This invention relates to improved means or apparatus for drying and conditioning hanks or loops of any fibrous or other materials, such as woollen, cotton, linen, jute,ha1r,

F and other yarns in machinery or apparatus of the type in which a longitudinal central drv 1g chamber arranged-en framework w n. may or may not be closed at one end between two longitudinal chambers in which are placed the heating apparatus, fans and mechanism for imparting the requisite intermittent travelling motion to the poles upon which the hanks or loops are hung.

The machine or apparatus as regards the construction of the framework, the general arrangement of the lon itudinal chambers, the heating apparatus, the fans placed in the said chamber, and mechanism for'imparting the required motion to the main movingparts of the machine may be similar to that described in the U. S. American Letters Patent No. 881602 grantedto me the Tenth day of March 1908; except the means for placing the poles in the machine; intermittently traversing the poles raising them to a higher level and delivering them arevaried, im proved and simplified by eliminating certain portions and providing means whereby a rotary motion may automatically be imparted to the poles at one or more stages of their movement. p 7 I In the drawings hereunto annexed are shown means for carrying the invention into practice. in which 7 I Fig. 1 is a part side elevation of the front end of the machine;

Like parts in all the views are marked with similar reference numerals.

1, 1 and 2 are longitudinal compartments. the central one 2 being used as a drying chamher. In the compartments 1, 1 are inserted a number of radiators or other heating apparatus 1 the heat from which is circulated and driven into the drying chamber 2 by fan 1 mounted upon shafts 1 provided with driving pulleys 1. To the inner surface of each of the longitudinal walls 3, 3, of the drying chamber 2 are fixed a number of rails 4, 4, 5, 5 composed of lengths of angle iron which form horizontal races,-hereinafter termed the lower races 4, 4, and the upper races 5, 5,upon which the poles 6 are caused to intermittently travel. The number of lower and upper races 4, 4, and 5, 5,

will vary with the number of times the hanks in line 4 of the reference 6 are required to pass through the machine before reaching the conditioning chamber 7 of the framework. In the drawings two sets only of lower races 4, 4, and upper races 5, 5, are shown at suitable distances apart and arranged on each of the two inner walls of the drying chamber 2, but the number of races to be fixed to the walls will require to be varied to correspond with the number of times that the hanks are required to be passed throughthe chamber.

The rails which form the upper and lower races 5, 5, and 4, 4, are not of the same length, the upper races 5, 5, being the longer of the two, and they also project a suitable distance beyond the lower races 4, 4, at the front end of the machine. The inner ends of both the lower and upper races 4, 4, and 5, 5, extend to a suitable distance from and within the closed end 8 of the framework of the machine.

In the two rails forming the lower races 4, 4, is or are provided one or more longitudinal gaps 9 at a suitable distance from the closet end 8 of the drying chamber 2. Each gap 9 is made of such a length that a rack 10 having spur or other teeth 11 on its upper surface may be inserted therein for imparting a rotary motion to a number-say, two or more of poles 6 as they travel over the racks. The ends of the rails-at the gapsare connected respectively to the ends of the rack. The teeth 11 of the rack 10 are clear of the inner edge of the lower races, 4, 4, as shown at Fig. 13.

The poles 6 are placed, as hereinafter described, transversely across the drying chamher 2 with each of their ends resting upon the lower races 4, 4. The central portion of each pole 6 is made of wood or other suitabie material and of a square, or round, or other cross section. On each end of a pole 6 there is fixed a metal ferrule 12circular in cross section provid-ed with a number of spur teeth 13 (Fig. 13) formed on its periphery at a suitable distance from its outer end. The teeth 13 engage with the rack 10 and impart a rotary motion to the poles 6 as the l tter are intermittently propelled along the races. The outer end of each ferrule 12 is square in cross section so as to prevent the poles 6 rotating when the spur teeth 13 are not in contact with the teeth of a rack 10.

At a suitable distance from the closed. end

8 of the drying chamber 2 and fixed to one of the vertical channel irons 14 on the outside of each side wall 3 of the drying chamber 2 is a bearing 15 for a transverse shaft 16, one end of which projects within the drying chamber 2. On the inner end of the shaft 16 is fixed a pulley 17 having a numbersay, two or moreof pieces 18 of angle iron fixed to its periphery for causing the poles 6 to travel around with the pulley 17.

A suitable guard or guide 19 is provided around and at a convenient distance from a portion of the periphery of the pulley for aiding in retaining the poles 6 in position. The guard 19 is shown in the drawings at Figs. 2 and 12 to be a continuation of the lower races 4, 4, beyond the gap 9, and the upper portion of the said guard is arranged to extend a suitable distance over the upper races 5, 5.

