to the shrinkage of the wooden handles; and even with screws, nails or other retaining devices passed through the head to handle, the heads become wabbly on the handles. Where no such fastening devices are employed the head slips from the handle, particularly during manipulation of the device or implement.

The particular socket s onstructed of sheet me nly, as mon use have sockets o, and various other types of heads, ooms, window brushes handle so as to form shoulders in the wooden handle trending in the direction of its circumference, to thereby prevent removal of the ferrule from the handle. y With these and other objects in View to appear hereinafter, my invention consists in the new method of securing a ferrule to a handle; in the novel features of construction, and in the arrangement and combination of parts to be hereinafter described and more particularly pointed out in the subjoined claims.
In the drawing:
Fig. 1 is a perspective View of a mop head havthereto or forming part die having a ferrule conh my invention posiective view of the ferrule in it is applied to the wooden t, my invention includes designated by the numeral 7, which manner illustrated so applied to an impledusting or polishing swab. This arrangement, however, is shown for purposes of illustration o of mop heads now in com applied theret such as heads of brush 'or and the like may be substituted from the head shown. In every case, however, a socket is to be ive the handle, and in the socket various types for the purpose herehown in the drawing tal, and the metal is indented inwardly, as at 9, to form internal nubs l0. One or more of these nubs may be employed. I have found the best results to be secured by positioning these nubs at dia1netrically opposite points of the socket.
1l designates the usual wooden handle, and 12 a metallic ferrule applied to one end thereof. While the ferrule may be applied to the handle without tapering the handle at the region of application, I preferably taper the handle and correspondingly taper the ferrule, and it may be here stated that the general practice is, regardless of the formation of the socket otherwise, that such socket be slightly tapered inwardly.
The ferrule 12 is applied to the handle when in the form shown in Fig. 6; that is to say, it is of true circular formation throughout its length. It may or may not be closed at its outer end, but to prevent the forcing of the wood outwardly beyond the outer end of the ferrule, I preferably construct the ferrule with an outer end wall 13. The errule in the form shown in Fig. 6, is thrust over the end of the handle, preferably tapered for the purpose, and after being applied thereto the ferrule-end of the handle is thrust between dies which are closed thereupon to create exterior retainer grooves 14 therein, the pressure exerted to form these grooves creating internal ribs in the ferrule and causing the fibers of the wood withinthe ferrule to be compressed, thereby assuring that even after the shrinkage of the wood, Vsuch shrinkage will have taken place only in directions at angles to the plane in which the grooves are formed in the ferrule, such grooves being preferably formed at diametrically opposite regions of the ferrule.
Moreover, it is intended` that these grooves be of the common bayonet formation; that is to say,
they are provided with longitudinal portions 15 and right-angled portions 16 at the inner ends of the longitudinal portions, said right-angled portions preferably terminating in recurved or :ce-entrant extremities 17.
It is to be particularly noted that the for1ning of the right-angled portions 16 of the grooves at the inner ends of the longitudinal portions 15 thereof result in the formation of circumferentially-trending shoulders 18 in the wood at diametrically opposite regions of the handle, the lower Vof these shoulders preventing withdrawal of the ferrule from the handle.
When connecting the handle to an implement having a socket, the ferrule end thereof is thrust into the socket '7, with the result that the nubs 9 enter the longitudinal portions 15 or" the bayonet grooves 14, and as these nubs reach the inner ends of said longitudinal portions, the socket is turned upon the handle, or the handle within the socket, to cause the nubs 8 to pass through the transverse or circumferentially-trending short groove portions 16 and enter the recurved or reentrant portions 17 at the extremities of the grooves, the nubs 8 resting within said re-curved or re-entrant portions and preventing rotation of the handle within the socket or the socket on the handle.
The advantages of my improved ferrule will be apparent from the foregoing description, but it may be stated that heretofore, when metallic ferrules were employed, it has been necessary, in order to manufacture at a price demanded by the trade to use pins, nails, or the like which the handle to prevent accidental or unintentional removal of the ferrule from the handle. In all cases, however, the wood of the handle becomes shrunken after a time and the ferrule is only wabbly retained on the handle. Eventually the nail or other retainer device employed to secure the ferrule to the handle becomes loosened, by wearing into the bresrof the woods, and this practically renders the handle useless or at least uncontrollable.
It may be further stated that handles of this type generally in use are exceedingly cheap and are fashioned from unseasoned material; that they often become wet and swell, and when dry shrink to subnormal diameter.
With my construction, the compressing of the wood fibers within the ferrule results in reducing the handle along a diametral region or dimension or to a size beyond that possible for the wood fibers to shrink, and assurance is had, regardless of the length of time the handle is used, that the ferrule will be securely retained thereon. .Having thus described my invention, what I claim is.
1. An implement connector, comprisingV a socket having a nub stamped therefrom and projecting( thereinto, and a wooden handle having a metallic ferrule thereon inserted into said socket and provided with an angular exterior retainer groove adapted to receive said nub, said groove creating an angular interior rib in said ferrule forced into the fibers of the wooden handle both in the direction of the trend of said fibers 'and crosswise thereof. Y
2. In a connector for implements, a sheet metal ferrule applied to one end of a wooden handle and having anl exterior retainer groove trending in different directions formed therein to create an interior rib in said ferrule, said rib being pressed into said wooden handle to form shoulders in the latter trending in directions correspond ing to that of said retainer groove and thus'prevent endwise and rotative movement of they ferrule from the handle.
