BRITISH oomrm MANUFACTURE OF RUGS,'GARPETS, OR LIKE PILE FABRICS Application filed June 3, 1929, Serial No. 368,088, and in Great Britain June 29, 1928.

formed until the unit lengths or strips of- 16 pile forming material have been threaded through the double thickness of material along the whole or part of the length of the same, by a reaching in tool, pricker, needle, pile fixer or the like operated either manu- 2o ally or mechanically and so that when the respective loops are flattened out, the ends of the pile forming material lie on the top face of the foundation material, while a small portion at the centre of each strip or length is at the back of the same or fixed therein.

The invention will be more particularly described by the aid of the accompanying drawings wherein Figure 1 is a transverse sectional elevation of one form of machine constructed according to the invention and with the parts in the set position for the insertion of the pile forming material.

Figure 2 is a front view of Fig. 1 with part of the rug removed to show more clearly the mechanism.

Figure 3 is a detail plan view showing one form of locking mechanism for the foundation fabric feed roll and automatic release therefor.

Figure 4 is a side elevation of the machine.

Figure 5 is a view corresponding to the left hand end of Fig. 1 with the front bar moved out of engagement with the rug after the insertion of a complete row of pile strips,

while Figure 6 is a corresponding view but 50 showing the pusher bar in its forward position after just pushing, said row. of pile strips clear of loop forming'mechanism.

In carrying the invention into effect according to one convenient manner as illustrated, a frame is provided comprising side members a, a supported on the base members I), b and formed with guides a a to receive be equal to, greater than, or less than the maximum width of rug or the like to be produced.

Means are provided to intermittently raise and lower the plate 0, said means convennions on the ends of the plate c. @One disc at is formed with peripheral teeth meshing with teethonv a gear wheel 7 rotatably mounted on the frame a and having a handle f rigidly attached thereto by means of which a part rotary movement can be imparted to the shaft to cause the plate ,0 to rise or fall according to the direction of the turning movement imparted thereto, but it will be understood that any suitable mechanism may be used for this purpose.

A roll of foundation material orbacking or warps, for instance, canvas 9 is carried by a spindle g rotatably mounted in the frame I) and said canvas is led over the ten;- sioning roll m rotatably mounted in the slots a in the frame a; so as to be capable of being drawn into frictional engagement b the weight m and cord 'm. with the roll a, then under the roll n to the feed roll p and over the plate a. I The top edge of the plate 0 is notched or otherwise adapted to form openings c for the passage of the strips h of pile forming material through the pleat or loop g of canvas formed by the plate a when in the raised position. The before mentioned plate guides a, a extend across the machine,-

as shown, or alternatively a rod or rods may be mounted on one or both sides of the plate 0 to limit the falling movement of the canvas when said plate is retracted, and thepleat g is held firmly at both sides to the plate a vertically movable plate 0 extending across the machine for the desired widthwhichmay along lines below the notches 0 by cross bars or the like carried by lever arms connected to a relatively fixed part of the machine. The front cross bar 5 is carried by lever arms i pivotally connected at i to the frame a and bearing on the peripheries of cam dlscs j, j, keyed to the shaft e, and normally rerelatively to "cams. j, 7', springs k being attached at each end to the respective lever arms 2', Z to maintain the same in contact with the respective cams j, 7' which are formed and timed to move the respective lever arms to actuate the cross bars 2', Z in correct sequence as hereinbefore explained. One of the discs d is also geared to the roughened feed roll 1), preferably by a link 12* coupled to a lever 72 carrying a pawl p engaging ratchet teeth on the ratchet wheel p? keyed to the roll axle, so that the latter is rotated during the rising movement of the grid to let off sufiicient canvas to form the next pleat or loop.

The canvas 9 being formed and retained in a pleat g or loop on the grid, as seen in Figs, 1 and 2, the strips h of pile forming material can be readily and quickly inserted through the doubled fabric by means of a reaching in tool passed therethrough and through the notches in the plate a so that-when said strip of pile is placed in the eye, hook, or

jaws of the tool it may be drawn through, and the mid portion gripped by the double thickness of said fabric.

tool actuated by hand, or if desired means may be provided to actuate the latter mechanically.

Assuming the grid plate 0 to be raised and a row of pile forming material inserted in the pleat of canvas so formed then the shaft 6 is turned by means of the handle f in the direction to lower said grid plate. Immediately the turning movement commences the respective cams j actuate the lever arms 11 carrying the front rod 71 and moves'it away from the grid 0 for a sufificient distance to clear the added row of pile, as illustrated in Fig. 5. Simultaneously with such movement of the front gripper rod, the grid 0 begins to descend and at or near the end of its downward stroke the cams 7' permit a forward movement-of the lever arms 1 due to the tension of the springs lose that the rear pusher bar Z moves forwardly to push the last inserted row of pile under the front rod 71 and leaves a fresh length of canvas across the grid plate 0 as seen in Figure 6 ready to be formed into a' pleat 'orloop when the shaft e is turned in the reverse direction and the parts moved back to the operative pocanvas forward.

The cam disc or discs' vmay be turned by hand and the reaching in sition shown in Fig. 1 in reverse order. During the lowering movement of the gnd c the'lever p is raised and the pawl p rides idly over the pawl wheel p, but during the reverse movement said pawl engages the ratchet teeth so that motion is imparted to the roll p to feed the requisite length of The reaching in tool'for inserting the pile forming material through the slots or perforations in the loop forming mechanism may be of any suitable form such as a pricker,

needle 'or pilefixer according to the nature of the material being used and may if desired be mechanically actuated. In one form of the invention the device constitutes gripping jaws which may be opened by hand or other means after the pile fixer has passed through the foundation material to allow of the insertion of the pile forming substancei The pile fixer on its return movement carries the pile material with it and draws it through the loop in the foundation canvas.

The operative stands in front of the machine and a tray 1- is provided to hold a supply of pile forming material in'a convenient position for use, said tray usually being di vided by partitions to form separatecompartments to hold different coloured pile strips.

To ensure that no movement of the foundation canvas takes place during the comparatively heavy strain occurring at the moment of insertion of each strip means may be provided to positively prevent any such move-' ment and this is conveniently effected by a locking bolt 8 carried by a lever arm 8 and adapted to engage holes formed in the side of a locking plate or disc p keyed to the axis of the feed roll p, and spaced apart for a distance corresponding to the len h of the desired intermittent traverse 0 the canvas. Said lever is under the influence of a spring 8 on a bolt s hsecured to the frame of the machine and passing through a hole in the lever, said bolt also carrying a tubular stop 8 to limit the inward movement of the lever, the spring 5 normally tending to move it to force the bolt 8 into engagement with one of the apertures in the plate p but is moved to retract said bolt by a plunger t fixed to the grid plate a engaging the end of said lever during the upwardmovement of the plate 0, said end being inclined to the longitudinal plane of the machine to cause the requisite retracting movement. The extreme end of the lever s is also inclined transversely, and the plunger t is slidably mounted in a cylindrical casing 25 a spring being provided nor-,

mally actin to force the plunger outwardly but permitting the same to slide inwardly as it contacts with the transversely inclined end of the lever 5 during the downward movement of the grid 0 without imparting any movement to said lever.

It is to be understood that the improved machine may be operated manually or by' power, and that where specific driving gears or actuating mechanisms have been described these are only given by way of example since there are other mechanisms or groups of mechanisms which can be employed to give the same effect.