A separate shaft 16, pulley 17 and parts connected therewith are provided on each side of the drying chamber 2, the outer end of the shaft 16 being carried in a similar bearing 20 to the bearing 15 and fixed to one of the vertical channel irons 21 forming the outer walls 22, 22 of the machine.

A rotary motion is imparted to each shaft 16 from any convenient source of power to the fast pulley 23 mounted upon the shaft 24 (Fig. 5) carried in suitable bearings fixed to the machine framework. On the shaft 24 is mounted a cone pulley which communicates with a second cone pulley (Figs. 4 and 5) employed for communicating motion to the intermittently travelling bars 43 and 44. On the shaft 24 is mounted a worm 25 which gears with a worm wheel 26 mounted upon a transverse shaft 27 (Fig. 5).

On the shaft 27 are also mounted sprocket wheels 28, 28 which transmit the required rotary motion by means of an endless chain 29 to a second sprocket wheel 30 mounted upon the shaft 16. The outer end of each shaft 16 is geared by means of the miter wheels 31 to the longitudinal shaft 32. The shaft 32 is carried in suitable bearings 33 fixed to the outer walls 22 of the machine framework.

An intermittent motion is imparted to the poles 6 as follows At a suitable distance from each end of the lower and upper races 4, 4, and 5, 5, and on each side of the drying chamber are a pair of vertical frames 34, 34, 35, 35 (Figs.

12 and 13). Each frame 34, 35 may be made in the form of a casting or in skeleton form built up of, say, angle irons, in which provision is made for a vertical recess or opening 36 and a horizontal recess or opening 37,

both of which are respectively termed the vertical opening 36 and the horizontal opening 37. In or about the centre of the horizontal recess 37 of each vertical frame 34 or 35 is mounted, in suitable bearings 38 fixed to the framework of the machine, the

inner end of a shaft 39 which extends through and beyondthe heating and fan chambers 1, l of the machine. On the outer end of each shaft 39 is fixed bevel gearing 39 for connecting it to one of the longitudinal shafts 32. On each of the shafts 39, and in the center of the vertical frame 34, 35, are fixed a pairof cams 40, 41- of different sizes, the larger cam 40 is arranged to act against the sides 42 of the vertical opening 36 for imparting an intermittent horizontal movement thereto, and the smaller cam 41 acts upon the top and bottom portions of the said horizontal opening 37, whereby an intermittent rising and falling motion is imparted to the said frame.

To the upper and lower ends of eachpair of vertical frames 34, 35 which are arranged respectively at each side of the drying chamber 2, are fixed horizontally, angle iron bars 43, 43, 44, 44, the ends of which project a suitable distance beyond each of the said frames. The angle irons 43, 44 at the top and bottom of the vertical frames are connected together by one or more vertical rods or plates 45 which pass through guide brackets 46 fixed to the walls of the drying chamber 2.

To each of the horizontal bars 43, 44 are fixed a number of fingers 47, 48. The said fingers are so fixed to their respective bars that they project a suitable distance below the bars 43 and above the bars 44. The fingers are fixed at a suitable distancesay, for example only, at a pitch of six inches, more or lessapart for causingeach pole 6 to be intermittently moved the required distance along their respective races When the vertical frames 34,35, the bars 43, 44 and fingers 47 have been moved to their lowest position by the cam 41, the fingers 47 will then be behind the peripheries of the ferrules 12 of the poles 6 ready to cause thepoles to travel in the direction of arrow a onthe lower races 4, 4, the required distance when the frames 34, 35 are acted upon by the larger cams 40. Vfhilst the fingers 47 are in engagement with the pole 6 on the lower races 4, 4, the upper fingers 48 will then be clear of the pole 6 on the upper races 5, 5, thus allowing the last named poles to remain sta= tionary during the feeding movement of the poles on the lower races 4, 4. Afterwards when the vertical frames 34, 35 have been raised by the cams 41 for enabling the upper fingers 48 to act upon the-poles 6, which have been transferred by the pulleys 17 from the lower races 4, 4, to the upper races 5,5, the fingers 47 will then have been raised clear of the poles 6 on the lower races 4, 4. The poles 6 on the upper races 5, 5, are then moved the required distance in an opposite directionthat is, in the direction of arrow Z), to the poles on the lower races 4, 4, which are then stationary.

lower and upper bars 43, 44 are fixed thereon at or about the same distance apart, but the fingers 48 on the upper bars 44 are arranged to be at or about the centre of the spaces between each pair of fingers 47 on the lower bars 43.

