Improvements in Ribbon Looms.
We, OTTO WALTER SCHAUM, of Corner Glenwood Avenue and Second Street, in
the City of Philadelphia, in the County of Philadelphia and State of Pennsylvania,
U.S.A., Textile Machinery Manufacturer, and ALFRED GARTNER, of the City of
Paterson, in the County of Passaic and State of New Jersey, U.S.A., Mechanical
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to ribbon looms, and its object is to simplify the con-
struction of said loom, by doing away with the heavy batten and the lay swords
supporting the same, and by providing a longitudinal reciprocating frame or rail,
on which the shuttle-blocks, the reeds, and the operating mechanism for the
shuttles are mounted.
By this arrangement the loom is greatly simplified and rendered more effective,
and can be operated at a higher speed.
The invention consists in the improved ribbon loom, its horizontally reciprocat-
ing frame or rail carrying the shuttle-blocks, reeds, and the shuttle operating
mechanism; it further consists in the means for guiding and reciprocating said
frame or rail, and in the combination and arrangement of the various parts,
substantially as will be hereinafter more fully described.
Referring to the accompanying drawing, in which like letters of reference indicate
corresponding parts in each of the several figs.:
Fig. 1, is a side elevation of a portion of a loom, provided with our improve-
ments, the loom frame being shown in dotted lines, and only such parts of the loom
are illustrated, which are necessary for a clear understanding of the invention;
Fig. 2, is an enlarged transverse sectional view of the reciprocating frame and
of the parts mounted thereon, also showing a portion of the guide rod and of a
certain operating lever;
Fig. 3, is an enlarged detail front elevation of a portion of said reciprocating rail
or frame (shown in section) and of the shuttle-blocks and intermediate reed
mounted thereon;
Fig. 4, is an enlarged top plan view of Fig. 1, the loom frame being shown in full
lines with certain portions in section; and,
Fig. 5, is a view similar to Fig. 2, illustrating a slight modification of the
reciprocating frame or rail.
In said drawing represents the loom frame, in which is journalled the main
driving shaft b and the take up roller c, in the usual and well known manner.
In suitable brackets d, e, projecting from each of the end sections of the loom
frame a, is mounted a guide-rod f, at right angles to the main driving shaft, and
secured in their respective brackets by means of set-screws, or in any desired
manner.
It may be well to remark that in the drawings there are shown only two rods f
one on each end of the loom, yet a series of intermediate rods may be arranged if.
desired, for the purpose of strengthening the construction and mechanism herein-
after described.

page_text: Upon each rod is slidingly mounted a bushing h, arranged in a sleeve i, down-
wardly projecting from and preferably integral with the rail m, which latter is
parallel with the main driving shaft and is intended to, take, the place of the
ordinary batten.
The rail illustrated in Figs. 1 to 4 inclusive consists of a flat piece of metal m',
provided at its longitudinal edges with downwardly projecting strengthening
ribs m2, m³, as clearly illustrated in Figs. 1 and 2.
On the top portion of said metallic frame or rail is secured a wooden top plate or
race way by screws or in any desired manner.
On the bevelled rear portion of said top plate or race way are mounted-at
specified intervals--the shuttle-blocks g, of the usual and well known construction
and are adjustably secured to said top plate by means of the clamps r, engaging
with their upper-bent over portions the top portions of said shuttle-blocks,
and having their lower portions hook shaped, as at 2, and in engagement with the
rail or frame m and its strengthening rib m³ respectively, all as clearly illustrated
in Fig. 2.
The pinions
are operated in the usual manner by the rack-bar o, which in the
present case is slidingly arranged in the top plate or race way n, and the reeds s
are mounted between the shuttle-blocks and upon said top plate or race way in a
manner common to ribbon looms.
Adjacent to each sleeve are downwardly projecting lugs (preferably integral
with the rail m) and are penetrated by a pin or axle, on which is loosely mounted
the bushing arranged in the forward end of the pitman, the rear portion of
which is connected with the main driving shaft or crank shaft b, in the usual
manner.
