FERR'ULE CONSTRUCTION FOR UNEBRELLAsCOVElES.

Specification of Letters Yatent.

Patented a e, 1915.

Application filed September 23, 1912. Serial No. 721,902.

Construction for Umbrella-Covers, ofwhich the following is a specification.

My invention relates to a. ferrule construction for the centers of umbrella covers,

' neat appearance.

and hasfor its object to provide improved means for attaching the ferrule to the cloth, whereby a secure fastening is obtained, and an article produced which will present a A further object is to provide a ferrule construction which can be rapidly and cheaply applied, without the necessity for skilled labor.

In order that my invention may be clearly understood reference is had to the accompanying drawings, forming part of the specification, and in which:

Figure 1 is a side elevation of the pair of ferrules employed in connection with my invention; Fig. 2 is a side view of one of the ferrules showing a pair of dies which may be employed for assembling, one of the dies being in section; Fig. 3 is a sectional elevation of the dies and ferrules as they appear at the moment of assembling, the umbrella cover being shown-fin position between the ferrules; Fig. 4 1s a simllar view showing the parts as they appear after the assembling operation; Fig. 5 1s a'similar view showing my improved ferrule structure in position on an umbrella stick, the umbrella being shown as closed; Fig. 6 is a similar view showing the umbrella open;

Figs. 7 and 8 are sectional views showing slightly difierent forms of ferrules.

Referring to the drawings in detail, 1 and 2 designate a pair of ferrules of similar shape but of slightly different diameters, the ferrule 2 being shown as the smaller and capable of fitting within the other. These ferrules are preferably of the standard shape usually employed to form the tips of umbrella cases and comprise an upper frusto-conical portion and a cylindrical portion provided with an annular corrugation. I

This corrugation gives rise to the annular shoulders 1*, 2 and the adjacent grooves 11.- 2b

For assembling the ferrules I preferably employ a pair of die" members A, B, the member A having a central stud A of. ap-

proximately the size of the umbrella stick and the member B having a socket 1) provided with a flaring mouth shaped to conform to the conical portion of the ferrules. The die A is also provided with an annular shoulder a and with a rounded portiona,

. for the purpose now to be described.

In assembling the parts, the ferrule 2 is first. placed in position upon the die A as shown in Fig. 2, the lower edge 2 thereof restlng upon the annular shoulder a and the rounded portion a of the die fitting within the base of the ferrule, the upper end of the ferrule engaging the stud A. The umbrella cover 3, having previously been provided .with a suitable opening, is next slipped over the ferrule 2 to about the ex tent shown in Fig. 2. The ferrule l is then placed in position over the ferrule 2 and cover 3 as shown in Fig. 3, and the die member B is then moved downwardly so as to engage the ferrule land force it over the ferrule 2.

Fig. 4 represents the limit of movement of the dies toward each other, and shows the two ferrules as completely telescoping, with the corrugation of one interlocked with that of the other, ,the fabric of the cover being fricti'onally held between the two ferrules. By reference to Figs. 3 and 4 it will be seen that the groove 1* constitutes an inwardly projecting shoulder which must be forced over the external shoulder 2 ,The parts are so proportioned that considerab e pressure is required to produce this telesc ping of'the ferrules, and when the operation occurs the groove 1 snaps over the shoulder 2 into the position shown in Fig. 4 and causes an effectual interlocking of the ferrules, the cloth being gripped between them.

l-Vhile I have shown and described fer-' tions be in the form of grooves extending inwardly from the surface of the ferrule, or in the formof ribs extending outwardly therefrom, or in a construction embodying bothgrooves and ribs, as described. The annular deformation of one ferrule fits .into the corresponding deformation of the other and this is the gist of the invention. As toions other features, the exact shape of the fer may be of any ordinary type found on the market. It will be observed that when the umbrella is closed, as shown in Fig. 5, the

inner ferrule 2 completely 'envelops the notch 6 and the inner ends of the ribs, and thus protects the cloth from coming in contact therewith. The ferrules, however,

although snugly fitting the stick 4, are.

capable of sliding thereon, and when the umbrella is open, as shown in Fig. 6, the edge 2 of the inner ferrule is engaged by the ribs and theferrules shifted upwardly along the stick l. This prevents any binding or cramping of the parts and serves to prevent the cloth from becoming worn by contact with the rib ends at their pivotal points 7.

As shown in Fig. 7, I may in some instances extend the large end of the inner ferrule 2 below that of the outer ferrule l, as shown at 11, while the loweredge of said ferrule may be beaded as shown at 1. The extended end of the inner ferrule engages the ribs when the umbrella is opened, and thus prevents wear of the cover.

In Fig. 8, I have shown a still further modified form of outer ferrule l, the inner ferrule 2 being substantially the same as that shown in Fig. 1. In this arrangement the lower edge of the outer ferrule is turned outward upon itself so as to form-a smooth, broad surface, as indicated 'a 1 so as to prevent wearing or cutting of the cover. Experiments have shown that the construction illustrated in Fig. 8 is very satisfactory and I regard this arrangement as my preferred form. It will be seen'that the bead l -fits into the grooves 2 of the inner ferrule.

It will be noted that the process of attaching the ferrules to the covers is an independent operation from securing such covers to the umbrella frame. The ferrules can be attached to the covers by the use of dies as described, and by cheap labor, and then such finished covers are passed to the skilled laborers known as tippers who can then assemble the covers on the frames without the necessity of any needlework. This results in a material reduction in the cost of manufacture.

What I claim is 1. In a device of the class described two conical ferrules having like annular corrugations near their larger ends, one of said ferrules fitting snugly within the other with Copies of this patent may be obtained for to be shifted thereon as the umbrella is opened and closed, such shifting being produced by engagement of one of said ferrules with the ribs.

3. In an umbrella, the combination with the usual stick, a notch secured thereon, ribs pivotally connected to said notch, a cover secured to said ribs and a pair of ferrules surrounding said stick and disposed one inside and the other outside of said cover, said ferrules having interlocking corrugations with the fabric between such corrugations,

said interlocked ferrules being freely slidable on said stick and completely enveloping said notch when the umbrella is closed,

said ferrules being arranged to be shifted outwardly on said stick by engagement of the ribs therewith as the umbrella is opened.

4. In a device of the class described two conical ferrules having like annular corrugations near their larger ends, one of said ferrules fitting snugly within the other with said corrugations interlocking and holding the parts together, and an umbrella cover, or the like, frictionally gripped between said ferrules, the larger end of said outer ferrule being turned outward upon itself to provide a smooth bearing surface for' the cover, the end of the inner ferrule projecting beyond such surface.

5. In a device of the class described two conical ferrules having like annular corrugations near their larger ends, one ofsaid ferrules fitting snugly within the other with said corrugations interlocking and holding the parts together, and an umbrella cover, or the like, frictionally gripped between-said ferrules, the inner one of said ferrules hav ing its larger end extending beyond the larger end of the outer ferrule, such extending edge being adapted to engage the ribs when the umbrella is opened.

In testimony whereof I affix'my signature, impresence of two witnesses.
