' l'O ALL Wl-IOM l'l MAY CONOER:'

Bc it known that I, F. MORSE, of New Haven, in the county of New Haven, and State of Connecticut, have invented a new Inilprovmnen't in lloint for Ca-rrl'age-Braces; and I do hereby declaro the following, when taken in con noction with thc'accompnnying (ira-wings and thelettersofreference marked thereon, to he a full, clear, and exact description of the same, and which said drawings vconstitute partof this specification, and represent, irl-'- l Figure l, a sifie'ew.

This invention relates particularly to an Aimprovement thejoint used forl supporting carriage-tops, and

known to the trade as stump joint; yet the novel construction of 'this jointfrenders it applicable to otherv places and uses, and the invention consists in anv internal-cone-seat, combined with an external cone, which forms what may h etormed a dove-tail hinge-joint. 4 I 4 4 i i In order to the clear understanding otv my invention; 'i will proceed todcscribe thcsmn'e, as illustrated in the accompanying drawings. y i l I .i l l i i A is the one part, B the other part, formedi'so as Ato he welded to'fthc bracesor` so as to be attached to whatever isi to be applied tothe joint or hinge.- The one part A has .an eur, C, formeclupon one end, equal to u itbout one-helf the thickness of the piece A, and conical, diminishing from the cen'tre outward. Upon the upper around the cone D, and forming e corresponding conical recess,

seen indig. 4, so as to leavela shoulder, a, entirely surface pf-th conical ear C is formed a'reversc cone,`D, as

d, betwen the cone D and the part A, :ill as "seen in tig. 4. The other part B has a. corresponding ear, E,' formed as seen in iig. 5. In its centre a cavitgr is formed corresponding to the cone. I) on the other port, and its outer surface, so as to till und fitin the recess d, as seen infig..l 3f The recess d should be a. little lnarrower ai: the base than at thetop, and the cone D may, if preferred, -extend through the ear E. 'Thcend ofthe part B, atf, is formell to receive and-fit closely the enr' C, as seen in figs. 3 and 5. The two'parts thus formed are set together ns seenin igsrl, 2, and 3, and 'when so set the internal cone, combined with the external conical surfaces, forms'a. strong and perfect joint, relieving save that of simply holding thel two parts together, the entire wear occasioned oy the the pivot fnom all strain,

ng td'lthe fullestextcnt all tendency movement or operation of the joint being upon the conical surfaces, resisti to rattle or strain. I i I i I- do not broadly claim a .jointhaving upon oneear a cone and the other a corresponding recess, as such was patented to me'Aprl 23,1867.; butwhat I do claim as new and useful, anddesire to secure by Letters Patent,is.- -y

The cone D, formed 'nponan inverted conical ear, EA, provided with annternal conical seat upon the other part, to cori` substantially as herein set forth. y i

C, on the one part., combined with a corresponding ear, espond to the conci),= the whole constructed F. B. MGRSE.
