KNITTING MACHINE.

Application filed January 12,1922.

T0 aZZ whom it may concern:

Be it known that I, JOSEPH S. PECKER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Knitting Machines, of which the following is a specification.

The invention relates to a double rib knitting machine of the kind known as edgers on which pattern work such as embroidery used for trimming underwear, curtains and various patterns of neckties can be made.

The object of the present invention is to provide a simple, practical and comparatively inexpensive construction which will be strong and durable and adapted for winding up the finished fabric and of maintaining a proper tension thereon.

A further object of the invention is to provide mechanism of this character capable of aejustment to Vary the speed of the wind ing rolls to adapt them to the output of the knitting machine to which the mechanism is applied and arranged in a position which will afford a ready inspection of the finished material by the operator.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construc tion, within the scope of the claims, may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings in which like characters of reference designate corresponding parts in the several views Figure 1 is an end elevation of a knitting machine embodying my invention, parts being omitted and other parts being in section.

Figure 2 is a front elevation of the same, parts being in section and other parts being broken away.

Figure 3 is a plan View partly in section.

Figure 4 is a horizontal sectional view illustrating the construction for limiting the movement of the ratchet mechanism.

In the accompanying drawing, in which is illustrated the preferred embodiment of the invention, the means for making the va- Scrial No. 528,774.

riouspatterns of edging and the various working parts of the knitting machine are omitted as the same do not constitute a portion of the present invention. The frame of the machine comprises standards 1 tied to gether by horizontal connecting bars or braces 2 and mounted on the braces 2 are vertically arranged brackets 2-3, having vertical openings 3 in which are mounted vertically slidable bearings l. The bearings -l have journaled in them rolls 5 which are geared together at each end by means of spur gears 6 and one of the rolls has an extended journal on which is mounted an auxiliary gear 7, as clearly illustrated in Fig ure 2 of the drawing. The slidable bearings a are yieldably maintained in engagement with. the knitted mate-rial by coiled springs 3" and the tension of the latter is adjusted by screws P mounted in the bearing brackets at the top thereof and equipped with lock nuts 49.

Mounted on the exterior of the frame of the machine is a vertical bracket 8 pivoted at its lower end by a bolt 9 or other suitable pivot and adjustably held in position by means of a bolt 10 passing through the upper portion 11 of the bracket and operating in an elongated arcuate slot 12 which permits a pivotal adjustment of the bracket on an are described from the center or pivot 9 of the said bracket. The slot 12is formed in the enlargement of the upper portion of the bracket whiclrextends laterally from opposite sides of the body portion of the bracket, as clearly illustrated in Figure 1 of the drawing.

The pivoted bracket is provided with lower and upper bosses 13 and la: and journaled in the lower bosses 13 is a horizontal shaft 15 on which is mounted a gear 16 and a ratchet wheel 17. The gear wheel 16 and the ratchet wheel 17 are secured to the shaft 15 by means of keys 21 and 22 and the gear 16, which is arranged at the inner end of the shaft 15 meshes with the auxiliary gear 7 of the rolls and is adapted to impart motion to the same and the said shaft 15 is provided at its inner end with a nut 15 or other suitable fastening means for detachably securing the pinion 16 to the said shaft 15. The pinion 16 is adapted to be removed from the shaft for the purpose of permitting a pinion or gear of a different diameter to be arranged on the shaft for driving the rolls 5 at the proper speed to correspond with the output of the knitting machine so that the feeding mechanism for actuating the rolls hereinafter describi al, will rotate the rolls at the proper speed to maintain the desired tension on the knitted material.

The boss 13 is provided with a reduced portion 13 on which is mounted an adjustable arm 19, approximately L-shaped, as clearly shown in Figure l, and extending radially with respect to the ratchet wheel and havingits upper terminal portion eX- teuding across the periphery of the ratchet wheel, The adjustable arm 19 is secured in its adjustment by means of a clamping screw 20 mounted on the hub portion of the arm 19 and engaging the reduced portion 13. The ratchet wheel 17 and the gear 16 turn as one on the shaft 15, due to the said keys 21 and 22, so that motion is communicated to the rolls 5 when the ratchetwheel is rotated.

The outer end of the shaft 15 forms a pivot for a rocker arm or lever 18 pivoted to the upper end of an inclined reciprocatory rod 30 which forms a longitudinal extension of and is carried by a slide or member 27 actuated by-a cam 26 engaging at its upper side a roll 28 of the said slide. The adjustable arm 19 limits the downward movement of the rocker arm or lever 18 and thereby controls the length of the step by step movement of the ratchet wheel. The rotation of the cam imparts a rise and fall motion to the slide 27 and the rod 30, which constitutes a reciprocatory member for operating an actuating pawl 32 to impart to the ratchet wheel a step by step rotary movement. The cam 26 is mounted on a cam shaft 25 which is journaled in a suitable bearing 24 supported by an extension 23 of the frame of the machine. The slide or lower section of the reoiprocatory member is provided with a longitudinal opening 27 and through which passes the cam shaft and the upper end of the slide or section 27 is provided with a suitable socket 27" in which the lower end of the rod 30 of the reciproeatery member is mounted. The rod is preferably square in cross section but any other suitable form of rod may, of course, be employed and the lower end of the rod may be secured to the slide in any other desired manner. The roll 28 rests upon the cam 26 at the top thereof and is maintained in con tact with the same by means of a coiled tension spring 29 arranged at an inclination and suitably anchored at its lower end and connected at its upper end to the lower terminal of the reciprocatory member. The actuating pawl which engages the teeth of the ratchel wheel 17 is maintained in engagement with the said teeth by a coiled spring 32 connected at one end to the rod or section 30 of the reciprocatory member construction the ratchet wheel 17 is posi-- tively actuated by pawl in the upward movement of: the reciprocatory member and is adapted to ratchet over the teeth of the ratchet wheel in the downward movement of th reciprocatory member. The upper end of the reciprocatory member is pivoted to the rocker arm or lever 18 by means of a suitable pivot or pin 83 and the said rocker arm or lever 18 causes the upper end of the reciprocatory member to travel at a tangent to the ratchet wheel 17. The ratchet wheel 17 is held against retrograde rotation by means of check pawl. 3 1- pivoted at its upper end at 53 i and provided at its lower end with an engaging portion 34 The engaging portion ofthe check pawl is maintained in en 'ageinent with the teeth of the ratchet wheel by means of a coiled spring 35 connected with the pawl 34: and with the frame of the machine. The pawl 9.41 is located above and beyond the throw of the reciprocatory member and is disposed at an inclination, as clearly shown in Figure 1 of the drawing. When the reciprocatory member moves upwardly the ratchet wheel is partially rotated and the winding rolls 5 are correspondingly rotated and in' the downward movement of the reciprocatory member the ratchet wheel and the rolls are held against movement by the check pawl 34. The winding rolls are mounted at the front of the machine so that the material passing around and between the rolls will be fully exposed to the inspection of the operator of the machine.
