PILE-WRE CUTTER.

Application filed July 6,

through the loops. Due to the rapidity witlrivhich these pile wires are thrown 1n and withdrawn and the number of threads to be cut upon each withdrawalv each cutting edge is subject to a `great number ofcutting operations in a short time and therefore dulls quickly and such edges must obviously there fore be either frequently' resharpened or frequently replaced.

The use of `a cutter` which is separable from the pile wire for permitting replacei ment of the blade is attended with a number of problems amongst which is that arising from the fact that the arrangement. for securing the blade in position on the one hand must serve to hold the blade in such fixed-association with the pile wire that it will not shift therein nor will it be acci-v dentally separated therefrom and, on the other hand, lwill so secure the blade as not to render its removal difficult or time con`- suming. v 1

One of the important objects vof my invention, therefore, listhe provision of an arrangement wherebya cutting blade is so associated withl the pile wire that while it is fiXedly held in position thereon and against accidental removal, its quick and effective removal is permitted. y v

Looms of the typereferred to, are already provided with pile wiresfand iti is one ofthe vimportant objects of my` invention to so devise the cutter holder and its manner of association with a pile wire that the holdercan be formed as a separable unit for attachnient to a pile wire and can be associated with the conventional form of pile vwire without requiring a replacement of the pile wires or any substantial change of recon- 'l'rangement whereby a separable struction thereto. p

My invention generally involves an arcutters are so associated with.

first preliminarily associated withthe holder.

and then moved to itsfina-l position of asso# ciation in which position, ,it is-held against movement and one of theobjects of ymy. invention is the provision of an arrangement wherebyv the preliminary associationl ofthe. bladewith the holder vcan be` readily attained and forthis purpose, Iliave kprovided means whereby the manner of the preliminary asso-` ciation 0f` the two is definitely `predeter-r` mined and this predetermination ,I vattain by providing on the holder elementfto be so associated with Ithe blade 4that the blade cannot be given only a pivotal movement with reference to vthe holder.

My invention further provides an arrange--v ment whereby as the blad-e is 4given Such pivotal movement toward its predeterminedl filial position. not only will such Ypredetermined final position also be definitely predetermined, but the blade will be lock-ed in such predetermined final position "against movement therefrom in any direction.

My invention. generally involves the pro ductionof a simple inexpensive and efficient blade holding attachment for .a pile wire,

which on the one hand holds the blade fiX- .such other objects as ymay hereinafter ap-` pear or be pointed out, I have illustrated an embodiment of my invention in the draw'-` ings wherein: I Fig. ljis aside elevational view showing a blade in its final predetermined association with the holder; i f Fig. 2 is a similar view showing the blade removed from the holder; i `f. y 1. 3 is a view similar to Fig. 1 showing.. the blade in its preliminary position of association with the holder;

Fig.` 4 is a side 'elevational view showing the flap in ran intermediate stage and. aslit` is being moved fromthe preliminary stage of 'Figi 3 to its final stage of Fig. l;

Fig. 5 is a top planview, looking down y .upon Fig. 1; and

Fig. 6 is a cross-section taken on line (i4-.6. of Fig. EZ..A

form of a thin strip' of sheet material bent 1 ing, it will be observed'that I here employ y llt) soas to provide a chainnelled construction, which is preferably although not neces# sarily U- shaped in cross-section, the channel 11 being-defined by the walls 12 and 13 upstanding from the bottom 14. One of the walls 13 is shorter than the other wall 12, thus providing said other wall 12 with the extension 15 and extending` forwardly from this extending portion 15 is the en# larged spoon-like member 16 having its upper edge curved as shown at 17 and its lower edge inclined as shown at 18, the two meeting to form the point of the spoon 19. vThe shorterwall 13 of the channel 11 has its end edge preferably inclined as shown at 22. i

