SPECIFICATION forming part of Letters Patent No.. 662,998, dated :December 4, 1900.
Application filed August 19, 1899. Serial No. 727,858. lNo model.)
T0 @ZZ whom t may concern:
Be it known that we, JOHN STRATTON VRIGHT, residing at Duxbury, in the county of Plymouth, and CHARLES S. GOODING, residing at Brookline, in the county of Norfolk, State of Massachusetts, citizens of the United States, have invented new and useful lmprovements in Cameras, of which the following is a specification.
The object ot" this invention isy to produce a camera Which shall be compact and durable in construction and convenient, simple, and rapid in the operation of its working parts.
Our improved camera comprises in its construction, first, a magazine for cut plates or iilms, substantially the same as that described and illustrated in a separate application,SerialNo.728,026,tiledAugust21,1999; second, a focal-plane shutter, substantially the same as that described in another application, Serial No. 728,025,1iled August 21,1899; third, a lens and mechanism for adjusting the same, and, fourth, a reiiectingmirror and finder,with a cover for said finder and connected mechanism for automatically operating` in correct timesaid magazine, shutter, reflecting-mirror, and cover.
The invention consists in mechanism for operating the reliecting-mirror and the cover for the finder.
The invention further consists in mechanism for automatically operating in correct time with relation to each other the shutter and magazine.
The invention still Jfurther consists in mechanism for automatically operating in correct time with relation to each other the shutter and magazine, reiecting-mirror, and the cover for finder.
Referring to the drawings, Figure 1 is a side elevation of our improved camera, partly broken away in section and with the side cover of the case removed. Fig. 2 is a vertical section taken on line 2 2, Fig. 1. Fig. 3
l is a plan view of a portion of our camera,
partly broken away and shown in section, as on line 3 3. Fig. 4E is a vertical sectional elevation, line el 4E, as viewed from the right of Fig. 1. Fig. 5 is a perspective view of the cut-plate-carrier slide broken away to save l space.
Fig. G is a detail side and front elevation of the arm to which the mirror is at tached. Fig. 7 is a detail section, line 7 7, Fig. 1. Fig. Sis a verticalcentrallongitudinal section.
Like letters and numerals refer to like parts throughout the several views of the drawings.
In the drawings, 1 is the casing or box of the magazine torcut plates or films.
2 is the chamber containing the unexposed cut plates, and 4t is the chamber into which the unexposed cut plates are carried by the mechanism hereinafter described. The chamber 2 is separated from the chamber d by a fixed partition 5.. The bottom wall 6 of said chambers 2 and l is removable and is fast to a removable cap 7. A sliding partition 14C is kept pressed against the unexposed cut plates in the chamber 2 by a series of iiat springs 15, fastened alternately to the fixed partition 5 and the sliding partition 14 at the center of said springs by screws 16.
The upper edges of the cut plates in the chamber 2 are guided by a fixed horizontal partition 17, which extends from side to side of the casing 1. In the front of the cut-plate holder is a rectangular opening 18, said opening being about one-fourth inch shorter on each side than the cut plates. A slide 19 is inserted through a groove 2O in the side of the casing 1 to cut off the light from the cutplate chamber in the usual manner. The casing 1 is grooved at 2l 21 to receive the sliding pieces 22, said sliding pieces being joined together by the cross-piece 23.
entire length thereof to a depth equal to the thickness of one of the cut plates. The side pieces 22 and cross-piece 23 are rigidly connected together and form, as a whole, the cutplate-carrier slide A.
The springs 15 force the cut-plates forward toward the opening 1S, the bottom side of the foremost cut plate resting against the crosspiece 23 in the groove 24, the two sides of said cut plate being pressed against the strips 25 25, and the top side being pressed against the strip 26, said strips and cross-piece forming the four sides of the opening 1S. By raising the cross-piece 23, as hereinafter described,
The cross-piece 23 is grooved at 24 throughout the IOO the cut plate nearest the opening 1S (after l being exposed) will be pushed up through the slot 27 until itis caught between the rubber-covered rolls 2S.
The rolls 23 are geared together by pinions 29 30, said pinions 29 being rotated by gears 3l, fast to a shaft 32. The shaft 32 and shafts 33 34- have bearings in plates 35 on each side of the casing l. Upon the outside of the casing l is a gear 36, fast tothe shaft 32, by means of which said shaft and the other gearing fast thereto is rotated. The gear 36 is rotated by mechanism hereinafter described.
