CHARLES EDWIN SHARLOW, 0]? UNION HILL, NEW JERSEY. i
FILM-REEL FOR MOVING-PICTURE MACHINES.
Application filed June 5, 1913.
struction and arrangement of parts described and claimed, a distinctive feature being, the filnr clasp, consisting of a tubular central portion fitting in a corresponding recess in the hub and formed with lateral wings or extensions which conform to the periphery of the hub and are adapted to perform the function of film end holders, as hereinafter more fully set forth.
In the accompanying drawings. Figure l, is a side elevation of the reel; and Fig. 2., an edge view thereof. Fig. 3, is an elevation of either end of the hub, the side disks being omitted; Fig. 4, is an elevation taken at right angles to Fig. 3; Fig. 5, is an elevation looking in the direction of the arrow, Fig. 3; Fig. 6, a section taken. upon plane of line 6-6 Fig. 5; Fig. 7, a section taken upon plane of line 7-7 Fig. 5; Fig. 8, an isometrical View of the film clasp; Fig. 9, is a detail view showing a modification in the construction of the reel hub.
The hub A, may be made of wood or other fibrous material, formed with an axial metallic key bushing a, and with counter-sinks a, a, for the heads of the screws by which the disks d, d, are secured to the hub.
The novelty in the construction of the hub in the present case consists in forming it with the socket 8, pa allel to its axis, for the reception of the spine 7), of the film clasp B. The socket 8, includes the slot s through. which the contracted portion of the spine Z), protrudes, and on either side of which the film-holding wings Z1 6 extend laterally.
The film clasp B is preferably although not necessarily made of elastic resilient material bent in to the requisite shape. Thus Specification of Letters Patent.
The invention consists in the specific con- Patented Nov. 24, 1914.
Serial No. 771,788.
a blank of sheet metal may be used for the purpose. The enlarged portion of the spine is preferably cylindrical, to fit a cylindrical bore 8, in the hub A, although obviously other forms in cross section of both socket and spine may be resorted to .---without dcparting from the spirit and intent of my invention in this respect, the -.=.-.--ential feature being a spine with a main portion 72, of
greater width than the slot portion 8, of the ,a
socket s, so that the spine can only be inserted or witlulrawn longitmlinally as related to its socket,the slot portion 8, 01 the socket serving mainly for the accommodation of the contracted portion of the spine. The width of the slot a, may however be made sullicient to admit of the utilination of the elasticity and resilience of the spine in inserting the end of a film between the peripheral surface of the hub A, and j one of the clamping members I), and holding it in such position, or releasing it therefrom, asrequired. Furthermore the end of the film may be inserted into the spine itself if preferred, the contracted portion ol the spine acting as spring jawsto retain the same, so that I practically, by my specific construction, atl ord three means of film attachment, 2'. inserting between the lips of the spine, or beneath either of the 1 clasp leaves b 7). Thus it is not necessary ever to turn the reel around in order to attach thefilm in proper relation thereto, am a third and convenient method of attachment is ail'orded by the contracted portion of the spine acting as spring jaws as before stated. Furthermore the clasp members I), b, conform snugly totlle periphery of the hub, so as to afford a close and symmetrical wind and unwind of the film, thereby obviating undue wear thereof.
,.-In lieu of a solid. wooden hub hereinbetore described a metallic hub may be sub stituted as in Letters Patent No. 971,317, in
which case the socket s, s, will be formed said socket and insertible in the socket longitudinally only with relation'to said slot said clasp having a filmholding Wing concentric With the hub.
52. la a reel of the character designated,
hub having a socket and slot parallel to its axis formed therein, and a film clasp formed with a spine fitting in said socket and having a contracted portion protruding through said slot, said clasp insertible only length- Wise of the hub being also formed with film-holding members extending laterally Lon either side of said spine and overlapping the periphery of the hub for the purpose described.
8. In a reel of the character designated, a hub having a cylindrical and slotted socket .parallel to its axis formed therein, and a film clasp formed with a spine consisting of acylindrical portion and contracted portion fitting in said slotted cylindrical socket, said filill'dilsl) insertihle only lengthwise of the hub being also formed with filmliolding members extending laterally on either side of the spine and over-lapping the periphery of the hub for the purpose described.
4:. In a reel of the character designated, a;
clasp and the bearing of: its contracted por-' tions against the walls of the slot serving to hold the film-holding members snugly against the periphery of the hub.
