CHENILLE=SPOTTING MACHINE.

SPECIFCATION forming part of Letters Patent No. 709,587, dated September 23, 1902;

Application filed October 24,1900. Serial No. 34,167. (No model.)

To all whom, t may concern:

Beit known that we, LOUIS ORAM TRIVETT and FRED RANDALL, subjects of the Queen of England, and residents of Nottingham, England, have invented certain new and useful Improvements in Chenille-Spotting Machines, (for which application has been made in Great Britain under No. 11,807, dated June 29,1900,) 0f which the following is a specification.

This invention relates to improvements in automatic machines for forming and attaching loops or staplesof chenille or like material to lace nets, such as veilings or other fabrics, so as to form what are termed chenille spots7 on the said nets or fabrics.

The invention will be best understood by reference to the accompanying drawings, in which- Figure l is a sectional elevation, and Fig. 2 a plan, of a machine constructed according to our invention. Figs. 3, 4L, and 5 are sectional elevations illustrating the operation of the machine. Fig. Gis a side elevation, 7, a front elevation, and Fig. 8 a plan, of one of the points or instruments for registering the net. Fig. 9 is a section taken on the line X X of Fig. 8. Fig. 10 is an elevation showing the device for controlling the chenillefeeders- Fig. ll is a sectional elevation showing a modification. Fig. l2 is a sectional view of part of the cutting-plate D', bed D, a ram, ejector, and plate R; and Fig. 13 is a plan view ofthe parts seen in Fig. l2. Figs. 3 to 1l, inclusive, are drawn to a larger scale than Figs. l and 2. Like letters indicate like parts throughout the drawings.

According to our invention the framing of 'the machine is comprised mainly of two end standards A, (see Figs. l and 2,) which are either placed on a base-plate or connected by cross-stays A', as shown. On the top of the .standards is a preferably horizontal table or plate B, over which the net or material C, (see Fig. 1,) to which the spots are attached, is carried. Near the front of the plate is a bed D for carrying the spotting-rams. The upper face of `this bed is placed lower than the plate B, asshown, and its ends are secured to the standards A.

At the backof the plate B is a pairof rollers E E',lt.he former, E, of which isjournaled in bearl ings E2, secured to the standards A, and the latter, E', in the forks E3, extending from the said bearings. At the front of the bed D is a corresponding pair of rollers` F F', the former, 55 F,of which is journalcd in bearings F2, secured to the standards A, and the latter, F', in forks F3, extending from the said bearings. The material to be spotted is placed on the roller E' and is carried therefrom under the roller 6o E, along the plate B, over the bed D of the spotting-rams, and over the roller F, from which latter itis delivered onto the roller F'. The rollers E and F, or only the latter, may

be roughened and are bothv advanced the requisite distance after each row ofspots have been affixed to the fabrics C by rack-wheel and pawl mechanism, which is not shown, but may be of any well-known form. The rollers E' F' rest on the respective rollers E and F 7o and are rotated by the latter. By advancing the whole of the rollers simultaneously, as described, no strain or tension is put on the net or material O; but it is merely extended and intermittently fed forward by the said rollers and held stationary while the spots are attached in rows thereto.

` Each spotting device is comprised mainly of a hollow ram G and an ejector G'. (See Figs. l to 5.) The former are mounted in a 8o row in preferably vertical openingsI in the bed D, while the latter, G', work in the interior of the rams G. The lower ends of the Whole of the rams G are secured in and are simultaneously actuated by a bar G2 (see Fig. l) on the 85 under side of the bed D, and the lower ends of the whole of the ejectors G' are in like manner secured in and are actuated by a second bar G8, placed on the under side of the bar G2. The bar Gzis actilated-i-thatis, raised go and lowered-by forked arms H' on the rocking shaft H, which latter is journaled in bearings secured to or formed integrally with the standards A. This shaft H is provided with an arm H3, the free end of which has an antifriction-roller engaging with a cam on the main camshaft J, from which cam the bar G2 consequently receives its motion. The main shaft J is carried in bearings J', secured to The second bar G3 is actuated by forked arms l' on the rocking shaft I, which latter is also or formed integrally with the standards A. loo

journaled in bearings in the standards A. This shaft I is provided with an arm I2, the free end of which has an antifriction-roller engaging with a cam on the main cam-shaft J.

