SPECIFICATION forming part of Letters Patent No. 3l1,102, dated January 27,1885.
Application filed June 3, 1884. (No model.)
T0 (ZZZ whom it may concern Be it known that I, JAMES WVITHINGTON, a citizen of the United States, residing at Chambersburg. in the county of Mercer and State of New Jersey, have invented a new and use 'ful Improvement in Belt-Shifting Devices for from a given fixedly and regularly rotating shaft to a shaft parallel with it, each of the pulleys being of the form of a frustum of a cone, and the two pulleys being set with their axes parallel, but being respectively reversed in position.
The specific object of my improvement is the provision of a device by which the belt which communicates the motion of one conepulley to the other cone-pulley can be readily shifted with respect to its position upon the said cone-pulleys, and when shifted shall be accurately retainedin the position in which it is then set. v
The above objects I attain by mechanism, a preferred form of a convenient embodiment of which is illustrated in the accompanying drawings and explained in the following description, the particular subjectmatter claimed being hereinafter definitely specified.
In the drawings, Figure 1 is a top plan view of my device; Fig. 2, an end elevation of the same, sight being taken from the lower side of Fig. 1. Fig. 3 is a side sectional elevation of the apparatus on Fig. 1, on the line a; 00 of said Fig. 1, and sight being taken from the right hand of said figure. Fig. 4 is an elevational view of one of the supporting-frames, and Fig. 5 an end elevational View of one of the traveling framebars of one of the beltshifting frames.
Similar letters of reference indicate corresponding parts.
In the drawings, A A are a pair of conepulleys whose axles pr shafts a a are parallel and supposed supported in any suitable hangers. (Not represented in the drawings.) These cone-pulleys are disposed in the usual mannerthat is to say, at a certain distance apart and in reversed positions-as shown in Figs. 1 and 2. I
B is the cone-pulley belt which encircles both pulleys, and which, assuming that the The contrivances in which the novelty of I my invention resides, and which are devices for shifting the belt 13 and retaining it in different positions with respect to the cone-pul- I leys, are the following:
0 O O O are four supporting frames or hangers disposed in opposite pairs, respectively, by pairs face to face in a manner which will be understood by reference to Fig. 1, and which are supported from the ceiling from which the apparatus as a whole is suspended.
J ournaled, respectively, in opposite supportingframes, near the centers thereof, are two screw-shafts, D D, which are preferably in the same horizontal plane as the shafts of the cone-pulleys, and which are parallel with said shafts. These screwshafts are adapted to be rotated in bearings (Z (Z cl cl, formed in the supporting frames or hangers, but have no axial motion with respect thereto. Upon the I corresponding extremities of each of the two screw-shafts beveled pinions (Z (Z are provided, which pinions mesh with other beveled pinions, c a", respectively, at the extremities of a counter-shaft, E, supported in suitable bearings, e 6, connected with the hangers O O". Upon this counter-shaft is mounted a grooved hand-wheel, e, in the peripheral groove of which is suspended an endless hand-rope, 6*,
the manipulation of which occasions the ro-' tation in either direction of the hand-wheel, and consequently of the counter-shaft, with the result that through the operation of the beveled gears the two screw-shafts are caused to rotate at an. equal speed and in a corre sponding direction, either right or left handed, according to the direction of the rotation of the hand-wheel. The officeof the screwroo shafts is to occasion the longitudinal travel of what I. term the belt-shifting frames, composed of vertical frame-bars f f, connected together at top and bottom by yokesleeves f f and at their centers provided with threaded sleeve-bearings f which embrace the screwshafts. These belt-shifting frames are held in vertical position and guided in their travel by horizontal guide-rods f set, respectively,-
. .10 near the top and bottom ofthe pairs of supporting-hangers, upon which guide-rods the yoke-sleeves f, respectively, travel. Thebelt passes between the vertical bars f f of the belt-shifting frames, and in the movement of I 5 these frames, which are set face to face, and under the actuation of the screw-shafts travel with equal speeds in the same direction, is moved longitudinally with respect to its position upon the cone-pulleys.
In order to keep the belt taut upon the conepulleys, I have provided two belt-tightener rolls, G G, housed in bearings g, which slide upon vertical rods 9, supported on brackets g",erected from the vertical bars f of the beltshifting'frames, as clearly shown in Fig. 5. Spiral springs 9 coiled upon the vertical rod 9, between the bearings g and the upper brackets, 9 serve to retain the belt-tightening rolls down upon the belt with a yielding 3o pressure. V
It is obvious that instead of employing two belt-shifting framesone in connection with or propinquity to each pulley-but one beltshifting frame can be employed, I prefer, 3 5 however, to employ two, as the control of the belt is best effectuated thereby.
I am aware that I am not the first to provide means for automatically shifting the belt of cone-pulleys and for retaining the belt .0 when shifted in given positions, and to such device, broadly, as such, I lay no claim, the novelty of my invention consisting in the specific devices for shifting and controlling the position of the'belt herein describedand claimed.
Having thus described my invention, I 'claim- 1. In' combination, a pair of cone-pulleys, an endless belt traveling thereupon, the beltshifting frames for controlling the position of said belt upon said pulleys, the screwshafts for actuating said belt-shifting frames, the
' counter-shaft, and the miter-gears for connecting the screw-shafts with the counter-shaft, substantially as set forth.
2. In combination, the cone-pulleys, the endless'belt, the belt-shifting frames provided with belt-tightening rolls, the screw-shafts, the counter-shaft, and the miter-gears for connecting said shafts, substantially as set forth.
3. The combination, to form a belt-shifting contrivance, of the belt-shifting frames, the guide-rods, the scrcw-shafts,thecounter-shaft, miter-gears connecting said counter-shaft with the screw-shafts, and the hand-wheel and rope for imparting motion to the counter-shaft, substantially as set forth.
4. The combination, to form a belt-shifting contrivance, of the belt-shifting frames, the guid'e-rods, the screw-shafts, the counter-shaft, miter-gears connecting said counter-shaft with the screw-shafts, means for imparting rotation to the counter-shaft, the cone-pu1leys, and the endless belt, substantially as described.
5. In combination with the vertical bars,
suitably connected together by the yokesleeves, and provided with threaded sleevebearings, the vertical rods, slide-bearings, springs, and belt tightener roll carried .by said slide-bearings, substantially as set forth. 1 In testimony whereofI have hereunto signed my name this 22d day of May, A. D. 1884.
