Abstract
Abstract A slide orienting device for orienting slide transparencies comprising a rotatably mounted slide support bracket configured to support a slide transparency and a fixed slide retainer means which cooperatively engage the slide transparency in axial alignment with the lens and light source of the slide projection. The device further includes a rotation means to rotate the slide support bracket relative to the slide projector to selectively orient the slide and a plurality of slots formed about the periphery of the support bracket to unload the slide transparencies notwithstanding the support bracket orientation.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
123 words
A slide orienting device of the type primarily used with a slide projector, said device comprising: a movably mounted slide support bracket means, a slide retainer means, said slide retainer means and said slide support bracket means cooperatively engaging a slide transparency in viewing alignment with the lens and light source of the slide projector, said slide support bracket means including an aperture formed therein and configured to cooperatively engage in supporting relation thereto at least a portion of the slide transparency such that said transparency is properly oriented for viewing; orienting means to move said slide support bracket means relative to the slide projector to selectively orient the slide transparency, and removal means disposed to remove the slide transparency from said device.
Claim 2
Dependent Claim
123 words
A slide orienting device of the type primarily used with a slide projector, said device comprising: a movably mounted slide support bracket means, a slide retainer means, said slide retainer means and said slide support bracket means cooperatively engaging a slide transparency in viewing alignment with the lens and light source of the slide projector, said slide support bracket means including an aperture formed therein and configured to cooperatively engage in supporting relation thereto at least a portion of the slide transparency such that said transparency is properly oriented for viewing; orienting means to move said slide support bracket means relative to the slide projector to selectively orient the slide transparency, and removal means disposed to remove the slide transparency from said device.
Claim 3
Dependent Claim
65 words
The slide orienting device as in claim 1 wherein said removal means includes a plurality of spaced rejecting passages extending from the outer periphery of said slide support bracket means inwardly to said aperture, whereby the rejecting means of the slide projector may operatively pass into the rejecting passageway to engage at least a portion of the slide transparency to force it from the device.
Claim 4
Dependent Claim
28 words
The slide orienting device of claim 2 further including an alignment positioning means cooperatively engaging the slide transparency and maintaining it in vertical alignment with the slide projector.
Claim 5
Dependent Claim
60 words
The slide orienting device of claim 3 wherein said alignment positioning means comprises at least two hook-like members fixedly attached to the slide projector and extending forwardly through said aperture of said slide support bracket means, said hook-like members positioned to engage the rear surface of the slide transparency thereby retaining it in predetermined position relative to the slide projector.
Claim 6
Dependent Claim
36 words
The slide orienting device of claim 1 wherein said orienting means comprises a rotation means for rotating the slide transparency and said slide support bracket means relative to the slide projector to reorient the slide transparency.
Claim 7
Dependent Claim
24 words
The slide orienting device of claim 5 wherein said rotation means includes at least one tab formed on said slide support bracket means manually.
Claim 8
Dependent Claim
47 words
The slide orienting device of claim 6 wherein said rotation means further includes at least one detent means and corresponding protrusion formed on the slide projection which cooperatively engage each other to positively indiCate the position of said slide support bracket means relative to the slide projector.
Claim 9
Dependent Claim
48 words
The slide orienting device of claim 1 wherein said aperture comprises a square shape and said slide support bracket means is inclined to the vertical so as to be oriented such that the lower inner side wall of said square aperture is positioned for engagement with said slide.
Claim 10
Dependent Claim
32 words
The slide orienting device of claim 8 wherein said slide retainer means comprises a slide retaining surface positioned to operatively engage the slide transparency thereby retaining the slide in viewing the alignment.
Claim 11
Dependent Claim
66 words
The slide orienting device of claim 9 wherein said slide retaining surface comprises an annular surface formed by the cooperative relationship of a hemispheric recess and hemispheric raised plate formed in said slide and retaining means, said recess and raised plate being disposed on an inclined surface of said slide retainer means, whereby said slide support bracket means and slide retainer means operatively engage each other.
Claim 12
Dependent Claim
28 words
The slide orienting device of claim 9 wherein said slide retainer means further includes a slide passage extending through a portion thereof to communicate with the annular surface.
Claim 13
Dependent Claim
46 words
The slide orienting device of claim 9 wherein the radium of said recess is at least as large as one-half the diagonal of the slide transparency whereby rotation of the slide transparency and said slide support bracket means relative to said slide retaining means is permitted.
