CARPET NEEDLE Filed Dec. 19, 1927 i ztzzs a;

ATTORNEY Patented Aug. 26, 1934) EMIL J. SEEBER, OF CHICAGO, ILLINOIS CARPET NEEDLE Application filed December 19; 1927. Serial No. 241,160.

10 and claimed in my copending application,

Serial Number 218,531 filed in the United States Patent Ofiice on or about September 9th, 1927, and the salient object of this invention is to provide an improvement in the construction of the device described in the above named application which will cause the needle, when retracted, to move to a position above the point at which it is to be next inserted.

Another object of the invention is to arrange a device of the foregoing character in such a. manner that the operation thereof will be very simple in order that a comparative novice may operate the device and pro 25 duce a product of uniform quality.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing, showing the preferred form of construction and in which;

Fig. 1 is a side elevational view of a pre- 35 ferred form of construction for my invention in which certain parts are shown in section;

Fig. 2 is a sectional view taken on the line 22 on Fig. 1;

Fig. 3 is a sectional detail view taken substantially on the line 3-3 on Fig. 1; and

Figs. 4 to 9 inclusive are partially diagrammatic views depicting the various steps in the operation of my device.

Carpet needles of the type to which my invention relates include a needle having an eye therein and a looper adapted to cooperate with the needle in order to form loops in the rug on the side adapted to be disposed 5O upwardly. The needle and the looper are carried on structures which are mounted in juxtaposition to each other for relative reciprocatory movement. The device disclosed herein is constructed substantially similar to the device described and claimed in my above referred to copending application.

The mechanism comprises aneedle 10. which is formed substantially U-shaped and which embodiesa pointed end 11. The needle 10 has an eye 12 formed therein adjacent the pointed end 11 and in operation the weft strand is adapted to be inserted through the warp and then a looper is slid along the needle through the warp and engages the weft strand so as to retain said strand in position through the warp when the needle is retracted.

The needle 10 is secured in any desired manner, as by the rivets 13, to the needle member 1 1. The looper which is indicated by 5 in the drawing is secured as by the rivets 16 to looper member 17. As has been stated the needle is formed substantially U-shaped and the looper is adapted to be so positioned that it will be disposed in said U- shaped needle so as to be reciprocal therein. The members 14 and 17 include the co-extenslve portions 18 and 19. In the portion 18 of the needle member 14 a slot 20 is formed and a rivet 21 is mounted in the juxtaposed portion of the portion 19 of the looper member 17. In the portion 19 of the looper member 17 a slot 22 is formed and a rivet 23 is mounted in the juxtaposed portion of the portion 18 of the needle member 1st. The slots and rivets are arranged so as to permit relative reciprocation between the portions 18 and 19.

The portion 18 is extended and bent into substantially S-shaped portion 24: and the portion 19 is extended and is bent into asubstantially $-shaped formation 25; The pertions and include tangs 26 and 27. The opposite ends of the portions 18 and 19 are extended forwardly and then bent outwardly and rearwardly so as to provide portions 28 and 29 which are adapted to terminate adjacent the tangs 26 and 27. -landles 30 and 3.1 are disposed around the tangs 26 and 27 and the ce-operating portions 28 and 29. The above described construction is substantially fill similar to that of my hereinbeitore referred to eopending application.

I have found that considerable skill is required for proper manipulation of a device as above described since it is diflieult tor a novice to advance the needle an equal amount prior to ea h insertion. l have therefore provided a construction which will cause automatic advancing ot the needle. By referring to Fig. 1 it ma. be seen that the needle 10 is secured to the portion 18 of the needle mem her it and that the section of portion 18 to which said needle is attached, is offset as in is at dicated at 82 in the drawings. In the offset portion 32, adjacent the needle arrying end thereof, two outwardl extending lugs 33 and are struck. It will be by referring to l i that the lugs or humps are disposed on each side of he needle 10 and also that these humps extend toward the portion 19. The riv El and are arranged so as to permit a certain amount of lateral play between the members l t and 17. Theretore when the needle member 10 is retracted the peak oil the humps 333 and 34 engage the point 2-35 on the looper member 1'? and tend to spring said members apart. This action is utilized to cause 1 *ancen'lent of the ne *dle in the following manner.

