D I SPLAY ALBUM Filed Sept. 10, 1965 United States Patent 3,344,794 DISPLAY ALBUM Robert W. MacWilliams, Winchester, Mass., assignor to Samuel Ward Manufacturing Co., Inc., Boston, Mass., a corporation of Massachusetts Filed Sept. 10, 1965, Ser. No. 486,491 1 Claim. (Cl. 12920) This invention relates to display albums having pages with transparent protective coverings.
The primary object of the invention is to provide a display album with pages covered by transparent protective sheets in such a manner as to allow easy and full access to the page surfaces without disassembling pages and without injuring or disturbing items displayed.
The invention features an album in which the leaves are retained therein along one edge and are each covered by a transparent protective sheet retained in the album along an edge adjacent the retained leaf edge, bent around the edge of the leaf opposite the retained leaf edge, and free along the edge of the sheet opposite the retained sheet edge.
Other objects, features and advantages will appear from the following description of a preferred embodiment of the invention, taken together with the attached drawings thereof, in which:
FIG. 1 is a perspective view of the album; and
FIG. 2 is a broken away perspective view, partially in section, of a portion of the album, showing in detail the leaf and protector construction.
Referring to the drawings, the album has a pair of covers 14, 14a and a leaf unit 24. Each cover is a relatively thin inner rectangular cardboard sheet 16 superimposed upon a relatively thick outer rectangular cardboard sheet 18, sheets 16 and 18 being joined along three edges by exterior paper casing 20 but open along one longitudinal edge to provide access to flap receiving pocket connector 22.
Leaf unit 24 comprises a multiplicity of leaflets 26 stitched together by thread 27 and bound in the usual manner with external backing strip 25. Each leaflet has two paper leaves 28 coated on both surfaces with heavy water soluble adhesive, spaced at their bound edges 29 and joined there by nylon tape strip 30 (sold as Y-9176 White cloth shoe tape by Minnesota Mining & Mfg. Co.), and two transparent cellulose acetate protectors 32 similarly spaced and joined at their bound edges by tape strip 34 (also Y-9176). Each protector 32 is a .003 thick sheet about twice the area of a leaf 28, is bent around the leaf along an edge 35 thereof parallel with the bound edge, and includes a free edge 37. The free edge 37 are adjacent the outermost leaf surfaces of each leaflet, so that for the page unit as a whole, the protectors 32 bend around adjacent leaves in opposite directions. Strips 30, 34 stick to each other where exposed between the leaf and protector edges. In the outermost leaflets the outermost page 28 and protector 32 are replaced by a cardboard flap connector 36 thus secured between tape strips 30, 34 and extending about one third the width of a leaf.
The album is assembled by inserting the flap connectors 36 of the leaf unit into the pocket connectors of the covers 14, 14a. Full access to the leaf surfaces is easily accomplished without leaf disassembly by grasping free edge 37 of the protector, and lifting it over leaf edge 35. The protector is similarly returned to its protective position by passing edge 37 over leaf edge 35 in the opposite direction.
Other embodiments will occur to those skilled in the art and are within the following claims:
A display album comprising a multiplicity of leaflets, each of said leaflets consisting of a first leaf coated on both surfaces with adhesive,
a second leaf coated on both surfaces with adhesive,
a first transparent protector,
a second transparent protector,
a leaf strip binding tape, and
a protector strip binding tape,
each said leaf including an inner edge and an outer edge,
each said protector including an inner bindin edge, a second inner edge, and a fold edge,
the inner said binding tapes being bent into a crosssection of U-shape when the leaflet is in closed position,
said protectors being adhesively secured respectively along said binding edges to the sides of said protector tape,
the outer of said binding tapes being bent into a cross-section of U-shape including therebetween said inner edges of each said leaf and said inner binding edges of each said protector when the leaflet is in closed position,
the leaves being adhesively secured to said leaf binding tape along said inner edges of said leaves,
said fold edges of said protectors being adpacent respectively to outer edges of said leaves,
said second inner edges of said protectors being free,
said leaf inner edges being spaced apart when said leaflet is in open position,
said protector inner binding edges being spaced apart when said leaflet is in open position,
each said leaf tape adhering to a said protector tape over an area between the spaced apart leaves and protectors,
said leaflets when closed being in side-by-side relation,
with outer U-shaped binding tapes abutting, and said leaflets being anchored in said album by stitches extending through said area.
