SPECIFICATION forming part of Letters Patent No. 411,6"/"7, dated September 24, 1889.

Application led July 1l, 1889.

To all whom it may concern,.-

Be it known that I, EDWARD L. PHIPPs, a citizen of thc United States, residing at Milford, county of Oakland, State of Michigan,

have invented a certain new and useful Improvement in Car-Doors; and I 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 pertains to 1o make and use the saine, reference being had to the accompanying drawings, which form a part of this specification.

In the drawings, Figure l is a side elevation of a car with one of my improvd cardoors, showing by dotted lines the same partly open. Fig. 2 is a side elevation of the same with parts broken away, and illustrating by dotted lines the operation ofthe mechanism.

My invention relates to that particular class of car-doors known as flush doors, which set into the side of the car flush with the outer surface of the car.

My invention consists of the peculiar combination of devices and appliances herein-- after specified, and more particularly pointed out in the claims.

A represents a car. B is its door. The door sets into the side of the car flush with its face, and the door-jainbs at the top, bottoni, and sides are preferably beveled, as shown at b, so that the door shall wedge closely into its seat.

C is the rail or rod along which the cardoor traverses as it is being opened. i 3 5 Brepresents hangers. They are attached to the door, and at their outer ends are journaled into the lower ends of the upright Suspenders D. These Suspenders loosely engage the rail or rod C at d, and a connecting-rod D serves to hold their upper ends in proper relation with each other.

E is a shaft extending across the doornear its top, and held by suitable clips c. At E is a crank, and at the ends of the shaft are crank-arms E2, the wristepins c2 of which engage with the Suspenders D by passing through slot-s d formed therein. The crank E is, by a pitman E3, engaged with the crankarm f of the opening-lever F.

5o G is a locking-bolt, likewise engaged with the crank f. It engages a suitable socket Serial No. 317,117. (No model.)

g upon the sill of the door. The opening-le ver F maybe provided with a slot j", adapted to engage over a hasp f2, and the whole may be locked by a padlock or any other usual appliance.

The operation of -the device is as follows: To open the door, the lever F is released and is lifted. This serves to draw the bolt G from its socket, releasing the bottom of the door. 6c The motion of the lever, also, by lifting on the pitman'Eg, raises the crank E. This throws back the crank-arms E2, and since they are resisted by the Suspenders D the result is to carry the top of the door outwardly from the car. This movement of the door, by reason of the engagement of its hangers B with the lower ends of the Suspenders, serves to swing the suspenders out at the saine time, thus serving to throw the door still farther out- 7o ward from its seat. Having raised the opening-lever F to its uppermost position, the crank f will have passed slightly beyond the line of resistance exerted upon it through the pitman E3, leaving the lever in a position 7 5 of stable equilibrium, The door having been thus lifted out from its seat beyond the face of the car, it is slid open along the rail or rod O.

.A stop C may serve to limit the movement in opening, and may also stop the door in 8o closing at the proper point opposite its seat. To close the door, it is slid to its place opposite the opening and the lever F is turned down. As it is thus turned it forces the locking-bolt G into its socket. It also pulls down the crank E. This throws forward the crank-arms E2, which, being resisted by the suspenders D, serve to crowd the door snugly into its seat. The lever F may now be suitably locked. 9o

It will be observed that the shaft E is located between the hangers B B and rail C. This arrangement gives to it, in connection with the Suspenders D, the peculiar compound leverage mechanism shown, whereby a small 9 5 rotation of the shaft serves to lift the door outward through a distance greater than the throw of the cranks E2.

I do not limit myself to the lever Fas a means for actuating the pitinan and so rotatloo ing the crank E', for this actuating mechanism may be considerably varied without departing from my invention; and I wouldhave my claims understood to comprehend as equivalents any suitable mechanism for aetuating the said pitlnan. The salne is true also of the means for actuating the lockingbolt G. v

What I claim isf l. The combination, with a ear-door and traversing rail or rod, of Suspenders depending from said rod and engaged with hangers upon the door, a shaft provided with cranks E E2, turned in opposite directions, the latter engaging through slots in the Suspenders,

a pitman E3, and crank-lever F, substantially as and for the purposes described.

2. The combination, with a car-door and its traversing rod, of hangers upon the door engaged with Suspenders depending from said rod, a shaft provided with cranksE E2, lo-

cated between the hangers and the rail, and in connection therewith a pitman and cranklever -for actuating said shaft, substantially as described.

The combination, with a ear-door and its rail, of hangers upon the door and suspenders depending from the rail, withwhich the hangers are engaged, a shaft provided with cranks E E2, the latter engaged with the suspenders by a slotted engagement, a pitman E3, crank-lever F, and locking-bolt G, substantially as and for the purposes described.

In testimony whereof I sign this specification in the presence of two witnesses.
