WILLIAM M. IL THORNTON, or' ROLLA, MISSOURI.
Lette/rs Patent No. 101,787, lated April 12, 1870.
` The Schedine referred to in these Letters Patent and making part of the same.
Fo all whom it may concern Be it known that I, WILLIAM M. K. THORNTON, of Rolla, in the county of Phelps and State of Missouri, have invented a new and improved Dust and Cinder-Arrestcr for Railroad-Gar Windows; and I do hereby declare that the following is a full, clear, and
exact description thereof', reference being had to the accompanying drawings making part of this specification, in which- Figure 1, plate 1, is a side elevation of a'passengerca'r having my improved arrester applied to the windows thereof.
Figure 2, plate 1, is an enlarged view of a window and arresters.
Figure 3, plate 1,'is a top view of iig. 2.
Figures 4 and 5, plate 2, are enlarged views of the arresters. A
Similar letters of reference indicate corresponding parts in the several figures. l
This invention relates to an improvement on the guard-plates or shields, which have been hitherto applied to car-windows for the purpose of preventing the entrance into the car of dust and cinders when the window-sashes are u p.
The object of my invention is to improve windowshields or guards by constructing upon their hinged edges wings or blades, which shall serve a two-fold purpose, to wit, to make the shields seliadjusting, and also to hold the shields on those sides of the windows in the direction of movement of the train perpendicularly to the sides ofthe car, or in operating position, as will be hereinafter explained. y
To enable others skilled in the art to understand my invention, I will describe its construction and operation. l
In the accompanying drawings- A represents a window-frame of the car-body' B. To each vertical side of the frame A, on the outside .of the car, one of my improved double-acting shields is applied. The shield on the two sides' of the window are so applied that only one of them will operate at a time.
' The shield C is a flat plate, of a rectangular form, orof any other suitable form, and of a length somewhat greater than thel height of the opening left when the car-window is fully open.
The shields has constructed on one edge two eyes, a a, and an intermediate right-angular wi ng,lD, as clearly shown in figs. 2, 3, 4, and 5.
By'means of the two eyes the shield and its wing can be readily connected to the side of the car, for
which purpose a pintle, b, and two eye-pieces, c c, are employed. The pintle b is in an upright position, that is to say, it is parallel to the vertical sides of the window-frame; consequently the shields and its wing wili swing horizontally.
In the construction of the shield and wing it is essential that the relative proportions o f the parts should be observed, and that "the shield be made to present such a supercial varea to the wind as will cause the currents impinging against it, when it is perpendicular to the side of the car, to adjust the shield to said position.
As above stated, Il employ t-wo arresters for each window, and so arrange them that when one is moved out of operation by the force of the currents of air acting on the shield of this'one, the other one will be instantly moved into operationl by currents acting on its Wing, and thus starting its shield from a position parallel to the side of the car.
I am aware that shields have beenv hinged to carwindows for arresting cinders and dust before my in-- vention, but such contrivances were not made selfacting or self-adjusting by means of wings D, formed on their hinged edges, as abovedescribed.
The wing D being arranged at right angles to the .shield C, it is obvious that the former will also operate as a stop or brace to keep the shield perpendicular to the side of the car, in operating position.
-I am aware that, in a patent granted to Edwin Norton, .December 21, 1869, and -also in an application which is pending before the United States YPatent Oliice and ordered to issue January 6, 1870, car-ventilators are shown and described which have stops applied to their hinged edges insuch manner as to hold the ventilator-plates, when in working position perpendicular to the sides of the car.- But these stops differ from mine in that they do not serve the purpose of wings and operate as above described. I do not, therefore, claim as my invention the contrivanoes above referred to.
Having described my invention,
What Iclaim as new, and desire 'to' secure by Letters Patent, is-
A self-acting dust and cinder-arrester, consisting ot a shield, C, a wing, D, and eyes 'a a, constructed to operate substantially as described. y
