ELECTRIC VIBRA'IOR.

Specification of Letters Patent.

Patented Sept. 9, 1919.

Application filed June 25, 1918. Serial No. 241,799.

To all whom it may concern:

Be it known that I, RUDE STOGKINGER, a citizen of the United States, and resident of Manitowoc, in the county of Manitowoc and State of lVisconsin, have invented certain new and useful Improvements in Electric Vibrators; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to certain new and useful improvements in vibrating devices of that type shown and described in a patent issued to me December 4:, 1917, No. 1,249,236,

It is primarily an object of the present invention to provide a vibrating device of an exceedingly simple and'compact nature andwhich, due to the peculiarities of construction, grounding of the current used in its operation is prevented.

A more specific object of the invention resides in the manner of resiliently suspendlng the electro-magnet whereby upon deterioration of the spring the same may be replaced without the necessity of disassembling the magnet.

Another object of the invention resides in the manner of securing the laminae of both the armature and coil together to eliminate eddy currents being set up therein.

A further object of the invention is to provide a suitable casing in connection with a device of this character, which is adapted to carry a terminal block, and prevents foreign substances from accumulating u on the.

working parts and decreasing the e ciency of the device.

With the above and other objects in view which will appear as the description proceeds my invention resides in the novel features of construction, combination and arrangement of parts substantially as described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of this invention may be made within the scope of the claims.

In the accompanying drawing I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof in which:

Figure 1 is a sectional view of the device taken on the line of l1 of Fig. 2, and

Fig. 2 is a sectional view indicated by the line 22 of Fig. 1.

perspective view of the 6, the side arms of which are U-shaped and have secured therebetween a U-shaped laminated core 7. The core is provided with the usual winding 8. The laminae which make up the core are secured together and to the arms of the yoke 6 by non-magnetic rivets or bolts 9. Secured to the base plate 1 is an armature 10 made up of laminations held together by the non-magnetic rivets 10.

It will be seen that the core laminae 7 and the laminae of the armature are parallel. Due to this and to the fact that the U-shaped construction of the core laminae exposes a greater surface of the coil to the atmosphere over-heating which is generally the case is prevented.

Secured to the base plate is a cover or casing 11 which carries a terminal block 12. This terminal block is made of suitable insulating material and is provided with con tact members to which the coil is connected.

It will be seen that the base plate 1 is provided with a suitable work engaging lug 13 which facilitates ready attachment of the device to the pattern plate or article that itis desired to vibrate. Carried upon the bolts 14 which secure the spring 4: to the supporting'members are spacing plates 15 adapted to hold the electro-magnet centrally positioned between the supporting members.

From the foregoing description taken in connection with the drawing it will be seen that the electro-magnet is loosely mounted upon the supporting spring 4. Therefore, should the spring become deteriorated through successive use a new one can be readily inserted between the yoke 6 and laminae 7 without necessitating disassembling of the electro-magnet.

The outer laminae of the core are provided with flanged ends 7 adapted to retain a fiber or insulating plate 16 which holds the windmg 8 upon the arms of the core.

It will be readily seen that in constructing a base 1 of insulating or non-conductive.

material, the current which successively energizes the electro-magnet and causes the same to exert a series of taps upon the armature carried by the base plate, will be prevented from grounding, should the winding becomeshort-eircuited with. the casing due to defective insulation.

What I claim. as new is 1. A device of the class described comprising a non-conductive base plate, supporting members secured to the base plate, a fiat spring mounted won the supporting members, a yoke adapted to straddle said spring, a U-shaped laminated core secured within said yoke, magnetic windings surrounding said core, and a laminated armature mounted on said baseplate.

2. A device of the class described comprising a base plate, spaced supporting members secured to the base plate, a flat spring mountedon the supporting members, a laminated core carried upon said spring, spacing plates for holding the core centrally of the supporting members, and an armature secured to the base plate.

3. A device of the class described comprisi-ng a non-conductivebase plate, s )aced sup porting members secured to the base plate, a fiat spring mounted upon the supporting members, a yoke adapted to straddle said spring, a 'U-shaped laminated core secured within said yoke, magnetic windings surrounding: said core, flanges projecting from the outer laminae of the core, an insulating plate carried by said flanges for retaining the windings, and a laminated armature mounted on said base plate.v

In testimony that I claim the foregoing I have hereunto set my hand at Manitowoc, in the county of Manitowoc, and State of Wisconsin.
