YARN-GUIDE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 433,037, dated July 29, 1890.

Application filed October 19, 1889. Serial No. 327,533. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN S. RICHARDSON, a citizen. of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Yarn- Guidcs for Spinning-Machines, of which the following is a'specification.

My invention relates to yarn-guides for spinning-machines; and it consists in the devices and combinations hereinafter described and claimed, the object of which is to dispense with the finger-board heretofore commonly used, and by making the yarn-guide in two parts hinged to each other, to attach the same directly to the thread-board In the accompanying drawings, Figure 1 is a transverse vertical section of a part of a ring-spinning frame, showing a part of the frame proper, drawing-rolls and their stand, the thread-board and its supporting-rail, and my improved yarn guide secured to said thread-board, and part of a spindle; Fig. 2, an isometric perspective view of a part of the thread-board, the rail to which it is hinged, and two yarn-guides of my improved construction, one of which is in its normal position and the other of which is turned back out of position; Fig. 3, a vertical transverse section of a part of the thread-board, the rail to which it is hinged, and my improved yarn-guide secured thereto, said guide being shown in full lines in its normal position and in dotted lines turned back out of position; Fig. 4:, an isometric view of adjacent portions of the attaching and movable parts of my improved yarn-guide; Fig. 5, a vertical cross section of the yarn-guide on the line 5 5 in Fig. 3; Fig. 6, a similar section, showing a hollow rivet in place of the solid rivet and washer shown in Fig. 5.

The frame A, spindle B, roll-stand C, drawing-rolls c, and rail D are all of the usual con struction and operation,allof these parts being duplicated at the opposite side of the machine, except the frame, which is alike on both sides. The yarn passes from spools (not shown) supported above the frame through the drawingrolls 0, thence through a yarn-guide and through atraveler on a spinning-ring to a bobbin or cop-tube on the spindle in the usual manner. The thread-board E is of the usual construction and extends throughout the length of the whole row of spindles, being hinged to the rail D at e.

The yarn-guide, as usually constructed, is a stout wire screw-threaded at. one end and at the other end bent into an eye, which from its shape is sometimes called a pig-tail, and this wire is not attached directly to the threadboard, but to a short finger-board hinged to the thread-board, there being as many fingerboards as there are guides, so that any guide may be thrown out of position by moving its finger-board, and all of the thread-guides at one side of the spinning-frame may be raised out of position by raising the thread-board.

These finger-boards are somewhat expensive, each being commonly attached to the thread board by an inch-and-a-half butt and six screws, the butt and the screws being com;

monly of brass, and the finger-board and the butt requiring to be of considerable length to prevent a lateral movement of the yarn-guide or pig-tail. The finger-boards also present a considerable surface for the accumulation of lint.

I dispense entirely with the finger-board, forming the yarn-guide F in two parts, the attaching part f of which is a screwcye, and the other or movable part f of which is provided at f with a yarn'eye of any usual form, and is also provided with another eye f by means of which and by means of a rivet f it is attached to the eye f of the attaching part f. The eye f of the attaching part of the yarnguide is above the straight shank f of said attaching part, said shank being screwthreaded and tangent to said eye f as shown in Fig. 4. The shank is screwed into the edge of the thread-board parallel with the top of said board, so as to bein ahorizontal position when the thread-board is in its normal position.

The movable part f of the yarn-guide is provided at itsinnerend with aloop f which is more than half a circle, and is between said loop and the end thereof bent laterally at right angles to the general direction of said part f below the part f to form a stop f which, as the movable part of the yarn-guide is moved to its normal position, prevents said movable part from descending below a hori zontal position by striking against the under side of the attaching part. The eye f is slightly smaller than the eye f in order that when the attaching part f is screwed into the thread-board until the eye f comes in contact with said thread-board the eye f may be out of contact with said thread-board, and by friction thereon may not interfere with the movement of the part f of said-guide.

The'shape of the attaching part of the guide causes the stop f to press with considerable friction against the under side thereof when "the movable part is in its horizontal position and prevents said movable part from being raised by the jar of the machine, and also assists in preventing a lateral motion of said movable part. Instead of the rivet j, which is'provided at one end with a head f and at the other end passes through a washer f outside of which said rivet is headed in the usual manner, a hollow rivet f or eyelet may be used. In either case if the joint between two parts of the guide becomes loose through wear it may be tightened by unscrewing the guide from the thread-board and slightly hammering the rivet endwise.

To prevent the attaching part from being screwed into the thread-board far enough to cause the eye f to mar the thread-board or to enter the surface of the same so far as to bring the eye f against the thread-board, and thereby to hinder the movement of the movable part of the guide by increasing its friction on the board, a washer f maybe placed around the shank of the attaching part between the eye f and the thread-board; but

this is unnecessary it reasonable care be used. The guide above described is much cheaper than the finger-board and guide generally used, does not catch the lint and flying, is less liable to get broken, and can be attached or replaced at much less expense.

I claim as my inventionl. A yarn-guide formed in two parts hinged to each other, one of said parts having a yarneye and the other of said parts having a screwthreaded shank, as and for the purpose specified.

2. A yarn-guide having an attaching part provided with an eye and a screw-threaded shank, a movable part provided with a yarneye or pig-tail and with anothereye or loop, and a rivet passing through said last-named eye or loop and the eye of said attaching part and hinging said attaching part and said movable part to each other, as and for the purpose specified.

3. The combination of the attaching part having an eye and a screwthreaded shank tangent to said eye, the movable part having JOHN S. RICHARDSON.
