Referring to the drawings, in which like reference characters indicate like parts, 1 designates the table or bed plate of my novel machine, outlined in Figures 2 and 3 in dotted lines, upon which plate are mounted the'various operative elements of my novel machine. 2 .designates an upper arm or housing consisting of the upright portion 3, which passes through the bed plate or table 1 and is suitably secured thereto, and the overhanging horizontal, longitudinal portion 4, which is supported by said upright portion 3.
The upright housing portion 3 is provided at its lower end with a pair of pendant, longitudinally aligned bearings 5 and 6, in which is journalled the main shaft 7, extending horizontally and longitudinally of the machine, the free end of said shaft being journalled in a bearing 8, which is secured tothe lower surface of the table or bed plate 1,- by means ofsuitable bolts 9. The main shaft 7 carries at'its outer end a suitable pulley 10, which is adapted to receive any suitable belt for lthe transmission of power to said shaft 7, and a suitable hand wheel 11 whereby said shaft may be revolved manually, and which also serves as a flywheel to give a smoother action to the reciprocating parts of the machine. f.
The main shaft 7 also carries a pair of opposed bevel gears 12 and 13 respectively, which are in mesh with a common bevel gear 14, carried by the lower end of an upright transmission shaft 15, which is journalled in the suitable bearings 16 and 17 in said upright portion 3 of the housing 2; one of Said bevelled gears 12 and 13 being iixed to the shaft 7 at all times, by means of a set screw 18, while the other of said bevelled gears is loose and idles on said main shaft 7. By changing theset screw lfrom one of the bevel .gears 12 and 13 to the other, the direction of rotation of the upright shaft 15 is reversed thereby adapting the machine either for the cut end loops or tufts, or for another character of stitch formed by reverse operation.
The main shaft 7 is further provided with a series of eccentric cam discs 19, 20, 21, 22 and 23, each of a different diameter and eccentricity, and is also provided with an'eccentric head.24, carried by the endv of said shaft, and suitably fixed thereto by the screw or pin 25. The upright transmission shaft 15 isprovided with the bevel gear 26 atits upper end, which is in mesh with the bevel gear 27 carried by the end of an upperfshaft 28, which is journalled within the bearings 29 and 30 in the upper horizontal portion 4 of the housing 2. The sprocket wheel 31 is secured to the other end of said shaft 28.
The two pendant vertical parallel guideways 32 and 33 are secured to the underside of the table or plate 1, or may be formed integral therewith. Between the two guideways 32 and 33, shown more particularly in Figures l and 2, is slidably mounted a reciprocable slide block 34, which is provided with a suitable vertical opening 35 extending therethrough, which is adapted to receive the tubular needle 36, and to support the same beneath the table 1. The set screw 37 extends into said opening 35, and is adapted to fix and secure the needle 36 in any desired position; thus permitting the vertical adjustment of the needle to produce loops of the desired length.
The slide block 34 is further provided with a transverse horizontal guide slot 38 in the upper portion thereof, while the eccentric head 24, carried by the end of the main shaft 7, is provided with the inwardly enlarged T channel 39, which is adapted to receive a nut 40, carried by the threaded end of the stud 41, said stud being provided with a squared opening 42, for the reception of a square shank wrench. The stud-41 extends into the guide slot 38 in the slide block 34, as shown .particularly in Figure 3. Thus, by setting and fixing the stud 41 at any desired -point in the T channel 39, with respect to the center of rotation of the head 24, said stud 41 will impart to said 'slide block 34 a vertical reciprocating movement, of a stroke dependent upon the distance of said stud 41 from the center. By means of the adjustable eccentric stud 41, it is thus possible to adjust the length of the stroke of the needle 36.
In order properly to guide the fabric upon the table 1, and to support said fabric against the vertical upward thrust of the needle 36, I provide a small slide plate 44, preferably having a smoothly polished upper surface, set into the table 1 and flush with the surface thereof, on either side of the opening 45 in the corresponding vertically aligned lower Slide bearng 5o. 'The presser' rod 51 is Slid- 'ably mounted in said bearings 48 and 50,
and carries fat its lower end the presser foot 52, which is adjustably and detachably secured thereto,` by means of the screws 53. The horizontal portion l52a of the presser foot 52 is bifurcated, with the outer limb thereof wider than the inner limb; said two limbs being inbperative alignment with the needle 36, and straddling the same, in the manner shown in Figures 1 and 3.
