Description
This invention relates to devices for registering a watchman's time
at a watch station, and has particular reference to a key device
for registry with a watchman's clock to establish the time at which
a watchman is at a particular watch station.
In industrial, mercantile, and other establishments, it is
necessary to safeguard people, premises, and property, that a
watchman proceed on rounds of inspection and presence, at intervals
and degrees of detail established according to the requirements of
particular situations. Some situations may be suitably covered by a
few day or night trips by the watchman, well spaced in time and at
regular intervals. Other situations may require inspections at
short intervals or irregular intervals, or both.
In the course of such inspection rounds, it has been found
necessary to establish a time record in which the watchman checks
in at each of a series of watch stations. Such a record protects
the watchman as well as his employer for insurance purposes or to
establish presence in relation to time of events such as fire,
burglary, or other happenings of note in the matter of establishing
time of occurrence.
Such time record is established by using a watchman's clock, which
he carries with him, and keys for time registry of the clock, with
each key permanently located at a significant station, so that such
stations are suitably spaced along the watchman's route. The clock
is provided with suitable recording means, and each key applies its
own individual identification to such recording means, so that time
and watch-station identification are brought together to
permanently record when the watchman was at each of the watch
stations.
In the past, such watch stations have comprised a metal watch box,
with a door which is opened to reach a watchclock key located
therein on a chain which has one end secured within the box with a
key secured to the other end of the chain.
These stations are rather remarkably disadvantageous and involved
for a watchman to use. He must open the door, remove the key, apply
the key to his clock, replace the key, and then shut the door of
the box. As a practical matter, the key is often left dangling
beside or beneath the box, with the door left open. This unsightly
situation often results, further, in the key and chain impinging on
the wall adjacent the box. Most such installations are featured by
scratches or holes, or paint removal, from areas adjacent the watch
box. The door hinges become worn and the door itself liable to hang
in unsightly fashion, scratched or dented by the key and chain, or
itself hitting and damaging the support wall or the box itself.
Some watchclock keyholders are boxes with hinged covers, and some
are mounted in wall recesses. All are subject to inconvenience in
handling and unsightliness.
The MODEL `C` WATCHCLOCK KEYHOLDER is an entirely new concept; it
has no doors or covers to open and close or boxes in which to hang
the key and fold the chain. The Model `C` WATCHCLOCK KEYHOLDER is
simple and has no moving parts. In one form, it consists of a
vertical stainless steel 1/2 -inch I.D. tube 101/2 inches long in
which a watchclock keychain with a brass weight fastened to it is
enclosed; when the key is returned to a 3 inch vertical slot in the
rear top of the tube, the brass weight pulls the chain down into
the tube. The vertical tube is supported by two horizontal 1/2
-inch O.D. tubes, 1 inch long, which are attached 3 inches from the
top and 3 inches from the bottom of the tube. They project out from
a 3/16 -inch stainless steel plate 12 inches high by 11/2 inches
wide which is attached to the wall by two screws.
Improvements of this invention over prior art watchclock
keyholders:
1. APPEARANCE--The simple, modern design of the MODEL `C`
WATCHCLOCK KEYHOLDER will blend with the esthetics of any office or
decor. The stainless steel finish should blend well with the trim
of the appointments of the office or building in which it is
installed.
2. ADVANTAGES--It does not damage the wall when the key is allowed
to swing free, as it will strike the tube or baseplate. Even when
not returned to the holder, the unit is still neat-looking.
3. DURABILITY--There is nothing to wear out as there are no moving
parts; there is no paint to chip and there is nothing to rust or
oxidize. It is very strong and durable, being made of heavy-gauge
stainless steel.
4. APPLICATION--It is much easier to use. The chain does not get
twisted because the free-floating brass weight at the end of the
chain keeps it straight.
5. VERSATILITY--It is easy to install, with only two screws to hold
it to the wall, and can easily be moved to a new location if
desired.
6. COST--Since it is made of stock stainless steel tubing and flat
stainless steel baseplate and is simple to assemble, it provides a
quality device at low cost.
Other objects and advantages of this invention will be in part
apparent and in part pointed out hereinafter and in the
accompanying drawings, wherein:
FIG. 1 is a perspective of a watchclock key station according to
this invention;
FIG. 2 is a side elevation of the structure of FIG. 1, with the key
and chain within the storage tube;
FIG. 3 is a central vertical section of the structure of FIG. 1,
broken horizontally;
FIG. 4 is an alternate form of the top of the storage tube of FIG.
1, showing a flared top opening side slot for receiving the key
tab; and
FIG. 5 is a schematic top view of the storage tube and key therein,
according to this invention.
FIGS. 1 through 3 thus illustrate one form of this invention; FIG.
4 is an alternate structure; and FIG. 5 schematically illustrates a
concept generic to all forms of the invention.
In FIGS. 1 through 3, a vertically disposed storage tube 10 is
mounted on a wall panel 11 by horizontal support legs 12. The
rectangular panel 11 is secured to a support wall (not shown) by
screws 13. An assemblage of a chain 14, a key 15 on the outer end
of the chain, and a weight 16 on the inner end of the chain, are
stored in the tube 10 when not in use.
FIG. 3 illustrates such storage, with the weight 16 at the bottom
of the tube 10, supported by a turned-in lip 17 of the lower
opening of the tube. A turned-in lip 18 of the upper opening of the
tube prevents the key assemblage from being fully removed from the
tube by restraining the weight 16 when the chain 14 is fully
extended.
From the top of the tube 10, a downwardly extending slot 19 is
provided on the back of the tube to receive the lateral tab 20 of
the key 15. Thus, as in FIGS. 2, 3, and 5, the shank of the key is
fully within the tube when stored, while the tab 20 extends
laterally out of the back of the tube so that it is readily grasped
for removal, although essentially hidden while stored. The slot 19
is, in FIG. 1, shown as formed with straight, essentially parallel
walls, while the alternate structure of FIG. 4 shows the slot 19
with a flared, widened top opening 21 as a means of providing
easier storage of the key 15.
Thus, as in FIG. 1, the key assemblage may be withdrawn and applied
to a watchman's clock 22 to register the time at that watchstation.
If for any reason, the key assemblage is simply dropped, or not
restored in the tube, the chain length is such that the key 15 will
ordinarily bump against the stainless tube 10, and not the wall to
which the panel 11 is secured.
The key 15 ordinarily has some form of identification number or
symbol thereon (not shown) to identify the watch station to which
it belongs. This number or symbol is made part of the record within
the clock 22 when the key is inserted and used therein.
This invention, therefore, provides a uniquely useful watchkey
station device, which is simple, decorative and sturdy, and in
which the key-and-chain assemblage is essentially fully hidden when
stored, and yet presented for easy access and removal, and simple
and easy restorage. The key assemblage, including the weight 16 is
easily rotatable within the tube 10 so that the chain does not get
knotted or jammed even with repeated or unusually twisting use.
