VILLIAM E. KELLY, OF NEXV BRUNSVICK, NElV JERSEY.
G RATE-BAR.
SPECIFICATION forming part of Letters Patent No. 394,984, dated December 25, 1888.
Application filed August 23, 1888.
To a whom it may concern.-
Be it known that I, WILLIAM E. KELLY, of New Brunswick, in the county of Middlesex and State of New Jersey, have invented a certain new and useful Improvement in Grate-Bars, of which the following is a specilication.
My improvement relates to gratedmrs provided with detachable leaves.
The improvement consists, essentially, in the combination, with a grate-bar having its upper portion made of uniform width, but sinuous in a vertical direction, of a number of leaves having slots or openings, also made sinuous in a vertical direction, so as -to be adapted to interlock with the sinuous portion of the bar. The bar will preferably be provided with a straight portion, over which the leaves may be moved downwardly and from which they may be slid laterally over the sinuous portion of the bar.
In the accompanying drawings, Figure 1 is a side view of a grate-bar embodying my improvement, some of the leaves being shown in transverse section. Fig. 2 is a transverse vertical section taken at the plane of the dotted line :r, Fig. 1. Fig. 3 is a transverse vertical section taken at the plane of the dotted line y y, Fig. 1.
Similar letters of reference designate corresponding parts in all the figures.
A designates a grate-bar. It may be of any desired construction, strengthened with ribs a a or in any other approved style. It may have trunn-ions at the ends. I have shown one such trunnion, a Adjacent to the trunnion I have shown an end flange or rib, a
B designates a number of leaves. These maybe of any desired configuration and construction, excepting as to the portion engaging with the bar A. The upper portion, a, of the bar A is of uniform width, but is sinuous in a vertical direction, as may be best understood by reference to Fig. 3. As shown, the upper portion, o curves first to one side and then to the other, or, in other words, is made with an upwardly-extending ogee curve. Any other sinuous shape may, however, suffice, and it is not necessary that the sinuosity should be curved. The sinuous portion will,

however, be of substantially uni form width or thickness throughout its extent. Each of the leaves B has an opening, 11, extending from the lower extremity upward. This opening will be made sinuous to correspond with the sinuousity of the upper portion, a of the bar A. A is so formed at one point in its length (in the present instance at the plane of the dotted line 0; ac, Fig. 1,) as to permit of one of the leaves B,provided with the sinuous opening, being slipped vertically downward. It will be understood that this is accomplished by forming a vertically-extending recess, 1), in the upper portion of the sinuous portion a of the bar on one side, and a similar recess, 12 in the lower portion of the other side of the sinuous portion of the bar. This may best be understood by reference to Fig. 2.
Each leaf B is slipped downwardly through the recesses 12 b of the bar. downwardly as far as possible, each leaf is moved laterally, or, in other words, in the direction of the length of the bar. Vhen thus moved laterally beyond the recesses 17 5 its opening will engage with and slide along the sinuousities of the upper portion, of, of the bar and interlock therewith. The leaves B so applied to the bar cannot be removed except by being severally moved lengthwise of the bar to a position opposite the recesses b 19 whereupon they may severally be lifted upwardly oif the bar.
I have shown the bar asprovided with a master-leaf, B. This master-leaf has an opening which, as represented, differs from the openin g in each leaf B in that it is straight-sided instead of having sinuous sides. This leaf is shown as made longer in a vertical direction, so as to extend below that part of the bar A which it straddles. A linchpin, O, is extended through the lower end of the leaf B below the bar A. It prevents the leaf B from being lifted off or removed in a vertical direction. The removal of the linchpin will, however, permit the detachment of the leaf B. Any equivalent device may be employed instead of the linchpin.
The sinuous or corrugated nature of the upper portion, d of the bar A not only serves The upper sinuous portion, a, of the bar.
hen moved as a convenient and desirable means for se curing the leaves 13, but is also desirable because of the advantages it affords in respect to expansion and ("Oll'filflCtlOll oeeurrin in the structure.
\Vhnt I claim as my invent-ion and desire to secure by Letters Patent, is-
