' Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed October 1, 1912. Serial No. 723,317.

To all whom it may concern:

Be it known that I, BASIL SANER, a citizen of the United States, and residing at West New York, in the county of Hudson and. State of New Jersey, have invented certain new and useful Improvements in Embro 1 daring-Machines, of which the following 1s a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates toembroideringmachines, and particularly to what are known as Swiss and German embroidering machines, and the object thereof is to improve a machine of this class by doing away with the shuttle and bobbin devices and the mechanism for operating the same, and substit-uting therefor a novel stitch forming mechanism whereby the operation of embroidering any design on a cloth or fabric may be performed with a single thread where two have heretofore been employed, and whereby an improved lock-chain stitch formed which consists of a single thread on one side of the cloth or fabric and a double thread on the opposite side of the cloth or fabric, and whereby both the construction and operation of the machine is cheapened and simplified and the operation and results produced improved; and with this and other objects in view the invention consists in an embroidering machineof the class specified constructed and operating as hereinafter described a'nd claimed.

The invention isfully disclosed in the following specification of which the accompanying drawing forms a part, in which the separate parts of my invention are designated by suitable reference characters in each of the views, and in which;- Figure l. is a transverse sectional view through an embroidcring machine of the class specified, but, showing only certain de tails of the machine as originally constructed and my improvements in connection therewith;-l ig. 2 a rear view of the construction shown in Fig. l;-Fig. 2, a so. tional detail of a part of the construction shown in Fig. 1, and showing one of the loop'crs which I employ and its support and operating arm ;--Fig. 3 a plan view of the construction shown in Fig. 2 with certain. parts omitted ;Figs. 4, 5, 6, 7 and Sdetail prospective views of the cloth plate of the machine and showing'one of the needles and One of the looping devices, and different steps in the operation of forming a stitch Fig. 9 a front view of a part of a cloth or fabric sheet and showing a line of stitches produced by a single needle and a corresponding looper; Fig. 10 a view similar to Fig. 9, but showing the reverse side of the cloth or fabric, and Fig. 11 a side view of a part of a finger bar.

In the accompanying drawing, I have shown only such parts of the original machine as are necessary to illustrate and describe the construction and operatic of my improvement, and in Figs. 1, 2 and? of the accompanying drawing, I have shown at a the shuttle bar of a machine of the class specified, or the bar in connection with which the ordinary shuttles have heretofore been mounted, and it will be understood that this bar is stationary and extends from one end of the machine to the other. I have also shown at b the presser finger bar which carries the presser fingers b and the bar I) has a slight rotary movement in opposite directions and extends the full length of the machine, and this bar with its fingers b are the same as in the original machine, and in practice, a large number of the fingers L are employed. I have also shown at c the usual needle bar, which also extends the full length of the machine, and is r0- vided with the usual needle brackets 0 aving the usual needles a, and the bar 0 has a forward and backward movement, and the needle brackets o and needles 0 correspond in number with the presser fingers I)". l have also shown at (I the borer bar which extends the full length of the machine, and has a forward and backward movement, and which is provided with the usual borers which are arranged in pairs in separate vertical planes, between the presser fingers 6 l have also shown at c and c the ordinary thread guide rods which extend the full length of the machine and over and around which the threads are passed, and it will be understood that a thread a is employed in connection with each of the needles 0, and the thread guide rods 6 and a also have a forward and backward movement, in the operation of the machine-in order to take up or regulate the slack or tension of the threads e, and it will be understood that each of the threads e is wound on a bobbin 1'10 al arm the supp rts ot these bell crawl-m are Indicated at 2". in lin! mil but it will l anthimtood that then: tall cranks town f the t ti machine and an: Mill uh? ual manner.

l also provide a cloth plate m which extends the full length of the machine and is secured to the brackets h in a vertical position corresponding with the position of the prcsscr finger Z) and between which and said fingers the cloth or fabric 171 to be operated upon or embroidered is placed or supported, and made movable in the usual manner. The plate at is provided with a plurality of apertures m which are arranged in horizontal and vertical rows and the apertures in the vertical rows are three in number. the top apertures being tor the needles the bottom apertures being for the borers 1Z Secured to the back l; ot' the cloth plate m between the upper rcws of apertures m are brackets m in which is mounted a hiugitudinal intermittently reciprocating finger bar n provided with a plurality of pull fingers 11 having lateral extensions or hook members a and which correspond in number with the loop- (Is Z' and needles 0, and operate in connec-- tion therewith as hereinafter described.