On the top of and forming part of the bed D (see Figs; l to5) is a cutting-plate D', provided with openings D2 for the passage of the upper ends of the rams G, which may be reduced in width at this point, as in Fig. 2, and on its under face with lateral passages D3, leading into the openings D2. (See Fig. 5.) The chenille K (see Figs. l, 3, and 4) is fed through these lateral passages D3 by an arrangement, hereinafter described, over the top ofthe ram G, as shown in Fig. 3, and when the latter rises the shortI length of clienille above each ram G is cut off by the latter. The lengths of chenille cutoff are then pushed up by their respective rams G and are formed into loops or staples K and at the same time pushed into the hollow ends of the rams, as shown in Fig. 4, by a looper-bar L, (see Figs. 1 to 5,) placed immediately above the cuttingplate D'. This looper-barL is provided with a longitudinal plate or former L', which enters a recess or nick G5 (see Fig. 3) in the end of each ram G and forces the chenille therein, as shown in Fig. 4. The looper-barLis normally in the position shown in Figs. .l and 5; but immediately prior to the upward movement of the rams G to form the staples K it is moved into the position shown in Figs. 3 and 4. After the staples K' have been formed the rams G are lowered and the looper-barL is moved back into the position shown in Figs. l and 5 again, leaving the staples K in the rams G ready to be delivered onto the net or fabric. The looper-bar L is connected by links L2 (see Fig. l) to arms L3 on the shaft L4. This shaft L4 is journaled in bearings in the standards A andis provided with an arm L5, having an antifriction-rollerengaging with a cam on the main cam-shaft J. The looperbar L is prevented from rising by the plate B.

In front of the bed D is a bar M', (see Figs. l and 2,) provided with a net-registering point or instrument M oppositetto each ram- G. Each point or instrument is comprised of a point FI, (see Figs. 6, 7, 8, and 9,) mounted on a stock M2, and the lower ends of the latter are secured to the bar l is luted at M2, while the stock M2 is cut away at M4 to admit the upper end of the corresponding ram G. Immediately after the formation of the chenille staples K', as previously described, the points M rise from the position shown in Fig. 4, enter the meshes of the net, and move up to the plate N and over the rams G, as shown in Fig. 5. The plateN (see Fig. l) is secured to a bar N', connected to the standards A. It is formed with a hole N2 directly over each ram G, and the said holes are inclined to the vertical, so that they run out and form openings N2 at the lower front corner of the plate N, as shown in Fig. 4. The lower ends of the clenching-rams N4 (see Figs. l, 4, and 5) are mounted in these Each point MA holes N2 in the plate N and their upper ends in openings in a second plate N5, (see Fig. 1,) secured to the bar N'. When the points M rise and move up to the plate N, each point by its movement engages with a thread of the net, and the said threads lie across the liutes M3 of the points and in the angles M5 (see Fig. 6) between each point M and its stock M2. When the points M reach the position shown in Fig. 5, they register with and close the front opening N5 in the plate N, the flute M3 of each point forming practically a continuation of the front walls of the respective holes N2 in the plate N, while the threads of the net lying across the flutes M3 consequently lie diametrically across said holes N2. rams G now rise up to the position shown in Fig. 5, and the staples K of chenille are ejected therefrom by the ejectors G' and are delivered with certainty onto the threads of the net, owing to the fact that the said threads are registered with and held directly over the rams G by the registering-points M during this operation. The staples K', of chenille, are also at the same time delivered into the holes N2 in the bar N and are held therein by the ejectors G, while they are clenched on the net by depressing the clenching-rams N4. The several operating parts then return to their normal positions again, (in which they are shown in Fig. 1,) and the net C is then fed forward ready to receive the next row of spots.

The point-bar M' (see Fig. l) is carried on the upper ends of arms O, which are mounted on a shaft O', and the latter is carried in the free ends of arms O2, mounted on the shaft O2, which latter is journaled in bearings in the standards A. This shaft O3 is provided with an arm O4, having an antifriction-roller engaging with a cam on the cam-shaft J, from which cam the point-bar M receives its upand-down movement.

The point-bar Ml is moved to and from the plate N by a cam-lever O5, (see Figs. l and 2,) mounted loosely on the'end of the shaft H,

The

IOO

IIO

one end of the said lever being connected to A the point-bar M by alink O5, while the other end is provided with an antifriction-roller which engages with a cam O7 (see Fig. 2) on the cam-shaft J. y

The clenching-rams N4 are ,depressed by means of a bar P, (see Figs. l and 2,) which is secured to the outer ends of arms P, mounted on the shaft P2. This shaft P2 is carried in bearing-brackets P5, secured to the bar N', and is provided with an arm P4, having au antifriction -roller engaging with a cam P5 (see Fig. 2) on the cam-shaft J.v The clenching-rams N4 are each raised after being depressed by the bar P by spiral springsp, (see Fig. 1,) placed on the said rams.

