OPERATING MECHANISM FOR SHARING-GRATES.

Specification of Letters Patent.

Original application led September 13, 1915, Serial No. 50,293. Divided and this application filed November 1, 1915. serial No. 59,004'.

To all whom t may concern:

Be it known that I, Hann/[AN R. VEBER, a citizen of the United States, residing in the city and county ofDenver and State of Colorado, have invented certain new and useful Improvements in Operating Mechanism for Shaking-Grams; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the `art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in means for operating shaking-grates or furnaces of the class set forth in my former application, Serial No. 50,293, led September 13, 1915. In fact, the subject matter of my present invention is 'divided out of that originally set forth in the aforesaid application.

The means for shaking the grate bars, consists generally speaking of an exteriorly located lever fulcrumed on a bracket secured to the front wall of the furnace, the lever being connected with the grate bars through the medium of connecting rods and lever arms, the latter being formed upon the grate bars and extending downwardly therefrom.

My present invention also includes means for operating the pivotally mounted burner plate located in front of the grate proper which forms the subject matter of my previous application.

Having brieiiy outlined my present construction, l will proceed to describe the same in detail, reference being made to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing-Figure 1 is a section taken through the fire box of a furnace suit-v able for a water tube boiler. ln this view the grate bars are shown in the closed position, the operating mechanism being connected therewith. Fig. 2 is a similar view showing the grate bars in the dumping position and the operating mechanism correspondingly arranged. Fig. 3 is a side elevation partly in section of the shaking lever and its supporting bracket, employed in operating the grate bars. Fig. 4 is a section taken on the line 4-4, Fig. 3. Fig.l 5

is a fragmentary sectional view of the front part of the furnace, being similar to Figs. 1 and 2, but shown on a larger scale.

The same reference characters indicate the same parts in all the views:

Let the numeral 5 designate the fire box; 6 the ash pit; 7 the bridge wall; and 8 the grate of a furnace with which my improved operating mechanism is adapted to be used. As illustrated in Figs. 1 and 2 it is assumed that the furnace is employed with a water tube boiler, a number of tubes 9 being illustrated. It must be understood, however, that the operating mechanism is adapted for use with shaking-grates of all kinds. In other words, it is capable of general application.

As illustrated in the drawings, the grate bars which are designated by the numeral 10 are transversely arranged being provided with trunnions 12 which engage sockets formed in trunnion bars 13.

Each grate bar 10 is provided with a downwardly extending lever arm 22 having a perforation 23 adapted to be connected by means of a pin or bolt 24 with a rod 25 having an extension 26 passing through an opening 27 in the front wall of the furnace, the forward extremity of the rod be.- ing pivotally connected as shown at 28 with the lower extremity of a shaking lever 29, the latter being fulcrumed on a bracket 30 by means of a pin 31 threaded at its opposite extremities to receive nuts 32, the said pin passing` through registering perforations formed in the lever and bracket. The upper part of this lever through which the pin 31 passes, as illustrated in the drawing, is circular in shape and designated by the numeral 33. v This lever is provided on one side with a circular socket 34 adapted to receive a counterpart ring 35 formed on the bracket 30 whereby the lever is accurately guided when actuated for grate shaking purposes. This-part 33 of the lever is provided with two

taper sockets

36 and 37 adapted to receive a handle 38 whenever it is desired to manipulate the lever for grate shaking or dumping purposes. The socket 36 which isnearer the front wall of the furnace, is used when it is desired to shake the grate. In this event the handle cannot be moved far enough forwardly for dumping purposes. When it is desired to dump the grate, the handle is placed in the socket 37 which permits sufficient range of movement for the purpose, as indicated by the two positions of the lever and handle in Fig. 5, one of these positions being in full lines and the other in dotted lines. The circular part 33 of the lever is provided with a perforation 39 adapted to register with a number of perforations 40 formed in the part 41 of the bracket 30, whereby the lever may be locked in the desired position by the employment of a movable pin 42 having an eye 43 with which a chain 44 may be connected for retaining the pin in place in suitable proximity to the lever. The bracket 30 1s provided with a flange 45 which vfits the front wall of the furnace and is secured thereto by bolts 46 or other suitable fastening devices, nuts 47 being applied to the bolts for fastening purposes.

