SHEDDING- MECHANISM FOR yLOOMS.
Specification of Letters Patent.
Patented May 2o,I 191s.
Application filed September 25, 1911. Serial No. 651,018.
scribed in Letters Patent, No. 623,114, in
which the harnesses are governed by a series of under cams and levers, in combination with a top rigging mechanism, so-termed, for moving the harnesses. The top rigging mechanism comprises a system of compound levers, and connections therefrom to the harnesses.
The object of my invention is to provide a harness evener mechanism, of simple construction and operation, and adapted to be applied to and combined with the ordinary parts of the top rigging mechanism of the type referred to, by means of which all of the harnesses may be evened, and the warps brought into the same plane for picking out, etc. After the harnesses have been evened, and if the operator fails to re-set the harnesses, I provide in this instance supplemental mechanism, which, on the starting of the loom, automatically moves the top rigging mechanism into its operating position. x
My invention consists in certain novel features of construction of my improvements as will be hereinafter fully described.
I have only shown in the vdrawings a detached portion of a loom, and the top rigging m'echanism of the type referred to, with my improvements combined therewith, suflicient to illustrate the nature thereof.
Referring to the drawings Figurel is a front view of the upper left hand portion of a loom, and the top rigging mechanism, with my improvements applied thereto. Fig. 2 corresponds to Fig. 1, but shows the opposite position of my improvements, and the harnesses evened. Fig. 3 Vis a section, on line 3, 3, Fig. 1, looking in the direction of arrow a, same figure. i
In the accompanying drawings, 1 is the loom side or end frame, 2 is the crank shaft,
8 the crank connector, which connects the crank shaft with the lay sword, not shown. 4 is the loom arch, which carries the pulleys 5, over which the harness straps 6 pass from kthe upper side of the harness frames 7.'
The harness frames 7 are operated by cams, and levers, not shown. The two straps 6 of each harness frame 7, pass separately over a pulley 5, and are then united into one, and extend to one of the strap carriers on the top rigging mechanism. t
The top rigging mechanism, which is fully shown and described in Letters Patent, No. 623,114, above referred to, consists of a main lever 8, which has its hub pivotally mounted on a stud 9, located on a stand 10,
secured on the loom arch 4. On a stud 11 on the upper end of the lever 8, are loosely mounted strap carriers, in this instance in the form of rolls 12 and 13, which are rigidly connected with each other, or made integral. To one of said rolls, as l2, is secured one end of a strap 14; the other end of said strap 14 is connected by a link 14 with two straps 6. To the other of said rolls, as 13, is secured one end of a strap 15, and the other end of said strap is connected by a link 15 to the two straps 6 of a harness frame 7. At the lower end of the lever 8 is one strap carrier, in thisinstance a roll 16, which is loosely mounted on a pin 17 ,fast in the lower end of said lever 8. The roll 16 isL in this instance prevented from turning on the stud 17 by being locked to the lever 8 by the pin 18, which enters a hole in the side ofthe pulley 19, which is made integral with the roll 16. To the roll '16 is secured one end of a strap 20; the other end of ksaid strap 2O is connected to a loop 21 carried on a stud 22V at'the upper end of an arm 23, which has its hub 23 pivotally mounted on the shaft 24 carried in a bearing 10 on the stand 10. Instead of rolls above described, carried on the lever 8, levers may be used if preferred.
Loosely mounted on the stud 22,are two rolls 25, and 26, which in this instance are made integral and turn freely on the stud 22. To one of said rolls, as 25, is secured the end of a strap 27; the other end of the strap 27 is connected by a link 27 with the double strap 6. To the other of said rolls, as l26, is secured one end of a strap 28. The other end of said strap 28 is. connected by a link 28 with the double strap 6a, which pass over the sheaves 5 of the harnesses 7, all in the usual way.
All of the above mentioned parts may be of the usual and well known construction.
I will now describe my improvements in harness evener mechanism.
The stud or pin 9 on which the lever 8 is pivotally mounted, forms in this instance a crank pin, which extends out from one side of the crank member, or disk 9, which is fast on a rotary shaft 9 which is loosely mounted in a bearing 10 on the stand l0,
see Fig. 3. The outer end of the shaft 9,
has secured thereon the hub 32 of an arm 32, which has a pin 33, to which is pivotally connected the upper end of a downwardly extending connector or rod 34. The lower end of said connector 34 is pivotally connected to a pin 35 on an arm 36, which has its hub 36 secured to the shaft 24. The opposite end of the shaft 24 has secured thereon the lhub 37 of an arm 37, which has a knob 37 at its upper end, to be manually operated. On the moving up of the arm 37 by the operator, as shown in Fig. 1, the arm 36 rests against a stop 10a on the stand 10, and is carried above its dead center, to fix the position of the crank pinr9 on which the lever 8 is mounted, and hold the lever 8, and top rigging mechanism in its operative position. rIhe moving of the lever 37, from the position shown in Fig. 1 to the position shown in Fig. 2, through connections between the arm 36 and the arm 32, will move said arm 32 downwardly until it rests upon the stop 38. The crank pin 9 is raised and moved inwardly, and causes, through the top rigging mechanism thereon, all the harness frames to be lowered and carried into the same plane, for picking out, etc. W'hen the loom is to be restarted, the operator, through the arm 37, will reset the top rigging mechanism.
In case the operator starts the loom without re-setting the top rigging mechanism, a
roll 39 on the crank connector 3, see Fig. 3, is adapted to engage a shoe 40 in its lowered position, which shoe is on the lower end of a bar 40 connected by a rod 40 with the pin 35 on the arm 36, and move upwardly said shoe to automatically move the top rigging mechanism to its operative position, through intermediate connections from the shoe 40.
It will be understood that the details of construction of my improvements may be varied if desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In shedding mechanism for loom harnesses, a system of compound levers, and connections therefrom to the harnesses, a movable fulcrum for one of said levers,
means to lock said fulcrum in its normal position, and means to unlock and to move said fulcrum, to allow the connections to the harnesses to slack, to even the harnesses and bring the warps into the same plane.
2. In shedding mechanism for looms, the combination with the harnesses, and a pivotally mounted lever having a movable fulcrum, and rocking members mounted on said lever, and connections intermediate said rocking members and said harnesses, ofvmeans for manually moving said fulcrum, to allow said connections to slack, to even the harnesses, and bring the warps into the same plane.
3. In shedding mechanism for looms, the combination with the harnesses, and a pivotally mounted lever having a movable fulcrum, and rocking members mounted on said lever, and connections intermediate said rocking members and said harnesses, of means for manually moving said fulcrum, comprising a crank member, or disk, carrying said fulcrum, and fast on a rotary shaft, and said rotary shaft mounted in a bearing on a stationary stand, and an arm fast on l said shaft, a connection on said arm to a second arm, and said second arm fast on a shaft, and said shaft, and an arm also fast on said shaft, to be manually operated t0 move said fulcrum.
