`Application led July 26, 1918. Serial No. Zillli.
` To all whom t may concern.'
Be it known that we, GEORGE V. NoLTE, a
` l citizen of the United States, residing. at
Bellingham, ,in the county of Whatcom and State otWashington, and JAMES E. SMITH,
a citizen of the United States, residing at Beach, inthe county of Whatcom and State of `Washington, have invented a new and `useful Ignition-Plug, of which the following 1o` is a specification.
ur invention relates to improvements in j ignition plugs for use in interior combustion engines of `the seIni-Diesel type, which re- `qnire the services of a plug for a fewnnnutes at a time only to make a quick start; and the" objects of our invention are: first. to
provide an electrically-heated wire ignition l Vplug the, element of which,` when not required in theoperation of the engine, can be fing gases within can'readily he removed and replaced D I'normal engine operation; and third, which shielded from exposure to the rapidly movthe cylinder; second, which during is'of "a simple construction especially suited 'or small engines.
IWe lhave lbeen grantedfPatent Number 1249,465'011 Dec. 1i, 1917, for Objects Similar '.tothe'first two objects above stated and especially adapted to large engines. We attain these objects with the mechanism illustrated in the accompanying drawcylinder ca `Figure l is a plan view of our plug shown in operative position and having certain yparts broken away in order to show others hidden therefby, Fig.'2 is a front elevation of Fig l in section on a longitudinal medial plane, Fig 3 is a side elevation of Fig. l,
Fig. t isa side elevation of Fig. l having its entire upper lportionbroken away, and showing the fparts in closed ornonvoperative position Fig. 5 is a sectional view ofFig. 4 on a plage throug'hline L10-40, Fig. 6 is a sectional view of Fig. 2 on a plane line 9-9, and Fig. 7 is an elevation the electrode. ,g
Similar characters/refer to similar parte throughout.
More particularly' A is-a`portion of the in section. l is a hollow stud havin a c osed lower end protruding into the cy inders interior. ing transverse holes through the walls of the lower end of stud l within the cylinder. 1b
through 'has two registering holes View of l, 1el .are register-- to engage cylinder' cap A. l is the threaded upper and outer end of stud l. ld is a hexagonal ring boss on stud 1 to provide a wrench hold. le is a deep diametrioal score on the upper side and edges of boss ld. .2 is the metallic jacket of the electrode. 2a is an insulating bushing in a counterbore in the lower end of jacket 2. 2b is aninsulating bushing in a counterloore in the` upper end of the jacket 2 and extends above said jacket. 2 is a circular nut on 'top of bushing 2b. 2 is a ring 'boss on jacket 2 near its upper end. 3 is the central rod ofthe electrode and has head 3a on its lower'end bearing against the lower end of bushing 2a. The upper end of rod 3 is threaded and on it is screwed `nut 2 to hear on the upper end of bushing 2b. Also on this threaded end is screwed binding; nut 8b. l is the element, preferably made of refractory wire in the form of a helix. One end of said wire is connecte-d to rod head 3a and the other end is connected to the lower end of jacket 2; 5 is the electrode cage and consists of a tube having a closed lower end and neatly fitted for revolution in hollow stud l. The lower end of cage 5 nearly reaches Athe bottom 5a, 5 through its walls adapted to regi-ster with holes l, l8 when in the position 1n revolution illustrated in Figs. 1, 2 and 6 hut to the out of registry with said soles when turned through an angle of o to the position shown in Figs. 4 and 5. 5b is a ring hoes oncage 5 near its upper end adapted to hear on the upper end of stud l. 5 is a threaded flange on the-upper end of said cagewith which hand wheel 5e is engaged and more securely retained by pin 5d. 5f is a deep diametrical score across the top and sides oi' hand wheel 5e which registers with score le in boss ld when holes 5, 3a/register with holes l, laas shown in Figs. l, 2, and 6; Ibut is ati-ight angles with seid score when said holes are out of registry as shown in Figs. 4' and 5, 6 is a bushingnut screwed into a tapped hole in the up er side or' hand wheel 5e and hears on ring'- oss 2d. 7 is a gland nut engaged with-the threaded end lc of stud l adapted to compress packing 8 on ring boss 5*.
ln operation, threaded body 1b is engaged in a hole in cylinder A as shown only in Fig. 3, those parts of stud l of said stud and ica' below said.
threaded body protruding within said cyl- Y 2 makes a turning fit iii cage 5, and the joint between the two is sealed by'nut A6 clamping ring boss 2d on flange 5C. When said nut 6 is tightly` screwed down the electrode is turned with difficulty in the cage, but by easing said nut the electrode may be revolved freely. As noted, one end of element 4 is connected to rod 3, which is therefore insulated, while the other end of said element is connected to jacket Q which connects it to the engine frame or ground. One terminal, not shown, of a suitable source of electricity, not shown, is connected under binding nut 3", while the other terminal of said source of electricity is connected to the engine frame as usual. The electric circuit of said source of electricity is supplied with a switch as usual. In starting the engine this switchis closed and hand wheel 5e is turned to cause score 5t to register with score le when holes 5, 5 register with holes l, l, seeFigs. 1, 2, 3 and (3, 'and element l is exposed to the gases in the engine cylinder as described. But when the.
services of the hot element 4 are no longer required in the proper operation of the engine hand wheel 5e is turned to cause score 5f to be at right angles with score 1e which causes cage 5 to turn through an angle of 90 in stud 1 and holes 5, 5 are turned out of registry with holes 1, la, as shown in Figs. 4 and 5, and element 4 is shut olf from exposure to the said cylinder gases.
When it is desired to remove electrode 2 during the operation of the engine the battefry terminal undcrnut 3" is removed, hand Wheel 5e is turned to cause score 5f to be at right angles with score l", nut 6 is unsrewed, when said electrode can be removed a` pleasure. To replace said electrode the opposite order is followed. This mechanism is also suitable for use with a jumpspark element.
tion, what we claim as new and desire t0 secure by Letters Patent is l. In combination, the cylinder of an 1n ternal combustion engine, a hollow stud exigaged in the walls of said engine cylinder with its inner end protruding' Within the interior of said cylinder, and havingtwo registering holes through its walls within said cylinder; an electrode cage mounted for revolution in said hollow stud having two registering holes through the walls ofv its lower end, and adapted to be revolved to cause said holes to be in registry with said holes in said stud and also adapted to be turned to cause said holes to be out of registry with said holes in said stud; and an electrode mounted in said cage having an element of refractory metal connected to its lower end adapted to hang between the holes in the lower end of said cage..
2. In combination, the cylinder of'an internal combustion engine; a hollow stud engaged in the walls of said cylinder with its lower end closed and protruding'into the interior of said cylinder and having two registering holes through its walls Withf in said cylinder, and also having a stuflingbox gland on its outer end without said cylinder; an electrode cage mounted for revolution in said hollow stud having two registering holes through its lower end which are adapted to move into and out of registry with said holesin said stud when said cage is revolved, and also having a ring boss adapted to bear onthe upper end'of said stud beneath the packing of said stuifing-box gland; an electrode mounted in said cage comprising' a central metallicvrod, an outer metallic jacket insulated from said rod and having a ring boss near its upper end; a refractory wire one end of which is connected to the lower end of said rod and the other end of which is connected to the lower end of vsaid jacket adapted to hang between the holes in said cage; and a bush nut in the upper end of said electrode cage bearing on the ring boss on said electrode.
