- an engine starter motor such as at 10a, FIG. 6 and 7, which is constructed for cranking the flywheel, such as 18A, which is of a relatively smaller diameter.
- the adapter assembly 40 enables the drive gear 16A of the engine starter motor 10A to be positioned closer, such as a distance D from the axis of rotation 27 of the crankshaft 21, than is the drive gear 16 of the engine starter motor 10, such as the distance
- the body 26 includes a removable portion or knock-out 41 (FIGS. 2 and 9) which is disposed adjacent the opening 9 and results in an enlargement 43 (FIG. 5) of the opening 9 in a pre-determined direction upon selective removal of the portion 41 from the body 26.
- the knock-out 41 is formed out of the material of the body 26 being stamped out or otherwise severed therefrom.
- the knock-out 41 is defined in part by a segmental portion 46 of the marginal edge 48 of the opening 9 and in its remainder by a continuous cut 50 (FIG. 9) extending from one point 52 on the marginal edge 48 to another spaced point 54 on the marginal edge 48, thus defining a severed edge 51 for the knock-out 41 and a marginal edge portion 53 for the enlargement 43 of the opening 9 (FIG. 8).
- the knock-out 41 includes one part 56 which is displaced from the general plane of the body 26 and another part 58 (shown crosshatched in FIG. 9 for the purposes of illustration) which is generally co-planar with the general plane of the body 26.
- the displaced part 56 is displaced a distance, such as indicated by the dimension A, which is less than the thickness, as is indicated by the dimension B, of the body 26 so that when the knock-out 41 is intact on the body 26, the severed edge 51 remains in pressured engagement with the marginal edge portion 53.
- a diaplacement distance A equal to approximately 0.060 inches has been found to be quite satisfactory.
- the coplanar part 58 is retained in the general plane of the body 26 so as to provide clearance for the bellhousing flange, indicated by the phantom lines at 59, to enable flush engagement between the flange 52 of the bellhousing 6 and the block plate 2 when they are in the installed position as shown in FIG. 1.
- the entire knock-out 41 is initially stamped or otherwise displaced from the general plane of the body 26 the desired distance, such as the distance A, and then, the coplanar part 58 is restamped so as to be returned to the general plane of the body 26.
- Such restamping operation causes the material of the knock-out 41 adjacent the coplanar part 58 to be moved away from the material of the knock-out 41 adjacent the displaced part 56 thereby forcing the severed edge 51 into tight pressured engagement with the confronting marginal edge portion 52 for retaining the knock-out 41 connected to the body 26.
- a force such as a blow from a hammer or the like, can be applied to the knock-out 41, preferably in the direction of the displacement, to separate the knock-out 41 from the remainder of the body 26.
- the knock-out 41 is generally crescent-shaped, when viewedin front elevation, having its severed edge 51 extending generally arcuately between the points 52 and 54 on the marginal edge 48 and defining a major side for the knock-out 41 having a length longer than the opposite side defined by the segmental portion 46 of the marginal edge 48. Further, in this arrangement, the knock-out 41 is formed in the body 6 downwardly and inwardly with respect to the geometrical center of the opening 9.
- the block plate 2 can be used with the knock-out 41 intact with one type of motor starter, such as 8, having a drive gear 16 which is required to be positioned a predetermined distance, such as the distance C, from the axis of rotation 27 of the crank shaft 21 for driving a flywheel, such as 18, of one predetermined diameter.
- the coplanar portion 58 is shown having a bolt hole 63 (FIGS. 2 and 9) for receiving a fastener 65 (FIGS. 3 and 4) therethrough for mounting the starter frame 10.
- the block plate 2 can be used with the knock-out 41 removed with a motor starter, such as 8A, having a drive gear 16A which is required to be positioned at another distance, such as the distance D, which is radially closer to the axis of rotation of the crank shaft 21 for driving a flywheel 18A which is of a smaller diameter than the flywheel 18.
- a motor starter such as 8A
- a drive gear 16A which is required to be positioned at another distance, such as the distance D, which is radially closer to the axis of rotation of the crank shaft 21 for driving a flywheel 18A which is of a smaller diameter than the flywheel 18.
- the adapter assembly 70 is formed in a block plate 2A which has a body 74.
- the body 74 is shown as including an opening 76 which is adapted for receiving a portion of the engine starter motor (not shown) as hereinbefore described, and
- the adapter assembly 70 includes a removable portion or knock-out 80 which is disposed adjacent the opening 76 and which, when detached from the body 74, forms an enlargement 81 (FIG. 13) for the opening 76.
- the knock-out 80 is of a generally crescent-shape, as seen in front elevation in FIG.
- the knock-out 80 is positioned radially outwardly from the center of the opening 76 and the geometrical center of the body 74 such that the enlargement-81 is formed in the body in a direction outwardly and slightly downwardly with respect to the center of the opening 76.
- the knock-out 80 includes a displaced part 94 which is displaced out of the general plane of the body 74, such as a distance E, and a pair of spaced, generally coplanar parts 96 and 97 (which are also shown crosshatched for purposes of illustration) which extend outwardly from one another and outwardly from the opposite sides of the displaced part 94. It has been found that a displacement distance E equal to approximately 0.075 inches for a block plate having a thickness F (FIG. 13) equal to approximately 0.125 inches has resulted in a highly satisfactory performance.
- the entire knock-out 80 is stamped or otherwise displaced out of the general plane of the body 74, and then, the coplanar parts 96 and 97 are restamped so as to be returned to the general plane of the body 74.
- Such restamping operation results in spreading of the co-planar parts 96 and 97 causing them to move outwardly away from one another and away from the displaced part 94 such that the severed edge 90 of the knock-out 80 contacts the marginal edge 92 of the enlargement 81 in pressured engagement through substantially its entire length securely retaining the knockout 80 on the body 74.
- a force such as a blow from a hammer or the like, the knockout 80 can be removed from the body 74, when desired.
- the enlargement 81 is made in the direction of the peripheral edge of the body 74 and generally radially outwardly from the geometrical center of the opening 76 such that, when the knock-out 80 is intact, the block plate 2A is suitable for use with an engine having a flywheel with a diameter of one predetermined size, whereas, when the knock-out 80 is removed, the block plate 2A is adapted for use with an engine having a flywheel with a predetermined larger diameter.
- the restamping operation returns the coplanar parts 96 and 97 into the general plane of the body 74 which provides clearance and enables a flush, tight fitting contact between the block plate 2A and the bellhousing flange, the inner outline of which is indicated by the phantom line at 99.
