CARPET-WIRE AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 774,695, dated November 8, 1904. Application filed November 6, 1903- Serial No. 180,119. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT PRICE, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Carpetires and Cutters, of which the following is a specification.

My invention relates to a new and useful improvementin carpet-wires and cutters, and has for its object to provide a device of this description in which the cutting-blade is removable from the wire and which can be made at a comparatively small cost and may be easily removed and inserted for sharpening.

WVith these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a side elevation of a' portion of my improved wire and cutter, showing a number of warp-threads looped over the wire ready for cutting; Fig. 2, a cross-section through Fig. 1; Fig. 3, an enlarged side elevation of a portion of my improved carpetwire with a cutting-blade inserted therein:-

Fig. 4, a similar view to Fig. 3 with the blade reversed; Fig. 5, a similar view to Figs. 3 and 4:, showing a modified form of cuttingblade; Fig. 6, a cross-section through the wire; Fig. 7, a side elevation of the cuttingblade as shown in Figs. 3 and 4:; Fig. 8, a side elevation of the cutting-blade as shown in Fig. 5.

In all carpets such as Wilton and velvet carpets the warp-threads are cut so as to form a nap upon the surface of the carpet. These warp-threads are out by passing a carpet-wire through the shed formed on the loom and when the lathe has brought the threads tightly around the wire then the wire is drawn through, said wire being provided with a cutter upon one end, so that it severe the threads at the top as said wire is drawn through. In all wires now used, with possibly one exception, the cutter is formed integral with the wire, and as the cutter must necessarily be sharpenedquite often it soon becomes so thin as to either break or become useless, and then the entire wire must be dispensed with. In my invention 1 provide a removable cutting-blade which may be removably secured in the wire,

so that the blade may be removed for sharpening and again inserted or may be thrown away entirely and a new blade inserted without throwing away the wire.

A represents the carpet-wire, which is made of different lengths to correspond with the width of the carpet being woven, and the outer end of this wire A is bent back upon itself a slight distance, as represented at A, and the inner face of this portion A and also the inner face of the wire opposite the portion A are grooved longitudinally, as shown in Figs. 2 and 6 and also by dotted lines in Figs. 1, 3, 4, and 5.

Bis the cutter-blade, the ends of which are formed at an angle to the sides, these ends being parallel one with the other and being sharpened to a sharp edge. The blade is adapted to be inserted in the grooves in the wire so that one sharpened edge extends beyond the end of the portion A and when drawn through the threads of the carpet will cut the same with a shearing out. If desired, the blade B may be reversed, so that the forward cutting edge forms an acute angle with the wire, as shown in Fig. I, instead of an obtuse angle, as shown in Figs. 1 and 3; but when the blade is placed in the position shown in Fig. 4 it possesses a disadvantage in cutting threads in which there is arquantity of cotton, as the cutter is apt to clog at the point where the cutter and the wire meet.

In Fig. 5 I have shown a modified form of blade, in which said blade is pointed at each end, so as to form four cutting-surfaces, two

at each end. This blade possesses the advantage of providing four surfaces for cutting, therefore not requiring the blade to be sharpened as often as the blade in which only two cutting-surfaces are provided; but this form of blade also possesses the same disadvantages as that described in connection with Fig. 4.

I am aware that carpet-wires have been made with removable cutting-blades; but my invention possesses an advantage in that any height or thickness of carpet-wire can be used and the wire so bentthat all sizes of carpetwire will receive the same size blade, as the blades may be stamped out of one strip of material with very little or no waste. Said blades can be made at a comparatively small cost, and therefore can be thrown away when used up without occasioning a great expense.

Of course I do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of my invention.

Having thus fully described my invention, What I claim as new and useful is-- 1. In a carpet-wire and cutter, a carpet- Wire, the outer end of the same being bent back upon itself for a short distance, said back portion extending parallel with the body of the wire, the inner face of the outer end of said Wire and also the inner face of the bentback portion being grooved, a cutting-blade adapted to slide in the groove and lie between the wire and the bent-back portion, the two edges of the cutting-blade which enter the grooves being parallel with one another, the exposed end of the blade being cut at an angle with the wire, and said end being sharpened, as and for the purpose specified.

2. in a device of the character described, a

carpet-wire, the outer end of which is bent back upon itself for a short distance parallel with the body of the wire, a cutting-blade, each end of which is formed at an angle with the edges, said edges being parallel with one another and each end being sharpened, said blade being removably held between the Wire and the bent-back portion so as to lie parallel with the wire, as and for the purpose specified.

In a device of the character described, a

carpet-Wire, the outer end of which is provided with a groove formed in one edge and cut longitudinally of the same, said outer end of the wire being bent back upon itself parallel so that the groove in the wire will be opposite and facing the groove in the bentback portion, a knife having parallel edges adapted to slide in the groove and be held between the wire and the bent-back portion, each end of said knife being formed at an angle with the wire, the ends being sharpened, the knife adapted to be turned end for end so that either cutting edge may be utilized, as and for the purpose specified.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

ALBERT PRICE.
