UNITED. STATES JOHN LEWIS MILTON, OF LOUISVILLE, KENTUCKY.
Application filed January 12, 1921. Serial no. 436,740.
To all whom it may concern:
Be it known that I, JOHN LEWIS MrrrroN, a citizen of the United States of America, residing in Louisville, in the county ;of Jefferson and State of Kentucky, have invented certain new and useful Improvementi'sjin Magnetos, of which theg fo'llowing is a speci fication. reference being had'to the'a-ccoin panying drawings. a ".f.
This invention relates to improvementsin electric generators, more particularly to induction alternators especially adapted for use in connection with internal combustion engines. I have sought'to reduce the costs of production and to increase the efficiency oi the class of devices t o -wh ichf my .invention "relates. i For the purpose of disclosing my invention and its scope of application, I have selected the accompanying drawings" in \\'hich:- i V Figure 1 is a transverse cross-sectional view of an electric generatorembodying my invention. in a substantially full size scale of a machine which I have had in success.
t'nl operation for a long period of time.
Figure 2 is a transverse cross-sectional view of an electric generaton embodying a modification of the application of my invention, and shows the operating spring placed inside the generator. i I
Figure 3 is an end elevation of"Figure"1 with the face member of theop'erating lever removed. I I I Figure 4 is an end elevation of Figure 1 with a starting lever added and also shows an operating part of the engine on which'it is to be installed. Figure 5 is a view taken along line of Figure 2. i
Like figures and references denote the same arts .wherever they are shown.
In 81s drawings 46 lindijcates the rotor androtonshaft construpted a unit; 2 is a'baseaii'd p'ole piece of magnetie material which Ihave slipwnas a driit'arygoast ing; it'ean'be constructed of stampings svhere desirable.
The double actipg torsion spring-12 bodies "a unique feature of'my generator. It is shown enclosed in Figure 2 and exposedin Figure l 'and disposed on bearing 13 made ofeither magnetic ornon-ma netic material. A'lng lai is n ade a parto said bearing and"servesftoieiigage the ends 14.
i4} of spring jlt; A :liig"15?"ai rextension of operating oscillating lever'w is so correlated with the lug l i' 'that will freely-swing past same, It will. be noted that :thIspring ends 14, 14", also enga"e'l ug'15.' Th e torsion type of spring "can e'so formed that as it is put in place as shown inthe drawings, it will be strained so as to'be under pressure i. e. it will exert pressurelon the lug fixed to the generator frame and without exerting pressure on the trip finger lug until the latter is moved from rest. As it'moves from rest, it'engagesthe spring already under any desired tension. When desirable, the sprin may' be so formed as to be capable of "installing withoutbeing'placed under this initial tension, and just so its ends will register with ,either of the lugs, which may .be. of the same or varying widths, according to re'sults desired. While I have shown the torsion sprin e11 circling the shaft or a bearing and shai t, its form anddispositionare susceptible of many variations that will suggest themselvesto one skilled in the art. This is also true of the lugs; they may be dispensed with and other means provided for engaging"the spring ends; 'A"suitable device which is a part of the internal combustion engine on which'my generator is to be' placed" and which'is shown inFigure t engages with the faceljfi 'of lever 15 and moves'it in a clock- Wise direction as viewed in'Figure 4.
When lever, rotor and timer cam are released, the stressed spring 12 rapidly returns these members to rest. I It will be noted that this spring impels and then arrests the rotor andthe parts affixed to it.
Many widelyvarying embodiments of my invention-and various applications thereof, such as will suggest themselves to those skilled in theja'rt to which my invention relates, may be used and made without departing fromthe'spirit'and scope of my invention. My disclosures and the foregoing descriptions are purely illustrative and are not intended to be in any sense limiting.
