EXHAUST STACK CONTROL Filed Feb. 21, 1941 Q, 55 Y 1i 1 30 35 E I o I 98a I f r! 4 i ii I Patented May 30, 1944 UNITED STATES PATENT OFFICE 2,350,102 EXHAUST STACK CONTROL Philip R. Fairbanks, Ogden, Utah Application February 21, 1941, Serial No. 380,062
1 Claim.
My invention relates to exhaust stack covers and for caterpillar tractors, Diesel powered shovels and all other types of internal combustion engines which are used in the open and which are provided with exhaust stacks subject to catching water, and has for its object to provide an automatic exhaust stack cover which will close when the engine is shut oif.
A further object is to provide a simplified stack cover which will be opened by the exhaust.
A still further object is to provide an exhaust stack cover which may be self opening and either controlled to close by manual operation, by operation of the throttle lever, or by electrical means. Also it is possible to close the stack cover by any other means which may be used to stop the motor or any lever or control that is moved or operated after the motor has been stopped insuring positive closing of the cover at all times when the motor is not running.
These objects I accomplish with the device illustrated in the accompanying drawing in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claim.
In the drawing Figure 1 is a side elevation of the top end of an exhaust stack showing manual control means for closing the cover.
Figure 2 is a view of the same stack showing how an electro-magnet may be employed to close the cover.
Figure 3 is a side elevation of a modified manner 01' closing the cover by control rods of the motor such as the shifting of the throttle rod or like control rods, or from any of the rods used in or on the engine which are shifted.
Figure 4 is a side elevation of a type of control which when mounted directly to the exhaust will control the cover' in a simplified manner.
This application is a continuation in part of my former patent application Serial No. 331,171, filed April 23, 1940, for Exhaust stack covers.
In the drawing I have shown my invention mounted on an exhaust stack E and secured around said stack by forming a band or clamp collar 30, said collar having the ends turned up to provide bearing supports or brackets for the pivot pin 3|, which pin supports the arm 32 of the stack cover F. The end of the arm 32 is extended and so pivoted that when the cover is opened by the exhaust gases the end of the arm will engage a catch 33. The catch 33 is pivoted in a bracket 34 extended below the collar 3| and the catch 33 is provided with a notch 35 in the topside thereof with a ramp formed to force the catch down as the stack cover is opened so that the end of the arm 32 will engage in and lock in the notch 35 holding the cover F open unt'l the catch has been released. A trip rod 36 is provided by which the catch 33 may be depressed to release the arm 32 from the notch 35, said rod 36 being carried on an extended end of the collar 30 in a semi-circular bracket which is riveted to the back side of the extended end of the collar. The top end of the rod 36 is bent at right angles at 31 extending through a slot in the bracket or collar with the end 31 adapted the each 33. This end 3! acts as a release lug and when the rod 36 is drawn downwardly it engages the lip 38 releasing the catch, to permit the cover to close. A spring shown in dotted lines may be employed to aid in closing the cover F, said spring being wound around the pin 3|,
or other types of spring means may be employed for this purpose.
An extended bracket 39 is provided depending from the lower side of the bracket 34 said bracket having the lower end turned inward or at right angles and perforated to permit the passage of the rod 36 therethrough said bracket 39 acting a guide for the rod 36. An enlarged washer or boss is i'orfned on the rod 36 near the top end of the bracket to normally hold the rod 36 elevated to its top position with the lug 31 at the top of the slot in which it is carried.
The catch 33 is provided with a tension spring 42 to hold the catch in the raised locking position and said spring is carried with one end engaging a dog on the lower side of the catch 33 and the other end supported on a tension rod or screw 4| mounted in the end of a depending bracket 40. The tension of the spring 42 may be adjusted by the tension screw to give the correct pressure on the bottom side of the catch 33 so that the catch locks the arm and cover in the open position with the correct amount of spring tension to prevent jarring or vibration of the exhaust stack from disengaging the catch.
The free end of the rod 38 may be attached to any of the control levers of the motor such as the throttle in such a manner that when the tractor or motor is shut off the rod is drawn down engaging the lug 31 with the lip 38 disengaging the catch 33 from the arm' ll 'releasing the bracket 44 below the lower guide rod 3!,so that when the electro-magnet is actuated by any source of electrical energy the catch will be released and the cover closed.
In Figure 3, I have shown the cover Fl pivoted at Sia with the arm. 32a extended and formed as an L shaped lever. This lever is slotted in an L form at 48 and the rod 3611,15 provided with the lug 31a carried in the slot 48. The lower end of the rod 36a is attached to a bell crank lever 49 which in turn is actuatedby a sliding rod 50, said rod being either the throttle rod or the magneto control rod.
In Figure 4, I have shown a device in which the exhaust stack is shown as E! and dispensing with the band shown in the other figures, I use a bracket 5 consisting of spaced wings 6 and 1 with extended ears 8 through which suitable bolts or screws are passed to hold the bracket to the stack E2. The arm 32b is pivoted between the two wings 8 and 1 on the shaft 9 and the trip or catch 33a is pivoted on the shaft It in the space betweenthe wings below the shaft 9. A coil spring S is-mounted with one end attached to the arm 32a and the other end attached to a wing on the end of the catch 33a. The trip lever 36a is the same as shown in Figure 1, thus the action of release is the same in Applicant is aware that modifications other than those shown may be utilized to operate the release rod 36 of his invention and such methods A are considered within the spirit of this invention bustion engines which are provided :with a vertical exhaust, the combination oi avertical exhaust stack; a cover for the top end of said stack to keep out the rain when the exhaust gases are not passing therethrough; a lever extending from one side of said cover substantially parallel therewith; a pivot pin through a hole in said lever; a bracket in which said pivot pin is mounted adjacent the top end of said exhaust stack; spring means carried on said pin to normally hold the cover closing the exhaust stack opening; an extension on said bracket; a'horizontally pivoted dog mounted on said extension, the latch of said dog being biased to engage the end of the lever to hold the cover 0 11 after having been forced open by the exha st gases; and a control rod mounted adjacent the dog to draw down upon the latch and release the lever for closing the stack when there are no exhaust gases passing therethrough.
