Be it known that I, CHRISTIAN PEDEnsnN, zr citizen oi the United States, residing et St. Lou is, Missouri, lieve invented a certain new and useful improvement in Thread-Laying i)evices, oi which the 'following is full, clear, :1nd exact description, such as will enable others sliilicd in the art te which it apperteins to ineke and use the saine,'reierence being lied to the accompanying drawings, forming part of this peeiiicntion, in Which- Figure 1 is n. side elevational view oi a portion oi e sewing-machine provided with a thread-laying mechanism constructedv in- 2tecordence wit li my invention. 'FragmenteryY top plan viewl of the thread# laying meclmnisni. Fig. 3 is o plan View oi the eein-gr n ve and. illustrated in diagram. Fig. Ili is :i cross sectional view on the line 4 i of Fig. 2. Figs. 5 and. 6 are dia-grammatical views showing the relative positions of the loop-forming elements et their extreme position. Fig. 7 e detailed perspective vievr showing the relative positions of the loopforming elements et the starting position of the needle, and Fig. 8 is e similar view showing the relative positions of the two elements :titer the stitch has been formed.

yThis invention relai es to machines for sewing` leather; and one of the object-s is to provide e sewing-machine having ay novel forni of thresid-leying mechanism whereby the stitch may he conveniently and expeditiously inede during the operation of the machine.

@ther objects end advantages, es weli as the novel det-cils oi construction, wili be speciiirelly set forth in the following description,

it being understood that changesl in forni, proportion, end niinor details of construction may he resorted to without departing 'from the' spirit of this invention or sacriiicing any of the advantages the ooi.

In or ler to appreciate the novel features oi this invention, reference should oehsd to the accompanying drawings, particularly to Fig.

This lever 6 constricted at its upper end, es indicated et 8,' and the constricted 'portion oi seid lever 6 loosely ts in en elongated recess in a slide 9, guided at its upper extremity in a slot in the bracket 1 1. The loop-forming` element which. is connected to slide 9 consists of in approximately horizontal bar slidohly secured in a guidewey i2, the forward end of said her he ing curved end provided. with an A eye or thread-opening 13. 'lhe rear end oi said har is provided with e. laterally-projecting een tion 14, connected to a rearwardly-exposed extension 15, which is secured to the slide .Ci by suitable fastening device. The looper element has what might properly be termed an oscillatory rnovcinentw-tliet is to say, it lnot only moves in a rcciprocetory manner, but also has e si'dewise or lateral rnovenient in o'horizental piene, will he apparent the construction :nid operation of the invention are betterundorstood. ,intermediate the ends of the looper is an eiongared slotJ 16, in which is edjustalil y secured 'n extension 17 on the side oi the '-fioratii'ig levcr1S,wliicli es, siststhe lever 6 in imparting the osellletory movement to seid looper.
