IMPROVEMENTS ON KNITTING MACHINES

Revendications

Claim 1st In a knitting machine provided with a revolving or reciprocating cam plate, stationary cams attached thereto, in combination with adjustable cams k held by vertical slots made in the cam plate, and so arranged, in connection with the stationary cams g, that the vertical adjustment of the cams h is effected upwardly by the heel of the passing needles, and downwardly by their own weight. 2nd Two or more yarn feeders adjustably held on a spindle suspended over the centre of the cylinder and revolving therewith, the said yarn feeders receiving the thread from a point over the centre of the cylin¬der, in combination with circular grooves or guides in the face of a stationary disk suspended over the centre of the cylinder, the said grooves being connected by a slot provided with an adjustable gate or gates arranged to throw the yarn feeders from one groove to the other, for the purpose of throwing the thread carried by them in and out of action. 3rd In two or more revolving yarn feeders, the combination of one or more circular guides or grooves arranged to hold the yarn feeders in and out of action as desired,and provided with a passage way or ways leading from the groove and having an adjustable gate or gates arranged to move one yarn feeder out of action, while simulaneously throwing into action another to take its place. 4th In an arm extending over the centre of the cylinder, the combination of a bobbin frame having a central hub or boss pierced with a hole and pivoted in a hole, through the arm over the centre of the cylinder, and revolving with the cam cylinder, cog ring or needle cylinder, for the purpose of delivering the yarn from the centre of the machine without allowing the yarn leading from the different bobbins to twist. 5th In knitting machines in which the needles are held and work longitudinally within slotted passage ways in the needle cylinder or bed, the combination of a cylindrical enlargement made, in the top of each slotted passage way, the necessary depth without enlarging the slot on the outside surface of the cylinder or bed. 6th The stitch regulated by the adjustment of the needle cylinder, the adjustment of the cam cylinder or adjustment of the cams, the combination of the adjustable tension support connected to a post held in the bearing or bearings, which will permit of its longitudinal adjustment, and through it a vertical adjustment to the needle cylinder, cam cylinder or cams, by which the length of the stitch may be regulated, while the machine is in operation. 7th In combination with a knitting machine, an oil cup arranged for the purpose of lubricating the yarn while it passes from the bobbin to the needles. 8th In reversing earns, treadle mechanism arranged to impart a rotary movement to the ma¬chine, in combination with adjustable stops, by which the stroke of the treadle may be shortened, and a consequent oscillating movement imparted to the machine is required when operating heel and toe work. 9th In reversing cams, provided with a spur wheel keyed to its main driving shaft, the combination of a pitman, driving motion from treadle or other newer and having formed, on one of its sides, a rack arranged to gear with the said spur wheel, for imparting an oscillating movement to the main driving shaft, and through it to the machine as required, when operating it for heel and toe work. 10th In striping and ribbing attachments, the combination of the pivoted arms H 1, for carrying the said attachments and so arranged, in connection with the cylinder of the machine, that either one may be brought separately into action therewith or both thrown out of its way. 11th In mechanism for feeding two or more colours, the combination of longitudinally adjustable yarn feeders W placed at an angle to each other, so that the poin t occupied by the feeder directing the yarn to the needles will be instantly occupied by the other feeder as the first one is withdrawn. 12th In mechanism for feeding two or more colours, the combination of longitudinally adjustable yarn feeders arranged at such an angle to the cylinder needles, that the one thrown forward to feed the yarn to the needles will be below their points, while the other is located above their points. 13th In an arm extending over the centre of the cylinder, the combination of a bobbin frame pivoted over the centre of the cylinder, and revolving with any rotating part of the machine, the bobbin frame being pierced with a hole to permit the yarn to pass from the centre of the machine to the needles, without allowing the yarn from the different bobbins to twist. 14th As a new article of manufacture, a knitting machine needle in which the heel or projecting end is formed by a fold having an open space between the material. 15th In a machine in which the main driving wheel has more or less teeth than the cog ring with which it meshes, the combination of a pattern ring 7, for the purpose of indicating the number of rounds knitted. 16th A spindle 13 geared to the main driving shaft so as to move one tooth at each revolution of the main shaft, in combination with an indicating ring 11,extending around the base of the machine and operating in conjunction with a pointer 8. 17th In an indicating ring 11 placed on top of the cog ring, the combination of a hold fast ring 15, arranged to hold the indicating ring and cog ring in position. 18th In reverse knitting cams, the combination of cam pieces operated by the heel of a passing needle, for the purpose of throwing the said needle in and out of action. 19th In a projection or arm to engage with the ribbing dial, the combination of a thumb screw connected with and arranged to operate the projection or arm for the purpose of adjusting the needles in the ribbing dial.20th In a revolving bobbin frame held over the centre of the machine, a yarn feeder S attached to the cog ring or cam cylinder, and having the eyes u ti, for directing the yarn to the needles, connected together by a slot t, the eye ti being protected by a hook s to hold the yarn in position, after having been slipped through the slot in the eyes u t1. 21st In an arm extending over the centre of the machine for holding the ribbing or striping attachment, a head Qi connected to the revolving portion of the said attachment and provided with a slot Q2, in combination with a hinged arm attached to the cog ring or other revolving portion of the machine. 22nd In an arm extending over the centre of the needle cylinder, the combination of the yarn feeder F having the revolving pattern wheel u, and provided with the feeding eyes v v1, for feeding coloured yarn to produce longitudinal stripes. 23rd Two or more yarn feeders adjustably held on a spindle suspended over the centre of the needle cylinder, the said yarn feeders receiving the thread from a point over the centre of the cylinder, in combination with circular grooves or guides supported over the centre of the cylinder, the said grooves or guides being connected by a slot or slots provided with an adjustable gate or gates, arranged to throw the yarn feeders from one groove to the other, for the purpose of throwing the thread carried by them in and out of action
