CLAMPING AND ATTACHING DEVICE- SPECIFIGATION forming part of Letters Patent No. 784,654, dated March 14, 1905.

Application filed August 26, 1904. Serial No. 222,248.

To all whom it may concern.-

Be it known that I, THIES BIEL, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New J ersey, have invented new and useful Improvements in Clamping and Attaching Devices, of which the following is a specification.

This invention relates to a clamping and attaching device for ropes, cables, and the like.

The object of my invention is to provide a clamping device of simple construction which can be quickly applied to ropes or cables in various articles of manufacture, such as lifesaving nets and rope ladders, and having means for attaching the hook of a spring or rod or other device.

The matter constituting my invention herein will be set forth in the claims.

The details of construction of my improved clamping and attaching device and certain applications thereof are illustrated in the accompanying drawings, in which- Figure 1 represents a plan view of part of a life-saving net, showing my device applied thereto. Fig. 2 represents a transverse section of the device and a rope, on enlarged scale. Fig. 3 represents a face View of one of the curved clamp-plates. Fig. 4 represents a front view of part of a rope ladder having my device applied thereto.

My clamping and attaching device A is constructed of two clamp-plates B and B, which are preferably elliptical in outline and curved to an approximately semicircular form, as shown in Figs. 2 and 3. The plate B is provided with a circular opening 6 and the plate B with an elongated opening or slot Z), which is preferably placed transversely, as shown. The securing and attaching bolt C is made with a screw-threaded end 0 and with an eye or loop 0 at the other end for engaging with the hook of a spring or rod or other part to be attached to the clamp.

In applying the device to a rope the curved plates B and B are placed opposite one another on the rope X. Then the rope is pierced by a sharp instrument passed through the openings 6 Z) and then the bolt C is inserted and the nut a screwed onto the end 0 till the loop 0 is drawn partly into the slot 6, preventing the bolt from turning, and the plates B B tightly drawn together and clamped upon the rope. The strands of the rope will be compressed upon and around the bolt (1, so that it cannot slip lengthwise. The slot 6 serves not only to prevent the bolt from turning when the nut is tightly turned up, but by engaging the end of the loop prevents it from being bent outward and opened by a strain thereon.

The device is simple and inexpensive in construction, easy of application, and very effective in operation. When the device is applied in pairs to opposite ropes, the eyes or loops 0' may be engaged by the hooks of connecting springs or rods, as illustrated in Figs. 1 and 4. The well-known life-saving net 1), having the usual border-rope (Z and outer hand-rope 0, may have my clamp A applied to the ropes (Z and c, with the loops 0 inward and engaged by the hook ends of the connecting-springs f. Evidently the connections will be in the nature of universal joints, as in the old and well-known coiled-spring connections of bed-bottoms, permitting the desired freedom of movement of the parts.

In the construction of rope ladders G, Fig. 4, the opposite ropes g g are conveniently connected by means of my clamps A secured at opposite points on the ropes, and the loops 0, engaged by hooks at the ends of the connecting-rods it. Numerous other applications of my clamping and attaching device will be found in various articles of manufacture.

I do not claim a fire-escape net having a continuous rope edge, a continuous rope surrounding it, and interposed spiral springs connecting them, as such construction is described and shown in a paient to Henry, dated July 10, 1877, nor do I claim the universaljoint connections between the ends of the springs and the connected ropes, as suchconnections are old and common at the ends of spiral springs in bed-bottoms and other articles of manufacture.

Having thus fully described my invention,

a bolt therefor having at one end a loop and at the other end a screw-thread and nut, the opening in one plate being adapted to engage said loop to prevent the bolt from turning, 5 substantially as described.

In testimony whereof I atfix my signature in presence of two subscribing witnesses.

THIES BIEL. Witnesses:
