COMPLETE SPECIFICATION.
Improvements in Cloth-cutters.
We, JACOB PHILIPPSOHN and WILHELM LESCHZINER, both merchants of 41 Kaiser
Strasse, Berlin C., Germany 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 :—.
Our invention relates to improvements in cloth-cutters and principally to an
arrangement for protecting the person working the machine from accident by
covering that part of the cutter with an adjustable protecting disc.
In order to make our invention more clear, we refer to the accompanying drawing
in which similar letters denote similar parts throughout the several views.
Fig. 1 is a vertical section through the apparatus.
Fig. 2 is a view of the apparatus seen from underneath with the cover a removed.
Fig. 3 is an elevation of the apparatus.
Figs. 3ª and 3b show detail views of the same.
'
Figs. 4 and 4 shows a view of the protecting cap.
C is the cutter which is driven by the two bevel wheels w w¹, the one wheel w
being attached to the shaft s on which the cutter is fixed and the other wheel w¹
fixed to the shaft s¹ which runs in the hollow handle h of the apparatus.
The shaft s receives its motion from the axle st, which is connected with the
shaft s¹ in such a manner, that it is vertically adjustable on the shaft s¹ with revolving
cutter C as is necessary if the table is not perfectly smooth or if the cutting with the
apparatus is to be interrupted. Then the connection between s¹ and allows of
raising the cutter C as much as necessary.
The lower portion of the shaft s is bored out hollow and passes over the end of
shaft s; the groove g³ in s¹ is engaging with a pin or projection in the bore of the
shaft s so that one shaft can slide into the other without interferring with the rotating
motion transmitted from one shaft to the other.
To this shaft is fixed in any convenient manner a pulley which is in its turn
connected in any suitable manner with the main driving shaft. These connections
are not shown in the drawing, being unessential for the description of the
invention.
The shaft s runs in the bed plate 6 which is fixed in the frame ƒ by means of the
four screws a aaa; the bed plate b is adjustable, as the screws a a lie in slits and
not round holes.
The frame is screwed on to the tube t on which the wooden handle h is fixed.
The bevel wheels w and w¹ and bed plate are protected by the cover a which is
fastened to the frame by means of four screws V V V V.
The frame has a semi circular piece p which covers one half of the cutter C and to
this piece (fig. 1) is fixed the piece p¹ containing the foot of the apparatus f¹. The
foot is oval shaped in plan and in elevation as shown in the drawings; it has a slit
in which the cutter runs and consists of two pieces-the foot proper f¹ and then a
small plate z which is adjustably screwed on to the top of the same in order that when
the diameter of the cutter becomes smaller, the plate may be pushed forward, and
having a slit exactly corresponding to the cutter. The object of the cutter working
in the slit in the foot is to prevent any jamming of the stuff being cut which could
easily take place if the edge of the cutter worked above the foot plate instead of in
the slit. The foot f' is vertically adjustable on the frame pf of the apparatus by
means of the two screws and block 61 61 which move in the slits in the foot
piece pl.
In the top of the rim of the semi circular piece p is a slit n. The protecting cap c
lies over the upper part of the knife or cutter C and is adjustable in the slit n by
means of the screw m so that when the pile of cloth to be cut is small, the protecting

page_text: cape may be moved round in the direction of the arrow in fig. 3 until its lower edge
nearly touches the upper surface of the pile of cloth so that no part of the cutter
which revolves at a very high speed, is unprotected and thus the risk of accidents
happening is reduced to a minimum. The form of the protecting cap c may be
clearly seen from the drawing (Figs. 4 and 4º) and needs no further description.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :
In cloth-cutters :
1.) The foot of the apparatus above described in form of a tailor's iron adjustably
fixed to the frame by means of set screws, in the manner and for the purpose,
substantially as described.
2.) The combination of the foot with the adjustable plate, in the manner and
for the purpose, substantially as described.
3.) The combination of the foot f¹ with the plate and revolving cutter C, in the
manner and for the purpose, substantially as described.
4.) The combination of the foot f¹ with the plate z and revolving cutter C and
with the axle s¹, driven by the shafts by a telescopic connection, in the manner and
for the purpose, substantially as described.
5.) The combination of the foot f¹, plate z, revolving cutter C with the protecting
cap c, adjustably fixed to the frame p by means of screw m, in the manner and for the
purpose, substantially as described.