In order to retainthe presser rod 51 against rotation, there is provided a vertical slot 54 in the bearing 47, and a guide pin 55 extending through said guide slot 54 and fixed in the rod 51. The helical compression spring 56, surrounding the rod 51', is interposed between the upper part of the yoke 49 and an adjust- 7able collar 57 xed to said rod 51 by means of theset screw 58, thereby urging said presser foot 52 downwardly at all times, against the upper surface of the fabric, in a yieldable manner. The handle 59, pivoted at 60, is provided with a finger 61, which is adapted to extend into a suitable recess in the rod 51, thereby to` engage said rod and to lift said rod 51 upwardly when the handle 59 is turned outwardly or rearwardly in the direction of the arrow 62, thereby to raise the presser foot 52 out of operative engagement with the fabric. a
In order to feed or advance the fabric beneath the presser foot 52 intermittently, there is provided the bifurcated feeder foot 46, having its upper surface toothed, with the teeth inclined rearwardly; said feeder foot 46 straddling the needle 36, as shown in Figures 2 and 3. In order simultaneously to impart to said feeder foot 46 a horizontal as well as a vertical reciprocating movement, said feeder foot 46 is carried by an arm 63, which is rigidly connected to a cam arm 64. through a common integral web 65. The two arms 63 and 64 are pivoted upon a common pivot 66, carried at its ends by the pair of similar arms or levers 67 and 68, which are carried by a common rocker shaft 69. The rocker shaft 69 is journalled within a pair of suitable bearing blocks 70 and 71, fastened to the underside of the table or plate 1. The rocker shaft 69 is operatively connected to a second rocker shaft 72, through the rocker arms 73 and 74, and the link '7 5. The rocker shaft 72 is journalled within suitable bearing blocks 76 and 77, which are also secured to the underside bearing blocks 76 and 77, which are also secured to the underside of the table or bed plate 1, and in turn carries a' follower arm 78, having a follower roller 79 rotatablV mounted at its end. The follower 79 is adapted to ride on any one of the several eccentric cams 19 to 23 inclusive. ,l v
By this means, the rotationof the main shaft 7 will impart a rocking or oscillatory I .v niotion to the shafts 72 and 69 respectively,
thereby causing said arm 63 and hence the feeder `foot 46 to oscillate to and fro in the direction of thekarrows 80 and 81, with each stroke of the machine, and hence with each stroke of the needle 36. yThe length of the horizontal feeding movement or stroke-of the feeder foot is determined by the choice of the cam discs 19 to 2.3 inclusive.
In order to raise the feeder foot 46 upwardl a slight distance, into engagement with t e fabric, during the forward or operative stroke of said foot 46, (in the direction of also fixedly secured to the plate 1. Thus, as
the arms63 and 64 are oscillated to and fro, by the rocker arms 67 and 68, the arms are also raised and lowered simultaneously by the cam 83, thereby imparting to the feeder foot 46 simultaneous horizontal and vertical reciprocating movements. This construction is best shown in Figure 9.
In Figure 10 there is shown a modified form of a feeder foot cam, for raising and lowering the arms 63 and 64, which cam 84 is pivotally mounted upon a support 85, at' a point 86, and has its lower end restin upon a horizontal guide flange 87, also carried by. said support 85. In this modified construction, the follower roller 82, after passing Vover the extreme forward or pivoted end of ange 87. The follower roller 82 then returns along the guide ange 87, raising the cam 84, as it passes beneath the lowermost end thereof. The cam 84 drops into position again by gravity, and permits the roller 82 toride over the same, in the forward direction again. mounted cam, or switch cam, construction, all backward drag upon the fabric is eliminated, since the feeder foot 46 is disengaged from the fabric abruptly at the extreme end of the forward or operative stroke thereof. By properlykadjusting the position of the cams 19 to 23, inclusive, upon the main shaft 7, the stroke of the feeder foot 46 may be so synchronized with the movement of the needle 36 as to impart to said feeder foot 46 a forward movement in the direction of the arrow 8O during the time that the needle is in the lower position and out of engagement with the fabric. Suitable springs, not shown in the drawings, may be interposed between the shaft 72 and a suitable stationary or rigid point on the machine, for maintaining said shaft under a constant torsional strain, thereby to retain the follower.
By means of this pivotally roller 79 against any one of the cams 19 to and is thus carried through the fabric with each stroke of the needle, in the form of a closed loop, having one side of the loop within the needle and having the other side of the loop on the outside of the needle, as shown in Figure 6. The end of the needle 36 is bevelled as at 89, thereby causing said needle to penetrate the fabric more readily and also causing the yarn 88 to be positioned upon the same side of the needle at all times, as also shown in Figure 6.
In order to retain the loop 90 in position, while the needle 36 is being withdrawn, and in order subsequently to cut said loop at the top, after said needle has been withdrawn from the fabric, I provide a novel rotary loop retainer and cutter 91, of a suitably tempered spring steel, whichis secured to the boss 92, by means of a series of screws 93, said retainer and cutter being provided with a spring blade 94, extending outwardly of the hub portion 95 thereof, in a spiral formation, and having a rounded or dull inner re- .tainingA edge 96, shown in enlarged section in Figure 8, over a suitable portion of its length, and having the sharp cutting edge 97, along the inner portion of said blade, as shown ill enlarged section in Figure 7. The combined retainer and cutter is rotatably mounted upon a stud shaft 98, which is adjustably mounted in a suitable slot 99, in a lower pendant bracket 100, carried by the horizontal housing portion 4, whereby the vertical height of said retainer and cutter may be adjusted to accommodate the height of the needle and hence the particular height of the loop 90. The stud shaft 98 also carries a sprocket wheel 101, whereby said rotary retainer and cutter may be revolved, and sprocket chain 102 is passed over said sprocket wheel 101, as well as the sprocket wheel 31 carried by the outer end of the horizontal shaft 28, and a suitable idler take-up sprocket wheel 103, thereby causing said retainer and cutter 91 to revolve in timed relation to the shaft 28 and hence in timed relation to the needle 36. In order to permit the adjustment of the position of the idler take-up sprocket wheel 103, when such adjustment is required by the adjustment of the height of the retainer and cutter 91, and the sprocket wheel 101, the stud 104 is also adjustably mounted in a suitable slot 105, as shown particularly in Figure 1.
