' UNITED STATES PATENT OFFICE.
WALLACE TYLER, OF CHICAGO, ILLINOIS, ASSIGNOR TO LILLIAN M. MITCHELL,
OF SAME PLACE.
BELL-CORD ATTACHMENT.
SPECIFICATION forming part of Letters Patent No. 437,062, dated September 23,1890.
' Application filed May 22, 1890. serial No. 352,756. (No model.)
To aZZywhom it may concern:
Be it known that I, WALLACE TYLER, of Chicago, in the county of Cook and State of Illinois, have invented a new and usefulBell- Cord Attachment, of which the following is a full, clear, and exact description.
It is desirable in the attachment of the separate portions of a bell-cord coupling that the duplicate pieces of said coupling should be so secured to the ends of the cord as to permit their withdrawal from the coupling-sections in case the train of cars is separated accidentally, and thus prevent a rupture of the strands of the cord.
The object of this invention is to provide a simple and convenient means for the speedy attachment of a bell-cord by its ends to coupling-sections, whereby the cord ends Will be held sufficiently secure for legitimate use,but which will permit the removal of the cord ends from the coupling in case the cord is subj octed to an abnormal strain.
To this end myinvention consists in certain features of construction and combination of parts, as will be hereinafter described, and indicated in the claim.
Referenceis to be made to the accompanying I drawings, forming a portion of this specification, in which similar letters of reference indicate corresponding parts in all of the figures.
Figure 1 is a side view of one coupling-section containing the improvement. Fig. 2 is a side view of one coupling-piece, partly in section, showing a rope in coupled connection therewith. Fig. 3 represents a novel and principal feature of the invention detached from the coupling-hook; and Fig. 4 is an end View of the piece shown in Fig. 3, viewed in the direction of the arrow in said figure.
The cord-coupling consists of two portions that are of similar form. Hence but one section of the coupling is shown in the drawings.
A shell of metal A is provided, which terminates at one end in a hook B, of the usual form, employed to connect the two sections of an ordinarybell-cord coupling. The shellA 1s axially apertured a proper depth for the 1ntroduction of the rope-clamp O, and is lnternally threaded to facilitate the operation of the said clamp.
As represented in Figs. 3 and 4, the ropeclamp 0 consists of two limbs a a, which are threaded on their exterior to engage the threaded shell A. Said limbs are held normally divergent by their connection at opposite points to the ferrule b. The free ends a of the rope-clamp C are each furnished with a semicircular flange of similar shape, these flanges when compressed together forming a sectional collar or ring. The interior surface of the curved flanges c is flared outwardly to facilitate theintroduction of the end of thebellcord D, which should fit the interior of the ferrule b, it being of advantage in the connection of the cord with the coupling-section that the end of the cord be forcedthrough the ferrule, as shown in Fig. 2. There are shoulders e formed on the projecting ends of the curved flanges c, which are essential to effect a proper attachment of the cord to the coupling-section.
In making an attachment of the cord D to the coupling section or shellA the rope-clamp Cis forced upon the cord end, as shown in Fig. 2, and the clamp inserted Within the shell A by rotating the latter as a nut upon the limbs a a, where they are integrally joined to the ferrule 19.
The progressive movement of the ropeolamp Within the shell A embeds the limbs a into the body of the cord end D, thus flattening it and spreading the fibrous material laterally, as represented in .Fig. 2, which will cause the projected material to interlock with the shoulders e, and thus retain the cord ends sufficiently stable within the shells A to hold the series of connected bellcord pieces intact under ordinary strains incidental to its legitimate use.
When by accident to a car-train or from other causes the bell-cord is subjected to a strain which might tear it apart and render it unsightly if knotted together where broken, such a contingency is avoided by the slipping separation of one cord end from the couplingsection it is connected to, which separation can be quickly repaired by a reconnection of the rope or 00rd end with the rope-clamp and secured to a ferrule and each provided with shell, as has been explained. a semicircular flange at its free end, substan- IO Having thus fully described my invention, iially as herein shown and described. I claim as new and desire to secure by Letters WALLACE TYLER. 5 Patent- Witnesses:
In abell-cord attachment, the combination, CHARLES R. MCOABE, with an internally-threaded shell, of a clamp SAMUEL B. COULTER, consisting of two exteriorly-threaded limbs EUGENE W. SMITH.
