Fig. 2029 illustrate the Myers Self-Lubricating Pump 
Jack, engine driven, a novel device in which all gears and 
moving parts are enclosed in a one-piece casting, forming 
the Oil Reservoir. This construction not only insures per¬ 
fect and continuous lubrication, but protects the moving 
parts from dust and dirt, greatly increasing the life of 
the Jack. Furthermore, it guarantees perfect safety. 
CONSTRUCTION—Gear and Pinion are machine cut and 
move in oil. The Gear is fitted with an eccentric cast 
integral which operates a walking beam hinged at one end 
to the main frame or base. The revolving of eccentric 
moves the forward end of walking beam vertically giving 
a 6-inch stroke to the pump piston. Can be used in con¬ 
nection with any make of Pump Stand. Has Angle Steel 
Arms, making as a whole the most durable Pump Jack on 
the market.

Fig. 1635 represent the Myers Universal Pump Jack, 
designed to be used in connection with any ordinary wind¬ 
mill head pump without disarranging the pump or pipes 
in any manner. It is mounted on a substantial circular 
base which surround the pump stand, and is bolted securely 
to the platform, and also clamped to the pump stand, 
making a most substantial job. We believe this to be a 
more practical device than the ordinary cheap jack now in 
use, which is bolted direct to the body of the pump stand 
only. 
Price $15.00 
The Myers Master Double Gear Pump Jack, as repre¬ 
sented by Fig. 2001, is the latest production, especially 
designed for use with windmill pumps for deep well work. 
It is made extra wide, measuring 13 inches between the 
gear wheels, which adapts it for use with 3-way pumps. 
It has double gears and pinions. 
The Gears and Pinions are 1% inch face, machine cut. 
The Wrist Pins are 1 inch in diameter, hard steel, ma¬ 
chine smoothed, screwed into the gear wheel, and are 
secured in addition by a lock nut. 
The Shafts are lVa inch drawn steel securely keyed to 
the gears. 
The Pulleys, 12 inches x 3 inches, are located in the 
center of the jack, providing for a center pull, thus doing 
away with all side strain as in other style jacks. 
The Frame is made in two separate pieces, held together 
with % inch steel rods. 
The Side Arms are angle steel bars, adjustable to any 
length stroke or height of pump. 
The Crosshead is extra strong, fitted with a ball and 
socket joint to attach the pump rod. This socket joint pre¬ 
vents binding and removes all unnecessary strain and fric¬ 
tion on the piston rod. The socket joint also permits the 
piston rod to pass through at any angle, or pump to set 
at any angle. 
The Myers Master Double Gear Pump Jack is designed 
to meet the demand for an extra strong jack where great 
strength and wearing qualities are desired.
