transverse vertical sectional view of a part of the counting cylinder and two of the lifting blocks carried thereby. Fig. 12 is a top. I

view of the cylinder partly broken away, when it is in the position shown in Fig. 4.

Similar reference. characters designate similar parts in the different views.

1 designates the main driving shaft of the machine, which may be rotated by means of a crank 2, or which may be driven by a pulley 3, when a clutch 4 operated by a; handle 5, is thrown into operative position. which meshes with a spur gear wheel 7, which is secured fast to a horizontal shaft 8 rotatably mounted in the frame 9.

A horizontally reciprocative carriage 10, Fig. 1, of the usual type is reciprocated over two inclined needle racks 11 and 12, by

means of a rod 13 connected to a cross head 14, which is omitted in Fig. 2, but which, as shown in Fig. 1, is reciproca-tive on two horizontal parallel bars 15, which are sup- Secured on the shaft 1 is a pinion 6 ported by the frame 9. A pitman 16 has its ends pivoted respectively to the head 14 and to a radially adjustable crank pin 17 carried on a bar 18 which is secured to the spur gear wheel .7. The front needle rack 11, inthis particular type of machine, is adapted for being longitudinally shifted back and forth for cross stitching, by means of a cam 19 which is secured fast to a horizontal shaft 20, Fig. 1, rotatably mounted in the frame 9 and having secured to its forward end a ratchet wheel 21 provided on its periphery with-two 'sets of ratchet teeth, 22 and 23, Figs. 3, 4 and 5, which are adapted to be engaged respectively by means of two pawls 24 and '25 whichare pivoted to a horizontally reciprocative controlling head 26, which is slidably mounted in two bearings 28 by means of two horizontal parallel bars 27 with which said head 26 is provided. The needle operating mechanisms for the racks 11 and 12 are carried in the boxes 29 with which the carriage 10 is provided in the usual manner. 30 designates the usual cotton or yarn carrying boxes which are slid respectively along the slide supports 31,

designated by 40. A coil spring 41, Fig. 4

encircles the stud 40 and normally" swings,

the yoke 39 in a clockwise direction, so that the stop pin 38 will engage the rod 35 on the forward movement of the carriage 10. To rock the yoke 39 counter-clockwise so that the stop pin 37 will engage the rod 34, said yoke is provided with a crank 42, Fig. 3,

which is connected by a link 43 with a bar 44 which is pivoted on a horizontal stud 45 secured to the frame 9, see Figs. 3 and 4.

The free end of the bar 44 is swung upwardly by means of a block 46 which is secured to an endless chain 47, Figs. 3 and 4, which is used, as hereinafter described, for pattern and counting purposes. The chain 47 is mounted on a sprocket wheel 48, which is secured to a sleeve 49, Fig. 6,

which is rotatably mounted on a stud 50,

secured horizontally to the frame 9 and which sleeve in turn has secured to it a ratchet wheel 51 which is adapted to be engaged by a pawl 52, which is pivoted to the head 26. When the said head is reciprocated, the pawl 52 on its rearward movement will engage the ratchet wheel 51 and will move it clockwise one tooth, thereby rotating the sprocket wheel 48 one tooth, and thereby advancing the chain 47 one link in the same direction.

Reciprocation of the head 26 is obtained by means of a horizontal rod 53,. Figs. 2 and 3, which has its forward end pivoted to the head 26, by means of a vertical pin 54 and has its rear threaded end fitted in a threaded hole provided in an eccentric strap 55 which embraces an eccentric 56 which is secured to the upper end of a vertical shaft 57, Fig. 3, rotatably mounted in the frame 9 and having secured fast to its lower end a bevel pinion '58 which meshes with a bevel gear wheel 59, having twice the diameter of the pinion 58, and which is secured fast to the shaft 8..

By means of the gearing just described, the eccentric 56 effects two complete reciprocations of the controlling head 26 for each complete reciprocation of the carriage 10. The eccentric 56 is, so set as to effect a forward movement of the controlling head 26 before and after the boxes 29 on the carriage are in operative position with reference to the needle racks. This arrangement permits the rack 11 to be shifted in both directions without injury to the needles.

