Beit known that I, GERALD S. SUTLIEF, a citizen of the United States,' 'residing in Perry Creek township, in the county of Vigo and State ofIndiana, have inventeda new and useful Engine-Starter, of which the following is a specifica-tion, reference being had tothe accompanying drawings land to the letters and figures of reference marked thereon.

This invention relates to mechanism for starting explosion engines when at rest, more especially when compression occurs in the engine cylinders, the invention having reference particularly to a safety engine starter that is adapted to be operated by foot power.

The object of the invention is to provide will be adapted to be applied to automobile engines and so constructed as to be capable of' being operated by a person in the operators or drivers seat, a specific object being to -provide engine starting mechanism ofthe above mentioned character that will not be injured .in case the engine kicks back or back fires, and which will prevent the operator from being injured under similar circum.

'he invent-ion comprises ratchet mechanism of novel construction including an arm j performing the functions ofa'pawl and havhead being-retractedou't: of range with the.l projections in case'the wheel moves backward, the mechanism including also an op* eraf-ing leverand` connections betweenl the lever and the ratchet mechanism.

Referring'to the drawings, Figurel is\a such as. might be used in automobile con'` struction, a crank shaft mounted 'on the starting apparatus, the outlines of` an ex-y plosion engine being briefly shown by broken the engine' starter shown in normal rest starting apparat-us in the position occupied in case of back firing; Fig. 4, aA fragmentary arm; Fig. 6,a fragmentary section1- on the plane of the line A A 1n Fig. .4 but 'with the apparatus in loperativeposltion; Fig. 7, af

' ferred to.

perspective view of the' aforementioned arm minus the retractable head; and Fig. 8, a

fragmentary section Von thev plane of 'the line BB in Fig. 6.

'Similar reference characters throughout the drawings indicate corresponding eleconstruction herein re` ments' or featuresof In the drawings land 1 indicate the main journal-box mounted on the: bar 2, 4 the main shaft of the engine rotatably mounted at one end in the journal-box and` havin' cranks' and`5, an4 engine 6 being mounte or longitudinal barsof a suitable frame, 2 and 2 transverse bars lof the frame, 3 'ay on the frame for actuating the crank shaft. I

The forward end of the crank shaft has .a squared portion 7 to which ahand crank may be applied for rotating the shaft if desired to vdo'so directly by hand, as when repairing or adj listingA parts of the engine.

' The crank shaft l extends forward beyond the journal-box 3 toward thentransverse bar '2, and a boxl or .support 8'is mounted on the bar 2 and fiXedly support-s a hollow axial' shaft 9 which extends rearward to the .end

,of the crank shaft 4 and over the squared Vportion 7, the shaft 9 being in alinement 'with the crank shaft. A fly-wheel lO-is secured to the forward portion ofthe crank shaft :4 and extends rotatably `about the injections or pins 11, 11', 11'. c

An arm 12 providedA with an opening 13 ing provided with a suitable. number of prois pivotally mounted onI the hollow shaft 9 guide 15 eXten'dingabout one lside and thel opposite end thereof, the guide having a groove 16 therein so as to serve 'asia portion of a guide sheave, and during certain movevner 'end 4portion of the hollow shaft 9, the i forward side of the rim of the fly-wheel be# ments of the mechanismina measure pervforms the function of a driving-pulley. A head -17 is provided with a guidewayar-- ranged ,longtudinally therein which receives the .guide-bar 14 vand the head is movable on the guide bar so asto effect a lengthening or shortening ofthe arm. AThe head has a Hat front .face 19 ada ted to engage'the projections on; the fly-w eel and it has also: 'an

oblique-angled end 20 which enables the .pro-

,jections lif they'come, in contact'therewitllito push thahead inward when the ily-wheel fully ret-racted.- A lever 21 has `a bifurcated end portion 22 which straddles the arm 12 and is connected tothe arm by means of a l in the groove 16 holds the lever 21-against the stop 24 and forces the head 17 outward,

pivot 23, the arm being provided with a suitable stop projection 2 4 to limitthe movement of the lever inone direct-ion. v The bi furcated end of the levervis provided with Aa pivot pin 25 to which astifi' link 26 is con: nected, thelink being connected by means of a pivot 27 to the movable head 17. The lever 21 is provided also with a pivot pin 28 to which is connected a suitable cable 29 lwhich, during certain posit-ions of the arm,

extends into the groove 16, and the cable extends about a sheave 30 which is `suitably mounted on the frame ofthe automobile.-

The cable is connected to the lower portion 3l of an-operating foot lever which is suitably mounted on -the vehicle frame by means of a pivot 32, and it will be clear that .the arrangement may be such thatthe upper end portion 33 of the lev'erlmay ex-tend through a slot in the floor of the vehicle body to be pressed forward by the foot of the operator,

said upper portion being provided with a loop 34 into which the foot may be inserted for`drawing the upper portion of the lever backward. A coil' spring 35 is connected to vthe upper portion 33 of the lever, a cable 36l being connected to the spring and extending about a sheave 37 suitably mounted on the vehicle frame,.said cable being connected to "the pivot pin 25, so that the foot lever and the connecting cables control the movements and determine relative positions' of the dif,- ferent parts of the starting mechanism.

In order to guard against accidents in casethe engine kicks back in attempting to start it, a suitable plate spring 38'is supported in a suitable position, preferably on a bracket ,39.secured to the vehicle frame, and the spring supports a retracting bar 40 which has a fish tail shaped end 41 to receive the extremity of the head 17, when the latter s is projected and is being carried backward,

the bar 40 normally being in the path of the head and is permitted to swing as on a pivot to the extent of the elasticity of the spring, the bar being swung upward in contact with the supporting bracket.

In practical use the upper portion 33 of the operatin lever is drawn rearwadas in Fig. 1 Whio moves the arm 12 approximately to the position-shown in Fig. 1, the projection 11 on the fly-wheel bemg 'approximately in a position indicated when compression occurs, the head.17 being `be,` hind the projection..- On movement of the end portionV A33 forward, the cable 29 being so that on further movement of the operating lever the -head 17 engages the projection 11 and turns the yfwheel forward, theoperatinglever being pushed forcibly Vand briskly so that the iiy-wheel is forcibly turned through nearly one-half of the revolution and given some moment-um to further rotate it. If explosions` take place. as they should the engine continues to run under normal conditions, but in case of failure on the first attempt the operating lever is again manipulatedv so that the cable 36, lying in the groove 16, turns on the bifureated end to operative position as before, and then another e'ort may be' madeto start the engine. AWhen the engine is running the arm 12 hangs down approximately as .shown in Fig..2, the lever -21 being in horizontal position and holding the head 17 up out ofthe way of the pro'ections .on the iiy-wheel. When the head l passes downward in projected position it strikes thetop of the bar.

40 and readily pushes the bar out of the way, but when the head is c'arricd upward,

as illustrated in Fig. 3, with the head pro-v jected, the end of .the head will pass into the recessed end 41 of the retracting .bar and while pushing the bar upward would be.

retracted by the bar as the latter moves into aline drawn from the support of the bar` -through the axis of the crank shaft. Such.

` before bein carried-back to any appreciable extent. en the arm is moved backward from the position shown in Fig. 2 to the position shown in Fig. 1 the head 17 is held in retracted position by means of the cable 36 which is operating to move the arm upward but, since the spring 35 affords a yielding 'connectionjitfis clear that when,the cable 29 is under stress the lever 21, when the, arm 12 is approximately upright, is movedl so as to project the head 17 to operative position.
