B. A. BAILEY, OF LEWISTON, MAINE.

IMPROVEMENT IN SPINNING-FLI ERS.

Specification forming part of Letters Patent No. 57,065, dated August 14, 1866.

To all whom it may concern Be it known that'I, B. A. BAILEY, of Lena iston, in the county of Androscoggin, in the State of Maine, have invented certain new and useful Improvements in the detailof construction of SpinningFliers; and I do hereby declare that the following, taken in connection with the drawings which accompany and. form part ot'.this specification, is a description of my invention sufficient to 7 enable those skilled in the art to practice it.

This invention relates to improvements in the detail of the construction of that part of the flier by which it's presser-finger is kept pressed against the bobbinor cop, said improvements rendering the construction heater in appearance, stronger in wear, and more convenient in adjustment than are the previous constructions for the same purpose.

Of the drawings illustrating my invention, Figure 1 shows a flier in elevation, and Fig. 2 shows the hollow arm thereof in section, taken in the line 2 z, with the presser-finger and my improvements therewith connected in plan.

The hollow arm of the flier is marked a, the ].')I'6SSB1-fillg6l I), and its shaft 0, this working in suitable bearings 61 dfixed to the arm a.

Upon the shaft 0 is secured the piece e, with its lower end in contact with the lower hearing d, and having fashioned upon it the stops marked f f, the function of which is to check within given limits the vibration of the presserfinger b toward and away from the center of the bobbin or cop by abutment against the arm a.

The upper part of c is made into one-halfof an inclined notch-coupling. The other, or upper, half of the coupling is marked 'g, and is placed loosely on shaft 0, but is connected with the spiral spring h, also loosely surrounding cal movement of the finger when the parts become worn by always keeping the piece 6 pressed downward against the lower bearing,

the upper bearing resisting the thrust of the spring.

The spring h is prevented at its upper end from turning freely around shaft 0 by means of a check made from' itself, having its upper coil shaped, as seen in Fig. 2 at i, so as to abut against the hollow arm a of the flier, the end of the coil being bent back and returned to one' of the coils of the spring, to which it is united by brazing or solder. The lower end of the spring h is secured to the piece 9 by being let into a slotformed therein, as seen at s, Fig. 1, the lower end of the spring being bent outward so as to enter the slot, in which it may be held by solder orby pinching or driving the metal ofg over the top of this end of the wire.

It will be seen that the amount of pressure with which the finger I) is thrown toward the bobbin can be increased by simply turning the part 9 of the clutch in the direction allowed by the inclines shown in Fig. 1, and that the pressure may be diminished by moving the piece gtoward the upper bearing, so as to disengage the parts of the coupling, and then al-' lowing the coiled spring to unwind a little.

1. Constructing the abutting-check of the spring h from its own wire at the upper end thereof, substantially as shown and described.

2. In combination with the shaft 0 and spring h, the clutch g 0, when constructed,

arranged, and operating substantially as described.

3. The combination, with the part c of the clutch, of one or both of the stops f, as described.