I will now describe how the chain 47 controls the rocking of the cam shaft 20 by which the needle rack 11 is shifted. As is shown in Fig. .3, the chain 47 is provided the pawl 24 so as to lift said pawl out of engagement with the teeth 22 of the ratchet wheel 21, and to bring into engagement with the teeth 23 thereof the pawl 25, which result is accomplished by means of a coil spring 63 which connects the

pawls

24 and 25, and by its tension always tends to draw them toward each other and into engagement with the ratchet wheel 21. A spacing pin 64 fastened to the pawl 24 and having its lower end free from, but adapted to bear against the pawl 25, holds the pawls far enough apart, at all times, so that both pawls may be free from the ratchet 21, when the pin 60 is bearing against any one of the medium width links in the chain 47.

With the chain 47 having one of its narrowest links engaging the pin 60, the pawl 24' will be disposed so as to engage the ratchet wheel 21 and thereby rock the cam shaft 20 upon the forward movement of the controlling head 26. At this time the pawl 25 will be free from said wheel, as shown in Fig. 5, the pawls being held in these positions by a coil spring 64, which is fastened to the pawl 24 and has its lower end secured to the frame 9.

When the chain 47 is positioned with any one of its medium width links engaging the pin 60, both

pawls

24 and 25 will clear the ratchet wheel 21 and the rack 11 will not be shifted in either direction on the forward movement of the controlling head 26.

lVhen the chain 47 is positioned with any one of its widest links engaged with the pin 60, the pawl 24 will clear the wheel 21 and the pawl 25 will engage said wheel upon the forward movement of the controlling head 26 and will rock the cam shaft 20 clockwise,

thereby shifting the needle rack 11 in the direction opposite to the direction in which it was shifted through the intervention of the pawl 24.

It will be understood that if a chain 47 should be used having all links of the me dium width, the pawls would not engage the ratchet 21 and the rack 11 will not be shifted.

There is also provided, preferably, another anda shorter endless pattern chain 65, which, like the chain 47, has links of different width for supporting the. pin 60 in different positions to'efl ect rocking of the shaft 20 as already described, and which is mounted on a sprocket wheel 66 which is secured fast to a sleeve 67, Figs. 5 and 6,

- is adapted to be engaged by a pawl 69 which is pivoted to the controlling head 26 along which is rotatable on the sleeve 49 and has secured fast to it a ratchet wheel 68which 5 side of the pawl 52. When said controlling head is moved forward, and the pawl 69 is permitted to drop into engagement with the ratchet wheel 68, said ratchet wheel will be from being turned upon the forward move ment of the controller head 26, two pawl's, Fig. 4, pivoted-to the frame 9 and designated by 70 and 71, respectively engage the ratchet wheels 51 and 68, said pawls being normally held engaged with said ratchet' wheels by means of two springs 72 .and 73 which are secured to a pin 74 fastened to the frame 9.

I will now, describe the counting cylinderand the mechanism which actuates it and controls. its operation. 75 designates the counting cylinder which is secured fast to a horizontal shaft 76 which is rotatably mounted in an inverted U-shaped bracket 77, which is secured to the frame 9. The cylinder 75 is provided with-two annular

peripheral grooves

78 and 79, the periphery of the cylinder between saidgrooves being graduated into a number of numbered spaces, as shown in Fig. 12.

In the groove 78 are mounted a number of.

removable blocks 80, which have dove-tailed lower .ends, which are slidably fitted in the groove 78, which is also dove-tailed in crosssection. Theblocks are rigidly held in the positions to which they are adjusted by pointed screws 81, the lower ends of which are adapted to be seated respectively in a series of conical recesses 82, provided in the bottom of thegroove 78. As is shown in Flgs. 4 and 12, and also in Fig. 7, the groove 79 is also provided with similar conical recesses 82 adapted to receive securing screws 81 mounted in two stop blocks 83 and 84 respectlvely, the block 83 being located in r the groove 79 opposite the zero space in the graduated part ofthe cylinder. ()pposite to this zero space, in the groove. mounted, a space 85 being left at this point for the purpose referredto hereinafter. The graduated space, as shown in Fig. 12, is provided with a transverse groove 86, next to the zero space and connecting the

grooves

78 and 79 to permit the insertion and removal of the

blocks

80, 83 and- 84.

