Application January 21, 1927, serial No. 162,534
133 Claims. (Cl. 214—16.1)
The invention forming the subject matter of
this application is a continuation in part of my
copending United States application, Serial Num

ent system of vehicle storage, I have arranged the
vehicle carrying ?oors and runways everywhere
horizontal and have provided locking mechanism
of the utmost simplicity, so that nothing short
of a complete wrecking of the structure can cause
a stored vehicle to fall out of its stall.
The main object of my invention is to provide
an automatic system of this type with means for
positively controlling the movements of a vehicle
during its transfer from one location to another
in the structure, and to avoid all tilting of vehi
cles into gravity actuated movement from one
location to another and against stop members

30 parts of the pusher mechanism illustrated in Fig
ing 28 of a driving motor‘23 ?xed centrally to a
ure 4.
In Figures 1 and 2 of the drawings, the system
is shown as including a framework constructed
to provide a plurality of horizontal groups of
stalls arranged vertically in tiers.
The ground ?oor is shown‘ in Figure 2 as com
prising an entrance wing I and an exit wing 2 ar
ranged on opposite sides of a room 3 which is di
vided by a key operated switch board 4 into a
customer’s part 5 and an attendant’s office 6;
Runways ‘I are formed in each wing and are
adapted to aline with similar runways 8 on turn
tables 9, which may be rotated to cause their run
ways 8 to aline either with the runways ‘I or with
45 the runways ll] of the trolley ll mounted to move
on the horizontal supporting rails l2 ?xed on the
vertical framework of the system to aline with
similar rails l3 on the elevator l4.
The structure as a whole is arranged so that the '
50 trolley may be lifted by the elevator to any de
sired tier, and may then be moved horizontally
cross strut 30 at the lower end of the trolley
framework. It will be obvious from the drawings
that energization of the motor 29 in one direction
or the other will cause rotation of the ?anged
trolley wheels 25 to drive the trolley in any de 35
sired direction on the rails l2 and I3.
In order to move a vehicle .in either direction
from the trolley, the latter is provided with
duplicate independently operated pushers, only
one of which is described in detail herein, al
though both are shown in Figure 5.
Each pusher lever 30’ (see Fig. 40) comprises
a pair of plates 3| spaced apart at one end by
a'roller 32 mounted to rotate on the pivot rod 33
secured to one .end of each of said plates. A
swivel 34 is pivoted to the rod 33 and has pivotal
ly connected thereto the vehicle retractor 34'
(Fig. 9) which, with other mechanism to be de
scribed later, serves to operate a combined vehicle
locking and releasing mechanism and to with 50
draw vehicle's from their stalls. A combined

spacer and cable grip 35 spaces and secures to
deliver or remove a vehicle to or from any desired
gether the plates 3| intermediate the ends there
of; and the'ends of these plates 3|, opposite the
stall in that tier. In order to effect this, each
.55 tier of stalls has a rail l2 secured to the vertical
framework in such positions that the runways III
of the trolley are always on the same horizontal
level as the runways I5 in each of the stalls l8.
Each stall has a pair of these runways spaced
apart to correspond to the spacing of the trolley
runways l0 and to the standard spacing of the
Wheels of such vehicles as would normally be
presented for storage by the system.
_
One of the most important units of this system
is the vehicle pusher mechanism, which is de
signed for use mainly in moving a vehicle from a
trolley into the stalls, to set locking mechanism in
each stall to hold a vehicle therein, to release this
locking mechanism and withdraw a vehicle previ

.vided with guide trunnions 36 adapted to slide
in cooperating guide grooves 31 which are formed
in a vertical bifurcated pusher guide-38 ?xed to
the cross bar 39 of the trolley framework.
At the start of the pusher movement, the 60
,pusher‘lever 30' is positioned so that its roller 32
lies below the bottom of the trolley runway 10, in
order to permit the passage'of a vehicle there
onto. To ‘provide for this, the runway I0’ is
broken to form a passageway 40 for the roller 65
32, and the two parts of said runway are ?xed
in alinement with each other‘by a suitable roller
receiving casing member 4|, shaped to receive the
roller 32 below the runway l0, and by such other

the said parts properly.

