Feb. 15, "1944. D. H. STOREY WINDING REEL Filed Feb. 27'. 1943 INVENTOR DANlEL H.STOREY AT TORNEYS Patented Feb. 15, 1944 UNITED STATES PATENT OFFICE WINDING REEL Daniel H. Storey, Wausau, Wis. Application February 27, 1943, Serial No. 477,344

2 Claims.

My invention has for its primary object to provide a simple, economical and effective reel for winding lengths of flexible material into compact units, it being understood that the reel is especially adapted for winding short lengths of film strip or it may be utilized for winding bandages, ribbons, lengths of fabric, tapes or cords. As a matter of fact, any flexible material in lengths may be conveniently coiled upon the spool of the reel.

Another object of my invention is to provide the hub or spool with a manually contractable sector, whereby the coiled material thereon may readily be stripped or removed intact from one end of the hub for storage or other purposes.

With the above and other minor objects in view, my invention consists in certain peculiarities of construction and combination of parts as will be hereinafter set forth with reference to the accompanying drawing, in which drawing:

Figure 1 is a sectional, elevational view of a winding reel embodying the features of my invention, the section being indicated by line l--l of Figure 2.

Figure 2 is a front elevational view of the same.

Figure ,3 is a top, plan view of the winding reel.

Figure 4 is a fragmentary, front, elevational view of said reel in section through th spool or hub unit, the section being indicated by line 4-4 of Figure 1.

Figure 5 is a detail, sectional, rear, elevational view as indicated by line 55 of Figure 1, the same particularly illustrating the manual means for contracting the hub or spool.

Referring by characters to the drawing, l indicates a bracket for attachment to any suitable support having extended therefrom a foot 2 and a clamping screw 3. The top portion of the bracket is provided with a bearing hub for a crank shaft 5 provided with a standard crank handle. The end of the shaft has mounted thereon a reel unit embodying a front'spool or hub 6 and a rear circular flange 7, which flange, as best shown in Figures 2, 4, and 5, is interrupted radially to form a stripping gap A that extends from the hub.

As best shown in Figures 2 and 4 of the drawing, the reel is provided with a fixed hollow spool or hub sector 8 riveted or otherwise secured to the flange i and a swinging spool sector 9 mounted upon a stud iii. 1

The swinging or contractable hub sector is held in its normal position, concentric to the fixed sector, by a spring H, which is secured to the fixed hub sector by means of a screw 12 passing therethrough and the end of the same impinges against the shaft 5, which serves to lock the reel to said shaft.

Referring to Figures 1 and 4, it will be noted that the concave convex spool sector's, one of which is pivoted to the flange I and the other firmly secured thereto, together form a shell shaped about the shaft 5, whereby the leaf spring I I encircles said shaft and in said position is concealed and protected.

The swinging sector 9, has projecting rearwardly through the gap A, a gripping pin it, which pin is associated with a corresponding fixed pin 13, which extends rearwardly from the flange 1.

In this exemplification of my invention, the gripping pin I 3, which extends through the fixed sector 8, also serves as a rivet in conjunction with the stud l0 for securing a front closure hub disc I4, which is also centrally secured by upsetting the end of the shaft 5, whereby the hollow hub is enclosed.

As best indicated in Figure 2 of the drawing, this closure disc I 4 is cut away opposite the movable hub sector 9 eccentrically with reference to the reel axis, to permit stripping clearance from the hub end of a coil of material.

As best shown in Figures 2 and 4 of the draw ing, the fixed hub sector is provided with a longitudinal channel l5 for the reception of the end of the material wound upon the spool, whereby a lock is formed to prevent slippage of said material upon the hub when tension is put upon the same for coiling purposes.

As previously indicated, the reel is particularly adapted for Winding short lengths of photographic film strip, to be thereafter removed from the reel hub and stored for future attachment to other strip lengths.

From the foregoing description, it will be obvious, that when a short length of film strip is to be wound, the inner end of the same is fitted into the hub groove l5 and tension is then put upon the loose end of said strip. The reel is then re volved until the strip is entirely coiled tightly thereon, as best shown in Figures 2 and 4. The tightly coiled strip can then be quickly removed without tendency of the coils to slip in conical formation, with reference to the axis of the spool, by simply squeezing the pins i3 and i3, whereby the spool is contracted from its circular formation and the strip can then be slipped from the front end of the spool, by pressing the inner rear coiled edges of the same with the fingers through the gap A of the flange, while at the same time the coils are being held from expand ing with the other hand of the operator grasping the outer turn of the strip coil, whereby it will be manually pushed from its hub portion evenly and thus prevent dishing or coning in either direction. The removed windings of the strip will then be in perfect formation for storage.

In the exemplification of my invention I have illustrated the retractable hub sector as a shell arrangement under spring control. However, it is obvious that the contractable hub, may be formed from a fixed sector and a spring shell sector, in fixed relation at its lower end to the hub, while its upper end may be free with any means for contracting it from its normal circular position.

It is also obvious that as a substitute for a direct crank drive on a reel I may employ a speed up gear connection for the drive.

While I have shown and described one exemplification of my invention, minutely as to detail, it is understood that I may vary such details within the knowledge of the skilled mechanic.

I claim:

1. In a strip winding device comprising a bracket and a bearing therein, a rotary shaft mounted in the bearing, a strip receiving spool secured to the shaft the same including a fixed sector, a rear circular flange extending therefrom, the same being radially interrupted to form a rear stripping gap, a movable sector pivotally associated with the fixed sector, a spring for normally holding the movable spool sector concentric' with the fixed sector and a pin extending rearwardly from the free end of the movable sector through the circular flange strip gap.

' 2. A strip winding device comprising a bracket having a bearing therein, a rotary crank shaft mounted in the bearing, a flange surrounding the shaft, a shell like hub sector fixed to the flange and extending therefrom about the shaft, a sec- 0nd circular shell like hub sector pivoted to the flange, and a circular leaf spring nested within the shell like hub sectors for expanding the pivoted hub sector to a position concentric with the fixed hub sector.
