UNITED STATES WILLIAM G. CREAMER, OF BROOKLYN, NEW YORK.
IMPROVEMENT IN RAILROAD-CAR VENTILATORS. I
Specification forming part of Letters Patent No. 123,770, dated February 20, 1872.
Specication describing certain Improvements in Automatic Ventilators, invented by WILLIAM G. CREAMER, of Brooklyn, county of Kings, State of New York.
My invention consists in arranging the pivts of automatic ventilators in such a way that,
' in shifting back and forth by changing or bafing currents of wind, the movement of the deectors shall be noiseless.
I am the inventor of a system of automatic ventilation adapted for railway cars; and it consists in providing an opening in the side of l-the car near the top, in which is placed a movable deiiector, projecting outward about three inches, and capable of assuming an angle of buildings, or sheds, the blinds are shifted back.
and forth rapidly, and make a very disagreeable noise. So much has this been an ob- `)eetion` that inmany cases the use of my ventilators has been abandoned on sleeping-cars. Figure 1 represents one of my ventilators complete. bis the movable deilector. co a a, 'A
is the tin box or frame that is inserted in the Wall of the car, and at the top e and bottom h is placed a pivot. At the top of the blind, at
g, is attached a small tube; at the bottom, at h, a similar tube. In this tube, at top and bottom, is inserted a bushing of India rubber, cloth, cork, or other elastic substance. At the bottom of the tin box, at 7c, is also attached a piece of rubber or other elastic substance, against which the blind strikes.
Fig. 2 is a cross-section of the blind, and shows the bearings.
Fig. 3 is the blind or deiiector alone, showing the tubes j g and k h.
Fig. 4 is the top bearing that attaches to the frame, which also has a bushing of rubber, shown at fi c', Fig. 9.
Fig. 5 shows the bottom pivot d that is attached-to the frame. This pivot isdiixed, and the tube inserted in the bottom of the blind containing the rubber slips over it. The rubber bushing for this is shown at Fig. 11, 7c k.
Fig. 8 is the top pivot, which is loose, to remove the defiector, if required.
Fig. l0 shows the bushing for this. l
Figs. 6 and 7 show the openings (full size) that are out into the deiiector.
What I claim as my invention is- The insertion of elastic substances around the pivots and in the bearings of automatic ventilators, to render the movement of the deflectors noiseless.
