Description Notes

Set of 12 card descriptive geometry models, by Thomas Jones, published by John Heywood, English, c. 1893

Set comes in cardboard box with a slide-on/off lid. On the front of the box is the label as well as a handwritten name of (presumably) the owner: H. W. Everitt. The rear of the box shows an index to the models, of which there are two series, with six in each series. The box contains 12 card models, folded and connected with string, as well as seven paper insert advertisements or instructions and one folded piece of card in the shape of an equilateral triangle (which may be handcut).

The twelve models are folded in the middle and have string and cut-out features to create working models. Series one has six models:
1. Line represented by its projections.
2. Line represented by its races.
3. Oblique plane and the angle it makes to the V.P.
4. Oblique plane and the angle it makes to the H.P.
5. The angle contained by two interesecting lines.
6. The angle contained by two intersecting planes.

Series two also has six models:
7. Oblique plane and its trace on a 2nd V.P.
8. Triangle with its plane inclined to the H.P.
9. Line represented, its angles to the H.P. and the V.P. being given.
10. Two oblique parallel planes at a given distance apart.
11. Line of a given inclination parallel to a given plane.
12. Given two lines, not in the same plane, draw a plane containing one line and parallel to the other line.

Inserts include an advertisement for Thomas Jones’ working engineering models which is four pages and includes a description of the contents of the sets, quote endorsements from ‘the press’, reduced-scale illustrations of the models and on the rear a list of Jones’ Engineering publications. Another advertisement, also four pages, focuses on Jones’ Engineering publications, ensuing book on Machine Drawing, current book on Machine Drawing, working engineering models and descriptive geometry models. A third advertisement focuses on the Machine Drawing book I and book II part 1 (Machine Tools) as well as a book on Practical Geometry. The interior of this insert contains illustrations of a locomotive coupling and connecting rod ends, assumedly from the Machine Drawing or Machine Tools books. Pink insert advertises the Geometry Models.

Additional to these advertisements are three inserts specifically pertaining to the geometry models. Two of them contain ‘Hints for Fixing and Studying the Models’ and address series one and one series two separately and the third lists ‘Problems suggested as Exercises for the Student’.

There is also a card triangle contained in the box which can be folded into a pyramid. The box also contains two iron lips for the supporting of the models.

Condition: fair, complete. The contents are in fair condition, some light damage. The box is in fair/poor condition as is well worn with significant light damage and some parts are torn.
