MAGNETO.
Specification of ietters Patent.
Patented J an. 23,1912.
Application filed May 5, 1910. Serial No. 559,530.
To all whom it may concern: I
Be it known that LSHERMXN L. KELLY, a citizen of the United States, residing at South Bend, in the county of flit. Joseph and State of Indiana, have invented certain new and useful Improvements in Magnetos, of which the following is a specification.
This invention relates to certain new and useful improvements in magnetos and it has for its objects among others to provide a simple and cheap, yet durable construction. whereby the entire magneto may be quickly and easily put together without the employment of a screw or bolt or like fastening and at the same time insure a dust and water-tight protection to the working parts. such as the armature, commutator and brushes. To this end I provide a frame or inclosing casing in two parts held in close contact by screw caps or the like at the ends. The assembling frame is formed of non-uiagnlctic metal and the armature chamber is rendered water-proof. The construction is such that the U-shaped magnets when forced into place serve not only to bind the pole pieces in their proper relation to the armature, but aid also to hold the frame pieces together.
()thcr objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, forrgi a part of this specification, and in which Figure 1 is a substantially central longitudinal section through a device embodying my present improvement. Fig. 2 is a substantially central vertical cross section.
- Fig. 3 is a top plan partly in section. Fig.
4 is a cross section of the brush-holding chamber. Fig. 5 is a perspective view of one of the halves of the frame or casing.
Like numerals of reference indicate like parts throughout the several views.
Referring to the drawings, as the frame is made in two like parts, a description of one will sutfice for both. As seen in Fig. 5, each portion 1 of such frame is formed of preferably cast non-magnetic metal having rabbeted edges 2 and 3 adapted to overlap, as seen in Fig. 2, so as to form-a strong tight joint and extensions Land 5 at the ends which are exteriorly screws threaded, as seen at 6 and forming chambers 7 for the reception of the ball bearing rings 8 for the shaft 9 of the armature. These extensions are designed to receive screw-threaded'caps 10. as seen in Figs. 1 and 3, and when the two sections of the frame or casing are properly abutted and these caps screwed on. the entire machine is held together in operative condition. The cap rings 10 are provided with milled peripheries, as seen in Fig. 3, for an obvious purpose.
The side of each half or portion 1 is cut away, as shown at 11 in Fig. 5, and pro vided with ribs 12. The pole pieces 13 are fitted into the spaces thus formed. as seen clearly in Fig. .2, and the U magnets 14 and 15 are fitted or forced down on the outside of the pole pieces, thus binding the latter into their proper relation to the armature, as seen in Fig. 2. and also serve to aid in holding the frame pieces 11 together.
At one end of the two sections there is formed a chamber 16 within which runs the conunntator 17. This chamber is provided on each side with a recess 18 for the reception of an insulating plug 15) which holds thebrush holder 20 and one end ,21 of.:\ spring '22. whose other end 23 catches the brush 14. as seen best in Fig. 4, and forces it into constant engagement with the commutator 17, as will be fully understood upon reference to Fig. 4. The holder is preferably a brass tube slitted, as shown, for the passage of the end of the spring.
-Vhen the parts are assembled, a light coat of white lead or other analogous niaterial is run along the joining edges of the various parts and the armature chamber is thus rendered waterproof. The only opening is where the armature shaft passes through the cap 10, but as the chamber covered by this cap 1s designed to be filled with, a semi-solid lubricating material, this opening is rendered practically dust and water-proof.
It is to be understood that the ends of each part of the frame or casing is provided with a semi-circular recess 25 for the reception of the armature shaft.
Modifications in details may be resorted to without departing from the spirit of the invention or sacrificing any of its advanta. es.
Vhat is claimed as new is 1. A magneto casing in sections with threaded extensions and rabbeted edges, and
threaded cups engaging said extensions to hold the np-tions together.
2. A nmgiuo easing in ,seetions with threaded extensions and rubbeted edges, and threaded caps engaging said PXTPILSIHIIF to hold the sections together, said exten sions having chambers for the reception of ball bearing rings.
3. A magneto easing formed of sections having semi-eylindricul extensions at 0111" end, and caps adapted to inclose said sections and hold the sections together.
4. A magneto easing formed of sections having semi-cylindrieal extensions at ca ch am, said extensions forming hail-hearing receiving chambers, and caps adapted to 1n- ("lose aid extensions and hold the sections together.
5. A nmgneto easing formed of sections em'h having semiwylindrie'al extensions at eueh end and provided with an internal longitudinal rib which terms an abutment I for the pole piece, nmgnets for binding the pole pieces in plane, and caps adapted to int'lose mid extensions and hold them tot gether.
In testimony whereof I ntiix my signature in presence of two witnesses.
