To all whom t may concern:

Be it known that l'., Ennivnznn A, W. JEF- rnnins, a citizen of the United States, residing at lVoicester, in the county of `Worces ter and Cnnmonwealthv,v `of Massachusetts, have invented a new and useful Improvevment in Gas-Producers of which the' following, together with the accompanying drawings, is a specification.

2.5. ing

My present invention relates tothat class of gas producers which comprise a rotatable support for the .ashes spaced beneath the body portion of the gas producer, said ash support having a radial arm or scraper resting upon the bottom of the ash support and Journaled concentrcally with said ash support, with means for holding said radial arm stationary while the ash support revolves beneath it, thereby causing the ashes to be crowded outwardly and delivered from the edge of the ash support. I

The objects of my present invention are to provide means for engaging the outer end` of the radial arm or lscraper and for automatically releasing said scraper, allowit to 'rotate with the ash'support and l ,thereby interrupt Athe discharge of ashes plan view of the lash support and scraper with mechanism for automatically releasing the latter. Fig. 3 is a Vertical sectional view of a portion of the gas producer, showing a side view ofthe apparatus for automatically releasing the ash scraper. Fig. 4 is a detail4 view of the latching mechanism forl'atop-T ping the rotation of the ash scraper. Figs. 5 and .6 are detached views of the mechanism for Aautomatically releasing the ash scraper,`

and Fig. 7 shows a modification of the autog matic scraper releasing mechanism.

Similar reference characters refer to si'r'ni.;`

lar parts in thedifferent figures. Referring to Figs. 1 `and 3 of ings, l denotes the body portion of a gas producer inclosing a gas producing chamber anddspaced above a rotatable ash support 2 consisting, in the present instance, of a shallow pan into which the ashes are delivered from the body portion of the producer through its open bottom.' The ash support 2 is mounted upon rollers 3, 3 and is rotated by a rotating pinion 4 engaging an annular rack 5 upon the ash support. 4concentrically with the rotating ash supportf 2 1s an ash scraper 6, resting upon the bottom of the ash support and consisting, in the present instance, of a helical shaped arm having its outer or free end 7 arranged to be engaged by a latch 8 lpivoted at 9 upon the lower end .of an arm 10 rigidlyattached to the fixed walls of the gas producer and eX- tending downwardly toward the ash support. By reason of its frictionalengagement with the bottom of the ash support, the scraper r6, when not engaged by the latch 8, rotates with said ash support. The upper end of the latch 8 is connected by a link 11 with a short arm 12 carried upon the in- Journaled ner end -of a rocking lshaft 13. Attached to the outer end of the` rocking shaft 13 is a lever 14' supporting upon itsfree end an adjustable counterweight 15. The lever'14 is connected by a link 16 withA one end of a lever 17 turning loosely upon a shaft 18 supported in brackets 19 upon the top wall of the gas producer. Journaled upon the shaft y 18 is' a lever 20 carrying upon one end an adjustable counterweight21., which is normally supported uponv a stop or rest -22 by which the lever 20 is maintained in a horizontal position. The opposite` end ofthe lever 20 is pivotally connected by a link 23 'with a radial arm 24 attached to one end the rocking shaft 25 carries ai radial arm 26 in the free end of which is a cam roll v27. Attached to the outer wall of the ash supof a rocking shaft 25. The opposite end-of port 2 is a cam 28, said cam roll 27 being arranged in the path of the cam 28 as the latter is carried around by the rotatable. ash

support 2. Extending upwardly from the rockinglever 20 is a short arm 29, upon the weight 31 and .provided with an Vvarm 32 which carries thereon an adjustable counter weight 33. The lever 17 is provided with a' notch 3 4 adapted to. receive the end. 35 of lthe pawl 30 as shown in Fig. 6,- upon the op- .eratlon of the. mechanism in the manner hereinafter described.

, With the lever y14 in the position shown in Fig. 5, the latch 8 is disposed so as toy bring its' lower end 36 into the 'path of the Y scraper 6, and it will be understood, that if said latch be so held, the advancing end 7 of the scraper will be engaged thereby,'caus ing said scraper to be held from rotation.

