Description

The proposed dredging machine is of the type dl. for this purpose, consisting of a rotating coil frame and a drum and a winding drum.

In the schematic drawing of FIG. 1 is a side view of the machine; FIG. 2 is a view from above.

Coils 2 are mounted on the rotating frame /. The threads, running down from the coils, each fall into a separate slot and are then assembled all together in slot 4, where the twisting of the threads actually takes place. The twisted threads pass through the slots of the oscillating lever 5, roll around the roller 6, from where they come into the box with the bar 7. The dredva is ready, smeared with barb, passes through the slots of the same lever 8, bends the roller 9 and passes through the eye 70, which is reinforced on the lever, wound onto the drum.

The action of the machine is as follows. From pulley / 2, movement is transmitted through pulleys J3, J4, J5, 16 to ba84

Face 6, on which pulleys 77, 18, 19 and 20 are mounted. From pulley 18 through pulley 27 and through conical teeth 22 and 24, the movement is transmitted to pulleys 25, 26, 27 and 25 and to pulleys 2 and 57. Each of the two last pulleys is supplied finger B2, entering the groove of the levers 5, 8 11, which creates oscillation of these levers.

The levers 3 and 5 are pivotally connected by a strap 56, into the groove of which two rods 57 are attached, attached to the box with the 7 r pitch, to transversely move this box. From the pulley 25 through the pulley 38, the frame 7 is rotated with the coils 2 mounted thereon. From the pulleys 17 to 19, the rotation is transmitted to the pulleys 39 40 through them to the wheel 9 and the pulleys 39 and 40 have eccentrically set fingers connected to the rods 42 and # 5, which, in turn, are connected to a strap sliding along the guides 44 and # 5 in translational motion and carrying a box with the bar 7 on it.

For lateral movement of the box

/ V 55339

With the bar, the end of the rope is fixed at the lower end of the lever 8. Passing through blocks 46, 47, 48 and 49, the second end of the rope is fixed to the frame of the box. Similarly arranged on the other side. When swinging the lever, the box will move along the direction. 50 bars. The drum operation is as follows. The drum is manually rotated from the handle 51 mounted on the axis of the drum. The change in its diameter is made through the handle 52, which is driven into rotation by the gear 53, sitting on the same shaft with the handle 52. This gear engages with the gear 54 to 55, which, when rotating, block the rollers 56 and 57, the roller 56 will wind a rope, which is reinforced with one end on the roller itself, and the other behind the bar 58, resting on the ratchet-mounted supports 59 and 60. The roller, winding, will carry along the ratchet 61, a number of sliders will slide over its teeth 62 between directions yuschimi 63 and 64. The slider moving the camping in the radial direction, will put pressure on several sheets of plywood and gates 65 m rasshirits them. Each sheet of plywood 65 at one end is reinforced to the bar 66, and the other end is loose.

The subject matter of the invention.

Claims (2)

1. A machine for the manufacture of a fray, consisting of a rotating coil frame and a drum for winding the choke, characterized in that a box 7 is used for the grinding of the fray, mounted on guides 44 between the bend stretch rollers 6, 9 - moved along the machine by means of crank mechanism 42, 43 connected to guide bar 50, and across the machine by flexible connections 48, each connected directly to the box 7 at one end and the lever 8 oscillating at the other end to guide roar of the draty. 2. The form of the machine according to claim 1, wherein in order to change the diameter of the drum for winding the yarn, in order to obtain pieces of different length, it is made of several sheets of plywood 65 attached each end to the planks 66 and supported by the free end on sliders 62, radially moving ratchet 61, which is rotated by means of flexible couplings attached to slats 58, supported on ratchet-mounted supports 59-60.
