Specification forming part of Letters Patent No. 56,596. (lated July 24, 1866.

To all whom 'it may concern:

Be it known that I, JOSEPH M. NAGLEE, of Philadelphia, Pennsylvania, have invented an Improved Apparatus for Extracting Specimens of Liquors from Vessels, and I do hereby declare the following to be a tull, clear, and exact description of the same, reference being had to the accompanying drawing, and tothe letters of reference marked thereon.

My invention consists of an instrument, fully described hereinafter, for obtaining from casks and other vessels specimens of the coutents, the instrument having been designed with the view of superseding the old-fashioned and in many respects inconvenient apparatus alluded to hereinafter as having been hitherto used for the same purpose.

In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

The figure in the accompanying drawing represents a vertical section of the instrument t'or extract-ing specimens ot' liquor from vessels.

A is a tube, which is contracted at its lower end, and to the top of which is secured a valve-chest, a, an opening,x, in the latter communicating with the interior ot' the tube, and a valve, c, opening upward, being adapted to a seat in the chest, into which screws a hollow plug, b, the latter limiting the upward movement ot' the valve, and which is attached to the lower contracted end ot' an air-vessel, C, of rubberl or other elastic material, the upper contracted end of which is secured to a valvechest containing' a valve, c, which also opens upward, and which is confined within the chest by a hollow screw-plug, b.

To the side of the tube A, near the upper end ot' the same, is secured a handle, B, and in the tube above the handle is an opening, 1, which is closed by a valve, t, on 011e end of a f springlever, D.

The ordinary apparatus for extracting liquors from vessels, technically termed a liquorthiet,7 is open at the top, so that the operator can apply his mouth to the same and thus eX- haust the air, the opening being closed with the thumb after the tube is filled, and the thumb being removed when the liquor has to be discharged.

My invention has been designed with the view ot' superseding this primitive and in many respects inconvenient implement.

The air in the tube A being exhausted by alterna-tely compressing and releasing the elastic vessel C, which is grasped in the hand ot the operator after introducing the end ot Athe instrument into the liquor, the tube is quickly filled, and then lifted from the liquor by means of the handle B, the operator pressing on the lever D with his thumb, and uncovering the opening y whenever the contents ot the tube have to be discharged.

It will be seen that by the above-described apparatus specimens of liquor can be readily extracted Jfrom vessels with little or no inconvenience-to the operator, even when the vessels are in positions which would render the use of the ordinary apparatus impossible.

It will also be seen that by this apparatus specimens of poisonous liquors, acids, and other corrosive fluids can be obtained without detriment to the health ot' the operator, while, as the liquor -is not brought into contact with the elastic vessel, it cannot injure the latter.

l am aware that an elastic vessel provided with valves and communicating at each end with a tleXible conducting-tube has heretofore been used as a substitute for an ordinary syringe, this device beingshowu in the patent of B. Arnold, July l, 1861. It will be apparent, however, that an apparatus so constructed could not be used as a substitute for the apparatus above described, especially for obtaining specimens ot corrosive tluids.

I claim as my invention and desire to secure by Letters Patent- The combination ot' the reservoir-tube A and its valve t with the elastic air-vessel C and its valves c c', the whole being` constructed and operating substantially as and for the purpose described.

In testimony whereofl I have signed my name to this specification in the presence of two subscribing witnesses.
