Patented Uct. 299, 1918.

Continuation of application Serial No. 193,338, filed September 26, 1917, and division of application Serial No. 229,020, filed-April 17, 1918.

To all whom t may concern.'

Be it known that I, MANUEL Dn Anni- GUNAGA, a citizen of the Republic of Mexico, formerly. residing in Mrida, in the State of Yucatan and Republic of Mexico, but now residing'in the borough ot' Manhattan, in the city, county, and State of New York, have invented certain new and useful v*Improvements in Starting A -pparatus for Internal-Combustion Engines of which the following' is a specification.

My invention relates to `starting apparatus for internal combustion engines, and the starting appa 'atus that is the subject matter of the invention is particularly adapted to internal combustion engines of motor vehicles.

This application is a continuation of my co-pending application for starting apparatus for internal combustion engines, Serial No. 193,338, filed September Q6, 1917, and a division of my eo-pending application entitled Improvements in motor vehicles, tiled on even date herewith. In the last named application I have shown and described auxiliary steering apparatus for automobiles, with means for operating the same from the engine of the vehicle, means :l'or controlling the operation of the same,

and a starting device with suitable connections between the same and the means for operating the auxiliary steering wheels; and in said application I have claimed said auxiliary steering wheels with the apparatus for operating` and controlling the same, and also the combination of a starting device and said auxiliary steering wheels with means whereby they may be selectively controlled. In this application I aim to cover the starting device, connections between the same and the engine, and controlling mechanisni therefor.

One of the4 objects of the invention herein claimed is to provide a durable and efficient starting apparatus.

Another object of the invention is to provide a starting apparatus embodying a. spring as the motive power so as to render the device simple and inexpensive to keep in order.

Another object o1 the invention is to ino.

vide suitable means for controlling the operation of the same. i

Further objects and advantages of the invention will more fully appear from the This application led April 17, 1918` Serial No. 229,019.

following description taken in connection with the accompanying drawings illustrating the preferred embodiment of my invention.

lMy invention consists in the novel features of construction and combination of parts hereinafter more fully described and more particularly pointed out in the appended claims.

Fig. 10 shows details of part of the starter; and y Fig. 11 is a view taken on line 11--11 ol Fig. 7 showing manual means for storing up energy 'in the starter.

Referring to the drawings, a supporting trame 45 (sec Fig. 1) is bolted in any suitable inanner.. such as by bracket 4G, to the side trame -17 oi:l the chassis; and this supporting frame carries one end of a tubular supportingmember L18, the other end rof which in turn fits within an annular socket 49 extending from the endof the differential housing 50. rlhe opposite end of the differential casing has a similar socket L19 into which fits one end of a tubular member 48 the outer end of which is carried in a supporting socket 51 secured to the opposite side piece 47 of the chassis by a suitable bracket 46.

The differential shaft extends through differential housing 50 and a housing 52 (containing a starting device hereinafter more fully describedi supported by bracket 53 in any suitable manner from the side piece 41:7. The shaft within differential housing 50 is provided with two bevel gears 54, 54C mounted loosely on the shaft, and these gears mesh with the main differential or driving gear 55 mounted on the back of the differential housing and adapted to be driven by or to drive the engine shaft in any suitable manner.

Referring again to Fig. 2, the hub of the differential gear 54 constitutes a clutch member adapted to be engaged by a clutch member 62 carried by an annular frame keyed to the differential shaft 30 to slide back and forth thereon. This clutch member is provided with an annular groove 63 by means of which the clutch member is forced back and forth along the key 64 to engage and disengage the hub of gear 54. A, similar clutch device is keyed on the shaft 30 to engage and disengage the hub of gear 54 and these clutch members are operated by the control mechanism hereinafter referred to, for clutching one or the other of the gears 5a, 54 to the shaft 30, according to the desired direction of rotation of the shaft.

