in Germany February 21, 1933 29 Claims,

The subject of the present invention is an apparatus which enables endless track vehicles to travel upon railway tracks. This apparatus in accordance with the invention is in the form of a frame which embraces the endless-track vehicle and is provided with railway track Wheels. The frame provided. with wheels thus constitutes a carriage in which the endless-track vehicle is accommodated in such a manner that its endless tracks lie upon the rails of the railway track, whereby the endless-track vehicle can travel upon the railway rails without the possibility of sliding off them.

According to the invention the apparatus which enables the endless-track vehicle to travel upon the railway track is so constructed that the endless track vehicle itself can travel on to or into it without it being necessary for the driver or the crew to alight.

Since railway rails are smooth, it is not necessary for the enmess tracks to bear hard thereon as is the case on the contrary when travelling for instance across country or upon the road. Owing to this reason a portion of the weight of the endless track vehicle may be transferred to the wheels of the guiding apparatus, that is to say to the wheels of the carriage in which the endlesstrack vehicle is accommodated. When the tracks of the endless-track vehicle are partly relieved of load they have a higher efficiency and thetravel of the endless-track vehicle upon the railway rails then necessitates a much smaller output of the motor, the power in excess of which may in such cases be utilized for increasing the speed of travel.

An endless-track vehicle together with the guiding apparatus, which in accordance with the invention is provided with means for transferring a portion of the weight of the endless-track vehicle to the railway track wheels of the guiding apparatus, actually travels at a much higher speed than would be possible upon the road.

The subject of the invention is illustrated in a number of constructional forms in the accompanying diagrammatic drawings in which, as well as in the following description still further features of the invention are set forth.

Figure l is a side elevation of a guiding apparatus in the form of a frame in which the endless-track vehicle is seated,

Figure 2 is a top plan view,

Figure 3 is a side elevation of a modified constructional form of the apparatus,

Figure 4 is a top plan view of the apparatus according to Figure 3,

Figure 5 is a side elevation of a further constructional form of the apparatus with means provided at both its ends which enable the endlesstrack vehicle to travel on to the apparatus and to travel down from it. I 7

Referring to the drawings, the apparatus shown in Figures I and 2 which enables the endlesstrack vehicle to travel upon the railway tracks has the form of a carriage and comprises the frame 1 and two axles 2, each of which is provided with two wheels 3. At one end of the frame 1 the shaft 5 is mounted in the bearing pedestals e, on which shaft the platforms 6 and '7 are pivotally mounted which serve for enabling the endless-track vehicle to travel onto and travel down from the carriage, said platforms being provided with brake blocks 3. The endlesstrack vehicle travels upon the platform 6 over the wheels 3 and downwardly upon the platform 7 into the frame '1, the brake blocks 8 being applied to the wheels 3, thereby preventing the latter from rolling upon the rails 9. The platforms 6 and 7 are provided with guide flanges 10 and the frame 1 with sheet metal guide Walls which guide the endless-track vehicle in such a manner that the tracks 12 thereof are brought 0 into position upon the railway rails. A hand lever 13 is rotatably mounted upon the pivot pin 14 on the frame 1, said hand lever being connected to a lever 16 by means of a rod 15; The lever 16 opens the claw-shaped grippers 17 which 5 serve for seizing the hook 18 or the like provided on the housing. The lever 13 is also connected by means of a tension member 19 to a support member 20 which by means of a spring 21 is also always held in a substantially horizontal position. If the gripper 17 is open, then the free end of the abutment member 20 which is pulled by the lever 13 and the tension member 19 is forced against the ground and renders movement of the carriage upon the rails impossible. The lever 13 is connected with the cranked lever 23 by means of the tension member 22 which is connected by means of the tension rod 24 with the lever 25. The levers 23 and. 25 serve for raising the platforms 6 and 7. The lever 13 is con- 0 nected to the lever 23 in such a manner that the platforms 6 and 7 are lowered when the gripper 17 is open.

The lever 13 is so arranged upon the carriage that it is situated opposite to an opening inthe housing 1 of the endless-track vehicle. If the endless-track vehicle is to be driven into the frame 1 of the carriage, then the lever, 13 is situated in the position shown in the drawings; the

platforms are then lowered, the brake blocks 8 11,0

hold the wheels 3 stationary, the abutment 20 is forced into the ground and the gripper 1'7 is open. When the endless-track vehicle hastravelled into the frame 1, then the lever 13 is rocked to the left (Fig. 1) by hand from the inside of Y the endless-track vehicle through the opening in the armour casing of the endless-track vehicle without the driver having to step out, whereby the endless-track vehicle is simultaneously secured to the frame by the gripper l? engaging round the hook 18, the abutment 2c is raised by the spring 21 and the platforms 6 and '7 ar raised.

On the springs 26 of the frame 1 is mounted a rotatable roller 27 which serves for elastically supporting the endless-track vehicle after the latter has entered the frame 1, a part of the weight of the endless-track vehicle being automatically transferred to the wheels 3 the endless-track vehicle resting by endless tracks 12 upon the railway rails 53 with a force equal only to the remaining part of its weight.

For regulating the amount of the portion of the weight of the endless-track vehicle which is to be transferred to the wheels 3 or for completely raising the endless-track vehicle in order that the tracks 12 do not bear against the rails 9 at all, the following apparatus is provided. On each side of the frame 1 are rotatably mounted two cranked levers 23 which are provided with swivel abutments 29 whicl'i are capable of being turned through 99 in the horizontal plane. To the upper ends of the levers 28 are articulated two rods 30 each of which consists of two parts which are connected together by means of a nut 31 provided with right and left hand threads, this nut 31 being accessible from the interior of the endless-track vehicle through its side opening. By turning the nut 31 the abutments 29 are raised and lowered and raise and lower the endlesstrack vehicle to the desired height.

This apparatus has the advantage that with the aid of the means for securing and adjusting the endless-track vehicle into a suitable position it is possible to manceuvre the vehicle from the inside of the endless-track vehicle. All the functions attending the travel of the endlesstrack vehicle into the frame and out of it can be carried out for instance in the tank without the crew having to alight therefrom.

In the constructional form according to Figures 3 and l, the inclined platforms are ir movably secured and are provided with extensions in the form of a smaller platform 3 suspended on hinges and provided with openings 33. The openings 83 are provided for the reception of the rails 9.when the free ends of the platforms 32 are forced to the ground by the tracks of the endless-track vehicle during the travel. of the latter on to the carriage. Each platform 32 is provided with a spring E l which supports it in a horizontal position.

A trian ular frame 36 is connected to the frame 1 by means of hinges 35, a hydraulic jack 3? or other raising device of a suitabl kindbeing situated under the of the frame. A lever 38 is connected to the jack 3'? which serves for pumping the liquid serving for raising the frame 36- and a second lever 39 is connected to the jack for opening the valve in the jack serving for allowing the liquid to pass out of it. The ends of the levers 38 and 39 are situated under the opening in the bottom of the tank,'whereby these levers can be manipulated from'the inside of the tank without the crew having to step out of the tank.

In Figure 5 an apparatus is shown in the form of a carriage which is provided at both its ends with platforms 6, 40 and '7 serving for enabling the tank to travel into and out of the frame 1. By means of this apparatus the tank can travel in either direction along the rails, in that the tank may be caused to travel into the frame from either end. In order to enable the direction of travel to be changed, the tank must travel out of the frame 1 on to the platforms '7, ll), 6, travel round the carriage and enter the frame at the other end upon the platforms 6, 40, '7.
