ADJUSTABLE FERRULE.

Specification of Letters Patent.

Patented July 2, 1907.

Application filed December 4, 1906. Serial N0. 346,351.

To all 'whomrat 'may concern:

Be it known that I, LAURENCE A. CANTWELL, a citizen ofthe United States, residing at Riverside, in the county of Riverside and State of California, have invented certainlnew and useful Improvements in Adjustable Ferrules, of which the following is a specification.

Handles for garden hoes, rakes and for pitch forks and like tools and implements require the end receiving the shanks of the several tools to be reinforced by means of a ferrule which usually consists of a band, or sleeve, forced upon the handle and secured in place in various ways, either by indenting by means of a sharp punch, or by means of a tack or screw passed through an opening of the ferrule into the handle. It is not an uncommon occurrence for the ferrule and handle to be of such a size as not to readily lit; hence time is consumed and annoyance experienced in properly fitting the parts, and in the event of the ferrule being larger than the handle, the difficulty is increased by the necessity of building up the handle to fill the ferrule so as to insure retaining the same in place after the parts have been assembled.

The purpose of the present invention is to provide an adjustable ferrule which may be readily conformed to different sizes of handles within certain limits, the ferrule being adapted either to be contracted, or to admit of expansion to meet the exigencies of the particular case.

AFor a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following' description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof still the preferred embodiment is shown in the accompanying drawings, in which:

Figure l is a perspective view of a hoe having its handle provided with a ferrule constructed in accordance with the invention. Fig. 2 is a detail perspective view of the ferrule, the position of the key being shown by dotted lines. Fig. 3 is a transverse section on the line x--x of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of -the drawings by the saine reference characters.

The ferrule lis of circular outline in cross section and may be tapered throughout its length, or of cylindrical formation according to the general design thereof.

In its formation, the ferrule is constructed of a blank of sheet metal rolled, or bent, upon itself into approximately circular outline. The ferrule is provided at, or near, one end with a wing, or extension 2, `and at or near its opposite end with a corresponding wing, or eX- tension 3, said wings, or extensions, being adapted to overlap the opposite edge portion of the ierrule from that provided with the said extensions. A' fastening 4, such as a screw, tack, or the like, is passed through corresponding openings in the extension 2 and the opposite edge portion of the ferrule overlapped by said -extension and enters the handle 5 to retain the ferrule in place and to hold the edge portions together. The wing, or extension, 3 is provided with an opening 6 and its outer edge is recurved as shown at 7. A wing, or eX- tension 8, projects from the edge ofthe ferrule opposite to that provided with the wing, or extension 3 and is adapted'to pass through the opening 6 and its end is recurved as shown at 9. The recurved ends 7 and 9 iiare to correspond approximately to the taper of the ferrule and to the taper of the cooperating key 10 which is adapted to be forced between the said recurved ends so as to contract the lower end of the ferrule. By having the wing 8 pass through the opening 6 of the wing 3, the lower portion of the ferrule adjacent to the separated edges is prevented from lateral displacement, and after the key 10 has been forced home between the recurved ends, 7 and 9 of the wings, the ferrule is made secure and caused to conform to the size of the handle at its lower end.

rIhe ferrule is adapted for handles of tools, household articles and devices generally requiring the handles reinforced to guardagainst splitting.

While the construction illustrated is preferred, i. e., to have the wing 8 pass through an opening of the wing 3, yet various modifications of the invention will suggest themselves to the skilled mechanic, the essential lfeature of which is a ferrule adapted to contract-and ex pand and adapted to be constructed by means of a key of wedge form forced between cooperating parts of the ferrule bordering upon the slit or opening.

Having thus described the invention, what is claimed as new is:

1. An expansible ferrule and a slidable key coperating therewith to contract the ferrule and secure the same in an adjusted position.

2. An expansible tei-rule provided with projecting portions spaced apart, and a key to be pressed between said projecting portions to draw the ferrule together and secure thesame in an adjusted position.

3. An expansible ferruie having extensions provided with recurved portions and a key adapted to be pressed between the said recurved portions for contracting the ferrule.

4. A ferrule having extensions which are adapted to overlapand have their terminal portions recurved and a key adapted to be passed over the overlapped portions of the extensions and between the reeurved portions thereof.

5. A ferrule provided with extensions, one of said extensions havng an opening and the other passed through said opening and between extensions having recurved p01'- tions. and a key adapted to be passed between the re- Curved portions of said extensions.

6. A ferrule consisting of a blank bent into approximately circular form and having overlapped 'portions at one end and overlapped extensions at the opposite end 10 provided with recurved terminal portions, a pivot fastening connecting the overlapped portions of the fel-rule :it one end, and a key passed between the reeurved overlapped portions at the opposite end of said ferrule.

In testimony whereof I ailx my signature Ain presence of two witnesses.
