MACHINE FOR MANUFACTURING HARNESSES FOR LOOMS'.

Specification of Letters Patent No. 9,584, dated February 15, 1853.

To all whom it may concern Be it known that I, DAniUs C. BRowN, of Lowell, in the county of Middlesex and State of Massachusetts, have invented a` new and useful Machine for Knitting `Weavers ,Harnesses for Power and other Looms; and I do hereby declare that the same is described and represented in the following specification and accompanying drawings.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation in connection with the accompanyingv drawings, of which- Figure l, is an elevation of one side of the machine. Fig. 2 is a section through the line e e of Fig. 1 showing the parts at the left hand of said line. Fig. 3, is a section through the line e e of Fig. 1, showing the parts at the left of said line and to the right of the line e e. Fig. 4L, is a section through the line z2 e2 of Fig. l, showing the upper part of the end stand G2 which supports the end of the rail A5 and the stand G3 fastened to GJA which supports the end of the screw l. The lower part of the stand G2 is like the stand A. Fig. 5 is a spring used to hold the lease lines open to facilitate putting the shafts into the harness. Fig. 6, is a top view of the temple L. Fig. 7 is a top view of the needle a5.

The same letters refer to the same parts in each drawing; and where one part is obscured by another part of the machine, the saine letter may be repeated upon it.

A is a hollow bar supported by two stands A A which has the rails A2 and A5 fastened to it: the opposite ends of these rails are supported by stands the upper portion of one is represented in Fig. 4. The stands A A are connected together by the rails A4 A5. The lever B vibrates in the stand AG fastened to the floor; and is acted upon by the treadle B vibrating in the stands B7 fastened to the floor which treadle extends under the machine to a convenient position for the foot of the operator to propel the machine. The rod B2 is connected to the lever B and to the crank B3 upon the shaft Bt which turns in the boxes B5 B5 upon the stands A A. The fly wheel C is upon the opposite end of the shaft B4 which shaft has the gear C2 fastened to it that turns the gear C5 fastened to the pulley G2 both of which turn upon the rod A2. The pulley Ct carries the belt C5 which turns the pulley D (upon the shaft D) which pulley has a hub with a series of teeth upon it which fit the teeth on the collar D2 fastened to the shaft D so that when the pulley D is turned in the direction indicated by the arrow it turns the shaft and operates the machine. But if the pulley D is turned the other way the series of teeth slip by each other so as not to turn the machine backward. The pulley D is pressed against the collar D2 by the spiral spring D3. The shaft D turns in the stands D2 Dt fastened to the bar A, and has the gear D5 upon it that drives the gear E and turns the shaft E in the boxes E2 4 2 fastened to the bar A. The cam E5 upon the shaft E traverses the stud E4 in the connecting rod E5 the opposite end of the stud E2 traverses in the roller a in the stand a fastened to the upright part of the rail A5. The opposite end of the rod E5 is connected to and vibrates the lever F upon the stud a2 in the slide a5 fastened to the stand F which stand is bolted to the bar A. The grooved ways F2 F2 are fastened to the stand F and the rests at a2 in which the needles a5 and 1,5 traverse are fastened to them. The sliding frame F3 traverses in the ways F2 F2 to operate the needles a5 a5 fastened to it; it being traversed by the stud in the lever F which works in the grooves b. The sliding frame F3 is made in two parts and fastened together by the bolts o2 b2 so as to adjust it for harnesses of different widths. The gear F4 on the shaft E drives the stud wheels F5 F5 which turn on studs in the slide b3 which is fastened to the slide b2 which is fastened to the stand o5 bolted to the rail A2. The gears F5 turn the gear G and screw G which rotates in the stand G2 fastened to the rail A5 and the stand G5 fastened to the stand G2 Fig. t. The screw G traverses the nut G5 which is made in two parts held together by the screw c.A

The projection on the nut G5 is fastened between the cheeks c c upon the carriage H by the pin c2 to traverse it.

