Be it'known that I, Jonssc 'ins, Jr., a

of the United States, and a resident invented certain newand useful Improve- This invention relates to an improved torm ofispring fastening device for electrical conductors,

particularly adapted for application t-oa dry battery, although the device may be used many connection in which is found applicable.

If an ordinary. binding post is me ely fastened to a dry battery, the post will project outwardly from the side ofthebattery and when a number of cellsare used in'conjunction,-the binding-post of one cell is liable to contact with that of anotherand ruin. the batteries.

The projecting posts are also aptto be broken ofl in packing and"inshipment.

drawin which is a perspective'view oi afdeodying 'the invention.

My. improved fastening device is prefeljf as for instance, 'metallic' wire,

a single piece 'ofmate or it-may' be made out of several pieces, if desired, and I am notto be com rised of a single piece'ofwire.

understood a s hunting the invention to a fastening device q ofmaterial, for other forms'Qqf 'resilient e fastening device comprises broadly two opposing normally separated members,

and a retaining resistant portion of suitable projecting toward theop'po'site mem adapted'to co-act' therewith to firmly shape ber an clamp a'conduct'or in defined position when said members are forced into operative "re-' 'latio'nshi v Ill'Olt er'to construct two opposing normally separated members, the piece of: ire.

adapted to be fixed in stationary position,

while the opposing member, comprising g thc legs. B is acapted to be forced out of its normal position .toward the body member,

from which it-tends to separate. under the gretraetiy'e force of the spring, d a conductor l K to be firmly. rlppediganc thus enablin clamped in defined posit on riv enyrhe spring member B and the stationai'yare sistant -or retannng portion com )rrsmg the bent portions '0. of .the legs or body member,- f, I The retaining portion Q of the body members'forms a stationary resistant member,- so

constructedand shaped that a conductor is ripped in defined osition in such withdrawn in a transverse direction while under the influence of the pressure of the spring.

I havefound that a substantially V-shaped retaining portion G, forming the resistant .member fulfils the objects sought.

- when] comb'n ed with the other cooperating elements of my improved fastening device. 7

I mean by a V-shaped portion, a part having diverging sides and having the general con-L formation of a Vso that a conductorof suitable size I -V will make. contact at at least two tangen when inserted in the angle of the tial points in the V.

, As shown, the apex and is adapted to co-act With-said spring member toclamp a conductor defined pos1t1on therein when said members are forced -into operative relationship.

,The fastening device in accordance with this invention is intended to be secured d1- rectly to the outer shell of the battery. A

Prefierably the angles at thebends offthe retain-- wire are less 7 than a I as nearly as possible of the angle of there-I slstant member V project's upward from the bodyjmember A toward th'e spring' member Since a plurality are usually used dry battery is represented at I having the I the body member of the fastening device are bent :atan angle to the general direction of the body member and adapted to be se the fastening device on f able means may 40.

The zinc shell Q containsthe composite parts of the batteryand forms one of the, elemen'tsthereis fastened to the .zinc shell' Q outside of the 'upperedg'e, thus locating the other'com the fastening device subponent parts of the tantially within the area described by outer periphery of the shell.

vMy p culiar construction is especially adaptedto the construction of a. dry battery,-s o that no part of the post projects outside of the outer periphery of the cell'.- It is much. easier to manipulate of the fastening device,

of binding posttop -of the battery than at the side, since the pressure exerted to open the fastening device is downward instead of sidewise. The utility of the invention .isapparen-t in packing the batteries for shipment and'npreventing the con nection on one battery touching the connection on another battery] where a pluralay of batteries are-v-used side by side, This latter consideration is important, because are allowed to touch, I circuited and ruined. ,jv of batteries of this type in one installation, it is eirtre'mely important that care betaken to prevent the connections from coming in con-- if the c'o1'mect-ionsj S the battery. is short tact." v
