VINCENT IBENDIX, OF CHICAGO, ILLINOIS.
ENGINE-STARTER.
Application filed June 29, 1917. Serial No. 177,757.
To all whom it may concern:
Be it known that I, VINCENT BENDIX, a
citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Engine-Starters, of which the following is a specification. I
My invention pertains to a part of the organization of a starting device for engines such as explosive engines, and particularly to a part of the transmission or drive between the starting motor and' the engine to be started. According to present practice such an engine is generally started through the fly wheel by means of a pinion actuated in proper manner by the starting motor and meshing with 'teeth either cut on the periphery of the fly wheel or formed in a ring secured to such wheel. Broadly speaking the fly wheel-constitutes a rotatable member of the engine to be started and my invention consists in making such rotatable member in two parts having a relative yielding movement with respect to each other, one part being the fly wheel proper and the other a gear ring which is adapted to slide or slip peripherally on the wheel against the tension of a yielding pressure, such pressure being preferably exerted in both directions. By means of such a construction a yielding means or driving connection is provided between the starting motor and the wheel proper, whose motion is communicated to I the engine to be started.
In the drawing Figure 1 is an elevation of a wheel embodying my invention; Fig. 2 a detail plan of part of Fig. 1; Fig. 3 a detail elevation of a modified form of construction; Fig. 4 a section on the line 4-4 of Fig. 3; Fig. 5 a detail elevation of another modifiedform of construction; Fig. a section on the line 6--6 of Fig. 5. Fig. an elevation of one form of drive cooperating with the engine wheel; Fig. 8 an end elevation of the pinion and shaft thereof; Fig. 9 an elevation of another form of drive; Fig. 10 a section on the line 1010 of Fig. 9; Fig. 11 an elevation of a modified construction of engine wheel and-gear ring; and Fig. 12 a detail plan of a portion of said wheel and ring,together with one of their springs.
Referring to the embodiment of my invention as illustrated in Figs. 1 and 2, the rotatable member which is adapted to be connected directlyor indirectly with the en- Specification of Letters Patent.
Patented Apr. 8, 1919.
gineto be started is here shown as a fly wheel secured to the crank shaft 1 of the engine. This member comprises two parts, a wheel 2 and a ring 3 having gear teeth 3*. This ring is mounted to slide or slip peripherally of the wheel and by preference such ring is held with a yielding pressure against a peripheral flange or shoulder 2 on the wheel.
The ring is .held' in a normal position by virtue of a yielding means such as pairs of coiled springs 4, which also tend to resist relative movement or slipping ofthe ring in both directions and to restore such ring to its normal position relative to the wheel. These springs are pivotally connected to the ring and wheel at a plurality ofanchoring points, there being in the instance now being movement of the ring in either direction is resisted by the springs which also restore .the ring to normal position. As shown in Figs. 1 and 2, washers 7 are provided on the studs 5 which washers have the effect of retaining the gear ring in position with respect to its lateral movement, in which event, the angular disposition of the springs, as above described, may be dispensed with.
When power is first applied to the gear ring through a driving member such as the pinion a, the shock or initial movement is taken or absorbed by these springs, one member of each pair being extended and the other member being contracted. These springs are preferably assembled under tension, in which event both springs are active whichever the direction of rotation of the wheel and ring. The use of springs acting in opposite directions is of advantage to take care of the back lash, of the .ring which'occurs .when the driving load is relieved upon the.
demeshing of the pinion.
As'shown in Fig. 2 these anchoring points are in different planes, those on the gear ring being located in a plane farther out. .from
' pinion has a collar portion plane of the anchoring points on the wheel,
with the result that the springs have the additional function of holding the ring in place upon the wheel periphery and against the shoulder 2 thereof.
In Figs. 3 and 4, I have shown a modified form of construction, particularly as to the anchoring points and the angular relation of the springs of each pair. Vhile in Fig. 1 these springs are at an angle the same in Fig. 3 are in axial alinement. Moreover the common anchoring point 8is connected with the gear ring through the medium of a plate 9 secured to said ring, while the two separate anchorin points 10 are secured to or form a part of the wheel itself. According to this construction the common point 8 is the outermost one and the springs hold the gear ring in place against the shoulder 2 in the manner above described.
In Figs. 5 and 6, I have shown another modified form of construction, according to which the springs which are in axial alinement are connected at their outer ends to separate anchoring points 11 on the gear ring and at their inner ends to a link 12, which is pivoted at its center to a stud 13, forming the common anchoring point on the wheel. The functions of these springs are the same as those above described.
Different forms of drive between -the starting motor "and the engine wheel may be used, and in Figs. 7' and 9 I have illustrated two different forms of drive for such purpose.
Describing the drive shown in Figs. 7
and 8, the starting motor indicated at A has a driving shaft 14 which is here shown as an extended armature shaft, to which is secured by means of the pin 15 a hollow screw shaft 16, said two shafts being in addition and by preference splined to each other by means of the key 17. Upon this screw shaft is screw-threaded the pinion a, which, when the electric motor is started, and the screw shaft thereby rotated, automatically advances longitudinally and into mesh with the gear ring. When the engine starts on its own power the pinion is auto= matically demeshed.
In Figs. 9 and 10 the action of the pinion not automatic but is hand or foot operated. According to this construction the a adapted to be engaged by a shifter 18 for moving such pinion longitudinally ofgthe driving shaft 14 and into mesh with the-fly wheel. So far as my invention is concerned any other kind or type of drive may be employed.
It is preferable but not essential, broadlyin common, inasmuch as the springs may be separately located and secured to the wheel is shownin Figs. 11 and. 12, according to which the springs are arranged separately and in two sets indicated at 19 and 20, such sets being reversed. Preferably the corre sponding springs, that is, the springsacting in the same direction should be arranged equidistantly around the wheel and ring. Moreover, by preference. the springs are arranged at an angle to the plane and direction of rptation with the result that the ring is yieldingly held against both rotary and longitudinal movements, although this is not essential because of the presence-of the washers 7.
