Definitions

• My invention relates to improvements in fluid pressure pumps or motors for air and other fluids for diiferent purposes of the character disclosed in my copending application serial No. 230,862, filed November 3, 1927, of which this is a division, and consists in improved means for constantly lubricating the actuating parts of such a pump, as will hereinafter more fully appear.
• Figure 1 is a vertical sectional view of a pump equipped with my improved lubricating system
• Fig. 2 is a detail, as seen when looking in the direc tion of the arrows 2-'2 in Fig. 1.
• the numeral 5 indicates the crank-case, in which a balance-wheel 6 is mounted, and to which wheel and the piston 7 a connecting rod, as 8 is eccentrically secured, the balance-wheel being actuated by the shaft 9 to reciprocate the piston 7 (having a valve 7 thereon) in the cylinder, as 10, but
• I provide an oil reservoir 12 to which the crank-case 5 is secured, as by screw bolts 13, into which reservoir oil is supplied through an inlet 14.
• a passage 15 is provided through a wall of the reservoir and extends upwardly therein, and to which passage a pipe 16 is connected, the vertical portion of the passage having a suitable valve therein for controlling the oil flow, and in practice I ha c-e found that a spring-controlled valve as 17 is satisfactory.
• the pipe 16 extends to the upper end of cylinder 10 and is connected to its intake by a coupling 18 having an orifice 19 therethrough which preferably leads to a glass tube 20 in which the lubricant may be inspected, the tube in turn communicating with an orifice 21 in the cylinder intake 10',
• a needlevalve 24 is provided, the head 25 of which may comprise a dial or indicator, Fig. 2, so that the valve may be set in a predetermined position by bringing a character on the dial in registry with a pointer 26 secured to the coupling 18 or otherwise.
• the reciprocating action of the pistons and rotary action of the balance-wheel constantly draw oil from the reservoir 12 up through the pipe 16 and the orifice communicating therewith, and by means of the needle-valve 24 such lubricant is caused to pass into the intake 10 in atomized condition, so that during the operation of the apparatus the lubricant is continuously spraying into the intake and thence finds its way through valves 7 and 7 into the spaces between the casing 5 and wheel 6, and also into the piston-rod connections and into cylinder 10 to lubricate all of theinterior parts, while any undue surplus carried between the lower side of said wheel and casing is forced through the opening 30 in the upper side of the reservoir 12, which open 4 ing is normally closed by a spring-controlled valve 31 until the pressure of the oil displaces it, when the oil flows into the reservoir to be reused, the valve becoming automatically closed whenever such pressure is relieved.
• an oil reservoir in combination, an oil reservoir, a crank-case associated with the reservoir, a shaft extending into the crank-case, a wheel on the shaft, a connecting-rod mounted on the wheel, a piston connected to the rod, a cylinder in which the rod and piston reciprocate, means exteriorly of the crank-case connected 00 to the reservoir and with the e linder for conveying oil therefrom and ischarging the same into the cylinder during the reciprocation of the piston,,and' means for returning surplus oil from the crank-ease into the reservoir.
• an oil. reservoir a. crank-case associated with the reservoir, 8.- m shaft extending into the crank-case, a wheel on the shaft, a connecting-rod mounted on the wheel, a piston connected to the rod. and having a valve associated therewith, a cylinder in which the rod and piston reciprocate said cylinder having a valve associated therewith,
• means for enclosing the wheel and parts associatedtherewith in the crankcase means for conveying oil from the reservoir into the cylinder, and means for atomizing the oil as it discharges into the cylinder.
• an oil reservoir in combination, an oil reservoir, a crank-case associated with the reservoir, a shaft extending into the crankcase, a balance-wheel on the shaft, a connecting-rod mounted on the wheel, a piston connected to the rod, a cylinder in which the rod and piston reciprocate, a pipe connected at one end to the reservoir, a coupling connecting the opposite end of the pipe to the cylinder, and means for actuating the-piston to propel oil from the reservoir to the cylinder to lubricate the latter and parts associated therewith.
