When the parts are 5 features of the invention. so supported, the armature 20 is located within A description of the mounting of the double contact point I! on the reed lt will be given as,
an example of one form of the invention. Referring to Fig. 2, 22 designates an aperture formed in the reed it at a point which will be alined with the fixed contact points I5 when the parts are assembled, which aperture is somewhat larger than the doubl contact point I! (as may be seen in Fig. 3). Intermediate its ends, the contact point I! has a depression formed therein which, in this instance, is in the form .of an annular peripheral groove 23. When the contact point is positioned in proper relation to the reed i8 in the assembly of the parts, the groove 23 is opposed to the margin of the aperture 22.
Interposed between the contact point and the margin of the aperture is a sleeve-like connecter 24 (see Fig. 4) which fits snugly about the contact point and within the margin of the aperture. The connecter 24 is preferably formed of 8. ourrent-conducting material which may be readily deformed or distorted under normal shop temperatures. Silver has been found to be a suitable material. If desired, an'internal edge at one end of the connecter may be beveled, as at 25, to facilitate insertion of the contact point. After the parts have been assembled as shown in Fig. 4, the outer edges of the connecter 24 are struck inwardly at an angle to the plane of the reed and to the axis of the contact point by means of'a suitable tool. By this operation the connecter is deformed so that a portion 28 thereof enters and fills the depression or groove 23 while other portions 21 are forced into a firm gripping engagement with the reed about the margin of the aperture 22. This relationship of parts -is shown in Fig.5.- a
It will be evident that a novel method of attaching contact points to resilient reeds has been produced whereby the parts are rigidly secured together withoutthe use of a heat treatment and without distortion ormachining of the contact points. Consequently, there is no distortion of the flexible reed which would produce a variation in the movements thereof, and the reed assemblies may be manufactured in quantity and with sub- ;stantial uniformity. Moreover, an excellent electrical connection between the sembLv is attained.
I claim as my invention:
1. 'The method of securing a contact point to a thin spring tempered vibratory member while maintaining substantially the original flexibility and resiliency of said member which consists in forming an aperture in the thin member without distortion thereof, locating a contact point of substantially less diameter than said aperture and having an annular groove therein within said aperture with said groove opposing the margin of parts of the assaid aperture, interposing a bushing of an easily distortable soft and current conducting material between said margin and said contact point, and distorting said bushing to turn the ends thereof over said margin and to force an intermediate part of the bushing into said groove to secure the parts firmly together, the bushing distorting force being so applied that no distortion ofthe vibratory member occurs. 7
h 2. A vibratory reed for a device of the character described which is adapted to vibrate accurately due to the absence of reed distortion and comprises the combination of a thin fiat member formed of a spring tension material of determined vibration frequency and having an aperture therein defined by a substantially undistorted margin of the member, a contact point of substantially less diameter than said aperture and extending therethrough, and a bushing in said aperture and about said point formed of a soft material which is a good electrical conductor and is capable of being easily deformed into g ipping engagement with said point and margin by the application of a force which will not distort said member so as to preserve said vibration frequency.
3. In a vibratory device, a thin, fiat reed mem ber having an aperture therein defined by a substantially undistorted margin of the member, a cylindrical contact point extending through said aperture and being of a diameter substantially less than said aperture, and a deformable connecter fashioned as a cylindrical bushing fitting snugly about said point andsubstantially occupying the space between said point and said margin, said connecter having an internal surface beveled toward one edge to facilitate reception of said point in assembling the device.
4. A vibratory reed for a device of the character described which is adapted to vibrate accurately due to the absence of substantial reed distortion comprising, in combination, a thin fiat resilient member having a determined vibration frequency, said member having an aperture therein defined by a substantially undistorted margin margin of said member defining said aperture,
and a bushing in said aperture and about said point formed of a soft material which is a good electrical conductor and is capable of being easily deformed into gripping engagement with'the side faces of said member about said margin and into the groove in said point by the application of a force which will not distort said member.
5. The method of securing a contact point to athin vibratory member. of spring tempered material while maintaining substantially the original flexibility and resiliency of said member which comprises the steps of forming an aperture in said member without distortion thereof, locating a contact pointof substantially less diameter than said aperture within said aperture and extending therethrough, intcrposing a bushing of an easily distortable .soft'and current conducting material in said apertm'e and about said point and deforming said bushing into gripping engagement with said point and margin by the application of a force which will not distort said member whereby to preserve .said vibration frequency.
