IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 167,128, dated August 24, 1875, application filed August 12, 1875.

OAsE B.

To all whom it may concern:

Be it known that I, BENNETT B. SC NEIDER, of the city, county, and State of New York, have invented a new and useful Improvement in Lamps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawing, which'forms part of this specification.

This invention relates to that kind of lamp which has an oil-reservoir with a valve in the bottom, and is placed in a case or receiver, in which it is supported at a level higher than the burner. This reservoir is made removable, and so that when taken out of its receiver and inverted it may be filled with oil through its valve, and when turned top side up again and inserted to its place in the receiver the latter is supplied with oil through the valve in the reservoir. The invention consists in a combination of a catch applied tolock the reservoir when inserted to its place in the receiver, and a spring-valve applied to the bottom of the reservoir, whereby, on liberating the catch to remove the reservoir, said valve is automatically closed to prevent the escape of oil from the reservoir when drawing the latter out from the receiver, and whereby, when the reservoir is inserted to its place in the receiver and locked by the catch, the valve is automatically opened to supply the receiver with oil.

In the accompanying drawing, Figures 1 and 2 represent partly broken sectional elevations of a lamp-reservoir and receiver in different positions as regards the reservoir, valve, and catch. Fig. 3 is a transverse section on the line a: a.

A is the receiver, which connects with the wick-tube of the lamp by an outlet, b. The receiver A may be of cylindrical construction, and receives freely down within it the reservoir B, which is withdrawn and inverted for filling through an opening covered by a valve, 0, in its bottom. This valve, which may be a simple disk, or of any other suitable consiruction, has its closing action controlled by a -springas, for instance, by a spiral spring, 0, arranged around an inner or back stem of the valve, and bearing at its one end against a bridge in the reservoir, so that in commencing to withdraw the reservoir from the receiver the valve is automatically closed, and

kept tightly shut till purposely opened after the removed reservoir has been inverted for filling. The filling may be effected by inserting the spout of a filling-can down within an overflow cup, 01, outside of the valve, and pressing the same against the valve, so as to open it. The valve 0 is automatically opened, when the reservoir is inserted to its place within the receiver, by causing the valve to come in contact with the receiver A-a-s, for instance, either by an outer extension of the valve striking the bottom of the receiver, as shown in the drawing, or by the face of the valve striking a fixed stem or projection within the receiver. This automatic opening and closing of the valve, however, is subject to the control of a catch applied to lock the reservoir when in place within the receiver, with the valve in the reservoir open, but so that when said catch is liberated to remove the reservoir the "alve is automatically closed, to prevent the escape of oil from the reservoir when drawing the latter out from the receiver.

This catch may be variously constructed and applied. Thus, it may either be a springcatch or any other catch, and the male portion of it either be on the reservoir or on the receiver, and the female portion to correspond but, for the purpose of illustration, a springcatch, or male portion D thereof, is here shown as applied to the receiver A, and so that the same is operative from the exterior of the receiver, to automatically lock with the reservoir by overlapping a circular rib, f, on the reservoir when the latter is down to its place, but so that when said catch is withdrawn the reservoir B is free to be drawn up or to be thrown up by the valve-spring, and the valve closed, as clearly shown in Fig. 2 of the drawing, after which the reservoir having the valve closed may be wholly removed from the receiver.

I claim The combination of a catch applied to lock the reservoir when inserted to its place in the receiver, and a spring-valve applied to the bottom of the reservoir, substantially as specified.
