To all whom Iii-may concern: bar and on a line below the castings B are at- Be it known that I, CHARLES E. GOULD, a tached castings having side projections, citizen of the United States of America, residwithapertures which register with the apering at Fremont, in the county of Newaygo' and tures in the castings above, the apertures be- 5 State of Michigan,have invented certain new ing connected by apertures through the crossand useful Improvements in a Self-Supportbar so that both castings are secured to the ing Knuckle to be Used in the Construction of cross-bar by the same bolts.

The ends of this bar or rave are vided with depending bearing-surfaces and a rigidly bolted to the runner, and when the central recess which engage a casting shaped parts of the knuckle-joint are placed in posito receive the same, the latter casting being tion the horizontal portion of the bar or rave 30 secured to the upper edge of the runner, the bears upon the casting B, thus holding the parts being held in place by a bar or rave, parts O and D securely in position by fricwhich is bolted at its ends to the runner, all tional contact. Then the parts are thus conas will be hereinafter fully set forth and parnected the complementary bearing-surfaces ticularly pointed out in the claim. of the parts C and D are in engagement with 5 In the accompanying drawings, forming each other, so that they can rock in the direcpart of this specification, Figure l is a pertion'of the runner and the bar or rave E will spective View showing the parts in position prevent displacement, I for use.

but as far as I am aware the castings or fixtures heretofore used have been connected by bolts which pass through slots or elongated openings.
I am also aware that runners have been connected to the cross-bar so as to have a sliding movement thereon, the parts being held together and against vertical displacement by means of long bolts placed at the front and rear of the knee and connected to a bar which extends over the cross-bar and is attached to the runner.
I am also aware that it has been proposed to connect the runners and cross-bar by a joint which is coupled by means of a transverse bolt.
\Vhat I claim as new, and desire to secure by Letters Patent, is
A knuckle-joint for sled knees consisting of castings B and 0 having convex recesses to provide bearing surfaces having side walls and projections with apertures which register with each other so that both castings are secured to the cross-bar by the same bolts, a casting D having side bearing surfaces and a central web 01 which are complementary to the bearing surfaces and recesses of the casting 0 attached to the under side of the cross-bar, and a bar or rave E having a horizontal portion which engages with the convex bearing surface of the casting Bfisecured to the upper side of the cross-bar, the ends of the bar or rave being attached to the runner, substantially as shown, whereby the bar'or rave holds the parts in engagement with each other, for the purpose set forth.
In testimony whereof I affix my signature in presence of two Witnesses.
