WILLIAM E. WINE, OF TOLEDO, OHIO, ASSIGNOR TO THE WINE RAILWAY APPLIANCE COMPANY, A. CORPORATION OF OHIO.

CAR-VENTILATOR.

Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed November 19, 1917. Serial No. 202,791.

To all whom it may concern:

Be it known that 1, WILLIAM E. WINE, a citizen of the United States, residing at T- ledo, in the county of Lucas'and the State of Ohio, have invented new and useful Improvements in Car-Ventilators, of whichthe following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to new and useful improvements in ventilators for freight cars and to that type of ventilator shown in patent granted me October 1st, 1912, bearing Serial Number 1,040,084.

The object of my invention is to provide a ventilator that incorporates all the advantages of my previous ventilator and with a further additional advantage of having tighter sealing joints.

lVith these and other objects hereinafter explained in view, my invention cons sts in the construction and combination of ele- Inents hereinafter described and claimed.

' closed position; Fig. 3 is a partial section on line 2-2 showing the shutters open; Fig. 4 shows a modification, in part, similar to Fig. 2; Fig. 5 shows still another modification; Fig. 6 is a section on line 66 of Fig. 2; Fig. 7 is a section on line 7-7 of Fig. 5; Fi 8 is a section on line 8--8 of Fig. 4.

imilar characters designate similar parts throughout the several figures of the draw- 1n s.

eferring now to the parts by number:

The frame is composed of sides 1, top bar 2 and bottom bar 3. The opening between the sides and top and bottom bar is opened and closed by shutters which are operated by operating bar 5. The operating bar 5 is connected to shutters 4 by means of lugs 6 and pins 7. The shutters 4 are pivoted on trunnions 8 in pockets 9 located on sides 1 tothe frame. The shutters 4 are provided along their upper edge with a rib 10 which extends vertically above the bottom edge 11 of the shutter immediately above, when closed.

The sides 1 are provided with sealing ribs 12 which are parallel to the inner surface of the shutters 4. The shatters 4 are provided with arms 13 to which are attached the trunnions 8. The arms 13 are also provided with sealing ribs 14 which are parallel to the inner surface of ribs 12.

The top bar 2 of the frame is provided with a depending rib 15 which is adapted to engage rib 10 on the top shutter. The bottom bar 3 is provided with an upwardly extending portion adapted to engage the bottom edge 11 of the bottom shutter. The bottom bar 3 is also provided with a member 16 extending horizontally therefrom for engagement with the locking bar 17. The locking bar 17 is provided with a slot 18 in its top end and a slot 19 in its bottom end for the purpose of engaging the member 16 when the shutters are in their closed and opened positions respectively.

This locking bar 17 is pivoted to connecting bar 5 by pin 20, and is provided with holes 21 and 21 which gage with a hole 22 in the member 16 when the shutters are in their closed and opened positions respectively.

It will thus be seen that in order to open the shutters from their positions as shown in Fig. 2 to their position shown in Fig. 3, it is necessary to revolve the bottom end of the locking bar 17 upwardly into a horizontal position until the upper slot 18 disengages the member 16 on bottom bar 3. Then the shutters can be revolved to their open downwardly to the vertical position shown in Fig. 3 with the slot 19 engaging the member 16 and hole 21 gaging with hole 22 ready for their reception of any suitable locking'or sealing device.

In the modification shown in Figs. 5 and 7, the shutters 4' are almost identical with the shutters shown in Fig. 2, the only difference being the elimination of trunnions 8, the sealing rib 12' serving as a guide for the shutter.

The modification shown in Figs. 4 and 8 is an obvious 'eYfpedieiit, it being only a transosition of elements from that shown in Fig. 5, the ribs23 and 24 being located on the sides of the frame and incloses the ends of the shutters for guiding them into their opened and closed positions.

By eliminating the trunnions 8 it is possible to use intermediate members 25 between the sides which add materially to the strength of the frame. These intermediate members 25 can be made of any convenient shape.

It Will be understood from this description that although the improvements in this invention are simple, they accomplish in a thoroughly practical manner all the objects sought.

ll Wish it further understood that I do not desire to be limited to the specific construction or arrangement of elements shown and described, as it is obvious that changes in construction and arrangement may be made Without departing from the spirit of the invention.

Having thus described my invention, 1 aim in the appended claims to cover all modifications Which do not involve a departure from its spirit and scope.

What I claim as new and desire to secure by Letters Patent of the United States is:

1. A Ventilator comprising a frame member, a plurality of shutter members operable in said frame member and moving in an arcuate path, a plurality of guiding and sealing ribs on one of said members so that, counting shutter, three thicknesses of metal at the ends of each shutter are disposed between the inner and outer sides of the ventilator.

2. A ventilator comprising a frame member, a plurality-of shutter members mounted in said frame member and moving in an arcuate path, a plurality of sealing and guiding ribs on one of said members, said ribs ters mounted in said frame and adapted to move in an arcuate path, an arcuate rib disposed opposite the ends of each shutter and two arcuateribs formed on the sides of each shutter to inclose the 'rib on the frame to thereby accurately guide each shutter in its movement and present a double sealing ac tion to the edge of the shutter, and means for operating the shutters simultaneously;

4. A ventilator comprising a frame, arcuate shutters mounted in said frame and operable in an arcuate path, guiding means mounted on said frame and guiding means formed on said shutters at their sides to cooperate With the said first-mentioned guiding means, said guiding means on both the frame and on the shutters also forming a double seal for the shutters at their ends, means for operating the shutters and means for holding the said shutters in their open and closed position.

This specification signed and. witnessed this 17th day November, 1917.
