Patented Apr. 9, 1940 WIRE TREATING APPARATUS Per Hakansson, Fagersta, Sweden, assignor to National Standard Company,yN1lcs, Mich., a corporation of Michigan Application September 22, 1937, Serial No. 165,067

1 Claim.

This invention relates to the manufacture of wire, and has particularly to do with cleaning, grinding, or polishing the surface of a wire.

In polishing any type of metal article, it is of great importance that the polishing medium move at high speed relatively to the surface on which it acts. This is diificult to accomplish in the preparation of wire for drawing, and usually the wire is merely drawn through a stationary polishing device, for example a device provided with emery acting on the surface of the wire.

This not only limits the speed, and has the disadvantage that the polishing is in the direction of the length of thewire, but (especially because of the tremendous lengths of wire which must be treated, and the fact that the surface is often greasy) the polishing medium quickly becomes dirty and loses some of its effect and must frezo quently be replaced. Also, in order to secure a I sufiiciently clean wire surface, it is often necessary to pass the wire through a device of this character more than once.

An object of the present invention is to im- 25 prove the cleaning (i. e., the polishing or grinding) of Wire or the like, by treating the wire with rapidly operated cleaning devices revolving around the wire as the wire is fed or drawn through the apparatus. Preferably the cleaning 30 devices are mounted on and driven by shafts or equivalent supports, arranged to revolve about the wire. Y

While grinding wheels or the like may be used as suchcleaning devices, I prefer to use 35 for most purposes cleaning belts, faced with emery or chrome oxide or the like, passing over pulleys on the shafts which revolve bodily (i. e., with a planetary motion) about the wire. However, in the case of wire coming directly from 4 a pickling operation and therefore carrying with it a corrosive material, I prefer to use brushes made of stainless steel wires. 3

The above and other objects and features of the invention, including various novel combina- 45 tions and desirable particular constructions, will be apparent from the following description of the illustrative embodiments shown in the accompanying drawing, in which:

Figure 1 is a vertical longitudinal section r0 through an apparatus utilizing cleaning belts;

Figure 2 is a partial vertical section therethrough on the line 2- -2 of Figure 1, showing the belt arrangement;

Figure 3 is a partial section, corresponding to 55 the right-hand portion of Figure 1, but showing an apparatus utilizing brushes or grindin wheels; and

Figure 4 is a partial section therethrough on the line 4-4 of Figure 3. y

In the illustrative apparatus of Figures 1 and 2, 5 a wire ID to be cleaned is drawn, by means such as a capstan l2 or the like, through a guide l4 such as a stationary sleeve mounted on the machine frame It, and through a rotatable sleeve l8 journaled in bearings carried by posts and 22 10 mounted on the frame.

The sleeve I8 is driven by means such as a belt 24 engaging fast or

loose pulleys

25 or 28 on the sleeve, and driven at a relatively high speed by means such as a motor 30. The motor 15 30 may also be connected to drive the capstan i2, at a relatively low speed, through a suitable speed-reducing gear 32.

The post 22 carries, fixed thereto on one side, a stationary gear 34 coaxial with respect to the sleeve I8. Immediately adjacent the gear 34, the sleeve !8 has secured thereto a cross-head 36 carrying at its opposite ends supports such as

rotatable shafts

38 and 40. The shaft 38 carries a pinion 42 meshing with and rolling on the 25 gear 34, and which drives the shaft as the sleeve i8 is rotated to revolve the cross-head 36.

The shafts 40 carry a series, e. g., four 1 "bout which pass cleaning belts 46, arried on opposite sides of 30 the wire .in engagement therewith as shown in Figure 2. The belts 46 may be made of strips of emery cloth or the like, to serve as polishing or cleaning devices.

In the arrangement of Figures 3 and 4, the shafts 38 and carry grinding wheels or brushes 50 which engage the wire. If brushes are used, especially for cleaning wire coming directly from a pickling operation, I-prefer to make them of wires of stainless steel (i. e., steel containing a considerable amount of chromium), so they will not corrode. Since in this case there are no belts to drive the shaft 40, I provide it with a pinion 52 which meshes with and rolls on the gear 34 the same as the pinion 42.

The apparatus of Figure 1 may, if desired, be provided with means for varying the tension of the belts 46. For example, the shaft 40 may be movably mounted in a slot 58 in the crosshead 36, and journaled in a bearing 60 carried adjustably by an adjusting screw 62 threaded through a lug on the cross-head.

The two

shafts

38 and 40 may be braced at their outer ends by a connecting plate 64 or the equivalent. Suitable means maybe provided for rigidly carried by one end of the sleeve and terminating in an outer surface substantially flush with said end of the sleeve, a. pair of parallel shafts carried by said cross-head on diametrically opposite sides of the sleeve and projecting outwardly from said outer surface, a, plurality of pulleys in abutting relationship oneach of I the shafts, a plurality of flexible endless wirecleaning belts each passing around opposite pulleys on said shafts and each arranged with its 'outer surface engaging the wire in such a manner that thebelt is entirely on one side of the wire, adjacent belts engaging the wire on opposite sides, power operated means for driving the sleeve, a stationary driving member adjacent the cross-head, a driving member carried by one of said shafts and cooperating with the stationary driving member to drive said one of the shafts and the pulleys thereon as the sleeve and crosshead are driven, a connecting plate connecting the outer ends of the shafts, and wire guiding means outside of said connecting plate, the wire being'unsupported between the sleeve and wire guiding means so that the belts can be removed and replaced by removing the connecting plate without removing the wire from the apparatus.
