RING SPINNING OR TWISTING MACHINE.
Application filed April 30, 1913.
To all whom it may concern.
Be it known that I, ALoNzo E. RHoADEs, a citizen of the United States, residing at Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Ring Spinning or Twisting Machines, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.
This invention relates to ring spinning or twisting machines and it has more particu lar reference to the means for guiding the ring-rail in its reciprocation due to the builder-motion, such reciprocation of the ring-rail acting to lay the yarn with the proper traverse upon the rotating yarn receivers or bobbins carried by the usual spindles.
In apparatus of this type the means usually employed for guiding the ring-rail in its reciprocating movement is defective in that there is a tendency for the rail to chatter or vibrate more or less, particularly near the upper end of its stroke, such vibration having an objectionable effect upon the yarn. So, too, there is some tendency of the ringrail, because of this vibration, to become twisted or deflected out of true. These objectionable features have been overcome previous to my present invention but the de vices employed were of such a character as to prevent the ready removal of the ringrail from the machine. Such a guiding device for the ring-rail is shown, for example, in my Patent No. 990,501. The ready removal of the ring-rail is a matter of considerable importance due to the tendency of the rings carried thereby to become clogged by foreign matter or befouled by dirt during the operation of the machine and to the fact that the complete cleansing of these parts is extremely difiicult if not impossible while the ring-rail is in position upon the machine.
My present invention has for its object the production of novel means which will be as eificient for guiding and preventing twisting or improper vibration of the ring rail as the device shown in my prior patent referred to, and which will at the same time permit the ready removal of the ring-rail Specification of Letters Patent.
Patented Dec. 22, 1914. Serial No. 764,483.
for the purpose of cleaning the rings therei Figure 1 is a vertical sectional view, with certain parts shown in elevation, of a portion of a twister embodying one form of my present invention, the section being taken through that portion of the, machine carrying the ring-rail and its cooperating parts immediately engaged in the twisting of the yarns and their winding upon the. bobbin. Fig. 2 is a plan view upon a reduced scale of the ring-rail, with the rings and the guiding means carried thereby. Fig. 3 is a View in cross-section along the lines 33 of Fig. 2, of that portion of the ring-rail atwhich the power is transmitted from the buildermotion to the ring-rail, a portion of the lifter rod of this builder-motion being shown in elevation.
It is to be understood that the views represented in the figures of the drawing are taken from one side portion only of the machine. A description of these parts, however, is sufiicient since they are duplicates of the other side portion of the machine.
Referring to the drawing in detail, the fixed side rail 1 in which the twisting spindles 2, only one of which is here shown, are rotatably mounted, the vertically-reciprocating ring-rail 3, having suitable rings 4, the delivery rolls 5 mounted in the stand 6, on the top-board 7, the guide wire 8, the whirl 9 imparting rotary movement to each spindle and driven by the usual spindle-driving drum, not shown, the lifter rod 10 through which a vertical-reciprocatory motion is imparted to the ring-rail may be and are all of the usual construction, and as shown in my prior patent referred to. In my present invention I have, however, departed from all prior constructions in the guiding device for the vertically reciprocating ring-rail and in the addition thereto of means for permitting the ready removal of the ring-rail, and I will now point out these structures in detai Between two supporting members 11. and 12, Fig. 1, the first rigidly attached in the manner shown, or in any desired manner, to the top-board 7, and the second similarly attached to the spindle rail 1, there is placed a guide rod 13, secured to the upper supporting member 11 by means of the integral head 14 and the bolt 15, and adjustable to vertical position in the lower supporting member 12 by set screw 16.
Attached to the under side of the ringrail and conforming in contour therewith are guide brackets 17, each having an angular extension 18 clearing the flange of the ring-rail and partially surrounding by a hook-shaped portion 19, the guide rod 13. By reason of the central portion 17 of the guide bracket conforming in contour to the flanged under side of the ring-rail and by the addition thereto of the groove 20 in the angular extension 18 into which the flange of the ring-rail adjacent the guide-rod fits, a structure of great rigidity is provided when the guide bracket is attached to the ring-rail by the bolts 21, and this rigidity of structure is of considerable importance as will soon appear.
The hook-shaped portion 19 of the guidebracket is made with the mouth of the hook extending in a line parallel with the ringrail, and the diameter of the hook transversely of the ring-rail is such as to provide a close sliding fit upon the guide rod 13. The mouth of the hook is so extended that there is provided a bearing of some extent longitudinally of the ring-rail and in the direction in which the ring-rail with the guide-bracket thereon must be moved to free the hook-shaped portion from the guide rod, the purpose of this extended bearing being to prevent any displacement of the guide-bracket from the guide rod due to any possible longitudinal movement of the ringrail in the operation of the machine. While of course any number of these parts desired may be provided, it has been found in practice that two of these fixed guide rods 13 arranged in parallelism with the ring-rails 3 as shown in Fig. 2, and two guide brackets 17 upon the ring-rail with hook-shaped portions 19 embracing the guide rods, are sufficient to provide an efiicient guiding means for the ring-rail in the operation of the machine.
The removal of the ring-rail is readily accomplished after the withdrawal of the bobbins from their spindles, by a movement of the ring-rail in the direction of its length, and opposite to the direction in which. the hook-shaped portions 19 open, until these hook-shaped portions of the guide-brackets have cleared the guides 13, whereupon the ring-rail to be freed from the machine is elevated over the tops of the spindles and laterally withdrawn.
Tt is, therefore, particularly to be observed that the hook-shaped portions 19 of the guide brackets 17 not only form a slidable bearing upon the fixed guide rod 13, but that the extended lips of this portion of the bracket forming the opening or mouth of the hook perform a function entirely independent of that of guiding the ring rail in its vertical reciprocatory movement, that of at removing means for the guide-bracket and attached ring-rail, such means being operated simply by a manual movement of the ring-rail in the manner already stated.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
In an apparatus of the class described, a ring-rail adapted to be vertically reciprocated by the builder-motion, a plurality of fixed vertical guides located adjacent said ringrail, a plurality of guide-brackets attached to said ring-rail and ending in book shaped portions embracing said fixed guides to insure a smooth even traverse of the ring-rail, said hook-shaped portions extend.- ing in a horizontal plane and opening in the same direction whereby by an endwise movement of the ring-rail it may be freed from said guides and removed for cleaning or repairs.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
