IMPROVEMENT IN WHIFPLE-TREE PLATE,

flI-lp Stlgrtult taunt it in llgtfit amen patent ant mating part at the arm.

TO- ALL WHOM IT MAY CONCERN:

.- Be it known that I, JAMES B. CLARK, of Plantsville, inthe county of Hartford, State of Connecticut, have,

invented a new and improved Whifile-Tree Plate; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being bad to the accompanying drawings,' making a part of this specification, in which- Figure 1 is a front elevation of my invention attached to the whifile-tree and cross-bar.

Figure 2 is a. section of the same. i Figure 3 shows the separate parts of my invention. :Similar letters oftreference indicate like parts. p My invention consists in .theuse or employment of three separate plates of cast metnl, the first provided with a shaft in its centre, to which the second is fitted, and hcldin its'place by the third,

A designates the first plate, B designates the shaft, and C the tenon on the end' of "the-shaft B.

The second plate, D, has a'bearing,-E, made to fit the shaft 13, also allarg er bearing, F, made to fit the edge of 'the third plate, G, while the centre of .the third pla'tdG fits the tenon G. 1 p

The first and second plates A and D are provided with arms 7 h 7:, in which are screw-holes, for fastening the plates to the cross-bar K and whiffle-tree L. One arm, it, on oacl1 p'lat e is turned or set atmight angle with the plates, in order that two screws can be placed in the bottom of the whifile-tree L, and two in the top of the cross-bar K, and one on the side of each, which secures the plates firmly in their places.

The shaft 13, tenon C, bearings E and F, and the third plate G, can be turned, milled, or finished in any proper manner.

When the parts are fitted, place the second plate D on the first plate A, with the shaft B in-the hearing E.

Next, place the third plate G in the bearing F, with the tenon C through its centre, and secure it in its place by rivets through the holes z. r i

'If desired, the tenon C and the centre of the third plate Gr might be threaded, 'and thus hold in its place the third plate G.

The tenon C might be made long enough to upset, and thus hold the'third plate-G in its place. T, in fig. 2, designates a hole, which is filled by the whiflie-itree bolt M in 1.

NN designate the rivets that hold the third plate G in its place The plates-thus held together "make an easy-working joint, and one perfectly secure of itself, without the aid of the whifile-tr'ee-holt 7 By my invention I produce a whiflile-tree plate with a large bearing,- holding the whifile-tree firm in its place, and not liable to rattle. If neatly fitted, dirt or sand cannot get into the bearings, causing them to wear out Should the Whittle-tree bolt M, accidentally or otherwise, he removed, the plate will hold the whiflle-tree in its place, and consequently is a safeguard against accidents. v

What I claim as new, and desire to secure by Letters Patent, is-- A whiflle-tree plate, with its shaft 13, tenon C, bearings E and F, and third plate G, all constructed. and

' Operating substantially as described,

. JAMES ,B. CLARK.
