. SPROCKET-WHEEL.A
SPECIFICATION forming part of Letters Patent No. 768,232, dated September 2, 1902. Application filed August 2, l901. Serial No. 701642. (No model.)
To au whom it mag/concern;
Be it known that LVDANIEL CowAN JACK- LING, a citizen of the UnitedStates,lresiding at Republic, in the county of Ferry and State of Washingtomhave' invented certain new and useful Improvementsin Sprocket-Wheels, of which the following is a specification.
This invention relates to sprocket-Wheels in which the teeth are formed independently of the body portion, and particularly to the means of adjustably securing the teeth to the body portion of the wheels, so that their operative diameter or the pitch-linethereof may be increased or diminished, all of which will more fully hereinafter appear.
The principal object'of the invention is to provide a simple, economical, and efficient sprocket-wheel.
A further object is to provide a sprocketwheel of such construction and arrangement that the operative diameter or pitch -line thereof may be increased or decreased the.
desired amount.
Further objects of the invention will appear from an inspection of the drawings and the following description and claim.
The invention consists in the features, combinations, and details of construction hereinafter described` and claimed.
In the accompanying drawings, Figure lis an elevation of one side of a sprocket-wheel constructed in accordance with these improvements; Fig. 2, an elevation showing-the opposite side of a sprocket-wheel from that shown in Fig. l; Figu, a longitudinal sectional view taken on line 4 of'Fig.- 1; Fig. 4, an elevation of one of the disks forming the body portion looking at it from the interior; Fig. 5, a similar view of the other disk which forms the body portion looking at it from the interior; Fig. 6, a large perspective detail View of one of the sprocket-teeth, and Fig. 7 a sectional detail taken on line S of Fig. l looking in the direction of the arrow.
In the art to which this inventionrelates it is well known that there are timeswhen it is exceedingly desirable to increase or diminish the operative diameter of the sprocketwheel-that is,1;o increase or decrease the theoretical pitch-line-to compensate for wear of either the links of the chain or the sprocketteeth. The invention therefore is designed principally to provide afsprocket-wheel by which such an advantage maybe obtained, all of which will more fully hereinafter appear. In constructing a sprocket-Wheel in accordance with theseimprovements I make a body portion composed of'two disks a and b, the latter having a hub portion x extending outwardly from each side thereof. In order to provide the necessary sprocket-teeth and hold them in an adjustable1 manner and in engagement with the body portion of the wheel, a plurality of sprocket-teeth c are provided,each having a shoulder portion d, a supportingbar,portion e, and a lug portionf on the supporting-bar. One of the body-disks b is provided with a plurality of radial grooves or pockets g, into which the supporting-bar portion of the teeth is fitted, andthe other bodydisk is provided with a plurality of camgrooves h, adapted to receive the lug on the supportingbar portion, so that when the parts are in operative engagement, as shown in Fig. 3, the rotation or vibratory movement of the disk a-will causerits cam'to move the sprocket-teethinwardly or outwardly toward or from thel'center of the wheel to diminish or increasefthe operative diameter thereof.
To provide means for rotatably securing the disk portions that form the body of the Wheel together, the body portion bis perforated at tand provided with a number of securingbolts t', and theother is provided with a similar number of concentric elongated-slots 7c, through which theends of the bolts on which the nuts are secured protrude. This latter rotatable disk a is rotatablymounted upon the hub ofthe other disk, so that it may be rotated thereon, and is providedwith a dovetail slot l, 'into which an yoperating-lever m (shownin dotted outline) may be inserted for the purpose of moving the same. disk a has been rotated to increase or diminish the diameter of the sprocket-wheel the de` When theY ICO end for forming a chain-supporting base, and Io bolt-and-nut mechanism for holding the disks and thereby the sprocket-teeth in position, substantially as described.
