ROAD-CART.

SPECIFICATION forming part of Letters Patent No. 439,541, dated October 28, 1890.

Application filed June 2, 1890. Serial No. 354,037. (No model.)

To all whom it may concern:

Be it known that I, OTTO L. MUENCH, a citizen of the United States, residing in the town of Washington,in the county of Franklin, in the State of Missouri, have invented a new and useful Improvement in Road-Carts, of which the following is a specification.

My invention relates to roadcarts; and it consists of the arrangement and combination to of parts hereinafter described and claimed.

My object is to provide against and eliminate the horse motion usual in carts in a simple, durable, and cheap manner. I attain this object by the mechanism illustrated in I5 the accompanying drawings, in which- Figure l is a side elevation of a cart em bodying my improvement. Fig. 2 is a perspective view of that part of the t-hillcontaining my invention. Fig. 3 is a transverse longitudinal section of the same, showing the thill at rest. Fig. 4c is the same section showing the thill depressed at the joint.

A is the front section of a thill of a roadcart, and B is the rear section of the same.

a The joined ends of each member are cut on an angle, as shown, the purpose being to thus form a stop against the downward thrust of the member A. The member L is provided with two side pieces of metal B and B which pieces are rigidly secured to the part B on its respective sides and are extended forward and parallel therewith. These two side pieces are joined at or near the front ends by a connecting-piece of metal Z). The purpose of this connection is to strengthen the side pieces 3 B and to furnisha stop to resist the too-far-downward thrust of the member A. These side pieces B and B are provided near their front ends with a pivotal connection A, which in the drawings consists of an ordinary bolt passing through the metal pieces B I) tightly, so as not to move therein, and loosely through the wooden. member A, so that all movement will be confined to the bolt in the wooden member A, thus avoiding all noise in the operation of the parts.

On top of the member A near the end is secured by bolts or otherwise a stop a, having a jaw a bent up from a shoulder a and projecting beyond the end of the member A and extending over the memberB, and adapted to engage the member B as the front free end of the member A moves up.

S is a spring secured to the bottom of the member B and extending forward and approximately parallel with it and terminates in a free end 8, which is adapted to engage the lower side of the rear end of the member A and to move thereon in action. The function of this spring is to resist the downward pressure of the rear end of the member A, and thus tend to keep the thill straight, but allow it to yield to the movement of the horse in action. The contact of the free end of the spring S with the wood portion of the thill, instead of being hung in a stirrup, prevents any rattle or noise of the parts, which is a great advantage; also, by dispensing with the stirrup connection of the free end of the spring with the thill I make a neat job and a joint that will not engage the switch of the horse, as well as avoid noise.

d is another hole, provided for the insertion of a second bolt, which can be done if at any time it is desirable to make the thill rigid from end to end, which is often desired when it is desired to carry an unbalanced load on the cart and retain it in its normal position. The hole (I can also be used to change both, and thereby regulate tension of spring S.

There are many advantages resulting from this form of construction of the joint of the thill over others. Itis cheap in construction, having but few parts. It is as strong as though the shaft were made in but one piece, by reason of the side pieces. It is noiselessin its operation, having no metal working on metal or loose joints or link-connection. It is readily disconnected in case of shipment, thus enabling the manufacturer to pack many more in a car than can be done with others. Its parts are all smooth and will not engage the switch of the horse. Its mode of operation is simple and needs no description of it.

Now, what I claim, and for which I ask Letters Patent of the United States to be granted to me, is-

1. In a road-cart, thethill consisting of two members, a front and a rear member, two side pieces rigidly connected to the sides of the one and embracing said sides and extending laterally along the sides of. the other member and pivotally connected thereto, said pieces being connected together at their pivotal ends, a stop arranged on said side pieces, serving to arrest the movement of themembers on each other, a spring arranged on the under side of the members and rigidly connected to that member to which said side pieces are rigidly connected at one of its ends and having the other end free to act on the moving end of the other member, and a stop arranged on the end of that member which is pivotally connected to the side pieces and adapted to engage the end'of the member which is rigidly connected to said side pieces, substantially as above described, and for the purposes set forth.

other by the other end, substantially as de- 0 scribed, and for the purposes set forth.

OTTO L. MUENCH.
