3 Claims.
This invention relates to thread. boards for spinning frames, and it aims to devise a rhechanism of this character which will be exceptionally simple in construction, economical to manufacture, cnvenient to use, and of such a nature that it will remain substantially free from accumulations of lint and fly and will therefore rarely, if ever, require cleaning.
The nature of the invention will be readily understood from the following description when read in connection with the accompanying draw ings, and the novel features will be particularly pointed out in the appended claims.
In the drawings,
Fig. 1 is a side elevation of the end portion of a spinning frame equipped with a thread board embodying this invention;
Fig. 2 is a front view of a small section of the thread board;
Fig. 3 is a sectional elevation of the parts shown in Fig. 2; and
Figs. 4 and 5 are sectional views taken approximately on the lines 44, Fig. 2, and 5-5, Fig. 3, respectively.
Referring first to Fig. 1, the construction there shown is chiefly an end section of a spinning frame of the type disclosed in my Patent No. 2,295,935. This latter machine comprises a series of sectional units secured end to end, each unit being substantially a complete spinning ma-' chine, except for the driving mechanism and each section includes two lines of spindles mounted at opposite sides of the frame, one of these lines of spindles being illustrated at 2 in Fig. 1. As usual, each spindle is adapted to support a bobbin, and all of the spindles are driven by bands, tapes, or in any other convenient manner, from a central cylinder. Also cooperating with the respective spindles are the usual rings mounted on a ring rail 4 and a thread board which, however, is of a unique construction and embodies features of this invention.
As is well understood by those skilled in this art, a thread board comprises a series of lappets, each equipped with a thread guide, and its function is to guide the strands drawn from the supply bobbins positioned overhead into axial relationship to the respective spindles. Each lappet should be so mounted that it can be swung upwardly and backwardly into an inoperative position, when desired for any reason as, for example, in piecing up, and such a movement should not disturb any of the other lappets. It is also desirable to make some provision for swinging all of the lappets upward and backward simultane- 2 ously preparatory to the dofling operation, and to return the lappets again to their orlgmal positions simultaneously when domng has been completed. The present invention provides in a very simple fashionfor accomplishing these results.
In the particular construction shown in the drawings, the thread board is made in sections individual to the respective sections of the spinning frame. Each thread board section coniprises a bar 5 of circular cross-sectional form supporting a series of lappets. Each of the lappets also is of 'novel form and includes a. thread guide 43 which may conveniently be made of wire twisted at one end to form the usual pig-tail eye. The shank of this guide extends slidably through a hole formed to receive it in a bushing or collar 44 and it is locked in its adjusted position therein by a set screw 45. A sleeve 46 encircling the rod or bar 5 and locked thereon by a set screw 41, supports the collar 44 for rotative movement around the bar, and the collar is slotted throughout a portion of its circumferential extent to receive the set screw 41.
With this arrangement the adjustability of the sleeve 46 around the bar 5 facilitates the setting of all the lappets in a common horizontal plane. The thread guide 43 is adjustable lengthwise of itself so that its eye may be positioned directly in line with the spindle, and since the eccentric collar 44 has a limited rotative movement around the sleeve 46, it permits the operator to tip the thread guide up out of the way when she is piecing up, this tipping movement being limited by the set screw 41 and the length of the slot. In Fi 4 the set screw 41 bears against one end of the slot and prevents further downward movement of the guide 43. The other end of the slot is shown at 48.
In order to support the bars 5 of the thread boards of adjoining spinning frame sections, and
also to provide for the simultaneous movement of all of the lappets from their operative to their inoperative posltions, and vice versa, in connection with the domng operation, upright bars or posts 50, Fig. 1, are provided between sections and at the outer ends of the end sections. A two-part clamp 5| is clamped on each post 50 by a screw 52, Figs. 3 and 4, and its parts are shaped to receive and to provide bearings for the adjoining end portions of the two bars 55 of said sections, as shown in Fig. 4. A disk 53 having diametral tangs or tongues a and b, integral therewith and projecting at right angles to each other from opposite faces of said disk, enter grooves provided to receive them in the two adjacent end faces of This application is a division of my copending application Ser. No. 402,581, filed July 16, 1941.
Having thus described my invention, what I desire to claim as new is:
1. In a spinning frame, a thread board comprising a horizontal bar of circular section, a
' series of lappets mounted on said bar, each of said economical to manufacture, in which the parts overlying the spindles occupy surprisingly little space, are capable of quick and accurate adjustment into the proper relationship to the respective spindles, are freely movable individually when desired, and can all be readily swung simultaneously out or and back into their operative positions in connection with the dofllng operation. At the same time this construction presents a minimum of surface on which lint or fly can accumulate. It will be observed that practically all the surfaces on which fly can settle are so shaped that the particles slide of! them, and this is particularly true if the surfaces are chromium or nickel plated or are highly olished. In the par ticular construction shown, this shaping consists in rounding the upper surfaces of the various elements of the thread board. Or. these surfaces might be inclined. In fact. the rounded surfaces are'composed of inclined surface elements. Any
such construction satisfies the requirement ofshedding lint and fly.
While I have herein shown and described a preferred embodiment of my invention, it will be evident that the invention is susceptible of embodiment in other forms without departing from the spirit or scope thereof. Also, while the invention is herein disclosed as applied to a spinning machine, it is obvious that it is equally applicable to a twister, and both machines will be herein included in the term "spinning frame."
lappets comprising a collar supported on said bar foradjustment around the axis of the bar, and a thread guide having a guiding eye at its outer end and including a shank extending through a transverse hole in a part of said collar encircling said bar whereby it is adjustable in a direction transverse to said bar, and means ,for locking 'said' thread guidein different adjusted relationfor rotative movement thereon, a thread guide mounted in said collar for adjustment transversely to said bar, means for fastening said sleeve to said bar, and means limiting the rotative movement of said collar and said thread guide around the sleeve.
3. In a spinning frame, a thread board comprising a horizontal bar, a series of lappets mounted on said bar, a second bar positioned end to end in axial alignment with said first bar, lappets mounted on said second bar, an upright post, a two-part clamp embracing said post and supporting adjacent ends of said bars for rotative movement around their common axis, and means simultaneously.