Forward of the portion of the grate composed of the grate bars 10 is located a transversely arranged burner plate 60 whlch 1s inclined downwardly from the inner surface of the front wall of the furnace. The forward extremity of this plate is equipped with trunnions 61 which engage sockets formed in suitable supports as trunnion bars. This plate is normally supported by a transversely arranged block 62 whose eX- tremities slidably engage ledges 63 formed on the trunnion bars or other suitable supports. Connected with this block 62 is a rod 64 which extends through an opening 65 formed in the front wall of the furnace beneath the fuel opening 76. The outer eX- tremity of this rod 64 is pivotally connected as shown at with a manipulating lever 66 which is fulcrumed at its lower extremity as shown at 67 on a stationary lug 68. When it is desired to drop the burner plate to facilitate'the removal of clinkers or ash, the supporting block 62 is moved forwardly as indicated by dotted lines in Fig. 5. In

this event the burner plate will drop to the position indicated by dotted lines in the same view, whereby a relatively large opening forward of the grate proper is formed, said opening being of suiiicient size to permit the passage of the largest clinkers. By moving the lever 66 to the rearward or full line position in Fig. 5, the burner plate supporting block 62 will be moved rearwardly and the said plate restored to its normal position.

From the foregoing description it is belived the construction of my improved mechanism for operating shaking-grates will be readily understood. It is assumed that the grate as illustrated in the drawing will consist of a number of sections, each section being composed of a single burner plate 60, a number of grate bars l() located in the rear thereof, a shaking lever 29 connected in operative relation with the grate bars of the section, and a single lever 66 for adjustin the block which supports the burner p ate.

Assuming that the grate is assembled as heretofore described, when it is desired to shake the same, the handle 38 which may be considered as removed after each shaking act, is inserted in one of the taper sockets. If it is only desired to shake the grate, the handle will be placed in the socket 36, while if it is desired to dump the grate, it will be placed in the socket 37. It will be understood that when the shaking lever is in the position shown by full lines in Fig. 3, that the grate is closed whereby the fuel engag ing surfaces of the bars are in the horizontal position and t closely together (see Fig. l). Now, if it is simply desired to shake the grate, the handle 33 will be inserted in the socket 36, in which event the shaking lever when at its forward limit of movement will occupy approximately a position midway between the positions indicated by full and dotted lines in Fig. 3; and after the shaking is completed, the grate bars will be restored to the position shown in Fig. l. Again, if it is desired to dump the grate or throw the grate bars to the position shown in Fig. 2, the handle will be inserted in the socket 37. In this event the handle will be permitted to move forwardly a sufficient distance (see dotted lines in Fig. 5), to throw the lower arm of the lever 29 also to the dotted line position in the same view, when the grate bars will be in the dumping position indi cated in Fig. 2 where the handle 38 is shown in full lines in the position for dumping purposes, When the grate bars are in the dumping position, if there are any clinkers or other material too large to pass through the openings between said bars, the support ing block 62 for the burner plate 60 may be moved forwardly (see dotted lines in Fig 1) allowing the burner plate to drop downwardly far enough to make a suliicient open.- ing for the removal of the largest clinkers. This supporting block 62 is shifted through the instrumentality of the lever 66 and the connecting rod 64 as heretofore explained.

Having thus described my invention, what I claim is 1. The combination with a grate having pivoted bars, of means for operating the said bars for shaking or dumping purposes, comprising a lever having a disk member, a bracket having a coperating disk member, the latter having a series of perforations therein and the disk member of the lever provided with a perforation adapted to register with the perforations of the said bracket disk member, means adapted to be inserted through said registering perforations for locking the lever in the desired position, the disk member of the lever also having openings in its periphery, and a handle adapted to enter said openings for operating purposes.

2. The combination vvith a grate having 5 pivoted bars, of means for operating the .said bars for shaking or dumping purposes., comprising a lever having a disk member, a bracket having a coperating disk member, the latter having a series of perforations therein and the disk member of the lever provided With a perforation adapted to register With the perforations of the said bracket disk member, and means adapted to be inserted through said registering perfo- 5 rations for locking the lever'in the desired position, one of the said disk members having a bearing ring and the other a recess to receive said ring and a fulcrum pin connecting the said elements, the said ring being concentrically arranged around said pin,the disk member of the lever also having openings in its periphery and a handle adapted to enter said openings for operating purposes.

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