IMPROVEMENTS IN MOUNTING CIRCULAR SAWS FOR CUTTING PILES AND ANALOGOUS OPERATIONS
Year: 1885

page_text: I, ALBERT FERDINAND LINK, of 8 Union Court, Old Broad Street, in the City
of London, Merchant, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN MOUNTING CIRCULAR SAWS FOR CUTTING PILES AND ANALOGOUS
OPERATIONS," A communication from abroad by Josef Karasek, of Elbe-Kosteletz
in the Austrian Empire, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
The object of my invention is to manufacture improved machinery or apparatus
for cutting piles or other timber under or above water or ground, or in other
positions where the ordinary apparatus is troublesome and imperfect in its
operations; such improved machinery effecting the same in a more speedy and
accurate manner than hitherto.
My invention consists essentially of an arrangement of circular saws mounted
in portable framing, with suitable driving gear, in such a manner that it can be
shifted in position, and caused to approach or recede from the work as required.
The motive power used to actuate the saws may be either manual labour,
hydraulic power, steam, air, or other suitable motive power, and applied in the
usual manner.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings.
Fig. 1 is a side elevation of my invention, shewing the same fitted to and
operating upon a pile, or other piece of timber.
Fig. 2 is a plan of the same.
Fig. 3 is an end view.
Fig. 4 is a plan view, shewing the method of attaching the collar to the timber
pile.
Figs 5, 6 and 7 are respectively side elevation, plan, and end elevation of the
invention, as arranged to cut in vertical directions.
The circular saws may be adapted to square or round timber, or other forms.
In the drawings a represents a pile or other piece of timber to be operated upon.
b is an adjustable collar, which is fixed by means of' cramps d operated upon by
Price 6d 1

page_text: the screws c.
These cramps are fitted with claws to grip the timber and prevent
slipping. The screws c are worked by, an ordinary ratchet lever, temporarily
attached to the square end of the screw.
The screws g g are used for fixing the apparatus in position, the screws c c for
fixing the claws, and the screws i i for loosening and disengaging the same.
•
The collar b carries a frame e consisting of two longitudinal girders, to which
the saws and their gear are attached. ; is a vertical post erected on a sliding
bed e¹; the upper end of this post j carries the plate h and the moveable arm h¹ is
also affixed thereto-The form of the plate h is shewn clearly in Fig. 2. are
two diagonal slots which carry the pinions and shafts of the circular saws a¹ a¹.
The plate h¹ is provided with similar slots, vertically under the slots 7, in which
the bearings and k¹, formed in two parts, are fitted.
The position of the saws, relatively to the pile to be operated upon, is adjustable
by means of set screws on the boss of h¹, whereby it is set at any suitable height
on the post j.
By means of the driving pulley n³, working in the bearings n, motion is
communicated to the shaft m, and by the bevel wheels p p the motion of m¹ is
communicated to the large wheel q, which drives the pinions r r attached to the
saw spindles m m.
•
The bearings n n are fitted to work in slots, so as to enable the large wheel q
to continue in gear with the pinions r r as the latter are moved forward to follow
_ up the saw cuts.
The automatic motion of the bed e' is effected by means of the bevel wheels ws 8 1.
and s² driving the shaft u and worm and worm wheel y actuating the screw z.
This imparts a suitable progressive motion to the frame as the saws penetrate
the timber.
After the horizontal saw-cuts have been made in one or more sides of the timber
the frame is turned in its collar through an angle of 90 degrees (more or less) when
fresh saw cuts are made, and so on until the timber is severed. In order to
accommodate the altered condition to the driving power, an additional driving
pulley n² is provided, in order to continue the driving from the same source of
power In order that vertical cuts may be made, the invention is modified as
shewn in Figs 5, 6 and 7.
In this arrangement the pillar j carries two horizontal parallel arms C C by
a cross bar C¹ and boss C fixed by a set screw. These arms support the
bearings B B, in which the saw spindle D works. A¹ A¹ are the circular saws
fitted on the spindle D.
The arms CC carry the A frames F which support the axle G, on which there
is a driving pulley Y and toothed wheel H driving the pinion wheel E on the saw
spindle D, & with it the saw A.
The saw blades are tightened by means of screws & nuts in the usual manner.
The forward motion is effected in a similar manner to that before described
for cutting horizontally, as shewn in the figures, by means of 'the bevel gear
KNN & N².
As the bed Ĺ is caused to follow the raising or lowering of the saw blades, A A,
the bearings L & L are also made adjustable.
In turning the supports through an angle of 90 degrees or thereabouts the axle M
& driving pulley J¹ is utilised as the means of imparting motion to the saws, &
other portions of the machinery.
Having now particulary described & ascertained the nature of my said
invention, & in what manner the same is to be performed, I declare that what
I claim is
1 The method of & means & appliances for working circular saws in a horizontal
or vertical position for cutting piles & analogous operations, substantially as herein
before described & shewn on the drawings.

by means of circular saws, under or above water or ground, substantially as herein
before described & shewn on the drawings.
3 The general construction, arrangement & combination of the several &
respective parts, together forming my Improvements in mounting circular saws
for cutting piles & analogous operations, substantially as herein before described
& shewn on the drawings.
