Application filed March 8, 1921. Serial No. 450,707.

To all whom it may concern:

Be it known that I, EDWARD B. Nowosrnrsxr, a citizen of the United States, residing at Bloomfield, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Combined Collector and Terminal Blocks, of which the followin is a description, reference beie accompanying drawing and to the figures of reference marked thereon.

This invention relates to a combined collector and terminal block peculiarly adaptable to ignition current machinery.

An object of this invention is to provide a neat and compact arrangement for collecting and distributing ignition current.

Another object of this invention is to provide a block which may be mounted in the supporting plate of anigniter in any oneof several positions.

A still further object of this invention is to provide a block to which terminal cables may be quickly and-easily secured without the use of any tools.

Other and further objects will appear after reading the following specification and claims in conjunction with the accompanyingdrawings in which:

igure 1 is a front view of the supporting plate and block, a ortion being broken away to expose a part 0? the retainin means.

Figure 2 is an end view part y in section of the plate and block shown in Figure 1, a current distributing spool being shown in dotted lines.

Figure 3 is a fragmentar back view of the supporting plate and b ock, a portion being broken away.

Figure 5 isia view of the inside of the cover. a

Figure 6 is a section along the line 6, 6 of Figure 4. v

Figure 7 is a perspective view of oneof the pins which is embedded in the block. I

Figure 8 is a view of the block retaining spring rod, and

Figure9 is a plan view of the distributing spool.

According to my invention a supporting plate 1 is provided with a circular opening 2 in which ther projects a dowel tooth 3 adapted to engage in any one of a plurality of notches 4 in a moulded base block 5, having two substantially parallel faces 34 and 35, the face 34 being enclosed by a moulded cover 6. The notches are conveniently spaced 90 degrees apart, although any other spacing may be provided so that the cables 7 may extend from the block inany desired direction.

To retain the base block and its cover in adjusted position, a spring rod 8 having ends provided with eyes 31 is passed diametrically across and over the cover 6, said rod being retained in place by means of two pins 9 suitably reduced in diameter as at 10 in order to snap in place in the eyes 31 when the same are pushed in place in cars 11 which are cast integral with the supporting plate 1. To prevent any water leakmg between the base block and supporting plate into the "interior of the cover plate a felt gasket 12 held in place in a suitable groove '13 in the block 5 is interposed between the block and the supporting plate.

The cables are positioned in channels 14 moulded in the face 34 of the base block and are retained in place by the cover 6. For

this purpose the cover is provided with a rim 15 cooperating with a shoulder 16 on the base block, and carved out portions 17 in the cover cooperate with the channels in the base block. The base block is further provided with a projection '18 which cooperates with a notch 19 in the, cover to prevent rotative movement thereof. The channels 14 extend from the outer periphery'of the block to an inner portion thereof and at their outer ends are each provided with a rib 20 to cover is provide with a felt gasket 33 seated in a oove in the cover to make watertight connection with the base block. At the press into the sheath of the cable to Q form a watertight joint therewith. The

a brush holder 22. The assembled pin and brush holder is moulded into the base block with the brush holder imbedded in .a moulded portion 23 of the block so as to insure insulation between the brush holder and the edge of the supporting late. The brush holders extend substantia ly at right angles to the face 35 of the block instead of radially thereof, thereby insuring a compact-arrangement of the entire device. The brush holders are positioned near the edge of the block in the form of a regular polygon so as to obtain the greatest spacing possible between the brushes while'the pins are set in nearer to the center of the block so as to ELVOld breaking away of the moulded material from around the inserts. WVithin the holders are suitable spring pressed brushes 24, adapted to cooperate with a rotating spool 25 hav ng a metallic insert 26 in electrical connectlon with a brush 27 leading to a source of ignition current. A central stud 32 in the base block forces the spool home in its bearing. Since the spool forms no part of my present invention, no further description thereof 1s necessary herein. It is sufiicient to state that when the spool rotates current is fed from the source of ignition current through the brush 27 to the insert 26, thence in rotation to each of the brushes 24, the pins 21, the cables 7 the spark plugs and thence back to the source of current.

The supporting plate is provided with apertures 28 thru which securing means maly be passed, and a manually controlled spar lever 29 passing thru a bearing in the sup porting plate has a portion 30 adapted to 05'- cillate a portion of'a circuit breaker mechanism of the electric machine to advance and retard the spark as will be understood by those skilled in the art.

It will thus be seen that by merely forcing out one of the pins 9, the rod 8 may be swung aside toremove the cover from the block, or the cover and block from the supporting plate so as to remove or insert the cables 7, as desired. Whenthe cables have been pressed into place, the cover is applied to the base block, the whole is inserted into the supporting plate with the cables extendmg in any direction as required, the rod is swung over to clamp the block in lace, and the pm 9 is snapped into place in tEe ears-11.

With my present invention the base block may be so mounted on the supporting plate that the cables may extend toward the engine block irrespective of whether the electric machine is mounted to the right or left or above or below the engine block. After thabase block has been adjusted to proper position the cables are connected in the proper firing grder to the spark plugs.

I have thus provided a convenient and. neat arran ement for securing cables to a block which has the dual function of a terminal block and a current collector.

Having thus described my invention, what I claim is:

1. In a distributer block for an ignition generator, a base block having' a'pa rt extendblock, a base block ing within a supporting plate of said generator, said extending part having collector brushes mounted thereon, the part of said base block exterior to the supporting plate having an outer substantially flat face with a plurality of individual cable channels extending part way across said face, terminal elements positioned near the inner end of said channels and in electrical contact with said brushes, a cover serving to hold said cables in contact with said terminal elements and a clamp fastened to the generator supporting plate and extending across the face of said cover.
