UNITED STATES PATENT OFFICE.

ISRAEL ERIcKsoN, or WHITEHALL, MICHIGAN.

FURNACE-FEEDER.

SPEIFICATION forming part of Letters Patent No. 243,694, dated July 5, 1881.

Application filed March 23, 1881.

To all whom it may concern Be it known that I, ISRAEL ERIcKsoN, a citizen of the United States,residing atWhitehall, in the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Furnace-Feeders; and I do hereby 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 drawings, and to letters or figures of reference marked thereon, which form a part of this specification, and in which Figure 1 is a side elevation of my improved fuel feeder and stirrer for furnaces. Fig. 2 is a section thereof, taken under and in the direction of the inclination of the chute. Fig. 3 is a rear elevation of the carriage of the chute, and Fig. 4 is a View showing the front or door end of the furnace.

This invention has relation to improvements in means for feeding fuel into furnaces particularly, and at the same time stirring the tire, having for its object the thorough feeding and consumption of the fuel; and it consists of the combination and arrangement of certain parts, substantially as hereinafter more fully set forth and claimed.

Referring to the accompanying drawings, which show the preferred form of carrying out the objects of my invention, though the details of construction may be modified, A A

. mark parallel horizontal ways, with their forward ends fastened to or supported against the front of thefurnace and arranged directly upon opposite sides of the doorway, the door being hung to swingvertically and closeimmediately after feeding the fuel into the furnace. The ways are supported at their rear ends in any suitable manner upon uprights of wood or pillars of brick, stone, or masonry. A bottom, a, is provided to the ways A, extending from the front end of the furnace to about midway the length of the ways, for the fuel to lodge upon while being fed by the chute into the furnace.

B is the chute, consisting, in the main, of an inclined board or plate, with its lower forward end bent down perpendicularly and formiu g a (No model.)

scraper or pusher head, I), which moves along the bottom a to carry the fuel resting thereon forward and feed it into the furnace. At the sides of the same end of the chute are clips or arms I), which embrace the ways A to confine and permit of the sliding of the chute upon the ways. This chute is secured upon a frame or carriage, B, having flanged wheels N, which run upon the ways A as the chute is carried back and forth.

lonnected to the under side of the chute is a pitman, 0, also connected to a crank-shaft or eccentric, d, driven-by a pulley and band or otherwise, by which a forward motion is imparted to the chute to enable the feeding of the fuel-saw-dustitmay, be-into the furnace, and then a backward motion to the chute to withdraw it from the furnace front or door to receive another supply of fuel.

'Hung under the carriage or chute, within eyes suitably formed in connection with the lower cross-part of the carriage, are two long bars, 0, with their forward ends resting in suitable supports or openings e in the furnacefront, arranged in a plane slightly above the furnace-grate. The rear ends of these bars or arms are curved or bent outwardly in the same horizontal plane, as at G O, to cause them to upon a suitable support, 9, at the same end of the feeder for that purpose, and throw the forward ends of the said arms or bars apart during the forward movement of the chute, and thus agitate the burning fuel,shake down ashes, and give the fire a quickened impulse to consume the fresh supply of fuel being simultaneously fed from the chute.

As the chute is moved backward, carrying with it the arms or bars 0, it will be noticed that the backs of the curved portions 0 G of said bars will be brought in contact with additional frictional rolls h h, arranged rearwardly a short distance from the rolls .f, and thus cause the forward ends of said arms or bars to approach each other until in a parallel position as they are withdrawn from the fire.

From the foregoing it will be further noticed that the interposition of the hand 'or other means, to either convey the fuel to the furnacedoor or push it off the bottom of the chute,

where such is provided, into the furnace, is entirely obviated, as, while the fuel is leaving the incline of the hopper or chute, it is also being carried toward and fed into the furnace, and that, lodging upon the bottom affixed to the ways upon which the chute runs, is being pushed off and completely removed therefrom into the furnace.

The ways, with their affixed bottom, and the immediately-closing furnace-door, prevent the accidental falling out of the furnace upon the floor ofignited or burning fuel.

Having thus fully described my invention, Iclaim and. desire to secure by Letters Patcut- 1. In afuel-feeder, the combination, with the carriage, having the chute or hopper,'of the fire stirrers or bars adapted, in addition to having a back-and-forth motion and capable of being spread apart with the forward motion of the carriage or chute, to approach each other and occupy a parallel position as the chute or carriage moves away from the furmace-door, substantially as and for the purpose set forth.

2. In a fuel-feeder for furnaces, the combinaation substantially as hereinbefore set forth, of the horizontal chute or bottom a, the inclined chute B, placed on and running to and fro on the bottom a, and having its forward end formed into a pusher-head, b, and the necessary clips to hold the chute B on the guideways of the chute a, substantially as set forth.

In testimony whereof I affix my signature, in presence of two witnesses, on this 5th day of March, 1881.

ISRAEL ERIOKSON.
