In the accompanying drawing a represents a rectangular or otherwise shaped
base mounted on feets "b" and attached to a suitable bench or table. To the
front of this base is fixed a bearing "c serving as a fulcrum for a fork "d" which
is turnable secured to the bearing by the nuts "cl." The fork "d" is fitted with
a horizontal bolt "round which turns a clamp "f" that serves as abutment
for the work and for this purpose is correspondingly shaped and may
be provided with an adjustable die to fasten the work.
In the present
example the abutment consists of an angle iron. It may be adjusted
either in the horizontal plane as shown in Figure 2 by dotted lines
in the vertical level illustrated in Figure 1 or in an angle
which may be combined of both levels as shown in Figure 3 so that all admitted
mitres may be adjusted. To secure the abutment "f" in any of these positions
I have arranged a slotted bar " "which rests upon the base a and is guided
thereon by means of a slot cut into the base so that it can follow the
horizontal adjustment of the clamp "f," the vertical adjustment being obtained
by the slot "gl." Screws ", 21" serve to fix the adjusted position of the
clamp f," which may be fitted with a gage for the purpose of cutting the
moldings to the proper length.

The saw is guided by slotted posts "" which may be radially turned, raised
and lowered to operate a more or less high work without respect of the self
movement of the saw blade.
For this purpose I have fixed to the base two upright standards "/" on which

page_text: may be moved up and down sockets " m "and fixed to the standards in any position
by set screws "m¹." A round bar "n" running across the base a is fixed to the
sockets m" carrying the posts "k" which on said bar may be turned radially
and raised or lowered as shown in Figure 3 in order to cut any tenon, tooth and
the like in any mitre on the working piece.
As shown in Figure 6 I can also turn the whole saw-guiding device against the
base a by separating both parts and arranging a vertical bolt "o" allowing the
turning of the guiding device.
Figure 5 illustrates the manner in which a curved piece, for instance a tyre
portion is mitered.
For this purpose a number of slots "p" is cut into the base "a" By means
of these slots are guided angle shaped clamps 9 which may be thus arranged
and fixed to the base that they form abutments for the curved tyre piece which
may rest on the base in the positions shown in Fig. 5.
The guide post "k" is shown in Figure 1 by a vertical section. It consists of
the slotted tubular post "k" in which is guided a hollow casing "r" two vertical
rollers are arranged rotatable therein having collars "s" to receive and guide
the saw blade "t" which by means of side strips "t" passing between the rollers
engage, the collars and force the casing 1" to move up and down within the
tubular post "k."

To limit the downstroke of the saw blade I fix to the post "k" an adjustable set
angle or stop a upon which the casing comes to rest in the adjusted lowest
position.
I, GUSTAV CLEMENS, of Werlestrasse 60, Barmen, Rhenish Prussia, Germany,
Manufacturer, 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:-
The nature of my invention consists in a supporting clamp or abutment secured
to the bed plate of the machine in such a manner that it may be adjusted
together with the working piece in horizontal and vertical direction and in such
levels which may be combined of both directions.
The invention further consists in the saw guiding device which is adjustable
radially and in vertical direction so that my improved mitering machine is
adjustable to admit any sized and shaped stick molding or board and any required
nitre tenon or tooth to be operated on.
The invention consists in the combination of certain parts and details and
combinations of the same, as will be fully described hereinafter and illustrated on
the accompanying drawing filed with my Provisional Specification of May 10th
1898 of which
Figure 1 is a vertical section of the complete machine.
Figure 2 is a plan,

page_text: Figure is a plan showing a special manner of using the apparatus,
Figure 6 is a plan showing a modified arrangement of the machine.
Like letters of reference indicate corresponding parts in all figures.
In the accompanying drawing a represents a rectangular or otherwise shaped
base mounted on feet and attached to a suitable bench or table. To the
front of this base is fixed a bearing e serving as a fulcrum for a fork d which is
turnable secured to the bearing by the nuts c¹. The fork d is fitted with a
horizontal bolt e round which turns a clamp f that serves as abutment for the
work and for this purpose is correspondingly shaped. In the present example the
abutment consists of an angle iron. It may be adjusted either in the horizontal
plan as shown in Figure 2 by dotted lines or in the vertical level as illustrated in
Figure 1 or in an angle which may be combined of both levels as shown in
Figure 3 so that all admitted mitres may be adjusted. To secure the abutment f
in any of these positions I have arranged a slotted bar which rests upon the
base a and is guided thereon by means of a slot h cut into the base so that it
can follow the horizontal adjustment of the clamp f, the vertical adjustment
being obtained by the slot g'. Screws i, serve to fix the adjusted position of
the clamp f, which may be fitted with a gage for the purpose of cutting the
moldings to the proper length.
The saw is guided by slotted posts which may be radially turned raised and
lowered to operate a more or less high work without respect of the movement
of the saw blade.
For this purpose I have fixed to the base two upright standards on which
may be moved up and down sockets m and fixed to the standards in any position
by set screws m¹. A round bar n running across the base a is fixed to the socket m
carrying the posts k which on said bar may be turned radially and raised or lowered
as shown in Figure 3 in order to cut any tenon, tooth and the like in any mitre
on the working piece.
As shown in Figure 6 I can also turn the whole saw guiding device against
the base a by separating both parts and arranging a vertical bolt » allowing the
turning of the guiding device.
Figure 5 illustrates the manner in which a curved piece, for instance a tyre
portion is mitered.
For this purpose a number of slots p is cut into the base a¹. By means of these
slots are guided angle shaped clamps which may be so arranged and fixed to the
base that they form abutments for the curved tyre piece which may rest on the
base in the positions shown in Figure 5.
The guide post k is shown in Figure 1 by a vertical section. It consists of the
slotted tubular post k in which is guided a hollow casing r two vertical rollers v
are arranged rotatably therein having collars s to receive and guide the saw
bladet which by means of side strips passing between the rollers engage the
collars and force the casing r to move up and down within the tubular post k.
To limit the downstroke of the sawblade. I fix to the post an adjustable set
angle upon which the casing comes to rest in the adjusted lowest position.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
:-
First. The construction and arrangement of a machine for mitering articles of
any size texture and shape and for other similar use substantially as herein
described and delineated.
Second. The arranging and combining in a machine for mitering and similar
use of a clamp or abutment for the working piece adjustably both in vertical and
horizontal direction with a saw guiding device which may be adjusted vertically
and radially as and for the purposes herein set forth.
Third. The arranging and combining in a machine for mitering and similar use
of a clamp or abutment for the working piece adjustably both in vertical and

page_text: horizontal direction with a saw guiding device separated from the clamp base
and adjustably in horizontal vertical and radial direction as and for the purposes
herein set forth.
Fourth. In a mitering machine a base having slots or perforations for the
adjustment of a plurality of clamps or abutments in a curved line for mitering or
similar use tyre pieces and the like curved articles as and for the purposes herein
set forth.
Dated this 28th day of January in the year of our Lord One thousand eight
hundred and ninety-nine
