' Specificati on o f Letters Patent. Patented Feb. 22, 1921.
Application filed January 30, 1919. Serial 27 4,05li.
To all whom it may concern: V
Be it known that I, GEORGE W. Howns, a citizen of the United States, residing at Dowagiac, county of Cass, State of Michigan, have invented certain new and useful Improvements in Grates for Furnaces, of which the following is a specification.
This invention relates to improvements in grates for furnaces. j
The main object of this invention is to provide an improved grate having rocking grate bars operatively connected by means,
of pinions in which the several grate bars may be quickly and easily placed inposition in assembling or removed and replaced as occasion may require for repairs. V
A further object is to provide a structure having these advantages which is simple and economical to produce and at the same time strong and durable. I
Further objects, and objects relating to structural details, will definitely appear. from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification. The "invention is clearly defined and pointed out in the claim.
A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which: t
Figure I is a detail view of a structure embodying the features of my invention, only such parts of a furnace being shown as are deemed necessary to illustrate an application of my improvements.
Fig. II is a detail transverse section on a line corresponding to line 22 of Fig. I.
Fig. III is a front elevation of the front bearing member and the retaining bar, the retaining bar being shown in its disengaged position. i Y
In the drawing similar reference charac' ters refer to similar parts throughout the several views.
Referring to the drawing, 1 represents the ashpit body of a furnace. The grate bars 2 are shown conventionally and are provided. with journals 3: at their rear ends and ,4 at their front ends. One of the grate bars is extended at 5 to receive a shaking crank.
At the-rear of the ashpit are bearings 6 with which the rear journals 8 of the grate I bars may be engaged and disengaged by a I longitudinal movement. The front ends of the grate bars aresupportediby the bearing member 7 having bearings 8 therein with slots9 extending from the bottom of the member and opening into the sides of these bearings 8. The edges 10 of these slots and bearings are preferably scroll-shaped as illustrated, as this facilitates the engaging and disengaging of the journals with the bearings and the bringing of the pinions 11 into and out of mesh as the grate bars are inserted or removed. The journals of the grate bars are retained in their bearings by means of the retaining bar 12 which is pivoted atone end of the bearing member, as at 13, and detachably secured at the other end by means of the pin 14; arranged through'holes ,15 in the bearing member and 16 in the retain ing member.
The retaining bar when in its closed or operative position'extends across the slots 9 closing the same and thereby preventing the disengagement of the journals; This retainingv bar is provided withnpwardly projecting lugs 17 which engage the outer sides of the journals limiting their lateral movement in the bearings, the lugs constituting, in effect, the side members of the bearings. The bearing member 7 is secured to the ashpit body 1 by means of bolts 18.
With this structure and arrangement of parts they maybe economically produced and very conveniently assembled or disassembled asoccasion may require.
In the accompanying drawing the various parts are shown mainly in conventional form as the structural details of the ashpit body and the grate bars, other than the inatter of their journals and the supports therefor, is not a matter of importance.
Having thus-described my invention, what I claim as new and desire to secure by Letters Patent, is:
The combination with a body member,
grate bars having journals at their ends and j provided. with meshing pinions, rear bearlugs for the rear ournals of the grate bars. a. front bearing member supportedby said body member in front of said pinions and having a series of bearing'openings there journals therein and the meshing and disengaging of the pinibn's by, at lateral movement in the same direction, and a, retaining bar mounted on said bearlng member to close sald slots, said retain ng barbeing pro- ,vided with upwardly prqjecting lugs constituting bearing members, for the outer sides of said journals and whereby they are retained in their bearingsrl l A In witness whereof, I 'hai'le hereunto set my hand and seal.