` For the purposes of predetermining the preliminary association of the blade'in the as to cause the free en holder, I provide an arrangement whereby the two can be associated pivotally and in the embodiment of the invention this comprisesv a projection extending from the lnner 'surface of the extending portion 15 of the wall 12, the projection 25 extending into the path of the blade when in thev channel 11 and into the space that forms a continuation of vthe channel `between the walls 12 and 13. and the blade 26 which I prefer to use is provided with a slot or opening 27-.which 'is arranged to be received on saidpivot projection 25 so yas to permit the blade 26 to have a pivotal movement with reference to the holder, but to prevent any other movement of the blade with reference thereto except that movement byy which the blade is associated with or removed from said projection 25, and while' in the embodiment herein disclosed, the blade 26 is shown as provided with a hole 27 to form a bearing i A for pivot pin 25, it will be understood that the blade mightr also be provided with a slot open to the bottom thereof. v

The blade initially positioned as shown in Fig. 3 of the drawing, can now be moved Jto itsfinal or operative position of associationz with the holder by swinging it clockwise'abou't the pivot 25 until the forward part of the. body of the blade seats on the bottom of the channel which is its final position of operatio-n as shown in Fig. 1 of the drawing and for holding the blade yin this position, I provide the arrangement which I will now describe.v

The spoon 16 is preferably provided with the tongue 30'formed by the cuts 31, 32 and 33 to permit the tongueto be punched up so d of the finger or vtongue 30 formed by such cuts, to project upwardly above the surface'ofthe spoon 16 for a substantial distance. The spoon is further provided at the lower end of the inclined lower edge 418 with the upwardly' `extending abutment portion 35 preferablv wedge'shaped and increasing` in height in the direction of the spoon tip 19.

The dimensions of the blade is such that as vthe blade 26 is moved `from its position of Fig. 3 to its position of final association as shown in Fig. 1, the rear end of the blade will pass over the wedge abutment 35, which movement is permitted by the fact that the blade is flexible, and upon a continuation of such movement, the end of the blade will be moved under and be received beneath the finger 30, Fig. 4 of the drawing showing the blade at the beginning of its movement into position beneath the finger 30 and inv the continued movement of the blade, a point will be reached in which the blade will be fullyv received beneath the finger 30 and inermediate the rear edge thereof as shown in iig. 1. f

The rear edge of the blade 26 is preferably curved as shown at 38 along an arc of acircle of which the pivot 25 y1s the centerv of rotation and the lower partof the rear edge of the blade is inclined as shown at 39 so that when the blade is in its linal posi.

tion of association as shown in Fig. 1 of the drawing, the portion 39 of the rear edge'ofv the blade will register with and be received in'back of the wedge abutment 35.

As has already been stated, the rear end of the blade as it passes over the wedge abutment 35 is slightly flexed and as-the blade is moved to its position of Fig. 1, the rear edge thereof will have passed by this abutment 35 and will resume its normal flat position in back of such abutment with the edge 39 in contact with and in back of the abutment 35 so that no reverse or counterclockwise movement of the blade is permit-ted. v

A forward or clockwise pivotal movement of the blade beyond its Aposition of Fig. 1 of the drawing is prevented by the engagement of the lower edge of the blade with the bottom of the channel 11. A movement upwardly out of the channel is prevented by the pivot pin 25 and a movement side wise out of the channel is prevented by the engagement with lthe blade with the side walls 11 and 12 and with the tongue 30.

To remove the blade for replacement, all that is necessary to do is to flex the vlower inclined portion 39 of the rear edge upwardly suliciently so as to permit the blade to be moved from its position of Fig. 1 in a counterclockwise direction `and over the abutment 35 until it reaches a position free of said abutment such as that shown in Fig. 3 upon which it can 'be freely removed from its pivot 25.

yThe cutting edgey 26 reference to the lowerv edge 26 of the blade and the angle of incline' and the ylength of the Cutting edge withreference to its point of-pivot 25 is such that thiscutting edge is is inclined with lUpon viewing Fig. :l of the drawing, it

will be observed that the lower edge of the blade not only seats on the bottom of the` channel 11, but also seats on the wedge abut- Jnient 35 so that, in fact, theseat for the v'illustratedits use, what I claim as new and desire to secure by Letters Patent is:
