Letters Patent No. 96,937, dated November 16, 1869.

INIPROVEMIENT IN HAND-SPINNING- MACHINES.

The Schedule referred to in vthere Letters Patent and making part of the lame.

I, CHELTON MATHENY, of Greensburg, Decatur Icounty, Indiana, have invented a certain Spinning- Machine, of which the following is a specification.

This is an improvement in the class of hand-spinning machines whose spindle is mounted in a carriage, capable of being run out or in along a track, for the purpose of drawing and twisting, and taking up the twisted yarn; and

My invention consists in the employment, with such carriage, of a vibrating bell-crank or lever, which enables the operator to apply a positive motion to the spindle-carriage on its outward stroke along the track,

and which also enables the whole length of the ma- ,v ch'inc to be made available for a run or stretch.

Figure l is a perspective view of a machine embodying my improvements, the spindle-carriage being run ont.

Figure 2 shows the machine adapted for ,spinning flax.

A is the bench, supported, in a slightly-sloping position, as shown, by suitable feet, B C, and surmounted by a Trail or track, D, for a 'spindle-carriage, E, substantially similar to that described and shown in mypatent of February 26, 1867,`and whose spindle F is rotated by substantially the same arrangement of cords or bands, G H, and drive-wheel, I.'

The outer stroke or run of the carriage, instead of being eiected by the instrumentality of the customary disk-wheel and belt, as heretofore, is produced by means of a bell-crank, J K, pivoted at some elevation above the bench, and whose short arm or member J is connected, by cord or rod L, with the treadle M, and whose `long arm K is slotted, at k, to receive a pin or wrist, N, which projects from the spindle carnage.

drive-wheel I, with her left knee under the i'ont end of the bench, and her person slightly facing left, and,

having engaged the end vof the roll on the spindle,

simultaneously rotates the drive-wheel and depresses the treadle with her right hand and foot, respectively. Accompanying'this action, the left hand, having hold of one end of the roll, is employed to either increase or relax the draught, as may be necessary; and, by swinging the said hand back, a considerable additional stretch or draught can be imparted. The treadle being liberated, the carriage returns by the combined induen'ce of the spindle-band and the slope forward of the track.

Several decided advantages are obtained'in this arrangement; for instance, the person of the operator being removed to the right side of the machine, the entire length of the track is made availablefor a single run or stretch and,in addition thereto, the operator can, by swinging back her left arm, practically increase the length ot run to any desirable extent. ,y

My arrangement overcomes the annoyance of cessation of the carriage movement outward, in consequence of the slipping or casting of the belt, whenever the latter becomes slack, or the disk-wheel a little out of true.

My arrangement combines the positive motion of the slotted bell-crank with the steadiness of the track. Fig. 2 represents my machine adapted for spinning flax, the ier O being, for that purpose, temporarily bolted to the right side of the bench, and the drivewheel conpected to the` treadle by means of a pitman, P.

I claim, as my invention- 'Ihe combination, in a hand-spinning machine, of a spindlecarriage and 4guide-track, with the bell-crank J K k connected to and operated by the treadle, substantially as and for the purpose set forth.

In testimony of which invention, I 4hereunto set my hand.

CHELTON MATHENY.
