SHAKING-GRATE To all whom it may concer/n:

Be it known that we, Jamas REAGAN and WILLIAM REAGAN, citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Shaking-Grate, of which the followinvi is a specification.

Our invention relates to a new and useful shaking grate and consists in providing lifting fire bars which can be used with or without choppers and each of which lifting fire bars is capable of being removed and replaced without disturbing the remainder.

It further consists of a novel construction of lifting fire bars whereby the coal is prevented from leaving the grate when the parts are operated.

It further consists of novel means of mounting the lifting fire bars.

It further consists of novel details of construction all as will be hereinafter fully set forth.

Figure 1 represents a sectional view of a portion of a grate showing a lifting fire bar in position with a portion of the device for operating the same. Fig. 2 represents a sectional view showing the lifting bar in position alternately with choppers and stationary fire bars. Fig. 3 represents a top plan view of one of the lifting fire bars. Fig. 4 represents a sectional view on line sux, Fig. 3. Fig. 5 represents a perspective view of locking sleeve employed. F ig. 6 represents a longitudinal section of another embodiment of our invention. Fig. 7 represents a transverse section of Fig. 6'. Fig. 8 represents a rear elevation of one of the lifting fire bars.

Similar numerals of reference indicate corres onding parts in the figures.

Iiieferring to the drawings: IVe have found in shaking grates that it is necessary to provide a construction wherein there are no dead points in the 'lire and in which free passage of air is permitted and caused in order that a suitable draft is provided. Our invention is designed to accomplish these results and in the drawings we have shown a construction for carrying out our invention but it will be evident that various changes maybe made which -Will come within the scope of our invention and we do not, therefore, desire to be limited in every instance to the exact construction as herein' shown and described but desire to make such changes as may be necessary. We desire it understood that the lift- Specification of Letters Patent.

ing fire bars can be arranged for use on any suitable grate construction and we desire to use the same either in conjunction with rocking choppers or not, as may be necessary. In some instancesJ we may alternate the lifting Vfire bars with choppers or we may make one section entirely of the lifting fire ba rs, the use and arrangement of the parts depei'idingl upon the conditions.

l designates a frame or portion thereof of a shaking grate of suitable construction and 2 designates choppers which are suitably mounted in order to be rocked, each of said choppers in the present instance being mounted u on the chopper bars 8, which are I angular anc one or more of the choppers being provided with the depending portion 4t to which the rocking mechanism can be attached in any suitable manner.

It will be understood that we may ulount our lifting fire bars directly between the choppers or as we have shown in the drawings, we may provide the stationary 'lire bars 5 which are suitably supported in any desired manner and which are adapted to rest preferably upon a suitable portion of the frame l and can be lifted Vfrom position or returned thereto by hand. Between the lire bars 5, are placed the hollow lifting 'lire bars 6 the same having the sides or wings 7 with the openings or slots 8 therethrough and the front side 9 being provided with slots or recesses 10, it being understood and noted that the slots are provided for the purpose of Apermitting a free passage of air therethrough. rlhe Vfront side 9, it will be noted, is preferably curved downwardly and rearwardly as best understood from Fig. I and is provided with the sides 1l, said .front side 9 and sides Il extending a considerable distance below the sides 7, and to a suitable portion. of said front side 9 is pivoted or otherwise secured a bar I2 which is connected with a suitable actuating mechanism for the lifting fire bars.

I3 designates a circular opening formed in the sides 7 with which communicates a slot I4 formed in the sides 7 and which slot let is slightly narrower than the diameter of the circular opening 13, but which is capable of passing the chopper bai-3.

15 designates a sleeve or collar which is provided with an angular opening 16 to receive the bar 3 and which is adapted for slid ing movement thereon, the circumference of said sleeve 15 being adapted to suitably fit the opening 13 in the lifting lire bars 6. Projecting from opposite ends of the sleeve 15 are the lugs or lips 17 which are of a suitable size in order to freely pass the slot 14 leading to the circular opening 13 when in proper position therefor, it being noted that the normal position of said sleeve 15 is within the openings 13 with the lips 17 engaging the sides of the lifting fire bars 6, this construction being best seen in Fig. 1 and in full lin es Fig. 2 and it being understood that said sleeve 15 serves as the fulcrum or support for the lifting fire bar 6. The upper face of the fire bar 6 is provided with the slots or openings 18 and with a transversely extending shoulder 19 adjacent the rear end of the bar. ln the figure we have shown the lifting bars in conjunction with the choppers and the stationary fire bars but as previously stated, we may in some instances use a plurality of fire bars without the choppers and stationary re bars or we may use the lifting fire bars and the rocking choppers Without the stationary fire bars.

The operation of the parts just described will be apparent. The parts being in the position seen in Fig. 1 the choppers 2 can be actuated by suitable movement of the depending portions 4 and the lifting fire bars can be actuated by suitable movement of the bars 12, it being understood that when the bar 12 is moved in a direction indicated by the arrow in Fig. 1 that the front side 9 will be elevated, carrying with it that end of the lifting fire bar which will be rotated on the sleeve 15 as previously described and the shoulder 19 extending transversely of the upper face will prevent the escape of the coal, it being understood that the lifting lire bars can be suitably actuated in order that the same can be raised to any desired angle. The wings and sides 7 of the lire bars when raised, prevent the green coal from leaving the furnace since they form a bar for that purpose and close up any opening which might otherwise occur if these wings were not of suitable size and dimension therefor. The slots or openings in the lifting fire bar not only permit free passage of air, but increase the air supply, thus insuring a draft and assist in preventing any dead points in the fire.

By reason of the arrangements above described any one of the lifting fire bars can be removed without disturbing the remainder, this being accomplished by removing one of the fire bars 5 and by rotating the bar 3 the sleeve 15 will also be rotated therewith until the lugs 17 are in line with the slots 14 in the sides 7 of the lifting bars 6 after which the vSaid sleeve can be moved along the rod 3 into position seen in dotted lines, Fig. 2, and by releasing the connection of the front side 9 with the bar 12 the lifting fire bar 6 can be removed vertically from the position in the grate since the slot 14 permits free passage of instances, we may employ a square rod which passes through a suitable squared opening 2O in the sides 11 of each of the lifting fire bars which will connect a series of these lifting fire bars so that the operation of one will actuate all. By reason of the actuating means with the front end of the liftingl fire bar 6, that is with the long axes thereof, the direct power is applied to the longest radius, the effect of which is evident.

ln the embodiment seen in Figs. 6 to 8 inelusive, we have shown another embodiment of our invention which it is preferable to employ in conjunction with certain kinds of fuel, and this embodiment, in construction and o eration, corresponds to that already descri ed with reference to Figs. 1 to 5 inclusive, except that the front side 21 of the lifting grate is not connected with the bar 12 but the rear side 22 is connected with the bar 12 as indicated at 23 and a squared opening 24 is provided in the rear portion of the lifting grate instead of in the front portion thereof.

W'e desire to call attention to the fact that our invention takes the place, or at least obviates the use of the Stoker-bar in slicing the fires, for the reasons, that it uniformly Stokes the fire from the bridge-Wall to the dead plate, its movement is such as to keep the fire in a porous condition at all times and thereby dissolve clinkers in their infancy, permitting a continuous supply` and flow of air through the fuel with the result of perfect combustion. From actual experience we have noted, when the stoking device was in action, i. e., when it was lifted into the hre, the fire being broken and the clinkers dissolved that the air is permitted to pass through, and the entire bed of fuel was immediately ignited with what seemed to be an explosion.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is :i