-A lever 87, which is secured fast to a horizontal shaft 88 rotatably mounted in the bracket 77 is provided with a downwardly turned, and with it the

sprocket wheel

66 and 78, no block is,

ing the. rear end of the lever 92, so as to I swing the pawl 69 outof engagement-with the ratchet wheel 68, by means of a vertical rod 94, the upper end of which is secured to the pawl 69, and the,lower end-0f which is fastened to a pin mounted in alongitudinal slot 96 irr the rear end of-the lever From the foregoing it will be understood that, with theprojection 87 resting on the blocks 80, the lever 87 will hold the pawl .52 out of engagement'with the ratchet 51. At such times the ,chain 47 will not be driven,

' upon the rearward movement of. the, controller head 26.- When the counting .cylin-' der 75- is disposed in the position shown in Figsr4 and 6, the pr'ojection'87 ofthe lever 87 will be in the space 85, which is opposite to the stop and lifting block 83. At this time the rear end of the lever 87 willbe lowered and the pawl'52 will be engaged with theratchet wheel 61, and said ratchet wheel will be turned on the rearward move.-

ment of the head 26, thereby driving the chain 47 step by step as long as the lever 87 is in said lower position.

When the lever 92 is supported by the block 83, the pawl 69 will be lifted free from the ratchet wheel 68 and the chain 65 -Wlll not be driven by the sprocket wheel 66 I spaceof one block so as to drop the lever 92,

the pawl 69 will engage. the ratchet wheel 68 and the chain 65 will be driven, thereby controlling shifting of the needle rack through the intermediacy of the pin 60, as described with reference to the chain 47. Thus it will be understood, there being only one lifting block in the groove 79, the block 84 in the portion which passes under the lever 92 not being high enough to lift saidv lever, that when the lever, 92 is raised, the lever 87-will be lowered and vice versa. The chains 47; and 65, will thus be alternately driven. w- I will now describe howthe chain-47 controls the operation of the cylinder 7 5. Secured fast on the shaft 76 to which the cyl-- inder 75 is secured, are two

ratchet wheels

97 and 98, "Figs. 4 and 10, havingreversel-y disposed teeth adapted to be respectively engaged by two pawls- 99 and 100, which tion at the same time.

is secured to the lower end of a vertical lever 102, Fig. 3, which is pivoted on a horizontal bolt 103 mounted in a bracket 104, which is secured to the frame 9. The upper end of the lever 102 is pivoted to a link 105, which is pivoted to the controller head 26. When the controller head 26 moves forward, the shaft 76 will be rotated, and with it the counting cylinder 75 in a direction which is dependent upon which one of the

pawls

99 or 100 is in operative engagement with its ratchet wheel.

v If the pawl 99 is engaged with the ratchet 97, the rotation of the cylinder 75 will be in a clockwise direction, as viewed in Fig. 10. With the pawl 100 engaged with the ratchet wheel 98, the rotation of the cylinder 75 will be in a counter-clockwise direction. It will be understood that both

pawls

99 and 100 should not be in operative posi- The engagement of the

pawls

99 and 100 with their

respective ratchet wheels

97 and 98 is controlled by four cams 106, 107 108 and 109, which are loosely mounted on the shaft 76, Fig. 1.

The

pawls

99 and 100 are normally drawn toward each other by means of a coil spring 110, Fig. 10. Extending horizontally to the left from the

pawls

99 and 100 respectively, are two pins 111 and 112 which are adapted to be engaged by either of the cams 106,

107 or 108 so as to hold disengaged the pawls which carry them from their respective ratchet wheels.

The cam 106 is provided with peripheral recesses 113 and 114: which, when said cam is turned to the position shown in Fig. 10,

permit the pins 111 and 112 to move to positions in which their respective pawls will be in operative positions. To swing the cam 106 to the position shown in Fig. 10, it has pivoted to it a link 115 which is pivoted to a crank 116 secured fast to a rock shaft 117, mounted horizontally in the bracket 77,

and having secured fast to its right end an arm 118, Fig, 3, which is adapted to be de- I that when the controller head 26 is reciprocated, the pawl 121 will cause rotation of the ratchet wheel 120, at such times as said pawl is engaged with said ratchet wheel. It will be further understood that, when the ratchet wheel 120 is rotated, the pins 119 will-consecutively depress the arm 118, thereby, four times, during a revolution of the ratchet wheel 120, swinging the cam 106 to the position shown in Fig. 10, thus enabling one of the

pawls

99 or 100 to rotate the cylinder 75 four numbered spaces for each complete revolution of the ratchet wheel 120, providing that other parts of the mechanism permit the

pawls

99 and 100 to swing into the operative position.

