Patented Nov. 24, 1931 UNITED STATES PATENT OFFICE SIGNOR TO TEXTILE MACHINE WORK DURATION OF PENNSYLVAN OF WYOIMISSING, .BEEN'NSYLVAINIA, A COB- THREAD CARRIER BOD CONTROL MECHANISM Application filed April 14,
This invention generally relates to straight knitting machines, and more particularly to controlling means for their yarn guide rods.
It is well known, that the addition of con- 5 trolling means for yarn guide rods, intermediate the usual end stops of a straight or full fashioned knitting machine, makes it possible to produce various ornamental effects, such as plating, reenforcin and split seams,
10 in the fabric knitted there y;-and that dif ferent types of controlling devices have been devised for this purpose. One such device consisting of plain stop nuts which are adjustably positloned by a rcversely threaded ll spindle whose direction of rotation is controlled by pattern mechanism.
The primary object of my invention is to provide an improved device of this general type, capable of variably .controlling all the 2 rods of the machine, singly or in combination; and I accomplish this by providing in place of plain rod stops as heretofore, novel rod stop units which individually afi'ord vae ried and selective rod control.
The invention comprises the novel elements, features of construction and arrangement of parts in cooperative relationship as hereinafter fully disclosed by the detailed description and accompanying drawings of 30 one embodiment thereof.
In the accompanying drawings:
Fig. 1 is a partial front elevational view of a well known full fashioned stocking knitting machine, having my invention applied thereto.
Fig.2 is a cross-sectional view taken as indicated by the arrows 2-2 on Fig. 1.
Fig. 3 is a fragmentar plan view taken substantially as indicated y the arrows 33 on Fig. 1.
Fig. 4 is a partial front elevational view of one of the rod stop units, with the retainin plate removed.
nly such parts of a well known full fashioned stocking knitting machine have been indicated that directly cooperate with my invention in producing ornamental effects in the knitted fabric, as mentioned.
Referring to the drawings, 5 indicates the 5. usual reciprocatively operated thread guide 1930. Serial No. 444,052.
rods, and 6 the adjustable abutment members or dogs thereon which ordinarily strike against stops provided to determinedly limit the movements of the rods.
In order that the distance of traverse of any number of. rods 5 may be selectively controlled in accordance with a desired ornamentaleflfect, I provide similar, opposed and automatically movable rod stop units 7 and 7a, each consisting of a mounting 8 which carries relatively spaced groups of selectively operable rod stop slide members 9, properly positioned to cooperate with the rods 5.
There are as many rod stop members 9 in each group as there are yarn guide rods '5, and each is aligned with a respective rod, and capable of coacting with its dogs 6, mounted thereon. The members 9 are alike, and contactingly arranged in a guide slot 10 provided therefor in the mounting 8, and are provided with a manipulating handle 11, as well as V-shaped grooves or notches 12, that coact with a spring pressedball 13 in mounting 8, to hold the slides either in active or inactive position; movement limiting pins 15 in their upper ends preventing the slides from being shifted beyond proper rod stop position. A plate 14 is screwed to the front of each unit 8, to retain the slides 9 in their guide slots 10.
The units 7 and 7a are adapted to be cooperatively and automatically moved toward and from each other by suitable pattern controlled mechanism such as heretofore emplcyed for similarpurposes. I ne such arrangement is indicated in the drawings and consists of nuts 16 and 16a, to
which the units 7 and7 a are bolted, as shown,
and which are mounted and guided for axial movement on a common reversely threaded spindle 17, selectively turned step-by-step in either direction by oppositely working pawling devices which act on ratchet wheels 18 and 19, and which are actuated by pattern chain controlled mechanism generally indicated at 20.
As clearly shown in Fig. 4, when a respective stop member 9 is moved downwardly until its movement limiting pin 15 strikes against mounting 8, and the spring pressed ball 13 enters its upper notch or groove 12, the lower end of the slide is imposition to stop the respectively aligned dog or dogs 6, and consequently the guide rod 5 on which they are mounted.
Four such stop members 9 are provided for each yarn guide rod, two on each unit, and they are so mounted that the dogs 6 may 00- operate with and abutagainst either side of any one of these. A practically unlimited combination of possible stop arrangements is thereby provided and may be selected from, involving one or more stops from any unit.
It will readily be understood that the mountings 8 may be provided with more than two groups of stop members 9, in order to increase the number of variable adjustments, and that these canbe variously arranged. Furthermore, instead of slide members, levers, or other equivalent mechanical 7 expedients may be employed. The invention is, therefor, not limited'to the precise construction shown, but is capable of such changes and alterations as fairly come within the scope of the appended claims, consid ered in connection with the prior art.
I claim:
1. In a straight knitting machine having reciprocatively operated thread guide rods, a movable rod stop unit having mounted therein separate relatively spaced groups of rodstop members, individually movable to operative position.
2. In a straight knitting machine having reciprocatively operated thread guide rods, movable rod stop units each having mounted therein separate relatively spaced groups of rod stop members, individually movable to operative position and means for cooperatively moving said units.
3. In a straight knitting machine having reciprocatively operated thread guide rods, a plurality of aligned rod stop units each having mounted therein separate relatively spaced groups of selectively operable rod stop members, and means for moving said units toward and from each other.
4. In a straight knitting machine having reciprocatively operated thread guide rods, a plurality of aligned rod stop units each having mounted therein separate relatively spaced groups of rod stop slides, a'reversely threaded spindle for moving the units to ward and from each other, and pattern controlled means for turning said spindle.
5. In a straight knitting machine having reciprocatively operated thread guide rods, two aligned rod stop units each having mounted therein separate relatively spaced groups of rod stop slides, spring pressed means for determinedly holding each slide in adjusted active or inactive position in its mounting, a .reversely threaded spindle for moving the units toward and from each other,
