l 1 claim.' (ci. 19s-224i This invention relates to an ash-conveying means and lhas for one of its objects the production of a simple and eiilcient conveyor for automatically removing ashes from the ash-receiving compartment of a furnace'to a distant point of disposal. L

Other objects and advantages of the present invention will appear throughout the following specication and claim.

In the drawing:

Figure 1 is a'fragmentary front elevational view of a furnace illustrating the ash-removing mechanism, the ash-removing housing being shown in longitudinal section;

Figure 2 is a longitudinal sectional view taken on line 2-2 o f Figure l, a portion of the housing being shown in top plan;

. Figure 3 is a longitudinal sectional view of a portion of the ash-removing frame;

Figure 4 is a fragmentary sectional perspective view of a fportion of the ash-removing frame'. illustratingfthe manner of connecting the ends porting thejurnace 40, the housing 4| extend- -y ing laterally Vof the furnace 4|, as shown in Figure 1. Thermostats 42 and 43 are suitably located to control the motor 44 which accelerates the driving-i` mechanism of the shaking and grateoperating mechanism The thermostat 42 -is preferably-placed adjacentthe base of the furl nace 40. Trap doors 45 are conveniently located in the top ofthe housing 4| near the furnaceto permit access to the housing 4| adjacent the grate. A grate 46 is supported below the furnace within the housing 4|. A shaker grid 41 is slidably mounted over the grate 46 for reciproeating movement. The grid 41 is provided with parallelfarms 48 at one end and similar arms 49 at its opposite or formed end. The arms 48 work between the rollers 50 at one end of the housing 4| and thearms 49 work between the rollers` 5| at the opposite end the housing 4|. Comb rakes 52 and 53vv are suspended from the top of the housing 4|I at opposite sides of the furnace'flll to prevent large cakes of ashes from passing beyond the grate 46 and falling upon the ash'- conveyor mechanism below. These cakes, if any, will be broken-up as the grid reciprocates and the cakes of ashes are thrown against the 2 grate 46 and is actuated by links 55 from the operating crank 56, the grid 41 also being actuated simultaneously therewith by suitable links such as the link 51 shown in Figure 2, connected to the crank 56. The crank 56 is driven by the drive mechanism 51 from the motor 41 or other suitable power elements.

Itshould be noted that the flanged ends 6l fit nat against the transversely spaced upper and lower side rails to brace the ends of the raker plates and to firmly hold the raker plates between the transversely spaced side rails.

The ash conveyor 54 comprises a pair of lower longitudinal side rails 58 which rest upon and are anchored upon the base of the housing 4|, and a pair of upper side rails 59 which are slidably mounted on the lower rails 58. The upper rails 59 are connected at one end to the links 55, which links 55 are also connected to the crank 56. These rails 58 and 59 are connected transversely by the raker plates 60. Each raker plate 60 is provided with anged ends 6l. Each anged end 6| is provided with a longitudinal slot 62. Bracing rods 63 extend transversely between the upper rails 59 and pass through .the upper ends of the slots 62 to suspend the raker plates 60 between the rails 59. Pins or other securing elements 64 are located near the upper edges of the lower rails 58 and pass through the slots 62 adjacent the rods 63. As the upper rails 59 are pulled toward the crank 56 or in the direction shown by the arrow in Figure 3. the raker plates 60 will move from a substantially vertical to a substantially horizontal position, and when the plates 60 are returned to a vertical position by the further rotation of the crank 56, the ashes which may have fallen upon the plates 60 or which may be between the adjacent plates will be pushed toward the discharge outlet 65 of the housing 4L As this operation continues, the ashes in the rear Will push the forward ashes toward the opening 65 and cause a continuous stream of ashes to be moved longitudinally of the ash conveyor 54. The swinging plates 60 will cause the ashes to be moved longitudinally of the ash conveyor 54 by a pushing and tossing action as the plates 60 swing from a horizontal to a vertical position as the upper rails 59 reciprocate over the lower rails 58. The discharge end 66 is provided with a top gate 61 which may be swung upwardly so that access may be had to the interior of the discharge end 66. An outer end gate 68 is also provided as shown in Figure 1 to facilitate access to the discharge end of the housing4l.

Having described v the claimed as new is:

A mechanism of the class described comprising a. housing, an ash-conveying means comprising a pair of lower longitudinal transversely spaced side rails, a base supporting said side rails, a pair of upper parallel transversely spaced side rails slidable upon the first mentioned rails, actuating means connected to said upper side rails, a plurality of transversely extending rakerplates extending between the transversely spaced side rails, each raker plate having opposite anged ends tting at against the transversely spaced side rails to brace the ends of the raketv platea, each ilanged end having a longitudinal slot, guiding means carried by the opposite upper rai-ls'and extending through the upper ends. of `Said slots4 to suspend the raker plates between the opposite invention, what is rails, connecting means located near the upper the movement when the upper side rails are moved longitudinally in the opposite direction.