llv referring to st to 9 inclusive the manner of operating this needle may be seen. In these views A, B, and C indicate three strands of a warp and it is to be understood that the device is not limited merely to warp strands and further the advance not l'nnited to a movement or merely one trand, but by regulating the size of the humps and B l the needle may be caused to ad *ance over any desired n unber of warp strands dependpoi. the coarseness of the warp. V ini the weft st and.

In F g. 4ithe device is illustrated in the first position, the weit V? has been directed through the 0)". l2 and it is to he inulerstood that the weft will he extended beyond the are l! a distance to provide an overhanging portion T which will serve as a retaining portion and which is adapted to be securely anclmred so as to prev nt withdrawal ot the welt stra id a liter inc! rtion. ln the lirst operation and prior to t e insertion the loopcr member ll is r ,trai'te as tar as the slots 20 and 22 and the ;l and :23 will permit, thus causing; the iueor ll) to be enteuded forwardly. l needle is thin. llli; tween the warp ands ill and ll and, t loop L is formed. The next 0 d picted in Fin wherein ins a aeration is that 10 needle in is lowed ti remain in its relative position but e leoper member 1T is run iorwardly so as i tl al a bring: the portion 36 thereof into engagemcn with the surfaces of the varp, it being uniilersood that th needle member 1% has been 11 J distance sutlicient o e0. iori'ardlv a to bring the oortion 37 thereof into engagement with the warp. that 's the portion 37 engages th wett t and and clamps it be tween said portion 3i and said warp. ll will be apparent that the looper 15 moves forwardly through the U-shaped portion of the needle and therefore is dispose l so as to retain loop L. It is to be understood ti at the looper la is preferably formed o t a resilient material such as flat spring steel. it is apparent that when the looper member 17 moves forwardly the portion 19 thereot rides along the humps 83 and l em out inasmuch as the looper and the needle will be held in juxtaposed position by the warp strands A and 13 said looper will be liexed as is indicated in llig. 5. The next step in the operation of the device 's the retracting oi the needle while reta... up the leoper in the position indicated in Fig. The needle in partially removed position is indicated in F (3 and it will be noted that the warp strandr and B are still holdii'ig the needle 10 and the looper 15 in substant' juxtaposed position. lowever. as soon a the needle is withdrawn from engagement with the warp strand 1 the resiliency ot the looper 15 will cause said looper to tend to straighten which will obviously move the needle 10 beyond the warp strand B and in the pre ent instance into a position above the space between the warp strands B and C. Thus it will be seen that the needle is advanced an amount equal to the size oi the humps 3 3 and 34: which will obviousl} be the amount that the loopcr 15 tends to straighten and therefore move the needh 10.

In Fig. 8 the ne. :t step of l mcration is depicted. It will he seen ih t l e needle it) has been inserted between the va p strands e1 ti B and C and it should he noted that the loopcr 15 is still retained betvi'eei'i he warp strands A and ll an l is hold n the loop ll.

i. In l ie 9 the next stzp is depicted. Herein it will he seen that the loopcr 15 has been retracted from the loop L and said loop is free. The next step in the peration will be substantially similar to Fig. 5 and the loopor will move into position between the warp strands ll and t and the above operations will therefore be repeated. 7

The proper manner of using the device ill to grip the handles ill) and 231 between the rs oi each hand and to allow the tium to re on the portions 38 and 39 and to rect the index ling aloi iiortions and 29. Obviously advance is iii the direction oi the needle 10 and therefore operation will be begun along the cd a ot the warp on the looper side. It is apparent that the humps 3S aad at will cause a uniform advancement pearance a lVhile I p referred o m quality.
