HAME FOR HARNESS.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Original application filed April 7 1902, Serial No. 101,646. Divided and this application filed October 8, 1904. Serial No. 227,712-

To all whom it may concern.-

Be it known that I, IVERT LARSEN, a citizen of the United States, and a resident of Chicago,

in the county of Cook and State of Illinois,

have invented certain new and useful Improvements in Hames for Harness; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. 4

This invention relates to improvements in hames for harness designed more especially for use by fire departments, in which use it is necessary that the parts of thehameshall be reliably held in proper adjustment or position, so that they may be used on short notice.

The invention relates more specifically to an improved tug-attaching loop and eye by which the tugs or traces are attached to the hames; and the object of the invention is to provide a combination of these parts of a harness whereby the eye to which the tugs are attached are held in proper relation to the tug-loop to form an adjustable connection of the eye with the tug-loop, to provide a durable structure of said parts, and to provide means whereby the eye may be readily removed from the loop.

The invention herein set forth and claimed is disclosed in my prior application for United States Letters Patent, filed April 7, 1902, Serial No. 101,6&6, of which this application is a division.

In the drawings, Figure 1 is a front elevation of a collar, showing a set of hames thereon provided with tug eyes and loops made in accordance with my invention, showing the tugeyes in two positions. thereon. Fig. 2 is a sectional view of the hame, tug loop and eye, showing the manner of connecting the tugeye with the loop. Fig. 3 illustrates the manner of removing the tug-eye from its link by which it is connected with the tug-loop. Fig. 4 is a partially plan view and partially crosssectional view of the parts shown in Fig. 2. Fig. 5 is a view, partially in perspective, illustrating the manner of detaching the tug-eye hame.

from its connecting-link. Fig. 6 is a fragmentary side elevation of one of the bolts and its washer forming part of the tug-loop of the Fig. 7 is a sectional view of said bolt and washer.

As shown in the drawings, and referring more specifically to Fig. l, A designates a collar of that type which is separated at its ower or throat end and the side members of which are flexibly joined at the upper or wither end of the collar, whereby the said side members may be separated and moved together for the purpose of applying the collar to and removing the same from a horse.

BB designate the hames, which are hinged at their upper ends above the wither end of the collar and are provided with locking devices at their lower ends, by which the collar is held in place and locked. The hinge at the upper ends of the hames for connecting the same together in the manner described consists, as herein shown, of a bolt or pintle 6, that extends through registering apertures in the ends of the hames, one of the hames being forked and receiving between its forked arms the end of the other hame in the general manner shown in my aforesaid application. The locking device for the hames, at the lower ends thereof, consists of a locking-bolt B on the lower end of one of the hames, which enters and is locked in the socketed end B of the lower end of the other hame. Inasmuch as the means for hinging the hames and the means for connecting or locking the same at their lower ends constitutes no part of the present invention, the said parts or the construction of the hames are not illustrated in detail nor fully described.

Each of the hames is provided with a traceconnecting loop, (indicated as a whole by E on Fig. l of the drawings.) The traces or lugs of the harness are not connected directly with said loops, but are connected with trace-eyes (indicated as a whole byF in said Fig. 1,)and which latter are loosely connected with the loops E, through the medium of intermediate links G. The detail construction of thesev parts are shown more clearly in Figs. 2 to 7, inclusive, and are made as follows:

The loop E of each hame consists of two bolts E E, which extend transversely through the hame and are shown as riveted thereto at their inner ends. Said bolts are provided at their outer ends with enlargements or heads 6, which are apertured for the passage of vertical bolts E each extending freely through one of said heads and having screw-threaded connection at its lower screw-threaded end with the other. head, as shown in Fig. 2. The parts of the bolts E which project laterally from the hame constitute the top and bottom portions of the loop and the bolt E the vertical side portion thereof.

The links G are provided at one end with IIO hubs or sleeves G, which are apertured and through which the bolts E extend, and said links are closed or looped at the other end thereof to receive and retain the tug-eye F. The hub or sleeve G of each link Gr is made shorter than the distance between the upper and lower end portions of the loop E, and the space between said end portion beyond that required for the bearing part or hub G of the link is occupied by short filling-sleeves e e. Said filling-sleeves e afford means for adjusting the vertical position of the link G, and consequently that of the eye F and the tug attached thereto, with respect to the loop E. If, for instance, the sleeves be placed one on each side of the link, as shown in Fig. 1, the pull or draft of the connected tug is brought centrally on the loop. If, on the other hand, both of said filling-sleeves be placed between said link and one end of the loop, Fig. 2, the part of the loop receiving the pulling strain of the tug is raised or lowered, depending upon which side of the link said sleeves are placed. In this manner the application of the pulling strain on the shoulders of the horse may be varied to suit each particular case, such adjustment being required when the sections of the hames are adjusted endwise in the manner set forth in my aforesaid application to fit the particular collar on which the hames are used.

