Q1 claim; (era- 19) U V The invention relates to apparatus for thepvalve. QTheair-admissiOn as wella s the exhaust treatment of natural and artificial silks' and velvets, more particularly as'utilized in connection with the usual boil-ofi operation o'r'dyeing' 5 operation to which these materials are subjected.

It has for an object the provision of simple and efiective means whereby'the time required for these operations may be materially reduced, as a matter of fact to less than 'onehalij the timesnow required with-types of appa'ratus'in present use.

A further object of the invention resides in the provision of apparatus of this nature wherein the use of chain blocks and othermanually actuated means for positioningthe reels'of material, dropping the same "into the vats and removing them therefrom is eliminated, and wherein all of the operations may be conducted 'inuch greater by a single operative and with expedition andconvenience. a 7

Still another object of the invention resides in the provision of apparatus whereby a pair of reels is simultaneously'treated in the vats provided therefor; and, when the desired operations are completed, whereby said reels may be quickly and readily raised out of the vats and swung into position forunloading and reloading." In carrying out the inventiorrprovision is made for suspending a pair of'reels, loaded-with the goods tobe boiled-01f or dyed,"from the "ends liquid, but when-these operations are "completed and'when thereels havebeen withdrawn from their respective vats, theymay be swung about thei'v'ertical axis of the rod'to a position 101' unloading 'or removal from the'cross he'ad;

' When a new set of reels is to-be'treated, they are first suspendedfrom the opposite ends of V a this cross-head, which is then again swung about into position to alignthe reels with the respective vats and intowhich they; are then lowered for reciprocation. .This operation of reciprocat ing the reels while immersed in theiryats is arranged to bev accomplished automatically in the provision of an air-drivenpiston forreciprocating the said rod carrying the cross-head. To this end, air is introducedbehind the' piston,

through a suitable valve, and an exhaust con-' nection is also made thereto through alfurther is arranged, not only for manual control; but

also for automatic operation from the movement the outflow of thefair so that the piston will not" descend too rapidly. 1 a I l The nature of the invention, however, will best: be understood when described in connection with the accompanying drawings,v in which:

Figi'l is a front elevation, partly in vertical;

section; showing an installationof the novel" apparatus in association with a pair'of vats.

Fig. 2 is amore or less diagrammatic view] illustrating the action 'of the valve-operating. mechanism; and Fig. 3 is a fragmentary plan. of a portion thereof. f 1

Referring to the drawings.) I0 designatesa suitable pit or well into which. alportion oithei apparatus may be sunk to, reduce the height of the same above the surfaceor'grade |l.- Upon either side of this pit arealjso sunk two tanks orvats l2 and 13, respectively, only "a portion; however, of the same being'below-grade.

Within the pit'is mounted acylinderuifa'having the piston I6 mounted forureciprofcation thereinfthere being attached to the bottom or I the piston aperforated metal bumperl-I adapt- 7 of said piston rod, or spindle. The said spindle v carries also at its extremeouter end and beyond the'cross-head 22an electric motor 23,which,' is geared, by, means .of the meshinggcars 2 4,

withthesa id cross head .22. By energizing'the motor, as by closing the starting switch 25 on panelZG; it will be appreciated that? thecrosshead-may be rotated about spindle 2G; and. reels 21' and 1 28 suspended from its-opposite ends .maythus conveniently be brought. into alignment with the vatsf-lZand. I3, into which} they are. to. be immersed as "hereinafter set PATENT? O F E51? forth. Furthermore, when the treatment of the reels containing the goods is completed, the motor may again be operated to swing the crosshead into a position such that the reels carried thereby shall be substantially at right angles had from a suitable source of air under pressure,;

as, for example, the tank 3i, Fig. 2, supplied from a motor-driven compressori -32' and through suitable valves and piping hereinafter more fully set forth. From the connection 33,

an exhaust connection 33 is taken. witha'reducing valve 34 included to suitably restrict the outflow when the piston is lowered under gravity-action so as to obviate an excessive rateof;

descent. I

. Suitable controls, both manual and automatic,

are provided for the'control of air from the said supply and exhaust connections. ter connection 33 is provided with two manual,-

