Definitions
- a starter which, under-the above circumstances, will not have its pinion come out of mesh from the flywheel and which, therefore, will not have to repeatedly accelerate the flywheel from rest to crankin speed.
- t e pinion When once manually engaged, t e pinion will not disengage except under the control of the operator but it will permit the engine to run ahead by reason of its automatic clutching action.
- This starter will always go into proper mesh and will absorb the shock of starting the engine when full power is applied to the motor and engagement is made with a stationary engine.
- An engine driven member or gear 3 is shown in proximity to shaft 2. This gear 3 is usually mounted on the flywheel of-the engine.
- a control member 4 is mounted on shaft 2 for longitudinal motion thereon, but
- the nut 8 is prevented from coming off the control member 4 by means of the spring ring 27 located at the left-hand end of the threads on the control member.
- a spring 9 is provided within the barrel between the pinion 5 and the nut 8.
- the driving member 5 is mounted directly on the shaft 2 in axial alignment with the control member, and is movable longitudinally and rotatably on the is also placed between the flange10 and flange 11 and is also provided with teeth fitting be tween the teeth of pinion 5.
- v ' The control member has a groove 13 into which fits a spring pressed lever 14. The lever 14 is de: signed to be moved manually (either by foot or hand), and this moves the control member 4.
- This lever 14 is shown as having a contact plate 15 insulated from the lever and arranged to connect the stationary contacts 16 together to complete the circuit between the motor 1 and the source of current 17, when the lever is moved about its pivot 18 to move the control member 4.
- the control member 4 is threaded at the end away from the groove 13, and the nut 8 is mounted on these threads.
- a plate 8' having a cylindrical portion 8 is mounted on the nut 8.
- the cylindrical portion 8 is split so as to form spring fingers whereby the plate 8 is held in frictional engagement with the nut 8.
- the outer edge of plate 8' has projections fitting in slots in the barrel 7 and is thereby prevented from rotating with reference to the barrel.
- the clutch 6 comprises a plurality of cooperating elements 19 and 20, the element 20 being a driving element and connected to the barrel 7 for rotation therewith by means of projec tions fitting in the slots in the barrel.
- the portions of the slots in the barrel in which the projections of the plate 8' move are narrower than the portions of the slots in which the projections of the element 20 fit and thus shoulders 26 are formed against which the element 20 abuts at one .side thereby limiting its longitudinal motion in one direction.
- the clutch elements 19 are shown as comprising cork disks and punched metal clutch reta'iners, which are pressed into the cork disks and have slight projections 21 which enter holes in the clutch element 20. With the parts in the out-of-mesh position, shown in the drawing, the flange 22 of nut 8 is spaced away from the adjacent clutch element.
- I provide metal clips 23 which enter the elements 19 and prevent them from coming out of driving relation with the driving element 20.
- the barrel 7 is closed at the end away from the inion 5 by a cover 24 which is held in place y a snap ring 25.
- the cover 24 also engages the outer end of plate 8' and prevents it from moving longitudinally.
- the clutch elements are necessarily gradually pressed together, and consequently the clutch takes up the shock of starting the engine.
- the motion is transmitted back through the barrel 7 to'clutch element- 20 and the friction between the plate 8 and nut 8 is sufiicient to cause the nut 8 to move with the barrel and to back off slightly from the clutch, releasing the same.
- the engine drives the pinion 5 and clutch member 20, but the drive Will not be transmitted to the armature shaft 2, the plate 8 rotating on the nut 8.
- the operator can therefore take a reasonable length of time in releasing the lever 14. If the start is a false one, and the engine member 3 ceases to be propelled by the explosions in the cylinders, and the operator has not released the lever 14, the clutch will again become tightened, as explained above, and the operation of cranking will start again.

