sPEoIFrcArIoN forming part @rimettere Patent-No. evzseaeatsd :my e; 190i.` d l f Application ledNovemb'erl, 1900. `Serial No. 36,548.y `(No niodlf) f To all whom, it may cortccrwrY Be it 'known that 1 GEORGE B, KINSLER,a citizen of the United States of America, residing at Hartford, inthe countyof Hartford and State of Connecticut, have invented new and useful Improvements in' Universal .l'oints,*of

which the followingisa'specication. j

4 This invention relates to the construction of universal joints, the object beingto provide animprovedarticle of this class which is adapted to-beused between parts of shaft-l ing and in other devices wh: we a greater al1.-V gieV of incline is desired between the jointconnected parts than has heretofore been attaiuable,'and, furthermore, to provide a joint of this class in .which the'torsionalstrain between the parts lthereof at all'points inthe movements et the same is equal; and thein vention consists in the peculiar construction and arrangement of the4 parts ofthe device,A

all as hereinafter described and more pari toothed wrench for turning them, or, if preticularlypoiuted out in ythe claims;

In the drawings forming part of' this-speciication, Figure 1 isa sidedalevation showing' mty-improved universal joint applied to and uniting two sections of shaftingor Inetal bars.

Fig. 2 isa longitudinal .section of the parts i,

shown in Fig'.` l. Fig. 3 is a transverse section on linel3-3, Fig. -Y

Referring to thefdrawings, 'A A -indicate two pieces ot"v metal bars or chatting, eachofV which has two parallel ball-engaged arms projecting from one end thereof, whose outer vsides-are preferably in,` thel plane roffthe sur' 4face of said shaft parts and'whose inner walls are pa'rallel,-thu `s providing'a suitable spacebetween said arms for the introduction of ballbearing devices, .as below described. Eachof said' four arms 3 has a nuti t'ted therein which is adjustable toward and from I Said nuts have sockets in their outer ends to receive a ferred, they may be slotted for a screw-driver.. Each of said nuts has yin its inner end a semispherical ball-recess;A Abad-engaging metal t ,block A5, of suitable dimensions to enterfreely between the extremities of said four arms', has'semispherical` recesses in its side walls opposite the like recesses in said nuts, and when said block is so placed, with a fball 6 inten posed, `as shown in Fig. .3, betweenjeach of said nutsand the adjoining side of said block and'each nut screwed upito proper contact the said two pairsfoi armsS is completed. i

'Itwill be noted by referringftofFigB that when' the blocl 5 is imposition betweenthe arms 3 of the shaft-section said block is of slightly'smaller dimensionl than the area in-6o closed'by said arms. The object ot this constructionis to leavea little'roomiforthe'adjustinent of the-'nutse'toward the side -of said-:block to take up the'wear, either oftheA balls or tliesockets in which they'rcst, should 65 litbecome necessary todo so. v

fflA great advantage in making "a joint as vabove described lies in the fact. that lthe block 5, theV balls 6, and the screws' Il may all be'hardened, andffurthermore, any`- one of 7o '-the' balls or screws may easily be removed and. replaced without disturbing the othersf Furthermore', the balls, which` are, inetect, loose spherical beariu gs for the shaftsections to swing on, permitsaidfsections to be moved 75 freely in any 'direction of 'inclination oneto .the other withinvthe limits ozthe construeA tion without receivingany increase of eiort.

' -in-eecting the rotation of" said sections.

` Having thus described my'invention, what 8o 4I.. cla'i`m, and desireto secure by Letters Pat-j i ent oi the United States, is-e 1; A universal joint comprising two'shaft sections, two oppositely-located'arms on each of the sections, aloose block located between 8 5 the-ends ot said arms, balls' interposed between said arms and said block and supported partly in each, whereby said balls mayv serve as movable bearings for said shaft-sections, and together with said block as inter- 9o locking means therefor, substantiallyl as described.

2. A universal joint comprising two shaftsections, two oppositely-located arms on each of said sections, a screw inthe end of each 95 armathe axis of which screws are at right angles to the axis of the shaft-sections, a ballrecess inV the end of said screws, a ball-re# ceiving block located between the said arms,

ballsrecesses in said bloclrfopposite the ends we withitsballtheoperative connection between 55i of said screws, and ballslying partly in the" recesses in said screws and partly in those in d said shaft'parts, a ball-engaging block intersaid block, substantially as`described.

3. A universal joint comprising two shaftsections, two oppositely-located arms on each of said sections, a ball-receiving block 1ocated between the armssof the latter and hav ing ball-recesses therein, balls in saidrecesses, and means in said arms for holding said balls in the recesses in the block, in the .saine plane whereby said balls may serve as pivetal points for the latter, and as interlocking means between said shaft-sections, substantially as described.

l 4. A ball-bearing connection between vparte of shafting'or'similar structural elements comprisingr two ball-engaging arms on each of mediate of said arms, and a bearing-ball in.

termediate of each of said arms and the adjoining sid'e ofsaid block,substantally as described. f

5. A ball-bearing connection between parts of shaftin'g or similar structural elements, comprising two ball-engaging arms on each of said shaft parts, a ball-engaging block in termediate of said arms, and a bearing-ball intermediate of each of said. arms and the adjoining side of said block,l and means for adjusting the contact pressure of said ballengaging parts thereagainst, substantially as described. 1
