My invention relates to rings and ring travelers of the vertical type for spinning and twist ing machines.
'More particularly the present invention ap- 5 pertains to rings and travelers wherein a constituent part of the traveler. head includes a downwardly and rearwardlydlrected nose disposed to prevent accidental disengagement of the, thread from the head, and to maintain the 10 traveler shank in contact with the inner face of the ring. Such a constructiony is disclosed in Letters Patent of the United States No. 1,880,084 issued to me Sept. 27, 1932, and on which the present invention is an improvement.
In this type of traveler the free endI of the nose is, in running position, in contact with or closely adjacent to the outer face of they-ring, and, in threading position, the nose is so slightly interspaced from the latter that the insertion of the delicate thread or filament into the traveler head through the vrestricted space between the nose end and ring prior to starting the spindle, or in other words piecing up the end," has a tendency to split, separate, or abrade the filament. y
Essential objects of my invention are, while retaining the advantages inherent in a traveler nose disposed downwardly and inwardly towards the outer face `of the ring, to avoid injury to the lament during the threading operation; to facilitate the introduction of the filament into a ring traveler head; to prevent accidental escape of the same therefrom; and to attain these results in a simple, strong, and inexpensive structure adapted for operation upon internally recessed or non recessed rings.
To the above ends primarily my invention consists in such. parts and in such combinations of parts as fall within the scope of the appended claim.
In the accompanying drawing,
Figure 1 is a perspective diametrical section of a spinning or twisting ring carrying my novel traveler in running position thereon,
Figure 2, a fragmentary plane section oi the ring showing'the traveler in threading position,
Figure 3, a perspective view of the traveler,
Figure 4, a fragmentary plane section of a nonrecessed ring showing a modified form of traveler mounted thereon in threading position, and
Figure 5, a side elevation-of a second modied form ,ofy my novel traveler.
Like reference characters indicate like4 parts throughout the views.
As herein illustrated I2 represents a spinning or twisting ring of the vertical type, seated in the usual ring rail I3 of a spinning or twister frame.
My novel traveler of the vertical type I is formed from a wire or rod of any desired or preferred cross sectional contour. It comprises 8 an elongated shank I8, a foot Il ,upon its lower end, and a head I8 connected to the upper end of the shank by a bend I9. 'I'he head includes a base portion 20 extending rearwardly and upwardly from the bend, thence a forwardly extending top lportion 2|, and lthena nose portion 22 extending downwardly and rearwardly towards the traveler shank and toward the outer face of the ri'ng as well as in substantial alignment with the bend I5, and in the vertical plane of the remainder of the traveler. Integral with the free end of the nose portion is an open loop 24 whose convex intermediate or bearing portion 25 is directed towards the ring, and its free end portion 28 is directed upwardly and forwardly. 20
The bearing portion 25 is spaced from the upper portion of the shank I6 preferably approximately the width of the thickness of the ring when intended primarily'for lubricant spreading purposes, butwhen the desired function of the traveler is solely the retention of the filament from accidental escape from thetraveler head the space between the shank and bearing portion may if desired be greater than that indicated.
The ring I2 is provided with one or more, in this instance two, lubricating recesses or grooves 28. Such grooves are shown in Figures l and 2. These grooves may, if desired, be omitted, as shown in. Figure 4, if the lubricant has been initially manually applied to theinner surface of the ring, or if the sole desired purpose is the prevention of accidental escape of the thread or filament from the traveler head.
The form of traveler head may be changed to accommodate different diameters of the bers to be twisted provided that the nose portion be inwardly and downwardly directed and its described terminal loop or its equivalent be present.
A modified form of my novel traveler is shown in Figure 4 and includes an open loop 30 from whose bearing portion 3i its free end 32 is di.- rected forwardly and upwardly upon the side of the nose opposite to that of the end portion 26 of the loop 24.- In the modification shown in Figure 5 the bearing member consists of a closed 50 loop 33 wherein the loop'end 35 overlaps the nose.
To perform the threading operation the 'spindle is stopped, which releases the tension on the a slack vertical position hanging loosely by its head from the upper edge of the ring. with its foot Il depending slightly below the lower edge thereof. The traveler is next manually elevated lifting the loop 24 out of contact with the -ring aiordln'g, as shown in Figure 2, a space or channel Il for the insertion oi the illament 36. held horizontally, therethrough into the interior'oi the head as at 3B, and the travelerl allowed to drop into depending position. When the spindle is restarted the traveler and filament resume their original running positions. In Figure 2 the filament is shown about to be inserted.
In running position the contact of the loop with the ring prevents accidental escape of the lament from-the ring, but escape occasionally.
occurs while the spindle is inactive and the ring rail is continuing its traverse action with thev traveler in slack position. Under these conditions, the torsional energy stored in the filament creates one or more tightly twisted stiff loops which sometimes elevate the traveler, and the unlooped portion of the iilament crawls from its position shown in Figure l along the top oi 'across the bottom edge of the ring, and a head including an inwardly and upwardly and then outwardly directed top portion adapted to engage with the top edge of the ring, an inwardly and downwardly directed nose portion upon the outward end of the top portion, and a loop 4comprising a convex bearing portion formed by bending Iinwardly and upwardly said nose portion, said loop engageable with the outer ring face when the traveler is in running position and terminating in a free end portion nextending E0 upwardly and outwardly and lying between said nose portion and the outer face of the ring. v
