TUNITED STATES '1 JOHN H. BRUIBAKER, or GRAND RAPIDS, MICHIGAN.
DEVICE EMPLOYED IN FINISHING AND RETOUCHING PHOTOGRAPHIC NEGATIVES AND THE LIKE.
Application filed February 13, 1922. Serial No. 536,044.
To aZZ whom it may concern:-
l' Be it known that I, JOHN H. Bnnnaxnn, a
citizen of the United States, residing'at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Devices Employed in Finishing and Retouching Photographic Negatives and the like, of which the follow ing is a specification.
The present lnvention relates to dev ces employed in finishing or retouching photographic negatives and thelike; and its ob jectis to provide a structure or device of that character which may be readily operated and adjusted to varying conditions inpractice, and wherebythe light may be mostadvantageously thrown upon anddirec ted to the work.
This object is attained by, and the invention finds preferable embodiment in, the
structure or device hereinafter particularly described in the body of this specification and illustrated by the accompanying drawings, in which i 'Figure 1 is 'a' sectional view of a device employed in finishing or retouching photographic negatives and the, like, taken on a vertical plane corresponding to line 11 of Figures 3 and 1; V
Figure 2 is a side view of the same;
Figure 3 is a rear view thereof;
Figure 4; is a transverse sectional view of the frame and slidable box of said device, taken on a plane corresponding to line 1- 1 of Figure 1;
Figure 5 is an enlarged sectional view of portions of the same taken on the same planejand Figure 6 is a side view of a supporting arm for said frame.
In the embodiment of the invention chosen for illustration vby the drawings and for detailed description in the body of this specification, my device has a frame 1 containing a translucent and preferably also transparent (i. e. clear) pane 2 of glass, upon 4 whose outer side the photographic negative or the like is laid while being finished or retouched. 'rear side of this frame slidably upwardlydownwardly in spaced slide hearings or guides 1. This box has a light-reflecting inner surface 5, preferably white (and pref erably the entire inner surface of this box A box 3 is mounted on the I is white) and inclined, as shown in Figure 1, relat1vely to the direction in which the box.
slides in its bearings. This box contains a lamp 6 and has an opening 7 toward the frame, containing a pane 8 which is translucent but preferably non-transparent beingdesirably a sheet of ground glass. v These two panes 2 and 8 are preferably spaced apart parallelly as seen in Figures 1 and 4, for I have found that the light pass ing through a translucent but non-transparent pane, as of ground glass, and through a spaced away pane of clear or transparent glass is peculiarly effective in finishing orretouching photographic negatives and the like. i
This pane 8 is held securely in position between the spaced strips 9, 10 of the box ex tending transversely to the direction of the boxs sliding movement (which strips engage the upper and loweredges of said pane) and between the slide bearings 4, 1
Y which engage the side edges of said pane.
As shown in Figure 1, the light fromthe lamp 6 is reflected by the boxs inclined in ner surface 5 to and through the panes 8, 2 and through the workthe negative or the likelying on the front or face of the pane 2; and it will be seen that, as the box is slid upwardly or downwardly the light may be made to shine directly through an upper or lower part of the pane 2 as may be desired, thus to illuminate particularly a higher or lower portion ofthe work.
To accommodate the frame 1 to the angle desired by the operator, it is hinged or swingablymounted at 11 on a suitable base 12; The supporting arms 13 hinged to the frame at 1 1 maybe held in desired adjustment by passing pins 15 through their openings 16 and'into any one of the openings 17 in the base. To secure the box in a desired position in itsslide bearings, the binding screw 18, threaded in one of the ribs 19 in which are formed the slide bearingst, and adapted to engage the side of the box, may be screwed down into such engaging or binding position.
It will be seen that the opaque strip 9 prevents the light from the lamp from shining directly on the pane 2 (or that portion of it on which the work is laid) and that all the light reaching said pane (or its said portion) is reflected from the inclined surface or reflector 5 and passes through the trnslucent but non-transparent pane 8 whereby the light is diffused.
The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hereinbefore described.
I claim:
1. In a structure of the character and for the purpose described; a frame containing an outer transparent pane and carrying an inner translucent non-transparent pane spaced from said transparent pane.
In a structure of the character and for the purpose described; a frame containing .a translucent pane a box slidably mounted on the rear of the frame, and having a lightreflecting inner surface inclined relatively to the direction of the boxs sliding movement and an opening vtoward the frame; a lamp inside the box.
37 In a structure of the character and for the purpose described; a frame containing a transparent pane; a box slidably mounted on the rear of the frame, and having a light-reflecting inner surface inclined relatively to the direction of the .boxs sliding movement and an opening toward the frame containing a translucent non-transparentpane; a lamp inside the box.
4. In a structure of the character and for the purpose described; a frame containing a transparent pane, and having spaced slide hearings on its rear side; a box slidable in said bearings and having a lightreflecting inner surface inclined relativelv to the direction of the boxs sliding movement, and spaced strips adjacent the frame tively to the direction of the 'boxs sliding movement and an opening toward the frame containing a translucent non-transparent pane spaced from the frames said pane; a lamp inside the box; means for holding the box in slid posit-ion; means for holding the frame in swung position.
6. In a structure of the character and for the purpose described; a frame carrying a translucent non-transparent pane; a lamp; an opaque body between the lamp and the pane to prevent light from the lamp shining directly on the pane; a reflector inclined at an angle in the plane which is perpendicular to the face ofthe vpane adapted to reflect the light from the lamp on the pane.
In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan,
this 10th day of February, 1922.
JOHN BR'UBAK'ER.
