To (all Lofi/om t may concer/t.'

Beit known that I, WILLIAM C. FARRAND,

Figure l illustrates a perspective ofthe ap-- paratus. Fig. 2 illus-trates a vertical section.

Fig. 3 illustrates an enlarged detail of a sectional view ot a portion cI' the actuating apparatus.

A is a frame which Inay be made ot' wood or other material, and is adapted to beatzo tached in any suitable manner to the top of the tripod or base ofthe camera, as the case may be.

B is a tube supported in recesses in the frame A and held in place by clamping-pieces O O, which are preferably made of spring metal, so that the tube may be moved backwardl y and forwardly through the frame, if desired, but preferably under pressure to hold it in the desired position.

3o D is a head on the end of the tube B, in which is pivoted a slideway E, through which moves vertically a bar or rod F, which supports a vignetter frame and shield G upon 'its upper end.

In the interior ot the tube B at the rear end is a sleeve H, to which is pivotally connected a lever I, provided with a handle J. This lever is pivoted, as at K, to a bracket Il, which is rigidly soldered or otherwise 'fas- 40 tened to the exterior tube B.

M is a rod which slides longitudinally through the sleeve H and is preferably arranged to have some frictional contact with it. This 'trictional contact may be a section of a rubber or leather tube, as shown at N in Fig. 3, which binds upon the sides of the rod M or any other suitable friction-generating device. At the forward end of the rod M and within the exterior tube B a chain or 5o cord O is fastened, as shown atI. This chain extends forwardly through the tube B and passes over a little roller or sheave Q, then downwardly, and is connected with the end of the sliding bar F. The slideway is pivoted to the head D, as at R. The sleeve H has connected with it a forwardly-extending rod H', which connects by a link I with the slideway E', as shown.

Instead ofthe link I a rigid extension from the rod II' may be provided, and instead of 6o this rod the sleeve H may be extended to the end of the exterior tube Il.

The operation of the device is as follows: The camera being properly located and the trame A attached to the tripod or camera, as the case may be, and the subject duly located the vignet-ter as a whole may be moved closer to or farther from the subject by sliding the rod B through the frame A under the springclips or equivalent devices C, as desired, and 7o then for the vertical and horizontal adjustments the handle .I may be manipulated. If pushed to the right, then its upper end moves to the left and the sleeve H, with the rod H, is drawn rearwardly, which rocks the slideway in which the vignetter is supported away from the subject, thus rendering less defined the line of the vignette, the slideway rockin g upon its pivot R. It, on the contrary, the handle .l be pulled to the left, then the sleeve 8o H, rod H', and slideway E are pushed forwardly toward the subject, and the line of the vignette is made more defined or sharp.

If the vignetter is too low or too high, the proper adjustment is attained as follows: To elevate the vignetter, thus reducing the eX- tent of the picture, the rod M is pulled to the left, whereupon the chain which passes rover the sheave or pulley Q is likewise pulled in the same direction, and the shaft or bar F is 9o moved upwardly, sliding through the slideway E, thus elevating the vignetter and cutting oft more of the body ot the subject, and by reverse movement of the rod M the vignetter is allowed to drop under the action of gravity, being held in any desired position bythe chain or cord O, and more of the body ot the subject is exposed. The frictional device N (shown in Fig. 3) is adapted to counterbalance the weight of the vignetter and Ion its rod F, so that those devices will remain in such position as they may be lett.

In addition to the movements above described by rocking the handle .I transversely of the axis of the apparatus the exterior tube I3 will be rotated upon its longitudinal axis and consequently the vignetter be inclined to the right or left, as the, oase may be, as shown in dotted lines in Fig. l, so that by this apparatus, in a simple, effective, and Convenient manner, any desired scope or position of the vignette may be obtained.

It will be obvious to those who are familiar with this art that various modifications may be made in the details of construction of this invention without departing from its essentials. I therefore do not limit myself to the special forni of parts and their arrangement shown.

I Claiml. In a vignetting apparatus, the Combination of a tube, a slideway pivoted to the tube, a shield supported on a rod which slides through the slideivay, means to elevate the shield, and means to oseillate the tube on its axis, for the purposes set forth.

i. In a vignetting apparatus, the Combination of a tube, a slideway pivoted to the tube, a shield supported on a rod which slides through the slideway, and means inelosed within the tube, when eonneeted with the said rod to elevate the shield, for the purposes set forth.

3. In avignetting apparatus, the combination of a tube, a slideway pivoted to the tube, a shield supported on a rod which slides through the slideway, means inolosed within the tube when eonneeted with the said rod to elevate the shield, and means to oseillate the tube on its axis, for the purposes set forth.

l. In a vignetting apparatus, the Combination of a tube, a slideway pivoted to the tube, a shield supported on a rod which slides through the slideway, means to elevate the shield, other means to rook the slideivay on its pivot and means to oseillate the tube on its axis, for the purposes set forth.

5. In a vignetting apparatus, the Combination of a tube, a slideivay pivoted to the tube, a shield supported on a rod whieh slides through the slideway, means to elevate the shield, and other means to roel: the slideway.

on its pivot, for the purposes set forth.

G. In a vignetting apparatus, the eombination of a tube, a slideway pivoted to the tube, a shield supported on a rod which slides through the slideway, means inelosed Within the tube for rocking the slideway upon its pivot, and other means likewise inelosed within the tube for elevating the shield, for the purposes set forth.

7. In a vignetting apparatus, the combination of a frame, a tube supported upon the frame and adapted to slide through it, a slidevWay pivoted to the tube, a shield supported upon a rod which slides through the slide- Way, a lever fastened to the tube and which engages with a sleeve inelosed Within the tube, and which engages with the slideway whereby, upon manipulation of the lever the slideway may be tilted, and the tube oseillated on its axis, for the purposes set forth.

S. In a vignetting apparatus, the combination of a tube, a slideWay pivoted to the tube, a shield supported on a rod which slides through the slideway, a lever rigidly attached to the tube and which engages with a sleeve or rod inelosed within the tu be, which in turn engages with the slideway, another rod likewise inelosed within the tube provided with a chain, ivhieh engages With the lower end of the rod which supports the shield, and a frietion device applied to said last-named rod, for the purposes set forth.
