UNIVERSAL JOINT.

1,255,792. Speciication-of Leiters Patent. IRctteinted Feb. 5, 119,118.

Application filed March 13, 1917: Serial No. 154,514.

Be it knownthat I', FRANK S. RHoAns, a

-citizen of the United States, residing at Aurora, in thecounty of Kane and State of Illinois, have invented new and useful I mprovements in Universal Joints, of which the following isa specification. Y c

This invention -comprehends improvements in universal joints and relates particularly to incased joints of this nature having a driving yoke and a driven yoke connected by studs or journals to a ring.

One of the objectsof the invention is to provide a universal joint of this typel which is of extremely simple construct-ion, which has no complicated parts and which may be and quickly Vassembled and disassembled. j l

Another vobj ect of the invention islto generally improve universal joints to render them more practical, useful and commercially desirable. i j;

With these and other objects in view Las will become more apparent as the description proceeds, the invention consists in .certainnovel features of constructiom'combination 'and arrangement of parts asv-will b e hereinafter fully described, illustrated and claimed.

.In the drawinv s,

through my improved universal joint.

the weakening effect of the entrance slots 22,` l I form the ring with an enlargement 211 op- Referring in detail to the drawings by numerals, 1 designates a hub having a peripheral flange 2 on one end thereof which is bolted or otherwise-secured to a knuckle or yoke generally designated 3 having a base plate or disk 4 on -which are formed a pair of arms 5. The hub is connected to a shaft 6.

The" yoke 3 coperatesl with a yoke or knuckle 7 having arms 8 formed integral with a hub 9. Keys or ribs 10 are formed on the interior of the hub 9 and engage the ribs. or keys 11 on the shaft 12 which'has a sliding `movement within 'the hub 9. The arms lof the twofknuckles or yokes extend into a connectingv ring'l land are pivotally connected thereto. The interior surface-of the ring is formed at four. points with fiat faces for. engagementl with the outer faces of the yoke arms as best shown The arms 5 of the yoke 8 are connected to the-ring 13 by a hollow pin 14, the ends of which extend through openings in the lring and form journals. .The pin may be closed at its ends by plugs 15 and is formed-with oil passages 16. Oil or Vgrease may lenter the interior of the pin 14 through the openings 17. Bushings 18 are carried by the rlnggand encircle the terminal portions of the vpin as clearlyshown.y To lock the pin 'against longitudinal and rotational rnove-A ment, I employ a key or lock' pin 19 which may be driven into position through thebase Vplate 4c as'shown in Fig. l1.

i The arms 8 of the yoke 7 are preferably formed with integral studs or journals 20 which may be'slippedinto position within the sockets or openings 21 of the ring through the slots 22.-4 -After the journals 20 are imposition within the ring openings 21, bushings 23 are driven into position and To counteract posite each of the slots as best shown in Fig.

ll.- The journals' 20 are formed with oil passages 25 which may be-closed at their onter ends by plugs=26 and which communi- -cate with the oil assages 27.

. A `casing or the base-plate 4' of the yoke 3 and Acarries a packing-,strip` 30 which bears tightly against the section 29. This last i Y Ye Joint' s formediri sec-` tions 28 and2fi'.A The section 28 is boltedV to' mentioned section is heid in engagement o of oil and grease from the hub 9, I provideV on .the outer end of this hub, a ring or nut 33 which engages a Washer 34 bearing against a packing ring 35.

may be slipped into In Fig. 5 I have illustrated a modified form of my invention. In this form, a' hub 36 is connected to a yoke 37 having arms 38. The yoke 37 coperates With a yoke 39- having arms 40. Each of the yoke arms is formed with an integral journal 4l Which fits Withinan opening 42 in the connecting ring 43. The journals may be slipped into place through vslots 44 in the ring and after they have been positioned, they are secured against displacement by bushings 45 of a larger diameter than the Width of the slots 44. To hold the bushings in position, I employ a retaining ring 46 which is bolted or otherwise secured to one side of the connecting ring 43 and Which is formed With a circumferential laterally projecting ange 47 which seatsl inan annular groove formed'in the periphery of the'ring 43 and in the notches 48 formed in the ings adjacent the outer end.

TheI ring, besides retaining the bushings in position, acts .as a for the* ring 43. I

A casing 49, having the sections 50 and 51 constructed similar to the sections of the first described ca sing, incloses the modified joint and acts as a dust guard and'grease and oil retainer.

Instead of forming the journals integral with the yoke arms, they may be formed separate therefrom and connected thereto as shown inFig. 10. Here the journal 52 is driven into the arm 53 and is reducedadjacent its outer end portion `to accommodate abushing 54. The ring 55 is formed With an opening 56 equal in diameter to the larger diameter of the .journal so that lit position from the eX- terior of the ring.

From the foregoing description taken'in connection With the accompanying drawings, it Will be apparentthat I have provided a universal joint which is susceptible of various modifications, Which is extremely lsimple and practical, Which'is very eflicient,

1n operation, and which maybe easily assembled and disassembled.

While I have shown and described the vpreferred :embodiments of my invention,

side of the bush-- reinforcing member it Willbe clearly understood that I do not Wish to be limited to this construction, but may make such changes as will fall Within the scope and spirit4 of the invention as claimed.

What I claim isz-,- 1. A universal joint including a ring, yokes having arms extending into said ring,

`the ring being formed lWith journal openings, journals connecting said arms with the ring the ring having entrance slots to permit the journals to be engaged with the journal openings, and bushings surrounding the journals, said bushings being of a larger diameter than the Width of the slots.

2. A universal joint including a connecting ring formed with journal openings therein, yyoke members having arms extending into said ring, journals formed on the arms of one of said yoke members, the

ring being provided with entrance slots to permit said journals to seat in the journal openings, bushings surrounding the journalsv and a pin connecting the arms of arms of the other `yoke member with said rings, and means for holding said pin in hosition. y 'i 4. In a universal joint, a connecting ring, bushings therein, yokes, journals carried by the yokes and extendi g into said bushings,

and a retaining ring secured to one side of said connecting ring, the retaining -ringbeing formed With. a lateral ange andthe ico bushings beingv formed With'notches iii-'one side adjacent `their outer ends to accommodate said flange.

5. In a universal joint, a connecting ring having openings, yokes, journals on said yokes received Within said 0penings, the

for said journals, ybushings surrounding the journals of. a greater diameter than the .Width of s'aid entrance slots and a retaining j ring being .also 'provided with entrance slots,