The arrangement of the parts is such that when the pawl 121 is engaged with the ratchet wheel 120, said wheel will be turned one tooth, corresponding to a part of a revolution equalto one numbered space on the cylinder 75, for each complete reciprocation of the controller head 26. To hold the ratchet wheel 120 against retraction, there is provided a pawl- 122, Fig. 3, which is pivoted on a stud 123 carried by the bracket 77, a spring 124 serving to hold said pawl in the operative position.

In order that the ratchet wheel 120 may be manually turned, it has engaging it a pawl 125, Fig. 3, which is pivoted on a bar 126, which in turn is pivoted on the shaft 76. A pin 127 mounted in the braoket77 serves to limit the downward movement of the bar 126. By lifting this bar up and forcing it down, the pawl 125 will rotate the ratchet wheel 120. Said pawl is held engaged with said ratchet wheel by means of a spring 128 carried by the bar 126.

To retract the cam 106 from the operative position shown in Fig. 10 to the position in which said cam will force apart pins 111 and 112,.the rock shaft 117 has secured to it an arm 129 to which is connected a coil spring 130, which is also connected to the stop pin 127, which for this purpose extends through the arm of the bracket 77 in which said pin is mounted.

To lift the pawl 121 from engagement with the ratchet. wheel 120 when the lever 87 is loweredinto the space 85 of the counting cylinder 75, for the purpose to be hereinafter explained, the shaft 88, to which the lever 87 is made fast,has secured to it an arm 131, Fig, 3, which, when the arm 131 is depressed, as shown in Fig. 3, swings downward one end of a lever 132, the other end of which carries a pin 133 which lifts the pawl 121 clear of the ratchet wheel 120. The lever 132 is pivoted on a stud 134 secured to the bracket 77. I

The cam 107, which is of the same form as the cam 106, is-provided with recesses 135 and 136 adapted respectively to receive therein the pins 111 and 112, to permit the

pawls

99 and 100 swinging to the operative positions at the proper times. To swing the cam 107 from the position shown 1n Fig. 9, in which position the pins are held out of'the operative positions, said cam 107 has pivoted to it a link 137, which is also pivoted to a lever 138, pivoted on the stud 45, and adapted to be engaged by a pm 139 which is carried by the long chain 17. When said pin swings the lever 138, upon nae - trically to the cam 108.

145, when moved forwardly, will, one or the driving of the chain 47, the cam 107 will be swung to the position shown in dotted in solid lines in Fig. 9.

The cams 108 and 109 are employed to reverse the direction of rotation of the cylinder 7 5. To efiect this the cam 108 is pro-.

vided with two recesses 142 and 143, Fig. 8, adapted to respectively receive the two pins 111 and 112 so as to permit one, only, of the

pawls

99 and 100, to pass at one time to the operative position. The recesses 142 and 143 are, therefore, arranged so that, when the cam 108 is in theposition shown in solid lines in Fig. 8, the pin 111 is free to swing to the operative position, while the pin 112 is held from moving to the-operative position. -When the cam 108 is swung to the position shown in dotted lines in said .figure, the pin 112 will be permitted to move to the operative position and the pin 111 will be held frommoving to such position.

The determination of which position the cam 108 is to occupy is controlled by two pawls 144 and 145, which are pivoted on the stud 101 and are normally forced toward each other .by a coil spring 146, and are adapted respectively to enter two peripheral notches 147 and 148 in the periphery of the disk 149, which is secured concen- The pawls 144 and the other, engage the disk 149 and turn it, with the cam 108, to place one or the other of the pins 111 or 112 in the operative position. Which pawl 144 or 145 engages the disk 149 is controlled by the cam 109, which is adapted to engage two

pins

150 and 151 carried respectively by rigid extensions 152' and 153 of the pawls 144 and 145. The cam 109 is @provided with two peripheral. recess'es 154 and 155' adapted to receive respectively ment of said recesses being such that, when the cam'109 is in the position shown in Fig. the pin 150 will be held, while the pin 151 will be free to enter the recess 155, thereby permitting the pawl 145 to engage the disk 149, so as to turn it in a clockwisedirection upon the forward movement of the pawl. When the cam 109 is shifted counterclockwise from the position shown in Fig. 7, the pin 150 will enter the recess 154, while the pin 151 will be held out of the recess 155.

