VIGNETVTER. j r

7 Be it known that I, FRANK W. GRAY','of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Vignetters'; and I do hereby declare the following to be a full, clear, and exact description of" the same,

reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked" thereon. p

My present invention relates to photo'graphy and more particularly to vig- ,netters and it has for its object to provide a simple, cheap and convenient device of this nature that willbe light and serviceable and may be attached readily toany convenient part of a camera or camera support. I

The improvements are directed toward providing for a universal adjustment of the mask that can be readily effected by the operator practically with the use of only one hand. u

To these and other ends llllG'lIlVGIltlOl'l resides in certain improvements and comblnations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claim at the end of the specification. y

In the drawings: Figure 1 is a side elevation of a camera to which has been applied a vignetter constructed in accordance with and illustrating one embodiment of-my invention; Fig. 2is atop plan view thereof; Fig. 3 is a front view of the mask and its immediate support; Fig. 4 is a detail sec tion through the supporting clamp taken on the line 4"4 of Fig. 1; Fig. 5. is a detail section through the clamping nut taken on the line 5 '5 of Fig. 1; Fig. 6 is a detail section through the mask holding clip taken on the line 6"6 of Fig. 3, and Fig. 7 is a perspective view' partly in section of the mask holding clip.

Similar reference numerals throughout the several figures indicate the same parts. Referring more particularly to the draw ings, 1 indicates an attaching clamp that is shown applied to the bed 2 of a camera. The clamp may consist of the 'usualyoke and thumb screw 8, but it carries on its connecting portion 4 a rigid headed stud 5 that forms a pivot for a supporting rod 6 having an eye 7' at its end encircling the stud be neath the head 8 thereof. The spring plate 9 Patented Feb. 1, 1911:.

rotation by centering projections '10 engaging notches therein, thrusts the eye7 against the head 8 and creates a frictional. Contact by. virtue ofwhichthe supporting rod will b L i Q He'd t any position to which itis aduisted m a vertical plane; A I

Extending transversely of the supporting rod 6 is a mask holding rod 11 and the respective rods occupy right angle communicating channels 12 and 13 in a clamp nut 14 arranged at their junction so that the A set I rods are in contact with each other. screw 15 cooperating with the nut is adapted to engage one and clamp it against the other,

as shown in Fig. 5. Both the rods and the channels they occupy are circular so that the former are rotatably adjustable as well as loosened.

The rod 11 has an eye 16 at its outer end which encircles as a pivot a rigid stud 17 on oneof the plates 18 of a spring clip for the usual serrated mask 19. The other plate 20 of the clip which is centered in the superposed relationship by suitable lugs 21 oocupying notches in the opposite edges of plate 18, is formed with cutaway portions 22 that give outline to an integral embossed spring washer 23 located within the body of the plate and preferably slotted as at 24 to give greater resiliency. The beforementioned stud 17 extends through the washer E23 and the eye 16 is confined between the latter and the head 25 of the stud so that'the washer presses against the eye and offers a frictional resistance to the rotation of the rod 11 on its pivot, or rather, to the rotation of the clip 1820 upon the rod. It therefore maintains itself readily in any position of adjustment to which it is moved.

The general operation of such a device is well understood in the art and needs no explanation here. Turning the rod 6 on its pivot 5 raises and lowers the mask 19 as does the rotation of the rod 11 and nut 14 upon the rod (3. The mask may be further rotated laterally in its same plane on the pivot 17 of the clip and may be tilted to the front or rear by rotating the rod 11 in the nut.14 while sliding the nut on the rod 6 carries the mask forwardly or rearwardly along the axis of the lens.

It will therefore be seen that a positively universal movement is allowed the mask and I also-carried on the stud andprevented from' slidable longitudinally when the set screw is I it is further pointed out that While the operator is using one hand to focus the camera, 'he can, by grasping only the set screw 15 With the other hand, move the mask to most any desired position of adjustment with the single exception of rotating it on the clip pivot 17. Because of the spring-friction pivots, it will remain in the position to which he moves it as he imparts a final twist to the set screw 15.

The device is composed largely of stampings and can be produced and assembled very cheaply.

I claim as my invention:

In asphotographic vignetter, the combination With a clamping nut, of asupporting FRANK WV. GRAY.
