spider 5. During this ?rst movement and ow
placement of the roof is a geometrical transla

tion, but, in practice, and owing to the shape and
ing to the arrangement of the toothed segment
24, the pinion 23 is not rotatively driven and, con
sequently, the movable portion I of the car body ' arrangement of the spider, it is necessary that
the roof should slightly rock backwards (the word

A pivot pin 48 is secured on the lever 4I at an
portion I to be withdrawn within the spider 5.

ment 24 again comes in engagement with the pin is loosely mounted a toothed pinion 41 rigid
pinion 28 and a rotation of this segment having with a sprocket wheel 48. The toothed pinion
41 meshes with a ?xed toothed segment 49. A
sprocket wheel 58, rigidly secured on the end of
the shaft 45, rotatively drives, through the me 20
dium of a chain 5I, the sprocket wheel 48 and,
consequently, the pinion 41. On the shaft 45 is
rigidly secured'a worm wheel 52 meshing with a
amplitude CD=AB causes the spider to be closed.
The links 8 and I I move to the position indicated
20 in dotted lines in Fig. 2 of the drawings, if it
is assumed ‘that they were at the beginning in the
position indicated in full lines. A rotation of

causes a similar operation: opening of the spider,

In the form of construction of the control de
vice illustrated in Figs. 5, 6 and '1, the principle
of the device remains the same, alone the ar
‘so
rangement and the mode of actuation of the
various members are different. The shaft I2
controlling the movement of the cover 8 of the
spider 5 is placed near the end of this cover, or,
in other words, at the upper part of the spider

frame for instance.
'
‘
A shock absorbing device is mounted between
apoint 58 situated on one of the levers and a
?xed point 51 of the car body or other ?xed part.
This shock absorbing device is constituted by a 30
cylinder 58 pivoted at 58 on the‘ lever 4|,‘and in
which moves a piston 58 the rod 80 of which is
pivoted at a ?xed point 51. A spring 8| is inter
posed between the piston 58 and the rear head
82 of the cylinder adjacent to the pivot point 51. 35
The arrangement of the links 8 and II re
mains the same as previously, with the exception It will be seen that, in this manner, when the
that the length of the links is greater for an roof is: either in position on the car body as shown
equal lift of the cover 8. The sprocket wheel' in full lines in Fig. 2, or within the spider as
28 is loosed on the shaft 28a carrying the pinion shown in dot and dash lines in this ?gure, the
22 in engagement with the chain 28 actuating ‘ spring 8| is compressed and, consequently, tends 40
the movable portion I. Each of the shafts I2 to promote the displacement of said roof at the
and 23a carry threepinions ,(85, 88, and .81 for
the shafts I2, 88, 88, and 48 for the shaft 28a,
arranged opposite each other). The pinions 85,
45 81, 88, and 40 are loosely mounted on their re
spective shafts, but the pinion 88 is rendered
rigid with the sprocket-wheel 28; the pinions 88
and 89 are secured on the shafts I2 and 23a, re
spectively. On both these series of pinions is
50 mounted a chain 4 I, the middle stretch or vlength
of which, in engagement with the pinions 88 and
88, is gapped so vthat it is in engagement at any
moment with but one of these pinions (Fig. '7).
When the pinion 38 is driven through the ‘me
55 dium of the sprocket wheel 28 in the direction‘ of
- the arrow .1, it drives the chain H which causes
the pinion 88 to rotate through a sui?cient ampli
“ tude for causing the cover 8 of the spider to lift;
the chain 4I then comes in engagement with
‘the pinion 88 which it actuates for determining
the displacement of the movable portion of ‘the
, car body, then it again actuates the pinion 88 for
closing the spider. .An operation in the reverse
direction produces a similar result, viz: opening
65 of the spider, replacement of the movable portion
on to the vehicle body, closing of the spider.
In the form of construction illustrated in Figs.
8 and 8, alone the (means used for the displace
ment of the movable portion I and the parts of
the mechanism located on one side of the car
beginning'of the movement.
The operation of the device according to the in‘
vention is as follows: the motor 54 can rotate
in both directions and a suitable control device is 45
provided for controlling this direction of rota
tion according to the position of the movable
roof I. Assuming the roof is'in position on the
car body, the motor is started for driving the
shaft 45 in the direction of the arrow 1, the 50
sprocket wheel 48 rotates in the same direction
and it will be seen that the lever 4I rotates in
a clockwise direction, actuating the roof I in
order to insert it in the spider.
_ By causing the motor 54 to rotate in the reverse 554
direction, the movable roof is restored on to the
car body. It is obvious that the device for auto
matically reversing the direction of displace
ment at the extreme positions can be of any type
githout departing from the ~scope of the inven
60
on.
In the form of construction illustrated in Figs.
10 and 11, the displacement of the roof is also
obtained by means of levers 48 and H the pivot
points 42, 44 and .48, 45 of which constitute the 65
apices of a. four-bar motion. But, in this form
of construction, one of the groups of levers com
prises a single lever H which is arranged‘ in the
transverse axis of‘ the movable part I and the
operating means act on this single lever. These 70
operating means are constituted by a screw
