JOSEPH ALBERT HILL, 0F SHEFFIELD, ENGLAND.

FURNACE-GRATE FOR LOCOMOTI'VE AND LIKE BOILERS AND OTHER PURPOSES.

Application filed March 12, 1912.

To all whom it may concern 1 Be it known that I, JOSEPH ALBERT HILL, :1 subject of the King of Great Britain and Ireland, and resident of Bernard Road, Park, Sheffield, in the county of York, England, have invented a certain new and useful Improved Furnace-Grate for Locomotive and like Boilers and other Purposes, of which the following is a specification.

This invention relates to furnace grates for locomotive and other boilers of the type composed of two or more portions adapted to be tilted about their longitudinal axes in such a manner as to leave one or more gaps or slots through which the fire can be dropped thus obviating the usual tedious operation of dropping the fire-bars severally which leads to considerable delay in drawing the fire.

The object of the present invention is to devise an improved form of furnace grate of the above type in which the manipulation of the grate sections and of the bars composing the same shall be greatly simplified and facilitated, and the invention consists in a furnace grate for locomotive and other boilers divided into two or more portions and provided with separate and independent gears enabling the fire-bars to be shaken or the parts of the furnace grate to be rocked as a whole.

The invention also consists in adapting a single operating device to actuate both the shaking and rocking gears.

The invention further comprises the special form of furnace grate hereinafter more particularly described.

The accompanying drawings illustrate one mode of carrying out the invention.

Figure 1 is a longitudinal sectional elevation showing one convenient form of furnace grate constructed in accordance with the invention. Fig. 2- is a front elevation of a part of Fig. 1. Fig. 3 is a plan of a detail of Fig. 2. Fig. 4 is a view illustrating the rocking of the furnace grate. Fig. 5 is a similar view illustrating the shaking of the fire-bars, while Fig. 6 is a plan on a somewhat larger scale showing a portion of the rocking and shaking gears.

In carrying my invention into effect in one convenient manner when applying it, for example, to a furnace grate for locomotives of the type which is provided with a plurality of longitudinally arranged air Specification of Letters Patent.

Serial No. 683,199.

conduits for facilitating the passage of air to the fuel and also for collecting the ashes for subsequent removal from the conduits by steam or like jets, the conduits a supporting transverse fire-bars c and of which there may be any convenient number (four such conduits being illustrated in the drawings) are rotatably mounted within the firebox, for example, by means of plate or like members a which are secured to or formed integral with pins 6 mounted in suitable bearings 0, carried by the walls (Z of the fire-box.

The conduits are carried rotatably in the plates u in any suitable manner and for the purpose of providing for both the rocking of the grate sections carried by the plates 'uand the shaking of the individual conduits and the bars carried thereby I provide twosets of rods-e connected in any suitable manner with corresponding sets of bell crank levers g h pivotally mounted upon some fixed portion of the framing of the locomotive or of the fire-box and coupled together respectively by rods 2' 70 upon which lugs or brackets Z m are rigidly mounted.

The lugs Z m are provided with slots adapted to be engaged when required by lugs or projections 12 carried by a lever 0 working in a guide plate p fixed in any con- .venient position in the cab of the locomotive.

ment is such that when the lever 0 is workng in the slot its lower end is 1n engagement with the lug or bracket Z and consequently movement of the lever through the medium of the link 2' operates the bell crank levers g and rods e so that the individual conduits, and with them the fire-bars, are tilted in the manner shown in 5, the oscillatory movement of the conduits being effected through the intermediary of the T shaped or other suitable bars or connecting members t attached both to the conduits and to the rods e.

When the lever 0 is moved across the slot 8 its lower end is disengaged from the bracket Z and engages with the bracket m so that movement of the lever in the slot 1' operates the bell crank levers h and through them the rods 7 so that the brackets u are thereby tilted in the manner shown 'points at which the rods 6, are connected with the bracket members 6 secured to the conduits are situated in or approximately in the axes of rotation of the pins 6 of the bracket members a and any slight movement that might be given to the rods due to slight inaccuracy in the fitting of the apparatus can be eliminated by providing a slot at one end at each of the bars 6.

Ifdesired the grate may be formed in two halves, either of which may be adapted to be tilted when required, or both may be separately tilted, separate operating mechanisms for the two halves of the grate being provided, if necessary, for this purpose. Such an arrangement allows of only onehalf of the fire being worked at a time, if desirable, the remaining part of the grate being thrown out of action by being tilted out of the horizontal.

A further advantage of the arrangement is that the firemen may work the clean fire on to one-half of the grate and the clinker and ash on to the other half which may then be tilted for the purpose of getting rid of the waste after which this latter portion of the grate may be returned to its normal position and the cleaned fire worked all over the grate area.

It will thus be seen that by means of my mproved arrangement the furnace grate can be thoroughly shaken during the running of the locomotive and the operations of devices for actuating the rocking and shaking gear may be provided if desired.

Having now described my invention what I claim as new and desire to secure by Letters Patent is 1. A furnace grate for locomotive and other boilers and for other purposes comprising a plurality of sections comprising pivotally mounted fire-bars, link mechanism for eifecting the tilting of said sections about their longitudinal axes, a second set of link mechanism for effecting the shaking of the fire-bars composing each section, a lever for operating either set of link mechanism as desired, and a guide plate having an angled slot for controlling the movements of the lever.

2. A furnace grate for locomotive and other boilers and for other purposes comprising two sections, each of which is composed of two conduits supporting transverse fire-bars therein, link mechanism for rocking the grate sections about their longitudinal axes, a second set of link mechanism for oscillating the individual conduits forming the sections, and a single operating member for actuating either set of link mechanism as desired.

3. A furnace grate for locomotive and other boilers and for other purposes comprising two sections, each of which is composed of two conduits supporting transverse fire-bars therein, link mechanism for rocking the grate sections about their longitudinal axes, a second set of link mechanism for oscillating the individual conduits forming the sections, a single lever for actuating either set of link mechanism as desired, and an angled guide controlling the movements of said lever.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH ALBERT HILL.
