PATENTED' JAN. 13,1903.
D.H. HAYWOOD. v COMBINED SHEET AND ROLLER.
UNITED STATES PATENT OFFICE.
DANIEL HOWARD HAYWOOD, OF NEW YORK, N. Y.
COMBINED SHEET AND ROLLER.
SPECIFICATION forming part of Letters Patent No. 718,347, dated January 13, 1903.
Application filed February 13, 1902. Serial No. 93.846. (No model.)
To all whom it may concern:
Be it known that I, DANIEL HOWARD HAY.- WOOD, a citizen of the United States of America, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in a Combined Sheet and Roller, of which the following is a specification, reference being had to the accompanying drawings,forming a part thereof.
My invention relates to methods of connecting flexible sheets to their supporting-rollers and it consists, essentially, in the new and improved method, as set forth herein, of winding certain portions of the sheet in opposite directions upon the roller.
The object of myinvention is to so connect a flexible sheet to its supporting-roller, and upon which it is adapted to be wound, as to prevent the liability of its being torn off when unwound to the desired limit.
The following is a detailed description of the method of attaching a flexible sheet to a roller according to my invention, thenovel features of which invention are later specifically pointed out in claims.
In'the drawings, Figure 1 is a view in perspective of a combined flexible sheet and roller embodying my invention, with the sheet unwound from the roller to the extreme limit allowed. Figs. 2 and 3 are views in transverse section of the same. Fig. 4: is a sectional view, taken on the same plane as Fig. 2, showing the sheet partially wound. Fig. 5 is a face View of a flexible sheet removed from its roller. Fig. 6 is a View of a shaderoller and shade constructed according to my invention. I
In carrying out my invention I slit a flexible sheet at or near its end, and I secure the alternate portions of the sheet thus slit to opposite sides of the said roller. A roller and flexible sheet so slit are illustrated in the drawings herewith and are designated, respectively, by the reference characters a and b.-
The slits are shown at c, the portions between forming tongues d. The slits may, if desired, extend clear to the end of the sheet or may terminate before the end of the sheet is reached, leaving an unsevered portion 6, as shown particularly in Fig. 6 of the drawings.
In attaching the sheet to the roller the end e may first be secured thereto and the sheet partially wound on the roller in the direction in which it is desired to finally wind the rest of the sheet. The tongue or tongues cl may then be Wound in the opposite direction and secured in any desired manner to the roller. The sheet will now be attached to the roller in such a manner as to produce a tension upon the roller in both directions of rotation thereof when the sheet is unwound to its extreme limit, and the liability of the sheet to become torn off by accidental overunwinding will be practically eliminated. In rewinding the tongue portions will bend at a point, asf, and the sheet may be wound up without any trouble and without any appreciablevariation of thickness as would cause the sheet to buckle or cramp. In practice I find that the pointf once determined becomes a set crease and at the same point. Fig. 4 shows the sheet in the act of rewinding with the tongue folding into place.
When the material of which the flexible sheet is composed is of paperas, for instance, for the perforated-paper music-sheet employed for controlling automatic musical instrumentsI preferably form a number of tongues, as shown'in Figs. 1 and 5; but if the material is cloth, as for cloth window-shades, one or two such tongues are ordinarily sufficient.
In Fig. 6 of the drawings I have illustrated a cloth shade secured to its supporting-roller and having but a single tongue 01 formed at a point about midway between the side edges of the sheet and extending entirely to the end thereof. The sheet may be secured to the roller by tacking or otherwise in the manner commonly employed, with the tongue portion so secured upon the opposite side of the said roller.
My invention is particularly adapted to Window-shades, and is designed to obviate the annoyance of the shade being torn away from its supporting-roller, as now so commonly ocours, on account of the exceedingly small tacks necessarily employed to secure the shade to the roller in order not to interfere with the proper working ofthe shade-roller spring.
hat I claim is- 1. The combination with a roller, of a fleXible sheet connected thereto at one end only, such connection being by attaching-strips, at such end of the sheet, said attachingstrips Wound in opposite directions about said roller, the portions of said strips adjacent to the flexible sheet being free, and the point of junction of the strips with each other, or with the sheet, being beyond the surface of the roller when the sheet is fully unwound.
2. The combination with a roller, of a flexible sheet connected thereto at one end only,