I lwill now describe the means for operating these clutch members by the control mechanism. The differential casing 50 is provided near each end' and just below the said clutch members with transverse guide rods 79, 79 (see Figs. 2 and Il). On the rods 7 9 there is slidingly mounted a cam member 80 having

sleeves

81, 82 for slidingly fitting the guide rods so that the cam can be slid back and forth thereon. The guide rods 79 at the opposite end of the casing are provided with a similar cam member 80 similarly mounted. The cam member 80 projects into the groove 63 of clutch member 62, and the cam member 80 has a similar projection extendingl into the groove 68 of clutch member 62. The

cam members

80, 80 are connected, respectively, by downward projections 88, 83 to an actuating link 811 having a short projection 85 extending through the floor of the housing and about the aXis of which the link is swung to move the cam members back and forth on the guide rods for operating the

clutch members

62, 62. The actuating link is operated by

pull wires

86, 86 running to the dash,

where they are secured to control lever 87 (see Figs. 5 and 5a). As shown, the

wires

86, 86 are secured to the lever 87 in any well known manner, such for example as having the wires connected respectively to the peripheral portions of disks 88, 88 which are rotatably mounted on a short stub shaft 89 carried by a lever 90 secured to hub 91 of the lever 87. The lever 87 is made out of some suitable spring metal so that it is normally held up into a notch 92 in the flange of the guard 92, but when it is desired to move the lever, it is forced toward the dash 98 so as to free it from the flange of the guard 92, whereupon it maybe moved in either direction. lhen brought back to the lneutral position and released, the lever will spring back into the notch 92.

rlhe numerals

94, 94 represent guides for the

wires

86, 86 which latter may be inclosed in suitable fieXible protecting sleeves, parts of which 95, 95 are shown in Fig. 5

I will now describe mechanism which l preferably use for connecting and disconnecting the engine to the main differential gear 55, and the means for controlling the same. -Referring to Fig. 6, it will be observed that the forward end of shaft 61 extends slidingly through the main gear 55, which is suitably keyed to the shaft, and that the gear is held rotatably in position on the housing by the divided ring 59. lt will also be understood that if desired, any suitable anti-friction bearing may be provided in place of this simple ring, which is shown for the sake of simplicity. The rear end of the shaft is provided witha clutch member 97 adapted to engage clutch 98 on the engine shaft 99. The clutch member 97 at the rear end of the shaft is adapted to slide back and forth through an upwardly extending bracket 100 carried by a horizontal supporting frame 101 suitably secured to the rear of the differential housing 50 (and reinforced if desired in any suitable manner). This frame 101 is also provided with an intermediate bracket 102 having an opening through which the shaft 61 slidingly fits. T he shaft has a collar 108 rigidly secured thereto, and between this collar and the bracket 102 there is provided a compression spring 101 tend ing to thrust the shaft forward to disconnect the clutch members 97, 98. The shaft is further provided with a second collar 105 rigidly secured to the shaft and having a lateral projection 106 for purposes hereinafter mentioned. The shaft is also provided with threads 107 between this collar ,and the clutch member 97, and there is threaded on this portion of the shaft a nut 108 adapt-ed to travel back and forth on the threads 107 as the shaft is rotated. The collar, nut and thread constitute a part of the means for automatically disconnecting the motor after the engine shaft has made a predetermined number, say for example eight, revolutions. The nut 108 is provided with a depending lug 10Q-extending below the top ofl a locking plate or latch 110 secured'to ashaft 1111 suitably pivotedat each end in the main supporting frame 101. A coiled spring 112 tends to throw the plate ina verticalposition. rlhis plate extends upwardly toward the shaft 61 a sufficient heightl so that when the shaft 61 is thrown backward to move clutch member 97 beyond the rear end ofthe latch plate, the latchv plate, then in its upright position, extends above the lower edge of the clutch member so as to prevent the spring 104 from moving shaft 61 forward to release the clutch members until' the said latch or plate is tripped.

The following control apparatus is` provided for forcing the shaft G1 rearward to engage the clutch members 97, 98: Referring to Fig. 4, it `will be observed that there is also provided in the differential housing just above the actuating link 84, a member 113 the arms of which are provided with

sleeves

114, 114 adapted to slide along the

inner guide rods

79, 79 so thatA the member lllmay be moved across the differential housing guided on said rods. The

sleeves

114, 114 are adapted to be engaged by the inner ends of the sleeves. 81, 81 secured to the Vcam members 80, S0', So that if either cam member is moved toward the rear of the casing by its pull wire, one or the other ofthe sleeves 114:, 114 is engaged, thus causing the slide member 118 to, be moved rearwardly with the said cam member. This slide member 113 is provided with an upwardly and forwardly extending bracket 115 (see Figs. 4 and 6) having a centering pin 116 carriedrat its upper end adapted to fit into the bored-out forward end of the sha t G1 when the slide member 113 is moved to the rear of thecasing. By this mechanism whenever one of the

