PATENT PHILIP W. PRATT, OF ABINGTON, MASSACHUSETTS.
IMPROVEMENT IN DEVICES FOR OPERATING GRATE-BARS.
Specification formingpart of Letters Patent No. 182,223, dated September 12, 1876; application filed l 1 December, 13, 1875.
To all whom it may concern:
Be it known that I, PHILIP W. PRATT, of Abington, in the county of Plymouth and State of Massachusetts, have invented certain,
new and useful Improvements in Grate-Bars,
, of which the following is a specification:
tion being communicated by the action of a lever or some other suitable device worked by the fireman. a
Figure l is a plan showing two long bars of one set, and a few short bars or projecting pieces of the other set. Fig. 2 is a vertical sectionof the same lengthwise of the grate. Fig. 3 is a cross vertical section of the same. Fig. 4 shows in elevation one of the short bars or projectors. Fig. 5 is a plan of a part of a long plate that serves tohold the lower ends of the short bars-orprojectors.
Let A represent the walls of a furnace. B, Figs. 1, 2, and 3, is a flat cross-bar pivoted at b b, as shown in Figs. 1 and 2, so that it may have a rocking motion, the rocking motion being imparted to it by the lever D, Figs. 1 and 2. As the pivots'b are nearer to edge at than the edge 01, it is evident that when the cross-bar B is rocked the motion of the edge (1 will be less than the motion of the edge d. The same may be said of the rear crossbar B. Thegrate-bar H is provided with small projections h h, as shown. These bars H H are connected loosely to the rocking cross-bars B B by the arms E, Fig. 2, so that when the cross-bars B and B are rocked the grate-bars H H move up and down vertically. L, Figs. 2, 3, and.5, is one of a series of longitudinal plates placed under the grate-bars, as shown. These plates are attached to the rocking bars B and B by the arms F, Fig. 2. The arms F connect the plate L to the edge d of the rockersB and B, so that the motion of L is greater than the motion of the grate-bars H, when the rockers B and B are moved. Between each turned in one direction this oblong enlargement can pass through the hole M in the plate L, Fig. 5, the parts being so arranged that when the lower end of the projectoris passed through the plate L, and the said projector turned a quarter, it will be locked into the plate L, as shown in Figs. 2 and 3. As the projectors K are attached to the plate L, it is evident that they will move whenever the rockers B and B are moved, the arrangement being such that when'the projectors K K are going down the grate-bars H will be going up, and vice versa. The form and style of these bars may be varied to suit the requirements of difl'erent kinds of fuel. If desirable, a set of long bars may take the place of the projectors K, or the long Y bars H may be omitted, and a series of projectors substituted for them. The two rocking plates B and B are connected together by the rods P, as shown in Fig. 2.
I claim as my inventiona 1. The combination of the rocking plates B B and the rod P with the arms E E and bars H, all operating together substantiallyas described, and for the purpose set forth.
2. The combination of the rocking plates B B and the rod P with the plate L, arms F, and projectionsK K, all operating together substantially as described, and for the purpose set forth.
PHILIP W. PRATT.
