TIP-CARVT-OPEQRATINGI, DEVICE.

SPECIFICATION forming part of Letters Patent No. 524,787, dated August 21, 1894. Application filed February 5, 1894. Serial No. 499,120. (No model.)

skilled in the art to which this invention appertains to make and use the same.

This invention relates to an improvement in mechanism of the kind described in iny previous Letters Patent, No. 513,132; the object of my present invention being to provide,

in combination with a tip-cart holder and supporter, a lever appliance adapted for operating in conjunction with the notched supporter to aid the operator in easily tilting the cartbody when heavily loaded, as more fully hereinafter described.

In the drawings, Figure 1 is anoutline side view of a tip-cart showing my invention as applied thereto. Fig. 2 is a front view of the same. Fig. 3 is a plan view of the lifter and adjacent parts in detail, and Fig. 4 is a view of the lever-retaining clip.

Referring to parts, A indicates the axle; B the tongue; 0 the tilting cart-body pivoted at a to tip backward; D the upwardly projecting supporter pivoted to the tongue at c and having the series of upwardly directed teeth or notches cl along its edge adapted for engaging the body-iron or loop F that retains the adjustment of and is fixed to the front of the cart-body. g

G denotes the supporter-spring; I the looking device or slide-block adjustable on the bar D, and J the locking bolt for securing the slide at position of adjustment onthe bar by engagement with one of the holes m thereint All of the above named parts may be constructed as shown or as heretofore employed in my previous invention, set forth in the patent above mentioned; and need not be herein more particularly described in individual detail.

In accordance with my present invention I arrange at the front of the body a lifting handlever L in the following described manner? An'attaching piece or link P is securely connected to the body-iron F (or to the body frame adjacent thereto) at about three inches, more or less, from the bar D, and provided at its upper end with an eye P. In said eye is loosely connected, by a loop or equivalent joint, the end of the arm or lever. L which exwith an overhanging loop or edge 25 of suitable form and size for taking into or engaging with the several notches or teeth d of the supporter bar D- that acts as a fulcrum for the same. Said loop is preferably slightly curved,

as shown, to accommodate the swing of the parts when in use.

A retainirig clip R is attached to the upper part of the body front into which the arm of the lever L can be adjusted (see dotted lines D Fig. 2) and there retained out of the way of the holding devices when not required for use.

In the operation, the lever is brought down to working position, as in full lines Fig. 2. The operator then taking hold of the handle 71. raises the lever and hooks its edge or loop 25 into one of the ratchets d of the bar D; then by pressing down the long arm of the lever L the front end of the cart-body and load is lifted by the short arm and attaching piece P, the lever acting over the tooth of the bar D as a'fulcrum, thereby carrying the bodyironF upward along the bar D until it can be entered into a higher notch than it before occupied, where it will be readily engaged by permitting the backward swing of the supporter-bar; the loop t is then released from the notch 01 which it occupied, the handle of the lever raised, and the loop re-en gaged in a higher notch and the lifting operation, as above noted, is repeated elevating the body another notch, and so on by easy steps until the cart-body is tilted to a convenient height. The lever can then be swung up into the clip .R, and the body overturned therest of its distance, if desired, by a light push by the operator. By this mechanism a heavily loaded cart can be readily tilted or tipped, as required, by a single person and without great labor. The mechanism is simple and inex-r body; said lever adapted for operation in conjunction with the several teeth of said supporter as a fulcrum, substantially as and for the purposeset forth.

2. The combination with the tongue and wardly swinging support-bar pivoted to the tongue and provided with a series of ratchets .or notches along its edge, a body-iron fixed to the front end of the cart-body, adapted for engaging said notches, and a spring that normally swings said support-bar toward the cart-body, of a hand-lever its end loosely jointed by an attaching piece or link in connection with the body-iron, and having an edge or 100p for engaging with the notched support-bar, for the purposes set forth.

3. The lifterlever provided with an overhanging engaging loop, and having its longer end formed as a handle and its shorter end loosely connected by a suitable joint-piece with the body, and a lever-holding clip attached to the body-front, in combination with the tilting cart-body, the tongue, the notched supporting bar pivoted to the tongue, the support-bar spring, the body-iron and the holder adapted for sustaining the tilting body at position of adjustment, all substantially as shown and described. body in a tip-cart, and a backwardly and for- Witness my hand this 29th day of January, A.