The pawl 144, at this time, can engage'the disk 149 upon the forward movement of the pawl. Two spring actuafted pawls 156 and 157, pivoted on a stud 158 secured to the bracket 77, respectively in it-a pin 161,

the lever the

pins

150, and 151, the arrange- "p limit the counter-clockwise movement of the cams 108 and 109, by entering notches 159 and 160 provided respectively in said cams.

' For reversing thedirection of rotationof the counter cylinder, which is effected by the

pawls

99 and 100 operating inthe two

ratchet wheels

97 and 98 through the intermediacy' of the cams 108 and 109, as

above described, the cam 109 has mounted which is located in a slot 162 provided in a bar 163, which is pivoted on a pin 164 secured in the bracket 77. v The

blocks

83 and 84 extend laterally to the right of the. cylinder 7 5. When the cylinder is rotated clock wise to the position shown 'in Fig. 7, the block 83 will have I struck the bar 163 and swung it and the .cam 109 to the position shown in Fig. 7.

The forward movement of the stud 101 with the pawls 144 and 145 will cause the pawl 145, which is in operative position by reason of the pin 151 carried thereby being in the recess 155 of the cam .109, to turn the cam 108 to the position shown in dotted lines in-Fig. 8, at which time, the pawl pinv 112 will be in the recess'143'of the cam 108, and the pawl 100 will be engaged with the ratchet wheel 98. The forward movement of the controller head 26 will retract rearwardly the pawl 100, thereby rotating the ratchet wheel 98, and with it the cylinder 75, in a counter-clockwise direction. Succeeding reciprocations of they pawl 100,

through the intervention of the

stud

101, 102, link 105 and controller head 26 will cause the counting cylinder 75 to be rotated counterclockwise until the block 84' strikes the bar 163 and swingsit, and the cam 109, until the pin 150 can enter the notch or recess 154 in said cam, at which time the pin 151 will have been forced by the cam 109 so that the pawl 145 will be disengaged from the disk 149. The pawl 144 will then engage the disk 149, and the cam 108 will be shifted to the position shown in solid lines in Fig. 8, at which time the pin 111will enter the recess 142, and the with the ratchet wheel 97, thus reversing the movement of the said ratchet wheel and with it the cylinder. 75. The cylinder. 75 will now rotate clockwise,

original position, shown in Fig. 7.

The operation of my invention is as follows:' The driving shaft 1 having been started in the manner hereinbefore described, reciprocation of the carriage 10 will be. effected by the mechanism already described, and the controller head 26 will be reciprocatedby means of the eccentric 56, thereby effecting shifting of the rack 11 through the intermediacy of the pawls 24 awl 99 will be brought into engagement as viewed in Fig. Y 6 and Fig. 7 until the block 83 strikes the bar 163 and swings it and the cam 109 to the- 20 of the

pawls

99 and 100 to be forced to the time the lever 92 will rest on the lifting and V stop block 83, which will be in the position shown in Fig. 7, in which position the cam 109 will be forced to the position shown in Fig. v w

At starting the ratchet wheel 120 will be turned to the position shown in' Fig. 3 in which the arm 118 will be depressed by one of the pins '119, thereby rocking the shaft 117 to the position shown in Fig. 10, in which position the cam 106 will permit either one operative position with reference to the

ratchets

97 and 98 which drive the shaft 76 in one direction or the'other, thereby rotating the cylinder 75 in case that the cam 107 is in the dotted position shoWn in Fig. 9. Which one of the

pawls

99 and 100 will engage its ratchet wheel 'will depend uponthe position of the cam 108, andas already described, the position of this cam is dependent upon the position of the cam 109. With the-cam 109 in the position shown inFig. 7,

which is the starting position, the cam 108 will be turned to the position shown in dOt" t'ed lines in Fig. 8, therebyjpermitting the pawl 100 to engage the ratchet wheel 98.

At the time of starting the long chaln 47 is set in a position on the sprocket wheel 48 I such that the pin 139, carried by the chain 47, will strike against and will have lifted the cam 107will be in the dotted position shown in Fig. 9.

