HAM E-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 434,967', dated August 26, 1890. Application led December 2, 1889.` Serial No. 332,276. (No model.)

To all whom it may concern:

Be it known that I, LOUIS WILDHAGEN, of Baileys Harbor, in the county of Door and State of Wisconsin, have invented a new and useful Improved llame-Fastener, of which the following is a full, clear, and exact description.

My invention is an improvement in the class of haine-fasteners which are adapted for adjustment in length and for detachable connection with the hames.

The features of the improvement are as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side view of the hame-fastener, with parts extended and attached to the lower ends of a pair of hames. Fig. 2 is a side view of the hams-fastener, an extensible portion being shown in dotted lines. Fig. 3 is a bottom plan view of the haine-fastener. Fig. 4 is an enlarged detached sectional view of a coupling-latch hook, duplicates of which are used to attach the ends of the device to a pair of hames. Fig. 5 is an enlarged perspective view of a detached coupling-latch hook, and Fig. 6 is a transverse section of the hainefastener, taken on the line 6 6 in Fig. 2.

One main portion of the hame-fastener consists of a shackle-bar A, which is made extensible by constructing it in two pieces a a. These pieces are similarly curved and adapted to have sliding connection with each other by providing the piece a with hooking or inwardly-inclined flanges a2 on its edges that are parallel, between which flanges the male portion a is slid, thus affording a dovetail engagement for these pieces that prevents lateral displacement. On the male piece'a a hook b is formed, which curves downwardly, having its terminal b enlarged and rounded to produce ears for a hinge-joint thereon, which ears are completed lby longitudinally slotting the hook through its body near the center of width.

A curved leaf-spring c is located in the slot of the hook b, conforming in shape thereto, one end being secured to the hook at c', the

` vent it from displacement.

other having engagement with the shoulder o2, formed on the latch-toe (l, which is pivoted at its end d to the ears b. The springt is expanded when introduced and bears forcibly upon the shoulder c2, which will rock the latch-toe d, so that an integral flange cl2 will engage its adjacent shoulder d3 with the upper surface of the hooks b n.

The portion a of the shackle-barA is perforated at e for the reception of the lockingpin e', which is diametrically enlarged at e2, forming a head therefor that seats upon the exterior surface of the portion a when the pin is depressed by contact therewith'of the leafspring e3, which is fastened by its opposite end to the shackle-bar, the upper or head portion e2 of the locking-pin e being slotted to receive the free end of the leaf-spring and pre- A guard-hook e4, which projects from the shackle-bar in alignment with the spring e2 near its free end, serves to limit the vertical movement of the locking-pin e', when it is disengaged from the Inale piece a of the shackle-bar.

A series of spaced indentations or socketholes e are formed in the male piece a of the shackle bar A, which are longitudinally aligned and adapted to register with thelocking-pin e when the two portions of the shackle-bar are adjusted so as to permit this. By the provision just described the length of the shackle-bar can be altered to suit the desired separation afforded to the lower ends of hames it connects.

On the female portion a of the shackle-bar Athe hook h is formed or secured near the end of the same oppositely to the guard-hook e4 that it is aligned with, its hook-lip h extending toward said guard-hook. (See Fig. l.)

The shoe-piece B, which forms the other main portion of the haine-fastener, consists of a piece channeled throughout its length, with the exception of a curved cap-plate i, that is integrally formed with the other part, which latter is an arched trunk having parallel walls that are shaped on their free edges to lie closely upon the portion a of the shacklebar A.

On the end of the shoe-piece B which is opposite to the cap-plate c' parallel lugs t" are produced on its walls by cutting away the yconnecting-arch that joins said walls and shaping the detached portions so as to aiord suitable supports for a transverse pin 7c, which can be seated in the hook h, as shown in Figs. 1 and 2.

A straddle-loop m is pivoted at its ends m to the side walls of the shoe-piece B, whichV tightly against the shackle-bar A.

Upon the loop m a coupling-latch hook n is loosely secured, so that it may vibrate freely thereon, said hook being constructed to duplicate in form and operation the hook b, whereby secure latching-connections are provided for the hame-fastener at each end thereof, which will automatically lock fast to the ordinary looped ends of harness-hames C when applied thereto in an obvious manner.

Owing to the peculiar manner of pivoting the straddle-loop m on the shoe-piece B and its position relatively to the point of hooked connection effected between the shoe-piece andshackle-barA, when the parts are adj usted as shown in Fig. 1, the hooks b and n being attached to the lower ends of the haines C, a swinging movement of the shoe-piece on its pin k will convert it into a lever having toggle-joints, thus enabling an operator to forcibly draw the separated hooked ends of the hame-fasten er toward each other until the edges of the shoe-piece and points of pivotal connection of the straddle-loop therewith are above the pivot-point k, which will lock the parts securely owing to the slightly-elastic nature of the collar upon which the haines are located.

Any desired adjustment for length may be eected by means of the extensible shacklebar A.

v The device is constructed mainly of malleable iron or low-grade steel, and can therefore be produced very cheaply.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a hame-fastener, the combination, with the shoe-piece B, the pivoted straddleloop m, its latch-hook n, the two sliding portions composing the body of the shackle-bar, the same having terminal hooks and one ot said portions provided with perforations e, of the locking-pin e', having an open slot in its head, and the leaf-spring e3, attached to one of the shackle-bars and its free end resting in the slot of said head, as shown and described.

2. In a haine-fastener, the combination, with the shoe-piece B, the pivoted straddleloop m, its latch-hook n, and the two sliding portions composing the body of the shacklebar, the saine having terminal hooks andv one of them provided with perforations e and the other with the guard-hook c4, located on itsl under side, of the locking-pin e, having a slotted head and arranged in vertical alignment with the aforesaid hook, and the leafspring e3, attached to one of the shackle-bars and its free end resting in the slot of said head, as shown and described.

3. In a hame-fastener, the combination,l

with an extensible shackle-bar composed of two sliding portions that can be locked at' different points by a pin-and-sooket connection, and a coupling-hook having a springactuated latch-toe, of an arched shoe-piece which is pivotally engaged with a projecting hook formed on the extensible shackle-bar, a straddle-loop pivoted at the ends of its limbs to the walls of the shoe-piece near one endy of said shoe-piece and out of line with its hooked connection on the straddle-bar, and a coupling-latch hook that mates the hook on the shackle-bar and is loosely attached to the cross-bar of the straddle-loop, substantially as set forth. y v

LOUIS WILDHAGEN.
