FIFTH-WHEEL CONSTRUCTION.

Application filed November 21, 1906.

Be it known that 1, JOHN REPETTO, a cit-izen of the United States, and a resident of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in F ifth-lV heel Constructions, of which the following is a full, clear, and complete disclosure.

My invention relates to vehicles and particularly to that class of the same having fifth wheel constructions.

The main objects of my invention are to provide a light, strong and durable fifth wheel construction, made principally of metallic strips and angle irons; to provide an improved mounting for a traction pole; to provide improved mountings for the springs of a vehicle; and to provide other improvements as will appear hereinafter.

In the accompanying drawings, Figure 1 is a fragmentary side elevation of a vehicle constructed in accordance with this invention; Fig. 2 a longitudinally vertical central section of Fig. 1; Fig. 3 a fragmentary top plan view taken on line 3-3 of Fig. 1; Fig. 4 an enlarged perspective fragmentary view of a modified form of a portion of the ve hicle; Figs. 5, 6, and 7 are enlarged per spective views of details of the vehicle; and Figs. 8 and 9 are fragmentary longitudinal vertical sections of modified forms of portions of the vehicle.

The body portion of the vehicle is carried on the longitudinal angle beams 11. To the under side of the forward end of the same are the transverse angle bars 2, bolted to which are similar angle bars 3. Between the angle bars 2 and 3 are placed posts 4 of a length equal to the space between said bars, and through said posts are passed bolts securing the same together. Secured to the under side of the angle bar 3 is a strip 5, bent to present horizontal webs in two planes. Wherever two angle bars are bolted together by one web of each and it is desired to stiffen the channel bar so formed, I use these posts 4 through which and the webs passes the bolt 4, the construction being shown very plainly in Fig. 6. The posts 4. by means of bolts 4: and the strip 5 are riveted to the ring 6, on the under side of and concentric with which is the ring 7, bolted to the under side of which are the angle bars 8 and to the latter are bolted simi- Specification of Letters Patent.

lar angle bars 9. Bolted to the under side of the strip 5, is a stiffening bar 10 and to the under side of the latter is a small rectangular plate 41.

The angle bars 9 extend transversely across the under side of the annular ring 7 and are supported upon and bolted to the angle bars 1111 which diverge forwardly. To the under side and at the rear of the angle bars 11-11 is bolted the angle plate 12, bolted to which are similar angle plates 13. To the intermediate portions of said angle bars 11-11 is bolted the angle bar lzl: to which latter is bolted a similar angle bar 15. Each of the angle bars 11-11 is bolted to a similar angle bar 16 and to the under sides of these latter are bolted the trusses 1717 respectively, each of which supports a post 18 on its intermediate portion, which post bears on the under side of its respective angle plate 15. Further trusses 19-19 connect the trusses 1717 respectively with the under side of the angle bars 15.

The forward end of each angle bar 16 has its vertical portion turned at right angles to form a tongue 20. Bolted to the forward end of the vertical web of each angle bar 11 is the angle plate 21, which is turned outwardly to form a tongue 22, which tongue is in the same plane as the tongue 20. The forward ends respectively of each of the angle bars 11 and 16 are sheared off so as to be in the same plane with the outer surfaces of the tongues 20 and 22.

Referring to Figs. 5 and 6, reinforcing pieces 23 are bolted to the tongues 20 and 22, the said reinforcing pieces having their outer ends flush with the tongues 22 and their inner ends flush with the edges of the horizontal webs of the angle bars 11 and 16 respectively. These reinforcing pieces are turned inwardly under the tongues 22 respectively forming tongues 24.

Bolted to the front surfaces of the tongues 20 and 22 is the front angle bar 25 of the vehicle, having its horizontal web overlapping the forward ends respectively of the hori- Zontal webs of the angle bars 11.

Upon each extremity of the horizontal web of the front angle bar 25, is fastened the corrugated step 26 and bolted to the under side of said web is the hanging step 27. Between the flattened upper portion of the step 27 and the tongue 24 is a strengthening post 28. To the rear of the intermediate portion of the front angle bar 25 is bolted the angle bar 29, having its extre1nities terminating and abutting against the reinforcing pieces 23 and the edge of the horizontal web of the angle bar 16, as shown in the modification shown in Fig. 6.