The stand H is fastened to carriage H, and the rod H2 is fastened to its lower end and extends through the bar A, and the opposite end is fastened to the stand H3 which stand is fastened to the carriage H* so as to make it traverse in connection with the carriage H. The gear l on the shaft D drives the gear circle l which revolves upon the grooved rollers c5 c5 o3 which turn on the A the drawing.

studs o4 04 04 fastened into the stand I2 which stand is bolted to the bar A. The circle I carries the arm I3 which is fastened into it to deliver the twine from the spool I4 which turns on the stud I5 fastened into the circle I. The spool I4 is forced against the spiral spring c3 by the nut d so that the spool may not deliver the twine too freely into the holes cZ, d', d', CZ, in the arm I3. The cani J on the circle I pushes back the slide d in the tube Z2 fastened into the stand I2 and vibrates the lever Z3 upon a pin in the stand Z4 from the stand I2; the lower end of the lever Z3 embraces a nut upon the rod Z3 which rod extends through the stand I2 and circle I and is connected to the slide e, to traverse it upon the eye rod J fastened to the stud J 2 which is fastened to the stand I2; after the cam J passes the slide d the spiral spring e fastened to it and to the stand I2 draws it in again and pulls back the slide e. The toothed segment J3 on the circle I turns the wheel J4 on the stud e2 fastened into the stand I2. The wheel J4 is fastened to the sprocket wheel J 3 which has the pin e3 in it which is caught in a recess in the spring e4 to stop the wheel J4 as soon as the segment J 3 ceases to act upon it. The wheel J 3 carries the chain K and drives the wheel K and turns the shaft 7L in the stand K2 fastened to the top of the stand I2. The chain K also turns the wheels K3 K3 upon the flier tubes K4 K4 which turn on the hollow studs K5 K5 fastened into the stand I2. The temples L L fastened into the studs K5 K5 one of which extends under the needle a5 and the other over the needle ce as represented in rIhe spindles e3 e5 are fastened into the projections on the tubes K4 K4 and the spools f f are upon them, and are adjusted against the spiral springs f2 f2 by the nuts f3 f3. The fliers L L2 are fastened to the tubes K4 K4 and extend out so as to deliver the twine from the spools f f onto the throats of the needles a5 a, when they are shoved forward. The twine represented by a red line iS drawn from the spool through the holes in the fliers one of which is represented f3 and through the guides g g in the stands g g which stands are fastened to the fliers, and have two rollers It it in them pressed together by the springs g2 g2 fastened to the fliers and adjusted by the screws which pass through them into the fliers. The twine after it leaves the guide g passes between the rollers 7L it and through the holes -in the ends of the fliers one of which is seen at g3. rIhe swaying bar L3 is fastened into the stand I2 and extends nearly to the stand F. The

wheel K turns the shaft 71, which has the arm 7a2 fastened to it which forms the bearings of the pinion h3 which gears into the gears h4 and h3; the gear h4 is fastened to the circle k of the stand K2 and has one more tooth in it than the wheel if which turns loose on the shaft and is connected to the hand 7a2 so as to count the work performed and show the quantity upon the index 703 which has a ri1n upon it that extends back over the gears and lits onto the circle c which holds it in its proper place. The rollers t 7L deliver the twine uniformly without disturbing the twist as every device tried except the rollers run the twist back and made the twine kink so as to disturb the operation of the machine by breaking the twine and causing delay.

A stand similar to the stand G4 is required to support the end of the rail A2.

