Here is a Patent Office description of the very early reverse
used by Geiser Mfg. Co., of Waynesboro, Pa. A picture of the engine
was shown on page 4 of the May-June issue of the ALBUM. Not many of
us understood the type of valve gear so Mr. Vic Winter mantel of
Box 4200, Bellevue, Pittsburgh 2, Pa., has gotten us this
information. Mr. Winter mantel is a popular Flour Broker as well as
a student of Valve Gears.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, Frank F, Landis, a citizen of the United
States, residing at Wayne’s borough, in the County of Franklin
and State of Pennsylvania, have invented certain new and useful
improvements in Steam – Engine Valve Gears; and I do hereby declare
the, following to be a full, clear and exact description of the
invention, Such as will enable others skilled in the art to which
it appertains to make and use same, reference being had to the
accompanying drawings, and to letters or figures of reference
marked there on, which form a. part of this specification, in
which
Figure 1 is a perspective view of my invention applied to a
portable or traction engine. Fig. 2 is a side view of the
crank-plate, showing the gearing. Fig. 3 is a view of the opposite
side of the crank-plate, showing the eccentric and pinion. Fig. 4
is a vertical section through the crank-plate, eccentric,
crank-pin, gearing, and stud. Fig. 5 shows a plan view of a
modification of my device applicable to heavy engines, in which two
bevel-pinions and a worm shaft are used in lieu of the gearing.
My invention relates more particularly to reversing mechanism
for engines; and the object of my improvements is to dispense with
the usual link-motion used for reversing the valves of engines, and
to substitute devices that consume power only when needed for
reversing the valve; and it. consists in the construction and
operation of parts hereinafter more fully set forth and
claimed.
A represents the shaft; B, the crank-plate keyed to the shaft:
P. the eccentric, fitting the hub of the crank-plate between the
crank-plate and the shaft-bearing E. The eccentric is provided on
one side of the shaft with a slot. F, through which a headed pin.
G, passes, and is seated in the crank-plate, thereby limiting the
circular movement of the eccentric. On the opposite side of the
shaft the eccentric is provided with a segmental gear, H, that
engages with the pinion, I, whose arbor J passes through the
crank-pin K and carries a, spur-wheel, L, on its outer end. The
crank-pin K is seated in the crank-plate B near its periphery, and
outside of the connecting-rod bars a flanged arm, M, that extends
to and covers an extended line of the shaft, leaving room for the
connecting rod to pass. To the lower end of this arm is attached a.
stud, N, forming an axle, upon which revolves a pulley, O, having
at all times an axis coincident with the axis of the crank-plate B.
The pulley-wheel O is held upon the stud N by a nut and washer, and
has a sleeve, P, extending inward, that carries a spur-wheel, Q,
that engages with gearwheel R, that in turn engages with wheel S,
through which connection is made with wheel L. A. cover, T, closes
down on the flange of the arm M, making a close box, securing the
wheels from dust.
A belt, U, leads from the pulley-wheel O to a band-wheel, V,
that is keyed to a short shaft that is set in a bracket on the rear
end of the boiler, within convenient reach of the driver, and is
provided with a handle attached to one of the spokes.
Inside of the bracket on the end of the short shaft is keyed a
small band-wheel, X, from which a belt h ads to, and communicates
motion to, the bevel-gearing of the governor.
The operation of my device is as follows: The machine being in
motion, the crank-plate B and pulley-wheel O receive power from the
connecting rod, and revolve around an axis common to both.
The pulley-wheel O, giving motion to the belts U W and
band-wheels V X, operates the governor. To reverse the motion of
the engine, grasp the handle and increase the speed of the
band-wheel V. This revolves the pulley-wheel O around the stud, and
through the gear-ins gives motion to arbor J, pinion I, segment H,
and revolves the eccentric D ahead of the motion of the engine as
far as the pin in the slot F will allow. This movement places the
eccentric in the correct position or relation to the crank-pin for
the reverse motion of the engine.
Having thus described my invention, I claim
1. A crank-plate, in combination with a hollow crank-pin
and arbor and a pinion, substantially as shown and described.
2. A crank-plate having a hollow crank-pin, in combination
with an eccentric, provided with a segmental gear, a pinion, an
arbor, and suitable operating mechanism, substantially as shown and
described.
3. A crank-plate having a crank-pin provided with an arm
and stud, in combination with a pulley-wheel and gearing,
substantially as shown and described.
4. A pulley-wheel, as O, attached to the crank-plate, and
revolving upon the same axis as the shaft, .substantially us shown
and described.
5. A pulley- wheel, as O, attached to the crank-plate, and
revolving upon the same axis, in combination with suitable
mechanism for operating the governor, substantially as shown and
described.
6. The pulley-wheel O, in combination with the belt U,
band-wheel V, and reverse gearing, substantially as shown and
described.
In testimony whereof I affix my signature in presence of two
witnesses.
