HAIR SPREADING MACHINE Application filed August's, m g a no. 383,4(81.

This invention relates to improvements in hair spreading machines, and is here shown, for example, as embodied in a machine for making carpet linings.

One of the featuresof my inventionis the provision of improved means for evenly spreading and distributing hair over a flat under-surface or lining, and then applying an upper sheet of material. The two sheets with the hair between may be then fed to a suitable sewing or quiltingmachine.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention shown in the accompanying drawings Figure 1 is a view in side elevation; Fig.

2 is a vertical sectional View; and Fig. 3 is a view in perspective showing the upper and lower lining sheets.

As shown in the drawings, A indicates a hopper into which the hair is deposited. The hopper A has tapered sides and is provided at the bottom with an elongated discharge mouth or slot A. B, .and D are picking, brushing or carding rollers provided with suitable needles, points, or bristles, depending upon the length and kind of hair. The roller B is rotated at relatively high speed, the roller C at low speed, and the roller D in the mouth preferably at a speed somewhat faster than the inclined conveyor E upon which the hair is deposited after leaving the hopper.

The conveyor E is an endless belt, or linked slots, as indicated by 10, provided with cross ribs 11, and is mounted on the two rollers 12 and 13, the latter being the driving roller and rotated in the direction indicated by the arrow.

Near the end of the conveyor, the hair is operated upon by a picking or carding roller F provided with suitable needles or points. This roller lies adjacent two cleaning or stripping bars 14 and 15 which, for example, may consist of angle irons.

At the extreme end of the conveyor is a roller brush G rotated at a relatively high speed in the direction indicated by the arrow.

Below thedischarge end of theconveyor is a platform HxWhiCli supports theunder-lining orsheet material 16u'pon' which the hair is deposited as it leaves theconveyor. "Asher-e shown, this sheet material is formed of two 5 widths of relatively narrow paper or other material with their edges overlapping, as in I .dicated by 16 The under-lining material 16 is here shown as supplied from two supply rollers 17 and 18. 0

After leaving the platform H, the sheet material 16 passes over a supporting roller 19 before passingto the sewing machine.

The upper sheet or lining material 20 is sim- L ilarly supplied from two supply rollers 21 35. and 22 from which it passes over the two rollers 23 and 24 and then is applied to the upper surface of the hair as it leaves the support H.

The details of the sewing machine form no part of the present invention. The feed rolls '6 l of a suitable sewing machine may be used, however, for moving the sheet material through my hair spreading machine. For example, 25 and 26 may indicate such feed rolls and 27, the sewing needles of the same ma- 5 chine. In Fig. 3, the rows of stitching on the completed carpet. lining are indicated by 28, 28.

The machine may be driven by a suitable motor 29 operating the counter-shaft 30 by means of the belt and pulley 31 and 32. The shaft30, by suitable belts 33 34 and 35 and pulleys 33 34 .and 35 drives the shafts 33, 34 and 35 carrying the members D, Brand F, V respectively. The shaft 30, by means of the 5 belt 36 and pulley 37 drives the shaft 38 which, in turn, carries the pulley 39 driving the belt 40, which drives the pulley 41 on the shaft 42 carrying'the conveyor drivin roller 13. The shaft 34 carries another pulley 43 on driving a belt 44 which also passes around a pulley 45 on the shaft 42. A pulley 46 on the shaft 47 carrying the member G is in frictional contact with this pulley and driven thereby. V

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modi fications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claim,

in which it is my intention to claim all novelty inherent in the invention as broadly as possible, in view of the prior art.

lVhat I regard as new, and desire to secure by Letters Patent, is: y

A picking machine of the character described, including; a hopper with tapered sides and elongated mouth; a pair of oppositely rotating picking rollers in the hopper; a picking roller in the hopper near the mouth thereof; a conveyor with its receiving 'end near the mouth of the hopper; a picking roll-, er above the conveyor near the discharge end 7 thereof; and arotating brush above the conveyor and adjacent the discharge end thereof. In witness whereof, I have hereunto set my hand this 26th day of July, 1929.
