To all 'aU/wm t may concern.'

Be it known that l JOHN K. OELSLAGER,

' tains to make and use the same.

This invention relates to tank heaters, and the primary object of the invention is to provide an improved means for shaking' grates,` so as to permit the ashes to be readily dislodged therefrom.

Another object of the invention is to provide an improved means for mounting the shaker rod in the tank heater so that the same may be quickly and readily removed therefrom when so desired.

A further object of the invention is to provide an improved tank heater having an inclined chute for permitting the ashes to be readily removed from the heater, the shaker being mounted in an offset guide way formed in the chute, so as not to interfere with the removal of ashes from they heater.

A further object of theinvention is to provide an improved tank heater having the upper portion thereof so formed, that the entire heater can be immersed in the water in the tank, so that a maximum amount of heat radiating surface may be engaged by the\water.

A still further object of the invention is to provide an improved tank heater of the above character which is durable and eflicient in use, one that is simple and easy to manufacture, and one that can be placed upon the market at av reasonable cost.

With these and other objects in view the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specificallv described, claimed and illustrated in the accompanving drawings, forming a part thereof, in Which:

Figure 1 is a vertical longitudinal section through the improved tank heater.

. Fig. 2 is a section taken on the line 22 of Fig. l.

Fig. 3 is a detail vie-w of'the shaker rod. Fig. 4 is a detail section taken on the line H of Fig. 1.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the numeral 1 indicates the improved tank heater which includes' the body 2 having the upper cylindrical portion 3 and the lower substantially rectangular portion 4, which forms the ash pit. The upper end of the body 2 is dome-shaped and provided with a smoke outlet 5. An annular flange 6 is formed around the smoke outlet and receives an ordinary stove pipe 7 having a damper 8 formed therein. An inner ange 9 is formed on the inner surface of the body 2 intermediate the cylindrical portion 3 and the rectangular portion 4 thereof, and the fiange receives the grate 10 yand forms means for permitting the grate to be moved. An inwardly extending pin 11 is carried by the body 2 and engages the upper surface of the grate at the rear end thereof and prevents accidental displacement of the grate. The grate 10 is provided with a radially extending lug 12, which is formed diametrically opposite the pin 11 and this lug extends outwardly of the body 2 into the inclined chute 18, which extends upwardly and outwardly from the lower portion i of the body and this chute communicates with the ash pit and forms means whereby the ash pan 14 may be readily removed therefrom. The lug 9 is bifurcatedas at 12 for receiving the lower end of the shaker rod 15, which will be hereinafter more fully described.

The rear wall of the chute 13 is provided with an outwardly extending offset portion 16, which forms a guideway for receiving the shaker rod 15 and also forms means whereby the shaker rod is positioned in rear of the inner face of the rear wall, so that the ash pan may be readily removed without contacting with the shaker rod or the lug 12. A supporting plate 17 extends transversely across the guideway 16 adjacent to the lower end thereof and is spaced from the rear wall of the guideway, and the upper edge thereof is provided with an inwardly extending notch 18, which receives the cylindrical bearing lug 19 formed on the shaker rod and this plate forms means for holding the shaker rod in correct operative position and permits the same to be readily oscillated for shaking the grate.

The shaker rod 15 has the lower end thereof inclined upwardly, as at 20, and gradually tapered toward the end thereof so as to permit the same to be readily inserted in the bifurcated portion of the lug 12. The shaker rod 15 is slightly enlarged adjacent to the inclined end and the cylindrical bearing 19 is formed on this portion. The inclined end 2O of the shaker rod conforms to the conguration of the lower portion of the meeting surface of the cylindrical body 3 and the offset enlargement 16. The upper portion of the shaker rod 15 forms an operating handle whereby the same may be readily grasp ed so that it can be swung on the supporting plate 17 and shake the grate. The upper end of the shaker rod 15 ends adjacent to the upper end of the chute and in a convenient position whereby the same may be readily grasped.

A removable cap 21 is provided for the upper open end of the chute 13 and the cap is provided with a reduced extension 22 for engaging the offset enlargement 16. The cap is provided with a pair of draft openings 28, and a slide plate 23 is mounted in the guideway 24 formed on the upper edge of the cap 21 and this slide has a pair of openings 21 formed therein which are adapted to register with the openings formed in the cap 21 when the plate is operated, so as to permit the entrance of air into the chute and below the grate when so desired. The movement of the slide 23 is limitedin the guide way` 24, by means of a depending pin 27 carried by the slide, which is slidably received in a slot 28 formed in the cap 21.

An angular chute 25 communicates with the body 2 adjacent to the upper end thereof and a suitable cover 26 is provided for the same. rIhe chute provides means whereby `fuel maybe fed into the heater.

As clearly shown in Fig. 1 of the drawings the heater is to be placed directly in the tank which is to be heated, so that the water therein may readily circulate around the outer surface of the heater.

From the foregoing description it can be seen that an improved means is provided for operating the grate which is so positioned in relation to the ash removing ehute, that the same does not interfere in any way whatsoever with the removal of the ashes.

In practice, I have found that the forni of my invention illustrated in the accompanying drawings and referred to in the above description, as the preferred embodiment7 is the most efficient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required without sacrificing any of the advantages of my invention as set forth.

/Vhat I claim as new is:

A tank heater comprising a body, a grate rotatably mounted in the body, an ash pit arranged below the grate, an outlet pipe communicating with the upper portion of the body, an inclined chute extending upwardly from and communicating with the ash pit, a cover for this chute, a longitudinally extending offset formed on the rear wall of the chute, and a rearwardly extending bifurcated lug formed on the grate and extending into the offset portion of the chute, a transversely extending plate secured in the oifset portion and spaced from the rear Wall thereof, and a shaker rod arranged to be positioned in the offset portion of the chute, the lower end of said rod being tapered and arranged to detachably ft in the bifurcated portion of said lug, and a cylindrical bearing pin formed on said shaker rod adjacent to the lower end thereof and arranged to detachably fit in said notch, as and for the purpose specified.

In testimony whereof I aix my signature in presence of two witnesses.
