corporation of Missouri Application January 6, 1938, Serial No. 57,777
3 Claims.
'I'he object of my invention is to provide a multi-speed vibrator which is simple, durable and comparatively inexpensive to manufacture.
A further object is to provide a vibrator of I the type which can be held in the hand, and which has a vibration applicator with a means for controlling the degree` of vibration, including a control member conveniently located on the vibrator so that it can be readily controlled as l desired.
A further object is to provide a vibrator including an electro magnet and an armature responsive to energization thereof, the electro magnet having a plurality of windings and a switch 13 being provided for varying the degree of energization by energizing either part or all of the windings.
A further object is to provide an electric vibrator including'a stamping having a base portion to which a three-pole core is secured, and an armature portion terminating adjacent said poles, a winding being mounted on the center pole to provide an eiliciently operating vibrator.
With these and other objects in View my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forthpoint ed out in my claims, and illustrated in the accompanying drawing, in which:
Figure 1 is a perspective view of a multi-speed vibrator embodying my invention.
Figure 2 is a vertical sectional view on the line 2 2 of Figure l.
35 Figure 3 is a. vertical sectional View on the line 3 3 of Figure 2.
Figure 4 is a perspective view of a combined armature and core support used in my vibrator;
and
40 Figure 5 is an electro-diagrammatical view showing the connections of current supply to the vibrator windings controlled by a variable switch.
On the accompanying drawing I have used the reference numeral l0 to indicate a supporting handle. 'Ihe handle I0 has a ferrule l2 secured to an upper casing part I4. A complementary lower casing part i6 telescopes into the casing part I4, and the two are held assembled relative 50 to each other by bolts I8.
The casing portion i6 is provided with an opening 20 through which an applicator shank 22 extends from the interior to the exterior of the casing. A vibration applicator 24 is mounted 56 on the shank 22, preferably in a detachable man- (Cl. 12S-41) ner so that other applicators can be applied to the shank.
A dome-shaped cover 26 is provided on the casing member I4 and is held in contact therewith by a screw 28.
Within the casing formed by the parts i4 and I6 I provide a vibrator structure comprising a heavy sheet metal stamping A, best shown in Figure 4, a laminated core 30 and an electro-magnetic winding 32. 'I'he stamping A has an armal0 ture portion 34, abase portion 36 and a connecting portion 38. The base 36 is perforated as at 4|) for the screws i6 to extend through, spacer sleeves 42 serving to retain the base 36 against the head of the casing portion I4 when the parts 15 are assembled.
The base 36 is provided with a pair of perforated ears 44, which receive screws 46, see Figures 2 and 3, extending into the core 30. The core 30 is of laminated character, the laminations 20 being held assembled relative to each other by rivets 46.
The core 36 has a central leg 30a and a pair of end legs 30h, each of which terminates a slight distance from the armature 34. Whenever the winding 32 is energized with an alternating current, the magnetic impulses set up in the core by such energization intermittently attracts the armature, thus causing vibration of the applicator 24.
By forming the armature and the core in the shape illustrated, maximum attraction is secured, the magnetic lines of force issuing from the poles 30h entering the pole 30a, or vice versa, the armature being directly in the path of these lines. 35 The connecting portion 36 being of metal is suillciently resilient to permit vibration without the necessity of providing a hinge joint for the armature, and thus I am able to eliminate rattling and wear of such a joint, and provide a quietly operat- 40 ing vibrator.
It is quite often desirable to change the degree of vibration of a vibrator of the kind shown, and I am able to do this with the electrical hook-up shown in Figure-5. 'I'he winding 32 is provided with a center tap 32a, with which a wire 50 is connected, which extends to a contact 52. One end of the Winding is connected directly with the current supply by a wire 54, and the other end is connected by a wire 56 with a contact 58. A switch 50 60 is connected with the other current supply wire 62. The switch 60 is a single pole, double throw switch.
When minimum vibration is desired, the switch 60 is moved to position engaging the contact 68, 55
whereby the entire winding 32 is energized.
' When maximum vibration is desired, it is moved to the other position, that is, engaging the contact 52, so that only a portion of the winding is energized. A portion of the winding oiIers less impedance to the tlow of current, and accordingly a heavier current will tlow, resulting in an ampere-turn increase and thereby a greater degree of vibration.
'I'he switch 60 is suitably located with respect to the casing and handle of the vibrator, and in Figure 1 I have shown a control knob Il therefor mounted on the casing adjacent the inner end oi.' the handle. The knob 64 is accordingly in position for ready manipulation from the fo to either the high or low position, as desired.
, Although I have shown only a two position switch for high and low operation, it is obvious that other degrees of vibration can be obtained by taps in addition to the center tapl 32a, and a three or four position switch can be used if desired. The tap 32a does not necessarily need to be centrally located, but can be 4at any position desired intermediate the ends of the winding 32, depending on the relative vibration desired in the high and "low" positions.
Changes may be made in the construction and arrangement oi' the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover bymy claims, any modied forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.
I claim as my invention:
