Be it known that I, `JOSEPH Lizo'rrn, ofA
5 and useful Improvements in Igniting Mech i a'nisxn forEXplosive-Engines, of which the following, taken in connection with the accom- Y' panying drawings, is a specification.
My invention relates to igniting mechanro isms for explosive-engines and is a division of another application of 'mine for a patent fora gas-engine, filed June 28, 1897, Serial No. 642,569; and it 'consists' incertain novel features of construction, arrangement, and coinbination of parts, which will be readily understood by reference to the description of the accompanying. drawings and to the claim hereto appended and in which-my invention is clearly pointed out.
Figure lof the drawings is a sectional front elevation, broken away,of so much of an explosive-engine as is necessary to illustrate my invention. Fig. 2 is a sectional elevation, the cutting-plane being on line @c on Fig. l and Fig. 3 is a sectional elevation of one of the upper electrodes and its supporting devices, the cutting-plane being on line y y on Fig. 2. Figs. 4 and-5 are respectively an elevation and a 3o sectional elevation of one of the lower or oscillating electrodes. Fig. 6 is an elevation of the crank-shaft, cranks, and levers for operating the oscillating electrode and the eX- haust-valves of the'engine; and Fig. '7 is a sectional plan of the saine, the cutting-plane being on line 'u o on Fig. y6.
In the drawings, Aand A' are the two cylinders, mounted upon .the table or plate B, which in turn is supported upon suitable columns set in a bed-plate substantially as in my prior application, though said bed-plate and columns are not shown in the drawings of this application, and A2 and A3 are the cylinder-heads, having formed therein the eX- 4 5 plosion-chamber b, substantially as in my said prior application before cited. l
The arrangement of the'eXplosion-chamber relative to and its connection with the cylinder of the engine, the means for mixing a suitable quantity of air with the gas and then admitting said airand gasv to thev explosivechamber, and exhausting the products of the explosion from the cylinder maybe such as are shown and described in my before-cited application orof any other well-known construction, my present-application being confined to the ignitin g mechanism forproducin g the explosions. v
The upper wall of the explosion-chamber b has a threadedopening therein in which is 6o screwed thetiibular and internally-threaded hub N, in which is adj ustably screwed the sleeve j, provided with the check-nut j and having iittedthereto, but insulated therefromV by the insulating-bushin g 7c and iianges 65 Ze', the stem Z, provided at its lower end with the head Z and at its upper end with binding-nut Z2, by which it is iirmly secured in said sleeve-j, as shown in Fig. '3. A wire 2 is irmly clamped in contact with said stemZ 7o by the thumb-screw Z3, and the opposite end thereofV is connected to one pole of afsuitable battery or other source of electric energy, (not shown,) the opposite pole of which is connected to any fixed metallic portion of the machine.
The head Z of the stein Z has iirmly secured in a socket therein the closely-wound spiral spring m, which depends therefrom and has formed at its lower end the loop m', which 8o serves as one of the electrodes or contactpoints of the circuit-closing devices, the other contact-point being the electrode O, set in a diametrical socket in the oscillating shaft O', mounted in the side Wall of the explosionchamber Z9, as shown in Fig. 1.
The contact end of the electrode O is made .up of the metal portion fn, formedintegral with the shank, the separate metal piece n', and the insulating material n2, inserted between 9o the metal `portions n and n and extending between the lower end ofl the piece n and the shank O and upward outside of said piece n', the parts being secured together by the washer n3 and screw n4, as shown in Fig. 5.
When the upper end of theclectrode O is oscillated toward the front of the explosionchamber, the portion 'n comes` in contact with the loop m of the spring-electrode 'm to close the circuit, and when said contact is broken roo by the continued movement of the electrode O in the same direction a spark is produced and the gas is ignited. lWhen the motion of said electrode O is reversed and its upper end is moved toward the rear, the metalv piece n comes in Contact with the loep m', but no circuit is closed for the reason that the piece a is completely insulated, and as a cense- (luence no spark is produced when the contact between said piece n/ and the loop m is broken.
The hole through the metal piece n for the passage of the screw n" is made considerably larger than the shank of said screw, so as to insulate it therefrom, as shown in Fig. 5.
The shaft O' has lirmly secured upon its outer end the radius-arm l), to the movable end of which is pivoted one end of the connecting-rod l, the opposite end of which is pivoted to the frontend ol thc lever l, which is fulcrumed upon a stud j?, set in the Side ol;I the segmental. casing Q, which is supported upon the plate l above thc central pair of columns (not shown) and between the two cylinders A and A', as shown.
The easing Q incloses the sprocket-wheel Q, mounted upon the shaft (l, Iitted to bearings carried by the lower ends of the two arms of the forked yoke R and projecting' through slots in the sides of said casing, said shaft having secured upon each end thereof outside of said easing` a crank-disk g, in which is set a crank-pin rf, upon which is loosely litted a block o, which in turn is litted to and movable cndwise in a longitudinal slot Q, eut through. the rear arm ot the lever l, as shown in Figs. li and 7.
'lhe sprocket-wheel Q' is related by the chain ',l, to which. motion is' imparted by a sprocket-wheel on the main crank-shaft having a diameter equal to just one-half the diameter of the sprocket-wheel Q', as shown and described in my before-cited application, whereby the shaft q makes one revolution to two revolutions of the main crankshaft. (Not shown.)
The shaft q may be adjusted vertically by i the setsscrew t, threaded in the upper end of the yoke R and bearing upon the top of the casing Q for the purpose ol adjusting thc distance between the sprocket wheels to the length of the chain T.
The operation of my invention will be readily understood from the foregoing without l'urther explanation here.
rlhe parts herein claimed are shown and described, but not claimed, in my before-cited application, of which this application is a dvision.
Vhat I claim as new, and desire to secure by Letters Patent of the United States, isM
The oscillating electrode O, the contact end of which is composed ol.' the portion n integral with the main body or shank, the metal plate n',the insulating materialnthe metal washer n and the screw n insulated from the plate n', in combination with a normally stationary but yieldable electrode arranged to be intermittently contacted by said electrode 0; and means for imparting an oscillating motion to said electrode O.
ln testimony whereof l have signed my name to this specification, in the presence of two subscribing witnesses, on this l 5th day ol' November, A. l). i807.
