Fig. 5 is a section, on line 5, 5, Fig. 1,
' Patented March 23, 1909.
Serial No. 457,088.
All of the above mentioned parts may be of the usual and well known construction and form no part of my present improvements.
I will now describe my improvements.
Onthe lay sword 2 is adjustably fastened a clamp 11 on which are pivotally mounted, in this instance on opposite sides thereof, two rods 12, and 13, termed starting rods, which are adapted to move back and forth with the lay sword 2. The opposite ends of the rods 12 and 13 extend downwardly, and in a lower plane, and into annular grooves on a drum or double cam 14, which is loosely mounted on the bottom shaft 10, see Fig. 4.
. .The cam 14 is provided with the tooth portion 14, which meshes with and is driven by a gear 15 on a shaft 16, suitably mounted in a stand 17, secured to the loom side, see Fig. 1. The other end of the shaft 16 has mounted thereon agear 18, which meshes with a pinion 19 fast on the bottom shaft 10, see Fig. 4, so that the double cam 14 revolves half as fast as the bottom shaft 10, and is adapted to raise and lower the rear ends of the starting rods 12, and 13, and if one rod is down the other one is raised. As shown in the drawings, Fig. 1, the rod 12, at the front, is lowered, and on the rearward movement of the lay sword 2, the rod 12 is adapted to put the fur carrier mechanism into operation.
The lower end of a vertically extending shaft 20 has secured thereon the hub 21 of an angle lever 21; one arm of the angle lever 21 carries a roll 22, and the other arm carries a roll 28, see Fig. 4. By the rearward movement of the lay, the lower rod 12 will be ushed behind the roll 22, and move the ever 21 from the position shown by dotted lines to the position shown by full lines in Fig. 4, to revolve the vertical shaft 20 a predetermined amount in one direction. The upper end of the shaft 20 has secured thereon the hub 24 of an angle lever 24, see Figs. 1 and 2. Onearm of the angle lever 24 is connected by a rod 25 with the clutch shipper lever 26. The other arm of the lever 24 is held by the equalizing springs 27 and 27', see Fig. 2. The two equalizing sprin s 27 and 27l are ada ted to hold the vertica shaft 20 in its centra position, so that when the starting rod 12 is raised up from behind the roll 22 on the lever 21, the spring 27 will pull the vertical shaft and the angle levers thereon to their central position, and also the clutch lever 26.
As long as the vertical shaft 20 is held in position, as shown in the drawings, the clutch 28 will be held in engagement with the clutch teeth on the side of the gear 29. The gear 29 is loose on ythe main driving shaft 30 of the fur carrier mechanism, and a second gear 31 is also loose on said shaft 30.' The clutch 28 slides on a key on the shaft 30, so that said clutch will revolve with said shaft, and may be moved on said shaft into mesh with the clutch teeth on the sides of the gears 29 and 31.
As shown in Fig. 2, the clutch 28 is in mesh with the gear 29, which meshes with and drives a gear 32 mounted on the same shaft with a gear 33, which meshes with and drives a gear 34 fast to the hub of the drums 35, see Fig. 1. On the drum 35 is wound a cord 36, see Fig. l, which is secured to the fur carrier 37 Both ends of the cord 36 are secured to the drum 35, and also pass across the loom and around a sheave on the opposite side of the loom, not shown, which sheave is used as a tightener. As shown in the drawings, Fig. 3, the fur carrier in this instance starts to go from the right of the loom to the left of the loom, as indicated by the arrow in said figure.
The fur carrier mechanism herein shown is of the same construction and operation as that shown in my pending application, Serial No. 442,824.
The vertical shaft 2O has mounted thereon a lever 38, see Figs. 3, and 5, having two arms, each of Ywhich is provided with a set screw 39, adapted to be engaged by a lug 40 on one arm of a lever 40, which lever is centrally and pivotally mounted on a stud 41, on a bracket 42 secured to the loom side. The other arm of said lever 40 is connected to a rod 43, which passes loosely through the fur carrier 37 and extends across the loom.
