i mnovmmmr m CAMERA-SCREENS.

Thn Bahodule refer-'rad to in these Letton Patent and making part ofthe lmo.

'To all whom it may concern:

Be is known man1, Efrmomf, of Lanisvme, in-

the county of J eeison, and State of Kentucky, have invented a new and improved Camera-Screen; and I do hereby declare that the following is a full, clear, and exact description thereof, which willenableothers skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification. i This invention relates to screens for cameras, and consists in the combination andanangement of parts, as hereinafter specified. f

Figure 1 represents a part 'of the camera-tube in dotted lines, with my improved screen attachedand Figure 2 represents a plan of the screen-attachment. Similar letters of reference indicate corresponding parts. v y

A is a circular screen, of cloth or other suitable substance, stretched over a wire, B, connected to thev spindie C, which is 'supportedon journals attached to a block of wood, D, or it may be the wall ofthe camerabox., The said spindle is provided with a coiled spring. E, which is arranged to hold the screen down in.- the position represented in ligd.

One end of the spindle C has aA slotted arm, F, in which a pin, G, of a Sliding thumb-bit, H, takes, for the purpose of throwing the' screenup by pressing the thumb-hit inward. This slot terminates atthe outer end of the arm in a slightprecess, 1,' in the wall of the slot opposite 'the thumb-bit, into lWhich'the pin G will fallwhen the screen' is raised, andl lock it in the raised position, the said' recess preventing the 'pin Afrom sliding back toward l the other end of the slo'tunder the pressure ofthe spring E.

' This screen is' fastened onthe inside of the camera-' box, just above theinner end of theA tubeeither to.

'the wall of 'the box,or to the bloelrl., which -is'suitably fastened-thereto, so that the thumb-hit H L only projects outside, whereby the operator, when adj ust-l ing theplate, may, by pressing on the button L with the finger', raise the screen, and secure it in the elevated position, and by a slight touch on the inside' of the button, withthg back of. the foreflnger, allow it to spring down. f`

This improved screen may be operated without attracting the attention of the sitter, as the common cloth screens do, and is particularly useful `when the subjects are small children, who may be caught at a happy moment, and much of the stiffness non' seen in the pictures of children mayr be avoided.

Hairing thus described my invention, i

I claim as new, and, desire to secure by Letters Patent- The. combination, withthe screen A, arranged in the camera-box, as described, and provided with the -coiled springs E, of the .thumb-bit H L, pin G, and slotted arm, constituting the raising and locking-de;

vice, alls'ubstantially as specied.
