To all whom at may concern:

Be it known that I, VVENDELL P. AN-

ments in Sewing-Machines, of which the following is a specification.

This invention relates to machines for sewing together the ends of pieces of cloth preparatory to passing them as one continuous strip of cloth through the various operations of dyeing, singeing and bleaching. Its

objects are to easily and quickly secure the ends of the pieces together without waste and to make the connection in such form that the continuous piece of cloth thus produced is adapted to pass through all of the machines used in the dyeing, singeing and bleaching operations. It is known in the art that for most of the operations the ends may be secured together by an ordinary seam with the loose ends together on one side of the strip, and this common in the art. This form of scam however makes a lump due to the three thicknesses of cloth at the point where the loose ends lie against the main body. The loose ends furthermore do not always lie smooth, and thus the lumpy effect is increased. This form of scam heretofore in common use will not pass through some of the machines. such as the calender rolls without injury to the rolls,

and it has therefore been customary at that stage of the operation to cut out the seam and to secure the ends together by paste, overlapping them to a considerable extent end to end. and thus having a smooth connection embodying only two thicknesses of cloth. This however results in waste of material and requires a considerable amount of work. By my invention the smooth conncction of two thicknesses is secured in the first instance. In connecting the pieces furthermore they are stretched smooth and the loose edges are trimmed ofl". Therefore no lumpy effect is produced.

The novel features of the invention will be apparent from the following description taken in connection with the accompanying drawings.

In the drawings,Figure 1 is a side elevation of a sewing machine having my invention applied'there'to; Fig. 2 is an end elevation showing the platform of the machine in section; Fig. 3 is a plan view of the cloth holding, feeding and trimming means; and Fig. 4 is a detail perspective view of one of the trimmers.

In carrying out my invention I may make use of an old form of sewing machine adapted to sew several parallel rows of stitches, preferably as many as three, and therefore in the present case it is unnecessary to describe in detail the mechanism of the sewing machine proper,and it is sufficient to describe my additions and improvements.

,In the drawing, 1 represents the platform or table of a sewing machine, and 2 represents the head of the sewing machine which carries three or more needle bars 3 adapted to operate together and produce three parallel rows of stitches. It will be understood that the cloth operated on by the-machine is moved beneath the needles by an ordinary feed dog i which is operated in the usual manner. In order to make the cloth operated on lie smooth so as to prevent creases and a lumpy effect it is necessary that the cloth be stretched and held firmly during the time that the rows of stitches are being applied to it. In Fig. 3 I have shown means.

end of the frame and are then stretched and secured to the pins 7 at the other end. This results in having the --cloth overlap end to end and holds the portion in which the rows of stitches are to be formed in a perfectly flat condition. The frame 5 move with the cloth beneath the needle bars, and it is preferably guided in this movement will of course by lugs '8 formed on the platform or table,

and if desired rollers or other antifriction means may be used beneath the frame tomake it move evenly. Since the frame is necessarily quite long it is desirable to have the platform of the machine considerably wider than is usual for sewing machines so as to furnish a proper support for the frame.

- Furthermore, since the cloth operated on is quite wide and must be brought in from both sides it'is desirable ,to have the arm. 9'

of the sewing machine longer than usual so as to permit bringing the cloth easily into position, although I have found that a machine having amarm of the ordinary length can be used satisfactorily.

to be sewed together are not always straight, and unless trimmed ofi' parallel to and near the outer row of stitches the loose ends would be likely to become folded or creased, thus creating a lumpy efiect, and therefore I have devised means for trimming the loose ends immediately adjacent the outer row of stitches. This trimming operation is performed at the same time and by the same machine that sews the ends together. It will be observed that when the two ends are over lapped, one loose end is above the body of the cloth and the other loose end is below that body, and it is necessary to trim both loose ends. My trimmin means for' the upper loose end consists of a bracket 10 secured" to the head of the machine and exten ding down to a point just above the table where it is formed into a finger 11 whichextends in the direction of the line of feed, and

which tapers to a point. This finger is im-' mediatelyoutside of the outer row of stitches and it' carries a cutting blade .12; pivoted at 13-to the upright portion'of the' bracket 10 and having a sharp edge which coiiperates with the sharp edge of the finger to form shears for cutting the cloth. A stop block 14 on the bracket 10 limits the upward movement of the blade 12 and a spring 15 tends to raise that blade. The blade is depressed to perform its cutting operation by a bent-finger 16 carried by the needle bar '3 and extending to a position where it will strike the top of the blade and depress it every time the needle descends.

' understood that when the ends of the cloth carried by the frame 5 are fed forward toward the sewing mechanism the finger 11 will be made to enter between the upper loose end of the cloth and the main body, so that it will trim the upper loose end. Similar trimming mechanism is used for cutting the lower loose end, this mechanism being shown in detail in Fig. 4. It embodies a finger 1.7 adapted to extend above the sur;

face of the table in the line of feed on the side opposite the finger 11. This finger has a shank which extends down through the platform or table and which is secured in place in any suitable manner, but which I preferably secure to a block 18. which is fastenedto the under surface of the plat form so as"to;hold the finger in. place. A blade 19 is pivoted at 20 to the upright portion of the finger and below the, horizontal The edges of the pieces of cloth which are It will be I combination with means for sewin I portion thereof. This cutting blade cooperable manner from the main operating shaft of the machine. It; will be understood that any suitable means maybe used for operating. the'blade 19. It'will further be understood that the finger 17 is placed between the lower loose end of cloth and the main body as it is fed forwardto form the stitches, and that consequently the loose end is trimmed immediately behind the stitching mechanism.

While the ordinary feed used on sewing machines-of the type illustrated would generally be sufiicient" to, feed the cloth carried "by the frame 5', I find'that it is desirable to provide additional feeding means, and particularly to provide means for moving the cloth and frame beyond the point where the v stitching is completed, so that the trimming operation'may alsobe completed. Any suit in the drawings I have illustrated a roller been sewed, andwhich'is geared toturn at the same peripheral speed as the cloth which is being operated upon. This roller is mounted on an arm 26, and may be turned on the pivot 27 up out of theway without stopping its motion, and it may thus be brought down ontothe cloth when desired. It will be understood that the roller is driven able means may be used for this purpose and 25 operated by the machine and adapted to bear on the cloth at the .point where it has the usual way by belts or chains passing over gears.

Having thus described the invention, what is claimed is l. In a device of the class described, the

combination with a sewing machine table, of a plurality of needle bars for sewing a plurality of parallel rows of stitches, cloth feedingmeans, an open feeding frame on said table freely movable in the lineof feed and provided with means to receive and hold in stretched condition the overlapped ends of cloth in such position that the overlapped port-ion will receive said rows of stitches and willbe acted upon by'isaid feeding means, i 7