In connection with the points M we employ a brush Q (see Figs. l and 2) in order to help the net C down to the roots of the points M and also hold it in this position while the spots are attached thereto. This brush Q is placed above the net C, as shown in Fig. 1, and as the points M rise the brush Q descends, meets the points, and pushes the net thereon. As the points M after rising move up to the plate N the brush Q moves in the reverse direction into the position shown in Fig. 5. This action of the brush draws the threads of the net into the angle M5 of the points previouslyreferred to and holds them in this position while the chenille -spots are attached. The brush Q is mounted on a bar Q', (see Figs. 1 and 2,) and the latteris carried on the outer ends of the arms Q2, secured to a rocking shaft Q3. This shaft Q2 is in turn mounted in the ends of arms Q1, secured to a second rocking shaft Q5, which latter is carried in bracket-bearings Q5, secured to the bar N'. The shaft Q5 is connected by an arm Q1' and link Q5 to an arm Q9 on the shaft Q10, (see Fig. 1,) and the latteris provided with an arm Q11, which is actuated by a cam on the camshaft J. The shaft Q3 is also connected by an arm Q12 and link Q13 to a cam-lever (which isnot shown) actuated by a cam on the camshaft J.

If preferred, we may only use aregistering instrument M to every two ormore spottingrams G and traverse the said instruments in order to bring them opposite to those rams which are for the time being spotting. With this arrangement the registering instruments only engage with the net at the points where the spots are attached.`

The chenille K is fed through the hereinbefore-described openings D2 in the cuttingplate D' by the following arrangement: At the back of the bed D is a plate R, (see Figs. 1, 2, 3, 4, and 10,) provided with grooves R', eachof which corresponds to and leads up to an opening D3 in the plate D. The chenille K is led from suitable spools at the back of the machine along these grooves R and is intermittently advanced the requisite distance by toothed spring-feeders R2, (see Figs. 1 to 3 and 10,) working in the said grooves. feeders R2 (see Figs. 1 and 3) are hinged or pivoted to a plate L5, connected to the looperbar L, and they are thus moved forward, taking the chenille with them, when the looperbar L is moved forward to form the chenille staples K. In order to place the spots in one row opposite the spaces in the next row, we`

only feed the chenille to half the spotting device-that is, to every alternate spotting de- Vice one row and to the remainder the next row. To obtain this result, the feeders R2 are controlled by the following arrangement: Mounted in holes in the plate R at the side of each feeder is a pin R2, (see Fig. 10,) which when raised engages with a lateral projection R4 on the corresponding feeder and raises the latter and holds it clear of the chenille K. On the under side of the plate R is a bar R5, on which the lower ends of the pins R3 rest. This bar is notched or cut away at intervals, which are so spaced as to allow, say, every alternate feeder to fall into operation.

These By moving this bar R longitudinally the oddnumbered feeders may be put into action and the even-numbered feeders held out of action, or vice versa. When the bar R5 is midway between its two eXtreme movements, the whole of the feeders `R2 are raised out of action, and it is held in this position while the said feeders make their return movement. The bar R5 is carried by brackets R5, (see Fig. 1,) and its end R1(see Fig. 2) is connected'to a cam-lever R5, which is pivoted at R9 to a bracket secured to the framing. vThis cam-lever is actuated by a cam R10, which is mounted on a pin R11, secured to the standard A, and is connected to the cam-shaft J by gearing R12, which is arranged to impart half aerevolution to the cam R10 to every complete revolution of the shaft J. The chenille is prevented from moving backward when the feeders are raised by spring-catches S, (see Fig. 1,) the lower ends of which enter the grooves R' and trap the chenille K.

If preferred, instead of employing the bar R5 for controlling the feeders R2, we may use a pattern-cylinder T, (see Fig. 11,) provided with longitudinal rows of recesses T', the recesses in each `row being placed at the requisite points on its surface. This cylinder T is placed under the plate R in such a position that its periphery holds up the pins R3, but each row of recesses allows those pins R2 which register with the recesses to fall and lower the corresponding feeders into action. The ends of the cylinder are-mounted in suitable bearings secured to the framing, .and it is advanced the requisite distance each row of spots by rack-wheel and pawl mechanism of suitable construction. With this arrangement more changes may be obtained, and the spots may be thus attached to the net, so as to produce any simple pattern and at the vsame time a border of different character.

For very coarse nets we may employ springfingers V (see Fig. 11) instead of the brush Q in order to pull the threads of the net up to the fluted side of the point and into the angle M5. These spring-fingers are attached to the bar Q/ or to a separate bar attached to the bar Q'. A

When spotting tine nets or fabrics, the registering-points M are not required and may be put out of action. The opening N3 in the plate N may in this case be permanently closed by a plate secured to the front of the `plate N or aplate N used which is onlypro- 'vided with holes N2.
