GUIDE-BOARD FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 325,307, dated September 1, 1885.

Application filed January $1, 1885. (No inodcLl 1"0 all whom it may concern:

Be it known that I, J OHN BARKER, of Lawrence, county of Essex, State of Massachusetts, have invented an Improvement in Guide-l3oards for Spinning-Frames, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to improve the construction of guide-boards, whereby they are made more durable, and whereby the friction on the yarn is reduced to the minillllllll.

Guideboards as now commonly used are provided with eyelets, some of which are slotted and made of bone or porcelain inserted in holes made through the boards vertically, the eyelets being held in place by cement.

In accordance with my invention the guidehoard slotted at its edge inward for the en trance of the yarn being spun is provided with pockets or recesses cut into the same from its top side to receive small cylinders of glass or equivalent vitreous material, and the upper side of thesaid board, instead of being left exposed, as previously, being protected by a steel or metal plate, also slotted inward from one edge to correspond with the slots in the guide-board, the said metal plate serving the purpose of not only holding the glass wearing-surfaces in place, but also covering and protecting the top of the guideboard, the slotted plate preventing wear or injury to the board in the said slots either by wear or by blows.

Figure 1 represents a sufficient portion of a spinning-frame to show the position of the guide-board with relation to thespindles and rolls. Fig. 2, on a larger scale, represents a guide-board provided with my invention, the metal covering-plate being broken out opposite one of the slots to represent the glass cylinder, which is used as the wearing surface or support for the yarn. Fig. 3 is a section of Fig. 2 in the dotted line a: as.

The framework A, bolster-rail B, liftingrail 0, the spindle D, flier E, spool F, rollerstand G, rolls H and I, and rail L are all in common spinning-frames, so need not be herein described. I have shown such old and common devices in order to illustrate the position of the hinged guide-board a, which it is the object of this invention to improve.

The guide-board a is slotted at its front edge, as at Z), and is bored through, as atb, to constitute a slit and eye for the reception of the yarn c which is being spun. The upper side of the guide-board is provided with a recess, (2, which intersects the eye I), and 111 this recess is placed the cylindrical piece 6, of glass or other vitreous material, that portion of the surface of the piece of glass referred to which intersects and crosses the line of 1) serving as a rest or support against which the yarn bears and over which it is drawn as it is spun and wound up in the usual manner. The upper side of the guide-board is provided with a steel or hard-metal plate, connected therewith by screws f, and the said metal plate is slotted from its front side inward, as at g, is rounded, as at g, and at the inner end of said slot 1 have provided an eye, 9 the inner rearwall of which in the dotted line so is located back of a vertical line drawn to intersect the front edge of the glass support or guide 6. o

The guide or support 6 is so located with relation to the upper end of the spindle and the rolls H I that the yarn is kept from contact with the metal plate f at the inner end of the notch therein, thus preventing the same from cutting or fraying the yarn.

The metal plate f protects the wooden part of the guide-board, which is slotted for the reception of the yarn, and any roughness of the board is not felt by the yarn, nor is the board in the slots liable to be injured or roughened by blows, as when not protected by the plate. The plate f also acts to retain in place and cover the support or guide 6.

Instead of the flier E, I may use an ordinary cap without departing from my invention.

I claim- 1. The guide-board slotted at b b and recessed longitudinally at d, combined with the cylindrical supports or guides c, of vitreous material, placed in the said recesses, substantially as described.

2. The guide-board slotted at b b and re- In testimony.whereoflhavesigned my name cessed at d, and the vitreous supports or rests to this specification in the presence of two sub- [0 '0, laid in the said recesses and crossing the scribing witnesses.

all substantially as set forth.
