VIEW-lVl ETER.

SPECIFICATION forming part of Letters Patent N o. 685,839, dated November 5, 1901. Application filed March 28, 1901. Serial No. 53,237. (No model.)

To all whom it may concern:

Beit known that I, ANTHONY HEGER, a-citizen of the United States, residing at Washington, in the District of Columbia, have invented newand usefullmprovementsin View- Meters, of which the following is a specification.

This invention relates to photography, but more particularly to a view-meter therefor; and the primary object thereof is toprovide a cheap, durable, and efficient means for determining the extent of a landscape or object to be photographed which will appear upon the ground glass or plate.

A further object is to provide a View uder and meter combined which will b e interchangeable for different-proportioned plates from the smallest to the largest, and thus overcome the necessity of employing a separate and distinct view-finder for each and every camera.

A still further object is to. provide means for accommodating the meter to lenses of varyingangles-such, for instance, as an ordinary-view lens or a wide-angle lens used for interior work.

With these objects in view my invention consists in certain novel parts and combinations of parts, all of which will be described hereinafter, pointed out in the claims, and illustrated in the accompanying drawings, in which-- Figure 1 is a perspective view of the preferred form of my invention. Fig. 2 is a vertical longitudinal sectional View through the same. Fig. 3 is a detail View of the sightingdisk. Fig. 4 is a sectional View of the slideplate and regulating-slide on the line 4 4 of Fig. 2. Fig. 5 is a perspective view of a modifled form of my invention. Fig. 6 is a horizontal sectional View of the same. Fig. 7 is a rear end view, and Fig. 8 is a perspective View of a still further modified form.'

Referring now to the drawings by numerals of reference, 1 designates a graduated bar, on one end of which is a front support or standard 2, carrying a disk 3, in which is provided a concentric opening or perforation 4, through which the operator sights the View. A pivoted shutter 5 is carried by the disk 3 and is adapted to be moved over the opening 4, so that the minute perforation 6 will register with the center thereof. The purpose of this shutter will be explained hereinafter.

On the free end of the bar l is sleeved a rear support or standard 7, adapted tobe secured rigid thereto through the medium of a setscrew S. The free end of the support erstandard carries a vertical slide-plate 9, provided with a rectangular opening 9a in its face,which alines with the sight-hole 4 in the disk 3. `This rectangular opening may be enlarged or decreased through the medium-of a slide 10,f

movably secured to the plate 9 by guide-plates 10a, so that the relative proportions of the width and length of said opening may be varied to coincide with the proportions of the plate upon which the exposure is to be made. It will be noticed that a plurality ot' graduations (designated by the reference -numeral 11) are arranged upon the inner guide-plate of the slide and are adapted to register with an index-point l2 on the slide-plate 9. If'it is desired to malre an exposure on a square plate-say three and one-half by three and one-half, four and one-half by four and onehalf, or ten by ten-the lower graduation will be caused to register with the index-point 12, thus causing a square opening-to appear in the slide-plate 9. The rear support or standard will be adjusted toward or away from the sight-disk as may be necessary on account `of the angular focal depth of the lens used, and the object or objects appearing to the eye when applied to the sight-hole 4 and .through the opening 9a will be the subject-matter of the photograph. If it is desirable to take a picture of oblong formation, the slide will be adjusted to cause one of the plurality of graduations to register with the index-point on the slide-plate 9, the particular graduation utilized being governed by the proportions of the plate te be exposed. Thus, for instance, if it is desired to expose a plato five by eight or of similar proportions the slide will be forced down to cause the uppermost graduation to register with the indexpoint. the next graduation to be adjacent the indexpoint, and so on.

In the ordinary-view lenssay an angle of twenty/eight degrees-the slide-plate 9 will be farthest from the disk 3 and the opening 4 therein will be utilized. However, when a A live-'by-seven exposure will require IOO l2 f A desastre wide-anglelens is employed the shutter 5 will be moved tothe position shown in Fig..3, so

as to describe the viewfof the eye through the inclusive, 13 and li designate two telescopicA supports'or tubes sliding one Within the other. The front support or tube 13 is closed at one end except-for an opening 15, concentrically "the `side of the support or tube.

In'Lthe modifiedforin shownin Fig. S, 2O and 21 designate two jointed arms pivoted together at their outery ends b vapi vot 22. These armsl at their inner ends carry the sightdisk and be suitablyspaced apart by the transverse graduated bar 23, projecting from the arm 2O and passingthrough the slot 2l in the arm 21. E From the foregoing :it will readily be seen that `I have provided acheap, durable,`and efcientview-meter which maybe readily accom mod-ated vto'any of the standard cameras, and while `I have shown the preferred form of m'yinventionfI do not limit'myself thereto, b ut would have it understood that I reserve the right to make allsuch changes and modifications `as fairly'fall within the scope of the invention.v j

What I desire to claim and secure by Letters Patent is- 1. A lphotographic view-meter comprisingY 2. A photographic view-meter, comprising a diskhaving a sight-opening, an adjustable These armsl may slide-support arranged adjacent thereto and provided with a rectangular openi ng,'and a slide whereby the size and. proportion of the opening is adapted to be regulated. 'l

3. A photographic view-meter comprising a bar, a perforated disk arranged on one end thereof, a sliding slide-support secured thereonadjacent to disk, said disk and support having alining openings and the shutter and slide whereby't-he sizes of the respective openings are adapted to be regulated.

g 4; A photographicl View-meter comprising asight-disk, a shutter having afperforation of lesser diameter than the opening in the disk, and a'slide-support'adjustable toward and away from sight-disk, having a rectangular opening and a slide for regulating the latter. l 1 Y 5.v A 4photographic `view-meter 'comprising atransverse bar, having grad'uations, a disk Arigidly carried at one ,end'thereoii andv having a sight-opening, and a sliding sleeved vstandard tosaid bar adapted to be adjusted toward and away fromt'he disk `and having a rectangular opening carrying a1slide'plate and a slide whereby the size and proportion of the opening is4 adapted-to be varied.

6. A photographic view-meter comprising ya graduated bar, a disk carried thereby, having asight-opening, the sizeof which is adapted` to be varied, a slide-plate adjustably secured on said bar, and provided with an alining opening, and means for varying the size and proportion of the opening in the slideplate. v

7. A photographic view-meter .comprising a bar, a sight-disk located at one endof the bar, a slide-support adjustable onv the other end ofthe bar, having an opening and a slide adjustable in the opening of theslide-support. y

In testimony whereof I affix my signature in presence of two witnesses.
