Patented. July 24, 1906.

To all whom it may cancer L.

Be it known that I, Isaac PALMER, a citizen of the United States, and a resident of Middletown, in the county of Middlesex and State of Connecticut, have invented new and useful Improvements in Thread-Guides, of which the following is a specification.

My invention relates to thread-guides, and more particularly to thread-guides adapted to be used on spinning or twisting machines where itis desirable that the eye of the guide shall be adjusted accurately over the top of the spindle. accuracy, it is important that they be ca able of adjustment both longitudinally and in a swinging directionviz., having a universal' adjustment in'a horizontal plane or plane transverse to the axis of the spindle.

In the accompanying drawings, Figure 1 represents a portion of a spinning-machine, showing two of the thread-guides in their horizontal position as in use and one of them turned up into a vertical position for purposes of adjustment or renewal or for gaining access to the spindle, as the case may be. Fig. 2 is an enlarged bottom plan view of the thread-guide, showing its attachment to the finger-board. Fig. 3 is an edge view of the same. Fig. 4 is a bottom plan of a' threadguide, showing a modified form of attachment to the finger-board. Fig. 5 is an edge view of the same, and'Fi s. 6 and? represent modified forms of thread -guide shank.

The thread-guide, Figs. 1 to 5, inclusive, is shown as consisting of a piece of wire having its shank 1 turned back along itself to form an elongated open loop 2fo1= the reception of the fastening means for securin it to the finer-b'pard 3, the opposite end 0 the said wire eing bent to form the eye 4 of the gpide, as usual. The part of the shank whic forms the loop 2 rests on a flat washer 5, applied to the under side of the finger-board 3, and is held in'the desired adjustment both longitudinally and in a swinging direction either by means of a clamping-plate 6, which isiforced down against the loop portion of .the'shank by means of a screw 7, which passes through the clamping-plate 6 and through the loop 2 and washer 5 into the finger-board 3, or by the head of the screw itself, as shown in Fig. 4.

The face of the washer or bearin'glate 5 is rovided with a lug or teat 10*, ocated eit er in advance of the holding-screw or behind it. This teat may conveniently be struck up from the body of the plate and by To adjust these eyes with great it also -sprea extending between the sides of the loop forms a bearing to hold the loop in position, while the plate or washer 5 will be held securely in place by the frictional contact between it and the board, or the bearinglate or washer may be provided with a nec 12, with a pair of lugs 13 14 at its end to embrace the shank in proximity to the doubled portion, and the screw-hole in the washer may be elongated, as shown in dotted lines, Fig. 4.

When the clamping-plate 6 is omitted, the head of the screw 7 may be enlarged, forming,

in effect, a clamp-screw 8, as shown in Figs. 4

and 5, where the head 9 of the screw is made sufficiently large to overlap the opposite parts of the loop portion of the guide, so that the simple screwing of the screwsS intothe fin ger-board 3 will serve to clamp the guide in such ad'ustment as may be desired bothin a longitu inal and swingin direction. Infact, in ordinary use this simp e screw with its en-' larged head, the washer or bearing-plate, and the thread-guide formed of a single piece of wire so disposed as to furnish an elongated loop in its shank are all that is re uired to produce aneflicient and readily-a justable thread-guide.

Not only does the turning of the end of the shank to form the elongated loop serve to provide for the ready and universal adjustment of the (guide in a horizontal plane, but

s theshank laterally to such an. extent that the guide is very easily held against any possible rollin or displacement w en in use. The shank 0% the thread-guide maybe offset, as shown in Fi 3, to bring the eyeinto the central plane of t e finger-board,

or it may be left'straight, as shown in Fi 5.

Instead of making the loop in the shank e onated it may take a circular form, as shown in igs.,6 and 7, where the loop portion of the.

shank is denoted by 10 and 1-1, respectively.

In this form the loop is made enough larger than the shank of the screw to admit of the necessary adjustment of the guide longitudi nally as well as in a swinging direction. The

loop maybe a closed one, as shown in Fig. 6,

or an open one, as shown in Fig. 7." In the latter case the guide may be removed and placed in position without removing the screw om the finger-board.

The structure is a very simple and inexshank, a bearing-plate or washer rovided with a projection on its face exten ing into the opening in the shank, and means for securing the guide'in position in the desired longitudinal and swinging adjustment.

2. A threaduide support, a thread-guide having its shan turned back along itself to form a loop, a fastening device passing through the loop and leaving the uide free to be adjusted bodily thereon in a ongitudinal and swinging direction, and a bearingplate or washer interposed between the thread-guide and its support and provided with a proj ection extending between the sides of the loop.

3. A thread-guide comprising a wire having a return-bend in its shank, a washer formin a bearingfor the shank and provided with a ug struck up from its face in position to engage the said return-bend, a clampingplate and a screw for forcing the clampingplate toward the washer to lock the guide in position. y

In testimony that I claim the foregoing as my invention I have signed my name, in pres ence of two witnesses, this 14th day of April, A. D. 1906.
