This invention .relates to ,apparatus for `.Winding l ythe retaining wire ,about the rotary `druni of a continuous filter and has for `an object the provision of apparatus of the character designated which shall ,include an improved tension device `adaptedfto impart a uniform pressure onthe wire, `together withv means for manual feeding o f the wire lfor close winding on the drum and auto- Vmatic `feed `for the wire for wider spacing thereof.

A more particular object of my invention is ,to

provide a `winding machine which shall include and `means for detachably connecting the band As isv well known inthe art to which "my invention relates, the drums ofcontinuous rotary yfilters are covered witha suitable lter cloth which is retained in `place by a continuous winding of wire about the drum. Inasmuch as these i drums are of relativelylarge size, that is, several feet in diameter and in length, apparatus for `winding such drums should include means whereby a uniform tension is applied to the Wire as it v-is being wound. It is alsoimportant Athat the means for applying tension to the wire maybe These and other objects are attained by means of the apparatus illustrated in the accompanying drawings and forming a part of this application,

Referring now to Kthe drawings for a netter understanding of Vmy invention, I show in l a continuous `lter`ernbodying`a tank II). and la rotary drum I I mountedin the tank. The rotary drum I I embodies the `usual perforated cover I2 about which is placed asutable `iilter cloth I3, which is held in place on the cover by means of retaining wire i4.` As will be seen 24; `the tures. ef retaining wife are 'closely spaced adiacent .theend ofthe drum II and are more widely spaced remote from the end of the drum. Mount- Fig. `3is a rear elevation of one end ,of the feed f screw and winding mechanism; y

ed on the tank and extending parallel `to thedrum II is an I beam Iji. `At"th ends of the I beam ItV are bewiesen and Iiinfwhih is mounted for rotation a feed screw I9. Mounted onthefI beam 1l E, beneath, the feed screw l`9,`is aguide barZI.

At 2? I .Shaw a Carriage having. e base 2,3, Slidably Inounted yon `the guide bar 2Ifand including flanges 2.4 engaging beneathth guide bar- Jour',- na'lled'on the carriage `2N2 are a pair of winding Wheels 24 and Z5, Ashaftli for the Wndegwheels extends through an upwardly extending bracket 2.8,' @Heine e part 0f the Carriage Also .femme a `lJart of the carriageis a sleeve 29 which is in threaded engagement with the feed screw I9 so that as the feed screw is rotated the carriage Z2 with its winding wheels moves along the screw. Mounted in front of the winding wheels Z4 and 2,6 arengvrooved guide rollers 3l and 32 respectively. Mounted intheuprightbracket Z8, beneath the `wirlriiris wheels MI and 2.6 iS a guid bar .3311ering guide eyelets 34` and `36 therein for receiving the winding wire IIl from a SuitablereeLnQt shown. `Each strand ofthe wire I4" is passed `through one of" the eyelets 34 and 36, thence around the superposedV winding wheel-24 or Z6,

'thence under the appropriate guide roller 3| or 32 and thence to the drum I I. In stzalr-tingl the winding of a drum, the wireisisecured at one end ofthe-drum-and the drum rotated to pull the wire through the winding apparatus. i In order to apply sion.y bandl. The tensonband is anchoredlat `itskmfer .end tothe unstendine bracketl, `by

means Qfa, clanipa and'- `pin III.` Bivotally `.Irioilllted at .42.1.11 the upstandins bracket 28 `is a bell crank lever having `a .rearwardly extending longarm 43 and a short armll'l The short arm 44 of each of the bell crank levers includesan Mounted on one end of the tank I is a xbraak- A et I in which a shaft 52 is mounted f'or driving' the drum VII in a manner well understood in the art and which is not shown in detail in this drawing. On the outer end of the shaft 52vis a pinion 53 which meshes with a gear 54 mounted on a shaft 58 carried by the bracket 5I. At the rearr of the gear 54 is a sprocket 51 (shown in dotted lines). Loosely mounted on the end of the feed screw I9 (see Fig. 4) is a sprocket 58 which is connected .to the sprocket 51 by means of a chain 59. A" clutch 5I operatedby mearis of `a vlever 62 serves to engage the sprocket 58 with the feed screw yI9 to turn it from the drum l I. On the extreme outer end of the feed screw I9 is a crank 63 havinga hub B4with a slot E5 therein which is adapted to engage a pin 61 carried by the feed screw whenever it isjdesired to turn the feed (screw I9 manually. The manually operable'crank 63 is employed when the retaining wire I4 is first started to' be wound on the drum II as shown Yin Fie. 2 of the drawing, whereby the turns of wire are closely spaced with respect to each other. As soon as the first few turns of wire are applied to the drum, the clutch 6l is engaged with the sprocket 58 and thereafter the feed screw I9 is turned from lthe sprocket 51 :and the power drive for the drum] I.

From theY foregoing, it will be seen that kin lstarting the winding of a drum, the wires l are threaded vthrough the eyelets 34 and 35 in the bar `33 and are then passed around the winding wheels 24 and 26 and under the guide rollers 3i and 32` and thence to the druml l where they are secured at'one end. The tension band 38 is then wrapped around the winding wheels with the hook ends 48 engaged in the pins 41 of the bell crank lever. The weights 49 are then hooked Ionto the long arms 43 of the bell crank levers and a uniform pressure is thereby applied to the wires in the grooves 31. As the drum Il is rotated, the rwire is pulled through the winding apparatus with a uniform tension, the spacing at first being pro- `duced manually by means of the crank 63 and thereafter from the drum through the gearing,

y sprockets, and sprocket chains already described. l The band 38 is made of flexible steel and it will be seen, with the connection to the bell crank llever described, vit may be quickly attached and V,detached without necessity of bending the band and weakening it.

From the foregoing, it will be yseen that I have devised an improved winding machine for winding the rotary drums of continuous filters, which is simple and sturdy of design, reliable in operation, and one by means of which a uniform tension is 'applied to the wire being wound.
