COMPLETE SPECIFICATION.
An Improved Work Bench.
A communication by KARL THOMANN, of 35, Lessingstrasse, and FRIEDRICH
PETER, of 4, Metzlicherweg, both of Halle on the Saale, in the Empire of
Germany, Manufacturer and Foreman respectively.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street,
Manchester, both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, 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 relates to a work bench and has for its object to prevent accidents
during the handling of shaping tools, and to provide sure guiding devices for the
articles which are to be treated.
Figure 1 shows a side view of such a safety work bench.
Figure 2 is a longitudinal section of same:
Figure 3, a plan view of Figure 1.
Figure 4 shows the arrangement of the carriage for treating small pieces of
wood.
Figures 5 to 9 show the separate parts of the carriage.
The mode of construction of the table or bench for the various processes of
working is as follows:-
:-
The driving spindle a is arranged in a carriage c fastened to the frame 6 of the
table, this carriage being vertically adjustable by means of the device d, e, f, g, h
and i, and the spindle has at one end a driving pulley k and at the other a shaping
tool 1.
The sliding carriage n is arranged on the platform m of the bench in a dovetail
groove, on which carriage the work plate p, which also slides in dovetail guides,
may be adjusted in a longitudinal direction by means of the screw q.
In Figure 3, the work plate p is shown provided with an adjustable measuring
board or guide board A, and is arranged for shaping strips and boards, in which
case the piece which is to be shaped is laid against the measuring or guide board A,
the plate p is then suitably approached to the shaper by means of the screw
spindle 9, and the carriage n with the plate p is moved forward in the direction of
the arrow 0.
In order to prevent the piece of wood which is intended to be
shaped from slipping along the guide board, the latter is provided with projections s
which engage with the former.
The carriage, as shown in Figure 4, is employed for cutting bevels and for
treating short or small pieces of wood. In the first case, bevelling angle pieces B
are employed, which are pivotted at t and are adjustable in the slots u v. Against
the pieces B, the article to be shaped is laid and then adjusted to its required
position for the shaping tool by means of the rest w, which is capable of being
fixed. If larger pieces of wood are to be bevelled, the rest w may be pushed
further back.
If the piece of wood which is to be treated is also intended to be held down
against the work plate p, the device shown in Figure 9 is employed. The pressing
lever C, with its adjustable pressing block or cheek F, is arranged in the frame E,
which travels in the groover, and also the lever D which is held in the revolving
head G and which is provided with a pressure screw H. This device may also be
arranged in the slot
3.
If several pieces of wood placed side by side are to be shaped or bevelled
D

page_text: simultaneously, the pressure screw J, Figures 7 and 8, is employed, which enables
the separate pieces to be pressed together.
In treating curved pieces, both the carriage n and the plate p are moved in the
transverse or longitudinal direction to correspond with the actual curve of the
wood, the position of the plate p being fixed by means of the screw spindle q.
The mode of working of the safety work bench is as follows:-
The piece of wood which is to be shaped is secured to the work plate p by means
of the aforementioned devices, and this plate is moved forward with the carriage n
by the workman, in such a way that the latter does not come in the slightest
contact with the shaping tools, even when treating the smallest articles.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
1. An improved safety work bench characterised by adjustable carriages n p
having devices for holding pieces of wood or the like of various sizes and forms
which are to be worked or shaped, so that these latter need no longer be handled
by the workman, thereby preventing him from coming in contact with the shaping
tool even when operating on the smallest articles.
2. In a safety work bench such as described in Claim 1, the arrangement of a
pivoted bevelling angle piece B, Figures 5 and 6, which is adjustable in slots u v
and of a pressing device, Figures 7, 8 and 9, with the object, on the one hand, of
bevelling the piece of wood which is to be treated to any required angle, and on
the other hand of allowing even small pieces of wood to be shaped or bevelled.
Dated this 18th day of October 1893.
