MACHINE FOR MAKING TRIMMINGSQ SPECIFICATION forming part of Letters Patent No. 256,579, dated April 18, 1882.

Application filed September 13, 1881. (No model.) i

To all whom it may concern Be it known that I, FRIEDERICH MARTENs,

of the city, county, and State ofNew York, have invented certain new and useful I mprovements in Machines for Making Trimmings, of which the following is a specification.

This invention has reference to machines for making trimmings with cut or uncut silk; and it consists'of the combination of a fixed guidetube having interior cross-wires near its front end, longitudinal looping-rodspassing through said tube, and a rotary bobbin carrying flier upon said tube.

The invention consists, further, in the combination of a fixed guide-tube having interior cross-wires, a rotary spirally-grooved guide shaft for delivering the main gut, longitudinal looping-rods passing through said tube, a rotary flier adapted to carry bobbins, and a guide-roller adjacent to the loopingrods.

In the accompanying drawings, which represent my invention, Figure 1 represents a plan view of my improved machine for making trimmings. Fig. 2 isa side elevation of the same. Figs. 3 and 4 are respectively a detail sectional top view of the improved flier and looper and an end view of the same; and Figs. 5 and 6 show detail views of the trimming, on an enlarged scalefrespectively, with single and double loops in the act of being formed on the machine.

Similar letters of reference indicate corresponding parts. y

In the constructionof myimproved machine for making trimmings the frame of the machine is preferably made of wood, while the actuating parts are made of metal.

A represents the supporting-frame, which is provided below its top part with bearings for the driving and power-transmitting shafts, said shafts carrying the pulleys by which mo tion is transmitted by belts to the flier, the feed-pulleys, and the traversing twister.

To a transverse top rail, a, of the frame A is applied a fixed hollow tube, B, which passes the rail 01., and which is open at both ends.

- Upon the tube Bis supported, in front-of the rail (1, a flier, O, to which rotary motion is imparted by a whirl, b, secured to diametricallyextending arms 0. The whirl 1) receives its motion by a belt from a pulley on the lower transmitting-shaft of frame A.

Through the fixed tubeB passes or traverses the main gut d, of linen, cotton, silk, or other material, which forms one of the longitudinal strands of the trimming. The main gut d is supplied from a bobbin, (1, (shown in Fig. 2,) and passed over a guide-pulley, 01 at the upper part of frame A, to a spiral guidegroove at the end of a short shaft, e, in line with the axis of the tube B, said shaft being also revolved by belt-and-pnlley connection with theshaft at the lower part of frame A.

The machine confines the silk or other material-which forms the trimming between the main gut d and a second gut, f, which are twisted together in the act of manufacturingthe trimming, so that they hold the looped silk between them. The main gut or strand 6?, which passes through the tube 13, is made thicker than the second gut or strand, f, which is used for binding oi the silk, the latter being supplied from a bobbin, f, or other source. (Shown in Fig. 2 of the drawings.) From the bobbin f the second gut, f, is guided over a grooved pulley, f, at the upperpart of frame, and a guide-pulley, f, to the looping device E, which extends in front of the fixed tube B.

' At each end of the diametrieal arms 0 of- .form draft may be maintained on the silk.

'lhe silk wound upon the bobbins is passed through the eyes of the flier in the usual manner, and then wound around the main gut by the flier and formed into loops by the looping device E, to be finally bound off by the second thinner gut, f, so that the loops are properly confined between the guts or strands.

The looping device E, employed for forming the loops, consists of two fixed cross-wires, 9,

arranged near the front end of the tube B, I00

along which the main gut passes forward, and of two longitudinal rods,g, which extend from the rear end of the tube B equidistantly from the axis of the same forward and a short distance beyond the front end of the tube B, said longitudinal rods being bent at right angles at their rear ends, where they leave the tube, and secured to a fixed arm, a, of the rail a, which arm also serves as one of the supports for the short twisting-shaft c, as shown clearly in Fig.

' 3. The front ends of the longitudinal rods 9 are extended forward close to the guide-pulley f over which the gut f is conducted. The silk from the bobbin G is wound around the front ends of the loopingrods g by the rotating motion of the flier, so as to form single or double loops,which are carried forward bythe motion of the main gut, so as to leave thelooping-rods g. The moment the loops leave the looping-rods 9 they are bound ofi' by the second thinner gut, so as to form thereby the trimming. The main gut is guided centrally between the rods along the cross-wires g. The surface of the guide-pulley f of the second gut, f, presses firmly against each succeeding loop of silk, which moves slowly forward with the main gut on the polished steel rodsg and over the top part of the pulley f away from the flier. The forward end of the main gut is attached to the twisting-hook h of the traversing twister F, which is supported on two parallel wires, 2', which are tightly stretched from atransverse rod, 1'', of frameAto acrossbar, i which is attached to the wall at the farther terminus of the path ofthe machine. The frame of the twister F is guided by means of eyes upon the parallel wires i, the twister being moved forward by means of a belt, l,whieh is connected to one side of the twister-frame, passed over a pulley, ,l, of the wall, then over a pulley, P, of a shaft, 1 to which rotary motion is imparted by a crossed belt and pulley .from the drivingcrank-shaft,as shown in Figs.

1 and 2. The belt I is conducted from the pulley L to a point at the opposite side of the twister-frame, and completes thus its course from one side of the twister to the other. By the belt I the twister is traversed in forward and backward direction, as required. Simultaneously with the traversing motion imparted to the twister the twisting-hook h receives rotary motion from an endless belt, 'm, which passes over a cone-pulley, m, of the shank of the twisting-hook and over small pulleys m at one end of the twister-frame, thence over a pulley, m attached to a fixed upright arm of the frame A, thence down to a pulley on the transmitting-shaft at the lower part of the frame, and thence over the straining-pulley m, whichds acted upon by the force of a weight suspended on a cord that passes over a pulley attached to the wall.

It will be readily perceived that while one belt or cord imparts to the twister its traversing mot-ion and keeps up the proper draft or tension on the main gut for forming the trimming as fast as it is delivered from the looper, the second endless belt twists the guts uniformly and effectively by the twisting-hook. When the twister has been run out to its full extent and arrived at the opposite end of its motion a piece of trimming is finished, which is then removed in the ordinary manner and the twister traversed back to its original position close to the looper, and then the end of the next piece to he formed is attached to the twisting-hook, when the machine is again set in motion, and thus the trimming produced, piece after piece, as required. In this manner a more reliable and steadier motion of the twister is obtained at any part of its track, and consequentlya perfectly uniform trimming from the beginning to the end of the piece obtained.

The loops of the trimming made on the machine may also be cut open, which is accomplished in anyapproved manner, so that either cut or uncut trimmings may thus be obtained. When the loops are made of heavy silk or other cords a regular heavy braid is formed, which is not intended to be cut, the cutting or opening of the loops being mainly designed for the loops of lighter silk.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a fixed guide-tube having interior cross-wires near its front end, longitudinal looping-rods passing through said tube, and a rotary bobbin-carrying flier upon said tube, substantially as described.

2. The combination of a fixed guide-tube provided with interior cross-wires, a rotary spirally-grooved guide-shaft for delivering the main gut, longitudinal looping-rods passing through said tube, a rotary fiier adapted to carry bobbins, and a guide-roller adjacent to the looping-rods, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 18th day of July, 1881.

FRIEDERICH MARTENS.
