To all whom may concern:
Be it known thee l, liens-en J. 'l frnnn'rr, a citizen of the United Shh-ates end residing in Milwaukee. in the connly of liiilwsulree and State of llisconsin. have invented certain new and useful improvements in Safety- Loclrs for ll nnnnerllnndles, of which the following is a specification.
invci'ition rchitcs to safety devices for use in conneczion with sledges nd has pariic'l'wr reference to a novel loci: by means of he handle is securely held in place in ti e he.
ll" is not nnconnnon in the use of heavy hammers or or the head i cC m separated from he handle, many times causing serious injur to fellow workmen. This a hazard which has been sought to be overcome in many Ways without msrlred success.
An object in the construction of such a device should he to provide holding means for the handle which shall he independent of ihe head itself and which shall not rely on the .iieningzs entering the material coznposinn the handle. Any fiistenings which rely for their holding power on their entering engegenienl with the Wood of the haninier handle are insecure and tend to weaken the hand o ice contemplates the use of a pair of wedging clumps which shall not to grasp the l'ninnncr handle at ii. point close to the heed nod clamp the shine in such manner that separation from the head isiinpossible. Such a fastening; device is so,loc-.ited as to be onlfiof the \vc n'cznmot become out of order and is very easily applied.
The invention will be more readily understood by referring to. the accompanying drawings. wherein, Figure 1' is 3 side elevation of o hannner constructed in accord openings accommodating rivets 13, by meansof which. a ferrule or clamp ii, is secured to the. inside face of the head. This clamping member is provided Witghn central opening l5, which opening near one face of the clamp is enlarged as at 16, thus providing a. shoulder 1?, against which the flanges l8, of the handle clamps 19, 20, may engage. These clamps are semi-circular in cross section and Wedge-shaped in longitudinal section being cdopced is fit snugly the portion oflzhe him die 21, next to she hammer head. As is usual, the aperture through the hammer head is of slighely reduced or. use seciion near the middle portion the handle tapered at the point Where is passes through head. handle enlsrg o in completely fill the shown in Fig. This pro .iy enlarged portion on she e point it enters the vides a hammer on being seated in the heed the head, which poini is reduced-in size at, ii
short disnnice rearward of the handle. The wedge-shaped clamping members engage this slightenlargement' and due to the clamping action hold the handle securely against accidental removal,
T he application of the clcinpirq device u may be as follows: l rior to insert. the handle in the head, the clamping member id, 1s placed on the handle. Ellen the wedge shaped members 19 are placed in posision elmii point on the reduced portion of the handle. lhe head is then. located on the handle, whereupon the clamping inci'nhcr up into engagement with the head s." of"? rivets 13 applied. This serves to rigidly unite the clamping member 1% to the iced and to wedge the semi-circular members on the handle. Accidental removal of the hen .dle is thereafter impossible as even though ill the handle'should become loosened in the surrounding said handle and secured to said head, and a. pair of wedge-shaped clamps engaging said ring and cooperating Vlfill. the surface of said handle whereby to. prevcnl:
the accidental removal of said handle, shin .stantially as described.
2. In a hammer, the combination oil c. head, a. ring rigldly secured to said head, said ring havingisn undercut aperture therehead, said hanrlle having a wedgefihapm through, .ziid sicking w th an 6- sea zed in the undeicuif. Iedess in said aperture 111 the head, a han'die seated 1n sand gampmg gang, substantmlly as descrlbed.