The machine having been constructed and completed as above described, I put on the lease lines m by putting it through the slot in the stand I2 under the swaying bar L3, and the lease lines m by putting it through the slot in the stand I2 under the stud J2, both which lines are fastened to the carriages H and H4 as represented in the drawing. I then take the end of the twine from the spool m2 and put it through the hole in the stud K3 putting one thread of twine above and the other below the temple L and fasten it to the hook on the carriage H4. I then take the part next to the spool and draw it tight and belay it around the pin in the carriage I-I, for the upper back band of the harness. I then take the ends of the twine from the spool m3 and put it through the lower stud K5 putting one strand above and the other below the temple and fasten it to the carriages in the saine way I did the upper back band, which forms the lower back band. I then fill the spool I4 with twine and put the end through the holes cl, al', cl', d in the arm I3 and take itdown around the needle a and fasten it to the back band. I then fill the spool f and thread the end through the hole f3 and guide g and pass it between the rollers L, h and through the hole g3 and around the needle c3 and fasten it to the back band. I then lill the spool f and thread the flier L in the same way I threaded the flier L2 and pass the twine around the needle a3 and fasten it to the upper back band. I then iill the hand quill m4 and fasten the end of the twine to the upper back band. Everything being now ready for operation I apply my foot to the treadle B and turn the shaft B4 and gear C2 which drives C3 with the pulley C4 which drives the pulley D with the shaft D and gear D5 which drives the wheel E and shaft E with the cam E3 which traverses the rod E5 which vibrates the lever F and traverses the frame F3 with the needles t3 and a3 to knit the back bands of the harness. The shaft D turns the gear I which drives the circle I which carries the arm I3 and winds the twine from the spool I4 around the rod J and needle a and makes the loops for the lower part of the harness. The segment J 2 on the circle I turns the wheel J4 with the sprocket wheel J5 once around which carries the chain K which turns the wheels K3 K2' once around with the fliers L, L2 which fliers carry the twine from the spools f and f and wind it around the back bands and the needles a5, a6. As the machine is put in motion the fliers L, L2 carries the twine around the back bands and the needles a5, a and stop as the pin e2 is caught by the recess in the spring e2 and the arm I3 carries the twine up, and while it is passing throu -h the upper part of its orbit I pass the quill m2 over the needle a5 and down under the rod J to the left of the twine from the arm I3 (so as to pass it through the loop which is being made by the twine carried by said arm) and tie a knot by passing the quill around the twine which was delivered by the quill as it was carried down, and draw the knot down close to the top edge of the rod J to form the eye. The needles a5, a6 are then pushed out to shove the ends of the tongues n, n through the stitches when the needles are drawn back through the stitches which turn the tongues over onto the barbs, so that the first stitches are held forward by the rests a4, a4 and the first stitches slip off of the needles, while the stitches knit last are caught by the barbs under the tongues and when the needles are pushed forward again they are held by the temples L, L so that the needles slip forward through them and they take the place of the first stitches turning the tongues back and holding them, while the twine for the next stitches is carried around the needles. As the circle I turns it carries the cam J against the slide ZG forcing it back and moving the lever Zia so as to move the rod al and slide e toward the end of the rodJ to slip the eye and loop back so as to be out of the way of the next loop and eye. After the cam J passes the slide JG it is drawn back by the spring e which moves the slide e back also. In the meantime the wheel F4 on the shaft E has turned the gears F2, F 5 and Gr with the screw G which has moved nut G5 and carriages II and II4 with the back bands a proper distance, so as to place the next loop and' eye the required distance from the previous ones. And if the machine is kept in operation and the attendant carries the quill as above described and ties the knots to form the eyes the machine forms the loops and knits the upper and lower back bands to make the harness of the length required',

which is indicated by the hand k2 upon the index 7a2 when I cut the twine from the arm I3 fliers L', L2 and quill and fasten the ends around the back bands, and' spread the lease bands and put the springs (like P, Fig. 5) in to hold them open while I putl in the harness shafts and cut olf the back bands. I then remove the springs P and slip the lease bands oft1 of the hooks on the carriage H4 and pull them out of the harness and then fasten the back bands to the ends of the shafts which completes the harness. rIhe swaying bar L2 presses one-half of the loops from the eyes out of a direct line from the rod J to the needle a5 which makes them longer than the others so as to throw the back band one side of the center of the harness shaft out of the way of the staples in the shaft. The distance between the loops upon the back bands may be varied by changing one of the wheels (or gears) F 2 or G, or both of them as may be most convenient.

To make the harness wider the slide F2 is raised up and the frame F2 shoved apart, and the flier stud K5, swaying bar L2 and stud J2 may be moved also and adjusted as required. If it is desirable to reduce the width of the harness the several parts above mentioned may be moved in the opposite direction.

The stand K2 may be moved up or down to tighten or loosen the chain K when necessary.

I contemplate that a rod nearly round with a sharp corner so as to tie the eyes uniformly may be used instead of the rod J W'hat I claim as my invention and desire to secure by Letters Patent isl. The fliers L, L2 constructed with a spring nose or its equivalent, so as to yield the twine when the needles draw the stitches into the rest; and to take up the binding twine or draw it tight when the stitches slip olf of the needles.

2. The apparatus or its equivalent for shoving the eyes off of the rod J consisting of the cam J, slide CZG, lever cl2, rod d5, and slide e.

3. The revolving spring nose flier L or its equivalent, in combination with the needle a5 or its equivalent for the purposes set forth substantially as described.

In testimony whereof I have hereunto signed my name before two subscribing witnesses.
