Description
UNITED STATES PATENT OFFICE.
FREDERIC DORSEY DELLINGER AND SAMUEL H. HUNT, OF WAYNESBOROUGH,
VIRGINIA.
IMPROVEMENT |N CAR-TRUCKS.
Specication forming part of Letters Patent No. 118,518, dated August 29, 1871; antedated August 17, 1871.
To all whom it. may concern:
Be it known that we, FREDERIC DoRsEY DEL- LINGEE and SAMUEL H. HUNT, of Waynesborough, in the county of Augusta and State of Virginia, have invented new and valuable Improvements in Car-Trucks; and We do hereby declare that the following is a full, clear, and exact description ofthe con struction and operation of the saine, reference being' had to the annexed drawing making a part of this specification, and to the letters and gures of reference marked thereon. Figure l of the drawing is our truck in plan view. Fig. 2 is a vertical section through one wheel and journal-box. Eig. 3 is a side view of the same, the side ofthe housingfor the journalbox being removed; and Fig. 4. is a longitudinal vertical section through one ofthe journal-boxes.
The nature of my 4invention consists in the construction and novel arran gem ent of devices whereby intercalated bearing-rollers are adapted for use in car-trucks to serve as bearings for the journals ofthe car-axles.
In order to enable others skilled in the art to which our invention appertains to make and use the saine, we will now proceed to describe its construction and operation.
A represents the frame of the truck. B B are the axles, and C C the wheels placed on the axles. D D represents boxes or housing inclosing the friction-wheels E E and the ends of the axles. The axle immediately inside of each wheel is surrounded by a collar, (t, supported by arms G G from the frame A, and said arms are further braced'by braces H H. In each ofthe boxes D, between the axle and the frame ofthe truck, are
placed two of the rollers or Wheels E. These wheels are made about twice the diameter of the axle, and provided with circular ianges b b a suitable distance apart. These anges on the tWo wheels lnesh into each other and' form the upper bearing for the axle. The journals of the wheels E E are placed in upper boxes d and lower boxes or packing-boxes j', which are fastened together by a central screw-bolt, e, as shown in Fig.' 4. These journal-boxes d j' are at their ends inclosed by stress-blocks h to resist the diagonal pressure ofthe rollers. The axle bearing, as above inentioned, against the rollers E E, on its upper side, has a packing-box, I, underneath, resting on the seat-plate, J, which forms the bottom of the housing D. The Whole housing D is held together by stirrups z' i, as shown in Fig. 2.
Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
. In a car-truck, the combination with the grooved axle B of the intercalated bearingrollers E, journal-boxes df, stress-blocks h h, packing-box I, housing D, and the braced adjustable arm G with its terminal collar a, substantially vas herein shown and described.
In testimony that we claim the above We have hereunto subscribed our names in the presence of two witnesses.
FREDERIC DORSEY DELLINGER. SAMUEL H. HUNT.
