Specification of Letters Patent.

Patented Dec. 26, 1911.

Application led November 10, 1910. Serial No. 591,687.

To all whom it mm] concern:

Be it known that I, JOSEPH ANRIG, a citi zen of the United States, residing at West Hoboken, in the county of Hudson and State have invented certain new and useful Improvements in Tilting Furnace-Grates, of which the following is a This invention relatesto tilting furnace grates, that may be adj usted to any desired inclined position, depending upon the size of the coal used, and the invention consists of parts having particular construction and form, and :specially with another, whereby it is .believed greater convenience and economy 1n the handling and consumption of fuel results, and the whole is rendered easy to manufacture or to repair. Y

The construction and arrangement comprising this invention is illustrated in the accompanying drawings, of which- Y Figure 1 represents a vertical, longitudinal section of a boiler setting and furnace to which this invention has been applied. Fig. 2 is a horizontal section through the holding tube or sleevefor the guide rod, and, Eig. 3 is a cross-section of the track for the rollers.

Each part illustrated and described is designated throughout the `drawings and specication by the same letter of reference.,

lraising the grate,

Considering the drawings, A represents a boiler B a furnace, int which coal enters from a hopper C, descending upon the grate D. The grate has a front pivot E, and is arranged to be swung upwardly from the position shown, along the curved back wall F.

The position of the grate illustrated in Fig. 1 is its lowest position, and it may be caused to assume any inclined position up to the horizontal indicated by the broken. line J3-d. A satisfactory and durable means for and for holding it secjarely in the position to which it may be adjusted, comprises the lug G on the grate at the rear,

to which is pivotally'joined a connecting rod the rod andscrew being alined. To keep the rod and screw in alinement, the breast M of the furnace has at its lower part the tube m, one end of whichfis threaded to engage v the screw, while the rod enters the other or and its object is to provide a grate arranged and associated one inner end of the tube.- shown that by operating) the handwheel of the screw, pressure may e exerted upon the rod` K, 'and through connecting rod- H upon It is believed to be the rearV of the grate, which willconsel quently be swung upward upon its pivot E. In practice, the breast M of the furnace is made removable, and carries with'it the hopper, and the grate, andv all the parts attached thereto. A

In lig` 1 it is shown that the hopper C is attached to and supported by the 'front orbreast M of the furnace, and the hopper is brought into place when thebreast M is moved up to the furnace walls into the position illustrated.

It will be understood, that when the screw L is turned to raise the grate, the rollers J take the weight in part, and, it is advantageous to provide the track y'. for the rollers. The track is best illustrated in Figs. Q-ad 3. 4It will be also noted that the rollers sustain part of the weight of the grate and its load of fuel or ashes, when the breast M is moved outwardly; The breast is moved outwardly, when it is desired to dump the grate. Ordinarily, the lire may be adequately manipulated-by means of a suitable implement or poker N introduced through the orifice n in the furnace'breast. When the grate has. been adjusted to the desired inclination, and the breast M is in -normal position, the rear of the grate is back wall F to prevent the from falling too fast. dump the grate, the breast is moved outwardly as set forth.

Having now described this invention, and explained its mode of operation, what claim is 1. In a furnace, 'the cmbination with a furnace having a curved back wall, of a fur` nace breast having an opening for the introduction of fuel, a grate pivotally connected with said breast immediately below said opening, the rear of the grate being movable up .and down near said curved back wall and upon a like curve whereby fuel is prevented from falling from the rear of the grate, a horizontal screw arranged at thebottom of fuel at the rear If it is desired to near enough to the curved? sf ioo the breast, a guide rod arranged to be moved by the screw, means constructed to engage the screw and guide said rod, a connecting traek constructed and arranged to afford a path for the rollers whereby the weight of .the grate is supported.

vimmediately below said opening, the rear of the grate being movable up and down near said curved back wall and upon a like curve lwhereby fuel is prevented from falling from the rear of the grate, a horizontal screw ar'- 'ranged at the bottom of the breast, a guide rod arranged to be moved by thescrew,`

means construeted to engage the screw and guide said rod, a connecting rod arranged to pivotally connect said rod and the rear of said grate, rollers arranged at the lower end of the connecting rod, and a track constructed and arranged to afford a path for the rollers whereby the Weight of the grate is supported.

lIn testimony whereof l afliX my signature n presence of two witnesses.
