T ml] wlumt it may concern:
Be it known that 1, WILLIAM G. HARTLEY,
a resident of Aniesbury, in the county of Essex and State of Massachusetts, have invented 5 certain new and useful improvements in Mechanism for Cutting Loops of Pile Fabric; and
1 do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying draw ings, and to the numerals of reference marked thereon, which form a part of this specification.
This invention relates to improvements in means for cutting the loops formed by the pile-threads in pile fabric, the principal object of the invention being to construct a continuous guide whereby the loops when formed over the pile-wire will be retained and guided by a guide-bar continuously from the end of said pile-wires to the cutters.
A further-object of the invention is to support each pile-cutter in a case or shoe, which shoe is of a form designed to draw the top of the loops tightly across its face as they advance on the woven fabric. As this fabric is drawn forward the loops in this tightly-drawn condition are presented to the sharp edge of the cutter, which cutter readily severs them, and the severed threads pass by on either side 0 .of the shoe, forming what is known as a velvet or "plush surface on the fabric.
The invention consists of other novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the appended claims.
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corre- 4 spending parts in all the views.
Figure 1 illustrates a rotary cutter in position to cut the loops on the woven pile fabric as saidloops are being drawn forward over the breast-beam, the view being a diagram in section,showing parts ofthe loom and the relative position of the new device to the usual parts looking in the direction of one end of the loom. Fig. 2 is an enlarged plan view showing a number of the rotary cutters mounted on an arbor and in position to sever the 5 pile-threads as they are guided to them. Fig.
3 is a side elevation representing the rotary cutter as it revolves within the shoe, also showing means for adjusting said cutter vertically. Fig, A represents the end of thepile-wire and the guide-bar for receiving and guiding the loops to the cutter, the cutter in this view being represented as a stationary knife. Fig.
5 is a perspective view representing in detail the shoe or case in which the cutter sets and also the extension which connects it with the end of the pile-wire. Fig. 6 is a perspective View showing the loop-forming end of the pilewire, showing it as being recessed on its under side to receive the end of the extension on 5 the cutter-shoe.
Referring to the drawings, 1 in Fig. 1 is the usual yarn-beam that carries the warpthreads from which the ground fabric 2 is woven. On this ground fabric are formed 7 the pile-loops 3', which when out produce the velvet or plush effect such as form the face of carpeting or other pile fabric.
At 3 3 are the heddlcs or harnesses that control' the ground warp-threads, and 4- is the heddie that controls the vertically-reciprocating. movement of the pile-threads 5, these latter threads being led from the spool 6 on the rear of the loom.
At 7 is the pile-wire, one end, 7, of which lies on the woven fabric 2, such end being drawn down to the size of the loops desired to be formed over it, These loops are formed over the pile-wires at each pick of the looni and beat up in place by the reciprocating"lay 5 26, and by a sequence of motions they are repeateolly made and drawn forward off of said wires over the guides, hereinafter described, to the cutters 8, where they are severed, the fabric continuing forward over the breast 9 beam 25} to. the take-up roll below. (Not shown.)
Any number of flattened wires 7 and corresponding pile-threads!) may be used, and any number of harnesses or shuttles may be eni- 9 5 ployed, according to the style of goods dcsi red. Only enough of the loom is shown to illustrate the operation of my invention.
