I Application filed October 18, 1911.
Specification of Letters Patent.
Patented June 17, 1913.
Serial No..655,340.
To all whom it may concern Be it known that I, ERNEST ALBERT Iva'rrs, citizen of GreatBi-itain, residing at Paris, in the Department of the Seine, and Republic of France, have invented certain newand useful Improvements in and Relating to Toothed Film-Operating Drums of Kinematographic Apparatus, of which the following'is a specification.
This invention relates to toothed film operating drums for kinematographic apparatus.
The objects of the invention are to provide, first, for rapid and easy interchangeability of the drum by the operator without requiring the use of special tools or the services of a skilled mechanic; second, to obviate scratching the film when it is threaded onto the drum.
The invention'consists in a toothed film operating drum mounted for bodily shifting and a clutch adapted for coupling said drum to the Maltese cross or other drum driving means.
The invention is shown in the accompany-- ing drawing,in which:
Figure 1 is a sideview of the drum. Fig. 2 is a longitudinal section. Figs. 3 and 4 are end views.
teferring to the drawing it will be seen that the toothed drum 1 is mounted by its journal 2 in a dismountable or s'hiftablebearings 9 and to which is keyed the Maltese cross 10 rotating the toothed drum 1 The invention resides in the provision of a bodily shit'table toothed film-operating drum, and a clutch for controlling its rotation', rather than in the specific clutch employed. 1
According to the displacement of the drum 1 and its support 3, the parts will be coupled up (Fig. 1) or uncoupled (Fig. 2).
The drum may be quickly removed by shifting the bearing 3, and another substituted when repairs are necessary, without requiring special. tools or the services of a skilled mechanic. The shiftability of the drum minimizes scratching of the film when threading it thereon, as the drum may be quickly positioned for convenient placing of the film thereon which cannot be done with the drums now commonly used.
It is evident that-modifications may be introduced in the arrangement without in any way affecting the principle of the invention Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, I declare that what I claim is 1. In a kinematograph, a bodily shiftable
