Improvements in Looms.
I, JAKOB FRIEDRICH HAGGENMACHER, of Zurich, Switzerland, Engineer, do hereby
declare the nature of this invention to be as follows:-
This Invention relates to looms with vertical warp, and more particularly to the
combination of two such looms with common driving gear.
In the annexed sheets of illustrative drawings,
Fig. 1 is a side elevation of a double loom in accordance with this invention.
Fig. 2 is a front elevation of the same.
Fig. 3 is a plan view.
Fig. 4 is a side elevation of the driving gear and of the changing mechanism.
Fig. 5 is a plan of the same.
'
The loom is arranged as a perfectly symmetrical double loom with a common
central driving shaft A that carries on one side a driving pulley A*.
Each side of the double loom, that is to say, each single loom S' and Shas its
movement independent of the other, that is to say each side of the double loom is
capable of being placed in or out of operation independently of the other side.
B and B are the driving shafts of the vertical looms; they have their bearings in
the frames C.
For the sake of clearness I will describe the general features of each separate
vertical loom, which however do not suparately form the subject of the present
application..
It will only be necessary to describe one loom or one half of the double loom, viz.,
that half marked with reference letters having the numeral 1. The arrangement of
the other loom which has reference letters with the nuneral 2 is of exactly similar
construction to the one I will describe.
Upon the shaft B₁ of the loom are mounted two crank pin discs D¹ the crank
pins d' of which cause the lifting rods E¹ of thei lathe. F to move up and down in
straight guides. The side slot in the lifting rod serves for the lateral movement of
the crank pind: The said slot is curved upwards to allow for the travel of the
shuttle.
In the lifting rods E¹ are carried the picking arms e' which are capable of move-
ment within certain limits. The upper or picking end of each lies in the lathe in
such a manner that the shuttle is limited in its movement by the position of the said
picking arms. The lower end is so.situated that at certain times, that is to say, when
the shuttle is to be picked or beaten, the said lower end will lie in the path of the
picking cam & one of which is situated on each disc D'.
When the pickers fare arranged exactly symmetrical on both sides, the picking
arm el on the right hand (Fig. 2) is out of engagement with the respective picking
cam, and therefore is not subject to the action thereof.
On the other or left hand side the portion of the picking arm which receives the
blow, lies in the path of the picking cam in consequence of the blow received before
by the shuttle G. The shuttle Gitself-is-guided during its passage from one position
of rest to the other, in a path below the lathe F'.
The picking arms el move with the lifting rods E' (which lift or raise the lathe F¹)
and receive on the right and on the left the blows of the picking cams S¹ which are
mounted on the equal crank discs D₁ that lift or raise the lathe.
From the warp beam K' the warp k passes over the roller supporting the warp,
through the eyelets or rings and 1ª, and then through the reed of the lathe, around
the rollers H' to the beam L¹.

shown diagrammatically since they do not form the subject of the present application,

movement of the treadle cams and shafts or leaves may be effected in any
suitable way..
In Figs. 4 and 5, an arrangement is shown by way of example, in which the
shaft M carrying the eccentrics and driven by Bf forms the shed with the aid of
cams m¹ and levers N¹.
These figures shew separately the driving gear of the two looms S' and S³, and
which is situated in the common frame C.
The bent lever W¹ serves to throw the left hand loom S' in and out of gear. This
lever is capable of movement about a pin to which is fixed in the frame C, and the
shorter arm of the lever carries one bearing of the driving shaft A. To the longer
arm of the lever is attached a brake band v' which passes over the brake pulley X
mounted on the shaft B', and is attached at the other end to a fixed point, such for
example as the frame C.
Mounted upon the brake pulley X' or keyed on one side of the same on the shaft B',
is the toothed wheel C which engages with the toothed wheel A' (correspondingly
mounted on the shaft A) as soon as the lever W' is raised.
This lever is maintained in a raised position by hanging up or fixing the
catch V¹.
When the catch V₁ is shifted, the lever W will by its own weight fall so as to
tighten the brake band X, which action is accelerated by the downward pull of the
spring 2¹
In place of the toothed wheels A', C¹, friction discs or the like may be employed.
Exactly the same device for throwing the loom S² in and out of gear is provided
on the other frame C of the double looin. The toothed wheel A² mounted on the
shaft A can be thrown into or out of gear with the toothed wheel C by the raising
or depression of the bent lever W. The same is shown thrown out of gear
in Fig. 4.
As shown in Fig. 4, the vertical loom S' would be thrown into gear, whilst the
loom S would be thrown out of gear. The crossing or twisting of the shaft A in
this position is too insignificant to cause any appreciable disadvantage.

