TED STATES PATEN T @FFTfiEt CARLTON W. KINNEAR, OF COLUMBUS, OHIO.
FEEDING DEVICE non UNDERFEED STOKERS.
Specification of Letters Patent.
Patented'Feb. 21 1911.
Application filed November 7, 1910. Serial No. 591,145.
To all whom it may concern."
Be it known that I, CARLTON W. KIN- aznxn, a citizen of the United States, resid- -ton or plunger; the provision of an auxiliary feed plunger provided with means for agitatii'ig the fuel above the plunger and preventing packing; and the provision of an auxiliary feed plunger designed to secure both more effective forward feed and an agitation of the fuel .in the trough. One embodiment of the inventionvis illustrated inthe accompanying drawings, .wherein' Figure 1 is a longitudinal section through the center line of a trough having the improved construction, and
Figure 2 is a section on the line II-II of Figure 1.
The invention is shown as applied to the underfeed trough of alocomotive stoker, butit will be understood that the device is of general application. In the construction -as illustrated and as shown in the drawings, 1 is the water leg of the fire-box; 2 isthe trough extending longitudinally of the furnace; 3 and 4 are auxiliary feed plungers working in the plunger guideways 5 and 6 formed in the bottom of the trough; and 7 and S are links pivoted to the plungers and operated from power mechanism not shown. The upper walls of the plunger guideways are slotted at 9 and 10, and the agitating blocks 11 and 12 are secured to the upper sides of the plungers 3 and 4 and are mounted for movement in the slots. As indicated'in Fig. 2, the agitating blocks are provided at their lower portions with shanks fitting the slots while the upper portions are of greater width and have rearwardly inclined upper faces. The blocks are held in position by means of the bolts indicated.
The blocks 11 and 12 serve as agitating means for preventing the fuel from packing inthe trough above the plungers and also assist in giving a forward feed to the fuel. The block 12 also serves to loosen the fuel immediately in front of the plunger 3, so
that a more elfective feed of such plunger 3 is secured, and similarly the block 11 serves to loosen the fuel in front of the main plunger.
7 Having thus described my invention and illustrated its use, what I claim as new and desire to secure by LettersPatent is the following I l. The combination of an underfeed trough, a plunger guideway at the bottom thereof opening at its forward end into the trough and having a slot in its upper wall, and a fuel feeding plunger mounted for reciprocation in the said guideway, and provided upon its upper face with a fuel agitator working in the said slot.
2. The combination of an, under-feed trough, a plunger guideway at the bottom thereof opening at its forward end into the trough and having a slot in its upper wall, a fuel feeding plunger mounted for reciprocation in the said guideway, and a fuel agitator upon the upper side of the plunger having a shank working in the said slot and a head of greater width than the shank lying'abovethe said slot.
3-. The combination of an .underfeed trough, a plunger guideway at'the bottom thereof opening at its forward end into the trough and having a slot in its upper Wall, a fuel feeding plunger mounted for reciprocation in the said guidewa and a fuel agitator block working in sai slot, and detachably secured to the plunger.
4. The combination of an underfeed trough, a plunger guideway at the bottom thereof opening at its forward end into the trough, a fuel feeding plunger mounted for reciprocation therein, a second plunger guideway to the front of the first guideway opening,at its forward end into the trough and having a slot in its upper wall and a fuel feeding plunger mounted for reciprocation in said second guideway and provided upon its upper face with a fuel agitator working in the said. slot and in its rearmost position lying adjacent the front en'dof the first mentioned plunger.
In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
CARLTON w. KINNEAR.
