AXLE-CENTER.

SPECIFICATION forming part of Letters Patent No. 710,921, dated October '7 1902.

Application filed June 4, 1902. Serial No. 110,193. (No modeld To It whom it may concern:

Be it known that I, CHARLES T. MCCUE, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Axle-Centers, of which the following is a specification.

The invention relates to axles, and more particularlyto the central portion of the axle, and in the present device is shown in connection with the front axle of a vehicle, which ordinarily is a steering-axle, and is provided with a king-bolt upon which said axle is oscillated.

The objects of the invention are to provide an axle-center the main body portion of which is composed of metal and is so formed thata wooden seat or block may be securely held in position on one side thereof, the holding means being so arranged that none of the parts project below the line of the main body portion.

A further object is to provide a king-bolt integral with the main body portion and so arranged that the reach-lugcooperating with said king-bolt will bring little or no strain upon the king-bolt. In fact, one of the material objects of the present invention is to so arrange the reach parts connected with the front axle member that all strains will be transmitted between said connecting parts directly through the body portion of the axle, while the king-bolt serves merely as akeeper to maintain the proper position of the parts.

Referring to the drawings, Figure 1 is a view in side elevation of an axle embodying the invention. Fig. 2 is aplan view showing the under side of the axle. Fig. isa crosssectional view through the axle, king-bolt, and appurtenant parts. Fig. 4 is across-sectional view on the line .99 a; of Fig. 1.

Referring to the drawings, the numeral 1 denotes the main body portion of the axle, which is preferably formed of metal and recessed, as at 2, to form a seat for the block 3, which is preferably of wood or may be made of any other material. This block is made to conform at its under side to the recess 2 and fits nicelytherein. Upon the main axle-body 1 are lugs a 5, which are arranged on opposite sides of the axle and perforated to receive the bolts of the straps 6 7, which bolts receive the usual nuts that hold the block 3 in proper position within the recess 2. These straps are secured in place by nuts 8, and the lugs are so formed with relation to the main body portion 1 that none of the fastening devices project below the lower line of said body portion. These lugs may be formed up in any desired manner, and while they are preferably forged out of the stock of the body portion 1 they may be planted thereon and brazed or secured in any suitable manner. There is a certain advantage in arranging the lugs at the side of the axle memberand forming them up integral therewith, and it is to be noted that these lugs are located well up on the side of the axle, so that all connecting parts are above the lower line .of the axle member. This form of lug provides avery rigid attachment for the straps and permits the greatest possible amount of clearance below the axle, which is all-essential to the modern vehicles using the suspension type of wheel. This lug construction also obviates the tendency of cramp between thestrap-bolts of the strap 6 7 and cooperating nuts 8 when the latter are screwed to position. In ordinary constructions, where a plate is used below the axle member, it is often difficult to secure proper adjustment of the nuts on the strap-bolts, owing to the fact that the plate is tilted from undue tension upon either end.

Centrally of the axle member and in the usual position is a king-bolt 9, which is formed integral with the body portion and surrounded by a socket 10. As shown in the drawings, this socket tapers from the lower to the upper end and forms what may be called a cone-socket surrounding the king-bolt.

The numeral 11 denotes the reach-bracket, which is suitably secured to a reach member (not shown) and maintains the properrelative position between the front and rear axles of the vehicle. This reach-bracket is bored to fit upon the king-bolt 9 and conforms in general shape to the socket 10, within which it projects, while a nut or equivalent means 12 prevents disengagement of the parts. The advantages of such a construction as this are obvious, as the conical reach bracket fits within the socket surrounding the king-bolt, and strains which exist between the parts are taken up between the main partsthe body portion of the axle and the reach-bracketand thus little or no strain is transmitted to the king-bolt, which would tend to fracture or bend it out of alinement. In fact, the kingbolt serves practically as a bolster and retainer for the interengaging parts, While the tapered socket and conical reach-bracket form the real bearing and pivot for the front axle.

While the invention herein has been specifically described, as shown, it is obvious that numerous modifications might be made without departing from the spirit of the invention, which contemplates the formation of an axle having a main metallic body portion recessed to receive a Wooden block or seat and provided with retaining means for holding the parts together and with or Without this arrangement a king-bolt formed integral with the body portion of the axle and so arranged as to serve as a retainer for the bearing portion of the axle and its cooperating reach-bracket.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In combination, an axle comprising a main axle and removable portion, perforated lugs formed integral with the main axle, straps provided with threaded ends embracing the removable portion and passing through the perforated lugs, and means cooperating with said lugs and threaded ends for securing the parts in position.

2. In combination, an axle comprising a main axle and removable part,perforated lugs formed integral with the main axle and located above the lower line of said axle, strapbolts encircling the removable portion and embraced by the lugs, and means cooperating with said strap-bolts and lugs for securing the parts.

3. In combination in an axle center, a main body portion provided with asocket, a king-bolt projecting from said socket, a reachbracket arranged Within the socket and surrounding the king-bolt, and means for holding the parts in position.

4. In combination with an axle having a main body portion and a king-bolt, a socket surrounding the king-bolt and extending within the body portion, a reach-bracket extending Within the socket and surrounding the king-bolt, and means for preventing disengagement of the parts.

5. In an axle having a main metallic body portion and a king-bolt formed integral therewith, of a socket surrounding the king-bolt, a reach-bracket extending within the socket, and means for preventing disengagement of the parts.

6. In combination in an axle, a socket, a king-bolt formed integral With the axle and extending from the socket, a reach-bracket forming a bearing cooperating with the socket and king-bolt, and means for preventing dis engagement of the parts.

'7. In combination with an axle provided with a king-bolt, a conical socket surrounding said king-bolt, a reach-bracket projecting Within said socket and forming a pivot for the axle, and means for preventing disengagement of the parts.
