TO WHOMIT MAY CONCERN:

Be itknown that I, Enlvsr Horrsrnnrrnn, of the city, county, and State of New York, 'have'inventeda new and useful Improvementin Machine'for Picking Hair; and I do hereby declare that the following isa full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification. I

' This invention relates to a new-and improved machine for picking hair, and cleansing it from dust and dirt. 7 And the. invention consists in the construction and arrangement of a. picker and corrugated feeder, which operate in combination with the cylinder of the machinc; and it also consists in the manner in which the. hair is fed into the machine, or construction of the feed-box, as will hereinafter be more fully described.

Figure 1 represents a sectional side elevation of the machine, the section being through the line x x of fig 2.

Figure 2 is a top orplan view of the machine.

' Similar letters of reference indicate corresponding parts A represen'ts the frame; B is the feed-box; C is the cylinder; D is the picker; E is the corrugated feeder, which turns the picker D. The shaft to which the power is applied is marked a. I). is a small wheel on this shaft, which imparts motion to the cylinder G and feeder'E, through gear-wheels and pinions, as seen in the drawing. The arrangement of the gearing is such that the'cylinder C is given a very rapid revolving motion. This cylinder is provided with teeth, and it revolves inconnection with the stationary bed or'concave-marked F, which is also provided with teeth, as seen in the drawing. This concave is formed to correspond with the circle described by the teeth of the cylinder, and the teeth in each lap by or mesh with each other.

The hair-for which this machine is especially intendediis curled hair, which has been used in upholstering, and, having become matted: together andfoul, from dustand dirt,requires picking cleaning. As the 'hair itself does'not wear out'or decay from use, it may thus be renewed and rendered nearly-or quite as valln able as new hair;

In using the machine for the purpose intended, the hair isgfirst passed through-it by being fed directly on to the cylinder, through anorifice in the feeding-box marked d. As the cylinder revolves in the direction of the arrow, the hair is carried through between the cylinderand the bed, andldischarged frohi the machine, the centrifugal force of the cylinder throwing itofi' a number of feet from the machine, scparnting'it from the dirt or heavier particles, which pass-from the bedthrough the apertures e e, or drop tothefio'or nearer the cylinder. The-operationis-repeated by passing the hair a second tin'1'e through" the machine, but this time it is more evenly fed in and thoroughly picked by being fed from the feed-box, over the end, at g, between the picker Diand the corrugated or fluted feeder E. To allow of this the coverk to the orifice d is closed, it being rep-.

resented open in the drawingns requircd'i'or the first operation; From the picker D and feeder E the hair is evenly fed on to the cylinder, and any knots or bunches of hair which may not have been thoroughly picked hythe first operation arenoiv'entirely separated, and the operation is complete.

For difi'erent kinds ofhair, adifierentpicker, D, may be uscd, as finer and coarser, and it willbe noticed that the picker is dropped .into its' bearings, and retains its position byits'own gravity. Thcpicke'r vis made of wood or othersuitable material, with metallic teeth, and the cylinder and concave are made of similur materials. The feed-box B is hinged to the frame, as seen at 0, so that access maybe had for oiling the-journals, or

other purposes. The frame and feed-box Bimay' befn'iade of either wood or iron, and the gear-wheels, and the -arbors and shafts upon which they revolve, 'are'arranged to give the required motion to the cylinder, feeder,

and picker.

I do not-confine myself to gear-wheels for giving the necessary motion tofth'e machi'ne, asI' am aware that the same maybe done by pulleys and belts.

Having thus described my invention, I claim as new, and desire totsecure by Letters Potash- The arrangement of thotoothedcylinder 0, corrugated feeder E, and removable picker D, with the hinged feed-box B, when the latter is'provided with the springs 01 h, whereby the hair is fed either between the feeder E and picker D, to the cylinder 0, or upon oneside of the feeder E,1m the cylinder, without coming in contact with the picker 1), all constructed and operatingas herein described, for'thc purposespecified.
