METHOD` 0F JOINING DOFFER-RINGS FOR CARD-SETTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 254,651, dated March 7, 1882.

` Application tzlerd September 10, 1881. (No model.)

To all whom it may concern:

Be it known that l, JOHN J. HOEY, a citizen of Lawrence, residing at Lawrence, in the county of Essex and Stale of Massachusetts, have invented certain new and useful Improvements in the Method of Joining Dotfer- Rings for Card-Setting Machines; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which forni a part of this speciiication.

Figure l isa plan view of the back of a card or doer-ring at the joint.; Fig. 2, a longitudinal section with the teeth removed, showing the jointand the stitches; and Fig. 3 is'a longitudinal section, showing the teeth passing through thejoint.

' This invention relates to improvements in joining dolfer-rings for the card-setting'machine; and the novelty consists in the construction of the same, as will be hereinafter more fully set forth.

In the accompanying diawings, similar 1et ters of reference marked thereon indicate like parts of the invention.

AB represent the ends ofthe card-fillet, andto form the joint they are rst cut obliquely,

as shown in Fig. 1. The oblique ends are then beveled, as shown in Fig. 2, and joined by suitable cements, preferably flexible onessuch as are known under the general name of 35 rubber cements.7 The card-fillet is then stitched, as shown by C and D. This stitching adds materially to the strength of the joint, and at the same time does not interfere with its iiexibility. The card-fillet is then placed in a card-setting machine and the teeth inserted in the usual manner. The teeth, When passed through the joint, as shown in Fig. 3, give additional strength to it, and the whole, when completed, forms a joint as strong and at the same time as flexible as any other part JOHN J. HOEY.
