SLIDE HOLDER.

Application filed July is,

This invention has reference to a holder for filing glass slides, such as are used by microscopists for the preservation of mounted specimens, sections, smears, etc., the device being also designed'for use as a file for photographic negatives, lantern slides, or other flat articles whose surfaces are de-: signed to be protected from scratches, stick ing together, etc.

The object of the invention is the provision of a device for this purpose which can be cheaply constructed and which will effectively sustain the slides or mounted speelmens therein.

To the attainment of the above broadly stated objects and others which will present themselves as the nature of the invention is better understood, the improvement further resides in certain novel features of construction, combination and operative association of parts, a satisfactory embodiment of which is disclosed by the accompanying drawings.

In the drawings:

Figure 1 is an elevation of my improve ment.

Figure 2 is a sectional view on thev line 2-2 of Figure 1.

Figure 3 is a fragmentary perspective View to show the manner in which the holders with the specimens therein may be arranged in a filing case.

In carrying out my invention 1 employ'a flat sheet 1. This sheet is preferably of metal but may be formed of card board or any other material suitable for the purpose. The lower edge of the plate is flanged, as at 2, and the body of the plate, at spaced intervals,is slotted longitudinally and transversely and the metal bounded by these slits-is bent outwardly to provide ways 3. These ways are arranged in spaced pairs and between each pair of ways there is designed to be received a glass slide, photographic negative or anyother plate 4 having specimens, sections, neg-. ative or other surfaces which it is' desired to preserve and prevent scratching or sticking together. It is to be .notedthat the flanges 3 1926. Serial N0.'122,956.

that provide the ways terminate a suitable distance above the edge of the plate 1, and the upper edge of the said plate 1, between each .from sliding through the ways oif of the body 1, regardless of the position which the body is caused to assume.

As disclosed in Figure 3 of the drawings, the body sheets 1 are of a size to be snugly received in the drawer of a filing cabinet and the simplicity of my construction and the advantages thereof will, it is believed, be

perfectly apparent to those skilled in the art to which such invention relates so that a further detailed description is not thought required. I Having described the invention, I claim A slideholder of the character described comprising a sheet metal plate having spaced I pairs of outstruck guldeways thereon ar-. ,ranged' in parallel relation, each pair of guideways being adapted to have a fiat article slida-bly engaged therein, one edge of the plate at the ends of all the'guideways being formed with an outstanding continuous stop flange adapted for engagement by the fiat articles for limiting the movement thereof, the opposite edge portion of the plate being slit at intervals to form tab-like-extensions opposite the spaces between the pairs of guideways, the extensions being bent somewhat out of the plane, of the major portion ofthe sheet and engageable with the rear sides of the flat articles for urging them against the overhanging portions of the guideways and thereby preventing looseness,

the ends of said extensions being notched out for the accommodation of the operators fingers whereby they mayconveniently grasp the end of the flat article within each.

pair of guideways, H Y

In testimony whereof I aiiix my signature.