pull wires

86 or 80 is operated to move one ofthe cam mem bers S0 or S0', the slide member 113 is moved rearwardly of the casing 50, and as the upper end of the bracket 115 engages the forward end of shaft 61, it forces the shaft rearwardly against the compression of spring 104. engaging clutch members 97, 98 to clutch the shaft to the engine. The construction and movement of the slide member 113 and of the cam members S0, 80 are preferably such that the cam member opcrates to clutchV the differential bevel to the differential shaft before the shaft 61 is thrust rearwardly sufficiently to close the Aclutch 97-98 to the engine shaft for rotating the differential shaft.

.E1n order to reverse the rotation lof shaft 61 after the engine has been unclutched the coiled-spring 11'7 is secured at one end to the hub of themain bevel gear 55, and at its other end tothe housing 50. When the operator pulls lever S7 to the left, he pulls on wire SGthus drawing cam member S0 to the rear ofthe differential casing, which in turn closes the clutch G2, for connecting bevel gear 54 to the differential shaft. The pull on wire 8G also causes the sliding frame 113 to move rearwardly, thus thrusting the clutch shaft 61 (see Fig. 6) rearwardly against spring 104 to close clutch 97-98 to the engine, whereupon the differential. shaft is driven from the engine against the direction indicated. The minute that the clutch members 97-98 become engaged to cause clutch shaft 61 to rotate, the nut 108 being held from rotation by engagement of its depending portion 109 with the latch 1.10. immediately commences to travel forward on the threads 107. llVhen the shaft G1 has made a certain number of revolutions, for example eight, the said traveling nut 108 is brought up against collar 105, whereupon lateral projection 105 from said collar engages projection 108 from the nut and thereby knocks it around, causing the projection 109 of the nut to strike the locking plate 110 and swing it on its axis down against spring 112 until it clears the lower end ofthe clutch member 97, whereupon spring 104 immediately thrusts the shaft 61 forward .into the position shown in Fig. 6, thereby unclutching the engine from the differential shaft-` The forward movement of shaft G1 also thrusts slide member 113 forward in the differential housing, thereby forcing the said cam member 80 and actuating lever S4 to their neutral positions; the movement of lever 84 also forcing the control lever S7 to its neutral position. As soon as the sliding cam member 80 is thus thrown to its neutral position, it opens the differential gear clutch 62, whereupon the coiled spring 117 about the hub of the main differential gear rotates said gear in the reverse direction to that in which it is driven b v the engine. whereupon the threaded nut 10S travels backward on threads 107 until it again reaches the position shown in (S. which arrests the rotation of shaftI 61. and the clutch shaft and mechanism are again in position to be operated to be clutched to the engine shaft and to be automatically re leased therefrom after a predetermined number of revolutions. It will be seen that the 'coil spring 117 is autonnitically wound up when clutch 97-98 is closed.

lVhen lever S7 is swung to the right. it pulls on wire SG to throw the cam member S0 and also the slide member 113 tothe rear of the casing. thus closing clutch GQ and closing engine shaft clutch 974-98, whereupon the engine drives the differential shaft in the opposite direction. After the predetermined number of rotations of the sha ft G1, nut 108 will have traveled forward to engage projection 106 to again release the latch 110 for opening the engine clutch and for forcing the clutch shaft 61 forward te move the control lever S7 to its neutral position, whereupon the clutch 62 is also opened.

Referring to Figs. 1 and 7, the supporting housing 52 carried by side frame 47, is provided at the sides with supporting bearings for the differential shaft 30; and extending horizontally from said housing there is a cylindrical casing 122 the end of which adjacent the housing is fitted over an annular flange 123 extending from the housing. The casing 122 is provided at its rear end with grooves or guideways 124, and within the casing there is provided a slide block 125 carrying a series of pulleys 126. Rollers 127 are mounted between the slide block and the casing to run in said grooves, so that the block may be guided back and forth in the casing. rlhe housing adjacent the casing is provided with a stub shaft 12S secured to the housing by being passed through bores in the upwardly extending flange 123, and on this shaft are rotatably mounted a series of individual rotatable wheels or pulleys 129.