By properly adjusting the position of the Y' sprocket wheel 31 upon the shaft 28, the rotary movement of the retainer and cutter 91 may be so timed with respect to the stroke of the needle 36 as to cause the end of the blade 94 to engage the loop 90, in a manner shown in Figure 6, just as the needle reaches its uppermost position, thereby causing said loop to be retained by the rounded edge portion 96 of said blade, while the needle 36 is on its downward or return stroke,- and thereafter '1. causing the sharp edge 97 of said blade to cut saifd loop so as to form the desired open ended tu t.
' In Figures 11 and 12 I have shown a modified construction in the loop cutting means. In this modified construction the rotary loop retainer and cutter and the pendant bracket 100 are eliminated, and instead there is provided a' housing head 112. In this modification there is aneccentric 113 provided on the end of the upper shaft 28 carrying a suitable eccentric in or screw 114.v To the head 112 is adjusta ly secured the slotted arm 115, by means of the two screws 116 passing through a suitable slot 117. The lower end of the stationary arm 115 carries a bearing 118, in which is journalled a suitable pivot pin or shaft 119. To one end of this pivot pin or shaft 119 is rigidly secured, by any suitable means, a cutter arm 120, while to the other end thereof is rigidly secured, also by suitable means, the actuating arm 121. To the cutter arm 120 is adjustably secured a thin and oscillating cutting blade 122, by means of the screws 123, while a stationary blade 124 having the lower cutting edge 125 is rigidly secured to the stationary arm 115, by means of the screws 126. The actuating arm 121 is operatively connected to the eccentric pin 114 by means of an adjustable connecting rod l.
127 and a pin or screw 128. The adjustable connecting rod 127 is composed of an upper and a lower member 129 and 130 respectively, each provided with a suitable slot 131, which are secured to each other by means' of the two screws or other detachable fastening means 132.
Thus, with each stroke of the machine and hence with each revolution of the shaft 28, the cutting arm 120 will be deflected by the eccentric pin 114, thereby causing the blade 122 to oscillate to and fro, past the stationary cutting edge 125, thereby to effect a shearing action between said stationary cutting edge 125 and the movable cutting edge 133 of the cutting blade 122. The movable cutting blade 122 as well as thestationary blade 124 are so positioned with respect to the needle 36, as to cause said movable blade to engage and retain the loop of yarn hanging over one side of the needle and to bring the same between the two cutting edges 125 and 133, thereby severing the loop. The presser foot mechanism in this particular modification of my invention may be carried by the cover plate 134 of the frame head '112, as shown particularly in Figure 12.
In order to adjust the height of the cutting mechanism with respect to the needle 36, and
in order to adapt the same to varying heights of loops, it is merely necessary to raise or lower the stationary arm 115 by means of the screws 116, and to adjust the length of the connecting rod 127 a corresponding amount. by means of the screws 132. With the aid of the adjustment screws 123, the blade 122 may formation of the loops or of the pile are immediately discovered by the operator and ma be corrected before substantial damage is one. There is the further advantage of .l
eliciency in that the operator seeing the performance of the machine is enabled to speed up operation without impairing the quality o the product. Manual access immediately can be had to any of the loops in case of slight irregularity. The machine, moreover', does not exert any pressure upon the loops, as would a machine forming the loops on the side of the fabric which rests on the table. Inasmuch as the loop is not formed through the thickness of the table, my machine renders possible the formation of the shortest possible loop or tuft, the thickness of the retaining pin or shear being the only limitation as to length.
While the drawings of the present application show a single needle machine and the specification concerns itself with the descripe tion of such a machine, itwill be very obvious that a multiplicity or a battery of needles and associated loop retainers and cutters might be utiliz-ed and that the plurality of needles might be independently operated or might be operated in unison from a common actuating means.
Y It will also be understood that the term table as used in this application is to be interpreted in its broadest sense. In so far as the present invention is concerned, it is immaterial whether a solid, table-like support member is utilized or whether equivalent devices are used, such for instance as skeleton frame members or other apparatus which is the full equivalent of a table. The primary consideration is to properly support the fabric while it is being operated upon and any device for effecting such support is considered to be a table within the scope of the appended claims. l
