TO ALL WHOM IT MAYOONCERN:

Be it known that I, ANTON ZWInBEL, of Burlington, in the county of Racine, and State of Wisconsin, have invented a new and improved Universal Joint; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a'side view of niyiuniversal joint. y

Figure 2 is a vertical cross-section ofthe same, the pla-ne of sectionbeing indicated by' the line .er a, fig. I.

Figure 3 is a longitudinal sectional view through one of the knuckles and shanks.`

Figure 4 is a cross-section of the same.

Similar' letters of reference indicate like parts.

The object of this invention is to construct a universal joint that is to be used especially on threshing machines, which is made without projecting bolts er pins, and which can bc easily1 taken apart for renewing the knuckle-pins when the same are worn out.

The invention consists in arranging long shanks for the attachment of the arles to the knuckles. 'Ihese knuckles are provided with wooden pins, which turn in proper bearings 1in `the ring. Said knuckles are so arranged that they can be easily removed from the ring, so that the aforesaid wooden pins may be renewed when they are worn out.

The universal joints now used are very dangerous, by reason of bolts and joints projecting beyond the ring, and many accidents have already occurred on this account. My invention not only overcomes this difficulty and objection, but is furthermore so constructed that it will lastfor a very long time, as the wooden pins can be easily renewed when worn out. i

A is the ring, which is made of cast iron or any other suitable material. Within the saine are arranged fouripairs of semicircular flanges, a a. and I) b, which form the bearings for the knuckles. Each pair, a of these flanges is arranged so that the pin B of the knucklesY can be inscrtedbetwecn them. Two pairs of these flanges are arranged on either end of thc ring A in such a manner that the pins of the knuckles will be held therein at right angles from each other. The wooden knuckle-pin B is secured in the end of the shank C, which is provided with a. ring, e, at its end, for the reception of the pin B. The shank C itself'is provided with a square hole, (see figs. 3 and 4,) so that the shaft maybe easily attached thereto. From each end of the ring C, throughwhieh the pin B` passes, projects a lip, d, as shown in lig. 2. The knuckle can be secured or placed into the ring, by laying the shank upon the edge of the ring. The pin B will then pass into the space between the anges a and b. But as soon as the shank is turned the lip nl will also be brought between the flanges, and the knuckle is then rmly held in thc ring, and can be removed only by turning it'to one side as far as possible, so that th'e shank rests upon the edge of the ring.

Both knuckles are arranged alike, and operate both as described. When the wooden pin is used up it may be easily replaced; and the whole device is therefore simple, compact, and easily repaired, and its use is not connected with any danger to the attendants of the machine.

What I claim as new, and desire to secure by Letters Patent, is

The combination of the ringl A, having semicircular flanges a I), wooden pin ]3, lips d on knuckles c, and shank C, all constructed as described for the purpose specified.

ANTON ZWIEBEL.
