ACTUATING MECHANISM FOR AUXILIARY ENGINE UNITS.

Application filed` December 22, 1925. Serial No. 77,158.

This invention relates to devices for actuating the pump, magneto and distributor from the internal combustion engine with which they are associated. To attain the highest efliciency in the operation of the respective units they must each be driven at a different speed. The present invention has for one of its objects to incorporate the driving mechanism for the various units into a single structure which shall be accessible, easily replaceable, compact and practical and by Which the respective units shall be driven at a speed conducive to their efficient operation. Accordingly, the shafts of the various units are suitably coupled to inde pendent shafts journaled in a housing Which may be removably mounted on the engine and which may support the various units. The shafts may be driven, one from another, by gearing so proportioned as to obtain the requisite speed of rotation for each unit. A further object of the invention is to provide driving mechanism for the units Which may be readily assembled and disassembled. To this end the bearings for the respective shafts are removably mounted in openings in the housing and covers or caps are so arranged as to permit the removal of the shafts When desired.

In order that the invention may be clearly understood the same Will noW be described more fully With reference to the accompany ing drawing illustrating a preferred embodiment thereof and showing partly in side elevation and partly in vertical section driving mechanism for a pump, distributor and magneto incorporated as a unit in a housing which may be supported from the engine and Which may in turn support the various auxiliary units.

An engine to which the driving mechanism according to the present invention may be applied is not illustrated in the drawings, but a spiral gear rotated by such engine is shown at a and from this spiral gear the actuating mechanism for the pump, distributor and magneto is driven. It is proposed to incorporate the driving mechanism as a unitary structure in a housing'indicated as a Whole at t). The housing is provided with a flange h by Which it may be removably secured to the engine adjacent the gear e. The pump is carried directly on the housing by means of the flange The pump is not shown but a fragmentary por- `bearings j,

tion of its rotor shaft is indicated at c Which is coupled to what may be termed the first shaft Z `iournaled in removable bearings e, in the housing Shaft Z is driven from the spiral gear 0. by a spiral gear g Which is keyed to it and which is so proportioned as to cause the rotation of the shaftfl at the most efficient speed for the operation of the pump. The magneto 7a. is shown as carried upon a bracket t integral with a closure b for the opening b5 through Which shaft (l and the bearings may be removed from the housing. The magneto is operatively connected as by a flexible coupling y7i. with a second shaft el also journaled in removable in the housing h, this shaft being remou'tble by axial movement to the left, as viewed in the drawing, through the opening Z9 closed by the cap If. The magneto is driven at a higher rate of rotation than the pump. Consequently the spiral gear Z carried with shaft e' which meshes With gear g is of a smaller' vdiameter than gear g so that the ratio is such as to obtain the requisite higher speed. The opening o8 through which shaft 71 extends for engagement with the coupling 71. may be closed by an extension o integral with the bracket If a distributor' m is also to be driven. by the driving mechanism it may be rcmov ably secured to a flat surface b9 at the top of housing b and the distributor shaft m may extend downwardly into a Well h1@ Within the housing to be rotated from one of the shafts, say shaft z'. The end of shaft m. carries a spiral gear n, meshing With a spiral gear o carried on a sleeve o keyed to shaft e' and these tivo gears may be so proportioned as to obtain the desired speed of rotation for the distributor. If any one of the auxiliary units, for instance, the distributor, is not to be driven from the driving mechanism, a cap may be substituted therefor and secured, as by the boit m2.

In disassembling the driving mechanism after the driven auxiliary units are removed either before or after the housing has been removed from the engine structure the closures and 57 are removed. Shaft ai may then be moved axially to the right through the opening h5, the bearing also passing through the opening and the shaft passing through the gear g, the key d passing along the keyvvay g. After the shaft is clear of the gear the gear may be passed downwardl vout of the housing through the Well 111. haft' is similarly removed by moving `it to the left, being disengaged from the gears 1l and 0 in a manner similar to the disengagementof shaft cl. To remove the distributor it is, of course, merely necessary to disengage bolt m2 and raise the distributor in vertical direction thereby drawing the shaft m and gear a out of the well blo through the opening through which shaft m enters.

By the construction described various auxiliary units associated with an internal combustionengine may be driven at a predetermined speed conducive to efficient operation and the actuating mechanism is incorporated vinto a compact, easily demountable, unitary structurewvhich is supported i removably from the engine and in turn supports the respective units.

The invention has been described a" associated with the pump, distributor and magneto of an internal combustion engine but obviously devices other than those enumerated maybe driven by the mechansm.

Various modifications in the arrange ment and proportion of parts Will occur to those skilled in the art and no limitation in the use or the combination of elements is intended by the foregoing description and illustration except as indicated by llal accompanying claim.

Vhat I claim is:

In a driving mechanism for auxiliary de vices including pump, magneto, and distributor drive shafts, Va unitary housing supporting said shafts, means for securing the housing removably to the housing of a power source, means to support the pump shaft removably `in the housing, a gear earried by the pump shaft and engaging the power source means to support the magneto shaft removably in the housing and parallel to the pump shaft, a. gear on the magneto shaft meshing With the gear on the pump shaft, means for supporting the`distributor shaft removably in the housing at right angles and offset with respect to the magneto shaft, means to drive the distributor shaft from the magneto shaft, a removable cap on the housing providing access to the magneto shaft, and a removable closure for the opposite side of the housing, said closure providing access to the pump shaft and a bearing` for the magneto shaft and having an extension for mounting the magneto, whereby the entire assembly is mounted as a unit.