1 have also shown at 0 the main drive shaft of the machine. and in the practice of my invention, I gear in connection therewith a horizontal cam shaft 0", this construction l)('ill2: clearly shown in Fig. 3. and this shaft provided with two cams 0 and o and at one side of the cam shat't a the. frame work of the machine is provided with a bracket to which are pivoted two cam operated levers 7 and r. The cam lever is protided with an antitriction roller p In connection with whit-o the aim 0 operates, and the ram lever 2' i provided with an antifriction roller cf in connection with which the cam operates. Connected with the free end vi the (Hill lever i is a liulc 7) which is also nnected with the corre-niomling end of the loogar operating bar i and the connection of with bar 7' at p is made by means of a lateral hook-shaped extension formed on the end of saidbar, as shown at p in Fig. 3,

and whereby said bar is given a longitudimil movement, and in the operation of the machine, this bar is also given a lateral movement by the arms j which operate the loopers 7c.

The levers p and 1' are operated in one direction by the cams 0 and 0 and in the 0 posite direction by springs s and s and said springs serve to hold said levers in their outmost position, as will be readily understood.

It will be understood that the sheet m of cloth or fabric to be embroidered is supported in a frame which extends the full length of the machine, and which is operated by a ntagraph device in the usual manner, sai frame and pentagraph being not shown.

The upper ends of the presser fingers b are provided with inwardly set parts 6 and the upper edge portion of the plate m is provided with a correspondingly inwardly set longitudinal portion m between which the cloth or fabric sheet m is held and immediately below which the needles operate, and the object of this construction is to hold said sheet in proper position without interfering with the movement thereof.

The longitudinal movement of the bars and n, in the operation of the machine, is an alternate movement, or in other words, when one of said bars moves in one direction the other moves in the opposite direc-' tion, and in the operation of the machine the needles 0 are threaded in the usual manner, and the position of the cloth or fabric sheet m adjusted as desired. In the first movement of the various parts of the machine, in beginning the process of embroidering, the needles 0 and loopers 7.: are thrown into the position shown in Fig. 4, which is the position assumed at the begin-- ning of the formation of a stitch, at which time the needles are at the limit of their projection through the cloth plate 471, and. the loopers are in their lowermost pbsition caused by rocking the bell cranks f through the bar 9, and the. loopers are also slightly rotated by the cam 0 through the cam lever 7), link 71 and loo-per operating bar j. The second stepin the formation of my improved locleehain stitch is shown in Fig. in which a needle is shown slightly withdrawn leaving a wide loop 3/ in the thread c, a looper is being shown turned to its limit of rotary movement to the left, and under one-- half of the loop 7 The third step is shown in Fig. 6, in which a looper I0 is raised, a finger 1E projecting into the loop 31 and the thread resting on the shoulders k". The fourth step in the operation of forming my improved lock-chain stitch is shown in Fig. 7, in which a needle 0 is withdrawn entirely leaving the loop y resting on the shoulders and a loo or is raised and partially rotated to the right from its position shownin Fig. 6. The fifth and last step is shown in Fig. 7, in which a finger n carried in the finger bar n is holding the loop 1 down below the path of travel of a needle 0 The needle 0 is projected through the cloth plate 15?, and through the recess is in a looper k, which latter is shown entirely raised and turned to its limit of rotary movement to the right, and as the parts assume the position again, shown in -Fig. 4, the loop y is drawn forward through the aperture m over the needle and into the fabric, the result being shown in Figs. 9 and 10.

It will be understood that the borers or borer needles (Z operate in the same manner as in other machines of this class, and in their operation pass through the corresponding apertures m in the plate m.

While I have shown and described the preferred form of my improvement, it will be understood that my invention is not limited to the exact details of construction herein shown and described, and various changes therein and modifications thereof may be made, within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages,

Having fully described my invention what I claim as new and desire to secure by Letters Patent is 1. An embroidering machine provided with the usual thread needles. an apertured cloth plate through which said needles are movable, vertically movable and rotatable loopers secured adjacent to the side of said plate opposite said needles, and pulling devices mounted between said loopers and said plate and operating in connect-ion with the needles and loopers to form embroidery stitches with one thread.

2. An emlr'oidering machine provided with the usual thread needles, borer needles and presscr fingers, an apertured cloth plate in connection with which the presser fingers operate, longitudinally reciprocating bars mounted adjacent to said cloth plate and on the side thereof opposite said needles, and loop former devices connected with said bars and operating in connection with the thread needles for forming embroidery stitches with one thread.
