The receiving tube is on the left and the sending tube in front. There appears to be no valve or door on the sending tube so presumably the carrier travelled by gravity. (Lamson advertisement, 1904)

Terminal at the former Arbery & Son shop, Wantage, Oxfordshire. This is a pedal-operated system with a single tube but the shape and decoration are similar to the drawing. The carrier was returned from the first-floor office by gravity into the open cradle. There is a lever on the side which presumably closes the outlet when the foot-pump is used to propel the carrier up to the first floor.

A modern version of this kind of outlet: Airmatic system at Weavers in Lawrence, Kansas

A down-discharge Lamson terminal with receiving basket from Browns of Workington, Cumbria when it was in the Cumberland Toy Museum in Cockermouth. The tube had to be widened on tight curves to allow the straight carrier to pass through - a "swollen bend". © Rod Moore, 2002

A more decorative version (note the decoration on the inlet tube) with the outlet door almost horizontal. The basket appears identical. From Hibbards, Colorado Springs.

A very fine terminal from the Birk's jewelery store in Vancouver. This has the number YD-539 on it. The fact that it bears the name "Lamson Consolidated Store Co." suggests a date between 1888 and 1912.

A similar terminal but with the maker "Lamson Company" so post-1912.

Part of a later - and much plainer - design of down-discharge terminal offered for sale on eBay. The receiving tube would be attached vertically on the left and it was known as an F-terminal because it looked like a lower-case "f".

5. Pneu-Mode terminal

This is from a Lamsons' advertisement in The Bulletin (National Retail Dry Goods Association), Mar. 1933, p. 201

This terminal at Hibbards has a down discharge outlet like (2) above but appears to have the inlet on another horizontal tube at right angles.

Terminal with two inlets. They both feed into the same tube so perhaps it is just two allow two sales assistants to despatch carriers at the same time. The LS logo with square lettering was in use in the 1930s.

A six-sided terminal housing like one at Hibbards.

A terminal from a private collection, like the one in the picture left and made of bakelite.
