ADJUSTABLE HAME-DRAFT.

Specification of Letters Patent.

Patented Jan. 25, 1916.

To all whom it may concern:

Be it known that I, JAMES M. HUDSON, a citizen of the United States, residing at Blanchester, in the county of Clinton and State of Ohio, have invented new and useful Improvements. in Adjustable Hame- Drafts, of which the following is a specification.

My invention relates to adjustable drafthames, its object being to produce a cheap, strong and durable connection for the tug link, whereby the same may be readily adjusted to different draft positions on the hame.

To this end, it consists in a hame connection embodying a bar or staple for the engagement of the tug link, projected downwardly at each end to pass through and engage the device with the hame; and, united therewith, an intervening trough-shaped structure formed by corresponding ribs diverging outwardly and downwardly at both sides and merging in a rectangular annulus constituting the base edge of an elongated inverted trough-shaped structure which rests in contact with the hame. There is thus formed a truss support at each side of the staple, one in compression and one in elongation, which add greatly to the resisting strength of the bar and permanency of the structure. The tug link is preferably U-shaped, with the terminals bent to hookform to pass between the side ribs and engage over the bar or staple.

It consists further in the combination with the hollow structure thus described of an elongated strip of resilient metal curved or bent longitudinally along its center line to a V-shaped or curved cross section, placed within the trough-shaped structure, and retained therein without fastening, and bearing upwardly against the hooks of the tug link when engaged on the bar or staple, and preventing displacement until sufficient force is applied to turn the link over to be taken out and replaced elsewhere.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my improved fastening complete showing the parts detached; Fig. 2 is a side elevation of the device complete in position; Figs. 3 and 4L are opposite end views; and Fig. 5 is cross section showing the tug link in position engaged in the fastening device.

Referring now to the drawings, A designates the device as a whole adapted to be rigidly secured to the hame H by projections a (at the lower end) and a (at the upper end) of the device,these being extending through the hame and upset at their extremities as rivets.

The device A consists of a bar or staple a extended transversely at its ends by the terminal projections a a Between the two terminals, the bar a is flanked by downwardly and outwardly inclined sides or Webs a pierced by apertures a at regular intervals to admit the engaging hook or books of a tug link L, as in Fig. 5. The inclined sides merge respectively in a rectangular base wall constituting a continuous lower edge of the structure, designed to rest at the bottom at all points upon the face of the hame as in Figs. 2 and 5, being held thereto by the terminal extensions a a of the bar (4. Thus the bar a with its inclined sides (0 connected across at the ends, forms an inverted trough-like structure in which the sides constitute supporting and strengthening webs adding very greatly to the resisting power of the bar or staple (1 against the side stresses of draft of the tug link L, while at the same time the apertures a reduce the quantity and weight of metal employed without diminution of strength. The series of apertures is to enable adjustments of the tug link L upwardly or clownwardly as may be required. This is done by turning the link over to a position opposite that shown in Fig. 5, and pushing it out of connection with the bar a and reengaging it by the same manipulation reversed in the desired new relation with the bar through the appropriate openings a In order to assist in holding the link against displacement when in position, I employ a yielding loose strip of sheet metal B, bent up to a V or inverted U cross section, laid upon the face of the hame within the hollow of the device A without fastening. It extends approximately from end to end of the structure, and bears upwardly against the hook or hooks of the tug link L and is under slight compression when the tug link is in place.

The construction, as will be seen, is exceedingly simple, light in a Weight, exceedingly strong in resisting power for its intended use, and is also economical in 00st a member comprising a longitudinally-extending bar and Webs diverging therefrom and connected to each other at opposite ends, said member being rigid With pr0jections for fastening the member to the hames, the divergent sides of said member being perforated in alinement for the reception and attachment of a link in adjusted pcsitions, and a strip of resilient material "(if substantially arched form in cross section adaptedto seat on the 'hainesand to be confined ,in the housing formed between the inner Walls of the divergent sides and; the closed ends of said member.

In testimony whereof I have hereunto set 5 nesses 7 JAMES M.' HUDSON. lVitnesses:
