Application filed September 17. 1914.
1/ b (ZZZ 1 17mm 1' t may concern Be it known that I, Cnanmts l i'. Bonan- MAX, a citizen of the United States. residing at Pa vtucket, in the county of Providence and State of Rhode Island, have in vented certain new and useful Improvements in 'lension-lulleys for Spindle-Driving Mechanism of Textile-Spinning Machines, &c., of which the following is a specification.
My invention relates to textile-spindle driving mechanism and particularly to the construction of tension pulleys, so-called, capable of being employed in connection with such driving mechanism.
The object of the invention is to minimize the Weightof the pulley and cost of construction and increase its etlicieney. the latter being largely due to a reduced degree of centrifugal force and a corresponding saving in the power usually required for rotat ing tension pulleys as heretofore devised.
In the accmupanyiug sheet of drawings Figure 1 represents a side elevation of a tension pulley en'ibodying my improvements, portions of the pulley being broken away; Fig. 2 is a transverse sectional view, in enlarged scale, taken substantially on line 22 of Fig. l; and Fig. 3 is a similar sectional view showing the members in position immediately preceding the act of joining or securing them together to produce the pulley.
In my improved tensioirpulley A, all the members thereof (except the center arbor or axle) are formed of suitable, comparatively thin sheet metal, as steel, having a degree of resiliency, swaged or shaped to the desired form. The said arbor. B, is provided with end journals 5 Z11, and a central portion 6, the latter having any suitable form crosssectionally. In the drawing the part b is represented as polygonal or square.
The sheet metal members composing the major part of the pulley are as follows: (.2 indicates the circular flat centrally apertured disk supported on the arbor, the axis of the latter being perpendicular to the plane of the disk. If desired the central portion of the disk may be strengthened by one or more lateral reinforcing members a. A sheet metal hand 0 snugly encircles the outer peripheral edge of the disk. The band is positioned transversely centrally of the disk and is heat so as to Hive a slightly Specification of Letters Patent.
Patented Aug. 3, 1915.
Serial No. 862,158.
crowning effect to the face of the pulley; this annular band also serves to reinforce the rim portion of the pulley; the ends of the band abutting each other. See 0 The two outer circular side sections or checks (1, (Z of the pulley are formed of sheet metal and given the desired shape by stamping or by other suitable means. The sections d are alike in form and oppositely disposed and arranged to inclosc the said disk and band members between them. section is provided with an integral central or huh portion ('1 and an integral circular rim part ('5 the latter being crowned 0r beveled transversely to conform to the band c. The inner peripheral edges f f of the rim part of the sections are adapted to engage each other and form the smooth circular joint or seam 7, indicated in Fig. 2. The said hub portion of the sections may be stiffened by the employment of washerlike members (1 secured thereto.
In assembling the parts, assuming the disk a to be provided with the reinforcing band (I and also positioned on the arbor B, substantially as represented in Fig. 3, the manner of completing the tension pulley is as follows:The two side sections 6 are placed in opposition on the respective end portions of the arbor and forced toward each other in the arrow directions m; at the same time the inner faces of the hub portions engage shoulders 6 of the arbor and the inner edges f of the respective circular semi-rims to snugly engage each other; in
order to overcome the natural resiliency of Each side the metal the sections are then pressed or.
clamped so snugly against the ad acent surfaces of the center disk a, substantially as shown in Fig.
2; while thus confined the members a and d (I are rigidly secured together in any suitv able manner, as for example, Welding or riveting, the pulley.
In my improvement the plane substantially fiat portions of the side sections and the intermediate or central disk are arranged to be rigidly secured together and form the web part of the pulley, thus stiffening and strengthening it both laterally and torsionally. In some cases the reinforcing or lining band 0 may be omitted, if desired.
It may be stated thafin spindle driving byelectric spot etc, thus completing as to spring the flattened sides mechanism for textile spinning, twisting thereby increasing the efliciency of the pulley.
It is to be understood that the form and arrangement of the sheet -metal elementsherewith described illustrate a preferred example of those parts of my improved tension pulley, and that changes in the shape,
1 size and arrangemen of parts may be made therein without departing from the spirit 'of the invention embodied in the subjoined claims.
I claim as my invention 1. As an improved article of manufacture, a tension-pulley of the character described,
comprisin a'central axle, a circular disk of sheet meta mounted on the axle, an annular/ band of sheet metal snugly encircling th e peripheral edge of said disk transversely, and a pair of oppositely disposed swaged r pressed outer circular side sections atormed of sheet metal, said sections secured to the circular disk and confining it and the metal band therebetween, and having the said axle extending centrally through the side sec tions,
2. A revoluble tension-pulleyconsisting of a pair of she d oppose circular side or check sections 'ormed of s eet metal, each section having acent'ral hub portion and a chambered peripheral rim part, the adjacent edges of the rim part abutting and forming the transverse face of the pulley, a
circular d sk of sheet metal positioned laterally betw en the circular side sections and rigidly secured to them, a relatively narrow band of sheet metal, said band snugly engaging the adjacent circumferential face of the disk and the inner surface of the peripheral rim of theside sections and being inclosed. in the chambered portion of the rim, and a journaled axle extending through the center of the said disk and side sections.
3. In a tension-pulley of the character described, the combination of a circular disk, a strengthening or reinforcing band arranged transversely of said disk and snugly encircling it, a pair of exterior parallel circular side sections registering with each other and having their outer peripheral edges constructed to form a surface adapted to carry a belt and also forming an inclosed space or chamber inwhich said disk and its reinforcing band are confined, means securing the members together, said disk, band andside sections being formed of suitable sheet metal, and a journaled axle or arbor having said members mounted thereon.
4;. A tension pulley comprising a pair of side section s-having central hub and periplr eral rim portions,- said sections formed of sheet metal, a disk, also of sheet metal, positioned concengically between and rigidly secured totlreside sections, and an arbor or z ixle havmg the said sheet metal members mounted thereon,
l'n testimony whereof I have aflixed my signature in presence of two witnesses.
