I, PHILIPPE Kooш, Manufacturer, of Neuss in the German Empire, do hereby
declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention has for its object, to simplify the mechanism for producing
the to-and-fro motion of planing machine tables, and to render it noiseless in
operation.
In the following description, reference will be made to the accompanying drawings,
in which Fig. 1 is a right hand side elevation of the principal parts of a planing
machine embodying my invention.
Fig. 2 is an end elevation of the same,
Fig. 3 a left-hand side elevation, and
Fig. 4 a plan of the same.

On shaft a, which carries the driving pulleys, is mounted a friction roller b. This
roller runs on the inside of the flange or rim of a disc or pulley c and drives the
same. This disc is mounted on a shaft d, which carries a rope pulley working in
conjunction with a rope-pulley 9 mounted at the opposite end of the machine. Over
these pulleys pass a suitable number of ropes e attached at their ends to the table of
the planing machine, which is guided in a straight line, as usual.
The ropes
may, of course, be replaced by a chain or belt, with corresponding modification of
the pulleys.
If the driving shaft a is alternately turned to the right and to the left, by
means of belts, as usual, the shaft d'will turn to the right and to the left and
produce a to-and-fro motion of the table.
In order, that the rope may be kept at the desired tension, the stationary shaft
or spindle, on which the rope-pulley 9 revolves, is held in adjustable bearings I.
These bearings are supported by an angular bracket i provided with a slot, through
which passes a screw k. The bearings carry a set-screw m which abuts against an
upward extension of flange of the bracket i.
For stretching the ropes, the screw kis first released, and then the set screw
turned forward. The bearing n for the shaft a is likewise rendered adjustable, in
order that the friction roller may be pressed more strongly against the rim of the
pulley c, when required. For this purpose, the neck of the said shaft a carries a collar
or bush o guided in a recess of the bearing n which allows the bush to slide up
and down the required distance. A pair of adjustable screws p, p are employed to
retain the bush o and shaft a in the desired position.
Having now particularly described the nature of my said invention and in what
manner the same is to be performed, I declare that what I claim is :
1. In a planing machine, the combination with the movable table guided in a
straight line, of a set of ropes, (belts or chains) attached at their ends to the said
table, a set of pulleys adapted to guide the said ropes, and means for imparting to
the ropes a to-and-fro motion, substantially as described.
2. In a planing machine having a reciprocating table propelled by ropes, the
means for imparting motion to the said ropes, comprising a flanged disc c mounted
