WHIFFLETREE.

'SPECIFICATION forming part of YLetters Patent No. 264,600, dated September 19, 1882,

Application filed April 21,1882. (No model.) i

To all whom it may concern:

Be it known that I, CHRISTIAN AMMARELL, a citizen of the United States, and a resident of Brooklyn, county of Kings, State of New York, have invented a new and useful Improvement in Whiftletrees, ot' which the following is al specification.

The object of this invention is to prevent the whiffletrees from moving or tipping in vertical planes.

The invention consists of novel devices for holding Whiftletrces in such positions that they can move only in horizontal planes and can.V not tip or move vertically to interfere with the horses legs.

Figure l is a plan of myimproved ivhiflietree. Fig. 2 is a sectional elevation of the same on line x Fig. l. Fig. 3 isa detailed plan view, showing the connecting-bar of a singletree inserted in the lugs of the doubletree-end iron. Fig. 4 is a side elevation of the same.

Similar letters of reference indicate corresponding parts. u V

In the drawings, A represents a double-tree, on the center and front ot' whichA is secured a metal plate, A', havin g a central verticallyformed eye, a, while on each end of said double'- tree A is secured an iron ring, B, having forward projecting perforated lugs b b, the hole in each upper lug being preferably square, as shown at c, to prevent the turning of the bolt therein. -This double-.tree A is passed through the fork B of' the tongue C, by which the device is designed to be attached to a car or other vehicle, and is secured therein by means ota bolt, D, that is passed down through the holes ff' in the fork B and the eye c of the plate A', the square shoulder d of the said bolt I) fitting in `the square hole fin the fork B and preventing said bolt D from turning.

It will he observed that t-he fork of the tongue O is deep enough from rear to front to permit of the free motion of the double-tree A in a horizontal plane, while it is too narrow in the other direction to permit of an appreciable motion of said tree in a vertical plane, which construction is obviously an important improvement over the ordinary whifietree devices that permit the trees to tip vertically.

The tongue-fork B' is extended forward in the form ot' a closed loop, E, that serves for the lfrom a car or other vehicle.

engagement therein of a car-hook`when the operator desiresto hold up the whiftletrees for the purpose of attaching or detaching them This closed loop E possesses great advantages over the hook commonly liXed on the front of the double-tree, because it offers no point for the accidental catching of the traces therein.

The singletrees F F are provided with end irons, G G, having forward projecting single lugs m and rings g g for attachment ot1 the traces. (Not shown.)

H is a iiat bar or link having one end fashioned into a screw threaded bolt, 7L, and a square shoulder is formed on said bar H, while in the other end of said bar H is an eye, k. This bar H has its screw-threaded end inserted through the center of a single-tree, F, with its shoulder l entered into a corresponding socket, m, in said tree, and then a nut, n, screwed on said screw-threaded end, holds the tree F, so that it cannot turn on said bar H. The opposite end ot' the bar H is held between the lugs b b of a double-tree-end iron, B, preferably by a square-shouldered bolt, I, that serves as apivot on which the single-tree F can move in a horizontal plane, while the engagement ofthe end of the bar H-between the lugs b b prevents any vertical motion of said tree F.

It 'will be seen, then, that this invention for restricting the motion of whiftletrees to horizontal planes is one of great importance in this class of devices.

I am aware of Patents Nos. 231,3S1,151,S04, and 130,217, and I do not claim the construction shown in either patent.

What I claim isv 1. The combination, with the double-tree A and the plate A', having a vertical tube or eye, a, ot' greater length than" the diameter of the double-tree, of the tongue G, provided with a loop, B', fitting closely' against the ends of the tube a, and having holes ff' to allow the passage of a bolt. through the loop and tube,

between said ears, and provided at the other end with :t shoulder, I, and bolt p,:1nd the whiflletree F, having a rectangular socket to receive the shoulder l, whereby said whiiletree is kept from falling,` or from turning, except in zn horizontal line, substantially ns described.

In testimony that I elninl the foregoing as my invention I have signed myname, in presence of two Witnesses, this 5th day of April, 1o i 1852.

CHRISTIAN AMMARELL.
