HANS CHRISTIAN OHLSEN, OF CINCINNATI, CHIC, ASSIGNOR TO HAYDOCK, OF SAME PLACE.

FIFTH-WHEEL.

SPECIFICATION forming part of Letters Patent No. 283,139, dated August 14, 1883.

Application filed'January 17, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, HANS Onnrsrmn OHLSEN, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Vehicles, of which thefollowing is a specification.

My invention relates to a construction of the king-bolt, head-block plate, &c.', which combine simplicity and cheapness with security.

In the accompanying drawings, Figure 1 is an under side view of the head-blockand its accessories. Fig. 2 is a front elevation thereof. Fig. 3 is a fore-and-aft section of the fifth wheel and adjuncts. Fig. 4 is'a perspective view of the head-block plate and of the upper member of the fifth-wheel, together with portions of the head-block and of the perches.

Fig. 5 is a perspective view of my improved king-bolt and of themiddle portionof the head-block plate viewed from below. Fig. 6

is vertical section of the head-block plate on the line w m, Fig. 5. V

The following parts may be of the repre sented or of any customary or suitable construction, to wit: front wheels, A, axle B, axlebed 0, lower members, D, and upper member, E, of fifth-wheehspring and spring-bar F G, body-loops H, body I, perches J, stay-brace or guard-iron K, clips L, and screws, bolts, or

rivets M. I r

My head-block plate N has the customary perforated fore and aft lugs, n, for the springclip, perforations n for the rivets which fasten the upper member of the fifth-wheel, and perforations n for the screws which attach said plate to the head-block. From the rear edge of plate N project as many lugs O as there are perches, whose forward extremities are attached to said lugs by rivets that pass the -1nanner shown, terminates in an eye, It,

through orifices in the latter. Each lug has two lips, 0, which embrace the perches on the sides thereof.

e areorifices in the upper member of the fifth-wheel, for rivets which attach it tothe perches, and e. is an orifice for the rivet which attaches to saidupper member the rear extremity of the stay-brace or guard-iron K, which, extending forward and downward in ,which receives a stud, 19, that extends downward from the plate 1?, which is perforated for the screw-threaded clip extensions (1 of my safety king-b olt Q. The extensions q and stud 1) receive nuts- (See Figs. 2, 3, and 5.)

From the under side of the head-block plate project two lugs, R, whose opposing surfaces are undercut, as shown at r in Fig. 6, to receive sponding dovetail projections, g, from the kingbolt, which having been inserted with its projections directed fore and aft, (see Fig. 5,) and then turned one quarter around, and the parts being bolted together, as shown in Fig. 3, the king-bolt becomes securely locked in position without at all interfering with the restricted rotations of the king-bolt within the headblock,.which take place when the vehicle is traversing a curve. A prolongation, g, from the king-bolt, extending upward through the head-block, 'and through the lower limb of the body-spring, is riveted in a countersink in the latter, so as to bind all members of the fifthwheel and their adjuncts firmly together, and also so as to afford complete security against the droppingout ordislodgment of the kingbolt.

I claim as new and of my invention- N, having recessed socket R, and the kingbolt Q, having lateral projections q to fit in the socket, head-block, as set forth.

' 2. A king-bolt for fifth-wheels, formed with screw-threaded clip-extensions q q, dovetail lateral projections 11 f, and prolongation q, as set forth.

3. A. head-block plate for fifth-wheels, formed with fore and aft lugs, n n, perforations n n and n'n, lugs O O for the perches, hav- I ing lips 0 0 and perforations 0 0, and the lugs plate, as set forth. j

In testimony of which invention I hereunto set my hand.