The operation is obvious from the foregoing: When the main driving shaft is
rotating, the pitmen are being operated and by their connection with the down-
wardly projecting lugs of the rail or frame m, they reciprocate the latter upon the
guide rods f, and the reeds accomplish the beating up of the weft in precisely the
same manner as in a ribbon loom, in which the batten is being oscillated.
In Fig. 5 is illustrated a modified form of a rail. Said rail is somewhat
narrower than the rail m in Fig. 2, and is provided on. its front edge with an
upwardly extending flange m, and on its longitudinal, rear edge with a downwardly
projecting strengthening rib m
On the top of said rail is secured a narrow wooden block m, in which is mounted
the rack-bar for operating the pinion, and which furnishes a base or support for
the shuttle-blocks, as clearly shown.
It must be remarked that said wooden block m needs only to be slightly
wider than the shuttle-block, as its sole functions are the supporting of said
shuttle-blocks, and the furnishing of a bearing for the reciprocating rack-bar.

Improven
We, OTTO WALTER SCHAUM, of Corner Glenwood Avenue and Second Street, in
the City of Philadelphia, in the County of Philadelphia and State of Pennsylvania.
U.S.A., Textile Machinery Manufacturer, and ALFRED GARTNER, of the City of
Paterson, in the County of Passaic and State of New Jersey, U.S.A., Mechanical
Engineer, do hereby declare the nature of this invention and in what manner the

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to ribbon looms, and its object is to simplify the con-
struction of said loom, by doing away with the heavy batten and the lay swords
supporting the same, and by providing a longitudinal reciprocating frame or rail,
on which the shuttle-blocks, the reeds, and the operating mechanism for the
shuttles are mounted.
By this arrangement the loom is greatly simplified and rendered more effective,
and can be operated at a higher speed.
The invention consists in the improved ribbon loom, its horizontally reciprocat-
ing frame or rail carrying the shuttle-blocks, reeds, and the shuttle operating
mechanism it further consists in the means for guiding and reciprocating said
frame or rail, and in the combination and arrangement of the various parts,
substantially as will be hereinafter more fully described and finally embodied in the
clauses of the claims.
Referring to the drawings filed with the Provisional Specification, in which
like letters of reference indicate corresponding parts in each of the several figs.:
Fig. 1 is a side elevation of a portion of a loom, provided with our improve-
ments, the loom frame being shown in dotted lines, and only such parts of the loom
are illustrated, which are necessary for a clear understanding of the invention;
Fig. 2 is an enlarged transverse sectional view of the reciprocating frame and
of the parts mounted thereon, also showing a portion of the guide rod and of a
certain operating lever;
Fig. an enlarged detail front elevation of a portion of said reciprocating rail
or frame (shown in section) and of the shuttle-blocks and intermediate reed
mounted thereon;
Fig. 4 an enlarged top plan view of Fig. 1, the loom frame being shown in full
lines with certain portions in section; and.
Fig. 5 a view similar to Fig. 2, illustrating a slight modification of the
Feciprocating frame or rail.
In said drawings a represents the loom frame, in which is journaled the main
driving shaft and the take up roller e, in the usual and well known manner.
In suitable brackets d, e, projecting from each of the end sections of the loom
frame, is mounted a guide-rod f, at right angles to the main driving shaft, and
secured in their respective brackets by means of set screws g, or in any desired,
manner.
It may be well to remark that in the drawings there are shown only two rods f.
one on each end of the loom, yet a series of intermediate rods may be arranged if
desired, for the purpose of strengthening the construction and mechanism herein-
after described.
Upon each rod is slidingly mounted a bushing h, arranged in a sleeve i, down-
wardly projecting from and preferably integral with the rail m, which latter is
parallel with the main driving shaft and is intended to take the place of the
ordinary batten.
