MACHINE FOR UNITING LOOPED FABRICS.

Application filed February 17, 1922. Serial No. 537,216.

To all wiwm it may concern:

Be it known that I, PATRICK P. LA Mon- TAGNE, a citizen of the United States, residin at Bourbonnais, in the county of Kanka es and State of Illinois, have invented certain new and useful Improvements in Machines for Uniting Looped Fabrics, of which the following is a specification. reference being had therein to the accompany- '10 ing drawing.

This invention relates primarily to machines for uniting looped fabrics, and 1t has especial reference to machines for sewing together the looped edges of such articles as hosiery.

The object of the invention 1s to provide a simple but effective device to be associated with a machine, for instance, for looping the edges of stockings, such device being designed automatically to effect a strlpping of the stockings off the machine after the looped edges of such stockings have been united.

When a hosiery article is knit upon a circular knitting machine, say, beginning at the toe, the edges at such toe have to be united and sewed together to complete the stocking. Machines of this general type and of various forms are well known in the art and usually comprise a rotatable supporting cylinder or dial carrying a circular series 0 radially-projecting which the edges of the knit or looped fabric to be united are superposed or impaled, and

which edges are then, by suitable stitchforming mechanism, constituting a component of the machine, sewed together. The articles thus to be stitched together are successively placed upon the impalmg pins by the hand of the operator; and, according to resent day practice, the completed stock ng is manually removed from the impalmg pins. It is the purpose of the present 1nvention to eflect such removal or stripping of the completed hosiery from the impaling pins automatically, whereby the operator is relieved of having manually to perform that operation and can. therefore, direct her attention almost exclusively to impaling the edges of the hosiery upon the pins and thereby speed up production to a substantial degree.

I am aware that, from time to time, it has heretofore been proposed to utilize deimpaling pins upon vices for efiecting the stripping action contemplated by my invention; but the action of such devices has usually developed serlous difliculties in that, in the event that the stocking for any reason adheres to the impalmg pins and the device fails to funct1o n to strip the same, such stocking effects a ammlng of the hosiery between adjacent parts and the pins, with the result that such impaling pins are broken or otherwise seriously damaged. It is the object, therefore, of the present invention to provide an efiiclent automatic mechanism which will be thrown out of action by the article itself and prevent injury to the impaling pins and the article in the event that such article is not removed by the device.

In order that the invention may be more readily comprehended by those skilled in the art, I have revealed a practical embodiment thereof in the accompanying drawings but these are .to be considered as merely illustrative and it is to be understood that other embodiments and other utilizations are within the spirit of my invention and that, also, the illustrated structure is susceptible of a wide range of modification and variation without departing from the salient features or underlying principles of the invention.

In these drawings:

Figure 1 is a view in top plan of a looping machine with my invention incorporated therein;

Fig. 2 is a fragmentary view in vertical section, on the line 2-2, Fig. 1; and

' Fig. 3 is a view in perspective of the hosiery-stripping device, detached.

It is deemed unessential, for the purposes of the present disclosure, to describe in detail a machine for sewing'looped fabrics of the type herein illustrated, because the construction and operation thereof are well known in the art. It suffices to say that this machine includes a base 1 which, as usual, is secured to a suitable table or bench and includes a main driving shaft 2 for operating a dial-rotating mechanism designated, generally, by the reference-character 3, and stitch-forming mechanism designated, generally, by the reference-character 4, and other operating parts of the machine. Outstanding from thebase 1 is a dial-support 5, and thereon rotates a pin-support or use Add

ring 6 provided with radially-projecting impaling pins or points 7. These pms are of sufliclent number and length to hold the meshes orloops of the edges of .a given article, such as a stocking, which are to be united after the operator has placed such articles successively upon the impaling pins at various distances apart.

A cutting mechanism, designated generally by the reference-character 8- and preferably of the type disclosed in United States Patent No. 1,205,107, granted November 14, 1916-is operatively associated with the pinsupport 6 so as to-sever the uniting thread produced by the stitch-forming mechamsm 4, whereby the operations on the stocking are completed. I

It will be understood that the pin-support 6 rotates continuously so that the stockings, placed upon the impaling pins or points by the operator, are successively presented to the stitch-forming mechanism 4 and then to the thread-severing mechanism 8 and the continued movement of the ring-support 6 carries each stocking into the operative zoneof my improved stripping mechamsm,.des1gnated enerally by the reference-character 9. This evice includes an arm or member 10 provided with a portion 11 having elongated slots 12 to receive cap-screws 13 for securing the arm 10 and bracket B which, in turn, is secured to the support 5. The arm -10 is angulated-at 1 1 to form an offset portion 15 overhanging the impaling pins 7 and occupying a position slightly above the plane of the pins, as shown in Flg. 2. By reason of the slots 12 and the screws 13, the arm may be adjusted in a horizontal plane whenever occasion requires. The outer extremity of the offset portion 15 is provided with a lug or extension 16, for a purpose presently to be explained.

