    Companion Stoves Models 1, 5 and 5R

    Introduction

    Most Australian collectors have a good old Companion stove in their collection. Nothing epitomises an Australian made ‘Primus type’ stove more than a Companion brand stove. These stoves are common on eBay and often get polished up to attract a better price. They are well made and easy to fettle. The trivets do tend to rust out to some extent and take a while to restore. They are indeed a classic Australian stove made from sturdy brass.

    The purpose of this article is to endeavour to identify the variations that I am aware of to date. In my research I have looked at all stoves in the Gallery and many others online as well as reached Companion blowlamps.

    These suggestions are as up to date as I can get them. I am aware of some minor variations in legs and pre-heater cups, but I consider what I have put here workable but subject to peer review and updating.


    History

    Since the early 1940s, Companion Heaters Ltd manufactured several models of stoves and blowlamps, mostly based on Swedish Sievert designs. They were built to a very high standard as were the units they were modelled on.

    A brief history about the company was written in 2007 by Dr Peter Watchorn and is available here in CCS.

    Companion Heaters Pty Ltd


    Similarly, an updated article about Companion blowlamps appeared in the March 2016 edition No 94 of ‘Blowlamp News’ produced by the Blowlamp Society. http://www.blowlampsociety.com/BN94.pdf


    In 2015 I wrote some preliminary notes expressing my thoughts about the lineage of the Companion model 1 and 5 stoves and these can be found here.

    Companion (Svea) Stove

    I would point out that in the heading for that article I used the term Companion (Svea) and I would not now use that terminology as I believe they are solely a Companion stove, albeit acknowledging their licensing arrangements with Sievert in their first stoves.

    Model Numbers

    Old advertisements that I have seen generally did not specify the stoves with a model number, though such advertisements may well exist. They generally stated silent burner or roarer burner or even standard burner or silent burner. However, a maintenance kit was clearly offered and labelled as being for the Companion Model 5. See here.

    Companion 5 spare kit

    Companion brochures and instructions also regularly mentioned the models by name as Model 1 or Model 5. Companion also stuck to the model numbers used by Sievert in respect of their stoves and blowlamps that were replicated by Companion.


    General Stove Description and Features

    The Companion model 1 and 5 stoves are a standard Primus like, brass constructed, tri-legged upright stove with a steel trivet. Their flattened cylindrical founts have the words “COMPANION STOVE’ prominently stamped into each on the top flat surface. The approximate capacity of the stove is 2 pints.

    Each stove has an external pump and a filler cap combined with an air release screw. Two types of air release screw are known, a flat version embossed with names and a round knurled version.

    The legs were made of steel and generally were not detachable, excepting for the heater – stove radiator. The height of each stove is about 222 mm, but I have measured occasional variance between 217mm and 225mm.

    Companion stoves all have a standard looking filler cap with ‘COMPANION’ stamped on one side only. The washer inside is 23mm OD.

    Silent burners all have 8 holes evenly distributed around the support for the burner cap assembly.

    All pumps are similar excepting for the heaters and regulated burner model.



    Summary of Variations


    Companion/SVEA – Abt 1941 onwards - (Type 1)

    Logo has SVEA stamped on top and is not above the pump. (Key point of differentiation).

    Trivet stamped COMPANION BRAND and SVEA PATTERN

    Air screw is flat and has SVEA embossed on one side and COMPANION on other

    Burner may be made and identified as SVEA.

    Inner ring may be stamped COMPANION BRAND and bottom of pre-heater cup may be stamped COMPANION SVEA PATTERN

    Roarer burner has SVEA COMPANION SVEA marking.

    Example: COMPANION (SVEA) with Roarer Burner



    Companion (Middle years) (Type 2)

    Air Screw is flat and embossed on both sides with COMPANION

    Trivet stamped COMPANION and BRAND at opposite end.

    Logo is plain and has no words on it and is located above the pump.

    Roarer burner has COMPANION marking

    Pump is below logo.


    Companion (Possibly from c1952 onwards) (Type 3)

    As above but air screw is round and not labelled. Blowlamp ads have this round air screw visible from at least June 1952. (Sydney Morning Herald – 26 June 1952). The stoves were made through to around the late mid-sixties; maybe even a bit later.

    Some type 3 units have several ridges near feet, possibly from manufacturing.

    Pre-heater cups are often marked with just the word COMPANION’

    Example: My 2nd Companion stove


    Companion Heater/Stove Model 5C (Type 2H and Type 3H)

    Generally, taller (est 270mm high) but similar with Types 2 or 3 but with a reflector and heat spreader steel dome.

    Pump knob has an integral reserve cap for transport.

    Fount may be nickel plated.

    The rolled engraved large words on fount have horizontal etchings within letters.

    Legs are detachable.

    Obvious support ring with legs below the fount attached to the ring. Early support rings are wider. Later ones are thinner. See both examples here: Companion Heater/Stove


    Companion Regulated Silent Burner (Model 5R)

    This unit has been shown in the gallery by Tony Press here.

    Companion: Regulated Silent Single Burner

    I consider it best identified as a Companion stove Model 5R which was probably made parallel to the Model 1 and 5 (Type 3) units. Initially I was inclined to considering it as a Type 3R but as the pump is plastic and the pump outlet is significantly longer than on other models, so I think it is quite different.


    Footnotes;

    (1) 80% of a sample of over 20 Companion blowlamps, displayed online, have the round air screw suggesting they are the later models. Additionally, all older ads show the flat air screw. However, and this is a big ‘however’, the Sievert model blowlamps (Sievert 42 and Sievert 43), that the Companion 42 (1pt) and 43 (2pt) are based on actually have the round air screws. Puzzling why the early Companions had flat air release screws. Also, the Sievert 43 has not yet been found; only in images and documentation.

    Nice bit of work. :thumbup:

    I’ll have to go out to the shed and dust off my Companions.

    I’ve got a few in storage in Melbourne that I picked up last year (maybe even the year before) but have been unable to cross locked borders to collect.

    Cheers

    Couple quick corrections. I should read things more carefully.

    1. In the general description. I actually meant the pump is attached to the fount; not external such as in a separate device.
    2. I also forgot to mention that in the Companion Instructions the publisher is often mentioned as The Specialty Print Limited (this is after mid 1951) and prior to that they are listed as The Specialty Print Pty Ltd so this information can assist in determining the age of the publication.

    My first post on CCS with some additional information on Companion though only a little.

    The Melbourne Times Wed 9Aug1950 Page 61 shows Companion Heaters Pty Ltd at 450 Collins Street, Melbourne (Source - Trove).

    A search of Sands & McDonalds Directory of Victoria & Canberra, ACT 1944-1945 (Accessed via State Library of Victoria) shows them at the same address listed as "Kerosene Stove Mnfrs"

    My family used a Companion stove to cook on in the 1950s and 60s. Dad said the kero stoves were better than the wood stove in the very hot Australian summers as it didn't heat the house up as much.