Upon each side of the casing l, on the inner side thereof and fast to the shaft 32, is a pair of gears 37. Each of said gears 37 meshes a gear 33. The gears 33 turn upon studs 39, riveted to the plates 35, and have riveted to the face thereof a finger -l-O, which engages a notch 41 in the sliding pieces 22 22. The casing lis recessed at -i-2 to receive the wire spring 3, said spring being fast at it to the casing l and bearing at its free end upon a pin 45, fast to the sliding piece 22.
The operation of the mechanism whereby the exposed cut plate in the chamber 2 is carried over into the chamber at is as follows: The gear 36 being turned in the direction of the arrow b, the other gearing will rotate in the directions indicated by the arrows, Fig. l. The iingers 40 will be moved upwardly, raising the sliding pieces 22 22 and crosspiece 23, pushing the film, which rests upon the groove 24, up through the slot 27 until its upper edge engages the rolls 23, when the cnt plates will be carried forward to the second pair of rolls, being guided thereto by the curved guides e6 and thence to the next pair of rolls and finally through the opening 1&7 into the chamber 4, light springs 4:8 guiding the cut plates as they enter said chamber i and holding them against the partition 5. After the top edge of the cut film has been taken by the first pair of rolls the ends of the lingers L LO clear the sliding pieces 22 and allow them, together with the cross-piece 23, to be brought back to the position shown in the drawings by the action of the spring 43.
Itis evident that the mechanism for imparting the herein-described reciprocating motion to the cut-plate-carrier slide may be varied without departing from the spirit of our invention.
rlhe gear 36 is rotated by an intermediate gear 50, which rotates upon a stud 5l, fast to the plate 52, said plate being fastened to the casing 53 of the camera. The intermediate gear 5() is rotated by a gear 5st-, which turns upon a stud 55, fast to a plate 56, fast to the casing 53 of the camera. The gear 54c is connected by a sleeve 57 to a hand-wheel 53, by means of which said gear 51)c and the train of gearing hereinbefore described are rotated.
59 59 are wooden rolls, to which is attached the curtain GO. Each of said rolls is attached to a tube 6l, having a flange S2 thereon. The tubes (il lil are connected together by twol wires G3 G4, each wire fastened to said tubes in suoli a manner that when the wire G3 is coiled several times around the lower tube Gl the other end of said wire G3 will be nearly uncoiled from the upper tube (il, whereas the wire 64 will at the same time be coiled several times around the upper tube Gl. and nearly uncoiled from the lower tube Gl, and vice versa. To the wire (53 is fastened a block 65, with pins GG 66 thereon. Said pins engage slots 67 07 in the forked piece 63, said forked piece forming a part of a spring-lever (59, in which the spring-wire 70 is fastened to said forked piece 68 and passes through a hole in the rocking pin 7l. Said pin rocks in bearings in the bracket 72, fast to the case 53. The bracket 72 is formed of two plates 73 7-1-, fastened together by studs 75. The springwire 70 is held at the end opposite to the forked piece 68 by hooks 7G, fast to a mental plate 77, fast to the casing t will be seen that by placing the springwire in different hooks on the upper side of the center line a a, Fig. l, the tension npon the spring may be Varied and the block 65 forced down against the stop 73, fast to the casing 53, as in the drawings.
lf it is desired to set the curtain to move downwardly, Fig. l, the wire 70 is carried over at its right-hand end, Fig. l, to the lower side of the center line d c and hooked into one of the hooks 76 on the lower side of said line a a. This will bend the spring 70 and cause it to press upwardly upon the block (35.
The block 65, wires 63 and ttl, and the parts connected thereto are locked in position by blocks 79 and 30, fast to the wire 63. The block G9 is shown locking said partsI in the drawings, said block being located between two ears Sl 3l on the locking-plate 32, said plate being fastened to the casing 53.
The block 79 is thrown out from between the ears 3l and the spring-lever 69 allowed to act by a lever S3, pivoted at Si to two ears S5 35 upon the locking-plate 32. The righthand end of said lever, Fig. 2, is depressed at the proper time by the cam-shaped projection S6 upon the rear face of the gear 5i, thus raising the left-hand end of said lever, Fig. l, and throwing the block 79 out from between the ears Sl, and the spring-lever (39 then throws the block (35 and wire (.53 upward until the block 79 strikes the stop 37, when the block SO will be opposite the space between the ears 8l, and the lever S3 having been drawn down by the spring SS the block 8O will drop in between the ears 3l., locking the wire G3 and its connecting` parts.
