I THILL COUPLING. No. 405,108. Patented June 11, 1889.
UNITED STATES PATENT OFFICE.
CIRTHBERT C. MUNROE, OF BOSTON, MASSACHUSETTS.
THlLL-COUPLING.
SPECIFICATION forming part of Letters Patent No. 405,108, dated June 11, 1889.
Application filed March 30, 1889- Serial No. 305,383. (No model.)
To all whom it 11mg concern.-
Be it known that I, OIRTHBERT O. MUNROE, a citizen of Canada, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Thill-Couplings, of which the following, taken in connection with the accompanying drawings, is a specification.
This invention relates to improvements in thill-couplings; and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure 1 represents a plan View of the invention. Fig. 2 represents a longitudinal section on the line X X shown in Fig. 1. Fig. 3 represents a detail plan view of the shaft-iron, and Fig. 4. represents a cross-section on the line Y Y shown in Fig. 2.
Similar letters refer to similar parts wherever they occur on the different parts'of the drawings.
a represents the carriage-axle, as usual, to
which is secured the clasp b, having the downwardly projecting screws b 19, passing through perforations in the yoke c and provided with nuts I) b by means of which the axle, clasp, and yoke are firmly secured together.
d represents the shaft-iron, having a forked end d, to which is secured, or made in one piece with, the ball d, as shown in detail in Fi 3.
E 1 61 are cylindrical journals or trunnions connecting the said ball c with the forked end (1 of the shaft-iron d, as shown in said Fi 3.
l n one piece with the yoke c is made the ball-bearing c', adapted to receive the ball d".
of the shaft-iron, and e is a detachable ballbearing cap adapted to fit against the rear portion of the said shaft-iron ball (1 as shown. Said cap may be made of hard rubber, metal, or other suitable material, without departing from the essence of my invention.
0" c" are guide-ribs on the yoke 0, between which the under side of the cap-piece e is guided, as shown in Fig. 4. The cap e is secured to the yoke c by means of the screwbolt f, passing loosely through a perforation in the cap 6 and screwed through the yoke, which at this place is preferably made of increased thickness, as shown in Figs. 2 and 4. f is a check=nut on the lower projecting end of the screw-bolt f for the purpose of preventing said bolt from working loose.
The screw-bolt f is arranged inclined to the yoke c, as shown in Fig. 2, so as to cause the cap e to be forced against the rear portion of the shaft-iron ball d with a proper frictional resistance, and thus preventing the coupling from rattling while in'use.
By adjusting the position of the inclined screw f the wear on the ball and ball-joint may be taken up from time to time as may be needed to prevent rattling and to obtain the necessary frictional resistance between the ball and its ball-bearing.
The invention is very simple in construction, is composed of very few parts, and by its use a proper connection is established between the shaft-iron and the axle and all rattling and consequent unnecessary wear of the jointed parts prevented.
Having thus fully described the nature, construction, and operation of my invention, I
wish to secure by Letters Patent, and claim-
