FIRE GRATE Fi'led Dec. 9, 1946 INVENTOR; 0/: r/ 5 77a 22 A TTOR/VEX Patented Sept. 20, 1949 2,482,191 Gem sti s. ass" it: et: Application December 9, 1946, Serial No. 714,942.. 3 Claims. (01. is e-"i653 A This invention relates generally to fire grates and has particular reference to grates of this kind as used in vehicles or carriers, especially locomotives.

Carriers or vehicles of this kind are used in travel or movement which may tend to displace parts thereof and a particular object of this invention is the provision of means for keeping in proper place, and from jumping or undesirable relative movement of the grate structures of railroad locomotives.

Another object is the provision of an improved feature in fire grates which is capable of installment with the grates proper, which necessitates only minor changes in the grates for such installment, and which, though highly efiicient, is still of a simplified nature.

A further object is to provide an improved attachment of this kind which is of a permanent nature, and which is so located as to be protected against being burned out.

A feature of the invention connected with the foregoing resides in a shaft, extension or arm of the grate; and shaft retaining means in the form of a rod or pin, with linkage including hook and shank means connecting said rod and the shaft.

A protection for said shaft, as aforesaid, is provided in part and in accordance with still another object of the invention, by dead ashes from the fuel consumed on the grate.

With the above indicated objects and advantages in view, as well as others which will hereinafter appear, the invention resides in certain novel constructions, elements and combinations of parts, the essential features of which are herein fully described and illustrated in the accompanying drawing, in which:

Fig. 1 is a plan view of an organization including a fuel grate constructed in accordance with this invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a fragmentary plan view showing a modification of structure, and

Fig. 5 is a further modification of the structure shown in preceding figures.

In said drawing is shown a usual support or bridge structure I0, opposite sides of which are alike, the ends of bridge I0 being supported by the furnace structure, not shown. On one side of the support is a grate II, and on the opposite side of said support is another grate H. Each grate I I, with its associated parts and extensions is the same as the other, so that a description of one is also applicable to the other, as identified by like reference characters.

A body portion l l of a grate of this kind, having various types of openings therein, is well known to those skilled in the art, therefore this portion II is herein shown diagrammatically. The body I0 provides a seat for shaft l4 above a lower extension I2 which is formed with recess I3.

From the grate II, of suitable material, extends a shaft I4, above the expansion [2, the other end of the grate ll being supported by the furnace structure, not shown, so that this grate is maintained at proper level for use. With the recess l3, a recess H3, at right angles to the first recess communicates, and transverse to the recess I5 is a bore I6, extending through the support ID, the bore [6 therefore having opposite ends opening outwardly at the sides of said support.

Disposed in the bore I6 is a rod I1 and in each end of the rod I I is a perforation to receive a cotter pin 20, the latter being outside of a disc or washer 2| thereat.

The red I! is therefore easily removable as for taking apart any member of the structures, and for assembly. This rod I1 and the shaft I4 are connected by a link 22, having a rin end 23 on said shaft and a hooked end 24 on the rod IT. The material of the shaft I4, rod, and linkage 22 is the same as that of the grate II.

In Fig. 4 is shown a shaft I4 having therein an annular groove 26 in which a ring end I23 of the link 22 is disposed, the end or ring I23 being therefore flush with or below the surface of said shaft.

In Fig. 5 the shaft I4 is shortened and has a tapped hole to retain a screw I24, the same being equivalent to the reduced portion of shaft I4 in Fig. 4.

Variations may be resorted to within the scope of the invention and parts of the improvements may be used without others.

Having described my invention I claim as new:

1. In combination with a grate, a support with a seat therein, a shaft extending from the grate to said seat, said support having therein a recess at right angles to the shaft, said support having also therein and in communication with the recess, a bore, a rod within said bore, and non-inflammable means connecting said shaft and said rod, said means disposed in said recess.

2. In combination with a grate bar, a support with a seat, a shaft extending from the bar to said seat, said support having therein a recess at right angles to the shaft, the support having also therein transverse to the recess and communicating with said recess a bore, a rod disposed. in said bore, fire-proof linkage terminally engaging said shaft and said rod, the linkage having a shank in the recess, and holding means engaging said rod at opposite ends of said bore.

3. In combination with a pair of grate members and an interposed support having therein a pair of recesses providing seats, said support having a second pair of recesses at right angles to the first recesses and communicating with the first recesses, said support having extending therethrough and communicating with the second mentioned recesses through a bore, a rod passing through said bore, linkage disposed in said second recesses and having terminals engaging the respective shafts and terminals en gaging said rod, said rod having perforations in I 4 the outer ends thereof, and means cooperating with said perforations and holdingly engaging said ends of the rod.