STARTING APPARATUS Fild Aug. 16. 1922 Inventor- 2 Joseph Bi ur, y
His Atibor-hey Patented Oct. 18, 1932 UNITED STATES PATENT OFFICE I JOSEPH BIJ'UR, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS, T0, ECLIPSE MACHINE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK STARTING APPARATUS Application filed August 1 6, 1922, Serial No. 582,221. Renewed February 28, 1925 occur in all of the cylinders in proper firing order particularly in cold weather, but take place irregularly here and there among the cylinders. Such individual. explosions momentarily drive the flywheel forward after which the engine may stop altogether because the explosions have not occurred continuously in proper order. The acceleration of the wheel causesthe usual type of automatic starter to disengage its pinion from the flywheel so that when the engine comes to rest, it becomes necessary to reengage the starting motor with the flywheel thus using the battery to again accelerate the engine from rest to the speed of cranking. In cold weather this occurrence is often repeated many times before the engine fires? regularly enough to run.
invention relates to a starter which, under-the above circumstances, will not have its pinion come out of mesh from the flywheel and which, therefore, will not have to repeatedly accelerate the flywheel from rest to crankin speed. When once manually engaged, t e pinion will not disengage except under the control of the operator but it will permit the engine to run ahead by reason of its automatic clutching action. This starter will always go into proper mesh and will absorb the shock of starting the engine when full power is applied to the motor and engagement is made with a stationary engine. Although my mechanism embodies the advantages of an overrunning clutch, these are attained without the use of the usual rollers and inclined surfaces used in the construction of such clutches which may not always be sure to operate when the lubricant with which they are kept oiled gets hard as it does in cold weather.
The various features of novelty which characterize my invention are pointed out in the claims annexed to and forming a part of this specification. For a better understanding of my invention, however, reference may be had to the following description taken in connection with the accompanying drawing in which the single figure represents a motor provided with an embodiment of my invention.
Referring to the drawing, there is shown a starting motor 1 ofthe usual type driving a shaft 2. An engine driven member or gear 3 is shown in proximity to shaft 2. This gear 3 is usually mounted on the flywheel of-the engine. A control member 4 is mounted on shaft 2 for longitudinal motion thereon, but
connected-thereto so as to rotate in unisonwith the shaft. This may be accomplished in any well known manner, and in the drawing this portion of the shaft vis squared, the control member having a square hole fitting over the squared portion of the shaft. A nut 29, with lock washer 30, prevents the control member 4 from being moved off of the shaft 2. A driving member or pinion 5 is also mounted on the shaft and is adapted to cooperate with the engine driven member. Torque transmitting means is provided be-. tween the control member 4 and the drivin member 5, including a clutch 6, a barrel T cooperating with the clutch and the driving member, and a nut 8 threaded on the control member and arranged to move to tighten the clutch when the motor 1 drives the shaft 2, as will be hereinafter explained. The nut 8 is prevented from coming off the control member 4 by means of the spring ring 27 located at the left-hand end of the threads on the control member. A spring 9 is provided within the barrel between the pinion 5 and the nut 8. The driving member 5 is mounted directly on the shaft 2 in axial alignment with the control member, and is movable longitudinally and rotatably on the is also placed between the flange10 and flange 11 and is also provided with teeth fitting be tween the teeth of pinion 5. v 'The control member has a groove 13 into which fits a spring pressed lever 14. The lever 14 is de: signed to be moved manually (either by foot or hand), and this moves the control member 4. This lever 14 is shown as having a contact plate 15 insulated from the lever and arranged to connect the stationary contacts 16 together to complete the circuit between the motor 1 and the source of current 17, when the lever is moved about its pivot 18 to move the control member 4. The control member 4 is threaded at the end away from the groove 13, and the nut 8 is mounted on these threads. A plate 8' having a cylindrical portion 8 is mounted on the nut 8. The cylindrical portion 8 is split so as to form spring fingers whereby the plate 8 is held in frictional engagement with the nut 8. The outer edge of plate 8' has projections fitting in slots in the barrel 7 and is thereby prevented from rotating with reference to the barrel. The clutch 6 comprises a plurality of cooperating elements 19 and 20, the element 20 being a driving element and connected to the barrel 7 for rotation therewith by means of projec tions fitting in the slots in the barrel. The portions of the slots in the barrel in which the projections of the plate 8' move are narrower than the portions of the slots in which the projections of the element 20 fit and thus shoulders 26 are formed against which the element 20 abuts at one .side thereby limiting its longitudinal motion in one direction. The clutch elements 19 are shown as comprising cork disks and punched metal clutch reta'iners, which are pressed into the cork disks and have slight projections 21 which enter holes in the clutch element 20. With the parts in the out-of-mesh position, shown in the drawing, the flange 22 of nut 8 is spaced away from the adjacent clutch element. In
- order to hold the clutch elements 19 loosely to each side of the driving element 20, when the parts are in the position shown in the drawing, I provide metal clips 23 which enter the elements 19 and prevent them from coming out of driving relation with the driving element 20. The barrel 7 is closed at the end away from the inion 5 by a cover 24 which is held in place y a snap ring 25. The cover 24 also engages the outer end of plate 8' and prevents it from moving longitudinally.
