I Specification of Letters Patent.
Patented Sept. 10, 1907.
Application filed October 8,1906. Serial lie/337,871.
and exact descripti n.
My invention relates to'a combined timer and dis-, tributer for explosion engines and is particularly applicable to use with explosion engines having a large number of cylinders, as, for example, six or more.
The principal object of the invention is to provide for the use of a battery or a dynamo as desired, both being permanently connected to the terminals of the timer and distributer and being selectively switched into action by merely completing their primary and secondary circuits at some distant point. The mechanism is designed to give both the battery and the dynamoa circuit closure or dwell suitable to their needs.
Additional objects oi the invention are to adequately insulate the secondary or high potential circuit notwithstanding the small diameters of the various parts; to have an upper casing made oi insulating material and yet firmly and removably fastened in place and finally to improve the various minor details oi the practical construction, particularly in certain locking means for preventing the loosening of the various terminal screws by the vibration.
With these and other objects in view the invention consists in the features of construction hereinafter set forth and claimed. y
In the drawings: Figure 1 is a sectional view of a combined timer and distributer embodying the principles of my invention; Fig. 2 is a transverse sectional view on theline I1-II of Fig. lyFig. 3 is a top orplan view;- Fig. 4 is a section on the l' e IVI-V of Fig. 1.
Explosion engines are eing increasingly made with a considerable number of cylinders in order to obtain great flexibility of action and less vibration, and in the use of such engines having six or more cylinders aneed arises for a combined timer and distributer capable of properly controlling the primary and secondary circuits of the ignition system. The control is obtained from a shaft rotating commensuiately with the engine and usually termed the half-time shaft because of the speed. relation most commonly employed. If the ignition of six cylinders is to be controlled by this shaft, it is apparent that only is available ior the entire action in each cylinder, and the mechanism used must be capable of attaining all the ncessaryfunctions by an angle of movement of 60 of the half time shaft. In carrying out my invention I aim to secure this result for both dynamo and battcry ignition.
Rcfcrringlo the drawings in which like partsare designated same reference sign, 1 indicates a 4 indicates a support having studs 5 extending through the slots 3, and 6 and 7 indicate springs andwashers surrounding said studs and bearing on the flange 2 to hold the casing linangularly adjustable but non-vibratable engagement on the support.
The half time shaft is shown at 8, and extends axially upward into the casing 1,- being provided with a cam 9 therein. The upper end of the shaft is enlarged or provided with a collar at 10, having a flat upper face 11. This face serves as a support for the distributer or flier hereinafter described.
The primary circuit closing and opening devices are particularly shown in Fig. 2. Two'vibrating levers or I vibrators of any sort 12 and 1.3 are pivoted respectively at 14 and 15 on the frame or casing 1. The vibrator 12 is employed exclusively for dynamo or magneto ignition whichl will generally refer to as dynamo ignition, and the vibrator 13 is employed exclusively'ior battery ignition; The construction and arrangement of these levers is adapted to their special functions.
The vibrator 12 is iorked or bifurcated, as shown at 12 in Fig. 1, so as to be capable of forking or straddling the cam 9. I A roller 16 is journaled between the two .members 12 of the fork, and this roller is quite small,
as shown in Fig. 2, for a reason which will be hereinaiterstated. By virtue of this arrangement of having the vibrator 12'forked and straddling the cam, it is possible to have the roller 16 as small as desired. Y
17 indicates a compression spring for normally impelling the vibrator 12 toward the cam 9, and 18 denotes an arm of the vibrator carrying contact 19. The fixed contact 20 is formed on the stem of a thumb wheel 21, threaded at 22, into a metallic base 23. This base is supported by the frame or casing 1, but is insulated therefrom by a plate'of insulating material 24., 25 denotes a spring impelled plunger engaging a fluted portion 26 of the thumb wheel stem so as to hold the latter in any position to which it is adjusted. It is evident that as the earn 9 rotates, 'the vibrator 12 will be impelled outward and intermittently break the contact between the points 19 and 20. The vibrator 13 is likewise spring impelled toward the cam by a spring 27, and carries a roller 28 to engage said cam.
29 denotes an arm of the vibrator 13 having a contact 30. The co'ntactBO moves toward and from a contact 31 on a spring blade 32. 33 indicates the metallic base on which said spring blade is supported, and 34 indicates a thumb wheel, having astern 35, threaded into the base 33 and fluted at 3'6 so as to be engaged by a spring pressed plunger 37. By turning the thumb wheel 34, the contact 31 is moved into a position to be engaged sooner or later by the contact 30. The base 33 or casing, an upper casing of insulating material, a :shell or ring having a peripheral depending web, permanently molded to said upper casing, and means for attaching 'said shell or ring to said frame or casing.
7. In an ignition system for explosion engines, a frame or casing, circuit interrupting means contained therein. an upper casing of insulating material, a flier or distributer contained therein, a shell or ring permanently molded to said upper casing and having a web depending about said frame or casing, and means for securing said shell or ring to said frame or casing.
8. In an ignition system for explosion engines, a block of insulating material having a recessedor chambered portion, a supporting blade projecting from said recessedor chambered portion, a spring blade also projecting from said recessed 0r chambered portion and adapted to complete different secondary circuits, said spring blade being limited in its axial movement by the supporting blade.
9. In an ignition system for explosion engines, a frame or casing having means for interrupting a primary circuit, an upper casing of insulating material supported by said frame or casing, a plurality of threaded'studs in said upper casing. and additional studs having reduced portions extending through said threaded studs to lock them against removal.
10. In an ignition system for explosion engines, a pluralitvot segments, metallic studs adjacent thereto, and springs intermediate said studs and segments to establish electricconnection therewith. i 11 In an ignition system for explosion engines, a casing of insulating material, segments within said casing. said casing having a plurality of radial holes opposite said segments, threaded studs in said holes, and additional studs with reduced portions passed through said threaded studs to hold them against removal. 7 p
12. In an ignition system for explosion engines, a casing of'insulating material, a plurality of studs therein, additional vertical studs passed through said first named studs to hold them against removal, and a cover plate on said vertical studs.
In witness whereof, I subscribe my signature, inthe presence of two witnesses. V
