriving the force of the blow largely frommomentum with corresponding economy of current.

Another object is to provide the device with a steady bar, advantageously disposed for checking the movement of the suspended skilled in the art as the specification vpro-.

coeds.

In the accompanying drawings: Figure 1 is a side-elevation of my improved invention for striking a blow on a tubular bell. Fig. 2 is a face view of Fig. 1. Fig. 3 is a partial sectional detail of the striking hammer showing the removable hammer body. Fig. 4 is. a back plan view of the supporting bracket. 7

The tubular bell or'chime is designated 13, the same being suspended by means of a cord 12, which passes through a ertures in its upper portion. It is operate by means of an electro-magnet 5, arranged to act upon a hammer 3, which I mount in a pendulous manner above and to one side of the tube,

the magnet being horizontal and more or less directly over the upper end of the tube.

A magnet frame 1 constitutes the support for all the parts, and preferably consists of a plate or casting having screw-hoieears 7 and 8 whereby it may be applied by means of screws 9 to the face of a primary sup port 10. Projecting outward from the frame is a trunnion bar or hammer support 2, which is suitably bifurcated at the end to receive the swinging bar of the hammer 3, which is fulcrumed on the support by the pivot points 4. The horizontal magnet 5 is port 2 forms part of the magnetic circuit,

which is adapted to be closed by the bar of the hammer, forming the armature. The core of the magnet is desirably surrounded by a felt pad 7?, which prevents the armature sticking to the magnet and thus insures va prompt return of the hammer away from the tube.

The hammer head 28, the relation of which to the tube is such that the latter is 'struck at the top, is fixed to the end of a flat spring 27 which extends upward along the inner face of the hammer bar 2, and is united thereto by rivets 26, somewhat below the magnet. By this construction the hammer is caused to strike its blow by an over-throw movement, after the rigid hammer or armature bar has been brought to rest against the magnet, and immediately to spring backward, thus avoiding interference with the vibrations of the tube. A felt sleeve 21, held in place by a screw 22, interposes a cushioned or deadened contact surface between the spring 27 and bar. 3, and thus avoids any interfering metallic noise. The striking portion is preferably a hard leather piece 30, which projects through an opening in a retaining collar 29.

Normally the hammer stands at an inclination, as shown in Fig. 1, being held yieldingly in this position by suitable means, such as a weight 24 secured to an upward extension 23 of the hammer bar over the hammer support 2, whereon it contacts with a rubber buffer 25 serving as a cushioned abutment. After the forward stroke and the deenergizing of the magnet, the weight restores the hammer to normal position.

I Un the lower portion of the frame 1 are two projections, preferably carrying hooks 10, forming laterally spaced supports on which thecord 12 is hung. -The said lower Fatentedltipr. 2o, iota. I

portion of are fr ar'riealso bears 'a-forwat'dlyprojecting arm 14:, on the outer end of WlllCll is fixed a steady bar 16. The latter extends "downward at one side of the hammer and 5 is bent or directed sidewise so that its ex tremity, bearing a felt pad 17 is brought i interposition-itmcontact-w-ith the upper -por-' tion of the tube, below and at the s'arne side as the hammer. This device serves to check 10 undue movement of the tube, but= does not affect the tone, because the hammer strikes the, tube away from the pad. The steady device is of particularvalue' when repeated Qblow's are to be struck, since without it the chime might be set swinging, so as to be struck either when moving away or toward the hammer, thereby causingloss of power or impairment of the sound, or both.

'Bindingposts l7 and 18 on the lower part. of the frame are connected with the. ends of the magnet coil, and alsoreceive the ends of. wires fleadingfrom a suitable source of curit possible to operate the device with but small consumptionof current. At the' same time the action from the standpoint of the, musical effect to be secured is especially suitable, "As already explained, the resilient connectlon of the hammer head with the hammer bar removes the striker Timinediately from"thei tube, and as soon as the circuit s opened the hammer that: the flat' spring 27 carrying the striker extends for a substantial distance along the inner 'or forward face of the hammer bar 3, being free to swingforward from the latter but otherwiserigidly sustained thereby, The

striker mounted onth'e projectingend of the spring istloseto the end ofthe bar ln, a comparatively'limber spring can this'way been'xployed, which will absorb little powr at the end of the stroke, I vibrations the striker are avoided.
