'NIPENSATING JOURNAL-BEARING.

SPECIFICATION forming part of Lettersvllatent No. 763,077, dated June 21, 1904.

Application filed March 2l, 1904.

To @ZZ whom it may concern:

Be it known that I, MAX F. STADTMULLER, a citizen of the United- States, residing at Pomeroy, in the county of Calhoun and State of Iowa,have invented certain new and useful Improvements in Compensating Journal-Bearings, of which the following is a specification.

In the operation `of machinery, such as cream-separators, considerable vibration is occasioned.

This invention provides a bearing for neutralizing in whole or part the vibration, thereby obviating the noise, the wear and tear, and the manyobjectionable features attributable thereto.

The invention consists of a box, frame, or

and yielding braces between the box and bearing for centralizing the latter and taking up the vibration, said braces unitedly constituting acompensator, the tension of which is regulable to offer agreater or less resistance to the amplitude of vibrations. y

' The invention further consists of a tensionregulator for the said compensator and interlocking means between said regulator and compensator to prevent relative turning when adjusting the parts to vary the tension of the yielding braces.

The invention also consists of the peculiar formation of the yielding braces, the mounting therefor, and an expansible ring passed through the eyes or coils of said braces and holding them in line and admitting of their inward and outward movement, sol as to snugly fit the boX or frame forming a support for the bearing as a whole.

The inventionfn'rther consists of the novel features, details of construction, and combinations of parts, which hereinafter will be more particularly set forth, illustrated, and finally claimed.

In the accompanying drawings, forming a part ofthe specification, Figure l is a side view of a journal-bearing embodying the invention, showing the same in connection with a separator, the lower portion of which is illustrated in section. Fig. 2 is a perspective view of the compensator. Fig. 3 is a Vertical central section of the component parts of the bearing, the same senti No. 199,182. ci@ modem being on a larger scale.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. y .Y

` The compensating journal-bearing is` designed for general application where vibration of a rotary shaft is to be utilized, and inasmuch as it is peculiarly adapted for separators and analogous machinery it is illuswhich the tension of the yielding braces comprising the compensator is regulated. The

rotaryA shaft 3 is snugly j ournaled in the sleeve 5,*so as to prevent any lost movement bentween them. The term sleeve as applied to the part 5 embraces any element that may be used in the capacity of a bearing for the shaft 3,

The compensator is composed -of a series of yielding braces having the forml substantially as shown in Fig. 5 and disposed in a circle, so as to embrace the sleeve 5 and come b etween'itand the box, frame, or like Isupport receiving the journalbearing as a whole. The yielding braces comprise angularly-disposed arms 7 and 8 and one or more coils 9, the several parts being integrally formed and constituting portions of a length of wire bent upon itself intermediate of its ends to form Figi is a perspective' Fig. 6 is a per- IOO the coils and having its end portions extended to provide the arms 7 and 8. When the yielding braces are assembled, the arms 7 are arranged about parallel with the axis of the journal-bearing, whereas the arms 8 are inclined so as to exert a lateral pressure upon the sleeve 5. A ring 10 is provided to connect the yielding braces in series, and said braces have their arms 7 jointed thereto in any substantial and rigid manner. The coils or eyes 9 unitedly form a circle and lie side by side, as indicated most clearly in Fig. 2, said circle of coils being spaced from the supportingring 10. An expansible ring 11 is passed through the coils or eyes 9 and serves to maintain the same in line or proper position and to admit of the coils moving inward or outward to allow for slight variations in the diameter of the recess 3a of the box or support designed to receive the bearing. This expansible ring may, it' desired, serve to supplement the action of the yielding braces, particularly so if made of stout material.

The tension-regulator consists, essentially, of a sleeve 12, having a conical end 13, which is adapted to be forced between the compensator and the bearing 5, so as to increase the tension oi' the compensator as may be desired. The sleeve 12 snugly tits the sleeve or bearing 5, and its conical end is provided with a series of grooves 14, forming seats to receive the inclined arms 8 of the yielding braces or compensator elements. In this manner is provided a positive interlocking connection between the tension-regulator and compensator to prevent relative turning of the parts when the set-nut A is turned either to advance or permit the withdrawal of the regulator, according as the tension of the compensator is to be increased or diminished. Moreover, the seats or grooves 14 receiving the arms 8 hold the latter in iixed position, which is essential to the eiciency of the invention. A series of depressions 15 are formed in the lower or outer end of the tension-regulator and are adapted Y to coperate with a springactuated stop 16, carried by the set-nut, so as to hold the latter in the adjusted position against any possible casual displacement.

The compensating journal may be used in any connection where it is required to take up the vibration of a rotary shaft, and in the arrangement of the parts it is of the utmost importance that the shaft receive a snug lit inthe bearing or sleeve 5 and that the tension-regulator closely encircle said bearing,

while the compensator is snugly received in the box, frame, or support, provision being had for a limited play between the tensionregulator and said box, frame, or support. When the tension-regulator 12 is advanced by means of the set-nut A, the inclined arms 8 are repressed-that is, moved outward by means of the conical end 13 wedging between said'arms and the sleeve -thereby oiering a greater resistance to the vibration of the shaft and sleeve 5, according as may be desired to meet the exigencies of the'case.

Having thus described the invention, what is claimed as new is- 1. In a compensating journal-bearing, the combination of a bearing-sleeve, a series of yielding braces arranged about said sleeve and having inwardly-extended arms, a tensionregulator mounted upon the bearing-sleeve andpositively interlocking with said arms of the yielding braces, a set-nut threaded upon the bearing-sleeve for advancing the tensionregulator, and interlocking means between said set-nut and tension-regulator to prevent casual displacement or loosening of the setnut, substantially as setforth.

2. In a compensating journal-bearing, the

-combination oi' a-bearing-sleeve, a series of yielding braces arranged to encircle the bearing-sleeve, means for varying the tension of said yieldlng braces, and an expansible rlng having loose connection with the yieldingy braces and adapted to hold them in line and to admit of their inward and outward movement, substantially as specified.

3. In a compensating journal-bearing, the combination of a bearing-sleeve, yielding braces arranged in a circle about the bearingsleeve, each comprising an eye and angularlydisposed arms, an expansible ring passed through the eyes of the yielding braces, and a tension-regulator mounted upon the bearing-sleeve and adapted to be advanced thereon so as to compress the yielding braces, substantially as and for the purpose speciied.

4. In a compensating journal-bearing, the combination of a bearing-sleeve, a series of yielding braces arranged in a circle about the bearing-sleeve, each comprising angularlydisposed arms and a number of coils, the several coils of the yielding braces coming together, a ring having said yielding braces connected thereto by one of their arms, and a tension-regulator mounted upon the bearingsleeve and adapted to be advanced thereon so as to vary the tension of said yielding braces,

`substantially as specified.

and adapted to be advanced thereon so as to vary the tension of said yielding braces, and an expansible ring passed through the series of coils of the said yielding braces, substantially as set forth.
