13 claims.

This invention relates to internal combustion engines and more particularly to engines of the Diesel type.

An object of this invention is to provide a novel and improved drive mechanism for a plurality of Diesel engine elements.

Another object of my invention is to provide a driving unit for a plurality of devices associated With an engine which can be readily attached and detached from the crank case.

A further object of the invention is to provide a plural drive and housing for elements cfa Diesel engine which can be utilized for application to either side of an engine so that two types of devices will not be required for use with engines disposed on two sides of a boat, for example, where it is desirable to have such mechanism on adjacent sides.

Other objects of the invention will appear from the following description, taken in connection with the drawings, which form a part of this specification, and in which:

Fig. 1 is a top plan view of an engine with which the invention is associated;

Fig. 2 is a side elevation of the same;

Fig. 3 is a vertical sectional View of the unitary driving mechanism taken on line 3-3 of Fig. 4;

Fig. 4 is a horizontal sectional View of the unitary driving mechanism taken on line 4 4 of Fig. 3;

Fig. 5 is another sectional view taken on line 5-5 of Fig. 3.

Referring now to the drawings by characters of reference, 10 indicates the crank case and 11 the bottom cover or pan of a Diesel type of inline engine through which the conventional crank shaft extends longitudinally. A multi-cylinder block 12 is secured upon the crank case, and side cover plates 13 extend between4 the head cover 14 andthe crank case in spaced relation from the sides of the cylinder block.

- The crank case 15 at one end of the cylinder block is enlarged, and secured to one wall thereof by the bolts 16 is a casing 17 for supporting and .carrying the compressed air distributer, the fuel oil pump and the tachometer. The attached end l.of the casing is formed with a central bearing 18 while the opposite end of the casing has a lbearing 19 detachably associated therewith. A drive shaft 20 having spaced helical gears 21 fixed thereon is carried by the bearings in the casing, such shaft being removable endwise from the casing when the bearing 19 is detached. The drive shaft extends into the crank case and is .provided with a gear 22 which is driven by gearing 1931. Serial No. 509,674

(Cl. 1Z3--195) in the crank case (not shown) actuated by the crank shaft or some other rotating engine element.

The casing extends parallel with one side of the crank case and is formed with similar parallel top and bottom walls having aligned openings 23 therein. The casing with the drive. shaft therein can be assembled with the crank case so that" either the top or bottom wall is uppermost, and therefore it can be applied equally well to either the right or left side of an engine. This arrangement is an advantage when a pair of engines are employed and related so that the mechanisms mustbe arranged on adjacent sides of engines, for example with a pair of boat engines where the apparatus is located on the inner sides thereof, because otherwise two casings of different form would be required.

A removable cap or plate 24 is secured over each of the openings 23 in the under wall of the casing by bolts 25 and bearings 26 extend therefrom into the interior of the casing.

Removable cap members

27, 28 and 29 are secured over the openings in the upper wall of the casing by bolts and are provided with hollow bearing portions 30 which extend into the casing and align with the bearings 26.

Stub shafts

31, 32 and 33 are carried by the aligned bearings and extend exteriorly of the -ca-p members .27, -28 and 29, while a helical gear` 34 is xed upon each stub shaft in a relation to mesh with the gears 21 on the drive shaft. Screwed upon the cap 27 is a tachometer casing 35 and the shaft 31 is associated to drive the revolution counting meohansim therein in the conventional manner.

A pump casing 36 is mounted upon the cap 28, and the stub shaft 32 extends into the casing for driving a conventional gear pump (not shown). This pump is connected with a source of koil supply by the conduit 37 and to the manifolds 38 on each side of the cylinders by the conduit 39. The manifolds 38 have a common overflow conduit 40 associated therewith for conducting excess fuel oil back to the source of Supply. Fuel injection devices 47 are associated with opposite sides of each cylinder to project fuel charges into the combustion chambers and are connected with the manifolds 38.

The cap 29 forms one section of a compressed air distributing casing and associated therewith to complete the casing is a housing 41. A conduit 42 leads into the housing and is connected with a suitable source of compressed air (not shown) which can be admitted to the `distributer when the engine is being turned over for starting. The stub shaft 33 extends into the distributer chamber and has fixed thereto a distributer plate 43 which is adapted to rotate just above a plurality of passages 44 leading one to each cylinder through the conduits 45. The plate is formed with an opening 46 which rotates over the passage openings so that compressed air charges will be released through the conduits to the cylinders in their ring order from the chamber into which the conduit 42 leads.

The tachometer, pump and distributer devices are detachable from the casing and can be assembled upon the

caps

27, 28 and 29 andl attached therewith to either wall of the casing. The caps or closures 24 are arranged to be secured to either wall of the casing. The entire assembly of the casing and the units detachably secured thereto can be detached from the crank case by removal of the bolts 16, the conduits associated with the pump and distributer, and the electric wiring associated with the tachometer.

The inner end of the distributer cap member 29 is formed with a flange 50 so that oil will be collected therein, and passages 5l establish communication between the collected oil and the shaft 33. The shaft is formed with a spiral recess 52 which will move oil from the passages along the entire length of the shaft bearing 53. The bearings for the

other stub shafts

31 and 32 can be lubricated in the same manner as the bearing 53 if desired.

It will be seen that the device described can be associated with either side of an engine through the rearrangement of the parts. The device, furthermore, is simple in design, pro- Vides a compact arrangement and is readily detachable as an entire unit from the crank case or as subunits from the casing.

While I have herein described in some detail a specific embodiment of my invention, which I deem to be new and advantageous and may specifically claim, I do not desire it to be understood that my invention is limited to the exact details of the construction, as it Will be apparent that changes may be made therein without departing from the spirit or scope of my invention.