The continued rotation of the-ash support,

withv the scraper thus held from rotation carries the mass of ashes againstthe helical lside of the scraper, causing such ashes to be pushed outwardly and crowded over the Haring-side ofthe pan.

tation of the scraper 6 with the ash support and consequently interrupts the discharge of liashes from said support. The several movements of latch 8 are controlled by the cam 28 inthe following manner: The cam 28 as it is carried around by the rotating ash support will ride over the camroll 27, depressing the arm 26 and rocking theshaft 25. 'The rocking of the shaft 25 through' the radial arm 24 and link 23 will rock the lever 2 0 on the shaft 18 from the position shown in Fig.' 1- to that represented in Fig. 5, wherebythe pawl 30, which it will be as- `gsulned, has been caused to occupy the position shownin Fig. `1, will tip' over tothe right, with its end resting against theextreme end of the lever 17, beyond vthe notch 3 4 of the latter, as shown in said Fig. 5. When the cam "284 passesA the cam roll 27 the counterweight will reverse the motion of the lever 20, restoring it .to the position shownin Fig. 1,.allowing the end 35 ofthe pawl 30 to engage the notch 34 in the l lever 17. In this position of the pawl 30,

- the next .passage of the cam 28 lover the cam roll 27 will again rock the shaft 25, de-' p'essing'the arm V24 and againrockingthe lever 20 through "the link 23 into the position shown in Fig. 6. At this rocking move- .ment of the lever 20, however, the engage- Inent of the pawl 30 -with the lever 17 will lift the lever 14 through the-link 16, thereby rocking the shaft 13 and, through the radial arm 12 and-link 11, rocking theglatch 8 into 56 the position 4shownin Fig. 6.. The, lifting o`f the latch 8. into this position .permits the passage thereunder ofthe scraper, provided `said scraper is in radial alinement with the cam and arrives adjacent the latch when the 0 latter is in raised position. If such is not the case, as happens .when the device is first put into action, the subsequent arrival of the scraper finds the latch depressed, owing to the movement of the cam 28 past the roll 27. The depressed latch holdsthe scraper The subsequent movement of latch 8 int'-.- 1 the position shown in Fig. 6 permits the rostationary until the cam 28 again engages the roll 27, moving the latch into the position shown in Fig. 6 and permitting rotation of the scraper. Thereafter the cam and scraper rotate together, the latch 8 being 70 raised at each revolution to permit the -passage of the scraper thereunder. When it is desired to make the scrapereilective again to discharge ashes from thc support, the op' erator rocks the pawl 30 toward the left, 7'5 from the position shown in Fig. 6 to that shown in Fig. 1. When the cam 28 again comes into contact with roller 27,.the lever; 2O is moved downward as shown in Figli), without carrying with it the lever 17, there- Q. '80 by leaving the latch 8 in position to arrest the rotation of the scraper. .During the following rotation of the'ash support, ashes are therefore discharged, unless there arises a force tending to move the scraper, sufficient 35 to raise the counterweight' 15, the 'latter be ing made heavy enough to hold the scraper vfirmly to its work.- Should such a force.

arise, due to the jamming of a mass ofn clinker between the scraper and the wall of the support, or to any other cause, the latch is forced upwardly against the action of the counterweight and-the scraper continues to rotate until the force is removed. When the cam again comes into contact with then roller 27, the pawl 30 has assumed the position shown in Fig. 6, and the release of the scraper is eilected. The interruption to the discharge of ashes continues until theoper-` ator` again rocks the pawl 30 to the'leftl 1 00 when the above described operation.4 is re#` peated. It will be 'obvious that mre than one cam may be used, so that the interruption to the discharge of ashes, which by the4 above described apparatus is automatically effected after one revolution of the support,

. may be effected at shorter intervals.

Ain pivoting uponthe shaft 18 a lever 37 hav- 115 I ing a series of notches 38 in one end, in the present instance three in number, and having its opposite end provided with a pin 39 which extends through a slot 40 formed in the link 16. apable of sliding in the slot 120 ,40 is a block'41`,the .position of which may be adjusted in the slot'40 by means of a screw 42. The lever 37 is provided 'with a split bearing which incloses thesh'aft 18.

This bearing is provided with a bolt 43 by 125 which the lever 3 7 Vmay be vclamped upon the shaft 18 to produce a slight frictio'suiiicient to prevent it from being rocked upon theshaft 18 by its own weight. By adusting theblock 4l in the slot 40, the link 16 13 ineens? and lever la may be lifted by the engagement of one or more of the ntches 38, causing one, two or three revolutions of the ash support to take place before the release of the scraper 6 occurs.
