PULLEY MECHANISM.
Specification of Letters Patent.
Patented Jan. 11, 1916.
Application filed April 7, 1914; Serial No. 830,136.
To all whom it-mag concern:
Be it known that I, Bmvo'r M. V. HAN- sex, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Pulley Mechanism, of which the following is a specification.
This invention relates to pulley mechanism, the object of the invention being the provision of simple and effective means by which a pulley can be brought into proper relation with a companion pulley irrespective of the size of thelatter.
In thedrawings accompanying and forming part of the present specification I have shown in detail one of the several convenient forms of embodiment of the invention, which to enable those skilled in the art to ractise the same. will be set forth fully in the following description. I do not restrict myself to the details of this disclosure; 1 may depart therefrom in several respects within the scope of the invention defined by the claims following said description.
Referring to said drawings: Figure 1 is a vertical sectional elevation of pulley mechanism involving my invention. Fig. 2 is a transverse section on the line 2f2 of Fig. 1. Fig. 3 is a side elevationof an arrangement of pulleys "employed in connection with a metal working machine and involving my invention. Fig. 4 is a view as seen from the right in Fig. 3.
Like characters refer to like parts throughout theseveral figures of the drawings, which it will be noted are on different scales.
It is the custom now to use electric motors for driving certain kinds of machinery. An electric motor is generally provided with a pulley which serves as a driver, the driven pulley constituting a part of the machine. Also as a part of such a machine is an idler or intermediate pulley; there may in fact be several of such intermediate pulleys or idlers which are also a permanent part of such a machine. When such. a machine is set up it is frequently found that the idlers are not in proper relation with the driver or motor pulley, the consequence being that the pulley of the motor must be changed or different size idlers provided. I provide a construction by which this disadvantage is eliminated, the organization being such that the idler or one of them, if there be a plurality, can be shifted into proper relation with the driving pulley, so that the belt can correctly and accurately pass from the driver to the adjustable idler. The foregomg is merely one use to which the invention can be put, said invention not being restrict ed in this particular but covering broadly the adjustment of a pulley whether it be an idler or intermediate or one of some other character.
Referring now more in detail'to the drawlugs and especially to Fig. 3, the numeral2 designates an electric motor and 3 its pulley which as will be clear constitutes the driver for the drivenpulley 4 Asshown the axes of the driving and driven pulleys are at right angles to each other, but this is not a matter of consequence, nor is it essential that the driving pulley 3constitute part of an electric motor 2, the invention not concerning such details. Between the driving and driven pulleys 3 and 4 is the belt 5 whlch passes over the idler or guide pulleys 6 and 7, the invention residing in means whereby the pulley 7 or its equivalent can be adjusted in such way that the belt 5 will be disposed properly with respect to the pulley 3, this disposition ordinarily being a tangential one. Initially the axes of the pulleys Gand 7 are coincident, but the pulley 7 can be so tippedas to bring its axis of r0- tation at an angle to the. permanently fixed axis of the pulley 6 at opposite sides thereof. The pulley 4 may drive any suitable part for instance the vertical spindle of a grinding-machine. h
The two pulleys 6 and 7 disposed opposite each other or side by side, are sustained by the bearing member 8 which as illustrated consists of a plate, conveniently fastened as by one or more screws as 9 to the framework 10 of the machine with which the pulley mechanism is associated. Projecting from this bearing member 8 and constituting a part thereof is the boxing 11 which directly supports the shaft 12 of the idler 6, the latter being rotative on the shaft 12 which may be secured in place in any desirable manner, for instance by the pin 13. This shaft 12 extends through the hub 14 of the boxing 11, furnished with a lubricato-r 15 for said pulley 6. The pulley 7 is rotatively supported by the shaft 16 which as shown has a square inward extension the tip of the screw 24:. 'sary adjustment has been secured the screw 2 1 will be run in, so that its tip can firmly 18 fitting fiatwise for sliding movement against the opposite flat faces of the cham 'sirable means may be provided, although those shown and now to be described have been found satisfactory. Tapped through what is shown as the bottom wall of the boxing 11 are the screws 22 and 23, while tapped through the upper wall of said box- 'ing is the screw 2 the two screws 22 and 23 engaging one face of the extension 18 while the screw 24 engages the opposite face of said extension, the screw 24 being located between the screws 22 and 23; that is to say the three screws are approximately triangularly arranged. The pulley 7 is shown as occupying its initial or original position in full lines in Fig. 1 and as occupying its shifted or adjusted position by dotted lines in the same view. To shift the pulley 7 from the full line tofthe dotted line position, the following procedure may be adopted: The screw 22 will be backed out the requisite distance, so that the extension can follow the same and swing on the inner end of the screw 23 asa fulcrum. This will carrythe extension 18 away from When the necesengage the extension 18 to thereby clamp the latter and hence securely hold the pulley '7 in its adjusted position. By the manipulation of the two screws 22 and 24, various adjustments can be obtained; in other words the pulley 7 can be swung downward or upward from its horizontal positionto meet the necessary requirements and when an adjustment is obtained the proper screw will be set to maintain the same.
Connected with the extension 181s the lubricator 25 which discharges atits lower end into'the channel 26 having an outlet 27 opening into the groove 28 of the shaft 16 to lubricate the pulley 7. The upper wall of the boxing 11 has an elongated slot 29 through which the lubricator 25 extends and which permits free movement of the lubricator 25 as the extension 18 is tipped or moved endwise in the various adjustments of the pulley 7 What I claim is: l. Pulley mechanism comprising a shaft,
a pulley rotatively supported by said shaft,
the latter having an extension provided with flat opposite faces, aboxing to receive said extension and having flat faces adapted to be slidably engaged'by those of the extension, and means for tipping the' extension in the boxing.
2. Pulley mechanism comprising a shaft, a pulley rotatively supported by said shaft, the latter having ,an extension provided with flat opposite faces, a boxing'to receive said extension and having flat faces slidably engaged by those of the extension, two screws engaging one face of the extension, and a third screw engaging the opposite face of'the extension at a point between those which the other screws engage said extension, the several screws beingtapped through the boxing.
In testnnony whereof I aflix my signature in presence of two witnesses.
