UNT-TEE STATES PATENT FFTCE.
HENRY UNDERIVOOD, OF NEW YORK, N. Y.
LAP-JOINT FOR BELTING.
Specification forming part of Letters Patent No. 19,318, dated February 9, 1858; Ressued January To all whom it may concern:
Be it known that I, HENRY UNDERWooD, of the city, county, and State of New York, have invented a new and useful Improvement in Forming Lap-Joints for Machine- Belting; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a front or face view of a joint constructed or formed according to my invent-ion. Fig. 2, is a longitudinal section of ditto. Fig. 3, is a detached view of one o-f the metal straps.
This invention is designed to prevent the ruiiling or turning up of the outer ends of the laps which is generally caused by the friction produced as the joint passes over pulleys, drums, &c., and also to prevent the cutting of the thin outer ends of the lap by the heads of the rivets in case the cement loses its adhesive property, or gives way, and the connection thereby formed solely by the rivets.
To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.
A, B, represent the two ends of a belt or two pieces of helting. rThe ends of these two parts are chamfered, or skived and cemented and lapped in the usual way, so that the parts A, B, at their junction will be of the same thickness as at other parts.
C, represent rivets of the usual form which pass through the chamfered ends and serve, in addition to the cement, to secure the central portion of the joint. The extreme ends of the chamfered or skived parts are secured firmly together by rivets straps is shown clearly in Fig. 3. By referring to Fig. 1, it will be seen that the rivets are placed transversely in rows of three each but they may be placed nearer each other if desired more rivets being used. The straps (L) in consequence of projecting over the ends of the laps protect their ends and pre-vent them from being turned up, they also in case the cement gives way or from any cause loses its adhesive property and the strength of the oint depends solely on the rivets, prevent the heads of the rivets from cutting through the laps. This cutting of the laps near their thin ends by the heads of the rivets generally occurs when the cement gives way, for when the belt is in use, the rivets owing to the strain to which the belt is subjected are canted or turned out of right angular positions relatively with the sides of the belt, and the heads of the rivets readily cut through the laps near `their outer ends on account of being quite thin at these parts. The straps (b) it will be seen prevent this as the heads are not allo-wed to come in contact with the belt at the outer ends of the laps and the straps also bind firmly the outer and inner ends of the laps together so that the thin outer edges of the same cannot be turned up, or parted from the inner Vand thicker ends. The improvement also allows of the ends of the laps being made thick or thin at pleasure without detriment to their strength and does not render cement absolutely necessary to make a strong durable oint. In case a belt is exposed to wet, the rivets alone may be used.
Having' thus described my invention what I claim as new and desire to secure by Letters Patent, isd
The straps (b) placed on the rivets a) which pass through the outer and inner ends of the laps or skived portion of the parts or ends A, B, o-f the belt as shown, so that the straps may project over the outer thin ends of the laps, substantially as and for the purpose as herein set forth.