In order to graduate the speed of the curtain for instantaneous work, we provide a pneumatic cylinder, pivoted at 90 to a plate 91, fast to the casing 53, and having a doubleacting piston therein fast to a piston-rod. Said piston-rod 92 is pivotally connected to a forked arm 93, said arm passing through a hole in the rocking pin 7l and being clamped thereto bya set-nut fl-t. The arm 93 has gradlOO TIO
'nations 95 thereon, so that the arm 93 may be set at different points with relation to the center of the rocking pin 71, and thus the distance through which the end of the arm 93 moves may be varied, and hence the travel of the piston and piston-rod in the cylinder 89 will be varied, compressing the air more or less and varying the speed at which the curtain is carried by the springlever 6.() through the intermediate connections hereinbefore explained.
The curtain has a slot therein, the width of which may be varied, as described in an application hereinbefore referred to on Focal-plane sh utters,7 or in any ofthe methods now in use for accomplishing the same result.
The camera herein described may also be arranged to take pictures by time exposure in the same manner as described in said application 't'or Focal-plane shutters. The lens 96 is fast to a frame 97, arranged to slide inthe casing 53 and having a rack 0S fast thereto, meshing a pinion 99, fast to a shaft 100,having bearings 101 in the casing 53 and in the side-cover 102 of said casing. The shaft 100 is rotated by the hand-wheel 103, fast thereto, all in a manner well known to those skilled in the art and forming n.0 part of this invention. In the upper side of the casing 53, Fig. 1,. we provide a ground-glass inder7 104, upon which is thrown a reflection of the picture by a mirror 105. An opening 106 in the casing 53 above the finder 104 is closed by a cover 107, pivoted at 10S on each side of the casing 53 to plates 109, fast to said casing. r1`wo arms 110, one on each side of the cover 107, are connected by links 111 to arms 112, fast to a roclcshaft 113. The arms 112 each have a projection 114 thereon, to which is fastened the mirror 105. On the outside of the casing 53 is an arm 115, fast to said rock-shaft 113 and bearing against an open cam-plate 116, fast to the cam-gear 54. To prevent the' cover 107 from passing beyond a right angle, Fig. 1, we provide a stop 117, against which the arm 110 strikes when the cover 107 is open at right angles, the mirror 105 at the same time resting on stops 118, lfast to the sides ot' the casing 53. A spiral spring 110 serves to draw the mirror 105 down and to hold the arm 115 against the cam 116.
The operation of the mechanism hereinbefore described as a whole is as follows: The parts being in the position shown in Fig. 1, the right-hand end ot' the spring 70 is carried over to the lower side of the center line a a and hooked under one of the hooks 76 on the lower side of said line a a. The lens 96 is then adjusted by turning thchandwheel103 until the reflection upon the finder 104 is in focus. The hand-wheel 18 is then rotated, turning the camplate 116, raising the arm 115, and rotating the rock-shaft 113 to an eX: tent sufficient to raise the mirror 105 and lower the cover 107 to a horizontal position through the arm 112, link 111, and arm 110. As soon as the mirror 105 is raised out of the path of rays o1' light from the lens 96 and the cover 107 is closed over the opening` 106 the cam 86 strikes the right-hand end of the lever 83, depressing said lever at the right and elevating` itat the left of the pivot S4, thus lifting` the block 79 from between the ears 31, releasing the springlever 69, which carries the block upward with the wire 63 and other parts connected thereto until the block 79 strikes the stop S7, and the block S0 being then opposite the space between the ears S1 will drop in betweeen said ears. It is evident that as the wire 63 moves up as described the curtain 60, with the slot therein, will move down across the face of the sensitized cut plate, which rests, as heretofore described, against the carrier-slide A. As soon as the curtain 60 has completed its motion, as described, a further rotation of the hand-wheel 53 willbring the arms 60 into connection with the notches 41 in the sides 22 of the carrier slide A, through the rotation of the gears 54 50 36, shaft 32, gears 37, fast to 32, and gears 33, meshing said gears 37. The exposed plate will then be carried up out of the chamber 2 and over into the chamber 4, as hereinbeforc described. After the plate is removed from the chamber and as soon as the gear 54 has made one complete rotation the parts will assume the relative positions shown in Fig. 1, the cover 107 assuming a Vertical position and the mirror a position at forty-live degrees, as shown.
lt will be evident from the foregoing descr'ption that it would be impossible for a iilm or plate to be exposed twice. It will also be understood that-only three motions are necessary in taking a picture-namely, first, setting the spring-lever 69; second, `focussing the picture, and, third, rotating the hand-wheel 5S once.
