FIG.2

NEEDLE TABLE FOR PADDING OF PATTERN FABRICS BACKGROUND OF THE INVENTION The padding of pattern fabric or laminating of fabric and padding has been carried out heretofore utilizing a stationary upper horizontal plate or supporting surface that is provided with suitable openings and upon which are placed the padding and fabric. A second horizontal plate or supporting surface is arranged beneath the upper plate and in spaced parallel relation therewith. The second plate or supporting surface is usually provided with a cradle made up of acoil spring that is designed to receive a plurality of needles.

The upper plate or supporting surface is customarily formed with a plurality of slots which are adapted to permit the needles mounted on the second plate to pass therethrough upon the raising or moving of the second plate towards the upper plate. The use of slots in the upper plate or supporting surface results in certain short comings being created in an application of this type. The use of slots in the upper plate definitely limits the number of openings that may be provided within a prescribed area due to the shape or configuration of the slot thus resulting in the use of fewer needles than might be desirable or necessary. In addition, the configuration of the slot results in the needle being guided SUMMARY OF THE INVENTION The present invention is directed to the concept of improving a needle table for the padding of pattern fabrics wherein a greater number of needles may be employed making it possible to achieve all of the desired designs on the fabric to be treated.

An object of the present invention is to provide plate or supporting surface with suitable openings or aperatures which will act as guides for the needles and thereby overcome the risk or tendency of the needles to twist or bend when entering the padding and fabric.

Another object is to provide a needle table having a reciprocating second plate or supporting surface that is free and devoid of any means for holding or attaching the needles thereto. Such an arrangement greatly facilitates the placing or remov ing of the needles dependent upon the pattern that it is desired to achieve in the fabric.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of the stationary upper plate or supporting surface of a needle table embodying the present invention; and

FIG. 2 is a vertical sectional view, partly in section, of a needle table embodying the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT There is shown in the drawing a stationary upper plate or supporting surface 1 having a plurality of holes or openings 11 which are formed in the entire area of said plate. The plate or supporting surface I is positioned upon suitable frame members I2 which constitute a support for the plates of the needle table. The holes or openings 11 formed in the plate I may be of the order of 2,500 per square meter which readily permits the achieving of all desired designs on the fabric and padding, not shown, which are positioned upon said plate or supporting surface. The plate or supporting surface I has positioned there beneath in spaced parallel relation thereto a lower plate or supporting surface 2 that is disposed in suitable guideways in the frame member 12, not shown, to facilitate its movement toward and away from upper plate 1. The lower plate 2 is adapted to receive and support a plurality of needles 3 which are introduced through the holes or openings 11 in the plate I. The needles 3 are free of any clamps or holdings means on the plate 2 and through their own weight are supported upon the plate 2 as they are dropped through the openings 11 in the plate 1. The holes or openings 11 in the plate 1 as distinguished from the slots of the prior art structures, provide a guiding means for the needles in not only the loading of the needle table but in the reciprocatory movement of theneedles into and out of the padding and fabric.

The frame members 12 are adapted to support be neath the plate 2 and by suitable bearing means 13 a horizontally disposed rod 4 which has threaded end portions 6 and 6. The threads 6 are designed to run in one direction while the threads 6 run in the opposite direction. A crank 5 is'mounted on one end of the' rod 4. The threaded portion 6 of the rod 4 is provided with a complimentary nut 7 while a similar type of nut 7 is threaded on the portion 6' of the rod 4. The nuts 7 and 7' each have connected thereto by means of a pivotal type connection one end of a lever or arm 8 and 8' respectively. The free ends of the levers or arms 8 and 8' have secured thereto in a plane normal to the longitudinal axis of said levers or arms a

second leveror arm

14 and 14 respectively. The ends of the

arms

8 and 14 as well as the ends of the

arms

8 and 14 are secured to one another by suitable bolts or pins 9 and 9' respectively so that said arms are maintained in the rigid right angle relationship to one another at all times. The free ends of the levers or

arms

14 and 14 are provided with rollers 10 and II), respectively, which are adapted to engage the lower surface of the plate 2.

In the use of the needle table of the present invention the needles 3 are dropped through the holes 11 so that an end of each needle rests upon the upper surface of the lower plate 2. The design or pattern that is to be employed is determined by thearrangement of the needles in the holes 11 in plate 1. After the needles are positioned in the holes 11 the padding and fabric are then placed on the table I after which the crank 5 is rotated causing the

nuts

7 and 7 to move in the direction of the arrows of FIG. 2. The movement of the

nuts

7 and 7 causes the arms 8-14 and 8'44 and in turn the plate 2 to move in the direction of the arrows in FIG. 2. The

' movement of the plate 2 towards the plate 1 causes the .the plate 2 will be lowered from the plate 1 through its own weight. The needles 3 may then be manually removed through the holes 11 and rearranged by simply dropping them through the holes 11 onto the plate 2 dependent upon the pattern or design to be followed.

Although the foregoing description is necessarily of formed with a plurality of holes, said upper plate' adapted to receive the fabric thereon, a lower plate carried by said frame and arranged in spaced parallel relation to said upper plate, a plurality of needles inserted into the holes in said upper plate and having an end thereof freely engaging said lower plate and means on gaging said lower plate raising same towards said upper plate to move said needles through said holes and into engagement with the fabric on said upper plate.

2. A needle table for padding fabric as set forth in claim 1 wherein said holes in the upper plate constitute guides for said needles whereby said needles will not bend or twist upon engaging the fabric.

3. A needle table for padding fabrics as set forth in claim 1 wherein said means includes an elongated rod having threaded end portions with threads on one end portion running in one direction and the threads on the other end portion running in the opposite direction, a nut threaded on each end portion of said rod and a pair of bell cranks carried by said frame member and having an end of each bell crank connected to one of said nuts with a roller on the other end of each bell crank for engagement with said lowersplate.

Claims

1. A needle table for padding fabrics comprising a frame member with a stationary horizontally disposed upper plate positioned thereon, said upper plate being formed with a plurality of holes, said upper plate adapted to receive the fabric thereon, a lower plate carried by said frame and arranged in spaced parallel relation to said upper plate, a plurality of needles inserted into the holes in said upper plate and having an end thereof freely engaging said lower plate and means engaging said lower plate raising same towards said upper plate to move said needles through said holes and into engagement with the fabric on said upper plate.

3. A needle table for padding fabrics as set forth in claim 1 wherein said means includes an elongated rod having threaded end portions with threads on one end portion running in one direction and the threads on the other end portion running in the opposite direction, a nut threaded on each end portion of said rod and a pair of bell cranks carried by said frame member and having an end of each bell crank connected to one of said nuts with a roller on the other end of each bell crank for engagement with said lower plate.
