NEN GH ARM DAVIS PAMILY SEWING CHINE

Before the machine leaves our hands it has been minutely inspec.ed, and
every mechanical defect corrected; it has been tested with various sizes of
thread, ranging from No. 4o linen to No. 159 cotton, and fonnd to work satis-
factorily in every respect.

When unpacked the machine should be found in complete ranning order,
threaded ready for sewing, and with a sample of work under the presser foot,
as it came from the hands of the inspector.

Parties who have never used “The Davis" before, should first observe how
the machine is threaded; but if, from any cause, it should become unthreaded
in transportation, the operator should follow the directions for threading,
given hereafter.

OILING THE MACHINE.

‘This is the most important rule to be observed, for care in oiling the
bearings insures durability and ease of motion, and prevents premature wear.

To oil the parts inside of the head, raise the needle bar to its highest
point, and put one drop on each side of the needle and feed bars, one drop in
each of the two holes in the top of the cam house, and the same quantity in
the holes at each end of the arm; swing aside the arm plate (the plate at the
back of the arm) and oil the bearings of the eccentric lever on the center
screws, put one drop in the hole in the center of the bed plate, one on the
journal of the balance wheel, and one on each of the bearings of the pitman
and treadle. E

To insure a free movement of the loose pulley (Hand Wheel) when wind-
ing bobbins, a little oil should occasionally be put in the holes H and I.

‘The places which should be oiled, as above described, are indicated by the
letters A, B,C, D, E, F, G, H, 1, J, K, 1, M, O, P, Qand R, in Fig. 1,

Occasionally a little oil should be applied to the connection between the

“eccentric lever and the shuttle lever, to do this the head may be tipped back
on the table.

Run the machine several revolutions swiftly to distribute the oil on the
hearings; then wipe off all excess of oil, that it may not soil the work or
clothing, Ifthe machine runs hard because of the use of poor oil, or if it
becomes gummy by long standing, use a little kerosene (which will soon re-
move the gum) after which apply good fresh oil.
