Specification of Letters Patent.
Patented Apr. 22, 1919.
Application filed January 29, 1913, Serial No. 744,843. Renewed January 29, 1919. Serial No. 273,887.
T 0 all whom it may concern:
Be it known that I, CHARLES K. SALIS- BURY, a citizen of. the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented. new and useful Improvements in Belt Driving Connections, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.
This invention relates to centrifugal separators and has for its object to provide a belt drive for a centrifugal separator of the self contained motor type whereby smooth running and high speed is attained with compactness of structure.
Another object of the invention is to provide means for effectively relieving the 1110- tor of its load at starting without dist-urbing the belt connection so that the motor may quickly attain high speed and then its driving connection with the separator spindle be gradually established so as to bring the separator bowl up to the desired speed without materially reducing the speed of the motor.
\Vith the above and other objects in view the invention consists in the centrifugal separator as herein claimed and all equivalents.
Referring to the accompanying drawings in which like characters of reference .indicate the same parts in the diiferent views:
Figure 1 is a front view of a portion of a centrifugal separator constructed in accordance with this invention with the belt driving connection' established;
Fig. 2 is a similarvview thereof with the belt driving connection released;
Fig. 3 is a plan view thereof with parts sectioned;
Fig. 4 is a view looking toward the separator bowl from the position of the driving wheel;
Fig. 5 is a detail view of the belt adjuster in position for establishing driving connections Fig. 6 is a similar view thereof in pos tion for releasing the driving connection; and
Fig. 7 is a sectional plan View of the idle pulley and the support for the guard.
In these drawings 10 indicates a frame construction supporting a motor 11 as herein shown constituting a gas engine with its crank shaft 12 carrying a grooved flywheel 13. The frame 10 also forms a support for the separator bowl casing 14 and its driving spindle 15 which has a grooved pulley 16 held within a housing 17 on a step hearing bracket of the frame. Though the grooved pulley 16 is on a vertical axis and the flywheel 13 is on a. horizontal axis they are connected together by a driving belt 18 which after passing around the flywheel 13 passes over a grooved idle pulley 19 carried by bracket 20 which is adjust-ably mounted on the separator bowl casing 14 as best seen in Fig. 1 and then passes beneath a conical grooved pulley 21 carried at the lower end of a swinging arm 22 which is pivotally mounted on the frame. The conical pulley 21 is on a horizontal axis which is at an angle of approximately 45 with relation to the axis of the pulley 13 and its conical shape permits of the belt lying flat against the face thereof in making the twist between the horizontal pulley 19 and the vertical pulley 16. The pulley 21 on the-swinging arm 22 forms a belt tightener as the arm is under pressure to keep the belt taut. To the lower end of the arm 22 is pivotally connected a handle member 23 which passes through an opening in a guide 24 secured to the frame and a coil spring 25 surrounding the handle member and bearing against the guide 241 and the swinging arm 22 serves to hold the arm in the position shown in Fig. 5 so that the pulley 21 bears against the belt with pressure as shown in Fig. l. The handle member 23, however, may be pulled outwardly against the pressure of spring 25 to withdraw the pulley 21 from the position shown in Fig. 1 to the position shown in Fig. 2 so as to permit the belt to become flexed and in this position it may be held by engaging an arm 26 which pro] ects from the handle member with the guide 24; as shown in Fig. 6. The swinging arm 22 has secured to its lower end a guard finger 27 which reaches around the flanges of the pulley 21 and serves to prevent the belt riding out of the groove of such pulley when the belt tightener is released.
It has been found that on releasing the pressure of the pulley 21 against the belt there is a tendency for the belt to remain in frictional, engagement with the flywheel 13' to a sufiicient extenteto cause a turning of the separator spindle and consequently retard the starting of the engine, all of the slack or looseness of the belt occurring between the top of the flywheel and the pulley 19. In order to prevent this a guard 28, preferably of sheet metal with downwardly turned side flanges and an upwardly turned front end as shown is pivotally mounted by means of a downwardly turned ear at its rear end to the bolt on bracket 20 which supports pulley 19 so as to be adjustable toward or away from the belt between the flywheel 13 and pulley 19. lVhen properly adjusted this guard 28 may be clamped in its adjusted position by tightening the nut on the bolt which is threaded in the bracket 20 as seen in Fig. 7 and it then serves to prethen the gas engine is started in operation and is brought up to the desired speed without turning the separator spindle and when the engine has acquired its full speed the handle member 23 is swung upwardly to carry the arm 26 above the edge of the guide 21 and said arm is gradually permitted to return under the action of spring 25 to its normal position shown in Fig. 5, the belt meantime being gradually tightened so as to start the separator spindle in motion,
gradually.
By means of this invention a driving belt may be employed as the driving connection between a separator spindle and the engine avithout imposing on the engine the burden of driving the separator spindle at the time of starting the engine and without the necessity for shifting the belt from one pulley to another.
What I claim as new and desire to secure by Letters Patent is: v
1. -Means for-- relieving;- a. separator driving engine from its load, comprising the combination with a driven member and its spindle of an engine and its flywheel, a grooved pulley on the spindle, a belt connecting the grooved pulley with the flywheel, an idle pulley receiving the belt from the flywheel, a swinging arm, a tightener pulley on the swinging arm receivingthe belt from the idle pulley, a handle member connected with the arm, a guide through which the handle member passes, a spring for moving the swinging arm, and a projection from the handle member adapted to engage the guide for holding the handle member against the action of the spring.
2. Means for relieving a separator driving engine from its load, comprising the combination with. a driven member and its spindle of an engine and its flywheel, a grooved pulley on the. spindle, a belt connecting the grooved pulley with the flywheel, an adjustable bracket, an idle pulley thereon receiving the belt from the flywheel, a swinging arm, a conical tightener pulley on the swingingarm receiving the belt from the idle pulley, a guard finger on the arm for preventing the disengagement of the belt from the belt tightener pulley, a handle member connected with the arm, a guide through which the handle member passes, a spring surrounding the handle member between the guide and the arm, a projection from the handle member adapted to engage the guide for holding the handle member against the action of the spring, and a guard pivotally mounted on the support for the idle pulley adapted to engage the belt where it leaves the flywheel to prevent a driving engagementof the belt with the flywheel when the belt tigl'itener pulley is held against. the action of the spring.
In testimony whereof, I aflix my signature, in presence of two witnesses.
