GEORGE WILLIAMS, OF MYSTIC RIVER, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO WVOLCOTT B. M ANWARING, OF NEW LONDON, CONNECTICUT.
SPARK-ARRESTER FOR CAR-WINDOWS.
SPECIFICATION formingpart of Letters Patent No. 228,847, dated June 15, 1880.
Application filed November 29, 1879.
To all whom it may concern Be it known that I, GEORGE WILLIAMs, of Mystic River, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Spark- Arresters for Car'Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apro pertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
The object of this invention is to prevent I 5 cinders, smoke, and sparks from entering the windows of a moving car without obstructing the view through such windows. This object is effected by the employment of devices hereinafter set forth and claimed.
In the accompanying drawings, Figure 1 represents a side view of a railroad-car provided with my improved devices for protecting the windows against the intrusion of sparks and cinders. Fig. 2 represents an en- 2 5 larged view of one window and the adjacent part of the car, the shields or protecting (le vices being turned flat against the same. Fig. 3 represents the same view as Fig. 2, except that one of the shields is thrown back into protective position as if by a blast of air. Fig. 4
' represents a detail view of one of the upper brackets and stops, and Fig. 5 represents a top view of the shields.
A designates the side of the car, having windows B. On each side of each window is a pair of brackets, C C, the upper bracket of each pair being bifurcated, as shown in Fig. 4, and provided on the face of the lower ends of its forks with stop-blocks D D. In each pair of brackets C C is journaled one of two sparkarresting shields, E E, which are shaped like longitudinal strips or sections of a cylinder, and have their convex sides toward the window between them. These shields can play freely on their pivots in said brackets; but said stops D, which may be of any elastic or pad-like material, prevent said shields from striking violently against the side of the car. These shields may readily be turned toward the side of the car, so as to present the convex side of each shield outward.
When the car is drawn in either direction the resulting draft of air under the forward shield will act on its concave face so as to throw it over on its journals toward the window, as shown in Fig. 3. It then presents to the blast of air its concave face, standing out some dis-- tance from the side of the car, and catches therein the sparks, cinders, 8210., which are carried back by the current.
To prevent any small cinders from sifting through the space between the side of the car and the proximate edge of the shield, this space may be guarded by a strip, F, which extends as shown.
The shields and the guard-strips may be made of any suitable material; but metal is decidedly preferred.
When the motion of the car is re 'erscd the draft of air throws open the opposite shield and closes the one previously opened. These shields effectually protect the car-windows from the intrusion of cinders, sparks, 850., and exclude nearly all the smoke, but they do not in the least obstruct the outward view.
It is obvious that the stops or pads D may be attached to the sides of the car instead of to the brackets.
Various other changes may be made without departing from the spirit and scope of my invention.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A car-window provided with two concavo-convex shields journaled in fixed bearings, one shield being on each side of said window, and arranged in such manner that the draft of air as the car moves will hold one 0 shield nearly parallel to said car with the convex side outward, while the other shield will be held at a slightly-projecting incline with it's concave side to the draft.
2. In combination with a journaled con- 5 cavo-convex shield, E, and lower bearing, C, the upper bearing, C, provided with two downwardly-extendin g widely-divergin g arms, each from the upper bracket to the lower bracket, 65
jarring it.
of which is provided on its face with a thick In testimony that I claim the foregoing I pad; 1), of soft material, allowing the shield have hereunto set my hand and seal this 24th 10 to be turned nearly parallel to the car without day of November, A. D. 1879.
3. In combination with a hinged window- GEORGE WILLIAMS shield, a strip or plate for guarding the space 5 Witnesses: between the side of the car and the proximate LEMUEL OLIFT, edge of the shield, substantially as set forth. WALTER O. MORGAN.
