JOHN T. TOWSLEY, OF CINCINNATI, OHIO.
WHEEL FOR TRUCKS.
SPECIFICATION formingpart of Letters Patent No. 746,900, dated December 15, 1903.
Application met septemter, 1902. serai No. 122.2792. et, man.;
To all whom, may concern:
Be' it known that I, JOHN T. TOWSLEY, a citizen of the United States OEiAmerica, and a resident of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Wheels for Trucks,V
of which the following is a specification.
My invention relates to the j ou rnal-forks of wheels for trucks. Il have found that these forks in use break at the point wherethe shank of the fork contacts the lower end of the bracket which is secured to the 'truckbody. I have found, likewise, that a solid wrought-metal shank breaks more quickly than a hollow metal shaukwhich has been interiorly annealed, but still these hollow annealed shanks likewise break at the point aforementioned.
The object ofpmy invention isto provide a fork for truck-whee'lswhich .will be strong at the point upon which vthe greatest strain is brought and in which the strain is more evenly distributed. This object I attain by the means described in the speciiication and illustrated in the accompanying drawings, in which- Figure lis a view showing one end of theY truck-body, with the bracket shown in longitudinal section and the fork embodying my invention shown in elevation. Fig. 2 is a longitudinal sectional detail'view of the shank larged scale. Fig. 3 is a transverse vertical sectional view of the same. Fig. 4 is a horizontal sectional view of the same, taken upon line z Z of Fig. 2. l
Referring to the parts, brackets A are attached to the front and rearends of the truckbodycil in the usual manner. Infthe top and bottom of each bracketA are vertically-alined holes a and a2, the top one, a', being of smaller diameter than the lower and its under side being beveled. Shankbof journal-fork B has at its upper end a reduced portion and at the lower end of the reduced portion a beveled portion B. At the lower end of the shank is an enlarged collar B?. BracketA rests upon shank b, with the beveled portion B contacting the bevelededge of hole A and the lower 5o end of the bracket standing free above collar B2. The weight of the truck being thus borne by the upperpend of the shank, some strain is taken off of the portion of it coming near the lower end of bracket A."
When the truck -is `being moved, either pushed or drawn, the wheels occupy a position parallel to the direction in which the truck is moved, the swveled joint allowing the wheel to occupy this position. The strain, therefore, upon the shank occurs along its vertical longitudinal diameterthat is, the diameter which lies midway between the forks.
- The shank embodying myinvention is made hollow of cast metal, has two vertical ribs b2 b3 formed upon the interior of the shank at diametrically oppositeA points .and upon the aforesaid vertical longitudinal diameter.' of the shank. The ribs extend from a point in the shank below the lower edge of bracketA up into the interior of the shank well above said point. The interior of shank l) and the ribs b? bs are annealed. By thusplacing ribs upon the interior of the shank at its longitudinal vertical axis Iv not only secure a greater thickness of metal at that point, but I likewise -secure a much Alarger annealing-surface,
so that I iind Shanks made in this manner will stand a much greater strain than Shanks as heretofore made.
What I claim isl. A journal-fork for trucks whose shank consists of a hollow metal casting having upon its interior a vertical rib upon its vertical longitudinal diameter and being interiorly annealed substantially as shown and described.
-2. A journal-fork for trucks whose shank consists of a metal tube having upon its longitudinal diameter two internal ribs at diametrically opposite points and being interiorly annealed substantially as shown and described. p
3. In combination with a' truck a bracket having an upper and alower vertically-alined hole the upper one being smaller in diameter than the lower, a journal-*fork whose upper end has a shoulder upon which the edges of the upper hole of the bracket bear to sup- 4 IOO duced in diameter, in combination Witha bracket rests to support the Weight of the journal-fork having a hollow metal shank truck substantially as shown and described. with ribs u on its interior u on its vertical longitudinali diameter, the ipnterior of the JOHN T' TOWSLEY' shank being annealed, and near the upper Witnesses:
edge of bhe shank an external collar upon W. F. MURRAY,
which the edges of the upper hole in the A. MCCORMACK.
