Claims.—(1.) In combination, a bicycle or tricycle, a stand
for raising the driving-wheel of such vehicle from the ground,
a friction-pinion in contact with the tire of the driving-wheel, a sharpening-disc on the same spindle or axis as the
friction-pinion, the said sharpening-disc also acting as a flywheel, and thus insuring a regular and steady motion to a
flexible shaft, by means of which the rotary motion of the
spindle is conveyed to the implement it is desired to work, as
and for the purposes specified. (2.) In combination, a
bicycle or tricycle, a stand for raising the driving-wheel of
such vehicle from the ground, a friction-pinion in contact
with the tire of the driving-wheel, a sharpening-disc on the
same axis as the friction-pinion, and a flexible or universally-jointed shaft for the purpose of developing power and conveying the same to a machine sheep-shear or other similar
implement, as and for the purposes set forth. (3.) In combination, a bicycle or tricycle driving-wheel, a friction-pinion in contact with the tire of the wheel, whereby rotary
motion is imparted to a flexible shaft, which is connected to
the axis of the friction-pinion, and a sharpening-disc or facetoool for sharpening the cutters of machine sheep-shears,
such disc being connected to the free end of the flexible
shaft, as and for the several purposes specified. (4.) The
general arrangement, construction, and combination of parts
in the attachments to bicycles or tricycles, for the purpose
of transmitting power to sheep-shears and other similar implements, as set forth.
(Specification, 11s. 6d.; drawing, 5s. 6d.)

No. 11524.—14th April, 1899.—CARL GEISSLER, of Stassfurt, Prussia, Royal Mill-manager. An improved apparatus for taking samples of pulverised and granulated
materials.

Claims—(1.) The arrangement and construction of a
machine or apparatus for obtaining average samples, containing a drum, or several drums above each other, each
with an inlet slit or opening, and rotated so that the
number of revolutions of each higher drum is a multiple
of that of the next lower drum, and hoppers, and by-pass
shoots, substantially as described, and illustrated by the
drawings. (2.) In a machine or apparatus for taking average
samples by means of rotating drums, and constructed as
described, the arrangement of an adjustable curved slide
for varying the size of the inlet-openings of said drums
substantially as described with reference to Figs. III. and
IV. of the drawings.
(Specification, 5s.; drawings, 6s.)

No. 11525.—14th April, 1899.—LETITIA MUMFORD GEMB,
of 5, West 112th Street, New York, United States of America,
Artist. Improvements in syringes for rectal purposes.

Claims.—(1.) A syringe for rectal purposes, having a reflexed handle, the main portion of which is approximately
parallel with the piston-rod, substantially as specified.
(2.) A syringe for rectal purposes, having a reflexed handle,
the main portion of which is approximately parallel with
the piston-rod, said handle being provided with a hook at
the free end thereof, substantially as specified. (3.) A
syringe for rectal purposes, having in combination a cylinder,
a piston, and an operating-rod which is bent upon itself to
form a smooth and rigid arm or handle, which, in its extreme positions, is located within reach of the fingers of the
hand which holds the cylinder, thus permitting one hand to
hold and operate the syringe, substantially as specified.

No. 11527.—14th April, 1899.—HENRY ELIAS HOWLAND,

Councillor-at-Law (assignee of Orlando Morton Thowless, of
Newark, Essex, New Jersey, United States of America, Inventor). Improvements in burners for incandescent lamps.

Claims.—(1.) A burner for incandescent or glow lamps,
composed of an internal basic filament or strip covered with
a layer of non-conducting material, and a light-giving surface
deposited thereon. (2.) A burner for an incandescent lamp,
composed of a basic non-conducting filament, having a
loosely-fitting conducting covering, designed to serve as the
light-giving portion of the burner. (3.) The method of
making burners for incandescent lamps, which consists in
properly preparing the surface of an internal non-conducting core, solid or hollow, for receiving a layer of electrically
deposited carbon, and then submitting the burner so prepared to the action of the flashing or other similar process.
(4.) A burner for incandescent lamps, consisting of a hollow
tube or cylinder of non-conducting substance, covered with
a layer of conducting material. (5.) A burner for incandescent lamps, composed of a hollow internal filament or
strip, a coating of non-conducting substance, and a layer
thereon of conducting material. (6.) A burner for incandescent lamps, composed of a properly prepared non-conducting base, and having for its light-giving portion a
composite material, composed of a mixture of conducting
and poorly-conducting substances. (7.) A burner for incandescent lamps, composed of an internal filament, a layer of
non-conducting substance, and a covering of composite-conducting material. (8.) A burner for incandescent lamps,
composed of a hollow non-conducting base, covered with a
layer of composite material formed of a mixture of conducting and non-conducting substances. (9.) A burner for incandescent lamps, having a properly prepared internal non-conducting base, upon which is deposited or coated a light-giving portion of metallic carbide. (10.) A burner for incandescent lamps, having a properly prepared internal non-conducting core, and whose light-giving portion is composed of
conducting metallic oxides. (11.) The method of making
burners for incandescent lamps, which consists in treating a
chloride of platinum with proper essential oils, applying the
resultant compound to a non-conducting basic filament,
heating the filament thus covered, and subjecting the filament thus formed to the action of an electric current in the
presence of a hydrocarbon gas or liquid.
