1 Claim.

This invention relates to machines used in condensing and felting the hairs of fur bearing animals, particularly rabbits preparatory to the formation of bats from which felt hats are made, this being one of the several stages necessary to their construction.

An object of the invention is to provide a machine for rolling a quantity of fur, under pressure, and in opposite directions, whereby the hair strands are intermingled and matted during the passage of the fur roll therethrough.

A further feature is in the provision of a machine having a travelling conveyor, movable over a rigid horizontal bed in one direction, and a reciprocative pressure plate adjustable thereover, whereby a roll of fur entered therebetween is condensed and compacted during its passage through the machine.

These and other purposes, which will later appear, are accomplished by the novel construction, g

combination and arrangement of parts hereinafter described and illustrated in the accompanying drawings, constituting a material component of this disclosure, and in which:

Figure l is a side elevational View of an embodiment of the invention.

Figure 2 is an enlarged fragmentary view showing in detail the oscillatable spring pressure device.

Figure 3 is a similar View of the conveyor adjusting means.

Figure 4 is a vertical sectional View taken substantially on line 4-4 of Figure 6.

Figure 5 is an enlarged partial sectional View of the elements shown in Figure 2.

Figure 6 is an enlarged top plan view of the main portion of the machine, parts being shown in section.

Referring in greater detail to the drawings the numeral I5 designates a pair of upright front posts connected at their upper ends and I1 a similar pair of rear posts.

The front and rear posts are connected by lon-A gitudinal beam I9 at a convenient height from their bottoms, over which is a flooring 20, and raised from th'e flooring are side walls 2|-22, extending to the tops of the posts.

Reaching forwardly from the front posts |5 are brackets having short horizontal slots 26, alined with openings 21 spaced therefrom by lugs 28, drilled and threaded to receive screws 29, the heads of which are accessible in the openings 21 while their ends abut bearings 36 slidable in the slots 26.

Connected below the brackets 25 are inclined aprons 32 having raised side walls 33 carrying fixed bearing brackets 34. i

The rear posts |1 support a hopper 35 on their outer faces, closed at their sides 36 and rear end 31, this rear wall being inclirfed towards the body of the machine, as at 38.

The sides 36 of the hopper are extended downwardly forming brackets 39, slotted, recessed and provided with adjusting screws 40 for slidable bearings 4| in horizontal registration with the bearings 34.

Rotatably mounted in the sidewalls 2|-22 is a horizontal shaft having a pulley 46 nxed on one of its extending ends, over which is" trained a belt 41 driven by a motor 48.

On the other end of the shaft 45 is a pulley 49 driving a crossed belt 5|] trained over a pulley 5| xed on a shaft 52 mounted in the bearings 4| and provided with a roll 53 over which is trained an endless conveyor belt 54 disposed on a roll 55 xed on a shaft 56 journalled in the bearings 34, the arrangement being such that the upper run of the conveyor belt is directed towards the apron 32, as best seen in Figure 4.

Adjacent the driver pulley 46 is a sprocket wheel 58 to drive a chain 59 trained over a larger sprocket 60 xed on a shaft 6| journalled in bearings formed in the hopper sides 36 and provided with a roll 62 over which is trained another endless conveyor 64 passing over a roll 65 on a shaft 66 journalled in the bearings 30.

Closely below the upper run of the conveyor belt 64 is a rigid support plate 68 to relieve strain of weight and pressure exerted on the belt.

Fixed on the upper ends of each post |5-|1 are brackets 10 having in their upright elements pivots 1| provided with nuts 12, the pivots extending from sleeves 13.

Slidable in the sleeves are rods 14 screw threaded at their upper ends 15 to which are fitted the internally threaded hubs of hand wheels 16, and interposed between these hubs and the adjacent ends of the sleeves are coiled compression springs 11.

Below the sleeves the rods are encircled with other similar springs 18, their lower ends abutting rod terminals 19, pivoted, as at 86, to lugs 8| fixed on the upper side of a rigid plate 82 having a friction lining 83 on its under surface, which is normally parallel and spaced above the conveyor` belt 64.

Also connected by the front pivot 8|] is a clevis 84 to which is attached a rod 85 having its opposite end 86 connected by a crank pin 81 joining the elements 88 of a crank fixed midway the length of the shaft 45.

It will now be apparent that when the machine is in motion the pressure plate 82 will be moved reciprocatively lengthwise a distance controlled by the throw of the crank 88, that the movement in either direction is horizontal and that the distance between it and the conveyor belt is adjustable, while it is under constant pressure of the springs 18.

Preferably the throw of the crank is two to four inches; thus a roll of material X will be advanced by the combined action of the conveyor belt 64 and pressure plate 82 during its rearward stroke, and condensed as it is rolled back on the belt by the retrograde stroke of the'pressure plate, the roll eventually dropping into the hopper at the rear of the machine and then delivered onto the apron 32 by the lower conveyor belt 54.

Although the foregoing is descriptive of the best known embodiment of the machine, such description is not to be considered prohibitive of such changes and modications as may come within the scope of the appended claim.

What is claimed as new and sought to secure by Letters Patent, is:

In a machine for condensing fur bats, the combination with a conveyor belt constantly moving in one direction, a pressure plate movable over bats disposed on said belt, and crank actuated means for reciprocating said plate; brackets on the four upper corners of said plate, rods having hinged connections with said brackets and extending thereabove, posts having fixed brackets at their upper ends, guides for said rods swivelled in said xed brackets, said rods being threaded at their upper ends, hand wheel nuts on the threaded por-tion of said rods, compression springs interposed between said nuts and rod guides, and other compression springs interposed between said guides and said hinged connections, said rods adjustably and resiliently suspending said pressure plate.