Between the slide block 125 and the upper end of the fiange 123 there is provided a relatively powerful compression spring 130 which exerts its force againstthe slide block 125 to move the same rearwardly in the casing 122. The slide block is normally held against the compression of this spring by a suitable wire or rope 132 secured to t-he slide block and passing successively over one of the pulleys 129 on the shaft and over one of the pulleys 126 on the slide block, and finally passing between two guide rollers 133 secured to the housing, and from thence onto the drum 134 onto which it is wound and its end secured. rilhis drum, as shown in Fig. 10, is rotatably mounted upon a sleeve 135 which in turn is keyed to the differential shaft 30 so as to rotate therewith, and free to slide back and forth thereon, and the drum. is held from sliding off the sleeve by any suitable means such as a pin 136 carried by the drum 134 and coacting with a circumferential groove 136 in the sleeve 135, so that the drum and sleeve may slide back and forth along shaft 30 during the winding of the rope on the drum when the spring is being compressed, and the unwinding of the rope from the drum when the spring is extending. The drum is provided with a flange 137 having a projection 133 upon which is pi votally mounted a dog 139 the nose of which is held pressed inwardly by spring 140 against shoulder 141 cut in the flange of the sleeve 135 so as to hold these two normally locked together from relative rotation. The housing is provided at its right-hand end with an inner projection 142 (see Fig. 8), so located that when the drum 134 is moved to its extreme position to the right (at which the spring would have been coiled to its desired eX- tent), the projection will be in the path o1 rotation of the dog so as to strike the tail of the same to release the nose of the dog from the shoulder 141 and thus unlock the drum and sleeve to prevent overwinding of the spring, as hereinafter described.

Without considering for the present the mechanism for governing the starting device and its connection to the engine, it will be seen that with the spring compressed as shown in Fig. 7, if suitable means be provided for locking shaft 30, but for releasing the same when it is desired to start the engine, the extension of spring 130 will pull on the drum 134 which, being locked to the sleeve 135 by the dog 139, which sleeve is in turn keyed to shaft 30, will cause the shaft to rotate in the direction of the arrow shown in Fig. 7 to drive shaft 30l which, when clutch 62 is closed by the control mechanism heretofore described, will cause the engine to be turned over to start the same. During this movement the drum will move toward the left from the position shown in Fig. 7. It will be furthermore understood that when the engine is rotating the shaft 30 against the direction shown by the arrow in Fig. 7 this movement will rotate drum 134 to compress spring 130, during which movement drum 134 is moved toward the position shown in Fig. 7 and if the rotation of shaft 30 should continue after the spring has been compressed to the desired extent, the drum 134 will be in the position shown in Fig. 7; and if the rotation is continued, the tail of dog 139 will strike projection 142, releasing the nose of the dog from shoulder 141, thereby allowing the spring to momentarily rotate the drum 134 in the direction shown by the outer arrow in Fig. 8, during which time the continued rotation of shaft 30 rotates sleeve 135 in the opposite direction. As a result of this, after the drum and sleeve have been rotated in opposite directions each for apart of a revolution, the nose of the dog will again engage shoulder 141 to `lock the sleeve and drum together; but if at'this time shaft 30 is continuing to rotate, the tail of dog 139 will again be brought into engagement with projection 142, which will cause the drum and sleeve to be again released, and so on as long as shaft 30 continues to rotate after the spring has been completely compressed.

1 will now describe the locking device for shaft 30 and the means for releasing the same when it is desired to start the engine from the starter. Referring to Figs. 2 and 3, it will be seen that within the differential housing 50 a gear 145 is keyed tol shaft 30, and this gear meshes with gear 146 keyed to shaft 147 journaled on an upright frame or bracket 148 extending up `from the floor of the said housing. `Thesetwo gears are desirably chosen with the ratio of 1 to` because the differential gears 55, 54 are chosen with the ratio of to 1, the object being that for every complete revolution of the engine shaft, the shaft 147 carrying gear 146 will make one complete revolution. Normally gear 146 and hence shaft. 30 are held from rotation-by a latch 149 adapted to engage ratchet shoulder 15() formed on ine-niber'150 secui'ed to shaft 147. The latch is hung or swiveled on a pin 152 carried by a bracket 153 from the upper part of the differential housing. latch toward shaft 147, in position to be engaged by shoulder 150. The shaft 147 has also secured thereto /a substantially radial arm 151 adapted to engage pin 154 on lever 84 to force lever 84 and the parts movable therewith to neutral position after a predetermined amount of rotation of shaft 30 by the starter, as hereinafter more fully explained.