On either end of the rod 43 is a collar 44, (only one end of the rod 43 is shown in the drawings). When the fur carrier 37 has moved through nearly its full travel, it will engage the collar 44 on the rod 43. The carrier 37 continues to move in the direction of the arrow in Fig. 3, and moves the rod 43 with it, and also operates the lever 40, having an extension 40 thereon which extends between the forked end 45 of a three-armed lever 45, see Fig. 5, which lever has its hub loosely mounted on a stud 46. The two hori- Zontally extending arms of the lever 45 are connected by rods 47, and 48, with the start ing rods 12, and 13, respectively.
By operating the lever 40 as above described, and through the operation of the lever 45 and connector 47, the end of the starting rod 12 Will be raised and disengaged from the roll 22 on the lever 21, to allow said lever 21 to move back to its central position from the action of the equalizing springs 27, and 27 and remove the clutch 28 from the gear 29 to stop the motion of the fur carrier 37. If the equalizing springs 27 and 27 fail to operate the u right shaft 2() and disengage the clutch, the ug 40 on the lever 40 will in the further movement of the fur carrier 37 engage one of the set screws 39 on the lever 38, and cause the rock shaft 20 to rock and bring the same into its central position. When the starting rod 1.3 is lowered by the action of the cam 14, and engages the roll 23 on the lever 21, every part will work in an opposite direction to that above described, and the clutch 28 of the fur carrier mechanism will move into engagement with the gear 31 said .gear 31 meshes directly with the gear 34 on the drum 35 to revolve said drum in the opposite direction, until the fur carrier 37, which is moved from the opposite end of the loom, engages the collar 44, to move the rod 43 and operate the lever 40 in the opposite direction, and cause the three-armed lever 45 to be rocked, and through the connecting rod 48 lift the starting rod 13 out of engagement with the roll 23, to stop the motion of the fur carrier 37 in the same manner as above described.
While the fur carrier is in motion, the loom has to be stopped every second pick in thel manner to be hereinafter described. As the cam 14 revolves at one-half of the speed of the bottom shaft 10, it will bring only one of the starting rods 12 and 13 into operation every second ick. lVhen either of said rods 12 and 13 is a lowed to drop it moves the inside end of a lever 50 with it, by traveling' over rolls 51 and 51 mounted on the arm of said lever, see Figs. 1, and 4. The lever 5() is loosely mounted on a stud 52, and the outer arm of said lever 50 will be raised through the connector 53 to the lever 54, and will cause the lever 54 to be raised into the position shown by the drawings. The lever 54 is pivotally mounted on an angle lever 56 which is pivotally mounted at 56. The lug 54 on said lever 54 will be engaged by a stud 55 on the lay sword 2, see Fig. 1, as the lay sword 2 moves rearwardly, and the stud 55 will move the lever 54 with it, and will also operate the angle lever 56, suitably supported to operate mechanism, not shown,to stop the loom. In order to throw the fur carrier mechanism out of operation to weave the plain heading on a finished rug, there is a shaft 57, see Figs. 1, and 4, which extends across the loom, which is operated and rocked by any ordinary means, not shown. The shaft 57 has mounted thereon the hub 5S of a lever 58, which is connected through connector 59 with the lever 50, to cause the lever 50 to be raised to lift either one of the starting rods 12 and 13,
and as long` as the starting rods are held in their raised position, they cannot start the fur carrier mechanism.
It will be understood that the details of construction of my improvements may be varied if desired.
laving thus described my invention, whatI I claim as new and desire to secure by Letters Patent is z- 1. In a loom of the class described, two levers having a reciprocating movement, a rock shaft adapted to be moved in one direction by one lever, and in the opposite direction by the other lever, mechanism for raising and lowering the ends of said levers alternately, a chenille weft or fur carrier, mechanism to operate said carrier, connections intermediate said carrier and said reciprocating` lever, to move one of said levers out of operative position, and allow the other lever to be moved into operative position.
