MACHINE FOR TREATING KNITTED WEBS.

Application filed April 15, 1916.

To all whom it may concern:

Be it known that I, Josnrn D. MORLEY, a citizen of the United States, residing in New York city, New York, have invented certain Improvements in Machines for Treating Knitted l Vebs, of which the following is a specification.

My invention comprises mechanism for carrying out the process of treating knitted webs set forth in my Letters Patent No. 1,181,789, dated May 2, 1916.

In the accompanying drawing-Figure 1 represents the knitted web as it appears before being treated, the longitudinal lines representing the wales of the web Fig. 2 represents the same web after a portion of the same has been treated in accordance with the process described in my previous application; Fig. 3 represents, partly in elevation and partly in longitudinal section, apparatus in accordance with my invention for carrying out said process, the dotted lines representing the web at the beginning of the treatment; Fig. 4 is a similar view representing the web at a more advanced stage of treatment; Fig. 5 is a view, partly in elevation and partly in transverse section, on the line 55, Fig. 8, and Fig. 6 is a horizontal section on the line 66, Fig.3.

The purpose of my invention above referred to was to effect the condensation of the knitted web by causing a closer disposition of the stitch wales and this purpose was accomplished by subjecting the web, preferably while hot and moist, to the action of beaters disposed transversely to the wales 0f the web and moving in the direction of said wales. In the means for carrying out said process shown in Figs. 3 and 4 of the drawing, 1 represents a hood or casing closed at one end and having at the other end a detachable head l with bearings for a pair of shafts 2 each of which carries at its inner end, within the hood, a disk 3 with a series of radially projecting arms 3 (eight in the present instance) each of these arms having near its outer end a transversely pro jecting rod 4, whereby the rods carried by each disk will be disposed in a circular se ries, the disks themselves being so disposed that the path of travel of the rods of one se ries will intersect that of the rods of the other series, as shown in Figs. 3 and 4.

The shafts 2 are suitably geared together,

as for instance by intermeshing spur wheels 7, whereby, when power is applied to one of the shafts to rotate it in one direction such power will be transmitted to the other shaft so as to rotate that shaft in the opposite direction, as indicated by the arrows in Figs. 3 and 4.

The hood 1 has therein an opening 8 so located in respect to the paths of .travel of the circular series of rods that when a free end of the web m is inserted through said opening it will cross said paths of travel where they intersect, consequently the web will be struck first on one side by a rod 4 of one series traveling in the direction of the wales of the web and then on the opposite side by a rod 4 of the other series traveling in the same direction, and this operation will be repeated by each successive pair of rods 4 as their paths of travel intersect. The rods thus have a beating action upon the web first on one side and then on the other and such action, besides effecting condensation of the web or closer disposition of the stitch wales by stretching the Web longitudinally and contracting it laterally, as shown in Fig. 2, also draws the web forwardly into the hood 1.

When the desired length of web has been subjected to the beating action said web is withdrawn from within the hood and during such withdrawal the beating action will progress along the web in a direction the reverse of that attending the introduction of the web into the hood. During the beating action the web is preferably heated and moistened by maintaining an atmosphere of wet steam within the hood 1, the steam being introduced through a pipe 9 and the accumulation of water of condensation within the hood being prevented by permitting it to leak therefrom into a drip pan 10, from which it is discharged through a drain pipe 11, or said drain pipe may be connected diportion of the hood, if desired, the drip pan 10 in this case being omitte On the head l of the hood are projecting feet 12 whereby the device may be conveniently mounted upon a work table or bench.

While I prefer to employ on each. side of the web a series of beaters, my invention in its broader aspect is not limited thereto, but could be embodied in a machine having but a single beater on each side of the web, or having the heater structure upon one side of the web only, any desired means being employed for directing a free end of the web into the path of said heater structure.

I claim:

1. The combination, in a machine for treating the end portions of knitted webs, of a beater structure, means for moving the same in the direction of the wales of the reh, and means for directing a free end of the web into the path of said beater structure, whereby the latter can act to longitudinally stretch and laterally contract that portion of the web submitted to its action.

