ject to construct a device for maintaining' the ventilator in any desired position of adjustment, and for holding said ventilator 1n a secure and firm position when so adjusted; and to construct a device Awhich is simple in operation, durable in construction, and cheap of manufacture.
Otherobjects willappear from a detailed description of the invention, which consists in the features of construction and combination of claimed.
In the drawings, Figure lis an outside view of the car Ventilating vwindows of the parts hereinafter described and type ordinarily used inthe construction of passenger cars; 2 a side view of the ratchet mechanism in its closed position;
Fig. 3 a view similar to Fig. 2, showing the .parts in position when the transom is in a partlylow red position; Fig. 4 a somewhat enlarged side view of the ratchet mechanism, partly in section; Fig. 5 a detail of the roller; and Fig. 6 a plan view of the arm for carrying the roller.
As shown in Fig. 1, the Ordinary car ventilating windows 7 are placed between fixed standards or supports 8 in thev construction ordinarily used 1n cars, and the ventilator 7 comprises a framework 9,' at one end'of which is attached a -pivotl() consisting of a plate 1,1 aliixed to the frame9 of the ventilating window, projecting from which is an ear 12 which engagesl a lug 13 attached to a plate 14, secured to the framework 8 lof the car body, and a pin projects from the ear 10 into the lug '13, forming a pivot for that end of the Ventilating window around which it swings. On the opposite end of the Application mea January a5, 1909. srial No. 474,053.
venti-lating frame 9 is attached the ratchet mechanism formaintaining the window in any desired position of adjustment. This mechanism comprises a fixed portion -15 which consists of a plate 16 attached to the framework 8 of the car body; andformed integrally with the plate 16, is a housing 17 which has its front and rear walls, attheir lowerend, cut away, and its side walls extending downwardly in a tapered formation, forming legs 18, the ends of which -are bent to form hooks 19..
The 'movable section 20 of the ratchet mechanism consists of a plate 21 which is secured to theframework 9 of the ventilator window. Formed integrally with said plate -is-a segmental portion 22 the base of which has formed thereon a hub 23 which has projecting therefrom trunnions 24, about which the hooked ends 19 of the legs 18 of thejlixed portion 15 are positioned. The curved portion of the segmental rack 22 has formed on' its face a'toothed, surface 25, which consists of `a series ofl round teeth 26 upon which a roller is adapted to travel. The roller 27 is carried between ears 28 formed integrally with a head 29 projecting* from the inner end of an arm 30. The arm` 30 is pivotally secured at its outer end 31 to the plate 16. And, passing through the head 29, is a rod 32, which is upset at its lower end 33, 4the upset portion being slightly countersunk into the head 29,v and the rod 32 is screw threaded at its upper end to receive a nut 34. Interposed between the head 29 and the top of the housing 17, and surrounding the rod 32, 1s a coil spring 35,
which holds the roller 27 under a spring tension against the surface of the toothed edge 25 ofthe segmental rack 22. It will thus be seen that as 'theroller 27 travels over the toothed surface 25' of the segmental rack,
when it strikes the depressions 1n the toothed surface of the rack, the roller being under the forcible spring tension that it is, will be held in a firm enough position to withstand the jars or vibrations ordinarily received in I the upper'vent'ilatmg windows of a railroad car.
By manipulation of the nut 34 the rod 32 can be drawn-upwardly, lcausing the roller 27 to be drawn upwardly therew1th,thus allowing the roller to contact only the upper portion 'of the'toothed surface of the segmental rack and making the window easy of manipulation.
It will be seen that when it is desired to open the windows for the purpose of ventilatingA the car, it will be possible, with this device, to open them all to the desired degree. When the windows'are fully opened, Vthey will turn down to a positiony at right angles to the vwindow casing, and the window's may be adjusted to intermediate posiof the window and create friction, whic would tend to wear out and -loosenup the parts. What I'claim as 'new and desire to secure by Letters Patent is: a
1. In a transom ratchet, the combination of a fixed'section and a movable section, the movable section adapted to travel with the transom and having a pivotal bearing in the fixed section, and means attached to the fixed section and kept in constant engagement with the movable section for retaining it in various positions, substantially as described.
