HUGHES MACHINES. Among the earliest machines placed on theEnglish market were the Moto-Photoscope Projector(with eccentric intermittent motion) and the Moto-Bijou Camera (a rising-sprocket apparatus). Naturallyenough, the lifelong experience in lantern work of C. Hughes, coupled with two years continuous uo LIVING PICTURES. experiment, havesuperior machine, enabled himsuperseding. to produce a vastlythe earlier patterns,which therefore neednot be described indetail. The Motor-Pictoroscope, as thenew apparatus iscalled, carries all theworking parts on theinner side of a door,as seen in Fig. essential me-chanism is showndiagrammatically inelevation. Fig. 151,and plan, Fig. consists in a littleframe, G^, carrying asmall roller, G^, drivenbackwards and for-wards by a rod, F^,working from an eccentric seen on the right in the firstFigure. Every rotation of the handle causes this frameto advance and retreat fifteen times, and on every oneof these forwardmovements the rollerG^ drives the filmforward as seen inFig. 151, drawingdown exactly onepicture. This mo-tion, though rapid,is not of the natureof a sudden stroke, but is rather a nicely graduated pressure applied withdue regard to the safety of the film. This one Fig. i;o.
