    Patent number: 3933107
    Abstract: A sewing machine is provided with a lubricating pump that is operated when work feed members of the machine are engaged or released whereby a quantity of lubricating fluid is delivered to the machine mechanism immediately before the mechanism begins to run. A reciprocatory pump is used and supplies the fluid to a manifold having multiple feed apertures over required lubrication locations for the fluid issuing from the apertures to fall onto said locations. The manifold is displaceable as a unit to give access to the mechanism below it.
