WHIFFLETREE.

SPECIFICATION forming part of Letters Fatent No. 496,608, dated May 2, 1893.

Application filed March 15, 1892. Serial No. 425,032. (No model.)

To allrwhom t may concern.

Be it known that I, NATHAN L. HOLMES, of Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in IVagon-Evener Connections; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has forits object to provide an improved connection between carriage poles and their eveners and it consists in the several features of construction and in the combinations of devices substantially as hereiuafter described and pointed out in the appended claims.

In the accompanying drawings: Figure l represents my invention in plan view. Fig. 2 is a vertical longitudinal section in the line Fig. 3 is a vertical section in the line 3 3 of Fig. 1, and Fig. 4: is a section of the evener on the line 4 4 of Fig. l, looking in the direction of the arrow.

A represents a carriage or Wagon -pole and B the evener.

C is the strap for supporting the upper end of the boltD which passes through the evener and pole in the axis of their pivotal connection. As .here shown the direct strain of draft is largely taken olf the bolt D by the familiar device of a circular boss e rising from the pole plate E into corresponding recess d formed in the pivot plate D which is fastened to the under side of the evener. cipal purpose of my invention I supplement these or other pivot devices by a short metal cross-bar F, centrally pivoted at f upon the pole A at the rear of the evener and parallel with it, the ends of the vibratory cross-bar F being connected with the evener on opposite sides of its axis D by means of the metal links G G which are pivoted both to the cross-bar and to the evener plate. The cross-bar F is preferably provided with bosses f at its ends which t into corresponding holes in the ends of the links G and take the strain i'mposed upon the cross-bar by the draft upon the evener. Desirably also the plate D is prolonged and provided with similar bosses cl fitted into holes in the front ends of the links For the prin-- The cross-bar F and the links G thus pivoted to each other, are held together by means of vertical bolts g having washers g and nuts g2, as shown, and the plateDand the said links are similarly held together by the bolts d2 passing through the evener and said bosses CZ and provided with washers cl3 and nuts d4.

The plate Dis shown as being still further extended outwardly and provided at its outer ends with upturned lianges D3 which rise at opposite sides of the evener in close contact therewith to give to said evener direct lateral support at a distance from its central pivot. The front flanges D3 are the ones more directly eifective to this end, but the rear [langes are desirable in order that said front llanges may at all times be held by their presence in close bearing contact with the evener.

In the construction described not only is the strain largely taken off the central pivot,

and particularly is the forwardly tippingv strain upon the evener taken from the pivot bolt D and strap C, but the lengthwise Itipping tendency of the evener is largely obviated and all the parts are held more perfectly in their original and proper positions with respect to each other. 1

The construction of the cross bar F of metal enables itto be made short and effective without being bungling or in the Way while the employment of metal links which are pivoted to the short metal bar F and the metal pivot plate D enables these parts as Wellas the bar F to be made so light as to be unobjec'- tionable either on account of their weight or of their appearance and at the same time durable and firm in their connections.

As a further improvement I have shown the strap iron (l provided with lateral projections or shoulders c arranged in position to be struck by the rear rounded ends of the links G or by the cross-bar F when the evener has been turned on its central pivot to a desired limit of motion.

I claim as my invention 1. The combination with a pole and an ICO 2. In combination with a pole, an evenerbar having a central pivotal connection With -the pole, and an evener-pl'ate secured to the between the pivot and the ends `of the bar,v

substantially as set forth.

3. The combination of a pole, an evener provided with a plate D', a cross-bar F centrally pivoted to the pole parallel with the evener, and links pivotally connecting the ends of said cross-bar With the plate D.

4:. The combination with the pole A, interfitting pivot plates D and E affixed respectively to the evener and pole,a bolt D holding the evener to the pole, a cross-bar F centrally pivoted to the pole, links G pivotally connecting the ends of the bar F with the plate D', and flanges D3 formed on the plate D and rising in contact with the front face of the evener.

5. In combination With the pole, the evener, the cross bar and the links connecting the cross-bar with the evener, an iron secured to the pole and provided with shoulders arranged in the path of one of the vibrating parts connected with the evener whereby the latter may be arrested at a desired limit of movement upon its pivot.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two Witnesses.

NATHAN L. HOLMES.
