PHINEAS FEATHER, OF STOW, MASSACHUSETTS.
SPlNDLE-BAND TENSION-REGULATOR FOR SPINNING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 459,454, dated September 15, 1891.
Application filed October 17, 1889.
To all whom it may concern.-
Be it known that I, PHINEAs FEATHER, of Stow, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Spindle-Baud Tension-Regulators for Spinuing-lilachines, of which the following is a specification.
My invention relates to spindleband tension -regulators for spinningmachines; and my improvements consist in such a regulator having the tension-pulley mounted on a diagonally-pivoted arm, whereby the tension on the band will be caused by the gravitation of the arm and pulley.
My improvements also consist in attaching an adjustable weight to such arm to increase its gravitating capacity.
In the accompanying drawings, Figure 1 illustrates in plan a portion of a spinningmachine with one form of my improved regulator applied thereto. Fig. 2 is a transverse vertical section of the same, enlarged, with most of the spinning-machine broken away. Figs.-3, 4, and 5 represent details of the regulator. Figs. 6, 7, S, and 9 are views of modifications.
Similar letters represent like parts in all of the figures.
A represents the whirls or pulleys of the spindles.
B is the driving-cylinder, and O is the spindie-band, which passes around said pulleys and cylinder and which gives the revolutions to the spindles.
In Figs. 1 to 5, D is abracket having several pivotal sockets a a and which is secured to the side of the frame E or to the side of a vertical support under the band C and between the cylinder-shaft and spindles. The bracket D is secured in a position with its pivotal sockets sloping obliquely downward away from the cylinder B.
F is an arm having one or more longitudinal slots I) Z) and also a downwardly-extending pin or stud 0 near one of its ends, which is adapted to enter one of the sockets to in the bracket D and which constitutes the pivot of said arm.
G is a pulley, around which the spindle-band passes to get the necessary tension, and II is Serial No. 327,351. (liq model.)
a weight having screw-threaded holes cl at various distances from its center.
I is a screw-bolt having a lower threaded portion 6 and enlarged smooth and cylindrical middle portion f and enlarged head g. The bolt I passes through the central hole in the pulley G, with the cylindrical portion forminga journal for said pulley, and the screwthreaded portion 6 of the bolt passes through a washer h, through one of the slots 17 of the arm F, and into one of the holes (I in the weight H. The shoulder formed by the lower end of the cylindrical part of the bolt I and the Washer h serve to hold the pulley G and,
weight H in fixed position by tightening said bolt and weight upon the arm F, and the slot or slots 7) allow of longitudinal adjustment of said bolt, weight, and pulley on the arm F. As the bracket D slopes downward in a direction away from the spindles and their whirls and the sockets are formed in said brackets at right angles to its slope, the pivotal supports for the arm F, pulley G, and weight II will be inclined away from the spindles and compel said arm, weight, and pulley to drop away from the spindles and whirls, as shown in Fig. 2.
In Fig. 1 I have shown the application of two regulators to a spinning-machine. The spindle-band G will pass around the cylinder B, then around one of the spindle-whirls A, then around the pulley or pulleys G, and thence around the spindle-whirls A and cylinder B alternately, as shown in Fig.1. Since the pulley G and its supporting-arm are pivoted on a decline, so as to swing downward in a direction away from the whirls A, the
weight of the parts will cause the outer end of said arm to fall and the pulley G to drop againstthe band C and cause the requisite tension to the band. (See Fig. 2.) The weight will assist the gravitation of the pulley G and increase the tension of the band 0. By adj ustment of the pulley G toward andfrom the pivot c of the arm F the extent of the 9 are of movement or sweep ofthe pulley may be varied. The effective leverage of the weight H, the weight remaining unchanged in position, will at the same time be varied by this adjustment. Adjustment of the weight H .from the spindle-whirls A, and this gives means for taking up or decreasing the slackness of the band C. In place of the slots Z) 1) holes it may be made through the arm F, as shown in Fig. 6, and the adjustment would then be made from one hole "i to another, instead of along the slot b.
The arm F and the weight H may be combined in one piece, as shown in Figs. 6 and 7, and in this case the arm portion should be provided with screw-threaded holes 2' in. place of the slots b b, in which the bolt I should be screwed. The tension of the band would then be adjusted by changing the position of the bolt I into another hole 7 A very simple form of regulator I have shown in Figs. 8 and 9, in which the weightK is pivoted to the under part of the arm F,and in this case the tension is increased byswinging the weight out beyond the end of the arm F, so as to increase its leverage on said arm.
My improved regulator gives a combined double tension upon the spindle-band, one caused by the gravity of the pulley and the arm F on its inclined pivot, and the additional tension caused by the added gravity of the weight.
It will be evident that certain details of the construction may be varied without departing from my invention.
What I claim as new, and desire to secure by Letters Patent, is-
' 1. A spindle-band tension-regulator consisting of a swinging arm having a downwardly-extending stud 0 near one end and a pulley supported upon said arm, in'combination with a bracket having an oblique downwardly-extending socket or sockets in which said stud loosely rests and is adapted to rotate, all substantially as and for the purposes described.
2. A spindle-band tension-regulator consisting of a swinging arm having a downwardly-extending stud 0 near one end and a pulley and weight supported on said arm, in combination with a bracket having an oblique downwardly-extending socket or sockets in which said stud loosely rests and is adapted to rotate, all substantially as and for the purposes described.
3. A spindle-band tension-regulator consisting of a swinging arm having a downwardly-extending stud 0 near one end and a pulley and an adjustable weight supported on said arm, in combination with abracket having an oblique downwardly-extending socket or sockets in which said stud loosely rests and is adapted to rotate, all substantially as and for the purposes described.
4. A spindle-band tension-regulator consisting of the combination of a swinging arm having a downwardly-extending stud c at one end and carrying a weight at its other end, a pulley supported upon said arm, and the bracket having an oblique downwardly-extending socket or sockets in which the stud c is adapted to loosely rest and rotate, all substantially as shown, and for the purpose described.
5. A spindle-band tension-regulator con-' sisting of a swinging arm provided with a downwardly-extending stud c and having openings extending through the same from.
