9 Claims.

This invention relates to the manufacture of pile carpets and rugs and is more particularly directed to a setting frame or machine for winding a series of yarns side by side on a receiver or spool.

In accordance with the present practice in winding a series of yarns on a receiver or spool by a setting machine or frame, a presser roll is ordinarily employed to act upon the receiver or spool and the yarn as it is wound thereon, and the pressure of the roll upon the yarn is regulated by weights and levers, or by springs connected to a sliding member which supports the presser roll. The compactness of the yarn upon the receiver or spool depends, of course, on the pressure exerted by the presser roll. The pressure on the presser roll is required to be regulated and changed from time to time to suit thevarying conditions that arise in use, and when the required amount of yarn has been wound on the receiver or spool it is necessary to disengage the presser roll from the yarn on the receiver or spool and the operator has been required to lift the presser roll by hand the required distance to remove the presser roll from the yarn on the receiver or spool, and to further provide a clearance over the yarn in order to swing the presser roll forwardly to permit removal of the wound receiver or spool. Also, when it is required to insert or engage an empty spool with its operating means, when the presserr roll is down in working position, the operator must again lift the presser roll by hand the full distance of the vertical lift.

One of the objects of the present invention is to provide means for the elimination of the labor fatigue of the operator in lifting the top roll, as

- described, and further to provide means for eX- erting amore uniform and consistent pressure of the presser roll on the winding yarn than heretofore, which uniform pressure insures a more evenly wound receiverA or spool of uniform compactness or density. A further object of the in- 4vention is to provide means for perfecting the best be made clear from the following description and accompanying drawing of one good form thereof.

The drawing presents a side elevation of a setting machine or frame embodying the present invention.

The frame I of the machine may be of any usual type for the support of the operating parts, and mounted for rotative movement on the machine frame are the operating rollers 2 and 3 for rotating the yarn receiver or spool. The operating rollers 2 and 3 may be conveniently driven from the main driving shaft 4 but the driving connection between the driving shaft and operating rollers is not herein shown because it forms no essential part of the present invention.

Mounted in suitable guides 5 is a presser roll supporting member constituted in the present instance as a slide 6 which at its upper end at 'i supports the presser roll 8 and in order that the presser roll may be swung to one side to permit the wound receiver or spool to be removed from the machine the upper portion 1 of the presser roll supporting means is pivoted at 9 to the slide B.

When the parts thus far described are in their 'operative relation the receiver or spool I!) rests upon the operating rolls 2 and 3 while the presser roll 8, as will more fully appear, presses upon the yarn receiver or spool and the yarn load as it gradually increases in amount.

Associated with the parts thus far described is a cylinder I I, shown in the present instance as located at the lower part of the machine frame, and operating in the cylinder II is a piston i2. and extending transversely of the machine or setting frame is a shaft I3 having an arm I4 affixed thereto at each side of the machine.

Connected to each of the arms I4, one at each side of the machine, is a connecting rod I 5 which at its upper end is joined at I6 to an adjustable member I1 supported by a stud I8 secured to the presser roll supporting means, the construction being such that upon movement of the arms clockwise or contra-clockwise, the presser roll supporting means will have movements imparted thereto either in a downward or an upward direction.

Secured to the transverse shaft I3 is an arm I9 having a slotted end portion 20 which is engaged at 2| with the piston rod 22, whereby movement of the piston and piston rod will be imparted to the transverse shaft I3 and through the arms I4, hereinbefore described, such movements will be imparted to the presser roll 8.

In accordance with the present invention the presser roll is to be given its desired movements through fliud pressure in the cylinder I I.

Mounted at a convenient position on the machine frame is a controlling valve 23 for controlling the fluid pressure as it comes from the source of supply through the pipe 24, and connected with the valve is the conduit or pipe 25 which communicates at 26 with the fluid pressure reduction valve 21 which may be of any of the usual forms of such valves.

Connected to the lower portion of the fluid pressure reduction valve is a pipe or conduit 28 which has the downwardly extending portion 29 connected to the cylinder II above the piston I2, the construction being such that when the control valve 23 is set for the ingress of uid pressure to and through the reduction valve 21, such pressure will be exerted above the piston I2 and perforce exert a downward pressure of the presser roll 8 upon the yarn on the receiver being wound.

