' EnwABn r.:-nUss Ln Ann nuennn LA'voIn, or LOWELL, nnssncnusnr'rs f' -Be it lmo'wn that .W ,.EDWARD F; RussnLn 'a'nd EUGENE E. LAvIE, both citizensof' the- United States,- residing at Lowell, in the fi 'c'ounty of Middles'ex'and Stateo f M'as'sachusetts, have. invented certain new and use- Starting-Devices, of which the'followingis urv Invention relates'to automobiles and especially to the mechanism -for starting explos ve engines therein. .The ordinary methodof starting is to turn over the engine" by the used a c'rank which is arranged with a tooth or clutch whichenga es apin on-the. end of the main engine raft, By. this" method,if the crank is turned forward, theengine .is turned over in the-"forward direction, andif the ,crank is turned the'other 2o Way, 1t is released from the shaft. Such 'a'" crank is'usually'infrontof theradi'ator or; hood, b11 t 1n"s0nie styles of machines, it is' ;on the side of the automobile somewhat in a the rear ofithe drivers seat; With such a 25. cranking system, it is necessary forthe'oper t ator to dismount to crank the'engine, and then return to his'plaee on the drivers seat.

This is inconvenient and troublesome,

Moreover, it' takes considerable s trengthnto turn over the engine, and if the engine back .fires, thecra'nk will be.-reversed, frequently causlngmjury to the operator, sometimeseven breaklng'an arm. i

The purpose of our invention 18130 provide a device by which the engine can be started without the operator leaving. the drivers seat.

Among others it accomplishes the follovv-- ing special objects. The starting lever is so 40 arranged that a bacltand forthmovement is transformed into a continuous rotar movement which is transmitted through the medium of shafts and gearing and a clutch, to-t-he engine shaft; This clutch is preferably of the friction type and is somade that after the engine starts, the clutch is released and thereafter there is, noclicking.

Besides the starting lever and the clutch, t he other principal'feature of our invention 5 is a release mechanisin 'which is operative only in case the engine reverses from any cause such as back firing. In such case, the connections from the starting lever are re leased from the engine connections, and are summon ng-niacinE-srAn'rINs pEvIcE.

C-is our hand starting lever and I) is the release-mechanism V .E is the friction clutch. I I

F is art of the frame of-an automobile, G is the y wheel and H is the engine.

' Ha nd lever- C is-pivoted at 21Ia't the side of the automobile in any convenient position whereby the starting handle 22 will be within easyreach of the hand of the o'per atorfas shown in Fig. '14:." It should be out ofthe way of the change gear levers, brake levers and other'levers which arerusually 7 near the drivers' s eat.-- This starting lever C is' provided with two 'interiorly toothedcon- '10'5 centrically'curved racks 23 and 24:,th'e teeth of which pointin opposite directions; Be-"- tween these. racks,:we locate an .e'lasticfcogi wheel K which is carried by cog shaft 30 at the end of which is a bevel gear 31 which meshes with bevel gear 32 on driving shaft 33 which is supported by suitable bearings 20 attached to the frame of the automobile.

This elastic cog wheel K is rovided with movable teeth 35 each of which is pivoted I mally keeps each tooth 35 pressed outward.

Consequently the teeth 35 will engage the teeth on say rack 23 when that rack is moving against said cog teeth. When that rack 23 moves in the other direction, however, its

teeth will pass over the cog teeth in the same manner as the teeth of rack 24 are shown at the bottom of Fig. 4. Thuswhen racks '23 and 24 are moving 'in the direction of the arrows thereon in Fig. 4, the teth of, 23 will H engage teeth 35 and cog K will be turned in the direction of the arrow thereon. On the other l1a11 d, when the racks are moving in the direction of the arrow in Fig. 3, the teeth of rack 24:Wi11 engage the teeth of cog K' and will continue to move it in the .same .direction as the arrow shown on cog. K. Thereby a. backward and forward movement given to starting lever C by means of handle 22, will continuously rotate cog wheel K. This rotarymovement is transmitted on the construction shown in Fig. I, through shaft 30, bevel gears 31 and 32, driving shaft 33, releasing mechanism D, driven shaft which is supported in suitable bearings, bevel gears 51 and 52, shaft 53, bevel gear 54: an shaft 56 of the engine H.

The clutch E may be of any usual type but is preferably a friction clutch of such type that while the engine is in motion, there will be no clicking. We prefer the type shown in- Fig. 8 wherein the sector like clutch arms 60 are pivoted on the hub 61 firmly carried by mam shaft 56.. The outer faces of these arms fit the interior face 63 of clutch drum 64 and they are pivoted to.. hub 61 at'points 69 whicharenearly in linebetween the frontedge of the arm and the center of shaft 56. Suitable springs 62' press them forward and hold them normally in engagement with theinner surface 63 of thedrum64.