In Fig. 4, of the junction between the forward extremities of the angle bars 11 and 16 respectively and the front angle bar or draw bar 25 of the vehicle, the reinforcing pieces 23, together with the rearwardly bent tongues 24 are omitted and the tongues 20 and 22 respectively are bolted directly to the vertical web of the angle bar 25. A tongue 24 is turned rearwardly from the bottom of the tongue 22, thus making the junction complete but omitting the hereinbefore mentioned reinforcing pieces. Otherwise the construction is the same as that disclosed in Figs. 5 and 6, the plate 21 corresponding to the plate 21 and the post 28 corresponding to the post 28.

On the middle portion of the top web of the front angle bar 25, is the apertured metallic plate 30, on the top of which is bolted a double t'ree 31 by means of the bolt and nut 32. To the extremities of the double tree 31 maybe fastened the usual whifii'e trees. To the front of the angle bar 25, is attached a pair of lugs 25 which may be utilized as an attaching means for shafts.

A transverse end spring 33 is attached centrally to the under side of the angle bar 13 and has its ends suitably connected respectively to the rear ends of a pair of side springs 34, which in turn have their forward ends journaled in lugs 35 bolted to the tongues or flanges 24 respectively. The intermediate portions of the side springs are attached to ournal boxes on the front axle by any well known means.

Between the angle bars 11-l1 and terminating in a position under the center of the annular plates 6 and 7 is the pole 36. The inner end of this pole is embraced by the angle bars 39 and 39 respectively, the vertical webs of the bars overlapping the top surface of the pole, under which latter and secured to these angle bars is the strap 37. The inner extremity of the pole is thus securely embraced and is wedge-shaped to conform to the diverging of the angle bars 8939. The rear end of the pole fits in between thehorizontal webs of the angle bars 14 and 15. It will be seen that the parts above the annular plate 6 are all rigid with one another, but not connected with the annular plate 7, which latter is rigidly connected with all the parts located below the same, the entire set of parts being supported by the springs on the axle of the vehicle. The two parts, however, are connected by a king-bolt 40 passing through the angle plates 3 and 5 and the annular plates 6 and 7 may be revolved relatively to one another in the usual manner of a fifth wheel construction.

In the modification illustrated in Fig. 8 of the mounting of the double tree a bolt 32 extends entirely through the webs of the angle bars 11, 16 and 29, and also through the pole 36, being secured in place by a nut upon its lower end.

In the modification illustrated in Fig. 9,

the strip has secured to the end thereof a bar 1.0, shorter than the stiffening bar 10 shown in Fig. 2, and around the king-bolt 40 it is provided with a downwardly extending cylindrical cup 10", around the outside of which is fitted a larger but similar cylin-' drical cup 8', secured to the plate or bar 8, which in turn is fastened to the top of the angle bar 8 and extends lengthwise of the same. By this construction, the king-bolt 40 is relieved from all shearing strains, the function of the king-bolt being merely to prevent the separation of the said cups.

In certain locations any shaped structural channel bars may be substituted for the' single or double angle bars, and either web of the latter may be utilized to effect the same result. Throughout the construction of my apparatus, wherever two angle bars are bolted together so that they present two parallel webs having a space between them, metal posts 4, may be interposed between the webs; eachof these posts has a passage, through which may pass a bolt, and thus serve to resist the compression of an inward bending of the webs when the bolts are tightened, as in a draw-bolt construction, as illustrated in the case of the king-bolt 40 in Fig. 2, or when any other force is applied to the outside of the webs. When converging bars are made up of two angle bars, as shown 'in Fig. 6, the said posts 4 add greatly to the strength and stiffness of the bars. The bolts passing through these posts and those used throughout the vehicle may be of any suitable construction, and may have angular or round shoulders, and their heads may be countersunk. lVherever desirable the extremities of the bolts may be screw-threaded to receive nuts, or may be struck or swaged into a rivet like head.

While I have described specifically certain modifications of my invention, I do not wish to be construed as limiting myself to the details illustrated, since it is apparent that many changes and modifications which might arise, or be necessitated by the application of my improved fifth wheel to different kinds and styles of vehicles, are fully within the aim and scope of my invention.
