JOHN H. KnnsrING ANnvrNcnNfr a. kansarme, or New YORK, N. Y.

FEB/RULE,

Application filed February 2, 1922.

To all who/m, t may concern.'

Be it known that we, JOHN H. KERSTING and VINCENT J. KNRSTING, citizens of the United States, residing at New York, in the county of New York, State of New York, have invented a new and useful Ferrule, of which the following is a speciication.

This invention aims to provide novel means whereby the ends of a tubular me'- tallic member may be held together so securely that-they cannot be separated by anyV force short of one which would work a destruction of the member.

i The device is of general application, but is adapted to be used as part of a paint brush, and when so used, will present a smooth surfaceI` which will not interfere with the introduction of the handle or the bristles. Y

It is within the province of the ,disclosur to improve generally and to enhance the utility of devices of that type to which the invention appertains.

'Wth the above and other objects in View, whichV will appear as the description proceeds, the invention resides in the combina- .V tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure l shows in side elevation, a device constructed in accordance with the invention; Figure 2 is a side ,elevation wherein the structure is viewed'at right angles to the showing of Figure l; Figure 3 is a section on the line 3-3 of Figure 2; Figure 4L is a section on the line 4 4, of Figure 2; Figure 5 is a section on the line 5 5 of Figure 2.

In carrying out the invention, there is provided a tubular metallic member 1, the

endsV ofV which are denoted by the numerals' -2 and 3. The end 2 has 'a hook-shaped bead,

comprising a body 4; a lip V5 nand a bendV 6 connecting the lip with the bdy. The end 3 is supplied with a hook-shaped bead, including a body 7 a lip 8 a bend 9 connecting the lip and the body, and an offset shoulder l0 connecting the body 7 with the end 3 of the tubular member.

Serial No. 533,737.

The hook-shaped beads above described are interengaged as shown in Figures l and 5, the shoulder l0 bearing against the bend 7, so that the joint at the point indicated by the ,numeral l2 is inappreciable. Recalling that Figures at and 5 are drawn on a greatly enlarged scale, it will be obvious that whe-n the device is made of metal of the thickness usually employed `for paint brush ferrules, stove pipes and the like, the inner surface of the ferrule, at the point l2 will be practically smooth.

rThe parts a, 8, 7 and 5 are bent outwardly to form spaced bosses ll, the bosses on the said parts l, S, 5 and 7 being interlocked. Giving to the interlocking.;` of the bosses, the ends 2 and 3 of the ferrule will be held tightly together and, when the ferrule is used as a part of a paint brush neither the swelling of the bristles nor the swelling of the handle, due to moisture, will have the slightest effect in bringing about a separation. rEhe spaced bosses 11 may be of any desired form. As shown in the drawings they are of quadrilateral outline, oppositely disposed angles of the bosses being located in a straight line which is parallel to the aXis of the tubular member l-an observation which will be understood readily when Figure 2 of the drawings is examined. Although the specific shape of the bosses above alluded to is not insisted upon, it is useful, in that, when the bosses are constructed and arranged as above set forth, any paintor other liquid on the outside of the tubular member l, will flow readily, longitudinally thereof, the bosses 1l shedding the paint or other substance, and permitting the same to run longitudinally of the tubular member.

If desired, the Vtubular member l may be circumscribed by the usual ribs 14, common in devices of the kind described` and forming no part of the present invention.

The bosses ll are struck outwardly and Vnot inwardly. Consequently, the inner surface of the tubular member l is not encumbered, but is smooth, it being possible to introduce the handle of a paint brush into the tubular member and with equal facility, to introduce the bristles of the brush thereinto.

Having thus described the invention, what is claimed is:

A deviceof the class described comprising a tubular member provided at its ends with coV ' 5 Vangles of the bosses being located in a? Y foppostely extended nterengaged hoek- `as our own, wehave hereto'afxed our sgna'- hfaped beads, the beads being distorted to turesrin the presence of twowitnesses.VIV