The poles 6 to be fed to the lower races 2 4, 4, (Figs. 6 to 8) are placed upon the horizontal portions of angle irons 49, 49 which are respectively fixed to the framework 14 on each side of the drying chamber'2, and the said horizontal portions 49 are arranged upon a higher level than the lower races 4, 4. The said horizontal portions 49 are bent at their inner ends 50 to a suitable angle so as to deliver the poles 6, one at a time, on to the lower races 4, 4. The inclined portion of each of the said angle irons is provided with a guide plate 51 which is suitably fixed in position by any convenient means.

To an inclined stay 52which may also be formed of angle iron-are fixed brackets 53, 54. The bracket 53 connects the stay 52 to the upright 14, and the bracket 54 forms the bearing for a short spindle 55 which is fixed at right angles thereto. At the ends of the spindle 55 are fixed a pair of levers 56, 57 the lever 56 is curved and its free end-is arranged to pass through a loop 58 which is fixed to the lower intermittently reciprocating bars 43. The lever 57 is arranged with a curved end 59 which is employed for pushing the pole 6 which has been delivered on to the lower races 4, 4, into position to be acted upon by a finger 47fixed to the bars 43when the vertical frames 34, 35 and bars 43, 44 connected thereto are moved in the direction of pulley 17 which is employed for moving the poles 6 from the lower races 4, 4 to the upperraces 5, 5. W hen this movement takes place the pushing lever 57 alsoprevents the poles 6 falling out at the mouth of the inclined portions 50 whilst the said intermittent traversing motion is taking place. The poles 6 are placed by hand on the horizontal portion 49 of the angle irons at the feed end of the machine.

When the poles 6 have reached the outer ends of the upper races 5, 5, they will then have passed through the conditioning chamber 7, and they may either be arranged to be carried in a downward directionas shown at Figs. 1, 9 to 11'- or, if so desired, be carried in an upward direction on to, say, the floor of a story of a building above that in which stays to one of the uprights 14 on each side of the framework of the machine or its drying chamber 2, are employed. To the angle iron guides which form delivery inclines are fixed, by any convenient means, a number oi brackets 61 at suitable distances apart, which "form bearings for a hol ow tube 9 62 provided with a number of projecting rods or fingers 63 which are fixed to its periphery at suitable distances apart. Between each pair of rods or fingers 63 is fixed a second set 01 fingers 64 which are arranged at a different angle to the rods or fingers 63.

It will readily be understood that a rod or finger 64 is placed between each pair of rods or lingers 63.

The rods or fingers 63, 64 act as stops for regulating the descent of the poles 6 one at a time. An oscillating movement is imparted to the hollow tube 62 by a. pair of levers 65, 66 which are mounted upon a pin 67 carried by a bracket 68 fixed to one of the vertical channels 14 of the machine. The end of the lever is turned at a suit able angle to its main portion and provined with a slot 69 which engages with a. pin or rod 70. One end of the rod 70 is fixed to the oscillating tube 62. The end of lever 66 is curved and ertends in an upward direction and passes through a loop 71 fined to the u I381 intermittentl' reci rocatin l i o bar 44.

If desired the two levers 65, 66 may be formed on one boss 72, or separately mounted on the pivot pin or spindle 67 fixed to the bracket 68.

It will readily understood that there is a similar of lovers 65, 66 and parts connected ther with arranged on each side of the drying chamber 2 for delivering the poles 6.

As shown at Fig. 9, the inclined guides 60 are turned horizontally for receiving the poles 6 after they have passed down the inclined por ions from which they are removed by hand or in an other convenient manner.

When it is required to carry the poles 6 in an upward direction two sets of levers will be necessary, arranged as follows One 01": the sets of levers is employed for oscillating the tube 62 and a second set of levers for regulating the movement of the pole 6. hen this is done thehollow tube 62 will require to have a sliding, as well as an oscillating, movement imparted thereto, and in this case the tube 62 will be mounted upon a rod 7 3, the ends of which are carried by brackets 7 4, fixed respectively to one of the uprights 14 ot the machine and to a horizontal portion 7 6 of the upper delivering end or" the incline 60. Two brackets 77,

