April 29, 1952 A. v. L. c. DEB'RIE SUPPORT FOR MOTION-PICTURE APPARATUS AND THE LIKE Filed Feb. 23, 1950 "Illu: .v.-||||||l||l lllllllll mii/M1@ ma/@fm i? W /M Patented Apr. 29, 1952 SUPPORT FOR MOTION-PICTURE APPARATUS AND THE LIKE vAndre Victor Leon Clement Debrie, Paris, France Application February 23, 1950, Serial No. 145,644 In AFrance April 7, 1949 13 Claims. '1 This invention relates to supports for motion picture apparatus and the' like.
Motion picture apparatus, more particularly projection apparatus, is usually mounted on a support to which electrical connections lead and which, serving as the supporting base for the apparatus, is often utilized for housing the various electrical parts and/or amplifying elements. However, when this' base is placed on a table, it is usually necessary to incline the latter in order that the optical axis of the apparatus may have the desired inclination.
'Another shortcoming of existing supports is that replacement of a given apparatus involves replacement of the supportv and lengthy Vdisassembling and reassembling operations.
The present invention aims tov obviate these shortcomings by providing a novel supporting structure for apparatus ofthe'type referred to, which permits replacing, for example, one projection apparatus by another, without disassembling and reassembling electricalV connections, and 'tilting the optical axis at will without necessitating an inclined supporting table.
The supporting structure which is the object of the present invention, comprises, substantially, a cylindrcally curved cradle mounted onv a supporting base and on which is supported a slidable, matingly curved, shoe sole rigid withV the lowermost end o the projector apparatus, said soley being adapted to belatched on the -cradle in a position corresponding tothe desired inclination of the opticalaxis. This sole is providedwith elongated, parallelconductors insulated from one another and slidably contacted by'resilient contacts located in said base and projecting through an aperture formed in the bottom wall of the cradle. Said conductors, connected within the shoe with the Various wires leading from .the projector apparatus, permit the shoe sole, and hence the entire apparatus, to be removed away from the cradle and replaced lby another cna-without disassembling and reassembling electrical connections between the projector apparatus and its supporting base.
The latter, which further serves tohouse, Vat least partly, electron-operated amplifying means or/and other electrical devices, may be easily placed on a horizontal table, or it may be rapidly mounted, for example, on a standard head with the aid of a clamp collar provided at the bottom oi the supporting base.
Said electron-operated devices are: secured on Lboth sides `of ajplate located 4between thejtwo halves of said supporting base, "assembled byV means of bolts whose heads are embedded in elastic blocks to form feet which, by being acted upon manually, permit said halves and said plate to be disassembled with facility for revision and repair.
The invention will be more clearly understood by referring to the accompanying, more or less diagrammatic, drawings which illustrate, by way of example, an embodiment thereof and in which:
Fig. l is a longitudinal elevational View, in section, showing the supporting system according to the invention applied to a projection apparatus diagrammatically shown in the drawing;
Fig. 2 is a top plan view showing one half of the supporting base of Fig. l, as it appears after the removal of the projection apparatus, and a sectional plan view of the other half, showing clamping means for mounting the supporting base on a standard head; and
Fig. 3 is a sectional view of the supporting base, taken along the axis of the device for securing the projector sole to the cradle.
Similar numerals refer to throughout the several views.
Referring to the drawings, it will be seen that the upper portion of the supporting base l is formed with a cylindrically shaped depression 2 having its horizontal axis perpendicular to the vertical central plane thereof. This depression is limited, on each side, by vertical walls 3.
Machined against the wvalls 3 are two circular runways 4 serving to guide outstanding cylindrically shaped parts or skids 5, having the same radius as the runways 4, of a hollow shoe 6 rigid with the lowermost end of the projection apparatus I diagrammatically indicated by dash-anddot lines in Fig. l, its optical axis being denoted by reference 8.
It is clear that because parts 5 of shoe 6 are slidably displaceable on the arcuate runways 4, the shoe 6 and projection apparatus I may tilt so that optical axis 8 may incline in one direction or the other.
`The shoe 6 may be locked on the runways 4. by means of two angle-latches 9 vertically guided in housings provided on the outer faces of the walls s. The latches 9 may be raised for unlocking, or they may be lowered to lock the shoe 6 against the supporting base I.
The latches 9 are formed with horizontal coaxial round holes I2, and they are raised or lowered by means of two eccentrics I3, rigid with a shaft I4 passing through the holes l2 and journaled in the side walls I5 of the upper portion of l'base I.
similar parts bars are conveniently connected to the various electric lines leading from the projection apparatus, for example from the sound producing device thereof.
Connections, by sliding contacts, with ele-ctron-operated devices, diagrammatically indicated by reference numerals it and i3', disposed on both sides of the insulating plate or plates 2i, as well as with the electrical ieed lines, are ol,- tained by means of resilient contact-blades 22, each having one insulated end secured to an insulating bar 23 carried by the upper portion oi the supporting base l, while the free end thereof terminates in an inverted J projecting through an opening 2d formed in the arcuate bottom wall of the depression 2.
The contacts 22 provide also the desired contacts with the devices la and i9', these contacts being eiiected by means of resilient members 25 arixedV to the plate 2l, and heid in contact with the returns 2t of contacts 22.
There is, therefore, no wire connection to be made between the apparatus 'l and the base i, nor between the upper portion of this bas-e and the` electrical devices it, l5 secured to the plate 2l.
Side walls 2l and bottom wall 28 form the lower hollow portion of the supporting base, which portion is adapted to press the plate 2i against the lowermost edges oi the upper portion of the base l.
The three components oi the base are assembled in the following way:
Bolts 2S, passing through the bottom wall it and insulating plate 2l, are screwed into bosses 3l rigid with the side walls of the upper portion of the base l. Said bolts have their heads 32 embedded in blocks of elastic material such as rubber, forming feet for conveniently placing the supporting base on a table (not shown). By
manually turning the foot blocks 33, the bolts may be screwed up or down with great ease. They pass through spacer sleeves 3d located under the insulating plate 2l in such a way that the latter, and the dependent electrical and electron devices, may be set in convenient position, when the plate 2l is removed from the supporting base for revision or repair.
For mounting the supporting base on a tripod or standard head, the bottom wall 28 is provided with a clamp collar 55 having two clamping lugs 36 separated from each other by a variable distance 3?. A screw 353, passing through the lugs 35 and turnable by means oi a control handle 3i?, permits the collar to grip the tripod or standard head.
The collar 35 is made for example being cast on the bottom wall 28, and its movability is obtained by extending its opening formed in the said wall, through a portion of its outer periphery, as indicated by reference 52.
A cover 43, located over the collar 35, afured to the latter by means of screws it screwed into its body and passed with clearance through holes 4 made in the cover 43 to allow deformations of the collar 35.
If desired, the collar 35 may be inserted into the bottom wall 23, only a portion of the collar being secured to this wall to enable it to keep its elasticity.
It is clear that changes of detail may be made in the particular form of supporting structure, above described and shown, without departing from the spirit and scope of the invention.
It is also clear that the said supporting structure, capable of producing a desired inclination and electrical connection between a slidable arcuately shaped shoe sole and a corresponding stationary cradle supporting this shoe sole, may have application not only to motion picture projectors, but also to motion picture cameras, photographic apparatus, and even to certain electron-operated apparatus. Said shoe sole, which may be convex, for example, may be made integral with an apparatus, or it may be ailixed to the lower end thereof.
