JOHN B. GOFF, OF WELLSVILLE, OHIO.

IMPROVEMENT IN FREIGHT-CAR DOORS.

Specification forming part of Letters Patent No. 156,633, dated November 10, 1874; application liled Y September 12, 1874.

To all whom it may concern:

Be it known that I, JOHN B. GOFF, of Wellsville, in the county of Columbiana and State of Ohio, have invented a new and useful Improvement in Doors for FreightCars; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My linvention relates to an improvement in doors for freight-cars; and consists in supporting the lower end of the door in a pivoted bearing, held in position with relation to it through the medium of a cam-lever.

To enable others skilled in the art to make and use my invention,I will proceed to describe more fully its construction and operation.

In the accompanying drawings, which form v part of my specification, Figure l is a front elevation of a section of a car provided with my improvement. Fig. 2 is a vertical section of the same at line y y of Fig. l.

In the drawings, A' represents a section of a side of a car, which is constructed in the usual manner. A represents the door of the car, which is held in position at its upper end by means of the guide B, the lower end being provided with metallic slides k, which rest upon the bearing O pivoted at h. The bearing C is constructed of angle or other suita ble iron. On the under side of the bearing G is arranged an eccentric, D, furnished with a handle or lever, f. The eccentric D is pivoted loosely at c, and the handle or lever f is supported on a hook, g. On the under side of the pivoted bearing C are arranged two supports, i. l represents the handle `for manipulating the door A.

The operation of my improvement is as follows: By unshipping the handle or lever f olf the hook g, and allowing it to drop down, the pressure of the eccentric will be taken on" the bearing C, which will drop down on the supports i, which will allow the door to slightly move downward, for the purpose of slacking its hold in the beveled groove or guide B, the upper end of the door being beveled to correspond to the bevel of the groove in the guide B. The upper end of the door, being loosened in the guide B and bearing C, can be readily moved sidewise by the operator taking hold of the handle l. When the door is closed, the operator, by taking hold of the handle f and raising it up, so as to place it over the hook g, will cause the eccentric D to raise the bearing C, which will force up the door A, so that its upper and beveled edge will be forced firmly into the bevel-groove of the guide B, thereby holding the door in a firm and fixed position with relation to the opening in the sides of the car, whereby the rattling, jarring, and sliding motion common to doors of freightcars is avoided.

What I claim is- The pivoted bearing C and eccentric D, in combination with the car-door A, the upper end being beveled, and moving in the bevelgroove of the guide B, substantially as described, and for the purpose set forth.

In testimony whereof I hereunto set my hand this 16th day of June, 1874.
