Detailed Description of the Invention
A manual weaving machine according to a preferred embodiment is herein described and illustrated in the accompanying drawings wherein;
Fig 1. schematic view of manual making machine
Fig.2. schematic view of the reverse side of the manual mat making machine
Fig. 3 shows the elevation of the dressing means.
Referring to the drawings, particularly Fig.l, a manual weaving machine has a pair of Pulling Rollers 1 & 2 mounted on the Bracket 3, secured on eitiier sides of the frame 4. Pressing springs 5 are provided on both sides of the rollers 1 & 2 to apply required pressure on the rollers 1 & 2. There is a groove 6 in either side of the bracket 3 so that the Roller 1 can slide up and down as per the required gap for passing the leaf mat. A driven shaft 9 through a beh 10, crankshaft 9 having a sprocket 9A is driven by a sprocket 11 is mounted on another crankshaft 13 adapted to be rotated by left pedal 14. The main fiinction of the pulling rollers 1 & 2 is to pull the mat ahead. A set of leaves holders 15 are secured with a rod 16. The rod 16 having guide pins 17 on either sides thereof is provided on the frame 4. Similarly, another set of leaves holders 15 are secured witii another rod 18 is provided on the frame 4, for holding the leaves during the . operation of the machine. A plurality of dressing needle 19 is provided at the front end of the frame 4 so as to keep the leaves in position separately.
Rods 16 & 18 are connected to separate linkage means provided between the crankshafts 9 & 13 respectively. The linkage mechanism has big link 20 secured rotatably with a small link 21 that is secured fixedly with the cranks 9 & 13 respectively. The lower end of the big link 20 is secured with the lower end of the small link 21 by means of a connecdng rod 22. A rack and pinion mechanism is provided on the other side of the frame 4 of the machine for inserting cross leaves

there through the big leaves. The rack and pinion mechanism has a rack 23 adapted to be moved by a pinion 24. Pinion 24 is driven by means of a driven pulley 25 adapted to be driven by a driving pulley 26. A small pulley 27 that is driven by a small pulley • 27, which is driven by a pulley 28, drives the driving pulley 26. Pulley 28 is driven by a pedal 29 secures at one end of a connecting rod 30 on which pulley 29 is mounted. A Leaf adjusting wheel 31 secured at one end of the shaft 32 of the roller 33 is provided to adjust the leaves and hold the same for weaving purposes. A leaf box 36 is mounted on the rack 23 for holding the leaves for use in cross weaving.
The Dressing means as shown in Fig.3 comprises a control lever 34 secured with a controlling shaft secured with the needle shaft 35 having controlling rope 35A secured with the needle arm 35B. A spring loaded shaft correcting rod 35C is provided to guide the movement of the arm 35B.
When the left pedal 14 is pressed one set of Leaf folder 15 goes up and simultaneously other set of the leaf folder 15 goes down, up and down movement occurs due to movement in the linkage mechanism 20, 21, & 22.. Now the right pedal 29 is pressed again and again to facilitate the forward movement of the rack 23 along with the leaf box 36 in cross direction. The Leaf is then taken out and adjusted in the gap with the help of the controlling means and the right pedal is released. The rack 23 is then withdrawn and the left pedal is pressed again for the next operation. The operation is ' repeated to weave the mat
As shown in figure 2, the weaving machine is of the same construction. The only difference is that in this machine, two mats can be woven simultaneously. And for this purpose another set of Pulling rollers 37 & 38 is provided at the extended upper end of the brackets 3. Also an additional Leaf box 39 is provided with the same rack and pinion mechanism to provide the leaf for cross weaving. All other means as mentioned herein with respect to figure 1 are for the operation of said set of rollers 37 and 38.
