ARRANGEMENT FOR CHANGING THE MACHINERY OF HIGH-SPEED SUSPENSION.
Application filed January 24, 1925, Serial No. 4,576, and in Germany November 12, 1924.
This invention relates to an arrangement for the rapid replacement of machinery, particularly with regard to high speed suspensionv cars, that are driven by means of an air screw. `Such an arrangement can be used for example for the rapid replacement of a broken down motor, or for fitting a different type of motor, if the car is to travel at a different speed. In the case of a normal railway, where a number of separate cars are coupled together, the separation ofthe machinery orpower means, that is the locomotive, is very simple, and moreover the coupling is arranged without any considerations of airfresistance, but with the high speed suspension car an entirely different problem is presented. Owing to'the much higher speed the machinery of a high speed suspension car takes up about 30% oiI the whole space' and its weight is about 50% of the whole weight. hIoreover the vbody of the car containing the machinery Vmust be of streamline :form and 'must act aerodynamically as a single body.
In the accompanying drawings are shown severa'l arrangements for separating the machinery from thecar. In several of the arrangements provision has been made, at the same time for insulating the vibrations and noise of the machinery from the passenger compartment. i
Figs. `1 and 2' show in longitudinal and transverse section one form of car. d Figs. 3, 4 and 'show another arrangement being respectively, a vertical longitudinal section, a horizontal longitudinal section and a vertical crossssection.
Fig. 8 sho-ws in transverse section means for preventing shock.
Figsp9f12 show other modified tormsA of connecting the sections of the car.
Figs. 1.3-15 show means `for closing the gap between the sections.
' InV Figs. 1 and 2er the drawings is shown an' arrangement in vvertical and cross sections, whereby the machinery canV be re'- moved` and replaced from below.
yThe engine 1, which drives thepropellershaft 2 through the coupling 5 is supported gether.
onthe lugs 7 on the brackets 3, which are iiXed tothe main bed t of the car body. Below the engine there is a suitable removable floor-section 6, which makes possible the removal of the motor, for which purpose the engine boltsvbetween the lugs 7 and the brackets 3 are removed. In the same way the other connections of the motor, for instance, the coupling 5 and the petrol-cooling water and oil pipes are disconnected, and then the motor maybe moved lengthwise of the brackets 3 and lowered through the opening'provided by the removal of the iioor i section 6. Similarly'a fresh engine can be put in from below. The Hoor-section 6 serves for closing the lower opening and is made in vstreamline-form. Y
. Another arrangement is shown in Figs.
3, 1 and 5, in vertical-longitudinal section,
horiZonta'l-longitudinal section and vertical cross-section. In this modification the m0- tor 1 is carried on a U-shaped bed 8, which is combined inone unit with the bottom plate, so that when the motor is removed the bed and bottom plate come away to- -The unbolting and disconnection of flanges and other parts is objectionable, and can be avoided by the arrangements shown Vin Figs. 6 and 7. The machinery together with the propeller drive isl carried on a single bed 9, which both underneath and at the rear is madein streamline form, and fitsinto a spe# cial opening of the car body. For changing the machinery in this arrangement fewer disconnections need to be made, in fact, possibly none except the removal of the holding down bolts, which hold ther achineryy into the body of the car. s
In order to insulate the car from shocks and vibrationsof the motor unit 1, the latter is supported on a frame shown in Fig. 84, supported by means of the springs 10, which rest on the brackets 11, `while lateral vibrations ar-e taken up by the springs 12 and 13.
Inv the further arrangements shown in Figs.v 9-15 the entire motor compartment or the motor 'alone is arranged as a separate part of the car, whichy may be carried on its own running gear. Naturally it ismade to conform with the streamline form of the d Whole car. For replacement the car-section,
containing the machinery is separated from i the mainbody of the car, and can, t'or cxample, move along the rail on its own runningwgear, or be removedby means of a crane. l
In the arrangement shown in Fig. 9, the section 15, containing the machinery, and the section for passengers or freight 14 runs on one or morebogies 16e-17 and each part is supported on the springs 1819.V Both parts, in order to ltransier the-longitudinal forces ina vibrationless manner, arey connected together by means ot the sprmOs 20 of the springs `26.vertica shocks are taken up, 4While the spring 27 acts as a coupling and for taking up horizontal shocks.
In the arrangement shown in Fig. 12 two machine-sections 15 are coupled with the passenger ortreight section 14. Y Instead of sup porting the sections 15 on running gears these can be fitted to the section 14. `In this case the connections between the two sections must be able to withstand bending. The arrangements of the Figs. 9412 naturally can be combined with those oit Figs. 18 and instead of the spring other elastic means, such as rubber, air-buffers etc. can be used. l 4
The space 28, resulting from the separation of the machine room, can be closed for aerodynamic, acoustic or atmospheric reasons, for example as shown in Figs. 13-15. The rubber collar 29 is fastened to one sect-ion, Aand is slidably litted on the other but securely held `by springs so, that it does not lift if a longitudinal movement takes place, as shown in the longitudinal section Fig. 14. The formation ot 'folds or cor'rugations in the collar during circumferential stress is prevented for exampleby means oi longitudinal inserts of very flexible Wire or the like. Another manner of securing the sections is shown in Fig. 15. The collarO is contracted in V-orm and the `form can be maintained' by the spring 31. y The resulting space because of its limited Width has no great influence on the air-resistance. `The resulting closed in termediate space serves for sound insulaf tion.`
