To all whom t may concern: y v
Be it ,known that'I, WILLIAM M. STEELE, a citizen of the United States', residing at Worcester", in the cuntyof Worcester and Commonwealth of'Mas'sj'achusetts, have invented a new and useful Improvement Vin Electric Timers for EXplo'sive-Engmes, of.
'tric current and al series of separate spark plugs connected with plosive engine. y
The object of my invention is to simplify reduce the expense, and crease the eiiiciency and durability of the device, and I accomplish these results by the construction and. arrangement of, parts as hereinaftendescribed and set forth'in the annexed claims. v y l Referring to the accompanying drawings,
the cylinders of an ex- 'Figurel is a diagrammatic viewv of a boX- p contamlng spark coils, an
electricl timer embodying my 'present invention, and illustratingthe system of wiring in connection :with the spark plugs of an automobile engine. Fig.2 is a plan view oa timer, shown f ull size theco'ver removed to disclose the interior mechanism. Fig. 3 is a vertical central sectional vew on the plane of the broken line 3-3, Fig. 2. Fig.- 4 is a detached central sectional AView vof the rotating spindle and contact wheel.- Fig. 5 represents a. sheet metal blank from which the bracket supporting cont-act wheel is formed. Fig. 6 yis a detached perspective view of the bracket for supporting the contacttimer. Figs. 7 and 8 represent detached-pieces forming one of the contact terminals. Fig. 9 is a de. tached view of one of the contact terminals. Fig. 10 is a sectional view of the insulating ring and representing one of the contact terminals held therein. Y Y Similar reference characters refer to similar parts in the different figures.
M v improved timer comprises a ring 1 of insulating material mounted uponan annular disk 2, suitably supported and pr'ovided on one side with a radial arm 3 bywhich a rotative adjustment ot the disk is e'ect'ed. Upon the ring 1 is placed a cover 4 held in place by bolts' 5, each provided embodylng my invention and havingwitlra .thumb nut,'.o'neio'f which is shownat 6, Figf3. `'lliegboltsf5` are "attached to the annular disk; 7i and pass-up through the insulating grillig` v1, fwliereoy' the-disk,l .and cover `are '.gecurely :clampedf together means of the;-nutsc..Theldisk2 is provided with a hollow."` hub ithe'.upperfend-fofff which is tightly i drlven aff'iringj a ball track for a-ro`w 7 having withln the rings 8 and 11'- isl a 'ls'pindlelll 8 havinga.. beveled surfacejfwhichfformsone side of.
of rictionballs .10;` second ring 11 is placed loosely i1'1"the`=h i-1b' i a" similar beveled surfacel12-bearing' against the .-friction`balls-10. 1 Journaled provided with a semicircular ball -r-sfic`ef14f An elastic Washer 15 is' the ring 11 and beneath the elastic/.wasl'le' 15 is a flat washer 16 which is held in place bv an elastic split ring 17 .which is sprung into a semicircular'recess in the interior wall of the hub 7. Beneath thewasher 16 is an annular piece of felt 18 filling the end ofthe hollow hub and preventing the dust. The spindle 13 is provided with a shoulder 19 which bearsupon the upper surface of the ring 8, and the spindle-is'hveld in place-'by means of a collar 20 and set admission of placedl against` screw 21. The hollow spindle 13 is vprovided with. a series of longitudinal slits 22 which permit the hollow spindle to be compressed by the set screw 21 and clamped 'upon the Y end of a. revolving shaft drivenbythe mojf tive power of the automobile.
l Mounted upon' the upper end .of dle 13 is a bracket 23 which isfriedf'frpm a blank 24 of sheet metal, the fdrm'ofw-lii'ch is represented in'F-ig. 5, consisting-of a -circular disk having on tongue 25. The disk is cut on the dash and 'dot lines 26 and 27, and the tongue 25 thus Vend bearing against separated from the disk is bent on the/dotted line 28 at right angles 'to the diska'nd -is again bent at right angles at 29. vThe disk 24 is provided with holes 30 by which it vis riveted upon the end sides 31 formedby the removal of. the tongue 25 form'guide Ways for a sliding U-shaped frame 32 in which spindle33 which forms a bearing fora rotatable annular roller 34. The upright portion of the bracket 23 is provided with lan opening 35 36 inclosingv a spiral spring 37, having onethe bottom of the spring case and the opposite end bearing against the Ushap'ed frame 32, so that the tension thespipone side a projectingis .held a. cylindrical of the spindle 13. The
to receive a .tubular spring case the periphery of the rot .copper bloc-k 46. "heu the the outer side ofthe 'block and.
` sponding to .the
` held in the mortises of said ring, each of 'metal holder having of?l the spring 3T will be applied to push atable roller 34 of thel insulatiirg` able intervalsy in the inortises, a series of contactterminals held in .said lnortises, each consisting of a flanged sheet metal holder, with 'its against, the, inner wall of said ring, means vt'or pressing' said fiange against the ring, a contact. hloelc held in said holder, a screw held in said holder, and a nut carried by said screw.
3. In a timer for of. insulating material having a series of mertises at stated intervals., a series of contact, terminals inserted through said moragainst; the inner wall ring 1. Inserted at snit insulating ring 1 are a series oi eentact' terminals 3S. The ring in the present in` Stance contains four equallv spaced. and each provided with binding posts 2li) tor'lhe attachment of the wires .ltl, Fig. l, connect.- ing said binding posts with the coilsl ofE a. coil box 4l suitably connected by a .virell with a battery, and' also In wires 43 with a asheet.. metal holder lf. Fig. T, between the. opposing sides of which is inserted av bleek of` eopper 4G, Fig. S. 'lhe. contact. terminals are inserted through mortises formed in the insulating ring 1 and the flanges 47, 47, of. the terminals bear againstl the inner wall of the .insulating ring. A screw 48 is -held in the holder to receive 'a nut 49 constituting the binding post of theterminal. rI`he sheet. met-al holder 45 is eut away atl each end, as at 50, to expose the. outer surface of the terminals have been inserted in the insulating ring l an tric conducting material. a flange hearing against the inner surface -of said ring, with the outer side 4of said block arranged to be expanded in order to draw said flange firmly surface.
4. In a timer ringof insulating material., a Series 0f contact terminals held at stated' distances in said ring, each of ing a sheet metal clamp inclosing a block of electric eonductinglmaterial, and provided vwith a flange bearing against the inner surface of said ring, a binding post held outside said-ring, and means forbringing said terminals successively into an electric circuit.v
5. In a timer for explosive engines, a ,rotating spindle, a series of spaced Contact terminals concentric with said disk attached to the upper end of dle having an integral tongue cut; disk and bent upwardly andw witlrsaid disk to.'form a guideway, a U- shaped frame slidable in 'said guideway, a
and provided with arbor is placed within the ring to serve as an anvil and each of the copper blocks are Spread by a chisel pointed instrument, as shown at 51, 51, Fig. 10, in order to expand draw the f'langes 47 firmly against the inner wall of the insulating ring. A rotary mot-ion having been imparted to the spindle 13 correspeed of the engine, the rotatable roller 3l will be carried around in contact with the inner wall of the insulating ring completing the electric circuit each one of the contact termisaid spinfrom the time it passes over Contact roll carried by said frame, and means nals 38. forrotat'iiig said spindle.
