such Vas will enable others slrilledin the art I to which it appertains to make and use the same.

This invention relates to an improved coal grate and one object of the invention is to provide a grate which may bey formed in a plurality of sections connected in Van im-V proved manner and producing a grate which will be. securely held in the set upposition whenin use. a Y. y

Another object of theinvention is to provide an improved construction of bottom Ygrating and improved means for mounting this grating for horizontal swinging movement when shaking a fire, the grating being pivotally mounted and supported in an improved manner and further so mounted that while it may be easily removed and put in place when desired, it cannot readily become accidentally knocked out of'place.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a view showingthe improved grate in front elevation and placed within a fireplace. Y

Fig. 2 is a vertical sectional view taken along the line .2 2 of Fig.j1.`

Fig. 3 is an enlarged vertical sectional view taken along the line 3 3 of Fig. 1.

Fig. 4t is a vertical sectional view taken along the line 4- 1 of Fig. 3.

Fig. 5 is a transverse sectional view taken along the line 5 5 of Fig. 3.

Fig. 6 is a perspective view of the bottom grating Vof the grate.

This improved grate is provided'with a `lire box having end walls 1 and 2, a front wall 3 and al rear wall 4. The end walls 1 and 2 are extended below the front and rear walls to provide supporting feet 5 and the end walls are provided with inwardly extending ledges 6 which taper rearwardly and provide supports for the bottom grating 7. This grating 7 rests upon the supporting ledges and is provided at its rear or inner end with a notch 8 to receive the pin extension 9 of the rear wall 4. This pin extenup position.

sion provid-es a fulcrum Vto pivotally mount the bottoni grating thus permitting the bottom grating to befoscillated horizontally by means of the handlel extension .10 at its forward end. This handle extension 10 will be grasped by means of a suitable shaker (not shown) and ashes canthus'be readily caused to pass through the slots of the grating. A lug 11 is provided .to the i'ear of the handle extension 10 and the front wall is providedV intermediate its length with a notch 12so thatthe grating can be put in place beneath the front wall. When this grating is put in place, the lug passes through the notch 12 and by moving the grating to one side, the lug can be moved Y out of direct alinement with the notch thus preventing any danger of the grating` being accidentally moved forwardly out of the proper position. v The end'walls 1 and 2 are provided at their forward ends with hooked arm extensions 13 for engaging the upper side portions of the front wall and the front wall is provided withvarm extensions 14: for engaging the lower forward portions of the end walls 1 and 2. Arm extensions 15 are provided at the upper vrear end portions of the end walls to engage the rear wall, and arms 16 are carried bythe rear wall for engaging the end walls 1 and 2. Fastener bolts 17 pass through the arm extensions and through the walls so that these walls may be securely but releasably heldin a set- It should be noted that these walls are firmly held against any movement when the bolts are in place and therefore the grate cannot become distorted.

The end wall is provided with rearwardly extending side flanges 2O for engaging the rear or inner wall of a fire place and further has its upper portion 4 inclined outwardly to overhang the tire box as shown clearly in Fig. 3. From an inspection of this figure, it will be seen that the rear wall together with its side flanges 2O and headplate 21 will provide a box-like structure when the grate is in place thus providing an air chamber in which air may accumulate and pass out through the openings 22 formed in the rear wall. The openings 22 formed in the lower portion of this rear wall are provided in rows between the ribs 28 which taper upwardly and will serve to hold the coal in spaced relation to the rear wall. Therefore, air can pass into the fire-box front wall and the tongues 14 engaging the through the openings 22Yformed in thelower portion of the wall 4 and of course, may also pass into the re-boxthroughthe usual openings 24 formed inthe walls of the-re-box.

- In addition, a'portion of the air in the air chamber at the rear of the grate will pass out through the openings in the upper portionof the wall 4 and this air which discharges from the air chamber above theVfire-boX will serve to drive the heat from the fire out into the room, the inclined upper portion 4 of the wall 4 serving` as a deflecting surface.

`When this grate is 'to beused, it will be V assembled as shown with the tongues 13 of the end walls engaging' the outer face of the outer faces of the end walls .The securing bolts for these tongues will be put in place and the `end walls .will then jbe. connected with the side flanges 2O vof the rear -wall by passing bolts through the slotsYV of the tongues l5 and 16 carried by the end walls and rear wall. The bottom grating will be put in place and the grate is then ready to be installed. When the grate is placed in the fire-place 25, 'the flanges or walls 2OV and the head-plate 2l will engage the inner'wall 26 of the'fire-place and thus vprovidethe` air chamber tol receive the air which is to be fed into the fire-box through the rear wall 'and v which is to pass through the openings in vthe overhanging upperpoition of this rear wall. l The lire will be started and asthis fire vburns, the overhanging upper'section of the rear wall will provide a deflector 'surface and the air passing through the openings in this overhanging upper portion of the wall will serve to drive the heat out into the room. The ribs 23 serve to prevent the coal Vfrom accumulating in the rear portion of the 'fire-box against the rear wall and therefore there will be no danger of the openings iii Y this rear wall becoming stopped up by ashes. vWhen it is desiredl to lshake the fire, it is simply necessary to grasp the handle extension lQ'and oseillate the'grate with the pin 9 serving as a fulcriun point. If it is desiredv Vto dump thegrate, it is simply necessary to drawv the grate y outwardlythrough the space beneath the frontj wall and the contents of the fire-box may drop down upon the hearth. A grate for an open fire-place has thus been provided which can be easily andquickly put together or taken'apart if necessary.

l. A grate comprising a fire boX having a rear wall, a forward wall and end walls, a depending fulcrum element carried by said rear wall supporting' means carriedV by said end walls, and a bottom grate extending'beneath said forward. wall and Vresting upon Vsaid supportingmeans and having its rear edge portion vengaging said fulcruin to Y mount the grate for oscillating movement in a horizontal plane.