COMPLETE SPECIFICATION.
Improvements in Looms.
I, JAKOB FRIEDRICH HAGGENMAOHER, of Zurich, Switzerland, Engineer and
Manager, 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 looms with vertical warp, and more particularly to the
combination of two such looms with common driving gear.
In the sheets of illustrative drawings filed with my Provisional Specification,
Fig. 1.is a side elevation of a double loom in accordance with this invention.
Fig. 2 is a front elevation of the same.
Fig. 3 is a plan view.
Fig. 4 is a side elevation of the driving gear and of the changing mechanism.
Fig. 5 is a plan of the same.
The loom is arranged as a perfectly symmetrical double loom with a common
central driving shaft A that carries on one side a driving pulley A*.
Each side of the double loom, that is to say, each single loom S' and S' has its
movement independent of the other, that is to say each side of the double loom is
capable of being placed in or out of operation independently of the other side.

page_text: B and B are the driving shafts of the vertical looms; they have their bearings in
the frames C.
For the sake of clearness I will describe the general features of each separate
vertical loom, which however do not separately. constitute my invention.
It will only be necessary to describe one loom or one half of the double loom, viz.,
that half marked with reference letters having the numeral 1. The arrangement of
the other loom which has reference letters with the numeral 2 is of exactly similar
construction to the one I will describe.
Upon the shaft B₁ of the loom are mounted two crank pin discs D₁ the crank pins d'
of which cause the lifting rods E¹ of the lathe F to move up and down in straight
guides. The side slot in the lifting rod serves for the lateral movement of the
crank pin d'.
In the lifting rods E' are carried the picking arms el which are capable of move-
ment within certain limits. The upper or picking end of each lies in the lathe in
such a manner that the shuttle is limited in its movement by the position of the said
picking arms. The lower end is so situated that at certain times that is to say,
when the shuttle is to be picked or beaten, the said lower end will lie in the path of
the picking cam 81 one of which is situated on each disc D'.
When the pickers and picking cams are arranged exactly symmetrical on both
sides the picking arm e' on the right hand (Fig. 2) is out of engagement with the
respective picking cam, and therefore is not subject to the action thereof.
On the other or left hand side the portion of the picking arm which receives the
blow, lies in the path of the picking cam in consequence of the blow received before
by the shuttle G. The shuttle G itself is guided during its passage from one position
of rest to the other, in a path below the lathe F¹.
The picking arms e move with the lifting rods E' (which lift or raise the lathe F¹)
and receive on the right and on the left the blows of the picking cams & which are
mounted on the equal crank discs D¹ that lift or raise the lathie.
From the warp beam K' the warp k passes over the rod supporting the warp,
through the eyelets or rings and i, and then through the reed of the lathe, around
the rollers H¹ to the beam L'.
These arrangements, together with the shuttle and the path of the shuttle, are only
shewn diagrammatically since they do not form part of the invention and only serve
to render the explanation of the invention more clear. The movement of the treadle
cams and shafts or leaves may be effected in any suitable-way--
In Figs. 4 & 5 an arrangement is shewn in which the shaft M' carrying the
eccentrics and driven by B' forms the shed with the aid of cams m' and levers N'.
These figures shew separately the driving gear of the two looms Stand S' and which
is situated in the common frame C.
The bent lever W' serves to throw the left hand loom S' in and out of gear. This lever
is capable of movement about a pin w which is fixed in the frame Cand the shorter
arm of the lever carries one bearing of the driving shaft A. To the longer arm of
the lever is attached a brake band of which passes over the brake pulley X mounted
on the shaft B and is attached at the other end to a fixed point, such for example as
the frame C.
Mounted upon the brake pulley X' or keyed on one side of the same on the shaft B'
is the toothed wheel C which engages with the toothed wheel A' (correspondingly
mounted on the shaft A) as soon as the lever W' is raised.
This lever is maintained in a raised position by hanging up or fixing the
catch V
When the catch V' is shifted the lever W¹ will by its own weight full so as to
tighten the brake band v' which action is accelerated by the downward pull of the
spring Z
In place of the toothed wheels A' (friction discs or the like may be employed.
Exactly the same device for throwing the loom S in and out of gear is provided
on the other frame of the double loom. The toothed wheel A mounted on the
shaft A can be thrown into or out of gear with the toothed wheel C² by the raising

page_text: or depression of the bent levensW. The same is: shewn thrown out of gear
in Fig. 4.
'
As shown in Fig. 4, the vertical loom S¹ would be thrown into gear, whilst the
loom S would be thrown out of gear. The crossing or twisting of the shaft A in
this position is too insignificant to cause any appreciable disadvantage.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what is
claimed in a double weavers loom having vertical chain or warp threads is :-
1. A common driving shaft A carried by two independent levers W1 & W² the
arrangement being such that by operating either lever the corresponding half loom.
can be set in action or stopped as desired."
2. The combination of the common driving shaft A carried by the two levers W
&W and fitted with gear wheels A' & A² or their equivalents with corresponding
gear wheels C & C mounted upou the loom shafts B' & B².
3. The combination with the levers W1 & W of the shaft A carrying the wheels A¹
& A the shafts B' B' with wheels CC brake discs X! X2 brake bands v' & v suspension
hooks V&V and springs Z' & Z'.
4. The combination with the levers W¹ and W of the shaft A with wheels A' & A
shafts B & B with wheels C & C brake discs X' and X' brake bands ¹ & o'
suspension hooks V&V with springs Z & Z combined with the discs [¹ & D²
