REEL AND SPINLLE MOUNT THEREFOR.

Application filed March 8, 1923. Serial No. 623.689.

To all whom it may concern:

Be it known that I, ALBERT S. HOWELL, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful improvement in Heels and Spindle Mounts 'lhcrefor, of which the following isa full, clear, concise, and exact description, reference being had to the accompanying drawing, formii'ig a part of the specification.

My invention has particular relation to reel and spindle mounts of the type usually employed on motion picture machines although not limited to this use alone.

One feature of the invention relates to a simple and effective means for preventing reverse mounting of a reel on a spindle.

Another feature relates to a simple, coinpact, and effective releasable spring latch equipped spindle for releasably maintaining a reel on the spindle.

With these features in view my invention consists in certain features of novelty in the construction, combination and arrangement of parts by which the said features and certain other features hereinafter appearing are effected, all as fully described with reference to the accompanying drawing and more particularly pointed out in the claims.

In the said drawing i igure 1 is a side elevation of a spindle mount structure with a reel shown in central vertical section, mounted thereon.

Figure 2 is a partial front elevation of the spindle mount structure with a reel mount ed thereon.

Figure 3 is an enlarged partial central vertical section of the same.

Figure 4 is a partial perspective view of the spindle.

Figures 5 and 6 are partial views of opposite sides of the reel.

Like characters of reference indicate like parts in the several views.

In the said drawings 1 designates a support arm, and mounted for rotation in a hub of this arm is a spindle 2, the reel mount I portion of which extends outwardly from one end of the hub. This extending portion of the spindle is provided with a longitudinally varied reel mount surface comprising a round outer portion 3 and a square or polygonal inner portion l having its faces tangential to the round portion and accordingly extending laterally beyond the round portion and terminating in an outwardly facing shoulder 5.

The reel includes spaced side plates 6 and T secured in a usual manner to opposite ends of a central tubular member 8, and the side plates 6 and 7 are provided respectively with central coaxial spindle apertures 9 and 10 forming a spindle opening. The spindle aperture 10 of the plate 7 is round corresponding with the outer portion 3 of the reel mount surface of the spindle to fit over the same in the mounting of the reel on the spindle, and the aperture 9 of the plate 6 is square or polygonal corresponding with the inner portion 4 of the reel mount surface of the spindle to fit over the same in the mounting of the reel on the spindle, the sides of the square or polygonal aperture 9 being in planes tangential to the round aperture 10, and, as shown, the length of the sides of the square aperture 9 being the same as the diameter of the round aperture 10, see Figs. 5 and 6, thus forming a longitudinally varied spindle opening corresponding with the longitudinally varied reel mount surface of the spindle. It is an inherent characteristic of a reel with such apertures that it will fit over and rotate satisfactorily on a spindle which is cylindrical throughout, such as one having throughout the same diameter as portion The reel is mounted on and removed from the reel mount portion of the spindle over the outer end thereof, and by reason of the fact that the aperture 10 of the plate 7 will not fit over the portion 4 of the reel mount surface of the spindle, the reel can only be mounted on the spindle in one way, i. e., with the plate 6, having the spindle aperture 9, inward as shown. The engagement of the aperture Jot the plate 6 with the portion l of the reel mount surface of the spindle provides for driving the reel from the spindle.

When the reel is mounted onthe spindle the inner surface of the plate 7, forming a shoulder surface, engagesthe shoulder 5 of the spindle to limit inward movement of the reel. The reel is releasably maintained against outward movement by means new to be described. The reel mount portion of the spindle is bored from the outer end thereof as designated at ll. and is provided with a radial aperture 1; eonnnunieating with the bore of the spindle and disposed at a point adjacent the position of the plate- 6 the portion. 4: of the reelinount surface of the spindle, and the arrangement is such that this portion of the spring is disposed in front of the inner plate (5 of the reel when the reel. is mounted on the spindle and maintains the reel against outward movement on the spindle with the outer plate 7 against the shoulder 5. The spring is depressed to permit the plate 6 to ride over the same in both the mounting of the reel and the removal thereof by excess axial pressure eX-- ert ed on the reel in the proper direction.

lVhile I have herein shown and particularly described the preferred embodiment of myinvention I do not wish. to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention,
