JOSEPH BERGER, JR., OF UTICA, NEW YORK, ASSIGNOR TO UNION SPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
THROAT-PLATE FOR SEW ING-MAOHINES.
Application filed July 20, 1915.
To all whom it may concern:
Be it known that I, JosEPH BERGER, Jr., a citizen of the United States, residing at Utica, in the county of Oneida, State of New York, have invented certain new and useful Improvements in Throat-Plates for Sewing- Machines, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.
The invention relates to new and useful improvements in throat plates for sewing machines, and more particularly to a throat plate for a sewing machine having two sets of stitch forming mechanisms, one of which is substantially in rear of the other.
An object of the invention is to provide a throat plate with two stitch tongues, one of which is in rear of the other, the rear stitch tongue being narrower than the stitch tongue in front thereof, so that a cross stitching mechanism cooperating with the rear stitch tongue will tie down the cross threads of a cross stitching mechanism cooperating with the front stitch tongue.
A further object of the invention is to provide a throat plate of the above character, wherein the rear stitch tongue is formed integral with the front stitch tongue, so that the cross threads of the front stitching mechanism will slide off the rear end of the rear stitch tongue.
A still further object of the invention is to provide a throat plate which cooperates with a feed dog, wherein one of the elements is formed with a stitch tongue adapted to cooperate with widely spaced needles, and.
one of the elements is also provided with a relatively narrow stitch tongue located in rear of the front stitch tongue and adapted to cooperate with relatively closely spaced needles.
These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.
In the drawings which show by way of illustration one embodiment of the invention Figure 1 is a plan view of the forward end of a cylindrical work support having my improved throat plate applied thereto;

Fig. 11 is a plan view of a throat plate showing a still further modified form of the invention.
In Fig. 1 of the drawings, I have shown the end of a cylindrical work support 1, on which is mounted a throat plate 2, having my invention embodied therein. Said throat plate is secured to the work support by suitable screws 33. The throat plate is provided with feed slots 4, into which extends the feed dog 5. Said throat plate is also provided with an opening 6, into which extend the stitch tongues 7 and 8. The stitch tongue 7 is supported by the throat plate and projects rearwardly into the opening 6. Said stitch tongue is substantially the width of the opening leaving only slots of sufficient space at each side of the tongue for the cross threads to slide along the stitch tongue. The forward needles enter the enlarged openings 9-9 at the front ends of the slots along the sides of the stitch tongue 7. The rear stitch tongue 8, which is formed integral with the stitch tongue 7,
as shown in Figs. 1, 3, 4, 5 and 7 is a relatively narrower stitch tongue, having its side walls parallel. The under-facesot the stitch tongues are tapered as at 10 and 11, respectively, the tapered surfaces merging for a .purpose which will hereinafter appear.
Cooperating with the throat plate is a presser foot 12, which is provided with a slot 13, through which the' needles l4- and 15 enter, see Fig. 2. These needles'pass through theopenin s 9'9 alongside of :the stitch tongue 7. S rid presser foot is also provided with an opening 16 throughwh-ich the needles 17 and 18 pass. These needles are adaptedfto pass a'longsideot the stitch tongue '8 adjacent the end of the stitch tongue 7. Cooperating with the needles 14 and 15, beneath the work support, is a looper 19, While cooperating with the needles 17 and 18, beneath the work support, is a lo'oper 20. Inasmuch as there is a single loop'er cooperating with each pair o'f needles, there \villbe a cross thread formed joining each set of needle loops beneath the material and these cross threads are respectively laid across the stitch tongues 7 and8. Inasmuch as the needles 1'17 and 18 are spaced closer together than the needles 14 and 15 and are located directly "in rear of the same, the needleloops and the cross threads of the rear set of needles will tie down or overlie the cross threads joining the needle loops of the needles 14 and 15. The cross fthreads connected with" the needle loops of the needles 14 and 15 slide off from the end of the stitch tongue 7 on to 'the stitch tongue 8 and then off from the stitch tongue"8, the merging of the tapered undersurtaces '10 and" of these tongues assisting in this action. The longitudinal center line of the 'sti tch'tongue 8 coincides with the longitudinal center line of the stitch tongue 7, as shown in the drawings.