1y controlled valves 35 and 36, the valve 35' having an outlet 31 directly to the atmosphere, while the outlet 38 from valve 36 connects with an automatically controlled valve 39, Fig. 3, adaptedfor exhaustinggas from behind the piston l5. pipe connection. '30, av supply connection 40 is had and in' the same is included a manually controlled valve 4| for the supply of air underpressure to the cylinder and behind the piston, said valve 41 being included in series with an automatically controlled valve 42, Fig. 2, in the line from the supply tank 3|. These various .valves are preferably locatedon the panelifi;

and by manipulatingthe same as hereinafter? set forth, various controls of the piston and at tached cross-head will be had for the'lloading, lowering and raising and'unloading of the reels.

The operation of the automatic valves 39 and 42 in order to. effect the automatic operation of periodic reciprocation of the reels, is accom plished'from the reciprocation of piston rodf29.v

To this end, there is carried by. the rod,2or

rather its flange 2|, a tappet-rod 53 having adjustably secured thereon apair of tappets 5| and 52 which are separated from each other a distance corresponding to the length of' the reciprocation desired, it being understoodthat rod 50 will partake of the reciprocation of the piston rod 20. These tappets are adapted to engage alternately with the forked end 53 of a lever secured to a rotatably mounted shaft 54.

The other end 55 of the lever ispivoted to spring toggle means embodying the oppositely acting spring-urged arms 56 and 51 and the This provides for aspring-urged arm 58. spring-toggle control wherebyjwhen the arm 55 is rocked past a horizontal position, it' will be snapped into a'location at oneside or the other of the horizontal through the action of spring-urged arm 58,'all of which is well understoodandforms no particular part of the present invention.

The shaft 54', however, has mounted there-1 over a sleeve 60 provided with a longitudinal slotGl into which extends a radially projecting pin '32 secured to the shaft; and fixedly secured to the said sleeve areoppositely extending valve operating arms-63 and 64, respectively. -These Thus, the lat- Beyond the exhaust connection to,

arms are adapted in one or the other of their positions, corresponding to the position of lever arm 55, to engage with or remain out of engagement with respective valve stems 65 and 66, respectively, of the valves 39 and 42, through corresponding laterally projecting fingers 6'! and 68 of the said arms. Thus, in one or the other of the set positions, the valve 39 will be opened for exhausting connection 38 directly to the atmosphere ,orbe shutoff; and, similarly, the valve 42 will be opened to admit air under pressure behind the piston, or the supply of air be cut off.

It will be understood that in the provision of islet Bland pin '52, a lost-motion action is involved' so thatthe arms 63 and 64 will not immediately follow the movement of arm 55 and Furthermore, provision is made to insure a holding-inbf a valve during the period that a particular cycle is taking place under its control.

vided at its ends with rollers 16, fl and 18, 19,

which are adapted {to embrace the respective fingers 6i and 68, one or the other of a pair of rollers being inv engagement with a finger, in the particular position to which it has been set, and serving thus to block undesired movement of the corresponding arm.

When theperiod of automatic reciprocation has been completed through the automatic operation hereinbefore described, and it is desired to unload the reel from the cross-head, the valve 4| may be manually operated to shut off the supply of air and the exhaust valve 35 may be similarly opened to permit direct exhausting of the airfrom behind the piston. This will cause the cross-head to descend and with it the tappet 52controlling-the exhaust. This tappet is then-loosened and-lowered to such an extent that in the subsequent elevation of'the crosshead no automatic exhausting will result through action ofthe tappet. Both exhaust valves 35 and 36 may then be shut off and the valve 4| again opened to admit air for elevating the cross-head sufficiently to swing the reels 21 and 28 clear of the'tanks i2 and I3, whereupon, by closing switch 25, the motor 23 may be operated for turning the cross-head substantially at rightangles to its previous position for unloading of the reelsand the loading on of a new set. The cross-head is thenv returned to its position wherein the ends thereof are in alignment with the tanks," and, lowered by closing of the valve:

4| and openingof exhaust valve 35. The tappet .52 is then again set for the desired position, after which the air-supply valve, 4| is opened,- the exhaust valves '35 closed and the exhaust valve 36 opened, which sets the apparatus for the. automatic. reciprocating cycle.
