The 246X Pattern Navyphones were a family of Graham navyphones (patterns 2461, 2461A, 2462, 2463, 2464, 2465 and 2466) introduced to service at the dawn of the Super-Dreadnought era for service in Orion. They were powered by motor generator supply and were meant to replace the variety of older instruments recently deployed.
This family used a reliable buzzer rather than a ringing bell as a means of drawing attention to an incoming call, permitted voice call-up, and a new Marzi pattern receiver (excepting patts 2462 and 2466).[1]
Otherwise, the advantages offered were cited as:
- retention of previous pattern virtues
- addition of a visible "lamp signal" (except in the cabin model, pattern 2462)
- louder and more reliable buzzers in lieu of bells
- use of an alloy ("Suphalium") to reduce weight
- removable mouthpieces for cleaning
As shown in Annual Report of the Torpedo School, 1910. It looks like an enforcer 'droid. The eyes are a push to call on the left and a call indicating lamp on the right. The lower circle, the receiver horn, the arms have receiver cups on the end, and the torso is a transmitter cone.

This was billed as a "universal navyphone" and a suitable replacement for between 6[2] and 9[3] previous phones:
- Pattern 2140A Navyphone
- Pattern 2108A Navyphone
- Pattern 2108B Navyphone
- Pattern 2109A Navyphone
- Pattern 2109B Navyphone (not mentioned in TDB 1914)
- Pattern 860 Navyphone (not mentioned in TDB 1914)
- Pattern 862 Navyphone (not mentioned in TDB 1914)
- Pattern 863 Navyphone
- Pattern 1856A Navyphone
It first appeared in Orion.[4] It might be telling that the earlier source cites more roles for it than the later one.
Form Factor
The device appears to be the union of all prior phones in its physical presentation: call-up push, a new call indicating lamp, an underslung receiver horn, a pair of movable receiver arms, a front-mounted transmitter. See the images — it looks like an exercise gym set.
A push-to-talk speaking lever beneath the mouthpiece moved aside a solid shutter over the transmitter to reveal a perforated grill and also served to agitate the carbon granules in the transmitter.[5] The right-hand receiver arm activated a switch for answering as in earlier models. The phone weighed 14.5 pounds.[6]
Service Life
There is not much information in this regard, but it may have been superceded by the 2461A soon after introduction.[7] It is not clear whether this or later models ever replaced existing installations.
These phones were variants of the 2461 with a means to attach an external bell. It appears these supplanted the 2461 immediately after Orion.[8]
Form Factor
As 2461.[9]
Service Life
It is not clear whether this or later models ever replaced existing installations.
As shown in Annual Report of the Torpedo School, 1910. It has the modern style handset similar to that in the Pattern 541 Navyphone.
This is a very modern-looking handset phone for cabin use. It first appeared in Orion.[10]
Form Factor
The device is a small cylinder mounted on the bulkhead with an L-shaped corded handset on a cord resting atop it (or possibly on the left, though I think the image may be rotated) in a hang-up cradle. Its weight was 5.5 pounds.[11]
Service Life
This device may have been superceded by a model in the 333X line beginning with the Queen Elizabeth class.
As shown in Annual Report of the Torpedo School, 1910. It has the modern style handset similar to that in the Pattern 541 Navyphone.
This fire control navyphone for use in Transmitting Stations first appeared in Orion.[12]
Form Factor
The 2463 used the same case as the 2461 phone, with the call-up push and call indicating lamp facing out. Under this chassis was a squat sound horn for the receiver, and a hook in front permitted the handset to be hung in place. A cable gland was provided to permit the optional installation nearby of a pattern 2465 special transmitter, which would be used when a pattern 2463 in the TS were wired to a pattern 2464 in a gun turret. The device weighed 7.625 pounds.[13]
Service Life
This device may have been superceded by a model in the 333X line beginning with the Queen Elizabeth class.
As shown in Annual Report of the Torpedo School, 1910. Notice the second receiver that distinguishes it from the pattern 2463.
This fire control navyphone for use at gun positions, conning towers, control towers, and control tops first appeared in Orion.[14]
Form Factor
This was identical to the 2463, but a second receiver was clipped on the back of the main handset receiver, and could be removed to be cupped over the other ear (or another's ear) if desired. It probably lacked or did not actively employ the means of wiring up a pattern 2465 transmitter in tandem.
Service Life
This device may have been superceded by a model in the 333X line beginning with the Queen Elizabeth class.
As shown in Annual Report of the Torpedo School, 1910. Notice the second receiver that distinguishes it from the pattern 2463.
This was not a navyphone in and of itself, but a transmitter to be used in conjunction with a pattern 2463 navyphone mounted in the transmitting station. It first appeared in Orion.[15]
Form Factor
The 2465 was a transmitter on a hinged stem that was kept swung back against the bulkhead by a spring, which broke its circuit connection to the 2463 navyphone to which it was connected. By swinging it out from the wall, the connection was made and instant use could be made of the voice call-up feature inherent in the 246X design.
Service Life
This device may have been superceded by a model in the 333X line beginning with the Queen Elizabeth class.
As shown in Annual Report of the Torpedo School, 1910. It lived in a very well waterproofed box and was therefore most suitable for use in destroyers and exposed positions.
It may have first appeared in Orion.[16] It's not clear in what manner it may have been supplied to destroyers and other ships manufactured prior to Orion.
Form Factor
The handset resided in a watertight box and had a second receiver clipped on the back of the handset receiver (as in the pattern 2464). When the phone was in place in the box and the cover closed, a trumpet in the box lid faced the handset receiver to amplify the buzzer or voice call-up feature. The entire assembly weighed 16.75 pounds.[17]
Service Life
This device may have been superceded by a model in the 333X line beginning with the Queen Elizabeth class.