78 are employed on each side of'the drying chamber 2 and they are fixed to the uprights 14 or" the framework of the machine. The brackets 7 7 are arranged to be above the upper races 5, 5, of the machine which communicates with the inclines 60, and the other brackets 78 are arranged at a suitable distance below the said races. On a pivot pin or spindle 79 of the upper bracket 77 is arranged a lever EEO-(made in one or two parts)-the pendant portion 31 of which is below the upper races 5, 5, and it is arranged to engage alternately with pins 82 and 82 fixed to the upper intermittently reciprocating bar 44 to which the fingers 48 are fixed. The upper and longer portion of the lever is connected by a bar or rod 83 to a double ended lever 84 which is pivoted upon a pin 85 fixed to a bracket 86 secured to the undersurface of the incline 60. The opposite end of the double ended lever 84 is provided with a slot 87 of any convenient length which engages with a pin 88 secured to the tube 62. The said lovers are employed for imparting an oscillating motion to the hollow tube 62 whenever the intermittently moving part 44 is operated by the means hereinbefore described.

To the second and lower bracket 78 is pivoted a double ended lever 89 having a slot 90 at one end ior engagement with a pin 91 fixed to the moving bar 44. The lower end of the lever 89 is connected to a bar 92, provided with a bifurcated or other end 93, adapted to engage with a pin or pins 94 fixed to a collar 95 which is mounted upon the hollow sliding and oscillating tube 62. The collar 95 is retained'in position by a pair of collars 96, 96, which are fixed to the tube 62 by set screws, or other convenient means not shown in the drawings. The sliding and oscillating tube 62 is also provided with a similar arrangement of projecting rods or fingers 63 as previously described. In this instance the fingers 63 are employed for causing the poles to travel in an upward di rection, and steps 97 are provided for preventing the poles 6 descending whilst the turning movement is taking place.

The action of the levers 80, S3, 84, 89 and 92 is as follows:

WVhen the fingers 48 of the upper reciproeating bar 44 are in engagement with the poles 6 on the upper races 5, 5, and the said bars are at the extent of their forward travel. the fingers 63 of the sliding tube 62 are then in contact with the poles 6 on the inclines 60, prior to moving them in an upward direction, as shown at Fig. 15. Upon the fingers 43 and bars 44 being moved vertically by the operating cams 4lFig. 12,-to their lowest position, and then by cams 40 in a horizontal backward direction, the operating levers 89 and 92 move the tube 62, fingers 63 and the poles 6 on the inclines 60 in an upward direction. The distance of travel of the poles 6 on the inclines 60 is slightly greater than that of the poles on the races 5, 5, that is to say, levers 89 and 92 are arranged to move the poles a short distance beyond the front edge of the steps 97. Simultaneously with the said slight extra movement of the poles 6 the pin 82 fixed to the bar 44 engages with the pendant portion 81 of the lever 80. At or about the end of the backward travel of the said bar 44 the tube 62 and fingers 63, through levers 80, 88 and 84 are caused to turn out of engagement with the poles G on the inclines 60, the levers 80, 83, 84, 89 and 92 will then be in the positions shown at Fig. 15 The said poles on being released slide, the short distance before named,down the inclines until they are retained by the stops 97. The bars 44 and fingers 38 are then raised to their highest position and moved hori zontally forward carrying the poles on the upper races 5, 5, therewith. This movement, by means of levers 89 and 92, returns the sliding tube 62 and its fingers 63 to their lowest position. The movement for again turning the said fingers 63 into position behind the poles on the inclines 60 is imparted by means of the pin 82 engaging( at or about the end of the forward movement of the bar 44with the pendant portion 81 of the lever 80, the levers 80, 83, 84, 89 and 92 will then again be in the position shown at Fig. 15. The said operations can then be repeated de novo.

A convenient form of stop 97-is illustrated at Figs. 15 and 20, which may be arranged as follows To or above the upper edge of the incline 60 is arranged a plate 98' which extends nearly the full length of the said incline and is attached thereto by means of a number of hinges 99 which are fixed at suitable distances apart. On the inner surface of the plate 98 are fixed a number of stops 97 which are arranged at distances apart so as to be between the fingers 63. A leaf spring 100 may be employed for retaining the plate 98 in an upright position. The lower portion of each of the stops 97 is inclined at an angle to the inner surface of the plate 98 so as to engage with the ferrules 12 of the poles 6 as they move in an upward direction. The lower longitudinal edges of the steps 97 are arranged to taper and the front end of the said stops projects a suitable distance below the plate 98' for retaining the poles'6 in a stationary position.

