WILLIAM BENJAMIN GRAY, OF GLENANNE, IRELAND.

SCUTGHING-M ACHINE T 0 all whom it may concern:

Be it known that I, WVILLIAM BENJAMIN GRAY, residing at Glenanne, County Armagh, Ireland, have invented certain new and useful Improvements in Scutching-Hachines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in machines for scutching flax and other like fibers in the process of cleaning and removing the woody particles from the fiber of the class in which the fiber is held in a nip and acted upon by relatively moving bars which partially wrap the fibrous material about themselves and drag it over their edges.

The object of the invention is to construct a simple inexpensive and effective apparatus for beating and cleaning the fiber without breaking or damaging it.

Referring. to the drawings which form a part of this specification-Figure 1 is an end elevation of a machine constructed according to this invention. Fig. 2 is a front elevation of the machine. Fig. 3 is a sectional diagram showing the fiber and apron in full lines and in dotted lines the fiber and apron being passed through and over the stationary bars. Fig. 4 illustrates the movement of the bars completed to the right and about to make the return movement in the opposite direction as indicated by arrows.

According to this invention at 1 is a holder or nipping jaw for holding the fiber suspend ed to be operated upon.

At 22 are stationary cross bars carried by bridges 2* 2- and bolted to the framework 2 2 and from one of the said bars referably the higher one is suspended a iianging sheet or apron 3 of linen or other like material said sheet-or apron extending along part of the width of the machine.

At 444 are similar cross bars or beaters the ends of the latter being attached to and carried by the arms 5-5 carried by and free to rock or oscillate upon the cross shaft 6 motion being given to the arms 5 5 through the rods 7*? attached to the shaft 8 and to the eccentrics or cranks 9-9 the latter being operated through the shaft 10 by pulley 11 and strap 12 and on the shaft 10 is a fly or balance wheel 13.

The action of the machine and its operation are as folloWs:On the driving strap 12 Specification of Letters Patent.

Serial No. 425,468.

being transferred from the loose to the fast pulley the shaft 10 and eccentrics or cranks 9 by means of the connecting rods or links 77 impart to the cross shaft 8 and to the arms 5' 5 a rocking or oscillating motion on the shaft 6 whereby the cross bars 4+l4 are carried into and through the spaces between the stationary bars 22 and when by the continued movement of the bars 44 4 the fiber 14 and apron 3 have been carried clear and off the stationary bars 22 the fibers 14 and apron 3 then drop or fall into the vertical position hanging down on the opposite side of the stationary bars (see Fig. 4) ready for the return sweep of the bars f44 which will carry the fiber and apron between the bars 2-2 to their original position and so on at each sweep of the moving bars l 44 the fiber 14 and apron 3 are passed and repassed from left to right through the grating formed by the stationary bars 2-2 until through the beating and rubbing action of the movable bars 4 4a upon the fiber 14 the desired result and effect are attained. The apron 3 operates as a retarder or brake upon the fiber by preventing the too easy and smooth passage way of the fiber through the bars and insures the requisite beating and rubbing action of the bars upon the fiber.

in practice I find that a reciprocating speed of from to 80 beats per minute effects the desired result and it will be under stood that the length or radius of the sweep of the moving bars can be adjusted according to the length of staple of the fiber being 0 eratcd upon by varying the height of t re shaft 8 in the slots 15*15 in the arms 5-5. So likewise the form in cross section of the movable and fixed bars may be varied but the section shown in the drawings I have found well adapted for the purpose and use designed or the sheet or apron 3 may be attached to one or other of the movable bars ll4.

In Fig. 2 I have shown one holder 1 and a short length of apron 3 only but it will be understood that nearly the whole of the operating length of the bars 2 and 4 is occupied by the holders 1 the fiber 14 and the apron 3. The width to be occupied by the apron 3 may be varied according to the degree of drag necessary to give the fiber according to the length of staple and bulk under operation. The holders 1 are in succession )ut into position in a slide 1 say from the left hand side of the machine and removed from opposite end when the requisite beating and cleansing has been efiected. I do not limit the invention to the number of bars to three moving bars and two stationary bars as the number of either the fixed or the moving bars may be varied according to the nature and condition of the fiber to be operated upon.

Having now described my invention what I claim as new and desire to secure by Letters Patent is 1. In a scutohing-machine, the combination, with stationary crossbars arranged one above another, and an apron of flexible Inaterial depending from the upper crossbar; of a support for the fibers arranged above the said crossbars, a frame provided with curved bridges for supporting the said crossbars, arms pivoted in the said frame and provided with crossbars which work between the said stationary crossbars and bridges, and means for oscillating the said arms to transfer the said apron and the fibers from one side to the v other of the said stationary crossbars and to drag the fibers longitudinally over the surfaces of the said apron.

2. In a scutching-machine, the combination, with stationary crossbars arranged one above another, and an apron of flexible material depending from the upper crossbar; of means for suspending the fibers over the said crossbars, movable crossbars arranged intermediate of the said stationary crossbars, and means for oscillating the said movable crossbars to transfer the said apron and the fibers from one side to the other of the said stationary crossbars and to drag the fibers longitudinally over the surfaces of the said apron.

In testimony whereof I affiX my signature, in presence of two witnesses.

I/VILLIAM BENJAMIN GRAY.