A combined chain and cable drive is provided

wherever found necessary or desirable in the

the top of the runway to and across the other end

turn, pivotallyvconnected to the cable 51 by a
‘tal and may even be slightly inclined to the hor
izontal so as to tend to move the vehicles against
the back walls of the stalls and away from the
pivot 62, the distance between these two pivots
being exactly equal to the radius of each of the
drive wheels 44 and 41. ‘This construction serves
to maintain the cable 51 approximately centered
between the upper and lower stretches of the
chain 46 during the operation of the pusher,
and thereby eliminates the undue stretching of
the cable 51 which would otherwise result from
direct, connection of_ the cable 51 to the chain 46
_and the consequent raising and lowering of the
cable 51 to the top and bottom of the sprocket

through suitable ‘apertures in the lug 92 and the
upturned end 96. A nut 99 is ?xed to the rod 98
and serves as one abutment for said spring 91;
40 and a second nut I88 is threaded on to the end
of the rod 98 where it projects outwardly through
of spring91 until the pin reaches the intersectionv
of the groove 12 with the cross groove 15. The
pressure of the strong spring 91 then moves the
pin 69, and the retractor with it, across the cross 20
groove ‘I5 into the groove 13. The retractor roller
is then in front of the right hand rear wheel of the
vehicle and engages said wheel to withdraw the
vehicle from the stall as the pusher moves back
ward to the trolley. When the pusher nears its
rest position, the pin 69 enters the cross groove
14, passes the frog 16, enters the groove 18 once
more, and thereby withdraws the retractor roller
from its wheel engaging position over the runway
I8. The frog 16, of course, closes the cross groove 30
14 and prevents accidental movement of the pin
69 directly from the groove ‘I8 into the groove 14.
The retractor 34 is also used, as it moves into
and out of a stall, to operate mechanism for
locking and holding a vehicle therein. On the
left hand runway of the stall, a plate I82 is
hinged and is provided on one of its lateral edges
with a pin I83 adapted to slide in a cam groove
justing the rod 98 so as to space the nut 99 from
I84 formed in the wide segmental edge of a
locking quadrant I85 pivotally mounted on the 40
stall ‘?oor. An arm I86 projects radially from
the. quadrant I85 and is of such length that it
can be tripped by a pin I81, projecting laterally
the lug 92 at such a distance that the plate 19 is
downward from amoi’fset I88 formed on the re
the upturned end 96 to serve as a means for ad
.45 not subjected to the action of the strong spring
91 until the edge I8I of the shunt plate 19 lies
across and obstructs the groove 12.
If the pusher were operated without a vehicle
being either on the trolley or in the stall, the

When the trolley next comes to the stall to
remove a vehicle therefrom, the pusher moves
into the stall and pushes the retractor 34' ahead
of it, with the retractor pin 69 riding in the
grooves 18 and 12.- As the pusher moves into
the stall, pin 69 engages the edge I8I of the shunt 15
plate and moves it laterally against the pressure

in the alined guide'grooves 18 and 12 without
moving the retractor laterally across the runways
ID or I5.
'
When the trolley arrives at a stall with a vehicle
55 to be stored therein, the pusher roller alone en
gages the rear end of the right rear wheel of
the vehicle to push the vehicle into the stall;
and the retractor pin 69, riding in the alined
grooves 18 and 12, holds the retractor out of
60 engagement with the front of said right rear
wheel. As the vehicle moves into the stall, its
right front wheel passes over and momentarily
depresses the plate 85 to cause the linkage mech
anism to move the shunt plate 19 over into the
65 groove obstructing position shown by dotted lines.
tractor 34', only when the pin 69 reciprocates in 45
the alined grooves 18 and 12.
.
The arm I86 is normally positionedv in the
path- of the pin I81 by the bumper springs“!!!
and H8, each of which has one of its ends fixed
relatively to the floor of the stall. It will be 50
obvious from the drawings that as the quadrant
is moved from one position to another between
the springs I89 and H8, the cam groove I 85 will
cause movement of the pin I83 from the hori
zontal part III of said cam groove to the other 55
horizontal part H2, and vice versa. It will also
be apparent that when the pin I83 is in either
horizontal portion of the cam groove the plate
I82 is locked in position and can be moved, only
by moving the quadrant I85.
As the retractor 34' moves, with its pin 69 in
the grooves 18 and 12, into a stall, the trip pin
I81 trips the arm I86, if it be in locking position,
and lowers the locking plate I82; and, as the
retractor moves out of the stall, with its guide 65
pin 69 still in grooves 12 and 18, its trip pin I81
After the front wheel has passed over this plate‘
85, the several springs restore the plates 19 and 85 - again trips said arm I86 and raises the plate

t
It will be noted that the guide members 31
are not located centrally of the trolley. The
reason- for this will be obvious from the fact that
the pusher must actually enter into the stall in
order to position a vehicle so that its rear'end
may not project outside the stall. This will also
' explain the reason for offsetting the roller end
of. the pusher le.er, since the lever must clear
the ?oor of the stall as it projects thereinto.
The curvature of the guide members can be
20 readily determined by plotting the lever in differ
ent positions with its roller pivot lying in differ
ent positions in the line :cl—x, which is located
sufficiently, above the runways to ensure proper
clearance for the pusher roller‘ and effective
25 driving contact with‘ a vehicle wheel. The meth
od of plotting these curves is set out in'detail
in' my copending UnitedStates application Serial
Number 24,305 ?led April 18, 1925, and need not
be further described here.

