DRAFT-EQULIZER.

SPECIFICATION forming part of Letters Patent No. 668,204. dated February 19, 1901.

1 Application led June 8, 1900.

`employed in connection with harvesters, harrows, and other farm machinery requiring three or more horses; and it consists in the construction, combination, and arrangement of parts, as hereinafter shown and described, and specifically pointed out in the claims.

In the drawings, Figure lisa plan view, and Fig. 2 is a front view, of the equalizer and the necessary doubletrees and singletrees connected in place upon a section of a drafttongue as arranged for a four-horse equalizer. Fig. 3 is an enlarged detail in perspective of the snpporting-lnacket for sustaining the equalizer mechanism and preventing it from sagging. Fig. 4 is an enlarged detail in section of the coupling mechanism between the draft-beam and the doubletrees.

A represents the draft-tongue of the vehicle to which the equalizer is to be applied and will be firmly fixed, so that it will not turn in its fastenings on the vehicle to which it is attached.

B is the main equalizer-beam, which eX- tends transversely of the tongue, as shown. Attached pivotally to the tongue bya kingbolt is a bracket, formed in two parts D D2, the ends of the two parts D' D2 neXt the tongue embracing the latter on both sides and secured thereto by the one common king-bolt h, as shown, which passes through both members of the bracket and also through the tongue. The beam Bis pivoted to the bracket at some distance from the end by a bolt D3, leaving a projecting end D4, which assists in supporting the beam and preventing it from sagging. An extended bearing is thus provided for the support of the beam, which greatly adds to the stability of the connection, while at the same time permitting the beam to freely swing horizontally upon its pivot D3.

E' is a doubletree, and E2 E3 two singletrees, connected to the doubletree in the ordinary manner by links a a2, while the double- Serial No. 19,618. (No model.)

tree is in turn connected to one end of the beam B by a longer link a3. E4 is another doubletree, and E5 Ei are two other singletrees, connected to the doubletree E4 by links CL4 a5.

E is a link having perforations cl' d2, one at each end, and another perforation d3 about one-third the length of the link.

F2 is a rod pivoted at one end of the pivotbolt D3 and at the other to the perforation d of the link F. E3 is another rod pivoted at one end to the perforation d3 of the link F' and pivoted by the other end to the end of beam B. The means by which the long link A0.3 and the rod F3 are connected to the beam B is of peculiar and novel construction, as shown, and consists of a clip bent into U form, as shown, with one short leg e' and a long leg e2, the short leg fitting in a cavity in the beam B and the longer leg passing through the beam and provided with a nut cs, as shown. By this means a simple clip is provided, by which the links and rods are rmly secured by one single nut to each clip.

The bracket, composed of the parts D', D2, and D4, forms a table-like platform for the support of the evener B, the said parts being pivoted together, as at D3. The platform prevents the evener from rubbing on the pole or tongue, and thereby greatly reduces the friction and prevents the wearing of the contiguous parts.

Having thus described my invention, what I claim as new is- 1. In a draft equalizer of the class described, the combination of the tongue, the transversely-arranged equalizer-beam situated on lines above the top of the tongue, the brace-rod hinged directly to the tongue and hinged to the central part of the transverse beam, the laterally-extending brace adapted to stay the beam and support it vertically and composed of the bar D2 pivoted to the under side of the tongue and the bar D pivoted to the upper side of the tongue and lconnected to the aforesaid part D2 and pivotally connected to the under side of the beam and extended longitudinally outward beyond the pivot, whereby the brace provides an expanded table-like support for the beam, substantially as set forth.

2. In a draft equalizer, of the class described, the combination of the tongue, the transversely-arranged equalizer-beam, abo've and extending across the tongue, the bar pivoted to the under side of the tongue and eX- tending laterally therefrom and upward, the bar D pivoted to the upper side of the tongue and bent or curved upward, and pivoted at.

D3 to the lower bar D2, and extended longitudinally outward beyond the pivot to form a table-like support for the equalizer-beam situated in a plane above the tongue and the attachments thereto, said pivot D8 being also 'connected with the equalizer-beam, whereby said bars D and D2 provide an expanded
