ALFRED WILLIAM BENNIS, 0F LITTLE HULTON, BOLTON, ENGLAND.
FURNACE-GRATE.
Specification of Letters Patent.
Patented May 21, 1918.
Application filed March 29, 1915. Serial No. 17,858.
To all whom it may concern.
Be it known that I, ALFRED WILLIAM BENNIS, a subject of the King of Great Britain, residing at Little Hulton, Bolton, in the county of Lancaster, in the Kingdom of England, have invented certain new and useful Improvements in and Relating to Furnace-Grates.
The present invention relates to improvements in furnace grates with the object to increase the effective life of the grate.
According to the present invention, bars or links in a chain grate, are flexibly interconnected intermediate of their length to one another, so that breakage of a link at or near the link rods, will not cause the falling down of the link or bar, and consequently necessitate immediate repairs.
In one form of construction, the links are formed with projections and depressions along their sides, the depressions of one link or bar engaging with the projections on the neighboring link or bar, so that if a link or bar breaks at its end, it will still be supported by its neighbors.
This invention is more particularly described with reference to one form of construction illustrated in the accompanying in which Figure 1 is a side elevation; and
Fig. 2 is a corresponding plan view.
The links 1 are provided with mutually interengaging parts in the form shown consisting of projections or lugs 2 on the one member adapted to engage with recesses 3 on the neighboring link.
The links have holes at either end so that they may be threaded on link rods 4: in the usual manner.
Any suitable number of studs and corresponding depressions can be arranged on the sides of the links of the chain grate as desired, the number being adapted to the length between the centers of the pivotal portions of the links.
The projections and corresponding depressions may be disposed in the manner shown on the drawings, or alternatively all five cents each,
the projections may be at one side and the depressions on the other. The arrangement of the present invention can be directly adapted to the general forms or disposition of links in useon chain grates.
Other minor variations will readily suggest themselves, and are contemplated. The arrangement shown on the drawings of members carried by one link engaging with recessed portions on the other link is however, the preferred construction.
It will be seen that the present invention has the advantage that the chain grate may run under load for a considerable time even though it may have among its component parts several broken links, as the links are prevented from falling away from the main chain and causing a jam through meeting with some projections or roller.
I declare that what I claim is 1. A chain grate comprising in combina tion, links; interengaging pivots at each end of said links forming driving means enabling their forward movement; and lugs and mating recesses so formed on the sides of the links that each link enters into supporting engagement with each laterally adjacent link at two points intermediate their end pivots.
2. A chain grate comprising in combination a plurality of counterpart links having interengaging ends adapted for pivotal con nection, the links having lugs and recesses on their sides whereby each link is adapted to enter into supporting engagement with each laterally adjacent link at two points intermediate its ends; and pivotal supporting and connecting means for the ends of the links.
In witness whereof, I have hereunto signed my name this 16th day of March, 1915, in the presence of two subscribing wit nesses.
ALFRED WILLIAM BENNIS.