The rail illustrated in Figs. 1 to 4 inclusive consists of a flat piece of metal an³,
provided at its longitudinal edges with downwardly projecting strengthening
ribs m², m³, as clearly illustrated in Figs. 1 and 2.
On the top portion of said metallic frame or rail is secured a wooden top plate or
race way by screws n¹ or in any desired manner.
On the bevelled rear portion of said top plate or race way are mounted-at
specified intervals--the shuttle blocks g. of the usual and well known construction
and are adjustably secured to said top plate by means of the clamps r, engaging
with their upper-bent over portions the top portions of said shuttle blocks,
and having their lower portions hook shaped, as at, and in engagement with the
rail or frame m and its strengthening rib m³ respectively, all as clearly illustrated
in Fig. 2.
The pinions are operated in the usual manner by the rack-bar o, which in the

page_text: present case is slidingly arranged in the top plate or race way n, and the reeds s
are mounted between the shuttle blocks and upon said top plate or raceway in a
manner common to ribbon looms.
Adjacent to each sleeve i are downwardly projecting lugs (preferably integral
with the rail m) and are penetrated by a pin or axle, on which is loosely mounted
the bushing, arranged in the forward end of the pitman, the rear portion of
which is connected with the main driving shaft or crank shaft b, in the usual
manner.
The operation is obvious from the foregoing: When the main driving shaft is
rotating, the pitmen are being operated and by their connection with the down-
wardly projecting lugs of the rail or frame m, they reciprocate the latter upon the
guide rods f, and the reeds accomplish the beating up of the weft in precisely the
same manner as in a ribbon loom, in which the batten is being oscillated.
In Fig. 5 is illustrated a modified form of a rail. Said rail is somewhat
narrower than the rail m in Fig. 2, and is provided on its front edge with an
upwardly extending flange m, and on its longitudinal rear edge with a downwardly
projecting strengthening rib m².
On the top of said rail is secured a narrow wooden block m, in which is mounted
the rack-bar for operating the pinion, and which furnishes a base or support for
the shuttle blocks, as clearly shown.
It must be remarked that said wooden block m needs only to be slightly
wider than the shuttle-block, as its sole functions are the supporting of said
shuttle-blocks, and the furnishing of a bearing for the reciprocating rack-bar.
We do not intend to limit ourselves to the precise construction shown and
described, as various alterations can be made without changing the scope of our
invention, but
Having now particularly described and ascertained the nature of our sai
invention, and in what manner the same is to be performed, we declare that what
we claim is: -
1: In a ribbon loom, a metallic rail adapted to be horizontally reciprocated
and carrying the shuttle blocks, reeds and the shuttle operating mechanism,
substantially as set forth.
2: In a ribbon loom, a metallic rail provided on its longitudinal edges with
strengthening ribs or flanges and supporting the shuttle-blocks, reeds and the
shuttle operating mechanism, said metallic rail being adapted to be horizontally
reciprocated, substantially as and for the purposes set forth.
3: In a ribbon loom, a metallic rail supporting the shuttle blocks, reeds and
shuttle operating mechanism, and means for horizontally reciprocating said
metallic rail, substantially as and for the purposes described.
4: In a ribbon loom, a metallic rail supporting the shuttle-blocks, reeds and
shuttle operating mechanism, guide rods supporting said metallic rail, and means
for reciprocating said rails upon said guide rods, substantially as and for the
purposes described.
5: In a ribbon loom, a metallic rail supporting the shuttle blocks, reeds and
the shuttle operating mechanism, sleeves projecting from said metallic rail, guide
rods penetrating said sleeves, and means for reciprocating the rail and its sleeves
upon said guide rods, substantially as and for the purposes described.
6: In a ribbon loom, a metallic rail adapted to be horizontally reciprocated,
an elongated wooden block secured to the top of said rail, shuttle blocks adjustably
mounted upon said wooden block, and means for securing said shuttle-blocks to
said wooden block and to the rail respectively, substantially as and for the purposes
described.