Pivoted to the offset portion 15 of the arm 10 is aswinging connecting element 17 which turns on a pivot 18. The swinging element carries a sto or upstanding post 19 adapted to abut eitlier against the lug 16 or against the edge 20 of the offset portion 15. Thus, coacting means carried by the arm 10 and the element 17 operate to limit the swinging movement of the element 17 in both directions. Connected to both the arm 10 and the swinging element 17preferably on their lower faces-is a contractile spring 21, the function of which is to exert a normal pull on the element to hold the stop 19 against the edge 20 of the arm and,'thus, maintain the element 17 normally in the position shown in Fig. 1. The spring 21, however, is of such strength as to yield and permit the member 17 to swing to the position shown in dotted lines in Fig. 1 when suflicient force is exerted by swinging movement of the element 17 to overcome the tension of he spring.

aaeaeev Pivoted,,as at 22, on the swinging element 17 is a hoslery-engaging member 23 comprising, in this instance, a body-portion 24, a hosiery-stripping portion 25, and a handleportion 26. The stripping portion 25 has a curved edge 27 and a relativel straight edge 28, the latter adapted norma ly to ride against the periphery 29 of the rotatable m-carrying ring 6, as shown in Fig. 2. The hosiery-engaging member 23 carries a stop or upstanding post 30 adapted to em gage lugs or projections 31 and 32, respectively, formed on the swinging element 17 at opposite sides of the pivot '22. Thus, the swinging element 17 and the hosiery-engag- 1n lin liting the rotative movement of the hosiery-engaging member in respectv to the swinging element. The handle-portion 26 of the member'23 enables the operator to swing the member on its pivot 22 whenever it is necessary or desirable manually to displace the edge 28 from the periphery-29 of the ring-support.

Outstandin from the bracket B is an extension 33 tfirough which extends a set screw 34 and which carries a lock nut 35 for holding the set screw in any set position. The screw 34 is adapted to bear upon the upper surface of the ofl'set portion 15 of the arm 9 and to adjust the same vertically in order to position the arm and the parts which it supports in proper o crating relation with respect to the impaling pins 7.

Operation: It being remembered that the member 23 carry coacting means for function of this structure is to effect an au- 27 of the hosiery-engaging member 23, it is caused to slide along such surface by the progressive movement of the pin-carrying ring 6 until the impaled portions of the hosiery reach the point 36, say, of the member 23, whereupon the successive loops of the article are displaced from the pins and, when all the loops of that article have been thus displaced from the pins, it will drop into a suitable receptacle provided for the purpose. Thus, it will be seen that the progressive travel of each hosiery article, impaled upon the ins, brings it into engaging position with t e member 23 in order that that member may function to remove the article from the pins. If, however, the loops bind or otherwise adhere 'to the pins so that instead of the loops being displaced from the pins the stocking is carried forward thereby, and if the engaging member 23 were so constructed as to be rigid andbreaking or seriously damaging the pins essee? or other parts of the machine. The replacement of such pins is an-expensrve and tedious operation and uts the machlne out of action a considerab e eriod. However, by reason of the construction here proposed, in the event that a stocking is not readily displaced from the pins by the dev ce, the engaging member 23 Wlll be given a tendenc to swing on its pivot 22, and this Wlll cause the connecting element 17 to swing on its pivot 18 and against the tension of the spring 21. In other words, the force of the traveling article is imparted to the swinging hosiery-engaging member 23, and this force is transmitted thereby to the swinging element 17, so that it will gradually swing outwardly on its pivot 18 and, as it does thls, the member 23 will be permitted to swing on its pivot 22. its point 37 riding on the-periphery 29 of the pin ring until such point is free of the periphery. In other words, during this swinging movement of the element 17 and the member 23, they will gradually assume the position shown in dotted lines in Flg. 1. Then, the stop 19 on the member 17 will have been moved away from the edge 20 and against the lug 16, while the stop 30 on the member 23 will be moved away from the lug 31 and into engagement with the lug 32. The dimensions of the parts are such that when the stop 19 is against the lug 16 and the stop 30 is against the lug 32, the point 37 of the member 23 will be disengaged and free to swing out of contact with the pin ring, so that the article, still hanging on the plIlS 7, will travel beyond the device, whereupon it may be removed by hand. In consequence of the yielding and swinging capacltv of the element 1 and the member 23, anger of damage to the pins or other parts by jamming is absolutely precluded. At the same time, the tension of the spring 21 is sufficient ordi narily to resist the force of engagement of the article with the member 23 So that it will not be actuated but will, itself, function gradually and progressively to remove the different loops of the united edges of the fabric from the pins and, thus, strip the article from the ring support. In actual operation, this device has been found to.

function with certainty and efficiency and in such a way as to insure the machine against damage in the event that any particular hosiery article sticks to the pins, as will occur when such pins become rusted, deformed, etc.

It is to be noted that, as an article of manufacture, the article-stripping device herein-described may comprise the arm 10, the connecting element 17, the hosiery-engaging member 23, etc.; or, in some instances, such article of manufacture may also comprise not only the arm 10, the conthat I have provided a simple but effective device for the purpose pointed out.
