Specification of Letters Patent.

Patented June 4, 1907.

Application filed January 16, 1907. Serial No- 352,663.

in F ifth-WVheels, of which the following is a specification.

This invention relates to improvements in fifth wheels.

The main object of this invention is to provide an improved roller bearing short turn use in connection with elliptical springs for the support of a vehicle body.

Further objects, and objects relating to structural details will definitely appear from the detailed description to follow.

l/Ve accomplish the objects of our invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying -the features of our invention is clearly illustrated in the accompanying drawing, forming a part of .this specification, in which:

Figure 1 is a detail plan of our improved fifth wheel. Fig. 2 is a detail transverse section taken on a line corresponding to line 22 of Fig. 1 through the bearing segments showing the form and arrangement thereof and of the arrangement of the rollers. Fig. 3 is a detail front elevation of our improved fifth wheel, a portion of the upper bearing segment 4 being broken away to show structural details. Fig. 4 is a longitudinal central section thereof taken on a line corresponding to line 4-4 of Fig. 3. Fig. 5 is a detail section taken on a line corresponding to line 55 of Fig. 4. Fig. 6 is an inverted detail of the upper bearing segments 4. Fig. 7 is a detail plan view of the lower bearing segment 5.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of section lines, and similar reference characters refer to similar parts throughout the several views.

Referring to the drawing, 1 represents the cape.

axle of a vehicle, 2 the head block, and 3 an elliptical spring.

The upper member of our improved fifth wheel consists of the bearing segment 4, which is channel-shapedin cross sectlon opening downwardly. A cross-piece 12 is pro-- vided, forming a seat for the head block 2. The cross-piece is provided with laterally projecting perforated ears 14. The clips 13 by means of which the head block 2 and spring 3 are secured are arranged through these perforated ears 14. To further aid in securing the head block upturned flange-like lips 2-3 are provided for the cross-piece. Projecting rearwardly from this cross-piece 12 are diverging arms 15 upon which the forward ends of the reaches 6 are secured. On the inner sides of these arms at their forward ends are upturned flange-like lips 16 which assist in retaining the reaches thereon. At the rear ends of the arms 15 is a cross-piece 17 having a king bolt bearing thereon. Extending from the rear ends of the upper bearing segment to the arms 15 arebrace arms 18. This makes a very strong and at the same time light construction and enables the easy securing of the parts rigidly thereto.

The lower bearing segment 5 is adapted when the parts are assembled to project into the upper bearing segment as clearly appears in Fig. 3. The lower bearing segment is provided with a cross-piece 19 adapted to rest on the top of the axle to which it is secured by suitable clips 20. The arms 21 project rearwardly from the bearing segment and are provided at their rear ends with a king bolt bearing. To further support the king bolt 8 and to brace the parts braces 7 extending from the axle to the king bolt are provided, the rear ends of the braces being provided with a suitable king bolt bearing. The clips 20 secure the braces 7 to the axle.

A pair of bearing rollers 10 provided with suitable journals are arranged in the upper bearing segment, being preferably located slightly in advance of the head block. These bearing rollers travel upon the lower bearing segment 5, which is provided with a flat face, the bearing portion thereof having a slot 11 therein. See Fig. 7. This allows any dirt which may get into the bearings to es- However, owing to the shape and arrangement of the bearing members, the bearing portions are very effectively protected from the dirt.

To effectively secure the parts of the bearing segments together the segment 4 is provided with a central downwardly projecting lug or boss 22, which projects through the slot 11 in the lower bearing segment. A bolt 9 is arranged through this lug or boss, on the lower end of which is a nut which serves to retain the parts at this point. See Figs. 4, 5 and 6.

By arranging the parts as we have illustrated and described we secure a very rigid and strong construction, although the same may be made of comparatively light mate rial. The bearing portions also very readily free themselves from dirt. The structure is especially adapted and designed by us for use with the double elastic springs, although it may be adapted for use in connection with other springs.

We have illustrated and described our improved fifth wheel in detail in the form preferred by us on account of structural simplicity and economy and the strength and rigidity of the parts when so arranged. We are,

.however, aware that it is capable of considerable variation in structural details without departing from our invention.

Having thus described our invention, what we claim as new and desire to secure by Let ters Patent, is:
