A communication from Guhl & Harbeck, Sewing Machine Manufacturers, of
Hamburg, in the German Empire.
These improved covers for sewing-machines are constructed out of sheet iron and
are especially useful for hand or portable sewing-machines, as the covers are very
light and strong and can easily be attached to or loosened from the foot-plate of
the machine.
Each cover is constructed out of three parts of sheet iron which are soldered
together, and of which two parts form the end plates and the third part which is
bent in shape of a saddle forms the outer covering and connection between the end
plates. The end plates are furnished with an inward bent rim all round the top
and along the upright sides, and are by means of this rim and solder fastened to
the centre or saddle-plate. The outer of the cover may be varnished or painted
and ornamented as convenient.
For fastening or attaching these covers to the stand or foot plate of sewing-
machines, to the inner side of each end plate a spring catch is fastened and
corresponding square openings formed to the table or foot plate of the machine.
The cover is for the purpose of fastening placed over the machine, and is then
pressed down upon the table or foot-plate of the machine and the projecting ends
of the catches forced to hook behind the openings before mentioned. A handle for
the sake of transportation may be attached to the upper saddle part of the cover,
such handles being of common and known construction.
The loosening of the cover from the machine stand or foot-plate is effected by
pressing the catches inward by means of two outward projecting buttons, and by
lifting the cover at same time whilst pressing these buttons.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Friedrich Hermann Felix Engel in the Great Seal Patent Office on the
30th November 1881.
FRIEDRICH HERMANN FELIX ENGEL, Civil Engineer and Patent Agent, in the
City of Hamburg, Germany. "IMPROVEMENTS IN COVERS FOR SEWING MACHINES."
A communication from Guhl and Harbeck, Sewing Machine Manufacturers, of
Hamburg, in the German Empire.
This Invention relates to certain improvements in covers for sewing-machines,
which covers are constructed out of sheet metal and are especially useful for hand
or portable sewing machines as they are very light and strong and can be easily
attached to or removed or loosened from the foot-plate of the machine.
Each cover is constructed of three metal parts (sheet iron) which are soldered
together, and of which two parts form the end plates and the third part which is
bent in shape of a saddle forms the outer covering and connection between the end
plates. The end plates are furnished with an inward bent rim all around the top
and along the upright sides, and are by means of this rim and by the use of solder
fastened to the centre or saddle-plate. The outside of the cover may be varnished
or painted and ornamented as convenient.
For fastening or attaching these covers to the stand or foot plate of sewing
machines, to the inner side of each end plate a spring catch is fastened and
corresponding square openings are formed to the table or foot-plate of the machine.
The cover is for the purpose of fastening placed over the machine, and the pro-
jecting ends of the catches forced to hook behind the openings before mentioned.
A handle for facility of transport may be attached to the upper saddle part of the
cover, such handles being of common and known construction.
The loosening of the cover from the machine stand or foot-plate is effected by
pressing the catches inward by means of two outward projecting buttons, and by
lifting the cover at same time whilst pressing these buttons.
The accompanying Sheet of Drawings represents the construction and application
of this improved cover for a hand-sewing machine. Fig. 1 is a longitudinal
section through the cover and foot-plate H of the machine, and Fig. 2 is an outer
end-view of the cover showing its connection to and combination with the foot-
plate H..
The cover consists of the two end-parts A, B, and of a saddle-shaped middle
part C, which parts are all formed of sheet-iron and connected to each other by
overlapping of the edges, as shown in Fig. 1 of the Drawings.
The lower edge of the cover is strengthened by bending or folding the material,
and this edge fits to the foot-plate H of the machine, to which it is adjusted in
position by a rim formed or fastened to plate H.
The fastening of the cover to the foot-plate is ensured by spring hooks m, m³,
which catch into corresponding openings o, o¹, of foot plate H when the cover is
pressed down upon the latter. The handle G attached to the top of the cover is
used for transport of the machine when enclosed by the cover.
For loosening the cover from the machine or foot plate both spring hooks are
pressed inward by pushing the buttons p, p', attached to the hooks and projecting
through openings of the end-plates of the cover.
Sewing-machines mounted on a table and worked by a treadle are furnished
with sheet metal plates furnished with opening o, o¹, for the catches of the spring-
hooks m, m', and are inserted in and fastened to the table-plate.
Having now described the nature and particulars of the said Invention, I
claim,―
The improvements in covers for sewing machines constructed out of one saddle
shaped middle plate C and two sheet iron end-plates A, B, furnished with spring-

page_text: books that catch either into openings formed to the foot plate of the machine or to
metal plates or pieces attached to the table plate of the machine, substantially as
and for the purpose and in the manner herein described in reference to and shown
by the accompanying Sheet of Drawings.
In witness whereof, I, the said Friedrich Hermann Felix Engel, have hereunto
set my hand and seal, this Twenty sixth day of November, in the year of
our Lord One thousand eight hundred and eighty one.
