To all ro/tom may con-(gem:

Befit known that -I, lYrnnrAM lVI LIA-Ms, a subject ofthe King of Great Bri-tai-n and a resident of v ailway Park,;-M urrunibeena, inthe State of Victoria, Australia, have invented new and useful Improvements in ()arpenters Hammers, of which the following is a specification. I e 7 This invention relates to improvements in c'aiipen'ters hammers and refers especially to hammers having a claw for pulling nails out or wood orthe like. e V

a is customary to provide'clawhammers with a deep eyefor the handle and 'to; form a round face on one side and a curved n'ail pulling claw on the other side of the eye It has been proposed to provide the eyeof the hammer with an auxiliary claw-or claws arranged more or less parallel withand converging in the same direction as the nai-l PEIlIings o The'object of the present invention is to provide 7 exceedingly simple ;andeflicient means whereby a :powertul leyerage canjfbe olitained on a longnail withoutany liabil-V layer the nail be eoming-disengaged from or slipping out of engagement with the hammer, even when it has been partially extracted or when the head is at-a distance froin'thedrivenportion I Z g 7 I accomplish the above-mentioned object jprbviding the hammer near the top of the eye vvith awsr01: engagingthe head; or shank-of a nail and havingthe sides-theree f ce'rivefging .in an opposite direction tothe claw, whereby when a nail partially withdrawn by 'the claw, the said head can' be inserted and held in 'thesaid engaging jawsgsofthat the fulcrum point is altered and allows the nail'to be extracted without necessitatingthe tilting of the hammer to such an extent as -to occasion material loss ofle vem'ge. I p i In "order that the invention may ;be readily understood, reference will now be hadto'the accompanying :sheet of explana tory drawings wherein I Figure 1 is a view in perspective of a hammer constructed in accordance with the present invention. In this view the ham mer is shown 7 in position drawing a long ii'ail froin'a piecedfwoodp Figures is a view in sectional elevation taken on the plane 2-2 of Figure 1 and shows portion of the claw and head of the hammer.

Figure 3 is a View in sectional side ele vation taken on the dotted line 33 of Fig:

Figures 4:, 5, 6,7 and .8 are views in iperspective ofpart of a hammer showing furfully dether modificationsof the invention;

Figure 9 is a view in sectional side elevationof part of the hammer. s

Figure 10 is a view in sectional elevation talz-en-on-the plane 10 10 of Figure 8.

In these drawings-like characters ofreferenceindicate-thesameorcorresponding j parts in the different views and-the letter a'designates the eyeof a'carpenters hammer having a face Z on'one side and -a rearwardly divergingwclaw 0 on the other side thereof of Ordinarydesign; e v

The-top'of the eye 'is-pro'vided' with means for engagingthe head or jpor tion o'fa nail 0 adjacent to the'head whereby when a long nailis partially drawnthe hammer can "be tilted so that-the head or shankrof the partiallydrawn nail is'gripped by 'the said en'- gaging means whereby a second pull can be had on-the-na'il and the outer face of the clawactsasa f-ulcrumfi I 1 Theme'ans 'on 'the top of 'theeye of the hammer for engaging the head-or shank of the nail may vary in J construction and in the drawings several different forms of engaging means have been illustrated.

I In Figures 1,2, and 3the engaging means on the upper part of the "eye'comprise a pair of rearwardly convergingj aws cl formed longitudinally on theeye" at=the rear of'a hole-e in the said eye. 1

When a nail ispulle'd halfway or fora portion of its length from apiece of wood f the head will be disposed as shown iirclotted lines at =9 in Figure 1 and when the shank is dise'ngaged from the claw c andthe head inserted in-the hole 6 itmay be'passed betweenithe jaws d in which position the ends 1 the claw of the hammer nice of the piece of wood from being drawn. 5 1, 2, and 3 of the drawings the ned by pressing up portions .art of the eye of the hammer s of the jaws converge as they U "rom the hole 0. The converging it es of the jaws enable nails of different iichness or gauge to be gripped and retained in position when the second pull is obtained on the nail.

The hole 6 may extend right through the ey and handle of the hammer as shown in Figure 3 of the drawings so that when an extra long nail is to be drawn it may be drawn in three stages, first by means of the claw c, secondly by means of the claw c and the jaw d, and the third operation by passing the head of the nail through the hole 0 and again pulling on the handle and using the outer face of the claw as a fulcrum.

In the modification shown in Figure 4 of the drawings the jaw (Z is formed on top of the eye and is of suf'ficient dimensions to engage different sizes of nails.

In Figure 5 of the drawings the jaws d are shown rivetted to the top of the eye of the hammer and in Figure 6 of the draw ings, the jaws are formed with downwardly projecting lugs 71 which are secured to the sides of the eye by means of rivets or screws 9'. If preferred the jaws d shown in Figure 5 can be formed integrally with the eye.

The jaws shown in Figures 1 to 6 have their converging sides undercut to provide clearance for the head of a nail to be moved rearwardly therebetween to enable it to be retained firmly between the jaws when the nail is being drawn by the claw and jaws. Moreover the jaws shown in the above-mentioned figures are opened at both ends but it will be obvious that the rear or narrower end may be made closed.

In Figure 7 of the drawings the top of the eye is formed with a converging slot which terminates in a hole a formed in the said eye. The wooden handle immediately below the sides of the converging slot 70 is cut away to form a jaw which is adapted to engage the shank of the head near the nail when a second pull is desired to be had on the nail.

In Figure 8 of the drawings the top part of the eye is shown extending along the handle of the hammer as at Z to accommodate an auxiliary engaging means is for the nail and constructed somewhat as shown in Figure 7 of the drawings.

lVhen two auxiliary slots or pair of engaging members is are provided on the eye they can be made uniform in size or one can be made larger than the other.

Figure 9 is a View in longitudinal section of part of Figure 8 and clearly shows the cut away portion of the handle beneath the edges of the said slots.

Figure 10 which is a cross sectional View of the eye of the hammer on the plane l010 of Figure 8 also shows portion of the handle cut away to provide clearance for the head of a nail.

In an alternative construction the top part of the eye can be formed with an upwardly extending flange m which forms a socket and is adapted to surround the converging sides of the jaws d or slots 70' whereby the second grip may be obtained on the head of the nail. The upward projecting flange m is shown in Figures 6, 8, and 9 and the said flange m can be used independently of or in conjunction with the jaws cl or the slot is.

lVhen the head of a driven nail is at some distance from the piece of wood from which it is to be extracted, the head thereof is engaged by the auxiliary engaging means on the eye, and the hammer is tilted by pulling on the handle thereof. The curved face of the outer claw rolls over the surface of the piece of wood and acts as a fulcrum to enable a powerful leverage to be obtained and the nail to be easily extracted.

lVhen the nail is driven nearly home, the outer claw can be used to partially extract it and then the auxiliary claw or engaging means can be used to hold the head of the nail while the operation is being completed.

The invention is simple in construction and in use will be found thoroughly eflicient for the purpose for which it has been devised.
