This invention relates to cinematographic cameras, more particularly to the type adapted to be driven by spring motors or clockwork mechanisms, and principally intended 5 to be used by amateurs. 1

` ln apparatus of the character mentioned, it is universally recognized by those skilled in the art, that lightness, compactness, ease and convenience of operation, eiiciency and l@ simplicity of construction, are 'of utmost importance, since in making exposures, the

camera is generally held in the hands of the user and not supported upon a tripod or similar device.

riChe invention, therefore, has for a primary object to provide a cinematographic camera wherein, by means of the novel construction,

combination and arrangement of parts, the

features above enumerated are realized to the greatest possible extent, the contemplated novel construction, combination and arrangement of parts, permitting the size of this apparatus to be materially reduced and the driving works with the necessary regulating mechanism therefor greatly simplified.

Another important object of the invention resides in the provision of a cinematographic camera driven by a spring motor, wherein the motor and the necessary regulator therefor are mounted in'parallel` relation to each other, andhave their parts so co-related that the entire device possesses a maximum degree of compactness iand rigidity which greatly enhance the proper and efficient working of the device.

Other important objects and advantages of the inventionwill be in part obvious and in part pointed out hereinafter.

ln order that the invention yand its mode of operation may be-readily understood by those skilled inthe art, we have in the accompanying drawings set out one possible embodiment of the invention.

In these drawings:

Figure 1 is a longitudinal section through a cinematographic camera driven by a spring motor and constructed in accordance with our invention, and y 2 is a sectional detail of the driving mechanism of the device with the regulator therefor. A

Having more particular reference to the drawings, wherein like characters of reference will designate corresponding parts throughout, our improved device may be stated to comprise a casing 1 designed to enclose the working parts of the camera and having one side open, said side being closed by means of the removable cover l.

Arranged within the intermediate portion of the casing 1, is an inner wall-8 and an outer wall 1l disposed in spaced parallel relation and forming a separate compartment. The inner wall 8 has a portion struck inwardly to form the chamber 13 serving for the purpose latter specified.

Mounted within the casing 1, and adjacent to the side wall thereof is a rigid plate 2 carrying at its intermediate portion a transversely arranged shaft Q extending within the chamber 13 formed by the inwardly struck portion of the wall 8, and supporting a main gear 4 provided with a collar 14 xedly secured thereto and received on said shaft 2. This main gear 4 has its outer face recessed to freely receive the inwardly struck portion of the wall 8 thereby permitting said main gear to be closely mounted adjacent the inner wall 8 within thecasing i. rllhe main gear is actuated by means of the coiled powerl spring 3 wound about and secured to the collar 14 thereof.

4through which it extends.

Supported by and in engagement with the free end of the shaft 2 extending within the chamber 13 formed by the outwardly struck portion of the inner wall 8, and paralleling the driving mechanism of the camera, is a centrifugal speed regulator or overnor 9 for the driving mechanism of t e camera,

- 20 1 13 wherein is mounted the centrifugal speed regulator or governor supported by the. ex-

' said regulator or governor being connected .to the ceiving the inwardly struck portion of thel inner wall 8 and permitting said gear to lie closer to the inner wall 8, thus taking less space, and also because of theinwardlv struckportion of said wall 8 forming the chamber tended end of the rigid shaft 2.

Likewise, the particular position of the centrifugal speed regulator or governor 9, that is, in parallel relation with the driving motor of the camera, permits to simplify the driving mechanism and lends to the entire device a maximum degree of lcompactness and rigidity thereby greatly enhancing the pro er and'eiici'ent working of the camera.

anifestly, the construction shown A and described is capable of many'modifications, and those modifications that are within the scope of the claims, weconsider within the spirit of invention.

We claim:

.1. In a cinematographicfcamera, a casing, an inner and outer wall arranged in spaced parallel relation within the casing and subdividing the latter into three compartments, the inner wall having a portionV thereof struck inwardly to provide a chamber, a spring motor arranged in the innermost compartment of the casing, a rigid support for said motor mounted transversely of said inner- -most compartment and extending Within the chamber crmed in the inner wall, a centrifugal speed regulator arranged in the intermediate compartment of the casing and carried by the extended end of said motor supporting shaft and paralleling` said spring motor, and film driving means arranged in the outermost compartment of the casing and being operatively connected to said spring motor and centrifugal speed regulator.

2. In a cinematographic camera, a casing,

- an inner and outer wall arranged in spaced parallel relation within the casing and subdividingthe latter into three compartments, the inner wall havin a portion thereof struck inwardly` to provia a chamber, a spring motor arranged in the innermost compart,

ment of the casing, a main driving gear o erated by said motor and having its outer ace wall, a centrifugal speed regulator arranged in the intermediate compartment of the casing and carried by the extended end of said motorlv supporting shaft, adparalleling said spring motor, and ilm driving means arranged in theoutermost compartment of the casing and being operatively connected to said spring motor and centrifugal speed regula or. A

3. In a cinematographic camera, a casing, an inner and outer'wall arranged in spaced parallel relation within the casing and subdividing the latter into three compartments, the inner wall having a portion thereof struck inwardly to provide a chamber,.a fixed shaft mounted transversely of th`e innermost com partment and extending within thechambcr formed Vin the inner wall, a collar freely received on said shaft, coiled power spring Wound about said collar and adapted to actuate the same, a'main driving gear xedly securedv to said collar and movable therewith,

a centrifugal speed regulator arranged in the our hands.v v