In Figs. 5 and 6 of the drawings, I have shown a modified form of the invention. In this form of the invention, the stitch tongues are carried by the feed dog instead of by the throat plate. The throat plate 2 has the stitch tongue out out of the same-forming an enlarged opening 21. Theteed dog has a portion of its feed teeth cut away and a plate is secured to the feed dog by a screw 23. Said plate has a groove in its underfaceadapted to engage the rib 24 on the feed dog, whereby a single screw holds the plate firmly upon the feed dog. Said plate 22 at its :forward end is provided with spaced parallel slots 25 and 26, forming a stitchtongue 7*. These slots at their rear ends respectively receive the needles 14 and 15. The stitch tongue 7 is similar in construction to the stitch tongue ,7, above 'described, except it is carried on the plate 22 mounted on'th'e feed dog instead of being carried by the throat plate. The same is true of the stitch tongue 8". It will be noted that the stitch tongues 7 and 8 move back and 'forth with the feed. These stitch tongues, however, operate precisely in the tongue 7 is precisely the same in construction as the stitch tongue described in con- .nection with Figs. 1 to 3. The stitch tongue 8 is wider than the stitch tongue 8, but
of less width than the tongue 7, and recesses 27 and 28 are provided at the juncture of said tongues for the needles 17 and 18, respectiv'ely. In this form of the stitch tonguefthe stitches formed by the thread from needles '17 and 18and the connecting looper thread are held in looser condition, so that theresulting seam is more elastic.
Fig. f the drawings, I have shown a further modified form of the invention. The throat late 2 is similar in construction to the throat plate shown in Fig. 1, except as tothe manner of supporting the stitch tongues. Instead of having one opening 6 infthe' throat plate, there are two separate openings 29 and 30. The stitch tongue 7 projeets into the opening 29 and' is spaced fron the side and end walls thereof, so as to permit the cross threads to slide 011 from the stitch tongue. The stitch tongue 8 is carried by the'throat plate and projects into the opening 30 m is spaced frointhe side and end Walls thereof. This s'titch. tongue is of considerably less width than the stitch tongue 7 and the needles cooperating with these stitch tongues 7 and 8 are spaced, as shown in Fig. 2. Each stitch tongue is separatelyisupported -and one is inrear of the other, .so that the cross threads laid across the ffirs'tstitch tongue may be released on to the material being stitched before said cross threads are stitched down by the rear pair of needles.
From the above, it will. be noted that the throat plate is termed with a cross bar which separates the needle openings and this cross bar supports the stitch tongue 8. The cross bar not onlysupports the stitch tongue but insures that the looper thread connecting the needles cooperating with the first stitch tongue shall be brought up on to the throat plate and. pass over the tongue 8.
In Figs; 9 and 10,1 have shown a further modified form of the invention. In this form of theinvention, the stitch tongue 8 is carried by the feed dog. Theii'eed dog is indicated'at 5. The plate 31' is secured to this feed dog and carries this stitch tongue 8 Said plate is formed with slots 32 and 33 for the needles-l4 and 15, respectively, and the stitch tongue is located between these slots. In this form of the invention, the stitch tongue 8 is similar to that described in connection with Fig. 8. The plate 81 is secured to the feed dog 5 in the manner shown in Fig. 6.
In Fig. 11, I have shown a still further modified form of the invention. The throat plate 2 is formed with two openings 29 and 30 and the stitch tongues '7 and 8 are located in these respective openings. The stitch tongue 7 is supported at the side of the opening and extends laterally and then rearwardly between the needles 14 and 15. The stitch tongue 8 is supported at the side of the opening 30 and extends laterall and then rearwardly between the needles 1 and 18. The rear stitch tongue is narrower than the forward stitch tongue and operates in the manner above described.
From the above description, it will be apparent that I have provided two stitch tongues which are adapted to cooperate with two sets of stitching mechanisms, one in rear of the other, and these stitch tongues are of such construction that the rear stitch forming mechanism operates independently of the front stitch forming mechanism to form cross threads which join the needle loops, which in turn tie down the cross threads of the front stitch forming mecha nism and the resulting seam of both stitch forming mechanisms is an elastic seam that is, the joining cross threads are laid over the stitch tongues and held thereon while the stitches are set, so that when said cross threads slide off the stitch tongues the seam will be more or less elastic. It is also apparent that the rear pair of needles 17 and 18 are disposed in rear of the front pair of needles 14 and 15, and that each needle of the rear pair of needles is disposed in plane extending between the needles of the front pair of needles.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. A throat plate for sewing machines having feed slots and two stitch tongues, one tongue being disposed in rear of the other, said rear stitch tongue being relatively narrower than the stitch tongue in front thereof, whereby the cross threads of a stitching mechanism cooperating with the forward stitch tongue will subsequently be tied down by the cross threads of a stitching mechanism cooperating with the rear stitch tongue.
2.