At the baclg near the fly wheel G, we place a cover 66 for drum 64: which fits main shaft 56 with a smooth bearing fit, and is screwed or otherwise fastened to clutch drum 64. The outer end 65 or head of clutch drum 6% is pr:- t'erably formed integral therewith and is cut to form a bevel gear 55v to mesh .with gfiar 54. As'the head 65 also snugly fits s aft 56, the clutch drum 64 is thereby supbevel'gear 55" of clutch E to main ported by it and by cover 66. We prefer to place inside of this clutch drum Vaseline or perfectly noiseless. It is apparent that when moving in the direction of-the arrow in- Fig. 8 the biting surface 63 will seize hold frictionally of the adjoining surface of the arms 60 and will tend to swing the arms pivotally in the direction which will tend to force the back of the 'arm outward thus bringing the parts together still more closely.

The result is a powerful, noiseless clutch. Now when'the engine starts and begins to rotate main shaft 56 in the direction of the arrow, it will rapidly overtake the drum 64 and as it overtakes it, the friction between surface 63 and arms 60 will tend to swing the arms out of contact, thus releasing the clutch. It will thus be seen that the clutch E will start the engine, but when the engine is started and the starting mechanism is stepped, the arms 60 will release-themselves an thereafter while the engine is going,

will spin around freely and with little or no friction in the Vaseline or oil.

e, Glutch E s ould be placed on main shaft 56. inside of crank L. In the construction shown in Figs. 1 and 2, it,is between the' crank and fly wheel while in the construction shown in Figs. 14- and 15, it is behind the engine onthe .main shaft thereof and onthe o posite end thereof from crank L.--

There easing mechanism D isinterposed .between the starting gear 32 and the gear 51 which transmits motion to the clutch E.

heavy'oil 68 whereby it is self oiling and It comprises a solid or substantially-solid driving drum 7 0 carried by driving shaft 33 at the opposite end from gear 32. Driven shaft50 is centered the same as shaft 33 and carries a substantially solid driven drum 71 in close juxtaposition to drum 70.

On the face adjoining drum 70, drum 71 has 'a plurality of shallow pin receiving holes 72. Opposite these holes 72 in drum 70 is a singlepin hole 73 in which slidesa pin 74. Behind this pin is a spring 75 which normally tends to press the pin 74 forward into one of the holes 7 2 as shown in Figs. 5 and 6. Thereby the drums 70 and 71' will be normally locked together or if not locked, they will be looked as soon as 'sufiicient motion is transmitted to either drum to permit pin 74 to drop into any of the pin receiving holes. On the curved surface of drum 70, we p1vot'on a projecting hearing at 80, the substantially radial release arm 81. The short end of this release.

arm 81 enters a depression in pin 74 whereby,.b v moving arm 81', pin 74 may be withdrawn; At the end of arm 81, we-pivot at right angles thereto, a' letent 82, whichis normally pressed down rd by a spring 83 intothe teeth ofstationary ratchet 84 which is preferably fastened to the bearings20 of shaft 33.

It will be readily seen that normally pin .74 will rest in one'of the receiving holes '72 x 8. This motionwillbe transmitted through the various shafts-and gears to shaft 50 and --drun1s 71 and '(0. The moment these drums,

start backward in the directionopposite' to the arrow in Figs. 6 and 7, t-he'detent 82 will strike in one of the teeth of stationary ratchet'S-it, and will be forced back and up carrying arm 81- with it as shown by the dotted lines in Figs. 5 and 7 This action will withdraw pin 74 from the receiving hole in drum 71'and will also stop drum 70 and all intermediate mechanism between it and the starting lever instantly. Instead of the gear connection-between clutch E and shaft-50, we may use a chain 90 and sprockets 91; and 92 asshown in Fig. 9.

*Instead of the hand lever, we may use a foot rack M as shown in Figs. 10, 11,12 and 13. This comprises a foot rest 93, bearing collars 94, 94, and a spindle 95 on which are rack teeth 97. These rack teeth engage teeth 100 on a collarlOl revoluble on and dispense with still more shafts and gears, In this case. the shaft 30 carries elastic cog.

carried'by a hub 102 which is attached to; and carried by a shaft 103 which is con:

nected with the shaft 33 by'jany suitable connections. In hub 102 are toothed depressions 104 and in collar 101 is a squared hole 105 in which rests a squaredpin 106 with a beveled nose adapted to slide over depressions 104 in one direction and tocatch-t-hem when moving in the o posite direction. This pin is spriL'g-presse asshown in Fig.

11, the whole being a well known form of ratc het. This foot action does not continuously rotate the engine as does our hand starting device, but it can beused on certain .types of machines.
