SPINDLE.

SPECIFICATION forming part of Letters Patent No. 586,789, dated July 20, 1897. Application filed April 19, 1897. Serial No. 632,796. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALFRED GARTNER, a citizen of the United States, residing in Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Spindles; and I do hereby declare the following to be a full, clear, and ex act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my present invention is to provide spinning-spindles for silk, cotton, &e., with simple means for overcoming or counterbalancing the strain exerted by the driving belt or band upon the sleeve-whirl and the spindle operated thereby, of simple construction, reliable and efficient in operation, not liable to get out of order, and applicable to spindles of various make and construction.

The invention consists in the arrangement of an auxiliary wheel or pulley on one side of the whirl of a spindle and diametrically 0pposite the driving means for the same and carried by the spindle-supporting tube and of an endless band or belt passing over the said wheel or pulley and the driving means and in frictional contact with the whirl, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in the two views, Figure 1 is a top plan View, partly in section, of a spindle-rail in which are mounted a series of spindles of ordinary construction and pro vided with my improvements, only that portion of the driving mechanism being shown which is necessary to fully illustrate the nature of my said invention; Fig. 2, a side elevation of one of said spindles and its driving mechanism, the spindle-rail and the shaft of the driving-wheel being shown in section.

In said drawings, (t represents the spindlerail, in which is mounted the bolster b, containing the bearings for the spindle c, which latter is provided with a sleeve d and whirl d, all of the usual and well-known construe tion.

In the base or flange of the bolster, or in a bracket or projection m carried thereby, is arranged a vertical pin or axle 'i, on which is loosely mounted an auxiliary wheel or pulley h. Said wheel or pulley h is arranged sub stantially in the plane of the whirl and is engaged by the endless belt 6, passing over the driving-wheelf on shaft g, and which belt is in frictional contact with the whirl d.

It must be remarked that the wheel or pulley h is arranged in front of the spindle 0 when viewed from the front of the machine and that its supporting pin or axle t' is diametrically opposite the driving-wheel f.

The whirl d, which, according to the above, is intermediately arranged between the driving-wheel f and the auxiliary pulley or wheel 71, is engaged by the driving band or belt 6 at two places diametrically opposite each other, and the strain exerted by one half of said band or belt c upon the one side of the whirl (Z is counterbalanced by the strain exerted by the other half of the band or belt upon the opposite side of said whirl.

Almost the entire strain of the driving band or belt is thus taken up by the auxiliary wheel or pulley 7t, and the spindle is free from said undue strain. The friction between the said spindle and its supporting-bolster is thus greatly reduced and the device itself rendered more durable and more effective, as will be manifest.

As the auxiliary wheel or pulley h is carried by the bolster, the yielding motion of the latter is transmitted to the said auxiliary wheel or pulley, and therefore the frictional contact between the engaging portions of the endless belt or band and the whirl is not changed or varied sufficiently to interfere with the proper working of the spindle.

I do not intend to limit myself to the precise construction shown and described, as various alterations can be made without changing the scope of my invention.

Having thus described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a sleeve-whirl spindle and its supporting-bolster, of an auxiliary Wheel or pulley on one side of the spindle and carried by said bolster, driving means on the opposite side of said spindle, and an endless belt passing over said driving means and auxiliary wheel or pulley and intermediately engaging said Whirl of the spindle, substantially as and for the purposes described.

2. The combination With a sleeve-Whirl spindle and its supporting-bolster, of an auxiliary Wheel or pulley arranged substantially in the plane of the Whirl and on one side of the spindle and carried by said bolster, driving means on the other side of said spindle, and an endless belt passing over said driving means and auxiliary Wheel or pulley, and intermediately engaging said Whirl of the spindle, substantially as and for the purposes described.

3. The combination Wit-l1 the bolster, of a sleeve-whirl spindle revolubly arranged in said bolster, a vertical pin or axle on one side of the spindle and carried by said bolster, an auxiliary Wheel or pulley loosely mounted on said pin or axle, driving means at the other side of the spindle, and an endless belt passing over said driving means and auxiliary Wheel or pulley and intermediately engaging said Whirl of the spindle, substantially as and for the purposes described.

4. The combination with the bolster, of a sleeve-Whirl spindle revolubly arranged in said bolster, a vertical pin or axle on one side of the spindleand carried by said bolster, an auxiliary wheel or pulley loosely mounted on said pin or axle and substantially in the plane of the Whirl, drivin g means at the other side of the spindle, and an endless belt passing over said driving means and auxiliary Wheel or pulley and intermediately engaging said Whirl of the spindle, substantially as and for the purposes described.

5. The combination with a sleeve whirl spindle and its supporting-bolster, of an auxiliary wheel or pulley on one side of the spindle and carried by said bolster, and being of smaller diameter than the Whirl, driving means on the other side of said spindle, and an endless belt passing over said driving means and auxiliary Wheel or pulley and intermediately engaging said Whirl of the spindle, substantially as and for the purposes described.

6. The combination with the bolster, of a 7. The combination with the bolster, of a sleeve-Whirl spindle revolubly arranged in said bolster, a vertical pin or axle on one side of the spindle and carried by said bolster, an auxiliary Wheel or pulley loosely mounted on said pin or axle and substan tially in the plane of the whirl, and being of smaller diameter than the Whirl, driving means on the other side of the spindle and diametrically opposite the said auxiliary Wheel or pulley, and an endless belt passing over said driving means and auxiliary Wheel or pulley and intermediately engaging said Whirl of the spindle, substantially as and for the purposes described.

In testimony that I claim the foregoing I have hereunto set my hand this 2d day of April, 1897.

ALFRED GARTNER.
