' In Great Britain December 10, 1948 10 Claims. (01. 112-s0) This invention has for itsobject the provision of a new or improved hand tool for making rugs, carpets and the like with a cut pile.

Rug-making hand tools hitherto used have usually comprised a piercing needle to which the wool or other yarn is supplied in continuous length, the needle being tubular and having a stop member which determines the extent to which it can penetrate the hessian or other backing material. With this known kind of hand tool theneedle is operated to pierce a succession orrow of holes in the backing material and leave therein a length of the yarn forming a continuous or connected series or row of loops, one for each hole, the size or length of each loop being determined by the position of the limiting stop on the needle. After a row or number of rows of connected loops have been inserted inthe backingmaterial in this way, the loopsrequire to be cut with a pair of scissors to produce a cut pile.

My improved hand tool comprises two main or body members which are in sliding engagement with each other and are provided with handles by which each can be reciprocated on the other, andthe first member carries a piercing needle for inserting the loops of wool into the backing material and the second carries means for hold ing a completed loop and scissors for cutting the loop, the scissors being positively opened and closed by means carried by the first member and co-operating with one blade of the scissors at appropriate points in the relative movement between the members. I

The two body members are conveniently formed from sheet metal and are of channel section, the flanges of one member having outwardly cranked lips which are slidably received in complementary guiding grooves on the flanges of the other member. V

The scissors and the loop holding means are carried by superimposed flexible arms mounted in the channel of the second body member so that they are resiliently urged towards the needle on the other member, and the projecting part of the needle which is forced through the backing material is conveniently of channel section so that it forms a guide for the scissors, and when the scissors are advanced through the backing material they pass through the hole which the needle has made and in which it lies. Then when the needle is withdrawn the spring arm pushes the needle over and the tool is moved bodily over so that when the needle is inserted again it makes a fresh hole in the backing material spaced at a predetermined distance from the I. them to be opened again.

One practical form of my improved tool is illustrated by Way of example in the accompany-'- ing drawings in which: I

I 4

In the drawings 50, H are the we co-operating,

main or body "members of'th'etool. Both are made from steel sheet and are of ehenhei section with their open faces abutting. The nazigeslbr the member II are formed with" oiitwafrdly cranked lips l2 which areislidably received in complementary guiding grooves l3 on thin'eni ber in formed by folding the edges'of the'fl ang'es of the member [0 as shown moreparticularly in Figure 3.

The two members arethus' coupled together for relative sliding movement in a longitudinal" direction. 1

Each of the members 10, H is "provided with-a loop handle l4 formed from a bent strip of metal secured at its ends to the membenthegrip part of the handle preferably beingcover'ed -with plastic for comfort.

At the lower end of the member It the'fianges of the channel. are partially cut away and-the' remainder is tapered to form a pointed -ne'edl'e i5 An eye I6 is pierced inthe needle a short distance from its point and the metal abovethe eye is pressed in as shown at I1 to form a 'lead for" the wool which is threaded through the' eye'. The wool is guided to the eye by threading it through an opening in a lug I8 projecting from a channel shaped pressing [9 which is secured to the body member by a nut 20- ona ,scrfew; .2l.. The lug 8 also forms a stop to limit the penetra's;

tion of the needle through the backing material and hence the length of the loop made in the wool, and if it is desired that this should be adjustable a longitudinal slot may be provided in the pressing M for the screw so that by slackening the nut 26 the lug is can be adjusted longitudinally relative to the needle, The nut 23 may also serve as shown to secure the lower end of the handle.

The means for securing the upper end of the handle to the member It! also secure the upper end of a blade spring 22, andthe lower end of the spring has secured to it a channel shaped pressing 23 which freely embraces the member It and the limbs of which extend over the sides of the member Ii. One limb of the pressing is cut away as shown in Figure 1' to form a substan- 'f tially rectangular lug 24 which works between a laterally extending tongue 25 cranked outwardly bers Ill and H, and if desiredthe pressing 2'! carrying the upper lug may I be longitudinally adjustable on the member The other limb of the pressing is cut away as shown in Figure'Z to form a cam 23 of which the bottom edge is at right angles to the longitudinal axis of the tool and the upper edge is inclined.

In the inside of the channel of the member It} there is fixed a hardened steel strip 23 or which the lower end is shaped to form a cam or tooth 30 projecting forwardly towards the Other'memher and adapted to engage one limb of the scissors to open the scissors as described below. .The strip 29 is secured to the member |B bya screw 3| and the strip may be formed with-several longitudinally spaced holes 32 as shown in Figure 4 to receive the screw so that the longitudinal position of the tooth 30 can be ad usted.

