IGNITION DEVICE FOR INTERNAL-COMBUSTION' ENGINES.
Application filed November 8,' 1921, Seria1-No.v513,766. Renewed August 28, 1924.
To all whom t may conce/m: A
Be it known that l, HARRY ELDRED TAY- Lon, a citizen of the United States, residing at Paris, in the Republic of France, have invented new and useful Improvements in Ignition Devices for Internal-Combustion Engines, of which the following is a speci\ fication. Y
My invention relates to improvements in ignitiondevices with induction coil for internal combustion engines, whereof the principal advantage consists in producing a spark within each, cylinder of the engine not only at the end of the compression stroke as in known devices but also during the exhaust stroke, thereby obtaining the complete combustion' of the gas within the cylinders.
Another advantage resides in the fact that great facility. Furthermore, the construesired position. The lframe 50 has formed ,The other arm of the said lever 1s normally tion of the apparatus is of a very simple character and provides for the perfect insulation of the electric conductors.
The following description together with the accompanying drawings which are given by way of example ets forth an embodiment of 'my invention, wherein:
Fig. 1 is a longitudinal section of the device. .f p
Fig. 2 is a partial longitudinal section' approximately on the line A-A, Figi 1. Fig. 3 is a front view of a detail ofthe actuating device of the camy of the makeand break device. v
Fig. 4 is a diagrammatic cross-section of the high tension distributor approximately on the v'line B-B, Fig., 2.
The apparatus herein represented comprises a mainvframe of cast aluminium. having formed in the rear'sidethereof a recess 51'adapted to' receive a projection of one of the engine parts whereby the frame 50 shall be maintained exactly in the de" therein an inclined aperture 52 *whichl receives'a bolt 53 serving to secure the said frame to the cover ofN timingy gears of the engine, for instance a Ford engine. The
' said bolt may also serve in the 'case of this latter engine to regulate the tension of the belt o f the air fan.
Thellower part of the frame 50 is proi vided with an aperture having disposed therein the cam shat 54 of the engine whereupon is rotatably mounted the pinion- 55. The shaft 54 has keyed thereon a sleeve 56 having pivoted thereto two arms 57 constituting a'centrifugal governor. The said arms are connected by. the links 58 to a cam 59 4centered upon the shaft 54 and provided with eight bosses cooperating with a fibre pm 61 secured to the semicircularlever 62 of theI interrupter device. The said lever is pivoted to a screw 63 for grounding the same, and is ,broughtl back by a'spring 64. The lever 62 is provided' withf a tungsten point 66 cooperating with' a stationary insulated contact stud 67. The frame 50 has formed at-the top part a hollow cylindrical portionrconstituti'ng a casing 50' for containing the spark coil 68.l v
The contact stud `67 is connected by a wire 69 to a contactstudZO disposed in the.
bottom of .the casing 50', The lwire 69 is contained within a porcelain tube 71 which is. surrounded ,by the metal of the frame 50, thereby' affording a perfect insulation and obviating all visible wires..
The spark coilr68 comprises the soft iron core 73 and the primary` winding 74 iconnected with a condenser 'and with a spring contact plug, 7 6 cooperating with the contact stud whenv the said spark coil is disposed within, the casin y 50. The other end of theprimary win inl is connected with the spring contact plug 7 cooperating with a stud 78 disposed upon a casing 79 of insulating material. The latter is secured to the cover 80 of the casing 50 by a nut 7 9. The stud7 8 is connected with-a wire 81 havin a suitable resistance and .wound in a suitable number of turns about a metal tube or rod 82 which is secured at 8,3 to the receptacle 79. The end of the wire 81 is connected with a small automatic switch constituted by a bell-cranklever 84, or the like, whose' vertical arm is adapted to be driven back by the .tube 82 when this latter? is caused to `expand by the action of the heat produced. by the current \in the Wire 81.
. stud 70 with a wire 96 which is also contained in a porcelain tube 97 surrounded by the aluminium frame 50. The-wire 96 ends in ag'contact stud 98 cooperating with a stud 99 provided upon the rotary cont-act disk 100; the latter has disposed thereon the drivi ingpinion 101 'and' is mounted -on a ball bearmg 102. K
In the example herein represented which Vis applicable to a four-cylinder engine, the rotary contact device comprises suitable conductors connecting the stud 99 with a tungsten point 103 disposed on the surface of the said disk and with a second tungsten pointv 104 disposed on the periphery of the disk and diametrically opposite the former. The stud 99 is also connected'with a like metal y l* point 105 constituting a lightning arrester together `withna,y stud 106 secured to and grounded upon the machine (pinion 101). '.,lhe metal point 103 cooperates with four tungsten inserts 1, 2, 3, 4 disposed on the internal wall of the high tension distributor 107, of the said rotary contact device. rlhe metall point 104 cooperates with four like inserts 1, 2, 3, 4 `disposed on the internal periphery of the said distributor plate. The eight studs are connected in pairs with four contact members 108 mounted in said distributor plate as shown in Fig. 4 andrespee- The pinion 101 of the rotary contact de' vice is actuated by the gear wheel through the medium of the pinion X110 which is nounted on ball bearings within the frame 5 The cover 80 of the casing 50 is ma-intained by the fastening device I111 which' is for instance of the combination lock-type. The owner of the vehicle is thus enabled to remove the spark coil with facility in order to prevent theft of the vehicle. The said apparatus 'operates in the following manner:
The primary current having been brought to the binding posts 87, 8`8 and the cam shaft being actuated, should one of bosses of the cam 59 encounter the pin 6 1, the movable contact piece 66 will become separated from stationary contact piece 67. The break of the primary circuit thus ensuing will give rise to a secondary current which is sent by the rotary device 101 for instance to the metal point :,104 cooperating with Vthe metal stud 1. The apparatus -is so adjusted that the spark thus produced takes place in the first cylinder at the end of the compression stroke, for instance45% of the crank shaft before dead center. It will be observed that the points 103, 104 do not enter in friction contact with the metal inserts of the -distributer, but the current passes in the form of a jump spark between each point and the corresponding inserts. lhave the eli'ect of increasing the intensity of the spark at the spark plugs and will also reduce the wear and obviate the bad contacts resulting from the use of carbon brushes.,
At the end of a quarter of a revolution, or approximately, of the cam shaft 54, another break of the primary current will be produced at this moment the metal point 103 comes opposite the inserts 3fand the current is caused to lpass into the spark plug in the third 'cylinder which is now in the exhaust stroke. Shortly after a fresh break will take place and the oint 104 will cooperatewith the insert 2, t ereby sending the current to the spark plug of the second cylinder which is now acting at the end of the compression stroke and so on'. The explosions have for instance the following sequence: 1, 3, 2, 1, 4c, 2e, se, 4e.
llnasmuch as the spark is thus produced in each cylinder during the exhaust stroke, the gas which is not burnt and, which remains in the cylinder may be thus consumed as well as the oil which is projected by the piston during the exhaust stroke, at the same time obviating all explosions inthe muflier box and the damage ,resulting therefrom, and likewise the fouling of the spark plugs.
determined by the position of the-weights 57. As the speed increases the weights move outwards because of the centrifugal force,
It will beobserved that the two contact members 78 and 92 are so disposed that by turning the casing 79 and thereby reversing This will i The driving relation between the drivingY member 56 and the p1nions`55 and 101 is said contacts, the direction of the current may be reversed thereby reducing the wear of the tungsten points of the device and the electrodes of the spark plugs. In case the primary current is supplied by a battery, should the driver fail tor switch off the current when 'the' engine is not running, the said current; by passing( through the wire 81 and heating the tube 82', the Alatter will thereupon expand and will act upon the bell-crank lever 84 thus automatically cuttingo the current.
It is obvious that my said invention is not limited to the details `of construction as hereinbefore set forth, the same being given solely by way of example. A suitable plate may be supplied with the device when employed on an engine other than the Ford type, whereby the said device may be secured with facility to the engine base plate adapted for a magneto or the end plate of a dynamo.
Having now described my invention, what l claim as new and desire to secure by Letters Patent is: A
1. An ignition device for internal combustion engine embodying a single metal frame having formed therein a recess by means of which it is liable to be secured onV a corresponding protruding portion of the engine and a hollow part which forms a terrupter and the distr`ibuter on the other hand.
2. An ignition device for internal combustion engine embodying a single metal frame having formed therein a recess by means of which it is liable to be secured on a corresponding protruding portion of the engine anda hollow part which forms a casing, an induction coil removably mounted in said casing, an interrupter -for the primary current and a rotary distributer for the secondary current mounted on said frame, and electric connections between the induction coil on the one hand and the interrupterand the distributer on the other hand, said electric connections embodying electric conductors inserted in porcelain tubes which are embedded in the said metal frame. f
Intestimony whereof I have signed my name to this specification.
