UIED STATES ADA E, BUDGE. E
GRAJLZOPHONE-REUUED Application filed July 16,
To all whom it may concern:
Be it known that I, ADA ELIZABETH Runes, a subject of the King of Great Britain and Ireland, residing at 49 VVellesley Road, Gunnersbury Road, London, W l, England, have invented Improvements in or Relating to Gramophone-Record Envelopes and Cases, of which the following is a specification.
This invention relates to envelopes or containers for gramophonerecords and has for its object a construction of such envelopes which permits the record to be readily inserted and without any auxiliary fastening means to be securely enclosed and retained therein, so it may be carried by a handle or protect the record from accidentally falling out as well as from dust when used for filing in a cabinet, album or the like.
My envelope, according to this invention, consists in two fiat envelopes or lriags, made of paper, cardboard, or other suitable material, arranged one within the other so that the inner one forms a pocket which may be rotated in the outer one. When the open sides of the two envelopes are in unilateral position a record may readily be inserted into or withdrawn from the inner envelope, so that when the latter is rotated about an angle of 180 its closed side closes the open side of the outer envelope, and thereby securely retains the record therein.
The front and back panels or faces of one envelope are pivotally connected to the front and back panels respectively of the other envelope, by means of eyelets or the like arranged in alignment with their axis centrally of the inner envelope and approximately equidistant from the three closed sides as regards the outer envelope, such distance corresponding to at least one half of the diagonal or radial dimensions of the inner envelope.
The outer envelope is of substantially square shape and closed at three sides by gluing, stitching, or. otherwise. The inner envelope is preferably formed with a semicircular bottom part closed at its circumference and an equilateral triangular part the hypothenuse of which coincides with the diameter of the semi-circular part-which is open along its two sides.
Both envelopes may be semi-circular or both parts may be square shaped. In the latter construction, however, the outer en- Lennon, ENGLAND.
ENVELOPE AND CASE.
1923. Serial No. 651,990.
velope is of a size adapted to the diagonal of the inner envelope.
Envelopes intended for filing records in a cabinet, album or the like are preferably provided with windows or transparent members at both the front and back face, formed by circular apertures cut centrally in the panels of both envelopes and covered by celluloid, casein, mica or other transparent material, through which the title label, provided in the centre of each side of the record, may be visible. The pivots for the inner envelope are in this case arranged in the centre of the transparent windows.
If the envelope is intended for carrying therecord, a tape or string handle is fastened to the back of the outer envelope, and if the envelope is intended for filing the records after the manner of a loose leaf binder or the like, it is provided with perforations fitting over the bolts or the like of the binder. These perforations are so located that they are out of centre along the back of the envelope and may thus be threaded on the bolts or rods of a cabinet, album or the like in a manner that alternate envelopes are in staggered positions so that the projecting pivot eyelets shall not be in alignment on the file.
The accompanying drawings show exan'rplos of such envelopes embodying my in vention.
Figs. 1 and 2 show in the open and in the closed positionrespectively an envelope of the simplest form adapted as a record carrier.
Fig. 3 is a section along line 3--3 of Fig. 2, and
Fig. 4 an enlarged section of an eyelet constituting a pivot.
Figs. 5 and 6 show a form of envelope suitable for filing purposes in the open and in the closed position respectively, while Fig. 7 is a section along line 77 of Fig. 5.
In Figs. 1 to i the rectangular outer envelope a is made in the form of an ordinary paper bag by folding at a gluing at the edges a and leaving open at the edge a The inner envelope is formed by two substantially circular panels 6 of a diameter slightly exceeding the diameter of the rec- 0rd r and preferably having two segments cut off along the chords 5 each extending over anangle short of 90 and intersecting each other approximately at right angles, so that the circular edge extends over somewhat more than 180. The two panels are connected along the circular edge by stitching 6 or in any suitable manner. The front and rear panels of the inner envelope are each pivotally mounted on the front and rear panel respectively of the outer envelope at at a point centrally between the edges a and at distance from the edge a slightly in excess of the radius of the inner envelope, by means of an eyelet upon which the two envelopes are adapted to revolve one in relation to the other. The envelopes may be strengthened at the point of their connection by means of washers (Fig. 4) or paper or cardboard lining. Near the closed edge a of the outer envelope, eyelets e are fixed for attaching a tape or string handle Marks 9 and provided on the outer and inner envelopes respectively show by registering when the inner bag has been turned into its proper position for securely holding the record.
Figs. 5 to 7 show a form of envelope more particularly suitable for use in filing cabinets, albums or the like. In order to better withstand wear this form of envelope is preferably made of thin but strong card board. The outer envelope h is stitched along three edges as shown. Both the outer envelope 7L and the inner envelope 2' are provided centrally in their panels with circular apertures 71: which are covered by celluloid, or other transparent material forming windows, and of a size to allow the title label of the record to bevisible. In other respects the envelope is similar to that hereinbefore described in connection with Figs. 1 to 4, the pivotal-points 0 here coinciding with the centres or" the windows is. Near the rear edge two perforations ]L2 are arranged for filing purposes. Having regard however to the projecting eyelets it is desirable that the envelopes should be filed in staggered positions. For this purpose the perforations h are arranged at unequal distances from the centre of the rear edge if so that when the envelopes are alternately reversed the desired object is attained.
I claim 1. An envelope for gramophone records characterized by two envelopes arranged to rotate one in the other so that, when the open sides of the two envelopes are in uni lateral position a record may readily be inserted into or withdrawn from the inner envelope, while by rotating the latter about an angle of 180 its closed side closes the open side of the outer envelope and thereby securely locks and retains a record therein, without other fastening means.
2. In an envelope for gramophone records as claimed. in claim 1, the arrangement whereby the front and back panels of one envelope are pivotally mounted on the front and back panels respectively of the other envelope.
3. In an envelope for gramophone records as claimed in claim 1 the arrangement of transparent members or windows around the axis of rotation in alignment with the title label of the records.
l. In an envelope for gramophone records as claimed in claim 1, the arrangement of perforations adapted to serve for the attachment of a handle or for threading the envelope on the rod, or the like member of a filing means.
5. Envelopes for gramophone records, characterized by two envelopes arranged to rotate one within the other so that when the open sides of the two envelopes are unilateral a record may be inserted or withdrawn from the inner envelope, while by rotating the inner envelope it closes the outer envelope and securely retains the record therein.
6. An envelope for gramophone records, consisting essentially of envelopes arranged to rotate one within the other so that when the open sides of the envelopes are in unilateral position a record may be inserted in the inner one, while by-rotating the latter the outer one is closed, the front and back of one envelope beingpivotally mounted on the front and back of the other. a
7. In an envelope for gramophone records, a pair of envelopes rotating one within the other, means whereby the front and back panels of one envelope are pivotally mounted on the front and back panels of the other, all arranged so that records may be inserted within the envelope and securely retained therein by the action of the closed side of the inner envelope against the open side of the outer envelope, substantially as de- (l.