'l'he'member H has secured within its channel two superimposed

spring steel strips

33, 34, as shown in Figures and 6, Which'are secured to the member at their upper ends by a screw .35. Both strips are curved so that their free ends diverge from the base of the channel as'shown more particularly'in Figure 6, and one or each of the strips may be made longitudinally adjustable on the member II by providing it with a slot or with several longitudinally spaced holes for the screw 35. f The free end of the inner'strip 33 carries two or more parallel downwardly projecting pins 36, of which. only one appears in the drawings, and which are clamped between the lower end of the strip and a sheet metal clamps ing member 31 which is secured to the strip by rivets 38. The clamping member 31 has an outwardly cranked lug 39 adapted to engage the backing material and to limit the penetration of the pins and the scissors. I

The free end of the other strip 34 is shaped to form one blade 40 of the scissors, and the other.

blade 4| is pivoted to it by a rivet 42. The tail of the blade 4| is extended upwardly and is shaped to form a lug 43 which projects through a gap formed by cutting away a portion of one side wall of the member The lug 43 has an inclined edge 44 for engagement with the cam 28 on the pressing 23 to close the scissors and a pointed heel part 45 for engagement by the tooth 30 on the strip 29 to-open the scissors. The points of'the scissors are arranged to project from the lower end of the member II for substantially the same distance as the pins 33.

The two

strips

33, 34 carrying the pins and the scissors can be flexed towards the base of the member II but the extent of this movement is limited by the engagement of the strip 33 with a screw 46 which is adjustably screwed through a nut 4'! onrthe inside of the base and is locked by a nut 48 which lies outsidethe base and also serves to hold the lower end of the handle l4.

When the two body members are assembled together and are in substantial alignment'in a longitudinal direction as shown in Figures 1 and 2 the resilience of the

strips

33 and 34 holds the scissors blades within the channel of the piercing needle. The two body members can be separated or engaged with each other when desired by forcing the pressing 23 rearwardly on its spring blade 22 far enough to allow it to clear the lug 25 or the lug 26 and then sliding the one member longitudinally relative to the other.

The operation of the tool is shown in Figures 7, 8 and 9 in which the canvas or other backing materialis shown at 49 and the wool at 5B. The wool is threaded through the hole in the lug l8 and through the eye of the needle.

Holding the tool vertically, by the handles the operatormoves the member; l3 downwardly to force the needle [5 through the backing 49 until its progress is arrested by the lug [8. The needle carries the wool with it through the backing to form a loop 5|. The parts are then in the position shown in Figure 7. I I

The member H is then moved downwardly until the lug 39 engages the backing. The scissors, which are open, slide down inside the chane nel part of the needle through the hole made by the needle and straddle the wool loop adjacent to the eye of the needle, and the pins 36 straddle the previously formed loop, if any, and hold it against the backing. The parts are then approximately in the positions shown in Figure 8. In the downward movement of the member I the lug '43 on the angularly movable blade 4| of the scissors engages the inclined upper edge of the lug 28 and simply pushes the member 23 aside as shown'in Figure 8 so that the scissors .are not affected.

Next the member H1 is drawn upwardly again to withdraw the needle from the backing, andthe needle leaves behind it the formed loop with its bight straddled by the open scissor blades as shown in Figure 8.

The whole tool is then displaced laterally, to the right in the drawings, to the extent allowed by the flexing' of the spring strings 33 and 34 as limited by the screw 45.

The needle is thus displaced laterally from the first hole through a predetermined distance and when the member ID is moved downwardly again it makes a fresh hole in the backing and takes the wool with it to make another loop. In this movement of the member ||l theinclined edge 44 of the lug 43 is engaged by the bottom edge of the cam 28 which forces the lug 43 inwardly to closethe scissors and cut the loop straddled by them.

The member is then drawn upwardly to withdraw the scissors from the first hole and return the parts to the position shown in Figure 7, and as the member In is approaching the end of this movement the tooth 38 engages the point 45 on the blade 4| of the scissors and positively opens the scissors again.

The resilience of the

strips

33 and 34 moves the scissors back into engagement with the needle and as the member II is moved downwardly again the scissors pass through the hole just made by the needle while the pins 36 hold down the wool in advance of the out which has been made to ensure that the wool feeds through the needle when the needle is again withdrawn.

Positive opening and closing of the scissors allows the blades to be set in really efiective engagement with each other and ensures aclean cut of each loop of the wool. I I p The above description of the operation of the tool is necessarily somewhat complicated as the functional relationship between the various parts during the relative movement ofthe two body members has had to be explained in detail but the actual practical operation of the tool is extremely simple.

After threading the wool through the needle the operator simply holds the tool vertically over' the backing material and reciprocates the two members alternately in a vertical direction while maintaining a downward and lateral pressure on the tool.

Successive rows of cut loops can thus be made very quickly and with a minimum of effort.
