vEHrcULAE. EIEE ESCAPE.
App1icationfi1ed June 29,
T 0 all whom it may concern Be it known that I, CONRAD MAYER,
Ulm a.
ject of Germany, residing at a sub- Donau, Germany, have invented certain new and useful Improvements in Veh icular F re Escapes, of which the following 18 a spec fication.
In vehicular fire escapes in which the car frame or chassis is supported on springs, the springs, or the spring suspension of the car frame, should be inoperative when the fire escape proper is in the position of use, for
which purpose the axle is locked to the car frame for instance by means of a hook,
The object of the invention is to render p the car springs operative or lnoperative automatically by means of the elements which actuate the ladder or escape.
A construction accordlng to the invention is diagrammatically illustrated in the accompanying drawing. Figure 1 shows the locking device in the inoperative position with the escape in the lowered or travelling position,
Figure 2 shows the locking and device in the operative position at the moment when the raising of the escape begins.
Figures 3 and 4. are detail views.
A hook 1 which renders the springs inoperative is rotatably mounted on a pin 2 on the car frame 19 and when the escape is being raised is positively moved by a tappet or driver 4 provided on the raising frame 3 of the escape.
This tappet or driver is in the form of a guide provided with a cam slot 4 with which engages on a lever 6 rotatable about turning frame 7 a pin 5 mounted a pivot 8 on the When the raising of the escape begins, the
and bellcrank levers 13 and 14 actuates the hook 1 in such a manner that the latter is thereby brought into engagement with the car axle 15 or with a separate holder provided on the said car axle. The springs 20 of the vehicle will be thereby rendered inoperative.

movement will take place, the pin 5 slidingalong the upper track of the tappet 4 (Figd. ure 3).
GERMANY, Assreno To cgn. MAGrEUs; AKTIEMGE- n. DONAU, GE ANY, A conronn'rron or GERMANY.
the rod 11-which is guided in the car frame is formed with a T-sha ed slide block 18 (Figure 4.). As soon ast eescape is brought on the turning rim 16 into the travelling osition, the head 17 will be coupled to the block 18, and a positive connection will then be established between the tappet 4. and the hook 1, whereas during the turning of the frame 7 on the turning rim 16, this connection will be severed.
The tappet or driver 4 could be arranged at any desired point of the frame participating in the raising movement, or at any desired point of the escape.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be'performed, I declare that what I claim is 1. In a vehicular fire escape having a wheeled chassis and a ladder mounted thereon, means for rendering the car suspension in operative when the ladder is to be used, and operative when the ladder is lowered into the traveling position, said means comprising a lockin device for rigidly connecting the chassis and axle of the vehicle, link mechanism for actuating said device, and a member connected with said ladder for engaging said mechanism to cause said locking device to be thrown automatically to locked position during the initial raising movement of said ladder.
2. In a vehicular fire escape having a wheeled chassis and a ladder mounted therenism for actuatingsaid device, andamember With said ladder and adapted to engagesaid mechanism, said member being provided With cam surfaces for causing said mechanism to actuate said locking device automatically to locked position during the initial raising movement of said ladder and to unlocked position during the final lowering movement thereof.
3. In a vehicular fire escape having a Wheeled chassis, a turningframe rotatably mounted on said chassis, a ladder carried by said turning frame, a locking device rigidly connecting the chassis and the axle of the vehicle, link mechanism for actuating said device, a member connected With said ladder for engaging said mechanism to cause said locking device to be actuated, said mechanism including a detachable coupling constructed and arranged to be disconnected or connected, respectively, automatically by the turning of said turning frame out of, or
into, the traveling position of said frame.
In testimony whereof I affixmy signature.
CONRAD MAYER.
