To all-whom it may concern:

Be it known that I, HEINRICH SCHNEIDER, a citizen of the German Republic, and residing at Baden, Switzerland, have invented certain new and useful Improvements in Vehicles, More Particularly a Locomotive, with Combustion-Engine and Liquid Driving-Gear, (for which I have filed an application in Germany, April 14th, 1919,) of which the following is a specification.

The present invention has reference to a vehicle, more particularl a locomotive, with combustion engine and iquid driving gear. Itis a well known fact that, in order to overcome the initial difficulties attendant on propelling a vehicle, more particularly on starting a locomotive by means of combustion power, detachable couplings or liquid driving-gears are used. W on heavy work is to be done by a locomotive, the arrange ment and plac ng of the engines and the liquid drivingears affording the necessary number of revolutions and of an admissible weight is a task which presents very great difiiculties, as is also the work of transmitting force, from the motor to the drivingare empty gear and from the latter to the driving shafts.

The present invention relates to a vehicle, more particularly'a locomotive, with combustion-power engines and liquid drivinggear on the driving-shaft, in which the propulsion system, consisting of motors, me-

chanical transmission appl ances and primary parts of the liquid driving-gear 1s firmly embedded in the framework of the locomotive, whereby the secondary part of the gear,

scribed hereafter, as the principal motor can serve to fill the com ressed .air chambers when the train is stan ing still and the gears thus avoiding the use of large compressed air chambers and large auxiliary compressors necessary for direct pro ulsion.

Moreover a greater movability of t e driving-shafts is obtained by simple means whereas hitherto steam and especially electric locomotives have alawys had to be equipped with very expensive and very complicated constructions.

By means of the above described arrangement of the liquid driving-gears the whole of the space above the platform can be kept free for the combustion-power engines, auxiliary appliances and for the service of the locomotive.

As the primary shafts are firmly embedded, a rigid propulsion system between the motor, frames and primary shafts is obtained and as there is an elastic connection only between the driving-wheels and the motor and the frames, the shock coming motor can work by itself with the gears belonging to it and the other motors can stand still with their gears em ty.

Moreover, for examp e, when running down hill, the gear can be used as a brake; in such a case the motor is stopped or is used for filling the compressed air chamber.

Furthermore the gear permitsof reversing the combustion engine while the train is going forward.

The present invention can also be used for starting only; in this case the liquid drivinggear only works at the start, the and secondary parts of the gear bemg coupled together by means of any device, as soon as a certain degree of speed is obtained.

It goes without saying that the parts of the gear can be constructed in any way, together vwith the driving-wheels or the wheel rims.

My invention will be best understood, when described in connection with the accompanying drawings in which Figure 1,

primary Fig. 2 and Fig. 3 represent sections through the driving-shaft and liquid driving-gear of three examples of execution.

struction shown in Fig. 1 the motor-shaft transmits by means of appliances (not shown in the drawing) for example coupling rods, toothed wheels, etc., the work done by the motor to the primary axle 1 which is firmly embedded in the frames R, B. On this primary axle 1 are placed the primary parts of the liquid driving-gear 2, 2. The secondary parts of the driving- gear 1, 1 are placed on the secondary shafts 3, 3, which arefitted up as hollow shafts, together with the driver wheels 3", 3'. The secondary shafts are embedded in the frames R, R and rest upon springs. Movable stufiing boxes situated between the primary and secondary shafts prevent the liquid from escaping. The liquid is brought and carried off by the primary and secondary'shafts.

The driving gear shown in the drawings, consists of two blade-wheels, the driving wheel portions 2, 2, of which act in operation as pumps. while the driven wheel portions 4, 4, act as turbines; The respective wheel portions are not in contact, and the transmissio of power therethrough results solely through the flow of the liquid. The wheel portions may be provided with radial blades.

The invention is not concerned with a particular construction of liquid driving gear, but more particularly with .the arrangement of such gear on the driving shafts and the arrangement of such gear with the rest of the combustion engine locomotive driving parts.