Then it is desired to start the engine, the operator swings lever 87 (see Fig. 5) to the right to pull wire 86', the pulling of this wire will rock actuating link 84 on its pivot 85 to move the cam member SOand sliding member 118 as heretofore described, for closing the engine shaft clutch 97-98 and also clutch 62 to connect gear 54 to the differential shaft; but the swinging of link 84 `also causes the left-hand end thereof to swing forward in the differential housing, thereby bringing projection 84 thereon (see Figs. 3 and 4) into engagement with the lower end of latch 149 so as to release the latch from ratchet shoulder 150. and gear `niemiber 150 but not to move lever 84 and its connected parts back to neutral position. In view of the ratio of the v gearingl as above mentioned, the engine shaft will, during the same time, have made substantially one coni-Y plete revolution. If this is not sufficient to start the engine, the operator moves lever 87 back to the right to cause projection 84 to again release latch 149 whereupon the engine is driven. by the starter through substantially a second revolution. This opera tion may be repeated as many times as may be necessary to start the engine.

The spring 180 may be compressed by the engine by moving the lever 87 (Fig. 5) to the left thereby pulling on Wire 86 and Spring 155 forces the causing cam 80 to close clutch 62 and clutch 97-98, whereupon the shaft 30 is rotated by the engine in a direction opposite that indicated by the arrows in Figs. 2 and 7, thereby causing the spring 130 to be compressed. Upon the automatic opening of the clutch 97-98, as explained, the lever 87 is automatically moved back again to its central or neutral position. Overcompression of the spring 160 is, as heretofore explained, avoided by the ratchet connection and release mechanism described in connection with the drum 134.

j `If at any time it is desired to compress the spring manually, this is accomplished by ratchet-wheel 165 (see Figs. 7 and 11), keyed to shaft 30 at the inner end of the casing 52, which ratchet-wheel may be rotated `by a lever 166 rotatably mounted on shaft 30 and carrying a pivoted pawl 166 arranged to co-act with the teeth of the ratchet-wheel 1 65. A detent pawl 166, which may be pivoted to the housing 52` and is arranged to co-act with the teeth of the ratchet-wheel 165, is provided to prevent rotation of the shaft 30 by the spring 130 during the operation of the lever 166. When the spring is sufficiently wound, the detentpawl 166 and the pawl 166 are moved out of operative position with respect to the teeth of the ratchet-wlieel 165, the shaft 30 being normally held against rotation by the engagement of the latch ratchet-shoulder 150.

I have also provided means for starting the car motor from the seat of the vehicle in the event that for any reason the starting device described should be broken or otherwise get out of order. This device consists of a ratchet 168 mounted at the right-hand end of shaft 30 (see Figs. 7 and 9). Adjacent this ratchet wheel an operating lever 169 is swiveled on the endof shaft 60 by means of a sleeve 170 fitting over the shaft. This lever carries a sliding ratchet bolt 171 guided by suitable guides 172 on the lever 169, and between one of these guides 17 2 and a collar 173 secured to the bolt, there is provided a compression spring 174 for moving the bolt out of engagement with the ratchetwheel 168. The upward throw of the bolt is limited byl a second collar 175. The lever 169 is normally held in the position shown in Fig. 9 by a coiled spring 17 6 connected at one end to the lower end of the lever and at the other end to a bracket 177 on casing 122.

149 with the To the upper end of the lever there `is pivoted a bell crank lever 178 one end of which is adapted to rest against the head of the bolt 171, and to the other end of this bell crank lever is secured a wire 17 9 running to the dash, so that when the operator pulls on this wire he holds the bolt firmly in engagement with the ratchet and moves the lever in a direction to turn the ratchet and shaft 30 through a part of a revolution to start the engine. It it docs not start on the :first movement ot the lever, the operator releases Wire 179, thus permitting the spring 176 to throw the lever forward, whereupon if wire 179 is again pulled, the shaft 30 is moved through another part of a revolution, and so on until the engine is started.

It will also'be obvious to those skilled in the art, after having understood my invention, that various changes and modifications may be made therein without departing from the spirit or scope ot the invention, and'I aim in the appended claims to cover all such modifications.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
