HEIVISTITCH SEWING-MACHINE.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed DBGBIILbGl 5, 1905- seliall N I 290 370- To all whom it may concern.- I

Be it known that I, JOHN CHARLES OREILLY, a subject of the King ofGreat Britain, residing at 43 Eglinton street, Belfast, Ireland, have'invented certain new and useful Improvements in Hemstitch Sewin Machines, of which the following is a speci cation.

This invention relates to hemstitch sewing machines of the class in which a single operator can do two distinct rows of hemstitching simultaneously or hemstitch two articles simultaneously on the machine.

A feature of the machine is that the hems on both articles are folded and stitched in the same direction, viz :from right to leftinstead of one being folded from right to left and the other left to right as in other double hemstitch machines. My improvements are designed to improve the construction of such machines.

Under my invention I extend the head of an ordinary hemstitch machine and carry it forward so as to form a double or twin headed machine each head having distinct, separate, and independent needle bars, presser feet bars, lifts, springs, etc., separate take up levers, and separate take up cams with the necessary mechanism to give each its own direct positive action. With this twin machine a single operator can do two rows of hemstitching simultaneously and by attaching two of the ordinary folders two handkerchiefs or pieces of fabric can be folded and hemstitched at the one operation, both hems being turned or folded in the same direction as on the ordinary single hemstitch machines at present in general use.

In order that my said invention may be properly understood I have hereunto appended explanatory drawings, whereon,

Figure l is a side elevation of the improved machine. Fig. 2 is a bottom View showing the mechanism underneath the machine table. Fig. 3 is a view of the opposite side of the machine to that shown in Fig. 1. Fig. 4 is a plan.

the head d of the ordinary machine or be secured thereto. The head 0 is made exactly the same as the head of an ordinary hemstitch machine and has a needle bar e with needle f, a presser foot g, and all the other usual appurtenances. It will therefore be seen that in the machine there are two distinct and separate heads 0, (1, two separate needle bars 6, e two distinct presser feet, 9, g each fitted with separate full length presser bar, adjusting spring and lift, etc; There is a distinct and separate take up cam and lever for each thread.

The table of the machine is extended to correspond with the extension I), c, and is fitted at its underside with additional bearings h, i for the hook (or shuttle) and feed shafts j, 76, which are also lengthened to correspond. There are two stitch forming mechanisms or hooks or shuttles Z, Z the one, Z, being the ordinary one and the other, Z an additional one. The bevel gear for rotating the hook Z is shown at m and the similar gear for rotating the hook Z at m Besides the ordinary cloth feed-carrier 0 there is a second feed-carrier 0 and a third feed carrier 0 arranged between the other two for the purpose of guiding the material being sewed. The second and third carriers 0 0 are operated in the usual manner by rook shafts. The rock shaft 12 has an arm 29 acted on by a special lift cam p on the shaft 7:.

Arranged in conjunction with the feed carrier 0 is a presser foot (1 which is attached to a rod 1' having a milled head r by which it can be pressed up by hand against the action of the spring 1. This spring presses the foot g on the cloth and the pressure can be relieved at any time by pushing up the head 1". r 1' are guide bearings for the rod 1'. If so desired the ordinary knee lift lever r may be adapted to operate the presser foot 1.

u is a cloth guide fitted to the head 0 and acting in conjunction with the presser foot g to properlyfeed the cloth.

The cross over action of the needles is effected by two separate vibrating rods 22, o the rod 12 being adjustably connected (in the usual manner) to the extreme end of the connecting rod w and the rod 0 being adjustably connected to the rod w. The rod w is con nected by a pin and slot arrangement at 111 to the rod w, which latter is connected in the usual way with the vibrating quadrant 0c operated by the usual cam (not shown).

The needle bar and take up cam of the head 0 are operated by means of a cog wheel y on the top driving shaft 2 of the machine a. The wheel y gears with a wheel 1 on the counter shaft on which is a wheel y gearing with a wheel on the shaft 2 which, by means of the usual form of cam secured to its end operates the needle bar and take up mechanism of the head 0. Owing to the fact that the hems on both articles are folded and stitched in the same direction, that is, from right to left, the same as on the ordinary Wheeler Wilson machines, the operator does not require to be specially taught how to perform the feed and folding operations.

It will be seen that this arrangement forms an. extremely strong durable and reliable machine which can be worked at a high speed.

Having now fully described my invention what I claim and desire to secure by Letters Patent is:

1. A hemstitch sewing machine having two heads, one head being arranged in advance of the other, a cloth feed carrier for each head, a feed carrier disposed between said heads, and needle bars mounted in said heads cooperating with the feedin devices.

2. The combination with a hemstitch sewing mechanism and its head of an extension frame fitted thereto said frame having a head, a needle bar working in the head, means for operating the needle bar and needle and a cloth feed carrier for each head, and a feed carrier disposed between said heads.

3. A hemstitch sewing machine having two heads the one arranged in advance of the other, a needle bar in each head, a vibrating needle on each bar, means for operating the needle bars means for operating the vibrating needles a feed carrier intermediate said heads, and means for operating said carrier.

a. A hemstitch sewing machine having two heads the one arranged in advance of the other, a feed carrier intermediate said heads, and means for operating said carrier a needle bar in each head, a vibrating needle on each bar, a punch on each bar, needle blocks, arms connected to the needle blocks, a connecting rod for operating the arms, a quadrant for operating the connecting rod, means for operating the quadrant and means for operating the needle bars.

5. A hemstitch sewing machine having two heads the one arranged in advance of the other, a needle bar in each head, a vibrating needle on each bar, means for operating the needle bars, means for operating the needles,

shuttle mechanism for each needle, feed mechanism for each needle a feed carrier intermediate said heads, and means for operating said carrier.

6. A hemstitch sewing machine having two heads the one arranged in advance of the other and being fitted on an extension frame, a feed carrier intermediate said heads, means for operating said feed carrier a needle bar in each head, mechanisms for operating the needles in each head, lever mechanism for taking up the thread in each head, a vibrating needle on each needle bar, mechanism for operat ing the needle bars and mechanism for oper ating the vibrating needles.

7. A hemstitch sewing machine having two heads the one arranged in advance of the other, a feed carrier intermediate said heads, means for operating said feed carrier a needle bar in each head, means for operating the needle bar in the one head, means for operating the needle bar in the other head and means connecting the said two means together so that the needle bars may be operated simultaneously, a vibrating needle on each needle bar and means for operating the vibrating needles simultaneously.

8. A twin hemstitch sewing machine embodying two heads, one arranged in advance of the other whereby a single operator can hemstitch two articles simultaneously, a needle bar in each head, means for operating said needle bars simultaneously, a cloth carrier intermediate .said heads, and a presser foot arranged to act in conjunction with said intermediate carrier.

9. A twin hemstitch sewing machine embodying two heads, one arranged in advance of the other whereby a single operator can hemstitch two articles simultaneously, a needle bar in each head, means for operating said needle bars simultaneously, a cloth car rier intermediate said heads, a presser foot arranged to act in conjunction with said intermediate carrier, and a cloth guide arranged to act in conjunction with said presser feet.

In testimony whereof I affix my signature in presence of two witnesses JOHN CHARLES OREILLY.