At its other end, the .carrier I22 has an up '10

block I30 suitably ?xed to the top thereof.‘ A
pair of lugs I3I' project laterally from the said .
arm, and are .provided- with'apertures I32 to
serve as guides for a pair of guide rods I33 con 15

pression springs I35 wound around said rods I33

arm I29. The contact block I34 is provided with
a guide plate I36 whichis slidably mounted in 20
a slot I31 formed in the arm I29 and inan oifset

A magnet I 40 is supported on the under side .
of the top I4I of the casing I20 to control ,an
armature I42 mounted on an insulating block

desirable in the system. In Figure 2, for exam-'
ple, a pusher. unit is indicated as installed in the
of the casing I20. The arm I44 is curved ‘up
wardly to form a stop I41 which bears normally
ground ?oor entrance wing to move a vehicle
on to a turntable equipped with duplicate pusher
units similar to those already described as mount
ed on the trolley. The retractor and locking

against a roller I48 mounted on the arm I23 im
therefrom and over the insulating block I30 to

there is nothing more required than the pushing
40 of a vehicle from one location in the system to
an adjacent location.
‘
There is nothing particularly novel in the me
chanical details of the turntable itself, the nov
elty residing mainly in the combination of the
pusher mechanisms and electrical controlling de-'
vices with the turntable to cause it to operate
’ automatically in cooperation with other elements
of ‘the system. The turntable structure itself
comprises a ?xed'annular rail II3 adapted to
support and guide the rollers II4 journaled in
the bearings II5 on the framework II6, to which
is secured‘ the worm gear ring II1.in mesh with
the worm. II 3 which is adapted 'to be rotated by
- the motor H3 in either direction to cause rota-'
' ; tion of the turntablé in to positions necessary to
effect alinement of the turntable runways with
the runways on the trolley or in the wings of the
system. The automatic control ‘echanisms for
‘the turntable} will be described in detail herein‘
(30
after.
'
'
‘
The system as a whole is automatically'oper
ated by electric switch mechanism, arranged on
the control panel]. Each stall is provided with
a. series of contacts electrically connected bysuiti
able wiring. through‘its own particular relay, -to
its own particular key-controlled switch on the
panel 4, and the vehicle carrying‘ trolley is pro
vided with a corresponding series of circuit mak
ers and breakers to cooperate with said contacts
and with motors carried by the trolley to stop
the trolley at the stall, operate the vehicle pusher,
and start the trolley back to the elevator or to
the main entrance, as conditions require.
.
‘Each circuit maker’ and breaker, hereinafter
referred to as a contactor, comprises an insulated
ment of_ the arm I 44 when the magnet is~deen
ergized.

To cooperate with the contactor just described,‘
a contact I50 is secured in an arcuate insulating
block I5I mounted in the base I52 which is
adapted'to be suitably secured to any part of the
system wherever found necessary or desirable to 45
operate a contactor of the type described. For
example, it may be mounted on the structure
framework adjacent a stall to make contact with
block I34 of a contactor carried by the trolley.
Each contact I50 is connected by its wire I53 to 50
its particular key controlled ‘switch on the control
panel 4.

These contactors are designed to control motor
operating latch switches of a type, peculiar to
this system. For the purpose of illustration, one 55
of these switches is " shown in Figure 13 as con
nected up to two contactors to be controlled
thereby. The switch comprises an arm I54 piv-'
oted at one of its ends and carrying motor con
trol contacts I55 and I56 at its free end. The
60
arm\I54 is normally pressed into inoperative posi
tion against a stop I61 by a compression spring ‘
I53, and may be drawn into circuit closing opera
tive position by means of an electromagnet I59.
An arm. I60 projects laterally from the army I54 65
and is provided with a projecting-shoulder I6I
- adapted to be engaged by a cooperating shoulder
I62 at one end of a latch I63 which is pivoted
at its other end and is provided with an arma-
ture I64 adapted to be attracted by the electro 70
magnet I65. As shown in Figure 13, the motor
switch arm I54 is latched in circuit closing posi
tion.

