CAR-WHEEL.
i Specification of Letters Patent.
' Patented Sept. 29, 1908.-
Application filed October 11, 1907. Serial No. 396,878.
To all lwhom it may concern:
Be it known that I, OswALD S. PULLIAM, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Car-Wheels, of which the following is a specification.
My invention relates to car-wheels and more articularly to steel-tired wheels.
In t e accompanying drawing, which illustrates applications of my invention, Fi ure 1 is a cross sectional view of a car-whee flask and steel-tired wheel located therein; Fig. 2 a similar view of my wheel showin position of wheel-center; Fig. 3 a sectiona view of iinished wheel taken on line 3 3 of Fig. 4;
Fig. 4 a broken plan 3' and Fig. 5, a broken plan of a modified form of wheel-center.
Referrin to the drawing, 1 designates a steel-tire ofthe usual and well known form inclosing a wheel-center. The wheel-center as illustrated and as preferred is made of cast-metal and comprises a hub-portion 2 and a plurality or series ofradially extending members or pieces 3. These members 3 may be in the form shown by Fig. 3 or in the form of spokes as shown by Fig. 5. The members 3 are formed integral with the hub 2 and are each formed on its outer end with a head 4. In addition to the head 4 each member is formed with one. or more vwaved or corrugated portions 5 the number, shape and de th of the corrugations may be varied.
n the drawing, I have illustrated the preferred method of making my car-wheels.
That is to say, Fig.4 1 shows a flask 6 of the usual style employed in making car-wheels with the steel-tire embedded in the molding sand. The mold-cavity for the wheel-center is formed within the steel-tire, or if desired instead of employing a steel-tire for a chill another form of chill may be used. The mold-cavity in addition to being formed to roduce the hub and the radial members, is formed to produce the waved or corrugated portions in said radial members of the wheelcenter. The metal to'form the wheel-center is poured into the mold-cavity against the steel-tire or other form of chill and assumes the position shown by Fig. 1. After pouring, though, the wheel-center contracts somewhat, causing the periphery of the wheelcenter to draw away aslight distance from the steel-tire into the position as illustrated pressure to force the center against the tire as shown by Fig. 3. The pressure tends .to straighten the corrugated portions, said corrugations being of less depth after being pressed than before the pressure was applied.
In the form of Fig. 5, the corrugated portions of the s okes, after contraction as abo-ve describe are bent or straightened by means of suitable tools. The inner surface of the tire is preferably provided with a series of nibs 7 against which the wheel-center is poured.
What I claim is:
1. A steel-tired car-wheel having a castmetal wheel-center comprising a hub-portion and' a plurality of radially extending segmental members formed integral with the hub-portion, each of said members formed with a waved or corrugated portion and a tire-contracting-member.
2. A car-wheel having a metallic tire, and a separate wheel-center comprising a hubportion andy a plurality of radially extending segmental members formed integral with the hub-portion, each of said members formed rwith a waved or corrugated portion.
3. A car-wheel having a metallic tire, and a separate wheel-center comprising a hubportion and a plurality of radially extending segmental members formed integral with the hub portion, each of said members formed with a waved or corrugated portion and a tire-contacting-member. Y
4. The method of making car-wheels which consists in casting a wheel-center with waved or corrugated radially extending members within a steel-tire, and then after the contraction of the wheel-centersubjecting the corrugated portions to sufficient pressure to cause the periphery of the wheel-center to come into contact with the tire.
5. The method of making car-wheels which consists in casting a wheel-center with 100 waved or corrugated radially extending In testimony whereof I aHx my signature members Within a chill, placing the Wheeiin presence of' two Witnesses. center Within a metallic-tire and then subj eating the corrugated portions of the Wheel- OSWALD S' PULLIAM' 5 center to suiieent pressure to cause the pe- Witnesses:
