Specification of Letters Patent. Patented Aug. 30, 1921.

Application filed September 13, 1920. Serial No. 409,853.

T all whom it may concern a citizen of the United States, residing at Whitneyville, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Brace Heads; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the-characters of reference marked thereon, to be a full, clear,

and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1, a view in vertical central sec-.

tion of a brace head embodying my invention, and shown as applied to the upper end of a brace crank shown in elevation and broken away.

Fig. 2, a reverse planview of the brace head with the crank in transverse section on the line 2-2 of Fig. 1.

Fig. 3, a view, partly in elevation and partly in section, showing the head after the parts are assembled but before they are locked together.

Fig. 4, a detached sectional view of the body of the head, showing its interior chamber.

Fig. 5, a detached view, partly in elevation and partly in section, of the flanged bushing of the head.

Fig. 6, a plan view thereof.

Fig. 7 a detached view, partly in elevation and partly in vertical sectlon, of the coupling-sleeve prior to being upset.

Fig. 8, a plan view thereof.

Fig. 9, a View, partly in elevation and of the split tails of construction and combination of Be it known that I, EDWIN W. BULLARD,

parts, as will be hereafter described and pointed out in the claim.

In carrying out my invention as herein shown, I form the wooden body 13 of the head with a centrally-arranged circular chamber 14: receiving a bearing-cup 15 having a conical end 16 and an upsetting flange 17, the lower face of which is concaved.

This cup receives an integral bearing-cone 18 formed upon the upper end of the bracecrank 19 which has near its upper end a circumferential groove 20 for the partial reception of a resilient split retaining ring 21, also partially entering a bead 22 formed at the lower end of a shaped coupling-sleeve 23 furnished above its median line with a circumferential flange 24 and with a series of retaining-fingers 25," the said flange 24 forming a seat for the corner of a flanged bushing 26 fitted within the chamber 14 of 1ng out of the bottom of the chamber 14 in the body 13. When the sleeve 23 reaches its home position the split ring 21 sufliciently contracts to partly'enter the groove 20 in the brace crank 19, whereby the sleeve is held against longitudinal displacement with respect to the crank 19 but remains free to rotate thereupon with the body 13 and the several parts carried thereby.

I claim:

A brace head having a chambered body, a bearing-cup located inthe chamber thereof and formed with a cone-bearing and a flaring assembling flange, a crank having a cone-shaped upper end which enters the said cone-bearing, a bushing located-within the open end of the chamber in the body, an assembling-sleeve encircling the crank, en-

tering the said bushing and formed at its In testimony whereof, I have signed this upper end With a series of locking-fingers specification in the presence of two subturned outwardly upon the flange of the scribing witnesses. cone-bearing for locking the parts together, I EDWVIN W BULLARD.
