IMPROVED HAND-TRUCK.

The Schedule referred to in these Lettera- Patent:A and making part of the name..

To all whom it may concern;

Be it known that I, HENRY C. INGRAHAM, of Tecumseh, in the eonntyof Lenawee, and State of Michigan, have invented a new and useful Improvement in Hand-Barrows; .and I do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification, in which- Y Figure l is a side View of the barrow as in use; Figure 2 is a top view; Figure 3 is a side View; and Figure 4 is a View of a pipe resting upon its support,

7 or table, in 'readiness to be removed,

The object of this invention is to provide means for removing undried drain-tile from the machine in which they are formed, without the hazardous necessity of handling them; and

,It consists of a kind of adjustable barrow, by means of which vthe pipes can be removed to the place for drying, without danger of injury.

A represents -the frame of the barrow, and

B represent-s the wheels, of which there are two.

C represents a bent axle', and y D, an arm upon each axle, extending at right angles thereto.

E is a' connecting-rod, one end of whichl is connected, by a pivot-joint, to the arm D, and the other end of the connecting-rod E is united, by means of a pivotjoint, to the lever F, as shown in iig. 3.

The lever F is pivoted to the frame A' at G, as Shown in iig. 1.

-H represents fingers or arms, that extend forward from the frame A, to which they are attached; and in the use of this machine, these fingers are thrust :forward beneath the board upon which the newlyformed tile rests, the lever F being elemted, as showni'n fig. 3, also shown by red lines in fig. l.

Now, bydepressing the lever F; as, shown in fig. l, the bent axle is partially rotated, and the wheels ac ing as a fulcrnrn, the fingers are elevated, andthe pipe can thus be transported to the place for dryi'ng,.and` g by again elevating the lever F, the load is deposited.

The axle-tree is secured to the vframe A by means of two springs, I, one only being shown in fig. 1. By thisfmeans the barrow is prevented from sudden concussions, or jarring, as the newly-formed tile is being moved.

Having thus described my invention,

What I desire vto secure by Letters Patent, is- 1. The bent axle O, connecting-rod E, and lever F, in combination with the frame A. l

2. The spring I, in combination with the axle-tree O and frane A, as shown and described. X

In testimony whereof, I havesigned my name to this specication, in the presence of two subscribing witnesses.

Witnesses: HENRY O. INGRAHAM.
