AUG-U31 EBILIP SEISS, OF OMAHA, NEBRASKA, ANLDv GEORGE WILLIAM RDHRIG, OF

COUNCIL BLUFFS, IOVJA.

;GOBBINED. SHA K-BLUE, RI ER A D INDICA R- State oi Nebraska, and GEORGE ROH IG,

a citizen, of; the United States, and resident of Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented a new and Improved, Combined Spark- Plug, Primer, and Indicator, of which the fo lowing is a full. clear, and exact descriplion.

Qur invention relates tov spark plugs for internal combustion engines, and it is a dethe nv nt an o p d a pa plug, and appurtenances which, iii-addition to tii e usual functions, oi the plug in pro.

ducting the ignitionsparhwill serve as a pringer, and, a so serve to indicate. whether a particular cylinder is doing its work or doing; it properly. v

litis a design or our invention to provide device. oi the indicated character,

efficient in operation, and characterised by simplicity ofadjustinent and control.

1 (v-distinguishing; featuresof; the invention, and; thefimportant structural elements,

characterizing the preferred embodimentwhich. is illustrated as an example, will be moxie particularly explained in the specific description llfilelpg tfi l to, be given.

Relierence is to,be.had to the accompanyin}; drawings forming a part of. this specification, in which Slmllar-eharacters of ref ven end c te, or esponding Part n the views,

binatipn spark; plug, primer and indicator embodying our invention, and showing the same a'pplied; Fig.2 is a fragmentary vertical section showing; an adjustment of the -valvev means whereby the device can be emplo ed an indicator to test whethenthe cylinder is working properly; Fig. 3 1s a similar view-showing the adjustment for the device toconstitute a primer; and. Fi t a plan VlOW of the parts shown in l 2 and 3. v

In constructing our device in accordance with the illustrated example, the body of the plug is made of a form to be received in, the c linden and provided wit-ha core 11:, insu ted from the. body 10 by the;sleeve 12, the said bodyand core being pro'videdj at e ne nd, with. e min 1 Specification of.- Letters Iatent. s n ano nasmuch as, ism.

Near the lower end of; the core 11 a lateral shoulder 1.6 is fiormecl to receive a suitable packing 17. The upper end of the core is threaded, as at 11, and receives outside of the sleeve 12, a nut 18, the tighteningof which draws the inner shouldered end-of the core against the packing 17 which is seated, on a; shoulder 12 formed on the interior of thesleeve 12.

Fitted in the valve casing 21 is a'valve 24, illustrated as a cook having a transverse passage-25, which,' by the turning of the valve, may be brou ht into reg: ister with the bore'22 of the va ve casing, or disposed transversely thereon to close said bore and thus close the tubular core Ofitht:

The passage 25 in the valve2l is contracted at its inner end to provide a valve seat 26 on which an auxiliary valve 2,7 is adapted to seat, said-auxiliary valve being capablevof play in the passage 25 toward and from the seat 26.

In connection with the valve 24 and its passage 25, by passes are produced or the purpose of permitting a priming charge to pass from the cup23 to the tubular'sparlr plug, and for providing in another adjustwant of the valve Zl, ;1for o'hservi g ft-he workings of thegcylinder, permitting a portion of the products of'cornbustion 0t an pl arge to passar ndhe n a y. alv an mugh; he ma n. al w r ly hrou h, e-Pr m 0P to idileate vvhe-ther the cylinder is working'or working properly.

- an open position with the auxiliary valve;

i 'der, so that portion of the products of "/comhustion Wlll pass around the valve through the by-passes 28, 29,- and out through the priming cup, to whether the particular cylinder to which the plug is afiixed is properly performing its functions. A third by-pass passage 30 is formed in the bore 22 of the valve casing below the valve 24, and when the valve 24 is turned to the position shown in Fig. 3, the by-passes 28, 80, will be in register with each other, and there will bea clear passage from the priming cup through the mainvalve passage 25, and tht bypasses 28, 30, to the spark plug, for the delivery of a priming charge around the auxiliary valve 27.

The valve24 has a lever handle 31 for turning the valve, and in practice, said handle will bear on one side the word Indicator and on the oppositeside the word Primer, as indicated in Fig. 4, and when said handle is turned to the vertical position the spark plug will be closed and free to perform its usual functions in the ordinary manner. If the handle be turned upwardly in one direction, say to the left, as in Figs. 2 and 4, the valve means 24, 26, will be so disposed as to allow the device to function as an in dicator; .while if the handle 31 be turned to the right, as in the dotted lines position in Fig; 4, and as shown in Fig. 3, the device may function as a primer. The valve 24 has any approved means for holding it tightly in place, being provided, for instance, with a stem 32 at the end opposite the handle 31, which stem receives washers 33, 34, between which is a helical spring 35, a cotter pin 36 being employed to retain the washers and spring in place,

Having thus described our invention, we claim as new, and desire to secure by Letters Patent:.