The magnet I40 has its wiring connected at

I55, and has its other end connected by the wire
I61 directly to a spring contact plate I68 ?xed
on‘the switch arm I54 and adapted to move with

wire I69. ?xed inside the casing I20 are con
the stall and the contact block I34 has again been
projected to permit the arm I44 to fall with its
offset at rest on the insulated block I30. In
other words, when contact is made, the magnet
I40 is energized ?rst, then magnets I40 and I65
tacts I15 and iii in such position that they
make'contact with the offset I49 of the arm
I56 only when said‘ arm- is pulled up with its
armature against the magnet I00. A wire I12

10 connects contact I1I to the plate I38; a wire
to that just described and is effected by a struc
turally similar connector G. in this case, how
I33 connects contact I10 to one end of the elec
tromagnet It5; and a wire I'M‘connects the other
end of the magnet I65 to the wire I61, which, as
previously described, leads through the spring
15 contact I68 and Wire I69 to ground.v
As so far described, the contactor I20 may be
considered as controlling the circuit breaking
magnet I65 to throw. the switch arm I54 out of
operation and corresponds to the contactor
20 designated by the reference character F in the
wiring diagram of Figure '25. A. second con
tactor, the position of which is merely illustrated
diagrammatically in Figure 13, is used to operate
the circuit closing magnet I59, and corresponds
25 to that designated by the reference character G
in Figure 25. The operation of these contactors
ergized until their common ground connection is
broken.
The closing operation of switch I54 is similar
ever, the wire lil5, corresponding to the wire IE1,
is connected directly to the spring contact plate
I'I8 which contacts with the wire I19 when the
latch 363 is in raised position, the wire I19 being
connected in turn to the ground wire I69. The
wire I16, corresponding to the wire I13, is con
nected to the same spring contact plate I18
through the magnet I59 and wires I11 and I15.
When the circuit is closed through the contact 20
plate I34 of the contactor G, current flows first
through the wire I55 to the contact plate I18,
and thence through wires I19 and I69 to ground,
thereby energizing the magnet I40 of contactor
G to cause it to snap up the arm I44 against the
contacts I10 and HI of contactor G. Then, with
is somewhat as follows:'—-Assuming that the
the arm I44 raised as described, current ?ows si
switch I54 is in circuit closing position, as shown
in Figure 13, and is held in this position by the
latch I63, with the trolley moving toward a stall
multaneously through magnet I40 of contactor G
and the circuit closing magnet I59, through wires
I15 and I16, spring contact plate I18, wire I19
to move a vehicle thereinto or withdraw one
therefrom: then, when the trolley arrives at the
stall, the. contact I50 forces the contact block
I34 inwardly against the pressure of the springs
35 I35 and closes the circuit from the wire I53
through the arm I29, roller I48, and wire I66,
magnet I40, wire I61, spring contact plate I68,
and wire I69 to ground, and holds these magnets
energized until the magnet I59 draws the switch
arm away from its stop I51 sufficiently to permit
the latch I63 to fall into locking engagement with
the arm I60'and separate the contact plate I18 35
from the grounded wire I19.
It will‘be apparent from the foregoing descrip
and wire I69 to ground. This energizes the mag- _ tion that when once either the opening or closing
net I40 and causes it to snap up the arm I44 circuit operations have been performed by either a
of the contactors, neither operation can be again 40
40 to make the offsetthereof contact with the con
tacts I10 and MI. The springs I35 immedi
ately force the arm I29 under the arm I44, and
current then ?ows from the wire I53 through‘
the wire I12, contact "I, and offset I49, where
46 it splits at the contact I10 to ?ow through the
arm I44, wire I66, magnet I40, wire 'I61, and
spring contact plate I68 to the ground wire
I69, and also through contact I10, wire I13, cir
ciiit opening magnet I85, and the wire I14 to the
50 wire I61, contact plate I68 and ground wire I69.
This energizes both magnets I40 and I65 si
multaneously and holds them so energized until
the magnet I65 shall have attracted the latch I63
from engagement with the arm I60, thereby per
55 mitting the spring I58 to force the switch arm
I54 back against the stop I51 into open circuit
position.
As soon as the arm I54 is released the
contact plate I68 separates from the ground wire
I69, and the circuits through the magnets I40
60 and I65 are at once broken.
The contactor arm
I44 immediately falls away from the contacts
I10 and HI and rests on the insulated block I30
with the o?set I49 out of contact with the con
tacts I10 and I", the distance between the top
65 of the block I30 and the contacts I10 and HI
being greater than the distance between the bot
‘ tom of arm I44 and the top of o?set I49 in order
to provide a gap between‘ said top and contacts
when the arm I44 rests on top of the insulated
performed while the operated contactor is in con
tact with the contact plate which caused such op
erations.
The return line in each stall is normally broken,
and a magnetic switch MS is located in each stall 45

wiring is turned to energizing position, and to
cut in the line where it leads to other points and

has its other end connected by a wire I90 to the

switch will be apparent from the illustration
thereof in Figure 25, and will be described in de
tail when the operation of the control mechanism
is taken up later for description.‘
