Mr. Espy Gallipher, of Schellsburg, Pa., has devised an axle journal
having a groove lengthwise upon its upper side which extends back upon
the surface of the axle and communicates with an oil cup. A sliding
rod occupies a portion of the groove; when this rod is drawn out it
permits the oil to fill the groove; when it is pushed into the groove
in the axle, the oil is ejected and a further supply is cut off.
An improved pill machine, invented by Messrs. W. N. Fort and R. R.
Moore, of Lewisville, Ark., is adapted to the manufacture of pills in
large quantities. The machine has mechanism for grinding and mixing
ingredients, a grooved wheel and trough for forming the pills, and a
device for applying powder.
An improvement in millstone adjustments has been patented by Mr.
Stephen P. Walling, of South Edmeston, N. Y. This invention consists
in a screw applied to the end of the mill spindle on which the stone
is rigidly held, so that the running stone may be forced by the screw
away from the stationary stone and held against the action of a spring
at the opposite end of the spindle, the object being to prevent the
stones from becoming dulled by contact with each other.
An improved attachment for sewing machines for soaking or waxing the
thread as it passes the needle, has been patented by Mr. Pedro F.
Fernandez, of San Juan, Porto Rico. The invention consists in a frame
secured to the arm of a sewing machine by a thumb-screw, and provided
with a clamping device for holding wax or soap.
A novel combination of a toggle and springs and levers for operating a
drag saw has been patented by Mr. Harvey Hughes, of Wheat Ridge, Ohio.
The saw, while properly guided, is free to move up or down without
affecting the leverage.
An improvement in filters, which consists in re-enforcing the felt
disk with a backing of wire cloth to enable it to resist heavy water
pressure, has been patented by Mr. B. P. Chatfield, of Aiken, S. C.
A basket having light sheet metal sides attached to a wooden bottom by
crimping the edges over a rib on the periphery of the bottom, has been
patented by Mr. Samuel Friend, of Decatur, Ill. The handle and lid may
be easily removed to permit of packing and storage.
An improved cross bar for fastening doors, patented by Mr. Richard
Condon, of La Salle, Ill., has a spring acted portion which engages a
socket on the door casing, and is retained in that position by a
spring catch.
