SPOOL OR REEL.
No. 866,039l
Specification of Letters Patent.
Patented Sept. 17, 1907.
Application filed October 29,1906- fBerial No- 341.007.
To all whom it may concern:
Be it known that I, FRANK B. LA MAY, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Spools or Reels; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings,
forming a part of the specification, and to the referonce-numerals marked thereon.
My present invention relates to spools or reels and particularly to that type designed for winding tape or ribbon such as the spools used with the inking devices of typewriting machines to feed the inking ribbons back and forth between the types and platen, and it has for its object to provide a cheap and serviceable article of this description having means for attaching the end of the ribbon or other material thereto and holding it securely against the drum during the winding operation, no matter in which direction this takes place.
A further object of my invention is-to so arrange said attaching means as not to interfere with the regularity of the convolutions of the ribbon whereby the capacity of the spool would be reduced.
To these and other endsthe invention consists in certain improvements and combinations of parts, all as will be hereinafter more fullyexplained, the novel features being pointed out in the claims at the end of the specification.
In the drawings: Figure 1 is an end view of a spool constructed in accordance with my invention. Fig. 2 is a top plan view thereof. Fig. 3 is a transverse central section on the line 3-3 of Fig. 2 showing a ribbon with its end attached. Fig. 4 is a longitudinal central sec- 7 tion on the line 44 of Fig. 1. Fig. 5 i1lustrates the blank from which the drum is formed.
Similar reference numerals in the several figures indicate similar parts.
In the sale of such articles as typewriter ribbons which are preferably furnished wound upon a reel ready to be inserted in the machine for which they are adapted, and which are discarded together with the reel when they have served their period of usefulness, a reel is demanded of a construction so light and simple as to be cheaply manufactured yet capable of holding the end of the ribbon securelythereon so that it will not become detached when unwound and the direction of the feed reversed to wind back thereon from the other reel. To such uses spools embodying my improvements are particularly suitable, and referring now to the drawings, 1 indicates preferably circular sheet metal end flanges provided with radial perforations 2 as desired to reduce the weight thereof and between which extends the winding drum 3. The'latter is tubular in form, being con-.
veniently rolled from sheet material and has its ends supported within grooves or depressions formed by annular concentric ribs 4 of corresponding diameter stamped in the inner faces of the flanges. A tubular bearing member or pin 5 for the reception of a spindle passes centrally of the spool within the drum, the ends of which are upset or otherwise secured against the outer faces of the flanges holding the drum firmly in place and maintaining the rigidity of the spool as a Whole. I i
The ends of the sheet forming the drum (illustrated in Fig, 4) are not brought together but to within a short distance of each other, forming a slot or opening paraleasily admit the end of the ribbon the spool is designed to carry. One of said ends thus opposed, is provided with a tooth or spur 7 as an extension thereof, which is formed to incline downwardly within the drum, and thence upwardly so that its point projectswithin an aperture 8 arranged in the other a short distance from the edge of the slot. The winding surface thus produced is, with the exception of the slot, smooth, even and perfectly cylindrical.
To attach the ribbon (indicated in Fig. 3 by the numeral. 9), a fiat metal strip or such other suitable threading device as will serve to thrust the end thereof within the slot 6, is used, the spur 7 being depressed thereby until the threader is withdrawn, when it will rise and impale the ribbon, the point of the spur being then within the aperture 8 which substantially locks the ribbon against disengagement. The strain exerted upon the latter tends only to strengthen the connection as whenwound in the direction in which the spur extends, the ribbon binds upon the blind edge of the slot while in the opposite direction it is drawn more firmly against the spur., It is preferable to construct the drum of a reasonably elastic material to give the proper degree of resiliency to the spur thereon.
I claim as my invention:
1. In a spool or reel, the combination with the sheet metal end flanges having grooves stamped in their inner faces forming projecting ribs on their outer faces, of a tubular winding drum extending between said end flanges and having its ends supported in the grooves therein and a rigid connection between the flanges.
metal end flanges having grooves stamped in their inner faces forming projecting ribs on their outer faces, and having apertures arranged centrally thereof, of a tubular winding drum extending between said end flanges and having its ends supported in the grooves and a connecting means extending through the apertures in the end flanges and rigidly secured therein.
2. In a spool or reel, the combination with the sheetv lel with the axis thereof, and of a ,width sufficient to I 3. In a spool or reel, the combination with the sheet metal end flanges having grooves stamped in their inner faces forming projecting ribs on their outer faces and having apertures arranged centrally thereof, of a tubular winding drum extending between said end flanges and having its ends supported in the grooves and a bearing member comprising a tubular pin extending through the apertures in the end flanges and rigidly secured therein.
4. In a spool 01' reel, the combination with the end 10 flanges and a drum secured between them having a slot or opening therein and provided with an aperture adjacent said opening, of :1 resilient ribbon impaling spur on the drum projecting through the opening and within the interior of the drum and having its point turned upwardly to cofiperute with the aperture.
