Re: Samples Submitted for Approval
Mobile Shelving
of your office delivered several samples to
this office for approval. The samples delivered are as follows:
a. One spring-loaded, key operated over-ride switch.
One magnetic-contact safety switch to be operated
by a tensioned cable,
c. One magnetic contact safety switch manually operated.,
d. One sample section of end panel, with mounted
selector switch for directional control, with
plastic corner moulding and edge moulding, and
with mounted moulded plastic and sections of aisle
safety control.
One box of floor tile samples for selection of tile
color and base moulding.
We have examined the samples and find the improvement in
workmanship and quality of materials to be heartening. The items we
now have are finished products rather than the original makeshift
experiments. Our questions and comments on the items submitted
are listed belowt

Rot Samples submitted - 5 April 1971
a. The spring-loaded override switch will be placed
within 1/4 inch of the steel shelving end panel and
it is felt that some sort of insulation is needed to
prevent short circuiting from the back of the switch
to the metal cabinet. Perhaps a moulded plastic cover
could be installed over the switchbody, with drilled
holes for insertion of control wiring. All switchkeys
should be alike rather than all different an w M one
set of master keys.
b. The hinged magnetic safety device on the chassis
(secondary safety device) appears to be a great improve-
ment over the model appearing on the mockup. Our
questions on this concern the method of applying coreect
tension to the cable. If possible would like a complete
switch mounted on a 61-0" long wooden frame with at least
one of the mid-span supports. The users are still in
doubt as to the capability of adjusting all cables to
same tension. They would like to see a unit set up
under operational tension and a short model would be
sufficient to demonstrate this.
Another question is in regard to the metal housing over
the switch. This housing will apparently protrude into
the aisle space and will be subject to damage by moving
ladders. Also this additional projection may prevent
the sections from closing tightly together, thus reducing
aisle space.
The cable attachment as shown on the drawings indicates
a loop in the cable and a tiller rope clamp. This
appears to be a possible future problem in maintaining
tension in the cable. We suggest the turnbuckle end
loop"be of sufficient width to allow drilling and
insertion of the dable and use of a Stimpson A1692 eyelet
soldered to end of cable. Any take up then made in
the turnbuckle would provide positive pressure changes.
The above comments are not meant as rejection of submittals
but rather as suggestions for possible improvements. We may be
able to eliminate some future problems by making minor changes in
the design prior to installation.
Sincerely yours,
