FRANK S. BISSELL, OF STERRETT, ALLEGHENY COUNTY, PENNSYLVANIA.
GRATE.
SPECIFICATION forming part of Letters Patent No. 351,155, dated October 19, 1886.
Serial No. 178,111. (No model.)
To aZZ whom, it may concern.-
Be it known that I, FRANK S. BIssnLL, of Sterrett, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Grates; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part "of this specification, in which-- Figure 1 is a plan view of my improved grate. Fig. 2 is a similar view of the same when the gratebars are tilted to dump the contents of the grate. Fig. 2 is a perspective view of a part of one of the grate-bars and of the bar for tilting it. Fig. 3 is a front elevation of the grate, as shown in Fig. 1. Fig. 4 is a vertical cross section of the grate on the line :0 mof Figs. 1, 2, and 3. Fig. 5is a perspective plan view, partly in section, of the grate-bars and of the mechanism for reciprocating and tilting them. Fig. 6 is a plan view of a locking device which I employ for looking the tilting mechanism.
Like symbols of reference indicate like parts wherever they occur. I
My invention relates especially to grates for open fire-places, open fire-place heaters, or open fire-place stoves, but is generally applicable to cook-stoves, ranges, and other like places, where a light agitating and dumping grate is desirable.
It has for its object to obtain a dumpinggrate of that class wherein the fuel is agitated by a sliding or reciprocating motion of the bars, and is an improvement upon the device shown and claimed by me in Letters Patent No. 238,636, dated the 8th day of March, 1881.
I will now proceed to describe my invention more specifically, so that others skilled in the art to which it appertains may apply the same. I In the drawings, 2 indicates the main or fixed frame supporting the grate, which will of course vary, according to the class of grates to which the invention is applied.
4 1 represent sliding frames, which are mounted upon and supported by the main frame 2. In the drawings they are two in number, arranged side by side, each consisting of a hollow rectangular metal frame or casting. The grate-bars proper, 5, are fixed within secondary frames 6, also preferably of a hollow oblong form, and provided at their ends with trunnions 7, which fit within hearings on or in the body of the frames 4 4:. The frames 6 are made of proper size, and one is pivoted within each of the sliding frames, so as to be capable of oscillations therein.
8 is the agitating-bar or crankshaft, which has bearings on the fixed frame 2, and extends from one side of it to the other, transversely to the sliding frames 4 4 and underneath them. One of the sliding frames, 4, is provided with a downwardlyprojecting forked lug, 9, which straddles an eccentrieallysituate crank on the shaft 8, and the other sliding frame, 4,is c011- neeted with the shaft by an eccentric lug, 10, affixed to the latter and fitting within a notch or fork on the bottom of the frame. Owing to the construction specifiedviz., the sliding frames having their bearings one above and one below the center of motion of the agitating-shaft, reciprocating rotation of i the latter will cause the frames to slide backward and forward, thus effecting a thorough agitation of the fuel, which is superimposed thereon. The shaftS projects beyond the front of the grate, and is operated by a leverhandle, whose end is inserted into a polygonal socket, 1.1, in the projecting shaft, Fig. 5.
The grate is tilted by the following mechanism. (See Figs. land 2.) Each of the pivoted frames 6 has a downwardly-projecting arm or finger, 12, which is affixed to the bottom of its frame at the end thereof. These arms pass through somewhat elongated holes or slots 13 in a sliding bar, 14, which latter extends from beyond the front of the grate underneath the sliding frames 4 4, transversely thereto, and is supported by brackets 15 and 1.6,through which the bar may be moved in a right line backward and forward. If the bar be drawn forward into the position shown in Fig. 4, the effect will be to move the lever-arms 12 and to tilt the pivoted frames upon their axes within the sliding frames 4., thereby causing the body of the superposed fuel or ashes to fall into the ash box or pit beneath the grate. Pushing the tilting-bar 14 back into the position shown by dotted lines in Fig. 4 will restore the leverarms 12 and the pivoted frames into their normal positions.
It is evident that as the sliding frames 4 4 and their contained frames 6 are reciprocated by the shaft 8 the tilting-bar 14 will also be oscillated. This is permitted by slotting the brackets 15 and 16 longitudinally, as shown in Figs. 3 and 4. To prevent such oscillation from jarring the tilting-bar forward, and thus automatically upsetting the grate-frames, I provide the upper surface of the bar with a stud or boss, 17, and pivot to the front bar of the fixed grate-frame 2 a latch, 18, which may be moved up or down on its pivot, so as to rest upon or be separated from the tilting-bar. The
trically-pivoted cam, 20, the axis ofwhich traverses an upright slot, 21, in the latchand enters the face of the fixed grate-frame. By turning the cam 20 upon its axis its bearing within the yoke 19 will move the latch up or down to release or engage the stud 17, as desired, and will hold it with necessary safety in the position in which it may be left. The cam may be turned by a thumb-piece, 22, of ornamental design.
The construction being substantially as specified, the fuel upon the grate may be thoroughly agitated from the front for the removal of dust by means of the agitating-shaft 8, which, upon being oscillated, will impart a horizontal sliding or reciprocating motion to the grate-bars, and at any time the contents of the grate may be dumped by drawing the bar 14 and tilting the independent pivoted frames 6. The grate bars and frames are preferably held in place by means of coveringbars 23, which are secured to the fixed grate-frame advantages of the reciprocating or sliding bar grates for open fire-places, stoves, ranges, &c., of that class operated from the front without sacrificing any of the advantages pertaining to dumping-grates.
\Vhen my improved grate is used, if it should become partially filled with slate or clinkers, these can be readily removed without dumping the entire contents by drawing the tiltingbar 14 out far enough to partially upset the pivoted frames and to leave a space of suflicient area between their lateral edges and the sides of the sliding frames, and then shaking the grate, either by oscillating the shaft 8 or by' vibrating the tilting-bar.
I do not desire to limit myself to the use of two tilting or two sliding frames, since a greater number of each may be employed, and, if desired, more than one tilting frame may be pivoted within each sliding frame.
\Vhat I claim as my invention, and desire to secure by Letters Patent, is-
1. The combination, in a grate, of several with said frame, frames carrying grate-barspivotally mounted within said I reciprocating frame, a movable tilting-bar extending transversely to said tilting frame and connected therewith, and a movable lever-latch engaging. with the tilting-bar, substantially as and for the purpose specified.
4. The combination of a tilting grate or bottom, a tilting-bar, a movable lever-latch engaging with the tilting-bar, and a cam, 20,- bearing against a yoke on said latch, substantially as and for the purpose specified.
In testimony whereof I have hereunto set my hand this 3d day of September, A. D. 1885. FRANK S. BISSELL.
\Vitnesses: W. B. CoRwIN, THOMAS W. BAKEWELL.