' Upon the rearward movement. of the'h'ead 26, the lever 87 being in the space 85 of the cylinder 7 5, in the starting'position, the .paWl

. 52 being in engagement-with the ratchet wheel 51, said ratchet wheel will be turned the distance. of one tooth, thereby advancing the chain 47 one link so that the pin 139- releases. the arm- 165 of the lever'138,

- which lever is immediately retracted by the I spring 140, Fig. 3, to the'position shown in Fig. 9, in which position the cam 107 will have been swung to the position'shown in solid lines in Fig. 9, thus holding apart-the pins 111 and 112, which are carried respectively by the

pawls

99 and 100, and thereby preventing the engagement of said pawls with

theratchet wheels

97 and 98 until the arm 165 of the lever 138 has again been engaged liy the pin 139.

As the pawl 52 is'retracted by the head 26, the stud 101, carried by the lever 102,

andmoved forward by the link 105 when the the arm 165 of the lever. 138.

head 26 inoveslrearwardly, will be carried forward as will the pawls 99 and .100,which are carried by said stud.- Thus, while the pin 139 inthe chain 47 is carried from the initial position, in which it supported the arm 165 in a raised osit ion, the cylinder will not be advanced one number, for the reason that the spring 140 will have re tracted the leverl38 to the position shown in solid lines in Fig. 9, before the head 26 starts on its forward movement and retracts the

pawls

99 and 100.

For the above reasons the chain 47 will be advanced bythe reciprocation of the head 26 until the pin 139 again strikes and raises During the time that the chain 47 is making the circuit, the machine will be knitting the border of the garment. During this time, the lever 87 will be in the lower position shown in Fig. 3, thereby permitting a spring166, which is connected to the-arm 131 and to a pm 167, to swing downward the arm 131,

thereby lifting the pawl 121 out of, engagement with the ratchetwheel 120 by means of the lever 132. Said ratchet wheel will, there fore, remain in the position shown in Fig. 3 with one of the pins'119 holding depressed the arm 118.

After the border of the garment has been completed, the pin 139 of the chain 47 will have raised the arm 165, thereby swinging the cam 107 to the positionshown'in'dotted lines in Fig. 9. Upon the next forward movement of the controller head 26,-the pawl 52 will slip over the ratchet wheel 51, but the pawl 100 will be forced into engagement as viewed in Figs. 6, 7 and 10. This movement of the counting cylinder 75 will cause the pawl 52 to be raised clear of the ratchet wheel 51 by reason of the lever 87 being lifted out of the space of the cylinder. At the same time, the lever 92 will drop from the lifting block 83, thereby permitting the pawl 69 to engage the ratchet wheel 68.

Upon therearward movement of the controller head 26,,the pawl 69 will turn the ratchet wheel 68, thereby driving the short chain 65 through the intermediacy of the sprocket wheel 66, which is secured on the sleeve 67 that carries the ratchet wheel 68. The knitting of the body of the garment will now begin. v

Succeeding reciprocations of the head 26 will drive the short'chain 65 step by step, thereby rotating the cylinder 75 in a. counter clockwise direction, as viewed in Figs. 6 and 7, until the stop block 84 on said cylinder 1 strikes the bar 163 and forces it and the cam as hereinbefore described, will cause the cam 108 to be shifted to the position shown in solid lines in Fig. 8, in which position the pawl 99 will be brought into engagement with the ratchet wheel 97 andthe pawl 100 will be disengaged from the ratchet wheel 98.. These movements of the reversing mechanism will cause the "reciprocations of the controller head 26 to impart a step-by step clock-wise movement to the cylinder 75 and the

ratchet wheels

97 and 98, as viewed in Figs. 7 and 10. This step by step movement will be controlled, however, by the cam 106, which in turn will be controlled by the ratchet wheel 120 and thearm 118. As soon as the cylinder 75 moved one number counter clockwise from the initial position, the 7 pin 119 will have moved from the arm 118 owing to the action of the pawl 121, which will have been permitted to engage the ratchet wheel 120 as soon as the lever 87 was lifted by the first step of the counting cylin der 75. As soon as the arm 118Was released from the pin 119, the spring 130 will have rocked the shaft 117 in a counter clockwise direction, as viewed in Fig. 10, until the cam 106 engagedand forced apartand away from the ratchet wheels 97 and .98 the

pawls

99 and 100.