Normal 0peraf2'0n.The lever 14 is moved about its pivot 18 and by engagement with the groove 13 moves. the control member 4 along the squared portion of shaft 2. The control member through the nut 8 and spring 9 moves the pinion 5 into mesh with the engine driven gear 3, the barrel 7 moving with the pinion 5. 'hen the lever 14 has moved to the position where the pinion 5 and gear 3 are in full mesh, the contact 15 closes the cir that it moves backward until its flange 22 squeezes the clutch elements 19 and 20 together with sufficient force to cause the barrel 7 to rotate the pinion 5 and thus impart motion to the engine driven member 3. Power is now transmitted from the shaft 2 through control member 4 to clutch 6, to barrel 7 through clutch element 20, then from the barrel to pinion 5 and finally to engine driven member 3. It will be noted that the clutch elements are necessarily gradually pressed together, and consequently the clutch takes up the shock of starting the engine. Vhen the engine starts under its own power the en ine driven member 3 tends to drive the pinion. The motion is transmitted back through the barrel 7 to'clutch element- 20 and the friction between the plate 8 and nut 8 is sufiicient to cause the nut 8 to move with the barrel and to back off slightly from the clutch, releasing the same. Under these conditions, the engine drives the pinion 5 and clutch member 20, but the drive Will not be transmitted to the armature shaft 2, the plate 8 rotating on the nut 8. The operator can therefore take a reasonable length of time in releasing the lever 14. If the start is a false one, and the engine member 3 ceases to be propelled by the explosions in the cylinders, and the operator has not released the lever 14, the clutch will again become tightened, as explained above, and the operation of cranking will start again.
When the operator releases the lever 14, it through its spring (not shown) moves the entire mechanism to the position shown in the drawing, wherein the pinion 5 is out of mesh with gear 3 and the contacts 16 are open. If backfire occurs, the engine tends to drive the pinion 5 and barrel 7 in the opposite direction to that which the motor tends to drive these parts. No damage to the mechanism or motor will occur as under these conditions the clutch 6 will slip, permitting the pinion and barrel to rotate in the opposite direction to the motor, the shaft 2 and the parts mounted on the shaft 2. since the clutch 6 is designed to slip under a torque value greater than the stall torque of the motor, but less than the torque transmitted backwardly under backfire conditions.
Operation to enforce meslz2'ng.If, when the lever 14 is moved for the purpose of meshing pinion 5 with gear 3, the teeth of the pinforced as follows: The pinion now .being prevented from longitudinal and rotary motions, continued pressure on lever 14 moves the complete shift with the exception of pinion 5 toward the gear 3, the barrel slipping over the pinion teeth. In this way the spring 9 is compressed between the flange 10 on the pinion and the plate 8 on nut 8. Finally,
' the mechanism is moved sufliciently far toward the gear 3 so that the contacts 16 are closed and the motor is energized, rotating the shaft and control member 4. The other parts are still held stationary because of the friction between the end of the teeth of pinion 5 with the end of the teeth of gear 3, which is transmitted directly to the barrel 7 and clutch element 20 and indirectly through spring 9 to the nut 8. Control member 4 therefore screws into nut 8, causing nut 8 to tighten the clutch 6. Torque is now transmitted from the motor to shaft 2, control member 4, through clutch 6 to barrel 7, by
means of clutch element 20, thence to pinion 5, thus rotating the pinion 5. The instant the teeth of pinion 5 are turned into proper alignment with the spaces between the teeth of gear 3, compressed spring9 will expand rapidly to urge the pinion into full mesh with gear 3, after which normal operation takes place. Plate 28, acts, under these conditions, to deaden any noise due to the snapping of pinion 5 into mesh.
