THOMAS IV. MORGAN, OF VVATERLOO, IOIVA, ASSIGNOR TO WILBUR W. MARSH, OF WVATERLOO, IOWA.
ELASTIC COLLAR-BEARING FOR CENTRIFUGAL MACHINES.
SPECIFICATION forming part of Letters Patent No. 767,524, dated August 16, 1904.
Application file l February 26, 1904:- Serial No. 195,389. (No model.)
To all whom it may concern.-
Be it known that I, THOMAS WV. MORGAN, a citizen of the United States of America, and a resident of Waterloo, Blackhawk' county, Iowa, have invented certain new and useful Improvements in Elastic Collar-Bearings for Centrifugal Machines, of which the following is a specification.
Hy invention relates to elastic collar-bearings for centrifugal machines; and the objects of my invention are, first, to make the bearing sufficiently elastic to be responsive to the sidewise thrust of the shaft, and, second, to provide means whereby the bearing will automatically readjust itself to its true central position when the sidewise pressure upon it has been removed. These objects I have accomplished by the means which are hereinafter described and claimed and which are illustrated in the annexed drawings, in which- Figure 1 is a vertical section of my elastic collar-bearing. Fig. 2 is a plan view of the base-plate with the bearing detached; and Fig. 3 is a reverse plan view of the base-plate, showing the location of the compressionsprings.
Similar letters refer to similar parts throughout the several views.
It is well known that when the shaft of a centrifugal machine is placed in rapid revolution a certain amount of gyration takes place in it, due to a slightly-imperfect balancing of the machine. This gyrating motion of the shaft produces a destructive concussion of the bearing, resulting in breakage and injury or demolition of the machine. This unavoidable tendency of the shaft to gyrate and cause damage to the bearing I have nearly obviated by employing my improved typeof elastic collar-bearing, which responds to all sidewise thrusts, but immediately recovers its central position when the thrust-pressure is removed. WVhile several varieties of elastic bearings are in use, there is shown a lack of means whereby the bearing may be made to always recover its true central position. This defect I have supplied by an improvement embodied in my invention whereby the bearing is caused to infallibly return to its true position when not under strain.
A bearing-box a is furnished with a bushing 0. There is no possibility of the shaft binding within this bushing, as the boxing will always give enough to keep the shaft centrally disposed within it. The boxing a is retained in central position against the baseplate 6 by means of screws f, supplied with compression-springs 6. These screws f pass through holes 9 in the base-plate b and thence into threads in the boxing a. The springs e are interposed between the heads of the bolts f and the face of the base-plate b. In this position when adjusted to the desired amount of elasticity the springs will normally retain the boxing in central position. I/Vhen the shaft within the boxing begins to gyrate, the
elastic springs allow the boxing suflicient displacement to take up the sidewise thrust, and when the thrust is removed the boxing regains its central position. However, without other means of control there would be no certainty that the boxing would regain its true central position. I have supplied the means whereby the bearing must return to its proper place by furnishing the base-plate I) with a raised double-beveled ridge d and recessing the inner face of the boxing a to coincide with the surface of said ridge. The result is that when the boxing is forced away from its center under concussion from the shaft it is lifted up and away from the ridge cl slightly; but when the reaction occurs the boxing falls back into place, where its said recess coincides with the surface of the ridge (Z.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. An elastic collar-bearing for centrifugal machines, consisting of a ridged base-plate, a recessed boxing, and means wherebysaid boxing is elastically linked to said base-plate, substantially as shown and described.
2. An elastic collar-bearing for centrifugal machines, consisting of a perforated and ridged base plate, a recessed boxing, and means for adjustably linking said boxing and said base plate together, substantially as shown and described.
3. An elastic collar-bearing for centrifugal machines, consisting of a perforated and ridged base-plate, a recessed boxing, means for adjustabl y linking said boxing to said baseplate, and elastic means for keeping said baseplate and said boxing normallyin contact with each other, substantially as shown and described.
4. An elastic collar-bearing for centrifugal machines, consisting of a base-plate having a raised double-beveled ridge, a boxing having a recess adapted to coincide with the raised double-beveled ridge on said base-plate, and means for elastically linking said boxing to said base-plate, substantially as shown and described.
5. An elastic collar-bearing for centrifugal machines, consisting of a base-plate having a raised circular ridge, a boxing, and means for keeping said base-plate and boxing together in the same concentric position about a shaft, substantially as shown and described.
6. An elastic collar-bearing for centrifugal machines, consisting of a base-plate having a raised circular ridge, a boxing, means for keeping said base-plate and boxing together in the same concentric position about a shaft, and means for elastically linking said boxing to said base-plate, substantially as shown and described.
