Application filed November This invention relates t-o a machine for conditioning yarn, the principal objects of which are to provide means for the continuous movement of the yarn in the machine after it is loaded; to provide means to treat it with an even spray of steam throughout its course and throughout t-he machine; to provide means in the form of a battle plate for preventing the steam to a certain extent from being discharged from the machine while the filling boxes are being loaded into it and taken out; and to provide convenient means for connecting the device with a well known form of stopping device for stopping it each time a box of yarn comes to the discharge position.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying dra-wings in which Fig. 1 is an end view of a machine embodying this invention;

Fig. 2 is a side view;

Fig. 3 is a sectional view on the line 3-3 of Fig. 2;

Fig. 4 is a sectional view on the line 4 4 of Fig. 3, and Y F ig. ,5 is a plan of a part of the stopping device.

The machine is shown as comprising a casing or frame 10 which is closed on all sides and has `an opening 11 with a door 12 for loading and unloading the machine. Inside the machine is provided with a hollow shaft 13 on which is supported the means for carrying the yarn which involves two spiders 14 in the form of spokes which carry two rings 15. Between these rings are a series of rods 16 on which are pivoted carriers 17. Each of these comprises a bottom or shelf which is held by gravity in horizontal position at all times to receive the boxes of yarn upon them and carry them around as the shaft rotates. They are connected with the rods 16 by links 18 situated on both sides of the pivot of the rods and also connected to the bottoms of the carriers at opposite sides. In this way the several carriers will assume the position shown in Fig. 3 at all times.

The shaft is hollow and is connected with a steam pipe 20 for introducing steam therein and is also provided with a series of perforated radial steam pipes 21 which are ar- PATENT OFFICE. i

ranged in several planes and are perforated throughout their areas and may be plugged at the end. These steam pipes revolve, of course, with the shaft and they produce an even spray of steam which is delivered to all the carriers which support theboxes offlling yarn deposited thereon. There is also a' stationary baie plate 22 located in position where it will not be engaged by the rotary carrier or the supports forthe filling boxes to prevent as much as possible the steam from passing out through the outlet 11 when the device is stopped for the purpose of loading or unloading.. This plate 22 is supported on arms .23 carried by necks on the shaft boxes, which necks project through the casmg.

The driving shaft 24 is operated from-` some source of power by a pulley 25 or equivalent device and it is provided rwith a clutch 26. This clutch can be pushed and closed to connect it with a shaft 27 arranged end to end with respect to the shaft 24. The shaft 27 has a worm 28 meshing with a worm wheel 29 fixed on the shaft' 13 on which the carriers are located. The method of rota-V tion therefore will be obvious. p y

The clutch is operated by a leverV 30 which is connected by a slot and pivot connection 31 with the starting rod 32. To close the clutch, the starting rod is pushed to the right in Fig. 1 by a handle on either end. y

On the shaft 27 is another worm 33 which meshes with a worm gear 34, which by a shaft drives a knock-off gear 35. knock-olf gear 35 meshes with another spur gear 36 in line with it. When the gear 35 makes a; complete revolution, a tooth 37 on each of these gears willv come into cont-act. This action pushes the gearv 36 bodily away from the gear V35, the gear 36 being mounted in a bearing on a spring pressed pivoted lever 38 for that purpose. This moves the lever 38 to the position shown in full lines in Fig. 5. This pushes a spring 40 out of engagement with a notch in the slot 39; This releases the spring 40 and allows this spring to expand against a bracket 41 on the rod 32 and push this bracket and consequently the rod to the left to release the clutch and stop the machine. This stopping mechanism by itself is called a candlestick stop motion. The result is to stop the frame and the operator then takes out a box The of yarn on the support nearest the opening 11 and replaces it by another one and then pushes the starting rod again. The operator continues to change the boxes as'the twelfth of a revolution of the drum.

-. Y In this way all the yarn is treated the same length of time so that a uniform product is secured. The yarn is thoroughly sprayed with fine steam spray all the time and very little steam is lost through the opening for loading andunloading the machine. This constitutes an accurate machine for doing this work and involves comparatively a small amount of mechanism.

Although I have illustrated and described only a single form of the invention, I am aware of. the fact that modifications can be made therein by any person skilled in the art. without departing from the scope of the invention as expressed in the claims. Also other stop motions can be substituted for the Candlestick stop motion shown. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is l; In a yarn conditioning machine,` the j combination with a casing, a horizontal shaft therein and a frame on the shaft, of a series of supports pivotally depending from the frame around its circumference for receiving the boxes of yarn to be conditioned, the shaft being hollow, means for introducing steam into the shaft and means carried by the shaft for distributing the steam in the form of jets uniformly in the casing.

2. In a yarn conditioningmachine, the combination with a casing, a horizontal shaft therein and a frame on the shaft, of a series of supports pivotally depeding from the frame around its circumference for receiving the boxes of yarn to be conditioned, the shaft being hollow, means for introducingsteam into the shaft and a plurality of series of radial pipes connected with the interior of the shaft and perforated from end to end to distribute the steam.'

L1.*In a yarn conditioning machine, the combination with a casing, a series of carriers for the yarn boxes, a series of radial perforated pipes movable with the carriers, and means for introducing steam into the pipes and projecting it in a series of fine jets at varying distances from the center from one end of the casing to the other for supplying uniform conditionsof i moisture to the yarn.

5.v In a yarn conditioning machine, the combination with a casing of a shaft located therein, a frame on said shaft and a series of supports for the yarn boxes depending from the circumference of said frame and adapted to remainV right side up as the frame rotates, said casing having an opening at one side with adoor for closing it for loading and unloading, and means for introducing steam into the frame and projecting it in a series of fine jets, and astationary baffle bach of said door'to retard the escape of steam when the door is open.

In a yarn conditioning` machine, the combination with a casing, of a shaft located therein, a frame on said shaft and a series of carriers for the yarn boxes depending from the circumference of said frame and adapted to remain right side up as thegdrum rotates, said casing having an opening at one side with va door for'closing it for loading and unloading, means for introducing steam into the frame and projecting it in a series of fine jets at varying distances from the shaft for supplying uniform conditions of moisture to 'the yarn, means for rotating said shaft slowly through a part of a revolution to bring another carrier into registration with the door, and means for then automatically stopping the frame to permit taking out one box of yarn and introducing another whereby thek yarn will all receive the vsame treatment. l

In testimony whereof I have hereunto affixed my signature.