Communicating with the controlling valve 23 is a conduit or pipe 30 which extends downwardly and communicates at 3I with the lower portion of the cylinder II below the piston I2, and in order that the flow of fluid pressure to and through the reduction valve 21 or to and through the pipe or conduit 30 may be controlled, the controlling valve 23 is provided with a manually operated handle or means 32.

Associated with the controlling valve 23 is an exhaust port 33 which, when the handle 32 of the controlling valve is in the full line position, as shown, will communicate with the outside atmosphere and permit pressure in the pipe or conduit 30 to exhaust. When, however, the handle 32 is moved to the dotted line position, as indicated, the exhaust port is closed and fluid pressure from the source of supply will pass through the pipe 30 to the lower part of the cylinder below the piston I2.

Connected to the upper portion of the cylinder II is a relief valve 34 of usual construction, and connected to the lower portion of the cylinder below the piston is another relief valve 35.

Assume that the yarn receiver or spool I is in position for winding, as shown, and in contact with the operating rollers 2 and 3 and the presser roll 8, and that the series of yarns a to be wound upon the receiver or spool are presented, as

usual, the piston I2 in the cylinder II will be at its lowest position, as shown, and the operating lever or handle 32 will be in the position shown by full lines in the drawing, with the result that fluid pressure will pass through the controlling valve 23 to the pressure reduction valve 21 and be admitted to the top portion of the cylinder I I above the piston, so that as the load of yarn upon the receiver or spool progresses and the yarn load increases in size the piston will be drawn upwardly by the presser roll against the fluid pressure admitted to the top of the cylinder. At this time the exhaust port 33 will be open to the atmosphere to permit the piston to rise under the dictates of the presser roll against the uid pressure.

When the required amount of yarn or yardage has been wound on the receiver or spool 4, the sett-ing frame automatically stops under the action of any of the usual automatically acting stop devices. The operator then moves the lever 32 from its full to its dotted line position, as shown. This change in the controlling valve changes and diverts the direction of fluid pressure from the source of supply through the operating valve into and through the pipe 36 to the bottom of the cylinder below the piston. This pressure, not being reduced, as was the pressure on top of the piston, forces the piston upwardly against the compression of a valve 34. As the piston continues to rise, the roller 8 also rises and when the presser roll 8 is raised away from the yarn on the receiver or spool to its highest position, as shown at the operator swings the presser roll to a position shown at y at which time the full receiver or spool may be disengaged and the next receiver or spool to be wound may be placed in contact with the operating rolls 2 and 3, whereupon the presser roll is swung back into its initial position zr.

With the empty spool in Contact with the operating rollers 2 and 3 and presser roll 8 in position at :c the operator swings the handle 32 operating the valve 23 from the dotted to the full line position which reverses the air pressure to the top of the piston and the presser roll is thereupon forced to its initial starting position, as indicated by full lines in the drawing.

As the piston is forced downwardly the action is against the compression set up by predetermined pressure in the relief valve 35, but at this point it is to be noted that the operating valve 23 connects the exhaust port 33 with the pipe 39. When the handle 32 of the controlling valve 23 is in position shown by full lines, the exhaust port 33 is open thereby preventing a vacuum under the piston when the piston is rising in the cylinder II, and also when the piston is in its up position and the handle of the controlling valve is put in its full line position and the air pressure is directed upon the top of the piston, the exhaust port being open forms an escape for the compression in the bottom of the cylinder. This is necessary because the relief valve 35 would necessarily be set to a higher pressure than enters on top of the piston through the fluid pressure reduction valve 21. When the handle 32 of the controlling valve is in dotted line position the exhaust port 33 is closed thereby allowing an initial pressure from the source of supply to pass into the pipe 3D for raising the presser roll, as previously noted.

The compression at the end of the piston stroke forms a cushion or shock absorber. Concisely stated, the pressure of the presser roll 8 on the yarn load is produced by air pressure instead of by springs or Weights, as now used, and the control of raising or lowering the presser roll 8 is at the disposition of the operator by the manipulation of the valve handle 32, so that all manual fatigue in manipulating the presser rolls is eliminated.
