— 78 — The pad from which the ink supply was derived was contained in a metal case, which fitted closely round the top plate of the machine and the types, when at rest, lay imbedded in this pad. It is a curious fact, little known to Yost operators of to-day, that in the earlier models, this pad was made in two portions, but this duplex arrangement soon gave way to the single pad. Moreover, it is interesting to note that the earlier models of the Yost were made with a variety of keyboards, that is, the keys were arranged in such ways as to suit old-time operators of the Caligraph, the Hammond, or the Remington, the latter, of course, being in duplicate. Fig. 6i The accompanying sectional view of the type-bar of this early model will interest those who like to know how the machine worked. On the depression of the key, K, the key lever, F, is pressed down at the key end, and, swinging on the central fulcrum shown, is raised at the type-bar end. This movement pushes up the connecting rod, C, causing the type, D, to leave the ink-pad, P. The movement of the type can then be easily followed, as it finds its way to the guide, G. The link-holder, L, is a fixed point, and it is this that gave the machine its peculiar and rapid stroke. The centre-guide has been the subject of a great many discussions. The opposing party say that absorbs power, that is, that part of the force of the blow is dissipated the moment the type comes in contact with the guide, and that consequently, either a heavier blow was necessary than need be to secure a good impression, or that the impression was not perfect. It was considered, also, that ink was taken from the type-face and gathered round the guide, which afterwards found its way on to the
