Application June 30, 1939, Serial No. 282,129

4 Claims. (01. 135-54) This invention relates to a ferrule for an um- The second object of the invention is the production of a ferrule for an umbrella stick, cane and the like which can be quickly and securely locked in place on sticks or canes of diiferent diameters.

The third object of the invention is the production of a ferrule, which is light in weight and strong in construction to preventbreakage when pressed against the ground.

' The fourth object of the invention is the production of a ferrule which is ornamental in appearance and which easily sheds any water from its outer surface and which can be easily cleaned.

' In the accompanying drawing Fig. 1 represents an enlarged elevation of an exemplification of the improved ferrule with its stick; Fig. 2 shows a top view of Fig. 1; Fig. 3 indicates a partial section of Fig. 2 on the line 3, 3; Fig. 4 shows a botton view of Fig. 1 with the stick removed and Fig. 5, is a view similar to Fig. 4 with a modification.

The ferrule can be made of plastic or other suitable material, and comprises the semi-spherical head 20, which has integral therewith the hollow stepped body portion designated in its entirety by the numeral 24. The latter comprises the stepped

annular portions

25, 26 andi2'l, which increase in diameter from the top to the bottom portion of the ferrule and form the shoulders 28, 29 and 3|]. An annular shaped collar 35 extends from and below the annular portion 21 and forms the roof 35, with the body portion 24, and has integral therewith the shoulder 31 on its inner surface.

A longitudinal cylindrical axial cavity 40, hav ing the fiat upper face 4|, is provided for the body portion 24, and extends from the roof 36 to a small distance below the semi-spherical head 20. Longitudinal clamping projections 45, triangular in cross section and tapered from their top ends 46 to their lower ends 41, extend from thesurface of the cylindrical cavity throughout its length. From the fiat upper face 4| of the cavity 40, extend the similar transverse clamping projections 50 and 5|, which are triangular in cross section and at right angles to each other. Their ends are interposed between the top ends 46 of the clamping projections 45.

The stick 55, which supports the ferrule is shown partly broken away.

Attention is called to the position of the transverse clamping projections .55 and 5!, and which are not in line with the clamping projections 45,

.and thereby the upper end of the-stick 55, is preserved and protected from injury by the said

projections

45, 55 and 5|.

Referring to Fig. 5, the longitudinal cylindrical axial cavity 42, is again indicated in the body 10 portion as already described. The annular collar is again indicated at 35 with its shoulder 3'1, and the longitudinal clamping projections are. again shown at 45, but the

crosswise clamping projections

55 and 51 are omitted. 15

To secure the ferrule in place, the upper end of the stick 55, is forced into the cavity 40, to engage the cylindrical surface of the stick with the projections and its top end with the projections and 5|, the projections entering the stick. By this means the said ferrule is tightly clamped to the stick. v j

When the ferrule is in place, the collar 35 with its shoulder 37 is positioned over the collar, not shown, which engages the top ends of the ribs of the umbrella. P

In the present exemplification the stick is of a diameter to exactly fit the cavity 4i), and. the longitudinal projections 45 engage said stick throughout their full length. Should the stick be somewhat smaller in diameter than the cavity 45, the projections 45 would not engage thestick throughout their full length, but would, however,- clamp the stick in place.

Various modifications may be made in the in vention and the present exemplifications are to be taken as illustrative and not limitative thereof.

Having described my invention I claim:

1. A ferrule for a stick comprising a body portion having a longitudinal cavity therein and having longitudinally tapered longitudinal pro-. jections projecting from the surface of said cavity. 7

2. A ferrule fora stick comprising a body portion having a longitudinal cylindrical cavity therein and having longitudinally tapered longitudinal projections, triangular in cross-section, projecting from the surface of each cavity.

3. A ferrule for a stick comprising a body portion having a longitudinal cylindrical cavity therein with a flat upper face and having longitudinally tapered longitudinal projections, triangular in cross-section extending from the cylindrical surface of said cavity and havin clamping projections triangular in cross-section extending from the upper face of said cavity.

4. A ferrule for a stick comprising a body portion having a cylindrical cavity therein with a flat upper face and having longitudinally tapered longitudinal projections triangular in cross-section extending from the cylindrical surface of said cavity and having transverse clamping projections triangular in cross-section extending from the upper face of said cavity and positioned with their ends between the top ends of the longitudinal projections.
