METHOD 0F AND APPARATUS FOR VENTILATING RAILWAY-CARS.

SPECIFICATION forming part o Letters Patent No. 35 9,761,dated March 22, 1887.

Application filed April 2?. ISES.

To @ZZ wtom, it may concern:

Beit known that I, Hman R. ADAMS, of Boston, in the county of Suffolk and State of lirlassachusetts, have invented a new and Improved Apparatus for Ventilating Railway- Cars, of which thc following is a full, clear, and exact description.

The invention will first be described, and then specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in ali the figures.

Figure I is a view taken from the interior of the car, representing the sash as thrown to the open position. Fig. 2 is a sectional plan View taken on line y y of Fig. I. Fig. 3 is a view taken from the outer side of the sash, the greater portion ol' the outer half of the sashframe being removed to disclose the construction of the double-hinging attachment. Fig. 4 is a vertical cross-sectional view taken on line n: @o of Fig. 3. Fig. 5 is a view of the sash as it appears when open from a position outside of the car and behind the sash, certain portions being broken away and shown in section. Fig. 6 is a view of a modified arrangement of the operating mechanism; and Fig. 7 is a view ofthe upper-portion of the partiallyopen sash, representing a modied arrangement of the screen.

In constructing a sash, such as the one illustrated in the drawings above referred to, I provide asash-ranie, I0, made up of two similar sections, that are united by bolts, screws, pins, or by any other means desired, the meeting faces of the two sections being properly recessed in order to receive such a mechanism as will now be described.

In the recess at the lower portion of the two sections of the sash-frames I mount a central lever, 11, that is provided with a handle, 12, the said handle being arranged upon the inner face of the sash. The lever Il carries two pins, 2 2, which ride in slots 3 3, formed in the ends of levers 13, which are centrally connected to the sash by mea-ns of pivot pins or bolts 1-1. The outer end of each of the levers 18 is slotted, as shown at et. In the recesses between the meeting faces of the two sections of the sash, upon either side of the glass, there are arranged vertical sliding rods 1G, which Serial No. 200,293. (No model.)

are formed with pins or pintles 5 and 6, that are arranged to pass through apertures formed in metallic boxiugs 7, that are carried by the sash, lugs S and 9 being fixed to the windowcasingin such position that when the sash is closed they will enter the boxings 7, there to be engaged by the pintles 5 and 6, as clearly shown. The lower end of each of the sliding bars 16 is formed with an angular projection, I7, which projections tit within the slots 4, formed at the ends of the levers I3. rlhe bars 16 are normally held in the position in which they are shown in Fig. 3 by springs I8, said springs being coiled about the bars and arranged so that one end will abut against the collar I9 carried by the bars, while the other end will abut against a guiding-stop, 20, through which the bars pass, which saidguiding-stop is fixed to the-sash.

From the construction described it will be seen that byturning the handle I2 the lever l1 will be moved so as to throw the inner end of one of the levers, I3, down, while the inner end of the other lever will be thrown up,wheu the rod in engagement with the slotted end of the levers I3, the inner end ot' which has been thrown down, will be raised and its pintles 5 and 6 will be thrown out of engagement with the lugs 8 and 9, while the pintles upon the other rod, I6, will be depressed and will serve as hinge-pintles upon which the sash will be free to swing. In order that the sash may be held in any desired position, I provide each of the lugs 9 with a metallic strip, 2l, that is provided with recesses 22, said recesses being formed in the outer or upper surface of the bar. These bars 21 are hinged to the lugs 9, the lugs extending outward through the sash, and the hinge 23, by which connection between the parts is established, being so placed that the bars will be free to drop to the position shown in Fig. 4 when the sash is closed; but as the sash is opened the bar upon that side of the sash which is swung outward will be dra-wn up to the position shown in Fig. 5, and the pintle 5 may be dropped into the re4 cess adapted to hold the sash in the required position.

In order that cinders, dust, smoke, tbc., may be prevented from entering the oars through the open space above the window, I provide such a construction as is best shown in Figs.

4 and 5, wherein I illustrate a series of telescopically-united box-like structures,of which the inner one, 25, is secured within a recess, 26, formed in the window-casing above the sash, the said inner section, 25, being provided with anges, by means of which connection is made with the casingwscrews or other proper retaining devices being passed through the said iianges. In connect-ion with theinner section, 25, I employ intermediate sections, 27, and an outer section, 28, which said outer section is provided at either end with a strap or loop, 29, that is engaged by a clip, 30, carried by the sash, said clips being arranged upon the upper face and at each end of the sash.

The several sec-tions of the telescopicallyjointed screen are united by cords 3l, which prevent the undue unfolding of any two of the sections, acting to distribute the motion equally throughout all the sections.

If desired, a screen similar to the one described could be arranged below the sash. In Fig. 7 I show a inodied form ofscreen,which consists of a strip of leather, cloth, or` any other proper material, 35, that is secured `to the upper edge of the sash and passes inward and over a roller, 36, fixed in the casing above the sash, the inner edge of the strip 35 being secured to elastic bands 37 that are made fast, as indicated, so that as one side of the lever is thrown up the strip'35 will also be drawn out to cover the opening and preventthe entrance of smoke, cinders, &c.

In Fig. 6 I illustrate a construction wherein the vertical rods 16 are arranged to be actuated by handles placed upon either side of the sash, and in this case the lower lever shown at would be pivotally connected to the center of the sash, and would not be divided as in the case of the levers 13, connection between the rod 16 and the handle being established through the medium of the lug or arm 40.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isr 1. The combination, with the frame having upper and lower recessed lugs,of the sash provided at its opposite sides with recesses to re- .pressing said rods downward, pintles `on opposite sides of the rods parallel therewith and extending through the apertured boxes and into the said recessed lugs, levers pivoted to the lower rail of the sash and engaging the lower ends of `the vertical rods with their outer ends, and a central lever engaging the inner ends of the said levers and `provided with an operatinghandle, substantiallyas set forth.

3. The combination of the frame having the upper and lower recessed lugs and bars pivotally connected to the outer ends of one of said lugs at each side ofthe frame and having a series of recesses with the verticallysliding rods having upper and lower pintles which engage the said recessed lugs,the pintles i engaging the lugs to which the recess-bars are pivoted being adapted to engage said` bars when they are extended by the outward move ment of the sash, substantially as set forth.

4. The combination, with asash adapted to be swung outwardly at either side of the extensible screen connected at its inner end to the frame and at its outer end to one edge of the sash, substantially as set forth.

5. The combination, with the frame having a telescopic screen the inner sectionof which is connected thereto, of a doubly-swinging sash to one edge of which the outer section of the screen is secured, substantially as set forth.
