KING-BOLT FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 343,428, dated .Tune 8, 1886.

Application filed October 28, 1885. Serial No. 181,152. (No model.)

To all whom. it may concern:

Beit known that I, WILLIAM F. BIDWELL, of the city of Troy, county of Rensselaer, State of New York, have invented a new and useful Improvement in King-Bolts for Vehicles, of which the following is a specication.

My invention relates to king-bolts and their connections with the head-block and front axle of vehicles, the object and purposes of my invention being to make them secure in their connection and noiseless in their action.

Accompanying this specification, to form a part it, there is a sheet ot' drawings containing five gures illustrating my invention, with the same designation of its parts by letter-reference used in all of them. Of these illustrations, Figure 1 is a perspective of the head-block, front axle, fifth-wheel, and reach of avehicle with my improvedkingbolt connected therewith. Fig. 2 is a crosssection taken through the king-bolt, headblock, front axle, anda part of the reach. Fig. 3 is a perspective of the det-ached king-bolt, journalbox, and mechanism for connecting said journal-box with the front axle. Fig. .4 is a perspective of a sleeve adapted to be passed down: over the before-named journal-box to rest on a shoulder formed thereon, said sleeve being adapted to be connected with the kingbolt. Fig. 5 shows the king-bolt made with a square shoulder immediately beneath the head, adapted to enter a square socket in the sleeve to connect the latter and bolt, to prevent the bolt from turning in the sleeve.

The several parts of a vehicle and those constituting my invention are designated by letter-reference, and the function of the parts is described, as follows:

The letter H indicates the head-block, S the spring, and K the clips connecting said spring and headblock.

The letter A designates the front axle, R the reach, and W the fth-wheel, the former constituting the ordinary and well-known parts of a vehicle.

The letter J designates the king-bolt journal-box, and s a shoulder made thereon by reducing its exterior diameter at a; C, a clip 'formed on the journal-box to attach the latter to the front axle.

The letter S2 indicates a sleeve adapted to be passed down over the journal-box J, so as to rest on the shoulder s, and b a bar connected with said sleeve and adapted to attach it to the head-block by means of bolts and nuts a a.

The letter B designates a brace connecting the sleeve Si2 With the reach R by means of a bolt, b2,- and the letter M indicates4 the kingboltproper, made with the square part m just below the head h', said square part of the bolt being adapted to iitinto the square upper end, mi, of the sleeve S2, so as to connect thelatter and the bolt and prevent its turning therein, and n2 indicates the lower threaded end of the -bolt and asecuring-nut. The exterior of the journal-box J is made to havea smaller diameter at a than at a2, with the shoulder s arranged between said parts a and ai., The upper part of this king-bolt journal-box exterior above the shoulder s is adapted to receive the sleeve S2, so that the latter can be passed down over it with the lower end of the sleeve resting on the shoulder with the journal-box J free to turn thereon. The king-bolt M is constructed to pass down through the sleeve SL and `journal-boxJ and be secured as thus placed by means of a head, h', on the upper end and a thread and nut, a2, at the lower end of said bolt. The upper end ofthe king-bolt,where immediately beneath the head h, is made square,

as designated at m', and the upper end of the sleeve S`l is also made correspondingly square at mso as to secure the square part of the bolt thereat, so that when the bolt is inserted within the said sleeve and journal-box J and secured therein the sleeve and bolt cannot turn. The journal-box'J being secured to the front axle, as the latter pivots to move to one side or the other in changing' the direction of the vehicle the king-bolt and sleeve S2 do not turn, but the j ournal-box J turns on the bolt M, and also where within the sleeve SL at a', above the shoulder s. As thus made, the turning parts of the vehicle have two vertical bearings on which to move, with their surfaces so housed in that grit and dirt cannot reach them, with the parts so arranged that they have one transverse bearing-fthe shoulder s and the vertical bearings of the journal-box J where its part a is within the sleeve S2 and where on the kingbolt. Thus the chances of wearing away are much reduced, and the noise produced by the engagement of loosel5r connected parts is avoided.

Having thus described my invention, what elain'nand desire to secure by Letters Patent, 1s-

1. The combination ol the sleeve Si, eonstructed with the square socket 'mi at its npper end, and the bar I, adapted to connect it with the head-bleek, thejouxfnalbox J,1nade with the reduced exterior a', shoulder s, and adapted to att-ach to the front axle, and the king-bolt M, having thellead h', the threaded end and nut n, and made with the interior square part, al1/,immediately beneath the head, all substantially as and for the purposes set forth.

2. The combination of the sleeve Sienn- Signed at Troy, New York, this 18th day of July, 1885, and in the presence ofthe two Wit- 3o nesses whose names are hereto Written.

WILLIAM F. BIDWELL.
