OUR ADJUSTABLE HANGERS avoid all liability of binding; the bearing or
boxing-part is free to find its natural bearing; the ball and socket
self-oiling pillow-block (Fig. 1, and Post Hanger Fig. 2. See
engravings) have the same advantages. All have the improved self-oiling
attachment making it necessary to oil but once in three months, and
cleaning twice a year.
These bearings are adjustable every way as much as required, and not at
all liable to heat.

Rules to Find the Speed of Pulleys and Gearing.
PROBLEM I.
The diameter of the driven pulley or wheel being given, to find its
number of revolutions.
_Rule_--Multiply the diameter of the driver by its number of
revolutions, and divide the product by the diameter of the driven: the
quotient will be the number of revolutions of the driven.
PROBLEM II.
The diameter and revolutions of the driver being given, to find the
diameter of the driven:
_Rule_--Multiply the diameter of the driver by its number of
revolutions, and divide the product by the number of revolutions of the
driven: the quotient will be its diameter.
PROBLEM III.
To ascertain the size of the driver:
_Rule_--Multiply the diameter of the driven by the number of revolutions
you wish to make, and divide the product by the revolutions of the
driver: the quotient will be the size of the driver.
_Note_--FOR GEARING take the diameters at the PITCH LINE, or take the
NUMBER OF COGS instead of DIAMETERS and use the same rules.
