HENRY P. WHITE, OF KALAMAZOO, MICHIGAN.

SPEED-REGULATOR;

SPECIFICATION forming part of Letters Patent No. 721,406, dated February 24, 1903.

Application filed $eptember 18,1902. Serial No. 123,913. (Nb model.)

To all whom it may concern:

Be it known that I, HENRY P. WHITE, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in S peed-Regulators, of which the following is a specification.

This invention relates to improvements in speed-regulators of the cone-pulley type, in which tapered cones-such as are shown in my Letters Patent No. 703,027, issued to me June 24., 1902, and No. 708,439, issued to me on September 2, 1902as distinguished from step-cones are employed. This invention is in some respects an improvement upon the speed-regulators described in said Letters Patent, it being a somewhat difierent embodiment of the principles there disclosed, and is particularly adapted for use in certain relations.

The objects of this invention are, first, to provide an improved belt-driven-conc speedregulator having cones lying in the same or different planes and in which all portions of the contact-surface of the belt travel at the same relative speed and are maintained at an even tension, thereby dispensing with the compensating slip of the belt due to the usual construction; second, to provide an improved belt-driven-cone speed-regulator havingv cones lying in the same or different planes,

in which the division of speeds may be taken at any point between the two extremes at which the machine is designed to run and without in any manner aifecting the tension or friction of the belt; third, to provide a beltdriven-cone speed-regulator having cones ly ing in the same or different planes, with ef ficient and practical means of securing the variations in speed; fourth, to provide a speed-regulator of the'cone-pulley type which is also effective as a power-regulator; fifth, to provide a speed-regulator of the belt-drivencone-pulley type which may be adjusted to automatically govern its load or which may be run under different loads without any adjustment up to the full capacity of its belt.

Further objects will definitely appear in the detailed description to follow.

I accomplish the objects of the invention by the devices, means, and mechanism described in this specification.

The invention is clearly defined, and pointed out in the claims.

A structure embodying the features of my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a side elevation view of my improved speed-regulator, being illustrated as applied to a counter-shaft and to the drivingshaft of a machine to be operated, which is shown in conventional form. Fig. 2 is a detail sectional view taken on a line corresponding to line 2 2 of Fig. 1. Fig. 3 is a detail plan view of the belt-guiding idlers and their supports. Fig. at is a side elevation view of a modified structure in which the cone-pulleys have the same axial line.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the severalviews.

- Referring to the drawings, the parts A are shaft-hangers, which are provided with suitable bearings A for the. shaft B. Thepulleys O O are connected to the shaft by a suitable clutch mechanism, so that the shaft B may be driven in either direction, as desired. The pulleys C are preferably connected with the same power-shaft by straight and crossed belts, so that they are driven in opposite directions. The cone-pulley B is keyed to orotherwise secured to the shaft B, so that it is revolved therewith. The clutch devices are controlled by the lever D, which is pivotally mounted on the bracket D at d and is arranged within convenient reach of the operator. .Mounted upon the driving-shaft I of the machine to be operated, which is here shown;

in conventional form, isa driving-cone J. The cones J and B are arranged oppositely in respect to their-taper-that is, their corresponding ends'point in'the opposite-directions. The driving-cone may be mounted upon the shaft of the machine to be operated, as is illustrated in Fig. 1, or may be arranged as in Fig. 4 in the modified structure, wherein the axial line of the driven cone and the driving-cone coincide. The driving-cone is then connected to the machine to be operated by a suitable belt or otherwise, as may be desired, to suit the particular arrangement or machine which it is designed to operate. The cones are connected by the belt K, which is passed over the guiding-idlers F. The idlers F are mounted upon arms F, which are pivotally connected by the pin f to the upwardlyextending brackets E on the frame or carriage E. The carriage E is mounted upon a suitable track or way E, which is secured to the hangers A above the shaft B. The carriage E is moved back and forth on the way E by a lever 11, which is secured thereto and pivoted to the bracket G at h. The lever H extends into convenient reach of the operator, so that by shifting the same the carriage may be moved back and forth upon the way. The arms F, carrying the idlers which guide and support the belt, are held normally upward by coiled springs e. The cones and belt-guiding idlers are so arranged in relation to each other that when the belt is guided onto the inner end of one pulley-it will be guided onto the outer end of the other, the cone-pulleys J and B lying in different lateral planes. In passing over the idlers F the belt K is guided and turned so that the same edge is always presented to the corresponding end of each cone, and the friction and tension of the belt being uniform throughout the same relative speed is preserved at every portion of its contact-surface.

When it is desired to use this device as a power-regulator which automatically governs its own load, the pairs of arms F are secured together by the pins 7;, (see Fig. 3,) suitably perforated ears being provided on the arms to receive the pins. When thus arranged and the tension properly adjusted, any resistance which is in excess of the tension of the springs e to the power delivered will cause the belt to slip. When the arms F are free, the Work of the belt is its full capacity, provided its friction-surface is equal to its strength.

In the modified structure shown in Fig. 4: the shafts B B, which support the cone-pulleys B and J J, are in the same axial line, the bearing L serving as the bearing for both shafts.

Tight and loose pulleys M are provided for the shaft of the driven cone B, and a suitable pulley N is provided for the shaft of the driving-pulley J, by means of which the device is connected to the machine to be operated.

In operation with the parts arranged as in Fig. 1 the driven cone B receives the power and is driven in either direction, as may be desired, through the pulleys O O and Will transmit the power through the belt K to the driving-cone J, from which it is delivered at various speeds, as desired, the desired variations of speed being secured by shifting the carriage E along the way E by means of the hand-lever 1-1. As the cone B and J lie in different lateral planes, by shifting the carriage E the position of the belt on the cones may be whatever is desired to get any required speed between the maximum and minimum speeds of the device.

By means of the loose pulley J, arranged on the shaft of the driving-cone J and adjacent thereto, the machine is under perfect control and disconnected when the belt is shifted, as appears in the drawings. By this arrangement the speed and the operation of the machine are under the perfect control of the operator, as by simply throwing the lever H the speed may be changed as desired, or by shifting it to the extreme position, as indicated in the drawings, the belt is thrown upon the loose pulley J and the machine thus disconnected from the power, all by the action of one lever. This avoids the necessity of the operator disconnecting the power from the speed-regulator and gives the belt of the regulator the advantage of always be ing in motion, and also relieves the operator of the necessity of even touching the belt with his hands.

My improved speed-regulator is adapted for use in various relations, although itis particularly adapted for use in connection with machines which would have their revolving portions in a plane parallel to the plane of the driven cone of the speed-regulator. In this list might be mentioned enginelathes,milling-machines,planers, shapers,&c. It is also particularly applicable for use as a speed-regulator for street-car orautomobile control,and is especially adapted for use in all lines of variablespeed counter-shaft and power-transmitter service. It will be observed that it is easily adapted to the uses required and that it is very simple and economical to construct.

I have illustrated and described my improved speed-regulator in the formpreferred by me on account of its simplicity in manufacture and convenience in use. I desire to state, however, that I am aware that it is capable of being greatly varied in structural details without departing from my invention.
