My invention relates to handles of the v l forming theV locking spurs.

class used upon spades, shovels and some a suitable tool for other tools which consistof a bifurcated element having its branches connected at their ends by a transverse holding or hand-gripping member, and ofl the type of such handles in which the forked member is formed of sheet metal stamped into suitable form to form at its base a stale socket engaging a wooden stale member and having the two branches formed with a Vpair of terminal grip sockets arranged to be connected to a wooden cross-grip which extends between them. The object of my invention is to provide improved means for locking the wooden grip member in the sockets in a simple, sightly and secure manner, so that the appearance of the handle will not be marred, yet the grip member will be so effectively held that it cannot get loose and chatter, even after considerable usage. It has been found that the various forms of locking lugs, fins, or other protuberant members heretofore employed in the prior art, so far as known to me, are all subject to becoming loose and chatteringrunder any usage which produces frequent or constant jarring of the handle, and the object of my invention is to obviate this defect in a desirable and effective manner. To, this end I have devised the tool handle hereinafter described in detail7 the essential elements of my invention being more particularly pointed out in the appended claims.

Figure l of the drawings illustrates a tool handle having a bifurcated sheet metal member engaging a wooden grip and provided with locking means embodying my invention;

Fig. 2 is an end or face view of the out-V side of one of the grip sockets, showings the shape of the cut which is made in forming the locking spurs;

Fig. 3 is a fragmentaryjvertical diametrical section of the same portion of the handle as that illustrated in Fig. 2, showing the locking spurs bent inwardly and imbedded in the grip, the plane of the section being indicated by the dotted line 3 3 of Fig. l; and

Like Vreference characters indicate like4 Y parts in all the igures of the, drawing. j

The exact pattern of the sheet metal member of a tool handle tol which 'my inf vention is` applicable may varyin several respects, solong as itis formedtoprovide Y at the ends of the two branches 1-l of the handle inwardly-facing cup-shaped4 grip sockets .f-f2. The ends of the wooden grip 8 of., the. handle are these sockets, and thewhole secured firmly and rigidly together by a bolt 4. extending longitudinally through the grip` and riveted at its ends as securely as possible to said l Preferably,"and according to com-` sockets. monV practice, the bolt extends through the gripeccentrically of the sockets, as illustrated, so that .itis incapable of rotating in the sockets. i

vThe handle having the parts assembled thus 'far described, the are afterwards locked been constructed and together in av novel manner now to be described, to forni the By meansof a suitable Fig.` 4, the metal of each:l upon two parallel linesg co c completed handle.

punching tool a, see grip socket is out and a transverse central line, approximately in the shape of the letter H, as illustrated in Fig. 2, so las to yprovide two rectangular spurs 5 5 j lying between the parallel cuts and having their free edge directed'towards each other from uncut metal, and as these spurs are cut and formed they are forced or driven down into the wood by continued application of the tool until they are imbedded in the wood as a pronounced angle to the original posi` tion of the metal. Both grip locks may conveniently be made at the same time by means of a suitable press.

It has been found that the locked engagement of the grip sockets to the wooden grip thus provided forms a much more secure and permanent connection in respect to maintaining tightness and prevention of the chattering arising from jarring and severe usage than any of the more or less rounded or conseated snugly j within* and secured together as gripsockets and grip opposite bases connected to the veX forms of projections heretofore employed. The square-cut side edges and ends of the two spurs tend rather to become imbedded the more firmly in the wood of the grip by any expansion of the wood which may occurvfalong their side edges 'and be` tween their ends subsequent to application of the pressure by which the spurs are forced i into place, than to become loose.

I claim:A v y 1. In ahandle of' they typeV described including a bifurcated sheet metal member formed with terminal opposed grip-sockets, a transverse wooden grip and a bolt extending longitudinally through said grip arranged to secure said grip-betweensaid sockets, means for locking said grip in said grip-,sockets comprising` a pair of rectangular spurs struck inwardly from said sockets and imbedded in the adjacent end of the i wooden grip, said spurs being cut uponparallel sidelines and a transverse intermediate line defining the ends of the spurs.

2. In a handle of the type described including arms provided with terminal sheet metal grip-sockets opposed to eachother, a transverse grip formed of wood and having its'ends positioned in said sockets, means for securingy the sockets to the grip to prevent separation -ofthe same, and locking means comprising adj a'cent convergingy spurs struck inwardly from each sheetmetal sockety and compressingv the wood under them.

3. A handle of the type described including arms provided with terminal sheet metal gripsockets opposed to each other, Va transverse wooden grip, a's'ecuring boltextend ing through the sockets andthe grip, and a pairof spurs -struck inwardly from one 'of the sheet metal sockets,

so that they are opposed to each other, their lines of bending are parallel, and theirI edges are substantially radial with respect tothe grips.` o f Iny testimony whereof, Il have subscribed my name.
