TO ALL WHOM IT MAY CONCERN:

Be it known that I, E. D. TYLER, of Gibson, in the county of Susquehanna, and State of Pennsylvania, have invented a new and useful Improvement in Felloe Dowel-Pin; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents my improved tubular metal dowel-pin inserted in a felloe.

Figure 2 represents two felloes joined by myimproved-metal dowel-pin.

Figure 3 represents the dowel-pin detached.

Similar letters of reference indicate corresponding parts.

'This invention relates to a new and useful improvementin dowel-pins for fellies or felloes of wheels, and consists in forming it of a metal tube or thimble, which is inserted in the ends of two felloes, to'join them together, instead of the ordinary solid pin of wood or other material. I

The advantage of this mode of forming a dowel-pin is the increased strength it gives to the joint, by the preservation ofthe wood which enters the tube, and being held tight therein, prevents the ends of the felloes from splitting, to which accident they are liable with the ordinary solid wooden pin, with which the felloe depends entirely on the wood outside for its strength and integrity. 1

A A represent two felloes of a wheel, and

B a metal tubular dowel-pinto join them together.

In order to introduce the tubular dowel-pin into the ends of the felloes, they are bored out with a proper centre-bit, in rings or annular recesses, 11 a, fig. 1, corresponding to the diameter and thickness of the tube, as deep as may be necessary to receive one portion of the pin in one felloe, and one part in the other. as shown clearly in fig. 2. p

The round teams 0 0, left within the annular recesses a a, bored into the ends of the felloes, fill the tube B, and make a strong joint-that cannot split the tube, bind and hold the wood of each felloe, while, at the same time, they serve as dowel-pins to join the ends of the felloes together, which advantages of my improved tubular metal dowel-pin are obvious. 7

Having described my invention, I claim as new, and desire to secure by Letters Patent- A tubular metal felloe dowel-pin, employed substantially as herein described.
