SPECIFICATION forming part of LettersPatent N0; 781,180, dated J'armary 31, 1905.

i Application tied J'uiy 29, 1904. serial No. 218,651. A

To all whom it may concer-7e: l

Be itknown that I, CHARLEs C. BRABANT, a

citizen of the United States, residing at Al` 4are constructed with aview of cushioning such weight and lateral pull and thrust as are im posed upon them; and it consists in thepeculiar and advantageous hub ofv the type mentioned, hereinafter described, and particularly pointed out in the claims appended.

In the accompanying drawings', forming metrical section of my .improved-hub with some of the parts in elevation. Fig. 2 1s a vsection taken in the plane indicated by the line 2 2 of Fig. 1`. Fig..3 is a transverse section taken in the plane indicated `by the line 3 3 of Fig. l looking toward the left, and Fig.

'A is a detail perspective view of one of the and also has three more or less circumferen# tial grooves c, OZ, and@ and a key-seat f intermediate of the grooves d ande, and B is the casing of my improved hub. The said casing 1s circular in cross-section andismade up of an outer section g, closed at its outer end and open and exteriorly threaded at its inner end and having spoke-sockets 7L on its f perimeter and one or more longitudinal g'rooves c' in its inner side and an inner section Z screwed on the inner end of the outer section and having a large central opening lo.

C is an annulus, of felt or other suitable material, havi'ng a reduced inner portion snugly occupying the circumferential spacel between the collars aand b of the axle, and D is a belvlows, of strong textile or other suitable masaid annulus C and bellows D will accommoi vof the main section.

datethemselves to and in no measure yinterfere with the movements of the hub-casing .with respect to the axle, it will be observed that they will preclude the entry of dust, grit, and the like into the casing, and hence will materially prolong the usefulness of the working parts contained in the casing.

E is a boxing contained in the casing B and held thereto by longitudinal ribs m, disposed in the groovesrl of the casing-section g.

. F is an annular shell arranged within the 1 boxing E and having one or more circumferential grooves n in its perimeterand also hav.- ing lugs p extending inwardly or toward the centerpof the hub from its side edges.

Cr G are antifriction-balls arranged in the grooves n of the shell F and interposed between the said'shell and theboxing E, so as to enable the boxing to bear on and turn around about the saidshell F with but a minimum Aaxle and having its free portion disposed against the inner side of the shell F. I prefer to provide the weight-sustaining spring at its inner end with a collar q,- which surrounds the axle A and has a key-seat r, designed in connection with the key-'seat f' of the axle to receive a key s, which is retained in position by a collar t, screwed'on a threaded portion of theaxle, as best shown in Fig. l.

In addition to the weight-sustaining spring vH the hub comprises two sets of weight-sustaining sp'rings lettered I and J, respectively.v These springsIand J are preferably provided with dovetail inner ends a, and are connected to the axle through the medium of blocks K L, which loosely surround the axle and are designed to turn on antifriction-balls M, arranged in the grooves c, CZ, and e. The blocks K and L respectively comprise a mainl section o, having dovetail grooves w in its perimeter to receive the dovetail ends ofl its springs and also having athreaded end and a cap-section y screwed on said threaded end The dovetail inner ends of the springs I J are removably secured in the main sections of their respective blocks K L by the cap-sections y thereof. y

The weight-sustaining spring H by reason IOO of the interposition of its outer portion or whirl between the lugs p of the shell F is enabled to hold the said shell against lateral "movement in the boxing E, and hence is cal-A culated to efficiently cushion such weight as is imposed upon the middle of the hub-casing. Said springH is also adapted to assist the end series of springs I J in sustaining' such weight and shock and jar as are imposed on the end portions of the hub-casino'.

Interposed between the' ends of the collar q of the spring H and the inner ends of the spring-blocks K and L are the springs for cushioning and taking up shock and jar imposed on the hub incident to lateral thrust or pull. rIhe said springs, which are lettered N, are identical in construction, and therefore a detailed description of the spring shown in Fig. 4 will suiiice to impart an understanding of both. rIhe said spring N, Fig. 4, is formed of a single piece of steel or other suitable metal and comprises a body d, having a central aperture b, adapted to loosely receive the axle A, and curved arms c', extending laterally and inwardlyV from the ends of the body a'. The bodies of the two springs N are arranged to bear against the inner ends of the springblocks K L, and and the arms c' of the said springs are arranged to bear against the ends of the collar q of spring' H. From this it follows that the springs N,which are obviously strong and durable, will serve to eiieiently cushion lateral thrust and pull imposed in either direction on the hub.

It will be appreciated from the foregoing that notwithstanding my novel hub is calculated to prevent the transmission of shock and jar to the frames and bodies of vehicles and machines of various kindsnsuch as traction-engines, threshers, &e.-the said hub is strong and durable and embodies no delicate parts, such as are liableto get out of order after a short period of use.

With a view of preventing injury to any of the parts of the hub when the casing B has a great weight imposed upon it I prefer to provide a rubber annulus T, which is suitably secured on the outer end of the spring-block K. The said rubber annulus will in the event of the casing B being greatly depressed on the axle A, be engaged by the intersection of the casing and will cushion said section in an eiiicient manner.

With the exception of the annulus C, the bellows D, and the annulus T all the parts of my improved hub are preferably of steel.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in my improved hub with a view of imparting a definite understanding of the improved construction. I do not desire, however, to be understood as coniining myself to such specific construction and relative arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.

Having described my invention, what l claim, and desire to seeul'e by Letters Patent, is-

1. In a wheel-hub, the combination oi an axle, a casing loosely mounted on and movable up and down and endwise with respect to the axle, a weight-sustaining coiled spring connected to and surrounding the axle and interposed between the same and the casing, and springs interposed between the axle and the casing and arranged to cushion endwise movement-of the same.

2. In a wheel-hub, the combination of an axle, a casing loosely mounted on and movable up and down and endwise with respect to the axle, a weight-sustaining coiled spring connected to and surrounding' the axle and interposed between the same and the casing, springs interposed between the axle and the easing and arranged to cushion endwise movement oi the same, an annulus surrounding the axle; and a bellows connecting the annulus and the casing and arranged at one end oi the latter.

8. In a wheel-hub, the combination oi an axle, a easing loosely mounted on the axle, a coiled spring connected to and surrounding the axle and interposed between the same and the casing, sets of springs disposed at opposite sides of the coiled spring, and connected to the axle and interposed between the axle and the casing, and springs mounted on the axle and interposed between the connection o1 the coiled spring and the connections of the said sets of springs.

4. In a wheel-hub, the combination oi? an axle, a casing loosely mounted on the axle, an annular shell contained in the casing and having inwardly-directed lugs on its edges, one or more circumferential series oi' antiiriction devices interposed between the perimeter of the shell and the casing, a coiled spring connected to the axle and interposed between the same and the shell, and having its outer portion disposed between the lugs of the shell, blocks mounted on the axle at opposite sides of the coiled spring, springs connected at their inner ends to said blocks and bearing at their outer ends against the casing, and springs mounted on the axle and interposed between the inner portion of the coiled spring and the spring-blocks.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

CHARLES C. BRABANT.