2. The combination, in a machine for treating the end portions of knitted webs, of a plurality of heaters disposed ina circular series, means for rotating said series of heaters, and means for feeding a free end of the knitted web thereto in such manner that the heaters of the series will act successively upon said web to longitudinally stretch and laterally contract that portion of the same submitted to their action.

3. The combination, in a machine for treating the end portions of knitted webs,

of heaters disposed on opposite sides of the web, means for moving said heaters in the direction of the wales of the web, and means for feeding a free end of the knitted web between said heaters, whereby the latter will act to longitudinally stretch and laterally contract that portion of the web submitted to their action.

l. The combination, in a machine for treating the end portions of knitted webs, of heaters disposed on opposite sides of the web, means for moving said heaters in the direction of the wales of the web so that their paths of travel intersect one another, and means for feeding a free end of the knitted web thereto in such manner that it will cross said paths of travel where they intersect and will thereby be stretched longitudinally and contracted laterally.

5. The combination, in a machine for treating the end portions of knitted webs, of a plurality of heaters disposed in two circular series,means for rotating said series of heaters, and means for feeding a free end of the knitted web thereto in such manner that the successive heaters of one series will act upon one side of the web and the successive heaters of the other series will act on the opposite side of the web in alternation with the heaters of the first series, and will longitudinally stretch and laterally contract that portion of the web submitted to their action.

6. The combination, in a machine for treating the end portions of knitted webs, of aplurality of heaters disposed in two circular series, means for so rotating said heaters that where they act upon the web inclosing s'aidhe'aters they will both move in the direction of the wales of the web, and means for feeding a free end of the web to said series of heaters in such manner that the successive heaters of one series will act upon one side of the web and the successive heaters of the other series will act upon the opposite side of the web in alternation with the heaters of the first series, and will longitudinally stretch and laterally contract that portion, of the nally stretched and laterally contracted in that portion upon which the heaters act.

8. The combination, in a machine for treating knitted webs, of a heater structure, means for moving the same in the direction of the wales of the web, and a hood inclosing said heater structure and having therein an opening through which the knitted web can he passed in position to be struck by said heater structure.

9. The combination, in a machine for treating knitted webs, of a plurality of heaters disposed in a circular series, means for rotating said series of heaters in the direction of the wales of the web, and a hood inclosing said beaters and having therein an opening through which the knitted web can he passed in position to be struck by the successive heaters of the series as they rotate.

10. The combination, in a machine for treatiiig knitted webs, of heaters on opposite sides of the web, means for moving said heaters in the direction of the wales of the web, and a hood inclosing said heaters and having therein an opening through which the knitted web can he passed between the heaters. I

11. The combination, in a machine for treating knitted webs, of a plurality of heaters disposed in two circular series, means for rotating said series of heaters so that their paths of travel intersect, and a hood and having therein an opening for the introduction of the knitted web, said opening being so disposed that the introduced web will cross the paths of travel of the heaters where they intersect.

12. The combination, in a machine for treating knitted webs, of heaters for the knitted 'web movable in the direction of the wales of said web, a hood inclosing said heaters, said hood having therein an opening so disposed that the knitted Web introduced through the same Will be directed into the path of said heaters, and a steam supply pipe communicating With the interior of said hood.

13. The combination, in a machine for treating knitted Webs, of heaters for the knitted Web movable in the direction of the Wales of said Web, a hood inclosing said boaters, said hood having therein an opening so disposed that the knitted Web introduced through the same will be directed into the path of said beaters, a steam supply pipe communicating with the interior of said hood, and means for removing the Water of condensation therefrom.

14-. The combination, in a machine for treating knitted Webs, of a hood or casing having a detachable head, a beater structure disposed Within said hood, and driving mechanism for said beater structure mounted in the detachable head of the hood.

15. The combination, in a machine for treating knitted Webs, of a hood or casing closed at one end and having a detachable head at the other end, two sets of heaters Within said hood, one on one side and the other on the opposite side of the Web to be treated, and means for rotating said sets of heaters, said means having driving shafts With bearings in the detachable head of the hood.

In testimony whereof, I have signed my name to this specification, in the presence of tWo subscribing Witnesses.
