WIIiFRIID THOMAS REID, OF BRISTOL, ENGLAND, ASSIGNOR TO THE BRITISH &' COLONIAL AEROPLANE COMPANY LIMITED, 0F BRISTOL, ENGLAND.

INTERNAL-COMBUSTION ENGINE.

Application filed July 17, 1918. Serial No, 245,376.

To all whom it may concern:

Be it known that I, WILFRID THOMAS REID, a subject of the King of England, residing at Bristol, England, have invented certain new and useful Improvements in Internal- Combustion Engines, of which the following is a specification.

This invention relates to internal-combustion engines.

The object of the present invention is the construction of an internal-combustion engine wherein the auxiliaries can be actuated by very simple gearing and wherein they can be conveniently arranged and can have their weights and their bulk symmetrically disposed at opposite sides of the longitudinal center-line of the engine.

According to the present invention there is combined with an engine of the type in which the main drive is taken from a principal single or tWin gear-wheel in the middle of the crank-shaft, a subordinate gear-wheel also in or about in the middle of the length of the crank-shaft, and to this subordinate gear-wheel (or instead, if desired, to the main gear-wheel or one of them) is geared a series ofsecondary shafts. The secondary shafts are parallel to one another, and lie one above another, and preferably in a vertical plane common to them all, and they are all transverse to the engine crank-shaft, and are supported in bearings in the engine. They are geared to the engine crank-shaft. One of them may be above that crank shaft and geared directly by helically-toothed gear-wheel on that secondary shaft to another helically-toothed gear-Wheel at rightangles to it and fixed on the engine crankshaft. Another of the secondary shafts (herein for convenience alluded to as the second) may be immediately below the engine crank-shaft, and can similarly gear directlywith the helically-toothed wheel on the latter- A third shaft of the secondary shafts may -be below the second and there maybe a fourth and fifth below the third. Of the third, fourth and fifth secondary shafts each has a helically-toothed wheel fixed upon it; that on the fi'fth is in the same plane as and gears directly with that on the fourth, while that on the fourth is in thesame plane as and gears directly with that on the third, and that on the third is in the same plane as I Specification of Letters Patent.

and gears directly with that on the second. Thus there need be only six gear-wheels for the five secondary shafts, i. e. five on those shafts and one on the crank-shaft.

- The accompanying drawings illustrate an internal-combustion engine with the present invention applied thereto. In these draw- 111gs Figure 1 is a longitudinal section of the engine, and I Fig. 2 is a transverse vertical section of Fig. 1; as to the left-hand half of Fig. 2 it is a section through oneofthe cylinders in Fig. 1, and as to the right-hand half it is a section through the middle of Fig. 1.

"In the engine illustrated the main drive is taken from a twin gear-wheel GW in the middle of the crank-shaft OS. A subordinate gear-wheel SGW is in the middle of the length of the crank-shaft being an instegral part of the boss 9w of the twin gear- Wheel GW which is a virtual continuation of the crank-shaft from one set of cranks G O C to the other set of cranks O C 0 To this subordinate gear-wheel is geared a series of secondary shafts 1, 2, 3, 4, 5. The secondary shafts are parallel to one another and lie above one another in a vertical plane directly with the helically-toothed wheel SGW on the latter by means of a helicallytoothed wheel 2 fixed on the shaft 2.

A third secondary shaft 3 is below the second and'geared .to the wheel 2 on the second shaft by the wheel 3 on the third secondary shaft 4, geared by a wheel 4: fixed upon it to the wheel 3 of the shaft 3 above, and geared below to a fifth secondary shaft 5 by the wheel 5 fixed to the latter.

At each end of the secondary shaft 1 is a magneto M, only one of these magnetos beshaft. Below the third shaft is a fourth, 1

. the two related parts of a lubricating-pump, I one part, a suction-device SD, drawing'from the sump S, and the other part, a pressuredevice ID, delivering into the lubrication circulation-system. The fifth shaft is geared I through the wheel 5. fixed to it, with the shaft 3 by way of the idler P on "shaft 4.

The construction illustrated for driving .centrally from the main crank shaft is claimed in my copending application, Se-

' rial No. 249,023, filed August 8, 1918.

What I claim as my invention and desire to secure by Letters Patent is .1. In an internal combustion engine, the combination with a crank shaft having a main driving gear wheel, of a subordinate gear wheel adjacent thereto, a series of secondary shafts extending transversely to said crank shaft and symmetrically on opposite sides of the engine, a secondary gear wheel mounted centrally on each of said secondary shafts and geared with said su'bordinate gear wheel, and auxiliary devices arranged in pairs with one device of each pair at opposite ends of each of the secondaryshafts and on opposite sides of the engine,

substantially as described.

2. In an internal combustion engine, the combination with a crank shaft having a main driving gear wheel in the middle thereof, of a subordinate gear wheel on the crank shaft adjacent thereto, a series of secondary shafts extending transversely of the crank shaft and symmetricallyon opposite sides of the engine, secondary gear wheels mounted one on the central part of each secondary shaft and intergeared with one another and with said subordinate gear wheel, and auxiliary devices arranged in pairs with one device of each pair atopposite ends of each of the secondary shafts on opposite sides of the engine, substantially as described.

3. In an internal combustion engine of the character described, the combination with a crank shaft of a main driving twin gear wheel in the middle thereof, a'subordinate gear wheel intermediate the parts of said twin gearwheel, a series of secondary shafts arranged transversely of the crank shaft and extending. symmetrically on opposite sides ofthe engine, secondary gear wheels mounted one on the central part of each secondary shaft and driven from said subordinate gear, and auxiliary devlces arranged in palrs of s1m1lar devices, one at each end of each secondary shaft and on opposite sides of the v engine, substantially as described.

In testimony whereof I affix my slgnature.
