by declare that the following is it full, clear, and exact description thereof.

This invention relates to an attachment for ,sewing machines iorproducing an embossed that the resulting itljllOl 1s fiatacross 1ts underside whlle the work-1s bowed upwardly seam, or, in other words, an imitation mac casin seam. I v p 7 In imitating whe commonly knowu as it has been heretofore, the practice to form this seam by hand.. This has necessarily been an expensive and need I lessly slow process.

Objects o1": thisinvention are to provide .a sewing machine which will automatically produce an imitation moccasin seem which will fit a tape and a cord beneath the work and will stitch the tape and work together on opposite sides of the enclosed cord, which will stretch the work over the cord and will produce a ridge or iii) on the opposite side of the work, and which will automatically guide the several parts into their proper relative positions.

An embodiment of the invention is shown in the accompanying drawings in which a- Figure l is a side elevation partly in section, of the device in position showing associated parts of the sewing machine, said view corresponding to a section on the line 1-1 of Figure 3.

Figure 2 is a sectional view on the line 2-2 of Figure 1. I

Figure 3 is a. plan view of the guide plate. detached.

Figure l is a sectional view on the line; 4--4 of Figure 1.

Figure 5 is a fragmentary view of the finishedproduct with a. part broken away to illustrate the interior construction.

A guide plate 1 is secured to the 'whrk plate 2 in any suitable manner and is provided with a pair oi parallel slots 3 which the needles 4 are adapted to pass. The centrzil portion of the guide is reierehly continuous, indicated at 5 to provide a. support between '51 gerallel slots 9.. fhis guide plate has a horizontal slot 6 for guiding a tape across the 5 end over .ocssnp-sriircnmo .err'rncinunn'n.

slots 3. is furtherprovided with a -cir- *culai' aperture 77 forming a' guid'ior a cord,

such guide being located aboveiandssubst'an- Hall centrally of the slot 6; as may" be seen I from Figures 3 and 4:. is to lje noted that the supportlng portion s recessed or, in other words rovided-wlthe groove inver- 'tical elignme t' with"the aperture 7. This supportiiig portion, it will be noted, prevents the tape from'being-pres'sed downwardly be:- low the-plane of the under side of the work so seai'n.

The presser foot is upwardly curved to provide a conc'eved bottomyand is provided with slots 8 through which i'the needles 4 are and, 'witlijia central continuous portion 9, adapted to hold the work in contact with the cord, as may be seen from Figure 2. Ihe presse r foot is provided with downwardly extending flanges which draw the work tightly over the cord and forces it downwardly to provide an. upwardly bu ged central portion and downwardly pi ed side portion through which the stitching passes as may be seen from Figure 2. In other words, the presser foot is provided with a groove in the portion 9 and such groove is located in vertical alignment with the aperture 7, Further it will be noted that the fla 'ges 10 on opposite sides (iii extend downwardly below the lowermost portionpli theipart 9.

In the operatioIi- ;offthe device, a. tepell of inelastic materielisthreaded through the 1 slot 6 and is in direct contact with the upgeg A cord 12 is three 7 of the guide plate and is positioned immediately above the tape 11,

The work 13., such as leather, for instance, is positioned above the cord. Two lines of stitching 1e are formed, one upon each side the cord 12, such stitching passing through the work 13 and through the inelastlc tape 11, as may he seen from Figures 2 and 5.

it will be seen, therefore, machine has beenprovided which will bend the work downwardly over the filling cord by two parallel lines of stitching. 4

it will further be seen that when the prodnot is removed from the machine that the to form an upwardly bulged portion defined that a sewing fdinelastio tape holds the Work' in approxi- I may take/different forms and is to be limited:
