HARLEY M. DUNLAP AND DELMER M. PUTNAM, OE BATTLE CREEK, MICHIGAN.
MOTOR MQUN TING.
Application and February 2a, 1924. Serial No. 694,802.
To all whom it may concern:
Be it knownthat we, HARLEY M. DUNLAP and DELMm M. PUTNAM, citizens of United States, residing at Battle Creek, county of CalhoumState of Michigan, have invented certain new'and useful Improvements in Motor Mountings, of which the following is a specification.
This invention relates to improvements in motor mountings.
We have illustrated our'improvements as we hzwe adapted the same for air pumping units, although our improvements may be adapted and are desirable for use in other relations.
The main object of this invention is'to provide an improved motor mounting which serves as a means for maintainin desired driving tension upon the belt.
Objects pertaining to details and economies ofconstruction and operation of our invention will definitely appear from the v detailed description to follow.
lVe accomplish-the objects of our invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.
A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:
Fig. I is a side elevation of an air pump unit embodying the features of our invention. Y
Fig. II is a fragmentary plan view.
Fig. III is a detail section on a line corresponding to line 3-3 of Fig. II, looking in the direction of the arrows.
In the drawing similar reference numerals indicate similar parts in all of the views.
Referrin to the drawing, the base 1 is a casting of esired dimensions to support the parts mounted thereon. 2 is an air pump provided with a driven pulley 3. This air pump is mounted at one end of the base. On the other end of the base we mount a motor 4 having a driving pulley 5 connected to the pulley 3 by the belt 6. These parts are conventionally shown.
' The motor 4 is slidably supported by means of the slide bracket 7 having spaced ears 8 slidably engaging the rod 9 mounted on the base. A supporting shoe 10 supports the other end of the motor, this shoe sliding upon the base.
The rod 9 is arranged parallel with the belt 6 so that the motorslides in a plane parallel with the belt. The ears 8 are substantially spaced and the shoe 10 is of such length and shape that a three-point support is provided for the motor.
A coiled spring 11 is connected t0 the lug 12 on the forward ear 8 and the other end to lug 13 on one of the rod supporting brackets 14.
By thus arranging the parts the motor is supported so that it is substantially free from racking strain, owing to the pull of the belt, and the desired tension is maintained upon the belt. This is of particular importance in air pumps and the like where there is a substantial variation in the load, the load increaslngas the pressure under which the pump is working increases.
Our arrangements are, however, desirable vide for adjusting the motor to take up the stretch of the belt but this is frequently neglected resulting in the tension being reduced to such an extent that slippage 0c 1gufs, frequently resulting in burning of the In addition to the advantage of the auto-' matic adjustment no lubrication is required as is occasioned by a belt tightening idler.
-Having.thus described our invention what we claim as new and desire to secure by Letters Patent is:
1. In a structure of the class described, the combination of a base, a driven unit mounted on said base and provided with a pulley, a motor provided with a driving pulley, a belt connecting said pulleys, a motor supporting slide rod disposed on said base parallel with said belt and below said driving pulley, a motor supporting bracket having substantially spaced ears slidably enwith a driving pulley, amotor supporting slide rod disposed on said base parallel with said belt and below said driving pulley, a motor supporting bracket having substantially spaced ears slidably engaging said rod, and a coacting supporting shoe for said motor, said shoe being freely movable on said base as guided by said slide rod, said supporting shoe being adapted to engage the base between. the vertical planes of said bracket ears whereby a three-point support is provided for the motor.
3. In a structure of the class described, the combination of a base, a motor provided with a driving pulley, a driving belt, a slide rod mounted on said base, a supporting bracket for the pulley end of said motor slidable on said rod, a supporting shoe for the other end of said motor, said shoe being freely movable on said base as guided by said slide rod, and a belt tightening spring connected to said slide and to said base.
4. In a structure of the class described, the combination of a base, a motor provided, with a driving pulley, a driving belt, a support for said motor comprising a shoe d1s- .posed at one end of the motor and slidable on said base, a slide rod disposed at the other end of the motor and transversely of the axis of its pulley, said shoe being freely movable on said base as guided by said slide rod, a motor supporting slide coacting with base, a slide rod disposed at the other end' of the motor and transversely of the axis of its pulley, said shoe being freely movable on said base as guided by said slide rod, and a motor supporting slide coacting with said rod. 7
6. In a structure of the class described, the combination of a motor provided with a driving pulley, a driven pulley, a belt connecting said pulleys, a slide rod disposed in a plane parallel to said belt, a motor supporting bracket slidably engaging said rod, a coacting supporting shoe for said motor, said shoe being freely movable on said base as guided by said slide rod, and a spring connected .to said motor for yieldingly su porting it on said rod to tension said be t. 7. In a structure of the class described, the combination of a motor provided with' a driving pulley, a driven pulley, a belt connecting said pulleys, a motor supporting slide rod disposed parallel with said belt and below said driving pulley, a motor supporting bracket having substantially spaced ears slidably engaging said rod, a coacting supporting shoe for said motor, said shoe being freely movable on said base as guided by said slide rod,'and a spring connected to said motor whereby tension is applied to said belt.
In witness whereof, we have hereunto set our hands.
