Description Notes

Hutton’s Graphic Projector for solid & descriptive geometry, by T. Laurie, English, c. 1900.

A didactic outfit with three dimensional model for demonstrating projective geometry.

The set contains (A) Horizontal & Vertical Planes, one Auxiliary Square Plane, and Book of Instructions, (B) Two Auxiliary Transparent Planes one square and one rhomboidal. Also included are two metal assembly rods with elastic bands.

The Horizontal and Vertical Planes are in the form of a circular piece of card folded down the middle with a small hole in the centre. If described as a clock face V.P. is marked at 12, Y at 3, H.P. AT 6 and X at 9. Around the edge of the circle degrees are marked. The circle has been dived into for with 0 - 90 marked in each quarter. The light blue background of the circle is squared to help with accuracy of measurements. The covering is made of a light material, it is held to the hard cardboard back with two stapes at each side.

On the reverse of the Plane circle there are two pink labels, one on each half. The top label is titled ‘HINTS FOR USING’ whilst the bottom is titled ‘TO ERASE’ and lists the ways in which various forms of media should be removed from the surface to avoid damage to the projector.

The square auxiliary plane is light green in colour with four small leather loops, two on two sides. These are held in place with metal rivets and are used to secure the elasticised metal pins. Like the background of the Vertical and Horizontal planes the auxiliary plane is squared.

The two transparent auxiliary planes (square and rhomboidal) are red and orange respectively. The have the same small leather loops as the square auxiliary place.

The box also contains a set of instructions. At the bottom of the front page the date 1896 is printed below the address of the ‘EXPRESS AND STANDARD OFFICES’, BLACKBURN, 41, CHURCH STREET.
