SOUND-RE LATOR; FOR AUDIBLE sicrlxmiis. H

Application filed February 9, 1918. Serial N s-. 216,160.

To all whom it, may concern: Be it known that I, WILLIAM KnINE, a citizen of the United States, residing at WVaynesboro, in the county of Augusta and State of Vir inia, have invented certain new and useful mprovements in Sound-Regulators for Audible Signals, of which the folv lowing is a specification.

The present invention relates to mprovements in sound regulators for audible signals and particularly constructed and adapted for regulating or modulating the intensity of the sound of a telephone call bell. i e

It is generally the object of my invention to produce a sound regulating dev ce simple in point of construction and operation.

The more particular object is the construction of a device of the character indi-- cated which admits of readyregulation to produce uniform sound effects ofdesired pitch or quality. I

With this end in view, the nvention consists principally in the provision of means on a hammer orother element for striking a sound producing device for varlously modulating or otherwise difi'erently affect ing the sound of the sound producing device. This and other structural characterlstlcs forming a part of the invention will be hereafter more fully described and particularly pointed out in the appended claims.

In the drawings, in which similar reference characters indicate like parts.

Figure 1 is a top plan view of a telephone 'call bell box with a part of my improve' ment; 7

Fig. 2 is a vertical sectional view online IIII in Fig. 1; 1

Fig. 3 is a verticalsectional view on line IIIIII in Fig. 2 and Fig. 4 a perspective view of invention detached from the surrounding parts.

Referring to Figs. 1,2 and 3, 10 is the usual call bell box which houses the well known electro-magnet 11, the specific construction of which is not'material for the purposes of my invention. p

12, 12 represents the usual form of bells mounted on the top of the box 10. Through a slot 13 in the top of thebox extends a hammer centrally located between the bells as is customary. The head 14 of the hammer is provided with a plurality of striking faces 15, 16 and 17 of different tone producing quality. These different faces may be conveniently formed by boring'out portions at dlametrically opposite sections of the head 14, and inserting pieces of different material, such as wood, felt, leather, etc. In

Fig. 4, the inserts l6 and 17 represent for the sake of illustration, pieces of wood and felt, respectively, while the portion 15 is a metallic surface. WVhileI prefer to form the striking faces in the manner indicated,

there is considerable latitude in carrying out the idea involved.

From the head 14 extends a stem 18 downwardly into a sleeve 20 formedto embrace the stem. The sleeve is preferably provided with lateral flanges 21, 21 parallel in proximity to one another, and by means of screws 22 and nuts 23 these fianges may be clamped together to'any desired extent, to 1 7 fri'ctionally embrace and tightly engage the stem18." I

The lower end of the sleeve 20 is designed lower portion of sleeve 20. From this con; struction and arrangement said stem 18 with its heador hammer section 14, not only, is

pivoted to have a vibratory 'movement but It is merely necessaryto out earsnr emee Patented Ja os, 1920. l

is also adapted to be rotated through-a small angle.

Intermediate its ends a block 28 may be inserted-in this slot and connected to the stem 18. The block 28 is so shaped that the stem 18 may be turned thesleeve may be I slotted as indicated bythe numeral 27, and

through a limited angle relatively to the sleeve 20, bytheouter projections 25 of block 28 striking against the opposite and outside faces of the lateral flanges 21 adj acent to the slot 27 in the-sleeve 20.

From the head 14 extends upwardly a stem portion 30; To this stem portion may be connected by screw threads or otherwise, a knurled head 31 provided with a pointer 32.

' A housing 33 of sheet metal or other suitable material is attached to the top of the I box 10, as by screws 34. This housing has a slot' 35 through which the head 31 passes and on its outer surface the housing carries the indicia S, M, and L, to cooperate with I 20 faces 17 strikethe'bells 12 and a soft sound the pointer 32 to indicate the position of the hammer relatively to the sleeve 20 we thereby the ositionof the striking surfaces 15, 16 and 1 relatively to the bells 12. A

hood 37 is hinged on 'thehousing 33 and has fingers'38 engaging the opposite side of the housingtohold" and supportthe hood in closed position and thereby protect the head 31 and pointer 32 from injuryor disturbing their adjusted position.

The operation is-obvious. When it is desiredto obtain aloud ring, the head 31 isturned until thepointer 32 stands over L.

In thisposition the opposite metallic faces l5-are in striking position adjacent bells 12. By turning the head until the pointer 32 stands over the'letter M, the wooden faces 16, are brought into striking position and a medium sound is produced, and When the pointer 32 stands over the letter S, the. felt is roduced, v s

' Vhile in the different striking faces are used, it is obvious that alarger number may be used. Wood, felt and leather are merely referred to as. someof the materials available forvthe pur' .poses- .of the. invention; Other materials may be employed With equally good effect.- I
