DEFLEGTING-PIIATE FOR SMOKE-FL'UES.

lowing is a full, clear, and exact description. It is well known to those skilled in the art that it is customary to connect smoke flues to the smoke-stack with a right angle bend and as this connection is at the point where theflue gas temperature is the lowest, objectionable limitations are placed .upon the draft through the flue. In view of this it is often necessary to increase the height of the stack in order to overcome the resistance caused by this right angled bend.

I have overcome the disadvantages above enumerated by providing" a device which eliminates this sharp right angled connection, thus greatly increasing the strength of the draft by reducing the resistance offered thereto.

Moreover, by the use of my invention the height of the smoke-stack may be materially reduced.

Furthermore, I have sought to provide a device which shall be simple and cheap to manufacture and one which may be easily installed.

I have accomplished the advantages above enumerated by the device shown in the accompanying drawings, in which:

Figure 1 is a plan view of the device.

Fig. 2 is a sectional elevation of the same in its normal position.

Fig. 3 is a sectional elevation of the device shown in its lowered position.

Fig. 4 is a diagrammatical view of a modified form of my device.

Referring to the drawings and more particularly to Figs. 1 to 3 inclusive, 5 represents a smoke-stack and 6 a smoke flue connected therewith. 7 is my deflecting plate which is disposed within the stack 5 and arranged immediately below the flue 6. The plate comprises a stationary plate member 8 and a movable plate member 9. Each of these plate members are preferably provided at their adjacent edges with hinge parts, through which an operating shaft 10 passes. The stationary plate member 8 is curved upwardly so as to deflect the smoke and gases coming from the flue 6 and direct their path up the stack without adding Specification of Letters IPatent.

10 passes through the stack 5 and is pivot-' ally disposed within the hinge part 'of the stationary plate member 8. The hinge part of the movable plate member 9 is rigidly secured to the operating shaft 10 so that when the shaft is rotated the movable plate member 9 may be rotated therewith. Rigidly disposed on the outer end of theoperating Patented May 29, 191 '7. Application filed August 23, 1916. Serial No. 116,455.

shaft 10 is an operating arm 11. Mounted I upon this arm is a counter weight 12 which 1s soproportioned and adjusted that the movable plate member 9 is normally held in the position shown in Fig. 2. In Figs. 2 and 3 the operating arm ,11 and counter weight 12 are shown in broken lines because they are disposed upon the part of the stack which, in these sectional views, is removed.

In Fig. 4, where I show a modified form of my device, the movableplate member 14 is preferably curved so that it has the same radius as the stationary plate member 8 and is not provided with the soot pocket as is the form shown in the other figures.

It will be clearly seen that, when my deviceis installed, the products of combustion coming from the smoke flue 6 (in the direction of the arrows in Fig. 2) will strike the curved plate members and be' deflected upwardly through the stack thereby eliminating the friction common in right angled connections. All the soot which accumulates in the stack and upon the stationary plate member 8 will fall on to the plate member 9 and into the soot pocket 13 thereof. At any time that this accumulation becomes excessive, the operating arm may .be raised which will move. the plate member 9 to the position shown in Fig. 3 where the soot will be dumped from the pocket 13.

It is obvious that, while my device is shown in connection with a round stack, it may be used with equal efficiency with a stack of any other shape. Furthermore, if desired, the stationary plate member 8 and the movable plate member 9 may be made integral or rigidly connected so that both will operate when the operating shaft 10 is rotated. These and other modifications of the details herein shown and described may be made without departing from the spirit of my invention or the scope of the appended claims and I do not, therefore, wishto be limited to the exact embodiment herein shown and described. 1 7

Having thus described my invention, what I claim is:

1. The combination with a smoke-stack and a smoke flue of a deflecting plate, said plate comprising a stationary plate member and a movable plate member, and means for controlling said movable plate member.

2. The combination with a smoke-stack and a smoke flue of a deflecting plate, said ,plate comprising a stationary plate member idly' connected to' said movable plate member.

4. The combination with a smoke-stack and a smoke flue of a deflecting plate, said plate comprising a stationary plate member and a movable plate member, said movable plate'member being provided with a pocket for the accumulation of soot, and means for operating said movable plate member, whereby the soot may be dumped therefrom.

5. The combination with a smoke stack and a smoke flue of a deflecting plate, said plate comprising a stationary plate member and a movable plate member, an operating shaft passing through the stack and pivotally mounted therein, said shaft being rigidly connected to said movable plate member, an operating arm secured to said shaft, and a counter weight adjustably mounted upon said arm, whereby said movable plate member may be operated.

In testimony whereof, I have hereunto signedmy name in the presence of two subscribing'witnesses.
