UNITED STATES PATENT OFFICE.
A. F. AHRENS, OF PHILADELPHIA, PENNSYLVANIA.
BALL-CASHIER.
Specification of Letters Patent No. 5,102, dated May 8, 1847.
To all whom, it may concern:
Be it known that I, ADoLPH F. AHRENs,
of the city and county of Philadelphia and Figure 1 is the caster in plan; Fig. 2, the
case in perspective; Fig. 3, projection of case of the caster and cover detached, and Fig. 4, a view of the ball.
The same letters indicate like parts in all the figures.
There have been casters made heretofore with balls and sockets, but in those there was nothing to keep the ball from the socket, or rollers were interposed; in these the rollers are diflicult to manufacture and adjust in proper position so as to have them all bear properly on the ball their expense is great and they are found in practice to work with great friction. A great difiiculty has arisen from their striking for when rollers are used a portion of them only can act at a time and the others will scrape over the surface of the ball as it turns, especially when there is a great weight brought onto them; but by my improvements I obviate act even under great pressure.
these objections, and construct a cheap, useful and efficacious caster that will always The construction is as follows: A semia flanch projecting'outward around its edge onto which a flat cover (2)) is screwed with a hole in the center sufliciently large for the caster ball (0) to project through in the curved part of the case there are three or more holes bored. at an angle of about45 which point radially intoward the center; into these holescase hardened screws (d) spherical socket or case (a) is made with 1 are inserted which project a little into the interior and on them a perfectly spherical ball (0) rests and turns. When this ball is put into place the cap ((2) is screwed down and secures the ball and the caster is complete, and will not under ordinary circumstances strike or be liable to get out of order the points being readily'and easily adjustable.
