To all whom it may concern.-

l'e it known Athat I, REINHOLD BOEKLEN, a citizen of the United States, and aresident of Brooklymin the county of Kings and State of New York, have invented certain new and useful Improvemen ts inHam mers andNail-Drivers, of which the following is a specifica-tion.-

'Ihis invention-hasreference to the class of magnetic hammers or nail drivers forfwhich cIibtzined Letters'Patent August 28, 1860, No. .4 ,7 y

The essential features of thefinvention re- .late to a vertical bar magnetic hammer and .the combination with a m'gnetic hammer or lnetic ham mer with its guide and nail entrance in front. Fig. 2, is a'vertical central. section of the same,showing theposition of thehammer before having attracted a nail but placed to rest nearits head. Fig. 3, is a similar view, showing the nail attracted and rising with the hammer. Fig. 4, is asimilar view, showing the nail entirely picked up'with its shank passing the nail take-0E fork; Fig. 5, is a a poor conducting material.

front View of the same on a smaller scale, the

-nail driver placed for and driving home a nail into overhead work; Fig. 6, is a vertical section of the lower portion of the hammer and guide, placed liable to pick up several nails together. Fig. 7, is a similar view, showing the position of the hammer having picked up a surplus mailand just before the surplus nail being expelled. Fig. 8, is a detached sectional side view of themagnetic hammer and rod when entirely coveredwith lar view of the same. its construction modified; the hammer vmade with a rod of ,poor

conducting material,` and containing in its lower portion a magne-tized hammer. Fig.' l0, is a lateral horizontal'section of the kbottom portion of the hammer guide showing a nail in tangential position with the guide before attracted in full lines and in dotted lines,

Fig. 9,'-is a simithe position after attraction and having entered into the guide.. Figs. 11,12 and'13, aret similar face views o f. the bottom partl of the'- hamrner guide, showing its nail entrance, and

showing the successive positions ofthe nail first in a tangential position andl as soon as' attracted and rising with the-hammer, changing its positionV to a radial vline by contact of'.

its shank withthe side of lthe nail entrance,

and thereby finally' being placed nearly cen-v tral land vertical against, theface of the barn* mer within its guide..

The letter of reference A indicates the magnetic .bar-hammer and rod of thenail driver and B the nail guide" which passes over it readily. ,Said hammer may be made of ,one

rod of steel,'either'only the lower portion or the whole hardened steel and wrought iron upper portion. It is magnetized to attract suitably the size of nail to operate' upon. In some cases said hammer maybe made with only a short magnetized portion on the lower end, and may be of hard cast'iron and inclosed in au outside brass tube, or other poor magnetic conductor and said tube jointed to a brass rod for the remainder portion of the hammer as showniu Fig. 9. '(Said hammer may not have any insulator or poor conductor over any portion thereobr it may have only a short covering ct over the sides ofA thezlower end, which covering maybe of rubber or brass or other'poor, conductor, or the covering ct may cover considerable of the lower portion or the'whole length of the bar or rod as shown in Fig. 8. Generally the top end ofthe hammer`is furnished with a handle C whichisl made weighty and is solidly secured to the top end of the hammer; it may be solid of one metal or may be of an outside suitable metal and made weighty by filling the inner portion with lead as show'n in Fig. 2.'

The nail guideBispreferably of tubular form; it allows the hammer to slide readily therein; its top endlis preferred to h 'ave a pro- .jection or button on it to provide it for a'stop against dropping from the hand of .the operator. It is preferred to be made ofbrass tubing orjother poor magnetic conductor and may be the wholezlength of the same dimension or maybe partly of another diameter as shown in Fig. 6. v l v It is preferred that the hammer have a stop below the bottom end j to stop against the y lmay be provided by means of a projection d from dropping but little with its bottom end of the guide l3,'and that Ia stopbe provided to prevent the hammer to withdraw entirelyfrom the guide B. To provide the stop for the hammer going down unduly, it is made as shown in Figs..l, 2 and 3, bythe bottom end oftbe handle C coming in contact with the top of the guide B., and to provide and stop the hammerfrom withdrawing entirely from the guide Bthere maybe an inward prtu'ecting screw c, at'jthe upper end of thev guide', and -a shoulder i formed on the lower portionof Athe hammer as' shown in Fig'. 2,or the hammer? rodmay have a longitudinal groove e` with a shoulder screw. o, orboth stops of the hammer, engagmgin a slot g made in the sideof theguide B as shown in Fig.YA

4. The bottom endof the guideB'has on one or morev sides of it the tack or nail entrance D,r the hase of whichgcommencesat thebottoned'of the guide'B antl'terminatesat a certain height, closing withapoint. Its dimension in width depends upon the size of the head of the nail operatediupon and is made always alittle larger than said head;V

the height of the opening or entrance Dis made to snit the length of the 'nail to allow it to rise and pass within the guide readily.V

On the oppositeside of the lower portion of the guide to the entranceD, and a little above it-,i is provided Vthe take-oni fork E, which is formed ofv a'vertical fiat spring secured tthe outside of the guide B, and its bottom'- end enters through' an v'opening into the guide and terminates with two prongs" t, one to each side of the nail shank, when raised by the magnetized hammer end, as shown in Fig. 9, sp that by the progress of raising the nail to be driven with the hammer a secondary nail or surplusjh'aving attracted to the shank of the first will come in contact. with its head with the take-oil? fork and 's caused to drop down, or is expelled; or if t e nail isl picked up by the "point it is expelled by,l the take-off E; As soon as the hammer cornes down .just before picking up a new nail, said ltake-oft fork is forcedoutwardv out of the way by contactwith the hammer, as shown in Figx. Said take-off fork may be modified, more than one may be employed audits movements may be to always in time come tiene? ,-itseli' nearly radially andy centrally .into the v 1. In nail fork E, substantially as 'inward for taking oft the surplus nail, but'.

may move outward immediately after and 5 5 may "at all 4times stayoutward. away from the passage of the nail, except at the moment the nailshank passesit for expellingany surplus nail. l l' 4 z For carpet or lotherltoor nailing the ham- 6o mer is made nearly the length of a cane'. By this means the person nailing need not'bend to the floor-'but can nailin almost direct p'o.r 4

'sition. The extrem'ebottom portion,:not` the,...

guide B servesl tli'epur' s't'b'fv locatingand '5'5 resting the guide in-picking-,upthe nail, as

well as in placing e 'he hammerto the spot for` ,the nail to be driven.

l'In placing the implement for pickin up a 4 nail, no care nor time is requiredto ocate shankl of the nail, or that the face of thehead of the' nail be i'n line with the'entrance'l). Av nail' with any parte! its. headtoward the entrance D, will enter said opening vand right guide by beveled sideof the entrance andthe A motion and attraction of the magnetized hammer.

What :I claim as my inventiongs-and desire to secure by Letters Patent, isj-'4 dri-vers and hammers the combination with the magnetized hammer fof a-n'al guide B and a take-o# device. E, substantially as and for the purpose herein set-forth. 85
