SPECIFIGATION'forming part of Letters 'PatentNo. 536,302, dated March 26, 1895.
Application filed December 14, 1894:. Serial No. 531,785- (No model.)
To all whom it may concern:
Be it known that I, ARTHUR H. SQUIER, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Curtain-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.
My invention relates to means for fastening curtains to rollers, and consists in the combination with a roller provided with a narrow longitudinal kerf in one part of its periphery, and a segmental shouldered depression in another part of its periphery, of a segmental spring fastening device having both of its ends bent inward to form holdfasts, said bent ends being adapted for entering, respectively, the longitudinal kerf and the segmental depression, after the curtain has been passed partly around the roller, and, by binding against the curtain, deflectingit in conformity with the kerf and segmental depression, and thereby fastening it securely to the roller, and holding it firmly against slipping on the same.
The construction of my curtain fastener is such that the segmental spring holding portions can be applied and removed by the hand; and in applying them it is not necessary to have one of their ends sharpened and adapted to penetrate the curtain and roller; and in removing them for any purpose or for application to a new kerfed and rabbeted roller, it is not necessary to-use a tool or pry nor to break ofi penetrating points in order to free the spring portions from the roller.
In the accompanying drawings, Figure 1. is a perspective View, illustrating my improved roller and fastener, in connection with a window or other curtain, a portion of the curtain being broken away. Fig. 2. is an enlarged perspective View of a portion of a roller and curtain; the latter being shown fastened by my improved means. Fig. 3. is a cross section of the parts shown in the other views.
- A in the drawings designates the roller, B the spring fastener, and O the curtain. The
roller is provided on its periphery with a narrow longitudinal kerf a, and a broad depression b, the latter out so as to present a square or other suitable shoulder a, and a broad surfaced base which forms with the shoulder a broad rabbet-likegroove. In order to use a short spring fastener B, the shoulder a is located as near as possible to the kerf a. The depression I) is made by cutting into the periphery of the roller with a rabbetin g tool and itshould be much wider than thekerf a, in order to afford room for manipulating the spring Bin fastening and unfastening the curtain C, but particularly to avoid unduly deflecting or bending the curtain at its fastening portion, beyond the kerf a.
The fastener B is formed of spring metal bent into segmental form, and is of alength, say, equal to about one quarter the circumference of the roller, and is provided with fastenin g portions 0, c, by bending-inwardly the ends of the metal of which the spring is formed. The fastening portion 0 is formed, preferably, by first bending the metal inward and then outward, as shown; this latter being done in order to form a sort of finger-means whereby to spring the fastener out of contact with its shoulder; and also to give increased resistance to the spring fastener at this point.
To fasten a curtain to its roller, in accordance with my invention, a suitable number of spring fasteners B are provided, and the edge of one end of the curtain is inserted into the kerf; and after the curtain has vbeen rolled partly around the roller, the fasteners are sprung into the kerf, and behind the shoulder a of the depression I) as illustrated in the drawings.
My fastener is very cheap, only requiring about one half the quantity of metal employed in other spring fasteners. Its action is very positive at both of its ends, and it is impossible for the curtain to slip on the roller or under the spring fasteners. The spring only extends around about one third of the circumference of the roller, and both of its ends enter below the periphery of the roller, say to a depth of about one eighth of an inch, the kerf being cut in the roller at an angle of about one hundred and twenty degrees, more or less, and the depression formed with a curve or nearly right angular surface so as to retain the spring, and yet not cut the curtain.
What I claim as my invention is- The combination of a curtain fastening spring having a shape conforming to a segin the kerf and the other sprung behind the ment of the circumference of a curtain roller shoulder of the depression of the roller, at any and constructed with its ends turned inward point along the roller, and being retained at 15 and blunt so as to be non-penetrating, and a its ends bya wall of the kerf and the shoulder 5 roller havinga longitudinal kerf and a broad of the depression of the roller, substantially segmental shouldered depression along its peas described.
riphery, said shouldered depression being of In testimony whereof I hereunto aflix my sufficient width to allow one end of the spring signature in presence of two witnesses.
to be conveniently manipulated either in the i ARTHUR H. SQUIER. 10 act of its attachment or detachment; said Witnesses:
spring being adapted, by the manipulation of J. W. BAYLOR,
the fingers, for having one of its ends inserted J. E. WATKINS.
