` "WILLAM"CLEV'13IJAND, o3`- LAWRENCE; MASSACHUSETTS, ASSIGNon 'To f ltEIIllZlSEIJF ANDLJAMESU-SWAN, OF SEYMOUR, CONNEOTICUI.'A
Letters Patent N. 112,419,da1;ei1mavrch 7,1871,
IMPROVEMENT IN BxT-BRAeEs The Schedulereferxed 'colin thesevLette'rs Patent and-making part of the same.
:To all-whom it mq/y concern: I y
l Be it'known that I, WILLIAM CLEyEnANn, of
Lawrence, in `the eountyofEssex and State'of Mas` sachusetts, have invented a new Improvement in Bit-4 Brace; and I dohereby declare the following, when taken `in 1connection with the -accompanying drawing Tand the letters of reference (marked thereon, to be a full, clear, and exact description of the same,xand
which `said drawing constitutespart of this specificaftion, and represents in-f- Figure l, a side view;`-
`Figure 2, a vertical ,centraly section; "and, in
"1 Figure 3, the inyenton'as app'liedtootherinstru-` niente--V l i `This invention relatesto an improvementin lthe A,head `of hitbraces, but-is applicable to the handles or lheadsof other t`oo1s,in :which it is desirable ltoconstruct the head seas to :permit 'the ,body toturn 'while the `head remainsf stationary,` the object, `being `toi'orin the fhead, piyot, and bodyf all of wood, and .without the use of metal rivets, as heretofore'used; in
these articles; andtheinventionconsistsin forming *a headedstud-upon one part, and a chambered recess,`
corresponding yto the form ofj the stud, infthe other `part; thenfsteamingthe ehambered portion -until-ina -state to he'drivenover the headed stud, and when t driven over, the wood will shrink and close around `the stud, 'securing"the,partst gether, yet allowing their `free action independent'of eachother. 'o
A is the body andlB the head 0f a' bit-brace. on" the head Iforma stud a, with anenlarg'ementdnpon the end of thestudat'a little 'distance from thehead, as seen in g. 2,'aud in the body I form a chambered recess corresponding to the stud a and its enlargement d, asseen in fig. '2. I then' steam'the -body until 'it is in a state to be driven over the enlargement ofthe stud, and force the. body onto the stud until the' enlargement passes into'the chambe1 ,fas denoted -iu ijg.l2; then the body, in drying, shrinks around thestud so as to secure the two parts together, and yet allow the body to turn freely on the stud as a bearing.
In lthisfconstruction the. usual central. metallic device 's avoided, amueh cheaperarticle produced, and
better, in that it cannot by any possibility get outof order.
' The same invention may beV applied; to other han-' the same'manner; as denoted in fig. ,3;
I claim asn1y'invention- I .The head B and body A, united by the stud a d,
dles,as for awls, screw-drivers, 85o., and :in identically ,set into a corresponding recess in the body A, and so asto turn freely therein, substantially as and for'the vpurpose herein set-forth., l WILLIAM CLEVELAND,
