May 17, 1932. L. PETERSON MACHINE FOR MAKING METALAWOOL Filed Dec. 17, 1928 Patented May 17,1932

UNITED STATES PATENT.' oI-lI-Cfaz'l LEVANDER PETERSON, OF CHICAGO, ILLINOIS, ASSIGNOR T JAMES-H. RHODES &

COMPANY,OF CHICAGO, ILLINOIS, A CORPORATION 4OF ILLINOIS MACHINE ron MAKING METAL Woon Application filed December 17, 1928. Serial No. 326,491.

In the manufacture of steel wool from wire, the wire is drawn across a series of bed plates and the wool is cutl from the wire in fine strands by a series of knives positioned adjacent the bed plates in slightly spaced relation to the same.

The rate of production of the wool is of course proportionate to the rate of speed of the wire, but if the latter is increased beyond a certain point the heat generated by the cutting of the knives and the pressure of the wire against the bed plates soon results in chipping of the knives, breaking of the wire, and ignition of the wool.

The object of the present invention is to provide, in a machine for making steel wool, an improved bed plate construction which will prevent overheating of the machine and thereby permit of a substantial increase in the rate of production of the wool.

vWhile the foregoing statement is indicative in a general way of th-e nature of the invention, other objects and advantages will be apparent to those skilled in the art upon a full understanding of the construction, arrangement and operation of the improved bed plate construction.

One form of the invention is presented herein for the purpose of exemplification, but it will of course be appreciated that the invention is susceptible of embodiment in other' structurally modified forms coming equally within the scope of the appended claims.

In the accompanying drawings:

F ig. 1 is a side view of a machine constructed in accordance with the invention, certain portions being shown broken away for clearness;

Fig. 2 is a plan view of the machine; and

Fig. 3 is a detailed sectional view, taken on the line 3e-3 of Fig. l.

The machine shown in the drawings includes two vertically extending cylindrical drums and 11 which are rotatably mounted on horizontally spaced

pedestals

12 and 13. The drums, which are driven by any suitable means, are provided at regular intervals vertically thereof with shallow peripheral grooves, and the wire 14 from which the wool is cut is trained about the drums in the grooves. The wire is f-ed ati15 to the lowermost groove in thedrum 10, winds upwardly about the drums in elongated vhorizontal loops, and is removed at 16 from the uppermost groove in the drum 11. The wire'is maintained taut by any suitable means, and the area enclosed within the horizontal stretches of the wire between the drumsis occupied by a rectangular block 17 which constitutes the working bed of the machine.

Each of the faces of the block 17 along which the horizontal stretches of theV wire extend is provided with a row of vertically extending bed plates 18, and the wire '14 travels in vshallow grooves formed intiers in the outer faces of the bed plates. In Vthe particular machine shown, eight bed plates are provided at each side of the block,` but the number may be increased or Adecreased if desired. Each of the bed plates has associated therewith a vertically extending bar 19 which carries a tier of knives 201 Each of the horizontal stretches of the wire is drawn: bythe particular drum toward which it travels past the eight bed plates 18 and is out into by as many of the knives 20, the traction for the wire beingv the frictional engagement provided by the groove in the drum. The knives 2O are fastened by set-screws 21 in holders 22 which are pivoted at 23 to brackets 24 carried by the bars 19, and the depth of cut of the knives is determined by the adjustment of set

screws

25 and 26 which extend through the bars 19 and engage with the holders 22 at opposite sides of the pivotal axes thereof.

The bed plates 18 are hollow, and are preferably made in two

parts

27 and 28. The parts 27 are provided with vertically extending channels 29, while the parts 28 are detachably secured to the parts 27 at opposite sides of the channels 29 by machine bolts 30 on interposed iuidtight gaskets 31. The lower end of the channel 29 in the first bed plate at each side of the block is connected with a pipe 32, and the lower end of the channel in the last bed plate at each side of the block is connected with a pipe 33. The channels in all of the bed plates at each side of the bed are connected together in series by pipes 34. The connections described provide a tortuous passageway through the bed plates at each side of the block, and cold water or other suitable cooling medium is forced through such passageway, by any suitable means, such as a pump 35, if water under pressure is'not available, from the pipe 33 to the pipe 32 to carry off the heat developed at the bed plates and thus prevent the bed plates from becoming heated above an efcient operating temperature.

The novel bed plate construction described permits the wire to be run at a high rate of speed without danger of the wire breaking,

the Wool burning, o1' the knives chipping.

I claim:

- l. In a. machine for making metal wool from wire, a pair of horizontally spaced vertically extending grooved cylindrical drums about which a wire is wound in a number of substantially horizontal elongated loops, means for rotating the drums, a block between the drums, rows of hollow vertically extending bed plates on the sides of the block across which the wire is drawn, conduits connecting the chambers in the plates in Series, means for causing a cooling fluid to flow through the chambers in the plates, and knives arranged in vertical tiers OPPO- site' the plates for cutting the wool from the wire.

` 2. In a machine for making metal wool from wire, a bed plate consisting of a channeled member and a substantially flat member in sealed association with the channeled member over, the channel therein, means for circulatingA a coolingV fluid through the chamber between said members, means for drawing a Wire across the substantially flat membei'` of the bed plate, and means opposite the,

bed plate for cutting the wool from the wire.

In witness whereof I have hereunto subscribed my name.

LEVANDER PETERSON.