In some cases in place of the leaf spring 100 a helical spring 101 20) may be employed, and its ends are connected respectively to the hinged plate 98 on each side of the drying chamber so as tc enable the two plates to be simultaneously returned to their normal position after being acted'upon by the poles 6. The said tapered edge is provided so that when a pole 6 is being moved in an upward direction by the fingers 68, the ferrules of the poles cause the plates 98 to move in an. outward direction so that they can travel along the said tapered edges for allowing the pole to pass, and as soon as the ferrule of the latter is clear or the same, the springs immediately return the stops to their normal position, thereby retaining the poles in a stationary position, thus preventing them descending whilst the turning movement of the tube 62 and fingers 63 is taking place.

In some cases it may be found more convenient to make provision for both the feeding and turning levers to be arranged above the upper intermittently reciprocating bar 44, as shown at Figs. 16 to 19. When this is done the two brackets 77, 78 will be arranged in suitable positions above the bar 44 instead of one above and one below it, and the end of the lever 92 that imparts the sliding movement to the tube 62 will be provided with a slotted pendant end 102 which engages with the pin 94 of collar 95. The lever 9-2 is pivoted to an upright 14 of the machine above the upper bar 44.

It will readily be understood that in all cases the above named levers that impart the oscillating and sliding movement are provided for each side of the machine.

When it is requiredto dry, condition, and deliver wet yarns by passing them once throughthe machine, then the hereinbefore named framework is arranged to be open at both ends, in which case the poles with wet hanks of yarn thereon are fed into the machine at one end, then caused to travel through it by the means herein described, and deliverconditioned at the opposite end. When this is done the pulley 17 which transfers the poles from the lower races 4, 4, to the upper races 5, 5, is dispensed with, and a conditioning, chamber is provided at the delivery end of the machine. One or two longitudinal sets of races are arranged in each ma chine, and the drying and conditioning chambers are arranged in longitudinal alignment.

The action of the machine is as follows The hanks having been arranged upon the poles 6 are placed by hand upon the horizontal portion 49 and allowed to slide down the incline 50 when the hooked lever 57 will have been moved so as to permit the ferruled ends of the poles 6 to pass on to the races 4, 4. The movement of the hooked portions 57 is accomplished by means of the curved levers 56 being acted upon by the reciprcating bars 43. One pole at a time is admitted on to the races 4, 4, and on the return movement of the levers 57 is pushed forward in the direction of arrow a. This operation is repeated until the poles 6 are caused to travel by the fingers 47 towards the rear end of the machine. As soon as the teeth 13 of the ferrules 12 come in contact with the teeth of the rack 10, a rotary, as well as a travelling, motion is imparted to each pole6. This rotary and travelling motion continues as long as the spur teeth of the ferrule are in mesh with the teeth of the rack. After a vpole has passed over the racks it is carried forward by the fingers 47' into a position to be acted upon by one of the brackets 18 of the pulley l? by which it is transferred from the lower races 4, 4, to the upper races 5, 5. During the said movement of the poles 6 on the lower races 4, 4, the fingers 48 fixed to the reciproeating bar 44, will be lowered out of engage ment with the poles 6 on the upper races 5, 5. The longitudinal movement of the poles 6 on either of the races will be, as previously explained, effectedby the cams 40. After the poles 6 on the lower races 4, 4, have been moved the required distance, the fingers 47 are raised clear by the cam 41, and the fingers 48 are raised so as to be in a position to move the poles 6 on the upper races 5, 5. The intermittent longitudinal reciprocating movement is continued until the poles 6. in the upper races 5, 5, reach, and pass through the conditioning chamber 7, when they are delivered either in a downward or upward direction as previously explained.

lVhen a drying chamber 2 is provided with a plurality of compartments arranged one above the other, then the front ends of the upper races 5, 5, of one compartment will require to be connected with the front ends of the lower races 4, 4, in the compartment immediately above it by end guards 19 and pulleys 17.

What I claim is p 1. Apparatus for drying yarn or other textile materials in hanks or loops having in combination a frame-work divided into three longitudinal compartments open at their front and closed at their rear, the two outer compartments having air fans and heating apparatus arranged therein, and the central chamber being employed for drying purposes, a pair of horizontal races fixed at different levels to the inner surfaces of the longitudinal walls of the drying chamber, a plurality of poles adapted to support hanks thereon placed one at a time horizontally by h and upon the lower races, each pole having a ferrule at each of its ends adapted to slide on the lower races, and also having spur teeth on its periphery adapted to engage with spur racks provided on the said races for imparting an intermittent rotary motion to the poles, means arranged within. the said chamber for intermittently propelling the poles along the upper and lower races, the poles on one of the races remaining stationary when the poles on the other races are being moved, means for raising the poles from the.