According to the second example of construction shown in Fig. 2 a rigidly fixed shaft 6 transmits the work done by the motor to the liquid driving-gear by means of the toothed wheel 7 The secondary part 8 of the liquid driving-gear is built together with the driving-shaft 9, upon which the driving- wheels 10, 10 are firmly fixed and is inclosed by the two-part primary art 11, 11' of the gear. The latter is embedded in bearings 12, 12 and is rigid in the frame 13, 13'; the part 11' has a toothed-rim 1a which is in contact with the toothed-wheel 7 and is driven by the latter. The driving shaft 9 is embedded in bearings 15,15 which are provided with springs, in the frame 13, 13". The liquid driving-gear has clearance room on all sides and an arrangement of stufiing boxes 16, 16 and 17, 17 with radial movements, so that a radial and axial displacement of the driving-shaft is made possame.

The following devices are arranged for the purpose of filling and emptying the dra ing-gear.

Liquid is brought to the driving-shaft 9 through the pipe 18 and the joint and conducted into the hollow boss of the primary part through the axial bore 20 and radial apertures 21 from whence it enters the working-chamber through-openings 22. On the periphery of the gear-chamber there are arranged several pipes 23 which are fixed preferably at even intervals over its circumference. These pipes extend intothe chamber 24 between the two stufling boxes 16' and 17'. If the driving-gear is full, injected fresh water forces a part of the heated gear-water through the pipes 23 the stufling box chamber 24, the apertures 25 and the axial bore 26 and then through the joint 27 and the pipe 28 intola collecting tank (not shown on the drawing).

The gear is emptied by means of compressed air, when the primary parts are turning. Like the liquid, the compressed sir air is induced through pipe 18, enters the I working-chamber through the apertures22 and forces the water, which is impelled to" the periphery by reason of the turning movement, through the pipe 23, chamber 24 and pipe 28 into a collecting tank.

It may also be seen from indications in the drawing that the shaft 6 and wheel 7 are at the same time employed to drive a second gear 29 with driving-wheels 30, 30', which is arranged symmetrically to the liquid driving gear described above.

ig. 3 shows a gear, of which the secondary part is fitted up as a hollow shaft serving as a bearing for the drivin -shaft upon which the primary part is fixe The force of the motor (not shown in the drawing) is transmitted by gears31, 31' to the primary part 32, 32 fixed to the drivingshaft 1. The secondary part 33, 33 forms a hollow shaft and is provided with bearings 34 carrying the driving-shaft 1. The secondary part 33, 33, carries brackets 35, 35' provided with bearings 36 serving as outer hearings to the shaft. The secondary art 33, 33 is carried by the frame R, R. filling and emptying of the gear. is brought about in the same manner as in the example of execution according to Fig. 2. V In order to prevent any leakage, stuffing boxes 37 are provided which are supplied with chambers 38 taking up any leakage water, which through openings 39 can pass outside. The shaft 1 shows rings 10 slinging any leakage water, which should reacli them, outside through the openings 41 of the bracket.

The working-chambers, by means of which, at the same time the thrust is neutralized are provided, inorder to enable the gear be of the smallest possible diameter nplest possible construction and to to the fullest extent the space hethe driving-wheels. One of these w g-cha-rnbers in the example given in rawing consists of two blade-wheels, the primary part works as a pump and the secondary part as a turbine. he axialand radial clearances between the two gearshafts can be allowed variations within the such variations exercising any perceptible influence on the degree of efficiency obtained.

The method of employing the above described vehicle is thefollowing:

The starting of the motor of, say, an oildriven engine, takes place when the train is standing still, as in the case of a stationary motor. If the driving-gear is empty when the start is made, it must be filled as soon as the motor has reached a certain number of revolutions. The gear can be partially or wholly filled while the train is starting. After filling the driving-gear, the motor is supplied with its largest quantity of fuel Y and the train is set in motion, as soon as the starting moment has arrived. The maximum supply is retained until normal speed is reached. At intermediary stations the motor can be allowed to continue to run with full or partially full or empty gear while the train is at rest; it does not require to be started afresh on each occasion. This reduces the consumption of starting-air to a minimum.