The eye F consists of a cast-metal body comprising an inner intermediate curved portion f and two parallel arms f and a bolt F, which extends through said arms and closes the end of the eye. Said bolt F passes loosely through one arm of the eye and has screwthreaded engagement with the other arm, as herein shown. To said bolt the tug or trace of the harness is adapted to be attached. Preferably the bolt is surrounded by an antifriction-roller F (shown in Fig. 2) to prevent undue chaifing and wearing of the tug.

The inner margin of the curved intermediate portion of the body is provided with a recess, the outer part of which is bounded by two projections f f which extend toward each other in the manner to form between the same the curved recess (indicated at F Fig. 3) to receive the outer looped end of the link G. The outer looped end of thelink is made of a greater diameter than the distance between its projectionsf referred to, so that when the eye occupies the outer part of the link, as shown in Fig. 2, (this being the normal position of the eye when a pulling strain is exerted on the parts or when the eye is free to hang downwardly,) the eye cannot be twisted out of proper relation with respect to the link. The inner parts of the arms of the link, however, near the sleeve or hub G are made vertically thinner than the outer parts thereof, as shown in Figs. 3, 4C, and 5, so that when said eye is shifted to the inner end of the link and is turned into a nearly vertical position, shown in Fig. 3, the recess F of the eye may be slipped readily over the thinner part of the link to permit said eye to occupy the position shown at the right side of Fig. 1. When the eye is in this position, it may be entirely detached from the link by removing the tugbolt F.

The advantage of this construction is that in case it is desired to send a tug to a repair-shop or it becomes necessary for any other purpose to remove the tug from the set of harness it is not necessary to remove the entire hame from the collar, together with the tug, but the the eye F may be readily removed in the manner just described, and it is the only part required to be detached from the harness with the tug. The usual construction of the eye while permitting such ready detachment from the hame prevents the eye from becoming de tachably twisted while the harness is hanging and insures that the parts shall be in proper position for instant use..

The bolts Eof the trace-loops are provided with washers E, which fit between the heads a and the harness. Said washers are shaped on their inner sides to conform with the curved surfaces of the hames. Said hames are not only transversely curved at the points through which the bolts extend, but are curved longitudinally, so that it is necessary in order to provide a perfect fit between the washers and the hames that the inner surfaces of said hames be not only concaved to fit the 'cylindric surfaces of the hames, but also slightly concaved to correspond with the longitudinal curvature of the hames. By reason of this double concavity of the washers said washers cannot conveniently be made an integral part of the flange of the bolt, as could be done if the hames at this part were straight, because of the difliculty in casting, and for this reason the washers are made a separate part of the bolts and applied thereto before said bolts are inserted into place.

A further advantage of connecting the eye F with the loop E in the manner stated is that the eye is free to swing upwardly or downwardly on the link when a pulling stress is exerted thereon, so that the traces are always parallel and are pulling against the entire length of the sleeves F or the bolts F of the eyes, notwithstanding whether or not the horse is standing above or below the level of the whiffletrees of the vehicle. There is therefore no sidewise pull of the traces relatively to the eye, tending to wear the traces by contact with the upper or lower arms of the eyes.

It is obvious that certain changes may be made in the structural details of my improvements without departing from the spirit of the invention, and I do not wish to be limited to such details except as hereinafter made the subject of specific claims.

I claim as my invention 1. The combination of a hame, a tug-attaching loop, a link hinged thereto, and a tug-eye loosely connected with said link, said eye consisting of a body part embracing a central curved portion and two parallel arms and a bolt extending detachably between and connecting said arms of the eye and to which the tug is directly attached, said central part or body of the eye being provided with a recess which receives the body of the link, and is made of such size as to prevent detachment of the link from the recess when engaged with the outer end of the link, and said link being made thin at its inner end to permit said recess to pass thereover when the eye is shifted to the inner end of the link.

2. The combination with a rounded and longitudinally-curved hame, of a tug-attaching loop comprising two bolts which extend transversely through and are attached to said hames in the part thereof which is longitudinally curved. the heads of the outer end of said bolts being apertured, a vertical bolt extending through said apertures and forming the oute end of the loop, and washers on said transverse bolt between said head and hames, said washers being concavedto fit the rounded contour of the hame and also concave to fit the longitudinal curvature thereof.

In testimony that I claim the foregoing as my invention I aflix my signature, in presence of two witnesses, this 30th day of September,

IVERT LARSEN. Witnesses:
