`Specification of Letters Patent.

Application filed May 8, 1905. Serial No. 259,324.

To LZZ whom, t may concern,.-

Be it known that I, HERBERT F. PALMER, a citizen of the United States, residing at Lewiston, in the county of Androscoggin and State of Maine, have invented new and useful Improvements in Collar-Boards for Mules in Spinning Machinery, of which the following is a specification.

This invention relates to an improved collar-board for mules in spinning machinery.

The object of the invention is to provide a collar-board in which the bearings for the spindles are adapted to be readily and conveniently removed and new bearings inserted or reversed in position, so that what formerly constituted the back of the bearing may be replaced by the front thereof, and vice versa, the wear upon the back of the bearingbeinggreater than upon the front on account of the pull of the yarn upon the spindle in that direction and also on account of the pull of the belt upon the pulley fast to the spindle and by which it is rotated being in the same direction-wiz. ,toward the back ofthe collar-board.

The invention consists in thecombination and arrangement of parts set forth in the following` specification and particularly pointed out in the claims thereof.

Referring' to the drawings, Figure 1 is a vertical transverse section, partly in elevation, of my improved collar-board, illustrating a spindle and bobbin in connection therewith, said spindle and bobbin being broken away to save space in the drawings. Fig. 2 is a section, partly in elevation, taken on line 2 2 of Fig. 1.

Like numerals refer to like parts throughout both views of the drawings.

1n the drawings, 5 is a collar-board constructed in accordance with my invention and consisting of two parts--a front 6 and a cap .7. The front 6 and cap 7 extend longitudinally side by side and are each preferably made in two parts, the front 6 being made of a wooden strip 8, to which is fastened a metal strip or lining 9, while the cap 7 is preferably made of a wooden strip 10, having a metal lining 11 fast thereto. The metal linings 9 and 11 are fast to the wooden strips 8 and 10, respectively, by screws 12 12.

The metal lining 9 is provided with a fiange 13, extending longitudinally along the top thereof, and also with a flange 14, extending' longitudinally along the bottom thereof. The metal lining 11 is provided with flanges 15 and 16, extending longitudinally along the top and bottom, respectively, thereof. The flanges 13 and 15 and 14 and 16 are provided at intervals with semicircular recesses 17 17, through which the spindle 18 projects, said semicircular recesses being of sutlicient diameter to allow a slight clearance between said spindle and said flanges.

A series of boxes 19 is provided which form bearings for the spindles 18. said boxes being each made in two parts 20 and 21. Said boxes are located between the top tlanges 13 and 15 and the bottom iianges 14 and 16 of the metal linings 9 and 11, respectively. Each of said boxes 19 is provided with an oil-chamber 22, to which oil is supplied through an oil-passage 23. leading downwardly from the top ot' said box.

The cap 7 is held to the front 6 by means of bolts 24, said bolts serving to clamp the two parts 20 and 21 of the boxes 19 against each other and between the cap 7 and `front 6, so that said boxes are iirmly held in position and the two parts of the collar-board are also firmly fastened one to the other. It will be noted that there is a space left between the top iianges 13 and 15 and between the bottom fianges 14 and 16. This is to allow for adjustment, so that when the bearing-boxes become worn by continual use the adjacent faces of the two parts of which said boxes are formed may be slightly filed oi, thus reducing the diameter of the bearingl of the box so as to more closely iit the spindle.

It is evident that by removing the bolts 24 the different boxes may be removed and reversed to provide for wear thereon or that any one of said boxes may be removed and a new box inserted in its place with very little trouble by unscrewing the nuts from the ends of the bolts 24 and removing the cap 7 of the collar-board.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, 1sW

1. A collar-board in two parts consisting of a front and a cap, said front and cap each having a metal lining extending longitudinally thereof and adjacent to each other, and a series of spindlebearing boxes in two parts clamping together between said front and cap.

2. A collar-board in two parts, a front and a cap extending longitudinally side by side, said parts each having longitudinal ribs upon their inner faces, and a series of spindle-bear- IOO ing boXes each in two parts clamped together between said front and cap, two of said ribs located respectively, above and below said boxes.

3. A collar-board in two parts, a front and e oep extending longitudinally side by side, said parts each having longitudinal ribs upon their inner faces, and a series of spindle-bearing boxes each in two parts clamped together between said front and cap, each of said boxes 10 provided with an oil-chamber.

In testimony whereofl 1 have hereunto Set my hand in presence of two subscribing witnesses.

HERBERT F. PALMER.