Succeeding oscillations of the lever 102 by the controller head 26 will effect step by step movement of the ratchet wheel 120 through the 'intermediacy of the pawl 121, until the next pin 119 -strikes and depresses the arm- 118, at which time, the cam 106 will be swung to the position shown in Fig, 10, thereby permitting either one of the

pawls

99 or 100 to engage its ratchet wheel, thereby imparting. rotary movement to the cylin der 7 5 a distance of one number.

From the foregoing it will be understood 7 that for each complete revolution of the ratchet wheel 120, the counting cylinder 75 will be turned four numbers for the pins carried by said ratchet wheel.

\ When. the'cylinder 75 starts on its reverse clockwise movement, it will continue this movement. until the op and lifting" pawl 83 has reached the initial position shown m Fig. 6, and also in Fig. 4. At' this time the lever 87 will drop into the space 85, thereby permitting the pawl 52Ito engage the ratchet Wheel 51. At'the same time, the lever 92 will be lifted by the block 83, thereby disengaging the pawl 69 from the ratchet wheel 68. a

During the time that th e small chain 65. has been running, the body of the garment will have been knitted, and the pin 139 will have held the arm 165 in the elevated position, the chain 47 having stopped its move ment just prior to the beginning. of the travel of the chain 65. r a

As soon as the lever 87 has dropped into the space 85, the pawl 121 will be lifted from the ratchet wheel 120. Upon the first rearward movement of the head 26, the pawl 52 will turn the ratchet wheel 51 one tooth, 1

thereby driving the chain 47 one link, so; as to again move the pin 139 awayfrom the arm 165 in the manner already described,

after which the various operations described put into operation the box 30 which carries the cotton. As soon as the chain 47 has advanced another link, the'block 46 will pass from under the bar'44, and the yoke 39 will be retracted by the spring 41 to the position for knitting yarn.-

The block 46 may be placed at any desired point on the chain 47. In the relative position which it bears to the pin 139, as shown in the. drawing,Fig. 3, the block 46 will cause thecotton thread to be inserted by the knitting mechanism adj acent.

to the beginning of the border. If it is 'desired to have the cotton thread inserted in about the middle of the border ,of the garment, the'pin 139 may be placed in-a hole 168, which is provided in one of the links of the chain 47, almost diametrically opposite from the block 46, as shown in Fig. 3.

From the above description, it will be understood that, upon starting the machine, the counting cylinder 75 is turned with the shaft 76 to .the position shown in Figs. 4 and 6.- Upon the driving shaft 1 being driven, the chain 47 having been placed on the sprocket wheel 48, with the pin 139 holdin the arm 165 in the elevated position, t e long chain 47 will first be made to travel a circuit, during which time the after which the short chain 65 will take up the workof controlling the'pattern of the knitting, and the counting cylinder will begin to rotate in a counter clockwise direction, as viewed in Fig. 6, the step by step rotation of the counting cylinder being controlled by the pawl and ratchet niechanism, which is operated by the lever 102.

'After the counting cylinder 75 has been rotated to a position in which the stop block- 84' will have shiftedthe reversing mechanism, the counting cylinder willv reverse its direction of movement from'a counter clockwise to a clockwise direction, and will continue this clockwise movement until itv has returned to the initial position shown in Fig. 6, at which time it will stop, and one garment Willhave been completed, so far as the knitting of the body and border. is concerned. The chain 47 will then begin to travel, and the knitting of the border for I another garment will commence.

It will be understood that blocks 80 may be omitted from the groove 78 to suit the style of knitting desired. It will also be understood that some of these blocks or others like them may be inserted in the groove 79. Instead of having the chains 47 and 65 working alternately, it may be desired, for

certain patterns, to start the machine with the counting cylinder 75 not in the initial position shown in Fig. 6, and with the pin 139 out of contact with the arm 165 of the lever 138. With the machine started in this manner, the cylinder would not run, nor would the chain 47, and the work produced would be all of one style or pattern, such as would be produced with the use of the small chain alone. Or, if desired, the groove 79 could be filled with blocks, in which case the large chain and cylinder would work ened, will bring the blocks to accurately correct positions.
