SPECIFICATION forming part of Letters Patent No. 367,206, dated July 26, 185.7,

Application filed Febluary 16, 18:7. Serial No. 227,773. (No model.)

To aZZ whom, it may concern.-

Be it known that I, ADOLPH HAMPE, of the city, county, and State of New York,ha've invented a new and useful Fastening Attachment for Chains; and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which Figure 1 is a sectional elevation of a portion of awindow sash andcasing, illustrating the application of my invention in the suspension of the sash-weight by means of a chain made of flat links. Fig. 2 is a similar detached section, on an enlarged scale, through the stopblock set in the window-sash to confine the innerend of the sash-chain. Fig. 3 isa similar enlarged detached section through the hook at the outer end of the sash-chain. Fig. 4 illustrates in side elevation and transverse section the application of my invention in'con'nection with a chain made of bent loops without weldlVly inventionrelates to a device for readily attaching the end of a chain Whose links are enlarged at each end to a hook, a stop-block, or other object.

It consists of the combination, with the outermost link of the chain, of a key formed with an inwardly enlarged slot or recess inone end adapted to embrace closely the swelling or enlarged portion of the terminal link, and which is adapted to fit within anaperture or seat formed to embrace it in a blockor hook or other object to which it is desired to attach the chain. Preferably the key is made tapering to fit into a tapering seat.

In the accompanying drawings, A represents a chain formed in the customary manner of flat links enlarged at each end, and strung together upon transverse pins or rivets; B, a metallic block or key, preferably made tapering, having an inwardly-enlarged transverse slot or recess, 0, formed in its upper or narrow end, and which extends inwardly to or beyond the center of the key in such form and of such dimensions as to be adapted to em brace closely one of the enlarged ends of the fiat link or links D at the end of the chain, as is clearly shown in Figs. 2, 3, and 4 of the drawings.

By means of the transverse slot or recess 0 the block or key B may be readily slipped on or off of the end link, D, of the chain, and will form a dovetailed joint therewith, which will prevent the separation of the chain from the key by any longitudinal tension thereon, such a separation being permitted only by slipping them apart laterally. hen the tapering key is thus adjusted upon the end of the chain, the chain may be readily secured to a head, E, either detached and adapted to fit into a recess in a window-sash, F, (see Figs. 1 and 2,) or formed integrally with a hook, G, or other object, as shown in Fig. 3, by forming in said head E a counterpart tapering opening, into which the key maybe readily inserted to seat itself, as shown in Figs. 2 and 3.

When the key-block is to be used with a chain whose links are formed of bent loops, as

shown in Fig. 4, a short transverse pin, G, is inserted in the eye of the outer loop, D, to be embraced by the key, so as to prevent the loop from collapsing and slipping out through the contracted outer end of the recess in the key-block.

In the use of my improved chain coupling or fastening-in securing the weights of windowsashes, the chain carried over the pulley H,

Fig. 1, is carried at one end in the usualmanner through the opening K, communicating with a recess, L, in the edge of the sash, and then passed through the tapering opening formed in a stop block or head, E, far enough to permit the, terminal link D to be slipped into the inwardly-enlarged recess in the tapering key B. The outer enlarged portion of the link D passes into the counterpart inner enlarged portion of the recess 0 in the key B, leaving the remainder of the link to project out from the narrow end of the key, as shown in Fig. 2. The tapering key B is then drawn back with the chain into the tapering opening in the stop block or head E, and this block is then drawn with the chain into the recess L in the edge of the sash, into which it fits closely, as shown in Fig. 1. The opposite end of the chain is in like manner drawn out through a tapering opening in the head of a hook, M, and after a tapering key, B, has been fitted, in manner as described, upon its terminal link D the link and attached key are drawn back into the opening in the hook, and the key,

wedging therein, securely fastens the chain thereto.

It is evident that by means of a tapering key thus fitted upon the terminal link of a chain,

A, the chain may be readily and very securely attached to any desired object having a counterpart tapering opening or seat formed therein to receive the key, in manner as described.

I claim as my inve11tion-- 1. The combination of a tapering key-block formed with an inwardly enlarged recess in its narrow end with the terminal link of a chain fitting within said recess, substantially in the manner and for the purpose herein set forth.

2. The combination, with. a head having a suitable key-seat formed therein, of a counterpart key-block adapted to fit into said seat, and formed with an inwardly-enlarged recess in one end adapted to embrace the enlarged end of the terminal link of a chain, substantially in the manner and for the purpose herein set forth.

' In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ADOLP H HAMPE.
