To all whom it may concern:

Be it known that I, JAMES W. LESLIE, a citizen of the United States, residing in IVakefield, county of Middlesex, and State of Massachusetts, have invented an Improvement in Curtain-Rings and Traverse 'Rolls Therefor, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel cheap and eflicient ring for use in hanging curtains, portieres and the like, the ring being provided with one or more traverse rolls whereby the easy and free movement of the ring along the pole is facilitated.

The construction of the traverse roll and the mode of securing or mounting it in the body of the ring are comprehended in the novel'features of my invention, to be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a front elevation of a curtain ring provided with traverse rolls and embodying one practical form of my invention, the supporting rod or pole being shown in section; Fig. 2 is a greatly enlarged view, partly in section, of the traverse roll and parts cooperating therewith; Fig. 3 is an en-- larged section showing the two-part axle and the construction of the heads and enlargements thereon.

Referring to Fig. 1 I have shown the ring as provided with two traverse rolls, as for general purposes such arrangement secures the best results, the annular ring-body 1 being made of thin sheet metal in tubular form, as is customary. The ends of the body are separated sufliciently, in this instance, to receive two traverse rolls and a distance piece 2, also of tubular sheet metal. The traverse roll may be of any suitable construction, but it is conveniently made of two cup-like pieces 3, 4, Fig. 2, of sheet metal, which are shaped or stain ed into shape, and one is forced within tiie other, as shown, an axial opening 5 being made in each side of the roll. I provide a two-part axle, herein shown as two tubular or hollow studs 6, 7 provided respectively with enlarged flat heads 6 7 best shown in Fig. 8, the stud 6 being large enough to permit the stud 7 to be telescoped thereinto. The stud 7 is long enough to be upset at its inner end at 8, Figs. 2 and 3, to lock the axle members together after they are telescoped. A tubular, sheet metal boss 9 having a contracted neck or external annular groove 10 is secured to each stud head by spinning down the flange 11 over the edge of e head, see dotted lines Fig. 3 and full lines In practice the stud head and boss are first connected as described, and the construction of both the stud and the boss is a very simple and cheap operation, as the parts are quickly made by suitable dies, and by spinning and stamping operations well knownin the art. The two studs comprising an axle, with their attached bosses, are then inserted in the trav erse roll from opposite sides thereof, the end of the outer stud, as 6, abutting against the head 7 as shown in Fig. 3, and then the end of the stud 7 projecting through the head 6 is upset by a suitable tool inserted through the open end of the adjacent boss 9. This locks the studs together, with the roll rotatably mounted thereon between the two heads 6 7 X the latterlimiting lateral play of the roll on the axle without any bending action. The assembled roll and axle are now ready for connection with the ring-body, and when using two rolls the. boss on the outer end of each axle is inserted in the adj acent open end of the ringbody, and the tubular distance piece 2 is inserted between the rolls, receiving the bosses at the inner ends of the axles.

The finishing operation is usually effected by compressing in suitable dies, the parts assembled as described being laid in one half of the die. The other half is then applied, and the halves pressed together, and by so doing the metal of the ring-body is pressed into the grooves 10, as at 12, Fig. 1, and the metal of the distance piece is compressed, at 12, into the grooves of the inner bosses. The ring is now completed, with the traverse rolls in proper position and securely locked in place. In some instances it may be most convenient to lock the distance-piece first, and thereafter lock the ring-body onto the bosses on the outer ends of the axles.

My invention is not restricted to the precise construction and arrangement shown, nor to the particular number. of traverse rolls mounted on the ring-body.

I have omitted the roll in Fig. 3 in order to avoid confusing the other parts illustrated therein.

Having fully described my invention,

Letters Patent is z- 1. In a curtain ring, a traverse roll, an axle on which it rotates, heads on the ends of the axle to limit lateral play of the roll, annularly grooved bosses on the heads, and a tubular ring-body having its ends embracing the bosses and compressed into the grooves thereof.

2. A tubular metallic ring-body, a traverse roll, an axle on which it is rotatably mounted, and annularly grooved enlargements on the ends of the axle, to enter the open ends of the ring-body, the latter being compressed into the grooves to lock the axle and body together.

3. In a curtain ring, an annular, tubular, metallic body having separated ends, a plurality of traverse rolls, an axle for each, having annularly grooved enlargements on their ends, the enlargement on the outer end of each axle being inserted. in the adjacent end. of the body, the latter being compressed in the groove to lock the body and axle together, and a tubular distance piece embracing the enlargements at the inner ends of the axles and similarly locked thereon.

4. A traverse roll having an axial opening, a two-part tubular axle loosely extended therethrough, one part being telescoped into the other, an annular head on the outer end of each part, a hollow, externally grooved boss compressed onto each of said heads, and means to lock the axle parts together.

5. A traverse roll having an axial opening, an axle loosely extended therethrough and comprising two hollow studs one of which is inserted within the other and. upset at its inner end, to lock the parts together, a head on the outer end of each stud, and an externally grooved boss on each of said heads.

6. A traverse roll having an axial opening and an axle therefor consisting of two tubular studs each having at one end an enlarged head and a boss connected therewith by a reduced neck, the studs being inserted in the axial opening of the roll from opposite sides and telescoped one within the other, the innermost stud being upset at its inner end to lock the studs together, the outermost stud maintaining the heads separated.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
