AUTOMATIC DAM PER.

SPECIFICATION forming part of Letters Patent No. 445,113, dated January 20, 1891.

Application filed April 23, 1890. Serial No. 349,202. (No model.)

To al?, whom 15 may concern:

Be it known that I, FRIEDRICH OTTO H- BENZ, a subject of the Emperor of Germany, residing at RadebeulDresden, in Saxony, Germany, have invented certain new and useful Improvements in Apparatus for Regulating and Cont-rollin g the Admission of Air to Flues and Passages of Boilers or other like Heating Apparatus, of which the following is a specification.

The regulating apparatus consists in a clockwork, the movement of which effects a gradual automatic closing of the draft-dam per during the period from one charging to the other. This regulating apparatus is combined with a controlling device which warns the stoker at the end of each combustion period and yields an automatic record both as to the end of each combustion period and when the fireman has again wound up the regulating device.

This invention is represented on the annexed drawings, in which-e Figure 1 showsa frontview ofthe clock-work. Fig. 2 illustrates a way of transmitting the motion from the clock-work to a throttle-valve arranged in the line. Fig. 3 shows a side view, and Fig. a front view, of the clock-work. Fig. 5 represents the oontrollin g device in a larger scale, and Figs. G to 8 represent various means of transmitting the motion from the clockwork to the draft-damper.

A wheel C is iiXed on the axis c of a clockwork, Fig. 1. The latter is driven by means of the weight F, the string or chain f of which is wound on the drum E of the axle o. (See Fig. 3.) The clockwork may be of an ordinary kind, such as is, for example, represented in Figs. 3 and et.

The axis a of the throttle-valve A, Fig. 2, is provided with a double armed lever I3. Two chains b and b engage at the ends of said lever. The chain b is fixed to the wheel C and the chain b is fixed to a segment D, arranged on the side of said wheel C. At the running down of the clock-work the chain o is wound upon the segment D. In this manner the throttle valve A is gradually closed. By means of the segment D, as will be easily perceived, the result is attained that the throttle-valve romains closed for a time, even when the clock-work moves farther on. In this manner a person may allow the burnt-through fire to remain with the throttlevalvealmost fully closed for some time before restoking. If the clock work be run down, it is wound up again by means of the handle G, the string or chain g of which is wound on the drum E in another direction than the stringf. By this winding up of the clock-work the chain b is wound up the circumference of the wheel O, and in this manner the throttlesvalve is immediately again opened.

In order to be able to easily alter as may be desired the lengths of time during which the clock -work is running down-that is, the period from one stoking to the otherthe following arrangement is made use of: The main driving-wheel l, Fig. 4, works by means of the

wheels

2, 3, 4c, 5, and 6 on the escapement-wheel 7. The verge Z2 is movable on its pivot, on which a forked arm 5 or crutchwire hangs downward and is itted to catch the lower part z of the pendulum. The pendulum consists of the well-known rod z, forming the lower part, and a rod fn, forming the upper part, connected with it by means of a spring-plate y. The latter rod at is inserted in the sheath IV, and may be fixed at any rcquired height by means of the screw 0:. In this way the duration of the swing of the pendulum, and therewith the time for the running down of the clockwork, may be very easily and simply varied. Any stoker can bring this about by a few simple turns of the handle as soon as a stronger or weaker firing is required.

In order that the stolzer may be notified each time that the throttle-valve is entirely opened or entirely shut, an arrangement is attached by which an alarm sounds when the clock-work is quite wound up and when, consequently, the throttlevalvc is entirely opened, and by which another signal sounds when the clock-work has entirely run down, and consequently the throttle-valve is entirely closed. For this purpose two pins Z and 71; are Iitted on the drum E, Fig. 5, of which pin acts on the arm o on the winding up of the clock-work and pin Zon the arm m on the IOL) running down of thc clock-work. The arm o is attached to the axle O, on which the arm o2 of the clapper of the bell U is iitted.

If the clock-Work be Wound up by means of the handle G, the pin 7o takes a position behind the arm o and presses the saine back in the direction ofthe arrow I, whereby the clapper of the bell U is moved to the left. The pin 7c is arranged on the drum E in such a manner that it slips from off the arm o shortly before the Weight F is quite drawn up. The clapper then strikes on the bell U and gives the lstoker the signal that the clockwork is wound up and the throttle-valve' is quite opened. On the running down ofthe clock-work, on the other hand, the pin Zcomes into action, catches behind the arm m of the M," and pushes the same to the left,I shown by the arrow I I. The arm on is thereby pressed downward and works by v ineansfofl'tliearm r, fixed on the cam R, in

- the paper disk.

such a manner on thek shank of the clapper t, movable on shaft 'I of the bell V, that the clapper is moved awayfrom the above-named bell'.A AVhen by. the continued motion of the drum E the pin Z slips away from the arm Im, the latter :swings back by reason of the action of a spring seated on the axle, and the bell V is struck by the cla'pper as a signal that the throttlefvalve is closed. In order to prevent a further. revolution of the drum, a pin 7L, Fig. 3, is provided on the same, whichv comes against the projection '1i as soon as the bell has been struck. Y

In order to always keep. an Yexact check on theiire'mainan arrangementisattached'which isset inaction on the striking of Vthe bells and which' makes corresponding holes on a paperdisk connected with an ordinary clock and set in motion by the same.

The/two prickers S" and S2, Fig. 5, are avr-Y ranged one above the other. The pricker S', which works on the winding of the" clock-A wdrk, is set in action in the. following manner: The pricker S is fastened on a sleevel?, vihiCll is loosely movable on the axle lll and is provided with an arm p. `An arm o', alt-` tached to the axle O, strikes against this arm p. It' now bythe winding of the clock-i work the arm o is pushed away by the pin k tothe riglit,the armo raises the arm p of the sleeve I), and the pricker S sticks into The other pricker S2., which must stick into the disk: on the running down ofv theclock-work, fixed on the axle N, which is provided with an arm n, projecting forward. A; short arm m2, attached to the axleM, works on this arm n, which arm Im2. onthe slipping avvayot' the pin Z'from` the arm m presses downward; The axle N makes then a slight revolving. movementan d the prio-ker Sfzsticks into a paper disk.

Of course several of the methods of con-V structing the various parts` can be altered or 5 replaced 'by others.

The clock-workdriven by a weight may be replaced by one driven by a spring. Further, the recording and alarm devices may be actuated in other ways and sound-signals may be replaced by sight Ones.

The connection of the drum C, especially with the throttle-valve A or with any desired slide, may be altered in numerous ways. In Fig. 6 this connection is brought about by a single chain,- which can be partially Wound on both rollers. In Fig. 7 the axle c and the axle a are each provided with an arm, and both arms are connected by a rigid rod. lVhcn a chain, which is wound upon the roller C and attached to anv arm of the axle ct, is used in this case equally with the arrangement de picted in Fig. G, counter-weights must be made to work on the throttle-valves axles. Finally, as depicted in Fig. S, the clockfwork could be inade to act direct on the throttlevalve.

In apparatus for automatically regulat ing the supplyof air to boiler and other fur naces, the combination, with a dampereclosing device arranged in the iiue oran-passage, of' clock-work mechanism comprising'a pendulum Q0 y e, a shea-ve `W,in which the upper part is contained, a dat spring @j for connecting the upper part a; with the lower part e, whereby the latter engages with a forked arm o r crutch e', connected with the pallet orl anchor of an escapement-wheel, and connections from the clock-.work to said closing device, substantially as and for the purpose Set forth.
