PATENT JAMES J. FETZER, OF COLUMBIANA, ASSIGNOR TO THE HERBRAND COMPANY, OF FREMONT, OHIO.
FIFTH-WHEEL.
SPECIFICATION forming part of Letters Patent No. 459,360,- dated September 8, 1891.
Application filed January 26, 1891. Serial No. 379,197. (No model.)
To aZZ whom it may concern:
Be it known that 1, JAMES J. FETZER, of Columbiana, in the county of Golnmbiana and State of Ohio, have invented a new and useful Improvement in Fifth-Wheels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure lis a perspective View of my improved fifth-wheel. Fig. 2 is a vertical sec tion on the line II II of Fig. 1. Fig. 3 is a vertical section on the line III III of Fig. 2, and Fig. 4 is a vertical section on the line IV IV of Fig. 1.
Like symbols of reference indicate like parts in each.
My invention relates to an improvement on the fifth-wheels described in the following patents of Jacob Herbrand: N o. 244,599, dated July 19, 1881, and No. 277,725, dated May 15., 1883.
In the drawings, 2 represents the top plate of the fifth-wheel, having bearing-lugs 3, forming a segmental upper circle-plate, and 4; is the bottom plate, on the under side of which the axle 5 is set and is held fast by clip-yokes 6. The bottom plate has bearing-lugs 7 ,which correspond to and fit against the lugs 3 on the top plate and is provided with a boss 8, extending downwardly back of the axle and resting on a seat in the lower reach-iron 9, which extends forwardly from said seat and is connected with a lug 10 on the top plate by an upwardly-extending arm or bolt 11,which may be made in the same piece with the reachiron. The top plate has a socket 12, which fits around a vertically-projecting stud 13 on the boss 8 and back of and below said socket is formed with a shoulder let,which has a bearing against the rear top portion of said boss, thus bracing the top plate and preventing it from tipping on the stud 13. Back of the shoulder 14 a reach iron 15 extends rearwardly and in substantially the same plane with the top plate above the correspondinglyshaped lower reach-iron. The king-bolt 16 extends vertically through the stud 13, the boss 8, and the lower reach-iron, as shown in Fig. 2.
The fifth-wheel so constructed possesses ad- I vantages as respects strength, compactness of structure, and cheapness. By having the reach-iron 15 in substantially the same plane with the top plate and integral therewith I am enabled to dispensewith the usual axlebed. WVhen the axle-bed is desired to be used, the lower reach-iron should be curved downwardly under the axle, (more than shown in Fig. 2,) so as to make room for the axle-bed. By extending the bottom plate in the form of the boss 8 down to and giving it a firm seat and lateral bearing on the lower reach-iron I am also enabled to support the lower reachiron perfectly without an axle-plate,which is substitutedinfunction by said boss 8. Ithus reduce the number of parts to a minimum and obtain a cheap, strong construction.
It is obvious that the wear of parts occurs almost exclusively between the top and bottom plates at the intersection of stud 13 with socket l2 and upon bearing-lugs 3 and 7 of top and bottom plates, respectively. To take up this wear I provide for thorough adjustment of said plates with relation to each other. Owing to the conical form of vertically-projecting stud 13 on the bottom plate, it readily accommodates itself to wear in the walls of socket 12 in top plate, adjustment-space 17 being left above for this purpose, while for the same reason adj ustment-space 18 is pro vided between the top and bottom plates 2 4, immediately overthe axle and between the two sets of bearing-lugs 3 and 7, as shown in Fig. 3. WVear having occurred between these parts, they are drawn snugly together by king-bolt 13 and bolt 11, thus preventing noise or rattle, and, being retained in their proper relative position by two bolts, the parts are prevented from wearing unevenly. It will be observed, further, that boss 8, together with its stud 13, presents a most excellent bearing for the top plate 2 and lower reach-iron 9, both of which turn upon it and find thereon lateral as well as end bearings, the top plate having its end bearing on the beveled sides of stud 13 and its lateral bearing upon the rear top portion of boss 8, which engages shoulder 14 in the top plate, while reach-iron 9 has a firm end bearing upon the lower extremity of said boss 8 and a lateral bearing against the rear side thereof, the latter being snugly seated in the curved recess 19, formed in ani gle 20 of the reach-iron, from which point said a lateral bearing on said boss, a lower reachiron haying a lateral bearing against the rear of the boss and a bearing on the bottom there- 15 of, and a king-bolt passing through the top plate, boss, and lower reach-iron.
In testimony whereof I have hereunto set my hand this 16th day of January, A. D.
