I UNITED STATES PATET QFFTCE,
JOHANN G. PETERSON, OF JERSEY CITY, NEVi JERSEY, AESSIGNOR TO MANHATTAN ELECTRICAL-SUPPLY COMPANY, OF JERSEY CITY, NEW JERSEY, A COBBORATION OF NEW JERSEY.
ELECTR-OMAGNET-MOUNT.
Specification of Letters Eatent.
Patented June 6, 1916.
To all whom it may concern:
Be it known that I, JonANN G. PnTnRsoN, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Electromagnet-Mounts, of which the following 1s a specification.
This invention relates to what I shall for convenience term an electro-magnet mount, the primary purpose of the invention being the provision of simple and effective means for insulating the magnet and its frame from a base, frame or other support.
The device as may be inferred is susceptible of general use, although it is of particular utility when incorporated in an electric bell.
In the drawings accompanying and forming part of the present specification I have shown in detail one convenient form of embodiment of the invention which I will fully set forth in the following description. I do not limit myself to this exact disclosure; I may depart therefrom in several respects within the scope of the invention defined by the claims following said description.
Referring to said drawings: Figure 1 is a front elevation of an electric bell involving the invention, the cover or cap for the electro-magnet being removed. Fig. 2 is a similar view of the magnet frame and base or hell frame associated together and with the other parts of the bell removed. Fig. 3 is a detail View of an insulator. Fig. 4 is a longitudinal section on the line 4t4t of Fig. 2, looking in the direction of the arrow and on a slightly larger scale.
Like characters refer to like parts throughout the several views.
As already intimated the mount is capable of advantageous use in various connections; it is shown, however, incorporated in or forming part of an electric bell.
The numeral 2 denotes a base or support which in the present case carries the bell 3, the hammer for which is denoted by l and as operated by the magnet 5. This magnet as shown isparallel with the support 2 being supported by a frame 6, the body of which is practically in the form of a fiat plate having at its ends the lateral extensions 7 and 8. The extension 7 has an outwardly projecting flange 9 to which the hammer d is suitably connected, while the extension 8 is provided with an outwardly projecting flange 10 constituting a heel iron for the magnet and to which the magnet 5 is suitably rigidly connected as by riveting.
The main or bell frame 2 and theauxiliary or magnet frame 6 are, will be ob vious, of metal, the former for instance being cast and the latter stamped from sheet stock. They are insulated from each other by an insulator as 11 of fiber or other suitable material. l fhile this insulator is shown as being in one piece and as approximately flat, at least as to its body or main portion, this may not always be necessary, although it is a desirable construction. The form of the insulator l1 practically follows that of the bell frame 6. This insulator 11 is shown as having on its rear surface bosses 12 adapted to fit somewhat closely or snugly in approximately circular recesses 18 in the bell frame 2, which provides a way for effectually preventing slip of the insulator '11. The insulator fits substantially flatwise against the front face of the frame 2 and the frame 6 in turn fits flatwise against the insulator or strip 11, the several parts being united together in some suitable manner as by rivets 14.
The bosses 12 by which the insulating strip 11 is interlocked with the bell. frame 2 are on the rear face of said strip, and as they are pressed therefrom there will be formed on the front or insulating strip the circular recesses 15 which receive the bosses 16 pressed from the magnet frame 6, so that the magnet frame is interlocked with the in sulating strip. The bossing of the rear side of the magnet frame 6 forms on the front of said frame the circular recesses 17, and in these recesses may be positioned insulating washers 18 of fiber or other suitable material, the recesses 17 properly positioning the washers. The rivets 14L to which I have already referred extend through these washers and also through perforations or holes in the recessed and loossed portions of the frame 6, insulator 11 and frame 2, the rivets being headed over the rear face of said frame 2 and also over the washers 18 so as to firmly and rigidly connect the several parts. The perforations 19 in the magnet frame 6 through which the rivets 14: extend are of greater diameter than the external diameter of the shank portions of the rivets, the Walls of the shank portions of said rivets being appreciably separated or spaced from the Walls of the perforations or holes 19 which provides a means for insulating the bodies or shanks of the rivets from the magnet frame 6, the latter as will be understood being insulated from the frame 2 by the insulator 11. The inner heads of the rivets are insulated from the frame 6 by the Washers 18.
What I claim is:
1. The combination of a support, a magnet frame, an insulating strip between the magnet frame and the support, the strip being interlocked With the support and the magnet frame being interlocked with the strip, rivets, the magnet frame, the insulating strip and the support having perforations through which the bodies of the rivets extend, the diameters of the perforations in the magnet frame being greater than the diameters of the bodies of the respective rivets to thus insulate said bodies from the Walls of said perforations in said magnet frame, and Washers around said bodies,
fitted against the magnet frame and abutted by'the inner heads of the rivets. I
2. The combination of a support having recesses, an insulating strip having bosses on one side and corresponding recesses on the other, the bosses of the insulating strip fitting the recesses of the support, a magnet frame having bosses on one side and corresponding recesses on the other, the bosses of the magnet frame fitting the recesses of the strip, the recessed portions of the several parts being perforated, rivets passing through the respective perforations and headed at their ends, the walls of the perforations in the magnet frame being spaced from the rivets, and insulating Washers around the bodies of the rivets, disposed in the recesses of the magnet frame and abutted by the inner heads of the rivets.
In testimony whereof I afiix my signature in presence of two Witnesses.
