PEEL FOR HEATING-FURNACES.

SPECIFICATION forming part of Letters Patent No. 402,588, dated May 7, 1889.

Application filed March 24:, 1888. Serial No. 268,329- (No model.)

of Pennsylvania, have invented certain new and useful Improvements in Peels for Heat ing-Furnaces; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had'to the accompanying drawing, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to an apparatus intended more particularly to be used for-charging heating-furnaces with metallic piles, ingots, blooms, &c., and for" withdrawing the same.

It consists in a construction which permits the peel, whether light or loaded, to be suspended in equilibrium, if desired; also, in details of construction, as fully set forth and claimed herein.

The drawing shows a side elevation, partly in section, of my apparatus suspended from above the roof of a furnace to which it is supplying a pile of metal to be heated.

I-I represents an ordinary heating-furnace with charging-door H The pile L is shown in position on the blade J of the peel, ready to be lowered to the bottom H of the furnace. This blade, which may be eight inches wide, (more or less,) is rectangular in section, and is secured to the peel-bar J by pushing one end into a socket, J and pinning it, as shown, or in any equivalent manner which will permit the blade to be readily moved and replaced. The peel-bar J 'is provided at its opposite end with a toothed quadrant, J and is pivoted at A to the bent arm A, which rises vertically and then bends to about a right angle over the roof H of the furnace, while at the bottom it is bifurcated and bent at about right angles in the opposite direction, the peel-bar J, to which the blade is secured, being adapted to swing vertically in the bifurcated extension-arm A. A worm, K, on a vertical shaft, K, with hand-whee1 K is supported in the closed end of this extension-arm and adapted to. gear with the toothed quadrant J ,and the guide-handle B, with the usual cross-piece near its far end, is also securely fastened to the extension-arm A. A counterbalance-weight, D, is adj ustably supported on the horizontal slide-bar 0, projecting from the upper bend of the arm A. The latter is suspended at one of the points A about vertically above the center of pile L, to a swivel, E, adapted to run on an overhead track or crane-jib, G.

The operation of my apparatus is as followsi The peel when light may be balanced by adjusting the weight D so that the blade J will naturally hang in about a horizontal position, and as the center of load L is adapted to come about vertically under the point of suspension this equilibrium may be approximately maintained with any weight of pile. In order to raise or lower the blade J without changing the horizontal position of the guide-handle, the hand-wheel K may be turned in the proper direction, and the worm K, acting upon the toothed quadrant J will effect the desired object.

The steel blade J, which is exposed very frequently to the intense heat of the furnace, may be readily reversed or replaced without aflecting the remainder of the apparatus. The weight, being suspended in equilibrium, may be handled and guided with a much smaller force of men and with greater speed and safety than with a form of peel such as is commonly used, which requires a large force of men merely to balance the weight of the pile in transferring it to and from the furnace.

I do not wish to confine myself to the construction shown in the drawing, the gist of my invention consisting in movably suspending the peel, so that whether light or loaded it will be approximately in equilibrium, and in making the blade adjustable vertically independently of the guide-handle.

I am aware that Patent No. 134,151 shows a bent bar, by means of which the pivotal point of the peel is introduced into the furnace in charging. This, however, is not adapted to support the load in equilibrium, and I do not desire to claim such a construction.

What I desire to secure by Letters Patent are the following claims:

1. An apparatus for charging furnaces, con= sisting of a peel secured to a bent arm movably suspended at a point vertically above a weight on the peel-blade J, substantially as and for the purpose set forth.

2. An apparatus for charging furnaces, consisting of a peel secured to a bent arm movably suspended at a point vertically above a Weight on the peel-blade J, and a counterbalance, D, substantially as and for the purpose set forth.

3. The combination, with the movably-suspended bent arm A, having a guide-handle, of a blade, J, pivoted to said arm and adapted to be raised or lowered Without moving said arm, substantially as and for the purpose set forth.
