Application led March 15, 1905.. SerialNo. 250,242.

To M whom/'zit may concern:`

Be it known that l, JOHN LOFTUs, a citizen lof the United States, residing at Albany, in

the county of Alb any and State ofNew York, have invented certain new and useful Improvements. in Stove-Grates; and 'I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable-others skilled in the art to which it aplpertains to make and usethe same, reference eing had to the accompanying drawings, and to the letters of reference marked'thereon, which form a part of this speciiication.

This invention relates to grates for .cookstoves, and especially to inexpensive means for removing the ashes fromthe iire-chamber without a back and forward movement ofthe grate and also for making the grate curved, as shown in Figures 1 and 2, so as to allow the iire in the fire chamber to be close to the oven-plate, causing a large amount of heat to radiate from the grate to the oven. fr

Furthermore, the inventionprovides a lurality of arms mounted uponarocking sto ershaft,-which is disposed across the stove at the dividing-line of the nre-'chamber and ash- Apit and at' the lower point of the grate, said members being provided with sector ends adapted to move between the bars of. the grate for the purpose of stirring -the iire and allowing the ashes and cinders to drop therethrong.`

This invention may valso be adapted for use in connection with steam-heating appa-` ratus.

To these ends and to such others as the invention may pertain the same consists in the novel arrangement, adaptation, and combination of features, which will be hereinafter more fully described and then pointed out in the appendedclaims.

The invention is illustrated inthe accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, such letters of reference indicating like'parts inthe views, in which- Fig. 1 is a side elevation ofa cook-stove, partly in section, showing the improved grate in position. Fig. Z-is a pers ective view of the grate and arms removed t erefrom. Fig'. 3 is a fragmental perspective view of the grate, showin the engagement with the lower end of t e abutment-plate. Fig. i is a detail view of one of the rocking members.

Fig. 5 is a detail perspective view of the rear supporting-bar. Fig. 6 is a detail sectional viewof one of the bearing-blocks for the ends of the shaft. Fig. 7 also is a detail erspective view 'of a bearing-block employed) at each end of the shaft. Fig. 8 is a sectional view on line 8 8 of Fig. l llocking in the direction of the arrow. Fig. 9 is a side elevation of a cook stove, partly in section, showing a slightly-modified form of grate. Fig. 10 1s a perspective view of theY form shown in Fig. 9,'

and Fig. 11 is'a fragmental perspective view of the form of grate shown in Figs. 9 and 1 0, showing the engagement with the lower end of the abutment-plate. Reference now being' had to the detailsof the drawings by letter, A representsl an ordinary cook-stove, having located in the usual Patented March 20, 1906.

place agrate'B, composed of a plurality of ars C, said bars being integral with the rear 'bar Cf, vextending at right angles to the bars B. Located adjacent yto the casing of the front portion of the stoveis an abutmentplate D, having on each end thereof bars D f projecting downward and having notches D2 adapted to receive the ends of the end bars D3 of the grate.- The bars of the grate are recessed, as at E', to allow arock-shaft E to rotate freely therein. and, the bars D4 adjacent thereto have their edges near their ends beveled, as atD5, to provide a bearing for bearing-blocks D. -Said bearing-blocks are Vrovided lwith apertures D7, which are slig tly larger in diameter than the rock-shaft inorder to allow said shaft to have a slight play, so that clinkers or other'obstructions wi l not prevent the shaft from being rocked.L The ends of saidv shaft are4 circular in cross-section for the purpose of having a bearing in the side ofthe casing Y Vof the stove and also to4 allow the shaft to rO- tate smoothly. E2 designates an operatinghandle at one end of said shaft. Mounted upon the square portion of the shaft is a plurality of rocking members FX, having arms F lat their upper ends, the normal positions of The two end bars D3.

loosened as the shaft carrying the same is rocked. Said arms F are designed to contact with the abutment-plate D, whereby their throw in one direction is limited.

To firmlyhold the end bars D3 and the bars D4 together, the grate when cast is provided with integral joining-webs G. To prevent the bars of the grate when said grate 1s in position from being laterally bent, a toothed supporting-bar Gr is provided which extends across the fire-chamber at right angles to the bars of the grate. The sides of each bar are slightly inclined, as shown in Fig. 2 of the drawings, said inclined sides being adapted to rest in or engage the inclined spaces between the toothed bar G. Thus by reference to the drawings it will be clearly understood how the bars are prevented from being laterally bent.

Located at each end of the fire-chamber is the usual fire-brick or casting H, and adj acent to said fire-brick is a plate H', which is provided with a rib H2, which is adapted to hold the abutment-plate from falling rearward when the fire-chamber is empty.

The operation of the device is as follows: When the handle E2 is turned in the direction of the arrow, the arms F will be thrown outward and downward, which will allow a cer tain amount of the ashes and clinkers to fall from the nre-chamber, and at the same time that the arms are being thrown outward and downward the sector-shaped ends F will be thrown upward, which will thoroughly stir the fire.

Of course it is distinctly understood that various changes in the details of construction and combination of parts other than those illustrated in the accompanying drawings may be made, if desiredfwithout in any way departing from the spirit and scope of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with a grate, bearing- Ablocks mounted thereon near the front of the grate and adapted to have a slight play, a rock-shaft mounted in said blocks, a series of l members secured to said shaft, the lower ends of which are sector-shaped, and their other mounted between the bars of the grate, and adapted as the shaft is rocked to cause the clinkers and ashes to be loosened from the grate, as set forth.

2. In combination with a grate, bearingblocks mounted thereon near the front of the grate and adapted to have a slight play, a roclvshaft mounted in said blocks, a series of members secured to said shaft, the lower ends of which are sector-shaped, and their other ends formed into arms, said members being mounted between the bars of the grate and adapted as the shaft is rocked to cause the clinkers and ashes to be loosened from the grate, an abutment-plate to limit the inner throw of said arms, and a notched plate spacing and bracing the grate-bars, as set forth.

3. In combination with a grate, bearingblocks mounted thereon and adapted to have a slight play, a rock-shaft mounted in said blocks, a series of members secured to said shaft, the lower ends of which are sectorshaped, and their other ends formed into arms, said members being mounted between the bars of the grate and adapted as the shaft is rocked to cause the clinkers and ashes to be loosened from the girate, and a notched bar spacing and bracing the grate-bars, as set set forth.

4. In combination with a grate, means for supporting the same, bearing-blocks provided with apertures and having beveled edges adapted to have a play upon the bars of the grate, a roclcshaft mounted in the apertures in said bearing-blocks, a series of members secured to said shaft between the grate-bars, and having their lower ends sector-shaped, and their opposite ends upwardly turned, as set forth.

In testimony whereof I hereunto aiiix my signature in presence of two Witnesses.
