I 1 _ This invention relates to photography and par ticularly to a photographic out?t which will en able relatively unskilled operators to make photo graphs of objects at ?xed magni?cation under ?xed lighting conditions. One object of our in vention is to provide an apparatus which can be readily supported by an operator to take pictures (Cl. 88—.24_)~ 2 ture, since the lighting conditions can always be maintained the same and in which separate focus ing forv each photograph is unnecessary. To ac complish this, we prefer to provide a support, in the form of an elongated base member I, which is preferably made 'long'and narrow. Near the ‘cen tral part of this base member there isa means 2 for supporting a camera 3, this means carrying a tri of small objects, such as tools, flowers and the pod screw 4 by which the camera is attached to the like, and to provide a means which will simplify producing such pictures. Another object of our 10 block. On each side of the camera 3 are mounted invention is to provide a hand-held camera sup port so arranged that it can be used with either one or both hands of an operator and to provide a support in which the various cooperating parts lamps, such as ?ood lamps 5, these beingv carried by suitable sockets 6, the sockets‘ in turn being carried by brackets ‘I. The brackets ‘land lamps 5 are so shaped that they may be swung upon arewall carried in convenient operating positions 15 shaft portions 8 which pass through the ends of the base I and they may be fastened at any;.de so as to reduce the number of operations in tak sirable angle by means of the wing nuts ‘9.

Another object of position and shape of the brackets 1 is such that our invention is to provide a device which is read there is but little change in the balance of the ily portable for photographing small objects and to provide a single self-contained unit which will 20 support I regardless of the positioninto'which these brackets are swung. > ' ‘ ' _' ' carry all of the necessary parts for producing ex On each side of they camera 3 we provide rod posures. A still further object of our invention supporting apertures H) as shown in Fig. 5, these is to provide a support carrying frames which both apertures passing through the support VI’.

That is, we these handles 25 being mounted near the center provide a camera which can conveniently be al of gravityofthe support I with its various at ways operated at a ?xed speed and a given aper 2,403,892 3 4 tachments and the other handle 26 being mount ed nearer one end of the support I. The location ried by the support 62 on which the camera 63 is also carried. of these handles is important, because it enables an operator to support the entire photographing out?t readily with one hand by grasping the han tary lens ‘64 of the desired power and, since the rods 54 are accurately positioned on the base dle 25 and to use the handle 26 for guiding the member 62 in a manner similar to that described The upper cross bar 51 supports a supplemen base I with its attachments into the desired posi tion. In addition, while holding the out?t by the for the embodiment shown in the first four fig ures, the supplementary lens 64 is always coax ially positioned with respect to the camera lens handle 25, it is a. simple matter to wind ?lm through the camera by means of the usual wind 10 carried by the shutter 66.

We also since the supporting board 55 is preferably prefer to mount an operating plunger an for a painted a neutral gray and since a glass panel 58 cable release 3| attached to the camera shutter supporting the work W to be photographed is used 32 for operating the shutter and to provide the above this base, the lamps illuminate the back— operating plunger 3|] either directly on the handle 26 or on an adjacent part of the support I. Thus 20 ground and provide a picture of the work W which is clearly set out from the background, and the the operations of lighting the lamp and making shadows cast by the work W are beyond the field the exposure can be carried out while steadying of view. Of course this type of device cannot be the out?t by holding it with both handles 25 used in many instances, as where it is necessary and 26. The operation of taking pictures with the out?t to photograph a piece of work being turned on a as thus far described is extremely simple. Since the illumination of the ?ood lamps 51s always the same for the ?xed distance determined by the frame 20, an operator merely supports the out?t by the handle 25 steadying it with the handle 26 and lowers the frame 20 until it partially sur rounds the object to be photographed and until lathe, for instance, or some other part which is inseparable from its surroundings. In such a it approaches or lies in substantially the same plane as the article to be photographed. When so positioned, the light switch 28 is turned on and the cable release plunger 30 is depressed, thus making an exposure. This operation can case, we prefer to use the embodiment of our in vention shown in Fig. 1 in which the model frame 28 defines the ?eld of view and focus. In Fig. '7 we have shown a slight modification of our field de?ning frame and, in this instance, two downwardly extending rods 10 are employed, these rods being connected by a crosspiece ‘H carrying a supplemental lens 12. At the lower end of these rods there are turned-over portions 13 to which the end members 14 of a generally U-shaped frame 15 are attached by means of be carried out by laying an article to be photo pivots 1B.

Thus an article W to be either side of the plane of the frame 20 or 58 photographed is held in a position in which it and because the shutter speed of 1/50 of a second may be illuminated by the lamps 60, these lamps is su?iciently short to permit an operator to take being carried by ‘the adjustable brackets 6| car a picture while holding the out?t in his hands 2,403,892 5 without shaking the camera. In both the em bodiments of our invention we may point out that of small objects including a support adapted to be supported by hand and comprising a long, by having one of the handles 25 at substantially the center of gravity of the out?t, it is possible thin, rod-like base, a screw for attaching a cam era with its lens and shutter to a medial portion of said base and with the lens axis transverse to support the out?t by one hand without undue di?iculties, this being useful not only in taking pictures, but particularly for winding ?lm be tween pictures. The handle 26 also is usually used to help support the, out?t because of the to the length of the base, a pair of lamps, lamp brackets movably mounted on the ends of the base and to both sides of the camera-attaching screw, handles for supporting said base extend added steadiness that the use of two handles usu ing from the base at an angle thereto, a lamp ally gives.
